Somewhat related, for fun sometimes id setup a QEMU VM with like 50 CPUs then boot something that shows the # and take a screenshot.   "hey, got a new PC"  

 

lol people fell for it every time.

That's a known issue when you have more than a thousand nested beast-hyves on a single machine.

macOS has its own set of problems in this area, however. Running
Docker on a Mac has always been painful, because it always involved a

fully virtualized (not just containerized) Linux guest. That's even
more painful on Apple Silicon.

Yeah. On my current Windoze machine I am virtualizing AMD64 on AMD64, and that is obviously the best case scenario, especially when running paravirt drivers for storage and network. Emulating an AMD64 on an M2 would necessarily be slower.

I may just ditch the whole thing and set up the tooling for development machines in our lab. Our cloud team doesn't really know much about the lab so they're not considering it (and I'm only part time on the cloud team so I'm not really directing things there). But they *are* building cloud-init scripts with the idea that development machines can have short lifecycles and quickly be replaced when there's a lot of new tooling available.

So I might just take the Mac because it sucks slightly less than windoze, and just put all of my Linux on the other side of the glass somewhere. We're doing cloud automation, not desktop software.

That feature is easy to turn off, and I had to turn it off, as it basically prevents charging during the day unless the charge is below 20%.  That feature has had my phone straight-up dying as I did a shopping order.

So its idea of "clean energy" is that the phone is charging at night time?

That's pretty dumb on its face, of course.  But it's got my gears turning.  Remember all the talk about data over power lines in the early 2000's?  The technology exists but it ended up not being feasible to deliver Internet connections over it because it was too noisy and nondeterministic.  I wonder if power delivery companies could embed a metadata signal into the wire to advise consumers about where the power is coming from at any given moment, and what the per-kilowatthour cost of the electricity is at any given moment.

The global warming people could use that metadata to figure out their carbon footprint.  The rest of us could use it to model our power consumption to favor the least expensive electricity available.

In the consumer world, time-of-day metering is restricted to "day mode" and "night mode" and we have meters that switch between them.  My home has this type of service, and I do save a bit of money by running major appliances such as the dishwasher in a delay mode that starts them up in the middle of the night.  It's also the reason why electric heat is reasonable here, since it gets coldest at night.  I imagine the same logic works for charging electric cars overnight.

In the commercial world, there is more granularity.  At my data centers for example, we use meters whose "total" kilowatthour count is only used as a reference; the actual metering is done in six minute samples and transmitted back to the power company over an out-of-band connection.  This allows us to take advantage of the best possible pricing, since our base load is consistent around the clock.   Yes, the air conditioners are working harder during peak load, but there's no way around that.

Now imagine a smart meter that has a two-way data connection with the power company and can really take advantage of spot pricing like we do in the commercial world.  *Now* you've got the ability to transmit metadata in the home's power line that can be received by phones and other chargeable devices.  Those devices could watch the metadata and figure out the best times to charge.

Or shut your power supply off. "sorry this power isn't green enough today".

From what i remember data over power lines was just too costly, and pretty much every transformer broke it.

IPoPDL (Internet Protocol over Power Distribution Line) is in use today.  The problem is the early experiments required 2-way communication, what is widely in-place now is 1-way.  Power companies use this with those stupid "eco thermostats" to turn raise the temperature in your air conditioning system, or disable it completely during high-load hours.

Isn't that just temporally shifting the high-load period?

Didn't realize they were using that to talk to your devices, i assumed it was cell data or something.  Related, how are they reading my meter remotely? They stopped coming in my yard to do it a good decade ago. Honestly never really gave it much thought.  I know our water "meters" were replaced and they drive past slowly with a stick to read them now.

On the consumer side, i used it for a while ( couple of years ) here at the house in a spot that was getting bad WiFi signal due to stuff in the walls, but due to old wiring, bandwidth was pretty poor so eventually did it another way.

HomePNA/HomePlug is not the exact same technology as IPoPDL, but of course it operates on a similar principle.

And yes, I would imagine it is far easier to "broadcast" some metadata towards the subscriber than it would be to get a full two-way network in place. Residential smart meters don't typically uplink through the power line. Some can be read from the street, some of them form an ad-hoc mesh network, and some are now being built IoT-style with 5G uplinks.

