The RH for this week is IPsec.
The german translations are coming along at a rate of about 2 a day, like I
said it'll be March when it's somewhat finished.

The American Manned Space Program
February 4th, 2010
Well so much for the American Manned Space Program, of which I'm a big fan
I must add. But let's review what happened in the last 10 years. 12
years. NASA built the International Space Station together with the Russians
and other major contributors, starting in 1998. Then GW Bush announced the
Moon to Mars program, probably because going to the moon was easier than
going to mars. Then President Obama just recently cancelled the Moon-to-Mars
program and what we're left with is a formidable space station in orbit
and a space shuttle that's retiring at the end of this year (4 more flights).
So what has happened behind the scenes, elsewhere? Well we had the
Spaceship One win the Ansari X-Prize and Virgin founded Virgin Galactic so
that Spaceship Two can take passengers to a non-orbiting 5 minute view of the
rim of space. Also scram-jet engines have been tested in Australia but I
didn't find any conclusive evidence that they are building a scram-jet just yet.
Also there is a company out in the US that proposes to shoot resources into
orbit out of a cannon. They are promising cheaper launch rates than what
the shuttle cost by a factor of 10 or so. Then there is the space elevator
that everyone dreams of but the material isn't quite strong enough for it
yet. And then there have been a number of private space companies that
have launched payloads into orbit, these are fairly new.
Anyhow the president of the United States probably has more insight on what
technologies are best and cheapest and makes his decision based on that. So
perhaps one of these things appealed to him causing NASA to lose their manned
space program. Obama must be convinced that there is a better way and we'll
see in time what that may be, perhaps he thinks it's too soon to tell the world
. Meanwhile I read somewhere, that Europe wants
to go to the Moon by 2030 which is in 20 years time. But a lot can happen
in just a decade. The original moon program of the US managed to land a man on
the moon in 1969 in a decade of preparation with no experience on how to do
so, but the cost was so tremendous that they had to give it up. So for this
situation I can only look to myself when I was a boy and wanted something
real bad. When I didn't get it, after a while I didn't want it anymore and
I was glad I didn't make that decision. Perhaps this is what America faces
today and they'll be glad they didn't go ahead with a moon program just yet.
Time will tell.

24 Years of computing History
January 27th, 2010
I started using a computer when I got a Sinclair ZX-81 from a neighbour. That
was the year 1986. The thing had no tape drive and I had to keep it on while
I painfully copied BASIC out of a book to play a game. Anyhow today I have
the amd64 that you see in the chart below at the bottom. I'm planning to get
a new computer in June that will hopefully blow all previous accumulations of
CPU or RAM away. It'll run several VM's and perhaps I'll even dedicate a core
to seti@home again, we'll see.

My Linux experience started in 1994 with the 486 as well. In 1995 I started
putting FreeBSD on the machine though and stayed with BSD for a number of
years before going back to Linux to run vmware (I still have BSD vm's!).
Oh I should blog about the fate of these computers. The sinclair broke, the
commodore was sold, the sx25 was stolen, the 486 abandoned when I left Canada.
One PII-350 was passed down to my brother, One PII-350 was abandoned, the
AMD Athlon 1000 went to my brothers in-laws, The G3 iBook broke, the G4 is
passed down to my parents (I'm writing on it right now) and the P200 had a
tragic fall out a 3rd floor balcony. And I only have the amd64 left of all
of these.

Hackepedia in German
January 26th, 2010
I'm working on translating the 150 documents that I have stored on
solarscale.de into german. I have done 25 or so since yesterday and I want
to slow the pace a little, I'm hoping to be done by march with this.
Here is a
sample.

Old code from the past
January 24th, 2010
When I write and commit C source code to sourceforge.net I try to include
functions that I can reuse in the future. That's the sole reason it's at
sourceforge. However I just found some old code written in early 2001
which I sent to Theo de Raadt and it was my implementation of a pflogd which
didn't exist at the time. In the end it was Can Acar's code that made it
into OpenBSD also called pflogd. I realize now that my code is pretty wack
but I can still use some functions over again, for example the pcap code or
postgresql code may be able to be copied to a new program. But it's not
worth uploading this to sourceforge.
- Here is my implementation of pflogd
So you can download it and study it and see countless bugs (like I just saw)
and you can try porting it to current OpenBSD because somewhere along the way
this must have stopped working as it doesn't compile for me on 4.6 anymore.
Have fun!

Sun is no more
January 22nd, 2010
Well it's final. Oracle bought Sun Microsystems. Here is a picture that
has been circulating:
I first became aware of Sun servers in 1995 when I used a shell account at
Seneca College in Toronto which I was attending for Computer Engineering.
The first time I had to administer a Sun box was in 1997 at an ISP that used
an Ultra-2 for it's email operations. Sun and I had a love/hate relationship
but over time my respect for Sun grew. Last year I was able to aquire Solaris
10 and so this shall be the first and last purchase I made from Sun.

News (natally & proteus)
January 16th, 2010
- proteus the main solarscale.de VPS has an uptime of 1 year today, so far
so good
- natally, the tunnel/VPN server that I programmed has a fix where the
key for 256 bit AES is now full 32 bytes long instead of 16. This may make
it stronger from crypanalyses
