  • I’m interested to dig into how the HTGR works. I have what I would call an “average redditor” level of understanding about how graphite and heavy water regulated reactors work but I’m not one of those let’s go all in on nuclear Andys so I’m not up to date on the latest designs.

    My main issues with nuclear are the safety, costs compared to other green solutions like solar and wind, what to do about the waste and ensure that it is stored safely for the centuries or millennia that it needs to be stored safely, and how/where the raw materials are mined (see France wrt Niger). The article makes it out that this design improves safety so that’s good. I’m curious to look into how much it costs compared to the Westinghouse designed reactors that China is building (has built recently?) per kWh.







  • I don’t think you can extend a partition at the beginning, only the end of the partition. This is because the partition header and table is written at the beginning of the partition (i.e. the file system needs to know where to start reading so that it can traverse files and directories in the partition). To support resizing a partition at the beginning data would have to be moved to the new beginning of the partition, and exactly which data needs to be copied differs from file system to file system so it’s not something supported by a partition manager such as KDE partition manager. Therefore, the only way to do what you want is to backup the partition, delete it, and create a new partition at the beginning of the drive and the restore the contents of the partition.

    Extending a partition at the end is much simpler, basically some header just gets updated and says this is the new end of the partition, and then a file system specific command lets the files system know that you now have all of this free space available for use.
