bsdpufferfish··on Car insurance in America is too cheap
They are not at all random. In fact almost everyone’a insurance is more expensive because insurance companies are not legally allowed to use the highest predictor of risk besides age.

Exactly these people are more likely to be spending their time speed running Mario.

Of course they aren’t familiar with the literature. Most of the papers rediscover existing math and physics in a worse way (harmonic analysis, etc)

Most CS papers are theoretical, and this is another reason why HN is wrong about requiring papers to publish code.

This is not even close. Pure math is often complete clueless about how it applies. For example Developing algorithms to compute properties used in the most basic pure math is a massive pursuit.

Nope.

Just use C and guarantee your sanity. The whole reason to adopt C++ is to support huge projects and libraries all of which are going to use the “bad” stuff.

I don't think it's even close. Benchmark game is one (biased) reference. And it's even worse because optimized Java is not canonical Java. Canonical C++ is pretty fast.

If Clojure is a lisp, so is JavaScript.

Being selective means they can start further, go faster, and expect motivation.

Even if the value is coming entirely from your fellow students, that has no effect on deciding which school you want to go to. You want to be in that environment, and also get the status from the exclusivity.

So your claim is that a new language could define a spec to a degree that it would not have similar problems?
bsdpufferfish··on 'God' is the average opinion of your tribe
A few points.

- The founder's didn't even believe in the Bible, likely including George Washington.

- Stated vs revealed preferences are complicated among politicians.

- being jewish clearly has an influence on politicians and businessmen who identify that way, and they often make reference to it. Can you give an example of a president or supreme court judge revealing that kind of influence? George bush doesn't even believe religion is the root issue in the conflict with the Middle East.

The claim that is addressing is that religion is the mean of popular belief. How does that account for the Catholic experience? Catholics are obviously a minority among American christians and have less political power.

> The latter, broader, category is the majority of the population across the USA.

Indeed. However they are not organized in any way. The percentage who has been to a church more than 3x in their life is probably significantly lower.

So where does this enormous power exist in the US? What powerful institutions or media influence do they control?

How would Catholicism represent the mean of public opinion?

There is a specified rule and popular posts are constantly removed for allegedly breaking it.

This post and the commments it attracts seems more appropriate for /r/atheism. It’s not technology (what about a stripe scam pastor?) and it’s not something interesting that wouldn’t be peddled in gossip journalism.
bsdpufferfish··on 'God' is the average opinion of your tribe
Exactly. A huge component of Christianity is separation from the world and standing out against a crowd.

There is certainly a popular folk religion, but this is not the essence of religion.

bsdpufferfish··on So you think you know C? (2016)
Yes the CPU is vendor defined behavior. However they usually write a spec.

The point is “undefined behavior” is more about gaps in the standard than bugs in programs.

bsdpufferfish··on So you think you know C? (2016)
Competing languages don’t have spec, so their entire operation is unspecified. If they wrote it down then they would also have UB.

Indeed however this is the exception, not the rule. The general way to do an existence proof is to construct it.

If you read old cybernetics writing it’s hard not to see a striking analogy with the excitement around machine learning. They had all kinds of medical experiments showing the usage of feedback mechanisms on the body and brain and how they were just on the edge of unlocking artificial humans.

> leading to overcomplication and obscurantism

Mathematicians attempt to express ideas in the most readable and clear way possible.

It's actually code that must be obfuscated by the constraints of the language and computer. Mathematicians have no constraints preventing them from presenting something in the way that makes the most sense.

The part that can be called "Obscurantism" is when they use a high-level abstraction you are unfamiliar with. This is mostly driven by the audience.

> Indeed, 99% of pure math is non-constructive

Citation needed?

> the algorithm converges in O(N) steps

That doesn't sound non-constructive. Even the group example is usually done by constructing such a group.

Also the best part about math is you can use it to approach the problems you want with constraints you want. Knuth uses math to solve real CS problems.
