I don't disagree, but the article does. RH describes an architecture where setup functions create callbacks, independent of the receiving type. If I were to steelman him, it would be something like this: "in a pedantic MVC system,

Red flags for me when I see nonstandard functors in a c++ codebase (esp if the "glue" is in a setup function independent of the objects): (i) Have they thought about the relative lifetimes of the sender and receiver? (ii) Is the c

Distinguishing that in-hindsight Lucent was committing accounting fraud and present firms aren't is a load-bearing assumption here; for all we know the big players in the AI bubble just haven't been outed yet.

Well, there's several implementations because it's a bit of a leaky abstraction, and implementation details matter/vary across use-cases, which is consistent w/ my experience of rust having heavy fragmentation in applyin

Anticipating pushback: yes, you can disallow "pointer arithmetic" on handles, and store fingerprints in the "slots" to ensure they still contain the handle's identity to detect user-after-free, but congrats, you&#x2

"It's the term used by the infographic for, at the minimum, projects without a publisher." Term used by _whom_? Because nobody at DICE or GDC talks like that -- just peanut gallery blogs. "And it turns out that it's

"hobby project" as a label is a patronizing deflection.

Account for labor + marketing (or if you have a publisher, clawbacks on advances), and those are failure numbers.

Speaking as an independent gamedev: review-based storefronts (e.g. steam, egs, etc) select for the 1% of hits, but offers no pathway for the midrange -- everyone else gets lumped in with the slop.

Lotsa detail, but not to the point: does cmov depend on branch prediction or not?

The article's claim is that branchless code avoids branch-prediction, and therefore optimizes better on speculative CPUs for certain workloads. Jump instructions obviously incur branch-prediction; my question is is CMOV incurs branch p

You're misreading between the lines. I'm objectively on the left. As I understand things, there is no "line" and no "middle", except for media-types dispatched to hype the status-quo.

Is cmov branchless, or just branching by another name?

If you think Chicago School economics is centrist, then "centrist" is just another word for conservative.

No, just sounds like you know some dense conservatives.
