It ain't perfect, but it's decent enough.

From a technical point of view, it can do anything that Microsoft Windows can. Except being forcefully installed on every non-MacOS 2019 computer you can buy.

Ciro Santilli's conversion to Linux happened around 2012, and was a central part of Ciro Santilli's Open Source Enlightenment, since it fundamentally enables the discovery and contribution to open source software. Because what awesome open source person would waste time porting their amazing projects to closed source OSes?

Ciro's modest nature can be seen as he likes to compare this event Buddha's Great Renunciation.

Linux should track glibc and POSIX command line utilities in-tree like BSD Operating System, otherwise people have no way to get the thing running in the first place without blobs or large out-of-tree scripts! Another enlightened soul who agrees.

Particularly interesting in the history of Linux is how it won out over the open competitors that were coming up in the time: MINIX (see the chat) and BSD Operating System that got legally bogged down at the critical growth moment.

You must watch this: truth Happens advertisement by Red Hat.

899 USD as of 2022, takes a year to ship as they gather up a lot of orders before producing.

Sounds so cool, especially the multi functionality. Shame so expensive.

How to decide if an ORM is decent? Just try to replicate every SQL query from nodejs/sequelize/raw/many_to_many.js on PostgreSQL and SQLite.

There is only a very finite number of possible reasonable queries on a two table many to many relationship with a join table. A decent ORM has to be able to do them all.

If it can do all those queries, then the ORM can actually do a good subset of SQL and is decent. If not, it can't, and this will make you suffer. E.g. Sequelize v5 is such an ORM that makes you suffer.

The next thing to check are transactions.

Basically, all of those come up if you try to implement a blog hello world world such as gothinkster/realworld correctly, i.e. without unnecessary inefficiencies due to your ORM on top of underlying SQL, and dealing with concurrency.

Ciro Santilli's jaw dropped when he learned about this concept. A Small Talent for War, are you sure?

Some of the most notable ones:

One of the Millennium Prize Problems.

See also: existence and uniqueness of solutions of partial differential equations.

The cause of variable number tandem repeat.

These can be used to break cells apart from tissue, and also break up larger DNA or RNA molecules into smallers ones, suitable for sequencing.

One of the brightest natural objects in the sky, and by far the brightest not in the Milky Way! This is partly because it is relatively close to us.

Many devborads require a 5V power supply.

This is common on wall transformers and USB, but not in batteries.

For battery power you need a transformer.

An artificial metabolic pathway using synthetic biology technology.

This is a well known though experiment, which Richard Feynman used to emphasize

In the above experiment:

The solution to this problem is length contraction: the positive charges are length contracted and the moving electrons aren't, and therefore they are denser and therefore there is an effective charge from that frame.

This is also mentioned at David Tong www.damtp.cam.ac.uk/user/tong/em/el4.pdf (archive) "David Tong: Lectures on Electromagnetism - 5. Electromagnetism and Relativity" "5.2.1 Magnetism and Relativity".

Ciro Santilli was contributing to this, when CommonMark left private mode and killed it, thus wasting many hours of Ciro's time.

OK, so let's verify the main desired consequence of the Lorentz transformation: that everyone observes the same speed of light.

Observers will measure the speed of light by calculating how long it takes the light going towards $+x$ cross a rod of length $L=x_2-x_1$ laid in the x axis at position $X1$.

TODO image.

Each observer will observe two events:

Supposing that the standing observer measures the speed of light as $c$ and that light hits the left side of the rod at time $T1$, then he observes the coordinates:

Now, if we transform for the moving observer:and so the moving observer measures the speed of light as:
