You can try these below views.

SELECT * FROM USER_SYS_PRIVS; 
SELECT * FROM USER_TAB_PRIVS;
SELECT * FROM USER_ROLE_PRIVS;

DBAs and other power users can find the privileges granted to other users with the DBA_ versions of these same views. They are covered in the documentation .

Those views only show the privileges granted directly to the user. Finding all the privileges, including those granted indirectly through roles, requires more complicated recursive SQL statements:

select * from dba_role_privs connect by prior granted_role = grantee start with grantee = '&USER' order by 1,2,3;
select * from dba_sys_privs  where grantee = '&USER' or grantee in (select granted_role from dba_role_privs connect by prior granted_role = grantee start with grantee = '&USER') order by 1,2,3;
select * from dba_tab_privs  where grantee = '&USER' or grantee in (select granted_role from dba_role_privs connect by prior granted_role = grantee start with grantee = '&USER') order by 1,2,3,4;

Use the following command (notice the "d"): mysqld --skip-grant-tables

To answer your question, on Windows, the my.cnf file may be called my.ini. MySQL looks for it in the following locations (in this order):

• %PROGRAMDATA%\MySQL\MySQL Server 5.7\my.ini, %PROGRAMDATA%\MySQL\MySQL Server 5.7\my.cnf
• %WINDIR%\my.ini, %WINDIR%\my.cnf
• C:\my.ini, C:\my.cnf
• INSTALLDIR\my.ini, INSTALLDIR\my.cnf

See also http://dev.mysql.com/doc/refman/5.7/en/option-files.html

Then you can edit the config file and add an entry like this:

[mysqld]
skip-grant-tables

Then restart the MySQL Service and you can log in and do what you need to do. Of course you want to disable that entry in the config file as soon as possible!

See also http://dev.mysql.com/doc/refman/5.7/en/resetting-permissions.html

In addition mysql passwords when not using the IDENTIFIED BY clause, may be blank values, if non-blank, they may be encrypted. But yes USAGE is used to modify an account by granting simple resource limiters such as MAX_QUERIES_PER_HOUR, again this can be specified by also using the WITH clause, in conjuction with GRANT USAGE(no privileges added) or GRANT ALL, you can also specify GRANT USAGE at the global level, database level, table level,etc....

for ORA-01031: insufficient privileges. Some of the more common causes are:

1. You tried to change an Oracle username or password without having the appropriate privileges.
2. You tried to perform an UPDATE to a table, but you only have SELECT access to the table.
3. You tried to start up an Oracle database using CONNECT INTERNAL.
4. You tried to install an Oracle database without having the appropriate privileges to the operating-system.

The option(s) to resolve this Oracle error are:

1. You can have the Oracle DBA grant you the appropriate privileges that you are missing.
2. You can have the Oracle DBA execute the operation for you.
3. If you are having trouble starting up Oracle, you may need to add the Oracle user to the dba group.

For ORA-00942: table or view does not exist. You tried to execute a SQL statement that references a table or view that either does not exist, that you do not have access to, or that belongs to another schema and you didn't reference the table by the schema name.

If this error occurred because the table or view does not exist, you will need to create the table or view.

You can check to see if the table exists in Oracle by executing the following SQL statement:

select *
from all_objects
where object_type in ('TABLE','VIEW')
and object_name = 'OBJECT_NAME';

For example, if you are looking for a suppliers table, you would execute:

select *
from all_objects
where object_type in ('TABLE','VIEW')
and object_name = 'SUPPLIERS';

OPTION #2

If this error occurred because you do not have access to the table or view, you will need to have the owner of the table/view, or a DBA grant you the appropriate privileges to this object.

OPTION #3

If this error occurred because the table/view belongs to another schema and you didn't reference the table by the schema name, you will need to rewrite your SQL to include the schema name.

For example, you may have executed the following SQL statement:

select *
from suppliers;

But the suppliers table is not owned by you, but rather, it is owned by a schema called app, you could fix your SQL as follows:

select *
from app.suppliers;

If you do not know what schema the suppliers table/view belongs to, you can execute the following SQL to find out:

select owner
from all_objects
where object_type in ('TABLE','VIEW')
and object_name = 'SUPPLIERS';

This will return the schema name who owns the suppliers table.

Find the file "config.inc.php" under your phpMyAdmin directory and edit the following lines:

$cfg['Servers'][$i]['auth_type'] = 'config'; // config, http, cookie

$cfg['Servers'][$i]['user'] = 'root'; // MySQL user

$cfg['Servers'][$i]['password'] = 'TYPE_YOUR_PASSWORD_HERE'; // MySQL password

Note that the password used in the 'password' field must be the same for the MySQL root password. Also, you should check if root login is allowed in this line:

$cfg['Servers'][$i]['AllowRoot']     = TRUE;        // true = allow root login

This way you have your root password set.

Mark Russinovich wrote a terrific tool called AccessChk that lets you get this information from the command line. No installation is necessary.

http://technet.microsoft.com/en-us/sysinternals/bb664922.aspx

For example:

accesschk.exe /accepteula -q -a SeServiceLogonRight

Returns this for me:

IIS APPPOOL\DefaultAppPool
IIS APPPOOL\Classic .NET AppPool
NT SERVICE\ALL SERVICES

By contrast, whoami /priv and whoami /all were missing some entries for me, like SeServiceLogonRight.

You cannot insert data because you have a quota of 0 on the tablespace. To fix this, run

ALTER USER <user> quota unlimited on <tablespace name>;

or

ALTER USER <user> quota 100M on <tablespace name>;

as a DBA user (depending on how much space you need / want to grant).

If you facing grant permission access denied problem, you can try mysql to fix the problem:

grant all privileges on . to root@'localhost' identified by 'Your password';

grant all privileges on . to root@'IP ADDRESS' identified by 'Your password?';

your can try this on any mysql user, its working.

Use below command to login mysql with iP address.

mysql -h 10.0.0.23 -u root -p

You should use this example with AUTHID CURRENT_USER :

CREATE OR REPLACE PROCEDURE Create_sequence_for_tab (VAR_TAB_NAME IN VARCHAR2)
   AUTHID CURRENT_USER
IS
   SEQ_NAME       VARCHAR2 (100);
   FINAL_QUERY    VARCHAR2 (100);
   COUNT_NUMBER   NUMBER := 0;
   cur_id         NUMBER;
BEGIN
   SEQ_NAME := 'SEQ_' || VAR_TAB_NAME;

   SELECT COUNT (*)
     INTO COUNT_NUMBER
     FROM USER_SEQUENCES
    WHERE SEQUENCE_NAME = SEQ_NAME;

   DBMS_OUTPUT.PUT_LINE (SEQ_NAME || '>' || COUNT_NUMBER);

   IF COUNT_NUMBER = 0
   THEN
      --DBMS_OUTPUT.PUT_LINE('DROP SEQUENCE ' || SEQ_NAME);
      -- EXECUTE IMMEDIATE 'DROP SEQUENCE ' || SEQ_NAME;
      -- ELSE
      SELECT 'CREATE SEQUENCE COMPTABILITE.' || SEQ_NAME || ' START WITH ' || ROUND (DBMS_RANDOM.VALUE (100000000000, 999999999999), 0) || ' INCREMENT BY 1'
        INTO FINAL_QUERY
        FROM DUAL;

      DBMS_OUTPUT.PUT_LINE (FINAL_QUERY);
      cur_id := DBMS_SQL.OPEN_CURSOR;
      DBMS_SQL.parse (cur_id, FINAL_QUERY, DBMS_SQL.v7);
      DBMS_SQL.CLOSE_CURSOR (cur_id);
   -- EXECUTE IMMEDIATE FINAL_QUERY;

   END IF;

   COMMIT;
END;

To see the internal representation size in bytes you can use:

REGEXP_SUBSTR(DUMP(your_column_name), 'Len=(\d+)\:', 1, 1, 'c', 1 ) 

Windows 7 requires that you intentionally ask for certain privileges so that a malicious program can't do bad things to you. If the free calculator you downloaded needed to be run as an administrator, you would know something is up. There are OS commands to elevate the privilege of your application (which will request confirmation from the user).

A good description can be found at:

http://msdn.microsoft.com/en-us/magazine/cc163486.aspx#S4

Because the SCHEDULER_ADMIN role is a powerful role allowing a grantee to execute code as any user, you should consider granting individual Scheduler system privileges instead. Object and system privileges are granted using regular SQL grant syntax. An example is if the database administrator issues the following statement:

GRANT CREATE JOB TO scott;

After this statement is executed, scott can create jobs, schedules, or programs in his schema.

copied from http://docs.oracle.com/cd/B19306_01/server.102/b14231/schedadmin.htm#i1006239

All commands must be executed while connected to the right database in the right database cluster. Make sure of it.

The user needs access to the database, obviously:

GRANT CONNECT ON DATABASE my_db TO my_user;

And (at least) the USAGE privilege on the schema:

GRANT USAGE ON SCHEMA public TO my_user;

Or grant USAGE on all custom schemas:

DO
$$
BEGIN
   -- RAISE NOTICE '%', (  -- use instead of EXECUTE to see generated commands
   EXECUTE (
   SELECT string_agg(format('GRANT USAGE ON SCHEMA %I TO my_user', nspname), '; ')
   FROM   pg_namespace
   WHERE  nspname <> 'information_schema' -- exclude information schema and ...
   AND    nspname NOT LIKE 'pg\_%'        -- ... system schemas
   );
END
$$;

Then, all permissions for all tables (requires Postgres 9.0 or later).
And don't forget sequences (if any):

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO my_user;
GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public TO my_user;

For older versions you could use the "Grant Wizard" of pgAdmin III (the default GUI).

There are some other objects, the manual for GRANT has the complete list as of Postgres 12:

privileges on a database object (table, column, view, foreign table, sequence, database, foreign-data wrapper, foreign server, function, procedure, procedural language, schema, or tablespace)

But the rest is rarely needed. More details:

• How to manage DEFAULT PRIVILEGES for USERs on a DATABASE vs SCHEMA?
• Grant privileges for a particular database in PostgreSQL
• How to grant all privileges on views to arbitrary user

Consider upgrading to a current version.

For me, I found the suggestion in the following thread helped:

Stop "developer tools access needs to take control of another process for debugging to continue" alert

It suggested running the following command in the Terminal application:

sudo /usr/sbin/DevToolsSecurity --enable

1st and important step is connect to your db:

psql -d yourDBName

2 step, grant privileges

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO userName;

GRANT ALL ON *.* TO 'user'@'localhost' with GRANT OPTION;

Just log in from root using the respective password if any and simply run the above command to whatever the user is.

For example:

GRANT ALL ON *.* TO 'root'@'%' with GRANT OPTION;

Use this to list Grantee too and remove (PG_monitor and Public) for Postgres PaaS Azure.

SELECT grantee,table_catalog, table_schema, table_name, privilege_type
FROM   information_schema.table_privileges 
WHERE  grantee not in ('pg_monitor','PUBLIC');

My answer is similar to this one on ServerFault.com.

To Be Conservative

If you want to be more conservative than granting "all privileges", you might want to try something more like these.

GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO some_user_;
GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA public TO some_user_;

The use of public there refers to the name of the default schema created for every new database/catalog. Replace with your own name if you created a schema.

Access to the Schema

To access a schema at all, for any action, the user must be granted "usage" rights. Before a user can select, insert, update, or delete, a user must first be granted "usage" to a schema.

You will not notice this requirement when first using Postgres. By default every database has a first schema named public. And every user by default has been automatically been granted "usage" rights to that particular schema. When adding additional schema, then you must explicitly grant usage rights.

GRANT USAGE ON SCHEMA some_schema_ TO some_user_ ;

Excerpt from the Postgres doc:

For schemas, allows access to objects contained in the specified schema (assuming that the objects' own privilege requirements are also met). Essentially this allows the grantee to "look up" objects within the schema. Without this permission, it is still possible to see the object names, e.g. by querying the system tables. Also, after revoking this permission, existing backends might have statements that have previously performed this lookup, so this is not a completely secure way to prevent object access.

For more discussion see the Question, What GRANT USAGE ON SCHEMA exactly do?. Pay special attention to the Answer by Postgres expert Craig Ringer.

Existing Objects Versus Future

These commands only affect existing objects. Tables and such you create in the future get default privileges until you re-execute those lines above. See the other answer by Erwin Brandstetter to change the defaults thereby affecting future objects.

As a side note, the reason revoke usage on *.* from 'phpmyadmin'@'localhost'; does not work is quite simple : There is no grant called USAGE.

The actual named grants are in the MySQL Documentation

The grant USAGE is a logical grant. How? 'phpmyadmin'@'localhost' has an entry in mysql.user where user='phpmyadmin' and host='localhost'. Any row in mysql.user semantically means USAGE. Running DROP USER 'phpmyadmin'@'localhost'; should work just fine. Under the hood, it's really doing this:

DELETE FROM mysql.user WHERE user='phpmyadmin' and host='localhost';
DELETE FROM mysql.db   WHERE user='phpmyadmin' and host='localhost';
FLUSH PRIVILEGES;

Therefore, the removal of a row from mysql.user constitutes running REVOKE USAGE, even though REVOKE USAGE cannot literally be executed.

I have built semi-long shell scripts (300-500 lines) and Python code which does similar functionality. When many external commands are being executed, I find the shell is easier to use. Perl is also a good option when there is lots of text manipulation.

