OS: Ubuntu 9.10

Specs: Lenovo Y41 (Centrino Duo, Intel Integrated GPU)

Enable Display Settings in Tray

Go to Sistem -> Preferensi -> Tampilan

(System -> Preferences -> Display, cmmiw)

Then mark the check list for “Perlihatkan tampilan di panel” and press “Terapkan” (“Apply”).

Check list

After you do that, there would be an icon in the tray:

Tray icon

You can close the Tampilan (Display Preference) now because

Everytime You Plug A Monitor/Projector Into Your Laptop

Just click on the tray icon, choose'”Configure Display Settings…”  and it will automatically detect your monitor and adjusting your display.

So,

Can you have simpler way than this?

Dual Screen Configuration

Dual Screen Configuration

Due to my lazyness of backup and the way I formatted my computer, I posted my Xorg configuration. This is not necessary using Ubuntu because the XRandr extension (and its workaround) have been fully supported. Unfortunately, I’m using KDE4 in my desktop, so I must configure the Xorg to get my dual screen.

My configuration is using ATi X550, one monitor plugged into VGA and another one via DVI converter. Each has 1280×1024 and the VGA is in the left side of my DVI monitor. So, without further censorship, here’s my

/etc/X11/xorg.conf

:

Syncing My Home (Laptop and Desktop)

Syncing My Home (Laptop and Desktop)

Ever since becoming graduate student, I am in constant despair of syncing my work and study. Luckily, my sister now employed in one of the public accounting and she was promised to have her own (working) laptop. Because of that, I can use my laptop freely and working mobile. It helps a lot and I can work while study and study while working. Thanks to RMS, now I’m in my spirit again to hack into a new system, which I won’t tell yet. [Takut sesumbar :-P]

To have work continuity, I need to sync my home in my laptop and desktop computer. I have three candidates:

  1. A script from Pak Ibam,
    sedot
    built especially for syncing home.
  2. Ripping
    sedot-ng
    script from Kambing.
  3. Using
    unison
    .

The #1 script is powerful, but it was designed to syncing into a USB disk and it need some tweak because I have gigs of data in my home. Obviously, #2 is overkill. I don’t need my syncing in plurk and automate. Solution  #3 needed to be learned because we are used to use

rsync

than that. To make it short, I go with solution #3 because it has a Debian package and have a GUI.

Unison have a powerful option to cope with my need, syncing both place. I can work in my desktop or laptop and get both of them sync each other. Okay, before you get bored, like I do. Let’s try to install it.

#0 Connect your desktop and laptop

A pre condition, your laptop and your desktop is connected and having SSH server installed. In my example, because I’m syncing from laptop, you just need to install the SSH server into your desktop. Every GNU/Linux system by default is installed with SSH client.

In desktop (and optionally on laptop), install SSH:

$ apt-get install ssh

#1 Install unison

In laptop:

$ sudo apt-get install unison-gtk

In desktop:

$ sudo apt-get install unison

Why I install GUI-based in laptop? Well, I synced the data from my laptop and treated my desktop as a server. Another reason is because my desktop using KDE and my laptop using Gnome. Unison is located in

Aplikasi -> Aksesoris -> Unison

#2 Setup A Profile

Profile is a jargon used by unison to a configuration file. You can have many configuration files, each doing specific job.

When first greeted, enter the base (unison use “root” term) directory of which you would like to sync against. I entered my home directory (e.g. “/home/user”).

base directory

Press OK and then choose your remote computer, in my case, the desktop’s home directory. If you are funky like me, using non-standard SSH port, select Socket first and then put your non-standard SSH. [NOTE: This step is unecessary for most people]

Socket

And don’t forget to select SSH again. Fill the remote Directory and the remote’s Host IP number, before press OK. Here’s the screenshot:

SSH

After OK, you are asked of your remote host password. Then you are ready to go.

Password asked

Honestly, I’m cheated a bit about unison. Usually, people creates a special directory like “/home/user/SYNCED” and put all the synced contents into that directory. I put my home directory, which contain gigs of files which making the unison a little bit lame at initial. So, I close the unison and starts to edit configuration manually to have only few directories that needed to directory.

$ gedit .unison/default.prf

Here’s my (EDITED) default configuration:

# Unison preferences file
root = /home/user
root = ssh://user@192.168.1.2//home/user
# Path to synchronize
path = Project
path = Library
path = Dokumen
path = .subversion
path = .purple
path = Musik
path = Gambar
path = Backup
path = Video
path = .netbeans
ignore = Name .directory

As you can see, I only put some of the directory in home. I’m using Bahasa Indonesia as my default installation. KDE4 uses “.directory” directory to keep its meta data. So, I need to exclude that directory. And, uhm… psst… I logged all of my conversations. 😀

#3 Syncing…

Just press GO and you’re done.

unison GTK

 #4 MAKAN2x ™

MAKAN2x ™ [This is a trashing section :D]

#5 Just In Case…

you are overwhelmed and don’t want to go all of those step, just do #0 and #1 then copy my configuration to your own “

.unison/default.prf

” and edit as you like. That’s faster. 😀

Some Compile Glitches

Some Compile Glitches

If you are using 9.10 like mine, there are few things that applications need to adapt.

1 G++ 4.4 will not include stdio automatically anymore

If you have these kind of error:

error: 'stdout' was not declared in this scope
error: 'fprintf' was not declared in this scope
error: 'fclose' was not declared in this scope
... and so on.

The fix is to include cstdio, meaning:

#include <cstdio> 

2 Unharmful warning message from CMake

CMake now wants the application set the minimum CMake version. Add this:

cmake_minimum_required(VERSION 2.6)
Driver for U.r.U 4500 in Kernel 2.6.31

Driver for U.r.U 4500 in Kernel 2.6.31

I was having trouble with using kernel 2.6.21 that get supported by default UrU kernel, the X server refused to run. So, in my despair, I view some LKML threads, patch here and there: Voila! I got a working  Kernel driver for U.r.U fingerprint for Linux kernel 2.6.31. [NOTE: Remove the .pdf extension.]This patched driver has been working in Debian’s 2.6.31-trunk and Ubuntu Karmic, my fave distro at the momen. The installation is simple and described here.For the sake of KISS, I will try to cover it for you.

$ mv dpfp-2.6.31.tar.gz.pdf dpfp-2.6.31.tar.gz
$ tar xvfz dpfp-2.6.31.tar.gz
$ cd source
$ make

And then install it to your kernel:


$ sudo mkdir /lib/modules/`uname -r`/kernel/drivers/biometric
$ sudo cp mod_usbdpfp.ko /lib/modules/`uname -r`/kernel/drivers/biometric/
$ sudo depmod -aq

Then you can abuse it the way you feel. This kernel has been tested worked on UrU 4500 and UrU4000B.

Getting Juicy Sound From Your Ubuntu

Getting Juicy Sound From Your Ubuntu

Personally, I want to post a rant about current Indonesian Cabinet, but then I realize that this blog is not that personal (although the disclaimer said so…). Besides, I’m taking space from Universitas Indonesia, it would be not nice for them. So, to take away my anger, I will put a constructive post.

1 Selecting a good sound driver

If you are like mine (Intel ICH compatible onboard sound), which likely so, the following driver really for you. I don’t know about other sound cards, but I think by the way people congratulate the driver, I guess it really enhanced them. Gosh, I forgot to mention what is the name of the sound driver, it’s OSS4 developed by 4Front.

A warning, mind you, this driver is currently unsupported, it’s not in mainline anymore. Since the OSS 3.8 in 10+ years ago, the OSS4 development goes behind walls and just recently release their driver again as GPL code. This driver will be supported by KDE 4 in 4.4 release, which is next year. Fortunately for Ubuntu user, they have a GStreamer plugin. But, for me, and the rest of Kubuntu users, we will stick on the native

ossxmix

mixer application (which fortunately written on Qt4).

How to install it? Well, duplication is unnecessary, just go into here and go to the detail. It is maintained by community.

As for me, the way I’m installing it is this way:

$ sudo apt-get install kernel-package

I’m using an exotic way of installing it from 4Front’s mercurial (yet another DVCS just like GIT). But, you can get the snapshot here. Sane people, just download the deb package from here.

