Issue #474 - 2020-08-24 - Perl and Docker

latest | archive | by Mohammad S. Anwar
Don't miss the next issue!

Hi there

To me, Docker, is a tool for DevOps. Having said that I have seen many fellow devs also played with it. At my work place also, we also have Docker-based QA environment. I must admit I have yet to get to the bottom of it. I remember last year, Dave Cross, did 4-part Into the Cloud Series. It was my first informal introduction to Docker. Talking about Docker, I would also like to share, a recent blog by Gabor Szabo, touching the Docker base.

Did you take part in the recent survey by TPF Marketing team? Well the survey is closed now and the result is out. Please check it out.

I couldn't resist myself from sharing the Team PWC achievement. Well Team PWC has completed 100+ contributions for 3 consecutive weeks for the first time. It is a big thing, if you ask me, as we only done this 2 consecutive weeks in the past. Why not join The Weekly Challenge, if you haven't done so already and have fun every week? It is very easy to join, just drop us a line at perlweeklychallenge@yahoo.com.

I would like to thank all the supporters on Patreon for the generosity. Gabor and I appreciate your support and encouragement.

Last but not the least, you please take care of yourself and your loved one. Enjoy rest of the newsletter.

Mohammad S. Anwar
