Not the OP, but we had 5 installed last May for $15k US, and they are awesome. Also a big chunk of our cost was due to the fact that two of them required a lot of exterior piping work because they were on the opposite side of the house from the base unit.

Work fantastic in the summer, quiet, work really fast, and pull humidity out as well. In the winter they are great because they allow each room to be its own temp, key for pandemic months where my wife, son, and I all like specific temps.
Agreed, it's an unfortunate namespace collision. Spintronics is a really cool area of physics, with decades of research.

Electrons have spin. Although 'classical semiconductors' exploit the electron's spin via the Fermi-Dirac distribution in transistors, the actual sign / direction of the 'spin' is ignored in everyday electronics. Making use of this available spin degree-of-freedom opens up a whole wealth of new possibilities.

Spintronics has already revolutionized certain industries (eg, GMR in magnetic hard drives), and there are further open areas of research (eg, spin as qubit basis states in quantum computers).

It's interesting to think about why that habit exists. It seems like a low barrier to entry to me. If Carmack had wanted to post to Medium or something he would've had to write and edit the whole essay and get people to come read it.

On Twitter Carmack posts a paragraph as it comes to him. Could do the whole thing at once. Could take days to complete the thread or longer. It could be as long as he wants. One tweet or one thousand. No real expectations of edits. No one would be surprised if it's only a three paragraph thought whereas going to read an essay that might feel a little brief. Nobody expects really profound or serious insight, just the thoughts on top of his head.

Readers also have the same low barrier to entry. No need to go to a separate page or app. Look at the first or first n paragraphs. Scroll by anytime.

The user experience for something like this may not be perfect on Twitter, but I think Twitter has a lot to recommend itself as the appropriate tool for sharing thoughts like this.

Business development - list of great case studies
Hi all- CEO of StackBlitz/author of this blog post here. Happy to answer any questions! (Also, thanks for posting this bpierre!)
My god, the staleness and overwhelming apathy of all people involved is just something else..
Thank you for your thoughtful reply - you’re right, there are some interesting parallels! :) Perhaps the idea is that a greater knowledge of the formal or abstracted aspects of c.s. lends a kind of long-term versatility or adaptability to candidates for large companies/an almost academic rigour in c.s. research for longer term developments... Employees may eventually move between different roles, collaboration may happen between more disparate/diverse areas of the company, or people may move up into managerial positions where they may have to cross-over/communicate many focuses/areas of business or developmental planning - therefore their thinking may eventually become more abstracted from the day-to-day practise? (as a music producer, if you understand how music is put together /psychoacoustics/some physics it certainly helps enormously with all sorts of stuff - although again, as it is an artform rather than a science of efficiency, knowing the accepted solution isn’t always an advantage I suppose - though you can always choose to ignore those rules…). If it became important to be able to document/systematise/migrate/publish a codebase then an ability to break down and communicate what you have done on a formal level would be an obvious advantage I guess?
On the other hand, a formalised system, if too rigidly adhered to, might preclude a freshness of approach or openness to different ways of doing things/hacking/combining aspects from other fields/cultures etc... Sometimes the over-specialism that you get in big organisations might kill certain kinds of innovation or the ability to ‘think outside the box’/see a bigger picture? …You could maybe make some sort of a comparison with session musicians who are (/were before the more traditional recording industry kind of died a bit of a techno-death at least! :) often expected to be very versatile, to read notation and pick things up very quickly, work in various sized ensembles/ad hoc groups etc. but were often (sometimes unfairly) criticised for being ‘bland’/sim.? …but then you might have some jazz musicians (…crossing over with many great session players…) who might have a deeper and simultaneously more intuitive understanding of music theory than some amazing classical musicians (who have the edge perhaps in immense attention to detail and consistency of performance…) …I wish I knew more about programming/computer science to be able to better discuss it! :) …I’m fascinated by the parallels between languages and music also - I guess programming languages are another variety of symbolic representation (like maths?) …I just wonder what the parallels really are between evoking emotion/promoting cold efficiency at performing a task, but I guess a lot of modern programming actually comes closer to design in a sense?(/production/library music heheh) …all primarily involve communicating with others/(the ‘other’ as machine?) and problem solving/logical resolution to a greater/lesser extent I suppose… (…even a ‘star’ has a panoply of people collected around them - producers, engineers, promoters, managers, distributors etc. and other musicians - some trained…)
Yes it is. To the point where there is actually a meme about it: https://knowyourmeme.com/memes/do-the-needful

I'm South Asian by the way, so this meme is also associated with my own culture.

Thinking that it was intentionally made broken, or deliberately broken at some point is rather presumptuous. As has been said before, don't assume maliciousness when incompetence is a better explanation.

That said, I would buy that ignoring and any fix for it is deliberate.
I'm afraid I don't recall. I feel like it probably did if it was possible, as a defense against being called a piracy tool, but I'm not sure if there was any way for a consumer CDROM to check for the wobble groove. I owned a PlayStation and official games so I only recall using those.

I've had my Hue setup change through 4 color schemes based on sunrise/sunset and time of day for a good few years now.

I'm not aware of any automagic way to achieve this result. You'll need to use all4hue, which is basically a wrapper app around the Hue API, to set up rules by hand.

Basically, you'll have a set of rules which update a variable based on the time of day. Then use this variable as a condition in every rule that turns on a light, and have another set of rules triggered by changes to this variable when a light is on. Not complicated, just tedious to program as you'll need 4 rules per light(group) for each of these categories.

But the results work with lights that stay on, lights turned on by dimmers, as well as with motion sensors. And most importantly, the entire thing runs on the bridge so no HomeKit needed. Well worth the effort IMO.