Now, how do I do it? (with modified version where we just download the snapshot, not using mercurial)

$ tar xvfj oss-v4.2-build2000-src-gpl.tar.bz2
$ mkdir build && cd build$ ../oss/configure --config-midi=YES --config-vmix=FLOAT --enable-timings --enable-libsalsa=NO
$ make && sudo make deb
$ sudo dpkg -i oss-linux-4.2-2000_i386.deb
Of course, the sane way is, you download the package and just install the package. Now, configure your Ubuntu sound to use only OSS:
$ sudo dpkg-reconfigure linux-sound-base

And choose OSS. Here’s a bonus screenshot:

OSS4 on linux sound base

Now, up until this point, we are finish. Just restart your computer, like I would after posting this post (hey, running live example does justified your post  😛 ).

For information on configuring applications, just look at here. It’s just a detail info about changing all sound I/O to use oss, which most program support.

2 Choosing A Good Music Player

Unfortunately, XMMS is already deprecated and its dependency, GTK+1, might be removed soon from Ubuntu repository. But, go here if you dare, it’s a little repository specially dedicated for XMMS. Why is this 10+ years old software still in mention? Well, you can call me old school, but I do grew up with it. Not because of sentimental reason, but for one good reason:

Modern music player is crap!

They don’t have equalizer (XMMS has 32 channel equalizer plugins) and they don’t have sound effects. Winamp has Dee3, but it’s also being deprecated. They only hogging resources with good looks (which unfortunately I don’t need). Do I stare at the player all the time? Heck, no! I’m using it in the background and even put it on the systray.

Luckily, we have Audacious2. It saves some good plugins for us. Just install it:

$ sudo apt-get install audacious audacious-dev

The

-dev

is to install a must have plugin. Go to here and download Freeverb3 plugins. I choose the 2.4.0-rc2, anything will do. Oh, don’t forget to install fftw3, Fast Fourier Tra…, nevermind you won’t bother what is that… 😛 Just:

$ sudo apt-get install libgtk2.0-dev libfftw3-dev

Now, let’s kill time:

$ tar xvfz freeverb3-2.4.0rc2.tar.gz$ cd freeverb3-2.4.0
$ ./configure --enable-ldouble --enable-audacious --enable-sse2  --enable-srcnewcoeffs --enable-plugdouble --prefix=/usr
$ make && sudo make install

You can substitute

make install

with

checkinstall

, but that’s beyond the scope of this rant-replacement post. If nothing goes wrong, you can see like this:

Audacious2 + Freeverb3

I’m selecting the Freeverb3 stereo enhancer and the crystalizer plugin. Btw, you can see my Audacious equalizer, it was for my PX100 headphone, but I’ve tested it on HD280 Pro. The bass may need some tweaking with PX200. Anything else, vary.

For An Ending

If you just don’t have that sensitive for sound like I do, just install audacious and you are fine. I’m ripping all of my CDs to FLAC and OGG. That’s why I need the sound quality as what I am paying to have and I want to have it in a reasonable cost (gratis!). Hopefully, modern player could learn to provide basic functionalities first than feature.

Hello Ubuntu

Hello Ubuntu

 Scary!

Yeah, scary! It’s been 5 years since Warty and I’ve been there! I’ve been there since Ubuntu was still a derivative work of GNU/Linux Debian. I’ve been there when we can have Ubuntu repository compatible with Debian, even mixed them around. It’s been that long but feels like yesterday. The way Mark shunned us with the possible way of enhancing community as a strength. The revolutionary thinking at that time to introduce Free Software and Open Source Software as a brand of open community-driven.

Open, because it was targeted to non-techie people also. Open, because it has code of conduct. Open, because it would not scare people by RTFM-ing them. Open, because it’s an enterprise product that will stay free forever.

Feels like it was yesterday that the fat Dapper haunted my labs. Now, we have a professional GNU/Linux distro and getting better every release. This making me looking forward for Karmic Koala.

PS: Kambing now have stable repository, happy upgrading!

PPS: I’m running the current Kubuntu Karmic Koala and it’s fascinatingly fast and stable. Good work, Ubuntu!

