rgmerk··on We're going to need default hard budget caps on pretty much everything
It's the modern equivalent of the Dilbert classic about Goodhart's Law:

rgmerk··on Things that apparently cause cancer
Yawn. Anybody that has looked into the data knows that nuclear is acceptably safe, particularly compared to fossil fuels.

The problem with nuclear is cost, not safety, and thus far it appears intractable in the real world rather than the fantasy world that the likes of BTI inhabit, whereas the problems and limitations of renewable energy are actually being solved.

rgmerk··on Tesla takes on $30B in credit as it approaches unprofitability
They’re two different products and market classes. In many markets you can drive up to a 12-seater on a regular car license.
rgmerk··on Tesla takes on $30B in credit as it approaches unprofitability
Just like an instrument panel and an indicator stalk.

It’s a shame, because even after all these years Teslas are still state of the art in quite a few aspects (their packaging and drivetrain efficiency, among others). But here in Oz where we have a smorgasbord of cheap and excellent Chinese EVs, there are better options unless you want FSD above all else.

rgmerk··on Tesla takes on $30B in credit as it approaches unprofitability
Sure, but if they're losing money, you go looking for ways to make a bit more money without having to spend too much. My contention is at least some of these things could be done relatively cheaply and would generate additional sales.

Tesla may be getting belted from pillar to post elsewhere in the world by the Chinese but they a) still have a near-monopoly in EVs in the US, and b) have a cost-competitive EV manufacturing operation in China from which they can supply other parts of the world.

That still doesn't help their image problem, which is still very real for many left-leaning affluent consumers around the world, but that's less of a problem for commercial vehicles.

rgmerk··on Tesla takes on $30B in credit as it approaches unprofitability
Look, I get that Elon wants to chase AI, but why not do relatively simple, low-cost things like build a proper 7-seat SUV that uses the Cybertruck platform - or even a properly stretched Model Y platform (rather than the six-seater L)? Or how about a delivery van on a stretched Y platform?

Tesla's product line is narrow and aging rapidly.

rgmerk··on Italian parliament votes for return to nuclear energy
To add to this, China’s overall greenhouse gas emissions have been flat or declining for a couple of years now: https://www.carbonbrief.org/analysis-chinas-co2-emissions-ha...
rgmerk··on Italian parliament votes for return to nuclear energy
That’s just not true.

An energy source with an EROI of 20 but which requires thousands of highly skilled people to tend it is going to lose to an energy source with an EROI of 15 that sits in a field and just works for 30 years.

rgmerk··on Nvidia is the central bank of AI
Maybe I’m just old and cynical but that sounds like the kind of assumption of independence of events that led to the GFC .
rgmerk··on Commercially Available Bike Generators Are Not Sustainable (2011)
I would too...but an off-grid solar and battery setup sufficient to run the induction stove and microwave is still well into four figures - cheap for a developed country resident who wants some basic comforts in their wilderness lodge, but still well out of reach for a subsistence farmer in the poorest parts of the world.
rgmerk··on Commercially Available Bike Generators Are Not Sustainable (2011)
This arguably had some relevance in 2011. In 2026, cheap solar and batteries make human-powered static devices that would benefit from the extra power of a stationary cyclist completely redundant.
rgmerk··on Commercially Available Bike Generators Are Not Sustainable (2011)
Not to mention they’re talking about lead-acid batteries, which have been replaced for pretty much every application, except (for now) starter motor batteries for combustion vehicles, by the various lithium batteries.
rgmerk··on California lawmakers unanimously pass Linux exemption from age-verification law
Non-commercial projects and individuals can do bad stuff too.

I agree the bar is a lot higher for those projects than massive corporations, but I think it's a pretty arguable case that "people are using 3D printers to make guns with features that would otherwise be illegal, and they are being used in crimes in some number" clears that bar.

rgmerk··on California lawmakers unanimously pass Linux exemption from age-verification law
A quick search suggests that 3D-printed guns being used in crime is an actual, for-real, and growing problem.

I take it that you wouldn't be OK with somebody building a uranium enrichment facility in their backyard for their hobby reactor. So there is a line to be drawn on where people's freedom to tinker ends; it's just a question of where you draw it.

Personally, I think given there is an actual documented, non-isolated problem with 3D printed guns being used for violent crime, there's a debate to be had that's more sophisticated than "REGULATION BAD".

rgmerk··on Show HN: OpenTIE and OpenXWA, Modern Ports of Tie Fighter and X-Wing Alliance
Amazing games. It'll be fun to give this a spin some time.
rgmerk··on The turbulent AI era is here
Gates was a ruthless businessman who fought his way to a couple of monopolies and would have happily had a lot more if he could.
rgmerk··on FDA clears blood test to aid evaluation for Alzheimer's disease
That's awesome that medical science is making a big difference for your family member.