Modify MainActivity like this,

@Override
protected String getMainComponentName() {
    return "Bananas"; // here
}

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

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

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

Try MySQL Workbench, formerly DBDesigner 4:

http://dev.mysql.com/workbench/

This has a "Reverse Engineer Database" mode:

Database -> Reverse Engineer

Relative:

1. An element with position: relative; is positioned relative to its normal position.

2. If you add no positioning attributes (top, left, bottom or right) on a relative element it will have no effect on it's positioning at all. It will behave exactly as a position: static element.

3. But if you do add some other positioning attribute, say, top: 10px;, it will shift its position 10 pixels down from where it would normally be.

4. An element with this type of positioning gets affected by other elements and it itself also affects others.

Absolute:

1. An element with position: absolute; allows you to place any element exactly where you want it to be. You use the positioning attributes top, left, bottom. and right to set the location.

2. It is placed relative to the nearest non-static ancestor. If there is no such container, it is placed relative to the page itself.

3. It gets removed from the normal flow of elements on the page.

4. An element with this type of positioning is not affected by other elements and also it doesn't affect flow of other elements.

See this self-explanatory example for better clarity. https://codepen.io/nyctophiliac/pen/BJMqjX

$(document).ready(function() {
    $(document).on("click", ".question", function(e) {
       var checked = $(this).find("input:checkbox").is(":checked");
       if (checked) {
           $('.answer').show(300);
       } else {
           $('.answer').hide(300);
       }
    });
});

(I presume you are aware that using UDP(User Datagram Protocol) does not guarantee delivery, checks for duplicates and congestion control and will just answer your question).

In your server this line:

var data = udpServer.Receive(ref groupEP);

re-assigns groupEP from what you had to a the address you receive something on.

This line:

udpServer.Send(new byte[] { 1 }, 1); 

Will not work since you have not specified who to send the data to. (It works on your client because you called connect which means send will always be sent to the end point you connected to, of course we don't want that on the server as we could have many clients). I would:

UdpClient udpServer = new UdpClient(UDP_LISTEN_PORT);

while (true)
{
    var remoteEP = new IPEndPoint(IPAddress.Any, 11000);
    var data = udpServer.Receive(ref remoteEP);
    udpServer.Send(new byte[] { 1 }, 1, remoteEP); // if data is received reply letting the client know that we got his data          
}

Also if you have server and client on the same machine you should have them on different ports.

A pointer pointing to a memory location that has been deleted (or freed) is called dangling pointer. There are three different ways where Pointer acts as dangling pointer.

1. De-allocation of memory
2. Function Call
3. Variable goes out of scope

—— from https://www.geeksforgeeks.org/dangling-void-null-wild-pointers/

It looks suspicious because there is no apparent function that is being returned from!

It is an anonymous function that has been attached to the click event of the object.

why are you doing this, Steve?

Why on earth are you doi.....Ah nevermind, as you've mentioned, it really is widely adopted bad practice :)

If you only want to read the first 999,999 (non-header) rows:

read_csv(..., nrows=999999)

If you only want to read rows 1,000,000 ... 1,999,999

read_csv(..., skiprows=1000000, nrows=999999)

nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*

skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file

and for large files, you'll probably also want to use chunksize:

chunksize : int, default None Return TextFileReader object for iteration

pandas.io.parsers.read_csv documentation

Try calling it like: obj.some_function( '1', 2, '3', g="foo", h="bar" ). After the required positional arguments, you can specify specific optional arguments by name.

You can do a function like this:

def getLastItem(dictionary):
    last_keyval = dictionary.popitem()
    dictionary.update({last_keyval[0]:last_keyval[1]})
    return {last_keyval[0]:last_keyval[1]}

This not change the original dictionary! This happen because the popitem() function returns a tuple and we can utilize this for us favor!!

Underscore. Not space.

$_SERVER['HTTP_REFERER']

I don't try changing sequence via setval. But using ALTER I was issued how to write sequence name properly. And this only work for me:

1. Check required sequence name using SELECT * FROM information_schema.sequences;

2. ALTER SEQUENCE public."table_name_Id_seq" restart {number};

   In my case it was ALTER SEQUENCE public."Services_Id_seq" restart 8;

Also there is a page on wiki.postgresql.org where describes a way to generate sql script to fix sequences in all database tables at once. Below the text from link:

Save this to a file, say 'reset.sql'

SELECT 'SELECT SETVAL(' ||
       quote_literal(quote_ident(PGT.schemaname) || '.' || quote_ident(S.relname)) ||
       ', COALESCE(MAX(' ||quote_ident(C.attname)|| '), 1) ) FROM ' ||
       quote_ident(PGT.schemaname)|| '.'||quote_ident(T.relname)|| ';'
FROM pg_class AS S,
     pg_depend AS D,
     pg_class AS T,
     pg_attribute AS C,
     pg_tables AS PGT
WHERE S.relkind = 'S'
    AND S.oid = D.objid
    AND D.refobjid = T.oid
    AND D.refobjid = C.attrelid
    AND D.refobjsubid = C.attnum
    AND T.relname = PGT.tablename
ORDER BY S.relname;

Run the file and save its output in a way that doesn't include the usual headers, then run that output. Example:

psql -Atq -f reset.sql -o temp
psql -f temp
rm temp

And the output will be a set of sql commands which look exactly like this:

SELECT SETVAL('public."SocialMentionEvents_Id_seq"', COALESCE(MAX("Id"), 1) ) FROM public."SocialMentionEvents";
SELECT SETVAL('public."Users_Id_seq"', COALESCE(MAX("Id"), 1) ) FROM public."Users";

It's because you haven't declared outchar before you use it. That means that the compiler will assume it's a function returning an int and taking an undefined number of undefined arguments.

You need to add a prototype pf the function before you use it:

void outchar(char);  /* Prototype (declaration) of a function to be called */  int main(void) {     ... }  void outchar(char ch) {     ... } 

Note the declaration of the main function differs from your code as well. It's actually a part of the official C specification, it must return an int and must take either a void argument or an int and a char** argument.

I don't think it will make a significant difference in compile time but #pragma once is very well supported across compilers but not actually part of the standard. The preprocessor may be a little faster with it as it is more simple to understand your exact intent.

#pragma once is less prone to making mistakes and it is less code to type.

To speed up compile time more just forward declare instead of including in .h files when you can.

I prefer to use #pragma once.

See this wikipedia article about the possibility of using both.

import datetime from datetime

now = datetime.now()

print "%0.2d:%0.2d:%0.2d" % (now.hour, now.minute, now.second)

You can do the same with day & month etc.

As documentation says:

Raised when the part of a "multipart/form-data" request identified by its name cannot be found.

This may be because the request is not a multipart/form-data either because the part is not present in the request, or because the web application is not configured correctly for processing multipart requests -- e.g. no MultipartResolver.

…just because this method hasn't been mentioned so far - open the console and type:

If you really need to do it in separate transaction you need to use REQUIRES_NEW and live with the performance overhead. Watch out for dead locks.

I'd rather do it the other way:

• Validate data on Java side.
• Run everyting in one transaction.
• If anything goes wrong on DB side -> it's a major error of DB or validation design. Rollback everything and throw critical top level error.
• Write good unit tests.

See my answer to "How to escape characters in MySQL"

Whatever library you are using to talk to MySQL will have an escaping function built in, e.g. in PHP you could use mysqli_real_escape_string or PDO::quote

1. Just use https://romannurik.github.io/AndroidAssetStudio/index.html. It can make a set of icons from an image, later you can download a zip-file.
2. Or download a Windows application at https://github.com/redwarp/9-Patch-Resizer/releases (doesn't need to install) and open an icon.
3. Also you can use a plugin Android Drawable Importer, see answers above. Because it is abandoned, install forks. See Why does Android Drawable Importer ignore selection in AS 3.5 onwards or https://github.com/Vincent-Loi/android-drawable-importer-intellij-plugin.
4. https://appicon.co/#image-sets.

If you have a Uri that conforms to the DocumentContract then you probably don't want to use File. If you are on kotlin, use DocumentFile to do stuff you would in the old World use File for, and use ContentResolver to get streams.

Everything else is pretty much guaranteed to break.

You can use Linq in case you are using .NET 3.5 or later:

 test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();

If you can't use Linq then you can do it like this:

var temp = new List<string>();
foreach (var s in test)
{
    if (!string.IsNullOrEmpty(s))
        temp.Add(s);
}
test = temp.ToArray();

Under the Links Tab ==> Edit the URL Item ==> Under the URL (Type the Web address)- format the value as follows:

Example: if the URL = http://www.abc.com ==> then suffix the value with ==>

• #openinnewwindow/,'" target="http://www.abc.com'

SO, the final value should read as ==> http://www.abc.com#openinnewwindow/,'" target="http://www.abc.com'

DONE ==> this will open the URL in New Window

My guess is that the system-status element is declared after the variable declaration is run. Thus, at the time the variable is declared, it is actually being set to null?

You should declare it only, then assign its value from an onLoad handler instead, because then you will be sure that it has properly initialized (loaded) the element in question.

You could also try putting the script at the bottom of the page (or at least somewhere after the system-status element is declared) but it's not guaranteed to always work.

Here is the class LocationFinder to find the GPS location. This class will call MyLocation, which will do the business.

This is a FAQ:

//somexpression[$N]

means "Find every node selected by //somexpression that is the $Nth child of its parent".

What you want is:

(//input[@id="search_query"])[2]

Remember: The [] operator has higher precedence (priority) than the // abbreviation.

In case you update the image multiple times and it gets CACHED and does not update, add a random string at the end:

// update image in dom
$('#target').attr('src', 'https://example.com/img.jpg?rand=' + Math.random());

Watch out for possible unintended literals in your argument

for example you can have a space within your argument, rendering it to a string / literal:

float(' 0.33')

After making sure the unintended space did not make it into the argument, I was left with:

float(0.33) 

Like this it works like a charm.

Take away is: Pay Attention for unintended literals (e.g. spaces that you didn't see) within your input.

I like lambda :)

 private void ClearTextBoxes()
 {
     Action<Control.ControlCollection> func = null;

     func = (controls) =>
         {
             foreach (Control control in controls)
                 if (control is TextBox)
                     (control as TextBox).Clear();
                 else
                     func(control.Controls);
         };

     func(Controls);
 }

Good luck!

You need to escape the ampersand:

<div class="test">&amp;times</div>

&times means a multiplication sign. (Technically it should be × but lenient browsers let you omit the ;.)

mysqladmin is not a SQL statement. It's a little helper utility program you'll find on your MySQL server... and "flush-hosts" is one of the things it can do. ("status" and "shutdown" are a couple of other things that come to mind).

You type that command from a shell prompt.

Alternately, from your query browser (such as phpMyAdmin), the SQL statement you're looking for is simply this:

FLUSH HOSTS;

http://dev.mysql.com/doc/refman/5.6/en/flush.html

http://dev.mysql.com/doc/refman/5.6/en/mysqladmin.html

Current memory usage of the current process on Linux, for Python 2, Python 3, and pypy, without any imports:

def getCurrentMemoryUsage():
    ''' Memory usage in kB '''

    with open('/proc/self/status') as f:
        memusage = f.read().split('VmRSS:')[1].split('\n')[0][:-3]

    return int(memusage.strip())

It reads the status file of the current process, takes everything after VmRSS:, then takes everything before the first newline (isolating the value of VmRSS), and finally cuts off the last 3 bytes which are a space and the unit (kB).
To return, it strips any whitespace and returns it as a number.

Tested on Linux 4.4 and 4.9, but even an early Linux version should work: looking in man proc and searching for the info on the /proc/$PID/status file, it mentions minimum versions for some fields (like Linux 2.6.10 for "VmPTE"), but the "VmRSS" field (which I use here) has no such mention. Therefore I assume it has been in there since an early version.

Use a list instead and replace your foreach loop with a for loop:

@model IList<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()

    @for (var i = 0; i < Model.Count; i++) 
    {
        <tr>
            <td>
                @Html.HiddenFor(x => x[i].IP)           
                @Html.CheckBoxFor(x => x[i].Checked)
            </td>
            <td>
                @Html.DisplayFor(x => x[i].IP)
            </td>
        </tr>
    }
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

Alternatively you could use an editor template:

@model IEnumerable<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()
    @Html.EditorForModel()   
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

and then define the template ~/Views/Shared/EditorTemplates/BlockedIPViewModel.cshtml which will automatically be rendered for each element of the collection:

@model BlockedIPViewModel
<tr>
    <td>
        @Html.HiddenFor(x => x.IP)
        @Html.CheckBoxFor(x => x.Checked)
    </td>
    <td>
        @Html.DisplayFor(x => x.IP)
    </td>
</tr>

The reason you were getting null in your controller is because you didn't respect the naming convention for your input fields that the default model binder expects to successfully bind to a list. I invite you to read the following article.

Once you have read it, look at the generated HTML (and more specifically the names of the input fields) with my example and yours. Then compare and you will understand why yours doesn't work.

If you want to gain access to the whole the error body, do it as shown below:

 async function login(reqBody) {
  try {
    let res = await Axios({
      method: 'post',
      url: 'https://myApi.com/path/to/endpoint',
      data: reqBody
    });

    let data = res.data;
    return data;
  } catch (error) {
    console.log(error.response); // this is the main part. Use the response property from the error object

    return error.response;
  }

}

And then there is the somewhat older recode program.

According to this code golfing solution by Gaffi, the following works:

a = Split(StrConv(s, 64), Chr(0))

sudo is a command for Linux so it cant be used in windows so you will get that error

Try installing the 32 bit version of Java 6. This works for version Install4J 4.0.5. Should fire right up, or allow you to re-run the installer.

