It's killing me that @Cloudflare has invented a new set of rules called "Precursor Rules" that are separate from every other bot protection rule. To exempt an API, two rules now need to be added under both "Security rules" and "Precursor rules" Please fix @eastdakota 🥺

only found out about this today but you can get a @Yubico key with an offer from @OpenAI just go into security keys & passkeys > get a yubikey

@SoVeryCuul
The first “holy %{*#^” is at about 4:20, assuming one didn’t already spend it on the autonomously organizing agent swarm. Strongly recommend watching if you’re interested in security, AI trajectories, or even science fiction, because this is already above genre median in wowza.

@deedydas
Things I learnt after buying a house after 1 year and going through lots of shitty products and things and what I'd do know if I bought or build a house again: - home assistant + their HA Green (little box that's open source to connect all your devices with Home Assistant) - LG or Mitsubishi air conditioning in EVERY room, both cooling/heating, every unit should have its own outdoor unit, or you get annoying things like you can't cool one room and heat the other at same time! I think they're called mono splits - xiaomi air purifier in every room, big spaces get the big purifiers, smaller rooms small ones (most air purifiers are too small for the space they're in!) - a good smart lock, it's so good because you come home and your door auto opens (esp nice if you carry stuff) - matic vacuum (they gave me one so I have to disclose but it's GREAT, all the Roomba and Chinese ones suck) - unifi router with access points, outdoor extenders, cameras, doorbell, all PoE - starlink with local fiber backup - tesla dreamwall or other batteries sufficient to power for days (means like 4-8 batteries @ 13kwh per maybe!), then connect your freezer, fridge, stove, etc to it (heavy loads) so you can keep and cook food when shit goes down - related get a Weber Genesis gas bbq so you can always cook food, fun with friends too - solar panels actually sufficient to power (so like 30-50, crazy number but if you get like 15 it's just not enough?) - pool is honestly overrated, you'll almost never use it, also lots of maintenance (we had a massive water leak with a $10,000 water bill this month, so F that) - but u DO want a standalone jacuzzi, that's nice, with lights! - if you care about safety get steel doors with massive locks for other rooms, and make those safe rooms, so if someone comes in you have multiple layers of security - also get weapons to defend you and your family where legally possible! - garden should be permaculture kinda concept with vegetables, herbs and stuff you can grow to eat, like strawberries, rosemary etc - harvia dry sauna, and if outside, add a little changing room to it so you don't exit in the cold outside! - related, build a home gym, get a big power rack with cables, free barbell, smith barbell, everything built in, and then some dumbbells and kettlebells, and a gym bike like concept2, maybe concept2 rowing machine too, with that you can do almost anything to stay fit! then hire personal trainer to come to your house or you will never go! - ALL lights should be changeable to red at night, via home assistant, so you can make everything red at 10pm for sleep! - also get outdoor lights for fun and security (burglars hate lights) - ALL windows black out blinds on outside, for both security and just NO light during sleep - when you're not sleeping, get lots of sunlight, big floor to ceiling glass windows, it's great! - all doors to outside flat on floor level, no stepover edges (like in PT) - preferrably lots of land around your house so you're not close to any neighbors (neighbors are always annoying even if they're nice!) - fellow water kettle, fellow ode 2 coffee grinder - sofas, other interior, make sure to find natural materials, 99% of interior is polyester/plastic - LG makes the best TVs, end of story, but their software is shit and spies on you, NEVER connect them to the internet/WiFi, instead buy an Apple TV box and connect that, that doesn't spy on you and has no ads, then connect it with HDMI and you're good, also no annoying LG TV updates - re: TVs, people show these formulas of like blalba distance to sofa from tv is N meter so now you need 60", in my experience they always sell you a TV like 10-15" too small, we had 77" LG TV and it was like diving into the screen, beautiful, but then we followed the formula and changed it for 65", not the same! get bigger! - get a VERY big bed, 2m wide by 2m long at least, get natural bed sheets/duvet and seperate duvet from partner, the less you wake up when your partner moves the better - guest rooms are a bad idea, it's annoying to have friends and family IN your house for weeks or a month, good luck trying to have SEX! better get a small house or apt near for them or put them in airbnb!!! - add a delivery box outside ur house so delivery people can put packages inside without having to ring your doorbell 10x per day - get a $500 mini projector and big projection screen outside (or a white wall) so you can have movie nights outside w friends
@levelsio
If you wanna do it yourself, this is how: Buy (~15 min) 1. Cheap VPS from Hetzner or DigitalOcean (~€5-10/mo), Ubuntu 24.04, tick automatic backups at checkout 2. Add your domain to Cloudflare (free plan), switch nameservers at your registrar 3. Install Termius (SSH app) + Tailscale (private network) on laptop and phone, free tiers Lock it down (~20 min) 4. Generate an SSH key in Termius, add it to the VPS at creation. Keys only, never passwords 5. SSH in once via public IP, run updates, install Tailscale on the server, log it in 6. Disable Tailscale key expiry for the server (admin console, one click) 7. Verify you can SSH via the server's Tailscale 100.x address BEFORE the next step 8. Provider firewall: delete all inbound rules, allow only port 443 from Cloudflare's published IP ranges. No public SSH at all. You enter through the tunnel 9. Test from outside: public IP times out on everything, Tailscale IP connects. Server is now invisible 10. One SSH key per device. Phone gets its own key added to authorized_keys Install the brain (~5 min) 11. apt install tmux then install Claude Code (official native installer, one curl command) 12. Run Claude Code inside a tmux session so it survives disconnects and keeps working while your laptop is closed Hand over everything else 13. Write ONE long handover prompt telling Claude Code: the server facts, the security model (so it doesn't "fix" it), folder conventions (/srv/http/domain per project, one tmux session each), your preferences, and standing rules (confirm before destructive actions, new services bind to localhost/Tailscale only) 14. Make it write all of that into CLAUDE.md first, so every future session already knows everything 15. Backups before features: nightly job pushing your data to GitHub, tested, before a single page exists 16. Then let it install the web server (Caddy + Cloudflare DNS plugin plays nicest with the locked firewall), set up SQLite, deploy the first page From then on you never administer the server again. You open Termius from anywhere, on any device, and just say what you want. BOSH

@DavidOndrej1
☁️ I made my own little Cloudflare called Pietflare, it's a DDOS and probe detector with AI and with a central IP / ASN / country block list Each server (VPS) sends suspicious probes, or DDOS attempts etc, from the access logs to the central admin and each server pulls a central blocklist every minute and blocks it in Nginx It has a central dashboard where I can see any threats and then instantly block them but preferably the AI blocks it by itself
