jplrssn··on The Myth of RAM (2014)
I’m struggling to understand this argument. The size of memory that you can address on any particular hardware is fixed, just like the word size for additions. Restricting yourself to a smaller part of that address space in software won’t change anything about how the address is decoded.

Did you follow the link in the footnote? [0] I thought it made the case for doing extra quite convincingly.

The gist of the argument is that it's worth spending some small proportion of your work time on exploratory work that might or might not pay off, as opposed to doing more "normal" work (another sprint task or whatever).

For me it described pretty well what I'd already been doing subconsciously for some time. I thought it was interesting to see it framed that way.

jplrssn··on Vehicles with higher, more vertical front ends pose greater risk to pedestrians
Insurance won't get you out of jail or pay your fine for you. But your point is valid for civil damages, like getting sued by the family of the pedestrian you just killed with your truck.

I wonder how much of an effect those hypothetical lawsuits have on downstream insurance premiums — anecdotally, it hasn't stopped the F-150 being the most popular car in North America.

jplrssn··on Vehicles with higher, more vertical front ends pose greater risk to pedestrians
I agree that is outrageous.

But I'd imagine most people don't consider the survivability of pedestrians in a collision when they buy a car, since people generally overestimate their driving ability and underestimate their likelihood of ending up in an accident.

So harsher penalties might not improve car designs much.

jplrssn··on Why companies are racing to build the biggest bug farm
Ah yes, the famously extremist BBC and their vegan agenda.

Even ignoring the environmental issues, high consumption of red meat has been linked to a number of adverse health outcomes. Processed meats even more so. [0] But I imagine you'd call Harvard Medical School extremist too?

jplrssn··on Why companies are racing to build the biggest bug farm
Good point. But there are questions around the long-term safety of seaweed additives. And how many farmers would pay for seaweed while methane is free to emit?
jplrssn··on Why companies are racing to build the biggest bug farm
Beef production (as well as meat produced from sheep and goats) is one of the most environmentally costly ways of producing food, because of methane emissions [0]. I don't imagine substituting bugs for grass would make much of a difference there.

I myself would quite happily try a bug-derived Beyond Meat burger or similar.

jplrssn··on Nordic is getting involved in RISC-V
Can you point to something specific in the Arm ISA for embedded CPUs that makes it less power-efficient than the RISC-V equivalent?
jplrssn··on Workers in Sweden Will Expand Strike Against Tesla
Unions generally lean left politically for the same reason business organisations tend to lean right. It would be strange for them to advocate for worse policies for their members.
jplrssn··on New Requirements to Travel to Europe
Not OP, but in my experience they will look for a Schengen entry stamp during the exit control.

Showing e.g. a Swedish passport for border entry and exit, and a US passport for check-in works fine.

jplrssn··on Life lessons from the death bed
Yes maybe. But these deathbed regrets can also be shared by hospice staff [1] and volunteers and the like, some of whom arguably are more likely to spend time with patients who don't have family there.

I don't disagree that many people find personal satisfaction in their work, beyond seeing it just as a source of money. I do too.

Your point about time being zero-sum is a poignant one. Everyone wishes they had more hours in the day to spend doing things they like. But the question is about how we spend that marginal hour, and I think oftentimes it is better spent on family, friends or hobbies than our day jobs.

jplrssn··on Life lessons from the death bed
Great read.

As with everything, balance is key. But I’ve never heard of anyone on their deathbed wishing they’d spent less time with family and friends, and more time grinding away at work.

jplrssn··on Singapore: Right to own a car costs $76,000. And that doesn't include the car
If the cost of owning and operating a car included paying for externalities like CO2 emissions it would already be unaffordable to the middle class. Internalizing those costs is only fair.
jplrssn··on What if we tolerated diseases?
There's pretty strong evidence that policies like subsidised child care in high-income countries lead to higher fertility rates.