Any newer version or the 64-bit version of 6 will fail, complaining that the java.exe is damaged.

In windows just open the explorer navigate to your SLN folder click into search field and type kind:=folder;obj --> for obj folders use CTRL+A and delete 'em - same for bin Done

No need for any tool or extra software ;)

$location won't help you with external URLs, use the $window service instead:

$window.location.href = 'http://www.google.com';

Note that you could use the window object, but it is bad practice since $window is easily mockable whereas window is not.

Try sdiff (man sdiff)

sdiff -s file1 file2

to creating some thing that is running like service you can use this thing :

The first thing that you must do is installing the Cement framework: Cement frame work is a CLI frame work that you can deploy your application on it.

command line interface of the app :

interface.py

 from cement.core.foundation import CementApp
 from cement.core.controller import CementBaseController, expose
 from YourApp import yourApp

 class Meta:
    label = 'base'
    description = "your application description"
    arguments = [
        (['-r' , '--run'],
          dict(action='store_true', help='Run your application')),
        (['-v', '--version'],
          dict(action='version', version="Your app version")),
        ]
        (['-s', '--stop'],
          dict(action='store_true', help="Stop your application")),
        ]

    @expose(hide=True)
    def default(self):
        if self.app.pargs.run:
            #Start to running the your app from there !
            YourApp.yourApp()
        if self.app.pargs.stop:
            #Stop your application
            YourApp.yourApp.stop()

 class App(CementApp):
       class Meta:
       label = 'Uptime'
       base_controller = 'base'
       handlers = [MyBaseController]

 with App() as app:
       app.run()

YourApp.py class:

 import threading

 class yourApp:
     def __init__:
        self.loger = log_exception.exception_loger()
        thread = threading.Thread(target=self.start, args=())
        thread.daemon = True
        thread.start()

     def start(self):
        #Do every thing you want
        pass
     def stop(self):
        #Do some things to stop your application

Keep in mind that your app must run on a thread to be daemon

To run the app just do this in command line

python interface.py --help

In swift 4 you can write it smarter:

let d = [ 1 : "hello", 2 : "bye", -1 : "foo" ]
d = [Int : String](uniqueKeysWithValues: d.sorted{ $0.key < $1.key })

There are two things to fix about this. First set up the stored procedure to store the value in the output ( not return ) parameter.

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go

ALTER PROCEDURE [dbo].[Validate]
@a varchar(50),
@b varchar(50) output

AS

SET @b = 
(SELECT Password
FROM dbo.tblUser
WHERE Login = @a)

RETURN
GO

This will but the password into @b and you will get it as a return parameter. Then to get it in your C# do this:

SqlConnection SqlConn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["MyLocalSQLServer"].ConnectionString.ToString());
    System.Data.SqlClient.SqlCommand sqlcomm = new System.Data.SqlClient.SqlCommand("Validate", SqlConn);

    string returnValue = string.Empty;

    try
    {
        SqlConn.Open();
        sqlcomm.CommandType = CommandType.StoredProcedure;

        SqlParameter param = new SqlParameter("@a", SqlDbType.VarChar, 50);
        param.Direction = ParameterDirection.Input;
        param.Value = Username;
        sqlcomm.Parameters.Add(param);



        SqlParameter retval = new SqlParameter("@b", SqlDbType.VarChar, 50);
        retval.Direction = ParameterDirection.ReturnValue;
        sqlcomm.Parameters.Add(retval);

        sqlcomm.ExecuteNonQuery();
        SqlConn.Close();

        string retunvalue = retval.Value.ToString();
     }

The vertical-align CSS property specifies the vertical alignment of an inline, inline-block or table-cell element.

Also note that some plugins (remote-resources comes to mind) use a really old library that only accepts proxy configuration through MAVEN_OPTS;

-Dhttp.proxyHost=<host> -Dhttp.proxyPort=<port> -Dhttps.proxyHost=<host> -Dhttps.proxyPort=<port>

You might be stuck on auth for this one.

This is due to the fact that cv2 uses the type "uint8" from numpy. Therefore, you should define the type when creating the array.

Something like the following:

import numpy
import cv2

b = numpy.zeros([5,5,3], dtype=numpy.uint8)
b[:,:,0] = numpy.ones([5,5])*64
b[:,:,1] = numpy.ones([5,5])*128
b[:,:,2] = numpy.ones([5,5])*192

The latest release of Requests will build CookieJars for you from simple dictionaries.

import requests

Enjoy :)

And in 2016.....I do this (which works in all browsers and does not create "illegal" html).

For the drop-down select that is to show/hide different values add that value as a data attribute.

<select id="animal">
    <option value="1" selected="selected">Dog</option>
    <option value="2">Cat</option>
</select>
<select id="name">
    <option value=""></option>
    <option value="1" data-attribute="1">Rover</option>
    <option value="2" selected="selected" data-attribute="1">Lassie</option>
    <option value="3" data-attribute="1">Spot</option>
    <option value="4" data-attribute="2">Tiger</option>
    <option value="5" data-attribute="2">Fluffy</option>
</select>

Then in your jQuery add a change event to the first drop-down select to filter the second drop-down.

$("#animal").change( function() {
    filterSelectOptions($("#name"), "data-attribute", $(this).val());
});

And the magic part is this little jQuery utility.

function filterSelectOptions(selectElement, attributeName, attributeValue) {
    if (selectElement.data("currentFilter") != attributeValue) {
        selectElement.data("currentFilter", attributeValue);
        var originalHTML = selectElement.data("originalHTML");
        if (originalHTML)
            selectElement.html(originalHTML)
        else {
            var clone = selectElement.clone();
            clone.children("option[selected]").removeAttr("selected");
            selectElement.data("originalHTML", clone.html());
        }
        if (attributeValue) {
            selectElement.children("option:not([" + attributeName + "='" + attributeValue + "'],:not([" + attributeName + "]))").remove();
        }
    }
}

This little gem tracks the current filter, if different it restores the original select (all items) and then removes the filtered items. If the filter item is empty we see all items.

All standard implementations of java.util.List already implement java.io.Serializable.

So even though java.util.List itself is not a subtype of java.io.Serializable, it should be safe to cast the list to Serializable, as long as you know it's one of the standard implementations like ArrayList or LinkedList.

If you're not sure, then copy the list first (using something like new ArrayList(myList)), then you know it's serializable.

If you have a collection of objects that you load using stored procedure you can also use LoadFromCollection.

using (ExcelPackage package = new ExcelPackage(file))
{
    ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("test");

    worksheet.Cells["A1"].LoadFromCollection(myColl, true, OfficeOpenXml.Table.TableStyles.Medium1);

    package.Save();
}

Note that for this particular application there's a standard library function, android.text.format.DateUtils.getRelativeTimeSpanString().

If you want to set permissions on all files to a+r, and all directories to a+x, and do that recursively through the complete subdirectory tree, use:

chmod -R a+rX *

The X (that is capital X, not small x!) is ignored for files (unless they are executable for someone already) but is used for directories.

Use the FileSystemObject object, namely, its CreateFolder and CopyFile methods. Basically, this is what your script will look like:

Dim oFSO
Set oFSO = CreateObject("Scripting.FileSystemObject")

' Create a new folder
oFSO.CreateFolder "C:\MyFolder"

' Copy a file into the new folder
' Note that the destination folder path must end with a path separator (\)
oFSO.CopyFile "\\server\folder\file.ext", "C:\MyFolder\"

You may also want to add additional logic, like checking whether the folder you want to create already exists (because CreateFolder raises an error in this case) or specifying whether or not to overwrite the file being copied. So, you can end up with this:

Const strFolder = "C:\MyFolder\", strFile = "\\server\folder\file.ext"
Const Overwrite = True
Dim oFSO

Set oFSO = CreateObject("Scripting.FileSystemObject")

If Not oFSO.FolderExists(strFolder) Then
  oFSO.CreateFolder strFolder
End If

oFSO.CopyFile strFile, strFolder, Overwrite

Yes, \ in Python string literals denotes the start of an escape sequence. In your path you have a valid two-character escape sequence \a, which is collapsed into one character that is ASCII Bell:

>>> '\a'
'\x07'
>>> len('\a')
1
>>> 'C:\meshes\as'
'C:\\meshes\x07s'
>>> print('C:\meshes\as')
C:\meshess

Other common escape sequences include \t (tab), \n (line feed), \r (carriage return):

>>> list('C:\test')
['C', ':', '\t', 'e', 's', 't']
>>> list('C:\nest')
['C', ':', '\n', 'e', 's', 't']
>>> list('C:\rest')
['C', ':', '\r', 'e', 's', 't']

As you can see, in all these examples the backslash and the next character in the literal were grouped together to form a single character in the final string. The full list of Python's escape sequences is here.

There are a variety of ways to deal with that:

1. Python will not process escape sequences in string literals prefixed with r or R:

   >>> r'C:\meshes\as'
   'C:\\meshes\\as'
   >>> print(r'C:\meshes\as')
   C:\meshes\as
   

2. Python on Windows should handle forward slashes, too.

3. You could use os.path.join ...

   >>> import os
   >>> os.path.join('C:', os.sep, 'meshes', 'as')
   'C:\\meshes\\as'
   

4. ... or the newer pathlib module

   >>> from pathlib import Path
   >>> Path('C:', '/', 'meshes', 'as')
   WindowsPath('C:/meshes/as')
   

In C# you can use the following to replace the single quote with a double quote:

 string sample = "St. Mary's";
 string escapedSample = sample.Replace("'", "''");

And the output will be:

"St. Mary''s"

And, if you are working with Sqlite directly; you can work with object instead of string and catch special things like DBNull:

private static string MySqlEscape(Object usString)
{
    if (usString is DBNull)
    {
        return "";
    }
    string sample = Convert.ToString(usString);
    return sample.Replace("'", "''");
}

the easiest way is to simply push to the new branch:

git push -u origin branch/name

Iteration. It creates a state machine "under the covers" that remembers where you were on each additional cycle of the function and picks up from there.

try this

html

<div ng-controller="MyCtrl">
  Hello, {{newDate | date:'MM/dd/yyyy'}}!
</div>

JS

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

function MyCtrl($scope) {
    var collectionDate = '2002-04-26T09:00:00'; 

    $scope.newDate =new Date(collectionDate);
}

Demo

f = open('some_file.txt','r')
line_num = 0
search_phrase = "the dog barked"
for line in f.readlines():
    line_num += 1
    if line.find(search_phrase) >= 0:
        print line_num

EDIT 1.5 years later (after seeing it get another upvote): I'm leaving this as is; but if I was writing today would write something closer to Ash/suzanshakya's solution:

def line_num_for_phrase_in_file(phrase='the dog barked', filename='file.txt')
    with open(filename,'r') as f:
        for (i, line) in enumerate(f):
            if phrase in line:
                return i
    return -1

• Using with to open files is the pythonic idiom -- it ensures the file will be properly closed when the block using the file ends.
• Iterating through a file using for line in f is much better than for line in f.readlines(). The former is pythonic (e.g., would work if f is any generic iterable; not necessarily a file object that implements readlines), and more efficient f.readlines() creates an list with the entire file in memory and then iterates through it. * if search_phrase in line is more pythonic than if line.find(search_phrase) >= 0, as it doesn't require line to implement find, reads more easily to see what's intended, and isn't easily screwed up (e.g., if line.find(search_phrase) and if line.find(search_phrase) > 0 both will not work for all cases as find returns the index of the first match or -1).
• Its simpler/cleaner to wrap an iterated item in enumerate like for i, line in enumerate(f) than to initialize line_num = 0 before the loop and then manually increment in the loop. (Though arguably, this is more difficult to read for people unfamiliar with enumerate.)

If the favicon is a png type image, it'll not work in older versions of Chrome. However it'll work just fine in FireFox. Also, don't forget to clear your browser cache while working on such things. Many a times, code is just fine, but cache is the real culprit.

If you really need it...

html { overflow-y: hidden; }

(I wanted to point this out even though I'm late to the party)
The original question you were trying to find a 'Not IN' essentially. It looks like is not supported from the research (2 links below) that I was doing.

So if you wanted to do a 'Not In':

("merchant_id" in x)
true
("merchant_id_NotInObject" in x)
false 

I'd recommend just setting that expression == to what you're looking for

if (("merchant_id" in thisSession)==false)
{
    // do nothing.
}
else 
{

and then back to normal again

$("body").css("cursor", "default");

You should be able to read the GUID attribute of the assembly via reflection. This will get the GUID for the current assembly

Assembly asm = Assembly.GetExecutingAssembly();
var attribs = (asm.GetCustomAttributes(typeof(GuidAttribute), true));
Console.WriteLine((attribs[0] as GuidAttribute).Value);

You can replace the GuidAttribute with other attributes as well, if you want to read things like AssemblyTitle, AssemblyVersion, etc.

You can also load another assembly (Assembly.LoadFrom and all) instead of getting the current assembly - if you need to read these attributes of external assemblies (for example, when loading a plugin).

Follow the below steps,

1. npm install -g http-server, install the http-server in angular project.
2. Go to file location which needs to be accessed and open cmd prompt, use cmd http-server ./
3. Access any of the paths with port number in browser(ex: 120.0.0.1:8080) 4.now in your angular application use the path "http://120.0.0.1:8080/filename" Worked fine for me

The varStatus references to LoopTagStatus which has a getIndex() method.

