So, one lazy afternoon I've decided to test WordPress. I really liked it, so I decided to switch over from Blogger. My new blog can be found here.

GUADEC 2006 Wrap-up

2006-07-02T18:25:00.000+02:00

I've just recovered from my trip back home from GUADEC (it took me 23rd hours to get home), so a blog post is in order, while all the things are fresh in my head.

GOME is people. I met lots of cool, interesting and fun people, got to know them as persons, and can call them friends, and not just imagining hackergotchi heads when I hear their names :-) That social aspect is definitely the best thing for me about this event. And we had so much fun, whether it was talking about hacking, searching for the best ice-cream in town, having a rock concert or just partying at the beach.

I've attended several sessions, and I think the hilights have been Kathy Sierra's Creating Passionate Users keynote and Luis' inspirational talk about the future of GNOME (hint: GNOME is people).

From development point of few, there were many topics revolving around multimedia editing in Linux (Diva, Pitivi, Jokosher, Elisa and all things GStreamer), improving memory and CPU performance, in context of being usable in OLPC and Nokia 770 (which is owned by all the hip people, btw), but extending to the desktop also.

I have to catch a bus so I'll cut this post short, with just one negative side of my trip to GUADEC. And that's VIP mobile/internet provider in Croatia (part of Vodafone). Do not, ever, under any circumstances, use GPRS roaming from VIP. Besides charging more than 11 eu/mb, they actually require you to pay the bill *immediately* (inside a week), instead of paying at the end of the month, as usual. It's part of their "customer protection" program, they say. I fail to see how requiring customers to pay immediately (btw the notice was sent to house address, and it was obvious that the bill was made by roaming, so the user is not at home. wtf??) means protecting them.

Anyways, that problem didn't mar the perfect time I've had at GUADEC, I'm so happy that I was able to attend. I want to thank Collabora for sponsoring my trip and stay at GUADEC and thus making it possible to me to share this wonderful experience. Thanks guys, I hope to see you again soon!

En route...

2006-06-23T08:20:00.000+02:00

... to GUADEC! This is my first time I'm going to such a conference, and I'm all excited to meet all the wonderful people that make the GNOME community, to hack, learn and have a great time.

MDK will be there, giving a lightning talk about Diva (the upcoming 0.0.3 is gonna rock!), and I hope we'll do some hacking together (after mandatory beers :-). The Collabora guys will talk about their our vision to change world into a better place, by improving IM with Telepathy project. I've been involved with Telepathy project for a few months now, and we're doing some great stuff, and the guys involved are great, and I'm really looking forward to meeting them.

These two project I'm primarily interested in, but the list of people coming, and the scheduled talks, hackatons and other events are sure sign I'll be in for some sleep deprivation ;-)

The wonders of modern technology

I'm blogging this from the train. The coupe's got a power outlet so I don't have to drain the laptop battery, and my GPRS card magically works in roaming, and I'm very pleasently surprised. I really expected some shoddy train with barely working air conditioning :)

Some points to consider:

GPRS really is a great stuff for mobile net connection
Thank God I've got roaming! The place where I'll be staying while at GUADEC has WiFi connection, but I wouldn't last till then :-)
My home ADSL connection speed really spoiled me
I'm addicted to Internet ;-)

In the meanwhile, the underground forces...

2006-06-15T02:32:00.000+02:00

...continue their expansion and quest for world domination.

Davorin got his hands on Ubuntu installs.

My friend Davorin works at one IT education company, and he's open to the idea of exposing his students to the world of Linux. He's agreed to hold a short (up to half an hour) presentation, showing off and explaining the basics of Linux and free software to the students who want to learn "more" than the basics of computer usage (read: Windows, Word, Internet browsing), and giving away Ubuntu installation (+ live, which is a great feature) discs to the ones who want to experiment for themselves.

At the same time, the other friend considers offering Ubuntu install discs to the people buying bare (no OS preinstalled) computers in the computer shop he works in.

Porođajne muke...

