krschultz··on Yoga: A cross-platform layout engine
AutoLayout basically directly exposes that algorithm and all of its complexity to the developer. That makes it the most powerful, but also the hardest to learn. Flexbox is a nice middle ground where you can express most things in a sane manner, but it's not the single layout engine to rule them all.
krschultz··on Four Million Commutes Reveal New U.S. 'Megaregions'
I wouldn't muck with the east coast states much. The borders might be off by a little here and there, but not by much.

However most of the western states were last carved up in 1850s. I don't think we need to redraw them every 30 years, but maybe every 150? Considering the last time we adjusted California's bounds the transcontinental railroad wasn't built yet.

krschultz··on Downside of Lower Manhattan’s Boom: It’s Too Crowded
Or build the street up 1 level and have an underground level on the current street - isn't this basically how Chicago built sewers?

The requirements around scaffolding are kind of an annoying middle ground of rent seeking. You are required to put them up, but then you aren't charged enough for them while they are up to incentivize anyone to take them down. In some cases the scaffolding goes up and the company that owns it goes out of business or the contractor goes bankrupt and it just gets left there.
krschultz··on Base-122 – A space efficient alternative to base-64
I would be interested to learn more about those concerns. My "default" setup these days is HTTPS & gzip everything, but I can't say I've read any white papers on the security implications of that.
krschultz··on Freelance Isn't Free Act Passes in NYC
You can get freelancing contracts without hiring a lawyer. The freelancers union (the site linked here) has one such example.
krschultz··on Fewer than 3% of cars sold in the U.S. have manual transmissions
I'm sure this is a joke, but you actually shouldn't ask anyone in an interview if they own a car or how they intend to get to work.

Best explained by video. There are many on YouTube, this one happens to have a lot of views. https://www.youtube.com/watch?v=EAi0fes4OC4
krschultz··on Trump-Supporting CEO Kicked Out of Y Combinator Startup Incubator
Why? Buzzfeed actually has some well written pieces. They pay the bills with the listicles, but they use that money to fund journalism. Andrew Kaczynski was great this whole election, and was at Buzzfeed until CNN recruited him in October.
krschultz··on Vancouver plans to tax empty properties 1% of their assessed value
You can get a mortgage on a physical residence but not a fund. You can buy insurance on a physical place but not a fund.
krschultz··on Vancouver plans to tax empty properties 1% of their assessed value
You're making a huge assumption that capital controls are the cause. It's more likely that people believe real estate is a better investment than currency, stocks, precious assets. Or perhaps they just want to diversify their holdings. I'm considering buying some investment real estate, and it has nothing to do with capital controls.
krschultz··on Vancouver plans to tax empty properties 1% of their assessed value
I'd say a more specific definition in this case is "people that are using real estate as a place to park money rather than as housing". In many cities like Vancouver, New York, and Miami, the money often is coming from foreign countries. With housing so limited, that has a real impact on people that live in these cities, and the benefit is provided to people that don't even live here.
krschultz··on Ask HN: Do you still use UML?
I'm an extremely visual person so for me diagrams are incredibly useful. I'm constantly drawing class diagrams and communicating via pictures. I want UML to work so bad.

Unfortunately, I think UML suffers from all the dysfunctions of a language designed by many stakeholders. It's just not intuitive, so you have to remember the details. I start practically every handwaivy whiteboarding session with the disclosure "this is not UML but ...".

As with many "standards", we've sucked the oxygen out of the room by saying this is the one true way. I very much prefer having multiple competing specifications and letting the winner shake out. I imagine if we hadn't prematurely standardized on UML years ago, visual programming and diagramming would have evolved in exactly the same way regular programming languages have evolved. Why do I have 30+ choices for what to write my web server in, but only 1 seriously spec'ed out language for drawing it?

krschultz··on Firms envision ways for New York to absorb 9M residents
Uhhhhh https://en.wikipedia.org/wiki/Nikon_at_Jones_Beach_Theater

The beach existed long before Moses, and he didn't exactly invent the idea of going to the beach.

krschultz··on Firms envision ways for New York to absorb 9M residents
I have, it's a nice venue, but there are lots of places to see a concert.

