Re:Show HN: SHAllenge – Compete to get the lowest Hash on Monday June 17, 2024 @12:24AM (#40702282)

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.

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

Re:Show HN: SHAllenge – Compete to get the lowest Hash on Saturday June 15, 2024 @12:02PM (#40690579)

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

Re:Show HN: SHAllenge – Compete to get the lowest Hash on Saturday June 15, 2024 @10:11AM (#40689941)

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

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"

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.

Re:Unicode Character “𝕏” (U+1D54F) on Monday July 24, 2023 @08:31AM (#36846919)

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?

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

Re:X.com on Monday July 24, 2023 @03:21AM (#36844133)

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].

Re:X.com on Monday July 24, 2023 @03:12AM (#36844079)

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.

Re:Is Apple making implausible iPhone satisfaction claims? on Thursday July 13, 2023 @05:08PM (#36716011)

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.

Re:Is Apple making implausible iPhone satisfaction claims? on Thursday July 13, 2023 @05:05PM (#36715971)

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.

Re:Is Apple making implausible iPhone satisfaction claims? on Thursday July 13, 2023 @02:35PM (#36713988)

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.

Re:Ask HN: What is your preferred approach to mask your email address? on Friday July 07, 2023 @06:49PM (#36639287)

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.
