maxkwallace··on Blizzard has lost almost 29% of its overall active playerbase in three years
I did this, and I went through the support process to totally delete my account, including purchased content. Sometimes I wish I could still play SC2 with friends, but expressing support for freedom of speech in Hong Kong and the sinosphere is more important.
maxkwallace··on Does LEED Certification Save Energy? Evidence from Federal Buildings
LEED sucks. This has been known for a long time. But instead of bashing it, we should be asking: is there an alternative? If not, how could we create one?
maxkwallace··on Silicon Valley’s Safe Space
There's almost nothing productive in this article so let's try not to amplify its reach by talking about it too much on public social media.

Best way to respond to this is to ignore it.

maxkwallace··on MasterCard to open up network to cryptocurrencies
You're correct, but it is different. There is no free way to accept payments. I personally pay with a 2% cash back card myself. I just hope people have a full picture of the costs and benefits of each approach. Crypto transaction fees are expensive but there are also a lot of hidden costs of the credit system.

I lived in Taipei for a year and almost all transactions there are cash, debit, or bank transfer. You can do a bank transfer to anyone instantly for pennies. Really puts the ACH system to shame. Some things are better than getting 2% back.

maxkwallace··on MasterCard to open up network to cryptocurrencies
To everyone saying "my credit card pays me 2% to use it", no, your credit card charges the merchant 2.3%+ to use it, that gets bundled into the price, and they give you 2% of that as a kickback.
maxkwallace··on California nurses union plans holiday strike over PPE
Nurses, doctors, and other healthcare workers in the US are being taken advantage of right now and threatening a strike is one of the few ways they can maintain a balance of power in the system.

I support the strike and I hope the folks ignoring covid precautions understand there is a limited supply of goodwill and of people who can save your ass if you get a bad case.

Doctors arguably have it worse right now because due to how they're employed, a good number of them have no legal ability to unionize or engage in collective bargaining.

Average med school debt at graduation is roughly $200k. Now imagine you are a recent graduate from residency or medical school, and you have a comorbidity or risk factor for severe covid. Unless you have some outside funding source to pay your debt, you have no choice not to work, likely in a hospital that has little incentive to keep you safe.

Even ignoring tuition, there is a massive opportunity cost to training a doctor, and these are the folks we're relying on to keep us healthy for decades into the future. Situation's pretty shit. Least we could do is lock down until every healthcare worker has been vaccinated.

maxkwallace··on Kandi K27 electric car available in California for $7,999 after rebates
Not true (source: I recently did a bunch of car buying research and a used Leaf was my number 2 choice; ended up not getting it).

These are electric drivetrains (simpler transmission, etc.) so there are fewer things that can go wrong relative to an ICE car. Obv range is limited with a used Leaf but that's not a problem for most city trips.

maxkwallace··on A pure WebAssembly / JavaScript port of FFmpeg
I worry a lot about this but if this is the price of competing with the Google/Apple duopoly maybe it's worth it.
maxkwallace··on Ruby on Rails in a week
Metaprogramming Ruby by Paolo Perrotta has the best explanation of Ruby's object system I've seen.

It's a must-read for anyone working with Ruby, even if you have no interest in metaprogramming. Despite the title, it's a very approachable and widely-applicable book.

maxkwallace··on Hacked billboards make Teslas see phantom objects causing them to swerve or stop
This is a special case of a general class of vulnerabilities in AI models, where an adversary can cause undesired output from the model by constructing input data not represented in the training set. However, it is legit much more concerning than, e.g. the issue of image classification models mis-identifying well-constructed noise as "panda".

This is currently a research frontier for AI so us non-experts likely won't be able to say a ton about it.

I thought this was a good talk on the issue: https://www.youtube.com/watch?v=SS9DMr4VkbY

maxkwallace··on Dear internet: We must ban targeted advertising immediately
Even with targeted ads how often is it that someone actually (1) wants the thing and (2) buying the thing is net good for them and for society?

I'm sympathetic to the argument that ads could reduce information asymmetry, make the market more efficient, and thus count as a social good. The problem is that advertisers' incentives aren't the same as society or the consumer's.

Look at it this way: Google exists. If you know you want something, it's not hard to find online. Ergo, if you often find yourself buying something because you saw it in an ad, what does that say about your rationality as a consumer?

In practice, corporations buy ads to manufacture demand because their products are neither things consumers or society actually wants, nor things consumers rationally choose to seek out.

maxkwallace··on An alternative argument for why women leave STEM
It's partly biological but there are still many existing cultural attitudes that discourage husbands from performining traditionally "feminine" roles/tasks when caring for their kids.

The author's point about being over-critical of sexism is well-taken, but by reducing the sexist attitudes towards, for example, stay-at-home dads, it may be possible to help more women in STEM have fully productive careers.

maxkwallace··on Psilocybin found safe for consumption in largest ever controlled study

maxkwallace··on Why Taxpayers Pay McKinsey $3M a Year for a Recent College Graduate Contractor
On the positive side, I do think that if we repeat this truth enough times we can decrease the "cover my ass" value of consulting and help more orgs make change autonomously.
maxkwallace··on Ex-FDA Advisor Says of Lasik Eye Surgery: ‘It Should Have Never Been Approved’
Thanks for pulling out the data! One problem is that "somewhat", "very", "completely" don't give a good picture of how dissatisfied these 2.7% of patients are. It's possible some of them developed serious dry eye which can be totally debilitating.

