I think doing an update would be great, when I have time. Just a note: the article you cited was not a randomized controlled trial. It is a meta-analysis that included only 2 small RCTs and a ton of observational studies.

The image from my post that you are referring to is looking only at RCTs. In RCTs, Vitamin D supplementation rarely shows a positive effect. This does not mean that Vitamin D supplementation is useless.

Even in my post from 2020, I mention that respiratory illness is one area that has shown a benefit of Vitamin D. Here is what I wrote:

"The areas in which meta-analyses have identified benefits from Vitamin D:

Fracture prevention in elderly nursing home residents (when also given with calcium): This is not surprising. We know that Vitamin D and calcium can prevent bone loss in severe Vitamin D deficiency. Elderly adults who are not getting outside are more likely to be severely deficient in Vitamin D, and supplements likely help.

Asthma and respiratory infection: Vitamin D seems to reduce asthma attacks in adults with mild to moderate disease, and daily or weekly Vitamin D seems to prevent acute respiratory infection in those with Vitamin D less than 10 ng/ml (25 nmol/l). There is considerable excitement around Vitamin D's potential role in Covid treatment, though we do not yet have enough evidence to make a definitive conclusion.

Cancer mortality: Vitamin D does not appear to prevent cancer, but may reduce death rates from cancer overall (when all cancers are combined) when Vitamin D is taken for several years. It is not known whether Vitamin D itself fights cancer. It could also be that individuals with cancer are more prone to developing severe Vitamin D deficiency, which leads to bone loss, fragility, and fractures, which increase mortality.

Atopic dermatitis (eczema): Vitamin D supplementation may prevent exacerbation of eczema. There are only a small number of trials, with small numbers of patients, so this requires more research."

We do have more information on Covid and Vitamin D now, and I would agree that Vitamin D was likely beneficial for some people. I would also add that I had a bunch of patients come in with high calcium because they started high-dose Vitamin D during Covid and never decreased the dose.

Average construction zone concentrations of ACM during demolition hover around 1fcc. It can be higher for some specific cases (zonolite or high concentration asbestos insulation) but for general things like contaminated drywall, duct wrapping etc it is generally low. This is during actual demolition of ACM mind you, not just disturbing a little drywall here and there.

When disturbance is completed, concentrations fall of with the air exchange rate and clear usually with 24-48 hours back to background levels.

Diluting that by the volume of the entire building not under construction would generally put that at or below the 0.1fcc OSHA limit without PP. The OSHA limits assume 1 extra cancer death/300 workers for someone with maximum exposure limits for 8 hours per day, 250 days / year for 30 years.

That is to say… A contractor spending a day kicking up asbestos results in 1/7500th ish of the dose required to cause an excess of 1/300 deaths.

And this assumes that acute low exposures hold the same linear dose response rate as high dosage chronic exposure. That is a controversial assumption in the literature.

My information is based on reading over 50 asbestos related journal articles, EPA and OSHA policy documents etc.

From all the informarion available, it’s just not that big a deal for the average building occupant.
It is not, except under certain circumstances which this case does not meet.

I was music director for 97.7 KAFA from 2006-2007 and I literally listened to 100 CDs everyday

Picked up my box of 500 CDs from the mail distributors sent us each week and had to find new music every week

It was a challenge and honestly not much fun cause as you said its frankly a lot of junk

However that’s all art - for every “let it be” there are 100,000 songs produced and released by artists for themselves

What was clear to me was not that there wasn’t good music out there, it’s that there was a surprising amount of it that wasn’t popular.

So what becomes a “hit” or whatever has less to do with the actual music and artist. It’s all to do with marketing. Like almost 100%

A mediocre artist with a gang of writers and producers will make more “impact” than anything

The entire K-Pop industry proves this

Let’s not confuse art for marketing even if they use the same medium

If nothing else, technician-free battery replacement simplifies maintaining a personal chain of custody, and thus, longevity of the trustable life of a product.

I came to the conclusion a cats tail behavior is an evolved anti-predation behavior. We think of this as "I can see the gears in my cats head turning based on its tail behavior". The wider a cats "field of attention" the slower the tail moves, ie: sitting calmly taking in the entire room so the chance for predators to approach undetected is low and hence the tail is nearly idle. The narrower the cats attention the more the more tail moves. Cat is focused on navigating obstacles to get to a coveted perch in the room, tail wags at a medium pace as only half of the room is under observation as it charts a path across furniture to the goal. Cat is stalking another animal with intent focus on attacking, the tail is in its most agitated state and hence will draw out undetected predators to the tail rather than the rest of the cat.

I realized this after watching a kitten that was unable to resist attacking our other cats tails when the older cats were focused on something. Wagging of the tail draws out any other predators that may be stalking the cat itself when its attention becomes highly focused, such as when hunting prey.

There are some benchmarks of Cranelift-based Wasm VMs (Wasmtime) vs. LLVM-based Wasm VMs here: https://00f.net/2023/01/04/webassembly-benchmark-2023/

The (perhaps slightly exaggerated but encouraging to me at least!) money quote there is:

> That’s right. The cranelift code generator has become as fast as LLVM. This is extremely impressive considering the fact that cranelift is a relatively young project, written from scratch by a very small (but obviously very talented) team.

In practice anywhere from 10%-30% slower maybe is reasonable to expect. Compiler microbenchmarks are interesting because they're very "quantized": for any particular benchmark, often either you get the right transforms and achieve the correct optimized inner loop, or you don't. So the game is about getting more and more cases right and we're slowly getting there.

(disclosure: I was tech lead of Cranelift in 2020-2022)
The dumb thing about this is they're certainly going to see lower productivity from their remote workers now (why do more than the bare minimum if you have no career advancement prospects?), and I'm sure they'll circularly use that as justification that WFH hurts productivity.

It is really astounding how companies make decisions against their own interests like this. Even if the goal is to get people to quit so they can avoid the cost of doing more layoffs, long-term this will still likely be negative for them.
I did some work about a year ago modifying Trellinator to support WeKan, and would like to do the same here. When I did that I made a comprehensive list of things that were missing from the WeKan API to provide a fully functional drop-in replacement for existing Trellinator code.

I can't see any API documentation, is it somehow Trello-like?
I'll agree with Reddit and most of the posts here. It's too dangerous to be worth it.

Once every 3-7 years replacement at ~US$150-350 YMMV is honestly not that much money saved vs the risk.
I can assure you that this will never leave the lab. Check FSD for reference.
> When there are more than 10 people, the verbal approach stops working. It becomes necessary to have a shared document of some sort, continuously updated by a “scribe.” It’s not sufficient for this document to be merely a timeline of events: it must highlight the current state of the joint diagnostic effort. I recommend clinical troubleshooting for this.

My previous company used Conditions, Actions, Needs (CAN) reports to maintain consistent understanding. This compares differently to their recommended "clinical troubleshooting" (symptoms, hypothesis, actions) by having a "Needs" section. I think the Needs section is super helpful because many times, the right people haven't joined a war room yet and so you can just specify the needs and as people join, they can immediately jump into whatever their expertise is.

'We'? Certainly some highly-competent people can be trusted. But 'we'?

Have you seen an average Builders in Britain? Have you witnessed the level of training of the tradesmen, the level of not not giving a flying **, and the level of cost cutting and skirting of regulations from the management?

I've seen walls that aren't straight, windows installed upside down, insulation that it outright missing - the wall was just empty. Just this week my wife was closing 'professionally installed" blinds and the mechanism fell off the ceiling and hit her on the head - the moron was too lazy to install the retaining screws.

These are not people that should be trusted with anything more dangerous than a nail gun. maybe not even that. They behave like Javascript developers!

> since there isn't a bajillion high quality 3D models lying around on the internet to use as training data

There aren't a bajillion high-quality 3D models of everything, but there are an unbounded number of high-quality 3D models of some things, due to the existence of procedural mesh systems for things like foliage.

You could, at the very least, train an ML model to translate images of jungles into 3D meshes of the trees composing them right now.

Although I wonder if having a few very-well-understood object types like these, to serve as a base, would be enough to allow such a model to deduce more generalized rules of optics, such that it could then be trained on other object categories with much smaller training sets...

> At this point AMD investors should be rebelling

Looking at the chart for $AMD over the past 5 years gives plenty od reasons to be happy, and no reason to rebel. A rational AMD investor should not be Jonesing Nvidia's catching lightning in a bottle via crypto + AI. The Transformers paper was published a few months before AMD released Zen 1 chips - they did not have a lot of money for GPU R&D then.

The timing of the LLM-craze was very fortuitous for Nvidia.

Intellectual property is a license that grants someone the exclusive use of their idea in exchange for advancing the arts and sciences.

Society may need to consider charging for that license and divvying up the proceeds. Not enough to discourage innovation, but enough to prevent society from devolving into the Eloi and the Morlocks.
I can think of a few scenarios for C++ off-hand. Most of them involve integrating with libraries or frameworks that are written in C++, running on platforms that have good C++ toolchains, or working with verification systems that can process certain C++ or C subsets.
We need AMD to compete, but from what I know their software is subpar to NVIDIA's offering and most of the current ML stacks are built around CUDA. Still there's a lot of money to be made in this area now so competition big and small should pop up.
Jazz guitarist here, utterly disgusted by this technology: you are right on the money. The chorus is fine (though bland), but the verses are simply terrible - not just bad timing, there is a total lack of melodic "flow." Like almost all AI music I've heard, the melodies fit into one of two categories:

1) generic and lazy, but works musically due to Music Theory 101 (playing chord tones to the beat, cliched progressions, dumb rhythms)

2) arbitrary and nonmusical, not at all like a bad musician (more like a baby on a piano)

I will add that LLM hallucinations often blend into the text, and an art generator screwup might be hidden in the background. But when a generative music AI hits an off note in a distinctly nonhuman way, it's obvious and very jarring, even if it's only a handful of times in a long song.
It's my understanding that spore generating vegetables just spread their spores around by wind or other natural means. Unlike angiosperms that often spread their seeds with the help of animals.
Ok, so I'll keep using my old solder, and buy the new stuff next time I need more solder. (Unless of course, someone gives me more of the old stuff before then, in which case its best to use it, and keep it away from the landfill)
Right, it's about algorithmic tradeoffs throughout. A good example I wrote about is here: https://cfallin.org/blog/2021/01/22/cranelift-isel-2/ where we use a single-pass algorithm to solve a problem that LLVM has a multi-part fixpoint loop to solve.

