For Visual Studio 2017 and its new .csproj format

You can no longer just use Install-Package to point to a local file. (That's likely because the PackageReference element doesn't support file paths; it only allows you to specify the package's Id.)

You first have to tell Visual Studio about the location of your package, and then you can add it to a project. What most people do is go into the NuGet Package Manager and add the local folder as a source (menu Tools ? Options ? NuGet Package Manager ? Package Sources). But that means your dependency's location isn't committed (to version-control) with the rest of your codebase.

Local NuGet packages using a relative path

This will add a package source that only applies to a specific solution, and you can use relative paths.

You need to create a nuget.config file in the same directory as your .sln file. Configure the file with the package source(s) you want. When you next open the solution in Visual Studio 2017, any .nupkg files from those source folders will be available. (You'll see the source(s) listed in the Package Manager, and you'll find the packages on the "Browse" tab when you're managing packages for a project.)

Here's an example nuget.config to get you started:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <packageSources>
        <add key="MyLocalSharedSource" value="..\..\..\some\folder" />
    </packageSources>
</configuration>

Backstory

My use case for this functionality is that I have multiple instances of a single code repository on my machine. There's a shared library within the codebase that's published/deployed as a .nupkg file. This approach allows the various dependent solutions throughout our codebase to use the package within the same repository instance. Also, someone with a fresh install of Visual Studio 2017 can just checkout the code wherever they want, and the dependent solutions will successfully restore and build.

Here's my idea on how to fix this:

j = 19
def calc(y):
    global j
    try:
        j = j + 8 - y
        x = int(y/j)   # this will eventually raise DIV/0 when j=0
        print("i = ", str(y), " j = ", str(j), " x = ", str(x))
    except:
        j = j + 1   # when the exception happens, increment "j" and retry
        calc(y)
for i in range(50):
    calc(i)

Since I haven't seen an answer that deal with numerical and non-numerical attributes, here is a complement answer.

You might want to drop the outliers only on numerical attributes (categorical variables can hardly be outliers).

Function definition

I have extended @tanemaki's suggestion to handle data when non-numeric attributes are also present:

from scipy import stats

def drop_numerical_outliers(df, z_thresh=3):
    # Constrains will contain `True` or `False` depending on if it is a value below the threshold.
    constrains = df.select_dtypes(include=[np.number]) \
        .apply(lambda x: np.abs(stats.zscore(x)) < z_thresh, reduce=False) \
        .all(axis=1)
    # Drop (inplace) values set to be rejected
    df.drop(df.index[~constrains], inplace=True)

Usage

drop_numerical_outliers(df)

Example

Imagine a dataset df with some values about houses: alley, land contour, sale price, ... E.g: Data Documentation

First, you want to visualise the data on a scatter graph (with z-score Thresh=3):

# Plot data before dropping those greater than z-score 3. 
# The scatterAreaVsPrice function's definition has been removed for readability's sake.
scatterAreaVsPrice(df)

# Drop the outliers on every attributes
drop_numerical_outliers(train_df)

# Plot the result. All outliers were dropped. Note that the red points are not
# the same outliers from the first plot, but the new computed outliers based on the new data-frame.
scatterAreaVsPrice(train_df)

No, you'll need to do it manually.

function prettyDate(date) {_x000D_
  var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',_x000D_
                'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];_x000D_
_x000D_
  return months[date.getUTCMonth()] + ' ' + date.getUTCDate() + ', ' + date.getUTCFullYear();_x000D_
}_x000D_
_x000D_
console.log(prettyDate(new Date(1324339200000)));

You will not able to test the app using the Google-Play-Service library in emulator. In order to test that app in emulator you need to install some system framework in your emulator to make it work.

https://stackoverflow.com/a/11213598/1405008

Refer the above answer to install Google play service on your emulator.

No reason. Maybe the person who coded it came from PHP. It has the same effect as if you had named it "_item" or "item" or "item$$".

As a suffix (like "item$", pronounced "items"), it can signify an observable such as a DOM element as a convention called "Finnish Notation" similar to the Hungarian Notation.

Anyone looking for this functionality past 2018: it's much cleaner to do this with just CSS using position: sticky.

position: sticky doesn't work with some table elements (thead/tr) in Chrome. You can move sticky to tds/ths of tr you need to be sticky. Like this:

thead tr:nth-child(1) th {
  background: white;
  position: sticky;
  top: 0;
  z-index: 10;
}

Use jdbc:h2:mem:testdb as your path when logging into the H2 console.

Obviously if you have altered Spring Boot properties your datasource may be different, but it seems like you're struggling with how to find the default. That's all there is to it! You'll see your schema after logging in to H2.

With this method, your script doesnt have to wait for the background process, you will only have to monitor a temporary file for the exit status.

FUNCmyCmd() { sleep 3;return 6; };

export retFile=$(mktemp); 
FUNCexecAndWait() { FUNCmyCmd;echo $? >$retFile; }; 
FUNCexecAndWait&

now, your script can do anything else while you just have to keep monitoring the contents of retFile (it can also contain any other information you want like the exit time).

PS.: btw, I coded thinking in bash

function doParseCSVFile($filesArray)
    {
        if ((file_exists($filesArray['frmUpload']['name'])) && (is_readable($filesArray['frmUpload']['name']))) { 

            $strFilePath = $filesArray['frmUpload']['tmp_name']; 

            $strFileHandle = fopen($strFilePath,"r");
            $line_of_text = fgetcsv($strFileHandle,1024,",","'"); 
            $line_of_text = fgetcsv($strFileHandle,1024,",","'"); 

            do { 
                if ($line_of_text[0]) { 
                    $strInsertSql = "INSERT INTO tbl_employee(employee_name, employee_code, employee_email, employee_designation, employee_number)VALUES('".addslashes($line_of_text[0])."', '".$line_of_text[1]."', '".addslashes($line_of_text[2])."', '".$line_of_text[3]."', '".$line_of_text[4]."')";
                    ExecuteQry($strInsertSql);
                }               
            } while (($line_of_text = fgetcsv($strFileHandle,1024,",","'"))!== FALSE);

        } else {
            return FALSE;
        }
    }

My case is a bit special which VM option is not avaibale. I use x86 windows 7 system, my way of solving this problem is by doing following procedures:

1. File - Setting...
2. In "Build, Execution, Deployment" select "Gradle"
3. choose "Use default gradle wrapper (recommended)" in "Project-level settings"

After restart Android Studio problem fixed!

There is no inherent reason that a simple batch file would run in XP but not Windows 10. It is possible you are referencing a command or a 3rd party utility that no longer exists. To know more about what is actually happening, you will need to do one of the following:

• Add a pause to the batch file so that you can see what is happening before it exits.
  1. Right click on one of the .bat files and select "edit". This will open the file in notepad.
  2. Go to the very end of the file and add a new line by pressing "enter".
  3. type pause.
  4. Save the file.
  5. Run the file again using the same method you did before.

- OR -

• Run the batch file from a static command prompt so the window does not close.
  1. In the folder where the .bat files are located, hold down the "shift" key and right click in the white space.
  2. Select "Open Command Window Here".
  3. You will now see a new command prompt. Type in the name of the batch file and press enter.

Once you have done this, I recommend creating a new question with the output you see after using one of the methods above.

I used a deque... seems to work for me. This example has a vector, but you could skip that aspect and simply add them to deque.

#include <deque>

template <typename T>
double mov_avg(vector<T> vec, int len){
  deque<T> dq = {};
  for(auto i = 0;i < vec.size();i++){
    if(i < len){
      dq.push_back(vec[i]);
    }
    else {
      dq.pop_front();
      dq.push_back(vec[i]);
    }
  }
  double cs = 0;
  for(auto i : dq){
    cs += i;
  }
  return cs / len;
}



//Skip the vector portion, track the input number (or size of deque), and the value.


  double len = 10;
  double val; //Accept as input
  double instance; //Increment each time input accepted.

  deque<double> dq;
  if(instance < len){
      dq.push_back(val);
  }
  else {
      dq.pop_front();
      dq.push_back(val);
    }
  }
  double cs = 0;
  for(auto i : dq){
    cs += i;
  }
  double rolling_avg = cs / len;

//To simplify further -- add values to this, then simply average the deque.

 int MAX_DQ = 3;
 void add_to_dq(deque<double> &dq, double value){
    if(dq.size() < MAX_DQ){
      dq.push_back(value);
    }else {
      dq.pop_front();
      dq.push_back(value);
    }
  }
 

Another sort of hack I use occasionally is using mod to overwrite values in a vector.

  vector<int> test_mod = {0,0,0,0,0};
  int write = 0;
  int LEN = 5;
  
  int instance = 0; //Filler for N -- of Nth Number added.
  int value = 0; //Filler for new number.

  write = instance % LEN;
  test_mod[write] = value;
  //Will write to 0, 1, 2, 3, 4, 0, 1, 2, 3, ...
  //Then average it for MA.

  //To test it...
  int write_idx = 0;
  int len = 5;
  int new_value;
  for(auto i=0;i<100;i++){
      cin >> new_value;
      write_idx = i % len;
      test_mod[write_idx] = new_value;

This last (hack) has no buckets, buffers, loops, nothing. Simply a vector that's overwritten. And it's 100% accurate (for avg / values in vector). Proper order is rarely maintained, as it starts rewriting backwards (at 0), so 5th index would be at 0 in example {5,1,2,3,4}, etc.

You can update your jquery typings version like so

npm install --save @types/jquery@latest

I had this same error and I've been at if for 5 days surfing the net for a solution.it worked for me and it should work for you

I had the same issue (on windows server 2003), check in the IIS console if you have allowed ASP.NET v4 service extension (under IIS / ComputerName / Web Service extensions)

If you got here because a search engine told you this is how to get the Unix timestamp, stop reading this answer. Scroll down one.

If you want to reverse time.gmtime(), you want calendar.timegm().

>>> calendar.timegm(time.gmtime())
1293581619.0

You can turn your string into a time tuple with time.strptime(), which returns a time tuple that you can pass to calendar.timegm():

>>> import calendar
>>> import time
>>> calendar.timegm(time.strptime('Jul 9, 2009 @ 20:02:58 UTC', '%b %d, %Y @ %H:%M:%S UTC'))
1247169778

An excellent explanation of the uses of the underscore is Scala _ [underscore] magic.

Examples:

 def matchTest(x: Int): String = x match {
     case 1 => "one"
     case 2 => "two"
     case _ => "anything other than one and two"
 }

 expr match {
     case List(1,_,_) => " a list with three element and the first element is 1"
     case List(_*)  => " a list with zero or more elements "
     case Map[_,_] => " matches a map with any key type and any value type "
     case _ =>
 }

 List(1,2,3,4,5).foreach(print(_))
 // Doing the same without underscore: 
 List(1,2,3,4,5).foreach( a => print(a))

In Scala, _ acts similar to * in Java while importing packages.

