The trick would be to find some financial instrument that lets you short BTC, or make prediction-market bets on a falling price.

You haven't fixed much, you're linking to a real paper now but it's about SHA-1 collisions.

I looked into citation [5] since it sounded interesting but the DOI link has been hallucinated and goes to some other article. I assume many of the others are similarly bogus.

By which peers?

Also, a collision on single-sha256 would imply a collision of double-sha256 right off the bat, since the inputs to the second round would be matching. But as you say, a collision attack doesn't do much to BTC mining.

If you can't tell the difference between MD5 and SHA-256, you should not be making claims such as the one in the title.

I believe I hold the actual record for most colliding bits in full-round SHA256 (72% of bits matching). My proof fits in a tweet, why doesn't yours? https://news.ycombinator.com/item?id=38668893 (Also my work does no

I'm intrigued, unlike most slop they don't seem to be trying to sell anything, and it doesn't have most of the superficial tells. We'll find out if https://alexandmanu.com/photos/ ever exists. Edit:

Used hardware is always going to be a better deal than something brand new. You can get a used M1 MacBook Pro for a similar price to a new Neo, and that will blow it out of the water on all axes except bursted single-core CPU perf. And it&#

How do you actually use HLS in the form of a native browser feature? Can you just put the m3u8 in the video src?

Preventing computer-based cheating in competitive chess is a big deal (and I assume go also), because spectators tend not to want to watch two computers playing against each other.

I set my camera to save both JPEG and RAW. 95% of the time the camera's JPEG is fine so I just use that (maybe with some final adjustments in GIMP), but it's nice to have the RAW around in case more significant edits are needed.

That's a confusing perspective of ASLR

Good point! (another reason not to use global state heh)

> Unlike dlopen-based plugin systems, threadprocs run traditional executables with a `main()` function. Why not dlopen with something that calls plugin_main() (etc.) in its own thread?

It didn't read that way, to me.

PIO is unsuitable for FPGA impls, that's what the article says. > If you’re thinking about using it in an FPGA, you’d be better off skipping the PIO and just implementing whatever peripherals you want directly using RTL.

I also spent a long time trying to do the glitching with a mosfet, but never got it to work. I couldn't get enough drive strength to actually glitch anything, without messing with the delicate capacitance+impedance tolerances of the bu

The CRDT isn't syntax-aware either

by Retr0id 7mo ago
Why is that valuable?

by Retr0id 7mo ago
If semantics-layer conflicts still have to be detected somehow, and resolved by hand, what value is the underlying CRDT providing?
989.
by Retr0id 7mo ago
Yes. There are many ways to instantiate a CRDT, and a trivial one would be "last write wins" over the whole source tree state. LWW is obviously not what you'd want for source version control. It is "correct" per its