So:

<c:forEach var="tableEntity" items='${requestScope.tables}' varStatus="outer">
   <c:forEach var="rowEntity" items='${tableEntity.rows}' varStatus="inner">            
        <c:out value="${(outer.index * fn:length(tableEntity.rows)) + inner.index}" />
    </c:forEach>
</c:forEach>

Found this useful explanation from http://ng-learn.org/2013/11/Bower-vs-npm/

On one hand npm was created to install modules used in a node.js environment, or development tools built using node.js such Karma, lint, minifiers and so on. npm can install modules locally in a project ( by default in node_modules ) or globally to be used by multiple projects. In large projects the way to specify dependencies is by creating a file called package.json which contains a list of dependencies. That list is recognized by npm when you run npm install, which then downloads and installs them for you.

On the other hand bower was created to manage your frontend dependencies. Libraries like jQuery, AngularJS, underscore, etc. Similar to npm it has a file in which you can specify a list of dependencies called bower.json. In this case your frontend dependencies are installed by running bower install which by default installs them in a folder called bower_components.

As you can see, although they perform a similar task they are targeted to a very different set of libraries.

There is a nice package called mat4py which can easily be installed using

pip install mat4py

It is straightforward to use (from the website):

Load data from a MAT-file

The function loadmat loads all variables stored in the MAT-file into a simple Python data structure, using only Python’s dict and list objects. Numeric and cell arrays are converted to row-ordered nested lists. Arrays are squeezed to eliminate arrays with only one element. The resulting data structure is composed of simple types that are compatible with the JSON format.

Example: Load a MAT-file into a Python data structure:

from mat4py import loadmat

data = loadmat('datafile.mat')

The variable data is a dict with the variables and values contained in the MAT-file.

Save a Python data structure to a MAT-file

Python data can be saved to a MAT-file, with the function savemat. Data has to be structured in the same way as for loadmat, i.e. it should be composed of simple data types, like dict, list, str, int, and float.

Example: Save a Python data structure to a MAT-file:

from mat4py import savemat

savemat('datafile.mat', data)

The parameter data shall be a dict with the variables.

Specify the optional selector to target what you want:

jQuery(this).parent('li').addClass('yourClass');

Or:

jQuery(this).parents('li').addClass('yourClass');

I know this is an old question but for people searching for this solution it's worth noting that you should not use append() to add content to a textarea. the append() method targets innerHTML not the value of the textarea. The content may appear in the textarea but it will not be added to the element's form value.

As noted above using:

$('#textarea').val($('#textarea').val()+'new content'); 

will work fine.

Oracle as well as modern versions of Ubuntu have moved to newer versions of Java. The default for Ubuntu 20.04 is OpenJDK 11 which is good enough for most purposes.

If you really need it for running legacy programs, OpenJDK 8 is also available for Ubuntu 20.04 from the official repositories.

If you really need exactly Java 7, the best bet as of 2020 is to download a Zulu distribution. The easiest to install if you have root privileges is the .DEB version, otherwise download the .ZIP one.

When we use the ascii() it escapes the non-ascii characters and it doesn't change ascii characters correctly. So my main thought is, it doesn't change the ASCII characters, so I am iterating through the string and checking if the character is changed. If it changed then replacing it with the replacer, what you give.
For example: ' '(a single space) or '?' (with a question mark).

def remove(x, replacer):

     for i in x:
        if f"'{i}'" == ascii(i):
            pass
        else:
            x=x.replace(i,replacer)
     return x
remove('hái',' ')

Result: "h i" (with single space between).

Syntax : remove(str,non_ascii_replacer)
str = Here you will give the string you want to work with.
non_ascii_replacer = Here you will give the replacer which you want to replace all the non ASCII characters with.

A C++17 solution: full type safety + nice calling syntax

Since the introduction of variadic templates in C++11 and fold expressions in C++17, it is possible to define a template-function which, at the caller site, is callable as if it was a varidic function but with the advantages to:

• be strongly type safe;
• work without the run-time information of the number of arguments, or without the usage of a "stop" argument.

Here is an example for mixed argument types

template<class... Args>
void print(Args... args)
{
    (std::cout << ... << args) << "\n";
}
print(1, ':', " Hello", ',', " ", "World!");

And another with enforced type match for all arguments:

#include <type_traits> // enable_if, conjuction

template<class Head, class... Tail>
using are_same = std::conjunction<std::is_same<Head, Tail>...>;

template<class Head, class... Tail, class = std::enable_if_t<are_same<Head, Tail...>::value, void>>
void print_same_type(Head head, Tail... tail)
{
    std::cout << head;
    (std::cout << ... << tail) << "\n";
}
print_same_type("2: ", "Hello, ", "World!");   // OK
print_same_type(3, ": ", "Hello, ", "World!"); // no matching function for call to 'print_same_type(int, const char [3], const char [8], const char [7])'
                                               // print_same_type(3, ": ", "Hello, ", "World!");
                                                                                              ^

If your page is deeply pathed or might move around and your JS script is at "~/JS/Registration.js" of your web folder, you can try the following:

<script src='<%=ResolveClientUrl("~/JS/Registration.js") %>'

I fixed this error by inserting these lines of code:

  <scope>test</scope>
</dependency>

into <dependencies> node.

You should include it inside quotes '\n', See below,

console.log('roleName = '+roleName+ '\n' + 
             'role_ID = '+role_ID+  '\n' + 
             'modal_ID = '+modal_ID+ '\n' +  
             'related = '+related);

I don't know if you can do it on-demand, but you can enable the option "Track Active Item in Solution Explorer" (Tools->Options->Projects and Solutions->General) which will always select the active tab item in the solution explorer.

• GitHub

  git config --global url.ssh://[email protected]/.insteadOf https://github.com/
  

• BitBucket

  git config --global url.ssh://[email protected]/.insteadOf https://bitbucket.org/
  

That tells git to always use SSH instead of HTTPS when connecting to GitHub/BitBucket, so you'll authenticate by certificate by default, instead of being prompted for a password.

go run . will run all of your files. The entry point is the function main() which has to be unique to the main package.

Another option is to build the binary with go build and run it.

Adding origin=${window.location.host} or "*" is not enough.

Add https:// before it and it will work.

Also, make sure that you are using an URL that can be embedded: take the video ID out and concatenate a string that has the YouTube video prefix and the video ID + embed definition.

Get cask

brew tap caskroom/cask

Install java7:

brew tap caskroom/versions
brew cask install java7

(I had difficulty finding the download link of java7 on oracle website, as they're just "recommending" java8 )

EDIT January 2018 (As pointed by Ankur):

Use zulu7 cask. Zulu is a certified build of OpenJDK produced by Azul Systems that should be around for a long time (they even offer JDK6 builds still).

brew cask install caskroom/versions/zulu7

If you want to add a flag to every link, e.g. -fsanitize=address then I would not recommend using CMAKE_*_LINKER_FLAGS. Even with them all set it still doesn't use the flag when linking a framework on OSX, and maybe in other situations. Instead use link_libraries():

add_compile_options("-fsanitize=address")
link_libraries("-fsanitize=address")

This works for everything.

You need to deserialize your form data before passing it as the second parameter to .post (). You can achieve this using jQuery's $.param (data) method. Then you will be able to on server side to reference it like $.POST ['email'];

Nice answers. You could also set Jobs (i.e., commands) with "Crontab" for more flexibility (which provides different options to run scripts, loggin the outputs, etc.), although it requires more time to be understood and set properly:

• How to run a command on startup in Ubuntu?

• The Beginners Guide To Cron Jobs

Using '@reboot' you can Run a command once, at startup.

Wrapping up: run $ sudo crontab -e -u root

And add a line at the end of the file with your command as follows:

@reboot sudo searchd

MySQL provides comprehensive character set management that can help with this kind of problem.

SELECT whatever
  FROM tableName 
 WHERE columnToCheck <> CONVERT(columnToCheck USING ASCII)

The CONVERT(col USING charset) function turns the unconvertable characters into replacement characters. Then, the converted and unconverted text will be unequal.

See this for more discussion. https://dev.mysql.com/doc/refman/8.0/en/charset-repertoire.html

You can use any character set name you wish in place of ASCII. For example, if you want to find out which characters won't render correctly in code page 1257 (Lithuanian, Latvian, Estonian) use CONVERT(columnToCheck USING cp1257)

In case we want to dump the in memory file to disk. This code can be used

  if isinstanceof(obj,SpooledTemporaryFile):
    obj.rollover()

It isn't clear what you're asking for. I don't know what 'with respect to the web application we are using' means if getServletContext().getRealPath() isn't the answer, but:

• The current user's current working directory is given by System.getProperty("user.dir")
• The current user's home directory is given by System.getProperty("user.home")
• The location of the JAR file from which the current class was loaded is given by this.getClass().getProtectionDomain().getCodeSource().getLocation().

Please check if JIRA status in "In Development". For me , it was not , when i changed jira status to "In Development", it worked for me.

Make sure that your sas.png is marked as Build Action: Content and Copy To Output Directory: Copy Always in its Visual Studio Properties...

I think the C# source code goes like this...

Image image = new Image();
image.Source = (new ImageSourceConverter()).ConvertFromString("pack://application:,,,/Bilder/sas.png") as ImageSource;

and XAML should be

<Image Height="200" HorizontalAlignment="Left" Margin="12,12,0,0" 
       Name="image1" Stretch="Fill" VerticalAlignment="Top" 
       Source="../Bilder/sas.png"
       Width="350" />  

EDIT

Dynamically I think XAML would provide best way to load Images ...

<Image Source="{Binding Converter={StaticResource MyImageSourceConverter}}"
       x:Name="MyImage"/>

where image.DataContext is string path.

MyImage.DataContext = "pack://application:,,,/Bilder/sas.png";

public class MyImageSourceConverter : IValueConverter
{
    public object Convert(object value_, Type targetType_, 
    object parameter_, System.Globalization.CultureInfo culture_)
    {
        return (new ImageSourceConverter()).ConvertFromString (value.ToString());
    }

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

Now as you set a different data context, Image would be automatically loaded at runtime.

So this is probably waaaaaay late to the party but the actual problem is an error or rather the repetition of the same error in three batch files.

C:\Program Files(x86)\Microsoft Visual Studio 10.0\Common7\Tools\VCVarsQueryRegistry.bat

C:\Program Files(x86)\Microsoft Visual Studio 10.0\Common7\Tools\vsvars32.bat

C:\Program Files(x86)\Microsoft Visual Studio 10.0\VC\bin\vcvars32.bat

The pattern of the error is everywhere a for loop is used to loop through registry values. It looks like this:

@for /F "tokens=1,2*" %%i in ('reg query "%1\SOFTWARE\Microsoft\VisualStudio\SxS\VS7" /v "10.0"') DO (
    @if "%%i"=="10.0" (
        @SET "VS100COMNTOOLS=%%k"
    )
)

The problem is the second occurrence of %%i. The way the loop construct works is the first %% variable is the first token, the next is the second and so on. So the second %%i should be a %%j (or whatever you want) so that it points to the value that would possibly be a "10.0". You can tell the developer wanted to use i,j,k as the values because in the enclosed @SET in the if, they use %%k. Which would be the path.

So, in short, go through all these types of loops in the three files above and change the second occurrence of %%i to %%k and everything will work like it's supposed to. So it should look like this:

@for /F "tokens=1,2*" %%i in ('reg query "%1\SOFTWARE\Microsoft\VisualStudio\SxS\VS7" /v "10.0"') DO (
    @if "%%j"=="10.0" (
        @SET "VS100COMNTOOLS=%%k"
    )
)

Hope this helps. Not sure if this applies to all versions. I only know that it does apply to VS 2010 (SP1).

You can't free types that aren't dynamically allocated. Although arrays are syntactically similar (int* x = malloc(sizeof(int) * 4) can be used in the same way that int x[4] is), calling free(firstName) would likely cause an error for the latter.

For example, take this code:

int x;
free(&x);

free() is a function which takes in a pointer. &x is a pointer. This code may compile, even though it simply won't work.

If we pretend that all memory is allocated in the same way, x is "allocated" at the definition, "freed" at the second line, and then "freed" again after the end of the scope. You can't free the same resource twice; it'll give you an error.

This isn't even mentioning the fact that for certain reasons, you may be unable to free the memory at x without closing the program.

tl;dr: Just free the struct and you'll be fine. Don't call free on arrays; only call it on dynamically allocated memory.

Plain and simple:

plt.plot(x, y, 'r-', alpha=0.7)

(I know I add nothing new, but the straightforward answer should be visible).

I've used the following JavaScript library with great success:

https://github.com/balupton/jquery-history

It supports the HTML5 history API as well as a fallback method (using #) for older browsers.

This library is essentially a polyfill around `history.pushState'.

I came across System.Runtime.InteropServices.COMException while opening a project solution. Sometimes user doesn't have enough priveleges to run some COM Methods. I ran Visual Studio as Administrator and the exception was gone.

Using the awesome psutil library it's pretty simple:

p = psutil.Process(pid)
p.terminate()  #or p.kill()

If you don't want to install a new library, you can use the os module:

import os
import signal

os.kill(pid, signal.SIGTERM) #or signal.SIGKILL 

See also the os.kill documentation.

If you are interested in starting the command python StripCore.py if it is not running, and killing it otherwise, you can use psutil to do this reliably.

