my hobby is finding new hobbies
Sounds a bit like me. I just retired in June and am busy setting up my workshop. The original intention was woodworking with a focus on boatbuilding. As I go, I realize that I'm actually headed more in the direction of hobby manufacturing: a variety of stuff in wood and metal with a side order of 3D printing. On top of rebooting my programming hobby of learning a new language every year from before I "sold out" to Visual Basic and Access.
Don't sweat it. I used to feel the same way. Then, somewhere in my 50s, I realized that I actually had already been doing what I wanted: everything. "Jack of all trades, master of none".
I did strive toward mastery of most things I tried that I liked enough to stick with for awhile. I like to think that I generally achieved competency, but I know that I had a few bosses and coworkers who would dispute that. :)
Learning new things and having new experiences is priceless. If you can find that within a particular career, that's fantastic, but it's not the only approach.
Are you sure that rounding was broken? Many systems use "Gaussian" or "banker's" rounding to reduce accumulation of rounding errors. Instead of always rounding to the next larger absolute value at .5, they round to the nearest even number. Although it introduces a bias toward even numbers in the result set, it reduces accumulation of error when .5 is as likely as as any other fraction and odd/even are equally likely in the source.
I was taught "banker's" rounding in school (graduated 1974) and have had to implement it a few times to reduce error accumulation.
If you are looking for a rabbit hole, Wikipedia has a pretty comprehensive article, including an example of how the wrong choice of rounding algorithm led to massive problems at the Vancouver Stock Exchange (Canada).
For anyone not sure what this is all about, CBC has a pretty good podcast covering the descent into medieval nonsense.
I had relatives living just a few miles away in one of the hotspots.
I recently retired from the local volunteer fire and rescue service. Several years ago the 911 dispatch service wanted to drop paging for notifications and move to SMS. I wrote a nice little technical critique of that plan. In addition to the basic issues regarding coverage (many members have no cell service in their yards, never mind in the fields, yet pagers basically just work), I learned from my technical contacts at the telco that there were a number of service guarantee problems. In addition to the lost and delayed message problem you discovered, things only get worse when crossing providers. As he put it, it's not so much that it works so good most of the time, it's that it works at all.
Dispatch did go with SMS notifications, but as an add-on to pagers and "robocalls" to registered phone numbers. We tracked notification channels for several months and found that with every callout, at least one member would report getting the SMS at least 20 minutes later than the page or phone call. Note that most members can get to the hall in 20 minutes or less. A couple of times over the years, we got a flurry of SMS notifications after we were on scene.
Friends don't let friends use SMS for urgent or critical communications.
Could it be that Stacer and file manager are somehow reporting usable space instead of "absolute" space.
I recall from the early days that there was overhead in the process, so that useable space was always less than formatted space. Perhaps that is still the case.
Did you try logging in anyway? Maybe their email notification glitched. I've signed up a few places without providing an email, then come back a day or two later to find an active account.
Edit: this comment changed my mind. In a nutshell, if we can't keep a large instance controlled by "the enemy" from destroying what we've got, then we just have to do better next time.
Yes, I would. Even if they are administered by people that have the best interests everyone at heart, sheer size means that they must be taken into account as the tools and clients evolve over time.
It's not that the system itself should be unable to cope with large instances, it's that the only reason for the system itself to gain that capability is in response to the rise or introduction of large instances. Some of what I've seen discussed is the need to change the development roadmap to accommodate the seemingly unexpected rise and possible introduction of very large instances. In other words, those instances are already controlling the direction taken.
I think it was 300 baud. I couldn't afford it, so followed the schematics to figure out how to connect a military surplus acoustic coupler modem at 110 baud. I didn't know any better, so I thought it was fantastic. Still, a few months later I got a good job and upgraded to an Apple//c clone and a 1200 baud modem.
My first modem was 110 baud acoustic coupler modem that I got from military surplus. I couldn't afford the modem Commodore sold for the VIC-20, so I figured out how to wire this thing in.
I didn't really do all that much with it, because not too much later I got a better job so upgraded to a Laser whatever clone of the Apple//c and a 1200 baud modem.
When I was looking at 3D printers, my wife asked me if I thought I could make money with it. I said "not in a million years." She asked me what I was waiting for, then. Two weeks later I was printing the test model! Sadly, I've made basically no progress with "real" CAD, so I do everything in TinkerCAD.
Fine woods and metals are crazy expensive, but if you keep your eyes open and aren't afraid to ask, a lot of pretty nice stuff is available for free or close to it as long as you're willing to put the time in on reclamation. I just got a nice Schubert chokecherry log for helping take it down and clean up. I got some sheet steel and light duty tubing from some discarded BBQs. And I've got more poplar than I know what to do with. Poplar is the go to tree for yards around here and there is hardly a week that goes by without someone taking down an old tree.
