I just wrote a post about this kind of stuff and why it's (almost always) nonsense. You will spend more time and effort trying to shoe-horn SQLite into a server database than you will ever get any benefits from. https://ben

Or like saying that C++ was somehow deficient just because NodeJS had to be created in order to script v8.

I've used OpenResty extensively which is basically just nginx + luajit with a lot of additional APIs and features. The nginx-lua-module is available separately from the OpenResty distribution of nginx, so you can just install and run

This is already available as an optional Lua target in mlua [0]. I recently built a programmable server for Server-Sent Events scriptable with Lua [1]. I chose Lua 5.4, but it's trivial to switch it to LuaJIT, or really any other Lua

JSON is a textual encoding no different than CSV. It's just that people tend to use specialized tools for encoding and decoding it instead of like ",".join(row) and row.split(",") I have seen people try to build up

LuaJIT.org stopped publishing release tarballs [1] which caused leafo's GH actions builds [2] to suddenly stop working. The workaround was to start testing against OpenResty's distribution of LuaJIT [3] which is incompatible with

For streaming in VR it has to be at least 4K per eye. So 8k in the general case, but realistically it will be higher than that. Nobody can stream 2x 4K to my Apple VR headset. I can barely get a single 4K stream to my TV!

VR tech still isn't ready yet. It needs very high-res video streams which basically no internet provider/CDN can offer at scale. 40Mbps+ HEVC just isn't scalable. So the only content is whatever can be downloaded to the dev

+1 to the completions/inferences in Zed. It's the first editor that I feel (mostly) confident about just tabbing-through the AI completions with minimal prompting/re-editing.

You're a legend. Thanks for writing The Book. It really affected my life in a very positive way.

Probably the worst PK index of all time. There's a reason why it's barely ever used.
47.
by benwilber0 2y ago
Maybe? idk. Not in Postgres. The default index is a B-Tree. A hash-based index would be terrible for disk-seeking, in any case.

You only need 1 index on the UUID. Instead of everywhere the UUID is referenced from other tables
49.
by benwilber0 2y ago
This is why you should _never_ make your UUID column the primary key. For one, it's enormous. Now you have to copy that 128bit int to every side of the relation. Two, in most cases it's completely random. Unless you had the foret

I had such a bad experience with Mongo DB back in 2012-2013 that I don't think I'll ever use it again, or even really consider it. But maybe it's changed and gotten better since then? Anyway. I just use Postgres.

Postgres can scale to millions of users, but Rails definitely can't. Unless you're prepared to spend a ton of money.

I've loved and used SQLAlchemy for many years. It got me a long way in my career. But at this point I've sworn-off using query-builders and ORMs. I just write real, hand-crafted SQL now. These "any db" abstractions j

Do you think that you could get Google, or Github, to turn off your 2FA login requirement if you really needed it? Like if you lost your codes? Or never saved them in the first place?

Author here. Explain to me why I should be permanently banned from Uber because I accidentally forgot the secret key to log in to my account.

How many backups of my Uber codes should I have had? If I have 0, does that mean that I can never get a car to take me to the airport again?
