more bugs – bootloader and mksh

01.02.2009 by tg@
Tags: bug event grml mksh snapshot

Again. I almost have a MirGRML+bsd4grml ISO ready (exactly 72 MiB), just for the fun of it, and so that people can toy with it – and test the integration. But nooo, I even hacked a disklabel, yet it wouldn’t access the filesystem. The “machine label” command shows what’s wrong (and hints how to fix it), and I missed a corner case in disc I/O due to adding two not-so-independent-from-each-other scenarios during the El Torito merge.

mksh has funny behaviour with ${foo/@(%)/x} failing – only in Unicode mode though.

more bootloaders *grml*

Tags: bug event mksh snapshot unicode

To counter the bug in Parallels Desktop, I rewrote all of our Master Boot Record (mbrldr, mbrmgr), Partition Boot Record (bootxx), and BIOS disc detection code in boot(8/i386). I've also changed the magics, API etc. a little between these, rewriting or removing quite some parts of both installboot(8/i386) and bootxx.sh a.k.a. self-installing bootblocks. Oh, and MBR and PBR are smaller, or rather, have more room for informatory texts and data block storage now.

Lucas “laffer1” Holt from that cat's BSD helped me testing, qemu and bare metal IBM X40 works, so I suppose it's good. Can't test on VMware Server 2 right now.

On the other front, I'm writing this wlog entry on MirGRML, which is finally sort-of finished (which is why it has much less Unicode than a regular posting from my laptop). lynx-cur in sid is broken though, due to it using GnuTLS. Gah! Anyway, I see a sid “wtf” repo coming, and it was workarounded; next time I'll just do things differently.

Lukas “smultron” , the graphician of our partner project mnbsd, helped a little with the label (while I'm not versed in that field, if I had gotten the right material to work with I could've managed it all alone this time), and all that's left now is the Live-CD part and baking (and testing! even on sparc...) the ISO 9660 image.

There will be 297 MirBSD Triforce™ DuaLive™-CDs (two will go to Kiwi land to swishy, one is already reserved for XTaran) and 50 MidnightBSD Live DVDs at FOSDEM.

gecko2@ and bsiegert@ were not too helpful today, although I have to admit that real life often has precedence. I merely read some and went to sleep early yesterday too (and disabled both POTS and cell phone so that I couldn't be waked, haha!) instead of hacking late. Luckily, the deadline is not that dead, and I'll almost certainly make it tomorrow, in time. Thanks again, Daniel Seuffert from AllBSD.de, for all support you and others give to the smaller BSDs. Heh, and laffer1 is not quite done yet with his ISO (or UDF?) either.

Sponsor for FOSDEM

Tags: event

Sponsors make it possible for us to attend popular events, paying for travel and accomodation (we do not necessarily require a hotel, though, but it should be a clean place to sleep) cost. We are still looking for more sponsors making it possible to travel to even more events (Linuxtage Chemnitz, Essen, Graz, Luxembourg, for example) – flyers and CDs are already covered by AllBSD.de or ourselves, so it would just be that and, if you have money to spare, food and drink. Come and talk if you’re interested (in return, like here, we will publicly thank you or provide custom MirOS editions, possibly Live DVDs with binary packages, etc).

FOSDEM, the Free and Open Source Software Developers' European Meeting

Who’s not? ☺

My boss approached me just this morning… looks as if gecko2@ and I can use the bigger company car from here, expense paid, and take the other two who are going to Bruxelles with us. I’m in the process of organising them a hotel now though – maybe bsiegert@ the francophile can help with that. gecko2@ is going for a youth hostel though, as usual, as he has a membership anyway. Benny and I are already hotel’d.

Now if I were on Plänet Debilian…

SCSI-induzierter Rückschlag

20.01.2009 by tg@
Tags: bug event grml hardware snapshot

Heute hat mein Rückschlag, wenn man von den leichten Kopfschmerzen und der arbeitsinduzierten Müdigkeit absieht, einen Namen: SCSI. Ich wollte, damit wir mit dem neuen Snapshot endlich mal weiterkommen, tear aufsetzen (hey, ich schreib ja immer noch im Blocksatz im HTML-Quelltext ohne Mühe oder es zu wollen oder zu schummeln, wow) und dann kompilieren (quasi als Abnahmemessung). Dummerweise habe ich, auch dank gecko2@, nun eine Idee, woher die SCSI-Fehler kommen könnten, denn die Plattenprüfung im BIOS zeigt keine Fehler an. Ich fürchte, daß das LVD-Kabel kaputt ist (i386-Hardware ist eh doof, ein Kabel, ein Terminator und fünf Konverter von SCA auf UW-SCSI sind nötig, wo meine SPARCstation 20 das bereits als Backplane hat).

