The article is very light on the technology. (Quad Junction) GaAs cells have been produced with >40% conversion efficiency. That's more than three times the efficiency of Si or anything else in common use. The GaAs cells have thus far only been used for space-based applications. Somebody should be working on getting production costs down and deploying these things terrestrially.

I think that's where I was hung up. It makes total sense to first start with learning hiragana/katakana with whatever preferred method, then move onto something like the book you suggested. Rather than just starting with the book you suggested. And, I'm sure that point is obvious to many and why you left it out. But, as someone who only knows one language, it wasn't as obvious to me.

Thanks for the tips!
Finished "The Soul of a New Machine". It's fantastic. It mostly takes place in 1978-1979, although the machine debuted in the first half of 1980.
I was curious about the sound impact and found these two videos: 1) https://www.youtube.com/watch?v=v-sUDSwsE_w, 2) https://www.youtube.com/watch?v=zKgN2G9d0dc.

The first video has pretty sound (pardon the pun) methodology.

Findings: Unless you're within 200m of a turbine, the background ambient sounds are louder than the sound of the turbine.

Do you have evidence to the contrary?
My solar panels are actually warrantied by the manufacturer for 30 years, and there are old panels out there in the world that are 20+ years old.

"Done properly" is probably highly correlated with a high degree of control and ownership (if not in a financial sense, in a sense of ownership and responsibility), both of which are extremely ill-suited to a large company running things nation-wide.
Nitpick: Python strings are not "UTF-8"; they are abstract sequences of Unicode codepoints (and internally CPython stores UTF-32). However, UTF-8 is the default encoding for processing raw bytes received from the outside world and turning them into strings.

That said, I actually didn't realize that os.listdir() silently omits un-decodable entries, which I find mildly alarming. This behavior isn't mentioned in the docs (https://docs.python.org/3/library/os.html#os.listdir) and seems out-of-character for Python, which usually raises an exception by default if data cannot be decoded to text.

Are you sure that this is actually what happens with non-decodable filenames? Reading here (https://docs.python.org/3/glossary.html#term-filesystem-enco...) and here (https://docs.python.org/3/c-api/init_config.html#c.PyConfig....), it suggests that encoding errors should be handled by surrogate escapes by default on non-Windows systems.
There's a variation of this on the subject of distributed systems re: Erlang/BEAM VM
The observable universe isn’t particularly interesting as far as looking for life goes, heck anything outside of our immediate intra-galactic neighborhood isn’t particularly interesting because we have no chance in hell of ever visiting or communicating with systems more than a few light years away.

So how rare are true earth like planets does matter a lot.
I’m excited for the coming race to improve and miniaturise this tech. Apple has a great track record of making ML models light enough to run locally. There will come a day when photorealistic image generation can run on an iPhone.
It's the drawback but also the problem.

NPM is a giant pain point, and I suggest that Deno and a lot of other people want to move on from it.

The primary factor for Wifi performance really is congestion. My Wifi in a rural location performs way better with just the isp router than my multi access point setup in a fairly tight suburb. So far there's just no way around that except temporary fixes with new bands like with Wifi 6E.
> why is this the worst device I own?

Part of the problem is, most consumer-grade routers use CPUs that can kind of get by most of the time on passive cooling. Then when the weather is hot or your usage is above-average, it has problems.

Most people want to avoid active cooling on a router, because you've got it out in the open for line-of-sight / signal propagation purposes, and there's kind of a reliability argument for avoiding moving parts.

I'm not trying to say the only advantage of a pro setup is having fans on it, but it's definitely one of the advantages.
Not 1 in 10^21, or 1 in 10^23? Where exactly is this number coming from? You are implicitly assuming a probability that life can arise. Don't you think that number has to be informed by an actual theory of how life arises, not inferred just from your own existence?

And in fact, you can conclude nothing from your own existence. Observer selection bias.
Libel laws in the US are extremely different than those described. I believe UK ones are far more similar to it than the US ones.

