I don't know why you are downvoted, those are exactly the main steps to reduce one's emissions.

I have heard somewhere that emissions can be divided roughly in 4 categories:

- Transport. To reduce this category, you need to travel less and if you need to travel, go by foot, bike or public transports.

- Food. To reduce this category you need to reduce you meat consumption, 2 or 3 times a week is enough, buy less transformed goods, ie cook more, and buy local grown food.

- Consumption. To reduce this category, follow the 5 R: Refuse, Reduce, Reuse, Repurpose, Recycle.

- Public emissions. This one is tied to all the public services we get. It can only be reduced by reaching agreements as a society.

As for the children, obviously if we all stop having children, this is all of no use. In developed countries we already have stabilized our demographic growth, so I don't think there is a need for limiting oneself.
I had no idea. Where can I read more about this please?
I do think that a consumption-based tax can be implemented for PHEV's using the data from the onboard computer. When you pay your annual tax or go for the inspection, you either take a readout of the car's consumption metrics from the OBC or have the shop/DMV do it.

Then you charge tax based on the consumption. Thus, someone who used electric a lot gets charged less than someone who didn't, which is what the incentives for PHEV's are supposed to encourage anyway.

>Plug-in hybrids are fake electric cars, built for lab tests

That is a very reasonable assumption. Euro emissions legislation makes it practically impossible to sell a new ICE-only car, so hybrid cars are designed to be the nearest thing while fulfilling the letter of the legislation.

Flash (Animate) is still my favourite mockup and design tool. It used to be so much more powerful in that you could export to a lot of different formats. And when your output is just some standard format, it didn't matter what the creation tool was. I could manoeuvre faster in that application than any other tool.
And the bonus was that for anything you designed, it was almost trivial to animate it. I now find myself doing svg animation using it + plugins.

Macron tried that in France, and got a huge upheal from poor people.

It's also not fair to people who bought their car already, because they had to calculate with the price of gas to see if it's worth it for them.
> I dislike the mere concept of Super Mario Run; from what I know of it it's one of the most cynical examples of mobile games; minimal gameplay, maximal monetization

That is completely untrue and completely misrepresenting the game. It's basically the opposite of the truth.

It goes without saying that if you know (or guess) the model or function you are trying to implement, then you don't need machine learning.

Toy problems like this are still interesting because they demonstrate techniques that are applicable to bigger problems. I'm guessing the network in the car game doesn't need more than one layer and two outputs (acceleration vector), but that is besides the point.

The technique being demonstrated is the ability of GA (or maybe particle filters), to find "optimal" weights for a network given whatever simulator. This is always interesting, especially when done with graphics like this.

I do think PHEV's are a good stop-gap, especially given that Li-ion batteries are expensive and there's not enough manufacturing capacity for the demand. Meanwhile there's plenty of experience and R&D that's gone into optimizing gas engines.

Most trips are short and easily covered by battery. The gas engine then comes in on the highway. I really think that's the best of both worlds. Especially given that BEV's aren't cheaper or lighter - because the missing gas engine's weight and cost is more than compensated by the additional batteries needed.
$169B for 29,000 lives? Study calculates cost of US shutdowns
why? hybrid brings efficiency of the gas engine to that of the diesel (and better than that in the city) while being much cleaner. 15-20 years ago (the first years after coming from Russia where diesel was definitely a better option back then - and my father had diesel VW Passat there at the time :) i thought that the diesel was the way to go and was disappointed at California for the "anti-diesel" law, and only later understood that it was a right thing to do.
This the same argument that the NSA used when they claimed they weren't listening to everyone's phone calls: it was just algorithms parsing the data so that's 'ok' then.
Hear hear. Right now, sadly - crypto is the only thing that allows you to directly convert excess energy into money, without a surrounding infrastructure.
Reminds me of the first time I saw that stackoverflow page comparing hash algorithms (from crc32 md5 xxhash to sha) thru patterns it generated onto an image. Also answers by the zlib guy, the nagle algorithm guy. Explanations like those just blow my mind.
this paragraph shows the bias

"The BMW X5, Volvo XC60 and Mitsubishi Outlander emitted 28-89% more CO2 than advertised when tested by Emissions Analytics on a fully charged battery in optimal conditions. On an empty battery, they emitted three to eight times more than official values. When driven in battery-charging mode, which could become more common as motorists charge up ahead of using electric mode in low-emissions zones, the PHEVs emitted three to 12 times more."

