> a good chunk of the action of my work-in-progress Starter Pack is set on a terraformed Earth-mass moon orbiting a Hycean planet of roughly Neptune's mass orbiting its star in the triple phase zone for water (i.e. where water can exist as ice, liquid, or vapour). The moon in question has spin (presumably it got kicked off by a collision with another proto-moon while the moon system was forming), so a magnetosphere, and tides to keep plate tectonics going--but this time tides from its primary planet, not a large sub-moon of its own.
This makes me so curious as to the approach he's taking with this next book, in terms of the biology of creatures native to these bodies (if they exist). I've been thinking a lot about the approach Andy Weir took for the Eridians: start with the physical characteristics of the planet and reverse-engineer biology that was likely to be viable under those circumstances. As someone who typically writes hard sci-fi, I can't help but be drawn to that approach — too many worlds and environments are designed around the characters and it ends up feeling totally incoherent.
No, she was arrested for disobeying police orders. But whether they're lawful orders or not is a different matter; strongly suspect that if this went to trial, she'd have a decent 1st amendment argument, which is why it won't go to trial. (ACAB, but also this is a pretty standard part of civil disobedience -- getting arrested is just part and parcel, for better and worse.)
You can buy them on your phone in some states, e.g. Georgia. Their "scratch offs" look just like slot machines and give the same lovely dopamine spikes; used to drop $100 in every couple months when I just needed happy brain chemicals.
Even better, honestly: a large bloom filter for the data, such that the likelihood of a collision is relatively low, then send it up to the server for a check. That way there are a small number of erroneous potential hits, but the list never needs to exist on-device.
I just ask our fleet maintenance agent to configure the variants of the new model and then run the bakeoff. In a few hours, I get a doc containing exactly how it performed on my real tasks, against the other models we've benchmarked.
We don't do any "prompt engineering" to make specific models work better or worse, so this gives us a direct comparison that lets us objectively compare how they'll work in practice for different types of tasks.
Good enough to have guided multiple model swaps and measured increases in productivity.
> I certainly do find new slang introduced by gen Z like "he got the riz!" to be quite cringey
This is interesting to me, if only because it's such a natural bit of slang. Given that it's a shortened form of "charisma", this one just Makes Sense to me! I figure it'd be incredibly cringe for me to use at my age, but it's a good term IMO.
This sort of mistake is easy to make when you're mixing up your units; if they kept to one system of measure, it would've been trivial to catch, before or after release.
Some people just prefer to listen. I read well and I read quite quickly -- I don't know how many books I've physically read, but it's gotta be in the high hundreds at least -- but over the past ~10 years I've switched primarily to audiobooks. Rather than being something that I enjoy while I'm doing something else, I typically do something mindless with my hands (weave chainmail, cross stitch, sew) in order to give my full attention to the book.
The astronaut in question may choose to disclose that they had the medical emergency and possibly its nature, but it seems wholly reasonable to not single them out (when it affects the whole mission) or disclose their medical status.
I've been working in security for more than 20 years and have seen the deleterious effects of security through obscurity first-hand. Why does "adversarial engineering" rely on obscurity?
Yeah, I went with that approach for most of the code generation in the emulator I'm currently working on. Source generators handle a few core things, but more advanced compilation tasks went to just ahead of time generation; couldn't get my parser combinator library to play nicely with .NET Standard, so that was just a dead-end.
I love (and heavily use) source generators, but the development experience is godawful. Working with the raw Roslyn types is painful at best and this is compounded by them having to be written against .NET Standard, severely limiting the use of newer .NET functionality.
Eventually I want to write a good baseline library to use for my source generators -- simplifying finding definitions with attributes, mapping types to System.Type, adding some basic pattern matching for structures -- but haven't found a way to do it that's general enough while being very useful.
Boo and Nemerle both were really showing what was possible in .NET back in the early days. I still miss the metaprogramming they had, not to mention their pattern matching (which C# has closed the gap on, but is still way, way short.)
Back in 2005 or 2006, I was working at a little startup with "DVD Jon" Johansen and we'd have Quake 3 tournaments to break up the monotony of reverse-engineering and juggling storage infrastructure. His name was always "xor eax,eax" and I always just had to laugh at the idea of getting zeroed out by someone with that name. (Which happened a lot -- I was good, but he was much better!)
The vast majority of non-text editing in game development isn't done in modeling or image manipulation apps, it's done via the game engine's editor. That's true whether you're using Unity, Unreal, Godot, or a homebrew engine.
