Calling it now: this $250 million, 3 year “flex lane” will not solve traffic congestion on I-84

Keep in mind that while DOT is doing this (and even more work on 84!!!), the $5.7 million in funding for the Naugatuck Greenway is apparently not in their budget

www.nhregister.com/connecticut/...

Construction of new 'Flex Lane' on I-84 in Danbury – the first in CT – to start in 2028

DOT spokesman Josh Morgan said the Flex Lane and other roadway upgrades in the corridor will cost roughly $250 million.

Look what arrived today 😃

I was incredibly lucky and won these two signed copies from @simkern.bsky.social

Would anyone be interested in reading along with me? I was thinking of a very flexible, read at your own pace, and discuss in a Discord as and when able read-a-long.

Two books by Sim Kern - Genocide Bad, which has an orange cover with blue line illustrations of missiles on it, and The Free People's Village, which has a red/orange cover with a black and while illustration of a person striking a machine with a baseball bat.

Brilliant. Haven't seen these before. A solar-powered, e-ink bus sked that refreshes every 30 seconds with the latest bus wait times, at a bus stop. So simple, effective, cheap.

$Across the top of the image is a fractured black rectangle where the left half is labeled "Frame: F is happening!" and the right side is labeled "Negation: F is not true!" left side of the box: "AI*" is so useful, it's revolutionizing everything. *massive, generative commercial "AI" models. right side of the box: "AI" capabilities are overblown, it's mostly slop. Below the box is a large image of Kirby, a pink blob inhaling and the "Frame F" fragment. In a box next to Kirby is the text: Kirby. K is happening. That's why they're saying F. In the pink box is the text: "AI" is functioning to fuel mass surveillance, exploitation of workers & the environment, and the consolidation of wealth and power on a massive scale.$

Imagine if we treated any other form of safety like this:"We should only install outlet covers in day care centers on a case-by-case basis, such as where a toddler has stuck his fingers in an electrical socket."

So instead of supporting universal daylighting, Brewer is now saying that the city should instead restrict parking at corners on a case-by-case basis, such as where there's been a crash or a fatality, a position that mimics that of the DOT.

Why Halloween candy shows up so early in stores has never felt like a mystery to me. What does feel mysterious is why, on October 20-something when I go to buy some for the neighborhood kids, the stores have already replaced their candy displays with seasonal decorations for December.

Tom Flood @tomflood.bsky.social · 17d

It’s September 21 and we’ve already eaten through two boxes of Halloween candy.
Our family is the answer to: why does Halloween stuff come out so early in the stores?

So lemme see if I understand today’s discourse.

Would be cool if the "urbanism/bike lanes/efforts to reduce car dependency are ableist" people would listen to disabled people who can't or don't drive occasionally. There's quite a lot of us.

A good reminder that we used to refer to chatgpt as a "deep fake text generator" judged too dangerous to make public by OpenAI just 6 years ago

Iris van Rooij 💭 @irisvanrooij.bsky.social · 12d

There is absolutely no good faith reason to use the term “AI” for any technology one is selling.

It serves only for dazzling people into thinking the technology has capabilities that it doesn’t.

If one wants a technology to be trustworthy, just use a transparent, informative term without hype.

Hi. It's me. 2 weeks later. This is done. 58 frames over 3 seconds, *50* layers in the final image. WOO. This was a long edit, felt like ACTUAL work so unless I get it again with the actual sunset I doubt I'll be editing more like this. Psyched for the final piece tho! 🪶

Comment period ends on Monday for a proposed rule change that would terminate student visas after 4 years. It also puts limits on exchange visitors and reps of foreign media, and shortens the length of time at the end of the visa from 60 days to 30 days.

Nothing makes America’s descent into energy irrelevance and denial of the future more evident than the approach to Amsterdam’s Schiphol Airport and seeing the sea dotted with countless wind turbines.