This doesn't mean the procedure shouldn't have been approved, it most likely means that folks need to do better patient education and qualification. Not everyone needs to be a good candidate.

It's also possible that these results vary a lot between LASIK docs. I'd expect that some qualify patients more thoroughly than others. Risk for developing side effects can be assessed beforehand, to some extent.

maxkwallace··on Ask HN: What is your passive income 2019?
I mean, it's worth asking, but anyone with a good niche would be smart to not post it publicly unless the benefits of publicity outweigh the risk of competition.
maxkwallace··on React Concurrent Mode
All good points. Haven't read the code so I don't know how deep the similarity goes but the new React Concurrent UI Patterns is at a surface level conceptually similar to Ember's interruptible route transitions, though more fine-grained.

Also really like the new <Suspense> Component! I created a {{render-on-resolve promise=foo}} Component for the app I worked on in Ember back in 2016, and we got a ton of use out of it. If you set up your data layer right, and use it well, it completely removes the need to ever manually manage a loading spinner again.

maxkwallace··on On the Impact of Programming Languages on Code Quality
I can think of selection bias effects both in-favor of more defects and against it.

On one hand, Haskell or Clojure probably attract more academic types who have a reputation for (consistent with my experience) on-average worse-quality code.

On other hand, the barrier-to-entry for these languages is higher so they tend to be programmed by more experienced folks. I assume that people pick functional languages in part because they believe the functional paradigm leads to higher-quality code, so the sample probably cares more about code quality to begin with.

maxkwallace··on Turo and Getaround Get Heat From the Rental Car Industry
Thank you for that! I completely agree with your comment, and I appreciate the attention to detail. I'll edit my post to change "equally" to "equitably" in that sentence.
maxkwallace··on Turo and Getaround Get Heat From the Rental Car Industry
The problem with this article is that it doesn't go into detail about what the "taxes and fees" pay for, aside from airport surcharges. Without knowing that it's impossible to determine who should be paying for what.

Airport surcharges should just be a toll gate (E-ZPass) when you enter and exit the airport. Same for roads, ideally. A single fee schedule for everyone.

Parking shouldn't be free. Someone with 3 cars on Turo shouldn't be penalized any more than someone with 3 cars who doesn't rent them on Turo and just leaves them parked most of the time.

I use Turo and Getaround. With Turo, I always end up meeting or interacting with the car owner. I'm not renting luxury vehicles, but in my experience the owners are always regular middle-class people. From what I've seen, "Tesla fleet" Jason Chan from this article is not representative of the average Turo renter. Except perhaps in niche luxury markets, Turo rentals won't be massively profitable because renters are competing against Zipcar, Enterprise, Uber, etc. and there is maintenance, cleaning, depreciation, etc. you have to handle for the cars.

I think we can all agree that regulations and taxes should be fairly and equitably applied. I'm fine with my Turo charges going up to comply with this. But I don't think this article is very balanced. It spends a lot of time talking about Turo without acknowledging the massive inefficiencies in traditional car rental business models, as well as the big difference in customer experience.

maxkwallace··on Tenants win right to physical keys over smart locks from landlords
To anyone reading this: if this happens to you, please talk to a lawyer. Please do something to protect future tenants, get the landlord's info online. Don't seek retribution just for yourself.

All it needs is a McKayla Maroney "not impressed" meme and it'd be complete.
maxkwallace··on Explaining Sex Rate Changes
Yes, enforced monogamy may be helpful to women in some circumstances. But I think we both know it's not that simple. Sometimes it's better to be a single mom than stuck in a bad marriage with a husband who didn't want that in the first place.
maxkwallace··on Explaining Sex Rate Changes
I tried. I couldn't come up with a charitable interpretation of "harms far more people" that I could respond to in a meaningful way. So I concluded that it was a troll and lashed out.

It'd probably be better if I just ignored the comment. But I think the claim "harms far more people" is absurd if you consider the unequal harms done to women through history, and the fact that they're half the population. The commenter didn't make an effort to engage in good faith discussion with my post so it's unreasonable to apply the same standard to me.

I'm happy to reply to comments like yours though.

maxkwallace··on Explaining Sex Rate Changes
"swipe right, swipe left" acts as a filter but it's not how people choose partners.

People choose partners based on chatting after the swipe and the overall impression/feeling they have when meeting in-person.

The belief that the majority of women on the dating market choose partners primarily based on looks and status is a fiction that's part of a broader narrative insecure men tell themselves to help rationalize the resentment they experience-- and a result of men projecting their own preferences and motivations onto women.

See my other comment in the thread. https://news.ycombinator.com/item?id=19603329

Yes, for the tiny fraction of women on dating apps seeking hookups, attractiveness and status may be important factors. Many men may never have hookups. But the obsession with hookups is a male phenomenon, and the majority of women find them off-putting.

maxkwallace··on Explaining Sex Rate Changes
For sure it's debatable but this is simply not true:

> Studies show that women have the same hard coded visceral, visual sexual physiological response as men

I don't know what studies you're looking at but you're misinformed. Women don't have the same physiological response to visual stimuli as men do.

I don't know what you mean by "doing the same things" but even if we assume that women are doing those things it doesn't follow from that they are the same as men at a sexual level.

Your comment is simply veiled misogyny.
