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
