This is not a "feature", it's just a by-product of how iptables works. The alternative would be to have a proxy run in userspace, instead of letting the kernel forward packets

I still don't see how that's an issue, yes a password using a series of ridiculously complicated family emoji will be truncated but the actual bytes still provide entropy, just because the data doesn't use pixels when rendered doesn't mean it doesn't increase the search space

Does this really need yet another blog post? 72 characters is more than enough to be resistant to brute-force attacks, as demonstrated by thousands of data breaches containing bcrypt hashes that remain uncracked (excluding the obvious top 1k passwords/ credential stuffing). In my personal opinion calling it "unsafe" is just fear mongering, especially in conjunction with a recommendation of using Argon2 which is comparatively very new and is probably safe - but once again, does not have the proven record that bcrypt does.

Yeah you definitely should not be paying that much. Throw your NMI into https://www.energymadeeasy.gov.au/ and it'll show you the most cost effective option from your actual usage. I'm also in Sydney and pay 29c flat/ 18c secondary circuit

I personally always use

  picture {

  }

so that flexbox behaves in a way you would expect.

that's definitely a 3d model and the harbour bridge a few hundred metres away is still a flat line on the water

This is pretty cool, but demonstrates why google/apple maps make heavy use of bespoke models vs just the map data, as is demonstrated pretty well by the sydney opera house and harbour bridge

As an Australian it's always a bit of a shock to see brand new European and American trains stopping at platforms no taller than a kerb, meaning you have to walk up steps.

I'd be very interested to see how much of a bottleneck boarding from the lower level of these trains is, in sydney we have double deckers where you board from the middle level from high platforms[1] and the stairs are already a flow limitation in the city section, I can't imagine how bad it would be with people going up two flights of stairs
