I really enjoy circuits class, but…

the homeworks aren’t something you can jump into on a whim. Even Nader remarked, shaking his head, how many windows he needed open to work on the homeworks that require simulation. For those readers who haven’t experienced the joys (cough, cough) of circuit simulation, we have tools available in which we can specify a particular circuit configuration (from 1 transistor to eleventy million), and we feed it into a simulator and it will save the results into a file that we can then analyze. This tool is called Hspice, based on the SPICE simulation engine that was developed by Berkeley. The annoying part is that this is a server-side tool, which requires that we login and run these apps remotely. I’m fortunate to have an external widescreen monitor to help me keep track of it all. If you’re interested, here is a screenshot of my work environment for this homework I’m currently doing:

 

My other laptop is off to side, showing the actual homework assignment. Sigh.

 

Anyway, are any of you interested in seeing the kinds of problems I’m doing for the courses? I could do a post a week sampling what I’m currently learning/working on. Let me know what you think.

A Better than Expected Weekend

Friday’s circuits midterm was alright. It was a good exam, but I did make two stupid mistakes. It’s frustrating to lose points on easy stuff. I went to review session for the probability midterm and spent Friday night working on the take home midterm exam. I didn’t get to bed until late, and ended up waking up at around 1:30pm Saturday. There was another review session from 2 to 4 where the TA went over the solutions for the practice midterm, which was helpful. Why am I so concerned about this midterm? I don’t think I have had such a poor grasp of the subject matter before. In circuits, there are physical behaviors — I can ask myself “what would an electron do?”. With probability, I often have no idea how to setup the problem. I spent the rest of the day going over old homeworks. After the 2nd cup of coffee at 7pm, decided to gun it and kept working through the night. Did laundry at 3am. Made it until about 8am, when I took a 2 hour nap that turned into a 4 hour nap. Did some grocery shopping with Luke. Spent a while cooking chili and dal makhni for the upcoming week. Luke was filming a video for his research project. Later that night we watched the finale to the the South Park story arc ‘Imaginationland’, thoroughly enjoying it.

It sucks that Indy lost to the Patriots. NC State beat Miami in OT, crossing my fingers for this week’s game against Carolina. Stanford lost to Washington. Did a lot of thinking about the Krispy Kreme Challenge too, with frequent discussion with Thomas Finch, Greg, and Kelly. Thomas has been really good about learning from the experience Greg and I have had doing this race for 3 years and our knowledge of the web. It’s worrisome to me that the other four members of the organizing committee aren’t doing the same. The room for error when an event starts to involve more than 2000 people decreases very rapidly. Hopefully this conference call on Tuesday will be give me more confidence.

My parents finally arrived in Mumbai after being delayed 4 hours in Raleigh and another 4 hours in NYC. Fortunately it was a direct flight from New York to Mumbai, but two of their bags are missing. They’ll be arriving in Akola, the small town in central India where my Dad was born. This is a photo I took in 2004 of the building where he spent most of his young childhood.

Where Dad Grew Up

Donny seems to be settling very well to the east in Bangladesh, making me feel embarrassed cause he’s schooling me in a South Asian language despite me having a huge advantage. Looks like Greg was Extra Number 7 in a commercial that Siemens shot at Cambridge (maybe Donny too gets to be in a commercial?) I wanna see those on YouTube.

What’s coming up next? After midterms are over, we’ve got one more hw in circuits (due this friday) and then our Project will be assigned. I’m staying here over Thanksgiving and will be working on it full time. Looking forward to it…that class is great.

Crunch time – a lot happening

Got my 278 homework done…sort of. Circuits midterm rapidly approaching (Friday morning). Still need to study for that. My parents are leaving for India on Friday too. The big dinner I made for Mary and Matt on Sunday? I just finished the leftovers today….

I had lunch with Ed Chiang today, who went to high school with Donny. We had been meaning to meet up before classes started, but never got around to it until now. Had a two hour lunch with him at Bytes. Really good guy, fun to talk to. He’s doing a Master’s in EE, in more of the computer architecture/software side.

Earlier this week I worked on the UV LED project, the Lunar X project, some KKC stuff, and talking a lot with Mike. It’s fun though. I totally agree with what my friend Lei observed: coursework keeps me from doing what’s really important. I think he and I will take a break from studying for our 278 midterm (upcoming Tuesday…i don’t think i’ve ever been less prepared for a midterm ever) and watch some football. Poor guy hasn’t seen a full game since the season started…and he’s an Ohio State alum.
