Attached to: UK's First Rapid-Charging Battery Train Ready For Boarding
Did a bit more research, turns out, these trains were originally built by Vivarail (using Hoppecke NMC battery tech) before being acquired by GWR.
LFP batteries aren't able to charge as fast, especially under 5 minutes using an enormous 2 MW (2000 kW) charger.
For comparison:
* A Tesla Supercharger V3: 250 kW
* A modern electric bus with LFP: 300-450 kW
So the GWR train is charging at 5x the power of a modern fast-charging bus, and 8x a Tesla.
LFP charges at a slower pace, is a lot heavier, and has lower energy and power density, and more sensitive to cold weather.

Moderated as "troll" and "off-topic", really?
"Redundant" perhaps, but my comment is entirely on-topic and not being a troll or insulting anyone
.
After some research, found out some of what I knew is outdated, especially regarding types of lithium technology.

False - these trains don't use low energy density LFP batteries like buses, or some EVs. It still uses the tried an tested NMC modules. However, I'm aware of more recent battery-operated train projects using LFP.
To change these older GWR trains (originally vivarail) to LFP would not only add considerable weight, due to many more cells, but the entire electronics and cooling systems needs to be changed, and not to mention, LFP performs worse than NMC in cold weather, and takes longer to charge.
It turns out these trains use regenerative braking and since it's designed not to drain completely, it should last around 8-10 years.
But I accept, some of my understanding is dated, especially if we are able to move to sodium-based battery tech..

Seems really bad idea to use batteries in trains (and transportation with huge battery packs), not only due to extreme weather and cold spells which shorten battery life, but the constant daily charge/drain cycles multiple times a day will just kill the battery capacity more quickly.
Add to that, lithium batteries use what limited amount of lithium, manganese, cobalt, nickel, etc that we have available in the earth, and accelerating mining not only damages the earth, but uses a lot of clean finite water we have available, and potentially adds to slave labour in places like Congo and causes disastrous emissions in various mining regions.

I never understand why people like comments like this, almost like a hit and run.
No substance, no engagement, nothing constructive, just hit and run.

I agree.
Perhaps the AI tools the Ruby on Rails creator was using are not as well designed for a language which has been described as "not a serious programming language"?
Worse still, it's one of the lower ranked languages, even lower than Assembly, Cobol, and even classic Visual Basic!
So I'm left wondering, is their opinion worth listening to, especially considering Linus Torvalds is dabbling in using AI? hmm

Attached to: Microsoft's Risky Bet That Windows Can Become The Platform for AI Agents
Not sure I agree that "Microsoft has been holding back PC growth".
Rather many more arguments could be made that PC/laptop growth exploded due to Microsoft's ease-of-use OS's over the past 3 decades along with their MS Office offerings and DirectX-based games which have grown massively over that time frame in advancements. It could also be argued that Microsoft has helped push Linux advancements as they have been one of the top contributors to the code since 2010, initially with Hyper-V drivers, then security and other kernel advancements especially in virtualisation.
Regardless, if memory becomes unaffordable and unattainable by the masses, then the *personal* computer starts dying, and it doesn't matter which OS would be dominant when we're all using thin-clients connected to some sort of cloud-based OS for our computing needs, whether it's gaming or productivity.

I don't envision AI agents in OS, but rather helpful agents within apps to automated various tasks, such as data analysis, summaries, etc.
But as memory prices keep going up and the scarcity increases, I do envision the end of the PC era and the boom of thin-clients all working in a virtual OS in the cloud - no doubt, the dream of the WEF as well as world governments to keep their citizens under check.
"Welcome to 2030. I own nothing, have no privacy, and life has never been better" - WEF.

Attached to: Airlines Cancel Hundreds of Flights After U.S. Attack on Venezuela
Clearly you've never travelled to non-western nations, as yes, there are countless fishermen who start small with a small wooden/skiff boats / dugout canoes powered only by a little engine, and if lucky, with a faster speedboat-like engine.
It's only when there is a family or friends involved do they upsize to a slightly larger boat. Many others rent the larger boats.
Going out at night to fish without lights is common to not startle certain types of fish, while others may do so to avoid licensing costs, or for calmer waters and less competition.
The presence of a motor, high speed, or nighttime operation is not proof of guilt, nor are a few grainy photos of boats.

Indeed.
State terrorism.
Only 2 nations can get away with mass murder and state terrorism: USA and the zionist regime.
Imagine Iran kidnapping Trump / Biden.

An anonymous reader writes: PBS NewsHour has a segment on the escalating AI battle in health insurance claims. A 2025 survey found 71% of health insurers admit to using AI for utilization management—the process that approves or denies claims. Of the 73 million Americans on ACA plans who had in-network claims denied, and less than 1% appealed. Now patients are fighting back with AI of their own. Free, open-source tools like Fight Health Insurance and the free Counterforce Health let patients upload denial letters and generate customized appeals citing relevant regulations and medical necessity arguments. Indiana University law professor Jennifer Oliva warns this is becoming an arms race: "As consumers become more empowered by these tools to fight back, the insurers will just up the ante." She also raises a darker concern—insurers may be using AI to identify patients unlikely to appeal or who "will not live through an appeal based on the time that the appeals take." Current regulation is nearly nonexistent.
