During my undergrad and masters, I worked for Chris Edwards, who took over the IC engine lab from Fritz. It was a fun place to be -- running a single-cylinder research engine and a chevy LS1 on the dynos, setting up a miniature turbine eng

Just made a reminder note to do so! As it turns out, you’re squarely in my target audience, as “a software person with hardware ambitions.” :D Will keep you posted.

I’m keeping a journal as I go thru the class that I plan to publish at some point. I’ve just gotten to some meaty parts and I can say I’m impressed, but you’re right, I’m not a success story (yet). We will see!

I'm taking 30x500 from Amy Hoy and Alex Hillman. They are in patio11's orbit. It's an expensive class and would only be worth it if you are really willing to commit. They have some other less expensive products (Year of Hu

I always do integrator wind-up similar to how you do it -- apply limits to the overall controller output (which are typically necessary for the system anyway), and use that to limit the integrator. Just putting limits on the integrator is

My favorite book of all time, bar none. Adventure, bravery, friendship, loyalty, love, life, and death. Written with a vividness and tenderness that brought me to tears. It sounds trite, but it's so true. If you haven't read i

If you are doing hobby side projects that are solely for learning, then this article's advice is (mostly) not intended for you. If your goal is to explore new tech, try new approaches, go down rabbit holes, then by all means, go for

A bit OT: does anyone have recommendations for textbooks or other resources that teach basic military strategy and tactics? Whenever any military discussion comes up that even touches technical aspects, I feel pretty lost. Similar to how

My company uses a C++ subset (no STL, no malloc) on all of our embedded projects, which are mostly on ARM Cortex-M4. I'd love to learn and start using Rust in our work, but we are client-project-driven, so it will be hard to justify th

Has anyone here worked in a laboratory or other environment that uses these reference masses and requires this level of precision?

(Very) Long term, it will be interesting to see what happens when everyone is carrying Google Babelfish around with them.

She scans it in a scanner, but the music is often in large books that don't lay completely flat, so you still see the warping near the binding.

Thanks for the suggestion! I'll check it out.

This is great! My wife is a music teacher and often scans sheet music so that it's more portable. She has been asking me for a while for something exactly like this. I'll have to tweak it to work on sheet music, since I imagine

Sure, the board may rarely actually hold a vote on a given direction, but their ability to vote to remove the CEO is a huge threat hanging over the CEO. If a majority of the board favors a certain direction, even if they don't hold a

At 1.5% ownership, YC has no say over the direction of the company (other than through the influence they have from being well-known and respected in the startup space). The conflict arises when your VCs sit on, or even control, your board

"... In fact, this is already happening, in part because programmers increasingly rely on 'self-correcting' code—that is, code that debugs and rewrites itself ..." What on earth is the author talking about? I've ne

Not disputing the likelihood of pilot error, but note that the pilot had nearly 3000 hours of flight time. From the linked Oklahoma 6 story: "The NTSB says Inhofe [the pilot] had a total of 2,874 flight hours, with more than half of

I do know list comprehensions, and I use them all the time (not trying to be defensive here, just providing context). I understand that they are just a different syntax for mapping -- applying a function to members of a list to produce a

I am. I know python quite well, but I did not understand functional programming before I read this article. Oh sure, I'd looked it up on wikipedia, and read a few blog posts, and perused a Haskell tutorial, but none of that made it c

This is indeed a non-educated opinion. Please don't spread FUD. Lithium-ion batteries are perfectly safe to regen. You need to monitor the cell and pack voltages and limit regen under certain conditions, but it's well understood

You got that right. I tried RC heli flying for a little bit. Spent several hours flying in the sim and several more flying the real thing, and could never comfortably do a nose-in hover. Very humbling. These professional RC hell pilots

Solution: "They're a stable, growing business that is profitable and intends to be in business for themselves for a long time! Not as risky!" Not under the control of the customer, obviously.

I referenced this video in a discussion the other day about the Conada effect and how wings work [1], and I thought the video was so good it merited its own thread. Feynman gives a supremely insightful answer to a superficially simple ques

Which is exactly my point. You: "But that doesn't answer the question. WHY does the air get pushed down?" They: "Because of such-and-such effect..." You: "But that doesn't answer the question. WHY does s

I think that this topic is a classic example of people trying to answer the problem at different levels of abstraction. There is a famous clip of an interview with Richard Feynman where he cannot give a simple answer to "Why do magnet

I suppose I didn't do much research before posting my original comment. I should have known that there would be plenty of resources out there.
