Perspective people, perspective.
Man that strikes close to home! Breaking invariants when nobody observes it.

I did something in this spirit in my Lisp dialect.

I broke the invariant which says "no matter how you terminate a form, the unwind-protect cleanup forms get called".

I broke it by introducing the concept of "absconding": leaving a scope in such a way that the local resources tied to lexical/dynamic contours are left alone. No unwinding calls are done.

The justification is precisely that it is OK if the scope is later re-entered (specifically: restarted via revived continuation). The revived control then finds everything intact --- and can leave the scopes normally at which point the cleanup does take place.

By doing this, I solved the problem of how to integrate continuations with scoped resource acquisition/cleanup, without the horror of dynamic-wind or its ilk.
Disagree. Just need an outlet, like the engine block heaters on light poles in Minnesota. Infrastructures costs are low of people use their own chargers.

So the solution is to tear down our cities, abandon our homes, and rebuild everything somewhere else. Gotcha. I mean that's probably environmentally friendly, right?
Sometimes it's just fine though. It probably depends on the up-front cost, and what value you derive from it. If Spotify stops working tomorrow, I can stop paying them, and we can all go home friends. I wouldn't consider my subscription fees over the past couple of years "lost".

On the other hand, if I had to buy a $1000 device for the privilege of paying them $10/month, my anger level would probably depend on how many years I got utility out of that $1000 device before they shut down.
Think of it how the heart adapts to effort. A person who is well rested can have his heart change quickly to the environment or effort. The person is more alert, can pump blood to any desired organ etc

Meanwhile a person who is tired or sick or under stress will have more trouble adapting to the environment. Whatever happens, the heart beats at the same exact rhythm - but it shouldn't. It should go fast when required and go slow otherwise

I think the audience is the problem. Java devs prefer Java and Haskell devs prefer Haskell. Aside from some rare open minded individuals and people who have to write java, but would prefer to work with Haskell, Scala is up against a tough crowd.
It isn't in DrRacket by default but it is a common enough requested feature that they keep an example of how to add it in the documentation.

I'm guessing that if you do something to improve your health enough that it adds years to your life, the rest of your health should be improved as well.

Meaning, maybe standing also improves your back and you ache less in later years.

It's hard for me to imagine doing something that improves your life expectancy at the expense of some part of your body.

This is massive speculation on my part.
Good point. I'll change.
To some, it's the same as asking if you'd rather eat tasty meals and live until 62 - or never enjoy what you eat, and constantly torture yourself with exercise, and live until 80.

May you maximize both your years and your prosperity.
Every single description I've seen of bresenham uses integer co-ordinates, which is not enough in modern pipelines that all use subpixel resolutions.

The modifications required to make it work properly for subpixels are not hard; the question is still what axis the next step is; but I've never seen them described in an article.

Ha! It's funny (and great!) to be featured there. The particulars of the naming convention are pure preference I suppose (and I recently simplified the naming of files [perhaps to the detriment of convention?]). I'm still trying to figure out proper naming conventions though and I'm not completely consistent. This makes the automated documentation generation I've tried to put in place hard...

Anyway I'd like to point out that the namespacing exists at all because all structures in Standard ML are global by default. Some implementations have compilation managers that allow you to hide certain exports but Poly/ML does not. In general, if I define a String structure, I just overwrote the Basis String structure. (Ponyo exports a Basis structure up front that exports all overwritten Basis structures so you always have a way back). You could always overwrite these yourself, but _Ponyo_ itself prefixes all structures with their path for pseudo namespacing. But Ponyo also exposes them in a hierarchy for ease of use (the Ponyo structure embeds the Net structure which embeds the Http structure, etc.). But the original named structures are still accessible too. The worst part is signatures and functors. In the Standard ML standard, functors and signatures cannot exist inside of structures. This is a pain in the butt... And some non-standard extensions exist to support this (at least in SML/NJ maybe also in MLton). So in those cases you must ignore the structure access convention (Ponyo.Net.Http...) and use the full real name (Ponyo_Container_Dict). So in the worst case it's C-like (with only string/prefix "namespaces") and in the best case you can access and make shortcuts to intermediate structures (structure H = Ponyo.Net.Http).
EV is fundamentally and objectively better as well. Heat, noise, maintenance/fuel cost are lower. Acceleration higher.

