True. My parents actually have their apartment wired for "power groups that can run on inverter" and other power groups that will be without backup. Their power needs are substantially lower than an average American and European household. That is why I was wondering if this idea could be _scaled_ up.

I would not go around recommending anyone to buy Lead acid battery banks today. I'm in the midst of getting rid of the ones at my parents' too.

However, I found these LFP batteries where I live - NL for about 1K Euros [1] . They are 2.5KWh. Two or three of them and an inverter ought to be a good as reasonable backup for an American house dont you think?
LFP batteries dont catch fire like the Li-Ion ones tend to. No worries about oil maintenance. They come with 10 years of warranty. What is a downside to this that I am missing?

Michigan cut basically all remaining funding for higher education while I was in college. I saw double-digit percent increases every year. A few years ago I went back to look, assuming sky-high tuition rates, but they ended up only being a little bit higher than when I went.

So why did tuition get high? The state stopped subsidizing it directly.
That was a strange article: skip it and just read the discussion thread here.

I downloaded Slackware over a 2400 baud modem, so I was early on the Linux train. Now, I occasionally use my System76 laptop.

My workhorse is using VPSs with mosh or ssh and tmux. A wonderful Linux experience. Either my M1 MacBook Pro or my very nice and very inexpensive little Lenovo Chromebook suffices to reach various VPSs.

Since there is a lot of talk about macOS in this thread, I will add that I would like to get off of the Apple platform, but my digital lifestyle based on my Apple Watch (so I can avoid having to have my iPhone with me when I leave home), supplemented with two sizes of iPad Pros and an iPhone when I need a camera serves me well. I have thought of dropping all of this and going back to just using a small Android phone and a high quality Chromebook (to access those VPSs) - there just seems to be too much “Apple ceremony” in my life.
1) I believe this is app-specific? I've definitely used many applications where the menu bar just goes over the full-screened window.

2) Yeah, this one could be better. Right/alt click and "Clean Up" might help you a bit.

3) You can also right/alt click the icon in the Dock to force quit [0], but agreed that a hanging application shouldn't cause OS components to hang.

4) I'll admit I wasn't even aware of the option-click ability, so fair enough. In my experience though, the options under Scaled have almost always been the most sensible options for the display.

5) As someone else mentioned, you can turn this off. I personally also hate that they made this the default. Spaces as a whole work really well though IMO.

6) IIUC it _can_, depending on the app. I wouldn't say Windows is any better, though... it's not like Windows deletes files when you uninstall something. Cleanup is purely up to the application's implementation. Also, there's the registry. Also, if you just "delete" an application (i.e. the executable) like you would any other file, you likely just broke the application, not uninstalled it. You might've even broken the uninstall functionality.

7) Yeah, Finder does make some strong assumptions about how you're expected to use it. It doesn't completely replace using text, but try the multi-pane view. It largely accomplishes a similar navigation style involving the up function (which you can also directly achieve with Cmd+Up).

8) The default terminal (Terminal.app) is actually quite good, if barebones. It has some of the lowest text-to-update latencies out there [1]. Though admittedly, I have no idea about terminal latencies on Windows.

And you touch on probably the single-biggest issue I have with Windows: backwards (in)compatibility to a fault. If they made a better terminal, why is that not just the terminal now? I know the answer is "because people are familiar with Command Prompt", but that's kinda my point. MS rarely replaces anything. They just keep adding more versions that are available. It's great that you get the choice, but it sucks that you have to make all these choices [2] for a useable system.

I have a similar issue with Control Panel vs Settings. Edge vs IE [3].

And I'm not saying I want them to replace all the applications every year or something like that. Too bad MS does that, too. Except you also have to use the old one.

9) Totally agreed on this one. It sounds trivial but is absolutely infuriating.

10) I'm... not sure what happened here. Confusing, but sounds like it's okay?

[0]: Although honestly, this might hang as well.

[1]: https://danluu.com/term-latency/

[2]: Assuming you're even aware of the choices.

[3]: To be fair, IE is EOL, but that process has taken a LONG time. Edge and IE have both been included in Windows systems for the better part of a decade at this point.

This is not a "opening up" of anything but the source code, with a permissive license. You're free to fork and change anything you want, but it won't be upstreamed ever as the author did the open sourcing because they are stopping maintenance of the project.

So this is more of a "closing down" with the gift of leaving us with the source code. And for that Allen Webster, I thank you!
Same, though I also was due to replace my roof from 1991 and got a solar roof. It's great having a $0 electric bill every month and we've had four outages since my system went live and my house hasn't gone out at all. It'll be a few years before it pays for itself considering the price of the roof as part of the entire system - we live in a forest and power outages are very frequent so the cost for convenience is worth it.
You’re missing the point.

Alberta has many kinds of liquor stores that optimize for different things, such as price, convenience or selection, all based on market demand. Last time I checked, they had far more SKUs overall (distribution is still centralized by the government for taxation and regulation).

Your experience at the LCBO might be great, but this is coming from less efficient operation. Would the private market support a “Vintages” section in every store and unionized cashiers at $30/hr? Probably not. Why should Ontario taxpayers be effectively subsidizing the alcohol retail experience in Ontario? It’s a ridiculous proposition.

The LCBO brings in a lot of revenue, but with a monopoly on most alcohol sales this is inevitable. Every privatization study (including the Liberals’ own study which they ignored) says that privatization would have no impact on revenues, which improving almost everything for the consumer (more convenience, more selection albeit via specialized stores, etc.)

My local coffee roaster sells a "Sicilian style" 100 % Robusta espresso roast. Twice as much caffeine as Arabica, really strong stuff. I can't stand it permanently though, gives me too much anxious energy. I prefer 70/30 (Arabica/Robusta) roasts, which still have the nice Robusta flavor but a more sane amount of caffeine.

For most of my years using Linux (mint then manjaro kde, etc)I didn't have a clue whether i was using X or Wayland. Consequently if someone told me how behind the times i was because of that i would have frowned.

Given that degree holders go on to make wages much higher than those without, is it really fair that those without subsidize the education expenses of people who will go on to out earn them? Especially given how vanishingly little of it goes to actual education and instead administration and sporting programs.
I mean, yeah. But also, the expectations placed on colleges have grown exponentially. Retention staff, student life staff, counseling staff, new innovative (read: Expensive) programs, the 'experience'. These all cost money.

My experience of expectations of college in the 90's - can I drink? Do the faculty let me miss if I need to?

My experience of expectations of college now - is my child safe? Can s/he access appropriate supports to ensure his/her success? What can s/he do on campus that ensures his/her safety and security and is free? Who can s/he talk to 24 hours a day for any reason? What connections to industry do you have for him/her? Do you have co-curricular and curricular experiences ensuring that s/he learns about life skills that s/he doesn't have? Is there a gym? Are there activities available 24/7 based on his/her schedule? Is the technology in the classroom accessible for my student? Are the buildings new?

Edit: My source is my decades of working in higher education. Like it or not, the expectations placed on colleges/universities are much, much higher today. All of that costs money. Every single part of it.

My perspective on the Nx debate: As developers we can do a lot of good. Over the course of my career I helped millions of developers (through my writing on the net) and tens of thousands people use my code and programs to run things smoother or more efficiently.

I agree, I just think that the way in which LessWrong goes wrong is largely an entirely different way in which the parent depicts us as going wrong. :P

> improving rationality will lead to a lot of massively better life outcomes

IMO, to defend this, I'd argue for most people there's maybe oom of ten decisions over a lifetime that in hindsight could turn out to be really important, and if you can keep a calm head and think about it in those moments, you can potentially get a lot of benefits. Now usually there'll be lots of advice for those, and the "rational" (in the advertised, not actual, sense) answer is not always the best one, but even just stepping back, thinking about it, trying to find out how to gather evidence about it, can already possibly help out a ton.

Most people get by fine doing well enough. And it doesn't take rationality to tell you not to invest your savings in scams, so the upside is limited. But for those few times where it really matters, there are some genuinely useful tools in there, IMO.

(Though personally, I'm in it for the philosophy.)

There's also a stigma against this path.

I went to a community college for two years (it was free), and then transferred the University of Florida to finish my degree (a fine public R1 university by any standard), paying exactly $0 for my degree. I know people who followed that same path and went on to top tier law schools, medical schools, bulge bracket investment banking, etc.

Now I can look back and be grateful that I got a great education for free, but I was, and still am slightly embarrassed by saying I went to a community college.

I now live in NYC where I'm pretty sure people can do almost the same thing with the SUNY school system, and come out with an undergrad degree for like $30k (still a lot, but most folks I know paid $100k+ for undergrad degrees that are not substantially differentiated from the path I did).
The grid is sized on peak rather than average loads and at every voltage level spends many hours a day comfortably below a third of its capacity almost everywhere. In places with non-electric heating it can easily be at single digit % load factor on a cold night.

DC fast chargers are challenging for local grids but home / office based AC chargers with smart charging don't really contribute to grid loading because they only draw substantial power during non-congested periods.
There are also policies and procedures around preventing those types of conflicts of interests.