2006-06-14T22:11:00.000+02:00

Drago mi je vidjeti da i dugogodisnji i napredn(ij)i korisnici računala bacaju oko na hrvatski prijevod, nešto što se obično smatra "uncool" za korištenje na tech-gadgetima, pa i računalima.

Stanje hrvatskog prijevoda u Ubuntuu (kao i u ostalim Linux distrama) je daleko od idealnog. Najgora stvar nije nedostatak prijevoda, nego, kako je Stjepan primjetio, vrlo niska kvaliteta pojedinih dijelova prijevoda. Mi smo u nedavnom projektu prevođenja zbog raznih razloga posvetili pažnju *novim* prijevodima (koji su, imho, dosta kvalitetni), no nažalost nismo stigli pronaći i i ispraviti sve gluposti u već postojećima.

Ovo nije pokušaj opravdavanja - svjesni smo da još puno posla treba napraviti, a i siguran sam da postoje ljudi koji su spremni prionuti i pomoći u tom poslu. No da bi cijela stvar imala smisla, potrebna nam je i (moralna) pomoć onih kojima su ti prijevodi i namjenjeni - dakle, Vas, ljudi! :-) Kad naiđete na gluposti u prijevodu, nemojte jednostavno proglasiti to Sizifovim poslom, prebaciti na engleski i nikad se više ne osvrnuti na hr_HR.

Umjesto toga, uputite svoj browser na formu za prijavu pogrešaka pri prijevodu te nam skrenite pažnju na učinjene propuste, a ako i odustanete od korištenja hrvatske inačice Linuxa, pratite i dalje s vremena na vrijeme naš rad.

Izašao Ubuntu 6.06 LTS (Dapper Drake)

2006-06-01T23:57:00.000+02:00

Za one koji još nisu čuli, izašao je Dapper Drake, inačica 6.06 Ubuntu Linux distribucije. Drake je dostupan u Ubuntu (sa GNOME sučeljem), Kubuntu (sa KDE sučeljem), Xubuntu (sa Xfce sučeljem), Edubuntu (za djecu, s naglaskom na edukaciju) i Server (pogodno za server) inačicama. Dapper je LTS (Long Term Support) verzija, odnosno bit će podržana u slijedećih 5 godina.

Dapper je dostupan i na hrvatskom jeziku.

Instalacijski CD je istovremeno i live, pa je sustav moguće isprobati i prije same instalacije, a image CD-a možete skinuti ovdje.

Vatrena Lisica

...ali, to nije sve! ;-) Uz lokalizirani Ubuntu dobit ćete i ovaj set noževa!...

Nije baš set noževa, ali mislim da imam nešto bolje za vas. Kao što sam naveo u prošlom postu, u okviru Ubuntu prevođenja, preveli smo i dio Firefox web preglednika.

Samo dio, iz dva razloga: prvo, Firefox, kao i cijela Mozilla, koristi svoj poseban sustav za internacionalizaciju, a ostatak Linux svijeta koristi gettext - Launchpad/Rosetta rade sa gettext prijevodima, dakle u okviru Ubuntua nije bilo moguće prevesti Firefox. Drugi razlog je nedostatak vremena i (ljudskih) resursa - naprosto nije bilo vremena za prevesti ga cijelog pa smo mogli birati, prevesti najbitnije/vidljive dijelove, ili ne prevesti ništa i tako jedan od najbitnijih programa na desktopu ostaviti potpuno neprevedenim. Odlučili smo se za manje od dva zla.

E sad dolazimo do lijepog dijela. Firefox se koristi na raznim platformama, ne samo u Ubuntu Linuxu. Bilo bi šteta ne omogućiti svim korisnicima korištenje na materinjem jeziku. Stoga vam predstavljam Vatrenu Lisicu 1.5. Skinite datoteku na disk, i s diska je učitajte i instalirajte u Firefoxu. Potom instalirajte Locale Switcher ekstenziju, odaberite hrvatski jezik, i uživajte!

