I had similar situation. I found that one of my config maps was duplicated. I had two configmaps for the same namespace. One had the correct namespace reference, the other was pointing to the wrong namespace.

I deleted and recreated the configmap with the correct file (or fixed file). I am only using one, and that seemed to make the particular cluster happier.

So I would check the files for any typos or duplicate items that could be causing conflict.

This command worked fine for me:

RUN apt-get -y install python3-pip

My case used stored procedure instead of raw SQL

Created a class

Public class School
{
    [Key]
    public Guid SchoolId { get; set; }
    public string Name { get; set; }
    public string Branch { get; set; }
    public int NumberOfStudents  { get; set; }
}

Added below on my DbContext class

public DbSet<School> SP_Schools { get; set; }

To execute the stored procedure:

var MySchools = _db.SP_Schools.FromSqlRaw("GetSchools @schoolId, @page, @size ",
              new SqlParameter("schoolId", schoolId),
              new SqlParameter("page", page),
              new SqlParameter("size", size)))
.IgnoreQueryFilters();

In this case what you can do is : Go in developer options on the device Uncheck "USB Debugging" then check it again A confirmation box should then appear DvxWifiScan

In sequence:

    adb kill-server

• in your DEVICE SETUP, go to developer-options end disable usb-debugging

• press REVOKE USB debugging authorizations, click OK

• enable usb-debugging

  adb start-server
  

I have a rooted Samsung Galaxy Trend Plus (GT-S7580).

Running 'adb root' gives me the same 'adbd cannot run as root in production builds' error.

For devices that have Developer Options -> Root access, choose "ADB only" to provide adb root access to the device (as suggested by NgaNguyenDuy).

Then try to run the command as per the solution at Launch a script as root through ADB. In my case, I just wanted to run the 'netcfg rndis0 dhcp' command, and I did it this way:

adb shell "su -c netcfg rndis0 dhcp"

Please check whether you are making any mistakes while running it this way.

If it still does not work, check whether you rooted the device correctly. If still no luck, try installing a custom ROM such as Cyanogen Mod in order for 'adb root' to work.

For those who rooted the Android device with Magisk, you can install adb_root from https://github.com/evdenis/adb_root. Then adb root can run smoothly.

BootFlat

You can also try BootFlat, which has a section in their documentation specifically for crafting Timelines:

Root cause: Corrupted user profile of user account used to start database

The main thread here seems to be a corrupted user account profile for the account that is used to start the DB engine. This is the account that was specified for the "SQL Server Database" engine during installation. In the setup event log, it's also indicated by the following entry:

SQLSVCACCOUNT:                 NT AUTHORITY\SYSTEM

According to the link provided by @royki:

The root cause of this issue, in most cases, is that the profile of the user being used for the service account (in my case it was local system) is corrupted.

This would explain why other respondents had success after changing to different accounts:

• bmjjr suggests changing to "NT AUTHORITY\NETWORK SERVICE"
• comments to @bmjjr indicate different accounts "I used NT AUTHORITY\LOCAL SERVICE. That helped too"
• @Julio Nobre had success with "NT Authority\System "

Fix: reset the corrupt user profile

To fix the user profile that's causing the error, follow the steps listed KB947215.

The main steps from KB947215 are summarized as follows:-

1. Open regedit
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

3. Navigate to the SID for the corrupted profile

   To find the SID, click on each SID GUID, review the value for the ProfileImagePath value, and see if it's the correct account. For system accounts, there's a different way to know the SID for the account that failed:

The main system account SIDs of interest are:

SID          Name               Also Known As
S-1-5-18     Local System       NT AUTHORITY\SYSTEM
S-1-5-19     LocalService       NT AUTHORITY\LOCAL SERVICE
S-1-5-20     NetworkService     NT AUTHORITY\NETWORK SERVICE

For information on additional SIDs, see Well-known security identifiers in Windows operating systems.

4. If there are two entries (e.g. with a .bak) at the end for the SID in question, or the SID in question ends in .bak, ensure to follow carefully the steps in the KB947215 article.
5. Reset the values for RefCount and State to be 0.
6. Reboot.
7. Retry the SQL Server installation.

If you are desperate you can try this:

git clone ssh://[email protected]/path/to/project destination --depth=1

It will get your data, but you'll lose the history. I went with trial and error on my repo and --depth=10 worked, but --depth=50 gave me failure.

Create CA certificate

openssl genrsa -out privateKey.pem 4096
openssl req -new -x509 -nodes -days 3600 -key privateKey.pem -out caKey.pem

I finally found out how to do this! Basically you need to run adb shell first and then while you're in the shell run su, which will switch the shell to run as root!

$: adb shell
$: su

The one problem I still have is that sqlite3 is not installed so the command is not recognized.

In the code of the button that saves the changes to the database eg the update button, add the following lines of code:

MyDataGridView.DataSource = MyTableBindingSource

MyDataGridView.Update()

MyDataGridView.RefreshEdit()

In my case this error message appeared because the package I was trying to install (storm) was not supported for Python 3.

WITH PATHLIB MODULE (UPDATED ANSWER)

One should consider using pathlib for new development. It is in the stdlib for Python3.4, but available on PyPI for earlier versions. This library provides a more object-orented method to manipulate paths <opinion> and is much easier read and program with </opinion>.

>>> import pathlib
>>> existGDBPath = pathlib.Path(r'T:\Data\DBDesign\DBDesign_93_v141b.mdb')
>>> wkspFldr = existGDBPath.parent
>>> print wkspFldr
Path('T:\Data\DBDesign')

WITH OS MODULE

Use the os.path module:

>>> import os
>>> existGDBPath = r'T:\Data\DBDesign\DBDesign_93_v141b.mdb'
>>> wkspFldr = os.path.dirname(existGDBPath)
>>> print wkspFldr 
'T:\Data\DBDesign'

You can go ahead and assume that if you need to do some sort of filename manipulation it's already been implemented in os.path. If not, you'll still probably need to use this module as the building block.

Try this code,

public void ConnectToAccess()
{
    System.Data.OleDb.OleDbConnection conn = new 
        System.Data.OleDb.OleDbConnection();
    // TODO: Modify the connection string and include any
    // additional required properties for your database.
    conn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;" +
        @"Data source= C:\Documents and Settings\username\" +
        @"My Documents\AccessFile.mdb";
    try
    {
        conn.Open();
        // Insert code to process data.
    }
        catch (Exception ex)
    {
        MessageBox.Show("Failed to connect to data source");
    }
    finally
    {
        conn.Close();
    }
}

I'm answering on specific to this error code(08s01).

usually, MySql close socket connections are some interval of time that is wait_timeout defined on MySQL server-side which by default is 8hours. so if a connection will timeout after this time and the socket will throw an exception which SQLState is "08s01".

1.use connection pool to execute Query, make sure the pool class has a function to make an inspection of the connection members before it goes time_out.

2.give a value of <wait_timeout> greater than the default, but the largest value is 24 days

3.use another parameter in your connection URL, but this method is not recommended, and maybe deprecated.

The problem you are having is the query command is taking too long. I believe that the default timeout for a query to execute is 15 seconds. You need to set the CommandTimeout (in seconds) so that it is long enough for the command to complete its execution. The "CommandTimeout" is different than the "Connection Timeout" in your connection string and must be set for each command.

In your sql Selecting Event, use the command:

e.Command.CommandTimeout = 60

for example:

Protected Sub SqlDataSource1_Selecting(sender As Object, e As System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs)
    e.Command.CommandTimeout = 60
End Sub

This is because of

String outStr = obj.toString("UTF-8");

Send the byte[] which you can get from your ByteArrayOutputStream and use it as such in your ByteArrayInputStream to construct your GZIPInputStream. Following are the changes which need to be done in your code.

byte[] compressed = compress(string); //In the main method

public static byte[] compress(String str) throws Exception {
    ...
    ...
    return obj.toByteArray();
}

public static String decompress(byte[] bytes) throws Exception {
    ...
    GZIPInputStream gis = new GZIPInputStream(new ByteArrayInputStream(bytes));
    ...
}

for me , using export PYTHONIOENCODING=UTF-8 before executing python command worked .

Since you have not replied to my comment above, I am posting a solution for both.

You are missing ' in Extended Properties

For Excel 2003 try this (TRIED AND TESTED)

    private void button1_Click(object sender, EventArgs e)
    {
        String name = "Items";
        String constr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" +
                        "C:\\Sample.xls" + 
                        ";Extended Properties='Excel 8.0;HDR=YES;';";

        OleDbConnection con = new OleDbConnection(constr);
        OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]", con);
        con.Open();

        OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
        DataTable data = new DataTable();
        sda.Fill(data);
        grid_items.DataSource = data;
    }

BTW, I stopped working with Jet longtime ago. I use ACE now.

    private void button1_Click(object sender, EventArgs e)
    {
        String name = "Items";
        String constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" +
                        "C:\\Sample.xls" + 
                        ";Extended Properties='Excel 8.0;HDR=YES;';";

        OleDbConnection con = new OleDbConnection(constr);
        OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]", con);
        con.Open();

        OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
        DataTable data = new DataTable();
        sda.Fill(data);
        grid_items.DataSource = data;
    }

For Excel 2007+

    private void button1_Click(object sender, EventArgs e)
    {
        String name = "Items";
        String constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" +
                        "C:\\Sample.xlsx" + 
                        ";Extended Properties='Excel 12.0 XML;HDR=YES;';";

        OleDbConnection con = new OleDbConnection(constr);
        OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]", con);
        con.Open();

        OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
        DataTable data = new DataTable();
        sda.Fill(data);
        grid_items.DataSource = data;
    }

When I inspected the problem, I have noticed that the following dll were missing in the output folder. The simple solution is copy Entityframework.dll and Entityframework.sqlserver.dll with the app.config to the output folder if the application is on debug mode. At the same time change, the build option parameter "Copy to output folder" of app.config to copy always. This will solve your problem.

I just had the same problem with Parent/Child collections and found that post which has solved my case. I Only wanted to show the List of parent collection items and didn't need any of the child data, therefore i used the following and it worked fine:

JsonConvert.SerializeObject(ResultGroups, Formatting.None,
                        new JsonSerializerSettings()
                        { 
                            ReferenceLoopHandling = ReferenceLoopHandling.Ignore
                        });

JSON.NET Error Self referencing loop detected for type

it also referes to the Json.NET codeplex page at:

http://json.codeplex.com/discussions/272371

Documentation: ReferenceLoopHandling setting

I tried almost all the listed solutions, none worked for me until I restarted the machine and then mysql server restarted when I issued the command "service mysql restart".

In my Visual Studio 2019 it worked only after I set the AutoSizeColumnsMode property to None.

Best approach is to undo the merge and perform the merge again. Often you get the order of things messed up. Try and fix the conflicts and get yourself into a mess.

So undo do it and merge again.

Make sure that you have the appropriate diff tools setup for your environment. I am on a mac and use DIFFMERGE. I think DIFFMERGE is available for all environments. Instructions are here: Install DIFF Merge on a MAC

I have this helpful resolving my conflicts: Git Basic-Merge-Conflicts

At the present time, there is a simple way to fix this problem:

1. Go to Tools ? MarketPlace and search for "PDI MySQL Plugin"
2. Install it ( this will automatically install the missing driver here: data-integration\plugins\databases\pdi-mysql-plugin\lib )
3. Restart Pentaho
4. Done.

Filling a DataSet with multiple tables can be done by sending multiple requests to the database, or in a faster way: Multiple SELECT statements can be sent to the database server in a single request. The problem here is that the tables generated from the queries have automatic names Table and Table1. However, the generated table names can be mapped to names that should be used in the DataSet.

SqlDataAdapter adapter = new SqlDataAdapter(
      "SELECT * FROM Customers; SELECT * FROM Orders", connection);
adapter.TableMappings.Add("Table", "Customer");
adapter.TableMappings.Add("Table1", "Order");

adapter.Fill(ds);

A common gotcha for directories hosted outside of the default /var/www/ is that the Apache user doesn't just need permissions to the directory and subdirectories where the site is being hosted. Apache requires permissions to all the directories all the way up to the root of the file system where the site is hosted. Apache automatically gets permissions assigned to /var/www/ when it's installed, so if your host directory is directly underneath that then this doesn't apply to you. Edit: Daybreaker has reported that his Apache was installed without correct access permissions to the default directory.

For example, you've got a development machine and your site's directory is:

/username/home/Dropbox/myamazingsite/

You may think you can get away with:

chgrp -R www-data /username/home/Dropbox/myamazingsite/
chmod -R 2750 /username/home/Dropbox/myamazingsite/

because this gives Apache permissions to access your site's directory? Well that's correct but it's not sufficient. Apache requires permissions all the way up the directory tree so what you need to do is:

chgrp -R www-data /username/
chmod -R 2750 /username/

Obviously I would not recommend giving access to Apache on a production server to a complete directory structure without analysing what's in that directory structure. For production it's best to keep to the default directory or another directory structure that's just for holding web assets.

Edit2: as u/chimeraha pointed out, if you're not sure what you're doing with the permissions, it'd be best to move your site's directory out of your home directory to avoid potentially locking yourself out of your home directory.

Not sure why the file path is not working, I have some similar code that works fine. But if with two "\" it works, you can always do path = path.Replace(@"\", @"\\");

You will have to annotate your service with @Service since you have said I am using annotations for mapping

Integer.parseInt(hex,16);    
System.out.print(Integer.toBinaryString(hex));

Parse hex(String) to integer with base 16 then convert it to Binary String using toBinaryString(int) method

example

int num = (Integer.parseInt("A2B", 16));
System.out.print(Integer.toBinaryString(num));

Will Print

101000101011

Max Hex vakue Handled by int is FFFFFFF

i.e. if FFFFFFF0 is passed ti will give error

The problem in my case was that the database name was incorrect.
I solved the problem by referring the correct database name in the field as below

<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/myDatabase</property>

I do it like this:

internal class Repository : IRepository {

    private readonly Func<IDbConnection> _connectionFactory;

    public Repository(Func<IDbConnection> connectionFactory) 
    {
        _connectionFactory = connectionFactory;
    }

    public IWidget Get(string key) {
        using(var conn = _connectionFactory()) 
        {
            return conn.Query<Widget>(
               "select * from widgets with(nolock) where widgetkey=@WidgetKey", new { WidgetKey=key });
        }
    }
}

Then, wherever I wire-up my dependencies (ex: Global.asax.cs or Startup.cs), I do something like:

var connectionFactory = new Func<IDbConnection>(() => {
    var conn = new SqlConnection(
        ConfigurationManager.ConnectionStrings["connectionString-name"];
    conn.Open();
    return conn;
});

yourTextView.setTextColor(color);

Or, in your case: yourTextView.setTextColor(0xffbdbdbd);

You should provide the second database information in `application/config/database.php´

Normally, you would set the default database group, like so:

$db['default']['hostname'] = "localhost";
$db['default']['username'] = "root";
$db['default']['password'] = "";
$db['default']['database'] = "database_name";
$db['default']['dbdriver'] = "mysql";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = FALSE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";
$db['default']['swap_pre'] = "";
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;

Notice that the login information and settings are provided in the array named $db['default'].

