$ git clone --no-hardlinks /path/to/repo

The above command uses POSIX path notation for the directory with your git repository. For Windows it is (directory C:/path/to/repo contains .git directory):

C:\some\dir\> git clone --local file:///C:/path/to/repo my_project

The repository will be clone to C:\some\dir\my_project. If you omit file:/// part then --local option is implied.

Sometimes its because of ssh. So you can use this:

git clone https://cfdem.git.sourceforge.net/gitroot/cfdem/liggghts

instead of:

git clone git://cfdem.git.sourceforge.net/gitroot/cfdem/liggghts

In Bitbucket Server you can do a download by clicking on ... next to the branch and then Download

For more info see Download an archive from Bitbucket Server

As of early 2017, the answer in this comment works:

git fetch <origin-name> <branch-name> brings the branch down for you. While this doesn't pull all branches at once, you can singularly execute this per-branch.

Use --single-branch option to only clone history leading to tip of the tag. This saves a lot of unnecessary code from being cloned.

git clone <repo_url> --branch <tag_name> --single-branch

Use the GitHub Network Graph to Track Forks

You have no way to see who has checked out your repository using standard git commands such as git clone, but you can see who has forked your repository on GitHub using the Network Graph Visualizer. At the time of this answer, you can access this feature in at least two ways:

1. From the "Network" tab just to the right of the "Code" tab on the navigation bar at the top of your repository.
2. By clicking on the numbers (if non-zero) in the call-out just to the right of the "Fork" widget on the right-hand side.

For example, here is a partial screenshot of the rbenv network graph:

The "Members" tab at the top of the Network Graph will also show you a different view, listing the names of the people who currently have forks on GitHub. It obviously will not show people who cloned outside of GitHub, or folks who have subsequently deleted their forks.

Fork Vs. Clone - two words that both mean copy

Please see this diagram. _{^{(Originally from http://www.dataschool.io/content/images/2014/Mar/github1.png).}}

Fork

• A copy to your remote repo (cloud) that links it to Joe's
• A copy you can then clone to your local repo and F*%$-up
• When you are done you can push back to your remote
• You can then ask Joe if he wants to use it in his project by clicking pull-request

Clone

• a copy to your local repo (harddrive)

Easy way to do this issue
try this.

Step 1:

ls -al ~/.ssh

Step 2:

ssh-keygen 

(using enter key for default value) Step 3: To setup config file

vim /c/Users/Willie/.ssh/config

Host gitlab.com
HostName gitlab.com
User git
IdentityFile ~/.ssh/id_rsa

Step 4:

git clone [email protected]:<username>/test2.git

Step 5:
When you finished Step 4
1.the test2.git file will be download done
2.you will get the new file(known_hosts) in the ~/.ssh

PS: I create the id_rsa and id_rsa.ub by meself and I deliver it to the Gitlab server. using both keys to any client-sides(windows and Linux).

EDIT: As of Git 2.19, this is finally possible, as can be seen in this answer.

Consider upvoting that answer.

Note: in Git 2.19, only client-side support is implemented, server-side support is still missing, so it only works when cloning local repositories. Also note that large Git hosters, e.g. GitHub, don't actually use the Git server, they use their own implementation, so even if support shows up in the Git server, it does not automatically mean that it works on Git hosters. (OTOH, since they don't use the Git server, they could implement it faster in their own implementations before it shows up in Git server.)

No, that's not possible in Git.

Implementing something like this in Git would be a substantial effort and it would mean that the integrity of the clientside repository could no longer be guaranteed. If you are interested, search for discussions on "sparse clone" and "sparse fetch" on the git mailinglist.

In general, the consensus in the Git community is that if you have several directories that are always checked out independently, then these are really two different projects and should live in two different repositories. You can glue them back together using Git Submodules.

Source: Set Up Git

The following command will save your password in memory for some time (for Git 1.7.10 or newer).

$ git config --global credential.helper cache
# Set git to use the credential memory cache

$ git config --global credential.helper 'cache --timeout=3600'
# Set the cache to timeout after one hour (setting is in seconds)

If there is still issue around access after creating SSH and adding it in your Bitbucket account or wherever, you need to do the following in terminal on GitBash, OSX or Linux:

# Lists already added identities (‘ssh keys’)
ssh-add -l

Then, if you don't see your key listed, add it with the following (replace identity with its real name):

# Add a new identity
ssh-add ~/.ssh/identity

This worked for me.

You can make git replace the protocol for you

git config --global url."https://".insteadOf git://

See more at SO Bower install using only https?

See some of the answers to my similar question why-cant-i-push-from-a-shallow-clone and the link to the recent thread on the git list.

Ultimately, the 'depth' measurement isn't consistent between repos, because they measure from their individual HEADs, rather than (a) your Head, or (b) the commit(s) you cloned/fetched, or (c) something else you had in mind.

The hard bit is getting one's Use Case right (i.e. self-consistent), so that distributed, and therefore probably divergent repos will still work happily together.

It does look like the checkout --orphan is the right 'set-up' stage, but still lacks clean (i.e. a simple understandable one line command) guidance on the "clone" step. Rather it looks like you have to init a repo, set up a remote tracking branch (you do want the one branch only?), and then fetch that single branch, which feels long winded with more opportunity for mistakes.

Edit: For the 'clone' step see this answer

Regarding this line from the original post:

"I know how to move the files after I've cloned the repo, but this seems to break git"

I am able to do that and I don't see any issues so far with my add, commit, push, pull operations.

This approach is stated above, but just not broken down into steps. Here's the steps that work for me:

1. clone the repo into any fresh temporary folder
2. cd into that root folder you just cloned locally
3. copy the entire contents of the folder, including the /.git directory - into any existing folder you like; (say an eclipse project that you want to merge with your repo)

The existing folder you just copied the files into , is now ready to interact with git.

you can use this command to git single branch and rename the folder if you want to keep branched stand alone

git clone -b [branch-name] --single-branch [url]  [folder_name]

example

git clone -b mybranch --single-branch git://github/repository.git  project_mybranch

I used this to clone a repo to the current directory, which wasn't empty. Not necessarily clean living, but it was in a disposable docker container:

git clone https://github.com/myself/myRepo.git temp
cp -r temp/* .
rm -rf temp

Here, I used cp -r instead of mv, since that copies hidden files and directories. Then dispose of the temporary directory with rm -rf

"Fork" in this context means "Make a copy of their code so that I can add my own modifications". There's not much else to say. Every clone is essentially a fork, and it's up to the original to decide whether to pull the changes from the fork.

Checking out Tags

If you want to view the versions of files a tag is pointing to, you can do a git checkout, though this puts your repository in “detached HEAD” state, which has some ill side effects:

$ git checkout 2.0.0
Note: checking out '2.0.0'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

HEAD is now at 99ada87... Merge pull request #89 from schacon/appendix-final

$ git checkout 2.0-beta-0.1
Previous HEAD position was 99ada87... Merge pull request #89 from schacon/appendix-final
HEAD is now at df3f601... add atlas.json and cover image

In “detached HEAD” state, if you make changes and then create a commit, the tag will stay the same, but your new commit won’t belong to any branch and will be unreachable, except for by the exact commit hash. Thus, if you need to make changes—say you’re fixing a bug on an older version, for instance—you will generally want to create a branch:

$ git checkout -b version2 v2.0.0
Switched to a new branch 'version2'

If you do this and make a commit, your version2 branch will be slightly different than your v2.0.0 tag since it will move forward with your new changes, so do be careful.

$ git clone --bare https://github.com/example

This command will make the new "example" directory itself the $GIT_DIR (instead of example/.git). Also the branch heads at the remote are copied directly to corresponding local branch heads, without mapping. When this option is used, neither remote-tracking branches nor the related configuration variables are created.

$ git clone --mirror https://github.com/example

As with a bare clone, a mirrored clone includes all remote branches and tags, but all local references (including remote-tracking branches, notes etc.) will be overwritten each time you fetch, so it will always be the same as the original repository.

You've already discovered the simplest way to specify a shallow clone in Git-SVN, by specifying the SVN revision number that you want to start your clone at ( -r$REV:HEAD).

For example: git svn clone -s -r1450:HEAD some/svn/repo

Git's data structure is based on pointers in a directed acyclic graph (DAG), which makes it trivial to walk back n commits. But in SVN ( and therefore in Git-SVN) you will have to find the revision number yourself.

Your current directory does not has the write/create permission to create kivy directory, thats why occuring this problem.

Your current directory give 777 rights and try it.

sudo chmod 777 DIR_NAME
cd DIR_NAME
git clone https://github.com/mygitusername/kivy.git

Oneliner for doing all of the above operations:

for i in `ls -A .`; do if [ $i != ".git" ]; then rm -rf $i; fi; done; mv .git/* .; rm -rf .git; git config --bool core.bare true

(don't blame me if something blows up and you didn't have backups :P)

git --branch <branchname> <url>

But bash completion don't get this key: --branch

TL;DR - Just create a tag in the source repository against the commit you want to clone up to and use the tag in the fetch command. You can delete the tag from the original repo later to clean up.

Well, its 2014 and it looks like Charles Bailey's accepted answer from 2010 is well and truly outdated by now and most (all?) of the other answers involve cloning, which many people are hoping to avoid.

The following solution achieves what the OP and many others are looking for, which is a way to create a copy of a repository, including history, but only up to a certain commit.

Here are the commands I used with git version 2.1.2 to clone a local repo (ie. a repository in another directory) up to a certain point:

# in the source repository, create a tag against the commit you want to check out
git tag -m "Temporary tag" tmptag <sha1>

# create a new directory and change into that directory
cd somewhere_else;mkdir newdir;cd newdir

# ...and create a new repository
git init

# add the source repository as a remote (this can be a URL or a directory)
git remote add origin /path/to/original/repo

# fetch the tag, which will include the entire repo and history up to that point
git fetch origin refs/tags/tmptag

# reset the head of the repository
git reset --hard FETCH_HEAD

# you can now change back to the original repository and remove the temporary tag
cd original_repo
git tag -d tmptag

Hopefully this solution keeps working for a few more years! :-)

This is the command that you need to execute on the mirror:

git remote update

It is worth mentioning that the command works similarly on Linux:

git clone path/to/source/folder path/to/destination/folder

since you only want the files, you don't need to treat it as a git repo.

rsync -rlp --exclude '.git' user@host:path/to/git/repo/ .

and this only works with local path and remote ssh/rsync path, it may not work if the remote server only provides git:// or https:// access.

You can solve it like this:

git reset --hard sha

where sha e.g.: 85a108ec5d8443626c690a84bc7901195d19c446

You can get the desired sha with the command:

git log

There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.

Similarity::Similarity() or Similarity::~Similarity() are just missing and you have defined the others incorrectly,

void Similarity::readData(Scanner& inStream){
}

not

void readData(Scanner& inStream){
}

etc. etc.

The second one is a function called readData, only the first is the readData method of the Similarity class.

To be clear about this, in Similarity.h

void readData(Scanner& inStream);

but in Similarity.cpp

void Similarity::readData(Scanner& inStream){
}

You can also user java Regular Expression. String.split() also uses the expression internally. Refer http://download.oracle.com/javase/1.4.2/docs/api/java/util/regex/Pattern.html

Change the content type to 'application/x-www-form-urlencoded'

I think error is not coming from the specified line but from the first 3 lines. Try this instead :

node {
   stage("first") {
     def foo = "foo"
     sh "echo ${foo}"
   }
}

I think you had some extra lines that are not valid...

From declaractive pipeline model documentation, it seems that you have to use an environment declaration block to declare your variables, e.g.:

pipeline {
   environment {
     FOO = "foo"
   }

   agent none
   stages {
       stage("first") {
           sh "echo ${FOO}"
       }
   }
}

Use $ne (for "not equal")

db.collection.find({ "fieldToCheck": { $exists: true, $ne: null } })

This has been answered above, but I wanted to suggest an alternative.

When in the Build Settings for you project or target, you can go to the Editor menu and select Show Setting Names from the menu. This will change all of the options in the Build Settings pane to the build variable names. The option in the menu changes to Show Setting Titles, select this to change back to the original view.

This can be handy when you know what build setting you want to use in a script, toggle the setting names in the menu and you can see the variable name.

Use <div id="rectangle" style="width:number px; height:number px; background-color:blue"></div>

This will create a blue rectangle.

