If you think mainstream COVID vaccine-related info is "propaganda" and "lying", then you don't "accept the vaccine". Additionally, most people agree with the mandates: https://news.gallup.com&#x

People have literally died from not being able to receive treatment from their diseases because hospitals were filled with COVID patients who didn't take the vaccine when offered.

The public is broadly on board with vaccines, including mandates [1]. The entire problem is that COVID videos are spammed by an unrepresentative group of antivaxxers. [1]: https://news.gallup.com/poll/354506/update

An enormous number of public opinion polls broadly show acceptance of the COVID vaccine, including mandates [1]. Yet every video demonstrating the efficacy of the vaccine that makes it to the front page of YouTube is spammed with dislikes (

Exactly. Public opinion polls show that the COVID vaccine is widely accepted. Yet every COVID-related video on the front page has an 80% or more dislike ratio. Antivaxxers have hijacked the dislike tool to spread their propaganda, and the c

Every video that correctly describes the benefits of the COVID vaccine and makes it to the front page is spammed with dislikes, and this constitutes a major threat to public health. No, this is actually a very important change.

The idea that deflation is better than inflation (or, more broadly, that inflation is undesirable for the consumer) is libertarian ideology that I reject.

I'm not interested in being sold libertarian ideology. I want someone to defend cryptocurrency on its nonpolitical merits. What can it do for me?

C# and Java have very fast compilers. A JIT is generally better for compilation speed than Go's approach, as a JIT only compiles code when it's executed. javac and csc.exe don't do any up-front code generation, while Go 6g&#x

The Web would definitely not be better had Tcl been the language of the Web instead of JavaScript. At least JS has working closures.

Yes. Several cities in the Bay Area have shared sidewalks; e.g. Embarcadero in San Francisco, and Foster City has a ton of them. I don't know of any cities that allow all sidewalks to be used by bikes, but I'm sure some exist.

Reference counting is a form of garbage collection. Remember that reference counting and tracing garbage collection are simply two extremes of a continuum of approaches. Must-read paper: "A Unified Theory of Garbage Collection".

I wonder if it'd make sense to have the const generic parameter be the number of bytes (or words) that the bit set needs, instead of the number of bits. It's ugly, but it could allow the optimizer to eliminate many runtime bounds

No-MMU Linux usually just disables fork and uses vfork instead. The really annoying part is that you can't use shared libraries without doubling the size of function pointers (FD-PIC ABI).

It's important to remember the biggest reason why overcommit exists on Linux and macOS: fork(). When a process forks, the vast majority of the child process's memory is safely shared with the parent process, due to copy-on-write.

I think you'll find that if you want to prove a program correct (which vanishingly few people really do in practice, but anyway) you will find it infinitely easier to do so if the language it's written in is type- and memory-safe.

The lifetimes and borrow check make sure that, no matter what order your threads execute in, nothing bad (memory-unsafe) will ever happen. But it doesn't say anything about what that order is . That's what a memory model is for.

by pcwalton 5y ago
In reality, the #1 thing that helps to verify correctness, if that if what you are after, is memory safety, something Rust has and Zig does not. In fact, in one common PL sense, a language that is not memory safe cannot be "verified co
