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

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 | 3 years ago | 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...

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 | 4 years ago | 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 | 6 years ago | 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 | 6 years ago | 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 | 6 years ago | 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 | 6 years ago | 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 | 6 years ago | 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??
