How would I even host a website at home? 20 years ago I knew how to get a fixed IP from my local ISP but I don't know how to do that anymore.
Reverse proxy with a dynamic DNS server (DuckDNS for example)

#132Interesting and non-obvious fact about solar panels...
The optimal angle for generating as much power as possible from the panels is very different to the optimal angle for powering something year round.
If you want to power something year round, it's the power in winter you need to maximize - so you angle the panel very steep to collect winter sun. In the summer, this angle is far from optimal, but due to more hours of sunlight there will still be plenty to power whatever device it is you want to be always powered.

#133I think this also shows how inefficient modern website hosting is. The fact that this person was able to get a raspberry pi to host the #1 website on HN powered by a small 50 watt solar panel is very cool (meaning maybe 10w average power budget), but also shouldn't be as uncommon as it is today. To put this in perspective, a modern server uses 50-100 watts idle doing nothing, and many more under load. To handle the t…
I hate to be that old foggy but, aren’t websites just getting worse and bloated with JS crap? I’ve had a couple websites I use daily for work just get flashy new interfaces which causes 1/3 to 1/2 second delays in the interface which used to not exist, previously they just had normal page load delays. For example, SalesForce Lightning, their UI overhaul. Old UI is mainly just flat HTML with some loading on fields. Ne…
We’ve recently transitioned to Salesforce for a project. It’s remarkable how laggy the interface is. Removing a line from a quote takes three clicks and four seconds. The UI also doesn’t always refresh the items in a reasonable period of time, requiring a page reload.
Reloading the page is like 20MB as well. Great when you’re tethered to your phone.

#134ICANN should make a .solar extension with the caveat that you have to provide evidence yearly that all IPs mapped by the domain were running on solar power
Maybe leverage "specialization + trade" and have some 'SCDN' (Solar Content Delivery Network).

#135My own battery + solar powered blog [0] is 100% inspired by lowtechmagazine. I am based in The Netherlands and due to my sub optimal location, I have to cheat in the winter by recharging from mains about weekly. I still do get some sun, but nowhere nearly enough to get through the day, let alone the night. [0]: https://louwrentius.com/this-blog-is-now-running-on-solar-po... And lead acid is also terrible for solar ap…
Lead acid have the advantage of being easy to buy and needing no balancer. Also they don't get damaged by overcharging. They handle full deplation way better too. Also lower initial cost.
Lithium batteries don't need a balancer either. I've been running a 3.6kWh pack of 12 cells for almost 5 years with no BMS or balancer.
I bottom balanced all the cells before building the pack and setup my chargers to only go to about 98%. This leaves more than enough leeway to avoid problems if one or more cells drift.
I've rebalanced a couple of cells once because they were off by a few hundreds of a volt. They're probably about due for another minor rebalance.
That said, this is in controlled conditions with regular use and monitoring. The cells are LiFePO4. I wouldn't run other chemistries without a BMS. Next pack I build will be much larger and have BMSes for safety and so I don't have to think about it.

#136When the server is down you can get the offline version of it. AKA the Printed Website. https://www.lowtechmagazine.com/2021/12/printed-website-thir...
I bought both volumes last year and made a point of only reading them outside by sunlight.
It's great stuff, very thought provoking. One of the many points that has really stuck with me is how the invention of the typewriter allowed us to write five times faster... and as a result we now spend most of our time typing, somehow.

You can use dynamic DNS if the IP address you're getting is a public one.

JS bloat can have significant server overhead when data is loaded dynamically. It’s generally more efficient to have one GET request that can be heavily optimized than a lot of tiny XMLHttpRequest that need to be parsed separately. That may flip around when someone spends a long time interacting with a SPA, but there is plenty of truly terrible code in the wild.
> It’s generally more efficient to have one GET request that can be heavily optimized than a lot of tiny XMLHttpRequest that need to be parsed separately. Without context, this statement is misleading at best and downright false at worst. You’re right that splitting up a single request into multiple would incur a small performance penalty, but you also generally gain other advantages like more localized caching and t…
The context was JS bloat, so we are specifically talking about the subset of poorly written sites. When it’s possible to shoot yourself in the foot many people will do so.
That said, if you ever actually profile things you will find the overhead per request is actually quite high. There is a clear tendency to request far to little data at a time.

Hmm ok. My experience with Lithium batteries is with EVs. Do you have a low discharge rate on your pack? Because the EV battery pack needed balancing like every charge. Otherwise it has to be a quality difference.
