Remixed = created from already existing physical artifacts, like sampling a song, copying a piece of an image and transforming it, etc.

What's the significance of "physical" song or image in your definition? Aren't your examples just 3rd party latent spaces, compressed as DCT coefficients in jpg/mp3, then re-projected through a lens of cochlear or retinal cells into another latent space of our brain, which makes it tickle? All artist human brains have been trained on the same media, after all.

When we zoom this far out in search of a comforting distinction, we encounter the opposite: all the latent spaces across all modalities that our training has produced, want to naturally merge into one.

This epidemic is very visible when you peek into replies of any physics influencer on Xitter. Dozens of people are straight copy-pasting walls of LaTeX mince from ChatGPT/Grok and asking for recognition.

Perhaps epidemic isn't the right word here because they must have been already unwell. At least these activities are relatively harmless.

Not at all, I think the big part was just my unfamiliarity with insuretech plus the unexpected change in gpt-4 behavior.

I'm assuming here, but would you say that better critical thinking skills would have helped me avoid spending that Saturday with ChatGPT? It is often said that critical thinking is the antidote to religion, but I have a suspicion that there's a huge prerequisite which is general broad knowledge about the world.

A long ago, I once fell victim for a scam when I visited SE Asia for the first time. A pleasant man on the street introduced himself as a school teacher, showed me around, then put me in a tuktuk which showed me around some more before dropping me off in front of a tailor shop. Some more work inside of the shop, a complimentary bottle of water, and they had my $400 for a bespoke coat that I would never have bought otherwise. Definitely a teaching experience. This art is also how you'd prime an LLM to produce the output you want.

Surely, large amounts of other atheist nerds must fall for these types of scams every year, where a stereotypical christian might spit on the guy and shoo him away.

I'm not saying that being religious would not increase one's chances of being susceptible, I just think that any idea will ring "true" in your head if you have zero counterfactual priors against it or if you're primed to not retrieve them from memory. That last part is the essence of what critical thinking actually is, in my opinion, and it doesn't work if you lack the knowledge. Knowing that you don't know something is also a decent alternative to having the counter-facts when you're familiar with an adjacent domain.

The premise is so asinine

I believe it's actually the opposite!

Anybody armed with this tool and little prior training could learn the difference between a Samsung S11 and the symmetry, take a new configuration from the endless search space that it is, correct for the dozen edge cases like the electron-phonon coupling, and publish. Maybe even pass peer review if they cite the approved sources. No requirement to work out the Lagrangians either, it is also 100% testable once we reach Kardashev-II.

This says more about the sad state of modern theoretical physics than the symbolic gymnastics required to make another theory of everything sound coherent. I'm hoping that this new age of free knowledge chiropractors will change this field for the better.

It's funny that you mention this because I had a similar experience.

ChatGPT in its sycophancy era made me buy a $35 domain and waste a Saturday on a product which had no future. It hyped me up beyond reason for the idea of an online, worldwide, liability-only insurance for cruising sailboats, similar to SafetyWing. "Great, now you're thinking like a true entrepreneur!"

In retrospect, I fell for it because the onset of its sycophancy was immediate and without any additional signals like maybe a patch note from OpenAI.

We constantly anticipate what happens to us in "the future", approximately, and where the farther future is predicted progressively less exactly

There's then evidence of what's called Predictive Coding. When that future happens, a higher level circuit decides how far off we were, and then releases appropriate neuromodulators to re-wire that circuit.

That would mean that to learn faster, you want to expose yourself to situations where you are often wrong: be often surprised and go down the wrong paths. Have a feedback mechanism which will tell you when you're wrong. This is maybe also why the best teachers are the ones who often ask the class questions for which there are counter-intuitive answers.

We already have isomorphic web apps, some day we might see a bundler advertised as "Calabi-Yau with benefits of mirror symmetry and vanishing first Chern class".

[dead] 2 years ago

I have skimmed the article and the old thread, but I still have questions:

- What's the point of sending ICMP pings to measure RTT, if they will just bounce off of the CGNAT node?

- If two Starlink dishes are talking, is there a scenario where the traffic doesn't have to "land" to go through a ground station? This could be amazing for a remote terminal back home or into a datacenter.

- Are there plans for a smaller, more portable dish?

This is crazy. Brings back a vivid memory from y2k when I was ten, how I was very sad after looking at a $5000 laptop behind a shop window. I had a reference for $5000 in my head, because we have then just sold our apartment for the same amount, before leaving the country for the West. I was absolutely certain that neither I nor my parents would ever be able to afford it.

Peter Attia explores the same notion in his recent book called "Outlive: The Science and Art of Longevity". I haven't finished the book yet, but the key point so far is that our modern medicine, as he calls it "Medicine v2", is in need of an upgrade to v3. Most people expect to become frail or senile in their late years, but it doesn't need to be that way.

