I'm really into functional programming and I gravitate toward Elm and away from PureScript and Haskell.

Fundamentally what appeals to me about Elm is the design sensibility of "what is the minimal set of primitives necessary to achieve a great user experience?"

Over the years Elm has gotten simpler and nicer at the same time. The last three major releases removed language features.

I love that! Building software is complex enough as it is; one of the things I like most about FP is that I no longer have to spend time thinking about objects, classes, inheritance, etc.

It frees up more of my brain to focus on building things!

This is so naive.

You think WhatsApp of today is the exact same app or backend server logic from a year or two ago?

Any online service is constantly adding functionality on the server side even if the app code is constant ( given its a mobile app this is simply unlikely)

Unless you have an app that's not been upgraded and running in offline mode it's definitely not doing the same thing as a year ago.

Here’s an article summarizing the findings of the most headline-grabbing medical study of the ISS program, the Twins Study in which Scott Kelly spent a year in space while his brother Mark remained on Earth; both were subjected to exhaustive testing, and the article briefly covers each investigation. One that I found particularly interesting: Scott’s telomeres grew significantly longer while he was in space!

Most astronauts spend six months on the station, and obviously most of them don’t have a twin, but they all add data to our knowledge of how space affects humans. We have learned a lot about how to counter muscle atrophy, and we have a better understanding of how the eyes and bones are degraded by prolonged weightlessness.

NASA loves to talk about ways that space research has improved life on earth (just google it, they’ll shout it at you), but even if you could find a way to do all that other research without a crewed space station, you can’t accumulate six astronaut-years of human medical data in space every single year for decades on end unless you’ve got a place in space to put a bunch of humans for a really long time, over and over again.

To me, that is what makes ISS a human treasure. Someday we will build a more cost-effective replacement on the basis of the lessons we’ve learned, but for now it’s the best we’ve got, and it’s quite good.
Seems to me like you’re focusing on the word stupid which is actually fair in this context
Even if they're not reusing any of it (this time), it's still very useful to examine and analyze how well it's held up.

Perhaps some piece of metal is showing more fatigue than they'd like to see, or a wire had damage to the insulation from a vibration. I'm sure that's the sort of thing they'll be looking at.
You really kicked the crap out of that poor strawman. I don’t think that many people who know much think that any one tech can “save humanity” in the first place. Solar has a role to play, along with wind, fission, and hopefully fusion.
I notice a lot more of what I'd call the "fallacy of progress" - the idea that because humans did more of something in the past, it must be outmoded and not worth doing. Exercise and fresh air are still good for you, even though cavemen had much easier access to them than modern urbanites.

The post says that if a compiler can prove "that the lifetime of the coroutine is indeed strictly nested within the lifetime of the caller", it would be able to avoid heap allocations. It makes it sound like an optional optimization, though.

I think Rust clearly has an advantage here: since lifetimes are well-defined concept in the language itself, it should also be well-defined whether a generator can be allocated on the stack. Of course, I'm probably missing some hairy edge cases here.

Another aspect I found interesting was the ability to define custom code which runs every time a certain coroutine is suspended, or returns. In my reading, this allows for the coroutine to e.g. manage its own membership in a resume queue.

Tokio tackles this problem differently, but is this more powerful than Rust coroutines? Is there a mechanism by which a generic type could be used to wrap a generator and provide this functionality in a similar way? Asking partly as a point of conversation, and partly as someone who isn't fully steeped in Rust's type system yet.

It's worse than that. My gaming PC was top-of-the-line six years ago, and it still works great for browsing and work tasks, and runs many modern games effectively on lower settings.

My Samsung Galaxy Nexus phone was top-of-the-line six years ago, and is essentially useless now. Just switching from an app back to the homescreen takes multiple seconds, and launching or switching between apps often takes upwards of 15 seconds. It takes more than half a minute to start Kindle Reader and open a book. These are all things that happened almost instantly when it was new. I've wiped it and reinstalled Android multiple times, and it only helps a little.

Worse yet by far - I'd have to double my grocery bill because I'm cycling like a maniac. And groceries have the largest carbon footprint of anything you can do. Its arguably more carbon efficient to drive to work, even a few blocks, than walk or cycle and eat more.

