But what can you do with it? Radio contact with the moon?
soldeace · 5 months ago
Despite being theoretically possible, much of the signal directed at the Moon would be absorbed in the upper atmosphere at this wavelength. On the other hand, the 10-40m bands are fantastic for long-range "earthly" communication (when the conditions are proper).

I used that website everyday when I was prepping for my ham license upgrade and got reasonably good after a while, being 25 WPM my most comfortable speed. But then I learned that the CW exam in Brazil was carried out at 5 WPM. When I tried that speed, much to my surprise I couldn't understand a single word. I had to relearn slow Morse on lcwo.net from scratch weeks before the test. My takeaway was that our brains seem to get super specialized, so if you're studying for a CW exam yourself, I do recommend immersing yourself in CW at roughly the same speed as the exam.

At any rate, really cool website!

Only after I've got my ham radio license that I learned how these USB switches are annoying sources of RFI, even the more expensive ones. KVM switches are fine though.

For the best part of my life I use a controlled set of tags[1] rather than hierarchical categories. This is mostly due to the fact that stuff can be a lot of things at the same time.

That said, one of the best use cases for Johnny's system I've found is when you have to share an online drive with hundreds of people, where you can't use tags, and even if you could, there would be no consensus. Strangely, nowadays I can find my way around a huge project's online files quite easily just by the prefix numbers of each categorical level.

> Anyone who has ever used IRC knows that there is nothing even remotely complicated about using it, but the terminology and the steps required to use one are ostensibly terrifying enough to reliably keep the technically illiterate at bay.

This remark, topped with the author's piece on "normiefication", is the kind of intellectual elitism that reliably keeps me away from IRC whenever I think of coming back to it.

soldeace commented on Journalists should be skeptical of all sources including scientists   natesilver.substack.com/p... · Posted by u/amadeuspagel

Big question: HOW?

Most journalists in the USA receive basically zero scientific education. At university I majored in two STEM subjects but also took 10 courses in Philosophy, Art, History, Journalism, and Economics. Almost no one majoring in any of those fields except Econ took more than 2-3 STEM courses, and even then there a dedicated watered down courses to ensure those people could graduate (Algebra instead of Calculus, "Physics for Future Presidents", etc.).

My high school education in the humanities was also far better than my high school education in STEM, which is typical. And the deplorable state of Mathematics education in US high schools acts as a hard constraint toward improving the situation, since you need a baseline of mathematics literacy before proceeding along any other path in STEM.

How are journalists supposed to be productively skeptical when the vast majority of them don't receive anything remotely approaching a truly well-rounded education?

Go read the proximal origins paper. How is a journalist who has never seen a derivative, has never taken BIO 101, and whose Science distribution credit was fulfilled by Physics For Future Presidents supposed to dive into the claims in that paper and critically evaluate the surrounding literature? They can't.

At least for this particular case it was not a matter of teaching journalists statistics or anything STEM-related. If it weren't for the leaked messages, we'd never hear about it. Epistemic sincerity and a good notion of statistics are important for sure, but giving whistleblowers legal cover and a means of releasing this kind of material is just as important.

That is not how it works.

Coming from a Scandinavian country, we started learning English around the age of 8, and at the age of 15 my English was good enough that I was reading the Harry Potter books in English as they were published, rather than wait six months for the translation. Then I was also learning a third language from age 13 to 19.

And it's well documented that learning new languages, similar to playing sports or doing crafts or other stuff, is very beneficial for brain development in children and young adults.

If your hypothesis made sense, the United Kingdom should have a huge advantage over other European countries within science and other fields where English is predominantly used. But it does not. You can e.g. look at metrics like "number of scientific publications per capita", where the UK is only number 20 in the world, and the US is number 33.

I understand that learning English may have not been that hard for you, and given that you come from a Scandinavian country, most likely you speak near-perfect English (I've been to Norway once, it's amazing how even the old lady in the yarn store speaks English so fluently!) Also, no one is contesting the benefits of learning something new.

But keep in mind that different cultures face significantly different difficulties when it comes to pick up a foreign language. I'm based in Brazil and I can tell you with reasonable confidence: the average person in Latin America struggles A LOT to get past Harry Potter books and achieve full work proficiency. This can be due to significantly different grammatical structures, word roots, phonemes, and whatnot, or---most importantly---due to the fact that most of us can't afford quality language courses at affordable prices. In reality, good and affordable schools in our own native language is considered a privilege to many.

So either due to structural differences between languages (especially those that don't share the same Germanic roots as English), or due to economical and social issues, some non-English speakers have to spend hours of deliberate practice to be on the same ground as people from a few other countries, in academia or in a multi-cultural IT team. I myself can't count the number of hours of pronunciation practice I amassed throughout the years for being too afraid of sounding dumb in my daily scrums. This is something I'm pretty sure a native speaker doesn't have to mind with when starting at a new job.

That said, I don't see how the "UK vs. rest of Europe in numbers of papers" could support the claim that a head start doesn't exist. There are a number of infinitely more relevant variables that could explain scientific throughput by country.

I really like the typeface, but for some reason it looks "blurred" in comparison to all other mono fonts I have installed. Anyone noticed the same?

One of the most useful features on Twitter for me was the option to mute retweets. After doing this, my feed's signal-to-noise ratio skyrocketed.
