Of course, but the energy input of the battery consists of the electricity that was charged at the power socket plus the kinetic energy that is captured by regenerative braking.

First, you accelerate - this converts electricity from the battery into kinetic energy. Then, you brake - this converts kinetic energy to electricity and stores it in the battery. You can then convert it back into kinetic energy the next time you accelerate. Effectively you get to spend 22 out of 100Wh that you put in at the power socket twice. You can get 122Wh from the output of the battery before it's empty because it has a second input.

I find the confusing thing about this argument is that the kinetic energy that is eventually recuperated due to braking is counted as productive work. So this 87-91% ratio is how much kinetic energy was produced in total ("Energy to Wheels") - whether it eventually turned out to be useless due to braking or not - divided by the electricity charged at the power socket.

In contrast, an ICE car can't recuperate at all for lack of technology to synthesize gasoline, so the kinetic energy is converted to waste heat energy.

What would violate the principles of physics is if the captured energy were larger than the electricity that was originally put in (assuming no other inputs like a downward slope) - that would be a perpetual motion machine. At 100% recuperation, the car could never move.
Why do you think someone would bother to steal your code? Is this that revolutionary or are you delusional?
Except that we know entanglement is non-local: this suggests that non-locality rather than non-determinism is the correct resolution to Bell’s inequalities.

Non-determinism is an extraneous assumption if we’re forced to accept non-locality for other reasons.

Edit:

I’ve hit my posting cap, so replying in edit —

If we know particles are entangled and subject to non-local effects, we’re already concluding that there’s a hidden non-local variable: the sum of all entanglements we don’t know about.

You can model that as a randomness distribution for calculations, but that doesn’t make the universe non-deterministic.

Edit 2:

I think where we diverge is in the belief you’re measuring “nothing” and so it’s strange you’re getting slightly varying results. I’ll have to think about that aspect some more.

I’ll leave off here with a big thanks for giving such detailed replies!

> Klarna’s “Super App” was an area getting lots of investment in 2021. This investment was a step away from the core offering of the handling of payments. The vision of this app was to create an experience where people could do all their shopping within a Klarna super-app.

However, this super app never launched as planned. Internally, confusion arose when it emerged the super app would use scraped data from customers who were already partners of Klarna. The super app efforts are still progressing slower than originally planned, and some employees think the company is spending too much on this area for too little return.

A vCard parser and validator. The original Python code was clunky, and I've tried to reboot it in both Java and Rust. In the end I've always fallen back to Python, spent a few days bringing things back up to a half-decent state, and then table-flipping at the packaging stage. It will probably never get to a good state, but it's useful for me.
> However, I wonder if a better approach would be to offer this PaaS but also lower level baselines that make using AWS easier and more secure so it’s not all or nothing to take advantage of their services.

That's what I was working on for a little sub-agency.

You have to start somewhere, with a menu of cloud services that you'll offer to anyone who wants to deploy their app for the federal government to use. You can make that menu selection larger or smaller depending on what services are on the approved list.

Platform One, for example, is PaaS built around Kubernetes deployments. Mine was built using a much larger approved list of services (Kubernetes, Fargate, and so on) that an entity could select to deploy their app/service.

If anyone, you would be the moron. If Norvegian electricity is more expensive because of Germany, then because Norway is selling it at that higher price. If Norway wouldn't sell it, there would be no money flowing from Germany to Norway. Where the money goes? Well ask your fellow Norvegians and don't blame your countries customers.

P.S.: if anyone, France is guilty of the current high electricity price in Europe. They are failing behind producing enough electricity for local consumption and consequently drive the sport market price up.

I entertained the idea to make and sell the hardware myself. But in the end I learned that's it's not something I'm interested to get into. What I really like is working on the software.

In the end this pivoted into a more community driven project where multiple makers are selling various variations of the HW and giving me a cut of their profit to support the SW development.

Recently I even got a Chinese company, notorious for selling "clone" of OSHW projects, to support the SW development as well via GitHub sponsor.

I'm not sure if anything has or will happen with this, but this seemed like an interesting symbolic extension of neural nets: https://syncedreview.com/2020/11/19/facebook-building-automa...

At least my take on it is: what if you simulate a domain (physics being the most tractable) then can you train using differentials of the model itself and not just differentiating the internal neuron estimators?

Lots of open questions... like what's the driving force that asks for an effect that calls for differentiating the model? We kind of expect the training process to just recreate everything internally.

Now it has me thinking about "coprocessors"... a lot of the domain-specific math is given to the NN as input features, but what if the NN could select inputs to those algorithm? That would give the NN the ability to speculate. Of course you'd need to also differentiate those algorithms.

Now that I'm thinking about it, I guess this is just another activation function, just one that is domain-specific. Are there approaches that use eclectic activation functions? Like in each layer 1-10 is one activation function, 11-20 is another, and then you finish off with tanh or relu or some other genetic activation function.

Emacs is popular. I like vim, but people are also using VS Code. https://lispcookbook.github.io/cl-cookbook/editor-support.ht... and other pages on the wiki may help you. https://github.com/CodyReichert/awesome-cl#community has a list of community spots if you want to seek out other opinions.

The SBCL implementation is very good, consider getting a binary directly from their site if your distro's version is out of date http://www.sbcl.org/

I disagree with a sibling comment that this book expects you to be comfortable with Lisp; the first chapter is literally an introduction, and the next two chapters cover most of the basics a working programmer should expect to cover quickly with chapter 3 being a handy reference to look back on for a lot of things. If you're new to programming or find the intro too fast, sure, look at other resources, but it's not too bad to just dive in. The main supplement is to figure out, with your editor of choice, how to send blocks of Lisp code to the Lisp prompt so that you can type and edit with an editor and not have to do everything directly on the prompt line.

Blub is an attitude, and people confuse a tool useful for fighting that attitude for absence of the attitude itself.

Lisp's power is that you can always use reasonably efficiently it to write the blub you need to solve the problem. But if you already have a suitable enough blub at hand, that's not really helpful.

The neutrons released by the fusion reaction can be captured by the atomic nuclei of other materials it encounters, in a sense fusion. This induces radioactivity in those materials, called neutron activation, but won't create a run-away reaction. Nuclear fission reactors also produce neutron radiation that behaves in the same way, except in nuclear fission fuel it does create a chain reaction.

> Sounds a bit like a nuclear reactor.

They are nuclear reactors. Nuclear fusion reactors, rather than nuclear fission reactors.

it very well may be in industry wide problem, but Tesla seems to be front-and-center of this problem.

Great you sent me a link about paying $8 to use your remote start.

why are there so many stories like this one:

"Right off of the top, it’s no secret that Tesla will disable features before reselling a used vehicle that’s traded into it. While that might sound shady it’s within their right to do so. What isn’t so common is the situation that led to one owner walking out of his house one day to find his Model S with 80 miles less range than just a few minutes previous."

Is this not "john Deere" type activities?

how about this: "Tesla’s $16,000 Quote for a $700 Fix Is Why Right to Repair Matters"

or this: Hundreds of Tesla drivers were locked out of their cars at the start of the weekend after the manufacturer’s mobile app suffered an outage – and dozens voiced their complaints on social media.

If the software doesn't work, neither does your car, is this not things "John Deere" is known for?

Even if their founders deride communism in spirit, almost every corporation is run pretty much exactly like Soviet communism was. Even the aesthetics are sometimes similar.

I'm not saying that these things are equivalent -- they obviously operate at different levels of society. But the similarities are striking which makes some of the criticism a tad hollow.

I'm 55, I have no problem learning something new if I am interested in it, and I think that is the key.

Some people just seem to lose interest in new things as they get older, sometimes as young as 40, I have seen. Once you lose interest in new things it's very hard to learn new things.

For some people it seems there is a certain comfort and security in only doing things you know, for others it is the opposite - same same is boring and new things are interesting.

I see collegues, some more than a decade younger than me, setting in their ways, and the biggest predictor I notice is music tastes. Once they start closing off and lacking interest in any new music, that's the beginning of the stopping of growing (and starting of dying) in general. Make a point to listen to new music.

Also, children keep you young, if you have them take some time to listen to their music and talk to them about the trends in their world and keep familiar with their jargon. That will also stop you getting old before your time.

> The culture of “we are awesome” has dominated most internal communications for the last couple of years, including in 2022. We all believed that we were awesome and would continue growing and winning.

This is the big thing that drives me nuts.

I don't know if it's a fragility of ego thing or what the cause may be, but it results in a corporate inability to critically self-evaluate at the highest levels. If you can't say where your weak areas are, you're not improving.

One of the experiences that untreated ADHD blessed me with was routinely failing classes. That repeated exposure to undeniable failure (and the consequences of it) really helped me accept that failure is the default. If you're not constantly fighting against failure, you're failing. You can't pretend that something didn't work out, or stop thinking about it because it hurts.

