It remains to be seen if carbon removal can be done in a way that makes sense thermodynamically (i.e. it takes tremendous energy input to do, where does that energy come from, is it using carbon-emitting energy from elsewhere on the grid, etc). If at any point a carbon-emitting energy source is involved, there's no way that the system is going to be absorbing as much carbon from the air as was emitted for the same amount of energy.

If we're going to flatten the peaks of power availability with anything, it should probably be novel energy storage techniques so that the carbon that is output is not wasted, so the energy is actually used eventually for something productive.

We already have a carbon removal system that is viciously efficient and solar powered: it's called a plant.

Yeah, you're right. I hoped it wouldn't come from the giants, but as a grassroots tech thing, but I guess we don't live in that world any more.
That would be rather unfortunate. If a system generally performs significantly safer than humans, its use should be encouraged.

WOAH - That logo looks 100% identical to scotch.io. Even the animation... Not suggesting anything but wow what the odds.

Great program. Not enough organizations / people prioritizing climate and always great to see efforts by a business.

Also, FWIW “Carbon Capture” is a weird space and a bunch of young crazy tech worth looking into for engineer minded folks (direct air capture for example).

Lot of love, hate, skepticism from people, industry, scientist, activist, NGO, legislators but regardless offsets markets (even a global one) or cutting back is definitely not enough we need to do.
Please, learn C. It's very fast to learn (it's harder to write good code in it, though) and it's pretty much the lowest common denominator that all languages and platforms try to interface well with. It's also much more popular than Rust is on embedded devices.

Most if not all ICs above a certain intelligence level have JTAG, which effectively is a backdoor. All you now need is (for those chips that support it, in the first place...) a way to bypass the OTP fuses "preventing" JTAG access - this kind of vulnerability turns out often enough to be saying it's commonplace.
ah okay that makes sense
I was thinking it was opposite of that which made no sense
Thanks. I'm not a developer so I guess it's relevant, just not for me.
Rust will force you into correctly handling the major footgun of C and C++ - ownership of memory. If you decide that you want to learn C++ later, it'll only take a few dozen segfaults instead of few hundred to get up to speed ('would something like this compile in rust?' is a helpful question to ask if possible)
Btw, this article and associated discussion "If management isn't a promotion, then engineering isn't a demotion":

No, because once their backdoors are (inevitably) going to be found/leaked, they'll come off as liars. Plus, if they would have said no, nobody would buy that or would think they're asleep at the wheel.

"In the teaching of the Catholic Church, an indulgence (Latin: indulgentia, from indulgeō, 'permit') is "a way to reduce the amount of punishment one has to undergo for sins".[1] The Catechism of the Catholic Church describes an indulgence as "a remission before God of the temporal punishment due to sins whose guilt has already been forgiven, which the faithful Christian who is duly disposed gains under certain prescribed conditions through the action of the Church which, as the minister of redemption, dispenses and applies with authority the treasury of the satisfactions of Christ and all of the saints".[2]"

You should really start with C as it gives you a solid foundation both of how things work under the hood, and you'll be likely to have to dive into C from time to time. Apart from K&R, Hacking: The art of Exploitation 2e[0] is a really great book to grok C.

But you can safely skip C++. Rust is a C++ killer IMO.

That anti-trust concern could easily be wiped out by giving non-Apple devices the chance to opt-out by paying a flat-fee of maybe 100$. Then they can say that Apple devices include this upfront cost already (which they kinda do, since they are ridiculously overpriced).
Agreed, this seems like a more immediately effective vector, on multiple fronts.

Let's face it: this 1% transaction fee is going to mostly go into the hands of administrators, bureaucratic types, functionaries, middlemen, and grifters who have gotten themselves into the right place at the right time to proselytize a bunch of catabolic techniques to "capture carbon" that use more energy to capture carbon than was produced by releasing that same amount of carbon. It makes virtually zero sense.

Ok, but how would you (for example) measure the voltage difference over a current-sensing resistor that is positioned at the high-side of (say) a 48V rails?