1) when empty, they emit more CO2 than their average assumed values. this is obvious. its just using gas, no battery.

2) when using the gas engine to charge the battery (i.e. instead of just generate enough electricity to move the car as desired), of course it is the worst performing. you're running the generator at full blast.

I had a Chevy Volt in palo alto where I was able to charge every night. I used it for commuting around (including a regular weekend trip to SF and other trips as far north as berkeley). As I was able to charge regularly (either 220v or 110v), I filled up the gas tank once a year (and that's because the car forces you to not have gas over a year old on average). Now, I don't have the ability to calculate how much CO2 was produced because of my charging times, but in terms of actual CO2 produced by the car, I'd put my experience over any other traditional ICE car.

Similarly, drove the car cross country. While I wasn't able to charge regularly, the electric motor handled the ups and downs of the terrain much better than all the other ICE cars I passed with ease.
Oh, I was not defending neural networks. This was the cynical sales pitch for the case where you don't want to employ mathematicians or computer scientists, but just throw code and computational resources at the problem.
This book is great, but now more than a decade old and the author is sadly deceased. It would be great to get an updated version which includes advances in renewable and battery technology. It is also focussed almost exclusively on the UK. Would be nice to have a version to cover feasibilities for all countries.

Edit: if memory serves, it also doesn't really cover carbon capture?

Yes, let's revolutionise the financial system by making sure it takes up 95% of our energy use! That's only 5 orders of magnitude more than currently.

The parent commenter didn't say that everybody should use ML in all circumstances. Real world tasks are often more complex than invented toy examples, and quite often hand crafted policies don't work so well. And it was not elaborated in the original blog post. So I think it was a valid point.
Very interesting link, as discussions on energy are meaningless without data. My understanding is that simple back-of-the-envelope calculations show that energy demand is the fundamental issue.

That being said, I've read that "without hot air" is a bit outdated and should be updated to reflect recent progress on renewable energy and battery technologies.
I also live in Germany and the last Firmenwagen I was assigned (this year) was a diesel Passat. A PHEV would have been an improvement.

Its a chicken vs egg situation. If they had given me a PHEV, I would barely have been able to use the battery mode because of the lacking infrastructure and defective Ladesäulen (charging stations) everywhere. However a few colleagues of mine have houses and garages, and for them it would have made a lot more sense. However all of us needed to cover long distances for client visits and thus, BEVs aside from Tesla LR models were totally out of the picture.
I think this is just a misunderstanding: the ad got targeted at the wrong person.
All my friends who bought a new car can afford an electric car as well. Buying a new car in itself is a luxury.

The problem is that hybrid cars are often misused by 400% of their allocated quota, which can't be done even with the volkswagen that was caught cheating. I'm OK with hybrids, but definately not OK with the CO2 allocation that they get away with.

The concepts and equations he has are pretty simple but I'm really not seeing how they translate into code.

The code also isn't the easiest to try and understand for me. Multiple 1-3 letter or otherwise (Seemingly) poorly named variables, some C jargon I'm not familiar with (Mostly the -> operator) and the fact it's a relatively large chunk of code.

> For the ignorant software only folks like me

TL;DR: Software is eating the world.

First, it doesn't, but it can be easier or cheaper if you use one. You can build a closed-loop controller using only analog electronics, but it doesn't mean you should. Because silicon is so cheap, sometimes it's reasonable to use a $1 microcontroller and 20 lines of code, instead of 3 opamps, 5 resistors and 3 capacitors. I don't mean that software is always a good idea, but you get my point.

Next, if you want an LCD-based user interface (it doesn't mean you should, you can use an analog potentiometer, but having a display is the norm these days), you need a microcontroller anyway. You need a microcontroller to control the pixels on a screen or the numbers on a seven-segment display, and you also need software to implement functionality such as "press this button to change the temperature", or "save the current settings".

Also, these "novelty" soldering irons can power themselves via USB Type-C by using the USB Power Delivery protocol (it doesn't mean you should, but people are having fun doing it), which is a digital protocol, you definitely need a controller and software to do the handshake in order to get DC power. A single microcontroller can perform this task as well.

