    Ah, cool. So, O2 replenishment is still required. Ta!

    I'm probably wrong, but AFAIK subs (navy war vessels) don't actually need much "new" or "introduced" oxygen when submerged.

    Us humans breathe out just as much oxygen as we breathe in - it's just that it's contaminated with carbon - CO2.

    I don't think that nuclear powered subs "generate" or "create" much oxygen for the purposes of life support.

    Instead, subs use CO2 "scrubbers" that are replaced at regular intervals. (See space flight, especially Apollo 13...)

    As stated, "diesel electric" subs ALSO need to either surface or "snorkel" when running on diesel to recharge their batteries.

  • Road tax for Australian EV users ‘sensible’, Tanya Plibersek says ahead of key economic summit

    Jump

  • @Zagorath

    "Road usage" has been taxed through the fuel excise paid at the bowser. This method is far from perfect, but it does allow reasonably anonymous travel.

    In the future, the gov't will have (at least) two ways of taxing the road usage of EVs.

    One way will be fair, equitable, based on 'mileage', and anonymous.

    The other way will permit the government to conduct 'real time' monitoring of every vehicle's speed and position.

    Our gov't will choose this second option, and with bipartisan support.

  • The AUKUS Submarine Deal is Dead - The US can’t provide the submarines. The UK can neither make up for the shortfall nor co-develop such a submarine in a reasonable timeframe

    The French wouldn't say that. They'd say whatever is French for "Sign here!"

    We'd then pay them a few more BILLION dollars, and the French would wait a week or two for another policy reversal.

    At the rate we're going, we'll end up buying our subs from China...

    AFAIK, every time Pauline Hanson goes swimming at a beach, an environmental impact statement needs to be completed, and clean up operations commence soon afterwards.

  • Should big tech be allowed to mine Australians’ text and data to train AI? The Productivity Commission is considering it

    Jump

  • @pulsewidth

    Yeah! I hear you, especially regarding 'onboarding' often being a barrier. (Thankfully, Signal is bloody easy.)

    My own attitude to family and friends is to say, "If ya wanna communicate with me, these are the acceptable options..."

    If they don't wish to use appropriate methods, that's fine, but they can't message me. Bugger 'em!

    I encourage the use of Signal as a 'gateway drug"... I mean, "app," and several people have subsequently added other private messaging apps as options.

  • @quokka

    I know I'm going to regret asking this, but why not Signal?

    Yes, I know it has the disadvantage of not being decentralised, and it's not anonymous as a phone number is required.

    However, for the vast majority of people, it is the simplest and easiest solution to gaining E2EE comms.

  • Australian Labor government threatens Signal encrypted messaging system

    Jump

  • @VanillaPuddinFudge

    Yes...... but that's OK.

    Lemme explain...

    A Signal user will commonly have the client app installed on their mobile device.

    They may also have a second client on a laptop that syncs the same data.

    If the user goes on holiday for a week but leaves their laptop behind, it won't be synced to the laptop.

    On return from holiday, the laptop client uses its decryption keys to retrieve the last week's worth of messages.

    I think Signal can do this (retrieve cached messages from the Signal servers) for up to 14 days.

    That said, the entire Signal cache is encrypted on their servers, and one's messages are fully E2EE and retrievable only by the user.

    (However, one weakness of Signal is that a desktop or laptop client's cache is stored unencrypted. To secure these, one needs to use full disk encryption at the OS level or higher.)

  • Signal boss warns app will exit Australia if forced to hand over users’ encrypted messages

    "Under FISA order, signal would provide logs."

    How would Signal do this? Logs of what?

    Corresponding parties? Messages? They don't have them.

    They'd have to rewrite their backend code to obtain them, and changes would also need to be made to the Signal client apps.

    It would not matter if the FISA Court ordered that logs be produced in secret by Signal. Any such logs could not be obtained without significant changes to the way Signal works. Users would know.

    Yes, Signal does have some shortcomings, but these are acceptable in most 'use cases' for most threat models.

    Signal is best used as a private, E2EE alternative to SMS. Only a fool would use it for the most sensitive of communications. (Like, you know, discussing an impending military strike...)

    We all know of the alternatives, including (but not limited to) SimpleX, Session, Briar, Element etc.

    Signal knows when a user wqs last connected, but not the IP address of that connection. The system has been specifically designed to minimise the meta data available for collection.