Iako bi prijevod trebao dobro funkcionirati svugdje, nije mnogo testiran na ne-Linux platformama, stoga vas molim da eventualne pogreške (ako su baš jako grozne) prijavite u komentarima ovog posta.

Patak priča hrvatski!

2006-05-25T01:19:00.000+02:00

English-speaking readers: this is a blog post related to our l10n efforts in Ubuntu. It'd be weird to write about'em in English :-)

Pred 20tak dana, Ante i ja smo razgovarali o relativno žalosnoj slici Ubuntu (ali i općenito Linux) lokalizacije, te došli na ideju za jedan pomalo "očajnički" projekt. S 3 tjedna do krajnjeg roka za izradu prijevoda, odlučili smo organizirati cyber-maraton, masovno prevođenje Ubuntu Dapper programa koje bi trajalo 2 tjedna. Nadali smo se prevest 20tak programa, u najboljem slučaju do nekih 10.000 stringova...

Tri tjedna kasnije, prevedeno je preko 40 programa i komponenti, ukupno preko 18.000 stringova! Prevedena je i instalacijska procedura, Ubuntu vodič (koji će se vjerojatno moći kupiti i u papirnatom izdanju), dijelovi Firefoxa, a neustrašivi Ante priredio je i podršku za provjeru pravopisa i lomljenje teksta u hrvatskom jeziku, koja je sada dostupna u standardnoj instalaciji.

Projekt je bio fenomenalno uspješan, premašivši sva naša očekivanja!

Da ne ponavljam stvari napisane drugdje, sve informacije možete dobiti ovdje. Još jednom želim zahvaliti svim sudionicima projekta, koji su napravili odličan posao. Svaka čast, ekipa!

Rezultati PPP-a biti će dostupni svim korisnicima po izlasku finalne verzije Dapper-a, 1.6.

Rado priča o tome kako je HULK ostario, kako je potrebna "mlada krv" koja bi gurala inicijative i ideje. Mislim da je naš projekt pokazao kako "mlada krv" postoji i spremna je napraviti puno korisnih stvar - samo je treba potaknuti i organizirati.

Ekipa koja je radila na ovom projektu nije to radila iz slave ili želje za bogatstvom, već zato što su željeli pridonijeti zajednici (a možda i zbog svega pomalo! :-). Pokazalo se da ima sposobnih i produktivni ljudi, koji žele uložiti svoje vrijeme i trud ako se pokaže da će time napraviti nešto (englezi bi rekli, "make a difference").

S obzirom na uspjeh projekta, za vjerovati je da će se i u skorijoj budućnosti organizirati slične akcije - ako ništa drugo, ubuntu-hr tim na ovom maratonu stekao je dosta iskustva u tome što "ide" a što "ne" i koji su praktični problemi u lokalizaciji. Ta iskustva nastojat ćemo iskoristiti i u našem daljnjem radu, te se nadamo ovakvim uspjesima i u budućnosti!

I za kraj, da se osvrnem na cijelu priču s komercijalne strane. Moja tvrtka Rei jedan je od sponzora projekta, a s obzirom da sam i sam sudjelovao u projektu (u svojstvu revizora), može se reći da je tvrtka potpomogla i novčanim i ljudskim resursima :-) Kako smo orjentirani pretežno na Linux/Unix tehnologije, vrlo nam je zanimljiva perspektiva stvaranja Linux desktop tržišta u Hrvatskoj. Lokalizacija Linuxa je bitan činitelj u dovođenju Linuxa u domaća desktop/office/home okruženja, što je jedan od razloga zašto smo i kao tvrtka pomogli ovaj projekt. Vjerujem da spregom F/LOSS zajednice i komercijalnih igrača dobivaju i F/LOSS entuzijasti i developeri, a nađe se tu nečeg i za nas kapitaliste :-) U konačnici, najveći dobitnik će upravo biti krajnji korisnici.

An end of an era, and a new beginning

2006-05-02T20:56:00.000+02:00

Caveat emptor: this is one of those "what I ate today" blog posts...

