Yeah, the other thing that I should have noticed was the completely unreasonable cost of 1 TWh of energy. If 1 kWh cost about $0.15 at the time they trained the model, 1TWh would have been like $150M. Probably twice that after accounting fo

Thanks for explaining the calculation! There is a huge error though, which is that I mis-read the units in the second link I posted. The actual power estimate for GPT-3 is more like 1 GWh (not 1TWh), so about 6000 years and not 6 million...

I can't edit my post any more, but I'm a moron: the article says about a GWh, not a TWh. So the calculation is out by a factor of 1000.

One thing that the essay doesn't consider is the importance of efficiency in computation. Efficiency is important because in practice it is often the factor which most limits the scalability of a computational system. The human brain

The article claims about 3 million truck tractors on US roads, and puts the cost of each driver at about $65k/year. Am I correct in naively calculating something like $200B/year on the table for full-self-driving truck technology?

Again, this is kind of making my point. IPv4 had an excuse for being a bit crap, because it was designed in the early 1980s. IPv6 should have been much better than it is. Adoption was always going to be slow, but it never needed to be thi

by gnfargbl 4y ago
I think you're being unfair to the audience. The main complaints here aren't about the consequences of those legacy problems, they're about the fact that IPv6 is just such a mediocre designed-by-committee protocol. Your point

Huh, so I can effectively use a NAT64 gateway as an unauthenticated open proxy? Let's try it. First look up the IPv4 for a site that reads back your IP address: $ dig +short a icanhazip.com 104.18.115.97 104.18.114.97

No worries: it took me far too long to work the process out on my own, so I'm pleased to write it down in one place for others. If you're looking for a more cost effective solution and are willing to accept a little bit of depende

To be able to port around an IP address, you need to be able to change the Autonomous System (AS) which advertises it. The minimum IPv4 range which can be advertised is a /24 (256 IPs), so you will need one of those for full portabilit

Yep, I know. I monitor these as they appear in Certificate Transparency logs and DNS PTR records. Freenom TLDs are just junk. Save yourself the hassle and default block :-).

OK, but why don't you block Freenom domains entirely? Apart from perhaps a couple of sites like gob.gq, there's essentially nothing of any value on those TLDs. Allow-list the handful of good sites, if you must, and default block t

It looks like you're using base64 encoding. If WhatsApp allows an extended alphabet then you might be able to switch to base85 for a slight performance bump.

Ah, this confuses everyone: strings in Golang are really just read-only byte slices. They can contain Unicode, but they don't have to, and the == operator just does a byte comparison.