I care a lot more about bulldozing the South Bronx.

krschultz··on Firms envision ways for New York to absorb 9M residents
Changing zoning, building codes, and property taxes to encourage more growth but not dictating top down development.
krschultz··on Firms envision ways for New York to absorb 9M residents
I haven't seen a lot of arguments that the things he built were a positive in the end.
krschultz··on Firms envision ways for New York to absorb 9M residents
No matter what you think will happen with global warming, there is a 0% chance we're going to let NYC go underwater.
krschultz··on Firms envision ways for New York to absorb 9M residents
Even closer than that, aside from Jersey City and Hoboken nothing on the west side of the Hudson has a direct rail connection. Extending the 7 line to Weehawken would help.

I live in NYC. I'm not sure why you are being downvoted, rising oceans are a big concern.

That said I think the solution will be pretty simple. When we have to, humans are really good at moving dirt. We do it less often now because of the impact on the environment, but if there was a will then it's solveable. I would expect to see a dike ringing Manhattan in my lifetime. The city is currently encircling Manhattan with a "greenway" which is basically a strip of bike lanes & walking paths. Imagine that, but raised 20 feet.

I think the same treatment will be useful for Brooklyn & Queens. I would close off some of the rivers that go into the boroughs (e.g. the Gowanus) to make the area that needs to be closed off smaller. That will be a bit disruptive to some industrial sites, but nothing crazy.

All of this works because each square mile of NYC is worth so much money and has been built up. I'd worry a lot more about suburban coastal areas where the density doesn't rally support building protection on that level. The urban areas will justify it, but if you live on the beach in NJ or LI, rising sea levels will be a major problem.

krschultz··on The Cancelled Comma One Would Have Embarrassed the Car Industry
Only this would be worse. Someone can choose to buy Soylent or use Theranos for themselves and no one else gets hurt. If you a person buys a crappy self driving car system it could kill me, a totally unrelated person.

I don't care how much of a libertarian you are, that's exactly the reason why we have regulations.

krschultz··on Buttery Smooth Emacs
As someone that been on HN for 9 years, pushing back on these kinds of comments is my business. This is my opinion on the value of you coming to Hacker News to complain about the author's writing style, and secondarily aimed at other commenters here. Your style of just summarily shitting on how the author wrote this piece adds no value to the discussion. Clearly lots of other people like it, this has been the #1 piece on HN for hours. If you don't like it, no one is forcing you to read it or asking for your opinion.

In the mean time comments like yours dissuade other people from putting themselves out there. I'll get 100 positive responses on something I write or say at a conference, but the 1 hater always sticks out more. If that means fewer people write publicly it makes us all worse off.

krschultz··on Buttery Smooth Emacs
Then don't read it. Surely there will be a summary blog post written for those that don't like long form. I personally enjoy the meandering sometimes. It's the difference between reading a book and reading the cliff notes, they each have their place.
krschultz··on Do the math: too much calculus? (2012)
That's a good point. I'm not an educator and it's been a while so I can't recall the sequence of stats 101, calc 1, more stats, more calc, etc. It all blurs together at some point.
krschultz··on Do the math: too much calculus? (2012)
I graduated with a mechanical engineering degree, meaning I took 3 semesters worth of Calc and 3 more semesters worth of differential equations. So I'm not one to hate on math or calculus specifically. But I think high schools should focus more on statistics.

Statistics is relevant to more fields than calc. It matters a lot more in business and in all the jobs where you use calc you will also have to use statistics. It's also useful for citizens to understand statistics better - and educating citizens is truly one of the purposes of public education.

That wasn't the argument.
krschultz··on Why Your Excellent Conference Talk Was Rejected
Had you presented to the meetup before applying or only after you knew that you were accepted in the conference? Even having done a talk once is far better than most applications.
krschultz··on Why Your Excellent Conference Talk Was Rejected
I think of it as a ladder that you progress through as a speaker. This reduces risk for the organizers, but it's also good for your growth as a speaker. If you think you can just hop right into a conference talk with no warmup, then the earlier steps should be a breeze.

- Short meetup talk (10-20 minutes).

- Long meetup talk (20-40 minutes)

- Conference talk.

The only gotcha is that most meetups are not recorded. That makes it difficult to apply for conferences outside of your hometown.

krschultz··on It’s Been Real, Android: Why I’m Retiring from Android
Buck's speed improvement is heavily dependent on breaking your code into modules. What was your project setup like?
krschultz··on It’s Been Real, Android: Why I’m Retiring from Android
I was an Android developer, then flipped to being an iOS & Android developer. I chose to go back to solely Android for similar reasons to the OP. It felt like it was impossible to be excellent on both platforms. I was struggling to keep up with the pace of change.

I ended up choosing Android because I found more demand for Android developers in the market. I certainly understand some of the OP's frustration with Android development.
