clord··on Pointer Tagging for x86 Systems
The compiler can convert small known-size known-offset array accesses into registers or direct static stores and loads, but array indexing is usually on large chunks through a dynamic index via a ref or pointer, which will be via pointer math.
clord··on Google Maps Hacks (2020)
I expect a road is considered blocked up if its throughput has changed lower relative to normal. Normal bus traffic and normal car traffic don't trigger the alert, but if a wagon of phones rolls through very slow, that will sway the algo.
clord··on YouTube suspends The Hill for playing clip of Trump denying election results
Yep. I can pick a different restaurant. But I can still leave bad reviews.
clord··on YouTube suspends The Hill for playing clip of Trump denying election results
No the point is whether YouTube is better if it allows us to evaluate. I want YouTube to show me darker news and also keep my kid entertained without worry. I don’t want to be treated like the child here though. If I click on a Ukraine war video or I want to find a quote from trump to pick apart there should not be filters preventing it.

The product is better if I am in control. YouTube ought to stay out of it. It does not know my intent. If it guesses wrong it should be criticized, just like a restaurant guessing at my food preferences and allergies.

clord··on Radiation spikes in Chernobyl
It is “high ground” in the sense that it can not be safely assailed.
clord··on About the security content of macOS Monterey 12.2
Some shops call x86-64 “amd64” because AMD originated it. Not sure if Apple is one.
clord··on What is actually a heretical view?
Well, perhaps the question is: better for who? I can't watch most mainstream TV shows with my little kids. Witcher, GoT, etc. Perhaps mainstream TV of the 70s was forced to be better for a broader audience.

The shows are better for me, more entertaining, more exciting, etc, but not better for everyone in the house. The sharding of entertainment into different age groups leads to people not sitting together and watching a show together, and instead we're all in different rooms with headphones. imo that's worse.

clord··on Multiple Sclerosis Causality
I wonder if MS is like the EBV version of shingles: if you don't get it early, when you do, it's a much worse disease. Most people pick it up early, but those who manage to avoid it and then get it late are in danger. Another instance of hygiene hypothesis.

Could this victory be related to the potential metaverse rename of Facebook that was in the news the other day?
clord··on Hunter S. Thompson Interview on Gonzo Journalism (1975) [video]
> consensus around basic matters

But the thing is Joe (and others) will have the conversations you’re describing- it’s not forgotten. Part of having a good conversation is being comfortable with being wrong. He’s explicit about being a joke comedian sports commentator, and can sympathetically talk with anyone. Conversations with ground rules of truth are those that tend to be dry and pre-processed. The listener can think too and figure out what makes sense. Part of what makes gonzo fun, too.

clord··on Common cold combats Covid-19
right, the first link was talking about t-cell immunity, I was wrong to say 'antibodies'.
clord··on Common cold combats Covid-19
> I'm not disparaging, I'm asking if it actually grants any. Does the body actually learn to fight COVID if it's just throw up defenses for the Cold?

Depends on the cold, I think. This rhinovirus might just be priming the immune system. There are coronavirus colds that might provide antibodies[0]

> Pox parties only worked because the parents and grandparents were already immune. Instead you're creating your own little super-spreader event that will move through whoever they come in contact with

I'm not suggesting we do it willy nilly. This summer could have been a great opportunity to organize camps with immune adults overseeing such events.

412 people under 18 in the US died from COVID, whereas non-covid pnumonia is 924 (both in spite of measures to control respiratory viruses). It's pretty clear that the benefit of such parties on older people would outweigh the cost to the kids, especially when you factor in the exploding teen suicide rate attributable in part to the lockdowns affecting social lives.[1]

clord··on Common cold combats Covid-19
I’m surprised to see people disparaging natural immunity. This news about the rhinovirus is great. We should not turn our backs on any method of reaching herd immunity. There was previous news that one of the coronavirus cold strains also provided good immune response to sars-cov2. And of course cov2 itself has proven to produce a very effective antibody response such that those for whom it is less dangerous than flu might consider trying to get infected (don’t take my words as medical advice; talk to your doctor!). I’d consider bringing my young kids to a ‘pox party’ to help get things under control, given the latest evidence. The only reason I don’t still is social pressure, but the science is getting pretty clear that this virus is more like chicken pox than we thought, including it’s age dependent effect curve.

Especially now that we’re seeing that the effect of current vaccines is waining over 6-12 months, it’s time to start thinking more widely as the first people with the vaccine are coming back into risk. Animal reservoir data suggests this choice might be forced anyway - we can’t go vaccinating all the bats.

clord··on Using WebAssembly threads from C, C++ and Rust
substitute "posix threads" to see why it was written this way.

WebAssembly is the platform (aside: and an assembly langauge) that provides WebAssembly threads. It makes sense to say "use posix threads from C or C++". Posix is underneath whatever language you use.

Saying "running posix threads written in C or C++" seems to suggest that someone is running their own custom threading library in C or C++.

clord··on Google Drive bans distribution of “misleading content”
My mind boggles that people have opinions like this. It is so anti-liberal. Every evil regime in history takes it upon itself to define and eliminate hateful content, using the contemporary unconscionable act to justify this evil.

To be a good liberal, Google has to decide if it's a publisher or platform. IF it's a publisher, then the hateful content is coming from them and they must take editorial control of google docs and whatnot. If they're a platform provider, then they get the same protections as telephone network operators and others from the actions of their users.

This current situation is the start of the road to tyranny.

clord··on Video tutorials now on PeerTube
What are the per-viewer costs these days to host video files on a plain web server? Perhaps with a CDN?
clord··on John Carmack on JPEG
some images manage to communicate in spite of high compression. X-rays are an example of an image where the cost of misinterpretation is very high.
clord··on Testing a few new designs that don't show the public dislike count
noisy signal is better than no signal, which in turn is better than manipulated signal. at least with this change they won't be deleting[0] dislikes anymore.

clord··on Hubble Telescope Captures a Rare Asteroid Worth 70k Times the Global Economy
We already do. Several grades of stainless steel use a lot of nickel, and these are used in many applications. Also it is quite expensive which prevents it from being used generally.
clord··on In Praise of the Unambiguous Click Menu
I didn’t test this but won’t the focus-within trick work for click menus too? The user clicks the button (which must be a child of the container) so focus moves within the container and hence the submenu can show.

nav:focus-within > .submenu {display:block}

(Edit: oh it’s mentioned in the article briefly without much explication of the need for js)

The ship is over the horizon but a fiber optic effect caused by inverted thermals projects the ship into the sky for the distant observer.
clord··on 'Wild West' mentality lingers in modern populations of US mountain regions
I have a 30m tower, and at the town I have a friend with a good connection. I rent roof space and pay half the bill. ISP is ok since it's a business plan, and both of us are using it for mainly business — it's similar to a shared office that provides internet from their perspective.
clord··on 'Wild West' mentality lingers in modern populations of US mountain regions
I live in a similar way in Canada, and I run long range ubiquiti radios (~12km) to nearest small town. get 150-200mbps and since I have battery backup + generator, usually the only reason it goes down is if the ISP router dies. I get ~1 bar of LTE that flickers to 3g, but with wifi calling it's not an issue. In addition to changing my own alternator, I run a small ISP for my neighbours :)
clord··on Is It Time to Kill the Penny?
The problem with checks and balances is that partisanship is paralyzing. If each side deems their causes good and the opponent evil that must be stopped, nothing happens. Some mechanism is required to build cooperation. Patriotism used to serve that role in the US but it’s not functioning since it too is becoming political.

The @include thing makes me wonder if a circle library could compete with modules.

This works during template instantiation. So your macros can respond to types and values from such parameters. Also it seems to know about scopes.

Would be cool to have a podium that a user can step up to and speak to all with no falloff. Perhaps with some sort of permission or nomination.
