I attempted Advent of Code in 25 different languages last year. Learn X in Y was extremely helpful for picking up basic syntax etc. when trying to speed learn enough of a new language to get by each day.

(Made it to day 16 before Christmas Crunch kicked in, but it was a great challenge)

I love the idea of Cloudflare workers & really want to play with them in some spare time, but I've not really got any idea what I could actually _do_ with them ...

What are people using CF Workers for? Any interesting use cases?

Yes, I believe all 737 MAX have MCAS.

It's the Edgley EA-7 Optica

DDR5 include on-die ECC. Which is very different from traditional ECC. But many vendors marketing (and many enthusiasts are talking) as if it's the same. See [0], there's some really good explanations in the replies.

This might be completely irrational, but it really annoys me when the press use 'big.little' for all heterogeneous CPUs. big.LITTLE is an ARM trademark for ARM's implementation of heterogenous designs. Intel have clearly decided heterogeneous is a marketing no-go and have gone with 'hybrid' architecture, which is fair enough. But these are absolutely not big.LITTLE CPUs.

Really shows you what an excellent job the Apple Silicon team have been doing. Latest A series SoCs are ahead of the Android competition by miles in most metrics. I was hoping custom Google Silicon might get closer to competing, but maybe I had my expectations set far too high.

> Will app developers get access to the Tensor chip?

I think this is another classic bit of Google branding. Tensor is their custom SoC with CPU, GPU and an ML co-processor (think this was codenamed Whitechapel). Not the ML processor itself. Whereas Google's Tensor Processing Unit is a large scale ML accelerator. Why they've decided to use the same name for two totally different chips with different functions is anyone's guess.

The Swiss cheese model of accidents. Occasionally the holes all align.

Best visualisation of the Photoshopping of some of the images used in the article:

They appear to have taken images that had previously been published and for whatever reason, modified the sand around the remains.

Can this record the output of other audio/music creation apps (thinking like synths, instruments or AUM) or is it just the microphone?

Significantly quieter than car traffic noise. Struggling to see the issue here.

Does Podman offer anything similar to Docker Swarm? I absolutely love Swarm mode (yet to find a simpler way of organising containers over a few small nodes), but do not want to deal with Docker the company.

> not for Desktop PC's

Intel don't agree. They are using a heterogeneous architecture for desktop class chips in upcoming Alder Lake processors [0]

Do you have a source for that quite extraordinary claim?

Vostok 1 is a tricky exception because there was no gurantee Gagarin would be conscious or even alive when he got to space. That mission had to be automated.

But he had a role other than just being a passenger. He was there to make observations on the performance of the rocket and the spacecraft, as well as himself throughout the mission. There's a clear scientific role here that the Blue Origin tourists do not have. And while the controls were locked, Gagarin had the code to unlock them and was to take over the spacecraft in the event of automation failure or another manually recoverable emergency.

Most manufacturers haven't used Diacetyl in their juice for years (like 7+ years by now).

Soviet Mars 3 was also the first probe to achieve soft landing on Mars. Like most of the Soviet Mars missions, it failed, but it failed only after landing (unlike most of the rest ...).

If you're thinking "how bad can it really be?", please treat yourself to watching a couple minutes of "gameplay".

It's incredible to me that this project got any VC backing. 2 man team with barely any background in game-dev are going to build an exceptionally ambitious MMO? The red flags ignored are just absurd.

What is a DDP? I tried searching but couldn't find anything that seemed relevant

This is already common in the satellite world. Companies design & build satellite platforms (usually called "buses" for sats) that satellite developers build on top of. Usually provides the core physical structure, plus attachments for payloads or sensors; some more advanced ones also include stuff like avionics, power distribution etc. Wikipedia has some interesting examples [0].

Photon mentioned in a sibling comment builds on that idea by providing a bus with engines to make it into a simple spacecraft. I don't know of any off-the-shelf rover platforms yet but can absolutely see the same thing happening when there's enough demand / cost of access to places worth roving around is cheaper.

Nice work on the sim, that's really cool! Love the synced video as well.

This is such a fun space to fiddle around in as an amateur. I've been experimenting with using actor systems for automating Kerbal Space Program with the KRPC extension; first projject can get a Vostok-like ship into orbit [0]. I thought I knew quite a bit about rocket guidance & control until I started writing these wee projects! And that's even using the simple "auto-pilot" built into KRPC to keep the rocket pointing in roughly the direction I tell it. I've been very slowly starting out on a new system which uses parallel WASM runtimes, so you can program rocket control in any WASM-targetting language. Starship/Falcon style landings are definitely one of my goals.

The ability for planes to follow these highly accurate common flight paths was a contributing factor in the Gol flight 1907 mid-air collision in Brazil [0]. (That, plus ATC clearing the two planes at the same altitude _and_ both having TCAS (Traffic Collision Avoidance System) switched off). William Langewiesche published a great long-form article about the disaster called "The Devil at 37,0000ft" that's well worth reading if that's your sort of thing [1].

There's a lot of effort going into researching ways to make booms from SSTs quieter. NASA's has a low-boom research program trying to turn the booms into "gentle thumps" by changing the shape of plane's shockwaves [0]. Lockheed are building the X-59 for demonstration flights for the program.

Anyone seeing this that has any interest aviation disasters, AdmiralCloudberg (author of article linked in parent) produces some of the best disaster write-ups I've found online. They post an article every Saturday, each covering a different disaster. Doesn't shy away at all from the technical details but they're easily digestible even to laymen with little-to-no background knowledge of aviation. There's a back catalogue of ~100 articles so far, guarantee you'll learn something from each one.

They're the cheapest EC2 instance type, so they're very attractive to small scale deployments like side projects, personal sites etc. (basically anything that can run on one or two small nodes) where budget is a major concern. The t4g.micro is in the free tier as well, so that'll help.

I host a few very low traffic sites & I'm in the process of switching from a basic DO Droplet to a pair of low-end Gravitons. Will save me money and give better peak performance for my workloads.

Scotland is aiming to be a world leader in tidal energy [0]. Which I guess makes sense given we're practically surrounded by pretty rough seas. Shetland has just had a tidal energy electric car charger installed [1]. Bit of a gimmick but the Scottish government is serious about making this a significant source of energy.

As other have said, it's a tech demo. Partly just to show we can do powered flight on other celestial bodies, part of it is to test how well the off-the-shelf parts in Ingenuity work in that environment. Rotorcraft require more computing power than is available from typical rad-hardened processors. Ingenuity is using a Snapdragon mobile phone chip, will be interesting to see how long it survives up there.

NASA have plans to use rotorcraft in many future missions, including the Dragonfly which will fly around Titan[0]. Launches in 2027.

Even before 1991 many of these theories could be disproved.

James Oberg was uncovering info about phantom or missing cosmonauts in the early 70s, including photos of the original class of Cosmonauts before & after some were airbrushed out. At least 5 men were removed from the photos and they have all been traced (Grigoriy Nelyubov being the most high profile as a member of the "Sochi Six") despite Soviet space officials going to significant lengths to excise these men from their history.

Since the Fall of the Soviet Union we've had revelation after revelation about embarrassing episodes in Soviet history (including previously covered up issues with Vostok 1 during its flight), yet we've discovered nothing about further missing cosmonauts. Of course there could be much better covered up episodes, I'd just expect we'd know a hell of a lot more about them by now.

(As an aside, this info is from Oberg's 1988 book "Uncovering Soviet Disasters" which has _fascinating_ little passages about how much more open the Soviet Union has been "recently" with regards to publicising disasters under Glasnost and how that will continue into the future. So interesting to see as someone born shortly after the fall of the Soviet Union.)
