1. Why did the Polish power grab backfire?

2. Why did Spotify dampen the loudness of its music?

3. University of Vermont medical school really is moving to zero lectures.  They claim a ten percent retention rate for the material in the lectures, and that is for a quite elite group of students.  What is the rate elsewhere?

4. Arnold Kling on the “safe asset shortage.”

5. Could 3000 Jedi beat 60,000 medieval foot soldiers?  A simulation.

#3 – Uni with 0 lectures: eliminating the “sage on a stage”. Good idea, because not all sages are good lecturers. Also I hate it in uni where the professor says “you’ll be tested for the obscure points I make during lectures, so pay attention” – making class participation mandatory and the only thing being ‘tested’ (this is one reason I flunked out of law school; I was not learning the law, but obscure points of law that were contrived for testing purposes, to give a bell-shaped curve)

I’d rather see repeal and replace because I — I can do either way. If you remember, it was — you know, it was an idea that I had very early on, repeal. Trouble with repeal is you’ll have millions of people out there that — well, it’s like we just got the highest confidence in many years; you know, people out there that will say, well, you know, how do we know we’re going to have health care? And I hate to do that to people.

Lectures are a horrible way to convey information; I’m sure even the 10% was stuff they knew before class. For book knowledge, they can just read the textbook and be tested at the end. All of the rest involves treating actual pages. So basically medical school imparts no value just like regular school imparts no value, although in medical school only the patients get tortured.

Old joke (possibly true, possibly possible):

A student goes to the first meeting of a class. His professor says “Any questions? No? Ok, class dismissed.” The same thing happens the next week. The third week the professor says “No? You guys have a midterm coming up. If I were you, I’d ask some questions.”

And that was before flipped classrooms, etc.

Thirty-odd years ago, Marva Collins offered this explanation for the popularity of ‘look-say’ methods of reading instruction: teachers found teaching phonics to be repetitive and boring. “Easier for them” and “more pleasant for them” is, one might wager, the reason for all pedagogic innovations.

yup, anything an academic lecturer/teacher says during a routine session… can be written down or recorded… for infinite use by students. 95% of student questions can be anticipated & answered by competent textbooks.

“As anyone who has fallen asleep during a three-hour lecture class can attest, taking notes from “a sage on a stage” isn’t as effective as other ways to absorb information, and research confirms this. The main reason for the traditional method seems to be, well, tradition; medical professors and other teachers have been doing it this way for centuries.”

#5 Yeah, I’m going to say so because it’s not just the weapons, it’s the telekinetic force project they have as well. Not only do you have a weapon that cuts through everything but the ability to heave heavy objects but people also and stop them in their tracks. Properly coordinated with other Jedi’s you could effectively carve apart enemy forces into smaller portions and destroy them piecemeal.

Btw Thiago is right though about his previous comment, they’d have a hard time holding territory. Occupation is 99.9% shear boredom while you wait for something (usually very sudden and violent) to happen. Jedi’s would make horrible cops.

In the simulation they were medieval swordsmen with no ranged weapons. It’s doubtful if the Jedi would have survived if it was 50 archers or roman javelin throwers.

How accurately are these javelins being thrown? The Jedi doesn’t have to stop all of them, just the ones that are on target.

Also, I’m not convinced that the simulation properly accounted for formation. The soldiers were just a mob that ran at the Jedi. I think a more effective tactic would be to shield rush them. Don’t wave your sword at him with your shield hanging loose at your side. Charge in formation with shields up and knock him down. Drop the sword and stab with a dagger if you get him down. If the Jedi can force push them all away then he wins, otherwise he gets knifed.

#5 This looks like the same engine that had 10,000 chickens killing 10 T-rexes. Nothing I’ve seen of this simulation tool suggests that it adds significant insight. It just looks like it just has masses of units moving towards each other, with units only differing in different hit-points, damage, attack speed & maybe attack range. It’s not even clear that units are capable of hitting more than one enemy at a time.

