After finding the right search terms (concatenating hash functions), I found a few stackexchange discussions about this, which lead me to other methods like truncating a stronger h…

I suppose I missed the assumption that h_0, h_1 and h_2 cannot be trivially decomposed into concatenations of other hash functions, whereas h_3 and h_4 can. Also, there's no obscur…

I will try to show the difference between one 256-bit hash function and two 128-bit hash functions. Let h_0(x) be a 256-bit hash function. Let h_1(x) and h_2(x) be 128-bit hash fun…

Other than using a stronger hashing algorithm that produces longer hashes, would there be any advantage in storing two or more separate hashes of an object? The extra hashes could …

I tried translating with Baidu and it comes up with "宣传" and "鼓吹". The latter seems more appropriate for propaganda that puts something in a positive light, but doesn't apply to ot…

Calling someone a "WuMao" is saying that the person is PAID to support the Chinese government, regardless of their actual opinions, and the target of support isn't in the term itse…

No I don't have evidence, and I was going to include that I don't have evidence in my comment, but didn't. I was merely stating a possibility in answer to your question. Maybe you …

Maybe because there might exist propaganda against the Chinese government? If Twitter has evidence for Chinese propaganda on a US-based site that's inaccessible to the Chinese popu…

Currently, SCMP is not accessible in China.

I mistakenly thought of the change as a software change, since I've yet to use the flag button. It might be useful to tie changes in community standards to something concrete and t…

I think there will always be resistance to change, so perhaps there should be a visible indication that some idea is being tested out, with an option for users to disable it.

This came up in the openbsd-misc mailing list yesterday[1]. Someone also mentioned the link that elchief posted. [1] https://marc.info/?l=openbsd-misc&m=148105687011923&w=2

Last year I reversed engineered a (36KiB) Windows PE binary[1] to obtain C++ source code that compiled to almost the exact same bytes. What stumped me was an undocumented section t…

If you are using GNU screen, you can also see how each "frame" is drawn by looking through the scrollback buffer.

Did you consult the plugin author before blogging about the vulnerability? Is there a reason why you blogged about it a year later? I am guessing that you waited until the old vers…

Are you referring to UTF-8? If so, this is misleading as you can encode up to 2^21 + 2^16 + 2^11 + 2^7 = 2,164,864 code points, which is not the same as encoding bytes in a single …

It seems like users are not anonymous, but this lead me to the concepts of overlay networks[1], darknet[2], and mesh networks[3]. Thanks for that. [1] https://en.wikipedia.org/wiki…
