LarsAlereon··on [dead]
This new product called "Memex" does not appear to be related in any way to the previous ones mentioned on Wikipedia. It's just a good sounding invented name.
LarsAlereon··on The Difficulty in Dating Good Men (Aella)
Late to this, but I wanted to wait till I was home and could type on a keyboard:

Overall, it feels like Aella, justifiably, wants to feel like she has passed a bunch of filters for a guy to consider her a high-qualified mate. This is both because she wants the ego boost of knowing she passed all those hurdles, and also because she's more likely to have relationship success with a guy who knows what he wants, has an established filter system, and decides she passes all of them.

The problem is, as you say, Aella is hot, intelligent, and driven as a partner. This means that basically a guy is going to find all of the boxes he's looking at for a first date checked. This is especially true if he's not an idiot and knows who Aella is and did even a casual Google about her first. This all kind of means that honestly, a first date is more about a guy auditioning for her to see if he's her type. Once he finds out that she's interested, that will be when he starts to get into the nitty gritty of "is this a woman who will work for me as a partner?"

Further bonus question, how do you even date someone with a strong online presence? Are you supposed to read their blog posts? Will they consider that creepy, or disrespectful of their time if you don't?

Let's do a technical interviewing analogy. It kinda feels like Aella is an experienced engineer who has written a well-known library. Basically the "interview" is an employer who already knows her qualifications trying to convince her to work for them. She feels offended that they aren't trying to see if she's a good fit for the position...but its immediately obvious she was at least a 90% fit and nobody needs to poke around for dealbreakers, any problems are the kind that are going to be teased out over time.

LarsAlereon··on Tesla accused of hacking odometers to weasel out of warranty repairs
Tesla was the only Western car company serious about making electric cars. Every other company is very clear that they make gas cars, don't want to make electric cars, and will only do so if forced by the government. Consumers only want to buy electric cars, so it's essentially a two horse race between Tesla and Chinese car companies. I'm no fan of today's Elon Musk, but I'm also not a fan of surrendering the car market to China.
LarsAlereon··on It doesn't matter if your app is shit
So a shit app by a famous person is going to get a lot of attention but very few sticky users and fall off the radar quickly. A great app by a random person will build steam over time and become a sleeper hit.
LarsAlereon··on Creating Carbon-Negative Power
I read over the FAQ, seems interesting but kind of overcomplicated. The key principles (as I understand) are:

1. Source biomass that would have burned or decayed to atmosphere in a relatively short time without intervention, such as forestry or farming residues. This lets you say that any Carbon you don't release to the atmosphere is Carbon removal, but these materials tend to be difficult to consistently source and are energy-intensive to transport due to low density.

2. Use gasification to turn the hydrocarbon content into syngas, Hydrogen and Carbon Monoxide. Gasification is nice because you don't release pollutants like heavy metals as readily as regular combustion, and you can easily clean the gas of any pollutants that were released before burning it.

3. Combust the syngas with pure Oxygen in something that sounds like a rocket engine. Burning pure fuel and Oxygen creates much higher temperatures and efficiencies than when the Oxygen is diluted with "inert" gases, and you don't have to worry about NOx production.

4. Separate the water and CO2, leaving a pure supercritical CO2 exhaust stream. This is the part they seem most vague about, maybe centrifugal separation based on density?

5. Use a high-efficiency turbine to extract energy from the post-combustion supercritical CO2. They say this can power all of the other steps including the pure Oxygen production and still be energy-positive.

6. After extracting all possible energy, inject the resulting CO2 underground in rock formations of minerals rich in oxides that can both contain the CO2 and react with it to form carbonates, permanently storing it.

The biggest question marks for me are the process to burn the syngas and remove the water, whether the CO2 turbine will actually be energy-positive given all the energy costs, the energy costs of sourcing and transporting the biomass, and how well geological CO2 sequestration actually works (does the CO2 react with rock before leaking out into the air?).

My favorite CO2 removal concept is pyrolysis, which bakes material to release hydrocarbon gases and vapors which can be refined to replace petroleum or burned for energy, leaving behind Carbon-rich charcoal which doesn't easily break down. When sourced from biomass this charcoal can be a useful soil amendment for farms, or when sourced from waste that may have heavy metals or other toxic ingredients it can be landfilled with much higher density than the source material. It seems like the carbon sequestration of charcoal is much more proven than burying CO2 underground, and its a lot easier to site a waste-to-energy plant near a landfill than an appropriate rock deposit.

