Well, i can only be cheaper to shift demand to high production hours then building a battery. Especially as you don’t only need an inverter for the battery but also the charger or MPPT to suck up the peak solar power which is only lasts for about 3 hours. So you can save building a lot of excess batteries

Australia is in fact primed to go all-in on all-electric. They have an hyperabundance of solar and wind (+land where it can be installed) and have the purchasing power to buy cheap panels and electric cars from China. Even the mining industry is going electric as it is plainly cheaper to operate mining trucks on solar PV. They couldn’t care less about that strait of hormuz disaster. Energy to cheap to meter at last!

This is one of the killer use cases of AI, build personalized stuff for your life, that no company does. It is kind of generalized „intelligent stuff“ that one can use. Like minecraft your life

Seems like a more general solution to a Tesla API Firewall that i was thinking about. My idea was to use some kind of gateway/firewall LLM to check commands that another agent would send to the Tesla API.

Altman is the startup idea king. He should definitely know his moves. Even worse for antrophic is the renaming from clawd to openclaw. It is almost comical now that Peter had to rename it and now it sounds more like OpenAI

What is especially annoying is the aistor/minio business model, either get the „free“ version or pay about 100k… How about accepting some small dollars and keeping the core concept? However this seems to be the business type of enshitification. Instead of slapping everything with ads, you either pay ridiculous dollars or move on.

Sales fell 4% in North America last year. EV share is more like 20% globally and seeing a YoY increase every year for at least 10 years now.

We are slowly getting there, the used EV market takes time to build up a stockpile of good and fast charging cars. Also for total cost of driving you need to factor in cheaper charging than fueling on average, lower maintenance and maybe reduced (road) taxes depending on the country.

Toll gates in general are a waste of time. I use bip&go + telepass lanes in Italy to get through them faster.

And you can buy them and use them right now, as i can go and shop some solar panels, inverters, batteries, some cables put them about anywhere and just have free electricity after the initial expense?

Solar panels etc. will last decades and can and will be recycled afterwards. Further, most materials needed for renewable energy infrastructure (iron, lithium) are highly abundant on earth. Most of the suppliers work to use cheaper (=more abundant) materials in their products, replacing lithium with sodium in batteries and silver with copper in solar panels. Wind turbine blades are produced now using re-solvable resins.

Being used to European style ski maps, I don’t really understand why you would paint a ski map. A ski map is a map and should convey all the information you need without being overwhelming. I don’t get it why it would show different trees or why the colors need to be natural. A map is a man made thing, nature is outdoors. There is no need to reflect it on the mapy

I appreciate the artwork though.

Good work, but the headlines are still in „newspaper“ style and not in hacker news style

Imho it’s a good thing to not block other countries approach to clean power from a german perspective.

However, there is just no way new nuclear power makes any sense for German grid. Just last week we had negative prices for _every_ day during peak demand (yes, peak demand is usually around noon, it’s just not visible because there is so much solar self-consumption) https://www.energy-charts.info/charts/power/chart.htm?l=en&c...

What‘s really needed is more batteries. At lot more batteries soon.

I‘m currently visiting Paris for the second time in my life after 2008. I can tell you it’s much cleaner now than it has been back then. There are many electric (cargo) bikes, scooters, cars and buses. The city is much quieter and there is way less crazy traffic. There are few cars parked on the side of the street. However these parking spots were cleared for bike lanes and bike sharing parking. Biggest polluter are the garage trucks, which are still diesel and noisy. If they manage to replace them by electric ones, many parts of the city will be really quiet.

Right, there is no measurements involved and most decisions are gut-based. In the end most systems will work somehow, it’s just that the pain points in development are different.

Oh well, it’s not just about microservices… The whole damm IT/software world is just like that. Very few well-defined things, very few good standards, very few agreed upon architectures.

From an electrical engineering background, it is mind-boggling to me how we got to this convoluted software world. It’s like having different electric sockets in the same building. The only hard standards seem to be IP and HTTP.

I just have two basic explanations for that: 1. Most software today has no relationship to physics or the hardware it is running on. Hence, there is no need for optimization. 2. In new projects you always start from scratch and there are few guidelines/truths/principles to hold the developer accountable to. And if there are, then you can always discuss their applicability to your problem.

The biggest danger is trying to recharge them after they have been stored for a long time. The anode and cathode might short-circuit and then a fire will likely start. If you want to check out an old gadget or battery make sure to watch it while charging and have a fire safe container or a plan to extinguish the fire at hand.

Well, i have to say that is one area where Germany actually shines. We shut off the stupid, power-hungry and slow 3G, but kept 2G as a basic service. That was a very good decision. All data comms can switch to 4G/5G, while voice comm can remain on 2G as backup. Low data rate devices can also use 2G/GPRS/EC-GSM.
