Hennecke seems to be just one of many "udarniks" [1], common in countries east of the iron curtain. There isn't really a lineage between that and contemporary capitalist culture IMO. [1] https://en.wikipedia.org&#x

Isn't it trivially [1]?

I jokingly alluded to antirez as HN crowd pars pro toto. I agree it doesn't pass as an intellectually honest argument.

Sorry boss, I'm just tired of the debate itself. It assumes a certain level of optimism, while I'm skeptical that meaningfully productive applications of LLMs etc. will be found once hype settles, let alone ones that will reshape

I wouldn't trust a taxi driver's predictions about the future of economics and society, why would I trust some database developer's? Actually, I take that back. I might trust the taxi driver.

I'm really confused because I had to scroll half the comment section for the word `semaphore`. This seems to be an interview question about JS esoterica, not concurrent programming.

The "4j" suffix literally means "for Java" and is commonly used to indicate that the project is a Java library, e.g. log4j, slf4j, &c.

What you're really saying is that the database presented in OP is not useful because it only handles DQL. 1. SQL can be thought of as being composed of several smaller lanuages: DDL, DQL, DML, DCL. 2. columnq-cli is only a CLI to a que

I'm curious why do you think of DAX as a virtue. My poor SQL-shaped peg brain has never really fit the DAX hole of MS software. Also, it always struck me as something too complex for the non-technical folks, and not expressive enough f

This book exposed me to proper math back in high school, I liked it.

Huh, even though I would prefer a universal SQL layer, ibis looks quite nice.

TIL there's an actual 'botched' library with the same name; I actually came up with it independently on a lazy office afternoon :^)

That's what I do at $dayjob whenever I have to do windowing &c. Figuring out this stuff in Pandas is a waste of time. Before I discovered DuckDB, I would re-learn the API every damn time. I came up with a little utility function, w

I like interface-only packages in the Julia ecosystem e.g. Tables.jl enables the development of several packages for querying tabular data that work across many concrete implementations; Plots.jl separates the high-level plotting interface

DuckDB and Polars are my bets in the Python data-wrangling space. I grew tired of Pandas' weird-ass API.

I have found this setting to break some apps (e.g. Spotify, my bank's app) though.

Neither did I. I tend to avoid RBDMS-specific syntax extensions of questionable benefit. The only thing I really miss in PG is ASOF JOIN. It's possible to implement it via CROSS JOIN LATERAL, but in my case it resulted in nested loops

Related — Postgres (other RDBMS's too, probably) has JOIN b USING (column, ...) and NATURAL JOIN. IIRC, both fail when there's ambiguity in column names.

Nice one!

Also, you will sleep better at night knowing that your column dtypes are safe from harm, exactly as you stored them. Moving from CSV (or god forbid, .xlsx) has been such a quality of life improvement. One thing I miss though is how easy it

I use WireGuard with a server in my pantry as a router. Dynamic IP of the server is handled by DuckDNS, and WireGuard gracefully handles client roaming e.g. I can switch from home wifi to mobile internet without interrupting my SSH sessions

If you like fzf, give skim [1] a go. It's basically faster (anecdotally) fzf, but can also be used as a Rust library. I made a little personal to-do manager using it, together with SQLite for persistence. I also improved my fish shell

I use GNU Stow with a dotfiles git repo placed in $HOME. Works well.

Dependent types could presumably capture this idea. They are very expressive – see [1] for a perfectly type-safe printf implementation in Idris. [1]: https://gist.github.com/chrisdone/672efcd784528b7d0b7e17ad9c...

Nice spelunking! If there is hope of avoiding C++ altogether, then I'll try testing it again on something beefier than my laptop. Thanks for taking the time and effort.

That's a nice and tidy codebase, real pleasure to read. > I believe many (most?) opencv & numpy operations release the GIL. Any idea how I can determine this? I am prototyping a real time machine vision application targeting 2x7

Regarding [1], many OpenCV functions in Python support an optional dst argument, similar to how they do in the C++ API. This makes the memory management situation not completely hopeless. In my experience, the only drawback of the Python AP
