Huge inequality in emissions will,sooner or later, trigger public demand for climate justice. Worldwide,the richest 10% produce 50% of consumption-related CO2, while the poorest half produce only 10% of emissions.Wanna check where you stand?Check👉 wid.world/income-comparator/

Stepping into Shirokuro, the new Japanese omakase restaurant in New York City, you’d be forgiven for thinking you wandered into a sketchpad or a black-and-white storyboard.

Cool #transit paper alert! 📔🚨

"ProxiCycle: Passively Mapping Cyclist Safety Using Smart Handlebars for Near-Miss Detection"

«To address this issue [of route familiarity and associated risk/stress], we develop a novel handlebar attachment to passively monitor the proximity of passing cars…We deploy this sensor with 15 experienced cyclists in a 2 month longitudinal study…We then compare this signal to both historic collisions and perceived safety reported by experienced and inexperienced cyclists.»

Figure 4 from the paper "ProxiCycle: Passively Mapping Cyclist Safety Using Smart Handlebars for Near-Miss Detection" presented at CHI'25. The figure consists of 4 sub-figures showing the realization of a handlebar-mounted device for measuring vehicle proximity to a cyclist. The device is mechanically clever, mounted inside of the bar-end of a drop handlebar and stashing a 14500 LiPo battery there. The battery and assorted components are held together in a 3D printed housing and held down with a strap. The device consists of two VL53L8 time-of-flight sensor dev boards and 1 NRF52840 microprocessor board. One of the ToF sensors is mounted facing straight out ("side") and one is mounted facing behind the cyclist ("rear")

Mir platzt grad echt der Kragen. Achtung, Rant folgt.

NDR hat vor ein paar Tagen eine Reportage "Hamburg für Reiche" veröffentlicht.
Darin zu sehen ist ein Personal Shopper vom Alsterhaus, der einen seiner "besten Kunden" betreut. Soweit so gut.

Der Kunde ist Ron A. Callsen. Gründer und Geschäftsführer eines Pflegedienstes.

Never know what to make of guys complaining that women have cats and sex toys as options, my man if you’re getting outplayed by the combined forces of “runs on batteries” and “shits in a box” that’s a you problem, work on the you problem.

In Denmark, the second largest city, Aarhus, stops using Microsoft software to avoid dependency on American tech giants.

As Trump promised: “We will finally be respected again” and “There will be so much winning.”

Eine Tabelle, von oben nach unten: Geschwindigkeit, Wahrscheinlichkeit von Paketverlust, Zustellung.

Von links nach rechts:  TCP, UDP, dpd  (mit Logo)

TCP ist langsam, hat eine niedrige Chance auf Paketverlust und Zustellung ist garantiert.
UDP ist schnell, hat eine hohe Wahrscheinlichkeit von Paketverlust und Zustellung ist nicht garantiert.

dpd ist langsam, mit hoher Wahrscheinlichkeit für Paketverlust und ohne garantierte Zustellung

I absolutely want a stronger Canadian tech scene, but I absolutely do _not_ want sycophantic emulation of the Silicon Valley model whose economic and moral hollowness is now visible to everyone with the courage to see it. Short-term thinking, monopolization enabled by regulatory capture, enriching the few at the expense of the many: it has failed everyone except a handful of VCs and tech bros who will never admit their success has mostly been a matter of luck and privilege. 1/2

If you’re using this tech in your work, then step-by-step, as the US shifts more and more authoritarian, your work will be pulled with it and trying to continue to be equitable about equality, LGBT rights, and race will be an increasing struggle.

But because “less effort” is exactly what this tech is for, most will just let the US pull you into their automated bigotry.

I’m a big Neal Stephenson fan. He posted his remarks on AI from a recent conference. You should read the whole thing, but this was particularly concerning. It aligns with what I hear from the students I speak to. nealstephenson.substack.com/p/

There is an attitude in UX design and programming I truly hate. It's "we need to make all decisions for the user, because the user does not actually want to think[is a silly little consumer, actually]". It's the same attitude that gave us brain-numbing algorithmic Tiktok brainrot, surrender of all our digital sovereignty to big corps and general enshittification of computer-related things. And it drives me crazy to see it in action in FOSS (rant sponsored by reading vtrlx.ca/posts/2025/less-featu )