The conventional view is that stack computers didn't scale because they're very demanding in memory bandwidth - every operations ends up reading 2 operands from memory and perhaps writing one result back. Which is of course exactly the wrong thing because registers got much faster than RAM. But they're also elegantly small. Are there any stack computers used today, perhaps in systems where slow speed is not a problem but ultra small size (and code size) is an advantage? I only see https://en.wikipedia.org/wiki/ZPU_(microprocessor) (2008) - 442 LUTs(!).
This was one of my biggest fears before quitting my job. It's turned out to be complete non-issue.

Took me all of 2 hours to sign up for a plan (healthcare.gov or your state's ACA marketplace). It's obviously more expensive than if my employer paid (costs me low hundreds / month) and you may not get exactly the same tier of plan, but you have plenty of options.

It's not 100% ideal, but in my experience it was not nearly as dire as people make it out to be. Your mileage will obviously vary by state, age and family size.
Huh, I donated about a year back and, while I think I did get some messages, I unsubscribed and haven't seen any since. How long ago was your donation?
Right. So, the argument "10^22 is a lot so we can't be alone" is a non sequitur.

I have less than zero sympathy for this sob story, which is exactly appropriately reciprocal to the level of respect and understanding you are granting to your family member.

There is absolutely no way to turn someone else's pile of books that you don't approve of into any kind of harm done to you. Not even through this route of death and bequest.

Sell the house for whatever it fetches wothout laying a finger on it. Then the horrible books are not your problem.

Oh, you want to extract more money from the sale? Or you want to use it yourself? That is still not his obligation. You are essentially saying you wish your parent gave you more, but trying to twist it into somehow they cost you something.

Listen to yourself!
If I were a lonely, single man, I'd probably feel as if the author was making a bit of a cruel joke at my expense when they chose a picture of a tall, fit, and handsome white dude as their idea of what a lonely and single man probably looks like.

Spend any amount of time in the communities where lonely and single men congregate and you'll see by and large they look nothing like the guy in the photo.
For the motivated, these communities still exist - but without the sermon.

Volunteer groups, sports, hobby groups, hiking meetups, dance classes, or the nearest bar. YMMV
I think a bigger difference is that books are just astoundingly cheap to produce compared to TV. That gives more freedom to take risks and try a huge number of different ideas, some of which will pay off and produce something great.

For the cost of one episode of Game of Thrones, you could publish hundreds of books. Even cheap garbage like reality TV costs enough per episode to publish several books (through a real publisher, would be even more if you count self-publishing).
The story of Lymerix is a sad one. People want vaccines to have zero side effects, zero risks, and be applicable to the entire population.

With Lymerix, the upsides of the vaccine vastly outweighed the downsides for people who live in areas with Lyme-carrying ticks, (especially those who spend significant time outdoors), but for most of the population it was pure downsides.

It's a damn shame that antivaxers were about to get it taken off the market entirely because it would have helped a lot of people.
There are replacements, you just have to seek them out.

For instance, Men’s Shed, “a dedicated, friendly and welcoming meeting place where men come together and undertake a variety of mutually agreed activities.” They often perform charitable work and if you need social or emotional support, they’ll listen and help. They fulfill the roles you feel are only available from churches.

A common technique is to tell them you're spending the money on the solar, or on the most onerous thing possible that's still allowed by HOA rules. (Don't tell them you are intentionally being onerous, just present the alternative.)

For instance, thanks to court rulings that allow the FCC or overrule HOAs, you could put a giant hot pink DIY installed satellite dish on your roof.

Give them an olive branch, so they can pretend they won. For instance, make it clear you will exceed installation guidelines for the mounts, get the work inspected, and that your homeowners insurance covers the install.
Ouch. I use Hetzner and OVH but after this I guess no more Hetzner for me. I already had an unpleasant encounter described below. Do not want to give Hetzner a chance to screw me with this kind of asshole attitude.

