Our next nominee to join the Perl Foundation board is a candidate to take over the very important role of President. We are very excited to present Stuart Mackintosh for this position. Stuart is based in the UK and has been working with Open Source software for over 25 years and through his company OpusVL since 1999.

Over that time, he has worked with several open source organizations including OFE, FSFE and other Open Source industry associations around the globe. Most recently Stuart leads OpenUK - a not-for-profit organization that advocates the use of open source in the UK and supports the development of the supply chain and customer base.

He is an avid advocate for Perl and has worked through his company to support Perl community initiatives. A more extensive bio is available on his website.

Below are Stuart's answers to the questions we ask of all board nominees:

  • Why do you want to become a member of the TPF Board?

I have been involved with Perl for 25 years, firstly as a developer, then building on Perl to develop an Open Source solution implementation business.

Additionally, I lead OpenUK the not-for-profit UK Open Source industry association and a couple of other business interests.

Perl has enabled a great deal to be achieved for my customers and many have gone on to be highly successful.

Perl has given a great deal but also has missed many opportunities. I am not one to throw stones but seek the part I can play in making things better. An invitation to join TPF means that I can return something back to the community and also see if I am able to help TPF take a bigger step forward.

  • What existing TPF initiative(s) are most important to you and why?

TPF provides a valuable role within the overall steering of Perl and the conferences are an essential part of the technical progression. Managing revenues and grants is important to developing the communities and having this function on neutral grounds supports integrity and sustainability of Perl as a whole.

Of greatest importance are the established Perl communities.

  • What goals would you like to see TPF pursue in the future?
  1. Pragmatic advocacy: Perl is excellent, and is a standard component of most digital things. I would like more people to know how and why they should also know this. The reasons that I selected Perl 25 years ago are as relevant today to the new generations of digital pioneers.

With my Perl team, an initiative was launched some years back however in isolation we were not able to gain traction and develop further. Although the site is outdated, the reasoning is not so I propose that we set goals for communications and awareness.

  1. Sponsors: An increase in breadth of sponsors is important to strengthen the TPF foundation and to do this, a value proposition is required.

  2. Student resources: Developing appropriate resources as 'on-ramps' to Perl for beginners and students would enable them to get more done as well as broaden the Perl communities.

Also important to me is the security profile of Perl, it's brand identity, and maintaining quality of everything we do under the Perl name.

Following our standard policy, we invite the community to comment or ask questions of Stuart for a period of two weeks.

The Perl Conference Pre-Conference Newsletter

In this issue:

This year's European Perl Conference takes place in Riga, Latvia, between the 7th and 9th August 2019. This is the 20th edition of the conference previously known as YAPC::Europe, then TPCiA and TPCiG, and now it is renamed to PerlCon. Despite the name and location, our attendees come from all around the world. The top five countries with the most attendees are the UK, Germany, USA, Russia and the Netherlands.

The main program includes three days of three tracks of talks, including the keynotes given by Larry Wall and Jonathan Worthington. Among the talks, we have a lot of both Perl 5 and Perl 6 related talks, as well as a number of topics which are not purely dedicated to Perl, such as working with databases, or creating virtual environments, etc. Until the 15th of June, it is still possible to submit a talk. The conference schedule will be published at the end of June. Explore the talks that are already submitted at

Beyond the main program, there is an extensive entertainment block, which includes two (two!) pre-conference meetings, a cocktail and beer parties at the end of the first day, the Game night, the Attendees dinner at the second day, and a River cruise at the end of the third day, thus you can join if you do not leave immediately after the conference is finished. The schedule will also include three sessions of lightning talks.

You can get your conference ticket on our website:
