Correct me if I'm wrong, and I quite possible could be, but from a quick Google search, I'm seeing numbers of anywhere 200Wh/mile to 350Wh/mile for a Tesla. If we're generous and assume only 200Wh/mile, then 40 miles of range translates to an energy consumption of 8,000Wh.

A 100 watt solar panel, producing the full 100 watts, would take 80 hours of perfect sunlight to produce enough power for an extra 40 miles of range.

Assuming best case (unrealistic) conditions, if you get 8 hours of perfect sunlight in day, and your solar panels produce 100% of their rating for all 8 hours, it would take 1000 Watts worth of solar panels to produce that extra 40 miles of distance over 8 hours. It seems kind of unrealistic to fit 1000 Watts of solar on top of a car. And that's an absolute minimum, under best case conditions.

If you had, say, maybe a more realistic 300 watts worth of panels on top, and they got 4 hours of full sunglight, you'd be producing an extra ((300W * 4h) / 200Wh/mile) = 6 miles. And that's still assuming best case condition for power consumption per mile.

[Edit] - And like the other commenter stated, those few extra miles get cut down when you consider the weight of hundreds of watts of solar panels added onto the vehicle.
I just translated the German term Erwartungswert wrong. The English term seems to be “expected value”, and it’s basic enough that you learn it in high school.
Mine is similar to CarVac, but I also rough out some Use Cases, and I rarely do GUI as I hate doing GUIs. When thinking about the design if there is a part I think is tricky I might pseudo code it. If it keeps me from sleeping I will actually write it out.
I just find that Americans have little understanding on how things run in Europe. But same goes the other way around.

If you want to earn a lot - you go contracting in Europe.
I used to save about half of my income when contracting 6 years ago in London. My rate was 470 GBP for 220 days out of the year. My expenses were taxes and 700GBP in rent. I saved 60k after tax... and I used to fly business class to Thailand, NYC and Mexico.

My income is technically higher, but expenses are through the roof. You sneeze here and it's $20 gone.
McNugget I think.
Cheap for the economy, not so cheap for the environment.

These kind of articles rarely calculate the price to dispose old solar panels.

Our country recently found that current methods for disposing solar panels pose a grave danger to the environment and imposed strict regulations for it. As a result the price for disposal quadrupled. Because consumers of the solar panel, which are mostly individuals, can't afford those prices, the government is preparing for a law that charges manufactures up front for the price of disposal.

It is assumed that solar will be more expensive than natural gas after the changes.

You have no way to know that “our experience of life is always changing.”

It doesn’t always get better. Sometimes it keeps getting worse! Sometimes it stays equally awful!

What’s true for you and the people you’ve heard talk about it isn’t necessarily true for everyone. Maybe the people who died on the bridge would’ve hated surviving?

Profitable for the first guy. Not profitable for anyone after enough people try to get a piece of that action. And maybe not profitable for anyone ever if the power company themselves installs enough storage capacity.
Why are you comparing your scheme to a defunct system, then? The cities in Europe I’ve lived in, and the cities in Asia I’ve visited, haven’t had that problem at all.

Thank you for commenting.

I was quite beautiful when I was younger. I was also molested and raped and told it was my fault for being too beautiful to resist.

I considered becoming a model at one time.

I also was one of the top students of my graduating class, won a National Merit Scholarship to one of the two most prestigious universities in my home state and had other academic accolades.

My beauty seems to have been more downside than up. It is actively problematic for trying to pursue a serious career that doesn't in some way trade on your sexuality.

Most very successful female singers, actors, etc are beautiful and sexy. The top paid ones don't hesitate to pose nude and trade on their sexuality.

Men don't have to trade on their sexuality to get to the top of their field and men have many fields outside of entertainment open to them where they can make good money.

In fact, it boils down to this: being successful in a career is what makes a man desirable. But a woman is asked to choose to either be serious or be desirable.

I have found my looks and gender to actively be a problem in getting good constructive feedback. I suspect this dynamic is part of why Theranos was valued at $10 billion before being uncovered as a fraud: It was led by a pretty young woman.

I suspect Theranos would have deflated as the hot air balloon it was well before it hit $10 billion in valuation if it had been led by a man.

I have zero interest in using my looks, sexuality or femininity to open doors for me because I have no desire to follow in the foot steps of Theranos. That company has already done plenty of harm to the status and perception of women.
Last I checked it cost more than a $100,000 (on average, in the US) to raise a human to the point where they have sufficient control over their behavior and body that they could be trusted to safely drive a several ton vehicle.

Humans have the biology for visual systems, and constant training, and it still takes us almost a decade to fully process distance properly. (This is why children will run in front of moving vehicles--they can't actually tell how far away they vehicles are.)
You know a cool thing you can do to help fixed point interop between operations in a complex system where you absolutely don't want to accidentally overflow anywhere? You can tack on some bits to the number to control an overall scale of the fixed point number. Let's call it an exponent ;)
> the better idea is to segment out what exactly you want to use it for and use a specific file format for it

What I want is basically an entirely static (no javascript, forms, media elements, etc) copy of a web page, with a logical deterministic rendering, and a fixed page size (no reflowing). Basically, if you took a web page and printed in color on pieces of paper, the HTML + CSS that describes the stuff shown on the piece of paper is what I want a "portable document format" to be. (Along with a set of rules that specify exactly how that code should be rendered.)