Contingent on low battery prices which make range and charge rate competitive.

Opening up the auction to private individuals doesn't bring more buyers, as the brokers are just middlemen -- all the cars they buy get passed on to end customers in a matter of weeks. It may bring more money, if people are willing to pay more to disintermediate the brokers.

However, this adds a lot of headache and risk for the auction operator - tons of uneducated customers who won't be able to pay, try to back out of bids, get pissed when the car has defects (auctions are typically as-is affairs), crowd the lot, etc.

However - if you see a car you want coming up, try asking a local broker to buy it for you for a flat fee, a few hundred bucks over the closing price. It's a guaranteed sale for them with no hassle ...
While I don't like this new development, I will drop in one data point: I bought my first Sonos devices more than 11 years ago, and over this time they all received software updates with increasing functionality. Think about it: my first Sonos players were bought in the pre-iPhone times. A lot has changed in the tech world since then.

This is something other manufacturers could learn from. It seems these days most products are launched by marketing teams: fire and forget, the moment the product is out the door, all software development ceases and it never gets updated.

I do hope they reconsider the new privacy policy, though. It's worrying.
Tight hips—and mobility improvement in general—is very likely something you can address. I'd encourage you to look into yoga or exercise programs that emphasize functional mobility. You might want to check out the Kelly Starret's Mobility WOD[0], which has a bunch of short videos that provide pointers on diagnosing and addressing mobility issues. He talks about sitting, standing and posture in particular that you might find useful.

this and the below comments just show that cars are, in general, ridiculously overpriced.

Instead of "universal basic income" - we should have "free cars for every individual" -- Look at how THAT would affect autonomous driverless cars!!!
So, even in a 1100sqft house, I consider the multiple-zone streaming to be of great utility. In fact, I almost NEVER use my Sonos setup without all 5 speakers going. Yes, you can always blast the audio in one room in order to hear it well in others, but it's quite nice to be able to listen at a comfortable volume in all rooms. It allows one person in the house to call out to another and still be heard, for example.

I have it set to wake me to the local streaming radio, so that's a nice feature, but of course it could be replicated.

I can throw my phone into a passing cement mixer and the music keeps playing in the house, and then I can open the controller on my laptop and hit "next track". In this way it's fairly analogous to the Spotify controller where I can change the music from any device in the house, but the "playing" happens on the device itself; it's not actually streamed from my phone or computer.

Also, until sometime in the past couple of years Bluetooth was godawful unusably unreliable. It's gotten REALLY good lately though, and suddenly I love it.

My understanding is that it's one of the few markets left that can move the needle. The biggest markets are health care, finance, petroleum, consumer electronics, and automotive.

PCs and phones are low-margin capital intensive businesses. Apple seems pretty good at commanding high margins in such industries.

As for why Apple doesn't license their tech, well, that's not how Apple operates, because then they lose control over the experience. ROKR and the like.
Engineering Interviewing Advice I Wish I Had Heard
Might as well call Apple an "electronics business, both small and large."
If it works with integers, it'll likely also work with 'Fixed-point' co-ordinates. A Fixed Point version is fairly trivial if you know how the integer algorithm works.
Too bad your materials engineer friend has no idea that the most hyped EV car company, Tesla, doesn't even use rare earths in its motors because they're all induction motors.

And you could of course replace the copper with the incredibly plentiful aluminum, which actually has superior conductivity per unit mass to copper. (Copper is nice because it's volumetrically more compact and is easier to make electrical connections with, but if it were seriously in danger of a shortage, none of these are anything like showstoppers to switching to aluminum.)
It seems that you either: a) haven't used a Sonos system, and/or b) have a lot of free time and don't mind resetting/rebooting your equipment when glitches happen, and/or c) don't care about multi-room synchronized playback. I won't even mention the audio quality, which on an Raspberry Pi for example, is horrible.

