tashbarg··on Btrfs Notes
The article is mostly concerned with the author not understanding BTRFS and ranting about it. To a degree, that one must assume, the author intentionally gave up early on understanding and simply rants about everything that does not look or work as usual.

Would not read again.

tashbarg··on Show HN: Paperd.ink – an open-source e-paper development board
Probably because diagonal is the only supplied value. That is mostly used for comparing screen sizes and little else. At least in my metric world.

You could probably measure screen sizes in fractions of blue whales and it would work out exactly the same for most folks.

So, in the described scenario, the password never shows up in the keyloggers log. Works as intended.
tashbarg··on Ask HN: Internet magically gets faster when opening speedtest?
Some providers provide speedtests that test (only) last-mile speed between, e.g., cable modem and head unit. Mine does that and reports 1Gb/s just fine. Of course, only to the head unit, nowhere else in the universe.

> 7B people now, another 20B in our children's lifetime.

The UN projects ~11B total by 2100 [1]. Most of the growth currently is and will be because of people surviving birth and living long. Global fertility rate is already down to 2.4 (from almost 5 in the 50s) and very likely will keep going down. That's why projections even see a decline of total population after 2100 as likely.

> this m.2 to SATA port replicator reportedly works perfectly with Linux

That's a port multiplier and if that works or not depends more on the SATA controller and less on the operating system. Far from all SATA controllers support port multipliers. And even less support fast port multipliers (FIS), which is not much of an issue if your main target is size.

tashbarg··on Write plain text files
Git stores a new file anyways. It’s only for packs, that delta compression is applied. And delta compression handles binary files.
tashbarg··on Apple's custom NVMes are amazingly fast – if you don't care about data integrity
That's not the right keys and not the right order to do that. You should not flush caches before you terminated as much processes as possible correctly. And you are rebooting at the end.

REISUB for a somewhat safe EMERGENCY reboot and O instead of B at the end for shutdown.

tashbarg··on SHA-1 'fully and practically broken' by new collision (2020)
My fossil knowledge might be a fossil itself, but isn’t the database used for everything?

If someone gets hold of the hashes, they already have everything. So, whats the threat that is enabled by poor pw hashing?

Anyways, passwords should always be hashed with good password hashing functions (not all kdf are good for that) even if it is not strictly necessary. Just in case.

tashbarg··on SUVs are offsetting EV car gains
Here's mythbusters doing it: https://www.youtube.com/watch?v=lttgT1XZVvE

They estimate the savings at insane 20 feet at 20 something. Far from your claimed 100%.

Could it be, that your road is not as flat as you think? That would also explain the necessary braking to not run into the truck, wouldn't it?

But I couldn't agree more: let the machines do that perfectly and safe. Let's reap those sweet 25-50% increase in fuel efficiency.

tashbarg··on SUVs are offsetting EV car gains
This [1] claims 21,725km for the US and only 13,518km for Norways energy mix. The 100,000km number is quite old and was corrected down and down again several times due to more efficient battery production and changing energy mix.

While we are a lot of humans, we are nowadays far away from having too much kids.

Worldwide, we are already close to the replacement rate and projections see us falling below by 2070.

Most of the population growth is actually not "new kids getting born", it's "folks getting older than the generations before".

So, if population growth is your concern, don't tell people to have less kids. Tell them to stop getting so old.

I seriously doubt those numbers (-50% fuel, energy harvesting by driving behind a truck) AND you are giving incentive to try dangerous driving.

Please either back those numbers up with evidence or remove them for the sake of road safety.

tashbarg··on Examining Btrfs
There’s no need for changing mount options. If you want to allow mounting of degraded arrays, just put the degraded option there from the start.
tashbarg··on Examining Btrfs
In BTRFS, RAID1 simply means 2 copies on different devices. There is RAID1C3 and RAID1C4 if you want more redundancy/copies.

This whole critique boils down to poorly chosen naming and bad documentation. Both VERY valid critique. But feature-wise, BTRFS delivers „classic“ RAID1 and more/better. It’s just hard to find and easy to misread.

Minimal Image Viewer has been built in Electron…

So, only minimal in terms of features, I guess.

tashbarg··on Unsong, a fantasy novel where the universe is programmable with Hebrew (2015)
Disclaimer: it's been a few decades since I read that. I may be completely wrong.

It's not like you can simply say something universe-altering just because you know the right words. You still need the magical ability and if you're not powerful enough in that ability for what you want to say, you simply can't say it.

But otherwise, if the mage is THAT powerful, then, yes, the rest of the universe has to deal with it.

Ursula K. LeGuin, Earthsea.

From Wikipedia: One vital aspect of magic is that it is impossible to lie in the old language, so that magic works by forcing the universe to conform to the words spoken by the magician.

tashbarg··on ArchiveBox: Open-source self-hosted web archiving
Isn't this just passing the URL to archive.org which then does the actual archiving?

If it isn't already public (i.e., reachable by archive.org), it won't be afterwards?

> You can see that we transmit in this example at two different frequencies, 19kHz and 18kHz.

Not „just out of hearing range“ for some people. Especially young people can hear up to 20kHz.

This desperately needs a disclaimer: unless you are only experimenting/learning, keep away from this code. If you're looking for something that you can use in a real project, use SimpleBox from the rbnacl gem.
