  • It’s pretty common to own a domain but not actually host the email server; doing on-premises email is a security PITA and most providers simply blacklist large swathes of residential and leasable (e.g. VPS) IPs.

    Unfortunately, if you get someone else to host your email, they often charge by the account, not by the domain. Setting up a new mailbox is therefore irritatingly expensive.

    A catch-all email works well, though, and is free from most of the hosting providers. Downside is you get spam…

    Jane@JaneDoe certainly seems more common than mail@JaneDoe.



  • Indeed, the US has a major lack of fixed-line competition and lack of regulation. Starlink doesn’t really help with that, at least in urban areas.

    I’m not familiar with the wireless situation. You’re saying that there are significant coverage discrepancies to the point where many if not most consumers are choosing a carrier based on coverage, not pricing/plans? There’s always areas with unequal coverage but I didn’t think they were that common.

    Here in NZ, the state funding for very rural 4G broadband (Rural Broadband Initiative 2 / RBI-2) went to the Rural Connectivity Group, setting up sites used and owned equally by all three providers, to reduce costs where capacity isn’t the constraint.


  • Starlink plugs the rural coverage gaps, but in urban areas it’s still more expensive than either conventional fixed-line connections or wireless (4G/5G) broadband. Even in rural areas, while it’s the best option, it’s rarely the cheapest, at least in the NZ market I’m familiar with.

    It also doesn’t have the bandwidth per square kilometre/mile to serve urban areas well, and it’s probably never going to work in apartment buildings.

    This is a funding/subsidisation issue, not so much a technical one. I imagine Starlink connections are eligible for the current subsidy, but in most cases it’s probably going to conventional DSL/cable/fibre/4G connections.

    Has it occurred to you that sometimes there’s actual evidence backing up the things you ridicule?

    You can go measure the acidity of rain in your back yard if you want.

    The sunlight in NZ is far, far harsher than if you go a few thousand kilometres towards the equator, where it should be hotter. We have some of the world’s highest rates of skin cancer. Are you implying that crisis actors are faking having skin cancer?


  • Aggregate bandwidth now rivals or slightly exceeds gigabit wired connections.

    Where that aggregate bandwidth is shared amongst large numbers of users, bandwidth per user can suffer dramatically.

    Low density areas may be fine, but cube farms are an issue especially when staff are doing data intensive or latency sensitive tasks.

    If you’re giving employees docking stations for their laptops, running ethernet to those docking stations is a no-brainer.

    Moving most of the traffic to wired connections frees up spectrum/bandwidth for situations that do need to be wireless.










  • Hmm. They’re very common in NZ now, however it appears that document is talking about modulating the actual normal shop lighting, not just an independent transmitter.

    I redid the electrical in a supermarket already fitted out with Pricer gear, and we went from dumb electronic-ballasted fluoros to dumb-driver LEDs, no DALI and certainly no comms uplink or modulation smart enough for that. I’m aware that the document suggests power-line communication to the drivers, but these were off the shelf dumb drivers/ballasts.

    The ceiling mounted Pricer transceivers would have been doing all the transmitting, and as I never saw any visible light coming out of them, and the HF ripple and instability from the shop lighting would have been significant, I think it’s pretty safe to say they were using some form of IR.
