This touched a nostalgic nerve. I never knew the life paths of Clive Sinclair and Gary Kildall were so similar.

@LaF0rge @kDelta @stman @Sempf espechally in places like #Germany where regulators like @BNetzA get record-breaking bids for #spectrum allocations solidly into the billions!

@LaF0rge @stman @kDelta @Sempf obviously that's why it was discontinued for a time in #Germany, as it was considered as obsolete as #HSCSD is in light of faster standards that - even without guaranteed bandwith - will yield higher throughput.

  • Obviously #CellBroadcast will necessitate a constant bandwith allocation for functionality as it's design is based upon repeating a message until it's transmissiom being removed.

Still, even in contended #spectrum this is manageable, espechally since most #MNOs only maintain vestigal #2G or #3G infrastructure solely for #emergency coverage and reliability, as most phones will call emergency services over 2G and 3G and not via #VoLTE.

  • To add insult to injury, most BSCs will downgrade to 2G-only service by default in case of power loss to maximize UPS range and in the case of #NewZealand even switch off all services but #SMS & #EmergencyServicesCalling to enshure people in need can get their calls out, as the population is instructed to use SMS for person-to-person communication (as SMS is a low-priority, non-realtime service using excess bandwith and thus not compete with calling like #EDGE and #CSD would.
Infosec.SpaceKevin Karhan :verified: (@kkarhan@infosec.space)@stman@mastodon.social well, there were *some commercial services* that used #CellBroadcast but for the most part it's *best feature* is the effective mass alerting of people in an area without needing them to *install yet another app* or *signup to yet another service*... - The [temporary] shutdown of #CellBroadcast caused hundreds of avoidable deaths [in Germany alone.](https://en.wikipedia.org/wiki/2021_European_floods#Germany) @kDelta@mastodon.ie @Sempf@infosec.exchange @LaF0rge@chaos.social @nitrokey@nitrokey.com @signalapp@mastodon.world @GrapheneOS@grapheneos.social

Just for fun another little throwaway app that has helped me to find some problems with the menu system (they're not always observing the z-order, as you can see in the screenshot).

So far it seems that you can actually build a working app using this, save for minor details. OS host integration is almost working too. All in all a great experiment to wrap another Deluxe Draw work day!

Did you know? Back in the 80ties Poland's #Elwro created quite good #ZX #Spectrum compatible Junior 800. With education in mind, they added networking! Now - thanks to Przemysław's hard work - you can build an exact replica with this open source project: github.com/codepainters/e800j

Down to original bodge wires with proposed mods and interactive BOM - this is a full blown education project on early computing and soldering. Need to flash a 2764 EEPROM? Can't find Intel DMA chip? Ask - small yet agile group of Elwro Junior 800 will help you!

A star with a weird color - Nova Lupi 2025 (V462 Lupi)

1st photo is not annotated. Can you find the nova?

2nd photo is annotated.

3rd photo was deliberately mis-focused so that stars were larger disks instead of small points. This makes it easier to see the color.

Note that there are plenty of orange stars and plenty of blue stars...but the nova has a unique color. To my eye it's a pale purple.

Why does the nova have a weird color?

4th image was taken from facebook.com/photo/?fbid=17712 it's a spectrum of the nova. Most stars have a blackbody radiation distribution, but novae (that's the Latin form, plural) have strong emission lines at discrete colors. That can make a weird color compared to most stars.

Image taken with a camera on a fixed tripod.
