5 talks to get up to speed on the JAMStack

Never heard of the JAMStack? Maybe not directly – but if you are doing web dev you have for sure heard of some of the players in this field, like Jekyll, Hugo, Jigsaw or GatsbyJS just to name a few. Indeed monoliths CMS like WordPress or Drupal (just to name these two but Wikipedia list easily a few dozen of major players across all stacks and companies) are often being criticised for being slow at scale or hard to customise and the overhead of growing beyond a certain point start to become ROI negative due to the heavy lifting you need to deploy to get the CMS to do what you want....

RTMP & Transcoding

Some research I have made recently while working on a broadcasting module of an app. Just saving here some of the best link I have found – as backup and maybe of interest for some people. Obviously if you are looking for a super structured article – I am far from it at this point – but that’s still the filtered version of a few hours of research to find the relevant and usable stuff – and it is practically what I have used to get to the point of a transcoding version of ffmpeg with facebook live (next step is to turn it into a nodejs microservice)...

A second round began one year later on January 4, 2013, and a third round following the confirmation of a fresh clue posted on Twitter on January 4, 2014.

One-to-Many An example of “one-to-many” might be parts for a product in a replacement parts ordering system. Each product may have up to several hundred replacement parts, but never more than a couple thousand or so....

Empathy is the new black

For what it’s worth, I have been noticing a raising interest for empathy in the past few years. It’s been popping everywhere from a variety of fields, either in business and entrepreneurship, human resources and management to more more remote fields like design and product development as well as the obvious therapy and education fields. Science seems to have discovered a couple of years ago that we are wired for it: but science isn’t really everything there is to it – I mean look at this article about this lady being a lead researcher on empathy, and she still managed to bullied colleagues and staff....

Douglas Adams 3 rules of innovation

Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works. Anything that’s invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it. Anything invented after you’re thirty-five is against the natural order of things.
