lightedman··on Study: Blue light impairs the eye's ability to distinguish fine detail most
That birefringence in corundum is why fluorite is used. Fluorite lenses low index of refraction across all wavelengths is also the reason for lacking chromatic aberration.

Fluorite lenses are generally superior. For macro photography there is literally no equivalent.

lightedman··on Smartphone LED detects hidden cameras with AI
Depends on how cheap you go - most of the cheap ones that take images where the blacks look grey likely do not have an IR filter on them. Most quality phones will use a camera with IR filters on them - blacks look like blacks.

"On a related note, anyone wearing prescription glasses will be affected by chromatic aberration to some degree"

Fluorite lenses FTW. Practically zero aberration. CR-58 pales in comparison.

lightedman··on Barrier lake continues to pose flood risk, China warns
As a studying geologist, I find such a simplistic reduction to be very absurd, there are many factors which influence how that released energy causes its damage. Are there physical impediments in the way? Are there breaks in the path of flow? Is the environment already used to this amount of water flowing through it suddenly (the evidence of life everywhere says no so no surprise a ton of life gets lost when it suddenly blows through.)

Such a simplistic reduction also does serious disservice to the structural geologists, soil analyst techs, and others in the geological profession whose work focuses on preventing exactly this sort of situation. It's more complex than "Volume and speed."

lightedman··on Barrier lake continues to pose flood risk, China warns
This lake is currently halting any further rescue operations in the area, because the collapse of it threatens to unleash yet another very devastating flood.

As these natural glacial reservoirs have no usual natural outlet, when they go, that's thousands of years of stored water and energy released. Anything that catches it now has those forces to contend with, and freshly-created lakes tend to not hold up very well to being constantly filled while attempting to settle into a stable configuration.

That unfortunately means we have to give up on the people caught in the first flood, as the potential for a second one catching the rescue workers is too great.

Horrible incident. The best we can hope for from this is a greater understanding of the risks associated with living in such an area, and hopefully better geological warning systems will be created out of this.

EDIT: For perspective, the energy released in this event, capable of causing a 5.2 magnitude seismic event to register, would have been equivalent to roughly 30 of the nukes we dropped on Hiroshima and Nagasaki.

lightedman··on Some conservationists are helping to restore Africa’s wild dog populations
We're in the era of 4k and 8k monitors. That character limit only occupies a tiny fraction of any modern screen.

So odd a site dedicated to future technology companies isn't even caught up with modern display techniques, let alone ones that existed some 2 decades ago.

lightedman··on Landsat 9 pass captured the effects of yesterday's catastrophic glacier collapse
The sheer amount of land mass that moved triggered seismometers all over the place. One seismometer registered a 5.2M. To put this in perspective, on the surface of the earth, quake energy does not travel very well. For this to make a seismometer register that high would require an absolutely terrifying massive amount of land to be moving on the surface.

Current estimates are the slide itself was roughly half a mile wide. That's absolutely massive.

lightedman··on Actinide is first startup to produce high-assay low-enriched uranium (HALEU)
"Uranium-235 isn't useful for dirty bombs"

It is when your goal is to throw a ton of alpha emitters into the environment for the population to ingest. Do you remember your nuclear cookie thought experiment?

lightedman··on Taylor Farms: How One Company's Reach Became a National Risk
"That's a fine way to get fresh food, but if you think the people selling lettuce at farmers markets or farm stands have any verified food safety or food handling expertise, they don't."

They most certainly do at my farmer's market, and every vendor has their certification posted for all to see, along with a health inspector rating underneath it.

lightedman··on Dolly Parton has died
"Her memorial service will need to be held in a football stadium to handle the number of people who want to pay their last respects"

Way bigger. Dolly was beloved by millions, if not billions of people worldwide.

You'd need an area the size of Tennessee itself for the memorial service.

lightedman··on Bomb fishing is wreaking havoc on Indonesia's coral reefs
Which sort of net casting? I grew up with a hand-case 8ft diameter net. I'll guarantee you that's a billion times more sustainable than a trawler.
lightedman··on US data centers tripled annual water consumption to 17B gallons
"Meanwhile LLMs aren't that easy to replace"

A BBS chatbot from the 80s (LISA) was almost as good as modern LLMs and that was just based on key words.

So, uh, yea, chatbots are very, VERY easy to replace.

lightedman··on US data centers tripled annual water consumption to 17B gallons
In fact many humans need meat because the proper plant protein simply cannot grow/exist in their area.

This is why we evolved to be omnivores. Basic biology laughs at your poorly-researched position.