Es läuft vermutlich darauf hinaus, daß ich odems 2.5″ 80G IDE Platte nehme. Bonus: ältere cvs und Distfiles sind schon drauf, sodaß es mit einem schnellen rsync sowie einem erneuten Checkout (da ich / ja eh’ plattmache mit dem letzten Zwischensnapshot) gehen sollte, und ich sogar ein paar Pakete (zumindest IceWM) für den LiveCD-Teil backen könnte.

Toll. Ich habe sogar schon ein vorläufiges ISO zum MirGRML testen, bin aber irgendwie platt und auch von Technik mal wieder angenervt. So komme ich nie zu was… ich glaube, ich fang morgen mal so früh wie geht an, und bin dann ausnahmsweise schon wo’s hell ist zu Hause.

Also: Am Snapshot wird gearbeitet; mbsd4grml kommt direkt im Anschluß; grml-mir muß noch getuned (Konfigs), aktualisiert (lynx-cur UTF-8 Bug wo ich vorgestern drüber schrieb) und getestet werden; den sparc-Teil nehme ich vom letzten Snapshot; für DuaLive™ haben wir somit alles, Extrazeugs mache ich nur wenig und nur für i386, und für Triforce™ siehts gut aus – eine offizielle Ankündigung kommt auch irgendwann, wenn für beide Seiten alles funktioniert und integriert ist. Die tear-Migration ist – leider – hingegen auf unbestimmte Zeit verschoben. (Damn!)

Bißchen malen müßte ich noch, damit die FOSDEM Edition CDs auch sowohl das grml-Logo (habe ein OK von mika), den Shilouetten-Dæmon (altbekannt, mit OK von rcollette und mckusick), und ein Triforce haben. Es paßt mir, ausnahmsweise, auf Arbeit einen KDE-Desktop mit gimp und Inkscape nutzen zu „dürfen“ (peu à peu krieg ich den weniger nervig konfiguriert, und ㈠ kenn ich KDE 1 schon auf ecce!GNU/Linux 1.0 und ㈡ mag ich kmahjongg eh’ und konqueror besser als M*zilla Schrott, also ruhe da!, auch wenn ciruZ mir GNOME verkaufen will). Mal sehen, was ich da so hinbekomme. Wobei, à propos Bildchen: wann lernen die Leute eigentlich, daß man keine Formate wie JPEG ob ihrer verlustbehafteten Kompressionsverfahren herumschickt – zumindest zum Bearbeiten? *seufz*… Zumindest denke ich, daß ich das ganz gut hinkriegen werde, hab da was im Kopf, sogar ohne smultron, lediglich die Schrift könnte knapp werden, kA ob der schwarze Hintergrund in dünne Linien reinläuft. Mal Daniel fragen…

Ha! Laufend mehr Leute krieg ich vom RANDEX-Protokoll und den Vorzügen des Entropieaustauschs, Zufall allgemein, usw. überzeugt. Way to go! Nun bin ich gespannt, ob Vutral mal was zu APS findet und was man mit Mumble und randomness so machen kann.

25C3 redux

31.12.2008 by tg@
Tags: event

Did you all read my comment on the MD5 CA thing?

25C3 is over, gecko2@ arrived today, and both he and bogus are just too verpeilt – they forgot to distribute the MirOS flyers and CDs at first, then bogus (who had them) got really ill.

We all somehow are, at the moment. Get better, everyone. (replaced couldn’t get to the BSD@Wien pre-christmas party either…)

cnuke@ pointed me to a nice IRC quote:

17:57 < jtsn> Der 25C3 ist lustig. Deutsche Vortragende brechen
        sich vor deutschen Zuhörern auf Englisch einen ab. ;-)
18:01 < jtsn> Adolfs Werk war sehr nachhaltig. ;-)
18:01 < jtsn> Das gab's nichtmal in der DDR, das[sic!] Deutsche
        mit Deutschen auf Russisch reden. ;-)

This’ll be my ~/.etc/sig for a while… it does hold some truth. *looks at this wlog*

Benny is still alive, yet a little offline, hacking on perl stuff for MirPorts. Good riddance.

By the way: does anyone know of a way to use a web browser or engine, for instance Webkit, from a shell script to produce a rendered version of a HTML source file (preferably to PostScript® or PDF)?

MirOS @ 25C3 Updates

25.12.2008 by tg@
Tags: event

Word has reached me that Benny and Przemek are both suffering from illness (nothing bad, just a cold, don't worry) and thusly will not be attending the congress either.

As gecko2@ is currently preparing his machines, we believe he will uphold our representation at the event. Please join the IRC channel or the mailing list if you have any questions.

To these who do: happy celebrating!