The most challenging part was meeting the goal: I really wanted to ship something after that week of working on it.

In the end, it took a few more weeks to actually ship it (as I still had to test everything and do some minor fixes afterwards), but I resisted the urge to change major parts after it was done.

I invited my co-workers to playtest the story, which helped in building a reputation on the platform (with ratings).
However, I still don't have any idea how to gain traction with something like this :).

If I recall correctly, I think this is usually explained as a thermocline effect where as deeper water gets churned up and mixed in the wake, it is a different temperature than the surrounding water outside the wake. This water has ever-so-slightly different fluid characteristics and so it presents a bit of a barrier to the usual diffusion and mixing you might expect.

There's also the potential for a very thin layer of some type of hydrophobic substance (like an oil) to be left behind that can dramatically reduce waves in that area. There's youtube videos around for that effect.

YMMV obviously. I've got a 12" cast skillet that has had literally many hundreds of deglazings done in it, never once an issue. I suspect mostly when people have a taste issue in a cast iron pan it's because they've read nonsense about never using soap on it or whatever, and haven't cleaned it properly.

I did once ruin a seasoning making a tomato sauce, which was a way to learn about acidic interactions - but that was over hours.

FWIW I had a 5 qt like that calphon but found I was always using my enamel cast one instead, so gave it away.

One thing I really like about the cast iron skillit is you can treat it roughly and use it anywhere. Mines been in fire pits, on bbq, stovetop, oven, even a bread oven. Handles temperature changes without issues (unlike enamel and some clad) is unbeatable to sear things. Doesn't care what tools you use in it. Nonstick property is pretty good (better than steel pan, worse than teflon) and will still be pretty good in 20 years.

Intrinsic angular momentum is weirder than intrinsic mass because you can take it out and put it back in - although for most particles you're not allowed to have zero. But you are allowed to take 1 from an electron to go from 1/2 to -1/2. If that is not enough, you can go back from -1/2 to 1/2 by changing your basis vectors. ;)
IMO: the IRS really needs to re-think the way crypto currency gets reported, the way it's actually used is more or less incompatible with the 8949 form and popular exchanges (coinbase in particular) generate reports that can't be directly converted to it.

I often wonder about this. I mean, just the other day there was an article[1] here about sending GDPR requests to a health non-profit in order to sequence your genes for free.

The costs of each individual piece of legislation are small, but internet legislation only ever trends in the direction of "more of it". As more small costs are added (GDPR, cookie notifications, right to be forgotten, removal of Safe Harbor etc.) these costs will start to play a factor in who can run a web service and who cannot.

Phones go into an emergency mode where they transmit the gps location. The accuracy depends on factors including length of call iirc.

I believe they can then call the carrier to ping the phone to report location. Typically that happens if the dispatcher has reason to believe there is a emergency situation and the call drops.

I think the phone will notify you of this. At least it did many years ago when I called 911 for a car accident on the highway.

I'm fascinated in learning more about how you run a web server with this - the article says "WebContainers include a virtualized TCP network stack that's mapped to your browser's ServiceWorker API" but I'd love to understand a bit more about how that works.

Since this is all done with WebAssembly are you planning on targeting other stacks such as Python? The amount of time I lose helping other people getting their Python development environments to work remains horrifying.
Well, your distro choose to include one lib that can be used with most protocols out there. They include the multi tool and many of the apps also included on the box require the tool.

If you want to use something else. You have to install it on the host. Every box comes with bash, but we still install other languages and frameworks on the host so we can run out applications with tools that make sense.

If you want a different tool, make it part of your default install.
Spanish is easier because there's just the two - an action is either discrete or not. There's some ambiguity as to which to apply in some cases, but the fact that there's just the two forms means there's basically an order of magnitude less to memorize.

But yeah, the challenge is that the prefixes/postfixes aren't uniform... if it was always po/przed/za/whatever prefix for the same use, that would be one thing, but instead it differs across verbs. Conceptually I get it, but it's just so difficult to go through the process of constructing words while speaking.

Though honestly I don't think that's the worst part - it's a ton of information, but there's a useful communicative purpose to it. What gets me is changing the endings to nouns based on the case - most of the time, doing that adds absolutely nothing from a meaning/comprehension standpoint. If I say "Cooper jest moj pies," 100% of Polish speakers are going to understand me 100% of the time, even though grammatically I'm clearly wrong. I swear it's just so my in-laws can have a good chuckle while I stumble through sentences :)

What you need to search for is "list initialization" (eg https://en.cppreference.com/w/cpp/language/list_initializati...) . I understand that it is not the obvious thing to do. If you search for c++11, it was one of the features that were introduced then. lambda expressions were also introduced in c++11 but are also found in other languages so they are easier to understand for non c++ people.

Squatypotty. I don't think it cures cancer or any of the other supposed benefits I've seen people claim, but it is more comfortable.

Black Swan in Data Security
> Things people used to take for granted.

All of that was possible mostly due to a confluence of a few major things that happened at the right time - WW2 leaving US at a competitive advantage, people having lots of kids ensuring lots of economic growth, and automation and outsourcing multiplying productivity and keeping costs low, but at a slow enough pace that people could transition to better economic opportunities and a lot of the people being left behind were masked by sheer population growth since a lot of younger people were still moving up on the ladder.

And no automation was developed to turn people over in the hospital beds or change their bedpans or clean bathrooms.

Can confirm, as someone who works in the alternative data industry this service, if widely used, will create a dataset that can easily be sold for >$1M/year to hedge funds, credit agencies, etc.
