const range = (end, start) => {
  // Return an Array of a sequence of integers from start to end-1.
  // Let end be an non-negative integer, which represent the last number in a sequence exclusively.
  // Let start be an (optional) integer (zero, negative or positive), which represents the first number in a sequence inclusively.
  // Examples:
  // range(4) produces [0, 1, 2, 3]
  // range(4, -3) produces [-3, -2, -1, 0, 1, 2, 3]
  if (end === undefined) return [];
  if (end < 0) return [];

FreeNAS

Troubleshooting

Mini SAS Male SFF-8087 to 4 Female SATA cables

I bought 2 cables for a FreeNAS array of 8 hard drives in 2019. I used them with an LSI HBA and a Rosewill case. I had trouble with the hard drive connections when I initially set them up. Occasionally a drive would go offline. I assumed that his was poor contact with the hot swap bays and re-seat the drives until they came online. Recently I discovered the issue: one of the SATA connections on the Mini SAS Male SFF-8087 to 4 Female SATA cables does not reliably connect. From my /var/log/messages I get these errors:

Devcontainer: Custom Shell

Does your fresh devcontainer terminal feels sluggish when you cd into a /workspaces repository? You are not alone. Turns out that what ever injects the command prompt (possibly the VS Code extension) uses slow code. Want to fix that? Replace it with something else.
