RISC-V codifies this trap-n-emulate. The problem is that they are 100x to x500 times slower. Even for rare instructions this is a big hit.

And by rare I mean for applications, but the kernel itself might do them much more frequently, for example the scheduler has a interesting mix of instructions.

No longer at the Goog. 18 years went fast. I mean, most of them. Fun was had an even some actual useful stuff was made.

Now I don't know what to do with myself. Any good games in the last 10 years, I should be aware of?

I managed to move to a newer win10 via an offline installer of sorts. When finally installing VS I opted out from copilot.

I think you can rerun the installer and remove it?

I was there a few weeks ago. Its an amazing place and I am coping by knowing that everyday in USA is more "exciting" than the previous one.
Like for example you can't get covid vaccines anymore. What could be more interesting that?

So landlocked!

I can't believe they did this again.

A version of this problem is what prevents you from upgrading from WinXP SP2 to anything newer.

Then a help page told me to upgrade via the windows store which failed to launch with a classic 0x800xxx error.

Which supposedly is fixed by enabling TLS1.3, which my Win10 did not have as an option. I believe windows update just swallows the error, while at least the store crashes.

In fact, the problem turned out to be that my Win10 was too old!

Not that at any point I was told so.

First I tried to install the newer dotNets: nope! installer said "not for your windows version"
So I tried to upgrade to a newer w10, but it windows update kept saying "up to date".

Or do you find MSI too hard to use ?

Dust off a DELL laptop I had (unused), do the Win10 install dance + updates. Then I download Visual Studio installer, which errors out because I don't have dotNet 4 (??). Now the error dialog box does not even have clickable link!

C'on Microsoft. Can't you chain installers? MSI can.

Finally got some time to close the X account and try the blue butterfly. I do miss the old twitter, lets hope this comes close to it.