I've got some big changes in my life recently. Changes I've been totally preocupied with, and now it seems like the transition is gone, and a good moment to reflect back.

In March, I finally finished my university studies at FER and got a degree. The degree is diplomirani inženjer računarstva (diploma engineer in computer science, which is roughly equivalent to western M.Sc degree). The studies have been a long and bumpy ride, with 2 years off to pursue non-academic goals, but overall it was a very positive experience in my life.

I've also made a nice wrap-up of the studies by choosing a somewhat difficult and definitely unique diploma project - my own operating systems (my friends can attest that sometimes I shoot very hight :-) I dig microkernel systems and it's been my long desire to tackle with one, so the diploma thesis project seemed a right time to do it. I doubt I'll be in position to do it in some commercial setup. Anyways, I've setup a small component-based OS on top of L4Ka::Pistachio microkernel, and I'm planning to release the source code (under the MIT/X11 license) when I get the time - in the meantime, interested Croatian readers can take a look at my diploma thesis [pdf, 2MB].

For several months before the graduation, I've nurtured the idea of starting my own business. After weighting all the pros and the cons, I've started the paperwork flow (which here in Croatia there's quite some) to do it. So here I am, a proud owner of Rei, registered for various IT services. I plan to focus on software development for the web and on Linux and other open source platforms, and doing Internet multimedia stuff (streaming), again hopefully on open source.

Today I've finally set up the webpage for the company, which wraps about everything needed for start. I'm already head over heels in stuff to do, and I'm looking forward to the future...:-)

Planet facelifting

2006-04-17T14:24:00.000+02:00

Evo napokon od mene jedan post na hrvatskom ;-)

Kao što ste vjerojatno primjetili, već neko vrijeme otvoren je planet.linux.hr, portal koji agregira blogove naših ljudi vezane uz Linux i open-source tematiku. Planet je otvoren suradnjom sa dobrim ljudima iz HULK-a, a moja malenkost uzela je na sebe dužnost održavanja istog.

Kako originalni izgled planeta nije bio bogzna što, u pomoć je priskočio Josip Lisec, koji je složio novi i puno ljepši izgled stranica. Njegov uradak trenutno možete vidjeti na beta verziji stranica (svakako pogledati i komentirati! :-), a nakon nekoliko dana ako ne bude problema pojavit će se i na glavnoj stranici planeta. Druge Josipove radove možete pogledati na njegovoj stranici ovdje. Hvala Josipu!

Novi dizajn uveo je i novi fičr, prikazivanje ikonica, odnosno hackergotchija postera, pa ovom prilikom molim ekipu agregiranu na planetu da mi (ako žele) pošalju svoje slikice/hackergotchije, a sramežljiviji će biti prikazani generičkom ikonicom predstavljenom na beta sajtu.

Diva 0.0.1 is out!

2006-03-31T18:57:00.000+02:00

Finally, after many months of hard work, we've released a first public version of the Diva, a new video-editing software app for Linux.

Diva is written in C# and using the GStreamer framework. Due to the GStreamer constraints, the first release supports only DV, WAV and image sources, and export to Ogg Theora, and probably crashes all the time. Nevertheless, check it out, and tell us what you think! And don't be shy to lay at our feet any and all problems and bugs you experience with it, by creating a bug ticket on the project pages.

And now for something completely different

2006-03-05T17:59:00.000+01:00

...from the last post. That was a look on the past - this time I'm looking ahead. I'm talking about Xgl/compiz, of course, and the newly arrived über-eye-candy for the Linux desktop.

In the anticipation of the new Dapper goodness, I've upgraded to the beta of the new Ubuntu version a few days ago. Since both Xgl and Compiz are in Dapper's universe, I thought I'd give it a try. I have nVidia graphics card so getting Gl/Composite to run was no problem. I've had those in breezy, now I just had to reinstall nvidia-settings and the other related packages.

