> it's hardest to get started when the concepts are new and foreign and easier later when your just adding a deep understanding to what you have already fought to learn.

This is quite true; I feel this is the case with maths. Simple math, logic math is all fine, but higher maths and theorems I find very, very difficult to understand. Here this is one of the few areas where my memorizing techniques did not work well. Sure I can remember many things, but applying that knowledge is very different to just memorizing stuff.

He makes some good points. Anki is indeed popular, so this is true too.

I am using my own set of flashcards via self-written computer programs, mostly small scripts. The core is simple: one "side" has the question, the other "side" has the answer. I enhanced this on the commandline though, e. g. I can refer to local images (we can show this on the terminal, e. g. I use KDE konsole and then some different commandline programs to show things there. I can even show individual slides of .pdf pages via https://github.com/hzeller/timg, which is pretty cool since I can control which pdf file to show, sometimes manipulating them before showing that).

The author of that blog post at lesleylai, though, is wrong in some regards.

For instance:

> don’t memorize what you don’t understand

I totally understand what he means, e. g. "understand it first before memorizing", and while this is in some ways true, in other ways it is not. I literally had to memorize crap knowledge in order to pass some exams. Some of it was simply boring to no ends, other things were too complicated, but in BOTH cases, being able to memorize it, helped. I may not always understand everything, but being able to connect at the least some parts, did help, just like a spider web that is built up slowly. With that I could lateron learn more, connect more and so forth.

So, while I do agree that understanding is better, sometimes you can not, perhaps you lack time. Even in ALL these cases I had over the years, it still was better to be able to memorize even trivial facts. Of course eventually you have to be picky as to what knowledge you want to store in the brain, since I think it can not store infinite knowledge really (just about everyone forgets stuff eventually), but if your goal is to e. g. pass some exams quickly, then being able to quickly memorize even trivial crap, can be useful. There are a few other things I disagree with too, but for the most part I think this is a very useful blog entry. I am curious what people use else, e. g. other than anki and so forth. Or they may have other learning tricks. I always try to re-align my knowledge when it is for an important topic I care about; topics I once learned but never need again I kind of put into a "storage" preservation mode, e. g. if I ever need it again, I can look it up, but other than that I focus on what seems to be more important to me.

Agreed - I'd consider this public pollution caused by extremely greedy billionaires ruining the planet. They could only amass money because they did not care about social responsibilities prior to do so; any contrary statement made by them to this is only lies, lies and more lies.

Unfortunately you need a government that cares for the whole; in the USA oligarchs rule, so the general public are treated as paying slaves.

> After getting comfortable reading code with so many parentheses

I never managed to get over the ().

Ruby has a very flexible syntax, compared to many other languages, in that you can omit syntax in many cases. For instance, using () for method calls is largely, for the most part, optional. So when I have the python code:

    cat = Cat()
    cat.meow()
I find it worse than the ruby code:

    cat = Cat.new
    cat.meow
(Though you can use () in ruby there too; but most people won't do so as there is little point in that.)

This is a superficial issue though. Python's biggest mistake is to require implicit self. It always feels as if I need to hand-hold python and trying to explain to it what an object is and what self is. In ruby I don't have that issue. Note that I find both languages fine, but ruby is "more" object oriented than python is, for many reasons.

Lisp is quite different though. I had some exposure to it via scheme and while it can be fun, I feel that lisp is a worse programming language than either ruby or python. The old game haxima/nazghul was given up eventually, primarily due to lack of time, but also because the author was no longer convinced of scheme (the core of the engine is in C if I recall correctly). He tried to switch to python, though, which did not work (but, again, I think it was mostly due to lack of time). The scheme code in haxima/nazghul was quite interesting (https://sourceforge.net/projects/nazghul/ if you want to look at the scheme code there), but I much prefer either ruby or python there. Although it would be interesting to have DSLs that would really focus on the game or project at hand, like in the old Zak McKracken game.

That's actually interesting - gives C developers motivation to improve postgresql. after all people could say "look, Rust makes this easier".

> I'm really surprised at the hurry.

Well, once you realise that the so-called "EU parliament" is nothing but a lobbyist group (see https://en.wikipedia.org/wiki/Qatar_corruption_scandal_at_th...) it is no longer surprising. To me nothing here is surprising, neither the hurry nor any slowness.

Lobbyists are winning the war.

I can not evaluate the claims made, but even if I am lenient and assume it is all true, to me it is still strange how a distribution becomes so dependent on a single person or provider. I can't help but wonder how other distributions would have handled that; Gentoo would probably not have ended in a similar situation, debian probably neither.

And mind you - that's only if I evaluate the claims made at face value. I also can't help but feel that there are some missing steps here. Sure, IRC roid-raging happened in the past, see #freenode, and people are strange in general, but even then it really reads oddly to me, almost as if "I trusted that scammer from Nigeria with my money because the emails were so convincing".

This assumes the mites are what kills the bees. What is that asssumption is flawed?
shevy-java
·一昨日·議論
No. The mites are not what is killing the bees.

And, by the way - natural pathogens exist in just about any population. These very, very rarely led to extinction. There is a media trend to claim the mites are at fault. This reminds me of prior fault yielding e. g. "mad cow disease" - and then the media also stopped doing any further investigation at that point. It's as if they have break points where you can not go past those points. Now it is the mites that get blamed.

Still the honeybees keep on dying ...

Perhaps it is time to stop blaming the mites for the decline of the honeybees.

Voting on hackernews is a bit weird compared to reddit. The whole UI is strange to me.

Having said that, I noticed that there is in general too much content to consistently e. g. vote or do similar actions. I was watching Rossman's video almost daily in the past; stopped doing so a while ago simply because of lack of time on my part. I need to choose more carefully where I invest my time. (Also, for some reason, when Rossman was in New York, his videos had a better punch; not sure if I am the only one noticing this but he seemed to have a better focus when he was still in New York, even though I understand he relocated, to stop getting milked by politicians in New York.)

Good. However had, one question still remains: why did the US government not have this automatically put in place in general? The title refers to one company for the most part. The question is why the US government, which assumingly should work for the people, prioritizes private commercial interests over individual ownership models.

This is a bit skewed. AfD stands for a lot more than "merely" an opponent of chat control, including worshipping the 1930s era.

As another example, one of their members (Noah Krieger) fights on behalf of Russia, conquering lands and killing civilians (article from today only in german, sorry: https://www.tagesspiegel.de/politik/videos-mit-schutzweste-u...). And many other problems I could list about AfD. So t he "they want to ban those opposing chat control" - sorry, that is a huge simplification.

> It would be hard to imagine a US party that didn't believe the other party is out of compliance with US values.

Ah? And why are there only two corrupt parties in the USA to begin with? I mean that's no real choice. Both are corrupt, and one now entered cult-status with the mad orange king. His cronies get rich. Everyone sees this. So, sorry, but your attempt to promote the USA while praising the AfD, is simply flat out rubbish nonsense. We only have bad actors here, no good ones.
