2015.06.04 in #202Loopify Recursions
Helmut shows us how he eliminated recursion in his LCS module, to avoid the warning about too-deep recursion.
2015.06.10 in #203Tuning Algorithm::Diff
Premature optimization is the root of all evil. But sometimes the need for speed is legitimate. Helmut needed Algorithm::Diff to be fast and put his nose to the grindstone. Fairly impressive sparks ensues.
2015.06.10 in #203Porting some modules to Perl6
To practice his hand at Perl6, Helmut ported two of his CPAN modules, Net::Similarity and Bag::Similarity to Perl6.
2016.02.14 in #238Credit the first or last uploader on meta::cpan?
This was Helmut's response to Rik's post. He thinks that everyone with upload permissions should be displayed, which is slightly different from my proposal.
2022.03.29 in #558First impression of "use standard"
An introduction to the "standard" pragma, which enforces Standard Perl syntax with Guacamole, with example code changes that may be required.
2022.05.02 in #563Tuning Levenshtein Distance
One of the first programming success of my son was reducing a process that ran 24-hours to 5 minutes. Partially by replacing a slow Levenshtein Distance calculator by a fast one. It was in Python. So I am glad to a similar comparison in Perl.
