eclipse on sablevm and rants

"I must say that I am totally blown away by the progress made by the classpath, gcj, and kaffe teams (despite what you may have heard, kaffe is not dead). Free Java is moving forward at an amazing pace. Java is quickly becoming a viable Free development platform. This is an essential element for Java-GNOME's future success."

Fedora [mess] r us

"When Fedora Legacy is working well, it is a highly useful service. With a simple tweak to a yum configuration file, it is possible to keep an older system current with almost no effort.Unfortunately, the last update to Fedora Core 1 came out on December 3, 2004. Any Fedora Core 1 systems which rely upon Fedora Legacy for updates are currently vulnerable to holes in the kernel, xpdf, vim, KDE, PHP, sudo, etc. The process, it would seem, has come to a complete stop for over a month. We attempted to ask (via the posted contact address) what was going on, but got no response."

distributed version control - in the works by Martin

from planet.gnome.org

"Coders of the world rejoice, for Martin Pool is building a distributed revision control system:

I am not working directly on Ubuntu, but rather on improving the tools used by open source developers inside and outside of Canonical. The charter is to build a distributed version-control system that open-source hackers will love to use.

Knowing Martin, this will have the usability of Subversion and Darcs, the algorithms of Arch, and the pure leetness of rsync. Beware, other RCS authors: your days are numbered!"

Pascal -> Pcode -> Parrot -> Profit

Sven Schubert asked about the feasibility of putting Pascal on Parrot.
He noted that with the infrastructure mentioned in "Perl 6 and Parrot
Essentials" the problem would not be too bad. Apparently "Essentials" makes a few promises that we have yet to live up to. But we are working towards it. In the mean time, StEphane Payrard suggested a way for him to kill to bird with one stone: Pcode.

-- Pcode suggestion

quoted from parrot internals

Pascal Implementation: A Book and Sources

"Included here is the Pascal source of a public-domain Pascal compiler and interpreter, the P4 compiler and interpreter. It is coded entirely in Pascal, and produces a high-level so-called intermediate code as output. The program 'pint' is an assembler and interpreter for this language."

Mono SQL Query for GtkSharp
very good idea , now i have to read how to construct connection string in mono

Mono SQL Query for GTK# is a GUI client for entering and running SQL commands and scripts. Database objects, such as, tables and table columns can be browsed.

Mono SQL Query is built for Mono 1.0 and GTK# 1.0 or higher. It works on Windows and Linux. It has support for various databases via Mono's ADO.NET implementation and data providers, such as, Npgsql for PostgreSQL access or ByteFX.Data.MySqLClient for MySQL access.

Python vs Parrot

In many ways, it seems like Python and Parrot are from different planets.

In Python, the general approach seems to be to reduce everything possible to a canonical form as early as possible, and then deal with everything consistently.

In Parrot, the general approach seems to be to leave everything in its original form as long as possible, and then deal with everything separately.

The talk that Geoff and I gave went really well, and it ended up being as funny as we had hoped. More exciting than the talk is the project behind it. I think we've created the single best testing framework for PHP applications, and I'm going to try to describe it for those who missed the talk."

Compiler Optimization for Speed on an Athlon-XP System

"These results were obtained by running a script with different sets of optimization flags and measuring the run time results of the same floating-point intensive analytic code on the same set of data. The script cleaned and recompiled the code with the given set of flags, and logged the results. Inorder to reproduce the same background load on the machine each time, the xscreensaver daemon was killed, along with any other X-applications (such as mozilla, open-office, etc). The only other applications running were a few xterms, gkrellm, a window manager (Enlightenment in this case). Due to asynchronous loading of mail polling, and other monitor updates, there was an observed timing uncertainty of roughly half a second, meaning that run time differences of 1 second may not be statistically significant. For a more detailed discussion of the methology, flags, and results for other systems, follow the links:"

gcc powerpc options

"The -mpowerpc option allows GCC to generate instructions that are found only in the 32-bit subset of the PowerPC architecture. Specifying -mpowerpc-gpopt implies -mpowerpc and also allows GCC to use the optional PowerPC architecture instructions in the General Purpose group, including floating-point square root.

Installing open source linux driver for mustek wcam300

download the kernel and compile it folow this tutorial for debian
http://www.desktop-linux.net/debkernel.htm
then get the cvs version of driver

Patch for kernel 2.6 and a Makefile for 2.6. And some small bugg fixes.
So to compile with a 2.6 kernel :

cvs -d:pserver:anonymous@cvs.nw802.sourceforge.net:/cvsroot/nw802 login
cvs -z3 -d:pserver:anonymous@cvs.nw802.sourceforge.net:/cvsroot/nw802
co nw802-2.4
cd nw802-2.4
cp Makefile.26 Makefile
patch -p0 < patch-2.6
make clean
make

if it fails then go to lists

after kernel compile and driver patching is time for compile

make
ln -sf /opt/kernel-source-2.6.7/drivers/usb/media/usbvideo.h .
ln -sf /opt/kernel-source-2.6.7/drivers/usb/media/usbvideo.c .
make -C /opt/kernel-source-2.6.7 SUBDIRS=`pwd` modules

LD [M] /home/mariuz/tmp/nw802-2.4/usbvideo.ko
make[1]: Leaving directory `/opt/kernel-source-2.6.7'

then we should do modprobe for driver

su -c 'modprobe videodev'
su -c 'modprobe usbvideo'
su -c 'insmod nw8xx.ko'
dmesg | grep video
Linux video capture interface: v1.00

also at the end of dmesg

nw802.c: Potentially NW8xx supported cam found ( supported vendor/product IDs )
nw802.c: Detected bridge type : DivIO NW802
videodev: "nw802 USB Camera" has no release callback. Please fix your driver for proper sysfs support, see http://lwn.net/Articles/36850/
drivers/usb/media/usbvideo.c: nw802 on /dev/video0: canvas=320x240 videosize=320x240

install xawtv
su -c 'apt-get install xawtv'
then you should grap nice movies from your camer :) with this command
xawtv -c /dev/video0

Why linux (nv drivers) works on faulty hw

os linux drivers sometimes works even when the hw is faulty (when it shouldn't)
Had one gf4mx440 (elixir or something) and one day stoped working on windows (no hw acceleration even after driver/os reinstall) took the userlinux livecd http://hams.com/Mirror/userlinux-live-0.2.iso and booted .Was in the state of shock every thing worked (hw detected) , i could watch divx movies ...etc
Ok when i booted from the hdd (debian-sid) it crashed (black screen no signal)
What puzzled me was why it worked with live cd :) I know the board is dead (it will be replaced at vendor)

And the new nv linux drivers!
Just installed nvidia driver on my "borkstation" (userlinux aka debian-sid)
works great (gf2mx400)

And look what they have done with the new drivers ! :)

good cluster example
while searching on google for "athlon clustering linux"

http://www.tik.ee.ethz.ch/~ddosvax/cluster/

This series of benchmarks compares the Athlon XP 2500+, the Mobile Athlon 2500+, and the Sempron 2500+.

We put all three 2500+ rated chips through a plethora of performance benchmarks in order to see which of the three will give us the best performance for our dollar straight out of the box.

Now there is mention that the Sempron 2500+ rating is actually in comparison to relative Intel Celeron CPUs (since they are after all it's main price point competition), but after years of having AMD promise me and the world that it's performance rating system was based on some mythical Thunderbird processor and NEVER the competition I don't buy it. You're not allowed to rate two chips at identical 2500+ speeds without so much as an asterix and then tell that they're not supposed to perform similarly. The same goes for the Mobile Barton Chip.

Added release notes on freshmeat page and on the theserverside.com :

"Thank you for posting a news article on TheServerSide! Your article must first be authorized by a member of TSS staff for relevancy, clarity, etc. It may be slightly editted for grammatical/formatting errors, etc."

Here is the full release announcement done by Roman:

"Hi,



JayBird 1.5.2 is available for download. It contains fixes to the issues posted in this group. There should be no more "invalid statement handles" and result sets should be correctly released when using the connection pool.

Hopefully also the "cannot start transaction, local transaction active" is gone too, at least I have added some more fixes.



Additionally I made it possible to specify both isc_dpb_lc_ctype and charSet encodings. In this case lc_ctype is passed to the database, charSet is used to convert bytes to characters. Most useful case is when lc_ctype=NONE.

Previoulsy driver used the default JVM encoding to convert bytes into strings, now you can enforce the encoding you like and do not depend on the regional settings of the host OS.



I have tried to build it with JDK 1.5, but it was not successfull. The build system cannot run with 1.5 (the target="1.2" part in build.xml and the used version of Ant does not understand 1.5), and at least JNDI code from the pool does not compile due to use of generics in JNDI API. Most likely one can build driver by using the "compatibility" mode of the compiler, but the

build system must be fixed (probably requires upgrade of Ant). I think we would need to split the code bases the same way I did it for JDK 1.3 and JDK 1.4. Are there any volunteers for this task?



Roman"

WINDOWS MEDIA TEST (on linux) - Thanks MTV2

We have detected your browser does not have the required Windows Media 9 plug-in to play this video.

ps: this was when you try to play some videos on them site (Yah and i'm on looonix)
A good interview http://www.linux-mag.com/2004-07/rundgren_01.html
No wonder there are no good videos on MTV ... or music

LM: Do you ever want to create a new groundbreaking music video with modern technologies?

RUNDGREN: I do, but there's little demand today for music videos. There used to be a thriving, hungry market for music videos, but now most of the so-called music video outlets like MTV and VH-1 are doing reality programming -- they're not filling up their time with new videos. So the obstacle for me isn't daunting technology, it's simply the fact that there's nobody to play the result.

