"In 2023, it became the first metro system in the world to operate entirely on electric power."
That is very confusing. Most of the article seems to be about metro systems (a.k.a. underground, subway, the tubes, etc.). What happened in Oslo in 2023 is they electrified their bus lines (i.e. surface transport). I think most actual metro (sub surface) system have been entirely electric for quite a while.
I remember in the summer of 89 having to wait several hours in Uzhhorod for exactly this reason. I don't remember if they kicked us of the train or if we wanted to use the opportunity to do some sightseeing, but there were no sights to see in Uzhhorod in 1989. The most notable thing we found was a local "wall of shame": a display case with pictures of local miscreants, together with the listings of their crimes. Being at the height of Gorbachev's prohibition, the most common crime was "drinking alcoholic beverages in public". I think that if I had to live in Uzhhorod in late 1980's, I would probably end up drinking alcoholic beverages in public as well.
First, I never liked Gnome, I remember trying it few times years ago, and quickly returning back to fvwm2 every time. On the other hand, I never understood why window managers put icons on the window title bars, and in my own fvwm2 config, the max and min icons were the first thing I removed. I mostly used keyboard to toggle between maximized and unmaximized state of a window, and if I really needed a mouse for it, I would double click the title bar with the same effect (I also used keyboard to toggle vertical only and horizontal only maximization). With practically unlimited number of virtual desktops, I never needed to minimize a window, and I usually had too many windows open for a taskbar to be useful, instead I had a popup menu for finding windows (both just this desktop and all desktops). Now, after switching to i3, my windows still have no icons on title bars, and I use rofi to find windows, so still no taskbar.
Olympics are a great point of national pride for the organizing country. I don't understand why these days we still let each Olympics be organized by a single country. It could very easily become a global event, where different disciplines would happen in different parts of the world.
More importantly, though, Olympics have become a major capitalism fest, its increasingly about consumption, and a small number of already very rich people making shitload of money at the expense of the public in the organizing country.
I believe you've got it backwards. The theory of relativity would be wrong if GPS did not work, the theory of electromagnetism would be wrong if radio did not work, etc. The only thing that working radio tells us is that certain mathematical model that we call theory of electromagnetism happens to agree with the real world (whatever that is) to a sufficient precision. For many purposes (like for example building radios), that is enough.
Writing novels and analyzing novels are completely orthogonal skills. I bet there are many great authors who would completely suck at explaining other authors' works (or even their own), comparing different works, or explaining how literary works fit into and interact with the rest of the culture.
> What if the standardized tests aren't administered by the teacher? That seems like it would be an easy solution to get around the cheating problem.
In order for the test scores to be granular enough to be used as measure of performance of individual teachers, the testing would have to be done fairly often. The schools and school districts that are already lacking funds for basic stuff like maintenance and teacher and staff salaries would have hard time to pay an additional subject to administer the test.
With the frequency and volume of testing, it would likely be too costly to do the testing in an external testing facility (which most districts do not have), so it would have to be done on site. I remember my kids telling me that every time before they took a standardized test (it happens once a year around here), the teachers told them basically "we cannot give you the answers, but look around, the answers may already be there, there may be a poster hanging on the wall or something else like that that may be helpful."
Years ago I used one of the first pis as a music/podcast player in my car. The problem was that there was no proper shutdown process, you turn of the car, and the power cuts off, so I set it up to create and mount a ram disk while booting, and do all writing to the ram disk. From the comments here, it looks like the newer pis have this as a config option now.
A mandatory nitpick: you cannot do conditional probability without multivariate distributions, but you are right, you do not need linear algebra for a basic introduction. Even continuous distribution can be introduced, you just start with discrete cases, introduce areas in a histogram, and then approximate the histogram by a continuous curve. You can even get to the Riemann integral that way if you want to. And nobody actually calculates normal probabilities by integrating the Gaussian function, it's kind of hard to do.
> so much like high school physics will not teach thinking but simply knowing how to apply the right formula at the right time...
Unfortunately, that seems to apply to a lot of high school math, including a lot of calculus classes. And, to shoot into my own ranks, college math and especially statistics classes are far from immune to this as well.
Chain rule is a bad example. If you cannot remember the chain rule, you do not understand the theory at all. And if you do understand what a derivative is, the chain rule is trivial.
> And these people upload the content that we all enjoy watching.
Maybe you should speak only for yourself. It is possible that most people uploading to youtube do it because of the adds, but there are plenty of people who have other reasons. Most people I watch regularly do not even have enough views to get any add revenue. There are plenty of us who prefer contents that was not created with adds in mind.
I really do not understand what the complain about IBM is about. Are they saying that if you request a source code from IBM, they will stop developing Red Hat and there will be no future releases? Or are they saying that if you request the source code, you will be blacklisted by IBM from buying any future versions or upgrades? I am no fan of IBM, but it seems to me that what they are doing is completely withing not just the letter, but also the spirit of the GPL.