// Imports all the classes in the package matching
import scala.util.matching._

// Imports all the members of the object Fun (static import in Java).
import com.test.Fun._

// Imports all the members of the object Fun but renames Foo to Bar
import com.test.Fun.{ Foo => Bar , _ }

// Imports all the members except Foo. To exclude a member rename it to _
import com.test.Fun.{ Foo => _ , _ }

In Scala, a getter and setter will be implicitly defined for all non-private vars in a object. The getter name is same as the variable name and _= is added for the setter name.

class Test {
    private var a = 0
    def age = a
    def age_=(n:Int) = {
            require(n>0)
            a = n
    }
}

Usage:

val t = new Test
t.age = 5
println(t.age)

If you try to assign a function to a new variable, the function will be invoked and the result will be assigned to the variable. This confusion occurs due to the optional braces for method invocation. We should use _ after the function name to assign it to another variable.

class Test {
    def fun = {
        // Some code
    }
    val funLike = fun _
}

GETDATE() returns current date and time.

If last year starts in midnight of current day last year (like in original example) you should use something like:

DECLARE @start datetime
SET @start = dbo.getdatewithouttime(DATEADD(year, -1, GETDATE())) -- cut time (hours, minutes, ect.) --  getdatewithouttime() function doesn't exist in MS SQL -- you have to write one
SELECT column1, column2, ..., columnN FROM table WHERE date >= @start

You can also take a look at the built-in .NET tracing facilities too. There's a set of trace listeners that allow you to output to a log file, but you can configure it to log into the Event viewer, or to a database (or all of them simultaneously).

I also got troubles with app using gradle 2.14, though with gradle 4 it's ok. By using --deviceID flag app instals without any issue.

react-native run-android --deviceId=mydeviceid

That particular phrasing is by James Iry, from his highly entertaining Brief, Incomplete and Mostly Wrong History of Programming Languages, in which he fictionally attributes it to Philip Wadler.

The original quote is from Saunders Mac Lane in Categories for the Working Mathematician, one of the foundational texts of Category Theory. Here it is in context, which is probably the best place to learn exactly what it means.

But, I'll take a stab. The original sentence is this:

All told, a monad in X is just a monoid in the category of endofunctors of X, with product × replaced by composition of endofunctors and unit set by the identity endofunctor.

X here is a category. Endofunctors are functors from a category to itself (which is usually all Functors as far as functional programmers are concerned, since they're mostly dealing with just one category; the category of types - but I digress). But you could imagine another category which is the category of "endofunctors on X". This is a category in which the objects are endofunctors and the morphisms are natural transformations.

And of those endofunctors, some of them might be monads. Which ones are monads? Exactly the ones which are monoidal in a particular sense. Instead of spelling out the exact mapping from monads to monoids (since Mac Lane does that far better than I could hope to), I'll just put their respective definitions side by side and let you compare:

A monoid is...

• A set, S
• An operation, • : S × S ? S
• An element of S, e : 1 ? S

...satisfying these laws:

• (a • b) • c = a • (b • c), for all a, b and c in S
• e • a = a • e = a, for all a in S

A monad is...

• An endofunctor, T : X ? X (in Haskell, a type constructor of kind * -> * with a Functor instance)
• A natural transformation, µ : T × T ? T, where × means functor composition (µ is known as join in Haskell)
• A natural transformation, ? : I ? T, where I is the identity endofunctor on X (? is known as return in Haskell)

...satisfying these laws:

• µ ° Tµ = µ ° µT
• µ ° T? = µ ° ?T = 1 (the identity natural transformation)

With a bit of squinting you might be able to see that both of these definitions are instances of the same abstract concept.

You can do this directly with tar and even better:

tar -N '2014-02-01 18:00:00' -jcvf archive.tar.bz2 files

This instructs tar to compress files newer than 1st of January 2014, 18:00:00.

I found this question looking for solution about how to send post request from java client to Google Endpoints. Above answers, very likely correct, but not work in case of Google Endpoints.

Solution for Google Endpoints.

1. Request body must contains only JSON string, not name=value pair.

2. Content type header must be set to "application/json".

   post("http://localhost:8888/_ah/api/langapi/v1/createLanguage",
                      "{\"language\":\"russian\", \"description\":\"dsfsdfsdfsdfsd\"}");
   
   
   
   public static void post(String url, String json ) throws Exception{
     String charset = "UTF-8"; 
     URLConnection connection = new URL(url).openConnection();
     connection.setDoOutput(true); // Triggers POST.
     connection.setRequestProperty("Accept-Charset", charset);
     connection.setRequestProperty("Content-Type", "application/json;charset=" + charset);
   
     try (OutputStream output = connection.getOutputStream()) {
       output.write(json.getBytes(charset));
     }
   
     InputStream response = connection.getInputStream();
   }
   

   It sure can be done using HttpClient as well.

To make the answer simple here is a program that reads integers from the file and sorting them

f = open("input.txt", 'r')

nums = f.readlines()
nums = [int(i) for i in nums]

After reading each line of the file converting each string to a digit

nums.sort()

Sorting the numbers

f.close()

f = open("input.txt", 'w')
for num in nums:
    f.write("%d\n" %num)

f.close()

Writing them back As easy as that, Hope this helps

OK.I just found out that if we want the FlatList to know the data change outside of the data prop,we need set it to extraData, so I do it like this now:

<FlatList data={...} extraData={this.state} .../>

refer to : https://facebook.github.io/react-native/docs/flatlist#extradata

I faced same issue (VS 2015), but my application is running under 32-bit application pool. So even though machine is 64-bit. I installed 32-bit installation and it works.

I find the answer here.

It's because the server variable local_infile is set to FALSE|0. Refer from the document.

You can verify by executing:

SHOW VARIABLES LIKE 'local_infile';

If you have SUPER privilege you can enable it (without restarting server with a new configuration) by executing:

SET GLOBAL local_infile = 1;

There is a better answer to this problem, though I could just break this down step-by-step.

You will need to fetch and checkout the latest upstream changes like so, e.g.:

git fetch upstream
git checkout upstream/master -b revert/john/foo_and_bar

Taking a look at the commit log, you should find something similar to this:

commit b76a5f1f5d3b323679e466a1a1d5f93c8828b269
Merge: 9271e6e a507888
Author: Tim Tom <[email protected]>
Date:   Mon Apr 29 06:12:38 2013 -0700

    Merge pull request #123 from john/foo_and_bar

    Add foo and bar

commit a507888e9fcc9e08b658c0b25414d1aeb1eef45e
Author: John Doe <[email protected]>

    Add bar

commit 470ee0f407198057d5cb1d6427bb8371eab6157e
Author: John Doe <[email protected]>
Date:   Mon Apr 29 10:29:10 2013 +0000

    Add foo

Now you want to revert the entire pull request with the ability to unrevert later. To do so, you will need to take the ID of the merge commit.

In the above example the merge commit is the top one where it says "Merged pull request #123...".

Do this to revert the both changes ("Add bar" and "Add foo") and you will end up with in one commit reverting the entire pull request which you can unrevert later on and keep the history of changes clean:

git revert -m 1 b76a5f1f5d3b323679e466a1a1d5f93c8828b269

I also have the same problem. Turned out I have the @PropertySource annotation set on the main Application class to read a different base properties file, so the normal "application.properties" is not used anymore.

I had this problem with Blend for Visual Studio 2015. The Toolbox would just not appear anymore. This turns out to be because Blend is not Visual Studio!

(You can edit your code in Blend and build and run it... It certainly seems like Visual Studio, but it isn't. I'm not sure what the purpose of Blend is...)

You can tell you are in Blend if the task bar icon has big "B" in it. To switch from Blend to Visual Studio, go to View-> Edit in Visual Studio.... It will open up another application that looks just like Blend, except the Solution Explorer is on the right instead of the left, and now you have a toolbox...

Java is a compiled programming language, but rather than compile straight to executable machine code, it compiles to an intermediate binary form called JVM byte code. The byte code is then compiled and/or interpreted to run the program.

All the random methods end up calling random.random() so the best way is to call it directly:

[int(1000*random.random()) for i in xrange(10000)]

For example,

• random.randint calls random.randrange.
• random.randrange has a bunch of overhead to check the range before returning istart + istep*int(self.random() * n).

NumPy is much faster still of course.

You want to use:

Collections.<String>emptyList();

If you look at the source for what emptyList does you see that it actually just does a

return (List<T>)EMPTY_LIST;

Take a look at the Python tutorial section 4.7.3 and 4.7.4. It talks about passing tuples as arguments.

I would also consider using named parameters (and passing a dictionary) instead of using a tuple and passing a sequence. I find the use of positional arguments to be a bad practice when the positions are not intuitive or there are multiple parameters.

If you want to do something AFTER the rotation is complete, you can use the UIViewControllerTransitionCoordinator completion handler like this

public override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
    super.viewWillTransition(to: size, with: coordinator)

    // Hook in to the rotation animation completion handler
    coordinator.animate(alongsideTransition: nil) { (_) in
        // Updates to your UI...
        self.tableView.reloadData()
    }
}

What are you developing in? Are you using Apache Tomcat?

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.target=System.out
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyyMMdd HH:mm:ss.SSS} [[%5p] %c{1} [%t]] %m%n

I have a properties like this in a Java app of mine.

$_SERVER['HTTP_REFERER'] is the answer

a = ['a', 'b']
b = ['c', 'd']
arr = [a, b].flatten

This won't remove dups, but

a|b

removes dups.

There is no portable function that allows to check if a key is hit and continue if not. This is always system dependent.

Solution for linux and other posix compliant systems:

Here, for Morgan Mattews's code provide kbhit() functionality in a way compatible with any POSIX compliant system. He uses the trick of desactivating buffering at termios level.

Solution for windows:

For windows, Microsoft offers _kbhit()

Just in case someone is looking to this too. In .net core 3+ most of this is obsolete. The update way is:

public void Configure(
    IApplicationBuilder app,
    IWebHostEnvironment env,
    ILogger<Startup> logger)
{
    if (env.EnvironmentName == Environments.Development)
    {
        // logger.LogInformation("In Development environment");
    }
}

Use tr:first-child to take the first tr:

.category_table tr:first-child td {
    vertical-align: top;
}

If you have nested tables, and you don't want to apply styles to the inner rows, add some child selectors so only the top-level tds in the first top-level tr get the styles:

.category_table > tbody > tr:first-child > td {
    vertical-align: top;
}

Try not to do DOM manipulation by referring the DOM directly, it will have lot of performance issue, also event handling becomes more tricky when we try to access DOM directly, instead use data and directives to manipulate the DOM.

This will give you more control over the manipulation, also you will be able to manage functionalities in the modular format.

in the "Ouput Window". you can usually do CTRL-ALT-O to make it visible. Or through menus using View->Output.