Add nth Days, months and years

$n = 2;
for ($i = 0; $i <= $n; $i++){
    $d = strtotime("$i days");
    $x = strtotime("$i month");
    $y = strtotime("$i year");
    echo "Dates : ".$dates = date('d M Y', "+$d days");
    echo "<br>";
    echo "Months : ".$months = date('M Y', "+$x months");
    echo '<br>';
    echo "Years : ".$years = date('Y', "+$y years");
    echo '<br>';
}

You can use extension called Markdown Syntax Highlighting for Notepad++. It is available on Github

After installation, new option in the Language dropdown will be appeared

<img style="width: 50%;" src="..." />

worked just fine for me ... Or am I missing something?

Edit: But see Shawn's caveat about accidentally upsizing.

Math.Pow() returns double so nice would be to write like this:

double d = Math.Pow(100.00, 3.00);

I know this isn't exactly how you want to do this, but it could be a start:

SELECT *
FROM (SELECT *, DATEPART(yy, column_dateTime) as Year, 
      DATEPART(mm, column_dateTime) as Month, 
      DATEPART(dd, column_dateTime) as Day 
      FROM table1)
WHERE Year = '2008'
AND Month = '8'
AND Day = '14'

I am no expert, but I copy the .git folder to a new folder, then invoke: git reset --hard

Update

Apple has clarified that slicing occurs independent of enabling bitcode. I've observed this in practice as well where a non-bitcode enabled app will only be downloaded as the architecture appropriate for the target device.

Original

More specifically:

Bitcode. Archive your app for submission to the App Store in an intermediate representation, which is compiled into 64- or 32-bit executables for the target devices when delivered.

Slicing. Artwork incorporated into the Asset Catalog and tagged for a platform allows the App Store to deliver only what is needed for installation.

The way I read this, if you support bitcode, downloaders of your app will only get the compiled architecture needed for their own device.

condition1 = False
condition2 = False
val = -1
#here is the function getstuff is not defined, i hope you define it before
#calling it into while loop code

while condition1 and condition2 is False and val == -1:
#as you can see above , we can write that in a simplified syntax.
    val,something1,something2 = getstuff()

    if something1 == 10:
        condition1 = True

    elif something2 == 20:
# here you don't have to use "if" over and over, if have to then write "elif" instead    
    condition2 = True
# ihope it can be helpfull

For i's of user-defined types, these operators could (but should not) have meaningfully different sematics in the context of a loop index, and this could (but should not) affect the behavior of the loop described.

Also, in c++ it is generally safest to use the pre-increment form (++i) because it is more easily optimized. (Scott Langham beat me to this tidbit. Curse you, Scott)

You can combine ID and Class in CSS, but IDs are intended to be unique, so adding a class to a CSS selector would over-qualify it.

It looks like CLR / C# might be getting better support for Vector<> soon.

The problem with using the PasswordBox is that it is not very MVVM friendly due to the fact that it works with SecureString and therefore requires a shim to bind it to a String. You also cannot use the clipboard. While all these things are there for a reason, you may not require that level of security. Here is an alternative approach that works with the clipboard, nothing fancy. You make the TextBox text and background transparent and bind the text to a TextBlock underneath it. This textblock converts characters to * using the converter specified.

<Window.Resources>
    <local:TextToPasswordCharConverter x:Key="TextToPasswordCharConverter" />
</Window.Resources>

<Grid Width="200">
    <TextBlock Margin="5,0,0,0" Text="{Binding Text, Converter={StaticResource TextToPasswordCharConverter}, UpdateSourceTrigger=PropertyChanged, Mode=OneWay}" FontFamily="Consolas" VerticalAlignment="Center" />
    <TextBox Foreground="Transparent" Text="{Binding Text, UpdateSourceTrigger=PropertyChanged}" FontFamily="Consolas" Background="Transparent" />
</Grid>

And here is the Value Converter:

class TextToPasswordCharConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return new String('*', value?.ToString().Length ?? 0);
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

Make sure your Text property on your viewmodel implements INotifyPropertyChanged

I know you all think /D: date is going to use date stuff, but just /D without the: does exactly what we want so...

xcopy {Source} {Destination} /E /D 

Will copy without overwriting to pickup those files that are new or maybe failed before for some reason.

Just try it, it works.

Try this one:

function show_sub(cat) {
    var parent = cat,
    sub = parent.getElementsByClassName('sub');
    if (sub[0].style.display == 'inline'){
        sub[0].style.display = 'none';
    }
    else {
        sub[0].style.display = 'inline';
    }
}

document.getElementById('cat').onclick = function(){
    show_sub(this);
};?

and use this for IE6 & 7

if (typeof document.getElementsByClassName!='function') {
    document.getElementsByClassName = function() {
        var elms = document.getElementsByTagName('*');
        var ei = new Array();
        for (i=0;i<elms.length;i++) {
            if (elms[i].getAttribute('class')) {
               ecl = elms[i].getAttribute('class').split(' ');
                for (j=0;j<ecl.length;j++) {
                    if (ecl[j].toLowerCase() == arguments[0].toLowerCase()) {
                        ei.push(elms[i]);
                    }
                }
            } else if (elms[i].className) {
                ecl = elms[i].className.split(' ');
                for (j=0;j<ecl.length;j++) {
                    if (ecl[j].toLowerCase() == arguments[0].toLowerCase()) {
                        ei.push(elms[i]);
                    }
                }
            }
        }
        return ei;
    }
}

You need something like this:

foreach(DataColumn c in dr.Table.Columns)
{
  MessageBox.Show(c.ColumnName);
}

Try Ctrl + F5 in Visual Studio to run your program, this will add a pause with "Press any key to continue..." automatically without any Console.Readline() or ReadKey() functions.

For adding a new column to an existing CSV file(with headers), if the column to be added has small enough number of values, here is a convenient function (somewhat similar to @joaquin's solution). The function takes the

1. Existing CSV filename
2. Output CSV filename (which will have the updated content) and
3. List with header name&column values

def add_col_to_csv(csvfile,fileout,new_list):
    with open(csvfile, 'r') as read_f, \
        open(fileout, 'w', newline='') as write_f:
        csv_reader = csv.reader(read_f)
        csv_writer = csv.writer(write_f)
        i = 0
        for row in csv_reader:
            row.append(new_list[i])
            csv_writer.writerow(row)
            i += 1 

Example:

new_list1 = ['test_hdr',4,4,5,5,9,9,9]
add_col_to_csv('exists.csv','new-output.csv',new_list1)

Existing CSV file:

I believe your syntax is using the Win32_Product Class in WMI. One cause is that this class only displays products installed using Windows Installer (See Here). The Uninstall Registry Key is your best bet.

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall

UPDATE FOR COMMENTS:

The Uninstall Registry Key is the standard place to list what is installed and what isn't installed. It is the location that the Add/Remove Programs list will use to populate the list of applications. I'm sure that there are applications that don't list themselves in this location. In that case you'd have to resort to another cruder method such as searching the Program Files directory or looking in the Start Menu Programs List. Both of those ways are definitely not ideal.

In my opinion, looking at the registry key is the best method.

I normally use

grep searchstring file -C n # n for number of lines of context up and down

Many of the tools like grep also have really great man files too. I find myself referring to grep's man page a lot because there is so much you can do with it.

man grep

Many GNU tools also have an info page that may have more useful information in addition to the man page.

info grep

My favorite...

SELECT objParent.name AS parent, obj.name, col.*
FROM sysobjects obj 
    LEFT JOIN syscolumns col
        ON obj.id = col.id
    LEFT JOIN sysobjects objParent
        ON objParent.id = obj.parent_obj
WHERE col.name LIKE '%Comment%'
   OR obj.name LIKE '%Comment%'

Above I'm searching for "Comment".

Drop the percent signs if you want a direct match.

This searches tables, fields and things like primary key names, constraints, views, etc.

And when you want to search in StoredProcs after monkeying with the tables (and need to make the procs match), use the following...

SELECT name
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%Comment%'

Hope that helps, I find these two queries to be extremely useful.

First, I'd like to apologize for bringing this question back up, but I felt that it could use another answer.

Derek Schultz is kind of correct. The '\b' character moves the printing cursor one character backwards, allowing you to overwrite the character that was printed there (it does not delete the entire line or even the character that was there unless you print new information on top). The following is an example of a progress bar using Java though it does not follow your format, it shows how to solve the core problem of overwriting characters (this has only been tested in Ubuntu 12.04 with Oracle's Java 7 on a 32-bit machine, but it should work on all Java systems):

public class BackSpaceCharacterTest
{
    // the exception comes from the use of accessing the main thread
    public static void main(String[] args) throws InterruptedException
    {
        /*
            Notice the user of print as opposed to println:
            the '\b' char cannot go over the new line char.
        */
        System.out.print("Start[          ]");
        System.out.flush(); // the flush method prints it to the screen

        // 11 '\b' chars: 1 for the ']', the rest are for the spaces
        System.out.print("\b\b\b\b\b\b\b\b\b\b\b");
        System.out.flush();
        Thread.sleep(500); // just to make it easy to see the changes

        for(int i = 0; i < 10; i++)
        {
            System.out.print("."); //overwrites a space
            System.out.flush();
            Thread.sleep(100);

I added @Component annotation from import org.springframework.stereotype.Component and the problem was solved.

Create a function like so:

CREATE FUNCTION dbo.fn_FileExists(@path varchar(512))
RETURNS BIT
AS
BEGIN
     DECLARE @result INT
     EXEC master.dbo.xp_fileexist @path, @result OUTPUT
     RETURN cast(@result as bit)
END;
GO

Edit your table and add a computed column (IsExists BIT). Set the expression to:

dbo.fn_FileExists(filepath)

Then just select:

SELECT * FROM dbo.MyTable where IsExists = 1

Update:

To use the function outside a computed column:

select id, filename, dbo.fn_FileExists(filename) as IsExists
from dbo.MyTable

Update:

If the function returns 0 for a known file, then there is likely a permissions issue. Make sure the SQL Server's account has sufficient permissions to access the folder and files. Read-only should be enough.

And YES, by default, the 'NETWORK SERVICE' account will not have sufficient right into most folders. Right click on the folder in question and select 'Properties', then click on the 'Security' tab. Click 'Edit' and add 'Network Service'. Click 'Apply' and retest.

Well, it's not a direct answer to your question, but there's a tool in GNU/Linux whose job is to rotate log files on regular basis, keeping old ones zipped up to a certain limit. It's logrotate

I find this particularly useful for when you want to 'store' a function call.

For example, suppose I have some unit tests for a function 'add':

def add(a, b): return a + b
tests = { (1,4):5, (0, 0):0, (-1, 3):3 }
for test, result in tests.items():
    print 'test: adding', test, '==', result, '---', add(*test) == result

There is no other way to call add, other than manually doing something like add(test[0], test[1]), which is ugly. Also, if there are a variable number of variables, the code could get pretty ugly with all the if-statements you would need.

Another place this is useful is for defining Factory objects (objects that create objects for you). Suppose you have some class Factory, that makes Car objects and returns them. You could make it so that myFactory.make_car('red', 'bmw', '335ix') creates Car('red', 'bmw', '335ix'), then returns it.

def make_car(*args):
    return Car(*args)

This is also useful when you want to call a superclass' constructor.

Monolithic kernel has all kernel services along with kernel core part, thus are heavy and has negative impact on speed and performance. On the other hand micro kernel is lightweight causing increase in performance and speed.
I answered same question at wordpress site. For the difference between monolithic, microkernel and exokernel in tabular form, you can visit here

Sample DF:

8   8  10  14
9   7  14  13

present only those rows where b > 10

In [81]: df[df.b > 10]
Out[81]:
   a   b   c
0  6  11  11
5  5  11   9
7  5  11  10
9  7  14  13

Minimums (for all columns) for the rows satisfying b > 10 condition

In [82]: df[df.b > 10].min()
Out[82]:
a     5
b    11
c     9
dtype: int32

Minimum (for the b column) for the rows satisfying b > 10 condition

In [84]: df.loc[df.b > 10, 'b'].min()
Out[84]: 11

UPDATE: starting from Pandas 0.20.1 the .ix indexer is deprecated, in favor of the more strict .iloc and .loc indexers.

Example: index = False

import pandas as pd

writer = pd.ExcelWriter("dataframe.xlsx", engine='xlsxwriter')
dataframe.to_excel(writer,sheet_name = dataframe, index=False)
writer.save() 

I would prefere

if (!myStr.empty())
{
    //do something
}

Also you don't have to write std::string a = "";. You can just write std::string a; - it will be empty by default

If you have ruby installed

cat FileWithColumnOfNumbers.txt | xargs ruby -e "puts ARGV.map(&:to_i).inject(&:+)"

You could wrap your return value in the Boolean function

Boolean([return value])

That'll ensure all falsey values are false and truthy statements are true.

