avsteele··on Gleam 1.2.0 release – Fault tolerant Gleam
Interesting language. Great web page.

I find it off-putting to have politics as the third thing on the home page though. Makes me think there is going to be a scissor that cuts the community apart at some point.

("As a Gleam community, we need to have a position on Israel-Palestine!")

avsteele··on Testing quantised inertia on Proxima Centauri
I wish he spent a bit more time on the section regarding magnitude of the effect for different accelerations.

If indeed there is a minimum acceleration I wonder if it might not be measurable with some atomic physics experiment (atomic clock, etc..) in space a bit away from earth.

avsteele··on Colorless green DNNs sleep furiously in an unexplainable fantasy
Exactly.

I'm very surprised someone a whole essay like this and have this misconception.

I was half expecting to see "humans building something smarter than human machines violates the laws of thermodynamics" next.

This is a little toy model of what goes on inside our ion source, laser cooling + photoionization. I use it in talks sometimes. The colormap is red=hot, blue=cold, white=ions

avsteele··on Novel attack against virtually all VPN apps neuters their entire purpose
So every company who uses VPNs to allow their people to get into the network from offsite (customer site, airport, hotel) now can't safely?

You basically have to trust everyone on the remote LAN to not act like a malicious DHCP server.

Reading the other thread, this wouldn't even be just the gateway.. Sounds bad!

avsteele··on Phone conversations with law enforcement can be recorded without their consent
Readers please note: recording consent laws vary state to state. Do not read the headline and assume it applies to yours.

Some states are single party consent, some two, some might be more subtle.

avsteele··on Xz: A microcosm of the interactions in open source projects
It is trivially easy for those types of actors to simply use a stolen identity or create an entirely plausible one out of thin air.

Can you provide a historical example of when something like that has happened?

It sounds like hyperbole to say that it is 'easy' (even for a state) to impersonate a real-life identity or create one for a professional developer with a multi-year work history.

avsteele··on Debian on xz-utils: revert to version that does not contain changes by bad actor
Your point is well-taken, but see my reply below. Stopping state-backed level actors might not be possible, but we can make it harder for cyber-criminals.

Has it been shown this is by a state-level actor?

avsteele··on Debian on xz-utils: revert to version that does not contain changes by bad actor
I am not assigning any personal blame or making an accusation of bad judgement on the maintainer.

Taking contributions from anons appears to be common. I am suggesting that should change.

avsteele··on Debian on xz-utils: revert to version that does not contain changes by bad actor
I would want to think it over but off the top of my head:

GitHub could provide this as a service, perhaps using uploads of whatever state/national ID the user is coming from. Give a little 'verified ID' badge. All banks do things like this for new accounts.

Granted this doesn't stop state-actors, but it should be effective against cyber criminals.

I think a system where it was harder for unknowns/newcomers to contribute but had better security is a good tradeoff. Esp. since it is likely this incident is not unique.

avsteele··on Debian on xz-utils: revert to version that does not contain changes by bad actor
It would appear that no one knows the RL identity of the bad actor? Or even vouches for them?

It doesn't seem wise to accept contributions to projects which may have security implications from anons. Code contributions clearly can't or aren't independently validated.

avsteele··on Doom Captcha (2021)
This is fun. I have been having trouble with Google capchas recently, so Ii;d be happy if more where like this.
avsteele··on Keep your phone number private with Signal usernames
Yes, this drove at least two people I know/encouraged to use it off the platform. When people see this they also think that Signal snooped their contacts. Very bad.
avsteele··on 23andMe is reportedly turning the blame back on its customers
Thank you!
avsteele··on 23andMe is reportedly turning the blame back on its customers
The article is terrible. What are commenters even discussing without having additional context?

   The hackers initially got access to around 14,000 accounts using previously compromised login credentials, but they then used a feature of 23andMe to gain access to almost half of the company's user base, or about 7 million accounts, the company previously told Business Insider. 
This is the only actual 'information' in the article. The rest is just finger pointing. But what does this mean?

