PgBouncer is useful, important, and fraught with peril
Updated 2024-09-17 to reflect updated PgBouncer support for protocol-level prepared statements 🐘 To start, I want to say that I’m appreciative that PgBouncer exists and the work its open source maintainers put into it. I also love working with PostgreSQL, and I’m thankful for the incredible amount of work and improvements that go into it as well. I also think community and industry enthusiasm around Postgres is at an all time high.

"It's this brutal fragility of vector stacks — which are used by most modern computer languages — which makes software people so wary of fully exploiting the beauty and power of recursion, and I really think that's a shame"
#Lisp

The properties of the system, and their values
Lisp is the list processing language; that is what its name means. It processes data structures built of lists — which may be lists of lists, or lists of numbers, or lists of any other sort of data item provided for by the designers of the system.But how is a list, in a computer, actually implemented?

The oceans are overheating—and scientists say a climate tipping point may be here
In 2023, the world’s oceans experienced the most intense and widespread marine heatwaves ever recorded, with some events persisting for over 500 days and covering nearly the entire globe. These searing ocean temperatures are causing mass coral bleaching and threatening fisheries, while also signaling deeper, system-wide climate changes.

Wide-field Polarization Imaging and Numerical Modeling of the Coma and Tail of Comet C/2023 A3 (Tsuchinshan-ATLAS)
Imaging polarimetry is a well-known method for analysing the structure and composition of cometary dust. Accordingly, comets are classified based on the phase angle dependent degree of linear polarization of their comae. The goal of this study is to examine the size and structure of the dust grains in the coma and in particular in the tail of the bright comet C/2023 A3 (Tsuchinshan-ATLAS) and to infer possible variations. For this purpose, we rely on the method of telescopic wide-field polarime…

Insight-HXMT Spectral and Timing Studies of a Giant Outburst in RX J0440.9 4431

Insight-HXMT Spectral and Timing Studies of a Giant Outburst in RX J0440.9+4431
The Be/X-ray binary pulsar RX J0440.9+4431 underwent a giant outburst in late 2022 and lasted three months. The Insight-HXMT has observed this source at several instances of the entire outburst in 2022-2023. We used these bright outburst observations of the pulsar to study its X-ray spectral and timing variability. The pulse profiles obtained at similar luminosity during the progress and declining phases of the outburst show a similar shape behavior.With the increase in source luminosity, the c…