For oracle:

select( 
select count(*) from foo1 where ID = '00123244552000258'
+
select count(*) from foo2 where ID = '00123244552000258'
+
select count(*) from foo3 where ID = '00123244552000258'
) total from dual;

Why don't you just do this

<a href="yoururl.html"><div>...</div></a>

That should work fine and will prompt the "clickable item" cursor change, which the aforementioned solution will not do.

If you do not care about predictable run time you could try by first splitting your polygons into unions of convex polygons and then pairwise computing the intersection between the sub-polygons.

This would give you a collection of convex polygons such that their union is exactly the intersection of your starting polygons.

Try this:

SELECT * 
  FROM  (
        SELECT neededfield, CONCAT(firstname, ' ', lastname) as firstlast 
        FROM users 
    ) a
WHERE firstlast = "Bob Michael Jones"

There is no direct string compare function in SQL Server

CASE
  WHEN str1 = str2 THEN 0
  WHEN str1 < str2 THEN -1
  WHEN str1 > str2 THEN 1
  ELSE NULL --one of the strings is NULL so won't compare (added on edit)
END

Notes

• you can wraps this via a UDF using CREATE FUNCTION etc
• you may need NULL handling (in my code above, any NULL will report 1)
• str1 and str2 will be column names or @variables

The above process is slow,you can use below method but you need to move collection by collection to another db.

use admin
db.runCommand({renameCollection: "[db_old_name].[collection_name]", to: "[db_new_name].[collection_name]"})

If you are using c# on the desktop, you can use SimpleMapi. That way it will be sent using the default mail client, and the user has the option of reviewing the message before sending, just like mailto:.

To use it you add the Simple-MAPI.NET package (it's 13Kb), and run:

var mapi = new SimpleMapi();
mapi.AddRecipient(null, address, false);
mapi.Attach(path);
//mapi.Logon(ParentForm.Handle);    //not really necessary
mapi.Send(subject, body, true);

Run export DOCKER_CONTENT_TRUST=0 and then try it again.

A lookahead (that (?= part) does not consume any input. It is a zero-width assertion (as are boundary checks and lookbehinds).

You want a regular match here, to consume the cow portion. To capture the portion in between, you use a capturing group (just put the portion of pattern you want to capture inside parenthesis):

cow(.*)milk

No lookaheads are needed at all.

In addition to the above answer I also want to highlight a case of striked out property which really surprised me.

If you are adding a background image to a div :

<div class = "myBackground">

</div>

You want to scale the image to fit in the dimensions of the div so this would be your normal class definition.

.myBackground {

 height:100px;
 width:100px;
 background: url("/img/bck/myImage.jpg") no-repeat; 
 background-size: contain;

}

but if you interchange the order as :-

.myBackground {
 height:100px;
 width:100px;
 background-size: contain;  //before the background
 background: url("/img/bck/myImage.jpg") no-repeat; 
}

then in chrome you ll see background-size as striked out. I am not sure why this is , but yeah you dont want to mess with it.

A javascript method to disable the button itself

document.getElementById("ID NAME").disabled = true;

Once all form fields have satisfied your criteria, you can re-enable the button

Using a Jquery will be something like this

$( "#ID NAME" ).prop( "disabled", true);

According to the git-stash manpage, "A stash is represented as a commit whose tree records the state of the working directory, and its first parent is the commit at HEAD when the stash was created," and git stash show -p gives us "the changes recorded in the stash as a diff between the stashed state and its original parent.

Edit:

A light improvement to this is to use git apply in place of patch:

Alternatively, you can also use git apply -R as a shorthand to git apply --reverse.

I've been finding this really handy lately...

Is the Config/setup.php file actually in /test/content/home/ or is in your document root? it is best to make all references relative to your document root.

include $_SERVER['DOCUMENT_ROOT'] . "Config/setup.php";

Your current code assumes that the location of setup.php is in /text/content/home/Config/setup.php, is this correct?

From within modules of a python package I had to refer to a file that resided in the same directory as package. Ex.

some_dir/
  maincli.py
  top_package/
    __init__.py
    level_one_a/
      __init__.py
      my_lib_a.py
      level_two/
        __init__.py
        hello_world.py
    level_one_b/
      __init__.py
      my_lib_b.py

So in above I had to call maincli.py from my_lib_a.py module knowing that top_package and maincli.py are in the same directory. Here's how I get the path to maincli.py:

import sys
import os
import imp


class ConfigurationException(Exception):
    pass


# inside of my_lib_a.py
def get_maincli_path():
    maincli_path = os.path.abspath(imp.find_module('maincli')[1])
    # top_package = __package__.split('.')[0]
    # mod = sys.modules.get(top_package)
    # modfile = mod.__file__
    # pkg_in_dir = os.path.dirname(os.path.dirname(os.path.abspath(modfile)))
    # maincli_path = os.path.join(pkg_in_dir, 'maincli.py')

    if not os.path.exists(maincli_path):
        err_msg = 'This script expects that "maincli.py" be installed to the '\
        'same directory: "{0}"'.format(maincli_path)
        raise ConfigurationException(err_msg)

    return maincli_path

Based on posting by PlasmaBinturong I modified the code.

Here is a way to solve the problem if your public repo on github.com is working, but your local repo is corrupt. Be aware that you will loose all the commits you've done in the local repo.

Alright, so I have one repo locally that is giving me this object empty error, and the same repo on github.com, but without this error. So what I simply did was to clone the repo that is working from github, and then copied everything from the corrupt repo (except the .git folder), and paste it the cloned repo that is working.

This may not be a practical solution (since you delete the local commits), however, you maintain the code and a repaired version control.

Remember to back-up before applying this approach.

You have deleted migration folder than you are trying to run "update-database" command on Package manager console ? if so

Just manually delete all you tables Than run if update-databse(cons seed data will be deleted)

When using

$("#content").load("content.html");

Then remember that you can not "debug" in chrome locally, because XMLHttpRequest cannot load -- This does NOT mean that it does not work, it just means that you need to test your code on same domain aka. your server

I found this presentation to be very helpfull.

How I Distribute Python applications on Windows - py2exe & InnoSetup

From the site:

There are many deployment options for Python code. I'll share what has worked well for me on Windows, packaging command line tools and services using py2exe and InnoSetup. I'll demonstrate a simple build script which creates windows binaries and an InnoSetup installer in one step. In addition, I'll go over common errors which come up when using py2exe and hints on troubleshooting them. This is a short talk, so there will be a follow-up Open Space session to share experience and help each other solve distribution problems.

the best way is -
1) Sort the both array which are used in first and second loop.
2) if item matched then break the inner loop and hold the index value.
3) when start next iteration start inner loop with hold index value.

After running configure, you can change the config option in the file Modules/Setup as below:

zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz

Or you can uncomment the zlib line as-is.

this will help you , just compare with old if exist , if not then compare with the default value

<select name="select_name">
    @foreach($options as $key => $text)
       <option {{ ($key == old('select_name',$default))?'selected':'' }}> {{ $text }} </option>
    @endforeach
</select>

the $default is the value that injected from the controller to the view

Date.parse() method parses a string representation of a date, and returns the number of milliseconds since January 1, 1970, 00:00:00 UTC.

const unixTimeZero = Date.parse('01 Jan 1970 00:00:00 GMT');
const javaScriptRelease = Date.parse('04 Dec 1995 00:12:00 GMT');

console.log(unixTimeZero);
// expected output: 0

console.log(javaScriptRelease);
// expected output: 818035920000

You can add events to objects when you create them. If you are adding the same events to multiple objects at different times, creating a named function might be the way to go.

var mouseOverHandler = function() {
    // Do stuff
};
var mouseOutHandler = function () {
    // Do stuff
};

$(function() {
    // On the document load, apply to existing elements
    $('select').hover(mouseOverHandler, mouseOutHandler);
});

// This next part would be in the callback from your Ajax call
$("<select></select>")
    .append( /* Your <option>s */ )
    .hover(mouseOverHandler, mouseOutHandler)
    .appendTo( /* Wherever you need the select box */ )
;

Also, you can do this:

FirstClass.this.overridePendingTransition(android.R.anim.slide_in_left, android.R.anim.slide_out_right);

And you don't need to add any animation xml

Not an answer to the very question but perhaps an idea for the underlying task:

When your site logic should not show a certain element, you could insert an invisible "flag" element that you check for.

if condition
    renderElement()
else
    renderElementNotShownFlag() // used by Selenium test

Date has the time part, so we only need to extract it from Date

I personally prefer the default format parameter of the Date when date and time needs to be separated instead of using the extra SimpleDateFormat

Date date = new Date()
String datePart = date.format("dd/MM/yyyy")
String timePart = date.format("HH:mm:ss")

println "datePart : " + datePart + "\ttimePart : " + timePart

You do not need to use substring at all since your format doesn't hold that info.

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String fechaStr = "2013-10-10 10:49:29.10000";  
Date fechaNueva = format.parse(fechaStr);

System.out.println(format.format(fechaNueva)); // Prints 2013-10-10 10:49:29

In short, yes. But there are times when you might favor one vs. the other. Google "case switch vs. if else". There are some discussions already on SO too. Also, here is a good video that talks about it in the context of MATLAB:

http://blogs.mathworks.com/pick/2008/01/02/matlab-basics-switch-case-vs-if-elseif/

Personally, when I have 3 or more cases, I usually just go with case/switch.

I need to code such that if a certain list index exists, then run a function.

You already know how to test for this and in fact are already performing such tests in your code.

The valid indices for a list of length n are 0 through n-1 inclusive.

Thus, a list has an index i if and only if the length of the list is at least i + 1.

subversion will corrupt my project file after a svn up on an almost weekly basis. I'm trying to figure out why it does this right now and came across this problem.

This is somewhat ago but it still might be useful.

My experience shows that resizing the image in-memory before passing it to tesseract sometimes helps.

Try different modes of interpolation. The post https://stackoverflow.com/a/4756906/146003 helped me a lot.

I'd just like to point out something in these answers. In a date/time format string, '/' will be replaced with whatever the user's date separator is, and ':' will be replaced with whatever the user's time separator is. That is, if I've defined my date separator to be '.' (in the Regional and Language Options control panel applet, "intl.cpl"), and my time separator to be '?' (just pretend I'm crazy like that), then

DateTime.Now.ToString("MM/dd/yyyy h:mm tt")

would return

01.05.2009 6?01 PM

In most cases, this is what you want, because you want to respect the user's settings. If, however, you require the format be something specific (say, if it's going to parsed back out by somebody else down the wire), then you need to escape these special characters:

DateTime.Now.ToString("MM\\/dd\\/yyyy h\\:mm tt")

or

DateTime.Now.ToString(@"MM\/dd\/yyyy h\:mm tt")

which would now return

01/05/2009 6:01 PM

EDIT:

Then again, if you really want to respect the user's settings, you should use one of the standard date/time format strings, so that you respect not only the user's choices of separators, but also the general format of the date and/or time.

DateTime.Now.ToShortDateString()
DateTime.Now.ToString("d")

Both would return "1/5/2009" using standard US options, or "05/01/2009" using standard UK options, for instance.

DateTime.Now.ToLongDateString()
DateTime.Now.ToString("D")

Both would return "Monday, January 05, 2009" in US locale, or "05 January 2009" in UK.

DateTime.Now.ToShortTimeString()
DateTime.Now.ToString("t");

"6:01 PM" in US, "18:01" in UK.

DateTime.Now.ToLongTimeString()
DateTime.Now.ToString("T");

"6:01:04 PM" in US, "18:01:04" in UK.

DateTime.Now.ToString()
DateTime.Now.ToString("G");

"1/5/2009 6:01:04 PM" in US, "05/01/2009 18:01:04" in UK.

Many other options are available. See docs for standard date and time format strings and custom date and time format strings.

Off the top of my head, the following are the only built-ins that are subscriptable:

string:  "foobar"[3] == "b"
tuple:   (1,2,3,4)[3] == 4
list:    [1,2,3,4][3] == 4
dict:    {"a":1, "b":2, "c":3}["c"] == 3

But mipadi's answer is correct - any class that implements __getitem__ is subscriptable

In C and C++, the && and || operators "short-circuit". That means that they only evaluate a parameter if required. If the first parameter to && is false, or the first to || is true, the rest will not be evaluated.

The code you posted is safe, though I question why you'd include an empty else block.

My guess about this is this: since the selector is unknown to the compiler, ARC cannot enforce proper memory management.

