Diary: Technologies: AROS: Fall colors over the MESA...
Want to begin this article with a sad note: at the end of August my actual company decided to downsize and to change its location, and am among the laid-offs, so right now most of my effort in front of this keyboard goes in finding a new job in order to pay the bills and keep the apartment; hope to be able to dedicate time to my advocacy back soon (that of course means i will be employed): please cross your fingers...

[update in november: still no job, will let you know of anything].

The month of October looks like has been a bit unfortunate for this blog: several times, trying to look at the content, i was greeten from a white page: by the way the black-out (or white-out i might say) affects almost all the ilcannocchiale blogs: it is the second time that I sent notification to the webmasters about this and lately am starting to consider to move this blog in a more affordable platform, maybe even self-hosted.

But let's go back and talk about AROS. Right now the most important news in AROS front are the following ones:

As said last august, Krysztof "Deadwood" Smiechowicz ported version 7.5 of MESA to AROS, for now in software rendering mode only. Latter in the month he also ported GLU,GLUT and added a revised version of SDL that can use MESA. The addition of MESA as library allowed  people, especially Matthias "Mazze" Ruster to port some new games on AROS; among the contributions we have now Block Out II, a 3d Tetris clone, Abuse, a well-known platform game, a first attempt to port Open Red Alert (that later has been removed due to a bad bug in the upstream that prevent enemy AI to operate), 3d Pool Billiard (running kinda slow due to the software renderer, kinda playable if you keep the window at stamp size).

September news is that Deadwood decided to accept the Gallium 3d Bounty. Krysztof already started to meddle with Gallium 3d at the time of the MESA port; he started getting decent results, as seen in this movie here on youtube. Following those embrionic attempts, Deadwood compiled a version of GLExcess that includes the nVidia Gallium driver and, compared to the old software-only compilation, the difference is really remarkable.

The latest additions to the already rich porting gallery of Deadwood are the OpenAL/alut/ogg/vorbis libraries. Those libraries, as said from deadwood itself in AROS-exec, are used in several open source games to provide the sound experience; their porting will open the door, together with the perfecitoning of MESA and Gallium, to porting some open source 3d games, such as Warzone 2100, AssaultCube and Cube2; and is known the plan to use the hardware acceleration together with Cairo in order to improve Wanderer responsivity and performance, but as far as i know is all still related to Deadwood progresses.

Talking about 3d and Mesa, last month the e-zine The Vague came out for AROS using the last MESA port of Deadwood; e-zines are well known to amiga users thanks to the demoscene; though i was hardly been a follower, remember an Italian one made called Infamia - at the time even Tadsince1995 used to cooperate with it as coder - and reminding the experience I started The Vague. The AROS version is in the same .lha archive with the Amiga PPC and Morphos version; once double clicked the icon a requester ask to start either in full-screen (for 640x480 resolution) or windowed (as i started it being in qemu at 800x600x24 resolution) ,whether to use sound effects and the music replay rate. Nikos posted a youtube video of The Vague running on AROS here.

Its been exciting to see some good demoscene art and nice music on AROS: i liked The Vague and am waiting for further numbers, and possibly even more e-zines and (why not?) some AROS demos too :)

Last August the code of the Poseidon stack finally got released under APL and built together with the nightly builds, making so complete the Poseidon Bounty, the so far most contributed bounty in AROS history. I tried the stack on my old laptop, where a known incompatibility with the USB SIS controller so far occured, with November 12 nightly the USB devices are still not recognized, by the way. Once i find a way to download OWB from the nightly (writing the URL and then use wget to download it seems a good one), will post the dump of PCItool from my old laptop in order to help the debug.

Icaros 1.1.6 is already on the works but, since this blog post is kinda late, let me talk about the version 1.1.5, that I tried both as iso image on qemu and as live CD on the old laptop. So grub worked fine, but when I tried to select my sis900 network card with DHCP form the network control panel and press the "use" button in order to test OWB performance, the system froze hard. Everytime.
In defense of the network control panel, by the way, doing the same with the latest nightly worked pretty fine, apart the missing OWB in the nightly - beside an OWB folder and a OWB icon in extras/networking - for don't know what reason; i understand that OWB cannot be added to the nightly both for weight and license issues but my personal suggestionis to replace the actual useless directory with a script that might download the latest version on RAM, for new installs.

And, talking about OWB, our Stanislaw Szymczyk , after a while where he took a pause from AROS development, released another new version of OWB. The Version 0.9.9 is downloadable, as usual, from the sand-labs web site and this time introduces, beside the usual flattening of several bugs, a loader, called StartOWB, that uses the artwork made by michaels and helps to track the long first loading (caused by the fontConfig cache building); beside that, now the main application menus are finally available with the right mouse button as for every other AROS application, giving it a standard interface. As far as i know,  the AREXX port in OWB is still missing, but hope Stanislaw will fix this soon.