You can then add another database in a new array - let's call it 'otherdb'.

$db['otherdb']['hostname'] = "localhost";
$db['otherdb']['username'] = "root";
$db['otherdb']['password'] = "";
$db['otherdb']['database'] = "other_database_name";
$db['otherdb']['dbdriver'] = "mysql";
$db['otherdb']['dbprefix'] = "";
$db['otherdb']['pconnect'] = TRUE;
$db['otherdb']['db_debug'] = FALSE;
$db['otherdb']['cache_on'] = FALSE;
$db['otherdb']['cachedir'] = "";
$db['otherdb']['char_set'] = "utf8";
$db['otherdb']['dbcollat'] = "utf8_general_ci";
$db['otherdb']['swap_pre'] = "";
$db['otherdb']['autoinit'] = TRUE;
$db['otherdb']['stricton'] = FALSE;

Now, to actually use the second database, you have to send the connection to another variabel that you can use in your model:

function my_model_method()
{
  $otherdb = $this->load->database('otherdb', TRUE); // the TRUE paramater tells CI that you'd like to return the database object.

  $query = $otherdb->select('first_name, last_name')->get('person');
  var_dump($query);
}

That should do it. The documentation for connecting to multiple databases can be found here: http://codeigniter.com/user_guide/database/connecting.html

If the file is large, you may not want to load it entirely into memory at once. This approach avoids that. (Of course, making a dict out of it could still take up some RAM, but it's guaranteed to be smaller than the original file.)

my_dict = {}
for i, line in enumerate(file):
    if (i - 8) % 7:
        continue
    k, v = line.split("\t")[:3:2]
    my_dict[k] = v

Edit: Not sure where I got extend from before. I meant update

I was ultimately able to resolve the solution by setting the column type in the flat file connection to be of type "database date [DT_DBDATE]"

Apparently the differences between these date formats are as follow:

DT_DATE A date structure that consists of year, month, day, and hour.

DT_DBDATE A date structure that consists of year, month, and day.

DT_DBTIMESTAMP A timestamp structure that consists of year, month, hour, minute, second, and fraction

By changing the column type to DT_DBDATE the issue was resolved - I attached a Data Viewer and the CYCLE_DATE value was now simply "12/20/2010" without a time component, which apparently resolved the issue.

I think, there is something wrong with PHP configration.
First, debug your database connection using this script at the end of ./config/database.php :

...
  ...
  ...
  echo '<pre>';
  print_r($db['default']);
  echo '</pre>';

  echo 'Connecting to database: ' .$db['default']['database'];
  $dbh=mysql_connect
  (
    $db['default']['hostname'],
    $db['default']['username'],
    $db['default']['password'])
    or die('Cannot connect to the database because: ' . mysql_error());
    mysql_select_db ($db['default']['database']);

    echo '<br />   Connected OK:'  ;
    die( 'file: ' .__FILE__ . ' Line: ' .__LINE__); 

Then see what the problem is.

DataSet ds = new DataSet();

using (OleDbConnection connection = new OleDbConnection(connectionString))
using (OleDbCommand command = new OleDbCommand(query, connection))
using (OleDbDataAdapter adapter = new OleDbDataAdapter(command))
{
    adapter.Fill(ds);
}

return ds;

use the syntax .ToList() to convert object read from db to list to avoid being re-read again.Hope this would work for it. Thanks.

You can compare two date by this method also

        switch ([currenttimestr  compare:endtimestr])
        {
            case NSOrderedAscending:

                // dateOne is earlier in time than dateTwo
                break;

            case NSOrderedSame:

                // The dates are the same
                break;
            case NSOrderedDescending:

                // dateOne is later in time than dateTwo


                break;

        }

maybe there are some unmerged paths in your git repository that you have to resolve before stashing.

This problem appears when we are using any third party solution, without using the handlers for the cleanup activitiy. For me this was happening for EhCache. We were using EhCache in our project for caching. And often we used to see following error in the logs

 SEVERE: The web application [/products] appears to have started a thread named [products_default_cache_configuration] but has failed to stop it. This is very likely to create a memory leak.

SEVERE: The web application [/products] appears to have started a thread named [Statistics Thread-products_default_cache_configuration-1] but has failed to stop it. This is very likely to create a memory leak.

And we often noticed tomcat failing for OutOfMemory error during development where we used to do backend changes and deploy the application multiple times for reflecting our changes.

This is the fix we did

<listener>
  <listener-class>
     net.sf.ehcache.constructs.web.ShutdownListener
  </listener-class>
</listener>

So point I am trying to make is check the documentation of the third party libraries which you are using. They should be providing some mechanisms to clean up the threads during shutdown. Which you need to use in your application. No need to re-invent the wheel unless its not provided by them. The worst case is to provide your own implementation.

Reference for EHCache Shutdown http://www.ehcache.org/documentation/2.8/operations/shutdown.html

They serve the actual image inside CSS so there will be less HTTP requests per page.

Please check if you open up a new connection with each of your requests (mysql_connect(...)). If you do so, make sure you close the connection afterwards (using mysql_close($link)).

Also, you should consider changing this behaviour as keeping one steady connection for each user may be a better way to accomplish your task.

If you didn't already, take a look at this obvious, but nonetheless useful information resource: http://php.net/manual/function.mysql-connect.php

This specifies the default collation for the database. Every text field that you create in tables in the database will use that collation, unless you specify a different one.

A database always has a default collation. If you don't specify any, the default collation of the SQL Server instance is used.

The name of the collation that you use shows that it uses the Latin1 code page 1, is case insensitive (CI) and accent sensitive (AS). This collation is used in the USA, so it will contain sorting rules that are used in the USA.

The collation decides how text values are compared for equality and likeness, and how they are compared when sorting. The code page is used when storing non-unicode data, e.g. varchar fields.

I had the same problem today. My persistence.xml was in the wrong location. I had to put it in the following path:

project/src/main/resources/META-INF/persistence.xml

I think, bwawok's answer is wrong at some point:

if you do

git reset --soft c14809fa

It will make your local files changed to be like they were then, but leave your history etc. the same.

According to manual: git-reset, "git reset --soft"...

does not touch the index file nor the working tree at all (but resets the head to <commit>, just like all modes do). This leaves all your changed files "Changes to be committed", as git status would put it.

So it will "remove" newer commits from the branch. This means, after looking at your old code, you cannot go to the newest commit in this branch again, easily. So it does the opposide as described by bwawok: Local files are not changed (they look exactly as before "git reset --soft"), but the history is modified (branch is truncated after the specified commit).

The command for bwawok's answer might be:

git checkout <commit>

You can use this to peek at old revision: How did my code look yesterday?

What problem are you having, specifically?

@JsonIgnoreProperties is the answer.

Use something like this ::

@OneToMany(mappedBy = "course",fetch=FetchType.EAGER)
@JsonIgnoreProperties("course")
private Set<Student> students;

You could try this.

In windows go to Administrative Tools->Services And see scroll down to where it says Oracle[instanceNameHere] and see if the listener and the service itself are running. You might have to start it. You can also set it to start automatically when you right-click on it and go to properties.

Use git rebase. Specifically:

1. Use git stash to store the changes you want to add.
2. Use git rebase -i HEAD~10 (or however many commits back you want to see).
3. Mark the commit in question (a0865...) for edit by changing the word pick at the start of the line into edit. Don't delete the other lines as that would delete the commits.[^vimnote]
4. Save the rebase file, and git will drop back to the shell and wait for you to fix that commit.
5. Pop the stash by using git stash pop
6. Add your file with git add <file>.
7. Amend the commit with git commit --amend --no-edit.
8. Do a git rebase --continue which will rewrite the rest of your commits against the new one.
9. Repeat from step 2 onwards if you have marked more than one commit for edit.

[^vimnote]: If you are using vim then you will have to hit the Insert key to edit, then Esc and type in :wq to save the file, quit the editor, and apply the changes. Alternatively, you can configure a user-friendly git commit editor with git config --global core.editor "nano".

The answer is correct, however the perl documentation on how to handle deadlocks is a bit sparse and perhaps confusing with PrintError, RaiseError and HandleError options. It seems that rather than going with HandleError, use on Print and Raise and then use something like Try:Tiny to wrap your code and check for errors. The below code gives an example where the db code is inside a while loop that will re-execute an errored sql statement every 3 seconds. The catch block gets $_ which is the specific err message. I pass this to a handler function "dbi_err_handler" which checks $_ against a host of errors and returns 1 if the code should continue (thereby breaking the loop) or 0 if its a deadlock and should be retried...

$sth = $dbh->prepare($strsql);
my $db_res=0;
while($db_res==0)
{
   $db_res=1;
   try{$sth->execute($param1,$param2);}
   catch
   {
       print "caught $_ in insertion to hd_item_upc for upc $upc\n";
       $db_res=dbi_err_handler($_); 
       if($db_res==0){sleep 3;}
   }
}

dbi_err_handler should have at least the following:

sub dbi_err_handler
{
    my($message) = @_;
    if($message=~ m/DBD::mysql::st execute failed: Deadlock found when trying to get lock; try restarting transaction/)
    {
       $caught=1;
       $retval=0; # we'll check this value and sleep/re-execute if necessary
    }
    return $retval;
}

You should include other errors you wish to handle and set $retval depending on whether you'd like to re-execute or continue..

Hope this helps someone -

I had the same error. The cause was that I had created a table with wrong schema(it ought to be [dbo]). I did the following steps:

1. I dropped all tables which does not have a prefix "dbo."

2. I created and run this query:

CREATE TABLE dbo.Cars(IDCar int PRIMARY KEY NOT NULL,Name varchar(25) NOT NULL,    
CarDescription text NULL)

I was getting errors with third party and Oledb reading of a XLSX workbook. The issue appears to be a hidden worksheet that causes a error. Unhiding the worksheet enabled the workbook to import.

Disclaimer: This answer works, but is intended for educational purposes only. :) James Jones' solution is probably the best here and certainly the one I'd go with.

C# 4.0's dynamic keyword makes this even easier, if less safe:

public static dynamic GetNullableValue(this IDataRecord record, string columnName)
{
  var val = reader[columnName];

  return (val == DBNull.Value ? null : val);
}

Now you don't need the explicit type hinting on the RHS:

int? value = myDataReader.GetNullableValue("MyColumnName");

In fact, you don't need it anywhere!

var value = myDataReader.GetNullableValue("MyColumnName");

value will now be an int, or a string, or whatever type was returned from the DB.

The only problem is that this does not prevent you from using non-nullable types on the LHS, in which case you'll get a rather nasty runtime exception like:

Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: Cannot convert null to 'int' because it is a non-nullable value type

As with all code that uses dynamic: caveat coder.

Either the parameter supplied for ZIP_CODE is larger (in length) than ZIP_CODEs column width or the parameter supplied for CITY is larger (in length) than CITYs column width.

It would be interesting to know the values supplied for the two ? placeholders.

http://jtds.sourceforge.net/faq.html#driverImplementation

What is the URL format used by jTDS?

The URL format for jTDS is:

jdbc:jtds:<server_type>://<server>[:<port>][/<database>][;<property>=<value>[;...]]

... domain Specifies the Windows domain to authenticate in. If present and the user name and password are provided, jTDS uses Windows (NTLM) authentication instead of the usual SQL Server authentication (i.e. the user and password provided are the domain user and password). This allows non-Windows clients to log in to servers which are only configured to accept Windows authentication.

If the domain parameter is present but no user name and password are provided, jTDS uses its native Single-Sign-On library and logs in with the logged Windows user's credentials (for this to work one would obviously need to be on Windows, logged into a domain, and also have the SSO library installed -- consult README.SSO in the distribution on how to do this).

The first method checks if a string is null or a blank string. In your example you can risk a null reference since you are not checking for null before trimming

1- string.IsNullOrEmpty(text.Trim())

The second method checks if a string is null or an arbitrary number of spaces in the string (including a blank string)

2- string .IsNullOrWhiteSpace(text)

The method IsNullOrWhiteSpace covers IsNullOrEmpty, but it also returns true if the string contains white space.

In your concrete example you should use 2) as you run the risk of a null reference exception in approach 1) since you're calling trim on a string that may be null

for /f "usebackq tokens=*" %%a in (`echo %StringWithLeadingSpaces%`) do set StringWithout=%%a

This is very simple. for without any parameters considers spaces to be delimiters; setting "*" as the tokens parameter causes the program to gather up all the parts of the string that are not spaces and place them into a new string into which it inserts gaps of its own.

After slogging around Visual Studio I finally figured out the answer that took far longer than it should have.

In order to take an existing project without source control and put it to an existing EMPTY (this is important) GitHub repository, the process is simple, but tricky, because your first inclination is to use the Team Explorer, which is wrong and is why you're having problems.

First, add it to source control. There are some explanations of that above, and everybody gets this far.

Now, this opens an empty LOCAL repository and the trick which nobody ever tells you about is to ignore the Team Explorer completely and go to the Solution Explorer, right click the solution and click Commit.

This then commits all differences between your existing solution and the local repository, essentially updating it with all these new files. Give it a default commit name 'initial files' or whatever floats your boat and commit.

Then simply click Sync on the next screen and drop in the EMPTY GitHub repository URL. Make sure it's empty or you'll have master branch conflicts and it won't let you. So either use a new repository or delete the old one that you had previously screwed up. Bear in mind this is Visual Studio 2013, so your mileage may vary.

The basic purpose of ValidateAntiForgeryToken attribute is to prevent cross-site request forgery attacks.

