Thanks for answering the one thing I wanted to know about this. It wasn't at all obvious to me how this might be possible using DNS only. I guess it will work for some sites, but it would be interesting to know what fraction.

Honestly, I think what TFA calls "Kagi’s implementation of Privacy Pass" is the integration of the feature into their server and clients, not the RFC (which they acknowledge), or the protocol implementation.

Exactly this. As a British English speaker that works a lot with the US it was an early learning. In British English a "scheme" has no negative connotations. It's commonly used in all kinds of legitimate places - for example

Not the OP, but I am opposed to the forced use of 2FA by GitHub for three reasons: 1) They are my repos. I should get to decide the appropriate level of security. 2) 2FA is often used as a pretext for identity harvesting which are then abus

The 3A fuse is due to the way the UK wiring system works rather than what is optimal for this device. All appliances in the UK have a fuse where they connect to the building wiring, normally in the plug, but can be in a fixed fuse-holder li

Yes, the REM is the lookup table used in line 70. Because BBC Basic had a built-in assembler it was pretty uncommon for BBC programs to inline machine code as raw data (unlike some other computers from BITD).

I posted that rather quickly, so a bit more information for those who are interested (inspired by some of the comments on the thread). I found Paul's sim by chance and really liked it because it was the first electronics sim that I had

Yes, Paul did the original as a Java Applet. I did the port to run in the x-compile to allow it to run in the browser. After that we cooperated on it for a while. I stepped back a few years ago to focus on other things, but he's kept u

I've contributed quite a lot to Paul's simulator, including doing the port so it runs natively in the browser. The photoresistor is just controlled by the slider in the side-bar. It doesn't respond to lights in the circuit. T

I did the port of Paul's sim so that it runs natively in the browser instead of needing a Java plug-in (remember them) and made various other contributions. I haven't contributed for a couple of years, but Paul still actively main

Thanks for the tip which I will try. I agree with the OP and parent, IG used to be an enjoyable experience if you were careful about who you follow, but it seems that it's now in the process of being destroyed by bad ideas borrowed fro

It is more subtle that that. Patent holders who contributed to the 3G/4G/5G standards agree to make their standards essential patents available under FRAND terms. However, this does not apply to patent holders who have not contrib

I don't have the reference, but I am pretty sure that in order to meet requirements for type-approval (e.g. FCC approval in the US) phones have to show they are resistant to IMEI modification.

It's not unknown for people to hand-draw PCBs with permanent markers in much the way you describe. It's not a new idea, but with 3D printers being common these days, it's nice to remind people of this approach to PCB manufact