Smart thermostats are a good idea but they'd damn well be coupled with discounts on the electricity. No one except a few edge case freaks have any interest in being uncomfortable in their own homes simply as penance to Mother Gaia.
There's got to be some real cost savings. In my home I have independent line-voltage thermostats in each room, so a retrofit isn't really possible anyway.

I suppose that might be what they do here ( mesh ).  Truck drives past, never see it.    Used to see them in yards all the time, and asking to go into ours ( locked gate )

Pretty sure 3G was availble by then but they have not changed the meter in a while, so by now it would be dead without an upgrade i guess. Didn't think about that until just now.

I have a very sophisticate power supply system at home nowadays. You can adjust your consumption very well without real time information regarding the price of energy as long as you have a rough estimate.

Not that my system buys energy from the grid, but in case of failure/scarcity of my own power generation systems, it is programmed to buy power during cheap hours and store it in my battery banks. Power is only bought at more expensive hours if the batteries get to critical levels.

It would be cool to have it react to current electricity market prices. Currently I have some ad hoc script that delivers consumption estimates and battery states to my phone, which suits me fine XD

The new "smart" panels like the expensive one from Span are designed to handle that kind of thing in a medium to large size home. Charging and discharging is taken into consideration, heat and air conditioning are matched to the best power sources, and it can decide when to run auxiliary sources of power.
Sheddable loads such as EV charging are activated when the best kind of power is available.

That kind of panel would work well with a connection to the poco that reads in the spot power pricing. For the rest of us, though, it's just easier to say "run things at night when you can", especially if you have simple day/night metering.

On the other hand, a load center can last 50 years or more because it is such a simple piece of equipment. Even though I like electronic stuff, I'm not sure I want computers in the panel.

iTunes used to be a decent music player on Windows. I started it up for the first time in a year or so and needed to do a password reset to access the Store. NOW if you want to reset your Apple password and don't own an Apple device you have to confirm your phone number, confirm your e-mail, confirm your credit card, THEN wait 24 hours. I guess the money of us non-Apple owners isn't good enough for them anymore.

I had to get an Apple account for work. ( long story, long ago, office phone related, which i no longer have. So the # and ios link is gone )

Needed to use it for something some 10 years later for testing ( perhaps 4 years ago .. ).  It was impossible to get it working again, or create a new one with the same email ( office email, since it was work related and i needed our app-store entries ).   I think i had to wait 3 days, it wasn't hours, it was days.... then re-verify, then 10 more hoops.. one failed.  back to the beginning.. Rinse repeat, fail in a different spot.  Then 3rd time it just refused to even start .. 'screw you'.

Oh and i had the password stored in my vault, so i knew what it was, it just had not been used in enough time they 'disabled' it. Without that i doubt i could even have started their flawed process.

I had someone else test.

 

During the process, it appeared that it would be painless if i had one of their phones.  But no, dont want.

Subject: Mac OS as a daily driver?

[Reply] [ReplyQuoted] [Headers] [Print]


All sarcasm and MCIBTY aside ... here's a question to ponder.

I have recently learned that I will soon be given the opportunity to select a Mac as my work computer if I want it. (The only choices will be Mac and Windows, so please don't suggest any other options.)

My current work machine runs Windows 11 and WSL2. I spend most of my day in WSL2 doing devops type stuff, writing in Terraform and Python and Go and shell and that sort of thing, building automation and integration for data center and cloud operations. As an IT architect I spend the remainder of my time writing technical documentation, drawing diagrams, and being the Winston Wolf of the organization (I solve problems).

So my question to the audience is: will I find Mac OS a more comfortable environment than WSL2? The native side of Windows is of course completely unusable because production is all Linux and the tools just don't fit. Will Mac OS get close enough that I can sit at its native shell prompt and run Real Computer tools? Or will I find it "just different enough" to be problematic?

Complicating the equation is the fact that I spend 99.9% of my time on a VPN with only one IPv4 and one IPv6 address. WSL2 uses an on-host NAT to get to the outside world, and it also doesn't support IPv6 at all. We use IPv6 heavily.

Sarcastic answers are always entertaining, but I am looking for real answers this time.