There are the rare engines with no editor to speak of -- where things are either done programmatically or other textual definitions -- but they're very very very few and far between.
The engine itself doesn't have a UI, but working with any major engine without using their editor is functionally impossible.
So, it
is possible to use the machine consumable forms of the ISA, but realistically you'll spend way longer fighting it than finding other strategies.
Years ago, I ended up creating my own aarch64 definition, which I use to generate disassemblers, interpreters, and recompilers (dynamic and static) automatically: https://github.com/daeken/SharpRetro/blob/main/Aarch64Genera...
It doesn't have perfect support, but it has served as an incredibly useful resource. I've since generalized it to work for other architectures, and that same repo has definitions for MIPS (specifically the PSX CPU), DMG, and the groundwork for an x86 core. The goal is to be able to define these once, then generate any future targets automatically.
> A qualifying mini app within the Mini Apps Partner Program is one that’s put out by a person or entity that’s not directly or indirectly controlled by you, nor under common control with you.
I don't understand; if it's put out by someone else, how do I participate?
Ventoy is a lifesaver. I dropped a 2TB NVMe drive into a USB-C enclosure and put it on there, along with all the OS installers, distros, and test utilities I commonly use. Probably used it a few dozen times since then and it's well and truly paid for itself!
I've become an unironic proponent of HE, the Human Era. For CE dates, we just add 10000 (I'm writing this from 12025). But for BCE dates, they're subtracted and it makes things so much clearer when it comes to telling how long ago something was. E.g. the sundial was invented around 6000 HE, steel was developed around 9000 HE.
Kurtzgesagt has a really great video about the subject: https://youtu.be/czgOWmtGVGs
There's also a timeline in HE that covers many major historical events: https://docs.wixstatic.com/ugd/71a711_295e365a6ec64d6ca7f87e...
Bolos are used for spin gravity in the first part, but that's very different from the rotovators used in the second part. Both in concept and design. The key point with the rotovator is that the tip is moving at ~0m/s relative to the body it's orbiting when it's at its nadir, allowing you to just hop/grab on.
Back in ~2004, I worked on a project to define a codec virtual machine, with the goal of each file being able to reference the standard it was encoded against, along with a link to a reference decoder built for that VM. My thought was that you could compile that codec for the system you were running on and decode in software, or if a sufficient DSP or FPGA was available, target that.
While it worked, I don't think it ever left my machine. Never moved past software decoding -- I was a broke teen with no access to non-standard hardware. But the idea has stuck with me and feels more relevant than ever, with the proliferation of codecs we're seeing now.
It has the Sufficiently Smart Compiler problem baked in, but I tried to define things to be SIMD-native from the start (which could be split however it needed to be for the hardware) and I suspect it could work. Somehow.
I mean, that seems ugly to me, but... Makes intuitive sense and is fine actually? Is HTML a rich language in which to embed stuff like this? No. Does this clearly get the point across? Yes.
[Edit: this should've actually been attached to the GP comment. I agree with the parent.]
Not quite a cassette anymore, but in 2013 I was in the studio with some friends and we'd do initial downmixes to MP3 and bring them to the car. World of difference, just getting the less-ideal and more realistic listening experience.
Wow. This may be one of the most intense reverse-engineering (and honestly, engineering) efforts I've ever seen for an emulator project before. Capturing the raw LD image to this degree, being able to play it in reverse, etc -- absolutely brilliant. Truly fantastic work.
Oh wow, I need to dig way deeper into this but wonderful resource - thanks!
There's no AArch32 or Thumb support (A32/T32) on M-series chips. AArch64 (technically A64) is the only supported instruction set. Fun fact: this makes it impossible to run Mario Kart 8 via virtualization on Macs without software translation, since it's A32.
How much that does for efficiency I can't say, but I imagine it helps, especially given just how damn easy it is to decode.
(B2-ish Spanish learner here but) "ll" is pronounced in at least three variants that I know of: "y", "j", and something between "sh" and "ch". E.g. "llama" might be pronounced like (in English writing) "yama", "zhama", or "shama". The last one really threw me for a while; it's super common in Argentina at least.
There's a musician named Richie Truxillo who made so many comedy songs about EQ back in the day, but your comment just reminded me of "Has Anybody Seen My Corpse." I haven't thought about corpse runs and dragging folks' corpses back to them in ages!
