xbmcuser··on Heart aerospace completes first flight of largest electric aircraft
This was claimed by CATL chief battery scientist recently or at least that's what the press claimed could be mistranslation from Chinese to English.

Lithium air batteries theoretically can reach 10000-12000w/kg though they have only reached 1200w in labs so far. Gasoline is 13000w/kg. We don't need to match gasoline as it is inefficient. CATL just got it's 500w/kg batteries for commercial aviation approved I am betting China is going to do the same with electric planes that it did with cars. They can't build a efficient enough jet engine to be competitive yet but they already can build the narrow body planes replace the jet engine with electric take over the market for short haul aviation once the battery densities cross 1000w/hr.

90% of the tech worker population does not work for themselves they work for someone that pays them 1000s in salary for those paying those tech worker spending $40-50k on a server that helps them not pay for 2-3 tech workers is not that big a deal.

well this just shows how good the AI is at programming

That is the problem currently the subscription plans are being subsidized by VC money and token buyers. When Open weight get good enough token buyers build their own servers instead of buying tokens then no one to subsidize the subscriptions

Did you guys read the fine print they plan to increase prices significantly in the future
xbmcuser··on Managing AI Coding Costs at Scale
I disagree the worth of software will become a lot less as LLM take hold and more people outside software devs know how to use them properly. I am the default IT manager for our small office as I am the guy most interested in tech and in the last 2-3 years I am getting llm to write python scripts for me to do work that would have cost $100s of dollars. Currently you need to pay $100-1000s for a software with 100s of features while you might actually need 1 or 2 of the features which you can get the llm to write for you.

As the LLM's keep getting better at writing software actual coding skills required will decrease which will result in a huge influx of software crashing prices. You can see this in already in open source projects in the last 6 months to a year Jellyfin had a huge influx of custom clients made by different people for fixing their own itches about the official software.

Deepseek is open weight/source ie it will be running on US servers in the US maybe by on each companies own servers.
xbmcuser··on In China gas engine became a "marketing decoration" for customer's reassurance
Well its one way to solve the range anxiety. How long before they become modular so people only attach them to cars when going on long trips and leave them at home for daily driving.
xbmcuser··on Show HN: Run an 80B Qwen in 4.3 GB of RAM on a Mac, and a 35B on an iPhone
We will see such power and price now only when AI market crashes or China reaches node parity and goes after market share as currently the way they are buying out most of the latest node production the consumer prices will only be palatable to the very rich or we will need to be happy with older slower nodes
xbmcuser··on I stopped trusting USB-C cable labels and started testing them
LTT has created true spec cables with the actual spec mentioned on the cables but they can not keep up with demand despite being expensive get sold out as soon as new stock comes in.

xbmcuser··on US Treasury undertakes historic intervention in yen market
It is not completely but part of the reason Japan wants to defend it's currency is inflation because of increase in energy prices.
xbmcuser··on Plug-in solar is coming. Plug-in batteries should follow
Today, building new solar, wind, and batteries is cheaper than building new coal or gas plants, let alone the fuel costs. Building new coal and gas would actually be stupid. Running older plants without caring about pollution might be cheaper in the short term, but not by much.

And what do you mean by "new technology"? We've had solar power for over 50 years and wind power for centuries. Australia was a pioneer in grid-scale batteries over a decade ago with Tesla.

Even if you wanted to build gas and coal plants, where would you get the turbines? There's a massive shortage, with deliveries supposedly 5 to 7 years away that is even before the current AI based demand surge. Nuclear will also take decades to build. The only fast, cheap option left is solar, wind, and batteries. Which can be up and running in under 12 months.

xbmcuser··on Plug-in solar is coming. Plug-in batteries should follow
it is the same as the balcony solar though so what is the difference the batteries would be doing the same exact thing?
xbmcuser··on Plug-in solar is coming. Plug-in batteries should follow
Yes payback period batteries as at those prices payback period falls below 5 years with just 4-5c arbitrage so even if you don't have solar like most apartments it is still useful. And the price is low enough that it can be made mandatory for all new home construction without inflating home prices.
xbmcuser··on Plug-in solar is coming. Plug-in batteries should follow
The new sodium batteries are a lot safer than the lithium chemistries. And we already do have type of home batteries they are just called UPS systems. The real game changer will be when 3-5kwh plugin batteries fall below $150-200pkwh as at those prices batteries will make sense even for apartment owners/renters with no solar to use it to demand shift as time of day electricity prices get more common.
xbmcuser··on DeepSeek-V4-Flash Update
its an open source model if it is important enough that you have to worry about a new version breaking something then why the fuck was that not running on your own servers this is not an Anthropic or OpenAI closed model that you only have access through an api

Who cares if it is programming correctly I would be more worried about it not doing things like find security bugs because US or Chinese government does not want to. Which LLM is more likely to do that?

xbmcuser··on China is starting to measure EV charging times in seconds, not minutes
it does produce more heat and that has to be dissipated. but the core issue that held back sub-10-minute charging for so long was dendrite formation not energy storage
xbmcuser··on 2x, not 10x: coding with LLMs in 2026
I am not a programmer but for me the return is 100x as I am automating stuff that I knew could be automated but did not know how to but at the same time it was not worth the effort to write it down and pay someone to code it for me. But now I have created so many python and bash scripts that save me hours and hours a month. In my opinion the people that can most take advantage of the programing capabilities are people that least use it for such or know the how they could automate a lot of the repetitive tasks they have to do at work or on their own time.

After capital reaches a certain amount, wealth is no longer about effort. Capital keeps generating more capital. As long as you tax that capital and force it back into the economy, things will be okay. Otherwise, it will destroy the economy. This is a simple math problem that people, even on Hacker News where logic and math are valued, simply ignore. If the pie grows by 5% but 80 to 90% of that growth is captured by a small percentage, they will keep taking more as their capital increases, leaving a smaller share of the pie to be divided among more and more people. Ie the feudal times where most economic output was controlled by a few. The world is fast moving back to those times.

I agree with you. I don't believe pure capitalism or pure socialism works; we need something in between. China is somewhat like that, but because of the type of government it has, it is viewed with a jaundiced eye. Countries exist for their citizens, so things like healthcare, housing, and most infrastructure should be provided or subsidized by the government.
xbmcuser··on I'm 38 and I Can't Support Myself Anymore
I think most people conflate the 2 things the current problems are not just because of capitalism but rather the capture of the government by capitalism.

xbmcuser··on GM Backs Sodium Ion Batteries for U.S. Grid Storage
AT grid scale, sodium quickly closes the gap on lithium. The safety overhead, active cooling, and physical spacing needed to control lithium’s thermal runaway risk eat away most of its energy density advantage. Plus, CATL is hitting cost parity between full sodium BESS and LFP BESS systems.
xbmcuser··on GM Backs Sodium Ion Batteries for U.S. Grid Storage
What bullshit are you spouting sodium batteries are safer and do not have the same thermal runway concern that lithium batteries do.
xbmcuser··on “We have information that Moonshot distilled Fable for the development of K3”
No you should not care unless you are a shareholder in one of these Ai ponzi companies. For the rest of the world Chinese companies matching and open sourcing llm's will keep 100 or so tech oligarchs taking over all the world economic output for themselves as all the idiot politician are unwilling to tax wealth.