A cross-site request forgery is an attack in which a harmful script element, malicious command, or code is sent from the browser of a trusted user. For more information on this please visit http://www.asp.net/mvc/overview/security/xsrfcsrf-prevention-in-aspnet-mvc-and-web-pages.

It is simple to use, you need to decorate method with ValidateAntiForgeryToken attribute as below:

[HttpPost]  
[ValidateAntiForgeryToken]  
public ActionResult CreateProduct(Product product)  
{
  if (ModelState.IsValid)  
  {
    //your logic 
  }
  return View(ModelName);
}

It is derived from System.Web.Mvc namespace.

And in your view, add this code to add the token so it is used to validate the form upon submission.

@Html.AntiForgeryToken()

It was on Chrome for Android in my case. All the static files served from a CDN with a CNAME that's SSL encrypted were not showing up. On Chrome desktop, it all showed fine.

When I properly added the certs in ca_bundle the files displayed correctly.

Chrome for Android takes encryption seriously unlike Desktop. I hope this saves you time and stress

We can do something like this

DateTime date_temp_to = DateTime.Parse(to.Value); //to.value" is input by user (dd/MM/yyyy)

string date_from = date_temp_from.ToString("yyyy/MM/dd HH:mm");
string date_to = date_temp_to.ToString("yyyy/MM/dd HH:mm");

The following worked solidly for me

                        if (appUrl != "/")

List<T> has a Reverse() method, however it only reverses the order of two (or more) consecutive items.

your_list.Reverse(index, 2);

Where the second parameter 2 indicates we are reversing the order of 2 items, starting with the item at the given index.

In this case, myvar should be a boolean value. If this variable is true, it will show the div, if it's false.. It will hide.

Check this out.

The syntax looks right to me ... try to change it to use INNER JOIN ...

Have a look at this.

When a parameter has [FromBody], Web API uses the Content-Type header to select a formatter. In this example, the content type is "application/json" and the request body is a raw JSON string (not a JSON object).

At most one parameter is allowed to read from the message body. So this will not work:

// Caution: Will not work!    
public HttpResponseMessage Post([FromBody] int id, [FromBody] string name) { ... }

The reason for this rule is that the request body might be stored in a non-buffered stream that can only be read once.

Well, I am a bit curious, so I just tested the three myself right after asking the question ;-)

As a result:

• PyChecker is troublesome because it compiles the module to analyze it. If you don't want your code to run (e.g, it performs a SQL query), that's bad.
• PyFlakes is supposed to be light. Indeed, it decided that the code was perfect. I am looking for something quite severe so I don't think I'll go for it.
• PyLint has been very talkative and rated the code 3/10 (OMG, I'm a dirty coder !).

Strong points of PyLint:

• Very descriptive and accurate report.
• Detect some code smells. Here it told me to drop my class to write something with functions because the OO approach was useless in this specific case. Something I knew, but never expected a computer to tell me :-p
• The fully corrected code run faster (no class, no reference binding...).
• Made by a French team. OK, it's not a plus for everybody, but I like it ;-)

Cons of Pylint:

• Some rules are really strict. I know that you can change it and that the default is to match PEP8, but is it such a crime to write 'for x in seq'? Apparently yes because you can't write a variable name with less than 3 letters. I will change that.
• Very very talkative. Be ready to use your eyes.

Thanks to Rudiger Wolf, I discovered pep8 that does exactly what its name suggests: matching PEP8. It has found several syntax no-nos that Pylint did not. But Pylint found stuff that was not specifically linked to PEP8 but interesting. Both tools are interesting and complementary.

Eventually I will use both since there are really easy to install (via packages or setuptools) and the output text is so easy to chain.

To give you a little idea of their output:

pep8:

./python_mandelbrot.py:23:1: W291 trailing whitespace
./python_mandelbrot.py:41:5: E301 expected 1 blank line, found 3

Pylint:

I put all together and got easy way to convert ANSI text files to "UTF-8 No Mark":

function filesToUTF8($searchdir,$convdir,$filetypes) {
  $get_files = glob($searchdir.'*{'.$filetypes.'}', GLOB_BRACE);
  foreach($get_files as $file) {
    $expl_path = explode('/',$file);
    $filename = end($expl_path);
    $get_file_content = file_get_contents($file);
    $new_file_content = iconv(mb_detect_encoding($get_file_content, mb_detect_order(), true), "UTF-8", $get_file_content);
    $put_new_file = file_put_contents($convdir.$filename,$new_file_content);
  }
}

Usage: filesToUTF8('C:/Temp/','C:/Temp/conv_files/','php,txt');

Use this:

$('a[href^="#"]').on('click', function(event) {

    var target = $( $(this).attr('href') );

    if( target.length ) {
        event.preventDefault();
        $('html, body').animate({
            scrollTop: target.offset().top
        }, 500);
    }

});

Google says to check out getenv():

Returns an unmodifiable string map view of the current system environment.

I'm not sure how system variables differ from environment variables, however, so if you could clarify I could help out more.

As an option, you can create abstract test class covering logic inside abstract class and extend it for each subclass test. So that in this way you can ensure this logic will be tested for each child separately.

Put webpack -v into your package.json:

{
  "name": "js",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "build": "webpack -v",
    "dev": "webpack --watch"
  }
}

Then enter in the console:

npm run build

Expected output should look like:

> npm run build

> [email protected] build /home/user/repositories/myproject/js
> webpack -v

4.42.0

No, how you are doing it is correct.

http://www.w3.org/MarkUp/html-spec/html-spec_8.html#SEC8.2.2

The answers are partially correct because @@ is actually a class variable which is per class hierarchy meaning it is shared by a class, its instances and its descendant classes and their instances.

class Person
  @@people = []

  def initialize
    @@people << self
  end

  def self.people
    @@people
  end
end

class Student < Person
end

class Graduate < Student
end

Person.new
Student.new

puts Graduate.people

This will output

#<Person:0x007fa70fa24870>
#<Student:0x007fa70fa24848>

So there is only one same @@variable for Person, Student and Graduate classes and all class and instance methods of these classes refer to the same variable.

There is another way of defining a class variable which is defined on a class object (Remember that each class is actually an instance of something which is actually the Class class but it is another story). You use @ notation instead of @@ but you can't access these variables from instance methods. You need to have class method wrappers.

class Person

  def initialize
    self.class.add_person self
  end

  def self.people
    @people
  end

  def self.add_person instance
    @people ||= []
    @people << instance
  end
end

class Student < Person
end

class Graduate < Student
end

Person.new
Person.new
Student.new
Student.new
Graduate.new
Graduate.new

puts Student.people.join(",")
puts Person.people.join(",")
puts Graduate.people.join(",")

Here, @people is single per class instead of class hierarchy because it is actually a variable stored on each class instance. This is the output:

#<Student:0x007f8e9d2267e8>,#<Student:0x007f8e9d21ff38>
#<Person:0x007f8e9d226158>,#<Person:0x007f8e9d226608>
#<Graduate:0x007f8e9d21fec0>,#<Graduate:0x007f8e9d21fdf8> 

One important difference is that, you cannot access these class variables (or class instance variables you can say) directly from instance methods because @people in an instance method would refer to an instance variable of that specific instance of the Person or Student or Graduate classes.

So while other answers correctly state that @myvariable (with single @ notation) is always an instance variable, it doesn't necessarily mean that it is not a single shared variable for all instances of that class.

I was looking for caching for my phonegap app storage and I found the answer of @TecHunter which is great but done using localCache.

I found and come to know that localStorage is another alternative to cache the data returned by ajax call. So, I created one demo using localStorage which will help others who may want to use localStorage instead of localCache for caching.

Ajax Call:

$.ajax({
    type: "POST",
    dataType: 'json',
    contentType: "application/json; charset=utf-8",
    url: url,
    data: '{"Id":"' + Id + '"}',
    cache: true, //It must "true" if you want to cache else "false"
    //async: false,
    success: function (data) {
        var resData = JSON.parse(data);
        var Info = resData.Info;
        if (Info) {
            customerName = Info.FirstName;
        }
    },
    error: function (xhr, textStatus, error) {
        alert("Error Happened!");
    }
});

To store data into localStorage:

$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
if (options.cache) {
    var success = originalOptions.success || $.noop,
        url = originalOptions.url;

    options.cache = false; //remove jQuery cache as we have our own localStorage
    options.beforeSend = function () {
        if (localStorage.getItem(url)) {
            success(localStorage.getItem(url));
            return false;
        }
        return true;
    };
    options.success = function (data, textStatus) {
        var responseData = JSON.stringify(data.responseJSON);
        localStorage.setItem(url, responseData);
        if ($.isFunction(success)) success(responseJSON); //call back to original ajax call
    };
}
});

If you want to remove localStorage, use following statement wherever you want:

localStorage.removeItem("Info");

Hope it helps others!

Here's a simple solution to the nested "Complex" case statment: --Nested Case Complex Expression

select  datediff(dd,Invdate,'2009/01/31')+1 as DaysOld, 
    case when datediff(dd,Invdate,'2009/01/31')+1 >150 then 6 else
        case when datediff(dd,Invdate,'2009/01/31')+1 >120 then 5 else 
            case when datediff(dd,Invdate,'2009/01/31')+1 >90 then 4 else 
                case when datediff(dd,Invdate,'2009/01/31')+1 >60 then 3 else 
                    case when datediff(dd,Invdate,'2009/01/31')+1 >30 then 2 else 
                        case when datediff(dd,Invdate,'2009/01/31')+1 >30 then 1 end 
                    end
                end
            end
        end
    end as Bucket
from rm20090131atb

Just make sure you have an end statement for every case statement

In almost every case (that is: all cases except the very first ones), instance won't be null. Acquiring a lock is more costly than a simple check, so checking once the value of instance before locking is a nice and free optimization.

This pattern is called double-checked locking: http://en.wikipedia.org/wiki/Double-checked_locking

For anyone building an ionic app and trying to upload it. Make sure you added at least one platform to the app. Otherwise you will get this error.

If you don't declare a function and it only appears after being called, it is automatically assumed to be int, so in your case, you didn't declare

void my_print (char *);
void my_print2 (char *);

before you call it in main, so the compiler assume there are functions which their prototypes are int my_print2 (char *); and int my_print2 (char *); and you can't have two functions with the same prototype except of the return type, so you get the error of conflicting types.

As Brian suggested, declare those two methods before main.

Try this:

this.TextBox3.Text = String.Format("{0: MM.dd.yyyy}",DateTime.Now);

The following simple steps help me:

First, initialize the repository to work with Git, so that any file changes are tracked:

git init

Then, check that the remote repository that you want to associate with the alias origin exists, if not create it in git first.

$ git ls-remote https://github.com/repo-owner/repo-name.git/

If it exists, associate it with the remote "origin":

git remote add origin https://github.com:/repo-owner/repo-name.git

and check to which URL, the remote "origin" belongs to by using git remote -v:

$ git remote -v
origin  https://github.com:/repo-owner/repo-name.git (fetch)
origin  https://github.com:/repo-owner/repo-name.git (push)

Next, verify if your origin is properly aliased as follows:

$ cat ./.git/config
:
[remote "origin"]
        url = https://github.com:/repo-owner/repo-name.git
        fetch = +refs/heads/*:refs/remotes/origin/*
:

You need to see this section [remote "origin"]. You can consider to use GitHub Desktop available for both Windows and MacOS, which help me to automatically populate the missing section/s in ~./git/config file OR you can manually add it, not great, but hey it works!

[Optional]
You might also want to change the origin alias to make it more intuitive, especially if you are working with multiple origin:

git remote rename origin mynewalias

or even remove it:

git remote rm origin

Finally, on your first push, if you want master in that repository to be your default upstream. you may want to add the -u parameter

git add .
git commit -m 'First commit'
git push -u origin master

You can use the return statement inside a stored procedure to return an integer status code (and only of integer type). By convention a return value of zero is used for success.

If no return is explicitly set, then the stored procedure returns zero.

   CREATE PROCEDURE GetImmediateManager
      @employeeID INT,
      @managerID INT OUTPUT
   AS
   BEGIN
     SELECT @managerID = ManagerID 
     FROM HumanResources.Employee 
     WHERE EmployeeID = @employeeID

     if @@rowcount = 0 -- manager not found?
       return 1;
   END

And you call it this way:

DECLARE @return_status int;
DECLARE @managerID int;

EXEC @return_status = GetImmediateManager 2, @managerID output;
if @return_status = 1
  print N'Immediate manager not found!';
else 
  print N'ManagerID is ' + @managerID;
go

You should use the return value for status codes only. To return data, you should use output parameters.

If you want to return a dataset, then use an output parameter of type cursor.

Mac OS: You have to install ChromeDriver first:

brew cask install chromedriver

It will be copied to /usr/local/bin/chromedriver. Then you can use it in java code classes.

I solved this warning changing "Configuration Manager" to Release (Mixed Plataform).

In order to show the DataFrame in Jupyter Notebook just type:

   display(Name_of_the_DataFrame)

for example:

  display(df)

I had many issues involving C# and SqlServer. I ended up doing the following:

1. On SQL Server I use the DateTime column type
2. On c# I use the .ToString("yyyy-MM-dd HH:mm:ss") method

Also make sure that all your machines run on the same timezone.

Regarding the different result sets you get, your first example is "July First" while the second is "4th of July" ...

Also, the second example can be also interpreted as "April 7th", it depends on your server localization configuration (my solution doesn't suffer from this issue).

EDIT: hh was replaced with HH, as it doesn't seem to capture the correct hour on systems with AM/PM as opposed to systems with 24h clock. See the comments below.

For simple situations this works pretty well without using any other library then std::string (which is already in use).

Replace all occurences of character a with character b in some_string:

for (size_t i = 0; i < some_string.size(); ++i) {
    if (some_string[i] == 'a') {
        some_string.replace(i, 1, "b");
    }
}

If the string is large or multiple calls to replace is an issue, you can apply the technique mentioned in this answer: https://stackoverflow.com/a/29752943/3622300

function escapeJavaScriptText($string)
{
    return str_replace("\n", '\n', str_replace('"', '\"', addcslashes(str_replace("\r", '', (string)$string), "\0..\37'\\")));
}

From Python 2.5 onwards, you can use

from ..Modules import LDAPManager

The leading period takes you "up" a level in your heirarchy.