Something like:

import psutil
from subprocess import Popen

for process in psutil.process_iter():
    if process.cmdline() == ['python', 'StripCore.py']:
        print('Process found. Terminating it.')
        process.terminate()
        break
else:
    print('Process not found: starting it.')
    Popen(['python', 'StripCore.py'])

Sample run:

$python test_strip.py   #test_strip.py contains the code above
Process not found: starting it.
$python test_strip.py 
Process found. Terminating it.
$python test_strip.py 
Process not found: starting it.
$killall python
$python test_strip.py 
Process not found: starting it.
$python test_strip.py 
Process found. Terminating it.
$python test_strip.py 
Process not found: starting it.

Note: In previous psutil versions cmdline was an attribute instead of a method.

According to 508 compliance (for screen readers for visually impared), tables should only be used to hold data and not for layout as it causes the screen readers to freak out. Or so I've been told.

If you assign names to each of the divs, you can skin them all together using CSS as well. They're just a bit more of a pain to get to sit the way you need them to.

string inLine = reader.ReadToEnd();
myList = inLine.Split(new string[] { "\r\n" }, StringSplitOptions.None).ToList();

I also use the Environment.NewLine.toCharArray as well, but found that didn't work on a couple files that did end in \r\n. Try either one and I hope it works well for you.

You can output special color control codes to get colored terminal output, here's a good resource on how to print colors.

For example:

printf("\033[22;34mHello, world!\033[0m");  // shows a blue hello world

EDIT: My original one used prompt color codes, which doesn't work :( This one does (I tested it).

I tried out the accepted answer but I still had a problem with the content alignment. Adding a ":before" selector as shown below fixed the issue:

// LESS HELPER
.clearfix()
{
    &:after, &:before{
       content: " "; /* Older browser do not support empty content */
       visibility: hidden;
       display: block;
       height: 0;
       clear: both;
    }
}

LESS above will compile to CSS below:

clearfix:after,
clearfix:before {
  content: " ";
  /* Older browser do not support empty content */
  visibility: hidden;
  display: block;
  height: 0;
  clear: both;
}

Since you added a new property to the model, you must first delete the database. Then manage.py migrations then manage.py migrate.

Unexpected T_STRING

T_STRING is a bit of a misnomer. It does not refer to a quoted "string". It means a raw identifier was encountered. This can range from bare words to leftover CONSTANT or function names, forgotten unquoted strings, or any plain text.

1. Misquoted strings

   This syntax error is most common for misquoted string values however. Any unescaped and stray " or ' quote will form an invalid expression:

                  ?                  ?
    echo "<a href="http://example.com">click here</a>";
   

   Syntax highlighting will make such mistakes super obvious. It's important to remember to use backslashes for escaping \" double quotes, or \' single quotes - depending on which was used as string enclosure.

   • For convenience you should prefer outer single quotes when outputting plain HTML with double quotes within.
   • Use double quoted strings if you want to interpolate variables, but then watch out for escaping literal " double quotes.
   • For lengthier output, prefer multiple echo/print lines instead of escaping in and out. Better yet consider a HEREDOC section.

   
   Another example is using PHP entry inside HTML code generated with PHP:

   $text = '<div>some text with <?php echo 'some php entry' ?></div>'
   

   This happens if $text is large with many lines and developer does not see the whole PHP variable value and focus on the piece of code forgetting about its source. Example is here

   See also What is the difference between single-quoted and double-quoted strings in PHP?.

2. Unclosed strings

   If you miss a closing " then a syntax error typically materializes later. An unterminated string will often consume a bit of code until the next intended string value:

                                                          ?
   echo "Some text", $a_variable, "and some runaway string ;
   success("finished");
            ?
   

   It's not just literal T_STRINGs which the parser may protest then. Another frequent variation is an Unexpected '>' for unquoted literal HTML.

3. Non-programming string quotes

   If you copy and paste code from a blog or website, you sometimes end up with invalid code. Typographic quotes aren't what PHP expects:

   $text = ’Something something..’ + ”these ain't quotes”;
   

   Typographic/smart quotes are Unicode symbols. PHP treats them as part of adjoining alphanumeric text. For example ”these is interpreted as a constant identifier. But any following text literal is then seen as a bareword/T_STRING by the parser.

4. The missing semicolon; again

   If you have an unterminated expression in previous lines, then any following statement or language construct gets seen as raw identifier:

          ?
   func1()
   function2();
   

   PHP just can't know if you meant to run two functions after another, or if you meant to multiply their results, add them, compare them, or only run one || or the other.

5. Short open tags and <?xml headers in PHP scripts

   This is rather uncommon. But if short_open_tags are enabled, then you can't begin your PHP scripts with an XML declaration:

         ?
   <?xml version="1.0"?>
   

   PHP will see the <? and reclaim it for itself. It won't understand what the stray xml was meant for. It'll get interpreted as constant. But the version will be seen as another literal/constant. And since the parser can't make sense of two subsequent literals/values without an expression operator in between, that'll be a parser failure.

6. Invisible Unicode characters

   A most hideous cause for syntax errors are Unicode symbols, such as the non-breaking space. PHP allows Unicode characters as identifier names. If you get a T_STRING parser complaint for wholly unsuspicious code like:

   <?php
       print 123;
   

   You need to break out another text editor. Or an hexeditor even. What looks like plain spaces and newlines here, may contain invisible constants. Java-based IDEs are sometimes oblivious to an UTF-8 BOM mangled within, zero-width spaces, paragraph separators, etc. Try to reedit everything, remove whitespace and add normal spaces back in.

   You can narrow it down with with adding redundant ; statement separators at each line start:

   <?php
       ;print 123;
   

   The extra ; semicolon here will convert the preceding invisible character into an undefined constant reference (expression as statement). Which in return makes PHP produce a helpful notice.

7. The `$` sign missing in front of variable names

   Variables in PHP are represented by a dollar sign followed by the name of the variable.

   The dollar sign ($) is a sigil that marks the identifier as a name of a variable. Without this sigil, the identifier could be a language keyword or a constant.

   This is a common error when the PHP code was "translated" from code written in another language (C, Java, JavaScript, etc.). In such cases, a declaration of the variable type (when the original code was written in a language that uses typed variables) could also sneak out and produce this error.

8. Escaped Quotation marks

   If you use \ in a string, it has a special meaning. This is called an "Escape Character" and normally tells the parser to take the next character literally.

   Example: echo 'Jim said \'Hello\''; will print Jim said 'hello'

   If you escape the closing quote of a string, the closing quote will be taken literally and not as intended, i.e. as a printable quote as part of the string and not close the string. This will show as a parse error commonly after you open the next string or at the end of the script.

   Very common error when specifiying paths in Windows: "C:\xampp\htdocs\" is wrong. You need "C:\\xampp\\htdocs\\".

9. Typed properties

   You need PHP =7.4 to use property typing such as:

   public stdClass $obj;
   

It's possible to run application specifying package name only using monkey tool by follow this pattern:

adb shell monkey -p your.app.package.name -c android.intent.category.LAUNCHER 1

Command is used to run app using monkey tool which generates random input for application. The last part of command is integer which specify the number of generated random input for app. In this case the number is 1, which in fact is used to launch the app (icon click).

You can try this in round_tv.xml in drawable folder:

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

    <stroke android:color="#22ff55" android:width="3dip"/>

    <corners
        android:bottomLeftRadius="30dp"
        android:bottomRightRadius="30dp"
        android:topLeftRadius="30dp"
        android:topRightRadius="30dp" />

    <size
        android:height="60dp"
        android:width="60dp" />

</shape>

Apply that drawable in your textviews as:

<TextView
    android:id="@+id/tv"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/round_tv"
    android:gravity="center_vertical|center_horizontal"
    android:text="ddd"
    android:textColor="#000"
    android:textSize="20sp" />

Output:

Hope this helps.

Edit: If your text is too long, Oval shape is more preferred.

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

    <stroke android:color="#55ff55" android:width="3dip"/>

    <corners
        android:bottomLeftRadius="30dp"
        android:bottomRightRadius="30dp"
        android:topLeftRadius="30dp"
        android:topRightRadius="30dp" />

    <size
        android:height="60dp"
        android:width="60dp" />

</shape>

Output:

If you still need it a proper circle, then I guess you will need to set its height dynamically after setting text in it, new height should be as much as its new width so as to make a proper circle.

It should be legal to put a semicolon directly before the WITH keyword.

Also; auto it = std::next(v.begin(), index);

Update: Needs a C++11x compliant compiler

Can you try this,

var ajaxSubmit = function(formE1) {

            var password = $.trim($('#employee_password').val());

             $.ajax({
                type: "POST",
                async: "false",
                url: "checkpass.php",
                data: "password="+password,
                success: function(html) {
                    var arr=$.parseJSON(html);
                    if(arr == "Successful")
                    { 
                         **$("form[name='form']").submit();**
                        return true;
                    }
                    else
                    {    return false;
                    }
                }
            });
              **return false;**
        }

In addition mysql passwords when not using the IDENTIFIED BY clause, may be blank values, if non-blank, they may be encrypted. But yes USAGE is used to modify an account by granting simple resource limiters such as MAX_QUERIES_PER_HOUR, again this can be specified by also using the WITH clause, in conjuction with GRANT USAGE(no privileges added) or GRANT ALL, you can also specify GRANT USAGE at the global level, database level, table level,etc....

As @Bozho stated, it is possible to do it if debug information is included during compilation. There's a good answer here...

How to get the parameter names of an object's constructors (reflection)? by @AdamPaynter

...using the ASM library. I put together an example showing how you can achieve your goal.

First of all, start with a pom.xml with these dependencies.

<dependency>
    <groupId>org.ow2.asm</groupId>
    <artifactId>asm-all</artifactId>
    <version>5.2</version>
</dependency>
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>

Then, this class should do what you want. Just invoke the static method getParameterNames().

import org.objectweb.asm.ClassReader;
import org.objectweb.asm.Type;
import org.objectweb.asm.tree.ClassNode;
import org.objectweb.asm.tree.LocalVariableNode;
import org.objectweb.asm.tree.MethodNode;

public class ArgumentReflection {
    /**
     * Returns a list containing one parameter name for each argument accepted
     * by the given constructor. If the class was compiled with debugging
     * symbols, the parameter names will match those provided in the Java source
     * code. Otherwise, a generic "arg" parameter name is generated ("arg0" for
     * the first argument, "arg1" for the second...).
     * 
     * This method relies on the constructor's class loader to locate the
     * bytecode resource that defined its class.
     * 
     * @param theMethod
     * @return
     * @throws IOException
     */
    public static List<String> getParameterNames(Method theMethod) throws IOException {
        Class<?> declaringClass = theMethod.getDeclaringClass();
        ClassLoader declaringClassLoader = declaringClass.getClassLoader();

        Type declaringType = Type.getType(declaringClass);
        String constructorDescriptor = Type.getMethodDescriptor(theMethod);
        String url = declaringType.getInternalName() + ".class";

        InputStream classFileInputStream = declaringClassLoader.getResourceAsStream(url);
        if (classFileInputStream == null) {
            throw new IllegalArgumentException(
                    "The constructor's class loader cannot find the bytecode that defined the constructor's class (URL: "
                            + url + ")");
        }

        ClassNode classNode;
        try {
            classNode = new ClassNode();
            ClassReader classReader = new ClassReader(classFileInputStream);
            classReader.accept(classNode, 0);
        } finally {
            classFileInputStream.close();
        }

        @SuppressWarnings("unchecked")
        List<MethodNode> methods = classNode.methods;
        for (MethodNode method : methods) {
            if (method.name.equals(theMethod.getName()) && method.desc.equals(constructorDescriptor)) {
                Type[] argumentTypes = Type.getArgumentTypes(method.desc);
                List<String> parameterNames = new ArrayList<String>(argumentTypes.length);

                @SuppressWarnings("unchecked")
                List<LocalVariableNode> localVariables = method.localVariables;
                for (int i = 1; i <= argumentTypes.length; i++) {
                    // The first local variable actually represents the "this"
                    // object if the method is not static!
                    parameterNames.add(localVariables.get(i).name);
                }

                return parameterNames;
            }
        }

        return null;
    }
}

Here's an example with a unit test.

public class ArgumentReflectionTest {

    @Test
    public void shouldExtractTheNamesOfTheParameters3() throws NoSuchMethodException, SecurityException, IOException {

        List<String> parameterNames = ArgumentReflection
                .getParameterNames(Clazz.class.getMethod("callMe", String.class, String.class));
        assertEquals("firstName", parameterNames.get(0));
        assertEquals("lastName", parameterNames.get(1));
        assertEquals(2, parameterNames.size());

    }

    public static final class Clazz {

        public void callMe(String firstName, String lastName) {
        }

    }
}

You can find the complete example on GitHub

Caveats

• I slightly changed the original solution from @AdamPaynter to make it work for Methods. If I properly understood, his solution works only with constructors.
• This solution does not work with static methods. This is becasue in this case the number of arguments returned by ASM is different, but it something that can be easily fixed.

