Linux Output Display via Console RS232
In the office now being POC avocent for ACS products, which supposedly he can capture the output from linux. After reading read the documentation of the Linux-Serial finally found it, how to make Linux not just to the monitor output (VGA Card) but via RS232 Console (ttyS0).
1. Make sure your system support serial port.
[root@flubber root]# dmesg | grep tty
ttyS0 at 0x03f8 (irq = 4) is a 16550A
ttyS1 at 0x02f8 (irq = 3) is a 16550A
ttyS0 at 0x03f8 (irq = 4) is a 16550A
ttyS1 at 0x02f8 (irq = 3) is a 16550A
[root@flubber root]# setserial -g /dev/ttyS[01]
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3
Remove MySQL Binary Log Files Eating Lots of Disk Space
By default, MySQL 5.0 and above enables MySQL Binary Log. Keeping MySQL Binary Log might take up a lot of disk space for long run. Older MySQL Binary log can be removed in order to keep your hard disk space free.
MySQL Binary Log stores query event such as add, delete and update in a very details way. The Binary Log is used for two main purposes;
* 1. Replication between master and slave server, statement that has been made on Master server will later send it to slave server.
* 2. Recovery, certain recovery job required data stored in MySQL Binary Log.

Adding nodes to a GPFS cluster using use command mmaddnode, mmlsnode and mmlscluster.
You can add nodes to an existing GPFS cluster by issuing the mmaddnode command. The new nodes are available immediately after the successful completion of this command.
You must follow these rules when adding nodes to a GPFS cluster:
* You may issue the command only from a node that already belongs to the GPFS cluster.
* A node may belong to only one GPFS cluster at a time.
* The nodes must be available for the command to be successful. If any of the nodes listed are not available when the command is issued, a message listing those nodes is displayed. You must correct the problem on each node and reissue the command to add those nodes.
You can use command mmaddnode, mmlsnode and mmlscluster.

Menangislah…
Menangislah Untuk Ramadhan Yang Kan Hilang Nak, menangislah…
Jika itu bisa melapangkan gundah yang mengganjal sanubarimu.
Jika itu adalah ungkapan penyesalanmu.
Bahwa Ramadhan sudah bergegas di akhir hitungan.
Tapi baru merupakan awal tekadmu untuk menyempurnakan tarawih dan qiyamul lailmu yang centang perenang
Menangislah,
Allah tak menjanjikan apa-apa untuk Ramadhan tahun depan,apakah kamu masih disertakan; sedangkan Ramadhan sekarang cuma tersisa beberapa belas. Tak ada yang dapat menjamin usiamu sampai untuk Ramadhan besok, sedang Ramadhan ini tersia-siakan.
Menangislah untuk Ramadhan yang kan hilang.
Biar butir bening itu jadi saksi di yaumil akhir.
Menangislah, lebih keras…
Untuk dosa-dosa yang belum diampuni, tapi kamu masih juga menambahi dengan dosa baru. Berapa kali kamu sholat taubat, tetapi tak lama kemudian ada saja kelalaian yang kamu buat?
Menangislah………
Tuntaskan semuanya mulai malam ini. Karena besok waktu akan bergerak makin cepat, Ramadhan semakin berlari.
Tarawih, sedekah, tilawah Qur’an, qiyamul lail, i’tikaf.
Tahu-tahu sudah sepuluh hari terakhir dan kamu masih juga belum siap.
Sekarang, atau mungkin tidak ada sama sekali…
