I agree 72 characters is plenty for most circumstances. However, as the blog points out, this is a byte limit not a character limit.

Some of the family emoji can be > 20 bytes. Some of the profession emoji can be > 17 bytes. If people are using emoji in their passwords, we could quite quickly run out of bytes.

I think it’s a limitation worth being aware of, even if “unsafe” is perhaps overstating it.

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.

Meanwhile in Great Sydney Area, Australia right now, my current energy rate is 60c (peak) 45c (shoulder) 32c (off-peak) / kWh. That's totally fraud

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 {
    display: contents;
  }
so that flexbox behaves in a way you would expect.

It’ll take a little bit of time. But for example Cloudflare’s Warp VPN also uses Wireguard under the hood.

So while corp environments may take a long time to switch for various reasons, it will happen eventually. But for stuff like this corp IT tends to be a lagging adopter, 10-20 years behind the curve.

Warp actually uses MASQUE (UDP/IP over QUIC) by default

https://demo.f4map.com/#lat=-33.8564200&lon=151.2149210&zoom... f4map does a pretty good job, although I'm not sure if they use some extra model here or just render it based on osm data. Sydney opera house seems pretty well mapped and I think you could get something like that from it.

But definitely something similar can be rendered. Streets Gl handles complex shapes quite well: https://streets.gl/#52.23135,21.00506,45.00,0.00,1466.87

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