And then let's talk once more about the hidden hero of AROS, Matthias "mazze" Rustler: most of the software used on AROS has been ported by mazze, starting form several games (, then the unfinished port of Ignition Spreadsheet (that i still hope one day will be finished), LUA and its extensions, zulu and siAmiga - that are providing the base ground for several utilities, panels and give easy way for beginner programmers (like me) to produce something in AROS: the last fatigue of Mazze is the porting of Scout, the famous low-level tool for manage tasks under Amiga OS; undoubtely this might help to get rid of some annoying freeze of some shell windows or commodities, though for the well known lack of protected memory on Amiga OSes is still better to reboot the system as fast as possible.

Going further, any AROS user had to deal with the well known problems with our version of Dopus: despite being invaluable for file management, it has strong issues with advanced operations, such as extracting files, viewing pictures, even personalising buttons; this is due to the fact that this dopus port is pretty old (from 2000, if i remember clearly): now a new bounty  has been introduced in Power2people.org, for the port of the latest version of Dopus actually for Amiga OS-4 only; the bounty has been accepted by Neil Cafferkey and hope will improve this invaluable tool.

Last September once again Pianeta Amiga was held in Empoli, despite the fact that this year was held only at Saturday and the flow of people is really at its own minimum. This Year AROS was highly represented from, as usual Paolo Besser and, straight from the United Kingdom, Steven jones that brought its iMica platform. But here is the outcome according to Paolo Besser:

Thanks to Enrico Vitali and other well-known people of the italian Amiga community, the event has been amusing and interesting, but... well, I can't hide the mixture of bitter sweet feelings that left me only half happy. The good news, at least for Icaros Desktop, is that every visitor of the fair had the chance to see it in action, and most of them stopped at my table, asking for more informations or to see some demostration. I've also got many congratulations and many thanks for the effort, asking me for keeping up "the good job", but the bad news about all this, is that Pianeta Amiga this year lacked of visitors. Numbers had been fairly low (I've personally counted about 100 visitors) and the exhibitors themeselves were a tiny group that could comfortably stay in less space than the half area of the Palaesposizioni reserved to the event. "In the good old days you could see a crowd of people making long tails in front of the ticket booth - said Enrico while we were taking something to eat at noon - but today...", unluckily today's Pianeta Amiga loosely reflects the situation of the whole Amiga market. A tiny, fragile community which is hardly trying to keep its platform alive, even if the interest decreases a little more every year, and even if the whole IT market has completely forgotten the Amiga. So we have to thanks ACube, VirtualWorks, AmigaKit.com and everyone else that still persists, and spends money every year to organize a event which has just become a symbol, a tradition for the community, but which is practically perceived like a hobby, a nice meeting day with other people who share the same passion, even by people who professionally operate in the Amiga business.

It is sad for me to hear that despite the good news in the Amiga market (the SAM availability last year, the MorphOS on Mac Mini, icaros, iMica, Ares one, the settlement of the Amiga-Hyperion cause,etc., one of the last Amiga events is gone so unnoticed; despite my hopes, i think it is realistic that next year Pianeta Amiga might not be hold, if this is the trend; of course i expect thngs to change, but who knows....

Frustrations and disillusionment might hit even die-hard supporters. Many of the Aros-exec usual lurkers know Nikos: beside being a strong fan of the platform he is also one of the testers and one of the main bounty contributors ever, but in this thread he say that decided to take a leave from AROS, disappointed from the apparent lack of progresses, especially in the hardware acceleration section. By the way this happened just before Deadwood released its new MESA port and announced the start of the Gallium3d Bounty. The community reaction has been something you will rarely see in other open osurce community: almost everybody sent its own comment to nikos (including myself) expressing support; that convinced him to stay and luckilly for him, the new results on AROS seems to keep him busy...

Another AROS-friendly machine recently surfaced: provided by Pascal "Phoenixkonsole" Papara, the ARES one is an AMD Athlon x2 powered machine provided in a small tower case, bigger in size than Steven's Atom powered iMica; the graphic card is a performing nvidia GeForce 7200 with 256 megabytes DDR2  video RAM; phoenixconsole expects support from Gallium3d in order to enhance 3d capabilities; the machine hosts 1 gigabyte 800mhz DDR2 RAM (can be expanded up to 8 gigs) and can host up to four 5,25" devices; has a DVD/RW drive and a 3,5" floppy drive (foreseeing a catweasel support); it has a SoundBlaster Live as sound card and the network card is a Realtek RTL8139d that has a RTL8139 family chip and, quite interestingly, just today Hitchhikr released an rtl8169.device driver that in theory should support it. Paolone had occasion to test it with its Aspire One netbook and said it works nicely, adding another device to the netbook puzzle (right now still wireless and sound are unsupported on Aspire One).

