    Extremely cheap per kilowatt? Every statistic out there that I’ve seen and that includes government funding, as well as construction and deconstruction costs, paints a different picture. Nuclear is only competitive with coal or the relatively underdeveloped solar thermal.

    In 2017 the US EIA published figures for the average levelized costs per unit of output (LCOE) for generating technologies to be brought online in 2022, as modelled for its Annual Energy Outlook. These show: advanced nuclear, 9.9 ¢/kWh; natural gas, 5.7-10.9 ¢/kWh (depending on technology); and coal with 90% carbon sequestration, 12.3 ¢/kWh (rising to 14 ¢/kWh at 30%). Among the non-dispatchable technologies, LCOE estimates vary widely: wind onshore, 5.2 ¢/kWh; solar PV, 6.7 ¢/kWh; offshore wind, 14.6 ¢/kWh; and solar thermal, 18.4 ¢/kWh.

  • When I installed Kinoite to start using Linux as my primary daily driver, the first thing I did was setting up Ansible, creating a new playbook and all Linux configurations I made from that point on, are only ever done through that playbook, which is backed up in my Forgejo instance. One command and everything is being set up exactly the way I want. It feels extremely liberating.






  • If you use feature flags, don’t forget to remove them after some grace period. Almost everything bad about feature flags that you can read online is related to long-lived feature flags and all the dead code and complexity involved. Adding a feature flags without a commitment and plan to remove them (the flag, not the feature), is asking for trouble down the line.

    It depends. Some hardware degrades gracefully while my current desktop system won’t even boot and throws error codes on an empty battery. It took me hours to figure out what was wrong the first time it happened.

    It turns out there’s still plenty I don’t know, and I spend much more of my time confused and frustrated than I did before. The cool part is that I’m now confused and frustrated by really interesting problems.

    This is spot on. Your whole response ist just a trove of insight, I wouldn’t have been able to articulate so eloquently.




  • As you mentioned, with Fedora the best alternatives are immutable spins. Updating means downloading a new base image, applying overlays and additional installations to it and on the next reboot you start from that image. You can configure it to keep as many previous versions as you need and boot into those directly on startup. Since you never change your current image once it’s built, you can’t break a known good system. You can only ever break your next version and in that case, just boot the previous.

    I’ve created an Ansible playbook that configures a vanilla Kinoite the way I want it. No need to back up the system if I can recreate it with less than a megabyte of text files. Secrets are in my password vault, personal files are in my personal cloud and get synced to and from the laptop continuously. I would never go back to backing up system files as opposed to recreating it with a playbook. That seems so wasteful in hindsight.