See the Python docs on intra-package references for imports.

Assuming that I is your input image and F is its Fourier Transform (i.e. F = fft2(I))

You can use this code:

F = fftshift(F); % Center FFT

F = abs(F); % Get the magnitude
F = log(F+1); % Use log, for perceptual scaling, and +1 since log(0) is undefined
F = mat2gray(F); % Use mat2gray to scale the image between 0 and 1

imshow(F,[]); % Display the result

The correct way to insert something (in Oracle) based on another record already existing is by using the MERGE statement.

Please note that this question has already been answered here on SO:

• oracle insert if row not exists
• insert if not exists oracle

This is from a php script which solves the problem perfectly with every browser I've tested (FF since 3.5, IE8+, Chrome)

header("Content-Disposition: attachment; filename=\"".$fname_local."\"");
header("Content-Type: application/force-download");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($fname));

So as far as I can see, you're doing everything correctly. Have you checked your browser settings?

Those commands won't work in the default sed that comes with Mac OS X.

From man 1 sed:

-i extension
             Edit files in-place, saving backups with the specified
             extension.  If a zero-length extension is given, no backup 
             will be saved.  It is not recommended to give a zero-length
             extension when in-place editing files, as you risk corruption
             or partial content in situations where disk space is exhausted, etc.

Tried

sed -i '.bak' 's/old/new/g' logfile*

and

for i in logfile*; do sed -i '.bak' 's/old/new/g' $i; done

Both work fine.

i know this is late , but you should try redirecting to a path and not to a file ha ha

After PushAsync use PopAsync (with this) to remove current page.

await Navigation.PushAsync(new YourSecondPage());
this.Navigation.PopAsync(this);

Have a look at this code:

HTML:

<div class="multiple-elements" data-bgcol="red"></div>
<div class="multiple-elements" data-bgcol="blue"></div>

JS:

$('.multiple-elements').each(
    function(index, element) {
        $(this).css('background-color', $(this).data('bgcol')); // Get value of HTML attribute data-bgcol="" and set it as CSS color
    }
);

this refers to the current element that the DOM engine is sort of working on, or referring to.

Another example:

<a href="#" onclick="$(this).css('display', 'none')">Hide me!</a>

Hope you understand now. The this keyword occurs while dealing with object oriented systems, or as we have in this case, element oriented systems :)

pristine tells us if a field is still virgin, and dirty tells us if the user has already typed anything in the related field:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>_x000D_
<form ng-app="" name="myForm">_x000D_
  <input name="email" ng-model="data.email">_x000D_
  <div class="info" ng-show="myForm.email.$pristine">_x000D_
    Email is virgine._x000D_
  </div>_x000D_
  <div class="error" ng-show="myForm.email.$dirty">_x000D_
    E-mail is dirty_x000D_
  </div>_x000D_
</form>

A field that has registred a single keydown event is no more virgin (no more pristine) and is therefore dirty for ever.

I had the same problem, so I dug through the poi-3.17.jar file and there was no xssf package inside.

I then went through the other files and found xssf int the poi-ooxml-3.17.jar

So it seems the solutions is to add

poi-ooxml-3.17.jar

to your project, as that seems to make it work (for me at least)

Let me try to make it simple, suppose URL of the site is www.example.com and you need to sign up by filling username and password, so we go to the login page say http://www.example.com/login.php now and view it's source code and search for the action URL it will be in form tag something like

 <form name="loginform" method="post" action="userinfo.php">

now take userinfo.php to make absolute URL which will be 'http://example.com/userinfo.php', now run a simple python script

import requests
url = 'http://example.com/userinfo.php'
values = {'username': 'user',
          'password': 'pass'}

r = requests.post(url, data=values)
print r.content

I Hope that this helps someone somewhere someday.

If you stored the complete model, not only the weights, in the HDF5 file, then it is as simple as

from keras.models import load_model
model = load_model('model.h5')

Lets say above one is your original dataframe and you want to add a new column 'old'

If age greater than 50 then we consider as older=yes otherwise False

step 1: Get the indexes of rows whose age greater than 50

row_indexes=df[df['age']>=50].index

step 2: Using .loc we can assign a new value to column

df.loc[row_indexes,'elderly']="yes"

same for age below less than 50

row_indexes=df[df['age']<50].index

df[row_indexes,'elderly']="no"

You can use the nice_hash gem: https://github.com/MarioRuiz/nice_hash

require 'nice_hash'
my_string = '{"val":"test","val1":"test1","val2":"test2"}'

# on my_hash will have the json as a hash, even when nested with arrays
my_hash = my_string.json

# you can filter and get what you want even when nested with arrays
vals = my_string.json(:val1, :val2)

# even you can access the keys like this:
puts my_hash._val1
puts my_hash.val1
puts my_hash[:val1]

As mentioned, but with a code sample:

foreach(var item in collection.ToArray())
    collection.Add(new Item...);

Here's my method of fixing this issue.

1. From the exception message, get the name of the "problem" library and the "expected" version number.

2. Find all copies of that .dll in your solution, right-click on them, and check which version of the .dll it is.

Okay, so in this example, my .dll is definitely 2.0.5022.0 (so the Exception version number is wrong).

3. Search for the version number which was shown in the Exception message in all of the .csproj files in your solution. Replace this version number with the actual number from the dll.

So, in this example, I would replace this...

<Reference Include="DocumentFormat.OpenXml, Version=2.5.5631.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL" />

... with this...

<Reference Include="DocumentFormat.OpenXml, Version=2.0.5022.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL" />

Job done !

I added the variables in the ~/.bash_profile in the following way. After you are done restart/log out and log in

export M2_HOME=/Users/robin/softwares/apache-maven-3.2.3
export ANT_HOME=/Users/robin/softwares/apache-ant-1.9.4
launchctl setenv M2_HOME $M2_HOME
launchctl setenv ANT_HOME $ANT_HOME
export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Users/robin/softwares/apache-maven-3.2.3/bin:/Users/robin/softwares/apache-ant-1.9.4/bin
launchctl setenv PATH $PATH

NOTE: without restart/log out and log in you can apply these changes using;

source ~/.bash_profile

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

It means that you should not share an iterator object among multiple threads. Creating multiple iterators and using them concurrently in separate threads is fine.

Use the Bootstrap Customizer to generate a version of Bootstrap that has a taller navbar. The value you want to change is @navbar-height in the Navbar section.

Inspect your current implementation to see how tall your navbar is with the 50px brand image, and use that calculated height in the Customizer.

Well now will be different after angular 5:

{{ number | currency :'GBP':'symbol':'1.2-2' }}

You will get output from column value 9 to 26 as you have mentioned OFFSET as 8

BalusC gave a good description about the problem but it lacks a good end to end code that users can pick and test it for themselves.

Best practice is to always store date-time in UTC timezone in DB. Sql timestamp type does not have timezone info.

When writing datetime value to sql db

    //Convert the time into UTC and build Timestamp object.
    Timestamp ts = Timestamp.valueOf(LocalDateTime.now(ZoneId.of("UTC")));
    //use setTimestamp on preparedstatement
    preparedStatement.setTimestamp(1, ts);

When reading the value back from DB into java,

1. Read it as it is in java.sql.Timestamp type.
2. Decorate the DateTime value as time in UTC timezone using atZone method in LocalDateTime class.

3. Then, change it to your desired timezone. Here I am changing it to Toronto timezone.

   ResultSet resultSet = preparedStatement.executeQuery();
   resultSet.next();
   Timestamp timestamp = resultSet.getTimestamp(1);
   ZonedDateTime timeInUTC = timestamp.toLocalDateTime().atZone(ZoneId.of("UTC"));
   LocalDateTime timeInToronto = LocalDateTime.ofInstant(timeInUTC.toInstant(), ZoneId.of("America/Toronto"));
   

I assume you are using Series.plot() to plot your data. If you look at the docs for Series.plot() here:

http://pandas.pydata.org/pandas-docs/dev/generated/pandas.Series.plot.html

there is no color parameter listed where you might be able to set the colors for your bar graph.

However, the Series.plot() docs state the following at the end of the parameter list:

kwds : keywords
Options to pass to matplotlib plotting method

What that means is that when you specify the kind argument for Series.plot() as bar, Series.plot() will actually call matplotlib.pyplot.bar(), and matplotlib.pyplot.bar() will be sent all the extra keyword arguments that you specify at the end of the argument list for Series.plot().

If you examine the docs for the matplotlib.pyplot.bar() method here:

http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.bar

..it also accepts keyword arguments at the end of it's parameter list, and if you peruse the list of recognized parameter names, one of them is color, which can be a sequence specifying the different colors for your bar graph.

Putting it all together, if you specify the color keyword argument at the end of your Series.plot() argument list, the keyword argument will be relayed to the matplotlib.pyplot.bar() method. Here is the proof:

import pandas as pd
import matplotlib.pyplot as plt

s = pd.Series(
    [5, 4, 4, 1, 12],
    index = ["AK", "AX", "GA", "SQ", "WN"]
)

#Set descriptions:
plt.title("Total Delay Incident Caused by Carrier")
plt.ylabel('Delay Incident')
plt.xlabel('Carrier')

#Set tick colors:
ax = plt.gca()
ax.tick_params(axis='x', colors='blue')
ax.tick_params(axis='y', colors='red')

#Plot the data:
my_colors = 'rgbkymc'  #red, green, blue, black, etc.

pd.Series.plot(
    s, 
    kind='bar', 
    color=my_colors,
)

plt.show()

Note that if there are more bars than colors in your sequence, the colors will repeat.

You might like to consider ADO - a worksheet or range can be used as a table.

Const adOpenStatic = 3
Const adLockOptimistic = 3
Const adPersistXML = 1

Set cn = CreateObject("ADODB.Connection")
Set rs = CreateObject("ADODB.Recordset")

''It wuld probably be better to use the proper name, but this is
''convenient for notes
strFile = Workbooks(1).FullName

''Note HDR=Yes, so you can use the names in the first row of the set
''to refer to columns, note also that you will need a different connection
''string for >=2007
strCon = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strFile _
        & ";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1"";"


cn.Open strCon
rs.Open "Select * from [Sheet1$]", cn, adOpenStatic, adLockOptimistic

If Not rs.EOF Then
    rs.MoveFirst
    rs.Save "C:\Docs\Table1.xml", adPersistXML
End If

rs.Close
cn.Close

Try:

System.getProperty("os.name");

Thanks for this code :) I really appreciate it. Works for me.

public static string connStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0;";

So if you have diff version of Excel file, get the file name, if its extension is .xlsx, use this:

Private Const connstring As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0;";

and if it is .xls, use:

Private Const connstring As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=" + path + ";Extended Properties=""Excel 8.0;HDR=YES;"""

Change your Ands to AndAlsos

A standard And will test both expressions. If comp.Container is Nothing, then the second expression will raise a NullReferenceException because you're accessing a property on a null object.

AndAlso will short-circuit the logical evaluation. If comp.Container is Nothing, then the 2nd expression will not be evaluated.

The problem is insufficient memory to load context.

Try to set VM options:

-da -Xmx2048m -Xms1024m -XX:MaxPermSize=2048m

For what it is worth: I was experiencing a similar issue trying to update a MySQL table via Perl. The update would fail when an empty string value (translated from a null value from a read from another platform) was passed to the date column ('dtcol' in the code sample below). I was finally successful getting the data updated by using an IF statement embedded in my update statement:

    ...
    my $stmnt='update tbl set colA=?,dtcol=if(?="",null,?) where colC=?';
    my $status=$dbh->do($stmt,undef,$iref[1],$iref[2],$iref[2],$ref[0]);
    ...

Best aproach for me was:

  private void grid_receptie_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
    {
        int X = 1;
        foreach(DataGridViewRow row in grid_receptie.Rows)
        {
            row.Cells["NR_CRT"].Value = X;
            X++;
        }
    }

Use time.mktime() to convert the time tuple (in localtime) into seconds since the Epoch, then use datetime.fromtimestamp() to get the datetime object.

from datetime import datetime
from time import mktime

dt = datetime.fromtimestamp(mktime(struct))

furthermore from Hazhir imput, for this issue is necessary inject that property in the checkbox xml configuration android:paddingLeft="0dp", this is for avoid the empty space at the checkbox left side.

Postman doesn't do that but you can run multiple curl requests asynchronously in Bash:

curl url1 & curl url2 & curl url3 & ...

Remember to add an & after each request which means that request should run as an async job.

Postman however can generate curl snippet for your request: https://learning.getpostman.com/docs/postman/sending_api_requests/generate_code_snippets/

Unless there is a specific optimization that checks if the argument passed to removeAll() is the collection itself (and I highly doubt that such an optimization is there) it will be significantly slower than a simple .clear().

Apart from that (and at least equally important): arraylist.removeAll(arraylist) is just obtuse, confusing code. It is a very backwards way of saying "clear this collection". What advantage would it have over the very understandable arraylist.clear()?

You have to tell Spring what input content-type is supported by your service. You can do this with the "consumes" Annotation Element that corresponds to your request's "Content-Type" header.

@RequestMapping(value = "/", method = RequestMethod.POST, consumes = {"application/x-www-form-urlencoded"})

It would be helpful if you posted your code.

This can be very easily accomplished using parse_str and parse_url and is more reliable in my opinion.

My function supports the following urls:

• http://youtube.com/v/dQw4w9WgXcQ?feature=youtube_gdata_player
• http://youtube.com/vi/dQw4w9WgXcQ?feature=youtube_gdata_player
• http://youtube.com/?v=dQw4w9WgXcQ&feature=youtube_gdata_player
• http://www.youtube.com/watch?v=dQw4w9WgXcQ&feature=youtube_gdata_player
• http://youtube.com/?vi=dQw4w9WgXcQ&feature=youtube_gdata_player
• http://youtube.com/watch?v=dQw4w9WgXcQ&feature=youtube_gdata_player
• http://youtube.com/watch?vi=dQw4w9WgXcQ&feature=youtube_gdata_player
• http://youtu.be/dQw4w9WgXcQ?feature=youtube_gdata_player

Also includes the test below the function.

