# HackerRank - Cutting Metal Surplus
#
# The owner of a metal rod factory has a surplus of rods of arbitrary lengths. A local contractor offers to buy any of the factory's 
# surplus as long as all the rods have the same exact integer length, referred to as saleLength. The factory owner can increase the 
# number of sellable rods by cutting each rod zero or more times, but each cut has a cost denoted by costPerCut. After all cuts have 
# been made, any leftover rods having a length other than saleLength must be discarded for no profit. The factory owner's total profit 
# for the sale is calculated as:
#
#      totalProfit = totalUniformRods × saleLength × salePrice − totalCuts × costPerCut

;; Caveat: I'm an Elisp noob. I expect this will break if invoked before flycheck mode is possible, and am not sure that's possible.

;; Invoke flycheck preferentially when flycheck-mode is enabled.
;; My own workaround for https://github.com/commercialhaskell/intero/issues/268.

(defun flycheck-or-norm-next-error (&optional n reset)
  (interactive "P")
  (if flycheck-mode
      (flycheck-next-error n reset)
    (next-error n reset)))

Writing tech articles

This is a description of how I write tech articles for various blogs. Hopefully someone else will find this useful as well.

Create a Gist for the article

When I begin writing a new article, I create a new [GitHub Gist][gist] for the article files. The Gist contains a file for the article text and code examples related to the article.
