> Modern jet turbines are running within a few % of maximum thermodynamic efficiency.

Indeed they are marvels of engineering. But that doesn't make them "sustainable". It just takes a lot of energy to push something through the air at high speed, no matter how efficient the engines are.

Apart from the CO2 emissions, there's also the issue of the GHG forcing effect of high altitude water vapor emissions. Current estimates are that flight at typical airliner altitudes of ~10 km results in a GHG forcing (over some decades) of roughly 3 times more than burning the same fuel on the ground.

> And for that matter, how would biofuels possibly be worse fossil fuels, given that the whole point is to not emit net CO2 into the atmosphere. Obviously it's "efficient" because all the energy we put in has to come from the sun, rather then obtained for free but that's the point.

The major issue is due to land use changes. Biodiversity is already in a sharp decline (arguably this is an as big, if not bigger issue than climate change), largely driven by converting nature into cropland. Secondly, converting nature into crops, whether for fuel or food, tends to result in large CO2 emissions due to the carbon that has been stored into the soils being released.

And finally, biofuels just don't scale. There isn't enough arable land on the planet to replace the amount of fossil fuels we use today.
Yep. Even for video games in my teens I created and led a clan. It was very social and constructive for me.
Yeah, but awaiting and expansion were in there so I guess we can cut it some slack perhaps.
They did not run Lisp as machine code. They either ran a machine code, which Lisp was compiled to, and/or they ran a Lisp interpreter, which ran Lisp source code. The machine often was kind of a stack machine, with microcode implementing the instruction set.

Cool! What didn’t occur to me until I learnt it was that you get a multiplicative benefit with energy density when weight is a major factor (air transport, especially) because you need to spend less energy accelerating mass used by the battery itself.

Farming causes environmental damage besides greenhouse emissions. Even discounting all the other forms of environmental damage, a lot of biofuel schemes (e.g. corn ethanol) emit more greenhouse gases than they save.
> an externality credit/tax, system, would resolve these issues.

This is a good approach to a lot of things, except when said thing also has positive externalites and second order effects associated with it.

Travel is one such example, as it's essential to lubricate the economy. As such, we should encourage as much of it as possible. Business thrives on it.

Without cheap air travel, America is weak. We lack commuter rail infrastructure, and car travel is far too slow. Taxing air travel or increasing its costs are a nonstarter.

If we predicted the era of air travel to be coming to an end, we'd be making rail investments. Air travel is likely to continue growing, however, so there's little rush for domestic rail projects.

America flies.

I wouldn't say any of those bullet points are inherently better - just differences for you to contemplate. For all the downsides of these things, there are artistic uses of each that sadly are not an option on modern video platforms.

Example - mystery runtime, while inconvenient to someone in a hurry, is useful in keeping suspense or surprise. It's kind of hard to convince a reader that the hero is at risk of dying when there's obviously 2/3rds of a book left.

Do the pros outweigh the cons? Probably not. Should it at least be an option on modern video platforms? Maybe. But the important thing to me, is that we remember how such a thing changes the viewing experience before every film for the rest of time comes with a progress meter attached.

Ask HN: Would you be interested in a tool to manage your local dev dir?
My ~/dev dir is a mess. Hundreds of cloned open-source projects. Work projects. Side-projects. And multiple worktrees for each repo.

I'm thinking of building a cli + gui tool to manage all the code on my computer.

I also think that debugging project dependencies is too difficult.

And I'm not just talking about your project's package dependencies. Or even your package's native dependencies. I'm talking about system-installed native dependencies...such as postgres, chromium, the node.js runtime, electron.

Many tools for high-level languages are being built in system languages like Rust and Go. E.g. Ruff, SWC, esbuild, etc.

All these native deps are difficult to setup debuggable local build envs for, and also difficult to integrate into your project. Think about working on a Node.js project and wanting to set a breakpoint in the Node.js runtime. It's non-trivial. Strange build instructions, pulling sub-modules, setting up your IDE, running your script with debug flags.

I think it might also turn into a replacement for homebrew. Instead of installing from bottles, repos would be pulled down along with all their dependencies, and git worktrees would be setup to link them together, and setting up your IDE for debugging would be one cli command.

The goal would be to make it super easy to set a breakpoint at any piece of code executing at any level of the stack. There would also e a simple git workflow for submitting a patch.

I also envisage a visual dependency graph to manage everything.

The final piece would be making the kernel debuggable as much as is possible.

I'd also like to have a GUI for all debugging tools for different types of problems, to avoid hunting down the right cli tools. And also a GUI for all configuration on your computer such as `~/config` stuff but also env vars, also showingl dependency graph and override chain.

Just some thoughts.
Cyclists (of both kinds) are also rare enough that people are usually “surprised” by them because they can be in a blind spot much smaller than a car.

Interestingly, I'm finding more and more standard vehicles with tires with the M+S designation on the sidewall that makes them legally Snow Tires.

Good question. I tested heaps. The winning design by a landslide was a metal plate reflector, with essentially two diamonds around 15mm in front of it, side by side, apx 15mm on the edge.