/**
 * Get Youtube video ID from URL
 *
 * @param string $url
 * @return mixed Youtube video ID or FALSE if not found
 */
function getYoutubeIdFromUrl($url) {
    $parts = parse_url($url);
    if(isset($parts['query'])){
        parse_str($parts['query'], $qs);
        if(isset($qs['v'])){
            return $qs['v'];
        }else if(isset($qs['vi'])){
            return $qs['vi'];
        }
    }
    if(isset($parts['path'])){
        $path = explode('/', trim($parts['path'], '/'));
        return $path[count($path)-1];
    }
    return false;
}
// Test
$urls = array(
    'http://youtube.com/v/dQw4w9WgXcQ?feature=youtube_gdata_player',
    'http://youtube.com/vi/dQw4w9WgXcQ?feature=youtube_gdata_player',
    'http://youtube.com/?v=dQw4w9WgXcQ&feature=youtube_gdata_player',
    'http://www.youtube.com/watch?v=dQw4w9WgXcQ&feature=youtube_gdata_player',
    'http://youtube.com/?vi=dQw4w9WgXcQ&feature=youtube_gdata_player',
    'http://youtube.com/watch?v=dQw4w9WgXcQ&feature=youtube_gdata_player',
    'http://youtube.com/watch?vi=dQw4w9WgXcQ&feature=youtube_gdata_player',
    'http://youtu.be/dQw4w9WgXcQ?feature=youtube_gdata_player'
);
foreach($urls as $url){
    echo $url . ' : ' . getYoutubeIdFromUrl($url) . "\n";
}

Another answer, because jQuery.transit is not compatible with jQuery.easing. This solution comes as an jQuery extension. Is more generic, rotation is a specific case:

$.fn.extend({
    animateStep: function(options) {
        return this.each(function() {
            var elementOptions = $.extend({}, options, {step: options.step.bind($(this))});
            $({x: options.from}).animate({x: options.to}, elementOptions);
        });
    },
    rotate: function(value) {
        return this.css("transform", "rotate(" + value + "deg)");
    }
});

The usage is as simple as:

$(element).animateStep({from: 0, to: 90, step: $.fn.rotate});

Functional programming is about creating side-effect-free code.

map is a functional list transformation abstraction. You use it to take a sequence of something and turn it into a sequence of something else.

You are trying to use it as an iterator. Don't do that. :)

Here is an example of how you might use map to build the list you want. There are shorter solutions (I'd just use comprehensions), but this will help you understand what map does a bit better:

def my_transform_function(input):
    return [input, [1, 2, 3]]

new_list = map(my_transform, input_list)

Notice at this point, you've only done a data manipulation. Now you can print it:

for n,l in new_list:
    print n, ll

-- I'm not sure what you mean by 'without loops.' fp isn't about avoiding loops (you can't examine every item in a list without visiting each one). It's about avoiding side-effects, thus writing fewer bugs.

Have you verified that there is in fact a row where Staff_Id = @PersonID? What you've posted works fine in a test script, assuming the row exists. If you comment out the insert statement, then the error is raised.

set nocount on

create table Timesheet_Hours (Staff_Id int, BookedHours int, Posted_Flag bit)

insert into Timesheet_Hours (Staff_Id, BookedHours, Posted_Flag) values (1, 5.5, 0)

declare @PersonID int
set @PersonID = 1

IF EXISTS    
    (
    SELECT 1    
    FROM Timesheet_Hours    
    WHERE Posted_Flag = 1    
        AND Staff_Id = @PersonID    
    )    
    BEGIN
        RAISERROR('Timesheets have already been posted!', 16, 1)
        ROLLBACK TRAN
    END
ELSE
    IF NOT EXISTS
        (
        SELECT 1
        FROM Timesheet_Hours
        WHERE Staff_Id = @PersonID
        )
        BEGIN
            RAISERROR('Default list has not been loaded!', 16, 1)
            ROLLBACK TRAN
        END
    ELSE
        print 'No problems here'

drop table Timesheet_Hours

I also enounter this problem. In my environment, I use a tomcat as server and android as client. I found, If tomcat is started, this error " Launch error: Failed to connect to remote VM. Connection timed out." will occur. If tomcat is not run, adb works well.

Sometimes, it can be good to test private declarations. Fundamentally, a compiler only has one public method: Compile( string outputFileName, params string[] sourceSFileNames ). I'm sure you understand that would be difficult to test such a method without testing each "hidden" declarations!

That's why we have created Visual T#: to make easier tests. It's a free .NET programming language (C# v2.0 compatible).

We have added '.-' operator. It just behave like '.' operator, except you can also access any hidden declaration from your tests without changing anything in your tested project.

Take a look at our web site: download it for free.

here you need to skip int 0 like following:

val = s.nextInt();
  if ((val < min) && (val!=0)) {
      min = val;
  }

Your select doesn't have an ID, only a name. You'll need to modify your selector:

$("#pizza").on("click", function(){
  $("select[name='pizza_kind']").prop("disabled", !this.checked);
});

Desktop: first-class support

Oracle JavaFX from Java SE supports only OS X (macOS), GNU/Linux and Microsoft Windows. On these platforms, JavaFX applications are typically run on JVM from Java SE or OpenJDK.

Android: should work

There is also a JavaFXPorts project, which is an open-source project sponsored by a third-party. It aims to port JavaFX library to Android and iOS.

On Android, this library can be used like any other Java library; the JVM bytecode is compiled to Dalvik bytecode. It's what people mean by saying that "Android runs Java".

iOS: status not clear

On iOS, situation is a bit more complex, as neither Java SE nor OpenJDK supports Apple mobile devices. Till recently, the only sensible option was to use RoboVM ahead-of-time Java compiler for iOS. Unfortunately, on 15 April 2015, RoboVM project was shut down.

One possible alternative is Intel's Multi-OS Engine. Till recently, it was a proprietary technology, but on 11 August 2016 it was open-sourced. Although it can be possible to compile an iOS JavaFX app using JavaFXPorts' JavaFX implementation, there is no evidence for that so far. As you can see, the situation is dynamically changing, and this answer will be hopefully updated when new information is available.

Windows Phone: no support

With Windows Phone it's simple: there is no JavaFX support of any kind.

If you are using windows, Hyper-V works via AMD not HAXM.

Try the following: on Android, Click SDK Manager ==>SDK Platforms ==> Show Packages ==>ARM EABI v7a Systems Image.

After downloading the systems image, go to the AVD Manager ==> Create Virtual Device ==> choose device (e.g. 5.4 FWVGA") ==> Marshmallow armeabi v7a Android6 with Google APIs ==> Change the AVD name to anything (eg. myfirst)==> click finish.

If, while using the mysql_upgrade -u root -p --force command You get this error:

Could not create the upgrade info file '/var/lib/mysql/mysql_upgrade_info' in the MySQL Servers datadir, errno: 13

just add the sudo before the command. That worked for me, and I solved my problem. So, it's: sudo mysql_upgrade -u root -p --force :)

If it's open to a modification, you could use a suffix instead of a prefix. Then you could use tab-completion to get the original filename and add the suffix.

Otherwise, no this isn't something that is supported by the mv command. A simple shell script could cope though.

They probably compile down to nearly the same machine code, so it is a matter of taste.

Personally, I would chose the one that is the clearest (i.e. very clear that it is supposed to be an infinite loop).

I would lean towards while(true){}.

No, there's no direct not operator. At least not the way you hope for.

You can use a zero-width negative lookahead, however:

\((?!2001)[0-9a-zA-z _\.\-:]*\)

The (?!...) part means "only match if the text following (hence: lookahead) this doesn't (hence: negative) match this. But it doesn't actually consume the characters it matches (hence: zero-width).

There are actually 4 combinations of lookarounds with 2 axes:

• lookbehind / lookahead : specifies if the characters before or after the point are considered
• positive / negative : specifies if the characters must match or must not match.

>>> type(cow[0])
<class 'int'>
>>> 
>>> type(0)
<class 'int'>

There is two way for hide a element

1. Use the "hidden" html attribute But in angular you can bind it with one or more fields like this :

   <input class="txt" type="password" [(ngModel)]="input_pw" [hidden]="isHidden">

2.Better way of doing this is to use " *ngIf " directive like this :

<input class="txt" type="password" [(ngModel)]="input_pw" *ngIf="!isHidden">

Now why this is a better way because it doesn't just hide the element, it will removes it from the html code so this will help your page to render.

I have written a piece of code that puts the command line arguments in the format that gradle expects.

// this method creates a command line arguments
def setCommandLineArguments(commandLineArgs) {
    // remove spaces 
    def arguments = commandLineArgs.tokenize()

            // create a string that can be used by Eval 
            def cla = "["
            // go through the list to get each argument
            arguments.each {
                    cla += "'" + "${it}" + "',"
            }

    // remove last "," add "]" and set the args 
    return cla.substring(0, cla.lastIndexOf(',')) + "]"
}

my task looks like this:

task runProgram(type: JavaExec) {
    if ( project.hasProperty("commandLineArgs") ) {
            args Eval.me( setCommandLineArguments(commandLineArgs) )
    }
}

To pass the arguments from the command line you run this:

gradle runProgram -PcommandLineArgs="arg1 arg2 arg3 arg4"    

If you're into jQuery, there is a good query string manipulation plugin:

You may want to try out simple function I posted on another thread related to reading date value from excel sheet.

It simply takes text from the cell as input and gives DateTime as output.

I would be happy to see improvement in my sample code provided for benefit of the .Net development community.

Here is the link for the thread C# not reading excel date from spreadsheet

The following code will write an image in proportional to the response, you can modify the code for your purpose:

public void WriteImage(string path, int width, int height)
{
    Bitmap srcBmp = new Bitmap(path);
    float ratio = srcBmp.Width / srcBmp.Height;
    SizeF newSize = new SizeF(width, height * ratio);
    Bitmap target = new Bitmap((int) newSize.Width,(int) newSize.Height);
    HttpContext.Response.Clear();
    HttpContext.Response.ContentType = "image/jpeg";
    using (Graphics graphics = Graphics.FromImage(target))
    {
        graphics.CompositingQuality = CompositingQuality.HighSpeed;
        graphics.InterpolationMode = InterpolationMode.HighQualityBicubic;
        graphics.CompositingMode = CompositingMode.SourceCopy;
        graphics.DrawImage(srcBmp, 0, 0, newSize.Width, newSize.Height);
        using (MemoryStream memoryStream = new MemoryStream()) 
        {
            target.Save(memoryStream, ImageFormat.Jpeg);
            memoryStream.WriteTo(HttpContext.Response.OutputStream);
        }
    }
    Response.End();
}

Use chr() and ord():

In case you are using eclipse to connect oracle without SID. There are two drivers to select i.e., Oracle thin driver and other is other driver. Select other drivers and enter service name in database column. Now you can connect directly using service name without SID.

Here's one way in XSLT 2

<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;','''')"/>   </xsl:template> </xsl:stylesheet> 

Doing it in XSLT1 is a little more problematic as it's hard to get a literal containing a single apostrophe, so you have to resort to a variable:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:variable name="apos">'</xsl:variable>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;',$apos)"/>   </xsl:template> </xsl:stylesheet> 

Referencing Steven Penny's answer, it's best to create a test branch and test the PR. So here's what you would do.

1. Create a test branch to merge the PR into locally. Assuming you're on the master branch:

git checkout -b test

2. Get the PR changes into the test branch

git pull origin pull/939/head:test

Now, you can safely test the changes on this local test branch (in this case, named test) and once you're satisfied, can merge it as usual from GitHub.

Here is a directive to have actions programmed after a shallow render. By shallow I mean it will evaluate after that very element rendered and that will be unrelated to when its contents get rendered. So if you need some sub element doing a post render action, you should consider using it there:

define(['angular'], function (angular) {
  'use strict';
  return angular.module('app.common.after-render', [])
    .directive('afterRender', [ '$timeout', function($timeout) {
    var def = {
        restrict : 'A', 
        terminal : true,
        transclude : false,
        link : function(scope, element, attrs) {
            if (attrs) { scope.$eval(attrs.afterRender) }
            scope.$emit('onAfterRender')
        }
    };
    return def;
    }]);
});

then you can do:

<div after-render></div>

or with any useful expression like:

<div after-render="$emit='onAfterThisConcreteThingRendered'"></div>

• The children of a row-flexbox container automatically fill the container's vertical space.

• Specify flex: 1; for a child if you want it to fill the remaining horizontal space:

.wrapper {_x000D_
  display: flex;_x000D_
  flex-direction: row;_x000D_
  align-items: stretch;_x000D_
  width: 100%;_x000D_

}

<div class="wrapper">_x000D_
  <div class="left">Left</div>_x000D_
  <div class="right">Right</div>_x000D_
</div>

• Specify flex: 1; for both children if you want them to fill equal amounts of the horizontal space:

.wrapper {_x000D_
  display: flex;_x000D_
  flex-direction: row;_x000D_
  align-items: stretch;_x000D_
  width: 100%;_x000D_

A way to use a custom sort function

//func has to return 0 in the case in which they are equal
sort_unique = function(arr,func) {
        func = func || function (a, b) {
            return a*1 - b*1;
        };
        arr = arr.sort(func);
        var ret = [arr[0]];
        for (var i = 1; i < arr.length; i++) {
            if (func(arr[i-1],arr[i]) != 0) 
                ret.push(arr[i]);
            }
        }
        return ret;
    }

Example: desc order for an array of objects

MyArray = sort_unique(MyArray , function(a,b){
            return  b.iterator_internal*1 - a.iterator_internal*1;
        });

mysql -h "hostname" -u usr_name -pPASSWD "db_name" < sql_script_file

(use full path for sql_script_file if needed)

If you want to redirect the out put to a file

mysql -h "hostname" -u usr_name -pPASSWD "db_name" < sql_script_file > out_file

Are you including "stdlib.h" or "cstdlib" in this file? NULL is defined in stdlib.h/cstdlib

#include <stdlib.h>

or

#include <cstdlib>  // This is preferrable for c++

Here's the answer from Apple's official documentation, just tried, it's working.

Setting the Bundle ID

The default bundle ID in your Xcode project is a string formatted as a reverse-domain—for example, com.MyCompany.MyProductName. To create the default bundle ID, Xcode concatenates the company identifier with the product name you entered when creating the project from a template, as described in Setting Properties When Creating Your Xcode Project. (Xcode replaces spaces in the product name to create the default bundle ID.) It may be sufficient to replace the company identifier prefix in the bundle ID or you can replace the entire bundle ID. For example, change the company identifier prefix to match your company domain name or replace the entire bundle ID to match an explicit App ID.

