• Posted Non-functional perl code testing - automated code review to Alexey Shrub

  I saw a very ugly Perl code, and I think that is possible because no code review exist in project. But always we have a very little time for human code review. I search CPAN modules for basic level code review by machine. I…

  I actually use WebDrive to do this, if anyone still happens to be looking for a reasonably-priced option. It is a bit less expensive than Expandrive (which I will admit I have never tried). But I've always had success with Webdrive and have been using it for years. www.webdrive.com

  For persistent connections I find it better to use the %C token in ControlPath. It produces a shorter string, so will help get around some path length restrictions. Also, that really ought not to be a path in a world-readable place like /tmp!

• Smylers commented on SSH Can Do That? Productivity Tips for Working with Remote Servers

  Both good ideas. %C didn't exist when I wrote the above.

  On a laptop only used by me, I was using /tmp/ (it avoids need to know your username to put in the config), but for shared computers it isn't a good idea.

  I was just thinking on this the other day. To answer your Hash question: Like another commenter said hash lookup time is constant. It's can be a better choice when you want to search the array multiple times.

  When I was thinking about this I did some benchmarks. Hopefully I've done them right. I tested arrays of 100 elements searching for an integer that was in the middle of the array. I've pasted the results below.

  The way I interpret it is that you'd need to do at least 7 lookups for a hash lookup to be a better choice than grep, and around 25 lookups before it outperforms…

  I forgot to mention that the reason why the lookup is slower on a single search in the first place is that I'm converting the array to a hash before doing the search. I'm using the "%hash = map { $_ => 1 } @array;" pattern you often see.
