> While bigger batteries allow drivers to travel farther between charges, they also make the cars heavier, more dangerous, more expensive, and worse for the planet.

Bigger vehicles in general are safer than smaller vehicles. If you are in a 2,000lb car with a 5 star safety rating, you will still probably be killed in an accident with a 6,000lb truck that has a 3 star safety rating. Despite all your advanced driver aids and BS. You will die, and the 1995 Ford F-250 owner will walk away. Mass is the most significant safety feature you can buy. Don't let some journalist in a suit tell you any different. He only wants you to drive the Corolla because he's driving a Suburban.

Personally, I buy cars based on my enjoyment of them. To buy a car for any other reason is silly. None of your friends or family will remember that time you got 55mpg on vacation, but nobody will forget the adventures you can have with a 4x4 on 35's.
Possible Room Temperature Superconductor Replicated by Two Independent Labs
I recently changed job; I used to fill my car every week now every other week. (60 miles roundtrip to 30 miles roundtrip)

I also have some times where I have to drive 10.2 hours(730 miles one way) almost non-stop. When I have to do something like that, I want to drive. Not stop and wait.

The Tesla trip planner with the Model 3 Long Range edition for that drive show it will take 13h for the same drive so about 28% longer with 4 stops @ 30min each.

Realize that people have different use cases.

> If you live somewhere where electric costs are very low then a 0 to full charge your EV costs about $10.

It's not that simple because "full" means something very different in a Cybertruck (123kWh battery) vs a base Ioniq 6 (53kWh battery).

Likewise the fuel economy is dramatically different with the Cybertruck at 2 miles/kWh Vs the Ioniq 6 at 4.6 miles/kWh.

Assuming a cheap electricity rate of $.15/kWh, the Cybertruck will cost $.07/mile to drive.

The Ioniq will cost $.03/mile.

The regular hybrid Prius gets 56 mpg. At the cheapest current (i.e. Texas) gas price of $3/gallon, it would cost $.05/mile to operate.

It will be far less performant than either the Cybertruck or the Ioniq 6, though.

> One of the biggest reason for the massive disparity in efficiency on EV's is due to regenerative braking (16-25%). So what's interesting is when you compare an EV to a Hybrid ICE vehicle then the efficiency disparity becomes a lot less and you still have the benefit of being able to take long trips and not needing a home charger.

The disparity is still around 28%, which when talking about efficiency is pretty big.

> Another benefit to Hybrids is they only require a ~1kWh battery instead of needing a huge 60-70kWh battery like an EV. So you could create 60 or 70 hybrid vehicles for the same amount of lithium mining as one EV.
> One has to wonder why the governments aren't just pushing everyone into Hybrids instead of EV's?

We aren't lithium constrained, we are battery manufacturing capacity constrained. One goal of the IRA (and its EV incentives) is stimulating the build-out of a domestic battery manufacturing supply chain. That battery production capacity is a strategic asset, not just for cars, but also for stationary storage. It's a win-win for energy security and decarbonization.

There are also plugin hybrids that use smaller batteries, but let you use either/both electricity and gasoline (albeit with an efficiency penalty on both drivetrains).

Also, 67% of Americans live in single family homes (mostly suburbia), many with an electrical outlet near their parking spot that they can use to charge their cars. These are also the people who drive the most on a per capita basis.

> If a young person was asking me to recommend a car and they didn't have a home charger I wouldn't hesitate to recommend something like a new Toyota HEV / Honda e:hev - they are basically an EV with an on-board Atkinson engine as a powerplant.

Depends on the young person. For one thing, I wouldn't recommend that any young person buy a new car unless they are very financially comfortable. But if you don't have a home charger (or nearby DC fast charging) it's not a matter of a recommendation, but rather a physical requirement to get an ICE car, so it might as well be a hybrid.
No, for all the reasons stated upthread.
True, but "future minivans" don't help when I needed "now minivans".

And the E-Transit isn't available in a passenger version, I'd've seriously considered it.
I can confirm that some companies leave job postings up to seem like they're thriving for optics, and/or to pacify overworked undermanned teams for a bit longer.

I have had HR tell me that a candidate everyone loved interviewing for us took another offer; except that candidate messaged me on linked in thanking me for the time spent interviewing them, and thst they were disappointed we passed and what could they have done better?

While I'm not a fan of reaching out to the interviewer like that, it definitely confirmed what I thought about that company; we were never going to replace the people we lost, and all those promises to hire more was never going to materialize.