Here is a function that will load CSS files with a success or failure callback. The failure callback will be called just once, if one or more resources fail to load. I think this approach is better than some of the other solutions because inserting a element into the DOM with an HREF causes an additional browser request (albeit, the request will likely come from cache, depending on response headers).

function loadCssFiles(urls, successCallback, failureCallback) {

    $.when.apply($,
        $.map(urls, function(url) {
            return $.get(url, function(css) {
                $("<style>" + css + "</style>").appendTo("head");
            });
        })
    ).then(function() {
        if (typeof successCallback === 'function') successCallback();
    }).fail(function() {
        if (typeof failureCallback === 'function') failureCallback();
    });

}

Usage as so:

loadCssFiles(["https://test.com/style1.css", "https://test.com/style2.css",],
    function() {
    alert("All resources loaded");
}, function() {
    alert("One or more resources failed to load");
});

Here is another function that will load both CSS and javascript files:

function loadJavascriptAndCssFiles(urls, successCallback, failureCallback) {

    $.when.apply($,
        $.map(urls, function(url) {
            if(url.endsWith(".css")) {
                return $.get(url, function(css) {
                    $("<style>" + css + "</style>").appendTo("head");
                });
            } else {
                return $.getScript(url);
            }
        })
    ).then(function() {
        if (typeof successCallback === 'function') successCallback();
    }).fail(function() {
        if (typeof failureCallback === 'function') failureCallback();
    });

}

The binary 32 bits for 00101011 is

00000000 00000000 00000000 00101011, and the result is:

  00000000 00000000 00000000 00101011   >> 2(times)
 \\                                 \\
  00000000 00000000 00000000 00001010

Shifts the bits of 43 to right by distance 2; fills with highest(sign) bit on the left side.

Result is 00001010 with decimal value 10.

00001010
    8+2 = 10

Solution by Mosh Hamedani

Creating a StopWatch function constructor.

Define 4 local variables

1. startTime
2. endTime
3. isRunning
4. duration set to 0

Next create 3 methods

1. start
2. stop
3. reset

start method

• check if isRunning is true if so throw an error that start cannot be called twice.
• set isRunning to true
• assign the current Date object to startTime.

stop method

• check if isRunning is false if so throw an error that stop cannot be called twice.
• set isRunning to false
• assign the current Date object to endTime.
• calculate the seconds by endTime and startTime Date object
• increment duration with seconds

reset method:

• reset all the local variables.

Read-only property

if you want to access the duration local variable you need to define a property using Object.defineProperty. It's useful when you want to create a read-only property.

Object.defineProperty takes 3 parameters

• the object which to define a property (in this case the current object (this))
• the name of the property

• the value of the key property.

• We want to create a Read-only property so we pass an object as a value. The object contain a get method that return the duration local variable. in this way we cannot change the property only get it.

The trick is to use Date() object to calculate the time.

Reference the code below

function StopWatch() {


let startTime,
    endTime,
    isRunning,
    duration = 0;

  this.start = function () {
    if (isRunning) throw new Error("StopWatch has already been started.");

    isRunning = true;

    startTime = new Date();
  };



this.stop = function () {
    if (!isRunning) throw new Error("StopWatch has already been stop.");

    isRunning = false;

    endTime = new Date();

    const seconds = (endTime.getTime() - startTime.getTime()) / 1000;
    duration += seconds;
  };

  this.reset = function () {
    duration = 0;
    startTime = null;
    endTime = null;
    isRunning = false;
  };

  Object.defineProperty(this, "duration", {
    get: function () {
      return duration;
    },
  });
}

const sw = new StopWatch();

If you want to define a 3D matrix containing all zeros, you write

A = zeros(8,4,20);

All ones uses ones, all NaN's uses NaN, all false uses false instead of zeros.

If you have an existing 2D matrix, you can assign an element in the "3rd dimension" and the matrix is augmented to contain the new element. All other new matrix elements that have to be added to do that are set to zero.

For example

B = magic(3); %# creates a 3x3 magic square
B(2,1,2) = 1; %# and you have a 3x3x2 array

If your search is over several years, and you still want to group monthly, I suggest:

version #1:

SELECT SQL_NO_CACHE YEAR(record_date), MONTH(record_date), COUNT(*)
FROM stats
GROUP BY DATE_FORMAT(record_date, '%Y%m')

version #2 (more efficient):

SELECT SQL_NO_CACHE YEAR(record_date), MONTH(record_date), COUNT(*)
FROM stats
GROUP BY YEAR(record_date)*100 + MONTH(record_date)

I compared these versions on a big table with 1,357,918 rows (innodb), and the 2nd version appears to have better results.

version1 (average of 10 executes): 1.404 seconds
version2 (average of 10 executes): 0.780 seconds

(SQL_NO_CACHE key added to prevent MySQL from CACHING to queries.)

SQLAlchemy upsert for Postgres >=9.5

Since the large post above covers many different SQL approaches for Postgres versions (not only non-9.5 as in the question), I would like to add how to do it in SQLAlchemy if you are using Postgres 9.5. Instead of implementing your own upsert, you can also use SQLAlchemy's functions (which were added in SQLAlchemy 1.1). Personally, I would recommend using these, if possible. Not only because of convenience, but also because it lets PostgreSQL handle any race conditions that might occur.

Cross-posting from another answer I gave yesterday (https://stackoverflow.com/a/44395983/2156909)

SQLAlchemy supports ON CONFLICT now with two methods on_conflict_do_update() and on_conflict_do_nothing():

Copying from the documentation:

from sqlalchemy.dialects.postgresql import insert

stmt = insert(my_table).values(user_email='[email protected]', data='inserted data')
stmt = stmt.on_conflict_do_update(
    index_elements=[my_table.c.user_email],
    index_where=my_table.c.user_email.like('%@gmail.com'),
    set_=dict(data=stmt.excluded.data)
    )
conn.execute(stmt)

Sometime when you downloading a project from other people, they might have some special customization. So, in my case I downloaded this project https://github.com/thecodercoder/fem-easybank

And got these errors: Failed to load resource: net::ERR_FILE_NOT_FOUND That happed because the creator was using the /dist folder customization.

https://youtu.be/aoQ6S1a32j8?t=309

SOLUTION: you open Notepad++ press: Ctrl + F for search find all folders that starts with / as in the picture and replace with norma ones like: /dist/ to dist

Hello I was searching for a solution to reverse sorting a two dimensional numpy array, and I couldn't find anything that worked, but I think I have stumbled on a solution which I am uploading just in case anyone is in the same boat.

x=np.sort(array)
y=np.fliplr(x)

np.sort sorts ascending which is not what you want, but the command fliplr flips the rows left to right! Seems to work!

Hope it helps you out!

I guess it's similar to the suggest about -np.sort(-a) above but I was put off going for that by comment that it doesn't always work. Perhaps my solution won't always work either however I have tested it with a few arrays and seems to be OK.

There is a rule in Python programming called "it is Easier to Ask for Forgiveness than for Permission" (in short: EAFP). It means that you should catch exceptions instead of checking values for validity.

Thus, try the following:

try:
    qByUser = byUsrUrlObj.read()
    qUserData = json.loads(qByUser).decode('utf-8')
    questionSubjs = qUserData["all"]["questions"]
except ValueError:  # includes simplejson.decoder.JSONDecodeError
    print 'Decoding JSON has failed'

EDIT: Since simplejson.decoder.JSONDecodeError actually inherits from ValueError (proof here), I simplified the catch statement by just using ValueError.

I used ini_set('display_errors','off'); and it worked great.

Using LESS (not SCSS) and Angular 2.4.0 and standard Webpack (not Angular CLI, the following worked for me:

npm install --save font-awesome

and (in my app.component.less):

@import "~font-awesome/less/font-awesome.less";

and of course you may need this obvious and highly intuitive snippet (in module.loaders in webpack.conf)

        {
            test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)(\?(v=)?(\d+)(\.\d+)*)?$/,
            loader: 'file?name=graphics/[name].[ext]'
        },

The loader is there to fix webpack errors of the kind

"Module parse failed: \node_modules\font-awesome\fonts\fontawesome-webfont.svg?v=4.7.0 Unexpected token (1:0)" 

and the regexp matches those svg-references (with or without version specification). Depending on your webpack setup you might not need it or you may need something else.

Without seeing your code, it's hard to answer other than a stab in the dark. I would guess that the string you're passing to encodeURIComponent(), which is the correct method to use, is coming from the result of accessing the innerHTML property. The solution is to get the innerText/textContent property value instead:

var str, 
    el = document.getElementById("myUrl");

if ("textContent" in el)
    str = encodeURIComponent(el.textContent);
else
    str = encodeURIComponent(el.innerText);

If that isn't the case, you can use the replace() method to replace the HTML entity:

encodeURIComponent(str.replace(/&/g, "&"));

The answers presented here are largely technically correct, but even though the response list is long and this will be at the bottom I thought it was worth putting an actually correct response in here too, just in case somebody stumbles upon it and learns something valuable from it. It's not that the rest of the answers are wrong, it's just that they aren't right. And, to stop the hordes of trolls, yes, I know that technically these annotations are effectively the same thing and most interchangeable even unto spring 5. Now, for the right answer:

These three annotations are completely different things and are not interchangeable. You can tell that because there are three of them rather than just one. They are not intended to be interchangeable, they're just implemented that way out of elegance and convenience.

Modern programming is invention, art, technique, and communication, in varying proportions. The communication bit is usually very important because code is usually read much more often than its written. As a programmer you're not only trying to solve the technical problem, you're also trying to communicate your intent to future programmers who read your code. These programmers may not share your native language, nor your social environment, and it is possible that they may be reading your code 50-years in the future (it's not as unlikely as you may think). It's difficult to communicate effectively that far into the future. Therefore, it is vital that we use the clearest, most efficient, correct, and communicative language available to us. That we chose our words carefully to have maximum impact and to be as clear as possible as to our intent.

For example, it is vital that @Repository is used when we're writing a repository, rather than @Component. The latter is a very poor choice of annotation for a repository because it does not indicate that we're looking at a repository. We can assume that a repository is also a spring-bean, but not that a component is a repository. With @Repository we are being clear and specific in our language. We are stating clearly that this is a repository. With @Component we are leaving it to the reader to decide what type of component they are reading, and they will have to read the whole class (and possibly a tree of subclasses and interfaces) to infer meaning. The class could then possibly be misinterpreted by a reader in the distant future as not being a repository, and we would have been partially responsible for this mistake because we, who knew full well that this is a repository, failed to be specific in our language and communicate effectively our intent.

I won't go into the other examples, but will state as clearly as I can: these annotations are completely different things and should be used appropriately, as per their intent. @Repository is for storage repositories and no other annotation is correct. @Service is for services and no other annotation is correct. @Component is for components that are neither repositories nor services, and to use either of these in its place would also be incorrect. It might compile, it might even run and pass your tests, but it would be wrong and I would think less of you (professionally) if you were to do this.

There are examples of this throughout spring (and programming in general). You must not use @Controller when writing a REST API, because @RestController is available. You must not use @RequestMapping when @GetMapping is a valid alternative. Etc. Etc. Etc. You must chose the most specific exact and correct language you can to communicate your intent to your readers, otherwise, you are introducing risks into your system, and risk has a cost.

The If else statement needs to be wrapped in a .get or a .post to redirect. Such as

app.post('/login', function(req, res) {
});

or

app.get('/login', function(req, res) {
});

DISCLAIMER: The below solution does not preserve trailing tabs.

If you know the exact number of lines in the text file, try the following method:

@ECHO OFF
SET origfile=original file
SET tempfile=temporary file
SET insertbefore=4
SET totallines=200
<%origfile% (FOR /L %%i IN (1,1,%totallines%) DO (
  SETLOCAL EnableDelayedExpansion
  SET /P L=
  IF %%i==%insertbefore% ECHO(
  ECHO(!L!
  ENDLOCAL
)
) >%tempfile%
COPY /Y %tempfile% %origfile% >NUL
DEL %tempfile%

The loop reads lines from the original file one by one and outputs them. The output is redirected to a temporary file. When a certain line is reached, an empty line is output before it.

After finishing, the original file is deleted and the temporary one gets assigned the original name.

UPDATE

If the number of lines is unknown beforehand, you can use the following method to obtain it:

FOR /F %%C IN ('FIND /C /V "" ^<%origfile%') DO SET totallines=%%C

(This line simply replaces the SET totallines=200 line in the above script.)

The method has one tiny flaw: if the file ends with an empty line, the result will be the actual number of lines minus one. If you need a workaround (or just want to play safe), you can use the method described in this answer.

You can also use nvl(Column,0)

If obj is of type int[] say, then that will have an array Class but not be an instance of Object[]. So what do you want to do with obj. If you are going to cast it, go with instanceof. If you are going to use reflection, then use .getClass().isArray().

Best way is to use the Carbon dependency.

With Carbon\Carbon::now(); you get the current Datetime.

With Carbon you can do like enything with the DateTime. Event things like this:

$tomorrow = Carbon::now()->addDay();
$lastWeek = Carbon::now()->subWeek();

For my system, I had numerous IPv4 Addresses, only one of which was correct. A simple way to sort out and check it is as follows:

for /f "tokens=1,2* delims=:" %%A in ('ipconfig ^| find "IPv4 Address"') do (
    set "tempip=%%~B"
    set "tempip=!tempip: =!"
    ping !tempip! -n 1 -w 50
    if !errorlevel!==0 (
        set localip=!tempip!
        goto foundlocal
    )
)
:foundlocal

I recently had the requirement to use JNDI with an embedded Tomcat in Spring Boot.
Actual answers give some interesting hints to solve my task but it was not enough as probably not updated for Spring Boot 2.

Here is my contribution tested with Spring Boot 2.0.3.RELEASE.

Specifying a datasource available in the classpath at runtime

You have multiple choices :

• using the DBCP 2 datasource (you don't want to use DBCP 1 that is outdated and less efficient).
• using the Tomcat JDBC datasource.
• using any other datasource : for example HikariCP.

If you don't specify anyone of them, with the default configuration the instantiation of the datasource will throw an exception :

• To use Apache JDBC datasource, you don't need to add any dependency but you have to change the default factory class to org.apache.tomcat.jdbc.pool.DataSourceFactory.
  You can do it in the resource declaration : resource.setProperty("factory", "org.apache.tomcat.jdbc.pool.DataSourceFactory"); I will explain below where add this line.

