interesting to see this forum show-up again.
remember 15 years ago there were posts about DYI drone from some random guy with lots of theoretical physics about stable conditions derivations. it got a lot of criticism. now looking back and following what DJI is doing with sensors, his approach was totally wrong and that community nailed it with feedback. the forum got some extravagant ideas and some worthy criticism. at least back then.

I remember visiting this site daily 10-15 years ago, in russian, ofc. The moderation was super high, karma system worked great, the content quality was astonishing. Then they switched up owners, tried heavily monetizing corpo-pseudo-blogpost-marketing crap and it all went downhill from there

habr is an institution. it's like the "runet hn", minus wild west vc ecosystem, plus integrated blog posting like lj ogs intended to. probably helps a lot with original work like TFA getting traction. more power to that!
runet sites of that era are often born out of the hacker's characteristic contrarian attitude "because we can". attempts to monetize them in more recent years are bound to accomplish little more than fuck up the content quality and/or the "owner cashes out and opens cafe" thing.
nevertheless, to this day, when i think habrahabr, i think way higher bar for technical competence than hn. it's all in the attitude.

It went downhill when they allowed getting an invitation via single blog post, requiring just one person to like it enough to give an invitation. Which wasn't hard to write - just translate something popular from hackernews before anyone else does it.
Shortly after, it became hilariously easy to farm and manipulate karma balances across the entire site. With 50 accounts (mults or real people all the same) you could create a new account a day.
Monetization started when it was already in a death spiral.
Re: 6NF File Format
#7Looks interesting, but few comments on the forum & even a negative vote count ATM. Format kinda looks "old school" in terms of defining records, but I guess that can be a positive in some circumstances?
Re: 6NF File Format
#8This format requires temporal validity with `valid_from`, but doesn't include `valid_to`. I don't understand how `valid_from` and the also required `recorded_at` interact.

I don't have any additional insight to the format, but I think the idea is that there is an implied ->infinity on every date range. Every bank can only have one bank_name so multiple bank_names for the same bank entity can be sorted on the 'valid' and 'recorded' axes to find the upper bounds of each.
Re: 6NF File Format
#10Improvement idea -- in my experience "valid_from" is always a date (no time, no timezone). That's how it's reported in documents (e.g. contract validity period).
Rows that need seconds (e.g. bank transactions) are events, they aren't "valid" from a particular point in time forward, they just happen.