Unsurprisingly layoffs eventually wiped out most teams, and no, we never did hire the three missing positions. But we definitely had ads out for it.

I agree with your sentiment but the article is badly written and misleading. It's not really controversial that there was photosynthesis at the time, it's regarded as widely accepted fact among experts. Also even before the GOE, there was likely anoxygenic photosynthesis, which still exists today in some very primitive organisms. I'm not sure if there's fossil evidence for those going all the way back but to be honest some of that science is questionable to begin with. We're talking about extremely small particles they claim to identify as fossilized bacteria.

There are stromatolite colonies that still exist today, in Australia for example. When students are taught about the history of earth, they're taught such cyanobacteria were among the first if not THE first to produce oxygen en masse through photosynthesis. This was never based on fossil finds but on other evidence. So the paper isn't anything groundbreaking, it's another piece in the puzzle if we accept their images show fossilized thylakoids.

I think you are on to something with a checklist for benchmarking how solid a research claim is:

Where was it conducted:

in silico (simulation only)
in vitro (test tube only)
in mice (or other animal study)

how old is it:
what earlier research does it build on
what other research has been done that replicates or disproves it.

Are you aware of other checklists like this?

Typically, they just replace the cells on the mast. I think $150k is for the fiber, pole, power, etc... The actual wireless gear is cheaper and can be replaced for upgrades. Although I'm pretty sure that 6g or whatever is just going to be 5g with a minor tweak so you have to buy a new phone. 5g is an excellent protocol and will easily last another 20 years.
I’m surprised that this “talent hoarding” approach happens. I’d love to hear from someone who works at a company that does it.

My experience in tech has been that to hire a good employee is expensive. Consuming time from recruiters, HR and hiring managers.

Companies that I’ve worked at that don’t currently require people often lay off the recruiters and HR folk as they scale down hiring.

2023: The Year Open Source Security Supply Chain Grew Up
The closest thing I have to a non-anecdotal answer to this question is from Google: https://opensource.googleblog.com/2023/06/rust-fact-vs-ficti...

> All survey participants are professional software developers (or a related field), employed at Google. While some of them had prior Rust experience (about 13%), most of them are coming from C/C++, Python, Java, Go, or Dart.

> Based on our studies, more than 2/3 of respondents are confident in contributing to a Rust codebase within two months or less when learning Rust. Further, a third of respondents become as productive using Rust as other languages in two months or less. Within four months, that number increased to over 50%. Anecdotally, these ramp-up numbers are in line with the time we’ve seen for developers to adopt other languages, both inside and outside of Google.

> Overall, we’ve seen no data to indicate that there is any productivity penalty for Rust relative to any other language these developers previously used at Google.
I suspect their statement is true if you consider the fully-loaded diameter too -- i.e. fiber + cladding can carry more power than copper + insulation, especially for small gauges.

Edit: Quick google... This paper [1] shows a 180um fiber + cladding carrying 150W over 1km. According to [2], that diameter equates to a 33awg wire, which has 678 ohm/km resistance and a maximum current of 0.072A. At 1km, the wire would be 678ohms. For maximum power transfer, you want the load to equal the resistance of the wire. Thus you could deliver 0.072A into a 678ohm load - i.e. your maximum power would be 3.5 Watts. The fiber is better by 40x.

Toasters are a waste of counter space. Just toast your bread under the broiler of your oven. Sure, you have to flip the bread, but you can do a whole bunch at one time if you're making lots of toast.

You might think "Gee, that's a waste of electricity" using an entire oven to make toast. Where I live, electricity is under $0.15/kwh. It takes about 3 minutes to toast bread on both sides. That works out to about $0.0105 to make toast. If a toaster costs $20, it would take me about 1904 uses of the toaster to pay for itself, not including the electricity the toaster uses. And that's assuming I'm only make the number of slices the toaster can handle (say, 2 or 4?) and not more in the oven.

> You're mistaken, and this is wrong. You need to choose your hardware explicitly for the OS, just like with Macs. Check recommended hardware on the website of particular Linux distribution.

Macs are not equivalent. The OS and hardware are inextricably linked and the OS is not developed to support other hardware, except by dedicated hackers.

Linux however supports a huge array of hardware and explicitly tries to cover a wide spectrum of devices. Same as Windows. Windows does it better.

On the Ubuntu page:

> Download Ubuntu desktop and replace your current operating system. It’s easy to install on Windows or macOS, or run Ubuntu alongside it.

The next page has a list of basic recommended requirements (min 2ghz dual core, ram, etc). If they removed this and replaced it with a hardware compatibility checker, or only offered Ubuntu via their hardware, I would cede this point.

