> you have two options There are many other ways to allocate capacity. For example, you could give preferential access to customers who sign long-term purchase commitments, or some…

Faster is better than slower. Postgres is amazing. When I use Sqlite I miss many of its upsides--better data migrations and better concurrency being two. But queries are not free, …

> every few millennia We'll feel awful silly having made any leap seconds if the robots kill us all in the next decade. More seriously -- all of today's computers and probably all …

I had an issue in a CI pipeline once where clocks on two different machines drifted out of sync, and it looked like an HTTP request went back in time (it had some validity from now…

One way of thinking about ignoring leap seconds is that it's like letting the effective prime meridian drift east/west. And a "leap hour" is kind of like a timezone change. In fact…

Occasionally in pure python "asymptotically reasonable, simple implementation, terrible memory locality" is the right pick for a data structure. You want to avoid an extra linear t…

I guess to expand on my earlier post, it's generally a good thing that these kinds of absurd allegations are counterproductive and generally not convincing, because if they were mo…

This hyperbole does more to turn people away from Bluesky and other sites more than X to be honest. There are clearly lots of politically moderate, wholesome "politically inert," a…

Yeah I guess a c++ programmer might say `std::array::operator[]` is a function (or method, whatever), just like `std::array::size` is. And that identifying the array with just one …

I wonder if "the right solution" is a programming language that is fast, concise, trivially easy to run, and outputs some efficient binary format like protobuf. Programming languag…

"Easier" is probably the right one-word generalization, but worth noting that there are quite different challenges. Stopping distance is substantially greater, so "dead halt" isn't…

There's an Amdahl-like effect, where "100x slower" means that anything nontrivial in pure python ends up being fat in your flamegraphs, even if your "heavy lifting" core algorithmi…

For compute-heavy code "100x slower than C++" is a good rule of thumb in my experience in python 3.10.

Many simple scripts at my work that more or less just argparse and fire off an HTTP request spend half a minute importing random stuff because of false deps and uncommon codepaths.…

For cloud jobs that can be true, but for single threaded dev-in-the-loop work you can't just buy a 100x faster processor than the one on their dev machine, and the latency is expen…

This might have been your experience, but mine has been very different. In my experience a typical python workload is 50% importing python libraries, 45% slow python wrapper logic …

Yeah, I think the "paradox" is usually a problem for pundits and academics and not practitioners. Lots of people have experience finding and correcting market inefficiencies, usual…

A system of n experts is no different to a single expert wrt the NFLT. The theorem is entirely indifferent to (ie "equally skeptical of") the idea.

Releasing an open source product that improves on alternatives doesn't sound like ”stealing” or ”adding no value" to me. They're giving away something valuable, same as the people …

I wonder about the global statistics of sorted data... Is the most common number of elements to sort zero? Certainly less than ten? What about the median? Two elements to sort? One…

It's the bank. One of the biggest US retail banks. Maybe other big ones don't, maybe I should change banks.

I have great credit and my bank charges me $3 every month to pay my rent. (They will send a cheque in the mail for free, but it wasn't reliable for me so I stopped doing that.) Thi…

For this sort of change I think the best strategy is "two passes". Auto-format those O(30k) files and get global approval. Then, separately, make your two-line semantic change and …