Ubuntu di Tangan Pengguna

Ubuntu di Tangan Pengguna


Beberapa orang sudah berpindah dari beberapa versi distro sebelumnya ke K/Ubuntu karmic. Saya bisa bilang, saya juga termasuk di dalamnya. Selain tergoda dengan inovasi XSplashnya, saya juga ingin mengetahui apa yang menjadi perbedaan distro ini dengan yang lainnya. Lagipula, hitung-hitung menunggu Debian Experimental kembali stabil. Ah, cukuplah basa-basi!

Ada 2 komputer saya yang saya ubah:

  • Laptop di rumah dengan menggunakan Ubuntu Karmic

  • Komputer kantor dengan menggunakan Kubuntu Karmic

1 Penambahan modem manager

Ini menjelaskan mengapa saya tidak bisa terhubung ke Internet dengan menggunakan /etc/network/interfaces saya, baik di Debian mau pun Ubuntu. Setidaknya sudah sebulan saya mengonfigurasi Debian saya dengan menggunakan ifconfig dan route.(Wew, perjalanan ke masa dahulu kala!)

Setidaknya Karmic benar-benar menempatkan dirinya untuk pengguna GUI. Totally for n00b!  😀

Konfigurasi IM2 dengan menggunakan laptop di rumah berlangsung dengan mudah. Kini saya sudah tidak perlu menggunakan program wvdial untuk terhubung ke Internet. Tapi, koneksi di kantor cukup merepotkan, saya harus login dulu agar Network Manager bisa mengaktifkan IP saya. Ya, ber…

2 Boot-related

Ya, berhubung saya juga tidak mau dibilang makhluk dari jaman pre-historik (yang demen maenan konsol sampe bunyi). Saya mengikuti saja perkembangan zaman evolusi antarmuka.

XSplash benar-benar membuat tampilan Ubuntu tambah cantik, walau pun masih kalah dengan rhgb dan plymouth milik distro-distro lain. Karena masih dalam proses pencarian jati diri, saya maklum saja. Apalagi, XSplash ini didaulat akan stabil pada Lucid Lynx.

Kalahnya dalam hal apa?

Proses Ubuntu di laptop saya menjadi lebih lama. Proses masuk dari GDM ke desktop lebih lama. Tentu saja, beda lamanya hanya hitungan detik. Tapi, saya yang telah termanjakan dengan waktu booting yang cepat di 8.10, sudah tidak terbiasa menunggu beberapa detik lagi….  😎

Tampilan antara dari proses pemilihan sistem operasi di GRUB ke XSplash masih menyempatkan tampilan teks-teks prehistorik yang (katanya) dapat menakutkan n00b, ahem, pengguna baru dan (katanya lagi, lho) terlihat kurang profesional. Yah, namanya masih baru.

Kubuntu saya lebih parah, XSplash tidak ada, yang ada hanya usplash dengan tampilan kuno ala < 7.04 yang segera saya buang. Menurut [KKX], Kubuntu mau menggunakan Ksplashx, komponen asli dari KDE untuk splash screen (ini bahasa Indonesianya apa, yah?), yang dimulai sebelum masuk ke dalam KDM. Tapi sebelum itu terjadi, kita harus menikmati tampilan teks prehistorik dan proses booting yang di bawah 10 detik (setidaknya di komputer saya).

3 Distro-specific support

Walau pun Debian adalah ompung dari Ubuntu, saya kecewa melihat dukungan terhadap Debian masih kalah dibandingkan dengan Ubuntu. Sungguh, adanya repositori PPA adalah ide brilian yang lebih dibandingkan cabang experimental pada Debian. Setiap pengembang Ubuntu dapat menyertakan paket-paket individual lebih cepat. Saya dapat tersuguhi dengan Chromium versi SVN. Bisa menatarnya setiap hari ke versi terbaru tanpa mengompailnya lebih dahulu. Sayangnya Project Neon hanya menyediakan versi Ubuntu stabil.

Saya belum menemukan E17 di Ubuntu karena masih puas dengan kinerja Kubuntu yang stabil. Netbeans ada di repositori Ubuntu dan lumayan tertatar.

