Projects

gps-1.0.1.tar.gz (63.09 KiB) contains perl modules for accessing a Magellan GPS receiver.

cvsmetrics-0.1.15.tar.gz (34.82 KiB) is a tool for collecting and visualizing code metrics of files stored in a CVS repository. Needs postgresql, apache, cvs.

grouplens-1.0.0.tar.gz (9.24 KiB) is a perl implementation of the GroupLens protocol. Very slow. Needs postgresql.

mwforum-nntp-0.9.1.tar.gz (10.65 KiB) implements a simple read-only NNTP server for the mwForum available from http://www.mwforum.org/.

times-1.0.8.tar.gz (450.07 KiB) is a web-based project management tool that is tailored for student projects. It is used for a few projects at the Universität Stuttgart, Fakultät Informatik. See the manual. Needs postgresql, apache.

mp3idtree-0.9.tar.gz (5.03 KiB) shows all MP3 files in a directory in a tree grouped by artist, album and title. The informations are taken from MP3ID tags. The tool allows to change these informations and renames the file accordingly. There is also a command-line tool for listing MP3 tags. Needs perlgtk, MP3::Tag.

gnupod-ratings-0.92-3.tar.gz (132.19 KiB) contains patches and extensions to support reading and writing of ratings and playcounts for the gnupod-tools-0.92.

newton-0.1.2.tar.gz (8.05 KiB) contains perl modules to access a Apple  Newton MessagePad. Reading the cardfile is implemented, as is creating new holidays in the calendar. Needs Sloup on the Newton.

oml-0.2.2.tar.gz (248.30 KiB) contains the object modeling tools created for the OpenCAGE project (CVS).

compose-setup.exe (525.84 KiB) provides a minimal compose key for windows. I need it at work for my Sun Unix keyboard connected with an ASUSB converter to a PC. It reacts to the right control keycode (sent by the compose key) and provides german umlauts. See also the Delphi source code (224.85 KiB).

If you are also annoyed about having to download your phone invoices from a crappy web site instead of getting them per email, this is the solution: get-webbill-20100601.tar.gz (2.26 KiB) downloads the latest PDF invoice from Arcor webbill automatically.

Sony-Ericsson M600i and Linux.

Debian on a SMC WAPS-G.

mailarch-20070304.tar.gz (6.90 KiB) implements a stripped down IMAP-Server for only one purpose: run it on your windows box besides outlook and drop your old mails in the inbox. The script writes the content out to a maildir-like structure. Phase II will be a database-import with search-capabilities.

smb-rsync-20070927.tar.gz (2.15 KiB) is a simple script to syncronize files on the local host with a smb share.

Optimus Maximus and Linux.

Unfinished Tales

dvdada-20031222.tar.gz (20.63 KiB) contains definitions of MPEG headers and a tool to dump IFO files. This was the beginning of an Ada port of the dvd authoring tool from http://dvdauthor.sourceforge.net. Needs the adasl-1.4 container classes.

vvs-fahrplan-20031222.tar.gz (4.21 KiB) is a GNOME2 panel applet that displays the next S-Bahn departures for Stuttgart. Written in Python, needs ClientCookie from http://wwwsearch.sourceforge.net/ClientCookie/ and a online connection.

Patches

hotkeys.diff (15.21 KiB) lets hotkeys change other audio channels besides the master channel if shift or control keys are hold.

tpb-grab_only_defined.diff (3.08 KiB) lets tpb only grab those keys that have commands associated.

dvb-stv0299-signal.diff.gz (569 B) implements the signal strength and snr calls for a Siemens DVB-S rev 2.1 card. Ported from MultiDec.

900_xf86Events_sun_usb_keyboard.diff (2.24 KiB) is the patch for using all keys on a Sun USB Type 6 keyboard with XFree86 from http://www.infosun.fmi.uni-passau.de/~nils/type6/ respun for 4.2.1 in Debian. Get the source from sid with apt-get source xfree86 and copy it into debian/patches.

