This section is about companies that integrate parts and software from various other companies to make up fully working computer systems.

The japanese name literally means:

This section is about the definition of the dot product over ${\mathbb{C}}^n$, which extends the definition of the dot product over ${\mathbb{R}}^n$.

Some motivation is discussed at: math.stackexchange.com/questions/2459814/what-is-the-dot-product-of-complex-vectors/4300169#4300169

The complex dot product is defined as:

E.g. in ${\mathbb{C}}^1$:

We can see therefore that this is a form, and a positive definite because:

Just like the usual dot product, this will be a positive definite symmetric bilinear form by definition.

Triangle, tetrahedron.

The name does not imply regular by default. For regular ones, you should say "regular polytope".

Non-regular description: take convex hull take D + 1 vertices that are not on a single D-plan.

Besides the understandable Wikipedia definition, Video "Simple Groups - Abstract Algebra by Socratica (2018)" gives an understandable one:

We don't really know how to make up larger groups from smaller simple groups, which would complete the classification of finite groups:

In particular, this is hard because you can't just take the direct product of groups to retrieve the original group: Section "Relationship between the quotient group and direct products".

Brand according to documents: SMEG.

Most similar models I an find: www.smeguk.com/products/UKC8173N1F and www.smeguk.com/products/UKC81721F, the keyword are "built-in" and "integrated", other very similar ones: www.smeguk.com/refrigerators/built-in

Looks like this: www.youtube.com/watch?v=4c_LBVnU4ec and that's how to unclog the drain.

2020-11-28: defrost. Some small Styrofoam was broken lose from top, noticed small burn or rust marks on top grid nearby.

~1TB.

Internal hard drive likely removed from some old computer I lost track of, kept in a crappy case, incredible stuff.

Ubuntu 20.04 gnome-disks benchmark, NTFS partition: 40MB/s.

Black EUR 44, 1 smaller than normal size as recommended by website.

Bought SM-SH56 cleat to accompany.

When it arrived, it felt a bit too long, around 2cm maybe free space after toe, and when I walk and the front part touches ground, heel comes off a bit, which is annoying. But I was too lazy to give it back and take the risk of a second try, also it felt correctly tight on sides. During first test ride it felt good.

It is slightly water proof. But if it rains a lot, it will get soaking wet. And once it does get wet, it feels like it is very very hard to dry, there don't seem to be any holes underneath.
