Open Source Software for Windows ?
Ya.. memang ada software open source for windows, jadi bagi anda yang masih nekad menggunakan windows b@*@*@* atau original (aka. berlisensi) anda bisa menggunakan aplikasi aplikasi yang di download dari http://www.opensourcewindows.org.
Mereka menjanjikan aplikasi-aplikasinya adalah Open Source dan berjalan tanpa embel embel virus adware, spyware dan ware ware yang lain..( tapi anda tetap harus aware jika pakai window$ )
Berikut daftar kategori aplikasi yang ada dan bisa di download :
– Web Browsing
– Video Player / Video Podcasting
– IM – Instant Messaging
– Email
– RSS
– Peer-to-Peer Filesharing
– Video Playback
– DVD Ripping / Video Conversion
– Word Processing / Office Suites
– Podcasting
– DVD Ripping
– Sound Recording
– Graphics / Photo Editing
– Graphics editor with a very nice interface.
– Vector graphics application.
– FTP / SFTP
– IRC
Bermain-main dengan btrfs dengan Linux Mint 13
Setelah membaca-baca sedikit tentang btrfs, gw putuskan untuk langsung mencoba btrfs. Secara default, Linux Mint 13 belum support btrfs. Gw harus menambahkan tools, btrfs-tools. Tools ini akan digunakan untuk melakukan konversi file system dari ext3 yang selama ini gw pakai menjadi btrfs.
Secara umum btrfs menawarkan sejumlah kelebihan dibandingkan filesystem linux yang lain. Hanya saja, btrfs belum dinyatakan stabil dan tidak disarankan untuk digunakan untuk production system.
————————————-
Btrfs is a new copy on write filesystem for Linux aimed at implementing advanced features while focusing on fault tolerance, repair and easy administration. Initially developed by Oracle, Btrfs is licensed under the GPL.
Note that Btrfs does not yet have a fsck tool that can fix errors. While Btrfs is stable on a stable machine, it is currently possible to corrupt a filesystem irrecoverably if your machine crashes or loses power on disks that don’t handle flush requests correctly. This will be fixed when the fsck tool is ready.
Features
Linux has a wealth of filesystems to choose from, but we are facing a number of challenges with scaling to the large storage subsystems that are becoming common in today’s data centers. Filesystems need to scale in their ability to address and manage large storage, and also in their ability to detect, repair and tolerate errors in the data stored on disk.
The main Btrfs features available at the moment include:
- Extent based file storage
- 2^64 byte == 16 EiB maximum file size
- Space-efficient packing of small files
- Space-efficient indexed directories
- Dynamic inode allocation
- Writable snapshots, read-only snapshots
- Subvolumes (separate internal filesystem roots)
- Checksums on data and metadata
- Compression (gzip and LZO)
- Integrated multiple device support
-
- RAID-0, RAID-1 and RAID-10 implementations
- Efficient incremental backup
- Background scrub process for finding and fixing errors on files with redundant copies
- Online filesystem defragmentation
Additional features in development, or planned, include:
- RAID-5 and RAID-6
- Object-level mirroring and striping
- Alternative checksum algorithms
- Online filesystem check
- Efficient incremental filesystem mirroring
————————————-
Setelah instalasi btrfs-tools, gw buka terminal :
1. Unmount file system yang akan di-convert.
$sudo umount /backup
2. Lakukan konversi
$sudo btrfs-convert /dev/sda7
3. Setelah selesai konversi, lakukan check UUID untuk filesystem baru (karena Linux Mint menggunakan informasi blkid suatu partisi untuk melakukan mounting di /etc/fstab). Bisa juga menggunakan info seperti /dev/sdax, like oldis style.
$sudo blkid /dev/sda7
4. Edit file /etc/fstab untuk mengubah informasi filesystem dan blkid yang baru saja didapatkan.
5. Aktifkan juga algoritma kompresi untuk filesystem btrfs. Bisa zlib, bisa juga lzo.
Selamat mencoba !!
Building a Samba 4 Active Directory Domain
In this Article, i will outline the configuration of a small Active Directory using Samba4.
The Ubuntu versions involved is 12.04. I assume that you have modest knowledge on how to configure Ubuntu on the command line – i.e. i will not explain every single step in detail.
Network parameters we will use are:
Network name:demo.local
IP Range:192.168.99.0/24
Base System and Samba 4
Step 1: Install a Ubuntu 12.04 System
Step 2: Configure the Network to use a static address. Edit /etc/network/interfaces:

auto lo eth0 iface lo inet loopback iface eth0 inet static address 192.168.99.200 netmask 255.255.255.0 gateway 192.168.99.254 dns-nameservers 192.168.99.200 192.168.99.254 dns-search demo.local |
Step 3: Add the basic host entries to resolve without DNS
Edit /etc/hosts and insert:

127.0.0.1 localhost 192.168.99.200 vupapsam401 vupapsam401.demo.local |
Step 4: Install the Samba 4 Packages
Basis guy, please get ready to welcome SAPGUI for Windows 7.30
Sebentar lagi (akhir Juni 2012), SAPGUI for Windows terbaru, versi 7.30 akan hadir di tengah-tengah kita. SAPGUI for Windows versi 7.20 masih akan disupport sampai akhir April 2013. Beberapa improvement telah dibuat untuk SAPGUI terbaru ini.
Berikut beberapa improvement yang akan diperlihatkan di SAPGUI versi 7.30, sebagai berikut :
SAP GUI for Windows 7.30 is expected to be shipped on 29th of June 2012. The new release is the successor to release 7.20 and offers several improvements in various areas:
- New CORBU design (successor of Signature)
- Support for color schemes in SAP Signature Design (changing the color scheme per system and even per client)
- Branding – customers can add a logo in the title bar of SAP Signature design / Corbu Design
- Customizable tab order (users / administrators can change the tab sequence on application screens)
- Floating docking containers (docking containers can be moved as preferred by the user – these settings are persisted)
- Comments for connection entries in SAP Logon
- Indication of security status: Once a connection to an SAP System has been established SAP GUI shows whether the connection is secure or not (indicated by a lock icon in the SAP GUI status bar).
- Usability improvements for the security configuration in SAP GUI options dialog (larger size, search, filter) – a tool for the administrator that allows to create the security rulesets will likely follow in a later release
- Customizable permissions in the SAP GUI options dialog: An administrator can define which sections / values can be changed by the users and which ones cannot.