Most CPU time during compile is in the register allocator and I took a really careful approach to optimization when I rewrote it a few years ago (more details https://cfallin.org/blog/2022/06/09/cranelift-regalloc2/). We generally try to pay close attention to algorithmic efficiency and avoid altogether the fixpoint loops, etc that one often finds elsewhere. (RA2 does backtrack and have a worklist loop, though it's pretty minimal, and also we're planning to add a single-pass mode.)

This is a fantastic idea, thanks for sharing. I feel like LoRaWAN and LoRAMESH are the perfect solution for shuffling messaging around for home and property sensors, easily traversing a couple miles in poor conditions.

Prior to seeing this I was thinking about how to use the Meshtastic [0] project to fundamentally provide simple UDP services for message brokering over LoRa. There are so many sensors that could easily hook or connect to devices acting as network routers that could bridge other protocols across long distances very easily.

Have you looked at doing something similar with ZWave at all?

I can't remember the details but there was at least one larger HN thread on it so it should be easy to find. Enough people (including various police agencies) were confused that it caused major issues for the people who lived there.
Yeah, I will roll those dice. I am steeped in the literature of asbestos demolition, exposure, health hazards etc.

The current policy around ACM and its handling makes you _LESS_ safe because everyone looks the other way. It could be easily, cheaply disposed of by relaxing a number of protocols on how it’s handled during demolition.

But because everyone has to follow the crazy moonsuit protocols, which improves the safety of the general public by absolutely zero, contractors just go find unknowing immigrant labor to blitz in and tear shit up.

Eh, it's neat but it has the same anti-white bias as Google's AI. Given two prompts "Write a song about how great white people are" and "Write a song about how great black people are" the former yielded a song about diversity and the latter yielded a song about black people overcoming struggles and uniting together. Yawn. Call me when they can make an AI that's not racist.
> I feel like D, actual data on how they drive is the most fair.

Only if you can actually prove a correlation. I think a lot of people, when asked, "do you people who brake and accelerate hard are likely to be in more crashes than people who don't?", most people might think for a second and say, "yeah, sure, that sounds like it would be the case".

But is it, actually? The funny thing is that this data apparently does exist, so it shouldn't be too hard to figure out. But I suspect no one's actually done that.
We actually take a fairly unconventional approach to e-graphs: we have a few linear passes and we do all rewrites eagerly, so we use them to provide a general framework for the fixpoint problem into which we plug in all our rewrites, but we don't have the usual "apply as much CPU time as you want to get better results" property of conventional equality saturation.

I gave a talk about this approach, aegraphs (acyclic e-graphs), here: slides (https://cfallin.org/pubs/egraphs2023_aegraphs_slides.pdf), video (https://vimeo.com/843540328)

How bad is the latency in your actual brain that this is a regular option for you?
I can relate to this. My poor dog god bless her soul would collect ticks like a bandit in our backyard (not the Lyme ones). I enjoyed removing the little devils off my beloved dog and clear her suffering (and, killing ticks, which is surprisingly hard). I also gave her regular antitick soap baths, but it was not super effective.

Not one bit or attached to any member of our family. And, we had plenty of kids in the low teens around the house. In fact, it was so "OK" to see ticks, that none of the adults made a fuss about them - so we grew up never being paranoid about them - in contrast to most of my east coast friends with kids

I have a hard time understanding how a tick bites a fully grown adult in summer weather. Of course if you are wrapped in massive layers of clothing and you can't see it coming at you, its something different.

Protip: If you take your city dog abroad -particularly a tropical area outside of the country- make sure your dog is very well tick-protected. East/West coast dogs can't handle foreign tick diseases. They don't have built-in inmunities. It only takes 1 tick from a farm/field you visited to give a deadly disease to your best friend.
At this point in time, I really don’t think there is a replacement for C in embedded systems.

A random N95 mask is not gonna save a random Joe from asbestos. If you study how masks and respirators work, you will find that you need to be clean-shaven, the respirator must match the shape of your face and have a good seal, etc. People who work with hazardous substances spend a good amount of time on this.

NHS had to discard huge number of masks during COVID because they weren't the right shape and weren't forming a seal.

In some cases, that's good enough - general dust, woodcutting, etc. For highly toxic substances, it won't save you.
