Why computers?

May 27, 2012

A new book has come out describing why some women do get into computers and how information is useful to getting more women in the field. That made me think about how I got here.

Two factors started me on the path to a career in computing: education and opportunity.

Given an affinity for math and science, I went to a small college with the plan to get an general engineering degree and then build underwater cities. I’d taken calculus in high school (a giant school where very few graduates went to college). In my freshman year in college, I was taking the college level calculus and acing derivatives. But then we got to this flattened S symbol that I had never seen.

Physics, chemistry, even biology and psychology, were all much harder until I learned integration (and I never gained the same level of confidence). But intro to computer science? That was blissfully easy compared every other class I was taking: I could understand it just by thinking like an idiot (and I felt like an idiot a lot given the math situation).

I know computers aren’t easy for everyone. I don’t know if they would have been easy for me if I hadn’t been doing so poorly in everything else. But I was so computers were comparatively simple and a welcome refuge.

Anyway, around the end of the semester, since I’d done well in intro CS, I was able to take a work study job as a student consultant to the CS department, helping the system admins by answering common questions and leaving the serious problems to the CS staff members (juniors and seniors doing work study). I stayed with it, eventually becoming part of the admin staff and learning to take care of a variety of unix systems (and manage the front-line question-answering consultants).

I kept going back to systems engineering (how can I hate integration but love Fourier?). However, CS jobs were more prevalent, particularly given my shiny new resume with experience of sys admin and some odd programming jobs for math and chem professors. The systems engineering math has been awesome for embedded software (motor control and signal processing!) so I got what I needed, more than I expected, much more than I knew to ask for.

I’d still love to work on underwater cities. But I bet they’d have microprocessors so I’m good.

Where to from here?

May 22, 2012

Hmm… well, we made it through the trip. I have trouble saying it was vacation. And I have trouble saying it was wonderful. I tend to say “time off”, “trip”, and “cross country road trip”. For adjectives, it is “cool”, “educational”, “interesting”, and “epic”. Overall, I had a good time. But I don’t know that I’d do it again this decade.

But this blog, what is going to happen with it? Well, I want to have someplace bigger than twitter to write things. What things? Sheesh, stop pushing… I’m not sure. I’d like to write some technical things, maybe how to do some embedded systems things but I don’t really want to put too much code in. I’d kinda like to keep it accessible to friends and family (most of whom skipped over that gadgets and time post a few weeks back).

Let’s see… I’d like to explain to Emma what an algorithm is and why it isn’t something she should ever have worried about asking about (short answer: a recipe; long answer: forthcoming post). I’d like to bemoan the fact that my amazingly talented flute-playing sister-in-law didn’t know what Excel (or Numbers) was and then generally explain how a spreadsheet will make her new career much, much easier. (How can your run a small business without a spreadsheet? Playing music is definitely a small business.) I’d like to write more about my book (I got new reviews! Reviews are scary… And I just put an ad on a web site, also oddly nerve-wracking). I want to help Luckshman with his new-to-firmware where-do-I-even-start questions. I’m planning a post about spam-comments. I still have some trip related things to write about based on the questions I get (which cities were the best?). There are some gadgets to review… and maybe some books.

That is all pretty unfocused. That is ok. Remember, it is about the journey here. Wandering around in circles is ok as long as each circumnavigation is interesting.

The posts may be slower but I’m not done here.

More about George

May 17, 2012

George was a good pet. He ate a lot but took us all over. Here is George, munching.

C and I spent a lot of time in him. Let’s just say it was about 100 hours (7102 miles, we didn’t go 90mph always… there was the occasional construction and some traffic and that hideous 40 minute drive to go 4 miles in Boston).

This is what C looked like for most of that time. (Though this is Donner Pass, toward the end of the trip.)

I did drive some but taking pictures while I drive is dangerous. I planned to get some bloggin done in the car, maybe even some work (I still haven’t started the article due this month or the blog-article due last month, sigh). Thus, this is what I planned to look like:
Actually, though, I mostly stared out the window. That was one of the reasons I tried so hard in the never ending battle against bugs on the window. Even the side windows got gunky eventually; they were still clear in Memphis.

George had a decent sound system so we listened to music and books. He also heated seats (really only useful in Boston) and separate driver/passenger temperature controls (normally set to the same temperature but the first twenty minutes of being in the car were always different so separate controls is a new high-want feature for future cars). We normally put the back seats down but left the front seats up, filled with backpacks, jackets, shoes, small ice chest, snack bag, trash bag, and box of kleenex.

