Open Infrastructure MapWe've just launched a revised design for the map! This adds more consistent symbology, and a few new symbols (including power portals), and better rendering of substation detail. This work was done with the help of @Catalogtree.
This is the first phase of the redesign - we'll be doing some more work on the UI of the map which will hopefully be ready soon.
Any feedback is welcome!
One of the two amateur radios on the International Space Station is busted. No SSTV (Slow Scan Television) opportunities for us earth-bound geeks in the near future.

"After 3 days of troubleshooting the ARISS ops team has determined SSTV Series 30 can not continue.
The ARISS radio in the Service Module used for SSTV is being taken out of service."
Do you (or your kid) like checking sports scores - but despise the garish, resource-hogging adverts, sensational headlines about everything besides the games themselves, talking heads, and not-very-subtle steering towards gambling, as present on mainstream sports websites?
https://plaintextsports.com/ is awesome. Thank you, so much, to its creator.

@todb - congrats! If you'd be content to bounce radio signals off the ionosphere for awhile, and communicate with operators in places like Mongolia, Bangladesh, and Tuvalu.. consider checking out FT8 and other "weak signal" modes. ~$65 worth of equipment can get you pretty far!
@todb - do it! Ham radio has been for me over the past couple years what infosec started out as, in my earlier years.. a super fun, geeky, knowledge-expanding hobby with a great community.
Another interesting vulnerability found in widespread (moving) infrastructure, using software-defined radio (this originally identified 13 years ago!) :

"Back when it was first implemented in the late 1980s, it was illegal for anyone else to use the frequencies allocated for this system. So, the system only used the BCH checksum for packet creation. Unfortunately, anyone with an SDR could mimic these packets, allowing them to send false signals to the EoT (End-of-Train) module and its corresponding Head-of-Train (HoT) partner. This would not have been an urgent issue if the EoT had only sent telemetry data. However, the HoT can also issue a brake command to the EoT through this system. Thus, anyone with the hardware (available for less than $500) and know-how can easily issue a brake command without the train driver’s knowledge, potentially compromising the safety of the transport operation."

"Relativity Space as a means to support the development of data centers in space. Such data centers, ideally, would be powered by solar panels and be able to radiate heat into the vacuum of space."
