hyperpallium··on Anti-selfconsciousness theory – John Stuart Mill

  Ask yourself whether you are happy,
  and you cease to be so.

  The only chance is to treat,
  not happiness, but some end
  external to it
  as the purpose of life.

  Let your self-consciousness, your
  scrutiny, your self-interrogation
  exhaust themselves on that.
hyperpallium··on There is one, and only one strain of SARS-CoV-2
Thanks. I did say it was only "suggestive".

A series of similar events in similar circumstances can be explained by a series of different causes, but it seems worth looking at a similar cause, no? This is at the stage of initial hypothesis.

Gosh, maybe people thought I was saying it was the absolute truth.

hyperpallium··on There is one, and only one strain of SARS-CoV-2
Wow, HN is strange sometimes. Have covid19 strains become political/tribal somehow?

I'm just pointing out something interesting in the data I was curious about. It's a pity HN picks out one detail and ignores the interesting thing... but upon reflection, pedantry is typical of today's HN, and partly why pg withdrew.

Regarding Australia, it's often said we are in the Asia region. And for the specific purposes here, of initial transmission, we have much contact with China, through tourism, education, primary produce and trade in general. It's expected we'd get initial infection direct from China (which trwcing shows we did), rather than via Europe.

hyperpallium··on There is one, and only one strain of SARS-CoV-2
The hypothesis is the mutation occurred outside of Asia, and countries in Asia closed ports after the initial infections, but before the mutation.

> sunlight (UV-B), heat/humidity

Much of Asia is in the northern hemisphere (e.g. China and Japan); same season as Europe and USA.

Australia is in Asia too, close to China with much travel between.

I agree there are many factors and it's early. But the low cases and deaths over all countries in Asia has a peculiar uniformity - in contrast to elsewhere.

hyperpallium··on There is one, and only one strain of SARS-CoV-2
Cases and deaths in Asia (N & S hemispheres, 1st & 3rd world) are significantly lower than elsewhere.

> So far no one has shown that any of these virus isolates differ in any fundamental property.

A different sequence is prevalent elsewhere. Not proof, but suggestive of a property difference.

hyperpallium··on I was tricked into thinking I had “grit”
> isn’t because of grit, ... It’s because I enjoy doing them

"Enjoying doing" is a gift, like a talent. Considering division of labour in a society, maybe each should use their gifts?

An exception is needs, as in the article: diet, exercise, sleep ... but also things you need to do in order to get to the things you enjoy doing...

Having both "I enjoy programming" and "12. Programming" may be an example of that.

hyperpallium··on What Makes a Good Teacher? (2001)
Diagnose before prescribe.

Student is lost with only you on a walkie-talkie. You need to know where they are to know what instruction to give.

Gaps and misunderstandings must be identified to be corrected. It's debugging.

This is all very intensive, customized, one-on-one teaching. But there's no reason it can't be automated... in principle.

About non-algorithm competitive advantages. It's easy to switch search engines, so google invests madly:

Capital - massive capital investment in data centre around the world, for low latency, particularly for Google Suggest. Capital is an enormous barrier-to-entry for web startups. Google made search capital-intensive.

PR - consumer habit, supported by those myriad projects that position google in consumer minds as "leading tech company". It matters that you are the best; it matters that decision makers know you are the best.

Data - being first gives you a headstart, but competitors will catch up if you don't run at least as fast (and ways to improve that consumers care about - more running track). If you can something you have to do this that competitors lack, it's easier. So google madly collects data, and uses it to e.g. NLP of queries

Backend - Sergy did a lot with little hardware in the beginning, and that has continued, I believe including their own silicon.

All that gives google time to rival better search - and money buy it.

hyperpallium··on 68 Bits of Unsolicited Advice
> When an object is lost, 95% of the time it is hiding within arm’s reach of where it was last seen. Search in all possible locations in that radius and you’ll find it.

Yup, look closely in the place you expected it to be. Something may be on top of it, or it may have fallen off.

hyperpallium··on The Diminishing Returns of Everything
Extreme programming's "tracer bullet" is sort of a way around this, by implementing a minimal subset of functionality all the way though, so it "works".

The diminishing routines then come when expanding each stage. But at least you have the encouragement of being in post-phase-transition. This is like a MVP or Mark Cerny's "Method", but for motivation, not evaluation.

also, straw that broke the camel's back

hyperpallium··on Let’s Invent B(+)-Trees
Thanks, makes sense! I've once before seen comparing sorted values is faster, even when not all match.

If "building an index" means it's just the indices (not all rows of the table), doesn't that indirection mean an extra seek to get the full row? (I probably have a fundamental misunderstanding here)

hyperpallium··on Let’s Invent B(+)-Trees
Thanks, sounds like sorting is an implementation detail, and not the main benefit in itself.
hyperpallium··on Let’s Invent B(+)-Trees
I understand that B+ trees made relational databases practical.