• To use DBCP 2 datasource a dependency is required:

  <dependency> <groupId>org.apache.tomcat</groupId> <artifactId>tomcat-dbcp</artifactId> <version>8.5.4</version> </dependency>

Of course, adapt the artifact version according to your Spring Boot Tomcat embedded version.

• To use HikariCP, add the required dependency if not already present in your configuration (it may be if you rely on persistence starters of Spring Boot) such as :

  <dependency> <groupId>com.zaxxer</groupId> <artifactId>HikariCP</artifactId> <version>3.1.0</version> </dependency>

and specify the factory that goes with in the resource declaration:

resource.setProperty("factory", "com.zaxxer.hikari.HikariJNDIFactory");

Datasource configuration/declaration

You have to customize the bean that creates the TomcatServletWebServerFactory instance.
Two things to do :

• enabling the JNDI naming which is disabled by default

• creating and add the JNDI resource(s) in the server context

For example with PostgreSQL and a DBCP 2 datasource, do that :

@Bean
public TomcatServletWebServerFactory tomcatFactory() {
    return new TomcatServletWebServerFactory() {
        @Override
        protected TomcatWebServer getTomcatWebServer(org.apache.catalina.startup.Tomcat tomcat) {
            tomcat.enableNaming(); 
            return super.getTomcatWebServer(tomcat);
        }

        @Override 
        protected void postProcessContext(Context context) {

            // context
            ContextResource resource = new ContextResource();
            resource.setName("jdbc/myJndiResource");
            resource.setType(DataSource.class.getName());
            resource.setProperty("driverClassName", "org.postgresql.Driver");

            resource.setProperty("url", "jdbc:postgresql://hostname:port/dbname");
            resource.setProperty("username", "username");
            resource.setProperty("password", "password");
            context.getNamingResources()
                   .addResource(resource);          
        }
    };
}

Here the variants for Tomcat JDBC and HikariCP datasource.

In postProcessContext() set the factory property as explained early for Tomcat JDBC ds :

    @Override 
    protected void postProcessContext(Context context) {
        ContextResource resource = new ContextResource();       
        //...
        resource.setProperty("factory", "org.apache.tomcat.jdbc.pool.DataSourceFactory");
        //...
        context.getNamingResources()
               .addResource(resource);          
    }
};

and for HikariCP :

    @Override 
    protected void postProcessContext(Context context) {
        ContextResource resource = new ContextResource();       
        //...
        resource.setProperty("factory", "com.zaxxer.hikari.HikariDataSource");
        //...
        context.getNamingResources()
               .addResource(resource);          
    }
};

Using/Injecting the datasource

You should now be able to lookup the JNDI ressource anywhere by using a standard InitialContext instance :

InitialContext initialContext = new InitialContext();
DataSource datasource = (DataSource) initialContext.lookup("java:comp/env/jdbc/myJndiResource");

You can also use JndiObjectFactoryBean of Spring to lookup up the resource :

JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
bean.setJndiName("java:comp/env/jdbc/myJndiResource");
bean.afterPropertiesSet();
DataSource object = (DataSource) bean.getObject();

To take advantage of the DI container you can also make the DataSource a Spring bean :

@Bean(destroyMethod = "")
public DataSource jndiDataSource() throws IllegalArgumentException, NamingException {
    JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
    bean.setJndiName("java:comp/env/jdbc/myJndiResource");
    bean.afterPropertiesSet();
    return (DataSource) bean.getObject();
}

And so you can now inject the DataSource in any Spring beans such as :

@Autowired
private DataSource jndiDataSource;

Note that many examples on the internet seem to disable the lookup of the JNDI resource on startup :

bean.setJndiName("java:comp/env/jdbc/myJndiResource");
bean.setProxyInterface(DataSource.class);
bean.setLookupOnStartup(false);
bean.afterPropertiesSet(); 

But I think that it is helpless as it invokes just after afterPropertiesSet() that does the lookup !

You need the WHERE clause to replace ONLY the records that complies with the condition in the WHERE clause (as opposed to all records). You use % sign to indicate partial string: I.E.

LIKE ('...//domain1.com/images/%');

means all records that BEGIN with "...//domain1.com/images/" and have anything AFTER (that's the % for...)

Another example:

LIKE ('%http://domain1.com/images/%')

which means all records that contains "http://domain1.com/images/"

in any part of the string...

Make the following changes in your Registry and it should work:

1.) .NET Framework strong cryptography registry keys

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

2.) Secure Channel (Schannel) TLS 1.2 registry keys

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001

try this 100% working.

Log4net is saving into your project folder. Something like: \SolutionFolder\ProjectFolder\bin\SolutionConfiguration\logs\log-file.txt.

Where:

• SolutionFolder is where you save your solution
• ProjectFolder is the folder where your project lives into the solution and
• SolutionConfiguration is the folder that contais all the binaries of your project (the default is Debug or Release)

Hope this helps!

As alternative you always can try a simpler workaround, using another icon, for example:

<button type="button" style="background:none;border:none">
    <span class="fa fa-reorder"></span>
</button>

ref: https://www.w3schools.com/icons/fontawesome_icons_webapp.asp

<button type="button" style="background:none;border:none">
    <span class="glyphicon glyphicon-align-justify"></span>
</button>

ref: https://www.w3schools.com/icons/bootstrap_icons_glyphicons.asp

So you gain total control over their color and size:

button span {
    /*overwriting*/
    color: white;
    font-size: 25px;
}

(the button's style applied is just for a quick test):

I solved it by deleting "/.idea/libraries" from project. Thanks

Once you're logged in as postgres, you should be able to write:

psql -t -d database_name -c $'SELECT c_defaults FROM user_info WHERE c_uid = \'testuser\';'

to print out just the value of that field, which means that you can capture it to (for example) save in a Bash variable:

testuser_defaults="$(psql -t -d database_name -c $'SELECT c_defaults FROM user_info WHERE c_uid = \'testuser\';')"

To handle the logging in as postgres, I recommend using sudo. You can give a specific user the permission to run

sudo -u postgres /path/to/this/script.sh

so that they can run just the one script as postgres.

If you are converting to HTML, you can set the size of the image using HTML syntax using:

  <img src="path/to/image" height="400px" width="300px" />

or whatever height and width you would want to give.

I think I've accidentally found a solution. The only thing to do is inserting an empty <span class="input-group-addon"></span> between the <input> and the <select>.

Additionally you can make it "invisible" by reducing its width, horizontal padding and borders:

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
_x000D_
<div class="input-group">_x000D_
    <span class="input-group-addon" title="* Price" id="priceLabel">Price</span>_x000D_
    <input type="number" id="searchbygenerals_priceFrom" name="searchbygenerals[priceFrom]" required="required" class="form-control" value="0">_x000D_
    <span class="input-group-addon">-</span>_x000D_
    <input type="number" id="searchbygenerals_priceTo" name="searchbygenerals[priceTo]" required="required" class="form-control" value="0">_x000D_
  _x000D_
    <!-- insert this line -->_x000D_
    <span class="input-group-addon" style="width:0px; padding-left:0px; padding-right:0px; border:none;"></span>_x000D_
  _x000D_
    <select id="searchbygenerals_currency" name="searchbygenerals[currency]" class="form-control">_x000D_
        <option value="1">HUF</option>_x000D_
        <option value="2">EUR</option>_x000D_
    </select>_x000D_

Assuming these were datetime columns (if they're not apply to_datetime) you can just subtract them:

df['A'] = pd.to_datetime(df['A'])
df['B'] = pd.to_datetime(df['B'])

In [11]: df.dtypes  # if already datetime64 you don't need to use to_datetime
Out[11]:
A    datetime64[ns]
B    datetime64[ns]
dtype: object

In [12]: df['A'] - df['B']
Out[12]:
one   -58 days
two   -26 days
dtype: timedelta64[ns]

In [13]: df['C'] = df['A'] - df['B']

In [14]: df
Out[14]:
             A          B        C
one 2014-01-01 2014-02-28 -58 days
two 2014-02-03 2014-03-01 -26 days

Note: ensure you're using a new of pandas (e.g. 0.13.1), this may not work in older versions.

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:

export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).

Linting is a process by a linter program that analyzes source code in a particular programming language and flag potential problems like syntax errors, deviations from a prescribed coding style or using constructs known to be unsafe.

For example, a JavaScript linter would flag the first use of parseInt below as unsafe:

// without a radix argument - Unsafe
var count = parseInt(countString);

// with a radix paremeter specified - Safe
var count = parseInt(countString, 10);

let numericArray: number[] = [2, 3, 4, 1, 5, 8, 11];

let sortFn = (n1 , n2) => number { return n1 - n2; }

const sortedArray: number[] = numericArray.sort(sortFn);

Sort by some field:

let arr:{key:number}[] = [{key : 2}, {key : 3}, {key : 4}, {key : 1}, {key : 5}, {key : 8}, {key : 11}];

let sortFn2 = (obj1 , obj2) => {key:number} { return obj1.key - obj2.key; }

const sortedArray2:{key:number}[] = arr.sort(sortFn2);

Since the img is an inline element, Just use text-center on it's container. Using mx-auto will center the container (column) too.

<div class="row">
    <div class="col-4 mx-auto text-center">
        <img src="..">
    </div>
</div>

By default, images are display:inline. If you only want the center the image (and not the other column content), make the image display:block using the d-block class, and then mx-auto will work.

<div class="row">
  <div class="col-4">
    <img class="mx-auto d-block" src="..">
  </div>
</div>

Another way to do this would be to ignore the error with a declare continue handler:

delimiter ;;
create procedure foo ()
begin
    declare continue handler for 1060 begin end;
    alter table atable add subscriber_surname varchar(64);
end;;
call foo();;

I think its neater this way than with an exists subquery. Especially if you have a lot of columns to add, and you want to run the script several times.

more info on continue handlers can be found at http://dev.mysql.com/doc/refman/5.0/en/declare-handler.html

an alternative to this is Process hacker if you go into run as... (Interactive doesnt work for people with the security enhancments but that wont matter) and when box opens put Service into the box type and put SYSTEM into user box and put C:\Users\Windows\system32\cmd.exe leave the rest click ok and boch you have got a window with cmd on it and run as system now do the other steps for yourself because im suggesting you know them

You can simply use the WebDriver object, and access to the page source code via its @property field page_source...

Try this code snippet :-)

from selenium import webdriver
driver = webdriver.Firefox('path/to/executable')
driver.get('https://some-domain.com')
source = driver.page_source
if 'stuff' in source:
    print('found...')
else:
    print('not in source...')

I found there was another solution for this problem rather than creating a symbolic link.

You set the path to your directory, where libmysqlclient.18.dylib resides, to DYLD_LIBRARY_PATH environment variable. What I did is to put following line in my .bash_profile:

export DYLD_LIBRARY_PATH=/usr/local/mysql-5.5.15-osx10.6-x86/lib/:$DYLD_LIBRARY_PATH

That's it.

CLOCKS_PER_SEC is a constant which is declared in <time.h>. To get the CPU time used by a task within a C application, use:

clock_t begin = clock();

/* here, do your time-consuming job */

clock_t end = clock();
double time_spent = (double)(end - begin) / CLOCKS_PER_SEC;

Note that this returns the time as a floating point type. This can be more precise than a second (e.g. you measure 4.52 seconds). Precision depends on the architecture; on modern systems you easily get 10ms or lower, but on older Windows machines (from the Win98 era) it was closer to 60ms.

clock() is standard C; it works "everywhere". There are system-specific functions, such as getrusage() on Unix-like systems.

Java's System.currentTimeMillis() does not measure the same thing. It is a "wall clock": it can help you measure how much time it took for the program to execute, but it does not tell you how much CPU time was used. On a multitasking systems (i.e. all of them), these can be widely different.

Here are 4 ways to insert data into a table.

1. Simple insertion when the table column sequence is known.

   INSERT INTO Table1 VALUES (1,2,...)

2. Simple insertion into specified columns of the table.

   INSERT INTO Table1(col2,col4) VALUES (1,2)

3. Bulk insertion when...

   1. You wish to insert every column of Table2 into Table1
   2. You know the column sequence of Table2
   3. You are certain that the column sequence of Table2 won't change while this statement is being used (perhaps you the statement will only be used once).

   INSERT INTO Table1 {Column sequence} SELECT * FROM Table2

4. Bulk insertion of selected data into specified columns of Table2.

.

INSERT INTO Table1 (Column1,Column2 ....)
    SELECT Column1,Column2...
       FROM Table2

If you have a lot files to change in your projects you can create functions with the same names like mysql functions, and in the functions make the convert like this code:

$sql_host =     "your host";      
$sql_username = "username";    
$sql_password = "password";       
$sql_database = "database";       



$mysqli = new mysqli($sql_host , $sql_username , $sql_password , $sql_database );


/* check connection */
if ($mysqli->connect_errno) {
    printf("Connect failed: %s\n", $mysqli->connect_error);
    exit();
}


function mysql_query($query){
    $result = $mysqli->query($query);
    return $result;

}

function mysql_fetch_array($result){
    if($result){
        $row =  $result->fetch_assoc();
         return $row;
       }
}

function mysql_num_rows($result){
    if($result){
         $row_cnt = $result->num_rows;;
         return $row_cnt;
       }
}

A built-in Map type is now available in JavaScript. It can be used instead of simply using Object. It is supported by current versions of all major browsers.

