All you need is links
When Tim Berners Lee talks about how he designed the web, he uses an analogy from physics, describing his process as a quest to find “fundamental laws” which can generate a desired system:

System memory allocator free operation zeroes out deallocated blocks in iOS 16
The system memory allocator free operation zeroes out all deallocated blocks in iOS 16.1 beta or later. Invalid accesses to free memory might result in new crashes or corruption, including NULL -pointer dereferences and non-zero memory being returned from calloc .

Two Years of Life with PinePhone
On June 9th, 2020, early into a still raging pandemic, I received my PinePhone UBports Community Edition. It's incredible how fast these two years went by, and how much the PinePhone experience improved in the meantime. This is just a subjective post about what I remember, you may also consider it a

Ventura Issues
I’m more surprised by the nature of many of these issues, by how ridiculous they are compared with the sheer age and supposed maturity of a 20+ year-old operating system.

Abstraction: Not what you think it is
What abstraction really means in programming, from PL theory, by Jimmy Koppel: why functions, interfaces, and indirection are not abstraction.

A lock-free, concurrent, generic queue in 32 bits
While considering concurrent queue design I came up with a generic, lock-free queue that fits in a 32-bit integer. The queue is “generic” in that a single implementation supports elements of any arbitrary type, despite an implementation in C. It’s lock-free in that there is guaranteed system-wide progress. It can…

Galois field instructions on 2021 CPUs
CPUs like to operate on data types such as uint8_t , uint16_t , uint32_t , and uint64_t . These data types can be viewed as integers modulo 2 8 , 2 16 , 2 32 , and 2 64 respectively. Addition and multiplication can be defined on these integers modulo 2 N in a way which is familiar to most people; for example, in…

Verifying distributed systems with Isabelle/HOL
We use distributed systems every day in the form of internet services. These systems are very useful, but also challenging to implement because networks are unpredictable. Whenever you send a message over the network, it is likely to arrive quite quickly, but it’s possible that it might be delayed for a long time, or…

Verilog Is Weird
Verilog is the most commonly used language for hardware design in America (VHDL is more common in Europe). Too bad it's so baroque. If you ever browse the Verilog questions on Stack Overflow , you'll find a large number of questions, usually downvoted, asking “why doesn't my code work?”, with code that's not just a…