Phoenixkonsole also plans to put in bundle with Ares One Icaros Desktop and a suite of programs for AROS including: the registered version of FryingPan and the incoming AROS Port of Cinnamon Writer: the latter one fills another software gap under AROS, presenting the first Word Processor available for the platform.

Cinnamon Writer is about to spice AROS

Now, if only Ignition port were finished we surely might had a decent AROS base office suite, together with MuiBase; the actual problem in finishing Ignition is non trivial. According to mazze itself in this thread on AROS-exec, it is depending from the actual order of "struct node":

Problem is that AROS has the elements of "struct Node" wrong on X86. This is supposed to be fixed with ABI V1. Unfortunately, Ignition makes *heavy* use of linked lists.
I could:
-continue porting when V1 ABI is released

-fixing list handling in Ignition which would be a lot of work which wouldn't be any longer necessary when V1 is out

-compiling me a version of AROS with the right order of Node. I could continue porting but I couldn't release the result until V1 is out.

All sucks somehow.

Further in the thread, phoenixconsole ask for how long might still take to Staf Verhaegen to finish the ABI 1.1; Staf's answer does not look too encouraging:

If I don't get help months to years from now. Problem seems to be that for being able to work on ABI V1 you need very good knowledge of AROS internals, Amiga OS internals and low level programming. It seems it is difficult to find people that have these capabilities and want to do it as their hobby activity. Additionally no glory or money can currently be gained by it.!!!

Staf is quite right: actually very few people have the required knowledge to help him in fix the ABI, and the actual AROS documentation, that should help provide that kind of knowledge is still kinda incomplete: lately even the quite famous "Linux lady" Carla Schroeder wrote two articles about the importance of documentation in Linux magazine: they can be found here and here, hoping to give guidelines for the actual coders, and maybe some non-coder to help therm in write it.

Simone "samo" Bevilacqua finally ported BOH to AROS, and it behave nicely even under qemu! BOH is one of the new generation commercial software available on the Amiga platforms (a little but, considered the platform diffusion, important avantguarde of a hopefully bigger production that include even Cinnamon Writer itself) and has been prepared for all the Amiga platforms so far: os 4, morphos and now even AROS. Despite some gitches with the sound due to the SDL libraries (and i expect things to imnprove thanks to the recent Deadwood work), the game runs fine even on qemu.


This coming year, God and Cash willing, is my intention to attend once more the Southern California Linux Expo in Los Angeles; will introduce the new features of AROS, the Icaros distribution, the new software and, if possible, even a native AROS box. Will write more about it soon; just mind that if somebody want to help me next february can get in touch with me at the email on the right side of the blog - the Get in Touch with Simone Bernacchia link, that I will repeat here, just remember to replace the sentences between square brackets.

Tecnologies:AROS:Anubis OS: Anubis, son of AROS and the "leap" legend
[Edit: sorry to have taken so long in publishing this since the italian version: been busy in my job and in real life.]

I would have liked to start this thread with some mythological tone, such as Conan the barbarian and similars, talking about heirs to the throne, heritages, traditions and other stuff like that: i sincerely admit i was tempted to do so.

I will instead start talking about a day, three weeks ago, when Michal Schulz posted a link on the #aros channel on IRC: this link.

It is nonetheless that the sourceforge page of what has announced this week from Damocles as Anubis OS, the latest incarnation inspired by Amiga OS, based on a Linux kernel and with a Graphic subsystem that, according to the Anubis mailing list, should be based on xcb,xlib and a mix of Glib/Gtk and Zune. Further details have been explained here.

In short, is their intention to do with Amiga OS what has been done from Apple in OS X: somebody already uised the term "carbonize".

From what both Michal and m0ns00n (Hogne Titlestad) told me, the main reason that make them start the project has been an essential steadfastness from other AROS developers towards more innovative goals: Damocles already complained about the conservative approach of many of the core developers. as i wrote here.
So, Michal, together with m0ns00n and Damocles started to define the base functionalities and requirements of Arix. Michal will begin tu put full steam on it once the Efika port will be done; task that is bringing along the comppletion of the USB mass-storage bounty, another important requirement.

In a following IRC chat session, Michal told me how Amiga OS seems to have an history of lost opportunities, both for management and markerting mistakes, but also for ego trips and "balcanization" of the resources. He thinks at ARIX (sorry i dont like the name Anubis OS too much) as the Amiga OS that should have been, with resource tracking, protected memory and all those features that first Amiga OS then AROS were unable/unwilling to develop for the known reasons.

Michal is a pragmatic person and for him the usual debate about whether if you use a POSIX kernel in an Amiga OS that ceases to be an Amiga OS is or not is over: he decided that it is and, i hope, wil prove it quite good in the future.

Anyway, has to be known that Anubis OS cannot be considered an AROS fork: technically AFAIK a fork happens when a project is duplicated and modified but, being Anubis based in a different kernel, figures as an indipendent project.

