Little known fact! Most email services are hosted in the cloud.

More precisely in The Oort cloud; which is about 40 light weeks or so away. That’s why unsubscribing takes so long. #tmyk

Windows 10 horrors:
"viewer" updates PDF

My Professor wife runs LaTeX in VirtualBox in Windows 10, using PDF "viewer" in Microsoft Edge (it does not lock PDF files, and redraws, so nice and sane etc). Trouble is, PDF files get a bit funky as a result; people who receive them complain that most viewers cannot view them.

Edge updates these poor PDFs on the fly, adding non-standard indexing after the final %%EOF, a XREF or whatever, broken (so editing out that in vim actually cures the file)

The SIGACT Committee for the Advancement of Theoretical Computer Science is planning a Wikipedia edit-a-thon, in Phoenix on June 24 as part of STOC: see thmatters.wordpress.com/2019/0

You can help, and you don't even have to brave the desert heat to do so! There's a shared spreadsheet linked from thmatters.wordpress.com/2017/0 where CATCS is crowdsourcing TCS topics on Wikipedia that need help. Add your favorite missing algorithm, theorem, complexity class, etc, and it's likely it'll get some attention.

Known as Internet Maintenance Day in China, June the 4th - the anniversary of the Tiananmen Square Massacre - is when censorship of websites is at its highest.

Bonus tip: keyboard shortcuts.

The '?' will give a list of these, and there's a whole bunch, allowing stream navigation, replies, author mentions, fave/boos, CW toggle, search, DM, lists of faved/pinned toots, user management, and more. If you've got a keyboard on your device, make use of it!

2nd Bonus tip: Tootstream, a CLI Mastodon client.

I'm making use of this on an older Linux box which grumbles loudly if forced to run a modern browser. Useful and a different (more focused) vibe.

"I’d love for data to be seen as a liability - something audited and discarded often to minimise risk. I also think it’d be great if companies had to notify you every time they transferred data to a third party, whether that’s uploading an audience to Facebook, or selling your pizza delivery address to Experian. I think off the back of that, the sudden public realisation at the scale of data transfers and selling would be enough to make change."

Chip-firing games and sesquinary notation: mathenchant.wordpress.com/2017

Jim Propp writes a monthly long-form math blog and somehow I hadn't encountered it before. This is one of its many interesting entries. One of the oddities about base 3/2 is that you calculate it bottom-up (by starting from a ones digit that's too big and then carrying things higher) instead of top-down (by greedily subtracting powers).

thank you (not) , for shipping in macos 10.14 the pcre library that does not support UTF strings. Very innovative for 2019...

This piece is brilliant, it's absolutely about Mastodon even if it doesn't mention it by name. It also speaks to why recent attempts to archive portions of the fediverse are ultimately very misguided and harmful.

gmail rejects some random subset of email from servers that don't have IPv6 reverse dns set..

so if your hosting provider happens to enable ipv6 autoconfig one happy day, everything breaks with no warning

GPUs are amazing. I generated these images at a full resolution of 12,288 x 24,576, each one taking a couple of minutes. My old python code would have taken most of a month to generate each of these!

Line arrangements in architecture: the beams of Cambridge's Mathematical Bridge (en.wikipedia.org/wiki/Mathemat) form tangent lines to its arch and then extend through and support its trusswork, while another set of radial lines tie the structure together.

The bridge just looks like a wood truss bridge in real life but this artificially-colored image, from commons.wikimedia.org/wiki/Fil, makes the underlying structure clearer.
