In Toronto there is only daylight for 9 hours in winter
Yes surely some days are cloudy
So some days you get 5% capacity factor, and need some other energy source as well
So it harms the economics of the venture
Look at the profitability of companies building utility scale solar farms, they cost 100 million and the company hopes to get a 10% return and pay a 3% dividend.
They still have to contend with moving parts for tracking the angle of the sun, fans on inverters, contactors, clearing snow, mowing grass, site drainage, tornadoes etc, so sometimes it is not as easy as it sounds
All for a 7%? Why shouldn’t they just buy the s&p 500 and call it a day
>By default, all devices hit your main gateway through the wildcard CNAME. But you can override any individual device by creating a specific A record. Need to debug a misbehaving unit? Point it to your local development gateway. Rolling out to a new region? Route EU devices to Frankfurt without touching the firmware. Moving a customer to a dedicated cluster? Update one DNS record
>As for what's causing the gains, there have been a lot of low-level optimizations and enhancements to various Linux kernel data structures and the like this cycle. Offhand that's perhaps the possible explanation but will be interesting to test on more hardware and other configurations as time allows. In any case, with every PostgreSQL read/write workload tested there were decisive performance gains for Linux 7.0 on this AMD EPYC 9755 server.
I’ve had to add more confirmations as people connect remotely using VNC and accidentally click buttons which then have real world actions.
To catch them all it logs the user out so buttons which affect the process are disabled, but now it can be annoying to be logged out after x minutes and always logging in.
> Transformers and turbines of any significance are not off the shelf parts and can have lead times of years
Bloomberg had a decent article[0] about transformers and their lead time. They're currently a bottleneck on building. It wasn't paywalled for me.
"The Covid-19 pandemic strained many supply chains, and most have recovered by now. The supply chain for transformers started experiencing troubles earlier — and it’s only worsened since. Instead of taking a few months to a year, the lead time for large transformer delivery is now three to five years. " [0]
Enough for the entire grid? There are some amount of reserves on hand (eg drunk runs into a telephone pole), but nothing that could replace a targeted attack with the explicit goal of taking out the most vital infrastructure.
And those pole mounted transformers are tiny. The big ones require special transports and can weigh a few hundred tons. Some are so large they are best transported via boat if possible.
I still have two 2013 era t430s, one with windows 7 and one with windows 10. When browsing the web they barely feel any slower than my corporate supplied t14 gen 2 or p1 gen 6 both with windows 11 now. I guess that’s the price of security.
