There was a 1D Wolfenstein that was entirely played in the url bar, and yet made perfect sense and was quite playable.

“Repeatable identifiable categories of dubious usefulness”

Yep, there’s a lot of this in modern science.

“Is this method of classification useful? wrong question! All you need to ask is, is it easy to write a reproducible paper (or shareable web content) on this method of classification? Yes, yes it is!”

There’s a lamppost problem at work here.

> I’ve been learning guitar over the past couple of years and I still struggle with many aspects (with good rhythm and timing being the most difficult).

Same, same and same, here.

Good luck to you!

The book “Peak” - and other works by that author detail studies related to this.

> The book was written partly as a response to the misrepresented but increasingly commonplace idea of the "10,000-hour rule," popularized by Malcolm Gladwell in his 2008 book Outliers and which Gladwell had based on Ericsson's own research.

Here is a different video by the same person (the `robWords` channel)

“How to translate French words WITHOUT KNOWING FRENCH (3 clever tricks)”

I learned a lot from this and continue to find words that these lessons apply to.

I think it’s the other way around — the book is from ~ 1985 while the Roger Waters albums is ~ 1992.
LeonB··on DOJ claims Google has "trifecta of monopolies" on Day 1 of ad tech trial
> (theoretically at least)

The “at least” is unwarranted, and even the “theoretically” is being far too kind.

Of course if you allow a monopoly to develop they will protect their own interests to the exclusion of others, and use their power to entrench their position. Even the oldest theories about markets point out the dangers of monopolies.

> being able to buy 0.001% of a billboard

^^ this is possible because the ads are delivered digitally, not because of any magic power google has.

Even if every website was its own independent advertising space (an extreme opposite), they could all still be open to advertising companies big and small by using “open standards”.

The innovations are all technological.

LeonB··on Against Rereading
Well, Sylvester (see footnote), or Euclid, whatever your name is, I think you get what I’m saying.

Footnote: on rereading your message, the sequence 2,3,7,43,1807 jumped out at me as being “Sylvester’s sequence” — sometimes called Euclid numbers — I definitely did not have to look that up in the online integer sequence database and simply know all these things intuitively.

LeonB··on Against Rereading
I read your comment and thought, “that’s quite a simplistic thing to say, hardly worth making such a comment.”

But I re-read it and thought, “then again the commenter is saying ‘good’ not ‘great’… perhaps they are admitting to more nuance?”

Interesting concepts, thank you.

LeonB··on Hallelujah, Leonard Cohen, and a Pulitzer Prize-winning writer's suicide
I didn’t want to comment until I’d seen the video — I’ve seen it now and I think it’s really interesting, and brings in a lot of relevant points.

Personally, I would be quite adamant that the reason the word “chord” is chosen there — is for a much simpler reason: it rhymes perfectly with “Lord”. (At first I wrote, a more “prosaic reason” — then realised that while it is a simple reason it is the opposite of “prosaic” - it is literally “poetic”).

But the nature of this video — searching for meaning within a work of art - I think this is a great way to engage with art, and a special kind of joy all its own. Such interpretations are meaningful and can be “true” regardless of whether the author literally meant it the way you take it.

If a physics paper interpreted results of an experiment in this way, or if a jury interpreted evidence in this way, I don’t think it would be good science or justice, as the case may be. But for enjoying and experiencing art in a “meaningful” way, this kind of approach is well worth it.

LeonB··on Kids who use ChatGPT as a study assistant do worse on tests
Good point about disproving your answer (before seeing the alleged real answer). The ability to quickly verify/disprove the answer is a separate and useful skill all by itself, that isn’t explicitly taught.

Troubleshooting/problem solving, working backwards from symptom to problem etc — that’s another, richer and very rewarding “real world” type of skill that isn’t directly taught, (though often encountered incidentally).

Same! I couldn’t get it to work because that sailboat was in the way.
LeonB··on A Real Life Off-by-One Error
Once an activity has become a “competitive sport” it has a way of prioritising “measurable” over meaningful or enjoyable. When you develop a critical eye for this aspect of sport, the Olympics stop being enjoyable and become an utter horror of human maladjustment, a horrid parody of what it alleges to stand for.

Most people don’t get any choice at all about what operating system they use. And those that do get a choice have extremely limited options.

I think the song TUSA, in which Ginger Baker describes the process of making Tea is also a required reference for any articles on the topic.

LeonB··on Deliberate Practice and Acquisition of Expert Performance: A General Overview
I think this is a confusion between “marginal” and “by and large”.

