Ask HN: Am I the only one who does *NOT* want IoT in their solar panel setup?
16 by harryvederci | 10 comments on Hacker News.
All solar panel systems I can find seem to require an internet connection. The (seemingly) best option I have found so far is a system with an inverter that only requires an internet connection during the initial installation, which uses a wifi dongle so I can probably unplug that afterwards. Even then, the manufacturer states that not having it connected to the internet voids their warranty, and I'm afraid the software might even have some kind of countdown where the system will stop working when it hasn't been connected to the internet after a certain amount of time. I am not interested at all in connecting something that should help me get off the grid to the internet. Combine that with security issues[0] and I'm starting to think we're collectively folding our arms behind our back and intentionally falling forwards. Maybe I'm too paranoid. Thoughts?

New top story on Hacker News: Did anyone else just get signed up for “Amazon photos” out of the blue for $60?
Did anyone else just get signed up for “Amazon photos” out of the blue for $60?

Today I got an email welcoming me to Amazon Photos, and another email saying my $60 annual subscription will renew next month. When I went to cancel, it said I would receive a pro-rated refund based on my last payment… in 2015: https://ift.tt/EUGHyKM I don’t remember ever using Amazon photos. Has this happened to anyone else?

Ask HN: Books on designing disk-optimized data structures?
10 by memset | 9 comments on Hacker News.
Are there canonical books, resources, or readings for how to design data structures that will be primarily read and written to a disk rather than memory? Most of what I learned in school about big-O assumes that, for example, random access is O(1). However, random disk reads are really slow due to spacial locality. People who write databases obviously have solutions to this problem - for example, DuckDB is based on a number of papers that have come out over the years on this topic. If I wanted to design, ie, a tree structure which was intended to be read/written from a disk, are there general principles or patterns the have been developed to take advantage of locality of reference, minimize random reads, or decrease the overhead of writes, that I could familiarize myself with? What is the CLRS for disk?