Lately, the key assignments have changed, perhaps because I have installed linux-2.6.0. An adapted patch is 900_xf86Events_sun_usb_keyboard_2.6.diff (2.75 KiB), and xmodmap.sun-usb-2.6.0 (1.60 KiB) is a matching .xmodmap.

kvdr-svdrpc-patch (5.85 KiB) lets kvdr-0.52 listen to vdr's return codes and automatically reestablish the connection after a remote disconnect.

Code Mercenaries IO-Warrior

For all those trying to get it working with Linux, these are my first experiments:

• I want to get it running with hiddev, but it doesn't register as one. Therefore I have patched hiddev.c (1.31 KiB) and hid-input.c (886 B) to recognize it.
• hiddev doesn't support reports with more than one value in one usage - but we need that. In a mail from Sergey Vlasov on linux-usb-devel at 2003-06-25 11:48:23 a workaround is proposed (my patch (1.20 KiB)).
• warrior.c (2.37 KiB) is a simple test program derived from tester.c from Jens Peter Holme that lets the LEDs on the development kit blink.

Update: There is now a linux driver available on the Code Mercenaries Homepage http://www.codemercs.com/.

Update 2: iowarrior-compat_ioctl.patch (614 B) for using a 32-bit userland with 64-bit kernel.

I have signed these keys:

http://www.g10code.de/p-card.html contains informations about a OpenPGP smartcard.
Using this card with gnupg-1.4.0 and a Kaan Kobil serial reader and openct on Debian sarge:

• apt-get install openct
• put this in /etc/openct.conf:
  

  reader kaan {
  driver = kaan;
  device = serial:/dev/ttyS0;
  };

• put this in ~/.gnupg/options:
  

  ctapi-driver /usr/lib/libopenctapi.so
  reader-port 0

• gpg --card-status should work now

Secure access to your mail account with an Ericsson M600i (using stunnel for imaps, pop3s, ssmtp):

• Generate a key for exim to use TLS. The supplied exim-gencert creates only a self-signed certificate without CA certificate. I made some modifications to create a CA certificate first: exim-gencert (2.48 KiB) (you probably have to change the names for your server). In addition to the CA- and server keys and certificates in PEM format you get exim-ca.der for import in your M600. Update: better create a server-type certificate
• Use exim-genstunnel (327 B) to generate matching files for stunnel.
• Add the following to /etc/inetd.conf (add -D 7 for debugging) and reload inetd:

  imaps stream tcp nowait root /usr/sbin/tcpd /usr/bin/stunnel -r 143
  pop3s stream tcp nowait root /usr/sbin/tcpd /usr/bin/stunnel -l /usr/sbin/teapop -- teapop -S
  

  I use teapop, because I prefer maildir, for mbox popa3d is probably fine.

• Add this to /etc/hosts.allow:

  stunnel: ALL
  teapop: ALL

• Check the setup with 'stunnel -D 7 -c -r domain.invalid:995' from another client
• Password authentication over SSL is already set up in Debian, so add your password for outgoing mails to /etc/exim4/passwd.
• see also http://www.pigstye.net/articles/2006/09/26/exim4-with-courier-imap-using-maildirs if you want to authenticate against /etc/passwd...
• M600 setup: check the extended settings, you need for incoming SSL on port 995, for outgoing SSL on port 465. Now you are asked to accept the certificate every time you check for new mails. Therefore you have to install the CA certificate: put the exim-ca.der file on a webserver and download it to the M600 (perhaps transferring it over USB is also possible). By 'opening' the file you can add it to the list of CA certificates.
• SMTP over SSL doesn't work with etch? recomplie exim-daemon-heavy with OpenSSL (see debian/rules); see also http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=390712

more Postscript fonts for TeX in Debian:

• put your fonts in a local texmf tree in /usr/local/share/texmf
• create /etc/texmf/updmap.d/30mallorn.cfg; eg:
  Map /usr/local/share/texmf/dvips/config/bfr.map
  Map /usr/local/share/texmf/dvips/lm/lm.map
  Map /usr/local/share/texmf/dvips/config/lucidaso.map

  Map /usr/local/share/texmf/dvips/config/ppls.map
  Map /usr/local/share/texmf/dvips/config/fnl.map
• run update-updmap and then updmap-sys

Using a NVIDIA 8600 GTS with Debian Etch:

• apt-get source nvidia-glx (for me it was 100.14.19-1)
• remove the version restriction on xserver-xorg-core in debian/control
• (optional - only needed if you need the 'CustomEDID' option) get the new driver package from NVIDIA (i'm using NVIDIA-Linux-x86-169.07-pkg1.run) and update the filename informations in debian/upstream_info
• dpkg-buildpackage ...
• install the kernel source, build the kernel module and install that
• install nvidia-glx
• My second display (a Iiyama flatscreen from 2002) didn't work correctly; the 1600x1200 resultion did get thrown out and even after allowing these modes the image was wrong. My solution: save the EDID infos (nvidia-settings can do that) of my other display (a Samsung from 2005) and use that on the Iiyama with 'Option "CustomEDID" "DFP-1:/etc/X11/samsung.edid"'

Using a Samsung CLP-300 with Debian Etch (and CUPS):

• apt-get install foomatic-db-engine foomatic-filters-ppds foomatic-gui
• go to http://foo2qpdl.rkkda.com/ - get and install the current package and ./getweb 300
• add a udev rule: KERNEL=="lp*", ATTRS{product}=="Samsung CLP-300 Series", SYMLINK+="clp300", MODE="0666"
• and udevtrigger
• add some queues: foomatic-configure -n clp300 -N 'CLP-300 Color' -c file:/dev/clp300 -p Samsung-CLP-300 -d foo2qpdl -s cups -o ColorMode=Color -o PageSize=A4

ASUS M3A32-MVP Deluxe and Debian Etch with Linux 2.6.27.10:

• Update to BIOS 14.06
• don't use the SB-600 SATA connector (red one), but instead the Maxwell (black ones); I had noticeable io waits with the SB-600 and my SSD
• For IDE with use_dma=1 use ATIIXP_IDE and set the storage mode in BIOS to IDE.
• USB2 doesn't work (reliable) - I'll look into a separate USB PCI card
• wireless: get a current HAL from http://snapshots.madwifi.org/madwifi-hal-0.10.5.6-current.tar.gz and install it and check that you don't have ath5k loaded.
• If you want to bridge ath0 in VMWare: http://madwifi.org/ticket/407 and on top of any-any-117d: http://www.linuxquestions.org/questions/linux-wireless-networking-41/why-is-wifi-internet-not-working-with-vmware-6.x-and-linux-kernel-2.6.22-587021/#post2905568. Workstation 6.5 works out-of-the-box.

Creating a backup of the Thinkpad T40p HPA Area. Many have done this (http://bellet.info/laptop/t40.html#the_predesktop_area), but my harddisk had a different size and layout, so here are my offsets (and a script to get them: find-hpa-regions.pl (670 B)).

• Unprotect the HPA in the bios setup
• Look at fdisk -l /dev/hda to get the last used cylinder. My harddisk has (with HPA protection disabled) 16 heads, 63 sectors/track, 116280 cylinders, Units = cylinders of 1008 * 512 = 516096 bytes, end cylinder of last partition is 110040.
• Dump the area after that to a file: dd if=/dev/hda bs=516096 skip=110040 | ...
• Run the script to get the offsets and length (some have to be merged manually; I use the offsets and lengths 6898 + 15063 = diag.img, 21961 + 15060 = diag2.img, 37021 + 6027264 = recovery.img, 6064285 + 15060 = recovery2.img) and carve them out with dd: dd if=t40p-hpa.dump bs=512 skip=... count=... | ...
• Mount the recovery.img, recovery2.img, merge them and create the ISO: mount -o loop,ro recovery.img /mnt/test; mount -o loop,ro recovery2.img /mnt/test2; mkdir recovery; cp -a /mnt/test/* /mnt/test2/recovery recovery; mkisofs -b bootimg.bin -c bootcat.bin -o recovery.iso -r -L -J recovery
• If you want to create an ordinary CD, create the WIN51 file described in http://www.howtohaven.com/system/createwindowssetupdisk.shtml and use http://www.nliteos.com/ to create a new CD

Using the extra buttons on a Contour USB mouse. See http://www.linux-gamers.net/modules/wiwimod/index.php?page=HOWTO+Mouse+Buttons for the general directions. I use this in xorg.conf:

Section "InputDevice"
        Identifier      "Contour_Mouse"
        Driver          "evdev"
        Option          "Device" "/dev/input/by-id/usb-Contour_Design_Contour_Perfit_Mouse-event-mouse"
        Option          "SendCoreEvents"        "true"
EndSection

I left the xmodmap pointer definition as is and use also xbindkeys and xvkbd; my .xbindkeysrc:

"xvkbd -text "\[SunPaste]""
  m:0x10 + b:8
"xvkbd -text "\[Return]""
  m:0x10 + b:9

Reassigning the keycodes for the Logitech Presenter, so that they differ from the default assigment (b, F5, ESC, PgDn, PgUp): linux-presenter.diff (3.03 KiB). The new X11 keycodes are: keycode 233 = Prev; keycode 234 = Next; keycode 151 = Play; keycode 159 = Blank.

If your keycode assignments don't work, hotkeys doesn't react sometimes or strange dialogs are popping up while you try to change the volume: it's perhaps the fucking gnome shortcut assignment. Run 'gnome-control-center', go to keyboard shortcuts and remove them.

ACER Aspire H340 and Linux (Debian Lenny)

• Connect the first hd to yout PC and create additional partitions, e.g.:

  /dev/sda1               1        2611    20972826    7  HPFS/NTFS
  /dev/sda2   *        2612        2861     2008125   83  Linux
  /dev/sda3            2862      121352   951778957+  83  Linux
  /dev/sda4          121353      121601     2000092+  82  Linux swap / Solaris

  I like a separate boot partition, so I can later encrypt the root fs.
• Mount them to a temporary directory (e.g. /dev/sda3 on /mnt, /dev/sda2 on /mnt/boot).
• Write a bootloader on it. I used grub and created a /boot/grub/menu.list (3.88 KiB) with small timeout, kopt=root=/dev/sda3 rw rootflags=data=writeback, groot=(hd0,1).
• Create the missing /etc files by hand: /etc/fstab (770 B), /etc/hosts, /etc/resolv.conf.
• If you want to use an SISVGA USB VGA adapter as console, put "options sisusbvga first=1 last=5" into /etc/modprobe.d/local (185 B).
• To enable the eSATA port, you have to disable the pata_marvell module, also in /etc/modprobe.d/local (185 B).
• Exclude the internal USB drive from multipath: /etc/multipath.conf (146 B).
• FYI: lspci -vv (24.35 KiB), /proc/cpuinfo (552 B).

Connecting to a Sony-Ericsson M600i over Bluetooth

• Install bluez
• Pair the devices
• Configure rfcomm in /etc/bluetooth/rfcomm.conf:

  rfcomm0 {
          bind yes;
          device 00:16:B8:8B:73:E7;
          channel 7;
          comment "Sony Ericsson M600i - Dialup Networking";
  }

• Connect to /dev/rfcomm0 with mimicom; you should now be able to enter AT-Commands

Microtelecom Perseus and Linux: http://www.montefusco.com/perseus/

• choose option [1] Volume
• choose option [1] SRC Speech RX Volume
• choose option [5] 5_lvl : 87
• press the menu button (left side), choose Key Input, enter a value between 0 and 100, press ok
• now press the menu button and select back this should save (don't use the right side back key you normally use to navigate the phone or you will quit out of the settings) keep hitting the menu and back until you leave the service mode menu

Mounting your Casio Exilim via usb-storage magically stopped working? Maybe it's an infestation of dbus and gvfs stuff. Try killing 'gvfs-gphoto2-volume-monitor' or for more permanent effect 'sudo rm -f /usr/share/dbus-1/services/org.gtk.Private.GPhoto2VolumeMonitor.service' (see Debian Bug #544483 and #544148).

Urlaub in Teneriffa März 2012

Optimus Maximus and OS X Mavericks 10.9: after some time, the keyboard updates only sporadically. This is due to "app nap" slowing down the timers and can be fixed by running 'defaults write com.artlebedev.maximusdriver NSAppSleepDisabled -bool YES' on the command line and restarting the driver. Keyboard language display doesn't seem to work either, don't know how to fix that...