For Mac apps, ensure that every bundle ID is unique within your app bundle. For example, if your app bundle includes a helper app, ensure that its bundle ID is different from your app’s bundle ID.

Follow these steps to change the bundle ID prefix in the General pane in the project editor.

To set the bundle ID prefix

1. In the project navigator, select the project and your target to display the project editor.

2. Click General and, if necessary, click the disclosure triangle next to Identity to reveal the settings.

3. Enter the bundle ID prefix in the “Bundle Identifier” field.

To set the bundle ID

1. In the project navigator, select the project and your target to display the project editor.

2. Click Info.

3. Enter the bundle ID in the Value column of the “Bundle identifier” row.

To convert from integers < 256 to binary, use the chr function. So you're looking at doing the following.

newFileBytes=[123,3,255,0,100]
newfile=open(path,'wb')
newfile.write((''.join(chr(i) for i in newFileBytes)).encode('charmap'))

public static <E> E[] appendToArray(E[] array, E item) { ...

Note the <E>.

Static generic methods need their own generic declaration (public static <E>) separate from the class's generic declaration (public class ArrayUtils<E>).

If the compiler complains about a type ambiguity in invoking a static generic method (again not likely in your case, but, generally speaking, just in case), here's how to explicitly invoke a static generic method using a specific type (_class_.<_generictypeparams_>_methodname_):

String[] newStrings = ArrayUtils.<String>appendToArray(strings, "another string");

This would only happen if the compiler can't determine the generic type because, e.g. the generic type isn't related to the method arguments.

It's simple :

Let's imagine that you are trying to upload a file within js framework, ajax request or mobile application (Client side)

1. Firstly you send a data attribute that contains a base64 encoded string.
2. In the server side you have to decode it and save it in a local project folder.

Here how to do it using PHP

<?php 

$base64String = "kfezyufgzefhzefjizjfzfzefzefhuze"; // I put a static base64 string, you can implement you special code to retrieve the data received via the request.

$filePath = "/MyProject/public/uploads/img/test.png";

file_put_contents($filePath, base64_decode($base64String));

?>

If you want add Custom method you can do it

(in this case, at least one checkbox selected)

<input class="checkBox" type="checkbox" id="i0000zxthy" name="i0000zxthy"  value="1" onclick="test($(this))"/>

in Javascript

var tags = 0;

$(document).ready(function() {   

    $.validator.addMethod('arrayminimo', function(value) {
        return tags > 0
    }, 'Selezionare almeno un Opzione');

    $.validator.addClassRules('check_secondario', {
        arrayminimo: true,

    });

    validaFormRichiesta();
});

function validaFormRichiesta() {
    $("#form").validate({
        ......
    });
}

function test(n) {
    if (n.prop("checked")) {
        tags++;
    } else {
        tags--;
    }
}

Replace session_start(); with:

if (!isset($a)) {
    a = False;
    if ($a == TRUE) {
        session_start();
        $a = TRUE;
    }
}

You can also do this by passing function with onclick event

<a onclick="getColor(this);" color="red">

<script type="text/javascript">

function getColor(el)
{
     color = $(el).attr('color');
     alert(color);
}

</script> 

You have to install Microsoft.Bcl.Async NuGet package to be able to use async/await constructs in pre-.NET 4.5 versions (such as Silverlight 4.0+)

If you change .bash_profile, it only applies to new Terminal sessions.

To apply it to an existing session, run source ~/.bash_profile. You can run any Bash script this way - think of executing source as the same as typing commands in the Terminal window (from the specified script).

Bonus: You can make environment variables available to OSX applications - not just the current Bash session but apps like Visual Studio Code or IntelliJ - using launchctl setenv GOPATH "${GOPATH:-}"

What is load factor ?

The amount of capacity which is to be exhausted for the HashMap to increase its capacity ?

Why load factor ?

Load factor is by default 0.75 of the initial capacity (16) therefore 25% of the buckets will be free before there is an increase in the capacity & this makes many new buckets with new hashcodes pointing to them to exist just after the increase in the number of buckets.

Now why should you keep many free buckets & what is the impact of keeping free buckets on the performance ?

If you set the loading factor to say 1.0 then something very interesting might happen.

Say you are adding an object x to your hashmap whose hashCode is 888 & in your hashmap the bucket representing the hashcode is free , so the object x gets added to the bucket, but now again say if you are adding another object y whose hashCode is also 888 then your object y will get added for sure BUT at the end of the bucket (because the buckets are nothing but linkedList implementation storing key,value & next) now this has a performance impact ! Since your object y is no longer present in the head of the bucket if you perform a lookup the time taken is not going to be O(1) this time it depends on how many items are there in the same bucket. This is called hash collision by the way & this even happens when your loading factor is less than 1.

Correlation between performance , hash collision & loading factor ?

Lower load factor = more free buckets = less chances of collision = high performance = high space requirement.

Correct me if i am wrong somewhere.

step 1: add

<asp:FileUpload runat="server" id="fileUpload1" Multiple="Multiple">
    </asp:FileUpload>

step 2: add

Protected Sub uploadBtn_Click(sender As Object, e As System.EventArgs) Handles uploadBtn.Click
    Dim ImageFiles As HttpFileCollection = Request.Files
    For i As Integer = 0 To ImageFiles.Count - 1
        Dim file As HttpPostedFile = ImageFiles(i)
        file.SaveAs(Server.MapPath("Uploads/") & ImageFiles(i).FileName)
    Next

var focused = true;

window.onfocus = function() {
    focused = true;

One trick that makes position:absolute more palatable to me is to make its parent position:relative. Then the child will be 'absolute' relative to the position of the parent.

You could iterate on a copy (clone) of your original list:

List<String> copy = new ArrayList<String>(list);
for (String s : copy) {
    // And if you have to add an element to the list, add it to the original one:
    list.add("some element");
}

Note that it is not even possible to add a new element to a list while iterating on it, because it will result in a ConcurrentModificationException.

This is easy.

tell .gitignore to ignore everything except .gitignore and the folders you want to keep. Put .gitignore into folders that you want to keep in the repo.

Contents of the top-most .gitignore:

# ignore everything except .gitignore and folders that I care about:
*
!images*
!.gitignore

In the nested images folder this is your .gitignore:

# ignore everything except .gitignore
*
!.gitignore

Note, you must spell out in the .gitignore the names of the folders you don't want to be ignored in the folder where that .gitignore is located. Otherwise they are, obviously, ignored.

Your folders in the repo will, obviously, NOT be empty, as each one will have .gitignore in it, but that part can be ignored, right. :)

Wait and await - while similar conceptually - are actually completely different.

Wait will synchronously block until the task completes. So the current thread is literally blocked waiting for the task to complete. As a general rule, you should use "async all the way down"; that is, don't block on async code. On my blog, I go into the details of how blocking in asynchronous code causes deadlock.

await will asynchronously wait until the task completes. This means the current method is "paused" (its state is captured) and the method returns an incomplete task to its caller. Later, when the await expression completes, the remainder of the method is scheduled as a continuation.

You also mentioned a "cooperative block", by which I assume you mean a task that you're Waiting on may execute on the waiting thread. There are situations where this can happen, but it's an optimization. There are many situations where it can't happen, like if the task is for another scheduler, or if it's already started or if it's a non-code task (such as in your code example: Wait cannot execute the Delay task inline because there's no code for it).

You may find my async / await intro helpful.

You can do it programmatically:

grid0.Columns[0].Visible = true;
grid0.DataSource = dt;
grid0.DataBind();
grid0.Columns[0].Visible = false;

In this way you set the column to visible before databinding, so the column is generated. The you set the column to not visible, so it is not displayed.

Try using the @ symbol before the url string. Import your css in the following manner:

import Vue from 'vue'

require('@/assets/styles/main.css')

In your App.vue file you can do this to import a css file in the style tag

  <div>
  </div>
</template>

<style scoped src="@/assets/styles/mystyles.css">
</style>

You JSON doesn't match your struct fields: E.g. "district" in JSON and "District" as the field.

also you can export it like this

const func1 = function (){some code here}
const func2 = function (){some code here}
exports.func1 = func1;
exports.func2 = func2;

or for anonymous functions like this

    const func1 = ()=>{some code here}
    const func2 = ()=>{some code here}
    exports.func1 = func1;
    exports.func2 = func2;

You can stash (save the changes in temporary box) then, back to master branch HEAD.

$ git add .
$ git stash
$ git checkout master

Jump Over Commits Back and Forth:

• Go to a specific commit-sha.

    $ git checkout <commit-sha>
  

• If you have uncommitted changes here then, you can checkout to a new branch | Add | Commit | Push the current branch to the remote.

    # checkout a new branch, add, commit, push
    $ git checkout -b <branch-name>
    $ git add .
    $ git commit -m 'Commit message'
    $ git push origin HEAD          # push the current branch to remote 
  
    $ git checkout master           # back to master branch now
  

• If you have changes in the specific commit and don't want to keep the changes, you can do stash or reset then checkout to master (or, any other branch).

    # stash
    $ git add -A
    $ git stash
    $ git checkout master
  
    # reset
    $ git reset --hard HEAD
    $ git checkout master
  

• After checking out a specific commit if you have no uncommitted change(s) then, just back to master or other branch.

    $ git status          # see the changes
    $ git checkout master
  
    # or, shortcut
    $ git checkout -      # back to the previous state
  

Blob URLs (ref W3C, official name) or Object-URLs (ref. MDN and method name) are used with a Blob or a File object.

src="blob:https://crap.crap" I opened the blob url that was in src of video it gave a error and i can't open but was working with the src tag how it is possible?

Blob URLs can only be generated internally by the browser. URL.createObjectURL() will create a special reference to the Blob or File object which later can be released using URL.revokeObjectURL(). These URLs can only be used locally in the single instance of the browser and in the same session (ie. the life of the page/document).

What is blob url?
Why it is used?

Blob URL/Object URL is a pseudo protocol to allow Blob and File objects to be used as URL source for things like images, download links for binary data and so forth.

For example, you can not hand an Image object raw byte-data as it would not know what to do with it. It requires for example images (which are binary data) to be loaded via URLs. This applies to anything that require an URL as source. Instead of uploading the binary data, then serve it back via an URL it is better to use an extra local step to be able to access the data directly without going via a server.

It is also a better alternative to Data-URI which are strings encoded as Base-64. The problem with Data-URI is that each char takes two bytes in JavaScript. On top of that a 33% is added due to the Base-64 encoding. Blobs are pure binary byte-arrays which does not have any significant overhead as Data-URI does, which makes them faster and smaller to handle.

Can i make my own blob url on a server?

No, Blob URLs/Object URLs can only be made internally in the browser. You can make Blobs and get File object via the File Reader API, although BLOB just means Binary Large OBject and is stored as byte-arrays. A client can request the data to be sent as either ArrayBuffer or as a Blob. The server should send the data as pure binary data. Databases often uses Blob to describe binary objects as well, and in essence we are talking basically about byte-arrays.

if you have then Additional detail

You need to encapsulate the binary data as a BLOB object, then use URL.createObjectURL() to generate a local URL for it:

var blob = new Blob([arrayBufferWithPNG], {type: "image/png"}),
    url = URL.createObjectURL(blob),
    img = new Image();

img.onload = function() {
    URL.revokeObjectURL(this.src);     // clean-up memory
    document.body.appendChild(this);   // add image to DOM
}

img.src = url;                         // can now "stream" the bytes

Note that URL may be prefixed in webkit-browsers, so use:

var url = (URL || webkitURL).createObjectURL(...);

int *a[], when used as a function parameter (but not in normal declarations), is a pointer to a pointer, not a pointer to an array (in normal declarations, it is an array of pointers). A pointer to an array looks like this:

int (*aptr)[N]

Where N is a particular positive integer (not a variable).

If you make your function a template, you can do it and you don't even need to pass the size of the array (because it is automatically deduced):

template<size_t SZ>
void generateArray(int (*aptr)[SZ])
{
    for (size_t i=0; i<SZ; ++i)
        (*aptr)[i] = rand() % 9;
}

int main()
{    
    int a[5];    
    generateArray(&a);
}

You could also take a reference:

template<size_t SZ>
void generateArray(int (&arr)[SZ])
{
    for (size_t i=0; i<SZ; ++i)
        arr[i] = rand() % 9;
}

int main()
{    
    int a[5];    
    generateArray(a);
}

The following should do what you want.

I learned that you can either use the provisional jquery method to clear it first then append:

Or conventionaly, you could use:

$("#LabelID").text("some value");

OR

$("#LabelID").html("some value");

I had this same problem and discovered (via this answer to a similar question) that the problem was that I didn't properly indent the docstring properly. Unfortunately IDLE doesn't give useful feedback here, but once I fixed the docstring indentation, the problem went away.

Specifically --- bad code that generates indentation errors:

def my_function(args):
"Here is my docstring"
    ....

Good code that avoids indentation errors:

def my_function(args):
    "Here is my docstring"
    ....

Note: I'm not saying this is the problem, but that it might be, because in my case, it was!

Exported variables such as $HOME and $PATH are available to (inherited by) other programs run by the shell that exports them (and the programs run by those other programs, and so on) as environment variables. Regular (non-exported) variables are not available to other programs.

$ env | grep '^variable='
$                                 # No environment variable called variable
$ variable=Hello                  # Create local (non-exported) variable with value
$ env | grep '^variable='
$                                 # Still no environment variable called variable
$ export variable                 # Mark variable for export to child processes
$ env | grep '^variable='
variable=Hello
$
$ export other_variable=Goodbye   # create and initialize exported variable
$ env | grep '^other_variable='
other_variable=Goodbye
$

For more information, see the entry for the export builtin in the GNU Bash manual, and also the sections on command execution environment and environment.

Note that non-exported variables will be available to subshells run via ( ... ) and similar notations because those subshells are direct clones of the main shell:

$ othervar=present
$ (echo $othervar; echo $variable; variable=elephant; echo $variable)
present
Hello
elephant
$ echo $variable
Hello
$

The subshell can change its own copy of any variable, exported or not, and may affect the values seen by the processes it runs, but the subshell's changes cannot affect the variable in the parent shell, of course.

Some information about subshells can be found under command grouping and command execution environment in the Bash manual.