In fact, there are times when memory management is tied to the name of the method by a specific convention. Specifically, I am thinking of convenience constructors versus make methods; the former return by convention an autoreleased object; the latter a retained object. The convention is based on the names of the selector, so if the compiler does not know the selector, then it cannot enforce the proper memory management rule.

If this is correct, I think that you can safely use your code, provided you make sure that everything is ok as to memory management (e.g., that your methods do not return objects that they allocate).

Do not use rand(); use new C++11 facilities (e.g. std::mt19937, std::uniform_int_distribution, etc.) instead.

You can use code like this (live here on Ideone):

#include <iostream>
#include <random>
using namespace std;

int main()
{
    // Random seed
    random_device rd;

    // Initialize Mersenne Twister pseudo-random number generator
    mt19937 gen(rd());

    // Generate pseudo-random numbers
    // uniformly distributed in range (1, 100)
    uniform_int_distribution<> dis(1, 100);

    // Generate ten pseudo-random numbers
    for (int i = 0; i < 10; i++)
    {
        int randomX = dis(gen);
        cout << "\nRandom X = " << randomX;
    }
}

P.S.

Consider watching this video from Going Native 2013 conference for more details about rand()-related problems:

rand() Considered Harmful

Copy and paste one of the .ts video files into a new tab in Chrome. Remove the identifying number of the .ts file (0,1,2,3 etc. or whatever number it is) and change the extension from ".ts" to ".mp4". That should bring up the video file in your browser as usual.

You can find the thoroughly tested OpenJDK releases provided by Oracle at http://jdk.java.net .

For example, ready to use builds of OpenJDK 10.0.2 from Oracle for 64-bit Linux, MacOS and Windows can be found at http://jdk.java.net/10/ .

Try to convert one of the rows into timestamp using the pd.to_datetime function and then use .map to map the formular to the entire column

You can do it pretty easy in Interface Builder. Just create a view with a table and drop another view onto the table. This will become the table header view. Add your labels and image to that view. See the pic below for the view hierarchy.

Swift is statically typed so the performSelector: methods are to fall by the wayside.

Instead, use GCD to dispatch a suitable block to the relevant queue — in this case it'll presumably be the main queue since it looks like you're doing UIKit work.

EDIT: the relevant performSelector: is also notably missing from the Swift version of the NSRunLoop documentation ("1 Objective-C symbol hidden") so you can't jump straight in with that. With that and its absence from the Swiftified NSObject I'd argue it's pretty clear what Apple is thinking here.

The problem is the Method 'POST' your form is submitting by using the "post" method, and in the AJAX you are using "GET".

Here's how to look in the documentation.

First, you're dealing with IO, so look in the java.io package.

There are two classes that look interesting: FileFilter and FileNameFilter. When I clicked on the first, it showed me that there was a a listFiles() method in the File class. And the documentation for that method says:

Returns an array of abstract pathnames denoting the files in the directory denoted by this abstract pathname.

Scrolling up in the File JavaDoc, I see the constructors. And that's really all I need to be able to create a File instance and call listFiles() on it. Scrolling still further, I can see some information about how files are named in different operating systems.

Some of these answers seem unnecessarily complex. Make your tbody:

display: block; height: 300px; overflow-y: auto

Then manually set the widths of each column so that the thead and tbody columns are the same width. Setting the table's style="table-layout: fixed" may also be necessary.

Regarding the remote option for modals, from the docs:

If a remote URL is provided, content will be loaded via jQuery's load method and injected into the root of the modal element.

That means your remote file should provide the complete modal structure, not just what you want to display on the body.

Bootstrap 3.1 Update:

In v3.1 the above behavior was changed and now the remote content is loaded into .modal-content

See this Demo fiddle

Boostrap 3.3 Update:

This option is deprecated since v3.3.0 and has been removed in v4. We recommend instead using client-side templating or a data binding framework, or calling jQuery.load yourself.

My promisify version of a callback function is the P function:

var P = function() {_x000D_
  var self = this;_x000D_
  var method = arguments[0];_x000D_
  var params = Array.prototype.slice.call(arguments, 1);_x000D_
  return new Promise((resolve, reject) => {_x000D_
    if (method && typeof(method) == 'function') {_x000D_
      params.push(function(err, state) {_x000D_
        if (!err) return resolve(state)_x000D_
        else return reject(err);_x000D_
      });_x000D_
      method.apply(self, params);_x000D_
    } else return reject(new Error('not a function'));_x000D_
  });_x000D_
}_x000D_
var callback = function(par, callback) {_x000D_
  var rnd = Math.floor(Math.random() * 2) + 1;_x000D_
  return rnd > 1 ? callback(null, par) : callback(new Error("trap"));_x000D_
}_x000D_
_x000D_
callback("callback", (err, state) => err ? console.error(err) : console.log(state))_x000D_
callback("callback", (err, state) => err ? console.error(err) : console.log(state))_x000D_
callback("callback", (err, state) => err ? console.error(err) : console.log(state))_x000D_
callback("callback", (err, state) => err ? console.error(err) : console.log(state))_x000D_
_x000D_
P(callback, "promise").then(v => console.log(v)).catch(e => console.error(e))_x000D_
P(callback, "promise").then(v => console.log(v)).catch(e => console.error(e))_x000D_
P(callback, "promise").then(v => console.log(v)).catch(e => console.error(e))_x000D_
P(callback, "promise").then(v => console.log(v)).catch(e => console.error(e))

The P function requires that the callback signature must be callback(error,result).

You'll need to write an insert trigger, and possible an update trigger if you want it to change when the record is changed. This article explains it quite nicely:

http://www.revsys.com/blog/2006/aug/04/automatically-updating-a-timestamp-column-in-postgresql/

CREATE OR REPLACE FUNCTION update_modified_column()   
RETURNS TRIGGER AS $$
BEGIN
    NEW.modified = now();
    RETURN NEW;   
END;
$$ language 'plpgsql';

Apply the trigger like this:

CREATE TRIGGER update_customer_modtime BEFORE UPDATE ON customer FOR EACH ROW EXECUTE PROCEDURE  update_modified_column();

If you set the recovery mode on the database in 2005 (don't know for pre-2005) it will drop the log file all together and then you can put it back in full recovery mode to restart/recreate the logfile. We ran into this with SQL 2005 express in that we couldn't get near the 4GB limit with data until we changed the recovery mode.

As others have stated there is no standard so you should choose one yourself. Here are a couple of things to consider when doing so:

1. If you are using JavaScript to consume JSON then using the same naming convention for properties in both will provide visual consistency and possibly some opportunities for cleaner code re-use.

2. A small reason to avoid kebab-case is that the hyphens may clash visually with - characters that appear in values.

   {
     "bank-balance": -10
   }
   

I've just stumbled over the same problem and found some interesting information and I wanted to put in my two cents and add it here.

First of all, as others have already mentioned, long-running operations should be done by a thread, which can be a background worker, an explicit thread, a thread from the threadpool or (since .Net 4.0) a task: Stackoverflow 570537: update-label-while-processing-in-windows-forms, so that the UI keeps responsive.

But for short tasks there is no real need for threading although it doesn't hurt of course.

I have created a winform with one button and one label to analyze this problem:

System::Void button1_Click(System::Object^  sender, System::EventArgs^  e)
{
  label1->Text = "Start 1";
  label1->Update();
  System::Threading::Thread::Sleep(5000); // do other work
}

My analysis was stepping over the code (using F10) and seeing what happened. And after reading this article Multithreading in WinForms I have found something interesting. The article says at the bottom of the first page, that the UI thread can not repaint the UI until the currently executed function finishes and the window is marked by Windows as "not responding" instead after a while. I have also noticed that on my test application from above while stepping through it, but only in certain cases.

(For the following test it is important to not have Visual Studio set to fullscreen, you must be able to see your little application window at the same time next to it, You must not have to switch between the Visual Studio window for debugging and your application window to see what happens. Start the application, set a breakpoint at label1->Text ..., put the application window beside the VS window and place the mouse cursor over the VS window.)

1. When I click once on VS after app start (to put the focues there and enable stepping) and step through it WITHOUT moving the mouse, the new text is set and the label is updated in the update() function. This means, the UI is repainted obviously.

2. When I step over the first line, then move the mouse around a lot and click somewhere, then step further, the new text is likely set and the update() function is called, but the UI is not updated/repainted and the old text remains there until the button1_click() function finishes. Instead of repainting, the window is marked as "not responsive"! It also doesn't help to add this->Update(); to update the whole form.

3. Adding Application::DoEvents(); gives the UI a chance to update/repaint. Anyway you have to take care that the user can not press buttons or perform other operations on the UI that are not permitted!! Therefore: Try to avoid DoEvents()!, better use threading (which I think is quite simple in .Net).
   But (@Jagd, Apr 2 '10 at 19:25) you can omit .refresh() and .invalidate().

My explanations is as following: AFAIK winform still uses the WINAPI function. Also MSDN article about System.Windows.Forms Control.Update method refers to WINAPI function WM_PAINT. The MSDN article about WM_PAINT states in its first sentence that the WM_PAINT command is only sent by the system when the message queue is empty. But as the message queue is already filled in the 2nd case, it is not send and thus the label and the application form are not repainted.

<>joke> Conclusion: so you just have to keep the user from using the mouse ;-) <>/joke>

$("#yourdropdownid option:selected").text(); // selected option text
$("#yourdropdownid").val(); // selected option value

To Add a Temporary Alias:

1. Goto Terminal (I'm using git bash for windows).
2. Type $ alias gpuom='git push origin master'
3. To See a List of All the aliases type $ alias hit Enter.

To Add a Permanent Alias:

1. Goto Terminal (I'm using git bash for windows).
2. Type $ vim ~/.bashrc and hit Enter (I'm guessing you are familiar with vim).
3. Add your new aliases (For reference look at the snippet below).

   #My custom aliases  
   alias gpuom='git push origin master' 
   alias gplom='git pull origin master'
   

4. Save and Exit (Press Esc then type :wq).
5. To See a List of All the aliases type $ alias hit Enter.

You have to catch the error just as you're already doing for your save() call and since you're handling multiple errors here, you can try multiple calls sequentially in a single do-catch block, like so:

func deleteAccountDetail() {
    let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
    let request = NSFetchRequest()
    request.entity = entityDescription

    do {
        let fetchedEntities = try self.Context!.executeFetchRequest(request) as! [AccountDetail]

        for entity in fetchedEntities {
            self.Context!.deleteObject(entity)
        }

        try self.Context!.save()
    } catch {
        print(error)
    }
}

Or as @bames53 pointed out in the comments below, it is often better practice not to catch the error where it was thrown. You can mark the method as throws then try to call the method. For example:

func deleteAccountDetail() throws {
    let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
    let request = NSFetchRequest()

    request.entity = entityDescription

    let fetchedEntities = try Context.executeFetchRequest(request) as! [AccountDetail]

    for entity in fetchedEntities {
        self.Context!.deleteObject(entity)
    }

    try self.Context!.save()
}

I faced the same problem and I've found a pretty clean solution: After Html.fromHtml() you can run an AsyncTask that iterates over all the tags, fetches the images and then displays them.

Here you can find some code that you can use (but it needs some customization): https://gist.github.com/1190397

This should do it for you.

<div id="nav-wrap">
    <ul id="nav">
        <li><a href="#">Link</a></li>
        <li><a href="#">Link</a></li>
        <li><a href="#">Link</a></li>
        <li><a href="#">Link</a></li>
        <li><a href="#">Link</a></li>
        <li><a href="#">Link</a></li>
    </ul>
</div>

#nav-wrap {
    float: left;
    height: 87px;
    width: 900px;
}

#nav {
    display: inline;
    height: 87px;
    width: 100%;
}

.nav-item {
    float: left;
    height: 87px;
    line-height: 87px;
    text-align: center;
    text-decoration: none;
    width: 150px;

}

Please try the below Code

It's worth mentioning that the method Html.fromHtml(String source) is deprecated as of API level 24. If that's your target API, you should use Html.fromHtml(String source, int flags) instead.

The python shutil.copytree method its a mess. I've done one that works correctly:

def copydirectorykut(src, dst):
    os.chdir(dst)
    list=os.listdir(src)
    nom= src+'.txt'
    fitx= open(nom, 'w')

    for item in list:
        fitx.write("%s\n" % item)
    fitx.close()

    f = open(nom,'r')
    for line in f.readlines():
        if "." in line:
            shutil.copy(src+'/'+line[:-1],dst+'/'+line[:-1])
        else:
            if not os.path.exists(dst+'/'+line[:-1]):
                os.makedirs(dst+'/'+line[:-1])
                copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
            copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
    f.close()
    os.remove(nom)
    os.chdir('..')

