Ask Slashdot: What Do You Wish You'd Known Starting Out As a Programmer?

DudeTheMath Re:How to write code (470 comments)

Oh, yeah, that "someone smarter than you" is often future you! OTOH, I also get to look at the occasional bit of code I wrote ten years ago and think, "Well done, young padawan" (although maybe that means I haven't learned enough yet to know a better way).

Ask Slashdot: What Do You Wish You'd Known Starting Out As a Programmer?

DudeTheMath How to write code (470 comments)

Write like someone smarter than you will have to fix it ("Who wrote this crap? At least I can tell why he or she did that."), and like someone dumber than you will be adding features ("Bless him or her for making this easy."). You'll be both eventually.

Of the following, I'd rather play ...

DudeTheMath Re:Chess (273 comments)

I played a lot of bridge in college & grad school, but then only read about clubs playing in the middle of the day. Just six weeks ago, I found a local club that has evening games, and I'm getting back into the groove after two decades of playing only bad contract bridge every other year when Christmas was at my parents' house.

Check for local bridge clubs where you are; they love to have younger players, and most are happy to accommodate singletons until they find a regular partner.

Researchers Print Electronic Memory On Paper

DudeTheMath Re:Density (78 comments)

Yeah, I was bothered by that, too. 8.5x11 paper is 603.22 cm^2, so we can fit roughly 6032200 100 micron^2 on the sheet, or about 736KB. Now, if it's really 75 microns on a side, the density goes up by 16/9 to 1309KB. Maybe they're leaving a margin? TFA gives the "100 micron" and "1MB" values, so it's not the poster but probably the reporter who made the mistake.

IRS Recycled Lerner Hard Drive

Survey: 56 Percent of US Developers Expect To Become Millionaires

DudeTheMath Re:How is this remarkable? (467 comments)

This is pretty much what I was going to say. The other 44% apparently either can't live within their means or can't do the math of simple compound interest.

I'm not even a particularly well-paid developer, and my wife and I are about 80% of the way there (in our retirement accounts) after not quite twenty years of saving.

U.S. Biomedical Research 'Unsustainable' Prominent Researchers Warn

DudeTheMath Re:No shit, Sherlock (135 comments)

Perhaps it is not just the scientists, but the university administrators and those (legislators, for state schools) who hold the purse strings, who believe that the only credible source of research funding must be the federal government. Then they look at the humanities faculty and ask, "Why aren't you paying for your own research with federal grants? It must not be of benefit to anyone."

Do We Really Have a Shortage of STEM Workers?

DudeTheMath Re:The difference in the two numbers ... (491 comments)

My employer simply has a six-month training wage (with a 50% raise to "normal" after the training period). Either you get what we do in those six months, or you really never will, but he has absolutely no problem with on-the-job training.

Do We Really Have a Shortage of STEM Workers?

DudeTheMath Re:Define "qualified" (491 comments)

This (no mod points today). I'm a dynamite C programmer, some small experience in JS & C#, and I know how to design an rdb schema and write a stored procedure, but I don't have "4 years experience with jdb and Netbeans". Whatevs: give me three weeks with actual stuff to do, and you probably couldn't tell the difference, but it's darned hard to get hired.

Are Bankers Paid Too Much? Are Technology CEOs?

DudeTheMath Re:Fair v. Equitable: Who cares? (712 comments)

Note that the CEO is trying to get the most out of his (almost always "his") employer, too. Who's his employer? Why, the board, usually full of banking CEOs who love to negotiate their high salaries, bonuses, etc., from their boards. It's largely a big circle jerk.

Who Is Liable When a Self-Driving Car Crashes?

DudeTheMath Re:laws change (937 comments)

Who could have envisioned, 50 years ago, that we would have cars that drove themselves?

Isaac Asimov, for one, and I'm sure he wasn't the only one, just the one that's been, y'know, all over the news this week.

