I posted the pictures I took of the IRT City Hall station. The tour was given by the New York City Transit Museum on March 15, 2008.
I’ll have to touch up the pictures at some point, most of them are really dark (the station’s lighting isn’t the best).
Deferred maintenance isn’t a good thing. Upgraded Wordpress to 2.5.1. Please tell me if anything is broken.
I’ll try to post a little more often, but not tonight because it’s time for bed.
I was just given a Mac Plus (with 4 MB RAM, it’s max). It currently has a 20 MB external disk. Would anyone be willing to give up a bigger disk (I’d really like 40 MB; it’s external 25 pin SCSI) or System 7 install disk so I could really trick this box out?
It’s been a while since I last updated, which I think is because I started a full time job (as a Sys Admin at Rutgers) and I’m finishing up my last two classes of my undergraduate career (yes, it’s take long than I wanted). I think it’s also because I use twitter, which is a nice way of putting down random comnent instead of a full blow post that tends to get long winded to fill out space. I put a feed of my twitter thing on the left. Feel free to follow me if you want.
Anyway, I’ve managed to purchase a Sun Blade 2000 (specs are in the Systems tab), which has become my main desktopy workstation (I think I’m a sucker for the glowing Sun logo on the front). (Yeah, I know I could get a better x86 machine, but I don’t want to)
Erlang has once again has come up and peaked my interest. I got the Joe Armstrong book a few weeks ago and managed to compile erlang for Solaris/SPARC today (I’ve had it working on my iBook for a while now, but the previously mentioned Blade 2000 is a much nice machine to program on (read: it’s got a big screen)). If you need it for Solaris 10/SPARC, send me a message.
If anyone needs a SCSI CD drive with 512 byte blocks, I have two (maybe three) spare XM-4101B (those are the 1″ drives found the in the SPARCstation 4, 5 and 20). Price of shipping is all I ask (of course, you can always just meet up with me).

To some, this may seem stupid, but I must say, it’s the small things that count and make a product really nice.
If you even considered doing a network Solaris install, you know the docs tell you to use Solaris’ DHCP daemon. For lack of better words, it’s kind of crappy (it might be powerfull but it’s way to complex if you are just doing a simple setup). I’ve found a couple sites with information on how to use ISC’s DHCP server:

This weekend, I went to Washington State to visit/help Marla. This was the first time I’ve ever flown without someone I knew. Even though I’m an engineering student and have taken classes where all this stuff is explained, it still amazes me that this stuff actually works.
I got the Digikey order mentioned in the previous post last Friday, and put together the USBtinyISP today. I would highly recommend this programmer for anyone starting out. Not only does the kit give you some experience with building things, it’s about $15 cheaper than the avrisp2 programmer (get some micros with that $15). I managed to get avrdude going and programmed a ATtiny2313 with a precompiled blinky LED program. I got it working after realizing some stupid mistakes I made. Now I’m watching a LED blink. I don’t know who said it first, but there is no other time that would make a person so excited to see and LED blink.
Not really much interesting is going on Just thought I’d update on a few things since people have been asking for it.
I bought the USBtinyISP. It’s a cheap AVR microcontroller programmer (sold as a kit). I already have (more expensive) PIC programmer, but the AVR seem better with the availability of avr-gcc, avr-libc and avrdude (interfaces with the hardware programmer). Having to do any thing with PIC using free software always seems like a pain in the ass (like I can’t find mac or linux software for the programmer I have). Anyway, the AVR assembly seems more to my liking (on the rare occasion that I do some). I haven’t made the LED blink yet as I still need parts (a Digikey order was made the other day), but hopefully next week.
While on the topic of hardware, I wanted to built a cheap kit radio so I could try some homebrew QRP. People have recommended the SW+ 40, along with a few others. I was just wondering if there was any other recommendations? Also, any opinions on the Norcal keyer or any set of paddles?
