No we didn’t in practice - because you also need the return routability. Modern day example: If you are connected over WiFi and 3G over two different ISPs, the packet for your (probably RFC1918, statefully NATted by your home gateway) addre

The oddest part was that FFC recommendations didn’t include “limit the size of your broadcast domain”. Large flat L2 are a classic time bomb, with their builders proudly exclaiming “look ma, no hands!” until they painfully get reminded of t

Their point (in my interpretation) is with bare metal you can get more capacity than you need, for cheaper. With some cloudflare-ing you could quite easily get away with a single origin server in Germany, too. The latency from a rails app i

This is an intriguing quote. The biggest problem I saw with tcp over tcp is not during the regular operation, but when there was a noticeable packet loss present on the line. Then the the accumulated retransmits on stacked TCP most of the t

In general “checking whether the connectivity to internet exists” is an idea that may create a massive pain down the road when implemented, because the heuristics used are not equal to actual connectivity, thus will break one day. Just atte

Happy if it will be of use! There are two things at play with being too fast: first, you know what you are talking about (thus are giving a talk) - and tend to want to give as much info as possible. the second, and more important one, is th

+1 on needing to specify “serde” as a feature for chrono. Another one was needing to enable “huge-tables” for diesel itself - some of my tables from the “legacy” system have many fields.

Diesel.rs does give very scary looking errors but I found they are mostly due to the entire record structure being there as a (part of) type signature - after some time I started to get a “feeling” for what is wrong. Also, over time, as I g

It’s also that if the guidelines about the whitespace are so important, just automate the thing. I like quite a lot the approach taken at my $dayjob: the files that you change must not change if one uses ‘indent’ twice on them (twice becaus

The only small caveat that should go along with that: that there is no native IPv6 connection to the Internet, i.e. it is an IPv6-only hotspot with an IPv4-only uplink to the Internet. So, while the basic behaviour should be fine, it's

Indeed. Also, in 3GPP until Release 9 there had to be two PDP contexts per device - one for IPv4 and one for IPv6, thus resulting in performance issues, and licensing costs for some vendors too. This was fixed in later releases when a new t

Correct, it's not. It's shifted on the application developer, who is the "user" of the network stack.

Next time you reconnect your SSH session after changing from one WiFi network to another one, consider that this is a degenerate case of multihoming.

In addition to other answers, here is some food for thought: Some operators are already working on turning IPv4 off in their networks: https://www.youtube.com/watch?v=EfjdOc41g0s
