> This pseudoscience idea that "dopamine equals motivation" or that you can modulate your entire motivation/reward circuitry by playing games to modulate dopamine is an egregious abuse of the science.

I suggest you listen to the Huberman episode. Of course, he never claims something as simplistic as "dopamine _equals_ motivation", but there's wealth of evidence that he cites in the episode that the two are intimately related. The second part of your sentence is actually pretty close to the truth rather than an egregious abuse of the science, though it depends on what you mean by "playing games to modulate dopamine". The entire episode is about the topic, and I strongly recommend it.

> You can't reduce everything down to one, singular chemical in the brain. Human psychology and motivations are complex and not a function of singular chemical "levels" in the brain.

I'm pretty sure you won't find any instance in the episode where Huberman claims to reduce everything down to dopamine.

> there must be a vast gulf in skill level between me and the average hn poster

I suspect it's much more a time gulf than a skill gulf.

I love AoC as well and don't so much burn out but find that after a week of coding for fun in the evening a mountain of real world responsibilities start piling up, especially around the holiday season.

When I was in undergrad I had virtually no family responsibilities during December and a large amount of free time when classes ended, so it would have been easy to spend hours a day on AoC. Many younger, single professionals are likely in the same situation.

I think for most adults with family responsibilities and full time jobs (and likely a range of side projects that also need attention) that first week of December is a rare lull, and a great time to solve a bunch of fun code problems. After that more and more other things take focus as the holidays approach.
There's been a rash of this all over SoCal. It's very professional. They hit a fixed number of cars of a given make/model in just a specific year range (presumably so they can do it quickly), then move on to a different city. By the time they swing back around they are hitting a different make/model (though as TFA mentions, it seems to always be Priuses and Ford trucks).
I came here to say that and had that they have a bot to notify people who might be on the wrong reddit. It seems to do a good job as those post are rare nowadays.

A similar bot (using a naive bayesian classifier and a few examples) should be easy to build for the /r/kafka reddit.

Unfortunately, since these concepts are presented through a religious lens, Maya renders many people unable to even consider (and therefore falling back to binary heuristic thinking, not realized as such) the valid neuro-scientific concepts contained within.

A simpler, secular version of the same general idea:

Less in the self-help context, more in the process context, one I often appreciate for its simplicity is this:

> It’s a mistake to evaluate any code as static.

Definitely agreed. By software evolution, I was referring to your mentioning “goals drifting apart”. Code is always dynamic, constantly maintained, but goals don't always drift apart. When they do, it's because of unexpected circumstances. Doing a right abstraction for unexpected cases is almost not possible by definition. (It is, but in that case one falls into the more dangerous trap of premature abstraction.)

> We can’t debate or say anything useful about whether an abstraction is better than duplication without looking at specific cases

Agreed again. I'm aware that I'm overgeneralizing at the cost of neglecting any nuance. Once, I encountered nested loops iterating over a data structure and performing simple operations. I was abstracting these loops into a static method. Unfortunately, not all loops were exact copies. Some loops defined new variables while some reused the existing ones from surrounding code, some had different loop bounds while some performed the same functionality by breaking the loop inside an if. Some loops did a different job, but looked the same.

I had to be sure that each code piece was doing the same thing by manually inspecting and testing it (there were no automatic tests and code wasn't structured well for testing purposes). If these nested loops were abstracted in the first place, there wouldn't be any doubt whether they were doing the same thing or were slightly different. All of them would be the same function call. When the goals drifted apart, it would be easy to identify the points of evolution.

Thanks for your replies. They broadened my perspective.

I don't know exactly how this is done for cats but I've gotten into some backyard metal extraction before. If you have lax safety standards and some ingenuity a lot of precious metal extraction can be done with reasonably inexpensive and small equipment, it's the kind of thing you could set up in a rented garage for probably under $10k in equipment if you're thrifty and clever. https://www.hindawi.com/journals/jchem/2019/2318157/ suggests a process, basic technique seems to be to extract the core, crush it, and then chemical separation and precipitation using reasonably easy to get reagents. And given that they talk about it as an eco-friendly method I suspect that isn't the easiest way.

> The popular solution, that is almost free, is simply moving the catalytic converter from mid-tailpipe to directly connected to the engine block. Essentially the CC is surrounded by the engine block itself on all sides, and you have to disassemble the entire engine from above to get to it.

You are aware a catalytic converter is a wear part that is a component of the exhaust system, right? You want a block disassembly to replace a part so understood to be a wear part it’s covered by US federal warranty to 80,000 miles? You just added at least eight hours of labor — which in major metros can reach $300/hr — and risk to a one hour job. There are absolutely zero reasons to open a block unless the engine itself is imperiled or under inspection. Blocks are notoriously difficult to reassemble to spec and the idea is to avoid opening them as long as possible.

I’m aware manufacturers are burying cats closer to the block but that’s universally thought to be a bad idea for owners and a great idea for mechanics. Now you want to put it inside the block? Please, please, please don’t design cars, and let me know which manufacturer came up with that genius solution so I can avoid driving one of their vehicles for the rest of my life. The rest of you should as well because all that “fix” does is octuple your repair bill for fixing a bad cat and risk your engine for doing the same.

