I've a "old #astronomy software" side project and I'm looking for the early Mac software "StarMap" or "Star Map" from Bruce Webster.
So far my searches came up empty, but I'm not a specialist in old Mac software.
Does anyone have a copy of this app?
It's described in detail in a July 1985 BYTE article: #retrocomputing

Interesting and fulsome interview on exactly how NORAD reacted to the plane hijacking in Victoria/Vancouver on Tuesday. They speak to the commander of NORAD, currently a Canadian.
I appreciated the last section most though:
“It's the only bi-national command in the world; it's been a strong bi-national command since 1958, and nothing has changed.
We don't ever talk politics at work. It's not something that we do, nor does it affect what we do.
I would say that we are as tight, and probably tighter than we've ever been. As the world around us gets to be more dangerous, I would say that NORAD is even closer than it's ever been.
But one last thing — we have the watch. That's the slogan here for NORAD.
To give you a great example, all of the assessors, we all live on-base in homes that actually have a safe, we call it the SCIF. It's basically a classified room that has all of our systems. The days that you're on duty, you're either at work or in your house. Because the timelines are so small for answering the phone, you don't walk the dog; you don't do all these other things, and someone covers for you when you're going between work and home.
That's how important this mission is to us down here. It's really important for everybody in Canada to know that at NORAD, we have the watch”

Simulating time with square-root space.

Simulating Time With Square-Root Space
We show that for all functions $t(n) \geq n$, every multitape Turing machine running in time $t$ can be simulated in space only $O(\sqrt{t \log t})$. This is a substantial improvement over Hopcroft, Paul, and Valiant's simulation of time $t$ in $O(t/\log t)$ space from 50 years ago [FOCS 1975, JACM 1977]. Among other results, our simulation implies that bounded fan-in circuits of size $s$ can be evaluated on any input in only $\sqrt{s} \cdot poly(\log s)$ space, and that there are explicit prob…

Google unveils the $999 Pixel 10 Pro and $1,199 10 Pro XL, with 6.3" and 6.8" OLED displays, Tensor G5 chips, Zoned UFS storage, available on August 28 (Ben Schoon/9to5Google)

Pixel 10 Pro and Pro XL are all about upgrades you can’t see, still starting at $999 [Hands-on]
Google Pixel 10 Pro series doesn't have much in the way of visual updates, but it packs a lot of upgrades under the hood for the same price.

A previously unknown regular satellite of #Uranus has been detected in a series of images obtained by the Near-Infrared Camera (NIRCam) onboard the James Webb Space Telescope on 2025 Feb. 2: http://www.cbat.eps.harvard.edu/iau/cbet/005500/CBET005593.txt -> https://science.nasa.gov/blogs/webb/2025/08/19/new-moon-discovered-orbiting-uranus-using-nasas-webb-telescope/ - the object is located at a projected radial distance of 56250 /- 250 km from Uranus' center in the planet's equatorial plane, initial astrometry is consistent with the moon orbiting on a nearly circular orbit with an orbital period 0.402 days, and the observed IR flux from the object indicates a radius of 4 - 5 km, placing it well below the detection threshold of earlier images from Voyager and the Hubble Space Telescope.

Modern Minimal Perfect Hashing: A Survey
Given a set $S$ of $n$ keys, a perfect hash function for $S$ maps the keys in $S$ to the first $m \geq n$ integers without collisions. It may return an arbitrary result for any key not in $S$ and is called minimal if $m = n$. The most important parameters are its space consumption, construction time, and query time. Years of research now enable modern perfect hash functions to be extremely fast to query, very space-efficient, and scale to billions of keys. Different approaches give different tr…