I’ve been a dev manager working with contracting companies in the private sector, I know how they work. I got free box seats to go to pro baseball and basketball games, got invited to lunch by the attractive sales person , etc. Could we get away with that in the public sector without a lot of red tape, lawyers, and public disclosures? Heck no.
> and that's usually easier to find than gasoline during a crisis. All the gasoline stations around me last week either had multi-hour lineups or were out of gas.

I'm shocked at how many people overlook this. I've had the same experience, as our "crisis" situations tend to be combined with widespread gas shortages. EVs are surprisingly convenient during most of those.

It wouldn't be fun to depend on a supercharger or other DCFC during that time, though... but maybe not significantly worse than gas even then. I've been in those gas lines.
Some excellent critiques have been provided in this thread already but I would like to offer a different perspective.

In programming terms, the switching argument (see original link) is incorrect because it does not typecheck. And it does not typecheck because variable A is used out of its scope when writing down the (5/4)*A expected value.

Indeed, variable A is tied to a specific random outcome and so it simply does not make sense to refer to it in an expected value ranging over this same outcome.

Trying to formalize the argument in a proof assistant makes the mistake clear and obvious. However, the ambiguity of the English language makes it possible for such typing errors to sneak in undetected.
I think the cultural stance in the U.S. that to progress in life/elevate oneself/stigma against forgoing college is also a large part of it.

I personally think that one policy that could have an outsized effect in solving this problem is establishing a max percentage of income that student loan repayment can be required to be for a maximum number of years (I'm pulling these numbers out of nowhere but just as an example) like 7.5% of gross income for 20 years. If the student hasn't repayed by that time using that percentage of income, the college is on the hook. Alternatively, a combination of the college and the lender (potentially switching away from government lenders).

The problem I'm hoping to solve is the insane growth rates of tuition for a wide variety of degrees that do not justify their cost. Young kids being told that college is the required pathway into a good life often are not given the commensurate instruction that the college degree should be useful in terms of earning more/securing a job. An instruction of "study whatever you find interesting!" sounds good but is IMO very poor advice. It should be modified "Study things you find interesting but remember that college is to build and refine your skills for your career after"
The extra money is going into administration. That includes salaries for non-teacher administrators and the fancy new real estate. Meanwhile they also cleverly decided to hire more part time teachers and fewer full time teachers, so they don't have to offer as much in benefits.
I have a small p.v. with lithium (BYD LiFeP) backup, just to ensure fridge/freezer/home IT and phones/light/VMC in case of outage, AC-coupled classic inverter to do more and recharge in that case.

Honestly IF Vehicle2Loads systems became spread AND an open standard I might evaluate them because EVs are NOT cheap and NOT cheaper than ICE so far, but probably they will, for artificial or natural reasons, or anyway due to lack of gasoline/gas they will be needed anyway. Surely the claim of powering for days is a bit exaggerated, more than a bit, but surely with a p.v. combined might be a way to save money in case of very unstable grids witch again is not the case so far but probably will due to various factors...

One thing I doubt is the vehicle to grid application for MANY reasons like:

- inverters too small and not quick enough to stabilize the grid

- I doubt any operator accept energy injections from countless set of moving inverters, home p.v. is normally checked BEFORE allowing to connect to the grid, vehicles move can't be checked up front

- I doubt owners want to give their energy to the grid from expensive batteries

Look at the cost of private colleges in the EU compared to the US. It's roughly what you would expect.

The difference between the EU and the US is mostly who pays for college - not how much it costs.
Depends on what you want to understand about the system.

If you're looking to understand it's properties and how it behaves I would look into something more robust like Alloy 6 [0] which has a great visualization system for inspecting models. However if you're looking for a class diagram tool then it's outside your wheelhouse.

There's also something I've played around with a bit but haven't used seriously: Moose [1]. It's basically an IDE for doing analysis of code. The trick is writing good parsers.

I like the Maybe part, everything else feels like hitting my head against a wall, every time I try to understand it.

But that's likely a me problem, I assume that for people more familiar with monads and all that jazz, it's easier to understand.
Let's not forget the bigger tool in the belt and the one that is more likely to be more fair and balanced and affordable, and that is not having forced arbitration clauses and rights waivers. Companies doing this are not doing it to do anyone a favor and to pretend otherwise is a con by the same people that want you to lose.

That's skirting uncomfortably close to discriminating based on medical history or a disability, which may be illegal depending on where the employer is located. Cancer survivors have a much higher chance of recurrence than others do of developing cancer for the first time, but most would probably balk at denying a job to someone whose cancer was in remission because there's a higher chance they'd need extended medical leave in the future.
It’s a societal good as a whole, so yes, societies should invest in them.

Example: not everyone becomes a doctor. But society needs doctors. Having affordable pre-med college programs benefits everyone, even though only doctors directly make income from the program.
