It would work anywhere, but only with small amounts of current. In Germany the max is set to 800W. Won’t affect the grid much and standard wiring can easily handle 800W flowing „backwards“.

Germany has many rented apartments compared to eg the US. If you own a house, those systems make little sense. But for Germany, where many rent an apartment, it’s attractive for many. And the only way for many to ever profit from solar.

> The Level 2 engineer was rostered on-call and therefore was not available on site at the time of the failure. Having exhausted remote intervention options, it took 1.5 hours for the individual to arrive on-site to perform the necessary full system re-start which was not possible remotely.

Which shows that sometimes, remote isn't a viable option. If you have very critical infrastructure, it's advisable to have people physically very close to the data center so that they can access the servers if all other options fail. That's valid for aviation as well as for health care, banks, etc. Remote staff just isn't enough in these situations.

From the text it sounds like it looked up if a code was in the flight plan and at which position it was in the plan. It never looked up two codes or assumed there code only be one, just comparing how the plan was filed.

I'm sure there'd be a better way to handle this, but it sounds to me like the system failed in a graceful way and acted as specified.

But that wouldn't help you here. The flight plan will come in with the code and you'll still have to resolve that to your keys.

Transferwise makes sense to me. They used to be just about transferring money abroad. By now, they offer full bank accounts including card payments. I guess they dropped the transfer to make people aware that they’re a proper bank now.

As a website owner, I have an incentive to provide access to the Google crawler because of the visitors they send me. They've started to show more content directly, but a fair amount of people still click through to websites.

It looks to me like ChatGPT Search hides links much more. Is there any incentive for website owners to allow access to ChatGPT?

Yes, a lot gets lost in an email vs. video. I'm not saying it has to be a live meeting, but videos of execs talking about strategy often make their ideas much clearer than a written text.

And live has the big advantage that it cannot be re-recorded, so it's more natural and not as rehearsed as a recorded video.

Since most applications aren't latency sensitive, space and power can be nearly free by setting up the data center in a place where it's cold, there's nearly free electricity and few people live. Leaves you with cost for infrastructure and connectivity, but I guess electricity prices shouldn't be the issue?

Not true. I‘ve been at several companies that self host Jira. With the amount of critical data and processes in Jira, it can be comforting to have it on-prem with no one else being able to access the server.

Absolutely, takes me less than 10 seconds. And the process is transparent. Passkeys don't really seem to be faster.

I don't like passkeys. I'm not sure if I'm using it wrong, but it feels like entering a TOTP is so much faster and easier than using passkeys. It was always easy to enter a 6 digit code and have some back-up codes printed somewhere. Passkeys might be superior in some ways, but feel much harder to use. But then again, I'm also not an average user.

My employer uses alphanumeric 2 factor codes and I'm so certain that they have a bias towards some letters (mostly y and z). I know I'm probably wrong and it's probably because they appear so rarely in real words, but I can't shake the feeling they aren't random.

Only problem is that I don't have the algorithm. I started writing down all codes I got but since I only get 5 a week, it's a long process. I'll probably switch jobs before I have valid results.

Not that it would change anything, but I'd be really curious how biases in those codes could appear.

Too bad 4k projectors are still so expensive. I bought my 1080p projector 8 years ago and it seems like not that much has changed since then when it comes to prices. 4k projectors are still much more expensive than comparable TVs.

My biggest issue with Backblaze B2. It’s so much effort to get my invoice each month. I don’t get why companies send out billing emails but don’t just attach the invoice or insert a link directly to the invoice.
