Great to see. They need to make Burwood Rd pedestrians and buses only. There's way way more people than cars, and the footpaths are made too narrow to squeeze in four lanes.

As much as I like the George St entrance to Wynyard, I've always thought could do with some signs or something to give it more of a sense of arrival.

Two beautiful women in yellow dresses stand in a field of sunflowers. Text: Using words from the bank, write a poem to impress the Yellow Dress Zealots. Hit Enter when you are done.
A duck, it is yellow, Its quack is its hello,
The sun favors goldenrod, As luck, Texas Hold'em god,
An egg, jolly yolker, A man's folly, poker,
Night's end, you'll be broker, Be you joke, or the joker.
This is the best I could do. I hope you guys love my poem.

(aside: when the chips are down you can wear a gold crown)

Ok so I have had time to properly read and digest Hogg's paper in detail and it will not shock you as his former postdoc that I agree with close to 100%.

But the spiciest take here isn't anything about LLMs, it's the assertion that astronomy lacks a right edge. This is true but you can't say it!

How's the mobile CPU landscape evolving? Thanks to process node improvements, a mid-range Android from 2025 is (finally!) as fast as 2017's iPhone 8, but a low-end (~$100) smartphone isn't yet as speedy as a decade-old iPhone 6s.

In software we can release MVPs and then continue to build the plane while it's flying, because nothing is real. It's not a goal, just a milestone where the thing is no longer useless.

It's not a concept that migrates well to things built from concrete and steel.

MOUNT VICTORIA, 127km from Central, is a beautiful station cut into sandstone, serving a town at the top of the Blue Mountains. It has two platforms accessed by a footbridge, but no lift. The station features a range of grand old buildings that show its former importance on the line. (1/4)

Rust in Android: move fast and fix things Posted by Jeff Vander Stoep, Android Last year, we wrote about why a memory safety strategy that focuses on vulnerability prevention in ...

β€œWe adopted #rustlang for its security and are seeing a 1000x reduction in memory safety vulnerability density ... with Rust changes having a 4x lower rollback rate and spending 25% less time in code review, the safer path is now also the faster one.”

What a shocker of a trackwork weekend, no trains thru the city except T4. How's that for planning!

City Circle closed. T2,T3 end at Strathfield. T8 ends at Sydenham or Central (map's wrong!)
T1,T9 closed Central-Wynyard.
Metro Closed.

Plus the new bridge at Sydenham is closed for some reason!

No, the pickle format is too intertwined with Python and Python code, you won’t be able to import it to R. The format encodes Python objects which you don’t have in R

Penny Wong is Australia's minister for foreign affairs. Having previously served as the nation’s first-ever minister for climate change and water, she applies an environmental lens to her international relations work, and is especially vocal about supporting climate-vulnerable Pacific Island nations such as Tuvalu. Wong helped implement the world's first "climate visa" program, the Falepili Union treaty, which allows Tuvaluans to move to Australia permanently to live, work, and study to escape the worst effects of climate change, while also guaranteeing Tuvalu’s continued statehood and sovereignty. This summer, more than a third of Tuvalu citizens entered the first ballot selection for the new visa.
