I think this has been discussed to death, the TL;DR is that H2 is fundamentally really difficult to store safely and efficiently at reasonable densities and temperatures. This is not something that is likely to improve with technology or scale (it's not like it's an underfunded area), they literally squeeze past other atoms and nothing is smaller than hydrogen.

I do however agree that existing battery technology is _still_ severely disadvantaged, not only in terms of efficiency and density but the rare materials they need to manufacture (same for H2 solutions).

It's annoying because ICE engines are not great (big, heavy, complicated with related reliability issues), yet they consume an easy to transfer high density liquid fuel; Electric engines are fantastic (small, light, simple, highly efficient, powerful, great torque), but they consume electricity which is hard to efficiently transfer with no where near the energy density per unit weight or space storage solutions.

However! ICE exists, all of it's issues are mitigated by mass adoption, and in the short term it's not environmentally responsible to ditch 1 billion cars. I think the best plan I've seen so far is to scale up synthesising hydrocarbons from solar... electric cars can continue to be developed and we can find more reasonable electric storage solutions without undermining the purpose of switching to electric by forcing the world into an immature solution and throwing away 1 billion ICE vehicles and all related infrastructure (manufacturing EVEs has an environmental cost).

We like simple to understand solutions, but the solution that minimises environmental impact must not underscope itself - the whole picture has to be considered, costs of manufacturing and switching are not external to planet Earth, which means there is some ideal conversion rate that must be determined.
Finding Raspberry Pis with Raspberry Pis
I'm in a surprising situation right now: I've just inherited a huge, well written C# .NET project that's not generating much value to the business. Too much boilerplate, too much unused models and extensions. Things like that. It's weird because every single piece of code seems well written and well documented, but this mammoth solves a very small part of a small business, leaving the internal users to reach out to spreadsheets most of the time.

His reasons for returning to the office is a twist of something that management has been marketing often "change the world", so forgive me for being skeptical.

> But living in a walking city with a car is even nicer!

I think that's fine. Most over time will realize they don't need 2 or more cars if they're living in a true walking city because driving will be more inconvenient than walking, and eventually either paying for or building a garage (or having it used up by 2 cars that are seldom used) or paying for street parking or other things will cause people to change habits. It just takes time if you have a walkable city.

Personally I think the sweet spot is one crossover SUV, highly walkable and bikeable city, and probably street cars that run up and down main commerce arteries. At that point you really do cover almost every conceivable local transit need or chore that you might have to undertake.

General purpose humanoid robots. They're kind of mainstream idea, but very few people talk about them or take them seriously.

Humanoid robots will have an absolutely massive impact in very near future.

Most people don't realize that with general purpose humanoid robots, labor becomes software. Labor becomes repeateable, testable, simulatable, modular, extensible, verifiable, etc. All things that apply to software will apply to labor.

Imagine pulling an open-source repo from Github for a log house. If you want, make changes and simulate the output beforehand. Put your robot in a forest with a few tools and soon you'll have a log house - built perfectly to the spec.

Labor also becomes abundant. There's no more need for humans for economic growth.

Tesla is showing their first humanoid robot prototype in September. I predict that Apple will soon follow.
What do you mean by "this pseudoscience"? Climate change? Runaway climate change? Climate change is already happening. At what point it becomes runaway climate change is a matter of definition and debate, but there are definitely some processes that reinforce climate change.
If I can take the outrage down a notch, political parties survive and thrive on opposition, especially in a two party system. "If the other side wants it, we're against it" is the motto of both American political parties. A voting system that could encourage a multiplicity of political parties, reducing the attractiveness of pure opposition, would be a huge improvement to American politics.

Reasoning it through, what don't people politely talk about? Sex, money, politics, and religion. Sex: the impact of the normalization of casual sex work on sustainable families, and how specific tech and financial services for managing single motherhood will be huge. Money: financial alternatives to emerging social credit based systems, grey markets, working class capital/savings flight, cyberpunk dystopia. Politics: polarization becomes relative isolation, increasing demand for parallel tribe-based economic and information services. Religion: pendulum swinging back from civic secularism among those disenfranchised by said secularists. Reconciliation of old time religions with current tech and science. The christianization of fringe ideas like "ancient astronaut theorists," conspiracy theories, simulation theory.

True or not, they're big and not talked about in polite company.
They're also probably smarter than average, because people who are smart are more likely to become rich. But I'm worried this will accelerate the effect. On the other hand, if you make the technology available to everyone, the effect would be mitigated

Agreed. I chunk slack messaging the same way I do email. I have two channels that I'll take realtime notifications on, but if someone raises those flags without very.good.reason, they'll hear about it. I generally won't see anything on those channels more than once a month.

For special 'war room' projects I'll set up a special channel that I'll pay attention to for real time colab, but those are very unusual situations with a well defined end date.

