Hello, I'd probably start with an open source off the shelf solution such as https://www.home-assistant.io/ There are tutorials on their site that cover installation onto a raspberry pi so you should be able to get to and running fairly quickly. It sounds like a fun project so please do let us know how you get on.

We make a vertical distinction between visuals for UI (which are under the R&D department) and visuals for content management / site promotion (which are under the S&D department).

Manitoba Hydro implemented Sharepoint a year or two before I retired. Horrible system if you are expected to manage it without training (as was typical where I worked).

I am confused when you say the HTML time picker input box can be set to 20:00 for time in and 5:00 for time out, because `<input type="time" ...>` only allows the end-user to specify a time, not a time and date combination. Should it always be assumed that if the time out is earlier than the time in, that it is the next day? …

In other words, if you just need days or hours you can do something like `$diff->d` or `$diff->h` (All properties available [here](https://www.php.net/manual/en/class.dateinterval.php), but if you want to calculate a runner's start time and end time and then do something like "You ran the race in 08:33:56!" then you could use the `…

>Is that list incomplete or straight-up wrong? I have no way of knowing. If I add a bunch of numbers and get an answer, is it right or wrong?

Creating and removing database indexes is very complex and is not a matter of let's throw spaghetti at the wall and see what sticks. When working with big data, loads and loads of thought goes into each and every index. Nearly all indexes can work, but not as well as others might, and having too many indexes on a table can slow down inserts and …

I faced a similar problem when I created and maintained the corporate side databases to mirror the EMS (AGC/SCADA) real time data. One month of data was roughly 300 meg and it was critical that this be available 24x7. Sometimes databases break and it is important to recover them as quickly as possible. Knowing that around 90% of the queries were on…

I can see your rationale, but I don't necessarily agree with a separate table in the database for every month. There are much more elegant ways of handling that use case these days, especially in MySQL. You didn't specify how long ago this was. Either way, still hoping a MySQL expert can come along and answer my question here.

Your data wouldn't be accurate and incomplete, if either one of the performance schemas were off. event_waits_current was off, so MySQL didn't store the data (e.g., collect wait event data in detail), which can create incomplete or missing information about index usage like table I/O waits, index access details, event metadata, or timing and …

Re: How much anonymity does a VPN really provide?

A VPN helps hide your IP and encrypt your internet, so others (like your ISP) can’t see what you do online. But it doesn’t make you totally anonymous. The VPN company can still see your traffic (if they keep logs). Websites can track you with cookies, and if you log in with your real info, they know who you are. So, a VPN is good for privacy …

Re: Delete unused MySQL indexes

I thought it would be as simple as DROP INDEX index_name ON table_name; As for removing only unused indexes, I don't know how MySql would be able to determine if an index is used, or not. You'd have to decide. Since indexes are used to find things quickly I would imagine that if you delete an index and then take a performance hit it's …