What feature? Does 'gain access' here mean all the data you would have as if you logged in as that user? How does 14K become 7M? Is it that case that an average user has access to the data of 500 other users on website? (7M/14K)

avsteele··on Scientists discover 100 to 1000 times more plastics in bottled water
If you are referring to the lead-crime hypothesis That isn't exactly a consensus view.

Putting that aside... I wonder if researchers looking for damage from leaded gasoline for those decades? We have been using these types of plastic for a very long time.

avsteele··on Scientists discover 100 to 1000 times more plastics in bottled water
Researchers don’t yet know how dangerous tiny plastics are for human health. In a large review published in 2019, the World Health Organization said there wasn’t enough firm evidence linking microplastics in water to human health, but described an urgent need for further research

Finding a connection between microplastics and health problems in humans is complicated — there are thousands of types of plastics, and over 10,000 chemicals used to manufacture them. But at a certain point, Mason said, policymakers and the public need to prepare for the possibility that the tiny plastics in the air we breathe, the water we drink and the clothes we wear have serious and dangerous effects.

If the negative effects were very strong they would probably have found evidence in previous studies. There may be something here, but it isn't something worth worrying about much.

avsteele··on Power over fiber
That's fine safety guidance but on the facts this is not correct.

For single and multimode fibers if it has a smaller focal spot some distance the fiber than at its tip you are talking about an assembly that includes the fiber plus an optic.

This is unambiguously true for single mode fibers. Multi mode one will diverge less

I could see there being some exception for a strange fiber which has a multi-emitter output, was nanostructured, tapered, etc..

avsteele··on Power over fiber
What types of fibers are you talking about?
avsteele··on Power over fiber
I can see 780 nm (rubidium laser cooling light) specularly reflected from an index card at maybe 100 mW, if memory serves.
avsteele··on Power over fiber
Guy's name is literally rubidium!
avsteele··on Power over fiber
800 nm (NIR) does present hazards. Most people can't se it until the intensity is very high, so you blink reflex doesn't protect you.

Having said that, it is probably highly divergent out of the fiber (depends on type). There's no risk beyond a few cm. Don't stick the fiber it up against your eye though.

To answer someone below its unlikely you could get burned except right at the fiber tip. You can stick your hand in a 1.5W beam as long as it isn't tightly focused.

avsteele··on Compare Google, Bing, Marginalia, Kagi, Mwmbl, and ChatGPT
I don't think this is a fair criticism.

1) The step where you evaluate "how they perform" is necessarily subjective.

2) you could design a study and recruit participants but that isn't something a blogger is going to do.

3) He does link to polls where people agree with the idea the result have gotten worse. Yeah, there are sampling problems with a poll, but its better than nothing.

In this case especially, the writer is answering the question: "Whose results are best according to my tastes?"

avsteele··on OpenAI suspends ByteDance's account after it used GPT to train its own AI model
OK.

In the case at hand we are dealing with a mathematical function. In->Out is all there is. Back-estimating a mathematical function by sampling is as close to reverse engineering as anything is.

avsteele··on OpenAI suspends ByteDance's account after it used GPT to train its own AI model
The terms against using the output to develop a competing product seem the same as reverse engineering to me.

Competitors can't get OpenAI's model weights but use its outputs to produce a functionally similar model.

It's like if you had a competitor's engine and couldn't open it up but could still see the outputs: torque, rpm, ..., and could control the inputs: fuel intake, air mixture, etc... Then you make an engine by inferring back from these measurements.

Wouldn't that be reverse engineering?

avsteele··on Tinnitus linked to undetected auditory nerve damage
I developed tinnitus during a bout of COVID last week.

On about the third day I had an earache in one ear. Earache went away after about a day but now I have pretty strong tinnitus in that ear. COVID symptoms long gone now but tinnitus remains.

'Volume' is negligible when I wake up but increases over the day. I still feel some 'pressure' in that ear (maybe residual sinus infection?) so I'm hoping it will heal on its own.

Anyone else experience this?

avsteele··on Please ignore the deluge of complete nonsense about Q*
Please point me to an example of his good arguments.

I only see his posts on Twitter but haven't been impressed.