(If ground was decoupled, that would be simply a matter of attaching probe and scope ground at both terminals of the resistor.)
My understanding is you can self host and pay a sub and get access to all the other features. I may be wrong.
Personal cars will never be the "next public transportation". The density just doesn't work. Personal vehicles are the least space-efficient (to say nothing of energy efficiency) means of transportation among buses, trains, bicycles, and walking. You can't solve congestion issues by replacing a more-dense option with a less-dense one. The only thing self-driving cars solve for is freeing up a person to read or do something else during their commute.
Or something else changed at the same time. Hard to know without a control group.

"On December 14, the Loy Yang coal power plant — one of the largest in Australia — suddenly went offline. In an instant, the grid shed 560 MW of electricity, enough to power 170,000 homes. 600 miles away, the Hornsdale Power Reserve battery system, as the Tesla system is officially known, kicked in within 140 milliseconds. It reacted so quickly, in fact, that the local grid operator was unable to measure the response time accurately. "

If your idea of safety is explicitly that it should be disabled in the places where most traffic fatalities occur (rural roads + intersections) due to rampant human negligence, then I think you should reconsider your definition of safety.

A lot of self-driving is likely to replace taxi service, not make its way to private ownership.

The advantages of individual vehicles for motion around a city are diminished wait times and arbitrary point-to-point linkage. One is not constrained to traveling only on the public transit arteries plus foot-travel distance.

(The tradeoff of fossil fuel consumption is huge and should not be ignored, however).
This sort of thinking coupled with increasing ease of litigation is why general aviation is more expensive in real terms than it was in the 70s.

The nice UI for review works well exactly because it limits the functionality available to users and enforces a particular commit model. If you don't do that, you get the code review mess that are Github/GitLab PRs/MRs - difficult to tell apart how commits relate to the change and how it progresses through review, because the entire branch history is free-form.
The best part about NixOS is I can hack around on Linux through it fearlessly (due to immutability). And once I do something useful, I can abstract over it so I (and others!) never have to solve it the hard way again.
I guess my point is that why aren't we making new things? Is the appeal to nostalgia such a money maker that it's stifling new creative endeavors? Could there have been a fun product that is a futuristic space spaghetti western that isn't Star Wars branded? Is being an appeal to nostalgia a requirement for a fun product?
What you say is untrue. Black hats have done things on this scale for as long as this scale has existed.

RATs, malware, spam, ransomware, scareware, worms, all this existed in the largest scale possible before the advent of crypto currency.

Doxing, messing with people, leaking sensitive files, pictures and other media, has existed on massive scale before crypto currencies.

It's the scale of the internet itself, and the amount of money involved, and the fragility of connected systems, that has lead to the increase.

I'll grant that cryptocurrency adds even more of this badness. It's definitively increased the number of bad actors. But this is not the driving cause.

Their 'obvious role' is only a role for some actors. Not everyone is financially motivated.

It's also easily measurable, the revenue of a ransomware-as-a-service group (this exists) is an easy jaw-dropping number to display.

But that number does not capture the damage done by actors not financially motivated. Hell _the_ largest and _most_ devastating attack ever was not financially motivated at all. I'm of course talking about NotPetya. Whose damage and impact easily dwarfs that of the financially motivated ransomware groups.

I say learn Rust and C in parallel.

I'm learning Rust now after several false starts. Here's what I find challenging and interesting about Rust: most languages exist on a spectrum between faithfulness and abstraction, where they either represent the underlying hardware in an accurate way (like C), or they provide high level abstractions that allow you to simplify your mental model of how a computer works (like python).

Rust is interesting in that it uses abstractions which don't lead to a simpler mental model. There's no such thing as 'lifetimes' from the computer's perspective. And yet these abstractions, though somewhat artificial, can still shape your code in beneficial ways.

I think that learning Rust without having exposure to C would make it difficult to recognize which constraints that Rust imposes are based on actual limitations of the machine vs Rust's particular paradigm. So I say learn them both.
We know that just one of the NSA's related programs, Bullrun, had a budget of $250 million a year from 2011. And by their own admission this gave them access to "vast amounts of encrypted Internet data which have up till now been discarded are now exploitable". Further, their reports mention much more activity that Snowden did not have clearance for.