No disrespect, truly, but after over a decade of being a tech, that might be the stupidest idea I’ve ever heard in vehicle design. And all of that for what, to avoid theft? What makes you think they won’t just steal the car instead if the cat is buried in some Fort Knox inside?

We all know where the stolen cats go. Why not start with those places rather than lobby for some John Deere type screwing over on self repair?
> Going further, the more granular your mental model (I.e the more abstractions), the higher the chance that other teammates’ mental models will differ.

Agree to an extent. What I tried to explain in my other comment is that having full abstraction here, half-way abstraction there, and a different partial abstraction somewhere else also weighs on the mental model you need to have of the codebase.

That might be an argument to muster the dilligence and discipline to have more of the same abstractions consistently for similar concepts (excepting those that are obviously superfluous, of course).
> This is absurd. The "gene pool" has nothing to do with people's sense of ethics around having kids or not.

To think that fertility -- one of the key issues in evolution -- would not be influenced by genetics requires a massive detachment from reality as well as lack of awareness of current knowledge about genetics and human behavior.

Note that we have data on this, and a good rule of thumb is that most everything is about half genetic. This includes likelihood to have kids. Why? well, things like sperm counts, and personality traits are influenced by genetics, as are things like tendency to be religious[4]. Values are also strongly influenced by genetics, as is income and intelligence[5], all of which is correlated with decisions to have or delay having children. Similarly the duration of the reproductive lifespan of females is influenced by genetics[2] - something very important as women delay childbirth:

The most recent GWAS conducted in ∼370,000 women of European ancestry identified 389 independent signals explaining ∼7.4% of the population variance in age at menarche (Fig. 1), corresponding to ∼25% of the estimated heritability[2]

And even the decision to delay childbirth is influenced by many factors that have a genetic component.

> We don't have a "don't have kids" gene that can get outcompeted.

An international research team, including the Norwegian Institute of Public Health, has found twelve genes that may help determine why some people have children at an early age, while others remain childless.[3]

Amazon has really turned a little more hostile to Third Party Merchants in the last few years.

In 2012/2013, I was doing FBA on damaged cargo/insurance buyouts (If a truck gets into a wreck, 99.9%, they can't use the goods on the truck, so, Insurance companies will sell them for pennies on the pound. Yes, pound) when I found a company that was selling a trailer full of LG 27" monitors for what would equate to about $18/each. I had some office and self-storage space and a SUV, and would literally take 10 them from my self storage unit every day, take them to my office space, test the monitor out, open the back to inspect for damage, and then repackage everything in the box and sell them as Used/Tested/Refurbished depending on what I needed to do to get them working again.

My biggest complaint was that when someone would return a monitor, it'd never make its way back to me -- as in, it always looked like someone would never return the monitor. I'd set calendar reminders to follow up with Amazon Seller Support, and I'd always get the money credited back to my account.

I've watched the fees go up and up (when I was doing FBA, my Amazon fees would cost me around $10, shipping included, per piece. Today, the same fees would run me around $30/unit per device: my item is considered 'oversized')

As someone on the Seller Forums mentions a few different times -- you aren't amazon's customer, the end-user is. Amazon is just a channel for selling your goods. Unfortunately, dealing with Amazon as a channel partner is just basically russian roulette -- no matter how well you can describe your problem, you're working with a team that just doesn't care.

I've had offers from the same trucking insurance company over the last few years -- even a truck load of PS5's this summer -- but, didn't really want the headache of dealing with Amazon, so, I've turned the offers down.

Can someone answer the General Relativity concerns regarding this?

Imagine the same loop as Derek setup in the video, but where it extended into next galaxy (say 1 light year away). In next galaxy there is another switch - we don't know if the position of that switch is open or closed...

Now when Derek connects his switch and light nearly instantly turns on...this is obviously telling us information regarding the switch 1 Light Year away. How does this not violate General Relativity since seemingly that information is traveling faster than speed of light?

since you are at the execution phase, i would do the electron app first to get things going. then consider a macOS native.

i may be overestimating everything involved in releasing software for macOS. but i have played with swift and made a few local apps and found it difficult to put desktop apps together. you will find plenty of iOS resources though. they were still porting some of the SDKs to swift from objective-c when i was playing with it.

people who know objective-c and the macOS SDKs beforehand would have better luck.

with electron, i suspect the open-source community would have solutions for most issues. or tell you the limitations. you will know then what you are gaining with a macOS native app.

that's what i would do...

>Spotify is a perfect example of a tech company that gives absolutely no fucks for the preferences of their paying customers.

I think that is a larger problem across the industry. And here is an unpopular opinion especially on HN. Tech is dominating every field. Tech is dictating trends. And Tech company are making consumer products but doesn't understand consumers. It is exactly the same on Apple Music at launch when they decide to not include a Loop button because it was all about the "Next Song".

I felt Spotify, or arguably Apple has made the business case for Streaming Music ( or not since they dont make much money ). But in terms of product or UX they are not any better.

Having said that I still think Spotify is far better than Apple Music. And Shuffle works for long playlist and not on Album so I am perfectly fine with the decision.