I've set up Xgl/Compiz according to this howto. All went well and I enjoyed the newly found goodness, untill the next time I restarted my machine. I repeated the two commands but compiz started being evil to me - all the newly opened windows were located at top-left corner of the screen, and I've been unable to drag the windows around holding their title-bar. Strange, very strange. Trying out various voodoo recipies, I've managed to disable compiz' gconf plugin, and everythign worked well. There's something fishy in there ... anyways, the lines I use are:

    compiz --replace decoration wobbly fade minimize       cube rotate zoom scale move resize place switcher &
    gnome-window-decorator &

The next annoying thing I faced was keyboard problem under Xgl. For some reason Xgl doesn't treat keyboard the same way as X does - it does seem to load the proper xkb files, but the keyboard was set to US instead of HR anyways. Some googling around revealed a hack which fixed that.

    setxkbmap -model pc105 -layout hr -variant basic

The other keyboard-related problem is wrong mapping of Shift-Backspace keypress, which led Xgl to crash (Zap) each and every time, which was *very* annoying. Thankfully, the lazyweb provided the solution to that also (I've lost the original link):

    xmodmap -e "keycode 22 = BackSpace"

Now everything works perfectly and I'm a happy new Xgl/Compiz user! I've made just one more tweak, added a button launcher to the GNOME panel for quick access to Scale (ex. Expose :-). I'm using the xsendkey utility to emit F12 keypress to the root window:

    xsendkey -window root F12

I've put the launcher for this utility to the top-right corner of the screen, so it's very easy to locate using the mouse, and I find it easier to use than moving my hands to hit F12 all the time.

Here's the obligatory screenshot:

To really see the duo in action, you should watch this demo. It's big (~60MB), but it's worth it.

A lil' bit of retro

2006-02-04T21:52:00.000+01:00

It's been a while since I've last posted. I've been quite busy lately, finishing my grade school, so I haven't really had time (or the will) to write here. I've had a few ideas for the articles, but I didn't cared enough to sit down and research them, and I didn't want to post just another rant, so that went to /dev/null.

The today's theme isn't rocket science, either. Today I've read this article, exposing a cool xscreensaver hack. That reminded me of countless hours I've spent, first in front of a Commmodore 64 (my first computer), and years later, in front of the DEC and IBM terminals at University Computing Centre (SRCE).

While hanging there (I've met some great friends there, we used to hang around there and socialize even if we didn't use the terms at all), I've written a small game, a clone of Microsofts' Nibbles, for use on the DEC VT. It was one of my first C programs, and I believe the first one using the ncurses library. It shows if you look at the source ;-)

Seeing the terminal emulation hack, I decided I'd run my game under that. With some minor tweaks i got it to run under 40x24 with not-so-good terminal capabilities (cursor droppings and reverse video problems with ncurses). So without further ado:

Senko Software Proudly Presents An obligatory "intro", showing the year of creation, 1997. This is the oldest program I've kept sources to, and it brings back nostalgia. And here's the in-game shot:

Ah, the good ol' times when men were real men, women were real women, and small ugly text-mode terminals were real small ugly text-mode terminals...

Update: The hacked source, for usage with AppleII xscreensaver hack, can be found here.Compile with: gcc -lncurses -o nibbles nibbles.c.

There Be Dragons

2006-01-05T04:21:00.000+01:00

It's 4 AM, and the night is still and quiet. I'm sitting in front of my computer, lit by the pale light of the LCD screen, and I'm losing my mind.

My life for the past several days (excluding the New Year's) has been no different than tonight. Thinking, coding, debugging, debugging, debugging, ...

I'm working on an embedded environment project for my diploma thesis. I have infinite power over the computer, my software need not obey anyone's laws. Except my own, which I have to keep in my head at all times. Can't write them down, they're changing too swiftly. It's hard, and it's fun. The most challenging part is that I have to be aware of the entire picture, down to the every detail. From the overall design, down to the stack allocation and word width issues.

