    We also released the 2nd half sky catalogue of the eROSITA X-ray survey at the same time, for 1.5 years of operations, in collaboration with SDSS. Here is a sky map and 3D plot wit…

    Starlink was also a UK astronomy software project from the 80s and 90s: https://en.wikipedia.org/wiki/Starlink_Project

    And when you meet them, if you're unlucky they don't want to hear your medical history and want you out of the door in two minutes.

    Isn't this the same thing with 32 GB already on a PCIe socket? https://www.ebay.com/itm/166850431555

    Personally, I think social media and academic publishing timescales, rewards and social conventions don't match very well. Social networking feels transient and impersonal. I would…

    A surprising number of scientists seem to use it, likely because of the now terrible atmosphere for scientists on Twitter/X and the emptiness of bluesky.

    What's the good of a perfect railway line if it never gets built? What happened to the capacity argument? There is likely a good optimum between the cheapest and most expensive pos…

    Isn't the problem that the requirements for line were "gold plated"? If they'd put in another standard rail line instead, it would have increased capacity, taken up much less space…

    I get proper IPV4 and IPV6 addresses with Easybell on VDSL. I've been with them a long time and they've been pretty good.

    Pedantically, it's Einstein Probe (EP), not Einstein. Confusingly, in Chinese it has another name, Tianguan, commemorating the observation of the supernova which created the Crab N…

    Stunt Island was pretty good. However, there are more unusual games out there with reasonable budgets, like Death Stranding, The Talos Principle, The Outer Wilds, Portal and X4:Fou…

    Of course it might be genuine, but there's also a history of r/LegalAdviceUK getting a number of creative writing exercises. See this post: https://old.reddit.com/r/LegalAdviceUK/c…

    Although adverts on the fridge are absolutely terrible, is this genuine? Here's a reddit post some time before that suggesting the scenario: https://old.reddit.com/r/assholedesign/…

    With google I can't find things I know exist. For example, it doesn't find several of my github repositories with unique names that have been there for years. With old google you c…

    Although Intel processors are efficient, modern AMD processors have much higher idle power usage, due to their chiplet design. They typically use at least 20W more power.

    It's certainly very useful. I do half my work using X11 over ssh and it works reasonably well over a LAN (at least using emacs, plotting, etc).

    You are plainly wrong. I know several astronomers who look at colour images to check that the software is working properly.

    Unfortunately the LibreOffice Impress is pretty bad. PowerPoint is what keeps me using Office. LibreOffice formatting looks bad on the screen (it resizes bitmaps to make the fuzzy)…

    That's not right. I'm an astronomer, and I often look at colour images and colleagues do, too. For example, the galaxies in a cluster of galaxies follow a relation of colours - bri…

    I believe many Atari ST models had their graphical OS (TOS/GEM) on ROM. The Archimedes with RISC OS felt revolutionary at the time, however. Several of the graphical desktop progra…
