My 91 gallon reef aquarium requires RO water for top-up as the saltwater evaporates. Usually you get a container, fill it with RO/DI water and have an auto top-up setup to keep topping up the tank as the water evaporates.\

The problem is that if the reservoir runs empty, you risk damaging the top-up pump (mine has a safety shutoff), but worse - you run the risk that the tank's sump runs dry and you burn out your main return pump.

I initially tried to use Neptune Apex' LLS-15 sensor but it turned out to be horrible. It would measure accurately down to about 12cm, then it would spike up to 18cm and stay there - while the reservoir runs empty. Recalibration did not help.

The new Apple Intelligence feature is helpful in many ways. However I just discovered one example where it increased risk, not reduced it.

It has a feature where it will auto prioritize emails and raise the mails it thinks is high priority, to the top of the list with a banner to emphasize its importance. Just... in this case, it emphasized a phishing email:

Why do companies think it is a good idea to ask you for a 5-star review? Can they not have more self confidence and ask for a review and let you decide how that review should look like?

I recently started up a 91 gallon reef aquarium. One thing that is unique about an aquarium vs other pets, is just how dependent it is on stable electricity. A cat or dog or bird won't care too much if the power goes out for a day, but fish, coral and inverts will die without proper water circulation - some will die within an hour or two with no water movement.

The electrical grid is very stable here in south Alberta. However it has gone out once or twice in the past three years. If you care for your reef aquarium inhabitants (which you should if you are in the hobby), you will need to make sure they are provided for when the inevitable strikes.

There are several ways to provide backup power for your aquarium. From least elaborate / expensive to most, here is an incomplete list: 1. 24V battery and a simple relay to switch power. 2. Dedicated aquarium pump / wavemaker backup unit 3. Small computer UPS 4. Large computer UPS with extended runtime batteries 5. Gasoline generator 6. Whole house battery backup such as Tesla's

I have been wondering a bit over the news that Apple Intelligence would include linking to ChatGPT and other LLMs from Siri when needed, as opposed to introducing their own-in house AI. With two trillion dollars net worth and a year lead time you'd think they can develop their own LLM model.

After my last post, I think the reason Apple did this is indemnification. They realize AI is shit, but also understand the pressure from their investors and the public to participate in the AI madness.

Clever.