Funny System crash - quoting from [Bacula-users] mailing list

About twice a year I succeed in crashing Linux, usually by hitting ctl-C

while something is going on with my tape drive.  Well, tonight, I

totally froze my system. Even the little CPU meter stopped working. At

the same time, the CPU was going full out -- I can tell because the

cooling fan starts speeding up.



What is interesting is that I noticed the num-lock and caps-lock lights

blinking in a way that reminded me of something. After a few minutes, I

realized it was sending Morris code.  Now, my Morris code is *really*

rusty, and though I know all the letters, I cannot recognize them very

fast, so I got:



..-.  then waited until the message repeated and got ..-.  .- , then

again (really painful) ..-. .- - and so on.  I finally gave up after

getting:



..-.  .-  -  .-  .-..  .  .-.  .-.  ---  .-. (etc)



For those of you who do not read Morris code:



..-.  .-  -  .-  .-..    .  .-.  .-.  ---  .-.

Porting from oracle to firebird - howto

First i downloaded the opendbcopy.sourceforge.net and installed it
After that i used the jdbc driver (jaybird) for firebird and the jdbc driver that is with oracle 9 (copied jars in the lib directory)
Then i clicked on the DDL plugin and configured the drivers for source and destination databases and executed it choosing all tables from oracle database .
Then after xml files are generated is needed to run the ant tool to create the sql script for firebird .Here you need to download the latest version of ant tool
In my case i installed it in /opt/ant and after reading the manualexported these variables ANT_HOME=/opt/ant, JAVA_HOME=/opt/j2sdk1.4.2.x

Go to the OpenDBcopy/plugins/opendbcopy.schemageneration and
run >ant hbm2java
and then
>ant create-schema

for me it gave an error to at one table : " composite-id incomplete must match
"(meta*,(key-property|key-many-toone)+)"

so i had to move manually an table then it showed to the prompt BUILD SUCCESSFULL and database schema was created and could be viewed with

$view sql/Firebird_schema_create.sql

After this euphoric moment is time to go with another step :
pumping the data between the two databases (run the "Copy data from a source into a destination datbase" plugin)
So run the generated script into new database, for it gave some errors so i had to tweak some fields generated for example : numeric (19,255) to numeric (10)
(19 is too high for firebird - more than 64 bit precision ! )
Also oracles NUMBER is replaced with equivalent FLOAT from firebird , DATE converted to TIMESTAMP.
Another thing is about keywords like "value" or "time " - you must quote the table names , and columns if want to use it
A good tip from opendbcopy manual is to disable the fk before data pump so i did .
In plugin area there is "Create Insert scripts for destination" and could be used for the same purpose. For that plugin is good to inspect the sql files generated and quote every timestamp value (it can be done with %s/\.0/\.0'/g in vim for example)
SYSDATE references need to replaced with CURRENT_TIMESTAMP in the sql code (in fyracle you don't need to replace it - is done by the driver)
Sequences from oracle will be replaced with Generators

keyboard is dead on the flamebird system (amd386sx) and i can't boot linux on it becaus
e have to press F1 but how can i press when keyboard is broken ? I will try later to debug
it and to find what is wrong . Now the internals (hdd , netcard,io card, video card)
are installed on an intella 486dx (@25mhz i think). It works better than 386 (memory bus is on 32 bit). Have to add second isa network card to it and install / configure shorewall (it will be a router /firewall )

Well finally i finished chapter 6 of TICPP, now is time for reading the 7 :)
update : the chapter 7 is 70% read
update : Chapter 7 is finished and now i'm at about 10% from Ch.8

Reached to chapter 6 of Thinking in CPP. Got some din 5 to din 6 adapter for about 1$ so i don't have to kill a keyboard :)

converting my keyboard from 5-pin DIN (AT/XT) to 6-pin Mini-DIN (PS/2)
Well i have an old pc (386) and brand new converter doesn't work so an hp keyboard must be destroyed and 5-pin DIN adaptor will be used for a new keyboard (experiment :))
more about ps/2 interface http://govschl.ndsu.nodak.edu/~achapwes/PICmicro/PS2/ps2.htm

Finished chapter 4 of Thinking in c++ and
started reading the Knuth book The Art of Computer Programming
And there is a new version (0.1.3) of flamerobin


my to do list:
- install mix emulator http://ftp.gnu.org/gnu/mdk/
- buy this book
- cut and paste into new colored icons from flamerobin screenshot

ps: well i finished with my exams :) and feel better about it

Just Unmaried - or yet another strange dream.
I wake up sweating this morning , guess what: was dreaming about going to my wedding and all the ceremony . When we reached there i talked with my future wife and told me that we are not
ready , i agreed and that's all (I think the priest was a littel upset about this). Also remember that my father was there too .

ps: now that a strange dream ;) (maybe was the reason i wake up at 10AM) Usually i sleep until 1 PM

So tired of everything

Feel like i need another vacation , the "good" news is have an exam on Maths
(Topological spaces)
