jeu, 04/30/2020 - 09:02

For science fiction fans, it feels like video chat was a long time coming, but now it's safe to say that a video call is indeed a great way to communicate remotely. Just as advertised by Star Trek and countless Philip K. Dick novels, the human face conveys a lot of information that the human voice doesn't. There's a human connection established through a video call that doesn't quite happen with text or even voice chats. It's a triumph of modern technology.

The life-changing magic of git rebase -i

mer, 04/29/2020 - 09:01

Software development is messy. So many wrong turns, typos to fix, quick hacks and kludges to correct later, off-by-one errors you find late in the process. With version control, you have a pristine record of every wrong turn and correction made during the process of creating the "perfect" final product—a patch ready to submit upstream. Like the outtakes from movies, they are a little embarrassing and sometimes amusing.

"Growing up, I was a bit of a field marshal," Megan Byrd-Sanicki, 2020 Women in Open Source Community Award winner, says with a smile. "I was always the one pulling classmates together. 'We're going to play a game. Come on, everyone, I'll teach you the rules.' I'd also have an eye to the sidelines, trying to identify who wasn't being included and how I could draw them in."

Computers are both my hobby and my profession. I have about 10 of them scattered around my apartment, all running Linux (including my Macs).

Comparing subscription, pay-per-bug, and consulting software business models

lun, 04/27/2020 - 09:01

At FOSS Backstage this year, I hosted a discussion on open source models and shared why I think subscriptions are a great way to support open source products.

Picking a business model

The company I co-founded, Nextcloud, only offers its services to customers on a (per user) subscription model. Some customers ask us during the sales conversation why they cannot just get access to our engineers on an hourly basis as they get from third party consultants: pay for the bug fix or support case, and be done?
