Generasi terbaru internet wireless telah tiba di seantero Hong Kong. Long Term Evolution (LTE) demikian teknologi baru ini dikenal menjanjikan akses internet lebih memuaskan bagi penduduk di negara tersebut.

Jaringan LTE itu disebut-sebut akan memberikan kecepatan sangat tinggi di seluruh Hong Kong. Media setempat bahkan mempromosikan LTE di Hong Kong akan memungkinkan pengguna menonton streaming film atau event olahraga live di jalan bahkan di atas bukit dengan kualitas jaringan sangat baik dan gambar sangat jernih.

Dikutip detikINET dari AFP, Sabtu (27/11/2010), jaringan internet generasi keempat itu digelar oleh operator mobile Hong Kong bernama CSL bekerjasama dengan pembuat perlengkapan telekomunikasi ZTE Corporation.

"Peluncuran perdana jaringan LTE di Asia ini benar-benar bersejarah," kata Joseph O'Konek selaku Chief Executive CSL.

Dikatakan olehnya, bagi sebagian besar orang ini akan menjadi pengalaman pertama mereka dalam internet. Mereka berada pada keuntungan besar dari generasi internet sebelumnya karena LTE melompati semua teknologi fix line.

Leading Geeks

Almost 4 years for me working on Kalla Group, one of the most multi business company in Indonesia. I'm leading 2 staffs at 2007 and now grown to be 10 staffs, dividing in 2 section.
If other workers , the connection between leader and the followers are clear, then in IT Managerial it's come to see in other way. Another department will be leading by orthodox rules "Knowledge is a Power" then in Geek way, i'm using "Understand Is A Power".
Handling a geeks, and their Geekwork is a must, is a delicate arts. This article is a foreword for a coming soon IT Managerial article that will be publish in this blog. Soon


Clonezilla, Opensource "Ghost" Way

You're probably familiar with the popular proprietary commercial package Norton Ghost®. The problem with these kind of software packages is that it takes a lot of time to massively clone systems to many computers. You've probably also heard of Symantec's solution to this problem, Symantec Ghost Corporate Edition® with multicasting. Well, now there is an OpenSource clone system (OCS) solution called Clonezilla with unicasting and multicasting!

Clonezilla, based on DRBL, Partclone and udpcast, allows you to do bare metal backup and recovery. Two types of Clonezilla are available, Clonezilla live and Clonezilla SE (server edition). Clonezilla live is suitable for single machine backup and restore. While Clonezilla SE is for massive deployment, it can clone many (40 plus!) computers simultaneously. Clonezilla saves and restores only used blocks in the harddisk. This increases the clone efficiency. At the NCHC's Classroom C, Clonezilla SE was used to clone 41 computers simultaneously. It took only about 10 minutes to clone a 5.6 GBytes system image to all 41 computers via multicasting!

Resetting your Mysql Root Account (Linux)

Have you ever forgotten the root password on one of your MySQL servers? No? Well maybe I’m not as perfect as you. This is a quick h00tow (how to) reset your MySQL root password. It does require root access on your server.

First things first. Log in as root and stop the mysql daemon. Now lets start up the mysql daemon and skip the grant tables which store the passwords.

mysqld_safe --skip-grant-tables

You should see mysqld start up successfully. If not, well you have bigger issues. Now you should be able to connect to mysql without a password.

mysql --user=root mysql

update user set Password=PASSWORD('new-password') where user='root';
flush privileges;
exit;

Now kill your running mysqld, then restart it normally. You should be good to go. Try not to forget your password again.