I would suggest static class with static readonly. Please find the code snippet below:

  public static class CachedKeysManager
    {
        public static readonly string DistributorList = "distributorList";
    }

Using Bash syntax,

$(git rev-list --count HEAD)

looks fine for purely linear history. If you also want to sometimes have “numbers” from branches (based off master), consider:

$(git rev-list --count $(git merge-base master HEAD)).$(git rev-list --count ^master HEAD)

When run from a checkout of master, you get simply 1234.0 or the like. When run from a checkout of a branch you will get something like 1234.13, if there have been 13 commits made on that branch. Obviously this is useful only insofar as you are basing at most one branch off a given master revision.

--first-parent could be added to the micro number to suppress some commits arising only from merging other branches, though it is probably unnecessary.

Each tablespace has one or more datafiles that it uses to store data.

The max size of a datafile depends on the block size of the database. I believe that, by default, that leaves with you with a max of 32gb per datafile.

To find out if the actual limit is 32gb, run the following:

select value from v$parameter where name = 'db_block_size';

Compare the result you get with the first column below, and that will indicate what your max datafile size is.

I have Oracle Personal Edition 11g r2 and in a default install it had an 8,192 block size (32gb per data file).

Block Sz   Max Datafile Sz (Gb)   Max DB Sz (Tb)

--------   --------------------   --------------

   2,048                  8,192          524,264

   4,096                 16,384        1,048,528

   8,192                 32,768        2,097,056

  16,384                 65,536        4,194,112

  32,768                131,072        8,388,224

You can run this query to find what datafiles you have, what tablespaces they are associated with, and what you've currrently set the max file size to (which cannot exceed the aforementioned 32gb):

select bytes/1024/1024 as mb_size,
       maxbytes/1024/1024 as maxsize_set,
       x.*
from   dba_data_files x

MAXSIZE_SET is the maximum size you've set the datafile to. Also relevant is whether you've set the AUTOEXTEND option to ON (its name does what it implies).

If your datafile has a low max size or autoextend is not on you could simply run:

alter database datafile 'path_to_your_file\that_file.DBF' autoextend on maxsize unlimited;

However if its size is at/near 32gb an autoextend is on, then yes, you do need another datafile for the tablespace:

alter tablespace system add datafile 'path_to_your_datafiles_folder\name_of_df_you_want.dbf' size 10m autoextend on maxsize unlimited;

Adding to the answer from E_8.
This does not work if you have empty strings.

You can get around this by modifying your select statement in SQL or modifying your query in the SSRS dataset.

 Select distinct phonenumber
from YourTable
where phonenumber <> ''
Order by Phonenumber

Delete the hidden .git folder (that you can locate within your project folder) and again start the process of creating a git repository using git init command.

TL;DR

.col-X-Y means on screen size X and up, stretch this element to fill Y columns.

Bootstrap provides a grid of 12 columns per .row, so Y=3 means width=25%.

xs, sm, md, lg are the sizes for smartphone, tablet, laptop, desktop respectively.

The point of specifying different widths on different screen sizes is to let you make things larger on smaller screens.

Example

<div class="col-lg-6 col-xs-12">

Meaning: 50% width on Desktops, 100% width on Mobile, Tablet, and Laptop.

I am using Debian but this solution should work fine with Ubuntu.
You have to add a line in the neo4j-service script.
Here is what I have done :

nano /etc/init.d/neo4j-service
Add « ulimit –n 40000 » just before the start-stop-daemon line in the do_start section

Note that I am using version 2.0 Enterprise edition. Hope this will help you.

After failing with cleaning the Credentials from the Manager and clearing the VS cache, consider to repair Visual Studio from the Visual Studio Installer (VS2017). I personally found no other solution working.

For such a seemingly simple thing this can be a royal pain in the butt! I found a solution that works beautifully (class="video-close" is obviously particular to this button and optional)

 <a href="javascript:window.open('','_self').close();" class="video-close">Close this window</a>

You can use the DATE(Year;Month;Day) to make operations on date:

Examples:

=DATE(2013;3;8 + 30) give the result...  7 april 2013 !
=DATE(2013;3 + 15; 8) give the result... 8 june 2014 !

It's very surprising but it works...

I prefer to use both plural (/resources) and singular (/resource/{id}) because I think that it more clearly separates the logic between working on the collection of resources and working on a single resource.

As an important side-effect of this, it can also help to prevent somebody using the API wrongly. For example, consider the case where a user wrongly tries to get a resource by specifying the Id as a parameter like this:

GET /resources?Id=123

In this case, where we use the plural version, the server will most likely ignore the Id parameter and return the list of all resources. If the user is not careful, he will think that the call was successful and use the first resource in the list.

On the other hand, when using the singular form:

GET /resource?Id=123

the server will most likely return an error because the Id is not specified in the right way, and the user will have to realize that something is wrong.

Yes. Now Google wants an API key to authenticate users to access their APIs`.

You can get the API key from the following link. Go through the link and you need to enter a project and so on. But it is easy. Hassle free.

https://developers.google.com/maps/documentation/javascript/get-api-key

Once you get the API key change the previous

<script src="https://maps.googleapis.com/maps/api/js"></script>

to

<script src="https://maps.googleapis.com/maps/api/js?libraries=places&key=your_api_key_here"></script>

Now your google map is in action. In case if you are wondering to get the longitude and latitude to input to Maps. Just pin the location you want and check the URL of the browser. You can see longitude and latitude values there. Just copy those values and paste it as follows.

new google.maps.LatLng(longitude ,latitude )

How about something like:

\documentclass{article}

\usepackage{amssymb,amsmath}

\begin{document}

\begin{equation}\label{A_Label}
  \begin{split}
    w^T x_i + b \geqslant 1-\xi_i \text{ if } y_i &= 1, \\
    w^T x_i + b \leqslant -1+\xi_i \text{ if } y_i &= -1
  \end{split}
\end{equation}

\end{document}

which produces:

If you are trying to clear out a receive buffer for something that receives strings I have found the best way is to use memset as described above. The reason is that no matter how big the next received string is (limited to sizeof buffer of course), it will automatically be an asciiz string if written into a buffer that has been pre-zeroed.

Replace a string :

$str = str_replace("\n", '', $str);

u using also like, (%n, %t, All Special characters, numbers, char,. etc)

which means any thing u can replace in a string.

A merge conflict occurs when two branches you're trying to merge both changed the same part of the same file. You can generate a list of conflicts with git status.

When the conflicted line is encountered, Git will edit the content of the affected files with visual indicators that mark both sides of the conflicting content.

<<<<<<< HEAD
conflicted text from HEAD
=======
conflicted text from merging_branch
>>>>>>> merging_branch

When you fix your conflicted files and you are ready to merge, all you have to do is run git add and git commit to generate the merge commit. Once the commit was made ,git push the changes to the branch.

Reference article: Git merge.

Please Try this

func applyShadowOnView(_ view: UIView) {
    view.layer.cornerRadius = 8
    view.layer.shadowColor = UIColor.darkGray.cgColor
    view.layer.shadowOpacity = 1
    view.layer.shadowOffset = .zero
    view.layer.shadowRadius = 5
}

Default implementations of the classloader cannot load from a jar-within-a-jar: in order to do so, the entire 'sub-jar' would have to be loaded into memory, which defeats the random-access benefits of the jar format (reference pending - I'll make an edit once I find the documentation supporting this).

I recommend using a program such as JarSplice to bundle everything for you into one clean executable jar.

Edit: Couldn't find the source reference, but here's an un-resolved RFE off the Sun website describing this exact 'problem': http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4648386

Also, you could 'test' that your program works by placing the library jar files in a \lib sub-directory of your classes directory, then running from the command line. In other words, with the following directory structure:

classes/org/sai/com/DerbyDemo.class
classes/org/sai/com/OtherClassFiles.class
classes/lib/derby.jar
classes/lib/derbyclient.jar

From the command line, navigate to the above-mentioned 'classes' directory, and type:

java -cp .:lib/* org.sai.com.DerbyDemo

Yes, you could.

• A null pointer is converted to false implicitly
• a non-null pointer is converted to true.

This is part of the C++ standard conversion, which falls in Boolean conversion clause:

§ 4.12 Boolean conversions

A prvalue of arithmetic, unscoped enumeration, pointer, or pointer to member type can be converted to a prvalue of type bool. A zero value, null pointer value, or null member pointer value is converted to false; any other value is converted to true. A prvalue of type std::nullptr_t can be converted to a prvalue of type bool; the resulting value is false.

Copy past following code in your .htaccess

RewriteEngine on
Options -Indexes
RewriteCond $1 !^(index\.php|assets|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

If you want to add multiple items, you have to use the spread operator

a = [1,2]
b = [3,4,5,6]
a.push(...b)

The output will be

a = [1,2,3,4,5,6]

Here is the solution that uses compile-time calculation:

constexpr auto* getFileName(const char* const path)
{
    const auto* startPosition = path;
    for (const auto* currentCharacter = path;*currentCharacter != '\0'; ++currentCharacter)
    {
        if (*currentCharacter == '\\' || *currentCharacter == '/')
        {
            startPosition = currentCharacter;
        }
    }

    if (startPosition != path)
    {
        ++startPosition;
    }

    return startPosition;
}

std::cout << getFileName(__FILE__);

Make sure that you also include smtp class which comes with phpmailer:

// for mailing
require("phpmailer/class.phpmailer.php");
require("phpmailer/class.smtp.php");

Runas.exe won't work here. You can use VBScript to invoke the "Run as Administrator" shell verb. The Elevation Powertoys contain a batchfile that allows you to invoke an elevated command:

elevatecmd.exe

http://blogs.technet.com/b/elevationpowertoys/

Use String.Format:

string title1 = "Sample Title One";
string element1 = "Element One";
string format = "{0,-20} {1,-10}";

string result = string.Format(format, title1, element1);
//or you can print to Console directly with
//Console.WriteLine(format, title1, element1);

In the format {0,-20} means the first argument has a fixed length 20, and the negative sign guarantees the string is printed from left to right.

Provided that the remote repository is origin, and that you're interested in master:

git fetch origin
git reset --hard origin/master

This tells it to fetch the commits from the remote repository, and position your working copy to the tip of its master branch.

All your local commits not common to the remote will be gone.

You can use LEN in combination with SUBSTRING:

SELECT SUBSTRING(myColumn, 7, LEN(myColumn)) from myTable

Another solution would be to write a wrapper that store the array like this:

localStorage.setItem('names_length', names.length);
localStorage.setItem('names_0', names[0]);
localStorage.setItem('names_1', names[1]);
localStorage.setItem('names_' + n, names[n]);

Removes the overhead of converting to JSON, but would be annoying if you need to remove elements, as you would have to re-index the array :)

Simply use:

String variable="StackOverflow";
textView.setText(Html.fromHtml("<b>Hello : </b>"+ variable));

Q. When is the "with grant option" required ?

A. when you have a view executed from a third schema.

Example: schema DSDSW has a view called view_name

a) that view selects from a table in another schema  (FDR.balance)
b) a third shema  X_WORK  tries to select  from that view

Typical grants: grant select on dsdw.view_name to dsdw_select_role; grant dsdw_select_role to fdr;

But: fdr gets select count(*) from dsdw.view_name; ERROR at line 1: ORA-01031: insufficient privileges

issue the grant:

grant select on fdr.balance to dsdw with grant option;

now fdr: select count(*) from dsdw.view_name; 5 rows

How do I check a variable if it's null or undefined...

Is the variable null:

if (a === null)
// or
if (a == null) // but see note below

...but note the latter will also be true if a is undefined.

Is it undefined:

if (typeof a === "undefined")
// or
if (a === undefined)
// or
if (a == undefined) // but see note below

...but again, note that the last one is vague; it will also be true if a is null.

Now, despite the above, the usual way to check for those is to use the fact that they're falsey:

if (!a) {
    // `a` is falsey, which includes `undefined` and `null`
    // (and `""`, and `0`, and `NaN`, and [of course] `false`)
}

This is defined by ToBoolean in the spec.

...and what is the difference between the null and undefined?

They're both values usually used to indicate the absence of something. undefined is the more generic one, used as the default value of variables until they're assigned some other value, as the value of function arguments that weren't provided when the function was called, and as the value you get when you ask an object for a property it doesn't have. But it can also be explicitly used in all of those situations. (There's a difference between an object not having a property, and having the property with the value undefined; there's a difference between calling a function with the value undefined for an argument, and leaving that argument off entirely.)

null is slightly more specific than undefined: It's a blank object reference. JavaScript is loosely typed, of course, but not all of the things JavaScript interacts with are loosely typed. If an API like the DOM in browsers needs an object reference that's blank, we use null, not undefined. And similarly, the DOM's getElementById operation returns an object reference — either a valid one (if it found the DOM element), or null (if it didn't).

Interestingly (or not), they're their own types. Which is to say, null is the only value in the Null type, and undefined is the only value in the Undefined type.

What is the difference between "==" and "==="

The only difference between them is that == will do type coercion to try to get the values to match, and === won't. So for instance "1" == 1 is true, because "1" coerces to 1. But "1" === 1 is false, because the types don't match. ("1" !== 1 is true.) The first (real) step of === is "Are the types of the operands the same?" and if the answer is "no", the result is false. If the types are the same, it does exactly what == does.

Type coercion uses quite complex rules and can have surprising results (for instance, "" == 0 is true).

More in the spec:

• Abstract Equality Comparison (==, also called "loose" equality)
• Strict Equality Comparison (===)

An alternative solution is to use a wrapper for the String, for instances this:

public class StringResponse {
    private String response;
    public StringResponse(String response) {
        this.response = response;
    }
    public String getResponse() {
        return response;
    }
}

Then return this in your controller's methods:

ResponseEntity<StringResponse>

Maybe you have a hardware problem.

I had the same problem on my old system (AMD 1800 MHz CPU ,1GB RAM ,Windows 7 Ultimate) ,until I changed the 2x 512 MB RAM to 2x 1GB RAM. Haven't had any problems since. Also other (minor) problems disappeared. Guess those two 512 MB modules didn't like each other that much ,because 2x 512 MB + 1GB or 1x 512 MB + 2x 1GB didn't work properly either.

bool result = Int32.TryParse(someString, out someNumeric)

This method will try to convert someString into someNumeric, and return a result depends if the conversion is successful, true if conversion is successful and false if conversion failed. Take note that this method will not throw exception if the conversion failed like how Int32.Parse method did and instead it returns zero for someNumeric.

How to convert string to integer in C#

It doesn't matter if the random_state is 0 or 1 or any other integer. What matters is that it should be set the same value, if you want to validate your processing over multiple runs of the code. By the way I have seen random_state=42 used in many official examples of scikit as well as elsewhere also.

random_state as the name suggests, is used for initializing the internal random number generator, which will decide the splitting of data into train and test indices in your case. In the documentation, it is stated that:

If random_state is None or np.random, then a randomly-initialized RandomState object is returned.

If random_state is an integer, then it is used to seed a new RandomState object.

If random_state is a RandomState object, then it is passed through.

This is to check and validate the data when running the code multiple times. Setting random_state a fixed value will guarantee that same sequence of random numbers are generated each time you run the code. And unless there is some other randomness present in the process, the results produced will be same as always. This helps in verifying the output.

You specified both jQuery and Javascript in the tags so here's both approaches.

jQuery

var selector = '.nav li';

$(selector).on('click', function(){
    $(selector).removeClass('active');
    $(this).addClass('active');
});

Fiddle: http://jsfiddle.net/bvf9u/

Pure Javascript:

var selector, elems, makeActive;

selector = '.nav li';

elems = document.querySelectorAll(selector);

makeActive = function () {
    for (var i = 0; i < elems.length; i++)
        elems[i].classList.remove('active');

    this.classList.add('active');
};

for (var i = 0; i < elems.length; i++)
    elems[i].addEventListener('mousedown', makeActive);

Fiddle: http://jsfiddle.net/rn3nc/1

jQuery with event delegation:

Please note that in approach 1, the handler is directly bound to that element. If you're expecting the DOM to update and new lis to be injected, it's better to use event delegation and delegate to the next element that will remain static, in this case the .nav:

$('.nav').on('click', 'li', function(){
    $('.nav li').removeClass('active');
    $(this).addClass('active');
});

Fiddle: http://jsfiddle.net/bvf9u/1/

The subtle difference is that the handler is bound to the .nav now, so when you click the li the event bubbles up the DOM to the .nav which invokes the handler if the element clicked matches your selector argument. This means new elements won't need a new handler bound to them, because it's already bound to an ancestor.

It's really quite interesting. Read more about it here: http://api.jquery.com/on/

String url = "https://www.murait.com/";
if (url.startsWith("https://") || url.startsWith("http://")) {
    Uri uri = Uri.parse(url);
    Intent intent = new Intent(Intent.ACTION_VIEW, uri);
    startActivity(intent);
}else{
    Toast.makeText(mContext, "Invalid Url", Toast.LENGTH_SHORT).show();
}

You have to check that the URL is valid or not. If URL is invalid application may crash so that you have to check URL is valid or not by this method.

use the builtin: (no need for tkinter)

s = input('->>')

I have faced issue like my main page index.jsp contains the below line but eventhough rendering was not proper in IE. Found the issue and I have added the code in all the files which I included in index.jsp. Hurray! it worked.

perldoc perlvar does not seem to suggest any such variable.

The value of the length property must be greater than or equal to name atribute length, else throwing an error.

Works

@Column(name = "typ e", length = 4, unique = true)
private String type;

Not works, type.length: 4 != length property: 3

@Column(name = "type", length = 3, unique = true)
private String type;

When you post that data, it is stored as an array in $_POST.

You could optionally do something like:

<input name="arrayname[item1]">
<input name="arrayname[item2]">
<input name="arrayname[item3]">

Then:

$item1 = $_POST['arrayname']['item1'];
$item2 = $_POST['arrayname']['item2'];
$item3 = $_POST['arrayname']['item3'];

But I fail to see the point.

Want HEAD detached mode?

If you wish to rollback X time to a certain commit with a DETACHED HEAD (meaning you can't mess up anything), then by all means, use the following:

(replace X with how many commits you wish to go back)

git checkout HEAD~X

I.E. to go back one commit:

git checkout HEAD~1

I also faced the same issue...try to do this...this worked for me

Install cron on Linux/Unix:

Use cron on Linux/Unix

crontab -e

The big difference is, substr() is a deprecated method that can still be used, but should be used with caution because they are expected to be removed entirely sometime in the future. You should work to remove their use from your code. And the substring() method succeeded and specified the former one.

First of all, you should be using json.loads, not json.dumps. loads converts JSON source text to a Python value, while dumps goes the other way.

After you fix that, based on the JSON snippet at the top of your question, readable_json will be a list, and so readable_json['firstName'] is meaningless. The correct way to get the 'firstName' field of every element of a list is to eliminate the playerstuff = readable_json['firstName'] line and change for i in playerstuff: to for i in readable_json:.

Try this if you wan't to use SSL certificates:

import subprocess

try:
    # Set scp and ssh data.
    connUser = 'john'
    connHost = 'my.host.com'
    connPath = '/home/john/'
    connPrivateKey = '/home/user/myKey.pem'

    # Use scp to send file from local to host.
    scp = subprocess.Popen(['scp', '-i', connPrivateKey, 'myFile.txt', '{}@{}:{}'.format(connUser, connHost, connPath)])

except CalledProcessError:
    print('ERROR: Connection to host failed!')

This does the trick, and works for any select.

$('#baba').val($(this).find('option:first').val());

var streetaddress= addy.substr(0, addy.indexOf(',')); 

While it's not the best place for definitive information on what each method does (mozilla developer network is better for that) w3schools.com is good for introducing you to syntax.

I believe I ran exactly into the same issue. After countless hours of fighting with the JSON, the JavaScript and the Server, I found the culprit: In my case I had a Date object in the DTO, this Date object was converted to a String so we could show it in the view with the format: HH:mm.

When JSON information was being sent back, this Date String object had to be converted back into a full Date Object, therefore we also need a method to set it in the DTO. The big BUT is you cannot have 2 methods with the same name (Overload) in the DTO even if they have different type of parameter (String vs Date) because this will give you also the 415 Unsupported Media type error.

This was my controller method

  @RequestMapping(value = "/alarmdownload/update", produces = "application/json", method = RequestMethod.POST)
  public @ResponseBody
  StatusResponse update(@RequestBody AlarmDownloadDTO[] rowList) {
    System.out.println("hola");
    return new StatusResponse();
  }

This was my DTO example (id get/set and preAlarm get Methods are not included for code shortness):

@JsonIgnoreProperties(ignoreUnknown = true)
public class AlarmDownloadDTO implements Serializable {

  private static final SimpleDateFormat formatHHmm = new SimpleDateFormat("HH:mm");

  private String id;
  private Date preAlarm;

  public void setPreAlarm(Date date) { 
    this.preAlarm == date;
  }
  public void setPreAlarm(String date) {    
    try {
      this.preAlarm = formatHHmm.parse(date);
    } catch (ParseException e) {
      this.preAlarm = null;
    } catch (NullPointerException e){
      this.preAlarm = null;
    }
  }
}

To make everything work you need to remove the method with Date type parameter. This error is very frustrating. Hope this can save someone hours of debugging.

As of January 2nd, 2021, Google posted these two keys for testing in this article.

I'd like to run automated tests with reCAPTCHA. What should I do? For reCAPTCHA v3, create a separate key for testing environments. Scores may not be accurate as reCAPTCHA v3 relies on seeing real traffic.

For reCAPTCHA v2, use the following test keys. You will always get No CAPTCHA and all verification requests will pass.

Site key: 6LeIxAcTAAAAAJcZVRqyHh71UMIEGNQ_MXjiZKhI
Secret key: 6LeIxAcTAAAAAGG-vFI1TnRWxMZNFuojJ4WifJWe

The reCAPTCHA widget will show a warning message to ensure it's not used for production traffic.