I don't agree with this. You don't have as much control over yourself as you think you do. Your genes and your environment play a huge role on how you act and behave. Of course I am not saying that you shouldn't take responsibility for your actions--you should. You should see where you went wrong and try your best so that it doesn't happen again. If you observe your emotions closely, you might find that berating yourself is often a way to 'feel good' (oh look how self aware I am, how virtuous I am for recognizing my mistakes) without actually accomplishing anything. And research backs this up. People who berate themselves over mistakes are less likely to implement behavioural changes.

It is inevitable that you'll make mistakes. You'll make mistakes everyday. So it is best to accept this and get over yourself--to focus on improving yourself. I like to think of it as treating yourself as you would your best friend. If your best friend makes a mistake you wouldn't berate him, nor would you encourage him to keep making the same mistakes. You would instead, with compassion and respect try to help him out.

Disclaimer: this post might sound kind of righteous and condescending. But that's not my intention. This is based on my experience with my own self. YMMV
Seeing as I can still watch kids make backyard flamethrowers and attempt to break bottles over their heads, it's interesting that this is where YouTube chooses to make a stand. Is this politically motivated, i.e. pro-gun control? If so, that is not good. The last thing I want my tech companies deciding is what constitutes free speech. This huge anti-Silicon Valley backlash has very dangerous unintended consequences.
"I'll apologise for eating your apple when you apologise for being late and making me wait."

That is a basic example. This isn't going to be a genuine apology, even if the apple-eater says sorry it is in context of something more akin to a negotiation.

There is an implicit "if you cause me trouble, I am morally free to eat your apple in retaliation". There is no element of regret or mistake in this 'apology', which robs it of genuine impact.

Incidentally, that sort of negotiation in this example is a bad idea because it immediately entangles actions (eg, being late), guilt (something has happened that demands an apology, ie, hurt must be immediately acknowledged) and a level of threat (future actions may still be met with retaliation because it was justified this time).

If you reflect on that little 'apology' you can have quite a fun armchair psychology experience picking apart all the ways it conflates emotion, intent and action in ways that are unlikely to be helpful. Using the same approach on a subject more important than food can cause real damage. Many people would probably struggle to pick what was going wrong though, because on the surface it might look like an apology.
First rule of the Wallowas: Don't tell anyone else how awesome it is there, we don't want an influx of people. ;-)

But, I don't blame you for filtering wherever you are. The risks in general aren't worth it.

Python’s Weak Performance Matters
"ladies and gentlemen, we are floating in space"
I think that "niche" is what you share with most people under 19 or so as of today.

People are quick to write off Snapchat's popularity with young users as it being the hot new toy they will tire with, but I think it's a lot deeper than that. They see the mistakes of millennials and older with social media and want nothing to do with it (and are thus nowhere to be found on Facebook, yet still on Instagram because it hasn't suffered the same problems yet). Snapchat avoids a lot of those pitfalls, though of course not without other problems. I think so long as that impermanence is the focus, and they allow for easy/simple communication between close friends (I'm worried about the non-chronological part for this exact reason), they will be a big part of the future of social media.

Facebook and the apps it owns have all tried towards that, but if the core is permanence (the classic profile, posts, walls, likes, comments), they will always be fighting a rising tide. Adding stories on top of that doesn't change the core use of the app.

Thanks everyone, some useful thoughts there. The "ultra low cost" comment was just recognising that the value of the tech here would be compared to the staff expense of building it yourself. It would just be saving some precious dev time, but not enough to charge $1000s for it.

I think it's a fair point though that only a small percentage of customers actually use webhooks, so the value is further constrained by that.
I don't feel qualified to judge whether it's explainable or not. But 2 guys familiar with the matter believe it is not :) Not that I appeal to authority, it's just to demonstrate that the jury is still out.

Yes, I remember this. Had stayed up all night to watch the launch. After the side cores landed (which was mind blowing honestly), the cameras switched to drone ship where the center booster was supposed to land. The only thing I could see was mist & fog, and they switched to their commentators 2 seconds after that. Thought I must have not noticed the successfully landed core, & went back to sleep dreaming of the cool life Musk lives.
My impression is that a lot of programmers have already followed a similar path, would like to find a job doing ML, but haven't found a way to make it happen. Does that sound correct? I'm not saying the effort isn't worth it anyway.
What is Galilean invariance? You are below deck in a ship moving uniformly on a smooth sea. No experiment can tell you if the ship is docked or if it has motion relative to the see. Assume that the ship is docked. In that case you say that the ship is at rest. And you attribute to the ship some properties because it is at rest. But is the ship at rest absolutely? Not at all. The ship is moving with the earth. So do you deny that the earth is moving? I assume not. If so how can you claim that the ship is at rest?

