telchar··on Signs you might be a micromanager
Oh yeah, that's some pretty clear obfuscation. It sounds like a PITA to work with code like that.
telchar··on McDonald's is adding plant-based burgers to the menu
To be fair, your first link doesn't say that vegerable oils are bad for you. It just says that the Omega-6 fatty acids in them, if not balanced out by additional Omega-3s from other sources, cause health problems. So vegetable oils aren't inherently unhealthy and can be consumed without problems as long as the need for Omega-3 is respected.

I'm curious, how would they obfuscate code and how could you tell?
telchar··on Ditch the Batteries: Off-Grid Compressed Air Energy Storage (2018)
I'll admit this article describes a much less bad system than what I envision when someone mentions compressed air energy storage.

On a side note, I wonder what the state of research is on reducing the embodied energy in li-ion battery production. The mentioned figure in the article is surprisingly high (2-10 times the total energy the battery will store - presumably they mean over its lifetime), which now that I think aboute it, squares with what I have seen elsewhere on the embodied energy of electric car manufacture.

telchar··on A housing industry of endless one-offs is holding our society back
They need to be made out of something unless you like a very open plan. In the past they might have been made from wattle and daub, or you could use studs, paper, whatever you want since they're not structural.
telchar··on Why are Amnesty International monitors not able to observe the Assange hearing?
If you want to name a country that has rule of law, in your opinion, it works make your point stronger. The US isn't a particularly good example of the rule of law right now, true, but I think you would be hard pressed to come up with an example that passes your apparently stringent purity test.

If you can't point to such examples, your point comes off as trivially weak.

telchar··on Why are Amnesty International monitors not able to observe the Assange hearing?
In this case, those in the US most alarmed by Russian interference in the US election are mostly the same people who oppose US interference in foreign elections too. The people who supported the invasion of Iraq, for example, are mostly happy to turn a blind eye to Russian interference now.

Remember in every country which does things you don't like, there are people who feel as you do. In this case those people are getting the shit end of the stick.

telchar··on 2.5M Medical Records Leaked by AI Company
"The principle with which we are now dealing is that one which is called Expediency. The usage of this word has been corrupted and perverted and has gradually come to the point where, separating moral rectitude from expediency, it is accepted that a thing may be morally right without being expedient, and expedient without being morally right. No more pernicious doctrine than this could be introduced into human life."

-M. Tullius Cicero. De Officiis. Book II.

telchar··on Science is the belief in the ignorance of experts
As an aside, you're using the word 'populism' like it is the same thing as demagoguery. Populism isn't always dishonest and anti-intellectual, just like elitism (its antipode) isn't always honest and benign. I think using populism that way is throwing the baby out with the bathwater. Populism can cleave to rational well-researched ideas in the face of an elite establishment that is opposed to them, although since it is often used dishonestly it's something to be wary of, it shouldn't be rejected on its face in all cases.
telchar··on Reddit's website uses DRM for fingerprinting
That doesn't really help much. Most enthusiast subreddits are full of posts that are just "look at my [basic standard hobby gear] picture". Even those places are overrun with this.
telchar··on Nobody reads privacy policies, senator wants lawmakers to stop pretending we do
In spirit-of-the-law terms (maybe letter of the law too), I'd argue that privacy policy is not a contract. A contract requires a meeting of minds. It's well-known that privacy policies are rarely read and to most people, incomprehensible or unreadable for simple lack of time in the day. That they are binding contracts is a fiction that the legal system just hasn't seen its way through yet.
telchar··on Nobody reads privacy policies, senator wants lawmakers to stop pretending we do
If companies expected and wanted users to be informed, the standard "we've updated our privacy policy" would be accompanied with a detailed list of changes or some sort of friendly marked-up change log. I have never seen anything like that from any company, so I have a hard time believing privacy policies and TOS are meant to be informative.
telchar··on Woodworking for Engineers
I recently went to a woodworking show in the mid-Atlantic region. There were some masters there teaching classes who seemed very concerned about traditional woodworking skills dying out - from the average age of attendees I can see why - and some of them take on apprentices still. A show like that would be a good place to look.
telchar··on Amazon’s New Competitive Advantage: Putting Its Own Products First
I think the depth is inversely proportional to the utility of search - the better I can search for the combination of features, price, etc that I need the less deep the shelf gets. The endless generic white-labeled junk plus poor metadata really makes the problem bad though.
telchar··on For experts who study coronaviruses, a grim vindication
You seem to be very low on your Ebola numbers[0]. Is that based on a super-strict definition of "confirmed"?

