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.

Diary: Technologies: AROS: Documentation Documentation Documentation brings Developers Developers Developers!!!
Hoping Ballmer did not patented its citation :P

Well, cause of my job duties this is not at all a new topic, but think is good to bounce it here. The Amiga Os 4.1 on Sam good new is a week old and probably, when it will be possible, will treat it here too but for now let's do business as usual.

One of the latest topic comments in my last article in the italian forum (translated here btw) was from Tadsince1995 and brought me to forward it and enrich it in Aros-exec:

(translated from italian:)
So, after Robert Norris, even Michael is going. The biggest problem is not only that they will not work anymore in AROS, but will be a huge disgrace the fact that so far those are the most prepared developers, therefore their own knowledge luggage, shared by very few little people, will be lost.
I (tadsince1995) always supported a "Documentation bounty" because there is a GRAVE lack of documentation for the low level part of AROS. Nothing about the USB stack, almost nothing on how to write drivers, etc. How an operating system can proceed if newcomming coder have no ideas in how and where to begin with?

Especially the fact that, obviously, people have other committments and there might be no time to do reverse engineering on the code, while having some good tutorial might save them lot of time.

And here is my enrichment:

I support fully the point of view of Tad: this is my personal request for Michael, for Robert, if he is still around, and for all low level developers: do not only leave the source available: do not assume people to have same skills as you: PLEASE DOCUMENT LOW LEVEL AROS, for the sake of future development following your contribution:

Amiga/AROS scene is too little to expect people to find enough documentation (outdated at most), and Amiga/AROS internals are too different from others to expect the inner workings to be understood easily.

Therefore the usual Open Source method to read sources in this case cannot apply fully.

[there was a withdrawn part to avoid discussions]

To the people still at work:

you know this project needs developers and, IMHO, if not a schedule -by philosophy-, at least it needs a post-it in the border of the screen where to step the fundamentals, in short: "a plan".

Forget one moment about ports: i think the system needs to be finished and polished. I have ShinkurO and others complaining sbout buggy MUI classes, myself in the verge to do a review of AROS for a magazine being a bit frustrated from the lack of visual feedback from the system as cursors or messages; LUA working but zulu not fuilly implemented in case somebody needs to write new applications, not only games (thanks mazze for your efforts in trying to build SDLbasic).

[end withdrawn part]

I feel emotionally involved with this project and , as Paolone, i think it has more potential than even eople here can expect. So, let's try to work in a synergistyic (collaborative) way and pave the street for newcomers as much as possible.

That is, my personal message at the community; i really wish AROS not to sink, i already said in past and will continue to say it in the future.

My personal contributions are actually in helping ShinkurO together with Tadsince1995 in translating its Programming guide for Amiga Oses and in writing a review of AROS for a magazine, even if both activities are going on slowly in the free time due to the aforementioned job duties.
