People may not trust systemd because years ago there were some really bad defaults like https://github.com/systemd/systemd/issues/2402 that for instance mounted your firmware in read write mode by default.
That kind of thing leaves a bad taste in some peoples mouth. I am pretty sure some people have bricked hardware with systemd.
Or when they started killing user background processes (screen/tmux/nohup X) instead of sending SIGUP like POSIX/Unix has done since basically forever:
As someone who runs mostly servers, I also find resolved annoying and have to rip it out. There's also all sorts of tomfoolery with /etc/resolv.conf in many modern distros, to the point I've taken to setting the immutable flag on it to prevent things diddling with it.
There was also the bug where systemD wouldn't allow usernames that started with a number. Poettering's (initial?) response was to tag it as "not-a-bug":
> Yes, as you found out "0day" is not a valid username. I wonder which tool permitted you to create it in the first place. Note that not permitting numeric first characters is done on purpose: to avoid ambiguities between numeric UID and textual user names.
Where is your data? Is it in the CPU cache or is it in the GPU? Computing where your data is, rather than moving your data to where your compute is, can often be the best option.
For small networks it's often a win to stay on chip at least on the power side. But if you do need to go off chip for memory it's hard to beat the memory bandwidth you have on a GPU.
I do have a bit of physics in my background. I read about Grassmann recently in a game programming book. Foundations of game engine development Volume 1 By Eric Lengyel ends with a nice explanation of Grassmann algebra.
The road to reality by Roger Penrose also has a treatment of Grassmann algebra in physics context.
I agree the library is likely a reference to the mathematician.
Interesting. Yeah it's nothing too important it's just that I've only ever seen physicists use Grassman numbers, whereas mathematicians tend to work with the exterior algebra directly (which works in much the same way except the wedge operator is used explicitly, IMHO this makes things clearer).
Sure, but the Grassman numbers are a bit of an odd model of Grassman algebra with its own notation. They live in some anonymous vector space that is effectively defined in terms of the Grassman numbers, whereas mathematicians usually have some vector space they're interested in and construct an exterior algebra from its elements. The differences are minor but they're two clearly distinct approaches.
Like I said it's nothing terribly important but it's still an interesting difference.
I agree, the subtle difference between the physics and math mindset is interesting. I wound up on the sidelines as a computer scientist who worked in a physics lab.
