though it's surprising that they just livestream this shit, it's so visibly evil

one would expect they'd do that shit behind closed doors but I guess if you euphemize shit enough, you can be openly evil

wasted a whole day to get up to speed but learned a lot as well

however much you might hate these freaks, I'm almost certain (without knowing you) - you do not hate them enough

detonating these leeches into the stratosphere would make the world an objectively better place

their whole sales pitch is to get other people to transfer money into their own pockets
November 27, 2025 at 2:50 PM
going back to the first tweet, the doublespeak there was truly insane

every objectively bad thing is rephrased euphemistically

e.g. they might say "there's room for consolidation" which means "the regulators might allow a competition-reducing merger or acquisition to happen"

and what's especially disgusting is the way they're salivating over getting state-owned companies to "go public" - to become fully or partially privatized and thus leak dividends into the pockets of so-called "investors" (but I very much prefer to call them "thieves" - what they objectively are)

another thing is that whenever they talk about bonds, it's pretty clear that they have this open secret that the "high yield" (high %/risk) bonds (loans) are crap and they have no plan for the case when they can't be repaid

throwing away credit ratings for more $$$, cosmetic/volatile "collateral"..

I do wish people stopped using shitty opinion pieces as the sole excuse to do silly things 🙃

on a related note, EU privacy/AI law is being gutted currently because of a similar document (Draghi report) containing no references to any research or anything similar for many of its most frequently cited key claims

this seems like the most likely thing he would do

yet can't help but think that prediction seems like such a tiny aspect of human cognitive functioning though

one can't even represent "let's just try it and see what happens" in a predictive system at all

"fragmentation" is another word for "more competition than we'd like to have"

the only way you can "address challenges" is by removing the competition

I was talking about the process of debugging and said that GC makes connecting observed effects to the root cause structurally and systemically easier.

I have *never* argued against what the cause is or that it should be hidden, this seems to be a neverending pancakes/waffles issue.
November 15, 2025 at 7:08 PM
it seems another option would be to fully interleave the points (so that 0-1-2 are the original triangle, 3-4-5 are the first points on the original edges etc.)

the main benefit would be: location = i/3 and edge = i%3

partial interleaving like the above seems to require finding the ring first
November 15, 2025 at 4:48 PM
yeah with nearest rounding the sum can only be less than ~97.5

those numbers could only work if they rounded down, though even then the probability of this outcome seems low
November 15, 2025 at 7:33 AM
you keep acting as if I said something that I never did

of course they don't eliminate "the bug"

but they do limit the scope and the ways in which it can manifest, turning it from "basically anything can happen as a direct outcome" to "the bug will have one of these few direct outcomes"
November 15, 2025 at 5:00 AM
I don't think lifetime control is the GC's problem though (nor do I see UAFs "all over the place" but I guess that's the snarkiness)

nor do we even disagree on what/where the actual bug is

I was merely pointing out that GCs eliminate a category of issues that can massively complicate diagnostics

also, it looks like many games using the original Lua library (e.g. not luajit) have shipped with this particular UAF lol (github.com/redis/redis/...)

it appears to be also present in versions 5.0 and 5.1 of the original Lua source code

btw even some of the most widely used projects have UAFs lasting more than a decade before anyone finds out about them

www.infoq.com/news/2025/11...

so it seems more than reasonable to be concerned about UAFs specifically, and to note that operating inside managed memory environments prevents them

overwriting of freed memory only detects immediate misuse of actionable memory (e.g. dereferenced pointers), not other reads/writes or abuse of subsequent overlapping allocations

UAF is not a "red herring", it's my entire point - it often requires aggressive instrumentation/segmentation to diagnose
November 15, 2025 at 3:45 AM
I'm not missing the bug (???), you're missing the fact that to get to the bug, you need to first observe the effects of the bug (which with UAF may be completely unrelated) and then backtrack to what caused those

I'm starting to wonder... have you never debugged any nasty UAF issues?
November 15, 2025 at 2:17 AM
that's not the difference between them

while a GC may indeed hide use of stale objects, use-after-free does not guarantee a crash, or that the issue will manifest itself near the systems involved

UAF writes may also result in random buffer/pointer/heap corruption anywhere in the process
November 15, 2025 at 1:30 AM
I am only sticking to the broadly accepted definition that I used which is crucial to my original point

it doesn't matter at what level the bug is, what matters is the path from observing effects to fixing the bug

a GC ensures that the effects don't go as far from the cause as they could otherwise
November 14, 2025 at 11:42 PM
what exactly isn't true or would be environment-specific?

that a problem with a larger surface area/scope and lower predictability (guessing the cause given observed effects) would be more difficult to solve?

didn't even think that was controversial lol
November 14, 2025 at 11:26 PM
use-after-free (as defined at cwe.mitre.org/data/definit...) can be a complicated issue to resolve and GC removes the possibility of having it

accessing an object after its logical destruction doesn't even compare - any modern IDE will even enumerate the accesses, most cases are fixable in <1 hour