The generated emails went into spam the first time I used the keys.

in my opinion the easiest way would be somthing like this:

<?php>
echo '<a href="link.php?submit='.$value.'">Submit</a>';

A and B reference the same object, so A.a and B.a reference the same property of the same object.

Edit

Here's a "copy" function that may do the job, it can do both shallow and deep clones. Note the caveats. It copies all enumerable properties of an object (not inherited properties), including those with falsey values (I don't understand why other approaches ignore them), it also doesn't copy non–existent properties of sparse arrays.

There is no general copy or clone function because there are many different ideas on what a copy or clone should do in every case. Most rule out host objects, or anything other than Objects or Arrays. This one also copies primitives. What should happen with functions?

So have a look at the following, it's a slightly different approach to others.

/* Only works for native objects, host objects are not
** included. Copies Objects, Arrays, Functions and primitives.
** Any other type of object (Number, String, etc.) will likely give 
** unexpected results, e.g. copy(new Number(5)) ==> 0 since the value
** is stored in a non-enumerable property.
**
** Expects that objects have a properly set *constructor* property.
*/
function copy(source, deep) {
   var o, prop, type;

  if (typeof source != 'object' || source === null) {
    // What do to with functions, throw an error?
    o = source;
    return o;
  }

  o = new source.constructor();

  for (prop in source) {

    if (source.hasOwnProperty(prop)) {
      type = typeof source[prop];

      if (deep && type == 'object' && source[prop] !== null) {
        o[prop] = copy(source[prop]);

      } else {
        o[prop] = source[prop];
      }
    }
  }
  return o;
}

It is possible.

When you use Return inside a procedure, the control is transferred to the calling program which calls the procedure. It is like an exit in loops.

It won't return any value.

You could use the FirstOrDefault() extension, which is available for IEnumerable<T>. By returning false from the predicate, it will be run for each element but will not care that it doesn't actually find a match. This will avoid the ToList() overhead.

IEnumerable<Item> items = GetItems();
items.FirstOrDefault(i => { i.DoStuff(); return false; });

UPDATE Table1 SET col1= col2 FROM (SELECT col2, col3 FROM Table2) as newTbl WHERE col4= col3

Here col4 & col1 are in Table1. col2 & col3 are in Table2
I Am trying to update each col1 where col4 = col3 different value for each row

Another simple way to exclude the auto configuration classes,

Add below similar configuration to your application.yml file,

---
spring:
  profiles: test
  autoconfigure.exclude: org.springframework.boot.autoconfigure.session.SessionAutoConfiguration

Use java assist Java library for manipulating the Java bytecode (.class file) of an application.

-> Spring , Hibernate , EJB using this for proxy implementation

-> we can bytecode manipulation to do some program analysis

-> we can use Javassist to implement a transparent cache for method return values, by intercepting all method invocations and only delegating to the super implementation on the first invocation.

If you are building your application using Spring Framework I would suggest using javax.validation.constraints.NotNull comming from Beans Validation packaged in following dependency:

    <dependency>
        <groupId>javax.validation</groupId>
        <artifactId>validation-api</artifactId>
        <version>1.1.0.Final</version>
    </dependency>

The main advantage of this annotation is that Spring provides support for both method parameters and class fields annotated with javax.validation.constraints.NotNull. All you need to do to enable support is:

1. supply the api jar for beans validation and jar with implementation of validator of jsr-303/jsr-349 annotations (which comes with Hibernate Validator 5.x dependency):

   <dependency>
       <groupId>javax.validation</groupId>
       <artifactId>validation-api</artifactId>
       <version>1.1.0.Final</version>
   </dependency>
   <dependency>
       <groupId>org.hibernate</groupId>
       <artifactId>hibernate-validator</artifactId>
       <version>5.4.1.Final</version>
   </dependency>
   

2. provide MethodValidationPostProcessor to spring's context

     @Configuration
     @ValidationConfig
     public class ValidationConfig implements MyService {
   
           @Bean
           public MethodValidationPostProcessor providePostProcessor() {
                 return new MethodValidationPostProcessor()
           }
     }
   

3. finally you annotate your classes with Spring's org.springframework.validation.annotation.Validated and validation will be automatically handled by Spring.

Example:

@Service
@Validated
public class MyServiceImpl implements MyService {

  @Override
  public Something doSomething(@NotNull String myParameter) {
        // No need to do something like assert myParameter != null  
  }
}

When you try calling method doSomething and pass null as the parameter value, spring (by means of HibernateValidator) will throw ConstraintViolationException. No need for manuall work here.

You can also validate return values.

Another important benefit of javax.validation.constraints.NotNull comming for Beans Validation Framework is that at the moment it is still developed and new features are planned for new version 2.0.

What about @Nullable? There is nothing like that in Beans Validation 1.1. Well, I could arguee that if you decide to use @NotNull than everything which is NOT annotated with @NonNull is effectively "nullable", so the @Nullable annotation is useless.

Try this instead to only select the visible elements under the tbody:

$('tbody :visible').highlight(myArray[i]);

In addition to the above answers, I would say for columns having no single word name, you may use:-

df[df['Product ID'].str.contains("foo") == True]

Hope this helps.

You can list all unreachable commits by writing this command in terminal -

git fsck --unreachable

Check unreachable commit hash -

git show hash

Finally apply if you find the stashed item -

git stash apply hash

You can add extra data with form data

use serializeArray and add the additional data:

var data = $('#myForm').serializeArray();
    data.push({name: 'tienn2t', value: 'love'});
    $.ajax({
      type: "POST",
      url: "your url.php",
      data: data,
      dataType: "json",
      success: function(data) {
          //var obj = jQuery.parseJSON(data); if the dataType is not     specified as json uncomment this
        // do what ever you want with the server response
     },
    error: function() {
        alert('error handing here');
    }
});

What other answers missed, is that the path given to the function could actually be a directory. Following function makes sure, that the path is really a file.

func fileExists(filename string) bool {
    info, err := os.Stat(filename)
    if os.IsNotExist(err) {
        return false
    }
    return !info.IsDir()
}

Another thing to point out: This code could still lead to a race condition, where another thread or process deletes or creates the specified file, while the fileExists function is running.

If you're worried about this, use a lock in your threads, serialize the access to this function or use an inter-process semaphore if multiple applications are involved. If other applications are involved, outside of your control, you're out of luck, I guess.

The purpose of interfaces is abstraction, or decoupling from implementation.

If you introduce an abstraction in your program, you don't care about the possible implementations. You are interested in what it can do and not how, and you use an interface to express this in Java.

this error usually shows if the name of your struct is different from the initialization of your struct in the code, so normally, c will find the name of the struct you put and if the original struct is not found, this would usually appear, or if you point a pointer pointed into that pointer, the error will show up.

Another way brackets and parentheses differ is that square brackets can describe a list comprehension, e.g. [x for x in y]

Whereas the corresponding parenthetic syntax specifies a tuple generator: (x for x in y)

You can get a tuple comprehension using: tuple(x for x in y)

See: Why is there no tuple comprehension in Python?

Having had a similar itch to scratch (altough only for some files of a given repository) this script proved to be really helpful: git-import

The short version is that it creates patch files of the given file or directory ($object) from the existing repository:

cd old_repo
git format-patch --thread -o "$temp" --root -- "$object"

which then get applied to a new repository:

cd new_repo
git am "$temp"/*.patch 

For details please look up:

• the documented source
• git format-patch
• git am

I noticed that pure exec bash command will preserve the environment variables, so you need to use exec -c bash to run bash in an empty environment.

For example, you login a bash, and export A=1, if you exec bash, the A == 1.

If you exec -cl bash, A is empty.

I think this is the best way to do your job.

I'm not sure about more efficient in terms of big-O but certainly using the unshift method is more concise:

var a = [1, 2, 3, 4];
a.unshift(0);
a; // => [0, 1, 2, 3, 4]

[Edit]

This jsPerf benchmark shows that unshift is decently faster in at least a couple of browsers, regardless of possibly different big-O performance if you are ok with modifying the array in-place. If you really can't mutate the original array then you would do something like the below snippet, which doesn't seem to be appreciably faster than your solution:

a.slice().unshift(0); // Use "slice" to avoid mutating "a".

[Edit 2]

For completeness, the following function can be used instead of OP's example prependArray(...) to take advantage of the Array unshift(...) method:

function prepend(value, array) {
  var newArray = array.slice();
  newArray.unshift(value);
  return newArray;
}

var x = [1, 2, 3];
var y = prepend(0, x);
y; // => [0, 1, 2, 3];
x; // => [1, 2, 3];

Here's the calling order:

1. app.config()
2. app.run()
3. directive's compile functions (if they are found in the dom)
4. app.controller()
5. directive's link functions (again, if found)

Here's a simple demo where you can watch each one executing (and experiment if you'd like).

From Angular's module docs:

Run blocks - get executed after the injector is created and are used to kickstart the application. Only instances and constants can be injected into run blocks. This is to prevent further system configuration during application run time.

Run blocks are the closest thing in Angular to the main method. A run block is the code which needs to run to kickstart the application. It is executed after all of the services have been configured and the injector has been created. Run blocks typically contain code which is hard to unit-test, and for this reason should be declared in isolated modules, so that they can be ignored in the unit-tests.

One situation where run blocks are used is during authentications.

$('.my-link').click(function(e) { e.preventDefault(); }); 

You could use:

$('.my-link').click(function(e) { return false; }); 

But I don't like to use this myself as it is more cryptic, even though it is used extensively throughout much jQuery code.

I use the following code:

$("#myImage").attr("src","img/spinner.gif");

var img = new Image();
$(img).load(function() {
    $("#myImage").attr("src",img.src);
});
img.src = "http://example.com/imageToPreload.jpg";

Done.

Daniel Imms answer is excellent in regards to applying your CSS rotation to an inner element. However, it is possible to accomplish the end goal in a way that does not require JavaScript and works with longer strings of text.

Typically the whole reason to have vertical text in the first table column is to fit a long line of text in a short horizontal space and to go alongside tall rows of content (as in your example) or multiple rows of content (which I'll use in this example).

By using the ".rotate" class on the parent TD tag, we can not only rotate the inner DIV, but we can also set a few CSS properties on the parent TD tag that will force all of the text to stay on one line and keep the width to 1.5em. Then we can use some negative margins on the inner DIV to make sure that it centers nicely.

One thing to keep in mind with this solution is that it does not work well if the height of the row (or spanned rows) is shorter than the vertical text in the first column. It works best if you're spanning multiple rows or you have a lot of content creating tall rows.

Have fun playing around with this on jsFiddle.

In the event that anyone would be interested. Here's a quick shell script that will remove all local branches that aren't tracked remotely. A word of caution: This will get rid of any branch that isn't tracked remotely regardless of whether it was merged or not.