Now, does it really need a RISC-V microcontroller, instead of, say, a 8-bit 8051 chip? No. But the target audiences of this soldering iron are hardware tinkers, and previously they already ported things like Tetris and Game of Life to the soldering iron, so... Why not?
The Terms of Service cover the usage of the Launchpad website. The website is a service created by the Ethereum Foundation to guide users through the procedures required to join the Ethereum 2.0 network as a validator. You don't need to use this website (or agree to the TOS for the website) to participate in the Ethereum 2.0 network. The technical requirements and procedures are fully documented in other places (in a more technical less user friendly manner).

I imagine they added a ToS to avoid "I used your website and I lost all my money"-type lawsuits.

They key metric here is how much it costs ($/TON of CO2 Captured and Sequestered). There are a range of methods and approaches to do this. The average cost for Air Capture across modern approaches is $250/Ton of C02 Captured and Sequestered.

There are other approaches besides Atmospheric Capture and Sequestration which hold more promise
1. High concentration C02 Emission Capture at source
2. Ocean surface capture and de-acidification

Wrote a quick article describing all of them linking to specific research papers and their results here https://www.projectcelsius.com/2017/05/29/capture-methods/

I expect this will follow a similar journey to how solar panel adoption went... once things tipped over the critical ($/KWH) where it made sense over grid electrical, people started to adopt. I imagine once one of the techniques reaches a critical $/TON Captured & Sequestered, governments or institutions will pay to build whatever machines to start. Right now things are too expensive using any method (i.e. using the best method, it would cost ~$12 Trillion dollars to capture and sequester ~49 Gigatons - the estimated carbon emitted in 1 year by humans in 2020)

I am not your opposition on this, just stating how the law currently looks at it, and citing the precedence that has been cited before, specifically gun control in the wild west. That being said, I am OK with it being a privilege if it were a universal shall issue. I would prefer that it be decided that it is a universal right, but I am ok with either outcome. I am not a fan of may issue as it tends to be a privilege that only well the privileged gets to enjoy.

With all that being said, I see magazine capacities, foregrip bans, scary gun cause it is plastic and black and those kind of rulings as a direct affront to the 2A because they apply to stuff in my home, I would be a felon if I lived in those states, literally one day I would be legal and the next I am a felon. With no recourse, even the Automatic Weapons Ban in the 80's allowed for the FFL 3 classification and the tax stamp to keep the weapons one already owned and while I am not advocating for a grandfathering of reasonable capacity magazines, and black rifles I am citing that in the AWB there was at least a path to keep your existing stuff legal.

This is, to put it mildly, bollocks. Bitcoin uses more energy than the entire finance industry to supervise far less capital and conduct far fewer transactions (by multiple orders of magnitude). You are equivocating by equating levels of inefficiency which differ so drastically you are either deliberately misleading people or have been mislead yourself.
While hybrids can help reduce overall emissions, it also matters where the emissions occur. Running on batteries in the city reduces emissions (to zero) in areas that already have terrible air quality. For longer journeys outside of the city, the air quality is better and there's less population density to be affected. So they can still be a net win even if they are just shifting emissions from one place to another.
Everything is connected. Since the government, despite what people seem to think these days, still represents something between 30% (only government directly) and 60% (government + contractors + fully dependent on government + ...) of the economy in the US, it can easily explain a 3% trade deficit.

But again, the actual spending is NOT the problem. Nor is the trade deficit. Using sovereignty (ie. government spending inflation) to take away normal people's ability to negotiate with accurate information (and voting) what their fair share of the economic pie is. THAT is the problem.

We could double government expenditures without causing a real problem. But if we double them and only 1% of people go to their boss "I need a raise" because they just don't know, then it'll be really bad: they'll have to compete for goods and services with the other side having double as much money as it does now.
I agree with your general comment, but since forests can be used for construction materials they come out a little better than merely being a buffer since the wood gets used in housing or manufacturing in places where steel or concrete would need to step in, both of which are much worse for the environment. If built with longevity in mind, wood framed houses can last around five hundred years, which is more than enough time for technological advancement to allow us to deal with excess carbon by then. Even if they're only designed as typical buildings are, it's still a good fifty years of buffer as wood in a house in addition to the buffer as they were growing as trees.

Forests are a real part of the solution.

The state spends a lit of money on violence and projecting it. Why?
