jaeckel··on 15-minute at-home Lyme disease tick test
Fancy! One can buy a pack of 3 for 30€ in Germany, which detect multiple types of borrelia bacteria ...
jaeckel··on The Serial TTL connector we deserve
Since I once had the case where junk on the line (from a wiggly connection) caused Magic Sysrq requests I'm fully on your side. No junk tolerated for potential hot plug connections.

> you can always try the plastic bag + vacuum cleaner trick - take a thin flexible rope, tie it to a small plastic bag, stuff the small plastic bag into the conduit, use a vacuum cleaner at the other end to suck the plastic bag & rope through.

That's absolutely great! Worked like a charm two days ago and everybody cheered and laughed who saw it :-D

Does someone have a recommendation for a specific material the string should be made of?

ImgurViewer from fdroid on an FP5 opened it blurry after around 5s and 5s later it was rendered completely.

Pan&zoom works instantly with a blurry preview and then takes another 5-10s to render completely.

I'd be very much interested in those documents.

jaeckel··on Bambu Connect's Authentication X.509 Certificate and Private Key Extracted
I'm a bit surprised that nobody mentioned prusa as a replacement?

FMU that's where Bambu originally copied from!?

My short dive into 3d printers stopped once I was highlighted to the micro plastics pollution they create in the air, but still I would've gone for a prusa, already because all parts are free soft- and hardware.

Or is there anything else I'm missing?

It's an evolution of said papers and AFAIU improves the attack to a level that makes it executable.

Cool That looks nice! Thanks for the pointer

Surprising indeed, that none of the two boards has Ethernet

jaeckel··on Getting Started with FPGAs
Did anyone try out the CologneChip GateMate FPGA? It's supposed to have a completely open toolchain, but the dev board isn't exactly cheap at 230€

That's why you do thermo solar in hot regions.

jaeckel··on Ask HN: Marketplaces for Embedded/FPGA Developers
If you give a short description of what you need and contact details, your search is maybe already over, as on this site are also some freelancers with FPGA&|Embedded experience.
jaeckel··on Digital signatures and how to avoid them
The answer is: dedicated CPU instructions for SHA256 vs. software implementation of SHA512. For amd64 there's SHA-NI, for Arm there's the crypto extensions, but both only provide sha256 (at least when I last looked at their specs)

Absolutely this. Less microplastic FTW.

For lasagna we cook the ragu etc for multiple times eating, then we prepare the glass boxes as if they went to the oven, but put them to the freezer. Finishing this is basically: put the box from the freezer to the oven, then turn on the oven and bake for ~75minutes instead of the usual 60.

IKEA and DM (in Germany) have also nice glass boxes which are not as expensive as the Pyrex ones, but especially the cover of the Pyrex are better IMO.

> Sure, if you have money you can go with a reputable brand like Bosch & Siemens

Just FTR they're exactly the same -- "BSH Hausgeräte GmbH" -- with just a different label on it. ... And I didn't have a single good experience in the last years, IMO they're designed for planned obsolescence.

E.g. my premium Bosch Hand mixer broke after 2.5 years. Afterwards I bought a >35 years old used RG28e for half the price and it's still going stronger than the Bosch ever was, 5 years later.

> if you have even more money you can go with Miele

If you buy cheap (or uninformed) you most likely buy at least twice.

Very common model in Germany as well, called Erbbaurecht. The land is usually owned by the Catholic Church or the city itself. They then give you a lease valid for 99 years and after that time the land falls back to them.

Would've been cool for safety applications if the second core could be run in lockstep mode.
jaeckel··on Optimizing a bignum library for fun
If you're interested in even more details you could also have a look at Tom's book about bignum arithmetics. C.f. third paragraph of https://github.com/libtom/libtommath#summary

The library evolved since then, so the algorithm documentation only exists in code nowadays.

FTR I'm involved in the project as maintainer.

Would you maybe share with us how you built it/which parts you used?

If we ignore the fact that switching between those two formatters would "break" the formatting: There exist clean&smudge filters in Git, which could accomplish this technically.

jaeckel··on Fairphone 5: Keeping it 10/10?
Sorry to hear that! I have a pretty low sample size of ~8 friends on FP3 and I can't remember hearing of a single hardware failure. Some batteries got replaced and some are even still going strong on their first battery. I've updated mine from 3 to 3+ and I'm on my second battery since this summer, I.e. the main board is ~4years old. A friend had some minor issues in the beginning with some internal connector but I can't remember him mentioning it again.

Another friend got rid of her FP2 this spring in favor of a FP4, but only because some apps she uses got really unusable. Otherwise she would've stayed.

IMO it's a fairly good platform and I'm looking forward to how it evolves in the future. Hopefully they will introduce a smaller phone at one point.