Save it in a file called git-rm-ntb (call it whatever) on PATH and run:

git-rm-ntb <remote1:optional> <remote2:optional> ...

clean()

  REMOTES="$@";
  if [ -z "$REMOTES" ]; then

There are currently three distinct events which may or may not be triggered when the client devices moves. Two of them are focused around orientation and the last on motion:

• ondeviceorientation is known to work on the desktop version of Chrome, and most Apple laptops seems to have the hardware required for this to work. It also works on Mobile Safari on the iPhone 4 with iOS 4.2. In the event handler function, you can access alpha, beta, gamma values on the event data supplied as the only argument to the function.

• onmozorientation is supported on Firefox 3.6 and newer. Again, this is known to work on most Apple laptops, but might work on Windows or Linux machines with accelerometer as well. In the event handler function, look for x, y, z fields on the event data supplied as first argument.

• ondevicemotion is known to work on iPhone 3GS + 4 and iPad (both with iOS 4.2), and provides data related to the current acceleration of the client device. The event data passed to the handler function has acceleration and accelerationIncludingGravity, which both have three fields for each axis: x, y, z

The "earthquake detecting" sample website uses a series of if statements to figure out which event to attach to (in a somewhat prioritized order) and passes the data received to a common tilt function:

if (window.DeviceOrientationEvent) {
    window.addEventListener("deviceorientation", function () {
        tilt([event.beta, event.gamma]);
    }, true);
} else if (window.DeviceMotionEvent) {
    window.addEventListener('devicemotion', function () {
        tilt([event.acceleration.x * 2, event.acceleration.y * 2]);
    }, true);
} else {
    window.addEventListener("MozOrientation", function () {
        tilt([orientation.x * 50, orientation.y * 50]);
    }, true);
}

The constant factors 2 and 50 are used to "align" the readings from the two latter events with those from the first, but these are by no means precise representations. For this simple "toy" project it works just fine, but if you need to use the data for something slightly more serious, you will have to get familiar with the units of the values provided in the different events and treat them with respect :)

I think it can be simplified into:

grep sysa /etc/passwd || {
    echo "ERROR - The user sysa could not be looked up"
    exit 2
}

or in a single command line

$ grep sysa /etc/passwd || { echo "ERROR - The user sysa could not be looked up"; exit 2; }

I've had issues with using SELECT last_insert_rowid() in a multithreaded environment. If another thread inserts into another table that has an autoinc, last_insert_rowid will return the autoinc value from the new table.

Here's where they state that in the doco:

If a separate thread performs a new INSERT on the same database connection while the sqlite3_last_insert_rowid() function is running and thus changes the last insert rowid, then the value returned by sqlite3_last_insert_rowid() is unpredictable and might not equal either the old or the new last insert rowid.

That's from sqlite.org doco

Just for completeness:

There is another solution, I would recommend: subtree merging.

In contrast to submodules, it's easier to maintain. You would create each repository the normal way. While in your main repository, you want to merge the master (or any other branch) of another repository in a directory of your main directory.

$ git remote add -f OtherRepository /path/to/that/repo
$ git merge -s ours --no-commit OtherRepository/master
$ git read-tree --prefix=AnyDirectoryToPutItIn/ -u OtherRepository/master
$ git commit -m "Merge OtherRepository project as our subdirectory"`

Then, in order to pull the other repository into your directory (to update it), use the subtree merge strategy:

$ git pull -s subtree OtherRepository master

I'm using this method for years now, it works :-)

More about this way including comparing it with sub modules may be found in this git howto doc.

You can have a table variable as a return type and then update or insert on a table based on that output. In other words, you can set the variable output as the original table, make the modifications and then do an insert to the original table from function output. It is a little hack but if you insert the @output_table from the original table and then say for example: Insert into my_table select * from my_function

then you can achieve the result.

I have an additional <category>-tag, don't know if that makes any difference.

<receiver android:name="BootIntentReceiver">  
        <intent-filter>  
            <action android:name="android.intent.action.BOOT_COMPLETED" />  
            <category android:name="android.intent.category.HOME" />  
        </intent-filter>  
</receiver>

Have you tried ommiting the if-clause "android.intent.action.BOOT_COMPLETED".equals(intent.getAction(), as the receiver probably only receives that intent anyway?

Short Answer:

I did it. I wrote a function for dynamic usage for all the little people out there...

Working example which displays on the page

Working example logging to the console

Long Answer:

...Still did it.

It took me awhile to do it, since a psuedo element is not really on the page. While some of the answers above work in SOME scenarios, they ALL fail to be both dynamic and work in a scenario in which an element is both unexpected in size and position(such as absolute positioned elements overlaying a portion of the parent element). Mine does not.

Usage:

//some element selector and a click event...plain js works here too
$("div").click(function() {
    //returns an object {before: true/false, after: true/false}
    psuedoClick(this);

    //returns true/false
    psuedoClick(this).before;

    //returns true/false
    psuedoClick(this).after;

});

How it works:

It grabs the height, width, top, and left positions(based on the position away from the edge of the window) of the parent element and grabs the height, width, top, and left positions(based on the edge of the parent container) and compares those values to determine where the psuedo element is on the screen.

It then compares where the mouse is. As long as the mouse is in the newly created variable range then it returns true.

Note:

It is wise to make the parent element RELATIVE positioned. If you have an absolute positioned psuedo element, this function will only work if it is positioned based on the parent's dimensions(so the parent has to be relative...maybe sticky or fixed would work too....I dont know).

Code:

function psuedoClick(parentElem) {

    var beforeClicked,
      afterClicked;

  var parentLeft = parseInt(parentElem.getBoundingClientRect().left, 10),
      parentTop = parseInt(parentElem.getBoundingClientRect().top, 10);

  var parentWidth = parseInt(window.getComputedStyle(parentElem).width, 10),
      parentHeight = parseInt(window.getComputedStyle(parentElem).height, 10);

  var before = window.getComputedStyle(parentElem, ':before');

  var beforeStart = parentLeft + (parseInt(before.getPropertyValue("left"), 10)),
      beforeEnd = beforeStart + parseInt(before.width, 10);

  var beforeYStart = parentTop + (parseInt(before.getPropertyValue("top"), 10)),
      beforeYEnd = beforeYStart + parseInt(before.height, 10);

  var after = window.getComputedStyle(parentElem, ':after');

  var afterStart = parentLeft + (parseInt(after.getPropertyValue("left"), 10)),
      afterEnd = afterStart + parseInt(after.width, 10);

  var afterYStart = parentTop + (parseInt(after.getPropertyValue("top"), 10)),
      afterYEnd = afterYStart + parseInt(after.height, 10);

  var mouseX = event.clientX,
      mouseY = event.clientY;

  beforeClicked = (mouseX >= beforeStart && mouseX <= beforeEnd && mouseY >= beforeYStart && mouseY <= beforeYEnd ? true : false);

  afterClicked = (mouseX >= afterStart && mouseX <= afterEnd && mouseY >= afterYStart && mouseY <= afterYEnd ? true : false);

  return {
    "before" : beforeClicked,
    "after"  : afterClicked

  };      

}

I dont know....it looks like ie is dumb and likes to return auto as a computed value sometimes. IT SEEMS TO WORK WELL IN ALL BROWSERS IF DIMENSIONS ARE SET IN CSS. So...set your height and width on your psuedo elements and only move them with top and left. I recommend using it on things that you are okay with it not working on. Like an animation or something. Chrome works...as usual.

Lets see, numeric (3,2). That means you have 3 places for data and two of them are to the right of the decimal leaving only one to the left of the decimal. 15 has two places to the left of the decimal. BTW if you might have 100 as a value I'd increase that to numeric (5, 2)

I Avoided forceUpdate by doing following

WRONG WAY : do not use index as key

this.state.rows.map((item, index) =>
   <MyComponent cell={item} key={index} />
)

CORRECT WAY : Use data id as key, it can be some guid etc

this.state.rows.map((item) =>
   <MyComponent item={item} key={item.id} />
)

so by doing such code improvement your component will be UNIQUE and render naturally

alternatively you can do

iter(data).next()['f'] = var

Always prefer to use the language features over some additional tools like preprocessor.

ES.31: Don't use macros for constants or "functions"

Macros are a major source of bugs. Macros don't obey the usual scope and type rules. Macros don't obey the usual rules for argument passing. Macros ensure that the human reader sees something different from what the compiler sees. Macros complicate tool building.

I had the same problem. In which i have to remove white background from jpg/png image format using ImageMagick.

What worked for me was:

1) Convert image format to png: convert input.jpg input.png

2) convert input.png -fuzz 2% -transparent white output.png

from within the git bash shell type:

>cd /bin
>ls -l

You will then see a long listing of all the unix-like commands available. There are lots of goodies in there.

Example : we want to represent an 2D array of SIZE_X and SIZE_Y size. That means that we will have MAXY consecutive rows of MAXX size. Hence the set function is

void set_array( int x, int y, int val ) { array[ x * SIZE_Y + y ] = val; }

The get would be:

int get_array( int x, int y ) { return array[ x * SIZE_Y + y ]; }

Try this->

EditText text = (EditText) findViewById(R.id.text_input);

Editable name = text.getText();

Editable is the return data type of getText() method it will handle both string and integer values

This is how I do this with JQuery...

using the jquery-watermark plugin (http://code.google.com/p/jquery-watermark/)

$('#inputId').watermark('Please select a name');

works like a charm!!

There is some good documentation at that google code site.

Hope this helps!

How I load Icons: Using Visual Studio 2010: Go to the project properties, click Add Resource > Existing File, select your Icon.

You'll see that a Resources folder appeared. This was my problem, I had to click the loaded icon (in Resources directory), and set "Copy to Output Directory" to "Copy always". (was set "Do not copy").

Now simply do:

Icon myIcon = new Icon("Resources/myIcon.ico");

Or have a function like:

def Print(s):
   return sys.stdout.write(str(s))

Then now:

for i in range(10): # or `xrange` for python 2 version
   Print(i)

Outputs:

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.

When you declare:

new Vue({
    el: '#app',
    data () {
      return {}
    }
)}

That is typically your root Vue instance that the rest of the application descends from. This hangs off the root element declared in an html document, for example:

<html>
  ...
  <body>
    <div id="app"></div>
  </body>
</html>

The other syntax is declaring a component which can be registered and reused later. For example, if you create a single file component like:

// my-component.js
export default {
    name: 'my-component',
    data () {
      return {}
    }
}

You can later import this and use it like:

// another-component.js
<template>
  <my-component></my-component>
</template>
<script>
  import myComponent from 'my-component'
  export default {
    components: {
      myComponent
    }
    data () {
      return {}
    }
    ...
  }
</script>

Also, be sure to declare your data properties as functions, otherwise they are not going to be reactive.

You could compare DOM elements. Remember that jQuery selectors return arrays which will never be equal in the sense of reference equality.

Assuming:

<div id="a" class="a"></div>

this:

$('div.a')[0] == $('div#a')[0]

returns true.

just do:

and it will be displayed as if you typed:

set /p Build=<version.txt
echo %Build%

As per my usage above v.4 this gonna work

$('#selectID').on("select2:select", function(e) {

And for less then v.4 this gonna work:

$('#selectID').on("change", function(e) { 
   //var value = e.params.data; Using {id,text} format
});

JWT is an open standard that defines a compact and self-contained way for securely transmitting information between parties. It is an authentication protocol where we allow encoded claims (tokens) to be transferred between two parties (client and server) and the token is issued upon the identification of a client. With each subsequent request we send the token.

