Right? If you spend time around drummers at all, you almost definitely know the name Zildjian (the same way drummers know the names Fender and Gibson).

Please don't do this. You're not going to hit a drone at any appreciable altitude from a "high window" with a "nice rifle." One of the first rules of putting bullets downrange is to know what's behind your target, and you simply can't know that when you're shooting into the air.

This depends on `liar.hats` being undefined, but what if `liar.hats` is an empty array? That seems like an equally valid way of representing a person that owns no hats.

From the page header, it sounds like the author is Roderick Beck:

“Roderick Beck worked as a sales contractor for Hibernia Atlantic and helps buyers procure capacity and providers make sales.”

I thought this was going to be a strange read about the Hayes command set[1] at first glance.

I'm assuming the parent is making a 1.21 Gigawatts joke, a reference to Back to the Future.

Yeah, I came here to say the same thing. Why not just memoize compile()?

I realize single-action is generally very safe, but this is the exact reason I fell in love with the P99 AS action (striker-fired SA/DA with a decocker).

I remember this being the way to unlock Athlon XP’s (though if you bought the mobile version, which used the same socket and ran just fine in a desktop motherboard, they came unlocked from the factory).

I realize this is a joke, but can’t resist mentioning that LimeWire was (is?) open source (or at least used an open network in GnuTella)

Yes and no. They also dragged their feet on high-throughput Ka-band spacecraft with smaller spot beams. ViaSat built and launched ViaSat-1 while SES was still ordering satellites designed around analog video broadcast.

In the terrestrial real-estate analogy, this seems to me like missing out on potential returns because you built the wrong type of building on the land you own.

In a lot of ways, I think this is an accurate take. I worked at SES for years, starting at NewSkies Networks (I was there through the SES acquisition when they merged us with Americom), then a second stint at O3b (just before SES fully bought the controlling stake). My take may be a little short-sighted, as I was really young at the time.

The thing that struck me is that they operated more like real-estate investors than tech companies. Geostationary satellite technology had remained largely unchanged for a couple decades, so these companies were engaged in the business of:

- Obtaining real estate (an orbital slot) - Putting a big, expensive, largely commoditized[1] asset on that real estate - Operating that asset as efficiently as possible to achieve a good ROI

This meant that the executives were often stronger at things like financing hundred-million dollar purchasing projects (a huge skill on its own) and running a skeleton technical operations staff (to keep OpEx down), but lacked the foresight to see what the Internet meant for their product relevance.

1: Of course something as technically complex as a spacecraft isn't a commodity, but there was largely no differentiator in what it _did_: receiving, shifting, and re-transmitting analog RF signals, almost always in 36 MHz and 72 MHz wide chunks. You could buy one from Thales, Lockheed, Boeing, etc., but to the operator's customers, they all basically looked the same.

I mostly agree, but here in NYC I don’t have a car to keep the bags in. If I stop at the grocery store on my way home from work, I either have to have planned ahead and put a reusable bag in my work backpack, or I have to buy more reusable bags (which eventually get tossed because we have too many of them).

It’s definitely better to have the bag with me, and just typing this out made me realize I can keep one or two in my backpack at all times.

In the context - a hackathon sponsored by the US Department of Defense - it has great utility. GPS (and any radio-based location system) is quite vulnerable to denial by enemy jamming. This technique would by extremely relevant in a war between peers, and probably provides a much lower cost option than high-precision inertial navigation systems.

Tangentially, this isn't really new - ground-pointed RADAR system combined with a good terrain dataset can also be used.

For the electrical components, Digi-Key[1] and Mouser are the two go-to’s. I didn’t read 100% of everything, but unless he’s selling the PCB’s you’ll have to get them fabricated from the Gerber files in the repo. JLC is the go-to for this - expect to pay $5-$10 for a single-sided design like this, and you’ll probably get free shipping if it’s your first order.

I have much less experience with QLab, but I just used it for the first time in a real project, and was extremely happy with the whole experience. We’re playing back soundscape cues sync’ed with a kinetic sculpture, all triggered with OSC from the main server controlling the sculpture.

QLab was the least painful part of getting sound and lighting integrated. If the lighting system we used (Madrix) was half as easy to work with as QLab, I’d get dozens of hours of my life back.

This. When I was still doing infra for a large recommendation engine, the training was what got the big GPUs. Inference was on CPU or (later) ASICs (may have been FPGAs?).

These are used in disaster response and other scenarios that demand rapid deployment of satellite terminals.

I chuckled at this, because 6 GHz was until recently widely used by the satellite industry (C-band) for ground to spacecraft uplinks. They've had to vacate it as the spectrum has been re-allocated for terrestrial use (LTE-A, WiFi 6E, etc.). This is a great thing, too - 4-6 GHz is pretty much ideal for terrestrial use. C-band was wasted in space.

Ka-band (18-30 GHz) used to be the new frontier for satcom - it was what everyone was excited about the last time I worked in the industry (2014). The advances in mm-wave devices over the last decade are mind boggling.

It’s by far one of my favorite machines, even though I’ve never used one (and am far from a print designer). I just really love that it’s basically the traditional screen printing process, but automated.

Sounds like you’re looking for T-digests[1] - most production systems I’ve worked on that do this are using them under the hood.

I grew up (as a white American kid in Virginia) often adding a slice of American cheese to instant ramen, and I can confirm that it’s delicious.

That’s fine, as long as you have obtained permission from the copyright holder to create a derivative work. Otherwise, their reasons very much do trump your reasons.

I also really like the theatrical world’s convention of “upstage” (further from the audience) and “downstage” (closer to the audience) - disambiguating the front and back of a stage.

I can only assume you’re being downvoted because folks are thinking that you can’t go supersonic without making a boom. While this may be true, it doesn’t change the fact that you make a good point - regulation should be made as close to externalities as possible. If it makes the upstream thing impossible, then fine, but let’s actually regulate what we want to regulate.

I may be missing something, but it’s quite similar to pkgconfig+(cmake|autoconf). If you include a header, your build system probably needs to know where on the filesystem that header exists.

Perhaps you’re thinking of the considerably faster 28800 modems?

Thanks! This prompted me to look up the flag to enable this. For GCC it’s:

  -Werror=format-security

TLM (at Facebook) stands for Tech-Lead Manager - it’s a hybrid role, with engineering duties and people management duties.

From what I remember, it wasn’t intended as a long-term position, but was used in stop-gap circumstances (manager quits, tech lead temporarily takes on some people management duties) or for when an engineer was considering transitioning to the management track.

I learned to program in my early teen years from books I checked out from the library, but since then didn't read a single programming book.

Recently, I needed to ramp up quickly on an embedded C project (without any past MCU programming experience), and turned to a book for the first time in ~15 years. It was a refreshing experience - it was a short book, and I read it cover to cover over a weekend, but it really enabled me to be successful in the project I had to take on.

I like to think of real-world experience as building a sponge: you fill in the areas that you need to as you go, creating a sparse structure of knowledge. This complements formal training (whether a book or a class) - I think of these more "complete" approaches as pouring water into the sponge. Having hands-on experience lets you take more advantage of a class or book, and the class or book fills in the gaps that you simply didn't have to learn as you built things.
