Assuming the value of max passed in is "sane" (non-negative and within array bounds), it is strictly decreasing and should never overflow.
Re:Show HN: Coal – Containerized shell alias manager on Wednesday June 10, 2020 @12:36AM (#23473952)
Working on multiple projects at once with long build commands gets tedious quickly - I built coal to quickly containerize and manage your aliases.

Simple usage example:

$ coal new aws-lambda

$ coal add update "aws lambda update-function-code --function-name func --zip-file fileb:///tmp/main.zip"

$ coal add errors "aws logs filter-log-events --log-group-name /aws/lambda/func --filter-pattern \"ERROR\""

$ update

{ "FunctionName": "func", ... "LastUpdateStatus": "Successful" }

$ errors

{ "events": [ { "logStreamName": "<redacted>", ... "message": "ERROR...", }, ... }

$ coal new git

$ coal add update "git pull"

$ update

Already up to date.

$ coal load aws-lambda

$ update

{ "FunctionName": "func", ... "LastUpdateStatus": "Successful" }

For background, I'm currently a junior at a good CS school in the country, and I am interested in operating system and compiler development, as well as low level performance optimization. I'd really like to work in the R&amp;D sector at a top tech company (I've heard good things about Apple's and Nvidia's systems teams) in any of the fields above, but I'm having a hard time finding people who...

Re:Show HN: GDocsFS – A FUSE Filesystem Backed by Google Docs on Thursday January 09, 2020 @09:52AM (#22001637)
I recently learned about FUSE and thought it was so nifty that I had to try it out myself - this is the result. I'm still learning about Linux and filesystems, so this is a rudimentary version with basic functionality - any advice or feedback is appreciated!
