Cloud formation is affected by cosmic ray flux. It's effectively random.
But the real problem is chaos - which says that even with perfect data, unless you also have computations with infinite precision and time/spatial/temperature/pressure/etc resolution, eventually you wind up far from reality.
The use of ensembles reduces the effect of chaos a bit, although they tend to smooth it out - so your broad pattern 12 days out might be more accurately forecast than without them, but the weather at your house may not be.
Iterative DL models tend to smooth it faster, according to a recent paper.
They partly broke hierarchical tags with the rewrite. If you have a tag hierarchy a.b.c and you put a note at a or b, it will not show up in the tag list. That ruined my main organizational tool.
And the limited depth of notebooks has always been just wrong, which is why I use hierarchical tags.
Apple may be upfront, but a couple of years ago they pretty much suddenly destroyed Progressive Web Apps by disallowing a whole bunch of modern, open standard browser capabilities, all in the name of preventing tracking.
A lot of developers were just crushed by that. Imagine having hundreds of thousands of dollars into developing an app when Apple just destroys the ability to do it.
When a big corporation has monopoly power (and Apple is very close to that - only one equally evil competitor in mobile space), they do bad things, often thinking they are doing good.
[caveat - there is so far an unofficial way to get around their "we will blow away your saved browser data" that was discussed by one of the webkit developers on the webkit blog. But since it isn't an official Apple doc - do we trust it?]
I was one developer who was burned. I was developing, as a volunteer, a web app for a very large volunteer organization. Boom... now it may not be possible, or if I use the work-around, it may be possible until it suddenly changes.
Standard Notes claims to, with a caveat that there may be a format it can't handle due to Evernote adding features.
A transfer-in from Evernote, either natively or through some third party utility, is a must. I'm not interested in writing something to parse .enex and put it into some other format (although .enex looks pretty easy to parse - it's xml with embedded BASE64 for some things like images).
It looks really, really interesting. But when you say it syncs super fast... is syncing initiated manually, or do you mean that changes on one device appear on another device quickly?
But I don't trust them and haven't since they made it difficult to export all of your notes. And, they damaged tag-based organization by changing to only list notes that are at the bottom of the tag hierarchy - not those in the middle.
And, they want to be the sole custodian my data, and I don't like a company with that attitude.
Having been involved with system design including large servers for 50 years, I don't trust the cloud. Yeah, the huge cloud providers are staffed by really smart people and it is very unlikely you'll lose your data there (although I sure wouldn't trust Google - they're nuts with their product management).
But a small staff Evernote, under pressure to please investors by somehow adding features that will let them compete in spaces already pretty full - no, I don't trust them to adequately use the cloud to keep my data secure.
I do frequent .enex backups of all my notes.
I haven't switched yet, because it's a pain. But I sure do backups frequently.
And if I see a good alternative (maybe in this thread), I'll jump on it.
As long as I don't have to do the sysadmin all the time (I'd forget - busy with other things, or I'd make some dumb mistake); and as long as it isn't a giant pain to install and build. And as long as it has clients for MacOS (including Apple ARM processors), Android and iOS... then I'll look.
Ideas sought.
The last time I did this search (2020), I didn't find one I liked.
As a co-founder, I'd say you can get wealthy or at least comfortable.
But, we started with two people. At some point we needed funding. That put us on a track of angel investors, VC's, and a cycle acquisition, buyback, funding, acquisition, buyback, etc.
As the techie guy, I found that tiring and distracting. When we changed from software as a product to SAAS, it got a lot less fun. When we grew to 2000 employees (mostly non-tech), the company was a pain.
So after 20 years (to the day), we sold it and moved on.
If you export it, you get XML, with embedded HTML in <CDATA TAGS, among other things. But the point is the same - it's not hard to parse. It also has base64 encoded images and pdf's. Don't know what else.
It's the problem that's hard.
