Prof Logsdon* expects big changes under #Trump, Mr #Musk and Mr #Isaacman: scrapping programmes, closing NASA centres and more contracting out to #SpaceX, #BlueOrigin and other private sector firms. "There is a delicate balance between the interests of #NASA, #Congress and the #WhiteHouse."

Mr Isaacman has called the #SLS "outrageously expensive" and said that the major aerospace contractors are "incentivised to be economically #inefficient". bbc.com/news/articles/cn93797z

A #PSA for anyone living, staying, entering or even travelling to/from #Australia:

Apparently, #Australia decided to mandate it's #GSM systems to be shutdown because some #GalaxyBrainChair wanted to yeet #2G & #3G and demand everything to use #4G & #5G when in fact #VoLTE support is spotty at best and #EmergencyCalling oftentimes is explicitly hardcoded to not use #WIFIcalling or VoLTE as providing #triangulation and #LocationData via #SS7 is a desired feature when someone calls EMS, Fire Dept or the Police for help...

  • So essentially #tourists and anyone who hasn't an explicitly fully VoLTE-functional device they tested and verified to also do #EmergencyCalls via VoLTE are fecked with no reception when they need it the most!

  • This WILL KILL PEOPLE!!!

As much as we want to bitch about #GSM & #GPRS / #UMTS being #outdated and #inefficient, there are reasons to at least keep 2G available - ranging from lower power consumption to higher resilience in emergency situations.

  • #NewZealand for example does shutdown non-#EmergencyCalls during severe #Earthquakes so that people trapped and/or in need of urgent assistance can get through to dispatch operators and everyone else has to get in line and take a number aka. use #SMS or if existing #Internet to say "I'm fine!"...

  • If the Ozzies really need that juicy #UHF #SubGHz #Spectrum it's totally feasible to instead change the #allocations and reconfigure #CellularNetworks to use lesser bandwith for 2G (i.e. only keeping the absolute mininum of channels available for any service) and thus clear up space...

And to add insult to injury, Australia passed a #NorthKorea|n-alike #CellPhone #ImportBan for any device that doesn't do i.e. the bespoke proprietary garbage that i.e. #Telstra, #Vodafone and #Optus do with the #baseband modems of their #branded devices...

Seriously, which #TechIlliterate dickhead decided it's a good idea to do that #3Gshutdown in Australia without even a basic 2G network up and running at all?

@Elizafox yes, and with all the #Shitcoins and #Blockchain garbage I wounder if this is some kind if sick competition trying to create most #inefficient #computation done.

Because how else would anyone look at #Ethereum and #EVM and #NFTs and say: "Cool, I want that shite!"...

Like the only #Cryptocurrency that I can at least see the merit of is #Monero but solely because it's the closest to digital #cash and actually works for payments.

Sadly it's not fast enough for retail cashier use tho - I wished it was..

#Bitcoin is a digital commodity that derives almost all its current "value" from #fetishization and #speculative #mania. It's also a slow, #inefficient, and #wasteful payment network. The payment network is mostly only useful for pseudo-anonymity, #crime, or for avoiding censorship.

The composition of a Bitcoin network's payment record (blockchain) is ultimately determined by those who continually direct the most (otherwise pointless) computing power toward a new block of transactions seeking legitimacy. This is called "proof-of-work-based payment-validation consensus". A large #cabal of computer processing aggregation can, in theory, dishonestly manipulate the payment history of Bitcoin. Bitcoin enthusiasts argue that greed itself prevents such a cabal from hijacking the entire ecosystem, due to fear of completely destroying the Bitcoin price. The enthusiasts have so far been correct about this.

Tenth: Has the #retrofit gap changed?

Yes, for the worse!

Dont get me wrong: properties outside conservation areas are also very energy #inefficient. But, there has been some improvement.

The rate of improvement outside #ConservationAreas is faster than inside. And so, I document that the retrofit gap actually has *widened*.

Conservation area properties are falling behind.

Now, why does that happen?

Well, because the planning restrictions pose additional barriers.
