mostly_harmless··on Canada welcomes EU proposal to become 'associate member'
what does that mean? People should never have friends because some people are jerks?

Self-isolation (whether a nation or a person) is not a good solution to hypothetical bad actors. Society is built on cooperation and trust

mostly_harmless··on Growing proof that autonomous cars save lives
skewed in the sense that 2-5% of the population is a terrible driver and 90-95% are sufficient.

It's an outlier effect. Like the mean networth of a USA household is around $1 million dollars. But that figure alone gives you an extremely poor view of overall financial health of the median american.

mostly_harmless··on Growing proof that autonomous cars save lives
no. As per the link, that is 64% of <<distracted driver>> fatalities were "lost in thought". not 64% of <<all>> fatalities. Distracted driving is the 2nd or 3rd largest factor in fatal accidents (behind speed and alcohol I believe). Somewhere around 20-30%. Though this is for fatalities. Distribution is going to be way different for just hospitalization or property damage accidents.
mostly_harmless··on Growing proof that autonomous cars save lives
Fatality data is extremely skewed. 44% of drivers aren't using a seatbelt, 29% are speeding related, I recall alcohol involvement being about 30%, though it's not listed in the link I checked. About 20% of automobile fatalities aren't in cars but are pedestrians or bicyclists struck by cars (add another 16% if you want to include motorcyclists, though only half of which involve another vehicle). I recall the percentage of vulnerable road user deaths is much higher in urban areas.

The majority of drivers are good, but some drivers are really bad. Life in USA is extremely car-centric and taking away a license is often infeasible and the offender usually drives without their license anyways. If anything, I'd like autonomous cars to give a legal out to remove bad drivers. You get a DUI, or commonly speeding? You may only take an autocar.

Spelunky and Terraria do a good job with Procgen.

Spelunky uses handcrafted chunks that are connected together like a puzzle. Each generation feels interesting because each chunk is interesting and they are just strung together into a unique maze.

Terraria does a similar thing, where all the things that matter are hand-crafted. Bosses, items, layer details, progression. The map and cave system is generated but the caves tend to string together hand-crafted experiences and hand-crafted monsters. Many areas are generated, but in a unique style for variety. And there was still a fixed progression in the background (ore and boss progression). I think its in a big contrast to a similar game like Starbound, where all the weapons and creatures and maps were procgen at first, and it felt very '10000 bowls of oatmeal'. Terraria vs Starbound is the most like-for-like comparison I've seen for "procgen done right vs wrong"

mostly_harmless··on Decathlon Germany adds Wero payment option to decathlon.de website
Can confirm they do this in Canada too. Though I'm not sure they have much of a presence outside of Quebec.

It was very cool to try, and very much a "why doesn't everyone do this?" feature. I've never seen it anywhere else.

mostly_harmless··on Show HN: I've built a words game based on binary search
7 letter words are too long. I'm finding trouble thinking of any.
mostly_harmless··on Waymo robotaxis are now giving rides on freeways in LA, SF and Phoenix
I'll add on that speeding is the biggest contributing factor in accidents. And accident outcomes get exponentially worse above 30mph. For every 10 mph of increased speed, the risk of dying in a crash doubles.
mostly_harmless··on Steam Machine
> you can wake your Steam Machine without leaving your couch. [using the built in steam controller wireless adapter].

This one simple thing is the only thing that makes my SteamDeck+Dock feel like a second class console. So far they only claim it's for the Steam Controller, but I'd be great if it worked with the handful of 8bitdo or Switch controllers I've been using.

mostly_harmless··on Dyson, techno-centric design and social consumption
I don't hate Dyson because it's trendy, I hate Dyson because my $700 vacuum wont pick up cheerios; a common spill with toddlers.

Somewhat related: I wanted to track watch time, and perhaps set a time limit with Plex and HomeAssistant. Has anyone come up with a solution I can cheat off of?

It also ignores that they often own the suppliers. "Woops, our supplies raised the price, so we need to too."
mostly_harmless··on The Great Pacific Garbage Patch Can Be Cleaned for $7.5B
Maybe a dumb question, but why? I don't like that it exists, but isn't it self-contained? The main reason for cleaning it up seems to be quoted as [1], which oversimplfies to 'animals might eat plastic, and it affects them', and it will make microplastics. But these problems seem to be localized to the garbage patch. I could see it as a asbestos situation where its only problematic if you disturb it. Ongoing dumping seems to be a bigger problem as it's not localized.

I feel this way for photography, about filtering. If you take 1000 photos, only show people your 20-50 best. Now you are a good photographer.
mostly_harmless··on The standard American household is now a millionaire, according to the Fed
The most important part is this article is that this is the mean.

The median net worth is $192,900 (as per the article).