Motion is absolute means that all is in motion. This is an axiom. When you say motion is not absolute, can you give an example of an object which is at rest, which does not move with the earth and does not move with the galaxy? There is no such object.
To all the people saying apologies are worthless, you probably feel that way because you get too many worthless apologies.

Personally, I don't count it as an apology unless they acknowledge how they've hurt you, expressed remorse, and made a commitment to change. I've known many people who can only manage the first two (at best), and it drives me insane.
If you think that being a female engineer is like being short in basketball, then there are clearly serious problems with your mental model of the world.

Correct, the engines were going to be retired anyway but they are keen to reuse the titanium grid fins on the boosters which cost a small fortune to make.

The core actually had older ablative grid fins made of aluminium so no great loss there[0].

Explain why it happened (with sorry early in the explanation.)
Explain how your decision making has now changed or will change so it doesn't happen again.

Don't get the scope wrong - if you are only going to make such a minor change that lots of almost-identical incidents will still happen in future, don't bother. Conversely, if you make quite exaggerated claims about the change you will make, also maybe don't bother.

If in contrast to a real apology that promises change, your "apology" is really a backhanded promise that it'll all happen again and probably soon; don't expect that to be gracefully accepted.
some sci-fi was never connected to the future. But when it comes to Arthur c Clarke and Neil Stephenson, I'd have to disagree.

> Motion is absolute means that all is in motion

That's not a usual use of “absolute”; “motion is universal” would be the normal way of expressing that idea.

> This is an axiom.

Well, you could have an axiomatic system in which that was an axiom, but I don't see why you would want to.
This. I repurposed a dell t3500 with a xeon x5650 (https://ark.intel.com/products/47922/Intel-Xeon-Processor-X5...) GTX1060 6gb and samsung evo ssd, and the thing is still quite fast running ubuntu Mate and windows 10 LTSB.

The only real obstacle is the lack of NVME support. SATA3 is a bit of an upgrade bottleneck on these old systems, but even software development on this box was just fine with a fast ssd.

NASA spent 72 billion 2010 dollars on the ISS [1]. (Total cost is over $150 billion.) From Expedition 1 in 2000 through Expedition 53 in September, the ISS played host to 25,290 crew days of human occupation [2]. That comes to $2.8 million per day for NASA or over $5.9 million more generally. (Remember: this does not include the cost of getting to nor from the ISS.)

The Apollo program cost $107 billion 2016 dollars [3], or $98 million 2010 dollars [4]. (This includes the cost of the Saturn I, Saturn IB and Saturn V launch vehicles.) From Apollo 7 in 1968 through Apollo 17 in 1972, the Apollo program hosted 305 crew days of human spaceflight [5]. That comes to $3.2 million per day.

TL; DR We could have replicated the time spent on the ISS with a series of Apollo programs, using Apollo technology and Apollo-era costs, and had budget left over for a manned (probably non-landing) interplanetary mission [6].

The ISS is a boondoggle [7] on every measure except number of dollars funneled to defense contractors. It's not fun to trash these programs. (I grew up adoring the Space Shuttle and the ISs.) But over time, I've realized it's necessary. We cannot correct failures we refuse to recognize.

[6] Keep in mind the degree to which I'm putting my thumb on the scale in the ISS's favor. We're counting the Apollo program's launch costs but not the Space Shuttles. We're including, in $2.8 million per day figure, everyone's crew member hours but only NASA's costs.

[7] I am not (yet) in favor of de-orbiting the ISS. Sunk costs are sunk. Looking forward, there is probably something useful to be done with the beast.
I remember watching the artists impression animation video of how the the falcon heavy launch and landing would proceed, and when it showed both boosters landing at the same time I thought "heh, I wonder if they'll be able to pull that off in real life", and they did! Almost identical with the animation.