It does what you ask, SELECT 1 FROM table will SELECT (return) a 1 for every row in that table, if there were 3 rows in the table you would get

1
1
1

Take a look at Count(*) vs Count(1) which may be the issue you were described.

W3C's recommendation:

If designing a form or database that will accept names from people with a variety of backgrounds, you should ask yourself whether you really need to have separate fields for given name and family name.

… Bear in mind that names in some cultures can be quite a lot longer than your own. … Avoid limiting the field size for names in your database. In particular, do not assume that a four-character Japanese name in UTF-8 will fit in four bytes – you are likely to actually need 12.

https://www.w3.org/International/questions/qa-personal-names

For database fields, VARCHAR(255) is a safe default choice, unless you can actually come up with a good reason to use something else. For typical web applications, performance won't be a problem. Don't prematurely optimize.

template <typename T> bool IsInVector(const T & what, const std::vector<T> & vec)
{
    return std::find(vec.begin(),vec.end(),what)!=vec.end();
}

This is commonly caused by running out of file descriptors.

There is the systems total file descriptor limit, what do you get from the command:

sysctl fs.file-nr

This returns counts of file descriptors:

<in_use> <unused_but_allocated> <maximum>

To find out what a users file descriptor limit is run the commands:

sudo su - <username>
ulimit -Hn

To find out how many file descriptors are in use by a user run the command:

sudo lsof -u <username> 2>/dev/null | wc -l

So now if you are having a system file descriptor limit issue you will need to edit your /etc/sysctl.conf file and add, or modify it it already exists, a line with fs.file-max and set it to a value large enough to deal with the number of file descriptors you need and reboot.

fs.file-max = 204708

Yes there is, you can simply put <hr> in your code where you want it, I already use it in one of my admin panel side bar.

If the view item performs the same operation, you can use the @+id for each entry in any layout because during the compilation of multiple @+id/foo the R.java file only creates one enumeration. So for example, if I have a save button on each page that performs the same operation, I use android:id="@+id/button_save" in each layout. The R.java file only has one entry for the button_save.

private bool CheckAll()
{
    if ( ....)
    {
        return true;
    }

    return false;
}

When the if-condition is false the method doesn't know what value should be returned (you probably get an error like "not all paths return a value").

As CQQL pointed out if you mean to return true when your if-condition is true you could have simply written:

private bool CheckAll()
{
    return (your_condition);
}

If you have side effects, and you want to handle them before you return, the first (long) version would be required.

Look for define in system/core/CodeIgniter.php:

define('CI_VERSION', '3.1.8');

With new pandas version, it is easy to get as dataframe

unique_count = pd.groupby(['YEARMONTH'], as_index=False).agg(uniq_CLIENTCODE =('CLIENTCODE',pd.Series.count))

GCC compilers always try to compile your program if this is at all possible. However, in some cases, the C and C++ standards specify that certain extensions are forbidden. Conforming compilers such as gcc or g++ must issue a diagnostic when these extensions are encountered. For example, the gcc compiler’s -pedantic option causes gcc to issue warnings in such cases. Using the stricter -pedantic-errors option converts such diagnostic warnings into errors that will cause compilation to fail at such points. Only those non-ISO constructs that are required to be flagged by a conforming compiler will generate warnings or errors.

I have worked with SAP since 1998. SAP is a type of software called ERP (Enterprise Resource Planning) that large companies use to manage their day to day affairs. On the macro, the software can be split into two categories: Technical and Functional

Let's go Technical first, as it answers the "What is ABAP" part of your question.

Technical

There are two technical "stacks" within the SAP software, the first is the ABAP stack which is inclusive of all the original technology that SAP was. ABAP is the proprietary coding language for SAP to develop RICEFW objects (Reports, Interfaces, Conversions, Extensions, Forms and Workflows) within the ABAP stack.

The ABAP stack is traditionally navigated via Transaction Codes (T-Codes) to take you to different screens within the SAP Environment. From a technical perspective, you will do all of your performance and tuning of the WORK PROCESSES in the SAP system here, as well as configuring all of the system RFCs, building user profiles and also doing the necessary interfacing between the OS (usually Windows or HPUX) and the Oracle Database (currently Enterprise 11g).

The JAVA stack controls the "Netweaver" aspect of SAP which encapsulates SAP's ability to be accessed via the Internet via SAP Portal and it's ability to interface with other SAP and non-SAP legacy systems via Process Integration (PI).

SAP also has extensive capabilities in the Business Intelligence Field (BI) by accessing information stored within the Business Warehouse (BW). Currently, there is a new technology called HANA 1.0 that compresses the time to run reports against these repositories.

There are two primarily technologists that run ALL of these functions, they are called SAP Basis (Netweaver) Administrators and ABAP Developers.

Functional

SAP has specific pre-populated functional packages for different business areas. For example, Exxon runs the "IS Oil & Gas" package while Bank of America runs the "Banking" package, while further still Lockheed Martin runs the "Aerospace & Defense" package. These packages were developed over time by the amalgamation of intelligent functional customizations that could be intelligently ported to the system via inclusion in dot releases.

However, there are some vanilla functional modules that almost all entities run, regardless of their specific industry:

• HR: Human Resources
• PM: Project Management
• FI: Financial
• CO: Controllers
• MM: Materials Management
• SD: Sales and Distribution
• PP: Production Planning

and finally the biggie:

• MDM: Master Data Management which encapsulates the data for customer/vendor/material etc.

there are two way:

First :

Inside your CD of SQL Server 2012

you can go to this path \redist\VisualStudioShell.

And you most install this file VS10sp1-KB983509.msp.

After several minutes your problem fix.

Restart your computer and then fire SetUp of SQL Server 2012.

See this picture.

Secound :

But if you want download online Service Pack 1 view This Link

And press download.

After download run this exe file and let it download and fix your VS2010 to VS2010 SP1.

And then restart your windows.

After this operation you can install SQL Server 2012

Another solution using DataFrame.apply(), with slightly less typing and more scalable when you want to join more columns:

cols = ['foo', 'bar', 'new']
df['combined'] = df[cols].apply(lambda row: '_'.join(row.values.astype(str)), axis=1)

If you need to load JSON from another domain: http://en.wikipedia.org/wiki/JSONP
However be aware of potential XSSI attacks: https://www.scip.ch/en/?labs.20160414

If it's the same domain so just use Ajax.

Simple Java Program which connects to the SQL Server.

NOTE: You need to add sqljdbc.jar into the build path

// localhost : local computer acts as a server

// 1433 : SQL default port number

// username : sa

// password: use password, which is used at the time of installing SQL server management studio, In my case, it is 'root'

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

    public class Conn {
        public static void main(String[] args) throws InstantiationException, IllegalAccessException, ClassNotFoundException {

            Connection conn=null;
            try {
                Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
                conn = DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=company", "sa", "root");

                if(conn!=null)
                    System.out.println("Database Successfully connected");

            } catch (SQLException e) {
                e.printStackTrace();
            }

        }
    }

You should be able to do the count on the purch variable:

purch.Count();

e.g.

var purch = from purchase in myBlaContext.purchases
select purchase;

purch.Count();

In this Question, best answer not work for me. After that i found this method to show listview footer,

LayoutInflater inflater = getLayoutInflater();
ViewGroup footerView = (ViewGroup)inflater.inflate(R.layout.footer_layout,listView,false);
listView.addFooterView(footerView, null, false);

And create new layout call footer_layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <TextView
        android:id="@+id/tv"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Done"
        android:textStyle="italic"
        android:background="#d6cf55"
        android:padding="10dp"/>
</LinearLayout>

If not work refer this article hear

Another way of doing it is a single listener from activity , like this:

public class MyActivity extends Activity implements OnClickListener {
    .......  code

    //my listener
    @Override
    public void onClick(View v) {
        if (v.getId() == R.id.mybutton) { 
            DoSomething();
            return;
        }

        if (v.getId() == R.id.mybutton2) { 
            DoSomething2();
            return;
        }
    }
}

I Like to do it with single IF instead of switch-else, but if you prefer that, then you should do:

//my listener
@Override
public void onClick(View v) {
    switch(v.getId()) {
        case R.id.mybutton:
        { 
             DoSomething();
             break;
        }

        case R.id.mybutton2:

Having reviewed a few different large scale React/Redux projects in my experience Sagas provide developers a more structured way of writing code that is much easier to test and harder to get wrong.

Yes it is a little wierd to start with, but most devs get enough of an understanding of it in a day. I always tell people to not worry about what yield does to start with and that once you write a couple of test it will come to you.

I have seen a couple of projects where thunks have been treated as if they are controllers from the MVC patten and this quickly becomes an unmaintable mess.

My advice is to use Sagas where you need A triggers B type stuff relating to a single event. For anything that could cut across a number of actions, I find it is simpler to write customer middleware and use the meta property of an FSA action to trigger it.

This should help clear up any questions you may have: C# literals

Here is a table from the linked content:

Regular literal	Verbatim literal	Resulting string
"Hello"	@"Hello"	Hello
"Backslash: \\"	@"Backslash: \"	Backslash: \
"Quote: \""	@"Quote: """	Quote: "
"CRLF:\r\nPost CRLF"	@"CRLF: Post CRLF"	CRLF: Post CRLF

@DRapp is a genius. I never understood how he coded his SQL,so I tried coding it in my own understanding.

    SELECT 
      f.username,
      f.point,
      f.avg_time
    FROM
      (
      SELECT
        userscores.username,
        userscores.point,
        userscores.avg_time
      FROM
        (
        SELECT
          users.username,
          scores.point,
          scores.avg_time
        FROM
          scores
        JOIN users
        ON scores.user_id = users.id
        ORDER BY scores.point DESC
        ) userscores
      ORDER BY
        point DESC,
        avg_time
      ) f
    GROUP BY f.username
    ORDER BY point DESC

It yields the same result by using GROUP BY instead of the user @variables.

I know this is an old post but I've just signed up for Azure and I get 25,000 emails a month for free via SendGrid. These instructions are excellent, I was up and running in minutes:

To offer an update on the situation on Q2 of 2017.

A new CSS3 display property is available in Firefox 53, Chrome 58 and Opera 45.

.clearfix {
   display: flow-root;
}

Check the availability for any browser here: http://caniuse.com/#feat=flow-root

The element (with a display property set to flow-root) generates a block container box, and lays out its contents using flow layout. It always establishes a new block formatting context for its contents.

Meaning that if you use a parent div containing one or several floating children, this property is going to ensure the parent encloses all of its children. Without any need for a clearfix hack. On any children, nor even a last dummy element (if you were using the clearfix variant with :before on the last children).

.container {_x000D_
  display: flow-root;_x000D_
  background-color: Gainsboro;_x000D_
}_x000D_
_x000D_
.item {_x000D_
  border: 1px solid Black;_x000D_
  float: left;_x000D_
}_x000D_
_x000D_
.item1 {  _x000D_
  height: 120px;_x000D_
  width: 120px;_x000D_
}_x000D_
_x000D_
.item2 {  _x000D_
  height: 80px;_x000D_
  width: 140px;_x000D_
  float: right;_x000D_
}_x000D_
_x000D_
.item3 {  _x000D_
  height: 160px;_x000D_
  width: 110px;_x000D_
}

<div class="container">_x000D_
  This container box encloses all of its floating children._x000D_
  <div class="item item1">Floating box 1</div>_x000D_
  <div class="item item2">Floating box 2</div> _x000D_
  <div class="item item3">Floating box 3</div>  _x000D_
</div>

The simplest and most efficient way is to perform this command:

data.Length--;

by doing this you move the pointer (i.e. last index) back one character but you don't change the mutability of the object. In fact, clearing a StringBuilder is best done with Length as well (but do actually use the Clear() method for clarity instead because that's what its implementation looks like):

data.Length = 0;

again, because it doesn't change the allocation table. Think of it like saying, I don't want to recognize these bytes anymore. Now, even when calling ToString(), it won't recognize anything past its Length, well, it can't. It's a mutable object that allocates more space than what you provide it, it's simply built this way.

put the logic in

afterTextChanged(Editable s) {
    string str = s.toString()
    // use the string str
}

documentation on TextWatcher

emplace_back conforming implementation will forward arguments to the vector<Object>::value_typeconstructor when added to the vector. I recall Visual Studio didn't support variadic templates, but with variadic templates will be supported in Visual Studio 2013 RC, so I guess a conforming signature will be added.