Tapi, ompung Debian masih menang di manajemen proses. Ketika saya hendak menyalaulangkan KDM, skrip upstart gagal melakukannya sehingga saya harus menggunakan cara prehistorik (“

sudo kill -9 Xorg

“). Aplikasi Apport (application report) juga menyebalkan, saya masuk ke Kubuntu dan diberikan beberapa peringatan tentang rusaknya aplikasi. Untuk mematikan Apport, silahkan ubah berkas

/etc/default/apport

dan ubah

enabled=1

menjadi

enabled=0

Maaf, saya tidak tahu cara selain cara prehistorik…

4 Kubuntu-specific

Anggapan Kubuntu anak haram adalah tidak benar, setidaknya ia adalah anak yang kurang diperhatikan. Mungkin memang dukungan upstream sendiri yang kurang terhadap fitur penting seperti Proxy dan tampilan Multihead. Teman saya yang menggunakan Ubuntu dapat langsung saja mengaktifkan kedua monitornya yang terhubung ke ATi X550 (satu ke VGA, satu ke DVI) dan mendapatkan Multihead. Sedangkan saya harus menggunakan zaman prehistorik dengan membuat xorg.conf dan memodifikasinya untuk Multihead.

Tapi, saya senang dengan Project Ayatana yang menyediakan sebuah applet kecil mengikuti tema KDE sehingga notifikasi lebih terintegrasi dibandingkan Ubuntu.

Hmm… sudah jam 8 kurang. Saatnya kembali ke pekerjaan. Maaf tidak ada skrinsut, laptop di rumah dan komputer kantor saya dua monitor. Percuma diskrinsut kalau tidak memakai kamera. Selain bot dan spam, silahkan berkomentar.

Screwed Repository

Screwed Repository

If you have been using our Ubuntu repository (Kambing), you would have package failure. This was because in the few days, all of Ubuntu repository was having an invalid packages.gz file. The matter has been resolved upstream and now we are synchronizing with main Ubuntu repository. Please wait a moment until we have our site updated. Btw, I’m using Kubuntu Karmic and one simple line to describe it:

IT ROCKS!

One glitch, though, if you have an ATi card like mind, don’t upgrade you MESA into libgl1-mesa-dev_7.6.0-1ubuntu2. It appears a regression has made this card unusable. Other than that, watch out that drool! 😀

What Free/Open Source Can Do

What Free/Open Source Can Do

[DISCLAIMER: This is a long post of my private study in technology, that’s why I cover it with –MORE– tag.]

For you folks who’s been following my facebook status (like there would be one :P), you would realized that recently I’m in a state of confusion of whether to buy iPhone 3GS, HTC Heroes, and Beagle Board. No, I’m not a rich man, just a serious hacker (you do know the difference between hacker and cracker) and being serious in FOSS since long.

You may asked me why am I willing to flush my savings for those kind of stuff?

Installing Ubuntu Karmic Via Debootstrap

Installing Ubuntu Karmic Via Debootstrap

This is just an intermezzo post, just a fun stuff to do. I woke early this morning and couldn’t went to sleep again. So, I fired up my PC and checked things up. Well, I’m using GNU/Linux Debian Unstable/Experimental. It appears the Experimental is waiting for KDE 4.3.2 and Xorg 7.5. Debian also had MESA 7.6 landed on Experimental recently.

Hmm.. another major Xorg change and another ABI to break (hey, I guess that’s why they called that Experimental branch). FYI, current MESA implementation (7.6) had a feature to tell the application about the unsupported OpenGL 1.3 extension that makes my (un)happy KDE 4.3.1 crashed. So, in these few days I decided to move out to another distro.

I got an interesting story from Karmic development. It appears that this upcoming Ubuntu release will be pushing its X11 server in front just for the sake of bootsplash. Oh, it’s called XSplash and according to the original goal, it would be stable at Karmic+1. But, heck, those FOSS guys always calling something that runs well as experimental (e.g. Beryl/Compiz). So, why wait?