LarsAlereon··on Are Plants Farming Us?
This reminds me of the concept of Vavilovian mimicry, where weed seeds gain resemblance to the crops they grow among over time. Eventually the seeds become so similar to a cereal grain that they begin to be grown for their own sake. Oats and Rye were both originally weeds trying to successfully hide in Wheat fields and survive weeding and winnowing.
LarsAlereon··on Lead is still bad for your brain
Yes, it's depositing some lead on surfaces it contacts, including likely the grass on the green. That said, if the tape isn't wearing away and requiring regular replacement, the amounts likely are trivial. A quick search suggests that lead-free alternatives such as Tungsten-based weight tape are becoming available.
LarsAlereon··on Lead is still bad for your brain
Check for reviews that test for lead levels and buy products with low lead. For example, ConsumerLab is one subscription website that does this testing, but there are many others.
LarsAlereon··on Blameful Post-Mortems
Late to reply, but I took some time to consider my thoughts. First, I want to be a little bit angry:

>As a quick aside - I absolutely hate how most people treat incentives. So many leaders act like incentives are the only thing you can expect people to follow. >Hey, my top sales guy sold a $1M deal but did it at -90% margin, but there was no rule against it, so what do you expect? >There is one main incentive that all employees have - act with high integrity or get fired. Stop excusing people for bad behavior because your little point systems don’t cover every case of common sense.

This is completely unacceptable. The idea that someone could ever feel so insulated from accountability for the business priorities they set that they could even imagine getting away with saying something like this disgusts me. "Oh don't do what I told you and paid you to do, ~do the right thing!~"

Second, to try to directly address the problem: this article shows a complete lack of systems thinking. Systems thinking requires more intellectual investment from managers, but is ultimately the only way to get consistently good results. This is something we established by the 1980s so it's really frustrating that I'm seeing people having to re-prove this in modern times. Yes, it's easier to just blame people for their mistakes, but we stopped doing that decades ago because it doesn't lead to better results.

Finally, the reality is that I have never in my career seen a situation that could be made better by applying more blame. The reason for this is because there is no such situation, and anyone who suggests there is so fundamentally misunderstands what we are trying to do that they simply can't contribute to this kind of discussion. When you blame a person you are specifically choosing not to fix the system that actually caused the problem.

LarsAlereon··on Chewing gum can shed microplastics into saliva, pilot study finds
The article mentions there was no difference between synthetic and natural gums in terms of microplastics released.

The part of the story left out of the original title: "...while on an illegal poaching expedition in a protected nature reserve."
LarsAlereon··on Why Coconut Oil Isn't Fit for Pigs – Physical Culture Study
A quick Google search says pigs didn't gain weight from a diet heavy in coconut oil because it's almost purely saturated fat, and animals need a mixture of different types of fats in their diets. Specifically the coconut oil was too low in Linoleic acid, which is an essential Omega-6 fatty acid needed by animals to produce other fats in their body. Coconut oil is a fine source of calories in animal feed when part of a balanced diet including other fats.
LarsAlereon··on Why Vermont farmers are using urine on their crops
That's why they're capturing the urine directly instead of using potentially contaminated sewage solids.
LarsAlereon··on Groceries in the U.S. remain expensive; more states want to stop taxing them
In general sales tax isn't a significant source of revenue for states, to the point where some states don't tax retail sales at all.
LarsAlereon··on Ask HN: Any songs that uses HRTF?
If you search for the term "binaural" you're more likely to find results, including similar questions asked previously on other sites with a collection of feedback. As I understand it professional audio engineers try to avoid elements like this because they contribute to "listening fatigue" when using headphones that can reproduce the full effect.
LarsAlereon··on Small study suggests dark mode doesn't save much power for human reasons
I would expect significant power savings on HDR displays, especially higher-end models with zoned backlighting. I'd expect moderate to light savings on global-backlit devices with backlight powersaving/contrast enhancement enabled. I'd expect zero to negative savings on global backlit devices with powersaving/contrast enhancement.
LarsAlereon··on Y Combinator deletes posts after a startup's demo goes viral
What even is the the point of VC vetting if companies like this make it through?
LarsAlereon··on Ask HN: Is there any appetite for the return of "lickable" UIs?
What if instead of buttons reacting like glass or hard plastic, they reacted like they were full of gel or air depending on where your pointer was? I'm thinking kind of like a fidget-toy UI.
LarsAlereon··on Is this website legit or scam?
Anonymously registered yesterday with a registrar in Hong Kong. Alarm bells are ringing.
LarsAlereon··on Tesla Recalls 700k Vehicles over Tire Pressure Warning Failure
The sensors also use CR2032 disposable Lithium batteries, like those used on PC motherboards for the CMOS settings, but it's molded inside the plastic of the sensor so when the battery runs low the entire sensor has to be replaced. And your tire place forgets even though you specifically asked them to put it on the work order, and you need to go another full tire lifespan with TPMS lights on.
LarsAlereon··on Ask HN: What happened with big tech and KOSA? Why do they oppose it?
To oversimplify, the KOSA is two things: First, a bundle of relatively uncontroversial rules that enhance privacy for minors and let them and their parents better control their experience online. Second, a ban on hosting content "harmful to minors."

The first thing is probably cool and good, and if that was all that was in there nobody would complain. The second thing is essentially the end of free speech on the Internet. At the very least anybody will be able to take anything down with a single report, and at worst it will simply become legally too risky to ever allow user-generated content to be posted.

LarsAlereon··on What Happened? Biden Hanukkah Reception? 12/16/24
I don't see anything like that in a quick scrub through the live stream, do you have a timestamp or are you talking about a different event? https://www.youtube.com/watch?v=JOx3xufEAoM
LarsAlereon··on 2400 phone providers may be shut down by the FCC for failing to stop robocalls
I saw a lot of companies that either recently ceased operations or probably should have never registered in the first place. Real bad actors aren't going to be silly enough to fail to file their paperwork.
LarsAlereon··on Australia's New Firewall IMEI Blocked 516,875 Active Phones Overnight [video]
Since this video seemed low on details, I did some research: The overall issue seems to be that Australian law now requires that, in order to work in Australia, a phone must be able to make emergency calls on the 4G/5G bands that are used in Australia. There isn't really a good way to tell the capabilities of a phone when it connects to the network, so they maintain a blocklist for phone models that don't support this.

The problem is that it turns out there's a lot of 4G/5G phones that fall back to 2G/3G for emergency calls, or calls in general. Owners of these phones thought they were new enough to not be affected by the 3G shutdown, but are being required to get new phones. There are also some phones that don't support emergency calling out of the box, but can be modified to work by owners by manually modifying SIM settings to force enable volte for example. Since the device block list is by model, someone who modified their phone to work is still locked out.

LarsAlereon··on Ask HN: Why did consumer 3D printing take so long to be invented?
It was invented but protected by patents, so it wasn't until those patents expired that companies and hobbyists started to experiment. Early 3D printers hadn't figured out things like layer adhesion yet so parts tended to be too weak to be very useful. It wasn't clear that this was an area for improvement rather than a fundamental downside of the technology.
LarsAlereon··on Why is Mustard Oil Banned in US and Europe? [video]
To save you a click, Mustard Oil is banned because it contains 40% erucic acid, which is toxic to human beings and animals. The legal safe limit in the US and EU is 2% erucic acid, but commercially sold oils are typically under 0.1%. This was set to achieve a >100X safety factor based on tests of infant animals.

The main premise of the video seems to be that erucic acid is not as toxic to humans as has been reported, so current safety standards are excessive and it should be safe to consume mustard oil. Their main argument is that mustard oil is a popular cooking oil in India and is not known to cause erucic acid disease there. A possible counter-argument could be that perhaps the ways it is used there limit total exposure levels. Maybe if it was easily available in the US people would use it in ways that do expose them to toxic levels, such as trying to deep fry with it. Perhaps this is only a risk to pregnant women or young children, which is why the original safety factor was set so high.

For people who want the flavor of mustard oil without exposure to erucic acid, it's possible to mix some mustard essential oil into any neutrally flavored oil such as canola.

LarsAlereon··on The Telltale Traces of the US Military's New 'Bladed' Missile
See also Dense Inert Metal Explosive, which works by mixing an explosive with a powdered non-burning metal like Tungsten. (Aluminum or Iron would burn and contribute to explosive effects.) This causes much more severe damage at the site of the explosion, but the powder rapidly loses energy moving through air so should cause very little damage some distance away. A problem is that there's a "middle ground" where bystanders aren't killed but sustain untreatable wounds loaded with possibly toxic metal powder.

Overall, I think it is good to have tools that enable higher-precision strikes with lower collateral damage. It is also good to have diligent accountability for the use of any military force so it is only happening when absolutely necessary, and in the most responsible way possible.

LarsAlereon··on Ask HN: I accidentally left a microfiber cloth in a pot of greens – safe to eat?
This is going to be impossible to answer definitively because we don't know exactly what materials the cloth was made of and what additives or dyes it may have contained or absorbed. If it was brand new I would be a lot more worried, if it has been previously washed a few times and only used to clean kitchen messes I would be less concerned. In very general terms polyester is food safe and they sell boiling bags made of polyester. Polyamide cooking utensils are advised not to be used above 70C due to potential leaching of contaminants, but there probably simply isn't very much material in terms of weight to create an issue.

Overall, if it was a brand new cloth or had previously been used to clean toxic chemicals like motor oil, you should discard all of the remaining food. If the cloth had only been used food spills and previously washed...I still wouldn't eat it, but I could see why someone who is more chancey with their food might.

LarsAlereon··on The almost-lost art of rosin potatoes
I came to this same conclusion after reading Harold McGee's "On Food and Cooking: The Science and Lore of the Kitchen" as well. Prior to modern cooking science, it seems like a lot of recipes involved something akin to a religious ritual that accidentally did something beneficial to your food. Now that we understand what is happening, we can use modern techniques to get much better results.

It might have been that book that talked about untapped potential for better flavors by making certain sauces in a microwave oven. The basic theory (as I recall) was that the microwaves would selectively heat oil droplets suspended in a watery sauce, and this would better extract flavor compounds into the oil while not heating the overall sauce enough to damage flavors.

LarsAlereon··on The almost-lost art of rosin potatoes
It's basically just deep frying in an uncommon (and possibly not food-safe?) oil.
