Right, Now I Need To Set Up...

Oh.  I already did that, like, ten years ago, and it still works?

Huh.

System Updates

Made good progress on the HTTPS cutover today.

Two main problems:
  1. We need a wildcard certificate, because the rate limits for free certificates would take decades to secure all the blogs.
  2. Forms have to be explicitly HTTPS; implicit form actions are HTTP (unencrypted), and browsers don't permit HTTP form actions from an HTTPS page.
I've updated Minx to produce a [http.base] field that you can simply stick in front of any relative path that will automatically update for the HTTPS switch (and also if you change your blog address).

There were a couple of glitches while this was going on, but mostly it was confined to my blog.

Update: DNS changes have propagated, and I've set this blog to always use HTTPS.  All forms across all blogs should be updated in the system now to switch to HTTPS as it becomes available (this caused me the most pain).

Will continue testing on this blog before switching everyone else across.

Update 2: Bugger, got one of the DNS updates wrong.  Sites will load slowly for the next hour or so because they're waiting for a script to load from an IP that's blocked by our hosting provider (long story).  I could try to fix that, but it would take an hour to make and test the changes.  Some of the fancy features might not work while we wait for that DNS change to propagate.

Update 3: That's fixed now.

Update 4: Broke mee.im, which was depending on the old mee.nu DNS servers.  Fixed that too.

Glitch In The Matrix

Sorry, the backup script froze the database for a few minutes.  It's not supposed to do that, but it did.

And Now Its Time For Name! That! Moon!

Our earlier game of Name! That! Planet! found a winner perhaps a little too quickly, so this time we're going for something slightly trickier.

Doing some refactoring, and running the test suite repeatedly to check that nothing has blown up.  (Which it did earlier this evening.)  Performance is on a single-core Vultr VPS with 2GB RAM.  Production is a 6-core/12-thread Xeon 2620 v2 with 64GB RAM, so throughput will be quite a bit faster.

That's without any caching, too.

The Return Of The Database

Sorry, got impatient while doing the changes and pushed the server too hard broke things.  Only broke them a little bit, but once it's broken at all it takes 45 minutes to check the indexes and bring the database back online.

There's something not quite right with the storage on these KVM servers I'm using.  I'm probably going to switch back to bare metal servers for the databases.  VPSes are fine for apps and files, but databases need consistency.

New Toy: Arale

It's a Xeon E5-2620 v2 with 64GB of RAM and a RAID-6 array of SSDs.

It's very cheap because it's a 2013 system - not quite 5 years old - and they're small SSDs.  But it will do nicely to replace a couple of our other servers that are running with single SSDs.

It will be the main server for the new platform.  I was worried until the weekend that I'd need more CPU power than that, but the 5x performance gains I got from two days of intense optimisation mean that this little server will run like the wind.  In Kansas.  In May.

The 64GB RAM is nice too; the other server I got recently only has 16GB, which is adequate but not spacious.  I had been considering Digital Ocean because of the ease of use, but it would cost nearly 5x as much if I wanted that much RAM in one place.

...

And I have that stupid boot loader problem with this one too.  Digital Ocean does not suffer from boot loader problems.

Update: Well, that was weird.  Five-year-old hardware but a two-year-old operating system won't boot.  But a week-old operating system does.

Well, Ubuntu 18.04 here we go, I guess.  While fiddling around I turned it into a RAID-1 for boot and a RAID-5 for storage.  I'll probably keep that.