And it gets ugly. I'm using some 3rd party components (like libc), which aren't exactly bug-free. Just a few minutes ago, after a few hours of poking around in my code (debugger? what debugger? I'm lucky I have printf() :-) I've traced the error to strdup() and malloc() implementations. Great.. So, frustrated and tired, I just wiped out the entire malloc code and created my own, which leakes everything (no free()) but at least correctly produces usable blocks of memory. After I did this, I tried to remember what I was working on when the problem occurred...hm, who knows. I'm tired and I don't want to play any more...

It's hard, but it's fun. There's no hacking like kernel hacking.

Xroach for the new millenium

2005-12-20T12:05:00.000+01:00

Remember Xroach? It was a "cute" screen toy with pests rushing around in the screen, hiding under the windows, and you had to click on them to squash them.

Well, here it is, reloaded! The new version features new flashy vector graphics, it's freedesktop standards compliant, and has been released in secrecy, under the code name libnotify-0.3.0/tests/test-xy-stress.

Note that it isn't shown in its full glory, because my Cairo install is somehow screwed; there should be a nice sky-blue gradient there, for your viewing pleasure, while you're squashing the monsters!

Yeah, I'm looking at the fun side of some people'w hard work, but, seriously, it's cool. Go try it out and play with it (not squashing dialogs - i mean download, compile, test, use, report bugs, squash some in the progress if you really want the squashing bit ..)

2005-12-20T02:11:00.000+01:00

This is cool.

GNOME vs KDE - the history

2005-12-14T14:54:00.000+01:00

With all the fuss surrounding recent Linus' rant about GNOME, a bunch of "KDE rulez, GNOME is for idiots" (and vice-versa) arguments sprang again. Personally, I'm a satisfied GNOME user, but I also understand why some of my friends choose KDE, and why they like it. We have different preferences. This is good. Choice is good.

So this post isn't about that: it's about the history. The flamewars reminded me of my first contact with Linux GUI environments. 'twas in the time of fvwm1, xterms, when men were real men, women were real women, and small furry .. err, when NCSA Mosaic was still usable. Then, everyone agreed GUI on Linux sucked - bigtime. Smart people began working on a solution, sometimes coming to an extreme.

Sometime after, I heard about a cool new project, which aimed to be a free alternative to CDE. For a lack of a better name, and in spirit of CDE naming, it was named Kool Desktop Environment (they couldn't be Cool Desktop Environment, for obvious reasons :). I was excited to see this project (I learnt about it at the time of the first release, I believe), and if I knew more about C/C++/Linux programming I'd probably try to get involved... but I did not, I stayed in the CLI.

As for GNOME, I haven't noticed it until it was already a popular environment. I've used Linux oblivious to any GUI progress, until I replaced my old 15" CRT with an LCD monitor a few years ago - the text mode sucked, so I switched to X. I looked at what KDE and GNOME looked (& felt) at the time, decided I like GNOME better, and I still haven't changed my mind.

Anyways, enough with the nostalgia. I've googled a bit, and came up with several screenshots of early GNOME (from here, the official GNOME site, O'Reilly and Wikipedia) and KDE (from the screenshots page on the official KDE web):

KDE had a head start in 1996. This dates from 1998, I believe before the first release. Compare with its model.

A bit after KDE 1.1 release, GNOME shows off its 1.0, in 1999. KDE 1.1 looks polished here (already better than the original CDE, IMHO):

In 2000, KDE 2 adds more applications and features and shiny stuff. GNOME 1.2 improves a lot, but is clearly a KDE lookalike:

2002 brings improvements in toolkits, KDE 3 looks more shiny & polished than ever, with lots of applications. GNOME upgrades to GTK+ 2 and gets more apps:

In 2003 the paths diverge. KDE 3.1 and GNOME 2.4 have different visions and different goals, and that shows. The default icon teme as we know it today is set around this time (at least the screenshots would suggest that):

The present: KDE 3.5 with the "Conquer your Desktop" slogan, and GNOME 2.12 with the goal "Just Works[tm]". Both desktops are very mature, a lot of hard work has gone into them, and both are pleasure to use - just, to different user bases:

If you're still reading this, congratulations! As a small easter egg, I present you with a proof of how great open source community is: there's a scratch for every itch ;-)

I'm so 2.0

2005-12-09T02:21:00.000+01:00

I'm talking about Web 2.0, of course. The new buzzword. The cool thing of the year. And I'm in.

