When should this blog start to forget? This question has been with me for some time now. The idea is that after some time data and metadata should get deleted. I'd like to see this in search engines such as Google, personally. So I should practice what I preach. I'm going to make this blog a first in/first out queue with a buffer length of 25 pages. This means that possibly in February of 2011 I'll start deleting January of 2009. We'll see how it goes.


A million eyeballs for Theo

December 17th, 2010

Recently, Theo de Raadt, the founder of OpenBSD and hacker hero has made this announcement. In it is an allegation that a member of OpenBSD put backdoors into OpenBSD code for the FBI. A code review will result of this. Just, who is going to do this? Theo then voiced his frustrations with the OpenBSD community because our trust level is too high with the developers. He wants us to be less lazy and review code and say something when something is out of the ordinary. He doesn't believe in Eric Raymonds statement of "many eyes make bugs shallow".

Here is my idea. I want a PAGER, or an EDITOR that reports to OpenBSD at what code I'm currently looking in, how long I'm looking at a certain section of the code, what host I'm from and how idle I am and of course the time of date. The editor or pager is voluntarily used by the community and gives feedback to the OpenBSD high command how many eyes really are looking at the code. Who is looking at the code is another question that may be evaluated because a novice programmer trying to read kernel code will likely get confused and won't be much help in solving complicated structures of the code. In the end I'd like a graph made that shows exactly what areas have been "audited" by eyeballs and which areas are neglected. It should also show which areas get special attention, perhaps indicating a non-bugfree zone. Anyhow I want to show Theo that we do occasionally read the code, and the small community does too. We're really small only a few thousand on the mail list according to majordomo, so... I think this would really really help us as a community.


New Plans in the centroid network

December 10th, 2010

If you haven't noticed already, I've switched the dns records for solarscale.de and centroid.eu to goldflipper.net solely. This is in anticipation of quitting the proteus.solarscale.de vps. Instead what I'm going to do for europe is buy a soekris router, that has no fans or drives and make that a permanent presence on the internet off my DSL. I'm keeping the goldflipper.net VPS for now. I've also been looking around Asia and Europe for a replacement VPS but I'm not sure I really need it. So why am I doing this? There is many reasons I'm going to list a few here:

  • proteus.solarscale.de's provider does deep packet inspection and has mis-identified one of my programs as conficker.c (an abuse case).
  • I'd really wish I could have a BSD VPS instead of Linux.
  • The OS available to proteus is opensuse 10.3 which is almost 4 years old.
  • They haven't upgraded my plan when they offered new stuff which really irked me.
  • Their user interface is broken and says nothing about traffic statistics anymore and it has been broken for a few months now.
  • They don't offer IPv6 connectivity and now is the time to roll that out.
Well that's just some of the reasons.


2010, a look back

December 10th, 2010

Last year we had it on December 23rd, this year a bit sooner. Here is a sum-up from the year that passed.

January 6th  - new project "cryologd" which encrypts log files

January 22nd - Oracle buys Sun.

January 27th - 24 years of computing history for myself.

February 15th - ordered Bruce Schneiers "Cryptography Engineering" book.

February 17th - OpenSMTPd bug identified and fixed.  This bug was a remote
		DoS on the smtpd.

March 9th - Wildcarddnsd at BETA_4.

March 16th - got a digial camera for my birthday.  Point and shooter.

March 20th - OpenBSD releases the 4.7 song about superpuffy.

April 18th - graphics on this blog were changed.

May 10th - ICANN releases International domain names to the public.

May 21st - My friend Dan Moschuk passes away.  RIP Dan.  You'll be 
		remembered always.

May 25th -  I registered goldflipper.net.

May 26th - I purchased a new computer, a Core i7-930 beast with 8 gigs of ram.

June 5th - this blog now uses PHP in order to serve random open source ads
		as well as easing the updating of the history.

June 13th - Facebook does IPv6 at http://www.v6.facebook.com, have always 
		used it since.

June 21st - Saturn, Mars and Venus are in a straight line alignment a very
		rare celestial event.

June 29th - Started Docking@home on my computer.  The project aims to help 
		cure diseases such as Human Immunodeficiency Virus (HIV).

July 3rd - noticed that some koreans tried to brute-force into my computer
		via pop3.

July 7th - coded SSL support in my fire irc client.

July 9th - saw the ISS for the first time in orbit from earth.

August 24th - Windows 95 turns 15 years old.

September 5th - coded Randombot which randomly searches for web pages out
		there.  ISP cuts it off due to it similarity with conficker.

September 19th - Wildcarddnsd-current recurses but is far from stable.

September 30th - Wildcarddnsd grows beyond 10,000 lines of code.

October 5th - the FSF turns 25.

October 25th - got OpenBSD 4.8 in the mail.

October 31st - helped fix an OpenSMTPd bug in the new DNS code.

November 21st - ordered 2 books from Amazon.  Pro DNS and Bind and DNSSEC.
		Both are excellent books.

November 26th - donated 10 USD to FreeBSD Foundation.  They deserve it.

December 10th - decided to scuttle proteus.solarscale.de vps in favour for
		a soekris board.
I have mixed feelings about this year...

Math Problem (angle to satellite)

December 1st, 2010

Here is a math problem. Get out your old Trigonometry notes and solve the following. A satellite (Galaxy 15 for illustration purposes) is 35,779 kilometers above the surface of the earth in Geostationary orbit. Given that the earth has a radius of 6371 kilometers find out what the angle from the ground to the satellite is given that someone stands at 49 degrees north. Here is a picture:

Line ACB is perpendicular to line EC (6371 kilometers). Line EBD is 6371 kilometers + 35,779 kilometers, so 42150 kilometers. What we're looking for solving is angle BCD.


Donated to FreeBSD

November 26th, 2010

I shoulda done this a long time ago but I finally got some money in my paypal account and I donated 10 dollars to the FreeBSD Foundation.

I hope they can use it wisely.

Ordered two books

November 21st, 2010

I just ordered 2 books from Amazon.de. One is Pro DNS and Bind from Ron Aitchison and the other is called "DNSSEC" I'm unsure of the author. The latter is a compilation of RFC's and other material related to DNSSEC, which I want to use in my implementation of wildcarddnsd. Hopefully the books will help me understand DNSSEC better so that I can implement this in the authoritative server side soon.


New patchrelease for wildcarddnsd

November 15th, 2010

I should have done this a long time ago but I just released the file wildcarddnsd-beta5p4.tgz to sourceforge, this has a fix that makes the tcp and udp interaction on the server more reliable. The download is here and the branch for BETA_5STABLE is here. If you get TCP requests to a running wildcarddnsd you really want to get this.

In other news, I'm delighted to say that people from Indonesia are the top downloaders of wildcarddnsd according to the stats at sourceforge.net. Thank you! Next are Indians and Russians in the top three. Thanks to you too. I noticed a lot of asians are interested in wildcarddnsd, which is cool.

As for BETA_6 it will probably take until next year. BETA_6 will have recursing and caching. It has it in -current now but it's broken somewhat and needs a good debugging.