If what you say is true a report to ISO themselves will strip their certifications away and make them toxic to other businesses.
lightedman··on The Mystery of Dark Oxygen
"Read it later. If you can't read it at work, you can read it on your phone or after work from another computer."

Negative, as I have ZERO TIME when working with things involving security.

"Please don't use uppercase for emphasis. Instead, put asterisks around it and it will get italicized."

Yea, no. See your asterisks didn't italicize. I'm looking at your comment right now, with screencap in clipboard buffer if you need a pasted proof of this formatting not working - https://imgur.com/a/7TzQOKw - No italics there. Unless the > at the beginning indicates (stupidly) to ignore formatting rules placed after it, your comment has zero formatting outside of regular spacing.

But you see, I was already aware that function didn't work reliably. Which is why I will continue to use caps for emphasis as it's guaranteed to work.

lightedman··on How I came to write that paper with Leslie Lamport
'How' is one of the most important conjunctive adverbs in the English language, and HN filters it out?

I'm just going to call that exactly as I see it - send the people writing these filtering rules back to middle school so they can learn basic English.

lightedman··on A 25-year-old video patent just expired, ending a legal headache for Linux
It would be with the decoder, as the issue will happen in Windows Media Player but not VLC (which has its own implementation of XviD/DivX.)

I can potentially know if you're home or not and then rob the fuck out of you or kidnap your family members, for one.
lightedman··on The A.I. In Google's New Pixel 11 Is Not Helpful
"I trust Gemini API because they already have all my data"

You trust someone because they already stole from everyone and spied on everyone?

"I despise small tasks like this, so I never really do them until forced."

I hope that isn't how you do your job.

lightedman··on A 25-year-old video patent just expired, ending a legal headache for Linux
"DivX and XviD both encode to MPEG-4 ASP which has a lot of shortcomings that manifestly result in the infamous sludgy green-purple banding artefacts of the time, no matter how good the chosen encoder is."

That's the fault of your decoder; I never had that problem playing DivX or XviD videos in VLC.

lightedman··on Devices with GrapheneOS support should be available in 2027
The real fix would be to bring back physical control buttons and leave the touchscreen for the rest.

Also, I have 6GB of RAM in my phone - switching from a browser to youtube, or vice-versa, should not cause the other to clear and start back again from a freshly-loaded state.

350,000 a year and people can't even get basic things to operate properly. Google needs broken up and their engineers need to go back to the 90s and learn some real programming skill.

lightedman··on Sticky wage norms and the real wage cost of unexpected inflation
Well, for a while, the USA was probably THE premier country for electronics and IT. As a natural result, companies offer top dollar for top talent.

Now days, companies offer top dollar for Junior-level AI talent. And you see where that's going.

lightedman··on Buyer cancels showing after Deflock shows two cameras utilized by the HOA
Single municipality? No. Learn what the Wonderlic score is and how it was used in the 80s and 90s. Police departments used to have an IQ cap of 110 (about 27 on the Wonderlic score scale) and would not hire applicants with higher Wonderlic scores.

Try again - you're arguing with someone that's been in court over this.

"that's not true; it's an Internet urban myth."

Jordan vs City of New London, year 2000, US 2nd Circuit Court of Appeals - try again.

lightedman··on Apple's App Tracking Transparency treated its own apps better than rivals
"He who creates the operating system creates the terms for that system"

Not if it runs afoul of the law, and I can point out several DOZEN ways Apple's developer T&C violates the law.

Apple needs to get slapped down for anticompetitive practices, first and foremost. After that, they need to be removed from the economy the rest of the way for their constant decades of lying about Apple 'security.' (Remember the "Macs don't get viruses" advertising scheme, despite several viruses for Mac existing and being in the wild at that time?)

Tim Cook himself needs to sit in a prison cell for a while.

Police already can't do their job because we select for sub-90 IQ cops.

Giving idiot cops abusable tools is PURE AND UTTER STUPIDITY. If you think otherwise, I can't wait for those same idiots to kick in your door despite you having done nothing wrong due to some false accusation by a clanker and show you the error of your mistaken train of thought.

"I just don't buy it."

Literally there are ARRESTS AND CHARGES against these cops and you 'just don't buy it.'

Do you see what's wrong with your statement? You're being 100% disingenuous.

lightedman··on A controversial Alzheimer's surgery is said to reverse symptoms
No, you lie and provide nothing to this conversation.

Literally in the article which you clearly only skimmed and did not READ "Hong is now running his own trial in South Korea and says that he is finding the same spectacular gains in some individuals, although not in everyone."

That's very much mixed results.
