Getting a terminal IBM Model M to work with PS/2

 I recently bought another IBM Model M (1395660) on eBay the other day, not thinking that it is actually a terminal keyboard. I thought it has a detachable SDL cable like my current Model M (1391401). I was wrong. Turns out it has a non-removable RJ-45 plug instead, thus being a terminal keyboard. Well, aftering some researching, some were able to get it to work by using an ATMega. I was able to find a pinout of the RJ45 plug on the keyboard, and simply just wire it up to a PS/2 cable. Though apparently, the colour of wire for PS/2 is not standardized, which led to testing each pin to see what it does. I cannibalized an old Microsoft keyboard for the cable and was able to hook the wires up straight to each other.

DeLicate Linux, still usable at 166Mhz

Linux, one way or another, really brings out your inner hacker. I've been tinkering quite a bit with DeLicate Linux. It's a lightweight distro made for old computers that uses the 2.4 kernel. Right now, I have DeLicate running on a Pentium 166 with 64MB of RAM. Surprisingly, Fluxbox and Xchat run without any huge problems. Replacing Bash with Dash helped free up some RAM as well. DeLicate uses pacman as the package manager, so building new packages is as easy as creating a PKGBUILD file.

External antennas on ASUS EeePC 701

I finally did what I always wanted to do: add external antennas to my 701. Drilling the holes were a bitch. First, I tried at the right hinge, but the end of the RP-SMA connector was too large. Then next to the VGA port and no luck, Oh, but perhaps next to the second USB port on the right hand side? Nope. Well, what I ended up doing was putting the connector on the outside. Check out the picture:

Thanks Nyko, now I have an unusable Xbox!

A little while ago, I wrapped my 360 in a  wood Oblivion Xbox 360 skin. Lately, I've been getting more RROD's than usual. I'd be in the midst of a game and it'd shut off with three red flashing red rings. I've had the Nyko Intercooler on my Xbox for the last couple years and, I thought, would make the RROD problem go away. Apparently not. So today, I took off the Intercooler.

Dual Xeon build

I've had these Xeon processors sitting around for a while now and I thought it's about time to get a motherboard for them. Two are clocked at 3.0Ghz/1MB/800, other two are at 2.8Ghz/512/533. I ordered a Super Micro X6DVL-EG2  from eBay for $120 of which I seen this motherboard up to $250. Anyway, came the other day and finally put it together. Heatsinks didn't screw into the case as it should, so I had to screw the nut right onto the heatsink. 

Schematics

I've been profoundly confused on what to do with two new servers. At the moment, I have a total of three servers; a BitTorrent tracker, web server and NAS (NFS server). Now, what I was thinking was setting up a load balancing scheme using VS via NAT. Essentially, build one of the servers as a load balancer and turn the other one into a http node. The only problem with that is redundancy. Say if the load balancer fails for whatever reason, I'm screwed.
 

Web, log and mail server.

Thought I'd take it upon myself to create a mail server on 'roppie' (me server). It's now a log server also, I even got my router to send logs to it too. Interesting it is though, I have 'jlap' sending all its logs to roppie too. 'roppie' also runs a minimal web server (lighttpd + mysql, same as jlap) but also serves the logs out on HTTP so I can view them anywhere.
