Making Postgres slower

news.ycombinator.com Jacob Jackson 2026-01-03 16:12:59

July 27, 2025 Everyone is always wondering how to make Postgres faster, more efficient, etc, but nobody ever thinks about how to make Postgres slower. Now, of course, most of those people are being paid to focus on speed, but I am not (although, if you wanted to change that, let me know). As I was writing a slightly more useful guide, I decided someone needed to try to create a Postgres configuration optimized to process queries as slowly as possible. Why? I am not sure, but this is what came o

“That is quite unusual,” said a third private intelligence figure, adding that in the U.S. people are “very open” about having worked for the CIA. America has a “semi-retirement model where when you’re moving out of the agency, you’ll probably spend about six or seven years subcontracting back, and then you’ll finally move into the private sector.” “We don’t do things like that here at all. So, Vauxhall [MI6] will almost never outsource meaningful intelligence work to the private sector,” they

Nearly 4,000 NASA employees have opted to leave the space agency through the Trump administration's deferred resignation program, NASA said on Saturday.

Teach Yourself Programming in Ten Years (1998)

Why is everyone in such a rush? The conclusion is that either people are in a big rush to learn about programming, or that programming is somehow fabulously easier to learn than anything else. Felleisen et al. give a nod to this trend in their book How to Design Programs, when they say "Bad programming is easy. Idiots can learn it in 21 days, even if they are dummies."

Ageing accelerates around age 50 ― some organs faster than others

Ageing of many tissues accelerates around age 50, according to an analysis of tissues in people ranging from teenagers to individuals in their sixties.Credit: Karen Haibara/AFP/Getty It is a warning that middle-aged people have long offered the young: ageing is not a smooth process. Now, an exhaustive analysis of how proteins change over time in different organs backs up that idea, finding that people experience an inflection point at around 50 years old, after which ageing seems to accelerate.

In sledgehammer every operation is encoded as a sequence of bytes packed into an array. Every operation takes 1 byte plus whatever data is required for it. Each operation is encoded in a batch of four as a u32. Getting a number from an array buffer has a high constant cost, but getting a u32 instead of a u8 is not more expensive. Sledgehammer bindgen reads the u32 and then splits it into the 4 individual bytes. It will shuffle and pack the bytes into as few buckets as possible and try to inline
