Not to mention the fact that dithering will look different depending on the display’s gamma calibration...

“It’s not real engineering if someone can’t get hurt” seems like a strange definition to me.

What’s flexible for a dynamic scripting language is often cursed from a static perspective. Knowing what imports resolve to statically can be nice.

The problem is that “radical” is in the eye of the beholder. If a language is so poorly specified that developers and the specification don’t agree on the meaning of a program, that leaves optimizers in an unwinnable situation.

That can be fixed by using “EDITOR=true git commit --amend --allow-empty”

Eventually, a long enough ship should be supported by 3 or more waves at the same time, assuming waves have some sort of maximum wavelength. (Disclaimer: no idea what I’m talking about)

The fact that CompCert, seL4, and similar projects exist is proof that a large amount of composition is possible if you have enough time to spend on it. It’s true that you can’t compose arbitrary formalizations, but you can architect your f

The ISA alone doesn't mean much, but there's OS compatibility too. MacOS will run iOS applications out of the box.

So what you're saying is that we need more militarization of the police?

True... but I think it’s just called an “investigation” when done by the authorities.

You were downvoted because you stepped into a long-running and bitter ideological war: Bayesians vs frequentists.

As far as I can tell... Bayesian statistics is a model of the real world, fuzzy logic is just an easy to compute, bad approximation of reality that assumes everything is independent. (Someone correct me if I’m wrong; I’ve only studied logi

Cool! I've recently started writing many of my shell scripts in swift [shameless plug], but nice command line argument processing was something I wasn't looking forward to tackling. Now it looks like I won't have to :) [shame

That’s some good, bad sci-fi waiting to be written. A new strain of the flu spreads overnight across the globe once it is able to jump between people and the internet...

I can tell the difference at 12. There's a flash test at http://jakemandell.com/adaptivepitch/ and the (probably heavily sample-biased) histogram at the end suggests 10-20% of people can't differentiate 1&#x2

It's two different processes. Normal counting is saying, "take a thing and add one" (a successor ordinal). It's how we get from 42 to 43. If a number can be reached from zero using just this kind of counting, we call it

Call stacks are almost always used in implementations of functional languages as well, even those that support first-class continuations. Even implementations that use CPS as you describe don't necessarily lose call-stack discipline (e

Looks like a variant on ml-like `let`. let <variable> = <expression 0> in <expression 1> will bind the value of expression 0 to variable in expression 1.

A likely reason is that it makes it possible to iterate through a list like `'((1 2) () (a b c))`. If you have to do in-band signaling, make it something unique and obscure.

I was getting that error until I disabled the "HTTPS everywhere" extension for the page.

Oops, looks like I made several mistakes in the above calculations. For a 768 bit number the primes would be 384 bits each, gaps between numbers of the form "27a^2 ..." would be 10^58 apart, and weak primes would be at worst one o
232.
by cobbal 9y ago
Assuming at least 768 bits (an RSA number of this size has been factored), the gaps between such numbers are more than 10^232. Even if every number of this form was prime, the prime number theorem tells us we can expect one out of every 10^

RGB isn't white, it just looks that way to us. True white has every frequency in it. Color is an infinite-dimensional space since you can have any amount of any frequency EM waves. Humans eyes reduce that infinite dimensional space to

Interesting. I still think it would be hard to apply to a ref counter app, since you'd need to keep track of change in ref count for later cleanup (thread-local per object maybe? sounds inefficient), but I now will admit that it sounds

Possibly, but it's very handy to let immutable data be read by any thread that wants to. If, however, it's very slightly mutable due to a ref counter, you have to atomically manage the counter, even for what should be free immutab

It's probably not that much, on a global scale. What's more, CO2 is a better gas to be venting to the atmosphere than methane is. [citation needed]

I usually try to stick it all on one line when I have to do that, something like ssh somehost 'cd /some/dir; grep -lr foo .' | pbcopy not very flexible, but it works for many cases

With the right zsh plugin, either of them will tab complete properly. (I think "osx" from oh-my-zsh is the one that does it on mine) Edit: looks like this is actually built into zsh. Slightly surprised, but just goes to show I kno

Linear in this case means y = m * x. The relationship between Fahrenheit and Celsius is affine (y = m * x + b) For gory details: https://en.wikipedia.org/wiki/Affine_transformation

From the article: > In my experience, the spiped tunnel is highly reliable and recovers more gracefully than a standard SSH tunnel. I've never had an issue with ssh -D though
