What does the future hold?

June 14th, 2010

I have 4 sourceforge projects. Natally, Wildcarddnsd, Cryologd and twh. What is the future for them? Well I've given it a bit of thought on my summer break and here is the rough outline of the coding that I want to do.

Natally does tunneling real well. And it's encrypted however what I'd like to see from it is that it does address management as well so that clients connecting to it can connect to each other through the tunnels. Also when IPv6 comes along on my VPS I'd like to do a NAT feature for IPv6 because the addresses given to my VPS are going to be finite and I want to make use of them with the tunnels somewhat.

Wildcarddnsd is growing. The next big change planned for it is going to be a recursive server that allows me to change all my nameserver settings in resolv.conf be changed to my wildcarddnsd servers. The complexity is quite high so this may drag on. In my planning I've included an ascii drawing in the code for the code execution flow on how I think it should be done.

cryologd has been doing pretty well. Other than a condition where it exited for no reason (I think I got that fixed) there is not too much that needs to be done. One thing that the crypto code needs is an HMAC at the end of each frame for authentication which gets rid of the password exchange which may make this code a bit more robust and fluent. Changes going into cryologd can also be ported to natally as that's where it originated.

twh has been considered for removal on sourceforge. I don't plan to do development on it anymore but having the code resource on how to do the Berkeley DB stuff for example may be a good thing to have. Wish I had the time for it.


Facebook does IPv6

June 13th, 2010

I read that facebook is IPv6 capable at the address www.v6.facebook.com. This is great! I'll try it out when I get home.

Changed blog to PHP

June 5th, 2010

I've changed the blog to use PHP. I did this because of the following reasons:

  • I'm learning PHP anyways, last I used it was in 2003.
  • maintaining the blog is a lot easier now as I don't have to type as much as I did before.
  • my webpresence is due for a facelift above and below the skin.
  • searching the blog may be around the corner.
Well I hope that explains it.


Saturn, Mars, Venus alignment on the 21st

June 2nd, 2010

I found this article on physorg talking about the alignment. So I fired up xephem and changed the time to 10 PM on June 21st in Frankfurt, Germany and this is what the western sky at an elevation of 41 degrees looks like when zoomed in a bit.

It may make a good snapshot. Also remember that the 21st is the Summer solstice. So the date is easy to remember.


My Internet-Registration Nightmare

June 1st, 2010

So I bought windows 7. For 199 euros. How stupid of me, let me explain why. When I bought Windows 7 I also bought vmware Workstation 7 as an upgrade to Workstation 6 so that it would make use of the graphics cards accelleration. Back then I still had my Athlon 64-3500+ and graphics accelleration didn't work on it. Anyhow back then I couldn't run 64-bit vm's either and I had to install Windows 7 in a 32-bit vm. When I got my new computer that changed. I copied the vm over to it and ran it for a while with no problems. So a few days ago I installed the 64-bit version of Windows 7 and gave it the activation code and didn't notice it didn't accept it until today (4 days later). When trying to activate with my activation code repeatedly it didn't work. So then I tried to get Microsoft support and they wanted a Product-Id (PID) code from me. Their website only showed how to get it for XP, Vista but not for Windows 7 so I painfully found it and entered it and then they said it expired. So I booted the 32-bit windows 7 vm and their website blew up.. it then said the other PID expired as well. So now I'm pretty well stuck with 32 bit windows 7 (boohoo) since it's at least activated. (What do people do when their computer blows up and they have to reinstall?). If you think that was all that's nothing. When I moved my anti-virus over it disabled the anti-virus on the 32 bit windows 7 and there is no knob to turn it off and give the subscription back to the 32 bit anti-virus. So now I got a 64 bit un-activated version with a working anti-virus and a 32 bit activated version with no working anti-virus. This is a major mess in my view and I'm not to blame, I simply tried to make use of a product I paid for and switching from 32 bit to 64 bit version is as innocent as it gets. This cost my mental health, I hate Microsoft for it. And for the first time with online registrations the Internet is as useful as a dead doorknob.

New Computer, New tasks

May 26th, 2010

I totally forgot to blog about it. The computer that I "conceived" of as written below, well I got it. It cost more than I had hoped. Anyhow now I got a four core CPU and I want to put a bit of load on it. So I went back to seti@home and I'm running their windows 7 client. It's nice. I'm using all four processors in windows 7 with 25% load so it turns out about the same load as one core. I've already finished 2 workunits and I'm pretty happy.

Also notice the goldflipper image has changed. Before was ripped from somewhere and this one I drew all by myself.


Registered Goldflipper.NET

May 25th, 2010

I registered goldflipper.net which was way overdue. I had this name on my VPS in Panama for a while and never registered the domain name. Well I did now and it does provide some IPv6 glue that I never had before, which is grand.

   IP Address: 2001:A60:F000:99:0:0:0:2
   IP Address:
   Whois Server: whois.joker.com
   Referral URL: http://www.joker.com

Nothing really changes, the domain is served with wildcarddnsd and points to the VPS in Panama and the IPv6 is served from my DSL.
