  • chown changes the file owner. chmod changes permissions. So, if a file or directory is owned by root but a user should have access, you could make them the owner or you could keep root the owner and just allow read/write access.

    They come up more on servers where you often have multiple users with different access levels. Some users might not have sudo permission but do have full control over their home directory and whatever else they need. And web servers, for instance, will usually have a user called www-data or similar and it’s shared by all the users in the “developer” group.


  • chmod is the command to change user permissions. The numbers mean user, group, and others and the value allows read, write, execute. So, 000 means no one has permissions to get rid of the mount point. 777 means everyone has all permissions. (4 is read, 2 is write, and 1 is execute and the numbers are added. So, 644 would mean you can read/write, the group and other users have read only access.)

    You don’t have to use the numbers but eventually, almost every Linux admin does because it’s faster, a bit like a keyboard shortcut. But, for instance, you can add Execute permission with chmod +x /some/file/location.

    Here’s more details on the how to chmod and the historic reasons for the 0-7 system (spoiler: it’s 8 bits): https://www.redhat.com/sysadmin/linux-file-permissions-explained
















  • Ironically, New Orleans might be OK because we have elaborate flood control systems and have always dealt with flooding. Vulnerable places like the Netherlands and New Orleans are what we all assume will end up flooded. (And we will.)

    But we’re built for it. A river delta floods sometimes anyway. I’m honestly more worried about places where snowmelt creates small streams now but in the future, will just create terrible floods every Spring and then draught immediately after.

    To me, the scary part isn’t having water in the streets. It’s climate change. We had an issue recently where there wasn’t enough fresh water draining into the Mississippi to push the salt water back. It ultimately never reached NOLA but it reached plenty of people downriver. And because of a drought in the Midwest.




  • It would have to be game changing! Get it?!? “Game” changing?!? Ah, whatever.

    Awful puns aside, it really would have to be a major step up in hardware. The Steam Deck is a platform developers (plus accessory makers and open source devs for emulators and stuff) seem to care about. Even modern AAA game devs will often try to make their games playable on it even if they have to compromise. (It may not be technically possible or economically feasible but devs seem to all want to support the Deck even if their bosses have other plans.)

    At some point, it’ll be impossible for the Deck’s hardware to handle recent games and then we’ll all upgrade to something that sets a new baseline and strikes a better balance — whether Steam Deck 2 or a competitor. But my guess is that it’s going to be more about hardware generations than something Microsoft does. (Proton might be nearly perfect by the time Microsoft makes a decent controller interface and they seem to be focused on shoehorning AI into Notepad and Paint instead of doing useful things.)
