Self-hosted email is losing to Gmail's hard SMTP rejections. Self-hosted password managers are split down the middle. And self-hosted music is doing the opposite of what you'd expect.
Part 1 ended on a 70-gigabyte breach in 2021. Since then, hacktivists derailed trains, dumped molten steel on camera, and reached grids in three countries.
Every entity, every block update, every redstone pulse — one thread, twenty times a second, 50 milliseconds a pass. Folia's answer is to stop sharing the kitchen. Here is the tick budget and the ownership rules, read from the PaperMC source.

After five years, Stalwart hit its first stable release on October 26 with benchmarks claiming it beats Postfix and Dovecot in 35 of 38 head-to-head tests. Every one of those numbers was produced by the vendor.
Two critical PHP flaws landed October 21 and were in CISA's exploited-vulnerabilities catalog five days later. The 9.2 score isn't the part that should bother you. It's where the bug lives — it goes off while PHP is still assembling $_POST, before a single line of your application has run.
Vaultwarden gives you a Bitwarden-compatible password server in one container and about ten minutes. The defaults that make that possible leave org creation open, audit logging off, accounts on PBKDF2, and a rate limiter that trusts a header anyone can set.
Eight eMudhra intermediate CA keys turned out to be recoverable from their own public certificates. Not stolen — computable, because the key generation produced almost no entropy. A researcher pulled all eight in under a second and signed a message with each one to prove it.
I could spot a nulled forum in about four seconds, and it never stopped being funny. Here's why the copyright line gives it away, what a measured 97% of nulled add-ons actually contain, and why MyBB quietly became the smart choice for everyone who wanted the look without the paper trail.
A Minecraft host has one port that must face the internet and a dozen that must not. The JVM flag that turns your server into a remote shell, the protocol that broadcasts its own password, the SSH default that is actually the problem, and the second computer inside every dedicated box.
A fake GTA 6 ISO used a believable installer error to cover remote-access malware, browser-data theft, and destructive file wiping. The “License not found” message wasn’t the crack failing. It was there so the victim would stop looking.
Game AI isn't intelligent. It's state machines, search, and scoring arranged to feel like judgment, with real, runnable code from FSMs to local LLM dialogue.
The 1971 Fikes & Nilsson paper that invented STRIPS planning, read firsthand — and the four changes F.E.A.R.'s GOAP made to run it in real time.
Self-hosted email in 2026 comes with more choices than ever. This guide compares Mailcow, Mailu, and Stalwart across security, performance, resource usage, scalability, administration, and deliverability to help you choose the right mail server for your needs.
The smarter our AI assistants become at remembering us, the more important it becomes for them to know what not to remember.
Four tools solve four different problems that all get pitched as the same problem. Here's what each one does, where each one breaks, and the combination that covers a real homelab without paying an SSO tax you didn't see coming.
