• Apple CNA (Captive Network Assistant)

  Published 15/12/2022 Updated 19/12/2022
  Now I may be biased as I’ve had to work with captive portals and been annoyed by Apples sand-boxed captive network assistants web browser. Apples CNA sandbox browser does not allow any sort of persistent storage on the device. To the point where localStorage is outright disallowed and cookies are not stored between sessions. It’s also not allowed to open new windows/tabs as the browser only has the one window you get and won’t allow any attempts to get out of the sandbox by opening a new window or open some app. Read More...

  Matrix is in my opinion super cool. It’s a community driven chat system that supports end to end encryption and it’s even possible to run it peer to peer if all parties host their own matrix “homeserver”. There are an absolutely insane amount of these “homeservers”. It’s recommended you choose one that you trust but any server with the exception of the official matrix.org server should be alright. The official is always under heavy load and will appear even more sluggish than most servers. Read More...

• IT Apprentice

  Published 05/04/2022 Updated 18/08/2022
  This page on my blog serves as an index of technologies I’ve learned or became better at while working as an apprentice in IT. 😀 It also serves the purpose of the required documentation apprentices in Norway are supposed to do. 🤠 😳 It’s mostly in relation to stuff learned at SkyLabs AS where we run a captive portal service. But there is also some stuff from Sircon AS. Those guys run hosting services, with a focus on cPanel/WordPress shared hosting. Read More...