I thought it was called a 'butterfly antenna', but web searching now I don't think that's correct.

I built one for a friend just with wire and pliers. The tolerances mustn't have been that important because it worked well.

Maybe someone on here knows the name of that antenna design?
This is the different sign of the same coin.

Not you, but JD controls the kill-switch.

They can disable a device to render it useless whenever something happens that they don't like.

Whether it's theft or violation of your leasing terms.

If the owner was in control of the kill-switch, it would still have all benefits of theft protection, without the problems that arise with a manufacturer controlling devices indefinitely.
"It's difficult to attribute the addition of bureaucracy or increased costs to a specific U.S. president, as many presidents have overseen the growth of the federal government and its bureaucracy throughout American history. However, it is worth mentioning that Lyndon B. Johnson's administration, during the 1960s, saw a significant expansion of the federal government and the creation of many new agencies and programs as part of his "Great Society" initiative. This expansion led to increased bureaucracy, which some argue made certain processes more expensive and inefficient. But it's important to note that the intentions of these initiatives were to address issues such as poverty, education, and civil rights, rather than to intentionally make processes more costly or discourage people.

You would be wrong, the handbook (and presumably the law it derives from) states (or at least stated when I took the test) freeway driving is a mandatory part of the driving test.

I asked the instructor why we skipped it, and they said it was because the freeway portion "is too dangerous for the instructors".

I had a good chuckle that day.

Not really. Apt installs snaps in some cases not because they’re tricking people, but because said package is either abandoned by Canonical team like firefox (Mozilla creates snaps for it, so neither Canonical nor Mozilla have to build debs for all the Ubuntu flavors and supported versions anymore), or created so people can help Canonical to test technology like it was with gnome-calculator several years ago.

There is also the more general meme called the “secret third thing”.
I don’t see any scenario where this is worse than the status quo in the narrative put forth by grandparent comment. Is the implication here that the end result of the efforts mentioned is somehow more greenhouse gas emissions? If so, I would love to hear more of the rationale and statistics behind it.

As much as I like the idea of checkbox toggled panels, it’s worth pointing out that that technique is inaccessible.
Thermodynamic efficiency is the wrong way to measure efficiency here. It makes no sense to measure efficiency that way, none at all.

I’m talking about biofuels as they exist today, not as they hypothetically exist in the future. Currently, you burn biofuels, you end up releasing more CO2 into the atmosphere, because the production of biofuels produces CO2. It’s not negligible, either.

All of the analyses I’ve seen of biofuel paint an incredibly dismal picture. As far as I can tell, the main strategy to reduce CO2 emissions is to stop burning fuels altogether, not switch to something like biofuel. Airplanes need power density & energy density in order to work which makes technologies like batteries unsuitable. Way easier to power something on the ground, where you’re not spending tons of energy just to keep it from crashing. Or better yet, on an electrified rail.

A few years a back someone had the genius idea of making a robo-answering phone program that would give vague but encouraging replies when it received some unsolicited sales pitch. Although it was a fixed sequence of responses, it fooled some callers for a surprisingly long time.

https://www.youtube.com/watch?v=XSoOrlh5i1k

Someone needs to hook create the plumbing to capture speech to text, feed it to a GPT script that has been told how to reply to such call center calls, then send that back through a TTS generator like this one.

To overcome any latency issues, it could build in a ploy to buy time like the old script did, eg, make the robo-answerer sound like a somewhat addled old man who has to think before each reply, perhaps prefixing responses with "hmm, ahh, ..." to buy time to generate the response.

I assume it's a limit motivated more by how far you can go rather than the cost of fueling/charging. Like, above a certain weight/energy store ratio, it's either too heavy to fly or would just have an incredibly limited range.

Yeah, but those are signs of it being not Microsoft, not "not native". At least back in those days, "native" meant "compiled into an .EXE file that runs directly on the hardware" (as opposed to, say, bytecode that runs on a VM (that is an .EXE that runs the hardware)).

To me, it still does.
I wonder whether this was at all influenced by SPARC Solaris's 8K page size. Sun was still a pretty big player in the internet and networking around this time.

Or maybe it's transitive, 8K pages influenced NFS transfer size, or retrospective, NFS transfer sizes influenced page size (I don't know the history of Solaris page sizes or NFS protocols).
You could just out an SQL server somewhere and connect it as a datasource to Power BI. If you’d prefer a more standalone and SQL oriented Open Source solution, go ahead an checkout metabase as a BI platform.

One thing I don't understand about the AI "ethics" debate is that it's a debate about the behavior of a singular system. One single AI. In this case, Google's.

Do people honestly think there is some happy medium that everyone will agree with for standard behavior of a machine that is attempting to emulate the human mind?[1] Of course there isn't. Humans exist on a vast spectrum. It seems we're somehow arguing about one machine that attempts to emulate that spectrum.

ICE engines only manage to turn ~15% of the stored energy in gasoline into actual work. A bit of googling suggests that jet engines are about 35% efficient. Stored electricity is much more efficiently turned into mechanical work... Electric engines have 75-90% efficiency. So, you get a lot more work or unit of stored energy.
