It is a common misconception that a DNS TXT record can only contain 255 bytes. This is not true, a TXT record can actually contain much more than 255 bytes. rfc1035 defines the <character-string> string object, which consists of a len

I'm not saying it is simple in any way, but I do think part of having a competitive edge in, AI at least at this moment, is having access to ML hardware (AKA: Nvidia silicon). Adding more parameters tends to make the model better. With

Depends a bit on the model, but you should be able to find it close to the mobile data toggle, do not disturb toggle and the physical power button.

I can't imagine that overclocking was already a thing back in the 70s. So just because Intel specified a narrow operating range doesn't mean that it is guaranteed not to work outside that envelope. I can imagine Intel to just ha

Part of this could be explained by the low/favorable price of the Yen at the moment. Toyota cars are currently rather cheap to buy in Europe and USA. But Toyota still primarily offers ICE and hybrids, they are late to the BEV game. Whe

Not just the dashboard, the API is giving authentication errors as well. Looks like they responded quickly though, and are already on it: https://www.cloudflarestatus.com/

Why wouldn't you be able to set up your own email server anymore? Yes, you need to configure authentication (DKIM, rDNS and preferably DMARC) but you should be doing that anyway, the hard requirement doesn't change that. One-click

The majority of email comes from major email providers (think Google, Microsoft, etc). They certainly own HSMs. Hence my statement that this scheme only really works for self-hosted solutions, because you won't be able to obtain the ke

There lies the problem IMO. The publication date of the DKIM record will be _after_ the email has been sent. Obviously there is no real way to 'prove' the publication date of a DNS record, other than asking the DNS service provide

From the looks of it, this is not a problem that Google can fix, this is just how email works. In order to send email on behalf of a domain (the part after the '@' in the sender email address), the domain must authorize the sender
