It’s simply amazing. I wanted to show gecko2@ a USB stick with both grml(-small) and MirBSD on it, using SYSLINUX, but this fscking laptop does not boot from USB stick. So, the ALIX.1c it is, or the VIA C7.

Update: the VIA C7 doesn’t, either. Phoenix/Award BIOS v6.00PG it is, 09/26/2006-ID-PCM7E-6A7L6EIIC-00 apparently (I learned today from gecko2@ that you can indeed use the “Pause” key on the IBM PS/2 keyboard to hold the output during BIOS POST). And I suspect the X40 just has USB Legacy support disabled, but won’t reboot now.

25C3 redux

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)?

mksh-current GNU/Cygwin32 binaries (snapshot)

2008-12-31 by tg@
Tags: mksh

An mksh-current cygwin snapshot I just built for smultron, our graphical artist friend from MidnightBSD (which, by the way, also packages mksh(1)). He just did this:

mksh Logo

We’ll see what we do with that “m”…

I’ve updated src/etc/ssl.certs.shar, read about the procedure. Someone might want to update the nss certdata.txt file (to mark them as untrusted); for OpenSSL it’s enough to have them renamed. Luckily, the CAs agree wanting to switch to SHA-1 (yuck, broken as well). Only, do they get a new root certificate (probably not), and where does an OS vendor get such news?

Update: This appears to be not needed, as per this comment. However, how credible is this person? Where is proof? I’d recommend everyone who has not yet read it to look at On Trusting Trust. Anyway, the CA certificates are now trusted again; let’s just hope the backdated demo intermediate CA was the only one generated in the meantime. We really need my SSL known_certs proposal, I think. What’s with these MD2 certs anyway? (end of update)

On other notes, we have a new logo for mksh, thanks smultron. Hand-editing SVG is so much fun ☺ no really, in jupp it works very well.

I also ported the e3 editor to MirBSD, it’s 17 KiB i386 statically linked (stand-alone) binary. GNU GPL, but good for custom-made (hehe…) install/rescue system bsd.rd kernels. I would like to add TinyIRC-MirOS as well, but need to get an exception licence for crunchgen(1) use.

Both tinyirc and mksh(1) now use TIOCGWINSZ more properly and aggressively. The shell, in particular, now always has COLUMNS and LINES set.

light bulbs

2008-12-28 by tg@

Yesternight, not only my server crashed in the softupdates code again (*sigh* two RAID 1 rebuilds and a lot of fsck(8)), but also one of these energy saving light bulbs (13W). This proves that they do not have a longer lifetime than regular bulbs.

I oppose the planned ban of regular light bulbs, because, although almost(!) all of mine are energy saving ones, some of the propaganda apparently is wrong, plus they are not good in situations where the light switch is used very often, or when the light is only on for very short amounts, such as in the entrance area of an appartement (say 1½ m²).

What did I do? Meh, just some bootloader hacking.

Today, we gained arc4random_buf(3), arc4random_uniform(3) in libc and arc4random_atexit(), which is undocumented, but called from _exit(2) and all exec-style functions via execve(2) and exect(2). Since omalloc(3) needs arc4random(3) anyway, it is no real overhead, but a great way to make modelling the pool stuff even more difficult. Thusly, arc4random_pushk(3) retires in favour of arc4random_pushb(3) but stays as cpp(1) define.

Riding on the minor bump, mempcpy(3) stpcpy(3) stpncpy(3) GNU style were added as well.

Next plans are: rewrite src/lib/csu for pcc, make a port of uw-imapd with (maybe LTMIRMAKE?), make the pine and alpine ports use it, make the php-imap extension work with it again, further improve src/kern/ stuff and maybe www/mk/

More deep changes are however still postponed until OpenBSD is merged better.

I also fixed makefs(8) again ☺

MirOS @ 25C3 Updates

2008-12-25 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!

Chaos Communication Congress upcoming

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! is an mksh(1) shell script able to convert from Subversion repositories (remote access via URLs, needs installed svn client) to RCS/CVS repositories (local access via pathnames, needs installed rcs(1) ci(1) co(1) GNU RCS, as well as cvs(1) GNU CVS, for rcsfile(5) handling). For more information, see the included help as well as the commit message.

If you have any improvements or requests regarding this script, please contact me or the miros-discuss@ mailing list. There is a discussion thread for it.

In case you didn’t, read cvs(GNU) a.k.a. The Cederqvist! Another source of CVS tricks is courtesy of «ThunderChicken:#cvs» and includes some from myself.

The 13.rcs(PSD) documentation and rcsintro(1) are online as well!


2008-12-17 by tg@

Today I updated a couple of things (Perl, OpenSSL, OpenSSH, libpng, Lynx, Sendmail) in MirOS-current. Should be pretty much all needed, and stuff should still be working.

XFree86® 4.8.0 is out, we’ll update once we have human resources to do it.

The next snapshot may not contain the newer X11 unless stable. If imported and stable before the #11 release (whose criteria include OpenBSD merge), it’ll be used there.

Today I’ve got an interview at a potential new employer. *crosses fingers* Wish me luck. Or employ me. (Donations to be used for travel and accomodation for “events” are still desired for all of us developers.)

mksh R36b

2008-12-14 by tg@
Tags: mksh

mksh R36b is out, grab it while it’s still hot ☺ There’s an impressive change list for a mere bug-fix version, and this is the first one where ahoka@ has contributed directly. Upgrade is recommended for all users. The new memory allocator has been backed out for stability.

MirOS-current has mksh R36b plus some changes from mksh-current, mostly renaming set -o utf8-hack to set -o utf8-mode denoting said technology is solid after ages of testing. MirOS-stable has R36b.

wb bleu (X40)

Yay, the IBM X40 is back. No explanatory letter, just an invoice over 0 € (funny), but it works. The BIOS clock was off by an hour, I suppose they have booted a Windows® — maybe its “driver” has fixed the graphics chip. So I can go back trying to build a working snapshot again.

And never boot a GNU/Linux, especially not KNOPPIX!

PACKSTATION rules! Even though I yet have to figure out how to use it for sending out a snail mail package.

Maybe I should just go and get stuff for soldering odem back to life, though. Anyone want to buy an otherwise perfectly fine working IBM X40 with docking station and laptop bag? It’s not used much even by the previous owner (french company) and in good state.

We have Mirzilla Firetapir now, but I need to figure out how to get a cleanly separated xorg-reachover port for MidnightBSD done… unless I’ll be porting XFree86® (client part only) over.

I’ll still be using nwt this evening for recreation. And the win2k box nocd has RANDEX in Cygwin, using tinyirc, irssi, and mirsirc. I should definitively create a webpage on the site here for randex. Maybe make a tinyirc port — once it can deal with SIGWINCH…

Some search engine bait: Tom Kohnen, thanks for your old nwt laptop. The MirOS OPTU-8 encoding does UTF-8 (WTF-8?) and CESU-8, while OPTU-16 can do UTF-16 in pcc. Mirzilla Firetapir is the Vutral name for Mozilla Firefox, ports/www/firesomething. Vutral too helped to invent the MirOS RANDEX protocol (entropy exchange over IRC), which has nothing to do with the Win32 worm, just random numbers. My graphician — smultron — needs to expand mksh and I suggested, besides letter spelling (em ka es ha, or for the English, em kay es aytch), or the “polish/klingon variant” (m’ksh), or the official expansion “MirBSD Korn Shell”, he call it “MidnightBSD Korn Shell”. The invalid ones were “make shell” or em kay shell, this is something else. On a side note, we’ll be having a logo for mksh(1) soonish.
