cmpolis··on California Will Stop Using Coal as a Power Source Next Month
Keep Diablo Canyon running!
cmpolis··on Project Scripts
Username checks out. Agreed, make is great and this seems like a reinvention (or rediscovering?) of it. Bazel is another good tool if something with more magic is needed
cmpolis··on Waymo shows off its futuristic “transportation as a service” vehicle
It would be great if we could end this arms race of bigger and bigger cars - they're less efficient, worse for pedestrians (bad sight lines and likeliness of injury if hit), take up more space and most of all - completely unnecessary in most cases!
cmpolis··on A coder’s guide to coffee (2002)
Moka Pot is the way imo - thick, rich tasting coffee that can be used like espresso (in a latte or Americano, etc...) made by a simple and easy to clean device.
cmpolis··on Ask HN: What are some cool but obscure data structures you know about?
this is a great way to store structured data in js since it saves the memory cost having repeated keys. e.g.:

  records = {
    time: [1000, 1001],
    price: [20, 25],
    volume: [50, 15]  
  }

  records = [
      { time: 1000, price: 20, volume: 50 },
      { time: 1001, price: 25, volume: 15 }
  ]
  // not a big difference with 2 records, but for xxxx records...
cmpolis··on The Learjet era ends with a final delivery
I think Learjet brand name has strong connotations with old tech and early days of private GA jets. Also, there is lots of competition at this size of a/c from newer/more modern designs (Pilatus PC-24, Embraer Phenom, Cessna Citation variants) and a very limited buyer pool
cmpolis··on Show HN: Should I Get a House? a better rent vs. buy calculator
Thanks for posting - this is really helpful (reminds me of this similar NYT tool: https://www.nytimes.com/interactive/2014/upshot/buy-rent-cal...)

A few notes:

- "Final Cumulative Profit" is a bit confusing since this is not necessarily profit - this is how much less of a cost a house is over an apartment?

- Is there a way to factor in opportunity cost of down payment being in the market instead of tied up in the house?

cmpolis··on How JavaScript Works: deep dive into call, apply, and bind
This sparked my memory of using "var self = this;" and "var _this = this;" Can't put my finger on it, but _this_ seems quite funny looking back on it (not to say it didn't work...)
cmpolis··on Apple becomes first U.S. company to reach a $2T market cap
have you looked at real estate prices, healthcare, education - inflation and money supply changes do not impact every asset at the same time and by the same amount
cmpolis··on Layoffs hit Quora
I used to be quite active on Quora, but have noticed a decline in content and ux quality - seems like they are trying to 'growth hack' in a way that is not benefiting users, e.g.:

- Links to other questions open in new tabs

- Most content is not shown unless you login, they are really trying to push being logged in and their mobile app

- Answers with images seem to be ranked higher (even if poor quality)

- Clickbait-y questions and answers

I hope they can return to quality since in the beginning it was such a great resource - it was awesome to be able to get answers from domain experts, celebrities, etc... and the site was very usable.

cmpolis··on Tesla races past $100B in market valuation
Why should it be valued on a revenue multiple similar to a tech company? Tesla has gross margins more similar to other auto manufacturers.

cmpolis··on For Her Head Cold, Insurer Coughed Up $25,865
The system is broken. I think a fundamental issue is that insurance is not really insurance - it is used to cover routine, expected things such as a flu shot (while increasing cost for these and adding complexity, bureaucracy, middlemen). E.g. car insurance does not cover oil changes and home insurance does not cover getting the gutters cleaned - they're there for major events.
cmpolis··on The Firefox UI Is Now Built with Web Components
This is one of the goals of Polymer- a cleaner API/abstraction layer on top of web components, right?
cmpolis··on U of Chicago projected to be the first U.S. university to cost $100k per year
This comment is sadly familiar to me - it sounds exactly how my friends in healthcare describe the state of their industry (more admin, fancy buildings, less focus or spending on patient care).
cmpolis··on Boeing's Crashes Expose Systemic Failings
The quote from Marc Moller seems counter to what I have seen as the prevailing thought regarding aviation accidents, which is: accidents are the result of a "chain" of failures; if any link in the chain does not occur the accident can be avoided. It is easy to say "software bug" or some single thing caused this failure, but there are many other factors that need to be considered: a/c certification requirements, training requirements (sim time, transitioning to new variants of an a/c), design philosophy for the Max, etc...

(Not an expert, but private pilot, have read many NTSB accident reports).

cmpolis··on Elizabeth Warren Came Up with a Plan to Break Up Big Tech
Right, telecom is a great example of where breaking up an entity benefited the consumer and prevented monopoly. /s (all the bells merged back in some form or another into present day AT&T and Verizon).
cmpolis··on Svelte is the most beautiful web framework I've seen
"People don't understand how the DOM works" x 1000. Many front end devs I have worked with are not aware that the DOM IS A TREE (and implications of this)!
cmpolis··on Svelte is the most beautiful web framework I've seen
I had a similar experience. I wish Ractive would have gained more traction; it was a good balance of "enough functionality that a web UI requires" and "simple enough to avoid cognitive overload and allowed for quick ramp up".
cmpolis··on Apple Moves Mac Pro Production to China
I wonder how significant the cost differences are for Apple with this move, especially since they mention previously manufacturing in the US and that many components are sourced in the US. How high will the margins be on these devices??
cmpolis··on Open-sourcing Sorbet: a fast, powerful type checker for Ruby
Thanks for bringing up Dart (underrated IMHO). The built-in optional typing helps with productivity and readability. There is also a great official style guide which goes over when static/inferred/dynamic typing are preferred: https://dart.dev/guides/language/effective-dart/design#types
cmpolis··on DuckDuckGo Proposes the “Do-Not-Track Act of 2019”
I don't want my ISP determining which content and infrastructure to funded; that seems like an even more broken model.
cmpolis··on California’s high-speed rail project was ‘captured’ by costly consultants
Quote is from Maya Angelou
cmpolis··on Put 1.7MB onto 1.44MB Floppies (1999)
Seems more usable than most "modern" websites. Content loads quickly, no modals or notifications that I need to click out of, important information is visually easy to find...
cmpolis··on Study Linking Autism to 'Male Brain' Retracted, Replaced
I think general programming best practices would apply, particularly code review and planning your code and breaking it up into discrete parts. I have seen many scripts for research that are 5k LOC of spaghetti that become impossible to read or adjust.
cmpolis··on “I’m moving out of state”: employees are trying to avoid California income tax
That's just the bill for state tax (need to consider federal, property, sales tax)
cmpolis··on Apple Lays Off 200 Employees from Autonomous Car Unit

  autonomous cars are so obvious and will eventually be so commodity
Apple's core business (smart phones) will be commoditized way before autonomous cars - we're already seeing smart phone improvements becoming more and more incremental, longer device lifetimes, people less willing to spend for the latest and greatest
cmpolis··on In Praise of Mediocrity
Having been both riders in this situation - I'd speculate that you're the one having more fun. I went through phases of recreational cyclist -> competitive cyclist and racer -> back to recreational cyclist.

Training and racing was immensely satisfying for the few moments when I would beat a personal best or place well, but it wasn't necessarily fun. The time, suffering and monetary cost of bike racing even on at the amateur-with-no-hope-of-going-pro level is crazy. The most fun I've had cycling was doing leisurely rides with friends or even just around the neighborhood with my partner.

cmpolis··on How well does population density predict U.S. voting outcomes?
What's up with the line of points at y=0.3772? seems anomalous
