I love posts like this because it always has the subtle insinuation that weight gain is some moral failing on individuals instead of the natural result of allowing food producers across the board to sell the most unhealthy slop you could ever dream of while simultaneously making healthy food (literally just fresh, unprocessed items - i.e. the things that everyone ate for tens of thousands of years) a luxury item. This, of course, happening after food lobbyists successfully brainwashed entire generations of people with their shareholder-approved "food pyramid."
The reality is probably that kernel developers don't get any younger nowadays. And believe me, when you get older, have children and less free time, your waistline suffers a bit.
Or even a bit more than a bit.
The one advantage of being significantly ill this year is that I can finally fit into large shirts and medium pants after years of XXL and XL of the former and latter.
I'm xxl but I'm also built like a forklift. When I was younger I could throw rolls of vinyl flooring over my shoulder. I wish I took better care of my knees though.
Well I'm the only Linux nerd I know nor have I ever met another one in person and I'm a medium, could probably get away with a small if I had a touch more self confidence.
The shirt supplier may also be a factor. An American/EU size M is like an Asian L or XL. So if they changed the supplier then that's a possibility for the change.
Kernel developers are like black angels who were banned 🚫 for their incompetence so they had to find a niche that wouldn't remind them of corporate heaven. This is why they don't take care of themselves, they smell like tarmac, still send commits through fax and generally are stuck in the 90's. Maybe Japan would welcome them, but not 🚫 USA.
