Yeah the ratio 10:1 seems reasonable from my experience, and the order-of-magnitude difference is consistent with the 80:20 rule of software engineering that states that the last 20% of work on a project take as much time as the first 80% o

There are, but they are not state of the art. There is also the benefit of the spam filter service being "live updated," e.g. if a new type of spam message comes up it will get flagged since lots of users.

I like the simplifying-the-problem approach a lot! Roads in the US/California are so good that I can see it happen, and with clear labelling this could totally "ship" in a few years (i.e. remove the safety driver). The next s

This makes me want to try Go, though I wonder how long it would take to develop the same "fluency" and knowledge of which library to use. It would be exiting to have things run fast though... One minor plug `pyflakes` is very good

I hear you. I think most phones/chipsets are supported by lineage, but it's really hard to know which image to download... I've been using CopperheadOS and very happy with it. Android + updates w/o anything G in sight...

Very good point about reading/verbalizing symbols and notation. Once you know what they mean, they are super useful for expressing complex concepts precisely and compactly, but when you're getting started they look like an alien l

Thx for the pointer to TMX. I need to do some computer-aided translation, and was about to roll my own file format for parallel-strings, but always better to choose something existing. Seems there is quite a bit of tools that support it too

Awesome read! It's great to see someone faced with tech challenge and not back down. We need more of that. For anyone interested, here are some links to the details of error-correcting codes (ECC) used on CD-ROM: - http://w

IMHO, the only valid reason for "roll your own" is if the application needs 50x+ performance than what would be possible using existing solutions (as is the case described in this blog post). Otherwise follow the rules: The three

Yep, it's essentially the same thing. I guess EAV approach was the old way from before JSONField days. In both cases the cost of this flexibility and migration-less data model extensibility is extra code paths and guards to check if th

This is very useful if you want to ship new features without constantly changing DB tables by adding new fields to models. Example scenario: - Year 0: ship v1.0 of software with EAV table in place - Year 1: a few months later you need to st

See my comment above where I plug my book. Just out of curiosity, what was the problem with Khan Academy? Was it the video format, the pace of explanations, or something else?

I like that it shows the DL tool used. Might be good for people learning to see some state-of-the-art stuff before choosing a framework. See also http://www.gitxiv.com/ which seems similar.

Wow, this is going to be awesome for creating reports and solutions. Can use jupyter to quickly find solutions (e.g. using SymPy) then do the writeup in .tex with includes. Good job!