How did I came to this? It began with small steps: First I switched to GMail because it was way cooler than any desktop mail reader, and it was accessible from anywhere. Much later, I started writing this blog..

..and finally today I switched web page from ol' PHP scripts to a wiki. And not just any wiki, I'm using TiddlyWiki. It's an amazing piece of software, an entire Wiki in just one HTML page. Awesome (and terrifying, if you happen to look at the source :)

And just to show how serious I am, I also switched my personal photo gallery to Flickr, and I'm tagging this post for Technorati.

Brave new world...

PS. Oh, just to assure you I'm not going insane - no, I would not like a web-based office suite :-)

Update: In a surprising twist of destiny, I saw how my blog looks like under IE, and decided to do something about it. I'm lazy, so I picked one of Blogger templates. I even like this new look better.

Ubuntu is ...

2005-12-02T08:49:00.000+01:00

... an African word meaning "I have better things to do with my life than configuring Slackware all day".

Or Gentoo, for that matter.

This isn't a flame bait; I've been a Slacker for many years, and I have much respect for those two distroes. I just subscribe to the Ubuntu way.

Tell me what you listen to ..

2005-11-28T13:34:00.000+01:00

.. and I'll give you more of that!

This is what Pandora project (a child of Music Genome Projects) seems to do. You tell them the name of one song or artist, they search their database and create a radio station that plays that kind of music. You can fine-tune the selection ("I like it" / "I don't like it"), and see why the specific song is playing.

Totally cool!

They do this by having a huge database of songs with a lot of attributes which describe them, and I don't mean just artist / genre info, there's information about the vocals, the rhythm, the sounds, etc, etc ... or so they say. I guess the search is just an attribute matching.

Too bad this isn't more open. Currently they're using Flash. Dear Santa: This year I'd like an open web service provided by Pandora for searching for similar songs.

A long tradition...

In other news, I've recently found out that Ubuntu distribution has a long tradition:

<onkarshinde> reter: Which Ubuntu? 5.04 or 5.10?
<reter> 5.94

That's eleven years! :-)

Update: Of course, only after I blogged this, came the realization that the fraction represents the month, not the year. So, that's Ubuntu from Oct 2012. Hey, a time-traveler! I must ask him a bit about lotterry ;-)

The Missing Piece

2005-11-18T06:34:00.000+01:00

I've always felt that, no matter how good the GNOME desktop became, other systems were more productive and suited for regular users, always one step ahead. What was missing? The answer was ever elusive, until now!

Tonight, I've finally realized what is the missing piece, the "killer tool" that will help GNOME realize its full potential on the Desktop and Beyond, and in the process help me achieve eternal glory.

I proudly present:

The Desktop Cleanup Wizard [TM]

Currently this wonderful tool just sits in the Notification Area and displays the above message. Various studies have shown that users have never, ever, needed the rest of the functionality (such as actually "cleaning" the desktop), so I have not bothered to code everything in. If you do need it, please drop me a comment and I'll see what I can do.

On a more productive side: I've used Python and libnotify for this, and since there's currently no Python bindings for libnotify (until some changes are made), I hacked a small wrapper for myself. This is probably buggy and doesn't contain all the functionality present in the library (most notably, I've completely ignored callbacks), but nevertheless, here it is if someone wants it. The sample script that uses it can be found here.

Gmail Draft goodness

I've just spend a few minutes writing a mail, and chatting in the background, switching between my Firefox and my X-Chat all the time. Then, in one moment, I hit the backspace key, wanting to erase a character in my mail message, and before I knew it my browser went backwards in time.

That is, it left the current page and visited the previous page in history. The current page was gone, and all my message text with it.

