Sure, the cost-function can certainly be multi-dimensional.

Energy, pain, maybe even expected value of death (e.g., take energy-intensive and possibly painful evasive action from a predator) might be dimensions to take into consideration.

Quite interesting article. After graduating from a control-theory-heavy program, I have started thinking about animal movement as an optimization problem. A manipulator is moved into a desired position while minimizing the cost function of pain, in order to avoid damage to the body.

That would fall in the "useful painful pain" category, I guess.

The Art of Electronics.

I can't say I've read it cover-to-cover, but it really is an excellent, approachable electronics resource for enthusiasts and professionals alike.

I had a similar experience.

Reading secondary literature gave me some context about Pirsig's own mental illness and his struggles overcoming his son's death, but in the end I was still disappointed.

Edit: Also, it's not about motorcycles at all. If you are interested in motorcycle travel, read Ted Simon's Jupiter's Travels instead.

All videos on this channel are worth watching. Interestingly enough, this one and another of my favourite channels [1] are run by Formlabs employees. It seems like they have some excellent engineers working for them.

You s.o.a.b., I'm in.

Lite is written by rxi, who has made some excellent game jams with very impressive youtube videos showing him doing programming, artwork and sound effects, all at record time [1]. His other github repos are also excellent, for example fe, a minimal Lisp, is definitely worth checking out.

A company that hires him signals that it has nothing to hide, so I think this might just work out fine for him.

Their distribution method for Ubuntu is a bit unfortunate, I'm not sure I will install another package manager (flatpak?), give it root access, and then trust an unknown source (flathub?) just to try a software.

I have played with LibrePCB before and the user experience is excellent. The file format is also interesting, a lisp-style, human readable text file that can be version-controlled and in some cases compared against other schematics. I also suspect that generating netlists from code (similar to SKIDL for KiCAD) would be quite doable.

My main issue were libraries, even though making footprints is easy enough. Is there a way to import the KiCAD standard library with footprints and symbols here? It would be amazing to have a large, CAD-agnostic component library!

I briefly worked for a competitor of Ampyx.

I love the idea, but given that it took decades to scale traditional wind turbines which are much simpler by design to powers in the range of MW, I can't see this happening.

These systems are insanely complex, you need tethers, winches, a drone that flies 24/7 and can safely and autonomously start and land in many weather conditions. It also looks like google gave up on Makani, which had airborne generators.

Looks like he used Ardour [1] and Guitarix [2].

I am curious about the latency of this setup, having used jack and Ardour in the past for recording. I would be very surprised if this rig yields a latency below a couple dozen milliseconds, which, at least for me, is absolutely unbearable when playing guitar.

Even with a dedicated DSP, effects processors in the early 2000's (like the otherwise excellent Vox TonelabSE) greatly struggled with latency issues.

This. I can't believe how much time is lost in such discussions. To paraphrase cjbprime from 11 months ago [1], "nobody likes what the code-formatter does to their code, but everybody likes what it does to their coworker's."

Ah, measures of angle. One of my favourite is the Warsaw Pact Millirad, of which there are 6000 in a full circle, a full 6.25% less than the 6400 NATO mils.

The economical impact of COVID-19 on people's lives will be far more severe than the biological one.

Hopefully this won't discourage governments from taking appropriate action once a more lethal pandemic comes.

Cockos is the company that also develops Reaper, which is probably the best audio production software out there.

Just signed up as a local maker, it is nice that they are trying to connect hospitals with manufacturing capabilities [1].

Good advice. I also recommend to make sure the toolchain is usable and documentation is readily available.

I worked on a project that had an Silicon Labs EFR32, and while the hardware may have been great, their proprietary, closed-source "Radio Abstraction Interface Layer" was hard to use and badly documented.

The Eclipse based IDE that you HAD to use to configure the radio front-end (the EFR32 is a system-on-chip with an RF front-end and an ARM Cortex M4F core) is a GUI, and porting or comparing radio configs between different chip generations, and even different versions of the IDE, is a nightmare.

The Java IDE crashes regularly, debugging does not really work etc., so it really is worth taking some time to evaluate the whole package around an RF IC.

"I basically ran my Benbox CNC 1310 (almost) nonstop for multiple weeks."

Wow. That's some serious dedication. What an excellent multi-disciplinary project, congratulations!

These are artistic 3D models of different parts of a fictional miniature nuclear reactor, right? Am I missing something here?

If anyone is interested, here is the source code for speeduino [1], megaSquirt [2] and rusEFI [3], two comparable open source ECUs.

Very interesting. It reminds me of Love2D, a 2d game engine for Lua that also uses SDL2 as a backend.

What software did you use for the 3D reconstruction?

Do you have a source for this? For the most part, rents and real estate prices have been increasing.

Of course, better-known orchestras will first assess an applicant's musical prowess by whiteboard interviews.

If you can't write down Freygish scale, including the dominant fifth, you needn't even dare thinking about playing there.

So they invented 1-day weekends? Time to find investors!

I remember seeing a very different approach with a very similar goal in Vietnam.

In Hanoi, many houses have a small greenhouse-like glass structure on the roof. The greenhouse has a chimney. When the sun is shining, it gets hot in the greenhouse and the hot air escapes through the chimney. A hatch through the roof into the greenhouse draws new air from below, essentially creating a passive, sun-powere air-flow through the whole house, bottom-to-top. Usually some windows on ground level are left open to let air in.

Regarding 5G or barbecued meat?

> certain LTE chipsets have an OFFSET WEEK... and they haven't hit 1023 yet. Oh no. According to what I've managed to dig up, they're going to hit it 2019-11-02 at 23:59:42Z.

Any sources? What is an OFFSET WEEK? Why do you call it "GPS week number rollover" when it is affecting LTE chipsets?
