This is mostly stuff from before 2016 when Ciro was anxious to document his contributions to get a job.

Most of the projects here are also minor contributions, or Ciro later noticed that the projects were not useful enough to work on and that he was actually wasting his time.

Some of the contributions are subjectively self evaluated based on:

Only patches which were reviewed by at least one person with push permission will be listed here.

This may also include patches which were rejected in favor of another patch, but strongly influenced the merged patch.

Patches which were merged by Ciro himself on repositories which eh feels have large public visibility, e.g. those to which he has been given push permission.

Repositories to which Ciro gained push permission because of his contributions:

This shall not list bugs solved by my accepted pull requests.

Disclaimer: closed source vendors tend to be highly secretive, solving small issues without any reply, so I use my best judgement given the lack of feedback.

The following contributions where not immediately verified by others, but they were not reverted either and I think they are good.

This section contains the a list of cool things Ciro Santilli has been up to in chronological order, including small quick ones. Many/most of those are also posted on Ciro Santilli's accounts such as:

This is meant to be an answer to: diy.stackexchange.com/questions/27669/how-can-i-thoroughly-blackout-a-bedroom-window-on-a-budget but that question was protected and I can't answer right now because I don't have 10 reputation on the website, so here goes.

This is my first working setup, done in a rental friendly way without drilling. I am sure that it is possible to do it cheaper, better and with less work, but it the first one that worked for me, so I will document it.

Cost: 150 Dollars for a relatively large 130 x 158 cm window. They do not sell for windows much larger than that.

Bought from www.orderblinds.co.uk on June 2019.

My window faces East, and in summer the sun rises at around 5AM here, and I am a bit light sensitive and was getting destroyed.

This setup, together with:is good enough to allow me to sleep properly, which is priceless.

Demonstration if everything goes exceptionally well:

However, not all will necessarily be fun and games as in that YouTube video, especially if you are doing it for the first time, and the main point of this article is to make you aware of that.

The first problem is that you may have to remove existing useless "privacy blinds" from the way, which can mean putting effort into learning how they work and, has a risk of damaging the property. So be smart and get a chair and a second person to help you out!

Next, fitting the side rails is not going to be that easy. The thing has to be tight to block the light, right? Careful not to scratch the bottom sill!

Then you will notice that, like in the video at youtu.be/cTVVe7codw4?t=106, you are expected to screw the side rails to the bottom wood / plastic sill of the window, which is not rental acceptable! So I didn't to that, but together with the black tape that I will mention next, it held well enough.

The top part requires hammering nails as shown on the video: youtu.be/cTVVe7codw4?t=24 but this is generally rental acceptable, and you can fill the holes afterwards.

Once you have the setup in place, it is likely that there will be some light gaps still, because it is basically impossible to make such large objects fit perfectly. This was especially true for the top of the window, but also for the sides, so I just used some black tape

So I added some wide (50mm) Figure 4. "Diall PVC repairing black tape" between the blind and the wall to completely seal off the light.

There is still some leakage at the bottom however, which cannot be taped. I mitigated that a bit by putting some black T-shirts on the bottom window sill, and together with the pre-existing rental curtain, it was enough.

Another minor annoyance is that parts of the blind cloth sometimes slip out of the conduit holes in the aluminium side bars. For this reason, I have to always open and close slowly and carefully. But if it does happen, fully opening and closing carefully has solved the problem.

After removing it:

Of course, we already knew that minimal plaster work would be needed from the start, since we have to hammer two small nails into the wall. But that level of damage might have been easily dealt with by a non-professional tenant himself. But the level I had was a bit more than I felt I should handle myself.

The problem with virtually all sleeping masks on the market is that they leave a lot of room near your nose for light to come in.

Ciro Santilli discovered a useful workaround for that: make the mask tighter with a swimming goggles!

Just make the goggles as loose as possible to not put pressure on your eyes, and then strap them over the sleeping mask.

If you are a back sleeper, put the googles forward as normal. If you are a stomach sleeper, put the googles on the back of your head, and the straps over the mask. This way you wont get your head squished by the goggles and the bed.

Once Ciro understood the idea, Googling "swimming googles sleeping mask" led to: mantasleep.uk/ might be a good option.

Another good Google is "sleeping mask blackout".

Looking at the energy level of the Schrödinger equation solution for the hydrogen atom, you would guess that for multi-electron atoms that only the principal quantum number would matter, azimuthal quantum number getting filled randomly.

However, orbitals energies for large atoms don't increase in energy like those of hydrogen due to electron-electron interactions.

In particular, the following would not be naively expected:

This rule is only an approximation, there exist exceptions to the Madelung energy ordering rule.

This is the most important of all points.

Don't set goals for your students.

Ask students what they want to do, and help them achieve that goal.

If they don't know what to do, give suggestions of interesting things they could do.

Once they have a goal, just help them learn everything that is needed to achieve that goal

If they don't have a goal, any attempt to learn is a total and complete waste of time.

This is because the universe of potentially useful things that can be learnt is infinite, and no human can ever learn everything.

The only solution, is to try and learn only what seems necessary to reach your goal, and just try to reach your goal instead.

This approach is called backward design.

Also, setting overly ambitious goals, is a good idea: the side effects of ambitious goals are often the most valuable thing achieved.

"Graduating" and "getting a diploma" are not valid goals, because they are useless. A goal has to be either an amazing specific technological or artistic development.

Grouping by age as done in traditional education as of 2020 is useless.

Rather, we should group students by subject of interest; e.g. natural sciences, social sciences, a sport, etc., just like in any working adult organization!

This way, younger students can actually actively learn from and collaborate with older students about, see notably Jacques Monod's you can learn more from older students than from faculty.

This becomes even more natural when you try to give students must have a flexible choice of what to learn.

This age distinction should be abolished at all stages of the system, not only within K-12, but also across K-12, undergraduate education and postgraduate education.

This idea is part of the ideal that the learning environment should be more like a dojo environment (AKA peer tutoring, see also dojo learning model), rather than an amorphous checkbox ticking exercise in bureaucracy so that "everyone is educated".

Perhaps, even more importantly, is that we should put much more emphasis on grouping students with other students online, where we can select similar interest amongst the entire population and not just on a per-local-neighbourhood basis.
