Push lawnmowers, dirtbikes, or chainsaws typically do not have microchips, and they are all quite complex. Also, old elevators often had purely relay logic, and I've heard that it is often more cost-effective to repair old elevators than to replace them outright, so if you live in a really old building the elevator might still be click-clacking away.

Then there are washing machines and dryers. Most new models are stuffed to the guts with computer chips, but older styles are still available, new (Speed Queen) or used (appliance refurbishment shops). Old ones are purely electro-mechanical, with some rather ingenious timer boards that do a lot with only a few contacts, a tiny motor, and a large resistor.

(I helped repair an old dryer a few months ago: the large resistor is for the dryer's auto dry mode. The wetter the clothes, the more power the heating coils will draw through the resistor, which lowers the voltage of the power the timer motor receives, slowing it down. Once the clothes start getting dry, the voltage goes back up and the timer speeds up again.)

> Cryptocurrencies have never claimed they address the hardest parts of financial inclusion. Cryptocurrencies solve the issue of trust.

Uh, what now? They actually do a worse job than traditional finance. What happens if I pay for something with a credit card and the vendor fails to deliver? Why I dispute the transaction and get my money back. It's less important that I have absolute trust in the vendor, because I have fall back mechanisms. Cryptocurrencies are deliberately designed so that can't happen.

The only "trust" problem cryptocurrencies solved was keeping track of stuff like account balances in a distributed ledger, but that's purely a problem created by the ideological choice of a distributed ledger.
Considerations for Californians looking to move out of state (2019)
Your typical $400-$500 tank style gas water heater has none of those things. It has a PCB with some analog circuitry to do sparky magic to light the pilot light. A gas/propane heater or stovetop is basically the same thing in a different form factor.

Tankless water heaters are necessarily much more fancy.

The difference is that unlike microchips, wheat can't be stored indefinitely. Eventually it rots. And reserve storage capacity is very limited; they have to make room for the next crop. The worldwide wheat market is huge and fragmented so no one can really corner the market through hoarding. An electronics manufacturer might not be able to easily substitute a '328 for another microcontroller, but an Egyptian baker can easily substitute French or Indian wheat for Ukrainian wheat as long as the transport can be worked out at a reasonable cost.
Why only an "important" call? Once you've made the investment in the hardware, it's pretty much a simple matter of just plugging it in, as long as you're at home. I've found that the higher sound quality from a dedicated external mic more than makes up for any minor inconvenience having to deal with hardware, unless I have to be mobile for some reason.
Because the margins on gas are tiny.

The gas stations would have never had any credit card uptake without it and people have to buy gas and are extremely price sensitive so would have continued shopping at cash only gas stations.

Unlike say a clothing store where the convenience of credit overcomes the price sensitivity, you can defer the purchase and the merchant has higher margins.

100% pair programming is not compatible with deep thought and concentration.

However, solo thought doesn't necessarily activate all neural pathways that will solve problems.

Much like explaining problems to someone else often causes you to realize the bug, social interaction activates communication, idea formation, recall, association, and error checking neural pathways that don't necessarily fire when thinking in isolation.

So for 100% pair programming: again with the dogma in IT. 100% code coverage. TDD. Strict agile/process alignment.

Stop with the dogma.

"I wonder why so many HN readers are interested in phenethylamine-type chemicals."

First, MDMA is a phenethylamine, and it's one of the most popular psychedelics.

Second, if you look at the trip reports of the "magical half-dozen"[1], they sound amazing, so they're pretty interesting just for that.

Third, even if one never does any of the phnethylamines in PiHKAL (I personally haven't, except for MDMA once many decades ago) they're still fascinating in terms of their effects, the potential for research and further development, and PiHKAL the book is interesting and admirable for the wealth of information it revealed on previously unknown compounds, the story of how they came to be, and all the self-experimentation Shulgin and his friends did.

> I believe that paper predates the introduction of speculation-blocking MPKs

That isn't enough, because you can induce misspeculation through paths that do (or would) have access to appropriate MPKs and do almost anything you want, including disclosing information through sidechannels you do have access to. Loading an MPK is akin to changing address space protections; it has to be a hard barrier that cannot be speculated through. You cannot even have code mapped that would have access to those MPKs, as you can induce misspeculation into this code.

> It's an open research question but my gut says yes.

My gut says no. There is just too much dark stuff going on in hardware. Sidechannels are outside of models. You can't verify anything until you have not the model, but the whole design of the chip.

Also, variant 4 is not addressed much in the literature. I couldn't write what I wanted to write because of NDAs, but I have personally written PoCs that basically say hardware has to turn off memory speculation or you end up with a universal read gadget again. There is no software solution for variant 4.

I'm intrigued by:

> Turning on UAI would allow user space to create pointer values that look like kernel addresses, but which would actually be valid user-space pointers. Those pointers can, of course, be passed into the kernel via system calls where, in the absence of due care, they might be interpreted as kernel-space addresses. The consequences of such confusion would not be good, and the possibility of it happening is relatively high.

Userspace can already forge "pointers" with whatever it wants in their bits. If the idea is to allow the transfer taggued pointers to userspace to the kernel and from there back to userspace, maybe just don't allow that?

I actually don't see why the kernel should accept tagged pointers to userspace at all. And it seems it should already be checked everywhere otherwise userspace could already make the kernel access unintended kernel memory. I don't see how, if some of them could start to be dereferenceable under some configuration from standard userspace, it would changes anything.

@klabb3 The underlying protocol - ActivityPub - does not have the same limits imposed by proprietary platforms (e.g. Twitter, etc.). Most constraints that exist on platforms like Mastodon, etc., are usually decisions made for a partiocular purpose (e.g. any character limit on posts in Mastodon is becausse the intended function of Mastodon is for microblogging, etc.). Different platforms in the fediverse - that leverage ActivityPub protocol - implement different constraints for similar reasons; namely, choice.