So, to do this I do:

$ sudo mkdir /tmp/test$ sudo mount /dev/sda1 /tmp/test

$ cd /tmp/test/

$ sudo debootstrap karmic . http://kambing.ui.ac.id/ubuntu/

View some profiles at Facebook and Komunitas @ UI, and write this entry. After this finish, for the following commands, I cheat a bit. I just found out that Kambing was in process of syncing its file, so I add dl2.foss-id.web.id to my source package (copy the entry and change the server from kambing to dl2 in the copied entry) and add

50Proxy

script to my

/etc/apt/apt.conf.d

for using proxy. I think by the time you read this, Kambing (maybe) already done syncing its files.

The best thing using experimental thingie, I don’t need to mount any of kernel filesystem. Usually, to install Grub, you would mount some stuff and creating special device in

/dev

in order for it to get system information. In my Debian system, I’m using GRUB2 and it actually have a nifty tool called

grub-probe

that probes any OS and kernels. So, this is what I do next:

$ sudo chroot /mnt/test# dpkg-reconfigure locales

locale-gen id_ID.UTF8

Hey, I’m always using Indonesian translation. That’s the strength of FOSS, they respect other language than English.

Anyway, then I installed the Ubuntu desktop

# apt-get install ubuntu-desktop

It would have:

0 upgraded, 1045 newly installed, 0 to remove and 0 not upgraded. Need to get 466MB/471MB of archives. After this operation, 2169MB of additional disk space will be used.

So, mind your space before installing it. Some package failed to be configured because of the

upstart

service not running. That’s normal, I think…   😛

Wew, I think I screw up a bit. I forgot to install the kernel. So, in the chrooted environment before go out and run the update-grub2 script, do this:

# apt-get install linux-image reiserfsprogs

Well, I am a faithful ReiserFS user (no troll intended), but for those who aren’t the

reiserfsprogs

need not to be installed. Oh, and I add a user and have it in a sudoer grup.

# addgroup contoh_aja
# echo "%contoh_aja ALL=(ALL) ALL" >> /etc/sudoers
# adduser  contoh 
# addgroup contoh contoh_aja 

Now, let’s get out from chroot and update GRUB2. Just type:

$ sudo update-grub2
Generating grub.cfg ...

And add some piece to this entry post. Now I want to boot my computer and try to boot into the new beast. You’ll get update from my tamed beast. Ciao…

== UPDATED :: Posting from new pet. ==

Now, let’s boot to the Karmic and do this in a terminal:

$ sudo apt-get -f install

This will fix the error during installation in chrooted environment. LASTLY, don’t forget to install all the Indonesian translation stuff. You do love Indonesia, don’t you? 😆

PS: Do that in Synaptic, don’t trouble yourself by using the terminal unless you are a rock star. 😀

Okay, adjusting stuff… bye.

Creating A Cheap Home Theatre

Creating A Cheap Home Theatre

A while ago I was complaining about the fallen quality of current theatres. So, I decided to make my own theatre and, gosh, awfully simple. I’m using plain computer running GNU/Linux Debian Unstable/Experimental and I’m using OSS 4.1-mercurial for my sound driver. I’m using cheap stereo speaker in front and connect it into the green female sound output. Then, I connect 2.1 speaker behind my chair. Then, I played the movie with mplayer. 

Btw, I’m using el cheapo Intel integrated sound.

I can hear the buzzing and have the experience just like current cinema, even better I can go and take a pee without ever afraid of losing any moment. Seriously, I feel more surround sound and no annoying teenagers that would talk during the show and I can set the room temperature based on my taste.

In my conclusion, if you want a good home theatre, you can buy 5.1 speaker about 700 thousands rupiah. A cool LCD projector would costs about 8 million rupiah, you could buy lower than that at Mangga Dua. Or, you could just plug it into your TV or to your LCD monitor (recently they use widescreen).

Or, you could go to your boss and toss an idea to use your Meeting room and have a team bond by watching movie together.  💡

No wonder DVD always few months late. But, hey, luckily not all good film at theater, Gamer and Idiocracy are the good example of that.

E17 Interesting Project

E17 Interesting Project

I must say that I’m very glad to know that E17 has undergone serious development not only to desktop, but also to mobile computing and other interesting ideas. Already I have several projects that would like to discover.