When we had our brother- and sister-in-law in Boston and their travel cases (larger than ours though they were only in Boston for a weekend, I will be teasing someone about that), it was a tight squeeze. But we did all fit ok, probably could have fit one more (small) person (but not their luggage).

We could have slept in George but we never needed to. It was nice to have the backup option. I don’t think we could have slept *comfortably* but that is ok, it was like backup plan S.

With 17 mpg city and 24 mpg highway, George could have been slightly hungrier. Or we could have driven slower to get the highway number more consistently. It is a far cry from our normal Prius milage. Actually, going back to the Prius has been a bit jarring. It is more than ten years old and while a decent non-luxurious car, it doesn’t have much pickup (comparatively, no acceleration) and the cloth seats feel cheap. Of course, it is dusty and needs a tune up (two lights on the dash are on!). And it doesn’t even have a name. Sad.

Missed work

May 17, 2012

When my husband occasionally declares it is going to be an Internet-free weekend, I know this means he’ll be asking me for all the news and weather and general ‘net hijinks. I don’t participate in the disconnecting. I like to believe it is because I’m not as addicted to the web.

When we go on vacation, I usually monitor email from my phone. Working for myself, it is fairly important that I don’t piss off clients. Even if they know I’m out of the office, their problems are (of course) super high priority. (My eyes rolled just typing that.) But I will admit that I like to feel needed.

I remember in 1999, when I worked at HP, having it be almost noon and I hadn’t gotten any email. It was surprising. I’d gotten a lot of work done but at some point started to wonder if something was broken. I checked my Ethernet cable (remember those? someday no one will believe us that they even existed), I surfed the web to make sure it was still there. But everything worked. I wailed in my cubicle that no one loved me. After lunch, there were several messages waiting and I felt much better.

This is an enduring and ingrained feeling. Getting a ton of email while I’m out of the office indicates a lack of preparedness on my part. But getting one or two? Well, that’s just love.

On my recent extended vacation, I monitored my email, ignoring lists and focusing on the few things addressed to me. It boiled down to two job inquiries, a dozen emails from friends trying to set up lunches or checking on my progress, and about a half dozen work things almost all starting with “if you have a minute, could you tell me how to…”.

I didn’t miss email while I was gone. And if I had, the hundreds of emails that I didn’t read would have cured that (lists mostly but they usually have a kernel of something I need or I’d unsubscribe).

However, while I didn’t fully realized it until I got going again, I missed working. I missed fixing things. I missed typing a line in and seeing if it made things better. I missed the puzzle of figuring out which steps are important and which are voodoo. I missed finding ways of explaining complex ideas in a simple matter so the team could discuss them more easily. I missed getting things done.

This is what I’m good at. I’m glad to be back.

So how many states did you go to?

May 16, 2012

I had lunch with a good friend today who asked how many states we went to on this trip. I was embarrassed that I didn’t know. So here is the list (in order of appearance):

  1. California
  2. Arizona
  3. New Mexico
  4. Texas
  5. Oklahoma
  6. Arkansas
  7. Tennessee
  8. Virginia
  9. Washington DC
  10. Maryland
  11. Delaware
  12. New Jersey
  13. New York
  14. Connecticut
  15. Massachusetts
  16. Pennsylvania
  17. Ohio
  18. Indiana
  19. Michigan
  20. Illinois
  21. Wisconsin
  22. Minneapolis
  23. North Dakota
  24. Montana
  25. Wyoming
  26. Idaho
  27. Nevada

So 26 or 27 depending on whether DC counts as a state. All that in 22 days. Lucky those eastern ones are small.

Let’s look at it graphically. These are the states I’d been to before:

Hawaii and Alaska are not shown. I’ve neither been to them nor managed to make them part of this driving adventure.

These are the states on the trip:

Yeah, we could totally have crossed tiny Rhode Island off but it seemed like driving 5 miles and touching ground then going back was somehow cheating. (Michigan, you be quiet. We got snacks on our jaunt to you.)

Combined to show all the states I’ve visited now:

(Maps were created using this excellent generator.)

And now, when one of my super-traveling buddies expects me to say I’m going to Santa Cruz or Napa Valley for my summer vacation (it’s been known to happen), well, “HAH!” I will tell them. And then I’ll go get a drink and sit by the ocean.)
