IPv6 Is Hard 1 year ago

The big issue I've seen is that there are not clear wins for all the pain of IPv6. And the failure to provide a much much better ipv4 interop story out the gate (vs just trying to yell at everyone to switch) was a big big loss. So that means folks ended up having to run ipv4 to end devices in many cases and we have dual stack hell across the network.

For the 90%+ of network clients on-prem that play by the rules you are often supporting both DHCP and SLAAC on IPv6 networks (unless android has figured out DHCP).

Dual WAN redundancy on IPv6 in SMB settings is actually worse relative to a NAT and ipv6.

The subnet size /64 is stupidly large, and the number of available subnets you can easily get annoyingly small from most upstream providers.

Firewall filtering has to be modified or you get weird errors. People don't always like ICMP coming through the firewall.

It's does lots of things differently, but for what? We do prefix delegation with DHCP but can't use DHCP to assign address (we are supposed to use SLAAC) but still need DHCP for lots of other stuff? It's nonsensical - you end up with just way too much garbage.

The privacy extension stuff hits IPv6 hard. You have lots of auto-rotating addresses.

The number of times turning of IPv6 fixes weird glitches / timeouts / stalls etc is still crazy too me.

ATT (massive corp) requires end user devices request /64 subnets one by one - which most end user gear does not support.

Getting static ipv6 IP's (despite claims there are lots of them) is seriously hard from upstream providers in many cases - but IPv4 is trivial by comparison.

The list goes on.

I would have made the subnet size 32 bits. Expanded the network part. Maybe even reduced the overall size - 128 bits feel dumb with /64's as the smallest subnet? Then just go super high interop / overlay to IPv4 with great suggestions so folks could ship ipv6 only stuff (even with on device bridge to ipv4 so outbound interface is ipv6) and no new concepts unless clearly justified.

And the thing is - single node can still scale ridiculously high without the orchestration overheads of distributed stuff.

You can do dual AMD 192 core CPU's (384 cores / 768 threads) with 9 TB of memory and a 24 disk SSD array in a 2U box.

This is their somewhat muddy response to the “trolls” who might say

“Changing the license was a mistake, and Elastic now backtracks from it”.

We removed a lot of market confusion when we changed our license 3 years ago. And because of our actions, a lot has changed. It’s an entirely different landscape now. We aren’t living in the past. We want to build a better future for our users. It’s because we took action then, that we are in a position to take action now.

I thought unlogged was used so crash recovery would truncate / dump the table on a crash with 100% Dataloss but this let you put stuff on a tempfs / ramdisk?

NASA launch coverage has really improved. YouTube access is great especially as SpaceX has moved off YouTube quality also has improved. It seems the last year regardless what I think about SLS and some other NASA programs this is very nice to see. telemetry and video back, though still a bit weaker

School funding is diverted from classrooms but still goes to education. State superintendent level takes a cut down to county superintendents and programs down to local school district superintendent / admin / consultants.

If a private school did 35 kids in a class paying 35K (that's 1.2 million per class) they'd have teacher aids and amazing everything .

State budget act in CA is 23k per student. Wealthy areas for another 5-10k.

We have an amazing teacher fighting insane classroom ratios and requirements. At 1m a class it shouldn't be like that.

Does it have autocomplete on inputs?

Keyboard bindings for keyboard shortcuts?

Microsoft has made a bit of a hash out of windows gui app development so a small opportunity for alternatives.

RDS is 50 cents or less a day for postgresql on a three year term for a small instance.

I use AWS / RDS - I’ve got to believe RDS is spinning money for AWS because of all the parts I want to be reliable this is way up there.

This undervalues I think what Apple has delivered vs Microsoft and Samsung/android et so.

With windows you will be spammed in various tailored experience ways through notifications and search, random apps come pre installed on windows pro and the list goes on. Android comes packed with blostware and remote managers backed in from others to force / silent install crap. Cancelling payments can be a nightmare.

Apple is playing in part a long game. Dial back the crap to dial up the trust. Long support periods. Easy subscription cancels. The list goes on. Then they squeeze folks hard cost price side to make up for that for sure.