I suppose my point on "are we there yet?" is that the benefit of knowing is limited when there aren't any preventative treatments you can take. I can see both sides but I'm not sure I'd want to take such a test.

rgmerk··on FDA clears blood test to aid evaluation for Alzheimer's disease
Not a doctor or medical scientist, but my understanding is a) the effectiveness of those anti-amyloid drugs as a preventative tool is unclear, and b) they have a pretty scary safety profile.

Clearly the goal is to be able to prevent the disease from progressing or slow it significantly, but are we really there yet even if we have a test?

rgmerk··on CFTC declares market emergency, orders Kalshi to continue to operate in New York
In Australia, where legal online sports betting is everywhere, it's hugely unpopular with everyone except the bookmakers, TV networks (for whom betting ads during sports broadcasts are the one remaining decent revenue stream), a relatively small group of gamblers (many of whom gamble enough for it to pose serious problems for them and their families), and the nominally socially-democratic politicians running the federal government (who were more than happy to ban social media for teens despite the evidence being ambiguous at best, but are amazingly reluctant to tackle this, despite the demonstrated harm).

Put the genie back in the bottle and ban online sports betting. If somebody wants to place a bet on sport, make them physically go to a betting shop or the racetrack.

rgmerk··on CFTC declares market emergency, orders Kalshi to continue to operate in New York
In other parts of the world, betting exchanges like BetFair operate this way, but unlike Kalshi, there's no pretence that what's occurring is anything other than gambling, and they are heavily regulated like other sports betting operators.
rgmerk··on CFTC declares market emergency, orders Kalshi to continue to operate in New York
The US SCOTUS is the single best argument against putting too much into a written constitution.
rgmerk··on CFTC declares market emergency, orders Kalshi to continue to operate in New York
I'm with the state of NY on the merits here. They're basically BetFair, and they should be subject to regulation like it.
rgmerk··on Amazon backs power plant that may become top source of US climate pollution
Cite your sources. While there have been cost increases in offshore wind projects in recent years, they remain well under nuclear costs as far as I’ve been able to find.

I’d add that any new nuclear projects, if anyone is courageous enough to attempt them, are likely to face similar cost increases because many of the same factors apply to them.

rgmerk··on Amazon backs power plant that may become top source of US climate pollution
I've no doubt that fusion will be solved, technically.

I am hugely skeptical that it will be solved economically given that it suffers from many of the problems currently pricing coal and nuclear out of the market.

rgmerk··on Amazon backs power plant that may become top source of US climate pollution
Nuclear reactors across the US and Europe have been a complete project management omnishambles and consequently have been massively costly and massively late.

SMRs are vapourware and are similarly economically uncompetitive.

Just build solar, wind, and batteries, and we'll worry about solving for the last 15% of electricity demand when that is actually a live problem (for which there are solutions that don't involve nuclear power and don't rely on magic beans being invented).

rgmerk··on Windows 11's built-in Weather app wastes more than 1 GB of RAM
It will be interesting to see whether OS and application developers start to face commercial pressure to debloat their applications.

For operating systems and their bundled applications, Apple's integration is an advantage here; the OS designers work for the hardware company and have aligned incentives. That doesn't mean they necessarily align with their customers, just that they are internally aligned.

Microsoft...do they even care about the snappiness of Windows desktops any more?

rgmerk··on Amazon Is Creating the Biggest Pollution Source in the Country
Some thoughts:

* you can run data centres on grid electricity, which can come from mostly-renewable sources (in short, you need gas mainly as as an occasional backup).

* running things off-grid is dumb, and they’re only doing it because they’re desperate to get their data centres up and running yesterday so that they’re the ones who get to the singularity first (or some approximation thereof).

* the US electricity grid is f**d, mostly for the same reasons you can’t build any linear infrastructure in the United States - too many bodies hold veto powers and use any such infrastructure as an extortion opportunity.

* The spike in gas-powered generation for data centres is essentially a US phenomenon. Globally, the vast majority of new electricity supply is coming from renewables.

* in a sane world, Amazon and new large-scale data centre providers would face punitive carbon charges to incentivise them to switch to mostly renewables as soon as possible.

rgmerk··on 2027 memory capacity is reportedly sold out
I’ve no doubt they’re setting up memory-footprint auditing agents as we speak.
rgmerk··on 2027 memory capacity is reportedly sold out
I dunno, a RAM expansion on my Commodore 64 Ultimate might let it open bigger documents in GEOS…
rgmerk··on CP/M-386 – CP/M for 386 protected mode, derived from CP/M‑68K
I was a kid at the time, so I only got as far as writing and modifying a few programs in MBASIC.

Anyone that got anything nontrivial to work on those systems deserves much respect.