This new type medicine will focus on preventing injuries like that of Jim Nielsen's knee, as well as illnesses. For example, blood sugar levels considered normal have increased over the years as the general population got fatter. If your levels are measured 125 mg/dL, maybe you'll get a suggestion to change your diet. But if they're 126 mg/dL, suddenly this is viewed as serious and you're prescribed medications.

Attia argues that there's too much focus on putting out fires like treating a stroke, but not nearly enough prevention and almost no individual long-term course correction for patients. He also argues that we have all the tools to collect the data and to make it possible. The book also delves into the science of "the 4 horsemen of death" as he calls them: atherosclerotic disease, cancer, neurodegenerative disease and the type 2 diabetes with the related metabolic dysfunction.

Can someone recommend a modern Linux DM/WM and maybe a set of applications which would be as responsive?

I have been running a bare XMonad for a couple of years with `xset r rate 300 40`, and it's okay but far from perfect. The WM seems to process its mouse events with a delay sometimes, and often focuses the wrong window whenever the mouse pointer moves.

My only experience with Gandi was awful. Bought a bunch of domains from them after they were praised here on HN, was assured that WHOIS privacy is enabled by default and without any extra fees.

Looked up the WHOIS records a minute later, and my phone number, name and email were all there. Those were .com, .org and .net domains.

by using ECC memory ECC protects from bit flips, but aren't high-energy particles required for flipping a bit? AFAIK nothing in the solar wind interaction with our atmosphere can produce them. They'd likely arrive earlier than the wind, but I also haven't heard of gamma ray bursts to accompany solar flares...

I've always been hearing that solar flares and the resulting geomagnetic storms pose danger to hard drives and electronics. Is there any truth to it?

Recently I've been building a server room, and naturally a question of EM insulation came up. If I were to protect my servers from this, I needed to wrap the room in a grounded mesh with holes of λ in diameter. What wavelengths am I protecting against? I couldn't find an answer online, perhaps because there isn't a mechanism which could flip bits or otherwise cause potential difference across my electronics, after a coronal ejecta reaches Earth. I can imagine how charged solar wind can interact with our atmosphere and cause voltage on long stretches of cable like telegraph or electricity lines, and consumers have surge protectors for this in multiple parts of the grid.

Is there something that I've missed?

Yes it's pricey, though you can get one almost new from eBay at 1/3 of the retail cost.

And yeah the batteries are great, `powertop` reported 55h battery life remaining at 60% backlight with a single `st` terminal window open. And the backlight is blindingly bright at the max setting, so it's also usable in direct sunlight.

The laptop will also charge off of any USB-C power source like the weakest phone charger, makes me think that it'll take charge even from serially wired potatoes.

I've gotten myself a Dell Latitude 7330 Rugged Extreme laptop recently. It's what my ideal laptop is supposed to be: easily serviceable, plenty of ports, indestructible and linux-friendly. Even the onboard WLAN supports monitoring mode. Running NixOS+xmonad on it, encountered no problems whatsoever after it was configured. One major difference from an ordinary laptop experience is the old-style resistive trackpad, but I can live with it because I don't use mouse as much.

The firmware can't be replaced with Coreboot unfortunately, but it is fantastic for a laptop. I have never seen a BIOS with so many configurable settings. There's even a key combo which shuts off all radio, lights and LEDs, which of course can be configured in detail.

Don't get the rubberized keyboard because it's impossible to type a sentence on. I also suggest ordering the m.2 NVMe separately to save serious money, and the Snapdragon X55 DW5930e modem from Aliexpress at a fraction of the price.

I've also heard legends about how great Dell's Worldwide repair program is where people have had parts delivered to them next day on the island of Borneo in Indonesia, but that's yet to be tested.

I have a perspective from the other end of this, as a seller. Been using Stripe for 5 years selling digital content with a low, $5 average bill. A year ago the site was likely noticed by hackers who started punching in dozens of stolen credit cards. I kept refunding manually at first, but then I had activated Stripe Radar. It made absolutely zero difference out of the box. "-Is it a 100th charge coming from the same IP in Ukraine with a Canadian VISA? No problem, charge approved, here's your success webhook.". "-Same fake TLD for the email address, for a customer number 2235? Nothing suspicious here, charge approved.".

What helped fight this was to create a rule in Radar to reject all cards without 3D Secure capability, but it had cut off a sizable chunk of legit revenue.

Custom length power/data cables like SATA/SAS with various connectors. The biggest obstacle would be that you'd need to test them, but you could start doing so with second-hand hardware. Pair it with a nice website with instant pricing calculator, and I bet you will see business.

Why can't FB simply include a clause like "No kind of automated scraping is allowed, except for search engines in robots.txt"? This would save them so much time in court, arguing over the use of fake accounts which should really be irrelevant.
