jonas-won Show HN: SHAllenge – Compete to get the lowest hash

Very cool!

But same, I also was able to skip some steps as I can make some assumptions about the input as its fixed in length and doesn't need padding.

I got lucky and found a hash with 12 zeroes in 60s with my OpenCL implementation, and now I got my second spot back.

GPUs are so crazy

Thanks, I sent you an e-mail, you might need to check in spam folder, as gmail doesn't like my mail server.

jonas-won Show HN: SHAllenge – Compete to get the lowest hash

Wow 24MH/s on an i7 with 8 cores sounds really good!

I don't know how I got it working, but I'm now at 3GH/s with my OpenCL implementation. I basically converted 90% of my rust logic to opencl and now my GPU is at 100% usage and I also needed to switch to a tty, as my window manager became unresponsive haha

I'm kind of glad about this HN post, as I had absolutely no clue about how sha256 and opencl worked before this challenge.

Thanks @quirino

FWIW I got it working with rust and opencl, most of it is written by chatgpt as I have no clue about opencl. GPU usage is only 50-60% and I get 100MH/s.

With hashcat and opencl I could get 12GH/s but I couldn't find a way to use hashcat for this use case.

Mind sharing it? I have an AMD card, so its not that much of use for me, but still would be interested

I'm also yak shaving currently, as I'm using NixOS... which means spending more time looking for the correct packages and creating environments.

jonas-won Show HN: SHAllenge – Compete to get the lowest hash

At least I'm not (second place currently), I'm using a single threaded rust program that chatgpt wrote for me. I'm getting 10-15 million hashes per second.

But seletskiy is, as you can see in his nonce which tells us that he uses an RTX4090 and has 18 Giga Hashes per second. I'm really curious how he wrote that program, as I have a Rx 7900 XTX and would love to use it for this competition haha

jonas-won Depthboot – Your Chromebook, your way

One of the former main devs posted this on discord:

"Sooo here is a timeline: 1. WTT (the other core dev) left 2. I decided to also leave (see message in #announcements) 3. I gave the discord server, subreddit and github to QuantumChilliPepper 4. QuantumChilliPepper didnt really do anything, then went on a vacation, came back and went completely m.i.a. for over a month 5. Hackernews talks about eupnea 6. QuantumChilliPepper got compromised (at least eupnea email, github and discord) 7. Hacker deleted a lot of important channels and after messing a bit finally have back the server"

jonas-won Better ways to read Hacker News

On desktop I'll stick to the original page, it's so simple and good.

But it isn't that good on mobile. On mobile I use Harmonic for Hackernews it is the best one I've used. I tried many others but Harmonic is the only one I'm still using. The only reason that made me want to use another App, was that it wasn't open source, but it got open sourced some time ago.

jonas-won Unicode Character “𝕏” (U+1D54F)

HN automatically converts these urls to punycode, maybe this is a bug and it automatically converts everything to punycode even though it doesn't make sense?

jonas-won X.com (2000)

Yep, just posted this because of the price increase, will be funny to see if someone will be buying it.

jonas-won Unicode Character “𝕏” (U+1D54F)

You can also access x.com when using the Unicode Character https://xn--971h.com (𝕏.com)

jonas-won X.com (2000)

As I mentioned in another comment [0], a domain which looks like X.com but is a Unicode X https://xn--vm8a.com/ can be bought for 9,000,000 USD and I'd think that the real X.com is worth much more, as it doesn't get converted to puny code [1].

[0]: https://news.ycombinator.com/item?id=36844079 [1]: https://wikipedia.org/wiki/Punycode

jonas-won X.com (2000)

https://xn--vm8a.com/ (https://xn--vm8a.com/) which is not the twitter X.com can be bought for 9,000,000 USD This will be interesting if someone will buy it.

EDIT:

HN automatically converts to puny code that's good. The letter X in that other domain looks like this: https://www.compart.com/de/unicode/U+A4EB

You can copy and paste it and add .com and see that it is the same as the puny code URL mentioned above.

jonas-won Is Apple making implausible iPhone satisfaction claims?

Maybe my knowledge about Mail clients is a bit skewed, because I'm using open source Mail clients on every platform (Thunderbird, K-9 Mail, Evolution), and they always block External content by default. But I thought this was the standard today, but I guess loading them on the server is a bit more UX friendly instead of blocking remote content, although I wouldn't want it.

jonas-won Is Apple making implausible iPhone satisfaction claims?

Ah I didn't see that one, they mention this on another page [0] (scroll a bit down). But they mention also that it still reliably detects views and that google released a new feature a while ago "dynamic email", which automatically loads but can also be disabled.

jonas-won Is Apple making implausible iPhone satisfaction claims?

Later on they said they use Mailtrack [0]. I looked at their FAQ and they just use a tracking pixel. I don't really think that mail clients in a coorporate environment (i.e. Apple) download external images automatically. Mailtrack seems to be confident, that only 5-10% of recipients aren't "trackable" [1], but I haven't seen a mail client that by default downloads external media in a while.

jonas-won Ask HN: What is your preferred approach to mask your email address?

I self host email and have a catchall E-Mail adress.

Don't even need to create one, I just use the company name or whatever I like and then I get it automatically sorted into my directory structure with a sieve script.
