Check out Precursor (FPGA device with softcore CPU running on it for trustability).

Xous (microkernel OS for Precursor) has an application called Vault that does FIDO2/U2F as well as password management and USB HID emulation.

Much more on the dev board side and probably overkill for just this purpose but a really cool device.

Doesn't Ardour support VST?

Heads up your link is broken, doesn't match any PRs on that repo.

That channel is great, would be great to find repositories of similar hacker/electronics channels, if anyone has some.

Anyone tracking signup conversion will realize that phone numbers are autofilled whereas 2FA requires an installation for a greater number of users, leading to drop-off.

Most enduring sofware is always those "one-off prototypes" that people cook up over a few days.

I'd buy this (and gift it to everyone I'd think would like it) in an instant. Especially if you somehow included and refined the analysis you have in the blog posts.

You run into ToCToU issues. Even if a chip is "open", how can you be sure the chip you have corresponds to the specification? If that isn't a concern, any FPGA based SoC fits the bill, for example the MNT Reform Kintex-7 module (https://shop.mntre.com/products/mnt-rkx7-fpga-module).

Supply chain attacks can be mitigated with "golden chip analysis", you destructively analyse a known good chip after measuring various power and timing benchmarks across adversarial configurations, and repeat those measurements across all future chips and check they are within margin of error.

Different product at a different price point with different objectives. Security keys are suitable for mass deployment across an entire workforce, precursor aims to be a launchboard for general purpose secure and trustable computation. Even at mass production prices, precursor would likely still cost more than 100$.

Good at what they're being programmed for is a bit of tautology.

FPGAs being selected for performance per watt was only a fairly recent phenomenon, when they were deployed on semi large scale as password crackers/cryptocurrency miners.

Their real strength is ultimately real time processing (DSP or networking), with reconfigurability often quite valuable for networking applications. For DSP applications it's usually because a MOQ of custom silicon can't be justified.

Huh?

I quickly scrolled through and he does mention a move which could explain the tree change.

This is a pretty generic homelab, there's communities built around the hobby on reddit or lemmy.

It's 10k+ of equipement at retail but people in IT often get inside deals on old equipment that's being upgraded.

Some software has PDF reflow, like koreader.

Those boxes are at higher price point, but far exceed the apu lineup in features/compute.

Remember to contribute money/time if you love and use emacs!

Microsoft recently cancelled PayPal for Github sponsors and Tarsius lost significant amounts of income (that was already below minimum wage)[1].

A small contribution, the price of a coffee a week, which for successful developers is very little, goes a long way in supporting open source that doesn't have extensive corporate support like chromium/linux/docker.

Geocoding is a non-trivial problem, and OSM's engine,Nominatim [1] isn't great.

What exception? If you are a citizen and intend on returning to the US (or even intend to renounce) you should be in good standing with the IRS (FBARs and annual filings). You owe the difference between locally paid taxes and federal taxes, and can claim overpayment as tax credits.

Most low-earners don't bother with this and use the Foreign Earned Income Exclusion Act [1]. Don't forget about FBARs if you have more than 10k across foreign banks accounts.

Some folks over at r/ergomechkeyboards have done this (for example https://redd.it/yhioec). Also probably worth checking out https://www.reddit.com/r/trackpoint_builders

Gwern's fairly comprehensive blog post [0] could be a good starting point.

It's available as grey-market generics shipped from India (in the US). That said, it is Schedule IV.

It's fairly well tolerated and widely prescribed for narcolepsy, and used off label as a 'nootropic', or cognitive enhancer.

Ironically enough, the rate of adverse effects might actually be comparable to Advil, and modafinil has a noticeably lower median lethal dose.

Would you say Kagi has escaped the Google SEO deterioration? Google has essentially gotten so bad for me that DuckDuckGo, without noticeable improvement, is now on par with Google.

Yeah, I'm kind of flabbergasted to be honest, total failures like that are rare for metal tubing.

You can find bespoke assembly services with a lot of the vendors, it will usually run around 100$ extra so 300/400 for the keyboard which altogether isn't that bad compared to prebuilt ergos like the Ergodox.

These tend to be location specific but try to find regional resellers of the PCBs.

Also worth checking out r/mechmarket, i.e. https://redd.it/wvf9dz

An interesting approach to vendor-independent attestation was outlined in [1]. Basically the bitstream is fed into a physical unclonable function (PUF) which is used to derive a key to decrypt the rest of the bitstream. For attestation, one could simply store the secret part of an asymmetric key in the encrypted bitstream (for challenge-response).

There's a tradeoff between decentralization and throughput. In the extreme, only people owning entire datacenters could operate a full 'node' that would be processing 1 000 000 TPS.

Slowness is not the mechanism, ETH had ~13 second block times before the merge. Bitcoin is slow because the difficulty is targeting longer block times, not because of inherent need for slowness. Difficulty is only required so that adverserial agents (with less than 51% of hashpower) can't rewrite the chain and change transactions.

Scarce energy does not secure PoW, the value of the mined currency does, in the same way that scarce supply does not secure the gold standard, it's the value of gold (the 'fiat' shared illusion that it's a reserve).

I can fork a PoW chain with a difficulty bomb so that the difficulty is 1000x that of mainnet for any given hashrate. Energy is still scarce, you can't double spend energy on my chain and the 'real' one. Yet my chain isn't secure, because no one will recognize it as canonical: the rewards it yields aren't worth expending effort for.

I think you're confused about what the chain is securing. It's not who owns what, it's who spends WHEN. Distributed consensus of ownership does not require PoW/PoS, these were invented to solve double spending/censorship attacks that were a problem in P2P networks.

You can't attack a chain to muddle the past, only the present. A successful attack on ETH won't change who holds ETH, it will only prevent agreeing on who receives it.

Hard question to answer without specifying topics. The usual way is to find an introductory textbook on the subject, find the papers and authors referenced for results and theorems and work forward through the literature. This will give you both historical perspective and develop your knowledge at a gradual pace.

Kind of reminds me of https://en.m.wikipedia.org/wiki/The_Thing_(listening_device).

What are the alternatives with these specs (power draw, mainly)?
