Got a new mac with touch id? Use the secure enclave for your ssh keys.
Super weird to see a place I've eaten explode.
Enigma pocket watch.
50 years ago, Douglas Engelbart quietly gave what came to be known as mother of all demos. How has reality stacked up to the vision it implied? Not bad.
I'm working on building a tiny kubernetes cluster at home because I'm insane and I'm excited to try rook.
Would you like to know a lot of things about titanium? Silly question, I know.

Apologies for the impromptu hiatus, back to regularly scheduled weirdness.

First off, I cannot pick a pull quote from this bonkers article: Four Days Trapped at Sea With Cryptos Nouveau Riche.
Using your fingerprint to unlock things is neat but, it turns out, there's not as much entropy there as you might have thought.
I love these little bits of history exposed by geography: Hess' Triangle.
Not everyone is convinced that water cooling is the only way to keep up with the increasing march of TDP: just add more metal.
A plane with no moving parts: ion engines.
I've shared some of Deviant Ollam's videos before but here's This Key Is Your Key, This Key Is My Key.
I guess it's a bit semantics but did you know that energy is not conserved?
Remember when LED flashlights were new and shiny? No? Just me? Well. Now they're boring but there's a new wallet-draining technology: fricking lasers.
Nasal Demons are the best possible case for undefined behavior.
From the unusually-good-looks-at-rockets department: Soyuz going up and Falcon coming down with the spins.

This is a wonderful interview question: You're running IT in a hospital and after replacing an MRI machine, Apple devices newer than the iPhone 6 all start to fail. Older devices are fine and Androids, PCs, etc. are not affected. Try to guess before you read the answer.
In much the same way as LIGO spawned a whole new spectrum of radio astronomy, Spectre birthed an entire family tree of exciting future vulnerabilities
Sorry, we can't build this environment-saving technology. The name is far too twee. I mean come on, "floatovoltaics"?!
Vakyrie's flashback in Thor: Ragnarok is pretty neat. The guy who invented it was a regular IT guy until some dude from New Zealand put him in a film.
Store your cold bitcoins like the pros. Practice writing Smart Contracts(tm) like the pros. Where is the "hard fork like the pros" link? Oh I guess BCH is forking again, yawn.
Wildfires happen fast.
I'm not exactly sure why but a whole lot of LMDB stories cruised across HN at the same time: 1, 2, 3.
Reversible computing, necessary for humans to aestivate, attracts some academic attention.
How come LA gets hidden oil wells? NYC only has vents.
As we all know, the ability of current chromogenic technologies to regulate solar gain with the tunable extinction of phase-change materials is still far from optimum.
More small storage nodes, this time x86 and dual SATA: Odroid H2. No price yet :(
"Stop suing yourself! Stop suing yourself!"
Really enjoying the proliferation of folks trying to find the best merger of strong types and SQL. Now with macros!
RISC-V is either popular or unpopular in China.

Definitely weird: Bees don't fly during solar eclipses.
The most exciting words in science are, of course, 'Well this model doesn't make much sense'. If the tone of that article is a bit too breathless for you, give this excellent HN comment a shot instead. Exciting!
OT vs CRDT: fight!
Apparently, I'm Finnish.
Protobuffers are not universally loved.
It doesn't matter if the cops have your DNA you know, they will find you (source article).
It's been a rough week for state space agencies. Roscosmos had an oopsie which will not help the perception of their previous oopsie. NASA's kind of just hitting itself (but no earth-shattering kaboom so that's something).
Flying car? Flying car!
You can predict which side of the tracks is the 'bad' one: it's the side with all the smog.
Everything old is new again: A statically-compiled dialect of javascript.
Ok, this Bloomberg/Supermicro thing just makes no sense. So far, almost everyone mentioned in the story (Amazon, Apple, Homeland Security, The FBI...) has pretty much denied it, and not in fuzzy carefully-precise language either. Bloomberg though is not so much giving up as doubling down despite their named source not sounding so sure.
Finally, someone's rewriting a real operating system in rust.

I loathe linking twitter threads, they're just reader-hostile. But this one is worth it for the top-quality science.
I guess we gotta talk about the NSA bankrupting Supermicro via Bloomberg (Is that not what it's about?) Vaguely useless HN comments and an in-depth analysis of plausible (but unproven) attack vectors. Also, anyone want to translate this product page?
The only problem with state-sponsored hardware espionage is the lack of a catchy name. Not like iDRACula, which is killer.
"Building an organic computing device with multiple interconnected brains" (2015) leads to a slightly-less-invasive one-bit replication in humans.

