Your questions about food and climate change

I’m convinced we need to do our part in fighting climate change and restore a more healthy environment. It’s definitely too late but everybody should contribute. The New York Times has a great overview on food impact on CO₂ emissions.

Does what I eat have an effect on climate change?

The world’s food system is responsible for about one-quarter of the planet-warming greenhouse gases that humans generate each year. That includes raising and harvesting all the plants, animals and animal products we eat — beef, chicken, fish, milk, lentils, kale, corn and more — as well as processing, packaging and shipping food to markets all over the world. If you eat food, you’re part of this system.

Is there a simple food choice I can make that would reduce my climate footprint?

Consuming less red meat and dairy will typically have the biggest impact for most people in wealthy countries. That doesn’t necessarily mean going vegan. You might just eat less of the foods with the biggest climate footprints, like beef, lamb and cheese.

It also contains some counterintuitive wisdom

But many other types of cheese, such as Cheddar or mozzarella, can have a significantly bigger footprint than chicken or pork, since it typically takes about 10 pounds of milk to make one pound of cheese.

Wait — cheese might be worse than chicken?

It depends on the cheese. But broadly speaking, yes, if you decide to go vegetarian by, say, eating cheese instead of chicken, your carbon footprint might not fall as much as you expect.

And finally a common misconception:

In general, packaging makes up only about 5 percent of global food-related emissions. What you eat matters a lot more for climate change than the packaging it comes in.

ECG coming to Europe?

I’ll be surprised if we get it so soon.

“for non-US regions “the ECG app is available on Apple Watch Series 4 with watchOS 5.2, paired with iPhone 5s or later with iOS 12.2 or later”.

A life saving feature coming with a software update. This is the future.


Apple released watchOS 5.2 enabling ECG in many european countries 🎉

FaceTime here we go again

Apple fixes another FaceTime bug in iOS 12.2 as well as many other nasty security related bugs.

FaceTime Available for: iPhone 5s and later, iPad Air and later, and iPod touch 6th generation. Impact: A user’s video may not be paused in a FaceTime call if they exit the FaceTime app while the call is ringing.

Update as soon as possible, if you can.

Customize GitLab interface

I love GitLab, I use it daily @Dimension and I even have an omnibus instance on a NUC @home for my personal projects and scripts.

For instance our teams are adopting Kanban to optimize the process and we heavily rely on boards for issue management. One of the key principles of Kanban is called visualize and we would strongly like to customize cards background to immediately recognize different kind of issues between features, bugs and generic tasks.

Face ID

Apple in their Human Interface Guidelines asks developers to avoid using custom Face ID and Touch ID icons:

Don’t use custom icons to identify system authentication features. When people see icons that look like the system’s Touch ID (thumbprint) and Face ID icons, they think they’re supposed to authenticate. Custom variants of these icons create inconsistency and cause confusion, especially when colorized, displayed at a large size, and presented out of context—like as a button label or on an app’s Settings screen.

However they don’t provide such standard assets.

6 colors Wallpapers

I’m in love with the new six colors iOS 11 wallpapers so I’ve created the larger macOS versions.

They’re available with different background colors (black, white, green, yellow, orange, red, purple and blue) and optimized for 2K, 4K, 5K and 8K resolutions.

You can download them from the link below the two examples.
