Very cool presentation by Agarwal

March 27th, 2016

I've been watching this guys science for a while. It intrigues me and my dreams are shaped around the topic of photonic computers. I want to show you the latest presentation I've seen from him:

If only I were smart enough to build me one computer such as that, but to be truthful there is a lot of researchers worldwide trying to make this happen, so why would I succeed? lol.


Spring now...

March 21st, 2016

Well it's spring now. The equinox came and went and I didn't even blog about it. However I did find a tweet by Dr. Neil deGrasse Tyson, that said that because of refraction of light the equinox actually has more daylight than night and it's not "equal day/night", but without this refraction of light there would be exactly the same time for night and day. Anyhow I found the tweet worth blogging about.


Making a turn-key dns server out of DelphinusDNSD

March 19th, 2016

Freifunk Franken needed a turn-key server to convert a MAC address to an AAAA RR via DNS, so I fleshed out (stripped out) a lot of parts from delphinusdnsd and made it available to them ( FFFdnsd.tgz). The code to this is open source. Most of the functionality is that I put together last night is in lookup_zone() which creates a struct domain on the fly. There is some inefficiencies on how the code is right now, but it works and that's the main point.

We discussed a little about buffer overflows, but I'm thinking if I introduced anything bad in lookup_zone() then that's where to find those. The rest of the code is identical to the delphinusdnsd code base (which also runs in production). I'm glad to be of use with my 10 year old daemon. It's not every day that I get a request such as this one.


Lordy Lordy look who is Forty

March 14th, 2016

In a few days I'm turning age forty. Time really went by fast. I'll be updating my private section of my webpage very soon to reflect this.


30 Years of Personal Computing History

March 6th, 2016

I have updated my chart of all computers I have ever bought (except the RPI) that I last left in this article. Had I an accumulated computer of all clockcycles and RAM my computer today would be a single core 50 GHz computer with nearly 100 GB of RAM. Wow! However I don't have all the computers anymore so it's less than that in reality. Here is the updated chart...

Let's see a "computer generation" is 1.5 years and 4 years have passed did 3 generations after doubling each generation hold true for me?
generation 1 - 36
generation 2 - 72
generation 3 - 144

So judging by this I should be buying a 64 GB RAM machine at mid year in 2016. (In order to stay true to Moores law...) Sorry that's not gonna happen, I plan on keeping at a bit of a standstill until 2020. But since this will be another generation past, I'll be expected to get a 256 GB RAM machine or so (by 2020). Wow! I do hope I find a use for it, but with Virtual Reality on the horizon I'm sure there will be.


After 16 years, I got a TV

March 6th, 2016

I finally got a TV after 16 years. It's a 48" Samsung and just blows my mind. I also bought a few other things with it. Now it's almost time to save up money again. I'm feeling really lucky though. It's great to be having money to spend and make use of these things. Thanks to a job!


Ordered a backup Firewall

March 3rd, 2016

I have ordered a backup APU firewall. I'll keep this around in case the one I use now breaks. Having venus break was a wakeup call for me. Basically I can't afford to lose gamma my main firewall, or have a backup for it. I chose the latter. I wouldn't need this if I didn't work from home, btw. Looking in my chart logically this backup firewall will be called "delta".


New VDSL modem turned on

March 1st, 2016

I have turned on this new VDSL2 modem that I got the other day. Here is the link stats from my current ADSL.

I'm slowly getting ready to get a new provider (one that offers VDSL2 with vectoring) giving me 100 Mbit/40 Mbit. I'm just waiting for the venus soekris board to be returned to me with whatever fixes, and then I'm initiating a switch.


19 days until March Equinox

March 1st, 2016

Happy March. We'll see the transition from winter to summer in this month at least officially as a number because the equinox is officially the markation point at which spring starts and winter ends. Can't wait!


New Access Point in my apartment

February 24th, 2016

I have bought and installed an ASUS EA-AC87 Wireless AC1800 access point in place of my Fritzbox. It took some nerves to configure my repeaters to it but now everythign is functioning. Just too bad the soekris died. I'm monitoring the health of this wireless access point but so far so good. I can't do test scp's to see how much faster everything is becuaes I lost the soekris/venus and will have to wait until it's replaced.