With emplace_back, if you forward the arguments directly to vector<Object>::value_type constructor, you don't need a type to be movable or copyable for emplace_back function, strictly speaking. In the vector<NonCopyableNonMovableObject> case, this is not useful, since vector<Object>::value_type needs a copyable or movable type to grow.

But note that this could be useful for std::map<Key, NonCopyableNonMovableObject>, since once you allocate an entry in the map, it doesn't need to be moved or copied ever anymore, unlike with vector, meaning that you can use std::map effectively with a mapped type that is neither copyable nor movable.

The one above only runs for "One File" only, but you can also run this for multiple files within your folder:

Get-ChildItem 'C:yourfile*.xml' -Recurse | ForEach {
     (Get-Content $_ | ForEach  { $_ -replace '[MYID]', 'MyValue' }) |
     Set-Content $_
}

There are right answers but I just want to add one more option (requires downtime):

1. Stop Redis.
2. Delete RDB file (find location in redis.conf).
3. Start Redis.

This will work for generating a number 1 - 10. Make sure you import Random at the top of your code.

import java.util.Random;

If you want to test it out try something like this.

Random rn = new Random();

for(int i =0; i < 100; i++)
{
    int answer = rn.nextInt(10) + 1;
    System.out.println(answer);
}

Also if you change the number in parenthesis it will create a random number from 0 to that number -1 (unless you add one of course like you have then it will be from 1 to the number you've entered).

This function creates date from timestamp:

    function formatDateTime(dateString) {
        const parsed = moment(new Date(dateString))

        if (!parsed.isValid()) {
            return dateString
        }

        return parsed.format('MMM D, YYYY, HH:mmA')
    }

It's quite unpractical to make multiple select with size 1. think about it. I made a fiddle here: https://jsfiddle.net/wqd0yd5m/2/

<select name="test" multiple>
    <option>123</option>
    <option>456</option>
    <option>789</option>
</select>

Try to explore other options such as using checkboxes to achieve your goal.

It's a Xcode bug (Xcode 8.2.1) and I've reported that to Apple, it will happen when you have a large dictionary literal or a nested dictionary literal. You have to break your dictionary to smaller parts and add them with append method until Apple fixes the bug.

try this code

in example code use axios get rest API.

in mounted

  mounted(){
    var config = {
    headers: { 
      'x-rapidapi-host': 'covid-19-coronavirus-statistics.p.rapidapi.com',

      }
   };
   axios.get('https://covid-19-coronavirus-statistics.p.rapidapi.com/v1/stats? 
    country=Thailand',  config)
    .then((response) => {
    console.log(response.data);
  });
}

Hope is help.

Using Python a lot, I find myself needing frequently needing to shift blocks by more than one indent. You can do this by using any of the block selection methods, and then just enter the number of indents you wish to jump right before the >

For example, V5j3> will indent five lines three times - which is 12 spaces if you use four spaces for indents.

My take here, based on the pitfalls of convention over configuration:

My issue with Maven is the difficulty in discovery and limitless complexity. That, and watching colleagues waste half a work day day fighting Maven build issues. Also IMHO, the Maven integration with Eclipse makes things worse, because you have multiplied the number of places where things go wrong.

The difference between those will depend largely on what browser you are currently referring to. Each one implements these properties differently, or not at all. Quirksmode has great documentation regarding browser differences in regards to W3C standards like the DOM and JavaScript Events.

I would use specific user (and NOT Application user). Then I will enable impersonation in the application. Once you do that whatever account is set as the specific user, those credentials would used to access local resources on that server (Not for external resources).

Specific User setting is specifically meant for accessing local resources.

You can use instance_of?

e.g

@some_var.instance_of?(Hash)

Check local history in your IDE.

Try this:

 DatePicker datePicker = (DatePicker) findViewById(R.id.datePicker1);
 int day = datePicker.getDayOfMonth();
 int month = datePicker.getMonth() + 1;
 int year = datePicker.getYear();

Another issue is that you're reading with scanf("%f", &input); only. If the user types something that can't be interpreted as a C floating-point number, like "pi", the scanf() call will not assign anything to input, and won't progress from there. This means it would attempt to keep reading "pi", and failing.

Given the change to while(!feof(stdin)) which other posters are correctly recommending, if you typed "pi" in there would be an endless loop of printing out the former value of input and printing the prompt, but the program would never process any new input.

scanf() returns the number of assignments to input variables it made. If it made no assignment, that means it didn't find a floating-point number, and you should read through more input with something like char string[100];scanf("%99s", string);. This will remove the next string from the input stream (up to 99 characters, anyway - the extra char is for the null terminator on the string).

You know, this is reminding me of all the reasons I hate scanf(), and why I use fgets() instead and then maybe parse it using sscanf().

Here is a shell script that uses Awk's gsub function to replace the text you're searching for with the proper escape sequence to display it in bright red:

#! /bin/bash
awk -vstr=$1 'BEGIN{repltext=sprintf("%c[1;31;40m&%c[0m", 0x1B,0x1B);}{gsub(str,repltext); print}' $2

Use it like so:

$ ./cgrep pattern [file]

Unfortunately, it doesn't have all the functionality of grep.

Delete Temp files by run > %temp%

And Open VS2015 by run as admin,

it works for me.

Try to run it as:

python3 -m p_03_using_bisection_search

You need an IP-address-based reverse geocoding API... like the one from ipdata.co. I'm sure there are plenty of options available.

You may want to allow the user to override this, however. For example, they could be on a corporate VPN which makes the IP address look like it's in a different country.

fileExists() is a method of FileSystemObject, not a global scope function.

You also have an issue with the delete, DeleteFile() is also a method of FileSystemObject.

Furthermore, it seems you are moving the file and then attempting to deal with the overwrite issue, which is out of order. First you must detect the name collision, so you can choose the rename the file or delete the collision first. I am assuming for some reason you want to keep deleting the new files until you get to the last one, which seemed implied in your question.

So you could use the block:

if NOT fso.FileExists(newname) Then  

    file.move fso.buildpath(OUT_PATH, newname)           

else

    fso.DeleteFile newname
    file.move fso.buildpath(OUT_PATH, newname)  

end if 

Also be careful that your string comparison with the = sign is case sensitive. Use strCmp with vbText compare option for case insensitive string comparison.

Tried your example

from . import config

got the following SystemError:
/usr/bin/python3.4 test.py
Traceback (most recent call last):
File "test.py", line 1, in
from . import config
SystemError: Parent module '' not loaded, cannot perform relative import

This will work for me:

import config
print('debug=%s'%config.debug)

>>>debug=True

Tested with Python:3.4.2 - PyCharm 2016.3.2

Beside this PyCharm offers you to Import this name.
You hav to click on config and a help icon appears.

You are checking whether the string contains all illegal characters. Change the ||s to &&s.

select * from my_table where my_field Like '[a-z][a-z]%'

Try

sudo <path to mysql>/support-files/mysql.server start
sudo <path to mysql>/support-files/mysql.server stop

Else try:

sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
sudo /Library/StartupItems/MySQLCOM/MySQLCOM stop<br>
sudo /Library/StartupItems/MySQLCOM/MySQLCOM restart

However, I found that the second option only worked (OS X 10.6, MySQL 5.1.50) if the .plist has been loaded with:

sudo launchctl load -w /Library/LaunchDaemons/com.mysql.mysqld.plist

PS: I also found that I needed to unload the .plist to get an unrelated install of MAMP-MySQL to start / stop correctly. After running running this, MAMP-MySQL starts just fine:

sudo launchctl unload -w /Library/LaunchDaemons/com.mysql.mysqld.plist

Download file

For downloading you can use multiple ways as been explained above, moreover I will also provide my strategy for this scenario.

1. npm install --save react-download-link
2. import DownloadLink from "react-download-link";
3. React download link for client side cache data

   <DownloadLink 
       label="Download" 
       filename="fileName.txt"
       exportFile={() => "Client side cache data here…"}
   />
   

4. Download link for client side cache data with Promises

   <DownloadLink
       label="Download with Promise"
       filename="fileName.txt"
       exportFile={() => Promise.resolve("cached data here …")}
   />
   

5. Download link for data from URL with Promises Function to Fetch data from URL

    getDataFromURL = (url) => new Promise((resolve, reject) => {
       setTimeout(() => {
           fetch(url)
               .then(response => response.text())
               .then(data => {
                   resolve(data)
               });
       });
   }, 2000);
   

6. DownloadLink component calling Fetch function

   <DownloadLink
         label=”Download”
         filename=”filename.txt”
         exportFile={() => Promise.resolve(this. getDataFromURL (url))}
   />
   

Happy coding! ;)

Installing mysqlclient using anaconda is pretty simple and straight forward.

conda install -c bioconda mysqlclient

and then, install pymysql using pip.

pip install pymysql

happy learning..

I ran into the same problem. I use jdk 1.8 and maven 3.3.9 Once I export JAVA_HOME, I did not see this error. export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/

I am using API level 27 and found a best solution after struggling for around two days. If you want to read a xml file from a class which doesn't derive from Activity or Application then do the following.

1. Put the testdata.xml file inside the assets directory.

2. Write the following code to get the testdata document parsed.

       InputStream inputStream = this.getClass().getResourceAsStream("/assets/testdata.xml");
   
       // create a new DocumentBuilderFactory
       DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
       // use the factory to create a documentbuilder
       DocumentBuilder builder = factory.newDocumentBuilder();
       // create a new document from input stream
       Document doc = builder.parse(inputStream);
   

Also nice to know...
Pointer-events can be disabled for a parent element (probably transparent div) and yet be enabled for child elements. This is helpful if you work with multiple overlapping div layers, where you want to be able click the child elements of any layer. For this all parenting divs get pointer-events: none and click-children get pointer-events reenabled by pointer-events: all

.parent {
    pointer-events:none;        
}
.child {
    pointer-events:all;
}

<div class="some-container">
   <ul class="layer-0 parent">
     <li class="click-me child"></li>
     <li class="click-me child"></li>
   </ul>

   <ul class="layer-1 parent">
     <li class="click-me-also child"></li>
     <li class="click-me-also child"></li>
   </ul>
</div>

On a recent project built using Bootstrap 4, I had tried all of the above methods but nothing worked. My approach was by editing the library CSS using jQuery to get 100% on the table.

 // * Select2 4.0.7

$('.select2-multiple').select2({
    // theme: 'bootstrap4', //Doesn't work
    // width:'100%', //Doesn't work
    width: 'resolve'
});

//The Fix
$('.select2-w-100').parent().find('span')
    .removeClass('select2-container')
    .css("width", "100%")
    .css("flex-grow", "1")
    .css("box-sizing", "border-box")
    .css("display", "inline-block")
    .css("margin", "0")
    .css("position", "relative")
    .css("vertical-align", "middle")

Use these few simple commands:

mysqldump -u username -p -v olddatabase > olddbdump.sql
mysqladmin -u username -p create newdatabase
mysql -u username -p newdatabase < olddbdump.sql

Or to reduce I/O use the following as suggested by @Pablo Marin-Garcia:

mysqladmin -u username -p create newdatabase
mysqldump -u username -v olddatabase -p | mysql -u username -p -D newdatabase

If you want to know the number of tables that belong to a certain schema/user, you can also use SQL similar to this one:

SELECT Count(*) FROM DBA_TABLES where OWNER like 'PART_OF_NAME%';

$(document).ready(function() {

  //calculate the window height & add css properties for height 100%

  wh = $( window ).height();

  ww = $( window ).width();

I found that "phpseclib" should help you with this (SFTP and many more features). http://phpseclib.sourceforge.net/

To Put the file to the server, simply call (Code example from http://phpseclib.sourceforge.net/sftp/examples.html#put)

<?php
include('Net/SFTP.php');

$sftp = new Net_SFTP('www.domain.tld');
if (!$sftp->login('username', 'password')) {
    exit('Login Failed');
}

// puts a three-byte file named filename.remote on the SFTP server
$sftp->put('filename.remote', 'xxx');
// puts an x-byte file named filename.remote on the SFTP server,
// where x is the size of filename.local
$sftp->put('filename.remote', 'filename.local', NET_SFTP_LOCAL_FILE);

The $@ and $< are special macros.

Where:

$@ is the file name of the target.

$< is the name of the first dependency.

the simplest way to copy a List is to pass it to the constructor of the new list:

List<String> b = new ArrayList<>(a);

b will be a shallow copy of a

Looking at the source of Collections.copy(List,List) (I'd never seen it before) it seems to be for coping the elements index by index. using List.set(int,E) thus element 0 will over write element 0 in the target list etc etc. Not particularly clear from the javadocs I'd have to admit.