But these types of scenarios are fun to think about, even if the technology to test them out isn’t there yet. In any full scale battle there would be a pretty immediate rout once it became clear that there was a near invincible enemy advancing on the field. But before that, the numerically superior army would try to surround and use ranged weapons against them.

3. Why is the lecture method for teaching the predominate method, especially at the elite colleges? People learn by listening, seeing, and doing. Which works best depends. Boys, being boys, learn very little by listening, a little bit by seeing, and mostly by doing. Girls, being girls, learn very little by doing, a little bit by seeing, and mostly by listening. Girls are verbal, boys are not. Yet, the lecture method persists. Why? Because people are lazy. What people? College professors. Reading a lecture to a college class is far easier than engaging the class in a discussion. Socrates knew how to engage his students: it’s even called the “Socratic method”. Socrates is dead, while the lecture lives on.

#1 “power grab” – ha ha ha. Yeah. Legislatively enacted judicial reform is “a power grab.” I suppose Bezos’s barmy minions don’t realize that the Poles are a people of honor and integrity, unlike the grubby bootlickers in the US who submit to a “living constitution” which happens to mean whatever is politically expedient for the Democrats at the moment. The Poles could have used their intelligence services to gather dirt on the equivalent of their chief justice and forced him to say black is white, a fine is a tax, and it is perfectly constitutional for major industries to pay off the legislature to mandate that citizens buy their products. They could have gotten money from a Soros-equivalent and bought a bunch of officials positions as prosecutors and judges, but no, the Poles do things transparently and honestly. And that apparently is a major crime in the yes of the exalted elites of the US who prefer to maintain their wretched little establishment via corruption and fraud and can’t stand to be reminded of how vile and reprehensible their reign will be regarded in the annals of history.

More on the theme:

“These bizarre lies are not merely a symptom of Trump’s idiosyncratic verbal diarrhea. They grow out of a long tradition of paranoia that once lurked on the margins of American politics. Paranoid thinking can be found on both the far right and the far left. But while left-wing paranoia remains mostly confined to the margins — Jill Stein’s candidacy acted as a magnet for the left-wing sort — the right-wing variety has made deep inroads into Republican politics.”

I dunno – I can’t say I understand the sides, but the direction seems clear enough. It’s like the Gulenists in Turkey – plenty there to criticize, but, as events unfolded, they weren’t the ones putting a bullet through democracy. I suppose it could be closer to Egypt, where the Muslim Brotherhood had legitimacy, but seemed just as drawn to single-party rule as the military junta. From what I can see, Poland looks closer to Turkey. F’in depressing times for those who want to believe that democracy is the best governing system humans have come up with.

“By reducing the LUFS index, Spotify is telling the music industry that there’s no use in trying to sound louder than everyone else.”

In effect Spotify is penalizing songs recorded with more compression, as these will now sound uniformly mid-volume after Spotify is done with them, while those with less compression will stand out by having higher maximum loudness.

But that means Spotify will not sound as loud as other streaming services.

And, yes, extreme compression is annoying, but the music industry has been doing it for years now and the fans haven’t pushed back by refusing these “everything louder than everything else” recordings.

So, my prediction is that Spotify will soon turn its volume back up to “11” (and thereafter will never, ever consider turning it back down).

True. The largest city in Vermont has about 90,000 people in it, far too small for a university medical center. About 85% of the population of northern New England is exurban, small town, and rural. The adjacent portion of New York has about 650,000 people and no population centers with more than 40,000 people. Research universities planted in places like Maine and Vermont are problematic. Ideally, they’d stick to state colleges and have interstate-compacts with the other New England states which would allow their residents to attend graduate and professional programs in Boston, Providence, Hartford &c for in-state tuition.

They swing their laser swords like heavy baseball bats even though they can cut through anything instantly. A good fencer could thrust, deliver a fatal blow, and recover in the time it takes a Jedi to do his ridiculous baseball swing.