EV Owner Arrested Over 5 Cents Worth of Electricity From School's Outlet

DudeTheMath Re:Henchman (1010 comments)

Where does this happen? I had a weekly commute across southern Michigan on US 12. Every eight to ten miles, there was another town, and the road widened from two to four lanes, allowing easy passing of anyone I'd been "stuck" behind. I always calculated my time savings (miles to the next town, desired speed, current speed) from a pass before I even checked for oncoming traffic. It did wonders for my blood pressure. I saw way too many people trying over and over, and occasionally making a really risky choice, to pass someone who was doing 53 in a 55 when there were only a couple of miles to the next town. So I'm making this suggestion only that one think before acting. If you can pass safely, by all means, do so. I'm not going to hold you up.

Also, reflecting my status as a former math teacher, I adjusted the numbers to reflect freeway driving and to get a "nice" answer; I read once that the average freeway commute was about eight miles.

Ask Slashdot: Why Are Tech Job Requirements So Specific?

DudeTheMath Re: To hire specific people (465 comments)

No he doesn't; the "You insensitive clod" is just a form of address (in Latin, we'd call it the vocative case), like "Dave, I thought I was a shoo-in for that job." His error was using "shoe-in" where he meant "shoo-in."

How Safe Is Cycling?

DudeTheMath Re:Please (947 comments)

I wish I could cite the study where I learned the overtaking statistic (I probably found it on the WashCycle blog), but the results were certainly consistent with my own experience. I've been buzzed, and once been bumped by a panel truck that probably thought it had completed its pass (although I was barely bruised), but I've never been hit from behind. It's the left cross that gets me every time. I have stopped signaling right turns when there's oncoming traffic waiting to turn left into the same street, because it seems as soon as they see my signal, they think they can beat me (I'm assuming they see me at all, of course), and keeping both hands on the bars gives me more control whatever they do.

How Safe Is Cycling?

DudeTheMath Re:Please (947 comments)

Thanks for the critical eye on this. And, as I said, overtaking is the kind of interaction I'm least worried about, so it has very little bearing on my decision to wear a helmet. The risk (chance of the helmet making a difference) may be very low, but the reward in those few cases so high, that it's worth the minimal cost. The only times I've regretted wearing a helmet were on sixty-mile-plus rides where I could hardly keep my head up by the end due to neck fatigue.

How Safe Is Cycling?

DudeTheMath Re:Please (947 comments)

Slows them down? Really? They can dismount it for the crit, right?

We already do the bright colors (I got jerseys in fluorescent green, fluorescent orange, fluorescent yellow, snow-blind white, and BSOD blue), but it just never occurred to me to have a flag. How 'bout I spray-paint a raccoon tail traffic-cone orange? Awesome.

How Safe Is Cycling?

DudeTheMath Re:Please (947 comments)

One study has shown that cars overtaking and passing leave more room for cyclists not wearing helmets. However, being struck from behind is about the least likely kind of car-bike interaction (cars turning across a cyclist's path vastly predominates those statistics).

My wife is (likely) alive today due to her helmet (that is, she is alive, but likely wouldn't be but for the helmet). She left a helmet-shaped hole in the windshield of a driver who t-boned her while illegally driving in the shoulder.

I may never need my helmet, but I always wear it (well, almost; when I borrow hotel bikes in Europe, I don't bother).

Fruit Flies are Better Than You at Calculus

DudeTheMath DudeTheMath writes  |  about 5 months ago

DudeTheMath (522264) writes "Cornell University scientists studied how fruit flies respond to flight disturbances (instead of wind gusts, they used carefully controlled magnetic pulses) and found that the flies recover in as little as three wing beats (at 250 per second) by doing some kind of calculus in a little "integrated circuit" of neurons that control the wings directly. The pitch and yaw results are already published, and the roll study is forthcoming. (NYT, partial paywall, autoplay of fly that starts with a car ad.)"

Home testing for solar roof coverage?

DudeTheMath DudeTheMath writes  |  more than 2 years ago

DudeTheMath (522264) writes "Here in the Sunshine State (FL), solar should be a no-brainer. However, large oaks that require permits to trim partially shade my roof. I'd like to (inexpensively) "pre-qualify" my roof for effective panel area. Googling for "home solar testing" gets me equipment for checking the efficiency of an existing PV installation.

Do any makers know what I can do on my own in terms of placing a few individual cells and, over a year, measuring and recording their output, so I can get an idea whether solar would be cost-effective for me?"
