FredFS456··on Alphafold
There's a preview paper as well: https://www.nature.com/articles/s41586-021-03819-2
FredFS456··on Valve Steam Deck
Does this mean it's a next gen AMD APU, since it uses LPDDR5? I don't think Cezanne (current Zen 3-based APUs) support DDR5.
FredFS456··on Podswap: Keep airpods alive and out of the landfill
Neither 0% nor 100% are dangerous, but lithium ion batteries wear out a lot faster if you cycle them all the way instead of only staying within 20-80%.
FredFS456··on China lands rover on Mars
NASA has been soliciting lander designs[1], as well as coming up with their own[2].

FredFS456··on PocketPCR
PCR (Polymerase Chain Reaction) is the standard procedure for duplicating DNA, which is a critical step to many different protocols, including COVID tests (real-time PCR) and DNA sequencing. This device is a miniaturized thermo cycler, which heats up and cools down a sample in a small test tube according to a pre-programmed sequence. Heating/cooling cycles are necessary for the enzymes involved in PCR to do their jobs.
FredFS456··on Google have declared Droidscript is malware
There's nothing wrong with the appliance business model - embedded devices that use microcontrollers are Turing complete and yet no one complains about those. It's only when devices are marketed as general-purpose (i.e. smartphones, PCs) but are locked down to prevent running arbitrary user-loaded code that it becomes a problem.

FredFS456··on China accused of forcing 570k people to pick cotton in Xinjiang
I have some anti-china bias (personal background), but many times these Xinjiang articles only cite Zenz et al. I would really appreciate better investigative journalism on this front.
FredFS456··on Downsampling Time Series for Visual Representation [pdf] (2013)
Why not just use a low-pass linear-phase FIR filter instead of FFT/iFFT? Same result but achieved in time-domain, somewhat more performant.
FredFS456··on Nextcloud Hub 21
In my experience of running my own Nextcloud instance for over 4 years, I've never had an upgrade break my instance. Caveat: I'm on the stable channel and I only update when the client prompts me to update, which is a few point releases into a new release.
FredFS456··on ‘It just blew fire’: Kauai woman watched as an engine fell apart on flight 328
Regulations require that two-engine planes (twinjets) be able to fly level with one engine out.
FredFS456··on ‘It just blew fire’: Kauai woman watched as an engine fell apart on flight 328
I'm going to educate you more right now - jet fuel is not explosive in the sense that you think it is. It's much less volatile than gasoline and is regularly dumped overboard in emergency situations with no fire risk. Modern jets can fly just fine with one engine shut off like in the OP. Provided that there is enough altitude, planes will glide their way to back a runway to land if both engines go out. The structure can take way more abuse than you think - see this picture of a 787 undergoing a wing structural test. http://blog.flightstory.net/wp-content/uploads/787-ultimate-...
FredFS456··on Uighurs: 'Credible case' China carrying out genocide
I don't believe there is sufficient evidence for mass casualties, but the OP is arguing a different tack: they're saying that we have evidence for forced sterilization and targeted oppression of the Uyghur culture, which by their sources can be construed as genocide.

FWIW, usrfiles.com seems to be a CDN associated with wix.com. glanlaw.org has DNS registered with wix, so I expect they're hosting there too.
FredFS456··on Perseverance Rover lands on Mars [video]
It will be a while before they get better images downlinked. The radio link is unbelievably slow by modern internet standards[0]. Note that the faster 2 Mbps link is only available when one of the orbiters is overhead (4-6 times/martian day[1]). They also have a lot of work to do checking out the rover systems making sure everything is healthy, etc.

FredFS456··on Perseverance Rover lands on Mars [video]
Perseverance's Terrain Relative Navigation uses a camera system and generates a full 3D position fix, but the idea is similar.

They can't redistribute existing componentry because of competing requirements: during cruise, the spacecraft needs to be balanced around the rotational axis (perseverance rotates at 2RPM in cruise). During re-entry, an asymmetric weight distribution is needed to generate lift.
FredFS456··on Google Stadia shuts down internal studios, changing business focus
GeForce Now can be used with Steam quite seamlessly. In fact, GeForce Now's value is to play the games you already own on various platforms on their hardware. They're not trying to be another games store.
FredFS456··on The CPUs of Spacecraft Computers in Space
Low Earth Orbit (LEO) which the ISS is in is very different from deep space. You can get away with much less radiation hardening in LEO. For example, I know a company consumer-grade Xilinx MPSoCs with 4xA53 cores at 1.5GHz.
FredFS456··on Apple M1 vs. Ryzen 3900X vs. Intel I9 in Software Development
I would assume that they would go under the Fire branding, like FireBook.
FredFS456··on Apple M1 vs. Ryzen 3900X vs. Intel I9 in Software Development
Sure, for the instruction set all the CPUs are required to be compatible. However, Apple seems to be going in the direction of having many many hardware accelerators builtin to their SoC and integrated into their software ecosystem. I assume that if Google and Amazon were to build their own chips, they'd do the same. Those accelerators will not be intercompatible, and we'll have a dozen different vendored drivers, like how GPUs work.
FredFS456··on AlphaFold: a solution to a 50-year-old grand challenge in biology
There are post-translational modifications to proteins. This means that for many (most?) proteins, the amino acid chain sequence is different from what you would predict from the DNA. These modifications are dependent on the state of the cell at the time of translation, and so cannot be predicted from the DNA alone. Even with a 100% accurate folding model, we cannot simply know the shapes of all the proteins inside the human body based on the genome.
FredFS456··on MODNet: Is a Green Screen Necessary for Real-Time Human Matting?
I'm sure it's great, but we'll have to wait for the source/demo/pretrained model to really tell.
FredFS456··on AMD at a Tipping Point with Instinct MI100 GPU Accelerators
ROCm (https://rocmdocs.amd.com/en/latest/) is their compute framework/stack. Not as good as CUDA but has support for Tensorflow etc
FredFS456··on The Earth Is Pulsating Every 26 Seconds, and Seismologists Don't Agree Why
I had a subscription to Discover a number of years ago. I'm sad to see that they've started dumbing things down.
FredFS456··on Wikimedia is moving to Gitlab
Already exists: https://github.com/dessant/buster

Edit: on re-read, you meant solving using humans. Buster uses speech-to-text APIs to solve.

FredFS456··on AMD Reveals the Radeon RX 6000 Series, Coming November 18th
https://github.com/RadeonOpenCompute/ROCm#Hardware-and-Softw... Note that ROCm does not have support for even the current-generation of gaming GPUs (Navi).
FredFS456··on Voyager 2’s Discoveries from Interstellar Space

FredFS456··on Wireguard-docs: Setup, usage, configuration, and a full example
The Rust implementation is very incomplete, I believe you'll have better luck with the Go userspace implementation.