What I want in the spec is basically dictated by that:

* vector graphics: yes, SVG is supported in all major browsers. https://developer.mozilla.org/en-US/docs/Web/SVG

* bitmap support: yes, let's start with PNG, JPEG, etc, and updates to the spec can introduce new formats

* color management: yes, should be required by the spec

* unicode: yes, we can probably be UTF-8 only at this point?

* font rendering: deterministic; make it part of the spec. Fonts should be embeddable in the document. Ideally the font rendering for the end users should be as high quality as possible (this is quietly one of the things PDFs are already doing very well).

* glyphs / ligatures: should look exactly as they are determined by the author of the document. The spec should allow for the full use of the capabilities of an OTF font.

I think this probably covers the stuff 95% of people want from 95% of their PDFs, and it's vastly simpler than what's currently in the spec.

Honestly, PDF/A comes pretty darn close to getting there. The most recent version allows embedding arbitrary files, however, and there's lots of annoying cruft from the PDF format. (Renderers have to support displaying embedded XML forms, for example.)

In this era of global communication, I think the Protestant mores may be less important, relatively, than they once were.

Edit: US based companies appear to me to at least as concerned with new markets than existing markers. In some cases, China and the middle east are the regions which motivate 'puritanical' discretion, not the US.
It’s fine, so long as you want to store random assortments of random documents, in small collections, and you can get all that into a single machine.

As soon as you need to scale it up by sharding or replicating, you’re fucked.

I guess previous posters "If you can't teach it, then you don't understand something perfectly" can be replaced with "Process of teaching someone will make you notice all the holes in your own understanding"

Or even without replacement. Teaching someone doesn't imply a successful result.
A documentary focused on the people trying to stop suicide is going to be very anti-suicide.

I'm working on starting a Wireless ISP in rural Portugal:

https://gardunha.net

It's a nice mix of both online and offline work. Also, the community around here is mostly made up of various combinations of farmers, hippies, retirees, and permaculture folks. Everyone wants a decent internet connection, but no one really has the skills to do much about it. I've lived here a year now, so thought I'd give it a go.

It's a windy road. Actually, it all started out because I wanted to get fast internet for myself on my farm. Then I thought, "Hey, why not start a business?" Feature creep at its best.
I agree for Shopify a rewrite would not make sense.

But I think writing new features, or rewriting some critical paths of the codebase in a new language could make sense.

It's atleast a valid question.

They are clearly already spending a lot of resources optimizing Ruby code to match their demands.

My question is at what point does continuing with Ruby become trying to force a round peg into a square hole?
Could it not be built into the roof directly! This is a great idea as presumably people who don’t use their car a lot need not leave it charging permanently and if you run out of battery you can just wait (if it’s sunny enough).

You think it's bad, I've still got "Telephone" stuck in my head every time I hear about the Telegram blockchain. But you know what they say: a pain shared is a pain doubled!

The software is just another DPOS blockchain with smart contracts - it doesn't do anything much better than the multiple other such pseudo-decentralised blockchains. The only point was to support a token offering.

The problem with a lot of that is "low effort" versus "high effort" content.

I've seen a lot of great subs and communities take a pretty dramatic shift when the influx of new users is too great. It's basically the "eternal september" problem -- when the new users start to overwhelm the old users, they're no longer able to be effectively inducted into the community and the community makes a hard shift, usually to lower effort content as the quicker it can be consumed, the quicker it can be upvoted or otherwise appreciated (and usually it's quicker and more accessible to create than truly valuable content).

Or more straightforward--any community which experiences significant growth will eventually devolve into memes.

The one mitigating factor can be moderation (e.g., Hacker News). But if the mods can be replaced as well, then there's nothing holding it back.
I built Obsidian (https://obsidian.md/), a local Markdown file based knowledge base app. It supports internal linking and graph view, and recently added multi-pane capabilities too. It's looking more and more like an IDE for your knowledge by the day, and it's quite amazing at that.

I also wanted Obsidian to be very extensible, and the private beta community has already started extending it and it's so cool: https://github.com/kmaasrud/awesome-obsidian

To me it looks like it will never be a meaningful solution, due simply to physics.
Why is that? I was under the impression that gas versus coal just changes the fuel that is burnt.
Depending on where you are, that's pretty close to what's happened. Right now (4pm), the California ISO is generating 73% from renewables+hydro, 7% nuclear, and the balance gas. Naturally, the night replaces solar with gas.
This is largely how California has reduced electricity emissions to their current levels.

So are you saying that we should abandon renewables, and stick with fossil fuels until a truly green energy technology is invented, sometime in the future?

And if that is not what you are saying, then what exactly do you think we should be doing today?

