I use Debian and love OpenBSD.

m4r35n357on How to average floating point numbers (2015)

Or can we sum more accurately by taking the stable_mean and multiplying by n?

m4r35n357on The Raspberry Pi 4 has a fan now – the Case Fan

1. Use good quality cards

2. /tmp on tmpfs

You're welcome.

m4r35n357on I've now played with a Raspberry Pi 400 for a week and here are my conclusions

1. The 400 is faster than the 4 OOTB, and can be overclocked easily. 2. The 400 runs much cooler. 3. 4GB is plenty ;)

m4r35n357on What gravitational-wave events reveal about the Universe

Looks like things started to get _much_ better after Virgo joined. I assume that is because of the increased "baseline" (angular resolution) and because two different instruments at different locations makes it easier to detect & reject spurious signals.

Guess . . . . "Because the rest of the commentors in this thread seem to not be reading the article"

There is no opportunity to read this information before . . .

m4r35n357on So you want to build an embedded Linux system?

You want "to use mature distro, with thousands of packages, with known bugs fixed, with fresh software, like Fedora." on an embedded system. Really?

m4r35n357on A Family of Better Random Number Generators

TinyCC example in README is wrong, should have trailing '-': as in "cat pcg_basic.c pcg32-demo.c | tcc -run -"

m4r35n357on 14,000x Speedup (2015)

You could get arbitrarily large improvements by starting with even worse code ;)

m4r35n357on LLVM 11.0

Yep, that is a highly significant feature!

m4r35n357on The Weakness of Anthropic Arguments

OK fair enough, to me the opposition to the weak AP just seems to be people "unhappy" that a physical constant should need to be that precise.

In other words, for some reason they expect the universe to be more "understandable" or "sensible" than this . . .

Of course the strong AP is ludicrous in the extreme ;)

m4r35n357on The Weakness of Anthropic Arguments

Isn't this just a form of "survivor bias"? I don't get why anthropic arguments are considered "weak".

The article seems to just be complaining that anthropic arguments cannot explain the precise _value_ of the fine structure constant. Well, nor can Occam's Razor, but we don't seem to have a problem quoting that!

m4r35n357on What the world can learn from the UK's A-level grading fiasco

m4r35n357on Inheritance in C using structure composition

Dumb but genuine question from a non-expert programmer:

Most of the "OO" world seems to have abandoned inheritance as an anti-pattern in most cases (apart from genuine "is a" relationships).

I'm guessing the two case studies are in the list of exemptions from this rule.

So, is this considered a generally good thing to do in c?

m4r35n357on The event that eventually led to Newton writing and publishing the Principia

Wow, I know Hooke was a complete dick to Newton over the optics, but I didn't realize he tried to shaft Newton _again_.

m4r35n357on Web Dark Ages

Brilliant!

Historically, this was the start of an important process. That of turning a fully functional multimedia access and delivery network (the WWW) into a money-extraction system.

But Web 2.0 was just around the corner to solve that problem . . .

m4r35n357on The caretakers of Sealand, the most stubborn micronation

Hilarious stuff!

D has a native IDE and working REPL OOTB. They are all jealous!