We don't know the full extent of their activities, but it clearly far surpassed what should be tolerable.
Also, isn't it easy to make FFI calls to C/C++ libs from Rust when you need to interface with an already existent codebase?
I find it interesting that such rapidly falling cost actually slow down adoption. My parents will have to renew their houses roof next year and obviously, adding solar with a battery would make sense. However, while doing so would technically be cheaper than buying power from the grid, it would be even cheaper to do it in two (or four, or six ...) years to come as batteries will be even cheaper then. So they probably will not buy them now.
It's often been hard to run Linux, and the expectations of Windows are very low. When I was being pressured to switch to Linux by peers, it was because of the crappiness and instability of Windows, not any particular merit to Linux (other than not crashing constantly and not having to be restarted after every update.)

edit: I have to say that I don't use netflix or play video games.
The Wikipedia article is just for the fatality statistics. The expectation of airliner reliability for self-driving cars is what I get from the discussions around this. Here on HN and in other places. Maybe it will be lower and the uncanny valley will be smaller but I wouldn't bet on it. People are much more afraid of flying than of driving even though driving is much riskier. And that's because you're much more willing to accept risks when you think you're in control of them. Self-driving cars will take that illusion of personal control away.

IMHO: Learn both but start with Rust. Rust forces you to think about memory management topics (memory lifetimes and ownership) which you will also need to know about in C++, but in C++ you are entirely on your own so it's easier to "slip into" bad memory management practices (which you would need to unlearn again when moving from C++ to Rust).

You should also include C in the mix (very different from C++(!!) that's why "C/C++" is a bit shunned upon by some people), because Rust or C++ are often overkill. If you're tackling Rust and C++ anyway (which is essentially a lifetime task), learning C on the side is literally a "weekend project" ;)

Just remember that C and C++ are not as similar as many people believe, they are different languages with different goals and a different philosophy.

One SDC takes up slightly less space when we factor in the necessary buffer around human-driven vehicles to account for human reaction times and safety perception.

A fleet of SDCs snaking down a road can "tuck in" tighter to each other because computer reaction times are better (especially if they're networked and sharing decisionmaking signals).

Of course, it's still not as space-efficient as a bus. But the bus infrastructure as a solution has been challenged by COVID-19.
Carbon capture is necessary in the long term, for particular emissions that are hard to avoid (like specific industrial processes and parts of agriculture). But while we're still pumping out emissions that can be easily and cheaply displaced today, like coal and gas fired grid electricity, then the money being spent on carbon capture is being spent terribly ineffectively. And globally, we don't have the time or money to waste.

For example, most electricity grids are still partially carbon-intensive, despite renewable sources being cheap and available and in use. Simply buying some more solar panels and hooking them to a carbon-intensive grid will displace coal or gas emissions by the following lunchtime, far more cost-effectively than any form of carbon capture.

I understand the principle on working on research projects that have a long lead time. But Stripe should treat carbon capture as such, and could have a more cost-efficient climate strategy: put most of this money today into the most cost-efficient solutions available today, rather than putting its entire budget into the least cost-efficient solution.

If humans are electrical brain signals in a bio computer, everything done is entirely arbitrary. This historically the reason why many people fear atheism.

So I say this having used XCode about 10 years ago, but is XCode really that bad?

Around 2000 or so, I was installing the Visual Studio -- Pre .NET Version -- on a number of new developer workstations. I was not a Helpdesk or Desktop tech, but worked supporting servers -- they sent me over to do the installs because invariably "something wouldn't launch". Different IDEs were used depending on what language you were writing in with this monster of an app that was used to write programs in Visual Basic[0]. And the program was 5-10 times larger than the largest installed application and came with 2 CD-ROMs worth of documentation that needed to be installed locally[1]. I remember I'd start all of the installs at the same time because they took several hours to complete.

[0] If it isn't obvious, this was a one-off job that I don't recall very much about. I didn't start using a Microsoft IDE until the first release of Visual Studio .NET (retroactively renamed "Visual Studio .NET 2002", I think).

[1] For the younger among us, that's about 1.5GB in a world where two years earlier 16GB of HDD was very expensive.
