Even in big cities I have trouble spending more than this on a single meal. If I'm covering a date or sharing a bottle with the table that changes obviously, but unless you're going to a suit and tie or otherwise haute kind of place then $50 is absurd.
I like all kinds of cars, but come on, you buy one $40K Camry in your life, you're not going to need another one. Regardless of how long you keep it.

Hi, author here :)

> The term "abstraction overhead" is already defined

Interesting, I didn't know that. I was just trying to describe an idea I had in my head, and not hijack some pre-existing term.

> Most of us don't get the luxury of discarding a system and rewriting from scratch. Instead, we make the code we have maintainable. Each of the tools the author reviles is present in the language specifically because using it properly makes libraries and programs more maintainable.

You're right. Re-writing things is a luxury.

> The alternative would be to say that systems in raw C, or assembly language, are more maintainable, which is obvious nonsense.

Well I didn't say that, and I don't agree that it's the alternative, as it's merely a single alternative. I tried to focus on encouraging a skeptical nature when picking language features to use, and tried to demonstrate the idea of applying skepticism with my own personal examples/choices. The purpose of the skepticism is to encourage conscious cost/benefit analysis that takes into account compilation time, but also how easy code is to grok by new eyes.

Pointer compression seems like an amazing method for bytecode optimization in general.

Bytecode optimization is one of my hobbies and I wish I could find a list of all such methods that VM like V8 use.

I could be totally wrong, but this was part of my justification for buying our new servers with AMD Epyc chips and not Intel. Mainly that the numbers made more sense, but also recent vulnerabilities and mediation issues.
Yes. It took two attempts. The second attempt worked, electrically, but didn’t have a measurable effect on the noise reduction, so did not end up doing it.
So I'm stuck in a traffic jam, and google maps is telling me I can take an alternate route to avoid it and save 25 minutes vs waiting in the traffic jam. Something that occurs to me as I sit in this traffic...

what portion of all the other driver's around me also looking at google maps? Is Google Maps telling them to take the same alternate route as me? Are they all going to do it? If they all do it, does the alternate route (which likely can't handle as much traffic as the original route) just became as jammed as waiting in traffic? Or even worse, if they're all going to do what google maps says, would I in fact be much better off ignoring it and sticking to the original route?

It's hard to tell what's imagination/selection bias, but following google maps traffic-jam-avoidance suggestions has seemed disastrous enough to me enough times that I mostly just stick to the original route now. (Of course, one could also imagine using one's own route knowledge to pick an alternate route of one's own without google maps...)

I suppose google maps could be smart enough to tell half the people to go one way and half the other... I kind of doubt it is, but one could imagine a computerized route direction system which, if enough driver's had it, could actually maximize efficiency by sending different drivers different routes intentionally... I'm not holding my breath for it.
The last time I moved I had to throw out a large collection of books. I tried to give them all to numerous organizations and nobody would take them, including a public library that didn't want them (for free). They were all in pristine condition. I love physical books and I just can't stand to lug them around with me when I move. So now it's all Kindle, for better and worse.
I actually have this problem in a work project: matching 1-n point of sale transactions, credit card payments etc to 1-n bank transactions for large companies. Ie “these three credit card payments totaling 300 match this bank transfer for 290 2 days later.” Can confirm it’s difficult and would love any creative solutions.
The OS can update the Intel microcode at runtime just fine as well, and e.g. Linux and Windows offer such updates (like the one described by this very article). So BIOS/UEFI update/involvement is not needed.
Not true at all. Infrastructure can go down leaving a lot of compute at the nodes. If you can power a radio you can power a smartphone.
That's the price range for the Hawaii projects. The cost for the (much larger) Eland and Gemini projects is $35 MWh (previous and [4], respectively).

WRT intermittency, the point of this conversation is that hydrogen generation is a solution: over-provision and generate combustible hydrogen (or ammonia, etc) that can be used later and / or where electricity performs poorly: long haul transport and high-temperature industrial processes.

Agree and am a bit disappointed with all the dismissals.

As a starting point I think I could guess ahead of time that sensory maps might be distorted from the "norm", but

a) It think it would be interesting to see what moves to where and;
b) How much this process differs between individuals; the remapping or densification could be highly idiosyncratic.

Leading to many other related questions from the article like:

a) What are the critical developmental thresholds for all this stuff?
b) Is total area conserved if a person with fingers also uses their feet like this? What happens, exactly?
c) Are nerves in appendages or spinal cord affected in any way by this process? (probably not right? but...)
d) For people who suffer from phantom/ghost limbs, do their maps change over time? How? [EDIT: after a look around it seems like there are some interesting studies of this].