I agree that it’s going to be painful. But it’s going to be painful either way because power plants take too long to build and we have an energy crunch now. We need to get power from somewhere and the only immediate solution is to level load the grid more efficiently.
I do not think this is something that will make our lives better but it will make more efficient use of our existing power infrastructure and its something we will all have to deal with

I agree with him but for completely different reasons. I think his perspective might be influenced by his profession a lot. To me WFH wasn't the right thing, but I live very close to my workplace. If I needed to travel my opinion would change drastically. Best compromise would be a combination of both. 2 days office, 3 day WFH or something like that. And of course I need an office, nothing can convince me of open office or cubicle. That isn't a company, that is a plantation.

Definitely a problem, though at least where I'm at (Idaho) it's generally the case that they are actually doing something that requires blocking SOMETHING and I get why they choose the bike lane over the sidewalk or road.

That said, there are times when they just store their cones in the bike lane, and that can be super frustrating.
I don’t consider that to be insight porn, which is why I found it personally valuable. I feel this is a fundamental law of getting anything done. There’s almost nothing that I actually want to do for extended period of times, but I want the result from having done that thing a bunch. For example, it’s really hard to go outside and practice archery every day, but I have to do that in order to have the result of those skills - a successful archery hunt. How do I get the results when I am way past the first month or so where motivation is waning? I have to have the discipline to work toward my goal, regardless of how I feel in the moment.

I found this insight for lack of a better word to be so fundamental that I was floored when I read it in jocko’s kids book. I saw my dad do this, he clearly embodied this value and demonstrated it while raising me, but no one ever explained it to me.

For a goofy comparison, I would consider “discipline equals freedom “ to be love making between a happily married couple, and blog spam insight porn to be actual porn.
One thing I've been thinking about is, how do you scale tourism?

Edit for clarification:

For example, the destruction of local environment is a known problem for places such as Machu Picchu and Venice, to the point where you now need to reserve and pay for a visit to the city of Venice [0]

As population gets higher more and more people want to visit the top destinations, and when a new one gets "found" it gets flooded (see Dubrovnik after Game of Thrones hype)

Because of physical limitations these experiences don't scale - there's a finite number of destinations in the world and an ever-growing population.

Agreed.

Rogue black holes, gamma ray bursts, or even the very fundamental constants of known physics shifting to a more stable form and that new rule propagating at light speed imperceptibly — and countless, countless other possible dangers. We are no where near the technological level to deal with these, as we cannot even deal with simpler world-ending events (meteor strikes, desertification, proper stewardship of emerging AI, nuclear war).

In addition to all the other reasons one can muster, our advancement in technology can easily be motivated and justified by the objective of Earth preservation and propagation.

It will be interesting to see, however, as we potentially discover other forms of life maybe in places we actually think are barren, how we as a species cope with that. But we are not even remotely at that problem space yet.
>"if you're the right sort of person, you have the right sort of hunches"

To me, this sounds like a line from a multi-level marketing pitch. It sounds like they're saying "This may not apply to you," but a lot of people will hear "There are chosen people (and you're probably one of them)."

It reminds me of the Calvinism sect of Christianity. They believed in predestination for salvation: God has always known who be a good person and deserve salvation. So there was no point in trying to be virtuous, because the outcome was set before you were born. Still, Calvinists often adopted public shows of virtue, like meticulous gardens, to convince others they were part of the "to be saved" group.

Five plus years ago I wrote a chrome extension that was like an RSS feed for people on HN (still works).

Basically, you followed users and it would create a "news feed" which would show posts from users and comments (with links to context). It would also highlight interesting comments from those users on pages I visit. Similarly, I could block users. Let's me follow people I find interesting. Looks very similar and with some tweaks could be public.
> But living in a walking city with a car is even nicer!

Not necessarily, because it is significantly more expensive (depending on how you implement it). But one way to get people off their cars and onto public transport could be make people pay for their cars. Nowadays, people do pay quite a lot for their cars (insurance, registration fees, vehicle tax, etc), but the payments pale in comparison to the overall costs of having cars as a primary mean of mobility. Putting that cost burden onto the people that produce those costs would lead to many people reconsidering their need for a car.

After looking at this a bit more, here's something interesting. First, it's a very physical model, treating cells as 3D entities with 2D interactions (cell surfaces), and they use their measured binding constants (essentially a measure of protein-protein stickiness across all their proteins) as a key parameter, along with measures of protein expression in various immune system cell types. They're classified into: CD4 T cells, Helper CD4 T cells, Natural killer cells, CD8 T cells, Dendritic cells, Monocytes, Regulatory T cells, B cells. This is all quite complex, here's a simplified 6 min overview of some of their roles, note the importance of receptor-receptor interactions at every stage:

https://www.youtube.com/watch?v=6eMh0Vpyoik

For a nice visualization of immune cells attacking cancer cells:

https://www.youtube.com/watch?v=K09xzIQ8zsg

So, this is a complex dynamic network, and a key feature of such networks is that a change at one point in the network can percolate across the entire network, which can be critical to their normal functioning, as well a play roles in failure /pathology. The ability to model such casading effects could be game-changing in terms of developing treatments such as targeting cancer cells, blocking autoimmune activation, etc. From supplement:

> "Another direct test of the predictive power of this model would be to experimentally block specific cell-surface protein interactions (such as by adding recombinant ligands that competitively inhibit their receptors’ interactions) and
gauge how cell-to-cell contact frequencies change. If these changes are predictable from our “ground-up” mass action kinetics model, that would demonstrate the utility of our systematic approach."

