Freedom Embedded is a personal blog at balau82.wordpress.com about hardware and systems. Since 2010, 9 different Hacker News readers have linked it 10 times, most often “Hello world for bare metal ARM using QEMU”. The last post was in 2016, but the archive is still widely read.
Too few sampled comments (4) to say how often HN recommends it.?
Why HN links it
HN readers link this blog for its bare-metal programming tutorials, such as the ARM QEMU kernel series and hello-world posts, plus a how-to on linking binary blobs with objcopy.
Summarised by Claude from a sample of 4 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
This article[1] shows how you can use GCC toolchain along with objcopy to create an object file from a binary blob, link it, and use the data within in your own code. [1] https://balau82.wordpress.com/2012/02/19/linking-a-binary-bl...

HN discussionYeah its definitely nice to avoid an annoying "binary" to source step and then have to waste a bunch of cycles to parse/compile said source. I do embedded work and run into this all the time with C and C++. Its toolchain dependent on how to import binary blobs unfortunately in C/C++. You very quickly run into a wall on how large of a source file can be compiled around 100 MB or so. gcc is the best at handling huge s…

HN discussionI like this series; it covers getting a bare metal kernel running on ARM QEmu: http://balau82.wordpress.com/2010/02/28/hello-world-for-bare... ARM is generally a lot more sane than x86 when it comes to writing close to the metal, although there's a lot less info about stuff out there. Often reading the manuals for the chipset will get you what you want though..

HN discussionWhich part troubles you? A project like this encompasses many areas of computer science from compiler design to kernel programming. If you want to get started with doing bare metal stuff, I quite like this article: http://balau82.wordpress.com/2010/02/28/hello-world-for-bare... It uses ARM so you don't have to worry about all the x86 legacy cruft.
