As always, there are some very erudite comments here on HN, which is why I like the site so much. My erudite comment, or rather question, is this: why aren't these people using AI to solve all these problems? Surely it would be a good test of The Product and maybe it would give s[ck]eptics some food for thought?

Why not ask someone that can do astrology to do your stock picks and sports bets for you?

You know and I know that The Product is at best nowt more than 'astrology'. The Product does do search engine things though, and it could be scaled down to fit in a phone or even a watch, to be good enough for 'the pub quiz' or for writing a gormless email.

As for the article, META does very little for the vastness of the corporation. They have gazillions of developers yet Facebook and Instagram are as boring as ever, Threads and the Metaverse are just lame and what else do they do, apart from serve ads?


Fascinating - thanks for sharing!

Now available from my gopher server which gets a lot of traffic for an "obsolete" protocol ;)

In a couple of decades running Linux installations of all flavours, I have never seen anything in lost+found!

Yea, run an old kernel with ext2 on a busy system writing a bunch of small files and have a power supply fail and you'll end up with something there.

fsck on large hard drives was scary on how long it could take to finish.


The occassional "Drive has not been checked in <n> days, forcing check" message on bootup got annoying sometimes, yeah. It could easily take tens of minutes to finish, exactly when I wanted to use the computer!

(At least this is what my memory is telling me. I could be mistaken, but that's what I remember.)


I had a largish raid back then, under ext2, may have been a massive 40G.

I recall going to sleep and it still not being done when I woke up. Bleh.


One of several reasons to partition a large volume into smaller ones. At least, back then.

"check forced", as though the machine is advising me to go look at some daemon named forced.

Forced sounds like a systemd service for Jedi stuff.

These are not the inodes you're fscking for.

I always turned this off, and also, cursed myself when I forgot to turn it off.

You need to use worse hardware and bad power :)

I used to develop SSD firmware and one of things I worked on is making it robust to power failure. The power supplies have lots of capacitance so the voltage drop was slow so we would use a special test board that would disconnect from power and discharge fast to test it.

You would flush the SSD memory to "disk", right?

When you have dirty writes in the kernel that have not yet been written to disk, in the old days of ext2 (before XFS was ported to Linux) if the power would go out, or you would have a bad disk, when fsck.ext2 would run, if files could not be matched to a directory, they would placed in the /lost+found as, and hopefully my memory is intact, as inode numbers, so you would have 1232342343, 123246564 etc and then you would have to look at each file to figure out what it was and where to move it if it was salvageable.

Brought back some memories.


The testing was at the drive level without an OS like ext2. The test was with no flush (with flush test is easy to pass). Without PLP, the pass criteria is that the data that was buffered can be either the older or newer data and not corrupted or previous data. All the other blocks on the SSD should remain unchanged. Its trickier that you think because MLC/TLC NAND could corrupt other blocks due to NAND structure and we had to deal with that. Then you also have to worry about system data in the NAND doesn't get corrupted.

Thank you for your service!

My main experience is with pre-scsi/ide systems :)

ESDI?


And more concurrent writes.

But I think ext4 will only let things appear there if you change some default flags.


Yeah, I think lack of any decent hardware RAID could be a prerequisite.

Umm .. how about a Raspberry Pi Zero 2W powered by a 2000MaH " lipstick style" powerbank?

That's what the answers are missing, of course. In some filesystem formats, it's possible either to recover completely from a journal/intent log, or at least to recover everything to the point that recovered files can be placed into the correct directory.

My SD cards have always had stuff in that folder. It scares me. I try not to look

Same here. And I had some pretty f**ed up file systems.

At one point, I had one where the directory structure was completely broken and had circles in it (broken SSD). To be fair, in that particular case, I did not look for lost+found and just wrote a tool to extract the data manually that I was looking for.

I saw it often. Running fsck on a crashed/failed partition usually does put some files in there. Maybe I kept using old hardware too long...


Have to run fsck. This used to be forced about once a month but don’t remember it happening in the last decade or so.

Quik is an abomination. I have 3 cameras including the Mission 1 Pro and am satisfied with them. I go on long mucky country dog walks and they've never let me down. Getting the content off the cameras is horrible though: no, I don't want to upload 16Gb of data to your cloud using a poor, 2-bar 4G intermittent phone connection. No. I don't want special editing effects that an only be done in app. Ultimately I pop the card out and use a USB adapter to transfer for editing, but what a pain: surely they could have produced something more user friendly?!

I don't like the app either, but it's not too hard to transfer the files directly to the phone over WiFi without using any of the cloud/editing things.

What's annoying is you have to do it in three steps: first transfer it to the app's internal storage, and then save it out to actual files, then delete the internal storage; and you need 2x the disk space.

(Another annoying thing is in some countries they just disable the 5 GHz WiFi, so transfers end up taking forever. Very annoying when traveling, and if I lived in one of those countries I would have definitely returned it)


Was that at Microsoft by any chance?


"I see Mr Smith was running in [street/location] when the explosion occurred - we'd better bring him in for questioning". Maybe the Oura doesn't record that, but if they can match other metadata with Smith's ring it could put him firmly in the frame.


>I’ve watched engineers use AI to ship in days what used to take a team weeks. Non-technical teams are now shipping production code

Good luck to those (human) teams when the briefness stuff hits the fan thanks to an AI hallucination... oh wait, the Active Individually-contributing leaders will be there to lend a hand, right?


That reminds me, I'll need to stock up on rum so I can cheer the more spectacular detonations.


Great, but what they haven't told you is that they'll probably create a subscription for the buttons. Gotta recoup those R & D costs!


That almost how you spell "palantir"...