How about it making it theme-able?, with the default theme something that everyone will most likely change because it's so bad (i.e. bright neon green). One of the themes could be a WL match. If you wanted to go nuts have the themes as a separate github opensource repo (not connected to the project) which the app pulls in.

Or just smarter appliances. Plenty of opportunities for thermal banking/battery banking.

Most of my loads, on average, don't need to run that exact second.

I don't mind if my hot water tank super-heats water in the middle of the day for the rest of the day. If electricity is really cheap, my freezer can jump into overdrive.

I don't need my clothes to dry in the next hour, just over the next 8.

I don't care if my fridge/freezer takes a break while I run the microwave or pre-heat the oven.

I don't care if my car charges ASAP as soon as I park, as long as it's charged by 8AM. And let it run as a grid-power bank for a fee.

Then you could have A/C systems that make ice or compress refrigerant in a tank.
Also V8 underpins Node, which has many more legitimate use-cases for that much memory.

That said I think we need some sort of user-facing permissions constraints for memory usage and/or webassembly execution. I fear that in practice this new capacity will mostly get used by unscrupulous crypto-miners.
If you want the luxury of scale problems down the road you do RoR until you lock down that first couple billion dollars of valuation. Just ask Stripe, Github, AirBnB, Gusto, Shopify, Coinbase, Dropbox, Twitter, Door Dash etc. Then you can have the "problem" of picking the wrong language. Massive survivorship bias in the panning of Ruby/RoR IMO...

Also the Ruby/RoR community and culture is better than most other languages/framework. I think culture is a totally valid performance reason to pick a language. Sure there are faster languages and there are jerks everywhere but on average it seems RoR devs are on average nicer and more collaborative people relative to peers.

There is a just a mindset for wanting to write in a language optimized for developer happiness that dovetails with wanting to be happy and work happily with other people. Ya sure those C++ guys can write more performant code but I know who I want to work next to 8 hrs a day. And who I will be more productive working with.

Also I don't think there are plenty of languages that are Ruby/RoR peers. Django doesn't come close. JS ecosystem is a dumpster fire. Some functional and JVM languages maybe but they often come with a corporate culture that kills their benefits. Kotlin would be my bet I guess?

Also if scale is your issue and rails isn't cutting it then you need to go to a proven language with a proven and hirable developer base. That rules out a lot of new and promising languages. Sure they might be just as productive languages but they are resource constrained at the people level. It is really hard to hire Elixir/Phoenix devs etc. You need a talent pool of thousands. Also you need to KNOW the language will be there with a community in 10 years and that it has a history of evolving without screwing over the community. I guess Twitter going to Scala would be an example of this, from my understanding it doesn't solve all their problems.

Total aside: plenty of language need massive tuning to work at scale but it seems like Ruby is unfairly singled out if someone does "exotic" tuning of it but if someone tunes a JVM language or invent their own it is supported.
I don't think many people on this board comprehend that there exist professionals at most companies whose sole responsibility is to identify, recruit, and onboard new employees.

Or that most companies are willing to hire people who aren't perfect candidates because a fair amount of internal training is expected. Hiring only unicorn candidates who already have the perfect qualifications and don't need any training/onboarding is a peculiarly Silicon Valley phenomenon.
I think you just don't like that your hairshirt and woe philosophy is not popular or necessary.

Microsoft makes a ton of money selling the exact opposite.

There is an edition of Windows called "POSReady" that is used in Point of Sale, ATMs, and other embedded devices. Microsoft guarentees drivers won't change, no patches will be issued, and almost all security controls are disabled. If you build on top of it, the underlying OS will never change.
I have many blogs.

I don't think my remarks are in any way off topic.

I choose to use myself as the example because then I'm not doxxing other people, in essence. I can say as much or as little as I feel comfortable saying about myself.

You're ability to participate here is facilitated by the nearly 11 years I have spent here. I did a lot of laying of the groundwork to make it possible for women to open their mouths here more readily and participation by women is up.

Maybe use that ability that I helped make possible to do something other than piss all over me.

(Edit: For that matter, I have reason to believe my participation here also has made it easier for the LGBTQ crowd to participate more openly in part because I am not straight, though I don't comment very often on that fact.)

1. Yes — it’s their choice just like any elective medical procedure. If there’s enough demand for a legal service, somebody will offer it.

2. No — I don’t need to have a chronic illness to know that I hate my life and would rather die painlessly. Mental illness is not always treatable. If someone wants to die that opportunity should be available to them.

3. Don’t understand your question here.

4. No. Killing yourself usually leaves somebody else a mess to clean up, both literally and mentally. Plus I’m not skilled at killing myself and there’s a good chance I would fuck it up. If it’s a legal service, somebody will take my money to do it and that option should be available.
That just dumping old solar panels into the landfill will cause Cu, Pb, As, Cr to spread into the ground effectively contaminating it. The government is trying to ban dumping it and trying to impose a responsibility to manufacturers to properly recycle and decontaminate it, which will cost about 4~5 times more than dumping.
