John Young, founder of Cryptome - an early model for WikiLeaks - has died. The Register has a good obituary. I had a run-in with John in 2010 after Cryptome got hacked and I wrote about it for Wired. He was often difficult to deal with but no one could doubt his dedication to the transparency cause

Quick reminder: when something is called "original" on Ali Express, it's still the same crap, just with a fake sticker and at double the price point.

#android office connector has a annoying calendar syncing bug: it decides what to sync not based on the event's date but on the creation date of said event. An appointment made more than 15 days ago for tomorrow has a very high probability of being lost in sync.

Travel Tip: never buy anything at an airport duty free shop. Heavily taxed items such as Tabacco is usually cheaper on the plane (!) itself. Everyday items are much much cheaper in supermarkets.

GPS spoofing and jamming - as experienced by commercial pilots www.youtube.com/watch?v=wm9B...

youtube.comGPS jamming (& spoofing) explainedIn this video we walk you through what GPS jamming and spoofing is, the difference between the two, and our new Flightradar24 GPS jamming map which shows you up to date info about where in the world GPS jamming is currently affecting aircraft. Then we let the pilots of our recent SAS flight from Copenhagen to Bangkok explain some of what they experience due to GPS jamming, and what they do to mitigate it. Take a look at the Flightradar24 GPS jamming map here: https://www.flightradar24.com/data/gps-jamming Don't miss the full SAS A350 flight deck video this was inspired by, here: https://www.youtube.com/watch?v=4dG_Whxzdkk Follow Flightradar24 on Instagram - http://instagram.com/flightradar24 Find us on Facebook - https://facebook.com/flightradar24 Twitter - https://twitter.com/flightradar24 LinkedIn - https://www.linkedin.com/company/2740521 ------------------------------------------- Useful flight tracking links: ✈️ Track live flights here - https://www.flightradar24.com 🎧 Listen to our podcast here - https://www.flightradar24.com/blog/avtalk-podcast 🛩️ Find out more about subscriptions here - https://www.flightradar24.com/premium 📕 Read our flight tracking glossary here - https://www.flightradar24.com/glossary 📧 Sign up to our Aviation newsletter - https://www.flightradar24.com/blog/on-the-radar-newsletter/ #flightradar24 #gps #navigation

Also only in Germany: Your PhD certificate is in German and English, but it is from Austria, so we need it recertified for €200,- and it will take around 3 months.

Adrian Dabrowski@atrox.at

Everywhere (faculty position): Once we are ready to employ you after the hearings and expert reports, we might need your doctoral diploma for verification. Germany: Please include your Ph.D., master's, and bachelor's diploma + transcripts and your A-level diploma in the application.

just in case you do not want to spend 14 days and at least 33 emails with ACM TAPS support to get your two papers published, because the system does not provide any error logs - here are some observations and lessons I had. #acmtaps

If your file does not compile, you need to write tapssupport - to either unblock/reset the submission system or look at your code. They will not do it on their own (tested for 6 days). Don't expect any error logs from them - begging doesn't help. They are super-close-lipped.

also the LaTeX parsers are slightly different. TAPS' table parser doesn't like \\%... . be sure to add a space in between: \\ %.... Also the last line of a file should end with a new line.

Many of the "allowed" packages are not the real packages - they are mostly Perl re-implementations (in LateXML). Some advanced functions and some hooking mechanisms will likely not work. Use the above pdf/html switch to provide different mechanisms.

need a paginated table for the PDF but a continuous one for the HTML version? you can distinguish between the two with a switch like this: \ifdefined\pdfobj pdf version \else xml/html5 version \fi

you might need to conditionally NOP some functions that aren't available in all environments, such as \Description, \balance and \ACMSubmissionID, like this: \ifdefined\Description\else\newcommand{\Description}[1]{}\fi

ACM's contractor uses a LaTeX->XML->HTML pipeline -- most likely LateXML on a Windows Server. Install your own copy to get some meaningful error messages.

Dear app developer: just because my system language is English, doesn't mean I wish you display times in masochistic 12-hour am/pm format (without any way to change that).

All #USB-PD trigger modules I see only allow the selection of a specific voltage but not of a required supported current for the power supply (via PD) and the cable (e-Marker).

#Academic publishers are like, "Good! You made it through peer review! You can now either give us an exclusive license so we can put it behind a paywall, or you can pay $1000 to make it open access. It would be a shame if no one could read your precious paper, wouldn't it?"

oh wow. The Baofeng GT-5R, is like, the last 10 years did not happen at all! Two-line crappy dot-matrix LCD, with a number pad, a cumbersome UI, and the old Kenwood TRS connector. Its a UV-5R clone, now, just with some filters on the TX side, to make it FCC complaint.

One hour of a Microsoft Teams call over LTE drains 55% battery and 835 MB on my Android, while on Zoom it's only 31% & 278 MB. Haven't they learned anything since their disastrous Lync client, years ago? Is the protocol not optimized for mobile, or is the client so poorly written?

On every single amazon.de page in Germany, there is a link at the bottom for canceling all kinds of Vodaphone subscriptions. I wonder how badly Vodaphone must have pissed off Amazon for them to include such a link?

In academia, you are never truly on sick leave. Reviews are still waiting to be written, exams still need to be graded, paper deadlines are still looming, and funding proposal deadlines are still approaching. #postdoclife

Another big data breach at a hotel chain... In reality, such breaches never had a significant negative impact on their business - even with us, privacy and security experts. Our conferences and workshops still happen at the very chains that lost our CC and passport data.

You are up to date.
