- I paid for a device with a properly licensed hdmi port. It runs linux. So patent exhaustion applies, at least in the US. I can say ignore the patents to make my property work.
- I have no relationship to the HDMI people. (Never entered into a contract with them.)
- The links to the spec are here. (Trade secrets/nda no longer apply. This is the problem with using trade secrets to protect your stuff.)
- If I point a coding assistant (assume open weights/source) at this thread, and a copy of linux main, it can probably just fix the damn driver.
- I could probably publish my patch with a big fat “only for use with licensed hdmi hardware, not for resale” disclaimer on it.
At that point, what law would I have broken?

I’m all for limited liability corporations, but if there is a smoking gun that shows you intentionally engaged in criminal activity, that should pierce the liability shield.
The confusion around this law is quite frustrating, though. Quite a few customers think they're entitled to not just prices on tags that haven't been updated, but prices for what are clearly entirely different products.
If not, there’s an obvious loophole here. Misprice intentionally, then stop purchasing the item from your distributor if you get called on it, rotating in some similar thing. Later, bring it back with a different sku, or mispriced at some other level.
This would work well for dollar stores, which are optimized to spread in / sustain food/retail deserts.
The store is often literally the only option in town. The wouldn’t even need to sell excess warehouse inventory at the advertised price, since they could just shift supply to another state (or county/store, depending on how poorly the law is worded).
Ideally? Sure.
But when someone can generate plausible disaster photos of every inch of every line of a country's rail network in mere minutes? And as soon as your inspection finishes, they do it again?
If I were working for the train line, and bridges kept “blowing up” like this, I’d probably install a bunch of cameras and try to arrange the shots to be aesthetically pleasing, then open the network to the public.
The runbook would involve checking continuity sensors in the rail, and issuing random pan/tilt commands to the camera.
From the article:
Trains were halted after a suspected AI-generated picture that seemed to show major damage to a bridge appeared on social media following an earthquake.
... Railway expert Tony Miles said due to the timing of the incident, very few passengers will have been impacted by the hoax as the services passing through at that time were primarily freight and sleeper trains.
"They generally go slow so as not to disturb the passengers trying to sleep - this means they have a bit of leeway to go faster and make up time if they encounter a delay," he said.
"It's more the fact that Network Rail will have had to mobilise a team to go and check the bridge which could impact their work for days."
Standard responsible rail maintainance is to investigate rail integrity following heavy rains, earthquakes, etc.A fake image of a stone bridge with fallen parapets prompts the same response as a phone call about a fallen stone from a bridge or (ideally !!) just the earthquake itself - send out a hi-railer for a track inspection.
The larger story here (be it the UK, the US, or AU) is track inspections .. manned or unmanned?
Currently on HN: Railroads will be allowed to reduce inspections and rely more on technology (US) https://news.ycombinator.com/item?id=46177550
https://apnews.com/article/automated-railroad-track-inspecti...
on the decision to veer toward unmanned inspections that rely upon lidar, gauge measures, crack vibration sensing etc.
Personally I veer toward manned patrols with state of the art instrumentation - for the rail I'm familiar with there are things that can happen with ballast that are best picked up by a human, for now.
Having said that, if it was 2020 and you told me that making photorealistic pictures of broken bridges was harder than spoofing the signals I just described, I’d say you were crazy.
The idea that a kid could do this would have seen even less plausible (that’s not to say a kid did it, just that they could have).
Anyway, since recently-intractable things are now trivial, runbooks for hoax responses need to be updated, apparently.
(I just had my first shingles vaccine 2 weeks ago)
There are multiple causes for dementia. If I read figure 2 right, the vaccine slightly reduces the chance of mild cognitive impairment, but cuts the chances of dying from dementia by about a third(!)
Also interesting: The vaccine helps at different phases of disease progression.
The simplest explanation is that dementia is due to cumulative damage, not a single event, and that getting shingles is a big hit.
The vaccine probably prevents dementia in the same way staying out of planes makes you invulnerable to parachute failures.
Trump’s campaign promises were all of the form “X is so bad it will destroy the country and I will fix X”!
Replace X with some problem that Biden had already fixed (factory investment, crime rate reduction, getting inflation under control after the previous president printed money for 4 yeara, etc, etc).