List<String> a = new ArrayList<>(a);
a.add("foo");
b.add("bar");

List<String> b = new ArrayList<>(a); // shallow copy 'a'

// the following will all hold
assert a.get(0) == b.get(0);
assert a.get(1) == b.get(1);
assert a.equals(b);
assert a != b; // 'a' is not the same object as 'b'

To replace anything that starts with "text" until the last character:

text.+(.*)$

Example

text             hsjh sdjh sd          jhsjhsdjhsdj hsd
                                                      ^
                                                      last character

text.+(\ 123)

Example

text fuhfh283nfnd03no3 d90d3nd 3d 123 udauhdah au dauh ej2e
^                                   ^
From here                     To here

try this with sql2012 or above,

You can use ClosedXML for this.

Store your table in a DataTable and you can export the table to excel by this simple snippet:

XLWorkbook workbook = new XLWorkbook();
DataTable table = GetYourTable();
workbook.Worksheets.Add(table );

You can read the documentation of ClosedXML to learn more. Hope this helps!

I wrote a blog entry about this, as I encountered this maddening problem, and finally yanked my system back into working order.

These are the things to check, in this order:

1. Check your properties options in your linker settings at: Properties > Configuration Properties > Linker > Advanced > Target Machine. Select MachineX64 if you are targeting a 64 bit build, or MachineX86 if you are making a 32 bit build.

2. Select Build > Configuration Manager from the main menu in visual studio. Make sure your project has the correct platform specified. It is possible for the IDE to be set to build x64 but an individual project in the solution can be set to target win32. So yeah, visual studio leaves a lot of rope to hang yourself, but that's life.

3. Check your library files that they really are of the type of platform are targeting. This can be used by using dumpbin.exe which is in your visual studio VC\bin directory. use the -headers option to dump all your functions. Look for the machine entry for each function. it should include x64 if it's a 64 bit build.

4. In visual studio, select Tools > Options from the main menu. select Projects and Solutions > VC++ Directories. Select x64 from the Platform dropdown. Make sure that the first entry is: $(VCInstallDir)\bin\x86_amd64 followed by $(VCInstallDir)\bin.

Once I did step 4 everything worked again for me. The thing was I was encountering this problem on all my projects where I wanted to compile towards a 64 bit target.

What I believe you're looking for is a way to work with arrays as object values:

var o = {} // empty Object
var key = 'Orientation Sensor';
o[key] = []; // empty Array, which you can push() values into


var data = {
    sampleTime: '1450632410296',
    data: '76.36731:3.4651554:0.5665419'
};
var data2 = {
    sampleTime: '1450632410296',
    data: '78.15431:0.5247617:-0.20050584'
};
o[key].push(data);
o[key].push(data2);

This is standard JavaScript and not something NodeJS specific. In order to serialize it to a JSON string you can use the native JSON.stringify:

JSON.stringify(o);
//> '{"Orientation Sensor":[{"sampleTime":"1450632410296","data":"76.36731:3.4651554:0.5665419"},{"sampleTime":"1450632410296","data":"78.15431:0.5247617:-0.20050584"}]}'

http://en.wikipedia.org/wiki/Hexspeak
http://www.urbandictionary.com/define.php?term=dead%3Abeef

"Dead beef" is a very popular sentence in programming, because it is built only from letters a-f, which are used in hexadecimal notation. Colons in the beginning and in the middle of the sentence make this sentence a (theoretically) valid IPv6 address.

If none of the above solution worked for you, locate the Wifi adapter from "Control Panel\Network and Internet\Network Connections", right click on it, and select "Diagnose", then follow the given instructions on the screen. It worked for me.

This should work:

Uri selectedUri = Uri.parse(Environment.getExternalStorageDirectory() + "/myFolder/");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(selectedUri, "resource/folder");

if (intent.resolveActivityInfo(getPackageManager(), 0) != null)
{
    startActivity(intent);
}
else
{
    // if you reach this place, it means there is no any file 
    // explorer app installed on your device
}

Please, be sure that you have any file explorer app installed on your device.

EDIT: added a shantanu's recommendation from the comment.

LIBRARIES: You can also have a look at the following libraries https://android-arsenal.com/tag/35 if the current solution doesn't help you.

>>> test
array([[0, 1, 2, 3, 4],
       [5, 6, 7, 8, 9]])

>>> ncol = test.shape[1]
>>> ncol
5L

Then you can select the 2nd - 4th column this way:

>>> test[0:, 1:(ncol - 1)]
array([[1, 2, 3],
       [6, 7, 8]])

The usual method I have seen is X.Y.Z, which generally corresponds to major.minor.patch:

• Major version numbers change whenever there is some significant change being introduced. For example, a large or potentially backward-incompatible change to a software package.
• Minor version numbers change when a new, minor feature is introduced or when a set of smaller features is rolled out.
• Patch numbers change when a new build of the software is released to customers. This is normally for small bug-fixes or the like.

Other variations use build numbers as an additional identifier. So you may have a large number for X.Y.Z.build if you have many revisions that are tested between releases. I use a couple of packages that are identified by year/month or year/release. Thus, a release in the month of September of 2010 might be 2010.9 or 2010.3 for the 3rd release of this year.

There are many variants to versioning. It all boils down to personal preference.

For the "1.3v1.1", that may be two different internal products, something that would be a shared library / codebase that is rev'd differently from the main product; that may indicate version 1.3 for the main product, and version 1.1 of the internal library / package.

Well, for one thing your epression can be simplified:

$("#pDetails").attr("style")

since there should only be one element for any given ID and the ID selector will be much faster than the attribute id selector you're using.

If you just want to return the display value or something, use css():

$("#pDetails").css("display")

If you want to search for elements that have display none, that's a lot harder to do reliably. This is a rough example that won't be 100%:

$("[style*='display: none']")

but if you just want to find things that are hidden, use this:

$(":hidden")

First, your JSON has nested objects, so it normally cannot be directly converted to CSV. You need to change that to something like this:

{
    "pk": 22,
    "model": "auth.permission",
    "codename": "add_logentry",
    "content_type": 8,
    "name": "Can add log entry"
},
......]

Here is my code to generate CSV from that:

import csv
import json

x = """[
    {
        "pk": 22,
        "model": "auth.permission",
        "fields": {
            "codename": "add_logentry",
            "name": "Can add log entry",
            "content_type": 8
        }
    },
    {
        "pk": 23,
        "model": "auth.permission",
        "fields": {
            "codename": "change_logentry",
            "name": "Can change log entry",
            "content_type": 8
        }
    },
    {
        "pk": 24,
        "model": "auth.permission",
        "fields": {
            "codename": "delete_logentry",
            "name": "Can delete log entry",
            "content_type": 8
        }
    }
]"""

x = json.loads(x)

f = csv.writer(open("test.csv", "wb+"))

# Write CSV Header, If you dont need that, remove this line
f.writerow(["pk", "model", "codename", "name", "content_type"])

for x in x:
    f.writerow([x["pk"],
                x["model"],
                x["fields"]["codename"],
                x["fields"]["name"],
                x["fields"]["content_type"]])

You will get output as:

pk,model,codename,name,content_type
22,auth.permission,add_logentry,Can add log entry,8
23,auth.permission,change_logentry,Can change log entry,8
24,auth.permission,delete_logentry,Can delete log entry,8

I personally wouldn't try grabbing it inside of the view. I'm not amazing at Laravel, but I would imagine you'd need to send your route to a controller, and then within the controller, pass the variable (via an array) into your view, using something like $url = Request::url();.

One way of doing it anyway.

EDIT: Actually look at the method above, probably a better way.

You can use INSERT... IGNORE syntax if you want to take no action when there's a duplicate record.

You can use REPLACE INTO syntax if you want to overwrite an old record with a new one with the same key.

Or, you can use INSERT... ON DUPLICATE KEY UPDATE syntax if you want to perform an update to the record instead when you encounter a duplicate.

Edit: Thought I'd add some examples.

Examples

Say you have a table named tbl with two columns, id and value. There is one entry, id=1 and value=1. If you run the following statements:

REPLACE INTO tbl VALUES(1,50);

You still have one record, with id=1 value=50. Note that the whole record was DELETED first however, and then re-inserted. Then:

INSERT IGNORE INTO tbl VALUES (1,10);

The operation executes successfully, but nothing is inserted. You still have id=1 and value=50. Finally:

INSERT INTO tbl VALUES (1,200) ON DUPLICATE KEY UPDATE value=200;

You now have a single record with id=1 and value=200.

CSS

  overflow-y: hidden
}

Javascript
``let body = document.querySelector('body');
if(condition)  {
 //disable scroll on the entire body
 body?.classList.add("disable-scroll");
} 
else {
 //to remove the class attrib
 body?.removeAttribute("class");
 //or to remove the disable-scroll class only
 body?.classList.remove("dissble-scroll");
}

This is way better than long code. easy to understand

How OAuth 2.0 works in real life:

I was driving by Olaf's bakery on my way to work when I saw the most delicious donut in the window -- I mean, the thing was dripping chocolatey goodness. So I went inside and demanded "I must have that donut!". He said "sure that will be $30."

Yeah I know, $30 for one donut! It must be delicious! I reached for my wallet when suddenly I heard the chef yell "NO! No donut for you". I asked: why? He said he only accepts bank transfers.

Seriously? Yep, he was serious. I almost walked away right there, but then the donut called out to me: "Eat me, I'm delicious...". Who am I to disobey orders from a donut? I said ok.

He handed me a note with his name on it (the chef, not the donut): "Tell them Olaf sent you". His name was already on the note, so I don't know what the point of saying that was, but ok.

I drove an hour and a half to my bank. I handed the note to the teller; I told her Olaf sent me. She gave me one of those looks, the kind that says, "I can read".

She took my note, asked for my id, asked me how much money was ok to give him. I told her $30 dollars. She did some scribbling and handed me another note. This one had a bunch of numbers on it, I guessed that's how they keep track of the notes.

At that point I'm starving. I rushed out of there, an hour and a half later I was back, standing in front of Olaf with my note extended. He took it, looked it over and said, "I'll be back".

I thought he was getting my donut, but after 30 minutes I started to get suspicious. So I asked the guy behind the counter "Where's Olaf?". He said "He went to get money". "What do you mean?". "He take note to bank".

Huh... so Olaf took the note that the bank gave me and went back to the bank to get money out of my account. Since he had the note the bank gave me, the bank knew he was the guy I was talking about, and because I spoke with the bank they knew to only give him $30.

It must have taken me a long time to figure that out because by the time I looked up, Olaf was standing in front of me finally handing me my donut. Before I left I had to ask, "Olaf, did you always sell donuts this way?". "No, I used to do it different."

Huh. As I was walking back to my car my phone rang. I didn't bother answering, it was probably my job calling to fire me, my boss is such a ***. Besides, I was caught up thinking about the process I just went through.

I mean think about it: I was able to let Olaf take $30 out of my bank account without having to give him my account information. And I didn't have to worry that he would take out too much money because I already told the bank he was only allowed to take $30. And the bank knew he was the right guy because he had the note they gave me to give to Olaf.

Ok, sure I would rather hand him $30 from my pocket. But now that he had that note I could just tell the bank to let him take $30 every week, then I could just show up at the bakery and I didn't have to go to the bank anymore. I could even order the donut by phone if I wanted to.

Of course I'd never do that -- that donut was disgusting.

I wonder if this approach has broader applications. He mentioned this was his second approach, I could call it Olaf 2.0. Anyway I better get home, I gotta start looking for a new job. But not before I get one of those strawberry shakes from that new place across town, I need something to wash away the taste of that donut.

These are the default settings I have for /etc/network/interfaces (including WiFi settings) for my Raspberry Pi 1:

auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp

Use filter, or if the number of dictionaries in exampleSet is too high, use ifilter of the itertools module. It would return an iterator, instead of filling up your system's memory with the entire list at once:

from itertools import ifilter
for elem in ifilter(lambda x: x['type'] in keyValList, exampleSet):
    print elem

The Facebook "Graph API Rate Limiting" docs says that an error with code #4 is an app level rate limit, which is different than user level rate limits. Although it doesn't give any exact numbers, it describes their app level rate-limit as:

This rate limiting is applied globally at the app level. Ads api calls are excluded.