Previous experience: I already had one of our videos suspended for "copyright violation" (this was on media hosting site) despite the fact that I fucken made this video myself. Some company had stolen it claimed as their own and submitted hash. Since mine has the same hash ( duh! ) access to my video was blocked resulting to download complaints from customers who purchased it. I sent numerous complaints with the results that amounted to roughly "fuck you". I've given up but suddenly out of blue after 2 month I received the apology from some C-level of theirs telling me that they were in error and access to my video was restored.
The problem is that plenty of poorly-coded signup forms reject the plus character as invalid within an email address.

I think the DMCA protects them against liability for simply staying within the DMCA safe harbor. But if the claim itself was malicious, the DMCA does allow you to sue the person who made the claim.
So, looking at it from a project management point of view: it's working. Insert as many asterisks, fear quotes and footnotes on that first sentence as you feel is appropriate, but, generally, it is, for better or worse. I think, like other working software out there, it's not degrading, so the only impetus for refactor is changing external conditions (expectations, medium, usage, etc.). This has been happening gradually. On the other hand, my understanding is that direct stakeholders (miners) are extremely resistant to change, unless it solves an existential problem in the medium, as they don't want to mess with their setup they have. I would not call these ideal conditions to see a refactor of code take place, as that holds risk and offers no benefit to stakeholders in their view.

The rest of the world seems to agree, as people who wanted big change made other coins that are faster, more private, etc., and other people who wanted Bitcoin to be less shitty devised things like the lightning network, which is a protocol on top of it.
> Am I way out of line here, or are the labor prices reasonable?

Are there more than a handful of independent sellers to choose from? If there are, and you are not willing to do the work yourself, then I would say the prices are reasonable.
Meanwhile I do basically the same thing (different provider)

I could (and should) shame at least a dozen decently well-known organizations, just ridiculously low on my list to go digging again.

Surely partly due to filters, but also our activities/circles - and the control over their data. A lot of compromises lead to leaked lists of addresses to both spam and target for gaining access

How's Las Cruces?

We were looking at possibly relocating to a friendlier state than Texas if gay marriage were to be overturned. Thankfully, that's looking less likely, but it's still on the back of my mind a bit. We have some family in El Paso, so that would be convenient.

Main consideration would be quality of public schools. Some semblance of a social life for folks in their early 30s/parents would be nice but we could deal with that being not as great with El Paso close by. Availability of decent groceries, especially for cooking Mexican dishes, and fast internet would be pluses as well. I imagine the real estate market there is quite cheap. We'd love the climate if it's the same as El Paso.
I just did a bit of research into this here https://news.ycombinator.com/item?id=32472087

You can actually reconfigure Python to throw an error instead of using a surrogate escape, but only (I think) changing something at compile time: https://docs.python.org/3/library/sys.html#sys.getfilesystem...
Is deno successful? I (in my limited world) don't know anybody using it and don't see it mentioned in job descriptions etc.

And to comparing to other languages: It's not like "ok, projects became to big we need better package management" or something, but to me reads more like "there's too little deno stuff and migration prevents people from going here, so let's try to embrace the other runtime's stuff so maybe more people can use our runtime without having to start from scratch"
Jetbrains IDEs have a plugin called `Shell Script` that provides code assistance and warnings. It's also compatible with shellcheck too.
This is not a criticism of Blitz which looks fine. From what I can see, it is better than fine.

However, this reminds me of the early Rails (or even Rails 4.0) demos that I saw where they build a blog in 5 minutes.

Here is the thing: The fastest way to get a skeletal app running -- even if it is written in C -- is to

> git clone already_written_archetype.lang

And then you can modify it.

So you can put that archetype into the framework. So I always wonder if the right example is not build a blog or to-do-list or twitter clone. The right example might be:

take a blog and change it into a twitter clone

Because you can always download the archetype if you need to but the framework should demonstrate how nimble it is. (Again, I don't claim Blitz is not nimble and I would have to play with it to know.)
That's a really hard question to answer. I'm getting towards the end of a to-studs bathroom remodel, and it's taking an amazing amount of time, probably 300 hours. But, if I hired it all out it could easily have been $25K to be done to a similar standard. I'll have around $5K in materials in when I'm done. But I also know that if I hired it all out, there are a number of things I've done that wouldn't have been done, for example I ran 500 feet of 12-2 romex to replace current several current 12-2 aluminum runs, switched our bedrooms over to AFCI, ran several spare 12-2 runs for future renovation, removed a totally not to code wiring situation that was a fire waiting to happen...

