suron What the interns have wrought, 2018 edition

I'd guess 5R is Five Rings Capital, not Rentech.

suron Climate change: A cooling consensus

The title sounds like it's saying that the consensus is cooling, not that there's a consensus that the planet is cooling.

suron A vim interface for gmail: Vmail

There's Conkeror, which uses JavaScript: http://conkeror.org/

suron Show HN: Interactive SICP

I think it expects you to combine the addition and multiplication, like this:

    (/ (+ 5 4 (- 2 (- 3 (+ 6 (/ 4 5))))) (* 3 (- 6 2) (- 2 7)))

suron Omniscient Debugging

The OCaml debugger also has time travel (http://caml.inria.fr/pub/docs/manual-ocaml-4.00/manual030.ht...).

suron Harvard investigates 125 students for cheating on final exam

It seems like the GP is saying that based partly on Harvard's reputation, not just the incident itself.

suron Everybody Hates Firefox Updates

https://support.mozilla.org/en-US/kb/profile-manager-create-...

It's just a command line argument.

suron Treating JavaScript like a 30 year old language

Functions are curried by default in Haskell.

suron Combining coins to reach a target sum (C, Python)

It's possible to do this using just a one-dimensional array. Since we only need the last column of the matrix we calculated to calculate the next column, the array can be updated in-place.

  coins = [1, 2, 5, 10, 20, 50, 100, 200]
  total = 200
  matrix = [0] * (total + 1)
  matrix[0] = 1
  
  for coin in coins:
      for j in range(coin, len(matrix)):
          matrix[j] += matrix[j - coin]

suron After 7.5 years, Firefox finally adds line numbers to view-source:

In Firefox, viewing the source from the error console highlights the line that the error was on.

suron Google Labs no more

He is using parentheses instead of square brackets, so the code is actually using a generator expression which will produce each value lazily.

suron Two examples of bad user experience caused by HTTP prefix being hidden in Chrome

So what happens if you select only part of the URL? What if you just want to select foo.com?

suron SVG-edit: Vector drawing in your browser

Apart from stability (which could also be considered a feature)

At what point does anything that makes an application more useful a feature? If this is the definition of a feature, then your second point seems a bit obvious.

suron SVG-edit: Vector drawing in your browser

Okay, this won't give me the latest bleeding edge version, but instead I get a mature application that is well-tested and provides more functionality than I ever needed. (in particular, more functionality than SVG-edit)

But the same goes for Google Docs and OpenOffice. Having more features isn't always what matters most.