> Denmark has kind of an UBI: a single mom + one kid, no work for past 20 years, gets more than $2300 per month. Such a person has enough money for food, good apartment, etc. All what UBI wants to provide.

> But many of these people end up depressed, inactive, feels like a failure, etc. Many just give completely up.

How would these people feel without the money, though? Presumably this group is at high risk for depression to begin with, and alleviating their material deprivation may well be doing a lot of good, even if their average life satisfaction is still not great. (This doesn't mean there's no better way, but I would be really wary of letting the perfect be the enemy of the good here.)
Excerpt:

Photonic chip fabrication

"Waveguide networks in three-dimensional architecture were written by the femtosecond laser with a repetition rate of 1 MHz, a central wavelength of 513 nm, a pulse duration of 290 fs, and a pulse energy of 190 nJ. Before radiating into the borosilicate substrate at a depth of 170 μm, the laser beam was shaped by a cylindrical lens and then focused by a 100× objective with a numerical aperture of 0.7. During the fabrication, the translational stage moved in x, y, and z directions according to the user-defined program at a constant speed of 15 mm/s. The careful measurements and characterization on the geometric parameter dependence of the three types of junction, such as coupling length, coupling distance, decoupling distance, and curvature, were taken to optimize the performance to form the standard elements."

> Of all the accidents I've driven past on my daily drives, all of them happened on roundabouts.

In localities with few/no roundabouts, the vast majority of accidents still happen at intersections. Intersections of roads are the most prone to accidents (for fairly obvious reasons), with or without roundabouts.

I believe there is research showing roundabouts are actually quite a bit safer in general, but it's possible it depends on various things. But anyway, accidents happen mostly where two roads intersect, either way.
I'm a big fan of interactive fiction (think Zork) where there are no graphics, just talking to a parser.

This is one neat area, where the old Infocom games are well respected (see "Get Lamp" documentary on YouTube) today, but it is well recognized that the technology and text game complexity has reached entirety new heights that have pushed the boundaries forward immensely.

There is still too much use of green. At least for me, I think green = park. I live near the end of a bypass and on apple maps it looks like a big park. I don't think I would want to go have a picnic on the slope of an off-ramp.
You can actually just use a regular function declaration in the middle of arbitrary Python code if you want. Does that count as a multi-line lambda?
Trying to make decisions for the next 30 years is pointless. If you signed a contract that said you'd get a cool million if and only if you had a latte every day and traded your car every 3 years, I guarantee you wouldn't make it.

In fact, I think that's the best life advice that I don't notice people giving - try not to make decisions for multiple decades at a time because you will change over time. The way you know you're young is you haven't realized yet that in "a few" decades you will be old.
It is true and no I don’t think there’s much talk of changing it. There’s also a problem with inconsistent method arguments. Just look at array_map[1] and array_reduce[2]. This is just the one example that bit me the most, but there are other inconsistencies like this all over the language that require you to constantly look things up.

Not a fan of poetry, or, happiness.

Happiness, for lack of a better word, is boring.

Happiness is boring in the same way being angry al the time is boring; people evolved to notice change. Every single one of our senses only works by detecting change.

Take smell for example. Your nose detects a difference in the smell of the air. When I burn things in the oven, I get used to the smell after a while but when my wife comes home she says: 'Ahh, cooking again earlier?'

Taste is the most obvious one. Fast for a month then eat a corn chip. You will taste that simple food so deeply you could pinpoint the field the corn was grown in. Now eat a million corn chips. You quite literally won't even taste the last one.

Put a fan on in your office, you'll forget its on. Randomly have someone turn it off and the difference will be a bit painful that change is so obvious.

Gain 100 pounds, you get used to the feeling of it. Lose the 100 pounds, you'll get used to that feeling too. If you didn't, people who were obese would strive to be out of pain. There is pain in being heavy, but you get used to the feeling of your body.

I have heard a version of "Humans adapt" for my whole life. I think it's more than that. I think it's more like 'Humans ride the wave of change." We are so symbiotic with change we don't even notice that change is the thing we both fight and enjoy.

Why do I rewatch episodes of MASH? Because it's both the same and different each time. I watch all eleven seasons over and over and what happens? I notice nuance. That's me detecting change. It's hard to exhaust the nuance because there is just so much of it. I see patterns, like how Hawkeye acts drunk or how Hot Lips manages her hair.

What is hard is FORCING change. That's the tricky bit. Lose the weight, win the lotto, date your dream girl. Now that evolution that has kept you safe by detecting change fights you because you are way outside your comfort zone and what you are used to.

Subconsciously, many of us, would do the things that will help us get back to safe harbor: stifle and defend against self imposed change.

