Ordered OpenBSD 5.2 from Lehmanns.de

September 9th, 2012

Instead of ordering from OpenBSDEurope (sorry) I ordered from lehmanns.de this time. I'm saving money as it's only 39.95 euros there. And I can pay on delivery, and no shipping charges.


Could one of my dreams come true?

September 8th, 2012

Privately I had been dreaming of an optical computer. Photonics would do what electrons do in conventional computers. I imagine speed at room temperature and minimal energy (electricity) draw.

Now, my dream seems to have seeded in reality. See here.

Here is a good explanation of a NAND gate, notice it's functionally complete meaning you can create all other types of gates with this (AND, OR, XOR, and negated counterparts). Hats off Mr. Ritesh Agarwal for leading development in an optical NAND gate!


IPv4 Addresses Almost Exhausted in Europe

September 4th, 2012

This is the announcement from RIPE. Perhaps it's time to speed up IPv6 deployment.


Registered a new domain

September 4th, 2012

I have registered a new domain. It will eventually replace goldflipper.net. It's name is virgostar.net. When I was born virgo was the constellation in the night sky. The virgo star spica was surrounded on both sides by a full moon and uranus, but when I was born I became a pisces. Yesterday when I registered virgostar.net the constellation virgo rose in the east at 10 AM and the constellation pisces had the almost full moon in it. These were just some celestial observances I made with stellarium (with which you can adjust the date).

Also I'm going to be naming my computers after stars when I'm done with the planets, so this is a fitting domain just like solarscale.de domain was fitting with the planets. BTW I currently have control of six domains, probably a bit too many but I like them all.


How not to succeed (in trojan programming)

September 3rd, 2012

The german BKA seeks a trojan programmer. The BKA is the german equivalent of the american FBI. Let me brainstorm for you why this job is a dead end job, with no chance to grow.

  • Programmers seek hacker culture. I believe you can't take a single programmer and have them create 0-day trojan successfully. The programmer will always be a step behind virus makers and anti-virus gangs who enjoy a networked (perhaps even dark) underground where information is freely exchanged in form of malware.
  • It's likely a dead-end job with no job security. With that I mean the demanded results will never be fulfilled until the BKA seeks another rock-star programmer
  • This is a cyberwar attempt. Cyberwars require enourmous people resources which develop a "hacker culture" (as mentioned above), only these gangs can be successful in creating the tools they require, a single person can only dream of having the time (on the factor of 100) to do anything similar.
  • Job experience is a problem, there is likely a slight conflict of interest for the best people for such a job. One is working for the police, c'mon you can't likely feel good for a new piece of art that makes the rounds.
  • They'll likely use a programmer only to spit him out again. I've seen it happen in this world. And while an applicant is being used for their hard gained knowledge there is no return of knowledge back to them.

And a multitude of ethics come into play. Whose side are you on anyway? I know this job isn't for me judging by the job-ad.


Steganography: It doesn't have to be criminals using it

August 29th, 2012

This BBC article caught my attention. If you take a close look on my website (probably under private) then you may notice steganographic content. I've been doing this for a while now. If you can't see it, that's the point :-).


Goodbye Moon-man! RIP.

August 25th, 2012

Neil Armstrong has died. For many an inspiration!

I'm a firm believer the USA landed on the moon not just once but six times. Unfortunately back then the lunar program was not sustainable and they had to cease going there. Pity still.


Four more weeks of summer

August 25th, 2012

Summer is coming to an end...slowly.

Can't wait for Fall!


Pictures from my Fire-aftermath

No fun!


6-8 Weeks

August 17th, 2012

Unfortunately the fire that ran through my building caused my apartment to be unliveable. It will be restored in 4-6 weeks. Since this affects uranus which is off now, I have moved all dns and mail operations over to io.solarscale.de and goldflipper.net. This is the downside of doing email at home I guess, but fires didn't happen for a long time and are in all in all a rare event. I'm just glad I got a bit of time off work to get everything organized again.
