hackernudes··on An Embedded Linux on a Single Floppy
Probably only used the floppy to boot into a ramdisk.

hackernudes··on Twenty One Zero-Days in FFmpeg
That's not really true. Ffmpeg is a Swiss army knife for anything related to digital multimedia (old and new). It is broken into a few libraries but doesn't really have plugins.

Gstreamer has a different model, chaining together plugins. Lots of overlap, but I think Gstreamer only has real traction because some silicon vendors use it.

> if solar panels drop another 90%, why not just slap them on earth?

Because you need batteries then.

hackernudes··on Ask HN: What are tools you have made for yourself since the advent of AI?
I have been thinking of this for a few years! Nice, I will check it out.
hackernudes··on Why are so many young people getting cancer?
Organic farming still uses pesticides.

See https://www.epa.gov/agriculture/organic-farming - "Pesticides derived from natural sources (such as biological pesticides) may be used in producing organically grown food"

hackernudes··on We Uncovered a Hidden Wealth Transfer in the SpaceX IPO. You're Holding the Bag [video]
I didn't watch the whole video, but the quick summary is that because of passive investing (index funds in 401ks, etc...) lots of regular people will end up owning SpaceX stock even though they didn't explicitly buy it.

I think the hate about this idea is unwarranted.

hackernudes··on Apple reportedly preps native support for Google Cast in iOS 27
It's really not a replacement for Google cast. It requires actively encoding video to send over wifi. If it's anything like wireless Android Auto it will eat a lot of battery. Google cast is usually a tiny payload to the device to start playing some URL from the Internet.
hackernudes··on A new book about humanity's obsession with gold

Article is a brief review of the book "The Secret History of Gold" by Dominic Frisby.

hackernudes··on SpaceX wants to launch a million satellites
Pretty sure they mean that Starship is not working reliably yet
hackernudes··on SpaceX wants to launch a million satellites
isn't the IPO a way to get tons of money?
hackernudes··on Motherboard sales are now collapsing amid unprecedented shortages fueled by AI
Will demand for computing ever go down from where it is now? Even if the AI bubble temporarily pops, in the long run I think the demand for computers will be practically infinite.

Market forces will probably bring the price of hardware down in the next decade. Whether it is in a form that is useful for regular people/hobbyists is another question. If not, then hopefully the "cloud" starts to look a lot different.

hackernudes··on Copy Fail
I've read many CVEs (somehow that acronym is ok... heh) but have never seen LPE despite being familiar with the concept.

RTA = restricted to adults
hackernudes··on Copy Fail
LPE = local privilege escalation

Too many darn acronyms. This one wasn't too hard to figure out from context but I wish people would define acronyms before using them!

XCursor (Linux nerds know)
hackernudes··on Scientists discover why bread can cause weight gain without extra calories
I may be missing something, but isn't the focus on calories about weight gain, not feeling full?
hackernudes··on Bitcoin miners are losing on every coin produced as difficulty drops
You left off the critically important part of the quote, IMO...

> ... according to Checkonchain's difficulty regression model

It's a guess based on oil costs (as a proxy for energy costs). Personally I think it is completely worthless.

hackernudes··on CSS is DOOMed
It was a traditional plugin (NPAPI), not NaCl (Native Client). Honestly a total gimmick. I still play Quake Live, though!
hackernudes··on Modernizing swapping: virtual swap spaces
I do wish I had documented what I tried better! There might be a magic combo that could have helped but I tried tweaking a lot of the vm settings.

One day I will probably see if I can still reproduce the original problem and be more methodical about it. More likely on list of things I might not ever get around to.

hackernudes··on Modernizing swapping: virtual swap spaces
I see some comments about soft lockups during memory pressure. I have struggled with this immensely over the years. I wrote a userspace memory reclaimer daemon and have not had a lockup since: https://gist.github.com/EBADBEEF/f168458028f684a91148f4d3e79... .

The hangs usually happened when I was stressing VFS (the computer was a samba server) along with other workloads. To trigger a hang manually I would read in large files (bigger than available ram) in parallel while running a game. I could get it to hang even with 128GB ram. I tweaked all the vfs settings (swappiness, etc...) to no avail. I tried with and without swap.

In the end it looked like memory was not getting reclaimed fast enough, like linux would wait too long to start reclaiming memory and some critical process would get stuck waiting for some memory. The system would hang for minutes or hours at a time only making the tiniest of progress between reclaims.

If I caught the problem early enough (just as everything started stuttering) I could trigger a reclaim manually by writing to '/sys/fs/cgroup/memory.reclaim' and the system would recover. I wonder if it was specific to btrfs or some specific workload pattern but I was never able to figure it out.

hackernudes··on Jensen Huang says Nvidia is pulling back from OpenAI and Anthropic
Doesn't that show physical cash in bank vaults? Am I misunderstanding? That number would be utterly meaningless for this discussion.

Edit: I see this was covered in other replies

hackernudes··on DialUp95 – A 90s inspired nostalgia hit
https://m.youtube.com/watch?v=xalTFH5ht-k&t=99

This matches my memory of 56k dialup with the two BONGs.

And now I get to share my favorite AT command. M0 could mute the modem! M1 was quieter than the default. I will never understand why those weren't more common! Used like: ATM0DT

hackernudes··on Officials Claim Drone Incursion Led to Shutdown of El Paso Airport
Today I learned: Man-portable air-defense systems (MANPADS) are shoulder-fired, surface-to-air missiles designed for use by individuals or small teams to engage low-flying aircraft, helicopters, and UAVs.