The announcement was taken not too good from the amiga boards: for the aforementioned reasons above and for the cronical lack of development that is afflicting all incarnations of Amiga OSes, a heavy FUD cloud spreaded around, like has rarely been seen before. The maini nconcern among other amiga users is the runaway of the already few developers towards a system that might not even reach an usable state, and the progressive death of the already existing systems.

Luckilly, open source projects hardly die: they might become unmantained until somebody else starts again to take care of it or integrates the code in their own project; luckilly for AROS this fate looks far from happening: the project look active as ever so far, and hoping this state will last.

And, like to show that AROS, despite the imminent departure of "Doctor" Schulz and the announced "pregnancy" (kitty is a female cat :P) is still vital, let's talk about the so-far spiritual heeir of the Doctor: Stanislaw Sszymczyk that, according to its job for the self-compilation bounty, now almost [edit: no more almost: done!!!] finished has achieved considerable result, such as:
 - non dynamic port of the latest versions of python and perl;
 - self-compilation at first in RAM, then under SFS of AROS in AROS;
 - extension of the POSIX layer compatibility adding instructions such as vfork(), wait() and waitpd();
 - DOS.library modification in order to allow soft-links;
Beside that, sszy also standardised the development packages in the variuous port of AROS under GCC 4.2.2 and included their compilation in the AROS build system in order to have a system of compilers and cross-compilers built for all targets.

Furthermore, Stanislaw gave a look to the sources of Netsurf and OWB; beside some minor issues, the browser can be ported quite easily starting from the OS4 port if the GUI was not a ReAction one; so Stanislaw is looking for someone (looks like o1i might help, and i want to mention ShinkurO due to its experience on workarounds for the zune bugs) to help hm in doing a zune GUI for it.
The OWB port looks a bit more complicated due to the fact that the Gladelib port is required under AROS and so far sszy was unable to do the port.

Another important update comes from the API completion report: Krzysztof Smiechowicz completed its review job that kept him busy since last april; according to its data the completion level of AROS is around 80%. This report is also the ground for a concrete roadmap to follow so that a version 1.0 of AROS will be available in a more human timelapse.

And is also a good step that finally in the mailing list somebody is starting to talk about the strong need for documentation. Krisztof Smiechowicz has already started in adding documentation on the ABI v1 here and hopefully some more important documentations will continue to come soon.

At last look also that somebody will finally take care of the printer.device in a laid back timing; about me i was looking and sent cdocumentation to the guy interrested to help himin the development, included the old Ghostscript port on AROS now no longer working [edit: seems a new port is on the way]; lets hope to see something soon.

Technologies:AROS: Going at a higher level of involvement
Well not one of my deepest posts today, more kind of a maintenance one...

Contributing to an open source project is - or at least should be - also a social moment: several people work together in their own free time to a common interest and a common goal. Things might be a bit more complicated when all the working people is scattered around several thousand miles between americas, europe and australia.

Let's tell the truth: if internet did not existed, probably not even open source communities might have been existed, or maybe not so much of it  and widespreaded as they are now.

The working and cooperation instruments are surely less evolved than the ones that can be found in a professional working environment, well not true: i used svn and vim in a recent task at work, and used eclipse in another; anyway, usualy many communication problems got solved through mailing list, instant messenging and IRC.

Despite IRC is considered "out" from new generations, is still a very useful and interesting instrument for group chat and talking.

i mention IRC because in the latest two weeks had occasion to find the "IRCous" skills of pidgin, my default messenger and miranda, the backup one; therefore i have been able to connect quite regularly in the official AROS channel; there "i seen things you humans cannot imagine", if i want to be geeky and cite Blade Runner...:)

It is quite exciting to talk directly with someof the most important AROS system and software developers such as Michal Schulz, Maag^da, Stanislaw Szymczyk and the others.

See Maag^da introduce its new Autodoc for AROS, having Szymczyk and Schulz talk "live" about the latest developments in their own bounties (congratulations, Stanislaw: the bounty is almost done!) and exchange with them ideas and opinions - despite is not a new thing anymore and despite i haven't been an avid IRC user but just a casual user before - is a step forward from being a simple forum lurker and an avid news reader: it makes you "be there" and get some job done actively.

I just downloaded LUA for windows and started to give a first look in SDLBasic, knowing the latter attempts of Mazze in porting it under AROS (with no avail at the moment). I also collected some ideas for some script applications i would like to do, not world changing utilities but still something...

[edit: i gave a first look at the zulu documentation: the lua/mui interaction look quite basic and low level, i sincerely hope to understand something on it; by the way, considered that i have to start from scratch, hope that in the next future will get i better...]

I am also trying to understand how to build some window themes, once i will find the way to make my virtual aros-box communicate with the network.