telchar··on Why are Soviet math textbooks so hardcore in comparison to US textbooks? (2017)
In my experience, it's easy to think one has understanding without actually understanding. The process of applying that tentative understanding to a problem to test it is essential to figuring out what the flaws are in the tentative understanding so that real understanding can eventually be achieved. Once it gets to the point that a person can crank through problems without significant errors, then I think further problems don't do much good except as an occasional refresher.
telchar··on Pollution from tire wear is worse than exhaust emissions?
A study linked last time this came up on HN indicated most of the particulate pollution is "resuspension", or previously generated particles kicked up by the car passing. It makes sense to consider in some cases but I think it's misleading to quote those numbers in some contexts, leading to confusion like this.
telchar··on What happens to a mail-order mattress after you return it
I paid a little extra (~$600) for a foam mattress manufactured in California. I figured there is a lower chance of harmful offgassing than the cheaper Chinese mattresses like Zinus. I don't have any way to test that though.
telchar··on Bloomberg bankrolls a social-media army
Vote for the candidate who doesn't make you seriously question whether there will be another election in 4 years?
telchar··on The new business of AI and how it’s different from traditional software
Bad analogy. Data science isn't manual labor. Ask yourself, does an artisan woodworker want the shop to buy a CNC mill that they'll be obliged to use to justify its cost, knowing that they can be replaced more easily as a machine operator than as a skilled artisan?

They would probably rather advance their skills in woodworking than as a specialist in XYZ Woodco button-pushing.

telchar··on SpaceX first stage landing failed for Starlink-4 launch
It's hard to appreciate the scale in person too, it doesn't look real (I was there). Like the other poster said, it's surreal. But the sonic booms help remind you the boosters are large and moving very fast.
telchar··on Ask HN: What are the underrated newsletters you like reading?
The Orbital Index (orbitalindex.com), highlighting interesting developments in space.
telchar··on The Pacific Ocean is so acidic that it's dissolving Dungeness crabs' shells
Freshwater animals aren't really relevant since they aren't going to do any good for life in the ocean if the animals that evolved for PH of 8.1 can't survive due to decreasing alkalinity. If the ocean life can't adapt it very well could be a harbinger of the apocalypse. Not saying it will, but your assertion that it isn't is also a false bromide.
telchar··on Uber stops upfront ride pricing in response to California worker law
That's one of the reason people hate taxis, and why people jumped to Uber instead. Who's to stop the driver from taking the long route, and how am I supposed to compare options if I don't know how much it will cost? Pull out a pocket calculator and a map?
telchar··on Uber stops upfront ride pricing in response to California worker law
Does the law say you can't do upfront pricing? Surely the company could just eat the difference in the situation you raise? To me this seems to be Uber's way of passing on any extra cost and risk to customers rather than risk any of their own skin.
telchar··on Apprenticeships Beat Classrooms
That's what makes PhD work a good example I think, because a low-paid job that can be quite abusive describes apprenticeship very well. It's Inherently reflective of the quality of the master. If the master is an abusive drunk, the apprentice is going to have a bad time. Also the apprentices historically had to do much grunt work like (in blacksmithing, to choose a profession) churning out nails. Produce or perish.

I think there are advantages to bringing back parts of apprenticeship, but it is not a system without flaws or weaknesses.

telchar··on Car-Free Streets Will Soon Be the Norm
An e-bike would go a long way to materialize the convenience promised by biking. Prices are coming down quite a bit as well. Maybe look into that, they're fun too.
telchar··on Car-Free Streets Will Soon Be the Norm
Parking lots at the border is, in my opinion, much better than parking garages in the center. At least that way the city streets won't be clogged by people coming from out of town. After they get to the city they don't need the cars, so leave them at the edge.
telchar··on Oakland shows how to expand housing supply: tell developers they can build homes
You're talking out of both sides of your mouth here. You say that kitchens and bathrooms are the "big cost items" yet here you say that omitting or scaling them back doesn't save much. How can both things be true?
telchar··on Air pollution causes brain structure changes that resemble Alzheimer's disease
That paper has some flawed assumptions, I think. For one, they tie resuspension linearly to vehicle weight, but say that it's related to the vehicle's wake. It seems that they're confounded by the typical relationship of weight and size (therefore wake). But electric vehicles while heavier, are typically the same size as ICE vehicles. Thus they might break the assumption that greater weight means greater resuspension.

The paper says that resuspension is the largest part of non-emissions particulates, so we have lowered brake sources (because regen means less pad wear) and lower emissions, and probably not greater resuspension. Maybe tire wear is higher. Put those together and it seems like electric vehicles should come out ahead, particularly if we're talking about diesel vehicles.