Let’s say I could easily replace the battery in my old iPhone 4s. What good would it do me when none of the cellular carriers support it?

My Apple Watch 3rd Gen also has a cell phone chip that one day will be obsolete. While the cellular version of the 3rd Gen Watch has 16GB of memory, the non cell version has 8GB and is already struggling with operating system updates.

As far as AirPods, if you have seen the tear down, it’s mostly a huge battery. Throwing away the battery and keeping the rest wouldn’t cut down on ewaste meaningfully even at scale.

Even if I could replace the battery of an x86 Mac easily, why would I want a laptop that sounds like a freight train when I open a few Chrome tabs, gets hot, has horrible battery life and is still slower than an M1 MacBook Air for $999 that beats it on all measures?

But let’s get back to the Garmin GPS watch example. Have you seen how big and bulky those things are compared to an Apple Watch. Do you think I would want to use that in 2022? I had to use a separate chest band to measure my heart rate. Now it’s built into the watch.
I really like this. One peculiarity about HN culture I found is that commenters will often comment something tangental to the subject of the post, so I often find myself reading really insightful comments on threads I otherwise have zero interest in.

Articles about procrastination always fall into a "work when you don't feel like working" catch-22 that makes them hard to take seriously.

I didn't cure my procrastination until I internalized a sense of professionalism. I go to work like everyone else who goes to work. When I'm at work I have an obligation to my employer, my family, and myself to do what I'm supposed to do as well as I can. This also makes it easy to indulge in what I want when I'm off the clock.

If you can't get started, at least try and avoid distractions during your "professional" time. You can work or you can do nothing. That is typically uncomfortable enough to gain some forward momentum on a project.
> If the process is expensive, it will only be available to rich people.

I have trouble believing it will remain expensive unless there is a cultural taboo against it.

In general, once proven out, there should be pretty high demand for the tech - and that provides a lot of opportunity for profit for whomever can get the costs down.

What looks like a bigger blocker to me - AFAIK, IVF is really harsh on the body isn't it? Lots of hormones to force out a lot of eggs. That looks like the real adoption bottleneck to me.

$4,200 is _very_ optimistic for the panel/battery cost for a 30kWh system. The GP comment also conveniently excluded "labor and extra hardware/electronics". There's a lot more that goes into a solar power system (especially one that has to manage batteries) than just slapping the panels on the roof and dropping the batteries off in the garage. Inverters, chargers, grid integration equipment, etc.

I'm also not sure what you mean by "just" labor. You're talking about a critical system, that has the possibility of seriously injuring someone (including folks outside your house) or causing extensive property damage if not installed correctly. That seems like a thing where skilled (and fairly compensated) installers and some degree of regulation is very appropriate.
It's not a leap at all. If you are knowledgeable in advertising you wouldn't spend the time for such erratic behaviour, for various reasons. For instance, you can't see the overlap of people who work on the OSS code and those making the buying decisions for the commercial product.

BTW, it doesn't come "at zero cost" as you say. You are skewing a very important data point in advertising, the first touch point in the customer journey.
Yes; my current project

I inherited a codebase where the backend is written in Kotlin (using Micronaut) and the frontend in react

Both the backend and frontend are very clean and i learnt so many new cool things just by reading the code.

The code is so easy to follow and understand, and the architecture is very nice

The frontend's consists of react functional components that are are written in a way that makes them very reusable and configurable; each component can be extensively configured with props, making it very rare to have to create new components

The backend is structured into independent microservices and it is therefore very extendible and the microservices themselves are small and easy to modify

The major difference between Rust and [Zig, C] is that the latter are essentially "cocky macro assemblers".
They derive their semantics from the semantics of the underlying assembly.
Take https://github.com/ziglang/zig/issues/12251 as an example. Several people from the Rust and Haskell community slacked off on twitter about how awful of a language design this is. However, when you think about what the language actually compiles to it makes perfect sense, and is pretty straightforward.

Rust has the goal of putting as much smartness between what you type and what the compiler produces, which is a perfectly fine goal, but without a specification for the input semantics it's a pretty wobbly thing, especially for a systems programming language. A lot of bit packing code is simply not writable in rust today without immediately invoking UB, that works for now but might break with every bugfix release.
Yes, sorry. I meant it to be illustrative of many of them being out there and influencing one another. I'm not sure I could put together a definitive list in the scope of an HN comment. vc was definitely worth mentioning, so thanks for bringing it up.
ICE cars pollute the local environment, which is worse imho than their contribution to global warming. ICE cars are noisy, stink, and have unhealthy exhaust. For those reasons alone, an electric car is better.