Whereas OAuth2 is an authorization framework, where it has a general procedures and setups defined by the framework. JWT can be used as a mechanism inside OAuth2.

Using the builtin Date.parse function which accepts input in ISO8601 format and directly returns the desired integer return value:

var dates_as_int = dates.map(Date.parse);

Decorator is a function that takes a function as an argument and returns closure. Closure is a set of inner function and free variable. Inner function is closing over free variable and that is why it is called 'closure'. Free variable is variable that outside the inner function and passed in to inner via docorator.

As the name says, decorator is decorating the received function.

function decorator(undecorated_func):
    print("calling decorator func")
    inner():
       print("I am inside inner")
       return undecorated_func
    return inner

this is a simple decorator function. It received "undecorated_func" and passed it to inner() as a free variable, inner() printed "I am inside inner" and returned undecorated_func. When we call decorator(undecorated_func), it is returning the inner. Here is the key, in decorators we are naming the inner function as the name of the function that we passed.

   undecorated_function= decorator(undecorated_func) 

now inner function is called "undecorated_func". Since inner is now named as "undecorated_func", we passed "undecorated_func" to the decorator and we returned "undecorated_func" plus printed out "I am inside inner". so this print statement decorated our "undecorated_func".

now lets define a class with property decorator:

class Person:
    def __init__(self,name):
        self._name=name
    @property
    def name(self):
        return self._name
    @name.setter
    def name(self.value):
        self._name=value

when we decorated name() with @property(), this is what happened:

name=property(name) # Person.__dict__ you ll see name 

first argument of property() is getter. this is what happened in the second decoration:

   name=name.setter(name) 

As I mentioned above, decorator returns the inner function, and we name the inner function with the name of the function that we passed.

Here is an important thing to be aware of. "name" is immutable. in the first decoration we got this:

  name=property(name)

in the second one we got this

  name=name.setter(name)

We are not modifying name obj. In the second decoration, python sees that this is property object and it already had getter. So python creates a new "name" object, adds the "fget" from the first obj and then sets the "fset".

Here is the best option scroll to bottom for table grid, it will be scroll to the last row of the table grid :

 $('.add-row-btn').click(function () {
     var tempheight = $('#PtsGrid > table').height();
     $('#PtsGrid').animate({
         scrollTop: tempheight
         //scrollTop: $(".scroll-bottom").offset().top
     }, 'slow');
 });

TL;DR

1. I prefer to use FormGroup to populate the list of checkbox
2. Write a custom validator for check at least one checkbox was selected
3. Working example https://stackblitz.com/edit/angular-validate-at-least-one-checkbox-was-selected

This also struck me for sometimes so I did try both FormArray and FormGroup approaches.

Most of the time, the list of checkbox was populated on the server and I received it through API. But sometimes you will have a static set of checkbox with your predefined value. With each use case, the corresponding FormArray or FormGroup will be used.

Basically FormArray is a variant of FormGroup. The key difference is that its data gets serialized as an array (as opposed to being serialized as an object in case of FormGroup). This might be especially useful when you don’t know how many controls will be present within the group, like dynamic forms.

For the sake of simplicity, imagine you have a simple create product form with

• One required product name textbox.
• A list of category to select from, required at least one to be checked. Assume the list will be retrieved from the server.

First, I set up a form with only product name formControl. It is a required field.

this.form = this.formBuilder.group({
    name: ["", Validators.required]
});

Since the category is dynamically rendering, I will have to add these data into the form later after the data was ready.

this.getCategories().subscribe(categories => {
    this.form.addControl("categoriesFormArr", this.buildCategoryFormArr(categories));
    this.form.addControl("categoriesFormGroup", this.buildCategoryFormGroup(categories));
})

There are two approaches to build up the category list.

1. Form Array

  buildCategoryFormArr(categories: ProductCategory[], selectedCategoryIds: string[] = []): FormArray {
    const controlArr = categories.map(category => {
      let isSelected = selectedCategoryIds.some(id => id === category.id);
      return this.formBuilder.control(isSelected);
    })
    return this.formBuilder.array(controlArr, atLeastOneCheckboxCheckedValidator())
  }

<div *ngFor="let control of categoriesFormArr?.controls; let i = index" class="checkbox">
  <label><input type="checkbox" [formControl]="control" />
    {{ categories[i]?.title }}
  </label>
</div>

This buildCategoryFormGroup will return me a FormArray. It also take a list of selected value as an argument so If you want to reuse the form for edit data, it could be helpful. For the purpose of create a new product form, it is not be applicable yet.

Noted that when you try to access the formArray values. It will looks like [false, true, true]. To get a list of selected id, it required a bit more work to check from the list but based on the array index. Doesn't sound good to me but it works.

get categoriesFormArraySelectedIds(): string[] {
  return this.categories
  .filter((cat, catIdx) => this.categoriesFormArr.controls.some((control, controlIdx) => catIdx === controlIdx && control.value))
  .map(cat => cat.id);
}

That's why I came up using FormGroup for that matter

2. Form Group

The different of the formGroup is it will store the form data as the object, which required a key and a form control. So it is the good idea to set the key as the categoryId and then we can retrieve it later.

buildCategoryFormGroup(categories: ProductCategory[], selectedCategoryIds: string[] = []): FormGroup {
  let group = this.formBuilder.group({}, {
    validators: atLeastOneCheckboxCheckedValidator()
  });
  categories.forEach(category => {
    let isSelected = selectedCategoryIds.some(id => id === category.id);
    group.addControl(category.id, this.formBuilder.control(isSelected));
  })
  return group;
}

<div *ngFor="let item of categories; let i = index" class="checkbox">
  <label><input type="checkbox" [formControl]="categoriesFormGroup?.controls[item.id]" /> {{ categories[i]?.title }}
  </label>
</div>

The value of the form group will look like:

{
    "category1": false,
    "category2": true,
    "category3": true,
}

But most often we want to get only the list of categoryIds as ["category2", "category3"]. I also have to write a get to take these data. I like this approach better comparing to the formArray, because I could actually take the value from the form itself.

  get categoriesFormGroupSelectedIds(): string[] {
    let ids: string[] = [];
    for (var key in this.categoriesFormGroup.controls) {
      if (this.categoriesFormGroup.controls[key].value) {
        ids.push(key);
      }
      else {
        ids = ids.filter(id => id !== key);
      }
    }
    return ids;
  }

3. Custom validator to check at least one checkbox was selected

I made the validator to check at least X checkbox was selected, by default it will check against one checkbox only.

export function atLeastOneCheckboxCheckedValidator(minRequired = 1): ValidatorFn {
  return function validate(formGroup: FormGroup) {
    let checked = 0;

    Object.keys(formGroup.controls).forEach(key => {
      const control = formGroup.controls[key];

      if (control.value === true) {
        checked++;
      }
    });

    if (checked < minRequired) {
      return {
        requireCheckboxToBeChecked: true,
      };
    }

    return null;
  };
}

actually I found a novel solution that really helped me out, If you are especially concerned with the index of a certain value in a list or data set, you can just set the value of dictionary to that Index!:

Just watch:

list = ['a', 'b', 'c']
dictionary = {}
counter = 0
for i in list:
   dictionary[i] = counter
   counter += 1

print(dictionary) # dictionary = {'a':0, 'b':1, 'c':2}

Now through the power of hashmaps you can pull the index your entries in constant time (aka a whole lot faster)

You can not ask for instance during configuration phase - you can ask only for providers.

var app = angular.module('modx', []);

// configure stuff
app.config(function($routeProvider, $locationProvider) {
  // you can inject any provider here
});

// run blocks
app.run(function($rootScope) {
  // you can inject any instance here
});

See http://docs.angularjs.org/guide/module for more info.

Here is a shorter solution by AbacusUtil

Stream.of(input).toMap(e -> e.getKey().substring(subLength), 
                       e -> AttributeType.GetByName(e.getValue()));

I know I'm replying to an old question, but I just went through this same exercise and found out a bit more information, that I think will contribute a lot to the discussion and help out anyone else who finds this question and sees where the existing answers fall short.

The accepted answer is close, and can be corrected using Nedko's comment to it. A more detailed understanding of the WMI Classes involved helps complete the picture.

Win32_USBHub returns only USB Hubs. That seems obvious in hindsight but the discussion above misses it. It does not include all possible USB devices, only those which can (in theory, at least) act as a hub for additional devices. It misses some devices that are not hubs (particularly parts of composite devices).

Win32_PnPEntity does include all the USB devices, and hundreds more non-USB devices. Russel Gantman's advice to use a WHERE clause search Win32_PnPEntity for a DeviceID beginning with "USB%" to filter the list is helpful but slightly incomplete; it misses bluetooth devices, some printers/print servers, and HID-compliant mice and keyboards. I have seen "USB\%", "USBSTOR\%", "USBPRINT\%", "BTH\%", "SWD\%", and "HID\%". Win32_PnPEntity is, however, a good "master" reference to look up information once you are in possession of the PNPDeviceID from other sources.

What I found was the best way to enumerate USB devices was to query Win32_USBControllerDevice. While it doesn't give detailed information for the devices, it does completely enumerate your USB devices and gives you an Antecedent/Dependent pair of PNPDeviceIDs for every USB Device (including Hubs, non-Hub devices, and HID-compliant devices) on your system. Each Dependent returned from the query will be a USB Device. The Antecedent will be the Controller it is assigned to, one of the USB Controllers returned by querying Win32_USBController.

As a bonus, it appears that under the hood, WMI walks the Device Tree when responding to the Win32_USBControllerDevice query, so the order in which these results are returned can help identify parent/child relationships. (This is not documented and is thus only a guess; use the SetupDi API's CM_Get_Parent (or Child + Sibling) for definitive results.) As an option to the SetupDi API, it appears that for all the devices listed under Win32_USBHub they can be looked up in the registry (at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\ + PNPDeviceID) and will have a parameter ParentIdPrefix which will be the prefix of the last field in the PNPDeviceID of its children, so this could also be used in a wildcard match to filter the Win32_PnPEntity query.

