export LC_ALL=C # or export LC_ALL= "en_US.UTF-8" |
either in the console (for current session) or in .bashrc file.
After that you should be ready to go with:

Look at the file apache-activemq-5.9.1/conf/jetty-realm.properties
.
The format is: username: password, rolename
. The default values are: admin:admin,admin
. Therefore, changing the second value will update the password. admin: newpassword, admin
.
This is very much easier and straight forward as below:

var jsonString = "{\"key\":\"value\"}" ; var jsonObj = JSON.parse(jsonString); console.log(jsonObj.key); |
As you can see, we are using the built-in global JSON Object to parse a string which has JSON Data. Also, it might be good idea to use “.trim()” method on the string, if you think there might be some chance of extra space etc in the JSON string. Otherwise, it won’t get parsed and you will face an unexpected error.

XMLHttpRequest cannot load http://ajax.example.com/like/. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://blog.example.com' is therefore not allowed access.
—
Solution:
Set htaccess like this:
# Always set these headers.
Header always setAccess-Control-Allow-Origin"*"
Header always setAccess-Control-Allow-Methods"POST, GET, OPTIONS, DELETE, PUT"
Header always setAccess-Control-Max-Age"1000"
Header always setAccess-Control-Allow-Headers"x-requested-with, Content-Type, origin, authorization, accept, client-security-token"

ini sample jika server kita mengalami kehabisan memory dan bisa di akalin dengan cara seperti ini ..
First:
git clone https://github.com/phalcon/phalcon-devtools.git
Install composer in a common location or in your project:
curl -s http://getcomposer.org/installer | php
Create the composer.json file as follows:
{
"require": {
"phalcon/devtools": "dev-master"
}
}
If you are still using Phalcon 1.3.x, create a composer.json with the following instead:
{
"require": {
"phalcon/devtools": "1.3.*@dev"
}
}
Run the composer installer:
php composer.phar install
Create a symbolic link to the phalcon.php script:
ln -s ~/devtools/phalcon.php /usr/bin/phalcon
chmod ugo+x /usr/bin/phalcon
To list users:
select user,host from mysql.user;
To show privileges:
show grants for 'user'@'host';
To change privileges, first revoke. Such as:
revoke all privileges on *.* from 'user'@'host';
Then grant the appropriate privileges as desired:
grant SELECT,INSERT,UPDATE,DELETE ON `db`.* TO 'user'@'host';
Table:
GRANTALTER,CREATEON example TO'someuser'@'somehost'
Finally, flush:
flush privileges;
The MySQL documentation is excellent:

Selain kemampuannya untuk memetakan tabel dalam database relasional, Phalcon dapat memetakan dokumen dari database NoSQL. ODM menawarkan fungsi CRUD, peristiwa, validasi antara layanan lainnya.
Karena tidak adanya query SQL dan perencana, database NoSQL dapat melihat perbaikan nyata dalam kinerja menggunakan pendekatan Phalcon. Selain itu, tidak ada bangunan SQL mengurangi kemungkinan suntikan SQL.
