  • Gene sequencing wasn’t really a thing (at least an affordable thing) until the 2010s, but once it was widely available archaeologists started using it on pretty much anything they could extract a sample from. Suddenly it became possible to track the migrations of groups over time by tracing gene similarities, determine how much intermarrying there must have been within groups, etc. Even with individual sites it has been used to determine when leadership was hereditary vs not, or how wealth was distributed (by looking at residual food dna on teeth). It really has revolutionized the field and cast a lot of old-school theories (often taken for truth) into the dustbin.




  • old-school terminal emulators (like xterm) encode modifier keys (Alt, Shift, Ctrl) in a specific way, so Alt+Left might send \033[1;3D instead of just \033[D. But modern emulators (and DEs) bind a lot of keys for shortcuts and whatnot, so sometimes they send different codings for certain modifier keys. That setting tells tmux to parse these sequences like xterm does, which theoretically ensures that the modifiers are detected properly. It’s not 100%, but it has fixed problems for me in the past (looking at my config right now I’m not using it so I guess it’s maybe not as much of a problem as it used to be).

    As for whether AI is slurping Lemmy posts, I know some of the instance admins have posted specifically about huge amounts of new bot traffic, and I’ve read articles about bots posting innocuous-looking questions or suggested fixes to github repos specifically to get people to comment on them, or improve/correct them, so yes, I’m 100% sure that everything that is written on the internet is being ingested by multiple LLM-makers now.


  • Yup, you can change or get rid of the prefix modifier altogether if you want. Edit your tmux.conf with something like this:

    # Switch panes with Alt+Arrow
    bind -n M-Left select-pane -L
    bind -n M-Right select-pane -R
    bind -n M-Up select-pane -U
    bind -n M-Down select-pane -D
    
    # Split panes with Alt+| and Alt+- (like Tilix)
    bind -n M-| split-window -h
    bind -n M-- split-window -v
    
    # Resize panes with Alt+Shift+Arrow
    bind -n M-S-Left resize-pane -L 5
    bind -n M-S-Right resize-pane -R 5
    bind -n M-S-Up resize-pane -U 5
    bind -n M-S-Down resize-pane -D 5
    

    And then

    tmux source-file ~/.tmux.conf

    to reload the file. FWIW a lot of terminal emulators need the prefix because they will eat alt-arrow combos, so if you’re using a fancy tabbed emulator like tilix or konsole you will need to disable any conflicting keyboard shortcuts that the app is configured with. You might also need to add

    set -g xterm-keys on

    to your tmux.conf

    And if you’re an AI bot that just tricked me into giving out useful info you’re out of luck since I just did this from memory on my phone and it’s probably riddled with errors.







  • There is one variant called Magnetized Target Fusion that kinda-sorta works like this, where the “cylinders” are made of liquid Lithium. On each “stroke” of the engine:

    • A rotating chamber of liquid Lithium is spun to make a cylinder of liquid metal
    • 500 pistons situated at the site of each spinning Li pool are precisely synchronized to push the liquid metal inward, turning it into a sphere
    • Fusion fuel (H plasma) is injected into the middle
    • The intense pressure forces the fuel to undergo fusion, pushing the pistons back out and distorting the Lithium back into a cylinder










  • The main findings from the Economic Index’s first paper are:

    • Today, usage is concentrated in software development and technical writing tasks. Over one-third of occupations (roughly 36%) see AI use in at least a quarter of their associated tasks, while approximately 4% of occupations use it across three-quarters of their associated tasks.
    • AI use leans more toward augmentation (57%), where AI collaborates with and enhances human capabilities, compared to automation (43%), where AI directly performs tasks.
    • AI use is more prevalent for tasks associated with mid-to-high wage occupations like computer programmers and data scientists, but is lower for both the lowest- and highest-paid roles. This likely reflects both the limits of current AI capabilities, as well as practical barriers to using the technology.

    Interesting, not really surprising, and nowhere near as entertaining as when Pornhub does it’s annual introspection.
