Companies with investors are evil Updated 2025-07-16
They may have nice looking save the world charity campaigns, but once you get even close to affecting their revenue stream, the axe falls. The charity is only a publicity stunt to reduce wages.
Some level of government intervention is needed to control investor's greed.
It is just a question of business model: some business models are eviler than others. Making people pay for operating systems being possible the most evil of all.
One thing must be said however. You can learn a lot by working in a good company, because it ends up putting you in contact with practical real problems that you wouldn't otherwise see by just doing your own random low-tech startup. This is especially valuable if said company is also enlightened enough to use and contribute back to open source software, thus improving the world and paying back the moral debt of using other people's work for free.
Another important point to consider is who in the company is evil. In a sane tech company, the lowly engineers are going to be non-evil. And then the more you go up the management chain, the more aligned you have to be with investors, and thus the more and more evil you get. HR is just evil from the bottom though, it's just the nature of their job.

Compile MicroPython code for Micro Bit locally Updated 2025-07-27
To use a prebuilt firmware, you can just use What that does is:
uflash, tested on Ubuntu 22.04:git clone https://github.com/bbcmicrobit/micropython
cd micropython
git checkout 7fc33d13b31a915cbe90dc5d515c6337b5fa1660
uflash examples/led_dance.py- convert the MicroPython code to bytecode
- join it up with a prebuilt firmware that ships with uflash which contains the MicroPython interpreter
- flashes that
To build your own firmware see: Compile MicroPython code for Micro Bit locally on Ubuntu 22.04 with your own firmware

x86 Paging Tutorial Linux source tree Updated 2025-07-16
In
v4.2, look under arch/x86/:include/asm/pgtable*include/asm/page*mm/pgtable*mm/page*
There seems to be no structs defined to represent the pages, only macros:
include/asm/page_types.h is specially interesting. Excerpt:#define _PAGE_BIT_PRESENT 0 /* is present */
#define _PAGE_BIT_RW 1 /* writeable */
#define _PAGE_BIT_USER 2 /* userspace addressable */
#define _PAGE_BIT_PWT 3 /* page write through */ Complete metric space Updated 2025-07-16
In plain English: the space has no visible holes. If you start walking less and less on each step, you always converge to something that also falls in the space.
One notable example where completeness matters: Lebesgue integral of is complete but Riemann isn't.

Causality in quantum mechanics Updated 2025-07-16
In simple terms, if you believe in the Schrödinger equation and its modern probabilistic interpretation as described in the Schrödinger picture, then at first it seem that there is no strict causality to the outcome of experiments.
People have then tried to recover that by assuming that there is some inner sate beyond the Schrödinger equation, but these ideas are refuted by Bell test experiments, unless we give up the principle of locality, which feels more important, especially in special relativity, where faster-than-light implies time travel, which breaks causality even more dramatically.