In my application, I did the following:

• (Optional) Queried Win32_PnPEntity and stored the results in a key-value map (with PNPDeviceID as the key) for later retrieval. This is optional if you want to do individual queries later.
• Queried Win32_USBControllerDevice for a definitive list of USB devices on my system (all the Dependents) and extracted the PNPDeviceIDs of these. I went further, based on order following the device tree, to assign devices to the root hub (the first device returned, rather than the controller) and built a tree based on the parentIdPrefix. The order the query returns, which matches device tree enumeration via SetupDi, is each root hub (for whom the Antecedent identifies the controller), followed by an iteration of devices under it, e.g., on my system:
  • Root hub of first controller
  • Root hub of second controller
    • First hub under root hub of second controller (has parentIdPrefix)
      • First composite device under first hub under root hub of second controller (PNPDeviceID matches above hub's ParentIdPrefix; has its own ParentIdPrefix)
        • HID Device part of the composite device (PNPDeviceID matches above composite device's ParentIDPrefix)
      • Second device under first hub under root hub of second controller
        • HID Device part of the composite device
    • Second hub under root hub of second controller
      • First device under second hub under root hub of second controller
    • Third hub under root hub of second controller
    • etc.
• Queried Win32_USBController. This gave me the detailed information of the PNPDeviceIDs of my controllers which are at the top of the device tree (which were the Antecedents of the previous query). Using the tree derived in the previous step, recursively iterated over its children (the root hubs) and their children (the other hubs) and their children (non-hub devices and composite devices) and their children, etc.
  • Retrieved details for each device in my tree by referencing the map stored in the first step. (Optionally, one could skip the first step, and query Win32_PnPEntity individually using the PNPDeviceId to get the information at this step; probably a cpu vs. memory tradeoff determining which order is better.)

In summary, Win32USBControllerDevice Dependents are a complete list of USB Devices on a system (other than the Controllers themselves, which are the Antecedents in that same query), and by cross-referencing these PNPDeviceId pairs with information from the registry and from the other queries mentioned, a detailed picture can be constructed.

if you use the eclipse, see the bellow image to allow the compiler to store the information about method parameters

The problem id because of inp.read(); method. Its return single character at a time and because you are storing it into int type of array so that is just storing ascii value of that.

What you can do simply

for(int i=0;i<T;i++) {
    String s= inp.readLine();
    String[] intValues = inp.readLine().split(" ");
    int[] m= new int[2];
    m[0]=Integer.parseInt(intValues[0]);
    m[1]=Integer.parseInt(intValues[1]);

    // Checking whether I am taking the inputs correctly
    System.out.println(s);
    System.out.println(m[0]);
    System.out.println(m[1]);
}

DF[:-n]

where n is the last number of rows to drop.

To drop the last row :

DF = DF[:-1]

You have to put:

<html ng-app="urlApp" ng-controller="urlCtrl">

This way the angular function can access into "window" object

create java application in which you define two threads namely t1 and t2, thread t1 will generate random number 0 and 1 (simulate toss a coin ). 0 means head and one means tail. the other thread t2 will do the same t1 and t2 will repeat this loop 100 times and finally your application should determine how many times t1 guesses the number generated by t2 and then display the score. for example if thread t1 guesses 20 number out of 100 then the score of t1 is 20/100 =0.2 if t1 guesses 100 numbers then it gets score 1 and so on

If we wanted to retrieve or update these attributes using existing, native JavaScript, then we can do so using the getAttribute and setAttribute methods as shown below:

JavaScript

<script>
// 'Getting' data-attributes using getAttribute
var plant = document.getElementById('strawberry-plant');
var fruitCount = plant.getAttribute('data-fruit'); // fruitCount = '12'

// 'Setting' data-attributes using setAttribute
plant.setAttribute('data-fruit','7'); // Pesky birds
</script>

Through jQuery

// Fetching data
var fruitCount = $(this).data('fruit');

// Above does not work in firefox. So use below to get attribute value.
var fruitCount = $(this).attr('data-fruit');

// Assigning data
$(this).data('fruit','7');

// But when you get the value again, it will return old value. 
// You have to set it as below to update value. Then you will get updated value.
$(this).attr('data-fruit','7'); 

Read this documentation for vanilla js or this documentation for jquery

There's a property that enables/disables in line media playback in the iOS web browser (if you were writing a native app, it would be the allowsInlineMediaPlayback property of a UIWebView). By default on iPhone this is set to NO, but on iPad it's set to YES.

Fortunately for you, you can also adjust this behaviour in HTML as follows:

<video id="myVideo" width="280" height="140" webkit-playsinline>

...that should hopefully sort it out for you. I don't know if it will work on your Android devices. It's a webkit property, so it might. Worth a go, anyway.

And you'll have something like this in the bottom right

I had a fair amount of difficulty with a solution something very similar to this: trying to have two buttons in a TableRow, with each being half the screen width. For whatever reason, the left button would always be about 70% of the width, and the right button 30%. Calling table_layout.setStretchAllColumns(true) had no effect, nor did setting the button's width to half the screen, nor setting their layout weight.

The solution I ended up with was nesting a LinearLayout in the TableRows, which did take into account the value of the buttons' width.

    TableLayout layout = new TableLayout(this);
    TableRow top_row = new TableRow(this);
    left_button = styleButton();
    right_button = styleButton();
    LinearLayout toprow_layout = new LinearLayout (this);
    toprow_layout.setOrientation(LinearLayout.HORIZONTAL);
    toprow_layout.addView (left_button);
    toprow_layout.addView(right_button);
    toprow.addView(top_layout);
    layout.addView(top_row)

    private Button styleButton() {
            Button btn = new Button (this);
            android.view.Display display = ((android.view.WindowManager)getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();      
            btn.setWidth((int)(display.getWidth()/2));    // set width to half
            btn.setHeight(((int)display.getHeight()/6));  // set height to whatevs
            btn.setText("foo");
            return btn;
        }

I had the same problem. The problem was because one of my php files was in utf-8 (the most important, the configuaration file which is included in all php files).

In my case, I had 2 different solutions which worked for me :

First, I changed the Apache Configuration by using AddDefaultCharsetDirective in configuration files (or in .htaccess). This solution forces Apache to use the correct encodage.

AddDefaultCharset ISO-8859-1

The second solution was to change the bad encoding of the php file.

you'd use another join, something along these lines:

SELECT toD.dom_url AS ToURL, 
    fromD.dom_url AS FromUrl, 
    rvw.*

FROM reviews AS rvw

LEFT JOIN domain AS toD 
    ON toD.Dom_ID = rvw.rev_dom_for

LEFT JOIN domain AS fromD 
    ON fromD.Dom_ID = rvw.rev_dom_from

EDIT:

All you're doing is joining in the table multiple times. Look at the query in the post: it selects the values from the Reviews tables (aliased as rvw), that table provides you 2 references to the Domain table (a FOR and a FROM).

At this point it's a simple matter to left join the Domain table to the Reviews table. Once (aliased as toD) for the FOR, and a second time (aliased as fromD) for the FROM.

Then in the SELECT list, you will select the DOM_URL fields from both LEFT JOINS of the DOMAIN table, referencing them by the table alias for each joined in reference to the Domains table, and alias them as the ToURL and FromUrl.

For more info about aliasing in SQL, read here.

You can't import classes from the default package. You should avoid using the default package except for very small example programs.

From the Java language specification:

It is a compile time error to import a type from the unnamed package.

Another option:

sort file1 file2 | uniq -u > file3

If you want to see just the duplicate entries use "uniq -d" option:

sort file1 file2 | uniq -d > file3

You need to slightly modify your compare function and use functools.cmp_to_key to pass it to sorted. Example code:

import functools

lst = [list(range(i, i+5)) for i in range(5, 1, -1)]

def fitness(item):
    return item[0]+item[1]+item[2]+item[3]+item[4]
def compare(item1, item2):
    return fitness(item1) - fitness(item2)

sorted(lst, key=functools.cmp_to_key(compare))

Output:

[[2, 3, 4, 5, 6], [3, 4, 5, 6, 7], [4, 5, 6, 7, 8], [5, 6, 7, 8, 9]]

Works :)

I feed a 514 dimensional real-valued input to a Sequential model in Keras. My model is constructed in following way :

    predictivemodel = Sequential()
    predictivemodel.add(Dense(514, input_dim=514, W_regularizer=WeightRegularizer(l1=0.000001,l2=0.000001), init='normal'))
    predictivemodel.add(Dense(257, W_regularizer=WeightRegularizer(l1=0.000001,l2=0.000001), init='normal'))
    predictivemodel.compile(loss='mean_squared_error', optimizer='adam', metrics=['accuracy'])

When I print model.summary() I get following result:

Layer (type)    Output Shape  Param #     Connected to                   
================================================================
dense_1 (Dense) (None, 514)   264710      dense_input_1[0][0]              
________________________________________________________________
activation_1    (None, 514)   0           dense_1[0][0]                    
________________________________________________________________
dense_2 (Dense) (None, 257)   132355      activation_1[0][0]               
================================================================
Total params: 397065
________________________________________________________________ 

For the dense_1 layer , number of params is 264710. This is obtained as : 514 (input values) * 514 (neurons in the first layer) + 514 (bias values)

For dense_2 layer, number of params is 132355. This is obtained as : 514 (input values) * 257 (neurons in the second layer) + 257 (bias values for neurons in the second layer)

Just to extend on the previous answer, if you are linking two requests together and want to send the cookies returned from the first one to the second one (for example, maintaining a session alive across requests) you can do:

import requests
r1 = requests.post('http://www.yourapp.com/login')
r2 = requests.post('http://www.yourapp.com/somepage',cookies=r1.cookies)

If you use the static method and load the properties file from the classpath folder so you can use the below code :

//load a properties file from class path, inside static method
Properties prop = new Properties();
prop.load(Classname.class.getClassLoader().getResourceAsStream("foo.properties"));

I just had this same problem. 4 statements in SSMS instead of using the GUI and it was very fast.

• Make a new column

  alter table users add newusernum int;

• Copy values over

  update users set newusernum=usernum;

• Drop the old column

  alter table users drop column usernum;

• Rename the new column to the old column name

  EXEC sp_RENAME 'users.newusernum' , 'usernum', 'COLUMN';

marc_s's Answer Snap

None of the solutions above work perfectly.They either loses CSS or have to include/edit external CSS file. I found a perfect solution that will not lose your CSS nor you have to edit/add external CSS.

HTML:

<div id='printarea'>
    <p>This is a sample text for printing purpose.</p>
    <input type='button' id='btn' value='Print' onclick='printFunc();'>
</div>
<p>Do not print.</p

JQuery:

function printFunc() {
    var divToPrint = document.getElementById('printarea');
    var htmlToPrint = '' +
        '<style type="text/css">' +
        'table th, table td {' +
        'border:1px solid #000;' +
        'padding;0.5em;' +
        '}' +
        '</style>';
    htmlToPrint += divToPrint.outerHTML;
    newWin = window.open("");
    newWin.document.write("<h3 align='center'>Print Page</h3>");
    newWin.document.write(htmlToPrint);
    newWin.print();
    newWin.close();
    }

The other answers are correct: You don't have a default value. However, you have another problem in your logic:

You read the same file twice. After reading it once, the cursor is at the end of the file. To solve this, you can do two things: Either open/close the file upon each function call:

def temp_sky(lreq, breq):
    with open("/home/path/to/file",'r') as tfile:
        # do your stuff

This hase the disadvantage of having to open the file each time. The better way would be:

tfile.seek(0)

You do this after your for line in tfile: loop. It resets the cursor to the beginning to the next call will start from there again.
