• 2015.06.04 in #202 Loopify Recursions
  Helmut shows us how he eliminated recursion in his LCS module, to avoid the warning about too-deep recursion.
• 2015.06.10 in #203 Tuning 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 #203 Porting some modules to Perl6
  To practice his hand at Perl6, Helmut ported two of his CPAN modules, Net::Similarity and Bag::Similarity to Perl6.
• 2015.08.24 in #214 Elasticsearch with Mojo::UserAgent
  Helmut shows how you can talk to Elasticsearch via its JSON REST-API, using Mojo::UserAgent.
• 2015.08.25 in #214 Interface to Shopware with Perl
  Helmut gives some pointers on how to work with the Shopware API.
• 2016.02.14 in #238 Credit 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 #558 First 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 #563 Tuning 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.