And on top of it, I gain experience and get to know my house inside out... But on the other hand, I haven't had a spare weekend for 6 months.

So how do you value that on a per hour basis?
At this point i feel so much guilt for driving (on weekends now and then) a guzzler that i’d rather throw it to the bin and never look back. Either way i am never again driving an ice car.

>I'm just wondering how bad a typical solar install is, that what I consider "sane and reasonable wiring I can visually trace without heroics" is worth mentioning specifically.

Any neanderthal who's had the code beat into them can do the wiring just fine. I would be far more worried about "professionals" drilling holes in dumb shit to save 5min or mounting components in dumb places for convenience than I would be about them doing a bad job at connecting it all together with copper.
40% is not, in fact, 3x, or even 2x, current best efficiency of Si or CdTe panels.

And, the important efficiency measure is W/$, where GaAs trails well back. Perovskites may exceed 40% conversion efficiency, and also have good prospects to offer much better W/$. Their endurance has grown encouragingly quickly.
I don't have an opinion on that product, but no smoke alarm is "hushable" due to state laws, as far as I know.
In case the theoretical point of containment corrosion doesn't quite deliver, consider the practical one [1] from Brunsbüttel in Germany. The solution? If one rusts through, just put it into a bigger one!

Why are you grouping everything electrical under labor costs, if it includes things like expensive copper wiring and a $4500 electric panel?
You might want to check your state laws, too. DIY for mounting the panels is one thing, but tying into the grid is another, because you need to set up backfeed correctly otherwise you're putting linemen at risk. If you already know how to do all of this correctly, then maybe you could just get your electrician license ;-)
I use an alternate spam filter process. I use a "+" sign in my gmail address. So I would subscribe to a promotion/giveaway with username+company@gmail.com. This is a great way to catch which promotion/company sells your email address to unwanted companies.

Caveat, sometimes an unsubscribe website can't handle the "+" symbol in an email and you'll continue to get spam. So, just add a filter for that "TO" email to forward to the spam/trash folder.
Congrats. I'm seeing a lot more friends who have done what you have done How did you find clients?
I think both you and the parent probably hit on the main points. I think it was something of a fad and after the novelty wore off, some of the limitations became more apparent over time. And, while I played a few games quite a bit (Wii Sports, a couple of different tennis games, snowboarding) over probably about a year, the only other game I played through was World of Goo and it would probably have been just as good on my PC. Certainly after the original sports games, nothing new came along from either Nintendo or a third party that really grabbed my attention.

I set it back up at one point but it never grabbed me again.
What are some examples of the more expensive type of registrar? name.com?
One neglected issue in this article is US tariffs on high-efficiency, long-lasting monocrystalline silicon PV panels (only manufactured in China at present, with some subsidiary assemblers in other Asian countries). China developed a low-cost route to single-crystal production technology and that hit the global market around 2015. The USA has no comparable manufacturing technology or capacity, not even close. For example, see this article from 2018:

https://www.pv-magazine.com/magazine-archive/chinas-monocrys...

See also:

> "The new tariff, which went into effect on February 7, 2018, will likely increase home installation prices of solar panels by $500-$1000 for the typical household. Due to the increased costs of obtaining both solar panels and the technology necessary to create solar panels, the amount of solar installations in the US is expected to decrease by 11% by 2022; some experts in the industry predict that installations will decrease by more than 25%. This major hit to a growing industry could result in a decrease in American jobs; layoffs at solar panel manufacturing plants are expected."

Hmm. The issues that come to mind are annoying pairing (Arch -- probably my fault, too manual) and some weird random disconnects on Ubuntu, but that might be some power-saving issue specific to my chip. So maybe I just got unlucky random outcomes.
