"in the US, more than 10,000 journalists lost their jobs between 2022 and 2024 (...) Google, Facebook, YouTube, and TikTok have gobbled up the advertising dollars, and campy 30-second videos by influencers now deliver what passes for news on social media”

I once documented human displacement and desperation. Now, due to a crumbling media ecosystem, I am living it.

Google has known about a bug that breaks VPN apps for 7 months, leaving users exposed with no warning or error, just a VPN app that stopped working in the background.

If you're using ANY VPN on Android, you can help us by getting Google's attention to fix it.

We first reported this bug to Google in September 2025.

Others like @mullvadnet and Wireguard reported it even earlier, in August.

Google's response? "I don't see anything unusual."

Here's what's actually happening ⤵️

Lowering speed limits to 30 km/h can transform streets making them safer, calmer, and more livable. Yet these policies often spark debate. So what can cities learn from Bologna’s experience?

This Thursday, #OUVEMA is delighted to welcome Valentina Orioli for a lunchtime webinar at 12:00 (Swiss time), where she will share insights from Bologna.

@bert_hubert @jwcph as a former Microsoft customer facing engineer, I can back this up. Changing tools is incredibly painful for orgs, just in terms of training and Skilling. We held sessions that would last a whole week just for technical people on how to use new tools, and that process would always require follow up training and reinforcement for technical people. For non technical people this is even more pointed. Doing migrations to or from Teams, which no one loves, was and still is a laborious and slogging process, something that takes months or longer. Changing systems is hard, and without mandates and top level support, is extremely hard.

@jwcph I do a ton of talks on this subject. People are very attached to their working environment and even if they are unhappy with Teams or Word or Outlook, they also overwhelmingly don’t want change if they can stop it. Your single digit number is very much not what I observe.

It's International Women's Day, so when you see people zooming by on electric scooters, I remember Lady Norman and her autoped. She was a suffragist who insisted on being mobile without manly "protection" :) https://en.wikipedia.org/wiki/Priscilla_Norman

(UPDATE: Yes, many men in the replies. The autoped used a combustion engine, I know. My post is however NOT about the autoped, it's about the woman standing on it. I know, that's really hard for some of you to deal with. :)
