Why choose this username for HN?

It's the same as the one I have in another service, but cut short because HN has (had?) a 16 character limit.

To be fair it still is a single word with no numbers or special characters, just not a short one.

Whoa - I think we need to be cautious about dismissing genuine concerns around being deepfaked as just victimhood. The issues surrounding deepfake porn are complex than that - they can have significant psychological impact on individuals.

Also we really can’t ignore the lack of consent and the abhorrent violation of someone's image. This can’t be boiled down to growing “thicker skin” - there’s pretty major ethical considerations as well as the potential harm it can cause to a person's reputation and mental well-being.

The knowledge that the neighbours next door are having gay sex might cause a significant psychological impact on a hyper religous couple, but nonetheless wedo and should ignore that impact as it cannot be mitigated without infringing on important freedoms.

Nice job with the map! It was great seeing your presentation at symposium!

Thanks for sharing, that situation is not great and you did the right thing. One a side note, is your username a reference to the University of Waterloo?

UW is my alma mater but I also grew up in Waterloo.

Are you guys hiring any interns this summer/fall?

Any internship positions available?

Hi Colin, I’m curious as to how you search repeated letters through ngram index? I understand the example search with the string “limits” (find intersection of “lim”, “imi”, “mit” and “its”). However, if the user wants to search the string “aaaaa” how would you go about searching that?

Good question. We still construct ngrams for it, exactly the same way. So for example, we might extract `aaa`, `aaa`, and `aaa`. Or we may extract `aaaa` and `aaaa`, or perhaps `aaaaa`. Then we deduplicate to find the unique ngrams and look them up in the index.

So it's possible that a document containing `aaa` might match our ngram search, but we double check after retrieving them and exclude them from the result set.

Interesting stuff, was curious how they search repeated letters through ngram index? I understand their example search with the string “limits” (find intersection of “lim”, “imi”, “mit” and “its”. However, if the user wants to search the string “aaaaa” how would they go about searching that?

I can't answer any of your other questions but Obsidian is owned by Dynalist, which is based in Oakville, Ontario, Canada. Their OCN number is 2538019 if you want to search them up, they're also on CrunchBase https://www.crunchbase.com/organization/dynalist
