P-computers can solve spin-glass problems faster than quantum systems
“To solve this problem required us to build p-computers at sizes we had never gone to before,” Çamsarı said, “We used millions of p-bits and then did simulations on CPUs to see how they will behave at much larger scales, using existing chips that we customize.” The idea to use so many p-bits came accidentally. […]
Locks in PostgreSQL
We’ve already discussed some object-level locks (specifically, relation-level locks), as well as row-level locks with their connection to object-level locks and also explored wait queues, which are not always fair. We have a hodgepodge this time. We’ll start with deadlocks (actually, I planned to discuss them last time, but that article was excessively long in […]

Scala 3 slowed us down?
Is this clickbait? Not really. Is this the fault of the language or the compiler? Definitely not. Rather, it was part of a rushed migration. Sharing the lessons learned in the process. I was refreshing one of our services. Part of this process was to migrate codebase from Scala 2.13 to Scala 3. I’ve done […]
Dollar-stores overcharge cash-strapped customers while promising low prices
On a cloudy winter day, a state government inspector named Ryan Coffield walked into a Family Dollar store in Windsor, North Carolina, carrying a scanner gun and a laptop. Inside the store, which sits along a three-lane road in a county of peanut growers and poultry workers, Coffield scanned 300 items and recorded their shelf […]
Goodbye, Microsoft: Schleswig-Holstein Relies on Open Source and Saves Millions
(Bild: Imilian/Shutterstock.com) Schleswig-Holstein saves 15 million euros in license costs by migrating from Microsoft to free software. The conversion is significantly cheaper. The state administration of Schleswig-Holstein is making a remarkable U-turn in its IT strategy and consistently relying on open source [1]. After the migration from proprietary Microsoft software to free solutions was initially accompanied […]

The Anatomy of a macOS App
Programs running in windowing environments, applications as we used to know them, have more complicated requirements than those run from a command line. Rather than embed all the resources they require for windows, menus and the rest in a single file, Mac OS broke new ground by putting those into resources stored in the app’s […]
Google Titans architecture, helping AI have long-term memory
The Transformer architecture revolutionized sequence modeling with its introduction of attention, a mechanism by which models look back at earlier inputs to prioritize relevant input data. However, computational cost increases drastically with sequence length, which limits the ability to scale Transformer-based models to extremely long contexts, such as those required for full-document understanding or genomic […]
Java Hello World, LLVM Edition
After exploring Java bytecode in previous years (2022, 2023, 2024), this year we’ll take an unexpected detour for a Java advent: instead of generating Java bytecode, we’ll use Java to build and execute LLVM IR, the intermediate language behind compilers like clang. Using Java’s Foreign Function & Memory (FFM) API, we’ll call the LLVM C […]