E17 various mode

When I ran the E17 for the very first time, I was introduced into a wizard to select few modes that available for E17. The modes are interesting because actually each sets which plugins shall be activated. The thing is, I want to have a custom desktop on a netbook. The greatest thing about E17 that I have found so far is it has low resource requirement and touchscreen-friendly apart from the keyboard-friendly.

Canola

The framework designed for touchscreen-friendly system, namely Nokia 810. No wonder it is part of  project Maemo.

Eyelight

An interesting blog post [EYE] shows that a component being developed to have Edje files as presentation (cmiiw). Edje itself is a sufficient, non memory hog, and seamless animation framework. So powerful even the KDE people have it in their library [QDJ]. Ah, the sweet open source, put all the goodies together.

This would be sufficient for the long run version E-Access, which another story to tell.

The many wonderful things of course comes with a great price, I have to spare more of my free time into it. Okay, may be no more facebook and graphical novel? Well, now I’m in the way of curing those addictions which is another story to tell.  😛

A New E17

A New E17

Last time I use Enlightenment version 17, known as E17,  was about more than one year ago. That time, I was sad because the daily svn snapshot Debian package repository was going down. I wasn’t even aware that the official Debian package of E17 was conflicting with it. So, I have a messy E17 system that forced me converted into Gnome + Beryl combo.

What is E17? Well, as far as I follow, it was intended to build a desktop shell (which GNOME 3 also trying to strive now). To put it in a common words, it was intended to put all the widget/gadget/applet (let’s just say module) as an integral part of GUI experience. The whole desktop was a shell itself and could contain any widget. Later on, E17 adapted a new shelf system which providing a container of those modules. Sadly for me, this container have a maximum dimension, so I could not stretched the analog clock module.

How is it that E17 have the best GUI experience for me?

For your information, my KDE4 setup was built to resembled my old E17. But, it won’t be like E17, it had big memory footprint. This was making a concern for me because of running Netbeans and sites that abused Flash too much will render my computer helpless. My Pentium D often would die on me in high load because of the extreme heat so I would restart the PC. For a note, I had an experience that I  had leave it as is and found the following morning my computer was running slow, but it would be a pain if I would wait a day to have my computer reponse rather than restarting it. Anyway, that was the suckiness of my PC.

ANYWAY,

E17 was tailored on performance and better user experience. It was visioned by the core developers as the most advance system in user experience yet it would have low footprint. How low? Well, it could run smoothly on Zaurus device.

The thing that I like from E17 is it’s way of configuring have fast effect and restarting it without restarting X would make my day if ever I’m in a boring state and need to tweak my system. It was using the own byte configuration file, but later following Freedesktop’s way of saving configuration file. It was at early times deemed to have real transparency, breaking the pseudo-tranparency (which btw also invented by E16).

Well, I haven’t investigated the new E17. But, it is more than usable than the old days. What I like from E17 is the paradigm which have contra with common paradigm of today software. That is, it would be released when it’s ready. When it will be ready? Dunno, I have run this E17 since CVS (2003/2004 maybe? cmiiw), the old SVN, the new SVN, using compiled version, live CD, and debian repo. Some functionality come and go, which sadly I sometimes found it too useful to be thrown away.

This is the sexiness of my E17:

Oh btw, I’m using GNU/Linux Debian Unstable/Experimental. And the site:

Official site:

Enlightenment Main

Enlightenment started as a project to build a Window Manager for X11. That was way back in 1996. It has grown much since. It still produces this Window Manager, but it has evolved to also cover Mobile, Wearable and TV UI needs for projects such as Tizen as well as traditional the “desktop” UI.

New themes/application/module site:

Home – Exchange

exchange is a place to share themes, applications and modules for the enlightenment shell

Kambing Spidol

After the collapsing, Kambing have resurrected again. It needs few hours thanks to the almighty Universitas Indonesia‘s bandwith to recover all of the contents (± 2 TB). Unfortunately, after we struggle to put down sotfware RAID 5, the server having trouble at performance. The popular (most accessed contents) were on the same hard drive making it an I/O bottleneck.

Well, Adin said we will resurrect the good ol’ software RAID 5. Meanwhile, enjoy the slow throughput like the rest of us. 🙁

UPDATE: Adin have done it. Now, the popular contents in RAID 5
