Pee on these San Francisco walls and they’ll shoot it straight back

When San Francisco’s public works director Mohammed Nuru talks about “hotspots,” the multitude of locations where you can connect to free Internet is the last thing on his mind. Instead, he’s referring to particular places where people like to pee. Public places, that is.

Nuru told SF Gate recently that he and his team are now taking steps to “discourage people from peeing at many of our hotspots,” though their methods may surprise some. Those who feel the need to empty their bladder on the city’s streets from this week may well watch in horror as their urine deflects off the wall and sprays straight back onto their pants and shoes.

City officials are so fed up with some people peeing in public – and the resulting stench – that they’ve decided to paint a number of walls with “super-hydrophobic” paint that repels the liquid, a property which has the effect of throwing the issue straight back in the perpetrator’s face, so to speak.

The pee-resistant paint, called Ultra-Ever Dry, is the creation of Ultra Tech, a Florida-based chemical cleanup and waste management company, SF Gate reports. Ten walls in areas where pee is particularly problematic have been coated in the special paint, with signs on each one reminding potential pee-ers that the wall is not a public restroom so they should “seek relief in an appropriate place.”

It doesn’t, however, warn them that should they ignore the notice, much of their pungent yellow liquid will be landing right back on themselves, meaning they’ll have to go about the rest of their day wondering why people are giving them a wide berth.

Indeed, this seems to be the main downside to the plan: that urine-repellant walls could end up making even more of the city smell, though officials are of course hoping publicity around its new initiative will help to highlight the issue and make people think twice about taking a leak outside. Commenting on the effort to clean up the city’s streets, Nuru said, “Nobody wants to smell urine,” adding that the pee-resistant paint plan is part of ongoing efforts to make the city “smell nice and look beautiful.”

AI turned Breaking Bad into an anime — and it’s terrifying
Split image of Breaking Bad anime characters.

These days, it seems like there's nothing AI programs can't do. Thanks to advancements in artificial intelligence, deepfakes have done digital "face-offs" with Hollywood celebrities in films and TV shows, VFX artists can de-age actors almost instantly, and ChatGPT has learned how to write big-budget screenplays in the blink of an eye. Pretty soon, AI will probably decide who wins at the Oscars.

Within the past year, AI has also been used to generate beautiful works of art in seconds, creating a viral new trend and causing a boon for fan artists everywhere. TikTok user @cyborgism recently broke the internet by posting a clip featuring many AI-generated pictures of Breaking Bad. The theme here is that the characters are depicted as anime characters straight out of the 1980s, and the result is concerning to say the least. Depending on your viewpoint, Breaking Bad AI (my unofficial name for it) shows how technology can either threaten the integrity of original works of art or nurture artistic expression.
What if AI created Breaking Bad as a 1980s anime?
Playing over Metro Boomin's rap remix of the famous "I am the one who knocks" monologue, the video features images of the cast that range from shockingly realistic to full-on exaggerated. The clip currently has over 65,000 likes on TikTok alone, and many other users have shared their thoughts on the art. One user wrote, "Regardless of the repercussions on the entertainment industry, I can't wait for AI to be advanced enough to animate the whole show like this."

4 simple pieces of tech that helped me run my first marathon

The fitness world is littered with opportunities to buy tech aimed at enhancing your physical performance. No matter your sport of choice or personal goals, there's a deep rabbit hole you can go down. It'll cost plenty of money, but the gains can be marginal -- and can honestly just be a distraction from what you should actually be focused on. Running is certainly susceptible to this.

A few months ago, I ran my first-ever marathon. It was an incredible accomplishment I had no idea I'd ever be able to reach, and it's now going to be the first of many I run in my lifetime. And despite my deep-rooted history in tech, and the endless opportunities for being baited into gearing myself up with every last product to help me get through the marathon, I went with a rather simple approach.

This bracelet helps you fall asleep faster and sleep longer

Have you been struggling to get the recommended seven hours of sleep? It's always frustrating when you get in bed at a reasonable time, then toss and turn for a hours before you actually sleep. The quality of that sleep is important too. If you're waking up multiple times during the night, you're likely not getting the quality REM cycle sleep that truly rejuvenates your body.