It seems in general you're just looking for a join:

> dat1 = pd.DataFrame({'dat1': [9,5]})
> dat2 = pd.DataFrame({'dat2': [7,6]})
> dat1.join(dat2)
   dat1  dat2
0     9     7
1     5     6

Took me a while to find this but note that if you have a spacing error you will also get the same error:

Correct:

vs

if ["$APP_ENV" = "staging" ]

As always setting -x debug variable helps to find these:

set -x

objectForKey: is an NSDictionary method. An NSDictionary is a collection class similar to an NSArray, except instead of using indexes, it uses keys to differentiate between items. A key is an arbitrary string you provide. No two objects can have the same key (just as no two objects in an NSArray can have the same index).

valueForKey: is a KVC method. It works with ANY class. valueForKey: allows you to access a property using a string for its name. So for instance, if I have an Account class with a property accountNumber, I can do the following:

NSNumber *anAccountNumber = [NSNumber numberWithInt:12345];
Account *newAccount = [[Account alloc] init];

[newAccount setAccountNumber:anAccountNUmber];

NSNumber *anotherAccountNumber = [newAccount accountNumber];

Using KVC, I can access the property dynamically:

NSNumber *anAccountNumber = [NSNumber numberWithInt:12345];
Account *newAccount = [[Account alloc] init];

[newAccount setValue:anAccountNumber forKey:@"accountNumber"];

NSNumber *anotherAccountNumber = [newAccount valueForKey:@"accountNumber"];

Those are equivalent sets of statements.

I know you're thinking: wow, but sarcastically. KVC doesn't look all that useful. In fact, it looks "wordy". But when you want to change things at runtime, you can do lots of cool things that are much more difficult in other languages (but this is beyond the scope of your question).

If you want to learn more about KVC, there are many tutorials if you Google especially at Scott Stevenson's blog. You can also check out the NSKeyValueCoding Protocol Reference.

Hope that helps.

Take a peek at the ng-click directive source:

...
compile: function($element, attr) {
  var fn = $parse(attr[directiveName]);
  return function(scope, element, attr) {
    element.on(lowercase(name), function(event) {
      scope.$apply(function() {
        fn(scope, {$event:event});
      });
    });
  };
}

It shows how the event object is being passed on to the ng-click expression, using $event as a name of the parameter. This is done by the $parse service, which doesn't allow for the parameters to bleed into the target scope, which means the answer is no, you can't access the $event object any other way but through the callback parameter.

Here's an awfully complicated solution, but it works:

public static BigDecimal roundBigDecimal(final BigDecimal input){
    return input.round(
        new MathContext(
            input.toBigInteger().toString().length(),
            RoundingMode.HALF_UP
        )
    );
}

Test Code:

List<BigDecimal> bigDecimals =
    Arrays.asList(new BigDecimal("100.12"),
        new BigDecimal("100.44"),
        new BigDecimal("100.50"),
        new BigDecimal("100.75"));
for(final BigDecimal bd : bigDecimals){
    System.out.println(roundBigDecimal(bd).toPlainString());
}

Output:

jQuery solution

How do I get the text value of a selected option

Select elements typically have two values that you want to access.
First there's the value to be sent to the server, which is easy:

$( "#myselect" ).val();
// => 1

The second is the text value of the select.
For example, using the following select box:

<select id="myselect">
  <option value="1">Mr</option>
  <option value="2">Mrs</option>
  <option value="3">Ms</option>
  <option value="4">Dr</option>
  <option value="5">Prof</option>
</select>

If you wanted to get the string "Mr" if the first option was selected (instead of just "1") you would do that in the following way:

$( "#myselect option:selected" ).text();
// => "Mr"

If you are still using .NET 2.0, then [IO.Path]::Combine won't have the params string[] overload which you need to join more than two parts, and you'll see the error Cannot find an overload for "Combine" and the argument count: "3".

Slightly less elegant, but a pure PowerShell solution is to manually aggregate path parts:

Join-Path C: (Join-Path  "Program Files" "Microsoft Office")

or

Join-Path  (Join-Path  C: "Program Files") "Microsoft Office"

Command mvnw uses Maven that is by default downloaded to ~/.m2/wrapper on the first use.

URL with Maven is specified in each project at .mvn/wrapper/maven-wrapper.properties:

distributionUrl=https://repo1.maven.org/maven2/org/apache/maven/apache-maven/3.3.9/apache-maven-3.3.9-bin.zip

To update or change Maven version invoke the following (remember about --non-recursive for multi-module projects):

./mvnw io.takari:maven:wrapper -Dmaven=3.3.9 

or just modify .mvn/wrapper/maven-wrapper.properties manually.

To generate wrapper from scratch using Maven (you need to have it already in PATH run:

mvn io.takari:maven:wrapper -Dmaven=3.3.9 

Though late answer, but would like to add that one way to get this

LayoutInflater layoutInflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view = layoutInflater.inflate(R.layout.mylayout, item );

where item is the parent layout where you want to add a child layout.

One thing I didn't realize at first when reading the accepted answer was that making an inner class static is basically the same thing as moving it to its own separate class.

Thus, when getting the error

xxx is not an enclosing class

You can solve it in either of the following ways:

• Add the static keyword to the inner class, or
• Move it out to its own separate class.

Dapper now supports custom column to property mappers. It does so through the ITypeMap interface. A CustomPropertyTypeMap class is provided by Dapper that can do most of this work. For example:

Dapper.SqlMapper.SetTypeMap(
    typeof(TModel),
    new CustomPropertyTypeMap(
        typeof(TModel),
        (type, columnName) =>
            type.GetProperties().FirstOrDefault(prop =>
                prop.GetCustomAttributes(false)
                    .OfType<ColumnAttribute>()
                    .Any(attr => attr.Name == columnName))));

And the model:

public class TModel {
    [Column(Name="my_property")]
    public int MyProperty { get; set; }
}

It's important to note that the implementation of CustomPropertyTypeMap requires that the attribute exist and match one of the column names or the property won't be mapped. The DefaultTypeMap class provides the standard functionality and can be leveraged to change this behavior:

public class FallbackTypeMapper : SqlMapper.ITypeMap
{
    private readonly IEnumerable<SqlMapper.ITypeMap> _mappers;

    public FallbackTypeMapper(IEnumerable<SqlMapper.ITypeMap> mappers)
    {
        _mappers = mappers;
    }

    public SqlMapper.IMemberMap GetMember(string columnName)
    {
        foreach (var mapper in _mappers)
        {
            try
            {
                var result = mapper.GetMember(columnName);
                if (result != null)
                {
                    return result;
                }
            }
            catch (NotImplementedException nix)
            {
            // the CustomPropertyTypeMap only supports a no-args
            // constructor and throws a not implemented exception.
            // to work around that, catch and ignore.
            }
        }
        return null;
    }
    // implement other interface methods similarly

    // required sometime after version 1.13 of dapper
    public ConstructorInfo FindExplicitConstructor()
    {
        return _mappers
            .Select(mapper => mapper.FindExplicitConstructor())
            .FirstOrDefault(result => result != null);
    }
}

And with that in place, it becomes easy to create a custom type mapper that will automatically use the attributes if they're present but will otherwise fall back to standard behavior:

public class ColumnAttributeTypeMapper<T> : FallbackTypeMapper
{
    public ColumnAttributeTypeMapper()
        : base(new SqlMapper.ITypeMap[]
            {
                new CustomPropertyTypeMap(
                   typeof(T),
                   (type, columnName) =>
                       type.GetProperties().FirstOrDefault(prop =>
                           prop.GetCustomAttributes(false)
                               .OfType<ColumnAttribute>()
                               .Any(attr => attr.Name == columnName)
                           )
                   ),
                new DefaultTypeMap(typeof(T))
            })
    {
    }
}

That means we can now easily support types that require map using attributes:

Dapper.SqlMapper.SetTypeMap(
    typeof(MyModel),
    new ColumnAttributeTypeMapper<MyModel>());

Here's a Gist to the full source code.

You can use @JsonFormat annotation with shape as STRING on your BigDecimal variables. Refer below:

 import com.fasterxml.jackson.annotation.JsonFormat;

  class YourObjectClass {

      @JsonFormat(shape=JsonFormat.Shape.STRING)
      private BigDecimal yourVariable;

 }

If you use Node.JS, You can use the native Buffer module by doing :

const token = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiYWRtaW4iOnRydWUsImp0aSI6ImU3YjQ0Mjc4LTZlZDYtNDJlZC05MTZmLWFjZDQzNzhkM2U0YSIsImlhdCI6MTU5NTg3NzUxOCwiZXhwIjoxNTk1ODgxMTE4fQ.WXyDlDMMSJAjOFF9oAU9JrRHg2wio-WolWAkAaY3kg4';
const base64Url = token.split('.')[1];
const decoded = Buffer.from(base64Url, 'base64').toString();
console.log(decoded)

And you're good to go :-)

There are two ways that I know of to color plot points by factor and then also have a corresponding legend automatically generated. I'll give examples of both:

1. Using ggplot2 (generally easier)
2. Using R's built in plotting functionality in combination with the colorRampPallete function (trickier, but many people prefer/need R's built-in plotting facilities)

For both examples, I will use the ggplot2 diamonds dataset. We'll be using the numeric columns diamond$carat and diamond$price, and the factor/categorical column diamond$color. You can load the dataset with the following code if you have ggplot2 installed:

library(ggplot2)
data(diamonds)

Using ggplot2 and qplot

It's a one liner. Key item here is to give qplot the factor you want to color by as the color argument. qplot will make a legend for you by default.

qplot(
  x = carat,
  y = price,
  data = diamonds,
  color = diamonds$color # color by factor color (I know, confusing)
)

Your output should look like this:

Using R's built in plot functionality

Using R's built in plot functionality to get a plot colored by a factor and an associated legend is a 4-step process, and it's a little more technical than using ggplot2.

First, we will make a colorRampPallete function. colorRampPallete() returns a new function that will generate a list of colors. In the snippet below, calling color_pallet_function(5) would return a list of 5 colors on a scale from red to orange to blue:

color_pallete_function <- colorRampPalette(
  colors = c("red", "orange", "blue"),
  space = "Lab" # Option used when colors do not represent a quantitative scale
  )

Second, we need to make a list of colors, with exactly one color per diamond color. This is the mapping we will use both to assign colors to individual plot points, and to create our legend.

num_colors <- nlevels(diamonds$color)
diamond_color_colors <- color_pallet_function(num_colors)

Third, we create our plot. This is done just like any other plot you've likely done, except we refer to the list of colors we made as our col argument. As long as we always use this same list, our mapping between colors and diamond$colors will be consistent across our R script.

plot(
  x = diamonds$carat,
  y = diamonds$price,
  xlab = "Carat",
  ylab = "Price",
  pch = 20, # solid dots increase the readability of this data plot
  col = diamond_color_colors[diamonds$color]
)

Fourth and finally, we add our legend so that someone reading our graph can clearly see the mapping between the plot point colors and the actual diamond colors.

legend(
  x ="topleft",
  legend = paste("Color", levels(diamonds$color)), # for readability of legend
  col = diamond_color_colors,
  pch = 19, # same as pch=20, just smaller
  cex = .7 # scale the legend to look attractively sized
)

Your output should look like this:

Nifty, right?

How about this, a quick solution.

import requests

url = "http://craphound.com/images/1006884_2adf8fc7.jpg"
response = requests.get(url)
if response.status_code == 200:
    with open("/Users/apple/Desktop/sample.jpg", 'wb') as f:
        f.write(response.content)

This isn't really possible in HTML unless you use absolute positioning or javascript. So one solution would be to give this CSS to #bottom_link:

#bottom_link {
    position:absolute;
    bottom:0;
}

Otherwise you'd have to use some javascript. Here's a jQuery block that should do the trick, depending on the simplicity of the page.

$('#bottom_link').css({
    position: 'relative',
    top: $(this).parent().height() - $(this).height()
});

JUST THIS WORKS!!

You could replace the original jQuery addClass and removeClass functions with your own that would call the original functions and then trigger a custom event. (Using a self-invoking anonymous function to contain the original function reference)

(function( func ) {
    $.fn.addClass = function() { // replace the existing function on $.fn
        func.apply( this, arguments ); // invoke the original function
        this.trigger('classChanged'); // trigger the custom event
        return this; // retain jQuery chainability
    }
})($.fn.addClass); // pass the original function as an argument

(function( func ) {
    $.fn.removeClass = function() {
        func.apply( this, arguments );
        this.trigger('classChanged');
        return this;
    }
})($.fn.removeClass);

Then the rest of your code would be as simple as you'd expect.

$(selector).on('classChanged', function(){ /*...*/ });

Update:

This approach does make the assumption that the classes will only be changed via the jQuery addClass and removeClass methods. If classes are modified in other ways (such as direct manipulation of the class attribute through the DOM element) use of something like MutationObservers as explained in the accepted answer here would be necessary.

