RandomInteger4··on Simplistic programming is underrated
Not my area of expertise, so I want to ask this question: Do compiler optimizations exist to automatically parallelize a for loop, which can be parallelized, no matter how to programmer wrote their for loop?

If not, then map / reduce offers non-trivial performance benefits over a for loop. Mapping, as far as I'm aware, is "embarrassingly parallel", assuming the function that's mapped is pure? I think?

Might look nicer to write the first version as:

  let square = (n)   => n*n
  let sum    = (s,n) => s+n
  
  let r = array.map (square).reduce (sum,0)
RandomInteger4··on Cinemark announces $8.99/mo. subscription to fill more seats, take on MoviePass
This seems like a dark marketing pattern:

Pay $7.50 normally or experience the deluxe super duper savers package for $8.99! WOOOO!!!

RandomInteger4··on Computer Topology and 3-Manifolds pg. 312 [pdf]
Just speculating, but I'd have to assume it has to do with VLSI design and reducing complexity of how wires are laid out on the die in order to increase efficiency.
RandomInteger4··on What happens when patients find out how good their doctors are? (2004)
Concerning your last paragraph, this article is from 2004, so technically we can examine the efficacy of this approach right now if it were utilized.
RandomInteger4··on Philadelphia write-in candidate: I won with one vote
It seems to me like a lot of the apathy comes from the hopelessness people feel concerning their own situation in life. People don't see anything changing for themselves in the near or distant future, so that carries over into something they feel even more powerless about.
RandomInteger4··on Infinitown – A WebGL Experiment
Seems like it's animation related, meaning they intended it to animate like that.
RandomInteger4··on I'm on the FCC. Please stop us from killing net neutrality
Given how well that works for YouTube at the moment, I'm not so sure that's a good idea.
RandomInteger4··on Why I don't support Net Neutrality
You can either have regional monopolies or the ground constantly being torn up by companies wanting to lay their own cables, resulting in a clusterfuck for any other construction effort, and there's only so much space in the ground for cables anyways, not to mention that it's not practical for new players to enter the market given the costs of laying cables, putting them at a competitive disadvantage.

Sure, only 21 states codify telecom monopolies into law, but in the rest without those laws, how much more choice is there? Let's not count the states where the government paid for dark fiber which is leased to the corporations to provide service for customers, because that seems to be taking the correct route. If that were to happen in other states, it would necessarily require either (1) taking over the telecom infrastructure and leasing it back to them, or (2) expensive buyouts of the telecom's infrastructure. It seems simpler and cheaper to regulate a monopoly in this case.

EDIT: Correction: the laws in these 21 states don't codify monopolies per se, but they make it impossible for cities to build their own infrastructure on some absurd basis that the cities are anti-competitive with respect to corporations:

EDIT2: Ignore any argument I was trying to make, as I may or may not have contradicted myself based on my mental shortcomings with regard to concentration and lack of medication.

RandomInteger4··on Members of congress who voted to reverse FCC web browsing privacy rule
Correct, but they can see that you're using a VPN, which they can throttle if net neutrality rules are taken away by the current FCC.

Try ublock origin. I didn't get either a paywall or scroll-blocking. Must be one of the ads?
RandomInteger4··on I'm on the FCC. Please stop us from killing net neutrality
There's a problem with that idea, which is that then the internet is at the mercy of those in congress who want to shut down the government all the time, because they won't pass a budget unless we go on a governmental starvation diet, while at the same time giving tax breaks to the rich.
RandomInteger4··on I'm on the FCC. Please stop us from killing net neutrality
Not only that, but I'm seeing a lot of people mentioning VPNs as a solution when they're really not. Sure VPNs obfuscate your destination, but not the fact that you're connecting to a VPN, and without net neutrality, what's stopping them from seriously deteriorating the quality of VPN traffic unless the VPNs cough up some dough?
RandomInteger4··on Snap’s Rise and Fall: How a Big, Splashy IPO Prompted the Doubters to Keep Mum
Snapchat always seemed like a one trick pony that anyone could easily replicate, which Instagram went and did. Not sure how this wasn't obvious to people.
RandomInteger4··on Show HN: Impostor Roster – Suffering from Impostor Syndrome? You're not alone
Impostor syndrome is mostly marked by the feeling of being a fraud which can run in parallel to feelings of "I know I'm smart, but I feel so dumb compared to everyone else."

It's a constant self-doubt in spite of knowledge of what one is capable of; self doubt that one should be in a particular position, because while one knows what they're capable of, they think they should be capable of more when comparing oneself to one's peers.

One doesn't need accomplishments to feel like an impostor and a lack of notable accomplishments doesn't mean that one shouldn't be in a particular position.

RandomInteger4··on Intel Coffee Lake Core i7-8700K review
This is a random tangent, but I've been meaning to build my first PC and was thinking of going with Ryzen.

Do you by any chance run Linux or Linux dev tools on it and if so have you experienced hard crashing issues that I've been reading about?

RandomInteger4··on The Case Against Civilization
Not sure why I was downvoted for pointing out that parasitic infections are one more negative aspect of not living in civilized society where we have the knowledge and understanding to know how important clean feet and shoes are.

Don't forget the hook worms and other things that don't kill you fast, but still degrade life's experience.

RandomInteger4··on Healthcare.gov going offline nearly every Sunday for 12 hours during enrollment
Numerous people eligible for medicaid don't sign up because they try to and get turned away with some bullshit excuse about not filing the paperwork properly or whatever, either due to innocent bureaucratic bullshit or because the state is explicitly hostile towards government assistance.

With single payer, people wouldn't have to sign up; they would be signed up and have to opt out of they so chose. That's how it should work and it's not hand-wavy in the least.

RandomInteger4··on Healthcare.gov going offline nearly every Sunday for 12 hours during enrollment
Sounds more like an argument for why we should move to single payer, because then the idea of random expenses from sick people signing up goes away, as we'll all have health coverage anyways.
RandomInteger4··on Healthcare.gov going offline nearly every Sunday for 12 hours during enrollment
Why is there an enrollment period at all? Why can't you enroll any time during the year? This limitation makes no sense.
RandomInteger4··on Server: Racket – An ebook about web development with the Racket HTTP server
Why would you need a text editor to come with the language when you could have Vim and the rest of the command line. The problem newcomers have with programming is that educators think they're too stupid to use the command line and in the process they shield them from important details about the build process by obfuscating them under the veil of an IDE.
RandomInteger4··on The Impossible Burger
Beef before it's cut has the potential to have harmful microbes on it's surface, but they don't travel very fast, so they can't get deep, which is why it's safer to cook to a lesser degree than ground meat.

Ground meat on the other hand can introduce those harmful surface microbes to the rest of the meat, so burgers have to be cooked all the way through to ensure those microbes are successfully deaded.

RandomInteger4··on The Impossible Burger
Who the fuck wants their burger to bleed? Seriously, why is this a thing? If it were real meat, I'd be even more concerned if it were bleeding, because undercooked ground meat is one of the worst things you can put in your food-hole.