Man did I pick the wrong RustConf 2018 talk to pull out the other week. Catherine West gave a great closing keynote about game development and how Rust leads/forces the programmer towards a good design by making some bad designs hard or impossible. A fairly well known game developer was sufficiently unimpressed by this talk to make his own video calling out this conclusion: "The borrow checker isn't beneficial here: you're avoiding it by using a pattern you'd use in C++ anyway.". Oh dear. This led to a veritable cornucopia of blog posts clarifying that you can't 'turn off' the borrow checker, trying to tease out what the disagreement actually was, digging a little deeper into the difference between an integer and a pointer, and of course, Catherine's own blog post digging much deeper into the proposed architecture.
Also in rust-land, Bryan Fucking Cantrill falls in love with rust. (This is pretty much the article I would have written except a thousand times better because Bryan is a genius). See also his videos of the Summer of Rust and the statemaps he talks about.
How many moves does it take to solve a Rubik's cube? 20. Unironically: what a great use of 35 CPU years!
Once you've built your giant orbiting rotating space station, how will you light it up? Geometry.
This is neat: Cloudflare now generically proxies IPFS hashes. That might be the impetus I need to publish this trash to SPACE-COMPATIBLE BITS.

Look how dedicated I am to you all, I still manage to get you your needed Weird through my horrid plague.

How anonymous is zcash anyway? It's complicated.
Timezones are dumb but even by that standard, this is ridiculous.
Guard your metadata. Steps can tell you about videogame releases in addition to the previously-noted secret military bases.
Ok, look. Can we just be a little less on the nose here? Don't introduce the aliens to the AI!
Compilers: apparently just getting started.
You rarely get to see a rocket launch from quite this angle.
You know how I feel about Go. Here are some extra-surprising bits.
Today's lesson, nothing is free. I could do without the breathless prose but hey, payment for order flow is a thing, even for Robin Hood.

I would definitely have reconsidered medicine as a career field if I knew stabbing cadavers with ballpoint pens was a valid research track.
On the other hand, AAAAAAAAAAAAHHH. *gasp* AAAAAAAAAAAAAAAAAAAAAAAA.
"Sudden liquefaction" is a scary phrase but not for the reason you think.
Finishing off this horrible sub-section: straight up Lovecraftian horror, in documentary form: When Snails Attack. Don't worry, humans are still scarier: literal killer robots
If you think you should quit your job, you should quit your job. People stay way longer than seems obvious from the outside.

Some videos on Rust: Bryan Cantrill talks about Joyent statemaps and Tools for thought and several core team members discuss how to build a system of people (don't miss this one).
I feel like someone needs to work backward and write a Connecticut Yankee in King Arthur's Court homage where we intimidate an invading alien force by predicting a supernova.
Thermodynamics kills. I don't mean poetically, I mean the list of academics studying the subject with successful or seriously attempted suicide attempts is ... startling (h/t stefanetal: Ludwig Boltzmann, Paul Ehrenfest, Julius von Mayer, Clara Immerwahr, Gilber Lewis, and Percy Bridgman.

"Many of the design flaws were discovered using formal verification. Academics attempted to prove certain security properties of TLS, but instead found counter-examples that were turned into real vulnerabilities."
I can't remember if I've mentioned the Siege of Leningrad here before but this story of scientists starving to death guarding the food vault is one of the more dramatic true stories, right up there with Petrov and Arkhipov (not to mention Borlaug).
In today's episode, Tesla learns that NDAs expire.
Another day, another new human organ discovery.
Build rust, run {Objective C, python}.
I was reading about the oft-delayed but finally-happening GPS III satellite and now I have Things to tell you:
- It'll have so many signals.
- It's not the only GNSS system up there, of course. Russia has GLONASS, Europe has Galileo, and China has BeiDou. And that's not counting India and Japan's regional systems.
- Signals in this band are a complicated game of finder's keepers.
- The first GPS satellites used Cesium atomic clocks but the new ones might just use Rubidium? Galileo and BieDou use Hydrogen Masers.
- How do you build a hydrogen maser? A weak static magnetic field is applied parallel to the cavity axis by a solenoid to lift the degeneracy of the magnetic Zeeman sublevels, obviously.
Ever wonder why fire drills have a bored, barely-intelligable "fire safety director" reading a script? Because otherwise people burn to death.
Former SpaceX engineers building rockets for bigass planes (shouldn't you have a rocket to launch before you build the giant plane?) and 3d-printed everything. SpaceX is not the only game in town for vertical-landing suicide burns, there's this guy.

Movies love the trope: a boring meeting is interrupted by everyone's phones going off at once and you know Something Has Happened. Turns out, that's exactly what actually happens. (Content warning: gore, terrorism, French). It's also a great look at how preparation and pre-deciding really work when shit gets real.
Another day, another speculative execution attack. Ho hum.

Too much CO₂ in your air? Make rocks with it! It would take 80 billion tons of this to match our carbon emissions but global coal production is ~8 billion tons which is many fewer orders of magnitude away than I would have guessed.