Is that true? How are they used (sorted, according to link)? How do B+ differ from B trees?

hyperpallium··on Wi-Fi over Coax
If the boy who cried wolf was fined by the townsfolk, he'd be incentivized sooner to stop, and they'd still be motivated to turn up. This doesn't work for impecunious boys, who under this theory should be left to the wolves.
hyperpallium··on Supreme Court rules Georgia state law annotations not copyrightable [pdf]
Copyright is abused, yes. People want to write anyway, yes. But you need time and resources and space to write, review, edit.

Some novelists spent years collecting rejection slips (e.g. Stephen King; Larry Niven did it full time with a trust fund), which is probably irrational. But with no pot of gold at the end, only the properly delusional or wealthy could justify that investment.

OTOH copyright enforcement isn't that effective, so publishers meaninglessly vary textbook editions yearly, with expiring access to essential online content.

hyperpallium··on Ask HN: Not smart enough to a programmer, where to take my life from here?
Diagnosis: bored.

See other comments on interest. I'll address your thoughts. You're speaking casually, but your exaggerations can be dangerous when you're vulnerable:

> nothing sticks.

Not literally true that "nothing" sticks, since you later mention things you recall.

> I fail to understand, fail to recognize patterns

There's partial understanding and levels of understanding. You can notice progress by comparing your present understanding with before.

> am too slow to understand simple concepts

Here you admit you do gain understanding, but dismiss it. What is the threshold for fast enough?

> and never retain anything.

Again, not literally true that "nothing" is retained.

> Occasionally understand the individual concepts of something but then her completely lost when they're all combined in some applied method.

Again, you admit understanding, but dismiss it because of difficulty in the next step. Also, "completely" lost is not literally true.

---

These casual exaggerations are dangerous when you start to believe them, because they aren't literally true. Changing them won't solve the problem completely, but you'll see it more clearly and that helps to solve it! Advice:

  notice what you _have_
  retained/understood/applied
  (especially in contrast with before)

hyperpallium··on Dissection of COVIDSafe (Android): Australian government's contact tracing app
Not disputing, but do you have a link for when they got source?

Opentrace was open sourced 16 days ago https://github.com/opentrace-community/opentrace-android

hyperpallium··on Dissection of COVIDSafe (Android): Australian government's contact tracing app
>> You can release you code as GPL. But you can also release you code however, separately if you want.

OP meant Singapore can dual license.

hyperpallium··on Dissection of COVIDSafe (Android): Australian government's contact tracing app
They said they would release source, but they've distributed the app first, so are in breach.

They also said location would not be used, but

Can't trust them on things that can be checked; therefore can't trust them on the things that that can't be checked.

hyperpallium··on Time is the only real currency we have
This is great if you will never have an economic rival or military enemy.

There's a strong argument that not aiming at immediate productivity produces better productivity long-term (e.g. fundamental science, pure mathematics), but that still holds productivity as the primary value.

But what value survival if we lose our humanity?

A resolution is that our intuitions of morality support probabilitistic long-term survival, even if it doesn't seem so in the short-term, shaped as they are by evolution.

The inequality is legitimate.

hyperpallium··on What Declarative Languages Are (2013)
From abstract of an earlier paper co-authored by Reddy

> A mode of a predicate designates some of its parameters to be input and the others to be output. ... indefinite modes... in which a resolution interpreter yields answers with free variables. https://www.tib.eu/en/search/id/tema-archive%3ATEMAE84100273...

Sounds like well-moded means: for given inputs, you get a definite answer, rather than something to be further computed around (like high school algebra with more than one unknown). Fits the context here.

hyperpallium··on What Declarative Languages Are (2013)
The latex isn't rendering for me. Pasting it into https://math.stackexchange.com/questions/ask is one online solution.

In the example, membership in a language already implies existence, doesn't it? So why is the (crucial) existential quantifier needed?

What does "moded" mean (as in "well-moded")?

hyperpallium··on Are Ideas Getting Harder to Find?
There's certainly phases of progress in particular fields. e.g. in physics, we had relativity and quantum mechanics... and no further revolutions for quite a while. If Einstein's genius made some of it possible... he also didn't make further progress. He was older yes, but also perhaps there was less to find? Other people were smart enough to find what he found, but weren't bold enough.

Looking at the bigger picture, Einstein had unexplained empirical evidence (speed of light constant in all directions, inconsistent with waves in an ether). So that was a driver.

Looking bigger again, even with better equipment, that senses further, we can only discover new things if they can be sensed with that equipment.

(Without evidence) my opinion is we will have periods of slow progress and periods of rapid progress. We are currently in a period of stagnation. We need empirical data, intelligent analysis, and boldness.