Enter the tonight's hero: after visiting my Inbox in Gmail again, I've noticed a red Draft item in the thread in which I was going to post. Thankfully, just before my Backspace accident, Gmail saved the draft of the message.

Thanks, Google! ;-)

Brave new Ubuntu world

2005-11-03T19:08:00.000+01:00

My Ubuntu adventure continues! Since the last post, I've upgraded to Breezy proper, and was really impressed with how smooth the thing works. I also began preaching about it to my friends (well, just mentioning it at strategic times, in fact :), and got in an argument with zvrba about whether Ubuntu or Gentoo is better and why (yeah, I know, it's silly).

One thing that I've always held agains Debian, and now Ubuntu, is the principle of "if you need something, download it off the 'net". That's cool if you have broadband Internet connection, but here in Croatia most people are still stuck on 56k modems. Imagine downloading kubuntu-desktop over that ;-) So, I started thinking about compiling a list of mostly-used packages and putting it on DVD. The newly-created Croatian LoCo team liked the idea, so a new project was created: Ubuntu Ningi (this is an unofficial project, but we hope that the Ubuntu powers-that-be will like it). Check it out, tell us what you think, and if you have Breezy, upload your list of packages and help!

Oh, and as a side-effect, I've become a de-facto member of Croatian LoCo team, so now I'm in the process of officially registering with them :)

Breezier Than Thou

(I haven't blogged for a while, because I was too caught up and had little time to tinker with fun things with computers about which I could blog).

Yesterday I switched to Breezy Badger (Ubuntu 5.10) preview.

About my Linux distro history. I've started with Slackware as my desktop distro (this was around Slack 2.x or 3.0, ..). Since then I've briefly touched RH, Debian, Suse and a few others, but always kept returning to Slack, although I've preferred Debian for server setup. I also like GNOME; when Slackware decided to drop GNOME support, I started looking for alternatives, and found out about Ubuntu. Being Debian and Gnome based, I decided to give it a try (I installed Hoary Hedgehog release), and was very satisfied (as I hear it, many ex-Slackers like Ubuntu - is there a pattern?).

After a few monts, I've learned to totally like it, and was looking forward to the next release, primarly because I followed the GNOME development closely and saw many "exciting new and innovative features" (as PR folks like to say). I asked around and determined to make the upgrade when Breezy proved stable enough.

And it is. Folks, it really works! ;-) After downloading and installing ~500MB of software packages, I half expected it to crash and burn. Due to the lack of time, I finished the upgrade remotely, and rebooted. I expected it to not show online. It did. Then, I got home, logged in, and almost everything worked. The only two issues were:

GNOME icons - I had a custom theme, mixing Clearlooks with Industrial GTK+ engine. Something screwed up during upgrade, and I ended up missing many icons. I solved the problem by removing my custom theme (and applying the default), and then recreating the theme (you can do that in theme preferences dialog).
Keyboard layout - I use Croatian keyboard layout. After reinstall, US keyboard was forced on me, and gnome-keyboard-properties dialog couldn't change it (although I did select Croatian by default). Looking on Ubuntu forums, it seemed that precompiled keyboard definition was wrong, or something similar (i have zero knowledge about XKB), so I tried to force update it by manually setting keyboard layout in xorg.conf. Restart X, GNOME figured out that there was mismatch, asked me which keyboard layout I wanted, I selected "GNOME default" (which was set to Croatian), and voila - there's my layout. Seems like a bit of a black magic, but just because I didn't want to investigate the thing any further. It worked ;-)

Everything else works perfectly (so far so good ... ;-). Also, I had several nice suprises. I use Mono, so I installed mono and MonoDevelop. I fired MD up, selected a new Glade# project, clicked a few times in Glade interface builded, hit F5 and ... it "just worked [TM]!"

Now, I know things are supposed to work that way, but there always seems to be some catch. Always I had to tweak a bit more, or dig into terminal, or something. Not now; it jutst worked. Kudos, Gnome, Ubuntu, Mono & all other devs! Keep up the great work, and thank you for a terrific software!
