> Also it seems that it requires locking? That's not very good given that locks often need syscalls. AFAIU in most STMs all the fast paths are implemented using lock-free algorithms with just barriers.

Thanks for the detailed writeup, that must have been a lot of work. I think you guys should check out Verona ( https://www.microsoft.com/en-us/research/project/project-ver... ).

Whoosh. No, chemotherapy is not the same as holding your breath, and no, most cancer drugs don't have anything to do with oxygen, except the (unwanted) side effect that they can lower red blood cell count, causing anemia and low oxygen

Right. Like one thing that cancer needs is oxygen. So if we stop breathing (instead of laboriously stopping smoking--that's hard), then we can slow down cancer.

This is why science communicators need to master the art of to-scale visualizations, animated diagrams, and put working code into slides and presentations. Shit shovellevers are marked by a smokescreen of words and hand waving and pictures

Moral hazard here. The rest of us, and all of society, now rests on a huge pile of code written by incorrigible misers who imagined themselves able to write perfect, bug-free code that would go infinitely fast because bad things never happe

10 bit bytes would be awesome! Think of 20 bit microcontrollers and 40 bit workstations. 40 bits makes 5 byte words, that'd be rad. Also, CPUs could support "legacy" 32 bit integers and use a full 8 bits for tags, which are u

I'm surprised they didn't just add a fast path of 1 and 2 byte LEBs to the hard-won assembly they generated. These fast paths are absolutely worth it. E.g. Wizard's Wasm interpreter uses a 3 instruction fastpath to decode 1-b

I have three levels: 1. An issue tracker, even if it's just a text file for some projects. These are things that need to get done over the long term. 2. TODOs. These are actually bugs or incomplete things. The code is not actually done

Money has no inherent value; it is just a currency, an indirection, a promise. The economy must always bottom out at a physical good or service. You can keep trading promises of goods and services in various forms, but ultimately you end up

For Virgil I went through three different compile-time interpreters. The first walked a tree-like IR that predated SSA. Then, after SSA, I designed a linked-list-like representation specifically for interpretation speed. After dozens of lit
