In tech-fascism news: Omarchy - the Linux config files of racist DHH - now also partners with Elon Musk's SpaceXAI (Musk gives DHH 1.5 mio USD). The power grab (tante.cc/2026/09/11/power-grab) is in full swing. omarchy.org/news/2026/10/spacexai-j…

Power grab
Omarchy should not matter. But sadly it does. As a power grab. If you don’t know what Omarchy is here’s the short summary. David Heinemeier Hansson, creator of RubyOnRails, owner of a software business and millionaire, decided a few months ago to go all in on Linux and – because that’s just his MO – […]

no clue of this context but yes actually, this is true! ebikes allow people to expend similar amounts of energy to go significantly further. ebikes are a modifier on one's ability to travel by bike, allowing for significant or even full car replacement in many cases.
Transportation Research Interdisciplinary Perspectives
Volume 1, June 2019, 100017

Physical activity of electric bicycle users compared to conventional bicycle users and non-cyclists: Insights based on health and transport data from an online survey in seven European citiesPhysical activity levels, measured in Metabolic Equivalent Task minutes per week (MET min/wk), were similar among e-bikers and cyclists (4463 vs. 4085). E-bikers reported significantly longer trip distances for both e-bike (9.4 km) and bicycle trips (8.4 km) compared to cyclists for bicycle trips (4.8 km), as well as longer daily travel distances for e-bike than cyclists for bicycle (8.0 vs. 5.3 km per person, per day, respectively). Travel-related activities of e-bikers who switched from cycling decreased by around 200 MET min/wk., while those switching from private motorized vehicle and public transport gained around 550 and 800 MET min/wk. respectively.
Therefore, this data suggests that e-bike use leads to substantial increases in physical activity in e-bikers switching from private motorized vehicle and public transport, while net losses in physical activity in e-bikers switching from cycling were much less due to increases in overall travel distance.

px, cm, mm, in, pt, pc and Q, all anchored to 1in = 96px. Why absolute units stop being physical the moment they hit a screen, and where each one still earns its place.

If you want to avoid these Al generations of your Instagram posts, without switching your account to private, you'll have to dig into the app's settings.
Open the Instagram app, tap your profile, and then tap the three lines in the top-right corner of the screen. Then, scroll down to the Sharing and reuse tab. Here is where you should see a section labeled Allow people to use your content on Instagram and with Al features on Meta, with a toggle for Posts and one for Reels.
