@callumjayhall @British_Airways This is airline industry standard, as frustrating as that can at times be.

@TrisH0x2A Goto as used in the 70's and 80's (think 10 PRINT "hello"; 20 GOTO 10). Used everywhere and for everything. Bad, awful, don't do it.

Goto as used in the Linux kernel, narrowly scoped, sparingly or for non-default control flow, fine, no problem, great idea.

@CyberRacheal Where is NDP ?

@yadavji_codes cd changes directory.

ci is an awful typo on a qwerty keyboard, but makes sense on a dvorak keyboard.

So ci is a typo made by a hipster developer.

All makes sense now.

[David Groves @pumplekin]

@CyberRacheal Because port numbers are properties of specific layer 4 protocols, most notably TCP and UDP, but also including others like SCTP.

ICMP doesn't have a layer4 protocol above it but it does have a query ID field though that "sorta" acts as a port number for some things like NAT.

[David Groves @pumplekin]

@CyberRacheal They just use IPv6 and avoid all this NAT nonsense that was supposed to be a workaround we used for a few years ...

... one can only dream.

[David Groves @pumplekin]

@CyberRacheal Common: You get it (or them) as part of a DHCPv4 lease.

Uncommon: You type it in somewhere.

Uncommon: You get it part of SLAAC+RDNSS, or as part of DHCPv6 (which may be stateless and not a lease).

Rare: Via DNR (RFC9463) or DDR (9462)

[David Groves @pumplekin]

@bootdotdev For me that time was a few months ago.

@litocoen Look at products like https://t.co/0s7IQiXCQB that actively do this. It changes consumer behaviour.

Instead of deciding if I want standard or first class train tickets, now I always book standard and have a punt at an upgrade, always at a lower price than advertised.

@CaptainInsightX I’d first ask how long it spikes for. Im thinking very different things if it’s 5 seconds vs 5 minutes.

[David Groves @pumplekin]

@AdamRamsay Personally I'm 100% fine with foreign born people being in our parliament(s).

What I'm not happy with is non-citizens, and especially non-citzens with visas that might mean they have to leave the couuntry in the middle of a term !

These can be two seperate things.

[David Groves @pumplekin]

@pvshort @ianssmart I think you may be falling for Hanlon's razor here.

"Never attribute to malice that which is adequately explained by stupidity."

[David Groves @pumplekin]

@blondehunx Generally you don't.

You do need a Visa Waiver though (the ETA) to prove you don't.

Just as UK citizens visiting Schengen area countries now need a Visa Waiver (the ETIAS).

[David Groves @pumplekin]

@TomCayman @dhh Surprisingly, it is very similar in Westminster.

Both allow citizens of the Repubic of Ireland, or Commonwealth citizens with indefinite leave to remain to run for election. Holyrood allows anyone with ILR.

I don't like it, but its not a uniquely Scottish problem.

[David Groves @pumplekin]

@svpino My only problem is I'm already happy with the Framework 13 I'm typing this on that I'll be using it for a while !

[David Groves @pumplekin]

@yacineMTB Or just get the worst of both worlds.

1. Dynamically link everything.
2. Containerise everything.

[David Groves @pumplekin]

@CyberRacheal Likely but.

If the VPN was needed then all you have done is trade the coffee shop snooping for the VPN provider snooping.

The email traffic should be going over HTTPS/IMAPS/some other encrypted transport already.

Also in theory you can have unencrypted VPN's like RFC1853.

@CyberRacheal Broadcast addrs are all 1's in host part, and so must have least significant bit in addr set to 1.

Only D can be broadcast addr, as all others are even numbers.

But D doesn't HAVE to be a broadcast. In 192.255.120.0/22 for example, it is a host.