Sonos Just Works — some people (like me) care about that deeply. I have better things to do with my life than fiddle with audio systems. If your hobby is building these kinds of systems, then of course it makes perfect sense to roll your own. But if it isn't, I wouldn't waste my time.
Yeah, a very steady heart rate tends to be associated with higher mortality for badly injured people: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1356445/
I love H&H but feel it is worth pointing out it is more of a handbook than an introductory electronics book. In particular it doesn't really aim to teach basic circuit analysis (although it does restate a fair bit, for the benefit of those like myself whose prior instruction covered all the theory but failed to instill good intuition). Unfortunately I don't have a solid recommendation for a true beginner's resource for electronics.
So use aluminum, which has better conductivity per unit mass. And is essentially inexhaustible.

I mean does this really shock anyone? There are like no less than 20 used lots in my city alone (which is hardly a metro hub) all of which have probably at least a hundred used cars on the lot. And that's JUST the used dealership market, not even counting the new dealers, the private sellers, the rental places getting rid of cars, or anybody else I'm not thinking of.

There are actual quantifiable fuckloads of cars in the states. It's really a wonder there's enough customers to feed this industry at all, ability to pay the financing notwithstanding.
I was confused at first, because switches were mentioned in the article. But the Fates have allowed my mistake to be correct this one time, and provided a trove of education about the state of the art of network switching.

When companies focus on just one thing in a vertical, they're incredibly vulnerable. Samsung does lots of things fairly well, with some hiccups, well beyond just personal electronics and home appliances. It's diversification.

EDIT: Samsung does all sorts of things including ship-building, life insurance, construction and advertising.

For example, Apple MacBook Pros have become uncool, expensive, unrepairable and impractical... a giant FU to customers. That business is tettering on failure because they've been hypnotized on elixir of utopian, aspirational design rather than technical, environmental and practical usability. iPhone is the lion's share of
Apple's business, and they're losing ground to Android. That's a problem and most other products have plateaued and aren't anywhere near as dominant-capable or category-defining as the smartphone. That means Apple is a basically a banana republic (pun intended) unless they create or retake a category with a non-incrementalist product.

Disclaimer: I own an A1278 13" from 2013 but refuse to buy a $3000 soldered on RAM and SSD laptop that can't be transfered without proprietary service tools and whose glued-on batteries are a PITA to change. Also the low-travel, flush keyboards are terrible. Looking at Lenovo and System76 machines instead.
This is a weirdly titled report which implies it just happened. The "Apple scales back" part was already reported first by Bloomberg last year (which seems to be behind a paywall now) [1]. Bob Mansfield was brought on to refocus Project Titan on the fundamentals (being self-driving) rather that producing a car [2]. But both of these reports have the exact same hedging:

>Apple Inc. has drastically scaled back its automotive ambitions, leading to hundreds of job cuts and a new direction that, for now, no longer includes building its own car, according to people familiar with the project.

>Five people familiar with Apple’s car project, code-named “Titan,” discussed with The New York Times the missteps that led the tech giant to move — at least for now — from creating a self-driving Apple car to creating technology for a car that someone else builds.

And that's because the idea that Apple is going to be an auto parts supplier like Delphi that sells middleware to car companies is completely laughable.

There isn't actually much news in this report. The tidbits that the reporter got clearly motivated writing this article but it doesn't actually live up to its premise. In fact, PAIL seems like an expansion of Apple's efforts from what was previously reported.

> Autonomous capabilities used to be regarded as the secret sauce, and if you had it, the future of mobility was yours. This is not true.

I think you're right that when we get self-driving cars it won't be due to a single secret, but rather hundreds of years of engineering time dedicated to getting all the kinks out.

But this is still a super complicated engineering problem, and not all people/orgs will be up to the task, and will not execute on the same timescales.

I think the way this plays out will be determined by how much of a lead the first movers (probably WayMo) will have, and whether companies will cut corners to get something "good enough" out the door, and how the public will react to that.

E.g. I think it's a very different world for automakers if WayMo turns out to have a 5 year lead on them, vs a 1 year lead on them. Cruise certainly looks like they are giving them a good run for their money.
It's possible service development is happening very often, just not in the dev circles I spend time in. (web based startups)

Regarding writing interfaces for the service, that's fine too. It's just an easier way to integrate with a service. But there's a big difference between writing a service interface and a library that implements the service's functionality.