That being said, for your interest on content and less on interactions - if i accurately understood what you're asking about - may i suggest looking into the write.as platform. See https://write.as/about One can self-host this if inclined, but there's also a paid plan thrhough this company...but the gist is that its designed for much longer-form blogging (and other related functions too)...but still leveraging ActivityPub undernath which could be used for interactions if desired...but its core premise is much longer form blogs. I'm sure there may be other long-form platforms, but this is the one that comes to mind for me (at least for leveraging protocols similar to mastodon). Cheers!
That last sentence is so true.

Here are the last 6 years of winter wheat crop reports in the USA [1]. I don't believe that the slight increase in winter 2021/spring 2022 planting in the USA is anything other than a normal variation. I make no claim to know anything about the rest of the world, but I am skeptical that expectations of a Black Sea conflict has anything to do with planting 4 months ago.

PS, you can get even more data, further back in history, directly from the USDA [2], but it is a little difficult to navigate this site. This link [3] might work for everyone, it is a query for acres of wheat planted all the way back to 1919.

More complex than your typical 1-dimensional function of a cam, this cam was "two-dimensional" in its output.

He almost certainly knows if they are the same person or not since he would have needed to confirm that his source was actually an employee but he does not want to confirm that in a way that undeniably makes the identity of his source public. In this case the breach was much worse than initially revealed and internal vs. external is a relatively minor issue. While I didn't read the whole complaint, searching for a few keywords suggest that Ubiquiti is not disputing that their legal department overrode taking appropriate measures to protect customers, the other key point of the initial article (the main point even). An interested reader will effortlessly make the connection between the arrest and the source without it being 100% confirmed that they are the same person and it is quite obvious that someone who was an employee will no longer be an employee after being arrested for stealing from the company, this does not in any way make it sound like a different person. Developer is more specific than employee but not at all contradictory and also does not suggest a different person. As unlikely as it seems in this case consider if the source actually was someone else either in this case or a similar case in the future. Never revealing sources is the safest way to protect all sources. The way the article was written provides all the relevant information without difinitively confirming the identity of the source, just as it should.
There's a sort of sentiment that shows up here on HN -- it's not everyone but it's consistent -- that the problems with replicability are limited to the social sciences, and don't apply elsewhere, which is not true. It's not everyone of course, there's pushback, but I'm surprised and concerned that it persists.

Just last week or so there was a paper in Nature about how fMRI studies -- a modern backbone of neuroscience work -- have also been mostly unreplicable. This follows a litany of other papers showing the same thing. That Nature paper made transparent allusions to genetics which invested tons of money in studies which were also largely unreplicable, with fairly obvious power issues that were ignored. When the replicability crisis started getting attention, there were interviews with pharmacology corporation scientists saying that the pharm industry tends to internally assume that 2/3 of published pharmacology studies will not replicate when applied to the real world. There were studies showing that oncology had similar rates of problems, and so forth and so on.

The social sciences is fuzzy as you say but they also tend to turn the microscope on science itself first. Meta-analysis in its modern form (as opposed to early statistical methodology papers) comes from psychology; this is just more of the same. There probably are differences across fields but I think few fields are immune.

Also, I would push back on the idea that the general public's mistrust is limited to the social sciences. I would argue that issues with climate change skepticism are driven in part by a general distrust of academic findings and scientists, and many of the problems during the pandemic with skepticism about vaccination, masking policies, and so forth were driven by skepticism about biomedical research. Possner said "such challenges do not affect academic confidence in the reality of (say) climate change and Coronavirus"; I was puzzled by this precisely because I couldn't tell if he was being ironic, or pointing these out as areas where there is a contrast between academic confidence and public confidence in those findings, as if to say "well look at how much the public distrusts that; now imagine when academic confidence is eroded further?"

My biggest problem with the linked piece, in fact, is that it is framed around the question "what happens when the public loses confidence in academic findings" when that problem is already here to a big extent. We saw what happened during the pandemic. That's what happens.

Academics to some extent is falling apart, and it's not limited to the social sciences. The problems with misttrust are running deep and I think academic and political communities have their head in the sand, rather than taking their structural problems seriously. It's always the messenger: the irrational public, the muddle-headed social scientists who are exposing the problems, it's never the corruption in academics itself.

If we use price as a proxy for wheat availability, let's not forget that wheat was trading for under $5 in 2019. It was up to $8 before the war began. Now, close to $10. Which means that the war has made wheat 25% harder to come by, so to speak, when compared to before the war, but the pandemic and all that's related to that had already made it 60% harder to come by. The war effects would have been less noticeable if we weren't already pushing the limits.

> What happens when the public lose confidence in academic findings?

When some X accumulates a track record of not working, people give up on X. Maybe then X will get improved, and slowly people will give it another chance.

The OP seemed to be mostly about the quality of the science in the social sciences. Hmm ....

But, in medicine, there are efforts to be careful. E.g., can test a new drug with double blind randomized placebo controlled trials. Maybe that methodology is good enough to be trusted? It appears that I trusted it when I got two shots and a booster from Moderna against Covid.

In math, hmm ..., if there is a claim of solid proof, published in a respected peer reviewed journal, and so far no one has found any flaw in the proof, then some trust can be justified.

The gravitational detection work of LIGO is astounding, and I'm trusting it. And I have yet to check in detail the math of general relativity -- it's on my long term TODO list!

And I trust the claims for the Webb Space Telescope, and the reasoning for its location at a Lagrange 2 point.

So, in medicine, math, and physics, I can have some trust!

For the social sciences, my view is influenced by my wife and brother, both of whom tried those, got Ph.D. degrees, etc.