• Rate limiting happens real time on sliding window for past one hour.
• Stats is collected for number of calls and queries made, cpu time spent, memory used for each app.
• There is a limit for each resource multiplied by monthly active users of a given app.
• When the app uses more than its allowed resources the error is thrown.
• Error, Code: 4, Message: Application request limit reached

The docs also give recommendations for avoiding the rate limits. For app level limits, they are:

Recommendations:

• Verify the error code (4) to confirm the throttling type.
• Do not make burst of calls, spread out the calls throughout the day.
• Do smart fetching of data (important data, non duplicated data, etc).
  • Real-time insights, make sure API calls are structured in a way that you can read insights for as many as Page posts as possible, with minimum number of requests.
  • Don't fetch users feed twice (in the case that two App users have a specific friend in common)
  • Don't fetch all user's friends feed in a row if the number of friends is more than 250. Separate the fetches over different days. As an option, fetch first the app user's news feed (me/home) in order to detect which friends are more important to the App user. Then, fetch those friends feeds first.
• Consider to limit/filter the requests by using the following parameters: "since", "until", "limit"
• For page related calls use realtime updates to subscribe to changes in data.
• Field expansion allows ton "join" multiple graph queries into a single call.
• Etags to check if the data querying has changed since the last check.
• For page management developers who does not have massive user base, have the admins of the page to accept the app to increase the number of users.

Finally, the docs give the following informational tips:

• Batching calls will not reduce the number of api calls.
• Making parallel calls will not reduce the number of api calls.

    @IBAction func chooseProfilePicBtnClicked(sender: AnyObject) {

you can achieve that using Following example uses addBatch & executeBatch commands to execute multiple SQL commands simultaneously.

Batch Processing allows you to group related SQL statements into a batch and submit them with one call to the database. reference

When you send several SQL statements to the database at once, you reduce the amount of communication overhead, thereby improving performance.

• JDBC drivers are not required to support this feature. You should use the DatabaseMetaData.supportsBatchUpdates() method to determine if the target database supports batch update processing. The method returns true if your JDBC driver supports this feature.
• The addBatch() method of Statement, PreparedStatement, and CallableStatement is used to add individual statements to the batch. The executeBatch() is used to start the execution of all the statements grouped together.
• The executeBatch() returns an array of integers, and each element of the array represents the update count for the respective update statement.
• Just as you can add statements to a batch for processing, you can remove them with the clearBatch() method. This method removes all the statements you added with the addBatch() method. However, you cannot selectively choose which statement to remove.

EXAMPLE:

import java.sql.*;

public class jdbcConn {
   public static void main(String[] args) throws Exception{
      Class.forName("org.apache.derby.jdbc.ClientDriver");
      Connection con = DriverManager.getConnection
      ("jdbc:derby://localhost:1527/testDb","name","pass");

      Statement stmt = con.createStatement
      (ResultSet.TYPE_SCROLL_SENSITIVE,
      ResultSet.CONCUR_UPDATABLE);
      String insertEmp1 = "insert into emp values
      (10,'jay','trainee')";
      String insertEmp2 = "insert into emp values
      (11,'jayes','trainee')";
      String insertEmp3 = "insert into emp values
      (12,'shail','trainee')";
      con.setAutoCommit(false);
      stmt.addBatch(insertEmp1);//inserting Query in stmt
      stmt.addBatch(insertEmp2);
      stmt.addBatch(insertEmp3);
      ResultSet rs = stmt.executeQuery("select * from emp");
      rs.last();
      System.out.println("rows before batch execution= "
      + rs.getRow());
      stmt.executeBatch();
      con.commit();
      System.out.println("Batch executed");
      rs = stmt.executeQuery("select * from emp");
      rs.last();
      System.out.println("rows after batch execution= "
      + rs.getRow());
   }

I've not tried to run below, though. I think this's a tricky way.

map{print $_;} @array;

PEP-8 recommends you indent lines to the opening parentheses if you put anything on the first line, so it should either be indenting to the opening bracket:

urlpatterns = patterns('',
                       url(r'^$', listing, name='investment-listing'))

or not putting any arguments on the starting line, then indenting to a uniform level:

urlpatterns = patterns(
    '',
    url(r'^$', listing, name='investment-listing'),
)

urlpatterns = patterns(
    '', url(r'^$', listing, name='investment-listing'))

I suggest taking a read through PEP-8 - you can skim through a lot of it, and it's pretty easy to understand, unlike some of the more technical PEPs.

The way a cherry-pick works is by taking the diff a changeset represents (the difference between the working tree at that point and the working tree of its parent), and applying it to your current branch.

So, if a commit has two or more parents, it also represents two or more diffs - which one should be applied?

You're trying to cherry pick fd9f578, which was a merge with two parents. So you need to tell the cherry-pick command which one against which the diff should be calculated, by using the -m option. For example, git cherry-pick -m 1 fd9f578 to use parent 1 as the base.

I can't say for sure for your particular situation, but using git merge instead of git cherry-pick is generally advisable. When you cherry-pick a merge commit, it collapses all the changes made in the parent you didn't specify to -m into that one commit. You lose all their history, and glom together all their diffs. Your call.

The easiest answer: Add margin:auto; to inner.

<div class="outer">
  <div class="inner">
    Foo foo
  </div>
</div>

CSS code

.outer{
    width: 100%;
    height: 300px;
    background: yellow;
}

.inner{
    width: 30%;
    height: 200px;
    margin: auto;
    background: red;
    text-align: center
}

Check my CodePen link: http://codepen.io/feizel/pen/QdJJrK

This works, even when there are middle names:

=MID(A2,FIND(CHAR(1),SUBSTITUTE(A2," ",CHAR(1),LEN(A2)-LEN(SUBSTITUTE(A2," ",""))))+1,LEN(A2))

If you want everything BUT the last name, check out this answer.

If there are trailing spaces in your names, then you may want to remove them by replacing all instances of A2 by TRIM(A2) in the above formula.

Note that it is only by pure chance that your first formula =RIGHT(A2,FIND(" ",A2,1)-1) kind of works for Alistair Stevens. This is because "Alistair" and " Stevens" happen to contain the same number of characters (if you count the leading space in " Stevens").

1. Open Vs Code
2. Go to view
3. Click on terminal to open a terminal in VS Code
4. Copy the link for your existing repository from your GitHub page.
5. Type “git clone” and paste the link in addition i.e “git clone https://github.com/...”
6. This will open the repository in your Vs Code Editor.

Note that you can also use the InOrder class to verify that various methods are called in order on a single mock, not just on two or more mocks.

Suppose I have two classes Foo and Bar:

public class Foo {
  public void first() {}
  public void second() {}
}

public class Bar {
  public void firstThenSecond(Foo foo) {
    foo.first();
    foo.second();
  }
}

I can then add a test class to test that Bar's firstThenSecond() method actually calls first(), then second(), and not second(), then first(). See the following test code:

public class BarTest {
  @Test
  public void testFirstThenSecond() {
    Bar bar = new Bar();
    Foo mockFoo = Mockito.mock(Foo.class);
    bar.firstThenSecond(mockFoo);

    InOrder orderVerifier = Mockito.inOrder(mockFoo);
    // These lines will PASS
    orderVerifier.verify(mockFoo).first();
    orderVerifier.verify(mockFoo).second();

    // These lines will FAIL
    // orderVerifier.verify(mockFoo).second();
    // orderVerifier.verify(mockFoo).first();
  }
}

The repository owner should give you a contributor permission:

Today things have changed a little.

Now we avoid use ProgressDialog to show spinning progress:

If you want to put in your app a spinning progress you should use an Activity indicators:

It is only required if you aren't using the default values for version and encoding (which you are in that example).

I wrote these classes which served me well. It's simple yet pragmatic.

public class HtmlAttribute
{
    public string Name { get; set; }
    public string Value { get; set; }

    public HtmlAttribute(string name) : this(name, null) { }

    public HtmlAttribute(
        string name,
        string @value)
    {
        this.Name = name;
        this.Value = @value;
    }

    public override string ToString()
    {
        if (string.IsNullOrEmpty(this.Value))
            return this.Name;

        if (this.Value.Contains('"'))
            return string.Format("{0}='{1}'", this.Name, this.Value);

        return string.Format("{0}=\"{1}\"", this.Name, this.Value);
    }
}

public class HtmlElement
{
    protected List<HtmlAttribute> Attributes { get; set; }
    protected List<object> Childs { get; set; }
    public string Name { get; set; }
    protected HtmlElement Parent { get; set; }

    public HtmlElement() : this(null) { }

    public HtmlElement(string name, params object[] childs)
    {
        this.Name = name;
        this.Attributes = new List<HtmlAttribute>();
        this.Childs = new List<object>();

        if (childs != null && childs.Length > 0)
        {
            foreach (var c in childs)
            {
                Add(c);
            }
        }
    }

    public void Add(object o)
    {
        var a = o as HtmlAttribute;
        if (a != null)
            this.Attributes.Add(a);
        else
        {
            var h = o as HtmlElement;
            if (h != null && !string.IsNullOrEmpty(this.Name))

        }
    }

    public override string ToString()
    {
        var result = new StringBuilder();

        if (!string.IsNullOrEmpty(this.Name))
        {
            result.Append(string.Format("<{0}", this.Name));
            if (this.Attributes.Count > 0)
            {
                result.Append(" ");
                foreach (var attr in this.Attributes)

Justin has given you some very fine tips :)

You will also get that error if the cell where you are performing the calculation has an error resulting from a formula.

For example if Cell A1 has #DIV/0! error then you will get "Excel VBA Run-time error '13' Type mismatch" when performing this code

Sheets("Sheet1").Range("A1").Value - 1

I have made some slight changes to your code. Could you please test it for me? Copy the code with the line numbers as I have deliberately put them there.

Option Explicit

Sub Sample()
  Dim ws As Worksheet
  Dim x As Integer, i As Integer, a As Integer, y As Integer
  Dim name As String
  Dim lastRow As Long
10        On Error GoTo Whoa

20        Application.ScreenUpdating = False

30        name = InputBox("Please insert the name of the sheet")

40        If Len(Trim(name)) = 0 Then Exit Sub

50        Set ws = Sheets(name)

60        With ws
70            If Not IsError(.Range("BE4").Value) Then
80                x = Val(.Range("BE4").Value)
90            Else
100               MsgBox "Please check the value of cell BE4. It seems to have an error"
110               GoTo LetsContinue
120           End If

130           .Range("BF4").Value = x

140           lastRow = .Range("BE" & Rows.Count).End(xlUp).Row

150           For i = 5 To lastRow
160               If IsError(.Range("BE" & i)) Then
170                   MsgBox "Please check the value of cell BE" & i & ". It seems to have an error"
180                   GoTo LetsContinue
190               End If

200               a = 0: y = Val(.Range("BE" & i))
210               If y <> x Then
220                   If y <> 0 Then
230                       If y = 3 Then
240                           a = x
250                           .Range("BF" & i) = Val(.Range("BE" & i)) - x

260                           x = Val(.Range("BE" & i)) - x
270                       End If
280                       .Range("BF" & i) = Val(.Range("BE" & i)) - a
290                       x = Val(.Range("BE" & i)) - a
300                   Else
310                       .Range("BF" & i).ClearContents
320                   End If

360           Next i

Using JSONSerialization always felt unSwifty and unwieldy, but it is even more so with the arrival of Codable in Swift 4. If you wield a [String:Any] in front of a simple struct it will ... hurt. Check out this in a Playground:

import Cocoa

let data = "[{\"form_id\":3465,\"canonical_name\":\"df_SAWERQ\",\"form_name\":\"Activity 4 with Images\",\"form_desc\":null}]".data(using: .utf8)!

struct Form: Codable {
    let id: Int
    let name: String
    let description: String?

    private enum CodingKeys: String, CodingKey {
        case id = "form_id"
        case name = "form_name"
        case description = "form_desc"
    }
}

do {
    let f = try JSONDecoder().decode([Form].self, from: data)
    print(f)
    print(f[0])
} catch {
    print(error)
}

With minimal effort handling this will feel a whole lot more comfortable. And you are given a lot more information if your JSON does not parse properly.

I had the same problem and I solved it with the following steps

1. Help > Install New Software...
2. Select "Eclipse Web Tools Platform Repository (http://download.eclipse.org/webtools/updates)" from the "Work with" drop-down.
3. Select "Web Tools Platform (WTP)" and "Project Provided Components".

Complete all the installation steps and restart Eclipse. You'll see a bunch of servers when you try to add a server runtime environment.

The datetime.now() is evaluated when the class is created, not when new record is being added to the database.

To achieve what you want define this field as:

date = models.DateTimeField(auto_now_add=True)

This way the date field will be set to current date for each new record.