I have just placed a couple of MirOS CDs and flyers (English and French only though ☺) in the hands of a friend while helping him to move to Berlin. Either him or Benny (bsiegert@) or Andreas (gecko2@) will distribute them at 25C3, or we’ll place them somewhere. I (tg@) will not attend, replaced (ahoka@) probably neither. You might be able to track down Benny in between some of the talks if you have any questions regarding MirPorts and MirOS, though.

To these who do, happy celebrating!

Zaterdag 13 September, Baarn, Nederland. Iedereen wacht op me. Spijtig dat ik niet kan komen. Ik wilde met een vriend die een auto heeft naar Baarn gaan, maar die komt op 10:30 ipv 09:00 CEST, en dan ben ik ook nog niet klaar met wakker worden, koffie drinken, zaken samenzoeken, voor’t weekend inkopen, enzo. Op 12:00 zitten wij in zijn auto… maar dat zijn nog 2½ uren (of meer) tot dat wij aankomen kunnen, dus wordt besloten, er niet meer te gaan. SFD was vanaf 12:00 tot 17:00… voor 2 or 2½ uren moeten wij 5+ uren in’t auto zitten, en dan is nog niet zeker of wij het Brandpunt vinden. Slechte planing. In het duits is er een expressie voor dat: “Verpeilungsfaktor” – Wij zijn dan in’t zwembad geweest.

Groeten an iedereen die daar was… volgende keer dan. Echt jammer dat het niks wordt. Ik geloof ik had te weinig geslapen verleden week, door mijn nieuwe baan in zwitserland.

Wij zatten dan gisteren nog in mijn favoriet kroaats restaurant, er wordt besloten dat ik de volgende tijd minder aan mirbsd zelfs werk, maar het nieuwe server klaar maak en de VM zo installeer dat ze een takeover van de oude www.mirbsd.org vhost kan maken. Ik doe mss eerst nog een snapshot, maar die komt dan zonder Live CD (die moet ik opnieuw maken doordat wij geen mkisofs met al zijn fouten meer gebruiken). Benny doet in de tussentijd meer met ports, bv. fixes voor ccache en distcc (zodat mijn SPARCstation cluster packages kan bouwen ☺) en enige Qt4 ports. Nadat de twee server’s klaar zijn kunnen wij dan verder met mksh, mirmake en zo doen, wanneer het werk nog arbeidsvermogen overig laat (da’s soms moeilijk). gecko2@ doet goeie werk met het opzetten van VMware voor eurynome, ter gebruik stellen van een IPv4, enzo.

Wir haben jetzt ein Blumenkohl-Icon fürs iPhone, Dank an die RUBIs.

Google ist definitiv evil. Ich vermeide sie auch so wie es eben geht, aber bei zwei Sachen habe ich keine Alternative, da sie entweder einfach nicht existieren oder saugen: Suchmaschine (ja ich hab sie alle durch) und Karten (bin halt Geocacher).

Während ich die 2⁶ Caches locker voll habe, siehe die diversen… Open, Free, Cool CommerceFrog Site Rare Jewels Broken Webpages² …Statistiken, fängt Benny erst an, immerhin 2³ hat er schon: Required in CH/F Kimnotyze macht nicht wirklich weiter… Lost in Luzern … gecko2 kommt selten zum Cachen, aber hatte letztens sein Vélo mit, sodaß er sich mit Kabelaffe und mir auf Tour begeben konnte: Janz Weit Draußen Und der Dr. Pfeffer findet in Bremen nichts mehr… wär er bloß mal nicht umgezogen, jaja… gibt halt nur in Bonn schön viele Dinger: Wallapampa
Aber Benny hat echt fieses Anfängerglück, und ich bin fachblind.

Bruscetta sind superlecker, aber füllen, zusammen mit der warmen Mahlzeit, den Bauch sehr an… und wenn man dann vorher noch einen Mojito hatte, hat man gar keine Lust zu hacken, ist ziemlich platt… erst bsiegert@ dann auch mir aufgefallen. Wir sitzen gerade bei N 47° 31.936′ E 007° 38.043′ im Chaostreff Bāsel… und sind ziemlich platt. Aber irgendwas kommt trotzdem bei rum.

Kommt wer mit nach Baarn und ggf. trifft sich mit uns $sonstwo?

FrOSCon redux

25.08.2008 by tg@
Tags: event geocache grml

Hum. This year’s FrOSCon… sucks. At least the catering, which was so much better last year (remembering the Chili con Carne, as well as the Chili non (sin) Carne, fondly… these were produced by wbx@’s family members, which haven’t been included in this year’s planning so some other persons did the catering). And being waked up at 04:00 in the morning due to a call on the mobile phone, for taking care of some drunken booth slave *grml…*, didn’t help either.