This just shows there is an extreme wealth disparity.

mostly_harmless··on US economy returned to growth last quarter, expanding 2.6%
Yes, but not directly. If you listen to the last FOMC meeting, Powell mentions there will likely be significant weakening of the labor market and a rise of unemployment. As well as his famous "there will be pain" remarks.

I don't think he directly said "he won't stop until" though.

mostly_harmless··on The anti-inflation pivot of 2022
supposedly about a 1/3 of mortgages are variable in Canada. But more importantly, fixed mortgages are almost all 5 year terms (or less). That is, every 5 years you have to renew your rate (even though the mortgage amount is for 25 years). That means every year, about 20% of homeowners are updating to the current fixed rate (assuming an random distribution of purchase date). Perhaps a big chunk renewed early in 2020, but by 2025/2026 all mortgaged homeowners will have a new higher rate.
mostly_harmless··on Stanley Druckenmiller warns the stock market will be ‘flat’ for an entire decade
I don't know if it's moores law. except for servers, CPUs are mostly running near idle.

My intuition would say tech saturation would make more of a difference. That is, worldwide pretty much everyone have now has adopted a computer and all businesses have automated the low hanging fruit.

mostly_harmless··on One year on, El Salvador’s Bitcoin experiment has proven a failure
My theory behind this is there are many BTC holders with cap gains (or assets acquired through illegal methods) that can't easily cash out, and El Salvador's BTC support was a grab at capturing tourist revenue through state sponsored money laundering.

Through that lens, it would be interesting to see if there was any anomaly in GDP, luxury goods sold, real estate sales, or tourism in the country.

mostly_harmless··on Estonia clocks fastest inflation in the Eurozone at 20.1 percent
I think what's missing here is in case 1, it's not just the amount of money, but how much money is chasing each available good. You can imagine if the money supply doubles, a loaf of bread can be the same price as before if there are twice as many people demanding the same portion of bread (for a very crude approximation)

Or to put it another way, maybe case 1 is demand-side inflation, and case 2 is supply-side inflation.

For those questioning the feasibility, 100% electric school buses are already on the road in Montreal. I see them frequently, and they seem to handle our crappy roads and winters fine.
mostly_harmless··on New Secret Service report details growing incel terrorism threat
I think with everything that is going on, everyone should be aware of the Russian book "Foundations of Geopolitics"[0]. It is a textbook that basically gives a blueprint on how they should take over the world. On how to deal with the USA:

* Russia should use its special services within the borders of the United States to fuel instability and separatism, for instance, provoke "Afro-American racists". Russia should "introduce geopolitical disorder into internal American activity, encouraging all kinds of separatism and ethnic, social and racial conflicts, actively supporting all dissident movements – extremist, racist, and sectarian groups, thus destabilizing internal political processes in the U.S. It would also make sense simultaneously to support isolationist tendencies in American politics"

mostly_harmless··on CEO demanded all employees return full-time to the office. Only half showed up
One thing I haven't seen mention much is real estate. The "back-to-office" militants are usually corporate, and there's a lot of corporate money tried up with office real estate that would lose a lot of value if everything shifted to WFH forever
mostly_harmless··on Ask HN: What do we do with cash now that inflation is a risk?
This only makes sense if you have positive-risk-adjusted-return investments you've been waiting to make. If you already have too much cash with no where to put it, borrowing more cash makes no sense.
mostly_harmless··on Possibility for strong high-latitude cooling under negative emissions
"all that kenetic energy released when jumping off a building was formerly potential energy stored when walking up the stairs. How can that lead to life destroying conditions when life previously held that energy?"

The rapid change in environments can make many species no longer suitable for their environment leading to extinction. Sometimes they can transfer to a new environment, or sustain at a degraded efficiency, but often they cannot if the environment change is drastic enough. This is happening everywhere all at once.

mostly_harmless··on Possibility for strong high-latitude cooling under negative emissions
There's a huge difference between warming over a couple tens of thousands of years (natural rate), and warming over a couple of decades (our current trajectory).

That difference is the eradication of much of life on earth that is unable to evolve to a new environment. For example, insect numbers worldwide are drastically lower than decades ago, and insects are required for almost all pollination of plants and a key source of food for small animals. The "food chain" collapses if there is no first chain.

Even a partial loss of ecodiversity can lead to further problems later.

Our efforts are certainly not in vain.

mostly_harmless··on Show HN: WAPM – WebAssembly Package Manager
It looks like this is focused on primarily on executables, but there is a mention of libraries.

I was looking into WASM libraries recently, specifically WebAssembly Interface Types (WIT), and my conclusion is that WASM libraries are experimental and poorly supported right now (unless you only have i32/i64/f32/f64 as parameters and returns).

I couldn't find any elaboration in the documentation on libraries, what level of supported does this have? Is interface type implemented?
