Powered by Feabhas is the company blog at blog.feabhas.com, writing about programming and hardware. Since 2012, 18 different Hacker News readers have linked it 43 times, most often “CMake Part 2 – Release and Debug Builds”. The last post was in 2024, but the archive is still widely read.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
HN readers link Feabhas's Sticky Bits posts on embedded C and Cortex-M hardware, such as an explanation of the ARM MPU and a piece on abusing the C switch statement. The comments cite them without judging the writing.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
The "new hardware protection mechanism called MPU available on some new ARM Cortex-M microcontrollers" is a device which lets the operating system define up to eight memory regions (sixteen on the M7), optionally with holes in them. In each region, permissions can be set for read, write, and execute, and the policy for cacheing and sharing between cores can be controlled (although this is presumably not really relev…

HN discussionIs't spagetti code a design pattern? One can make use of design patterns, clean code and separation of concerns and still get working spaghetti code without all the hacky stuff. Much less effort if use C.

HN discussionThe only modern language that gets it right is Swift: Apple did a fairly good job with unicode string handling starting in Cocoa and Objective-C, by providing methods to get the number of code points and/or bytes: https://stackoverflow.com/questions/15582267/cfstring-count-... I feel that this support of both character count and buffer size in bytes is probably the way to go. But Python 3 went wrong by trying to abs…
