The random rant of the week by mose.

Xenor release

This weekend Xenor, our dear Green Ruby editor, could not provide his links like he does every week. He was busy on another release. Please join me to congrat Xenor for his second kid that is in progress of being released at this very moment (update: at the time I finished the editorial job on the letter, the job was done, and all went well).

It may be a generational thing, I notice that a lot of geeks around me are reproducing this year. Maybe it's just a coincidence. But as a result the mindset of those new parents may evolve a bit. The priorities get to change a bit too. As far as I know, coder have been tricked for a while into working over hours just because they like what they do. Well, growing a family certainly changes the deal.

But those geeks I know that became new parents are in their thirties. Maybe that's how things are done nowadays, people get kids later in life than in previous generation? Or is it a factor localized to the technical population? Because the expectations of the work environment for a full no-life dedication, techies may delay their family building projects? I have to say I'm wondering.

Green Ruby News was a feed of fresh links of the week about ruby, javascript, webdev, devops, collected by mose, xenor and tysliu every sunday.
