I recently set up kubernetes to run on an old laptop. The goal was two-fold, 1 learn kubernetes and 2 setup an instance of nextcloud. I've managed to set everything up with cert renewals for my domain and enabled dyndns in case my provider changes my ip. All well and good and quite nice learning experience! Now I would like to also start running my own email server and have some questions. Is ther any that have a helm chart that is easy to setup in kubernetes? Since I am running this from home I imagine I'm more likely to be classified as a spammer. What can I do to minimize the likelihood of that? I read somewhere about reverse DNS, but not entirely sure if it is possible to do given I am running it all at home via a regular ISP.

I have a Xiaomi Redmi 4X device with 2GB RAM and 16GB on-device storage.

Yesterday, I setup PostmarketOS on it, and it works well enough. WiFi and display work well, although no 3D acceleration and no telephony at all. As such, now it is just another device on my home network, except that I can ssh into it to do some basic stuff. Right now it is setup as a Syncthing node to backup my Keepass db and personal knowledge base written in org-mode, but I would like to use it further, and looking for ideas.

Two things to consider, though. First, I don't want it to overcharge and bust the battery. Before when it was on LineageOS, I had a magisk module acc so it would charge only 40-80%, and is largely the reason why the battery holds up pretty well after 5+ years without swelling. I will take further look into it over coming weekend and try to make something like it for the alpine kernel included in PmOS. Second, while on charging the phone keeps vibrating repeatedly. I have no idea how to fix that one, but would like to strat given pointers. (I have never done kernel dev in my life)

So, any ideas on what I can use this extra computer in my metaphorical basement welcome. Thanks in advance.

It is late... and I am pretty much finished with migrating to a new VPS provider. I got rate limited with two domains, but I'm running everything through Cloudflare. Do I need to bother with LetsEncrypt on the VPS itself? When I check the domains, the certs from CF are working nicely.

This is my first time using CF.

Quick edit while I pretend I can sleep.

I’m thinking that CF will cover me for 443 and route all traffic there. I’ve got wildcards set for domains with services that require other ports — which is working. All CF is doing is caching my sites, right?

Non-comp person here; is there a record for longest period of time a DDOS attack occurred on a website? Would it be possible to forcibly keep a site offline for an extended length of time with a continuous DDOS attack?

I'm currently developing a minimal userscript manager who's main goal is to be fully auditable by any user in only ten minutes or so - my prototype uses less than 300 lines of javascript, and I'm trying to keep it that way.

To get the codebase this small, however, I have to be very picky with what features I implement - most notably, the code editor has to be very barebones. Are there any features that I'd be shooting myself in the foot by not including?

For example:

• syntax highlighting
• cloud sync
• regex url matching
• fullscreen editor (currently, it's just a browser popup - the intention is that you write code elsewhere and paste it in)

Any feedback is greatly appreciated!

I've been learning a bit more Python, going through a Udemy course to expand my skills a little. One of the programs the course guides you to make is a little dictionary, but it currently only runs once and then quits.
I'd like to adapt it to use a nice TUI that keeps itself open until the user specifies they want to quit, using something along the lines of npyscreen. However, this library uses classes, and that's not something I'm yet familiar with. I'd rather have an understanding of what classes are, how they work, and why to use them before I take the plunge and start fiddling around with npyscreen (although I'd be interested to hear if you think that I should Just Do It instead).
Can anyone give or point me towards a good explanation of the what, how, and why of Python classes? Or better yet, a tutorial that will give me something to write and play with to figure out how it all fits together?
Thanks!