Maps do not support the [subscript] notation used by Objects. That syntax implicitly casts the subscript value to a primitive string or symbol. Maps support any values as keys, so you must use the methods .get(key), .set(key, value) and .has(key).

var m = new Map();_x000D_
var key1 = 'key1';_x000D_
var key2 = {};_x000D_
var key3 = {};_x000D_
_x000D_
m.set(key1, 'value1');_x000D_
m.set(key2, 'value2');_x000D_
_x000D_
console.assert(m.has(key2), "m should contain key2.");_x000D_
console.assert(!m.has(key3), "m should not contain key3.");

Objects only supports primitive strings and symbols as keys, because the values are stored as properties. If you were using Object, it wouldn't be able to to distinguish key2 and key3 because their string representations would be the same:

var o = new Object();_x000D_
var key1 = 'key1';_x000D_
var key2 = {};_x000D_
var key3 = {};_x000D_

To add rows to existing DataTable in Dataset:

DataRow drPartMtl = DSPartMtl.Tables[0].NewRow();
drPartMtl["Group"] = "Group";
drPartMtl["BOMPart"] = "BOMPart";
DSPartMtl.Tables[0].Rows.Add(drPartMtl);

Theoretically, yes. Practice, not. Most kernels (incl. linux) doesn't allow you a second bind() to an already allocated port. It weren't a really big patch to make this allowed.

Conceptionally, we should differentiate between socket and port. Sockets are bidirectional communication endpoints, i.e. "things" where we can send and receive bytes. It is a conceptional thing, there is no such field in a packet header named "socket".

Port is an identifier which is capable to identify a socket. In case of the TCP, a port is a 16 bit integer, but there are other protocols as well (for example, on unix sockets, a "port" is essentially a string).

The main problem is the following: if an incoming packet arrives, the kernel can identify its socket by its destination port number. It is a most common way, but it is not the only possibility:

• Sockets can be identified by the destination IP of the incoming packets. This is the case, for example, if we have a server using two IPs simultanously. Then we can run, for example, different webservers on the same ports, but on the different IPs.
• Sockets can be identified by their source port and ip as well. This is the case in many load balancing configurations.

Because you are working on an application server, it will be able to do that.

As Niklas mentioned you can use the html2canvas library to take a screenshot using JS in the browser. I will extend his answer in this point by providing an example of taking a screenshot using this library ("Proof of Concept"):

function report() {
  let region = document.querySelector("body"); // whole screen
  html2canvas(region, {
    onrendered: function(canvas) {
      let pngUrl = canvas.toDataURL(); // png in dataURL format
      let img = document.querySelector(".screen");
      img.src = pngUrl; 

      // here you can allow user to set bug-region
      // and send it with 'pngUrl' to server
    },
  });
}

.container {
  margin-top: 10px;
  border: solid 1px black;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.4.1/html2canvas.min.js"></script>
<div>Screenshot tester</div>
<button onclick="report()">Take screenshot</button>

<div class="container">
  <img width="75%" class="screen">
</div>

In report() function in onrendered after getting image as data URI you can show it to the user and allow him to draw "bug region" by mouse and then send a screenshot and region coordinates to the server.

In this example async/await version was made: with nice makeScreenshot() function.

UPDATE

Simple example which allows you to take screenshot, select region, describe bug and send POST request (here jsfiddle) (the main function is report()).

async function report() {
    let screenshot = await makeScreenshot(); // png dataUrl
    let img = q(".screen");
    img.src = screenshot; 
    
    let c = q(".bug-container");
    c.classList.remove('hide')
        
    let box = await getBox();    
    c.classList.add('hide');

    send(screenshot,box); // sed post request  with bug image, region and description
    alert('To see POST requset with image go to: chrome console > network tab');
}

// ----- Helper functions

let q = s => document.querySelector(s); // query selector helper
window.report = report; // bind report be visible in fiddle html

async function  makeScreenshot(selector="body") 
{
  return new Promise((resolve, reject) => {  
    let node = document.querySelector(selector);
    
    html2canvas(node, { onrendered: (canvas) => {
        let pngUrl = canvas.toDataURL();      
        resolve(pngUrl);
    }});  
  });
}

async function getBox(box) {
  return new Promise((resolve, reject) => {
     let b = q(".bug");
     let r = q(".region");
     let scr = q(".screen");
     let send = q(".send");

         r.style.top    = (ey > 0 ? sy : sy+ey) +'px';
         r.style.width  = Math.abs(ex) +'px';
         r.style.height = Math.abs(ey) +'px'; 
     }
     
     
     
     //console.log({b,r, scr});

FragmentPagerAdapter is the factory of the fragments. To find a fragment based on its position if still in memory use this:

public Fragment findFragmentByPosition(int position) {
    FragmentPagerAdapter fragmentPagerAdapter = getFragmentPagerAdapter();
    return getSupportFragmentManager().findFragmentByTag(
            "android:switcher:" + getViewPager().getId() + ":"
                    + fragmentPagerAdapter.getItemId(position));
}

In my case I used sudo mkdir projectFolder to create folder. It was owned by root user and I was logged in using non root user.

So I changed the folder permission using command sudo chown mynonrootuser:mynonrootuser projectFolder and then it worked fine.

Use Case:

   Select Case When @PaidThisMonth < @OwedPast 
               Then @PaidThisMonth Else @OwedPast End PaidForPast

As Inline table valued UDF

CREATE FUNCTION Minimum
(@Param1 Integer, @Param2 Integer)
Returns Table As
Return(Select Case When @Param1 < @Param2 
                   Then @Param1 Else @Param2 End MinValue)

Usage:

Select MinValue as PaidforPast 
From dbo.Minimum(@PaidThisMonth, @OwedPast)

ADDENDUM: This is probably best for when addressing only two possible values, if there are more than two, consider Craig's answer using Values clause.

I managed to get a ZIP file or a PDF file by extending the StreamingOutput object. Here is some sample code:

@Path("PDF-file.pdf/")
@GET
@Produces({"application/pdf"})
public StreamingOutput getPDF() throws Exception {
    return new StreamingOutput() {
        public void write(OutputStream output) throws IOException, WebApplicationException {
            try {
                PDFGenerator generator = new PDFGenerator(getEntity());
                generator.generatePDF(output);
            } catch (Exception e) {
                throw new WebApplicationException(e);
            }
        }
    };
}

The PDFGenerator class (my own class for creating the PDF) takes the output stream from the write method and writes to that instead of a newly created output stream.

Don't know if it's the best way to do it, but it works.

you can use

moviesTitles.map((title) => Tab(text: title)).toList()

example:

    bottom: new TabBar(
      controller: _controller,
      isScrollable: true,
      tabs:
        moviesTitles.map((title) => Tab(text: title)).toList()
      ,
    ),

I already had index.html in the WebContent folder but it was not showing up , finally i added the following piece of code in my projects web.xml and it started showing up

  <servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping> 

select one.*, two.meal
from table1 as one
left join table2 as two
on (one.weddingtable = two.weddingtable and one.tableseat = two.tableseat)

Adding the primary key worked for me too !

Once that is done, here's how to update the data model without deleting it -

Right click on the edmx Entity designer page and 'Update Model from Database'.

Try

//*[text()='qwerty'] because . is your current element

To further iterate on Mik's answer, you could also recursivey attach a parent to all nested objects.

var myApp = {

    init: function() {
        for (var i in this) {
            if (typeof this[i] == 'object') {
                    this[i].init = this.init;
                    this[i].init();
                    this[i].parent = this;
            }
        }
        return this;
    },

    obj1: {
        obj2: {
            notify: function() {
                console.log(this.parent.parent.obj3.msg);
            }
        }
    },

    obj3: {
        msg: 'Hello'
    }

}.init();

myApp.obj1.obj2.notify();

I have on several projects.

The biggest difference in my opinion

• jQuery UI is fallback safe, it works correctly and looks good in old browsers, where Bootstrap is based on CSS3 which basically means GREAT in new browsers, not so great in old

• Update frequency: Bootstrap is getting some great big updates with awesome new features, but sadly they might break previous code, so you can't just install bootstrap and update when there is a new major release, it basically requires a lot of new coding

• jQuery UI is based on good html structure with transformations from JavaScript, while Bootstrap is based on visually and customizable inline structure. (calling a widget in JQUERY UI, defining it in Bootstrap)

So what to choose?

That always depends on the type of project you are working on. Is cool and fast looking widgets better, or are your users often using old browsers?

I always end up using both, so I can use the best of both worlds.

Here are the links to both frameworks, if you decide to use them.

1. jQuery UI
2. Bootstrap

If you are in Springboot please check the java version in the pom.xml file

<properties>
   <java.version>11</java.version>
</properties>

If this version doesn't match with your default version(Java) of the computer, that error can be happen.

Synchronized Method

Pros:

• Your IDE can indicate the synchronized methods.
• The syntax is more compact.
• Forces to split the synchronized blocks to separate methods.

Cons:

• Synchronizes to this and so makes it possible to outsiders to synchronize to it too.
• It is harder to move code outside the synchronized block.

Synchronized block

Pros:

• Allows using a private variable for the lock and so forcing the lock to stay inside the class.
• Synchronized blocks can be found by searching references to the variable.

Cons:

• The syntax is more complicated and so makes the code harder to read.

Personally I prefer using synchronized methods with classes focused only to the thing needing synchronization. Such class should be as small as possible and so it should be easy to review the synchronization. Others shouldn't need to care about synchronization.

The PostgreSQL manual indicates that this means the transaction is open (inside BEGIN) and idle. It's most likely a user connected using the monitor who is thinking or typing. I have plenty of those on my system, too.

If you're using Slony for replication, however, the Slony-I FAQ suggests idle in transaction may mean that the network connection was terminated abruptly. Check out the discussion in that FAQ for more details.

In my case settings.gradle contained invalid configuration.

I changed:

include ':app'
rootProject.name='<somthing else>'

To:

include ':app'

Error is gone. So maybe check your settings.gradle for potential errors. If this won't work try to remove cache and other tips.

The TEXTAREA element creates a multi-line text input control

The DateTimeFormatInfo class implements this interface, so it allows you to control the formatting of your DateTime strings.

just go to google docs and paste this as a formula, where URL is a link to your img

      =image("URL", 1)

afterwards, from google docs options, download for excel and you'll have your image on the cell EDIT Per comments, you dont need to keep the image URL alive that long, just long enough for the excel to download it. Then it will stay embedded on the file.

Here's a safe way for any iterable of delimiters, using regular expressions:

>>> import re
>>> delimiters = "a", "...", "(c)"
>>> example = "stackoverflow (c) is awesome... isn't it?"
>>> regexPattern = '|'.join(map(re.escape, delimiters))
>>> regexPattern
'a|\\.\\.\\.|\\(c\\)'
>>> re.split(regexPattern, example)
['st', 'ckoverflow ', ' is ', 'wesome', " isn't it?"]

re.escape allows to build the pattern automatically and have the delimiters escaped nicely.

Here's this solution as a function for your copy-pasting pleasure:

def split(delimiters, string, maxsplit=0):
    import re
    regexPattern = '|'.join(map(re.escape, delimiters))
    return re.split(regexPattern, string, maxsplit)

If you're going to split often using the same delimiters, compile your regular expression beforehand like described and use RegexObject.split.

If you'd like to leave the original delimiters in the string, you can change the regex to use a lookbehind assertion instead:

>>> import re
>>> delimiters = "a", "...", "(c)"
>>> example = "stackoverflow (c) is awesome... isn't it?"
>>> regexPattern = '|'.join('(?<={})'.format(re.escape(delim)) for delim in delimiters)
>>> regexPattern
'(?<=a)|(?<=\\.\\.\\.)|(?<=\\(c\\))'
>>> re.split(regexPattern, example)
['sta', 'ckoverflow (c)', ' is a', 'wesome...', " isn't it?"]

(replace ?<= with ?= to attach the delimiters to the righthand side, instead of left)

                                    ]
                                });
                            }
                        ]
                    }
                })
                 );

If the above solution didn't work for you, you can use import { withRouter } from 'react-router-dom';

Using this you can export your child class as -

class MyApp extends Component{
    // your code
}

export default withRouter(MyApp);

And your class with Router -

// your code
<Router>
      ...
      <Route path="/myapp" component={MyApp} />
      // or if you are sending additional fields
      <Route path="/myapp" component={() =><MyApp process={...} />} />
<Router>

Here's a tricky way to do this - select the cells that you want to replace and in Excel 2010 select F5 to bring up the "goto" box. Hit the "special" button. Select "blanks" - this should select all the cells that are blank. Enter NULL or whatever you want in the formula box and hit ctrl + enter to apply to all selected cells. Easy!

See some example in http://www.sitepoint.com/understanding-sql-joins-mysql-database/

You can use 'USING' instead of 'ON' as in the query

SELECT * FROM table1 LEFT JOIN table2 USING (id);

Use these:

webview.getSettings().setBuiltInZoomControls(true);
webview.getSettings().setDisplayZoomControls(false);

You can do it like this,

<input type="text" name="name" value="<?php echo $name;?>" />

But seen as you've taken it straight from user input, you want to sanitize it first so that nothing nasty is put into the output of your page.

<input type="text" name="name" value="<?php echo htmlspecialchars($name);?>" />

For me it was Design Patterns Explained it provided an 'Oh that's how it works' moment for me in regards to design patterns and has been very useful when teaching design patterns to others.

To collapse all use:

Ctrl + M and Ctrl+A