The self congratulatory back-patting (even if it's just "everything is fine, we're doing great") is treating success like an achievement. Success requires vigilance. Excellence is not an achievement, it's an activity.

We need more leaders that talk about the things we could be doing better, and doing so inspirationally, not derogatorily. It's ok that you're not the best at something. Very few are. That doesn't mean you can't or shouldn't do better.

Try internalizing that if you're not constantly struggling to do better, you're not living up to your potential.

> USD is safe and sound as long as USA and USG are.

I agree. People living in USA or Eurozone may not see the need for BTC since they have good stable governments with well-managed currencies[1]. People outside of those pockets, however, need some option to escape from their governments' corruption and tyranny. BTC is a neutral, and hence better, option. Because if your country falls out of favor of USG, your savings just became a collateral damage when USG imposes sanctions n all.

[1] this sentence might come as a shock to some since news media constantly paints apocalyptic picture. But US and Eurozone is a really good area of the world to live in.

I'll be driving across the American West this week, and it made me wonder -- is there anything like flightradar24, for but trains? (I searched this in Google and got a 5 year old reddit post that only had resources for the UK).

It would be neat, if I found a photogenic location, to be able to see if a train was coming along soon.
If you know that answering the question will make people lose interest then that suggests they will lose interest even after reading the docs as well.
There are two main reasons why the theory is “incomplete”

1> human perception is not often considered; in many ways humans are like dogs trying to see in full color depth. Humans are “colorblind” to types of information.

2> structure of the flow is not often considered: the assumption is a flow through some X-dimensional space: what if this flow is defined according to a chaotic map: not just a fractal but a subset of other rules which create chaotic flows across multiple dimensions in time which collapse /retroactively/ along a chaotic Riemann geometry

I think there is quite a difference though in the lifecycle between glass & aluminium. Glass can work when it's local and smaller producers, but on large scale production and national distribution it can introduce several problems.

Glass is competitively heavy and thick so adds to transport requirements. It also can't [generally] be made on site, unlike cans which are generally formed in the food factory for larger scale producers.

There is also breakages to consider. Modern 'bottling' plants move at an incredible speed and where glass is fragile any chips or breakages can shut the line down for cleaning; shards of glass are nasty to get in your drink. There is also transport, rough handling is much more likely to break glass bottles than burst cans, the cleanup is also easier with cans, and as glass weighs more it also adds to handling costs. This also applies to recycling, a bottle takes up much more space in your recycling bin than a bottle does.

Personally I too prefer glass, but once you get beyond extremely local small scale production the considerations change dramatically.

Right? If they are even somewhat productive, there should be enormous output created by them.
There's a reason why recruiters at Spotify jokingly referred to Klarna as "our relocation agency". Klarna would relocate folks to Stockholm who'd then leave within 6 months to a year once they realised the shitshow they signed up for.

This was in 2015. They didn't value people back then or care to treat folks with the tiniest amount of decency. Seems not much has changed.

Compared to all the effort which goes into dynamic linking, I suspect it would be better spent on sandboxing (both mechanism and UX).

Ahh. It would be the license if I were to make the decision. Only because, if I were to use Python, performance must not be a big concern, so I would go for an alternative (albeit slower) library (which there isn't a shortage of) instead of paying for the non GPL license.

I think something else that might help is if you make it more prominent (if it's visible right now at all, since I can't find it) the message that tells people, at least, "contact me to arrange a different license", or at best, a pricing model.

I tried to get a big-ticket item using Klarna. Had the money in the bank, just thought I'd give it a go. It failed multiple times without any sort of meaningful error message. Apparently each of those failed attempts hit my credit score. I told them to close my account multiple times through multiple channels (chat/email/etc.) and reverse any damage done to my credit score.

Till this day I get monthly balance/statement emails from them even though I have yet to use a single penny of their credit facility. Too bad they don't use all that marketing budget on competent customer experience/service.
This is probably naive, but I'd love to see one of the Node.js competitors, i.e. Bun or Deno, innovate on the "it takes ~forever to load node_modules every time I run a test/script/etc" problem.

I.e. Bun is improving "bun install" time for projects with large node_modules, and that's great, but what about, after it's on disk, having to parse+eval all of it from scratch every time I run a test?

As admitted, this is a very naive ask due to the interpreted/monkey-patching nature of the JS language, but I'll hand wave with "something something v8 isolate snapshots" + "if accomplishing this requires restrictions on what packages do during module load, deno is rebooting npm anyway..." and hope someone smarter than me can figure it out. :-)