> frame.work do not explicitly support Linux. They default to Windows, and Linux option is only for DIY kits, implying bad support. I'm not considering them for this reason.

From their website:

> We designed the Framework Laptop from the outset to be a great Linux laptop, and the Framework Laptop DIY Edition comes with no OS loaded to let you bring your favorite Linux distribution. We deliberately selected components and modules that didn’t require new kernel driver development and have been providing distro maintainers with pre-release hardware to test to improve compatibility.

> Official support means we work with the Ubuntu and Fedora teams to do our best to avoid bugs and regressions. We provide official support for Ubuntu 22.04 LTS (OEM C kernel) release. We provide official support for Fedora 38 (Intel) and Fedora 39 (Intel, AMD). We provide consistently updated install guides. We provide support ticket assistance. We provide help through the community forums.

They support Ubuntu and Fedora, work with the distro teams to handle bugs, and will respond to support tickets for those distros and versions. That’s pretty explicit.
I noticed that once I stopped responding to my parents questions about how to do all the switching, as soon as there was something important, they figured it out on their own.
Joe Sutter aka "father of the 747" gave a talk at the UW School of Aeronautics and Astronautics after the Challenger disaster in 1986. [0] He was on the Rogers Commission with Feynman and others that investigated the root causes.

The thing that still sticks in my head was his description of the shuttle as an experimental vehicle, which he described as having 700 "critical" components. Critical in this case means that if that component fails you lose the vehicle. He stated that by contrast the 747 had zero critical parts.

It's still the best engineering talks I've ever heard.

You can certainly pay $250 for a toaster nowadays, but all you'll get for your additional money is a higher quality casing and maybe a microcontroller and LCD all surrounding the same toaster guts. Similarly, you can pay $500 for a Kitchenaid mixer instead of $100 for a Walmart mixer, but both will have plastic gears that break in a few years.

The issue is that there's many categories of products where high-quality, long-lasting options simply no longer exist, and where the amount of money you pay has no impact on its quality or longevity. In fact, paying more gets you more bells and whistles that can fail.
If you're interested in actually making this a reality, I recommend in engaging in your country's environmental policy community -- and bringing a lot of patience.

Over at KDE we've some something in that direction - we've worked with the German federal environment ministry on extending the criteria for Germany's Blue Angel environmental label with rules for software products. The resulting criteria include language about what's needed to keep old hardware running and useful (as unnecessary HW replacement spikes the environmental footprint); including using open source to enable the required maintenance.

Eventually, this will have an effect, e.g. when government procurement rounds require bidders to achieve this label, and others start aligning with government practice.

> I believe the process always holds the binary open as a "txt" file descriptor

To be clear, the kernel has an association between the process and the "txt" file (because it is mmaped in), but this is not an application file descriptor (like 0, 1, 2, ...). If an application wants to read from it, and it isn't already mapped by a LOAD section, it needs to open() a real file descriptor.
Yes, I definitely second this recommendation. I used to do IT for a couple architects and got turned on to these kinds of pens, which they use professionally for blueprint markup. They are just perfect for me, too.
I suspect you have not spent any time with a child lately in a teaching context, if ever. Yes, I'm perfectly comfortable saying people have no innate sense of programming, even if I simply discard babies and toddlers (which is a pretty large concession to be making). Some pick it up more easily than others but nobody is simply born with it. Unsurprisingly (for an HN poster), I'm on the higher end of talent myself in general, but I still remember when I realized programs don't need line numbers, how closures work, etc. Pointers was no big deal to me but I still wasn't born knowing about them, and while pointers to pointers posed no conceptual difficulty in what they are in some brute sense, grokking what could be done with them was a process. I don't think even Knuth learned what pointers are and immediately would have derived the Dancing Links algorithm without conscious thought.

They're "intended" to cause only temporary blindness
So again, go ahead and do your bit first. Of course you won't because you don't want to cause yourself even a minor inconvenience.
I can definitely attest that "open position" is a much more abstract concept in the tech/software industry than people think. It is rare for a company to have a slot on a specific team that they have to fill immediately. Hiring is instead more about finding generally smart people and holding on to them. So companies can afford to take as little or as much time as they want in hiring and also can hire 0 - N people for a single open position.
Right, and I would include battery tech as part of renewables in practice. I really hope the next generation of batteries (i.e. solid state, and/or no rare earth metals needed, and more density) is enough of a jump for the wider change to happen.
