It's not that weird, it's how TTLs work.

When your computer wants to know what server x.com is, it (oversimplifying a bit) asks its own internal DNS (Domain Name System) resolver, which asks your router's resolver, which asks your ISP's resolver, and so on, until an authoritative resolver is found.

Each of those resolvers, before asking the next one, has its own memory it can reference just in case it gets asked about the same address very often, because asking can be costly in terms of time (because you have to ask the next server for the answer OR because so many different request are coming in that it's difficult to answer all of them). This memory is called a cache, and everything stored in that cache is given a Time To Live (TTL).

When a resolver that knows the answer to "what server is x.com?" is found, it gives not only the answer, but also a guess at how long that answer is valid. That guess is the TTL for the next server's cache. This number is controlled by the owner of x.com.

What all this means is

  • If you expect that x.com should always resolve to the same server, the TTL should be very long (because you want the resolution to be served from the cache, meaning it's faster)
  • If you expect that x.com will change in the near future you want the TTL to be very short (because you want resolutions to reach your authoritative server and get the new server address)

And what THAT means, relative to this particular bit of current events, is that somebody fucked up. If this change was well-planned, then the TTLs would've been shortened in advance of the server switch, giving time for the downstream resolvers to clear their caches.

But that didn't happen, which means that when your device asks "what server is x.com?", it sometimes gets the answer from the authoritative server (updated correctly to point to Twitter) and sometimes it gets the answer from a cache (pointed at who knows what).

Basically, Elon once again rushed some shit through and sure enough it's a fiasco.

Rains when please?

Sooner than October would be great, but I'm not holding out much hope :(

I’m going to try my hand at writing a Lemmy bot that will filter out spam and help with the kinds of tasks moderators on Reddit rely on the automoderator for.

This sounds fun! If you find yourself having trouble or just want a hand, I'd be happy to throw some energy/time at something like this too!

If you haven't already come across him, Jens Larsen is a great teacher with an excellent YouTube channel. He's got loads of beginner-friendly videos but a lot of advanced stuff to think about too, and he puts out a lot of fresh content here and there for picking up tricks and chord voicings.

Maybe not exactly beginner-level stuff but Ted Greene was also an incredible teacher, particularly of chord melody playing. His students have assembled a bunch of his material online in a way that's fairly accessible at tedgreene.com. He wrote a lot of stuff in a sort of idiosyncratic notation but once you figure it out, his arrangements are amazing. There are really powerful ideas in there about sticking to small movements for pleasant voice leading, using voicings that support lots of different choices of melody note, etc.

Well that looks fantastic. I'll have to give it a try next time I'm there. Solid rec!

That track sounds good!

I feel ya re: life changes. The great thing about music, in my experience, is the way it can connect you to a community that can help you navigate the sort of transitions in life you're talking about. I divorced an addict many years ago and really struggled to put my life back together after all of that, but I found a community in the local jazz scene that was supportive and healthy in a way I hadn't experienced in a long time. Being around those people in that moment and having a reason to keep improving myself probably saved my life.

I hope your musical journey is a happy and healthy one, friend.

I always get sidetracked with Miles because he worked with (and in many cases helped to launch the careers of) so many incredible musicians. It's super easy (but also super rewarding) to pull on the "oh I like that solo, who is that?" thread and unravel an entire career's worth of incredible music.

It's out on bandcamp if you want to support the band more directly, but yeah I think it's supposed to hit the streaming platforms soonish (couple weeks?)

Nice! I started out in a very similar place actually (working with a looper, trying to build interesting progressions to practice soloing over).

Do you record/post any of your stuff?

KNOWER has a new album out that's pretty bangin', and Louis Cole's "Some Unused Songs" has been nice to put on while I'm working.
