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 hash function[1], and chaining hash functions[2]. Apparently

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 obscurity since h_1 and h_2 are the actual targeted hash func

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 functions. Let h_3(x) = h_1(x) + h_2(x), h_4(x) = h_2(x) + h_1(

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 be from a different hash function, or a hash of the reversed

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 other types of propaganda. So I think

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 itself. Calling someone a "trump supporter&q

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 should reply to my second paragraph instead.

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 population, wouldn't it be reasonable to suspect that

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 trackable. Taking the detox week as an example, there wo

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.

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 that contained metadata, which I gave up on figuring out. A

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 version of the plugin wasn't (widely) used any more.

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 character.