We do have plenty of open source services (e.g: Zookeeper, Redis, Kubernetes), but few product level like Stripe/Auth0. Yet there's a lot of duplicated effort in things like writing ecommerce/forum/blog/geolocation/social software. I wonder why we don't have more of these.
FTP always seemed to me to be a design that was never fully implemented. There's a hint that downloads should run in the background and in parallel while you look around the directories, but FTP clients and servers for a very long time were stubbornly single threaded.

One also has the impression that FTP was supposed to be integrated into your shell and avoid the clunky client entirely, but the design wasn't quite there to support it, so we got the worst of both worlds. A funky network protocol that ran into a lot of trouble when firewalls and NAT appeared and a primitive placeholder client that only downloads a single file at a time.

> I'm guessing that if the number of electric cars surged by 25% for a few days, it would be much less of a problem.

Some parts of the US aren't able to easily meet energy demand they can forecast when it goes up by amounts like 25%. For instance, Pepco pays to install thermostats where they can turn down/off your air conditioner[0]. Same with Dominion Energy[1]. I would be unsurprised if an influx of people of the size to cause gas shortages would also cause problems for electrical grids in many parts of the country.

My parents have a couple of Sonos devices in their home. The support is amazing. But this "Accept the new policy or we brick your shit remotely" thing needs a HARD and FAST response, this cannot be a "Well eventually the market will-" NO, FUCK THAT. If we allow manufacturers to do this sort of shit, that's the final nail in the coffin for IoT. It's already a dumpster fire in terms of software.
The last time that I looked, the Hue/Zigbee/whatever protocols were still fighting over each other to become the standard. Has that settled down?
I doubt it is $1200 a year. More than likely the full coverage insurance would be $100-$200 a month also.
Thanks. Do you know if it works with the module system - for example, if I edit function definition in a module, and then send that module definition to the REPL, would any code using that module start using the new definition?
This isn't a valid general principle. People who quit smoking late in life add extremely low-quality disabled life years.
Nvidia's Quadro GPU offerings still have 'proper' GL_LINES hardware support for CAD. I'm not sure if they still use Bresenham under the skin though. But most of the consumer GPU offerings just resort to tessellation into triangles AFAIK.

Comparison of form libraries in React
Twitter's trending tab was quitenssential in starting specific conversations on twitter.

It's what highlights particular events such award shows; and what starts site wide conversations by making a hashtag popular. The trending aspect of twitter was (and still is to some degree) what got everyone on twitter talking and engaging on the same topics.

The trending tab slowly turned into the Moments tab, and instead of just highlighting hashtags they also highlighted current events and news (the most popular ones being political at the moment)

Now instead of engaging people in popular hashtags twitter is engaging them in currents events(news), and this what dominates the majority of conversations. So I do believe the Moments tab had a lot to do with the change in tone on the platform.
I have the exact same issue. I recently moved to an adjustable desk, and writing emails is fine standing up. It's when I need to have a 2-3 hour coding session that I must sit down or I can't focus. I am wondering if this is learned behavior or if sitting down fosters creativity in some way. I'd love to see some science on it too.

I would say it's safe to assume most people here sit A LOT.

So what's the state of research regarding whether you can make up for it with vigorous activity?

Does sitting itself cause problems? Seems to be some hidden variable.
Trucks are known for being incredibly reliable and fitting almost every niche all at once. Need to haul 5 people? You can have a pickup or a sedan. Need to haul lumber? You can have a pickup or a van. Need to drive down a 2 track road once or twice? You can have a pickup or an SUV. Need to move a refrigerator? You can have a pickup... well really just a pickup. Need to haul a trailer? You need a pickup. Need to park downtown? We invented rear-view cameras for that, no need for a subcompact anymore. Need good gas milage? Why? Gas is cheap.

They last forever, are known for being inexpensive to maintain, and in the rare occasion you actually need a pickup, now you don't have to rent one. There's no situation where you need a sedan but a four-door pickup won't also work. So they hold their value very well.
There are a decent number of places that have a minimum price for using a card, and I've even seen gas stations that charge extra per gallon if you pay with credit instead of cash. I definitely agree that in the overwhelming majority of cases there isn't a difference to the consumer, and even when there is it's fairly slight.