Also as a couple improvements to these methods:

• Trigger an event for each class being added (classAdded) or removed (classRemoved) with the specific class passed as an argument to the callback function and only triggered if the particular class was actually added (not present previously) or removed (was present previously)

• Only trigger classChanged if any classes are actually changed

  (function( func ) {
      $.fn.addClass = function(n) { // replace the existing function on $.fn
          this.each(function(i) { // for each element in the collection
              var $this = $(this); // 'this' is DOM element in this context
              var prevClasses = this.getAttribute('class'); // note its original classes
              var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString(); // retain function-type argument support
              $.each(classNames.split(/\s+/), function(index, className) { // allow for multiple classes being added
                  if( !$this.hasClass(className) ) { // only when the class is not already present
                      func.call( $this, className ); // invoke the original function to add the class
                      $this.trigger('classAdded', className); // trigger a classAdded event
                  }
              });
              prevClasses != this.getAttribute('class') && $this.trigger('classChanged'); // trigger the classChanged event
          });
          return this; // retain jQuery chainability
      }
  })($.fn.addClass); // pass the original function as an argument
  
  (function( func ) {
      $.fn.removeClass = function(n) {
          this.each(function(i) {
              var $this = $(this);
              var prevClasses = this.getAttribute('class');
              var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString();
              $.each(classNames.split(/\s+/), function(index, className) {
                  if( $this.hasClass(className) ) {
                      func.call( $this, className );
                      $this.trigger('classRemoved', className);
                  }
              });
              prevClasses != this.getAttribute('class') && $this.trigger('classChanged');
          });
          return this;
      }
  })($.fn.removeClass);
  

With these replacement functions you can then handle any class changed via classChanged or specific classes being added or removed by checking the argument to the callback function:

$(document).on('classAdded', '#myElement', function(event, className) {
    if(className == "something") { /* do something */ }
});

I note you suggested this formula

=IF(ISNUMBER(FIND("RuhrP";F9));LOOKUP(A9;Ruhrpumpen!A$5:A$100;Ruhrpumpen!I$5:I$100);"")

.....but LOOKUP isn't appropriate here because I assume you want an exact match (LOOKUP won't guarantee that and also data in lookup range has to be sorted), so VLOOKUP or INDEX/MATCH would be better....and you can also use IFERROR to avoid the IF function, i.e

=IFERROR(VLOOKUP(A9;Ruhrpumpen!A$5:Z$100;9;0);"")

Note: VLOOKUP always looks up the lookup value (A9) in the first column of the "table array" and returns a value from the nth column of the "table array" where n is defined by col_index_num, in this case 9

INDEX/MATCH is sometimes more flexible because you can explicitly define the lookup column and the return column (and return column can be to the left of the lookup column which can't be the case in VLOOKUP), so that would look like this:

=IFERROR(INDEX(Ruhrpumpen!I$5:I$100;MATCH(A9;Ruhrpumpen!A$5:A$100;0));"")

INDEX/MATCH also allows you to more easily return multiple values from different columns, e.g. by using $ signs in front of A9 and the lookup range Ruhrpumpen!A$5:A$100, i.e.

=IFERROR(INDEX(Ruhrpumpen!I$5:I$100;MATCH($A9;Ruhrpumpen!$A$5:$A$100;0));"")

this version can be dragged across to get successive values from column I, column J, column K etc.....

The best solution is toString (as stated above):

function getRealObjectType(obj: {}): string {
    return Object.prototype.toString.call(obj).match(/\[\w+ (\w+)\]/)[1].toLowerCase();
}

FAIR WARNING: toString considers NaN a number so you must manually safeguard later with Number.isNaN(value).

The other solution suggested, using Object.getPrototypeOf fails with null and undefined

It's Simple in Swift . just put this color in your background view color and it will work .

let dimAlphaRedColor =  UIColor.redColor().colorWithAlphaComponent(0.7)
yourView.backGroundColor =  dimAlphaRedColor

This is not a bug in either implementation. There is no requirement to escape U+00B0. To quote the RFC:

2.5. Strings

The representation of strings is similar to conventions used in the C family of programming languages. A string begins and ends with quotation marks. All Unicode characters may be placed within the quotation marks except for the characters that must be escaped: quotation mark, reverse solidus, and the control characters (U+0000 through U+001F).

Any character may be escaped.

Escaping everything inflates the size of the data (all code points can be represented in four or fewer bytes in all Unicode transformation formats; whereas encoding them all makes them six or twelve bytes).

It is more likely that you have a text transcoding bug somewhere in your code and escaping everything in the ASCII subset masks the problem. It is a requirement of the JSON spec that all data use a Unicode encoding.

You can always use command "mysqladmin shutdown"

If you're using StringEntity try this, using your choice of character encoding. It handles foreign characters as well.

From my recent experience, JsonReader#setLenient basically makes the parser very tolerant, even to allow malformed JSON data.

But for certain data retrieved from your trusted RESTful API(s), this error might be caused by trailing white spaces. In such cases, simply trim the data would avoid the error:

String trimmed = result1.trim();

Then gson.fromJson(trimmed, T) might work. Surely this only covers a special case, so YMMV.

For a perfectly dynamic solution, this is achievable by combining a cursor and a temp table. With this solution you do not need to know the starting position nor the length, and it is expandable without having to add any OR's to your SQL query.

For this example, let's say you want to select the ID, Details & creation date from a table where a certain list of text is inside 'Details'.

First create a table FilterTable with the search strings in a column called Search.

As the question starter requested:

insert into [DATABASE].dbo.FilterTable
select 'M510' union
select 'M615' union
select 'M515' union 
select 'M612'

Then you can filter your data as following:

DECLARE @DATA NVARCHAR(MAX)

CREATE TABLE #Result (ID uniqueIdentifier, Details nvarchar(MAX), Created datetime)

DECLARE DataCursor CURSOR local forward_only FOR  
SELECT '%' + Search + '%'
FROM [DATABASE].dbo.FilterTable

OPEN DataCursor   
FETCH NEXT FROM DataCursor INTO @DATA   

WHILE @@FETCH_STATUS = 0   
BEGIN   

    insert into #Result
        select ID, Details, Created
        from [DATABASE].dbo.Table (nolock)
        where Details like @DATA

   FETCH NEXT FROM DataCursor INTO @DATA   
END   

CLOSE DataCursor   
DEALLOCATE DataCursor 

select * from #Result
drop table #Result

Hope this helped

I tried to d this for a while and $sqlcommand = 'SELECT * FROM database WHERE search="'.$searchString.'";';
$sth = $db->prepare($sqlcommand); $sth->execute(); $record = $sth->fetch(); if ($sth->fetchColumn() > 0){} just works if there are TWO identical entries, but, if you replace if ($sth->fetchColumn() > 0){} with if ($result){} it works with only one matching record, hope this helps.

see this code what i am used in my application

String data="{'foo':'bar','coolness':2.0, 'altitude':39000, 'pilot':{'firstName':'Buzz','lastName':'Aldrin'}, 'mission':'apollo 11'}";

I retrieved like this

JSONObject json = (JSONObject) JSONSerializer.toJSON(data);        
    double coolness = json.getDouble( "coolness" );
    int altitude = json.getInt( "altitude" );
    JSONObject pilot = json.getJSONObject("pilot");
    String firstName = pilot.getString("firstName");
    String lastName = pilot.getString("lastName");

    System.out.println( "Coolness: " + coolness );
    System.out.println( "Altitude: " + altitude );
    System.out.println( "Pilot: " + lastName );

This one does well its scrolling job. It's very easy to understand, just really few lines of code, well written and totally readable.

iCalendar was based on a vCalendar and Outlook 2007 handles both formats well so it doesn't really matters which one you choose.

I'm not sure if this stands for Outlook 2003. I guess you should give it a try.

Outlook's default calendar format is iCalendar (*.ics)

With quotes around the date:

mysql> CALL insertEvent('2012.01.01 12:12:12');

Alternatively You can use the brew or curl command for installing things, wherever apt-get is mentioned with a URL...

For example,

curl -O http://www.magentocommerce.com/downloads/assets/1.8.1.0/magento-1.8.1.0.tar.gz

dummyElem.focus() where dummyElem is a hidden object (e.g. has negative zIndex)?

And I simply got this error because I used a totally different DocumentRoot directory.

My main DocumentRoot was the default /var/www/html and on the VirtualHost I used /sites/example.com

I have created a link on /var/www/html/example.com (to /sites/example.com). DocumentRoot was set to /var/www/html/example.com

It worked like a charm.

I've figured out what the issue is the namespace is ambigious in the loggerFactory.AddLog4Net(). Here is a brief summary of how I added log4Net to my Asp.Net Core project.

1. Add the nugget package Microsoft.Extensions.Logging.Log4Net.AspNetCore

2. Add the log4net.config file in your root application folder

3. Open the Startup.cs file and change the Configure method to add log4net support with this line loggerFactory.AddLog4Net

First you have to import the package using Microsoft.Extensions.Logging; using the using statement

Here is the entire method, you have to prefix the ILoggerFactory interface with the namespace

 public void Configure(IApplicationBuilder app, IHostingEnvironment env, NorthwindContext context, Microsoft.Extensions.Logging.ILoggerFactory loggerFactory)
        {
            loggerFactory.AddLog4Net();
            ....
        }

String reverse(String s) {
  int legnth = s.length();
  char[] arrayCh = s.toCharArray();
  for(int i=0; i< length/2; i++) {
      char ch = s.charAt(i);
      arrayCh[i] = arrayCh[legnth-1-i];
      arrayCh[legnth-1-i] = ch;
  } 
 return new String(arrayCh);
}

Code Complete recommends m_varname for member variables.

While I've never thought the m_ notation useful, I would give McConnell's opinion weight in building a standard.

The runtime splits the arguments given at the console at each space.

If you call

myApp.exe arg1 arg2 arg3

The Main Method gets an array of

var args = new string[] {"arg1","arg2","arg3"}

Here is one that will accept both phone numbers and phone numbers with extensions.

function phoneNumber(tel) {
var toString = String(tel),
    phoneNumber = toString.replace(/[^0-9]/g, ""),
    countArrayStr = phoneNumber.split(""),
    numberVar = countArrayStr.length,
    closeStr = countArrayStr.join("");
if (numberVar == 10) {
    var phone = closeStr.replace(/(\d{3})(\d{3})(\d{4})/, "$1.$2.$3"); // Change number symbols here for numbers 10 digits in length. Just change the periods to what ever is needed.
} else if (numberVar > 10) {
    var howMany = closeStr.length,
        subtract = (10 - howMany),
        phoneBeginning = closeStr.slice(0, subtract),
        phoneExtention = closeStr.slice(subtract),
        disX = "x", // Change the extension symbol here
        phoneBeginningReplace = phoneBeginning.replace(/(\d{3})(\d{3})(\d{4})/, "$1.$2.$3"), // Change number symbols here for numbers greater than 10 digits in length. Just change the periods and to what ever is needed. 
        array = [phoneBeginningReplace, disX, phoneExtention],
        afterarray = array.splice(1, 0, " "),
        phone = array.join("");

} else {
    var phone = "invalid number US number";
}
return phone;
}

phoneNumber("1234567891"); // Your phone number here

This workaround is dangerous and not recommended:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

It's not a good idea to disable SSL peer verification. Doing so might expose your requests to MITM attackers.

In fact, you just need an up-to-date CA root certificate bundle. Installing an updated one is as easy as:

1. Downloading up-to-date cacert.pem file from cURL website and

2. Setting a path to it in your php.ini file, e.g. on Windows:

   curl.cainfo=c:\php\cacert.pem

That's it!

There is a nice Online Tool for that : http://www.planetb.ca/syntax-highlight-word

Just copy the generated code and paste it in your word editing software. So far I've tried it on MS Word and WPS Writer, works really well. Doesn't play nice with Firefox but works just fine on Chrome (and IE too, but who wants to use that).

One of the main benefits is that, unlike the Code Format Add-In for Word, it does NOT mess with your code, and respects various languages syntax. I tried many other options offered in other answer but I found this one to be the most efficient (quick and really effective).

There is also another onlinz tool quoted in another answer (markup.su) but I find the planetB output more elegant (although less versatile).

You can try a blank phrase:

document.add(new Phrase("\n"));

However, if protecting the password is important, you should really be using something like SHA256 (MD5 is not cryptographically secure iirc). Even more, you might want to consider using TLS and getting a cert so you can use https.

you can do it using aws cli : https://aws.amazon.com/cli/ and some unix command.

this aws cli commands should work:

aws s3 rm s3://<your_bucket_name> --exclude "*" --include "<your_regex>" 

if you want to include sub-folders you should add the flag --recursive

or with unix commands:

aws s3 ls s3://<your_bucket_name>/ | awk '{print $4}' | xargs -I%  <your_os_shell>   -c 'aws s3 rm s3:// <your_bucket_name>  /% $1'

explanation:

1. list all files on the bucket --pipe-->
2. get the 4th parameter(its the file name) --pipe--> // you can replace it with linux command to match your pattern
3. run delete script with aws cli

You can also put the exclamation mark inside the brackets:

if [[ ! $PATH =~ $temp ]]

but you should anchor your pattern to reduce false positives:

temp=/mnt/silo/bin
pattern="(^|:)${temp}(:|$)"
if [[ ! "${PATH}" =~ ${pattern} ]]

which looks for a match at the beginning or end with a colon before or after it (or both). I recommend using lowercase or mixed case variable names as a habit to reduce the chance of name collisions with shell variables.

You can also add the toolbar in Visual Studio to have the buttons available.

I had a similar problem recently and found out, that client_max_body_size 0; can solve such an issue. This will set client_max_body_size to no limit. But the best practice is to improve your code, so there is no need to increase this limit.

Answer in 2019:

Only use WOFF2, or if you need legacy support, WOFF. Do not use any other format

(svg and eot are dead formats, ttf and otf are full system fonts, and should not be used for web purposes)

Original answer from 2012:

In short, font-face is very old, but only recently has been supported by more than IE.

• eot is needed for Internet Explorers that are older than IE9 - they invented the spec, but eot was a proprietary solution.

• ttf and otf are normal old fonts, so some people got annoyed that this meant anyone could download expensive-to-license fonts for free.

• Time passes, SVG 1.1 adds a "fonts" chapter that explains how to model a font purely using SVG markup, and people start to use it. More time passes and it turns out that they are absolutely terrible compared to just a normal font format, and SVG 2 wisely removes the entire chapter again.

• Then, woff gets invented by people with quite a bit of domain knowledge, which makes it possible to host fonts in a way that throws away bits that are critically important for system installation, but irrelevant for the web (making people worried about piracy happy) and allows for internal compression to better suit the needs of the web (making users and hosts happy). This becomes the preferred format.

• 2019 edit A few years later, woff2 gets drafted and accepted, which improves the compression, leading to even smaller files, along with the ability to load a single font "in parts" so that a font that supports 20 scripts can be stored as "chunks" on disk instead, with browsers automatically able to load the font "in parts" as needed, rather than needing to transfer the entire font up front, further improving the typesetting experience.

If you don't want to support IE 8 and lower, and iOS 4 and lower, and android 4.3 or earlier, then you can just use WOFF (and WOFF2, a more highly compressed WOFF, for the newest browsers that support it.)

@font-face {
  font-family: 'MyWebFont';
  src:  url('myfont.woff2') format('woff2'),
        url('myfont.woff') format('woff');
}

Support for woff can be checked at http://caniuse.com/woff
Support for woff2 can be checked at http://caniuse.com/woff2

this works for me:

cmake -D DBUILD_SHARED_LIBS=ON DBUILD_STATIC_LIBS=ON DBUILD_TESTS=ON ..