I think focusing on happiness is a poorly defined goal. I'd say to enjoy happiness but strive to have peace.
That seems less likely than, say, a house fire or a conventional bomb
I'm excited to see if it takes a newer event for this to happen to the US, or if the garbage going on now will be enough.
Risks had not been factored in as likely (like in Japan the authorities have demanded protection against earth quakes and tsunamis, but only to a certain level and they were surprised to learn that over the lifetime of these plans stronger events happen than anticipated) and if anything happens, the companies are simply not insured - other than via the government, which had created the demand and the environment for these reactors. The companies are also not well prepared if larger accidents happen.

Example: Many old reactors never were designed to withstand an impact of a large passenger airplane.

Large passenger airplanes don't fly into buildings. Right? Well, we have learned in the meantime that this scenario is not that unlikely, since 9/11 and for example the Lufthansa/Germanwings pilot, which flew an Airbus into the ground in France killing all passengers on board.

https://en.wikipedia.org/wiki/Germanwings_Flight_9525

One could now just let these old reactors run. What to do with the risk? Well, set up military systems to shoot down aircrafts approaching a reactor site? Adding more concrete as a protection? I'd guess that there were some clever people exploring the options and in the end its just to costly to do something working...

I've had an unprecedented number of salary negotiations over the past two months.

I had multiple offers to choose from and they were all pretty good on the surface. Having "I can walk away if I need to" in the back of my mind made the entire experience more relaxing (on my end).

I stated with "I'm looking at X, Y, and Z companies" in the first interaction with each of the three interviews.

Company X gave me an offer of $AMOUNT in an email (before a formal discussion about salary). $AMOUNT was a really nice bump from my current salary already.

When it came time to talk "how much do you expect" for Y company I told them I had X offer for $AMOUNT and would be interested to know what they could offer.

Y company came back with $AMOUNT + 10%.

I used was up front with company Z about the previous two offers. They offered me $AMOUNT + 17%. Note: company Z was slightly worse compared to X and Y.

I had a meeting with company X and told them about the above. They agreed to $AMOUNT + 17%.

I took company X in the end.

This worked better when Coca-Cola had a near-monopoly. They could get their bottles back and reuse them. Same for milk delivery, which tended to be a local monopoly or duopoly.

Imagine the screams if the liquor industry was forced to standardize on a common bottle for each size.

As a practical matter, automated sorting of different recyclable materials just isn't that hard. The big problem the recycling plant people have to deal with is food and liquids in the recycling stream.

The compound in question was legal in the US until 2011. Bulk chemicals from Chinese suppliers are dirt cheap. I'd guess that both enthusiasts and entrepreneurs built up huge stockpiles before the ban went into effect.

As for authenticity, my impression is that a huge proportion, if not most, of the exotic drug trade is mis-identified and/or mis-dosed. As others have pointed out precautions exist for the careful and meticulous. But let's be realistic, this does not describe 90% of recreational drug users.
That’s clever and pretty funny! Thanks for sharing

> I think focusing on happiness is a poorly defined goal.

If you think happiness is boring or somehow implies not being able to grieve or feel angry, then you are most likely using the wrong definition of happiness. I think happiness a poorly defined word, allowing you to collapse it into a definition that you saw fit enough to justify ranting about change and evolution.
I appreciate the work this author does to compile these posts, but man, every time I visit his site, I get frustrated that there’s no way to stop the map animations to inspect in detail what has actually changed.

Well the other route presumably has a significant throughput. If 1000 car/min are in traffic, and the side-road has a 200 car/min capacity, the first 20% of people to leave the main road will experience no additional traffic.

Now, let's say that the 200 car/min turns to a bottleneck of 100 car/min if it's overwhelmed 10 mins downstream of the turnoff. If google routes >200 car/min to the turnoff, there will eventually be a significant traffic jam: cars will pile up at the bottleneck, and even if waze stops routing to the turnoff at that point, the jam would still travel upwards like a pressure wave until it hits the turnoff.

I'd have a hard time believing it's possible for waze to know beforehand what those throughputs are, so some situations like this must occur.

How is there no practical reason? The practical reason is implied by context. Apple is among the single most profitable companies in existence, consumers vote with their wallets and their wallets overwhelmingly vote in a manner that supports Apple's decisions. It's a very European thing to point at the purpose of a government entity and assume it's true. Helping consumers? If consumers prefer universal cable standards then they'll favor products with cross compatability standards. The only people who benefit from this government intervention are the EU businesses that can't be bothered to examine themselves long enough to find a way to compete effectively. This sort of disconnected legislation is just another reason the EU has lost significance as an innovator, they'd rather settle for a comfortable and unchallenging norm.
