What name registrars allow one to to create unlimited subdomains on the fly like how Localtunnel does it?

thewataccount · 2 years ago

It's not the name registrar it's the dns server.

You just use a wildcard dns record, and then the webserver uses the host header to determine which subdomain was used (for webservers at least).

it wouldn't just disrupt planes, it would crash planes if this were not even planned as a contingency. as a senior operations manager for a global logistics company, I was actually not even aware of this being a possibility until TIL here

thewataccount · 2 years ago

To my knowledge planes don't use the gps for very much, and AFAIK they use the barometric altimeter for maintaining their flight level. A controllable, plane that can maintain altitude is difficult to crash. The GPS stuff is mostly supplemental and is relatively new.

And pilots can land with a visual approach and still have ILS.

You would still have ADSB with your altitude, and I beleive heading and airspeed.

Because of the existing requirement to be spotting traffic and being over 1000ft away from other planes, they should be fine.

ATC should still have radar vectoring for their airspace.

I assume planes use more then just GPS, and use galileo and the other networks like consumer GPS do.

Interesting, my insurance covered it last year. However it was related to eye trauma rather than a regular vision visit, so perhaps that's why.

thewataccount · 2 years ago

My understanding is that would be covered under medical insurance?

IIRC it wasn't that impressive in the end as instead of recognizing the places the AI apparently learnt to recognize subtle differences in street view cameras used in different locations? I might be wrong / thinking of the wrong model l and I'm on mobile without my browsing history so hard to check, but I think it was putting a lot of weight on some pixels that are noisy

thewataccount · 2 years ago

From my understanding many of the best players immediately look down to tell what "generation streetview car" they're using, and seem to know what continents/times they're from.

I still don’t understand why anyone who isn’t in the walled garden business would consent to passkeys.

thewataccount · 2 years ago

From my understanding they're basically an extension of FIDO?

You can just use a yubikey unless I'm mistaken?

It's some kind of abstract machine, like a turing machine or the machine that parses regexes, isn't it?

thewataccount · 2 years ago

This is simplified a bit - It's just a "machine" that maps [set of inputs] -> [set of probabilities of the next output]

First you define a list of tokens - lets say 24 letters because that's easier.

They are a machine that takes an input sequence of tokens, does a deterministic series of matrix operations, and outputs what is a list of the probability of every token.

"learning" is just the process of setting some of the numbers inside of a matrix(s) used for some of the operations.

Notice that there's only a single "if" statement in their final code, and it's for evaluating the result's accuracy. All of the "logic" is from the result of these matrix operations.

Imo both of these things are true:

1. For anyone who uses X for more than a few hours per month, a low fee is totally worthwhile.

2. This is a huge gamble that has the potential to wreck the company.

I've always wondered what percentage of "users" are "lurks" who never login, occasionally check a profile or click on a tweet on another website.

One of the previous uses of twitter was "announcements". Government, corporate, emergency, community, software, etc.

The previous move to require logging in was already a massive blow to that, requiring a payment would decimate it was a use-case.

I don't see company's/governments putting announcements on a paid platform. You can't expect people to pay for twitter for announcements.

I think you're right — I thought about it a little more after I replied.

I guess it'll just have to be comparisons of the general concepts. It'll be good to see the change in understanding of the prompt and the change in image detail.

If anyone at OpenAI wants to give me early access to give me a head-start… smiles

thewataccount · 2 years ago

Yeah I'll be interested to see how much you have to change the prompts to get similar styles

thewataccount commented on DALL·E 3 openai.com/dall-e-3... · Posted by u/davidbarker

davidbarker · 2 years ago

Absolutely. I've already started thinking about how I could incorporate some kind of comparison feature.

Because there's no way to control the seed, a direct comparison (using a before/after slider, for example) probably wouldn't make sense. But I could put the group of 4 images from each version above/below each other as a general comparison, perhaps?

thewataccount · 2 years ago

> Because there's no way to control the seed, a direct comparison (using a before/after slider, for example) probably wouldn't make sense.

Even if it was the same seed, from my understanding Dalle3 would have to be just a further trained version of the same checkpoint to even resemble Dalle2's image. Like stable diffusion 1.4 vs 1.5 and 2.0 and 2.1 will make identifiably similar images, but 1.5 vs 2.1 vs SDXL won't look remotely similar.

Even more so because I'd wager they changed their encoder and/or decoder too.

* I think that if they generated something like a controlnet for guidance the same way in both models then they might be comparable but from my understanding Dalle2 doesn't work that way at all.

Comparisons would still be interesting though!

Looking over the list, so much of it seems like application-level changes to stuff like messages, calls, contacts, etc. For a user who has opted out of most of that in favour of GMail, Whatsapp, Signal, and so on, it's hard to see the big draw.

thewataccount · 2 years ago

I'm not sure what you mean - the last security update fixed massive 0-day which was an arbitrary code execution caused by the image decoder. CVE-2023-41064

AFAIK every app that uses the ImageI/O api is effected by it, which includes every app you mentioned. You often don't need to even open the message for the image to be decoded.

From my understanding most vulnerabilities are from either the image decoder, text decoder, or webkit which again, effects nearly all apps. All apps can only use the webkit view, which affects nearly all of them to some degree.

I think you might be confusing the attack vector - messages is the easiest to attack since you just sent a regular text. Even if you don't normally use messages, it'll parse the image and you'll be hit by the 0 day. In theory this will work with most messaging apps.
