Do icons of cigarettes make you sick and destroy millions of lives? Does removing an icon of cigarette make you less sick and help save millions of lives?

That comment is actually a good politically-neutral illustration of a major force underpinning today's political hyper-polarization: people simply can't handle the mere existence of something they don't like and will respond by shunning entire bodies of work or attacking people unnecessarily.

This is definitely new as in the last 10-15 years. In the past more people seemed able to just disregard or shrug at things they didn't approve of.

We've had eras of profound intolerance before. I think this one might be unique in that it seems universal across the entire political and social spectrum.

Reminds me of [0]. The original poster's account is deleted, but it was "@Christian-Schiffer" — yes, the person who complained about presence of a Christmas-related icon in VS Code had name "Christian". And the VS Code team responded immediately, the icon was removed what, one or two days after the complaint, in an urgently published patch.

Have you heard of the Vatican’s Index Librorum Prohibitorum? This isn’t exactly a new phenomenon.

Having been raised out of a dictorship I don't have any patience for the cancelation culture that is now so trendy.

If those people would get visits from PIDE/DGS, or similar agencies, they would see how real cancelation actually works in practice.

I agree.

I think that people who haven't been raised in such a society don't realize how chilling it is to be afraid to say something wrong and constantly be aware that you could be punished for your words. It makes you unable to even think clearly, lest a slip-of-tongue gets you sent to jail. It's no way to live.

are there any risc v sbcs out there that are actually available? every one i look for is out of stock. i’d love to play around with a real chip

Starfive Visionfive 2 looks to be in stock on Ameridroid and Kickstarter? Pine's Ox64 says it will restock "in March". Last I checked, Clockwork Pi was also selling their RISCV modules separately for ~$20. If you're willing to play with RV32, there are quite a few MCU boards available - CH32V003, BL602, ESP32, etc. Many ARM SBCs also have a RISCV MCU built in, but I haven't seen any docs or reports of anyone actually using the "mailbox" mechanism to run code on it. If nothing else works, get a cheap FPGA and run a softcore?

Instruction interpreter is nicely human-readable: https://github.com/LekKit/RVVM/blob/staging/src/cpu/riscv_i....

The RISC-V isa is specifically designed to be nice and regular and easy to decode, and work with, which definitely shows here (also in the RTL code if you look at some of the well designed RISC-V cores) Of course, bot x86 and Arm started like that as well - but after 20+ years of evolution, they have to drag along a lot of history. (and one never really takes things away from an ISA, you only add new features, and at…

The ARM64 ISA does not have 20+ years of evolution as it was announced in 2011. It’s essentially a brand new ISA and has cast off almost all of the legacy of previous Arm ISAs.