The evening’s social event also sucked totally. Since it had been raining until shortly before, they decided to have it inside, except the barbecue of course, but didn’t adjust the volume of the music played to the environment, which caused me to leave the MirOS/XF86 booth in favour of the Debian/grml booth, talking to Mika and Joey… who, like me, didn’t quite like being LITERALLY punched into our stomach by the basses. I left relatively early then, especially as the cocktails (Vutral brought me one, since I couldn’t go near the counter due to the volume of the… whatever they call music) tasted pretty bad and had a (too?) high percentage of alcohol. But talking to the various people, not just Mika and Joey, was good, even though just being at the FH (university) during the social event was really unbearable and physically endangering one’s health.

Other than that, we had quite a lot of fun at the conference, as usual. I still think it has chances to close up to FOSDEM, but they will have to make sure the catering does not get even worse. While FOSDEM does not have any catering, FrOSCon 2006 and 2007 had good food, and regressions count as malus.
Once I found Marc Aurele La France at the train station (which was quite a task), things went well – he even fixed a bug in our xdm configuration at the conference. The bug was inherited from OpenBSD, as usual ☺
Marc also said he enjoyed himself.

I hacked an Asus EeePC… MirOS mostly works (no NIC though), and the graphics card runs at 640x480 VESA… with the new 915resolution port of today, it might do the 800x480, but I can’t test now.

I took the chance to discover a geocache in St. Augustin yesterday, but, while Benny suggested we (him, me and gecko2) go caching in Bonn today, they seem to prefer hacking on the laptops (considering the weather, this is not the worst idea though), so I got time to write a wlog entry (too). I still have some things on my TODO, like fixing the ports with unfetchable distfiles, but hey.
Taking the day before and the day after the conference off is A Good Thing™.
Next one will be the Software Freedom Day in Baarn, Nederland – where not even Wim will go ☺ But I need a car… parents don’t help even if you ask them once a year, but maybe Jonathan from (near) Aachen will join me, he has a car.

My Thinkpad X40 will probably arrive today or tomorrow. Sadly, I didn’t invest any time in evaluating the products before… I learned that the ‘T’ series has 2.5" HDDs instead of the sucky 1.6" HDDs, and a much more solid lid chassis, at FrOSCon. My decision to buy an X40 was based solely on the observation that it was “in” at most OpenBSD developers some years ago (and thusly would most certainly work well with MirOS). Don’t do that then…

Once it’s there, I got to set it up and continue working. It’s bad odem broke so badly, especially as my current contractor (employer, except not quite so) would rather have me working full-time on the project, which is not entirely possible since I still have a life here. But upon setting it up, I might upgrade and/or fix some of the ports, since I’m at it anyway. Plus I get /home encryption.

Marc agreed to merging as much of our X11 changes (both these inherited from OpenBSD’s XF4 module and our own patches) into the XFree86® main tree, some ifdef’d, and helping us migrate to the new 4.7 or upcoming 4.8 release (or probably, 4.8.99.01, since I don’t think the merge will be there in time for 4.8 proper). He was a fun guy and well understanding our issues. The most funny part however was Thomas from Sourcemage (SMGL), who also maintains the mksh spell in their grimoire, considering to retain supporting XFree86® (and modular X.org, but not the buggy monolithic X.org) iff it’s still actively developed, which Marc assured me it is.

Benny agrees that the “Kaiser’s BIO-Kaffee” is decent, despite its pricing of only 3.99 €/£ (may be my high quality milk too, though).

Update: looks like I’ve got a package to fetch from the post station.

In my recent entry, I already talked a bit about pkg-config and its framework support. It turns out that there is another problem. The --libs parameter can be "split" into its parts by using --libs-only-L, --libs-only-l, and --libs-only-other. The LyX configure script, however, did not care about the latter, only the first two. Which brings me to the mail I wrote to the pkg-config mailing list:

"Hi,

"while compiling LyX/Mac the other day, I came across a problem in the way frameworks are handled. On Mac OS, frameworks are a different way to pack a library together with its headers. Framework-related options are put in --libs-only-other, while the configure script was only checking for --libs-only-l and --libs-only-L. While I agree that this is broken behavior, it brings me to my question:

"The way I see it, -Fpath (framework search path) is equivalent to -Lpath for libraries. Thus, -F should maybe be included in the output of "pkg-config --libs-only-L". The same thing goes for the "-framework name" linker option, which is more or less the same thing as "-lname", namely linking against a certain library/framework. Thus, the -framework option (with argument) should be added to the output of --libs-only-l.

"Opinions?"

In other news, FrOSCon has it second and last day today. I am currently in the train on the way. The party ("social event") yesterday was quite good, even though the weather was not as good as last year—it was cold and humid.
