Callbacks are Pretty Okay
Among the many proposed solutions, one of them strikes me as particularly clean: "asynchronous wait" or "wait and defer". iced-coffee-script had this a while ago. Kal just debuted with an identical solution, only differing in syntax. Supposedly LiveScript supports this with "backcalls" .

You Can't Always Hash Pointers in C
Occasionally I’ve needed to key a hash table with C pointers. I don’t care about the contents of the object itself — especially if it might change — just its pointer identity. For example, suppose I’m using null-terminated strings as keys and I know these strings will always be interned in a common table. These…

Reading code is a skill (2020)
I’m inspired to write this post because Someone Is Wrong On The Internet. Of course a more accurate statement would be “I disagree with some aspects of what someone on the internet said, even though they have an entirely valid point of view”. But that’s less catchy. I saw a Tweet I violently agreed with, so I…

Systems that no one will test
(this post figured on HNews here) This happened to me in 2020, and it has been on my mind again lately. During the worst of the pandemic, I found a vulnerability in a system that gave me access to the Brazilian federal system, and with that access I was able to retrieve information on any

Algorithms Are Now Commodities
When I first started writing software, developers had to implement most of the algorithms they used; yes, hardware vendors provided libraries, but the culture was one of self-reliance (except for maths functions, which were technical and complicated).