If I go to a coach to help me with running faster their advice won’t be “completely wrong” — it will be “by and large” correct.

But there are still opportunities for “marginal” improvements that can be found with better measurements. Eg in moneyball they weren’t showing that everything the scouts did was completely wrong. They showed that marginal improvements could give them an economic edge. Even a few percentage points of improvement of received wisdom v measurement meant their money was much better spent.

LeonB··on Google's new pipe syntax in SQL
Yeh. Linq to sql was a much more lightweight extension than EF, and was killed due to internal warring at MS.

Database people were investing a lot of time and energy on doing things “properly” with EF, and this scrappy little useful tool, linq to sql, was seen as a competitor.

LeonB··on Deliberate Practice and Acquisition of Expert Performance: A General Overview
Sorry for focusing on the money aspect.

I agree with a lot of your bullet points, particularly your characterisation of faang, but the overall message that a single software developer can’t make much impact is needlessly negative.

Compared to any other worker throughout history you’ve got more access to being able to duplicate your work and to reach more people. A peasant in the 1500s could help just one person at a time. But what’s actually stopping you? You can publish open source software that is not limited to helping 1 person at a time, or create educational content that helps more than 1 at a time and so on, or contribute to existing open source software to do the same. It’s such a privileged position you’re in.

LeonB··on Deliberate Practice and Acquisition of Expert Performance: A General Overview
If your goal is to make a lot of money and to influence a lot of people — you are guaranteed to be unhappy. If you make a lot more money than others, you’ll still make a lot less than some. No amount can fulfil that “goal” because it’s not a goal it’s a direction, like “head west, and keep heading west” … you can’t reach “west”.

Different point of view —

If there are people that you care about and your goal is to help those people - you can be happy and you can succeed. If you only help a few, it’s still worth it, because you care about them. If you help a few more, even better.

If you’re hoping to get rich by helping people who you don’t care about, give it up, stop wasting time. Step back and think about it.

LeonB··on Deliberate Practice and Acquisition of Expert Performance: A General Overview
Studies are easiest to perform on topics with easy to measure results.

But in most any field, if you’re genuinely interested in the field, you will be aware of people who you consider to be better than you. Even if it’s a highly subjective field, as you learn your taste/appreciation grows and you get a clearer picture of what you consider “better”. Those are your potential pool of coaches/mentors. You don’t have to pick just one, either.

LeonB··on Deliberate Practice and Acquisition of Expert Performance: A General Overview
This is a really good question and I’m not qualified to answer it, other than to say “it can be done!” Alan Kay is an example of someone who has a great intuition for answering this kind of question.

My general opinion is that a great coach/mentor can “see” your errors and doesn’t just know what you’re doing wrong but what the best next step is from where you are, to learn the thing that is holding you back.

Deliberate practice never feels easy. You’re always pushing the boundary of what you’re capable of. And you keep going back for more.

Where there are a lot of different styles of doing a thing “well” (e.g. first class lawyer, teaching, writing, 99% of things ) you’ll need to progress through a wider series of different mentors/coaches, sort of “earning” the mentorship of a “better” coach is a good goal in any field.

In fields like you describe it’s not a simple ladder, more like a branching tree of ladders. You’re goal is not just higher and higher but learning (by climbing) where and who is a mentor for you.

LeonB··on Pipe Syntax in SQL
(Minor correction, the plugin is called ‘dark night’)
LeonB··on Pipe Syntax in SQL
I’m not sure if that’s fixed, it seems pretty much “by design”, with the way the editor (in the browser) selects the “current query” for you.
LeonB··on Pipe Syntax in SQL
Good question, I don’t know i’ve only used it for querying.

For SQL to Have a good/improved syntax for insert/update/delete/merge would be very nice (in theory)

I don’t think the formulas are rendered in reader view. (iOS Safari)

In the browser (iOS Safari) I use an extension (dark reader) to give it a dark theme, and the formulas render just fine there.

LeonB··on Pipe Syntax in SQL
Yeh, when I saw the example above I thought it was KQL.

But they do sort of acknowledge it in the paper. Eg on the first page it says:

> …we present a solution – adding pipe-structured data flow syntax to SQL. This makes SQL more flexible, extensible and easy to use. This paradigm works well in other languages like Kusto’s KQL[5]

Strange typo though, to say “Kusto’s KQL” instead of “Microsoft’s KQL”

Kusto is allegedly named after (sort of in reference to) Jacques Cousteau, so “Kusto’s” doesn’t make sense.
