  • How to look it up:

    M-x org-mode RET
    

    That’s “Meta-X” (Alt-X), then “org-mode” and Enter, switches the major mode of the current buffer to org-mode so that we have the org-mode keybindings active.

    C-h k C-c C-x C-l
    

    C-h, Control-H, is the “help” prefix. “C-h k” is describe-key, tells you what a given key sequence runs. C-h k C-c C-x C-l will say what C-c C-x C-l does. It gives the following output:

    C-c C-x C-l runs the command org-latex-preview (found in
    org-mode-map), which is an interactive native-comp-function in
    ‘org.el’.
    
    It is bound to C-c C-x C-l.
    
    (org-latex-preview &optional ARG)
    
    Toggle preview of the LaTeX fragment at point.
    
    If the cursor is on a LaTeX fragment, create the image and
    overlay it over the source code, if there is none.  Remove it
    otherwise.  If there is no fragment at point, display images for
    all fragments in the current section.  With an active region,
    display images for all fragments in the region.
    
    With a ‘C-u’ prefix argument ARG, clear images for all fragments
    in the current section.
    
    With a ‘C-u C-u’ prefix argument ARG, display image for all
    fragments in the buffer.
    
    With a ‘C-u C-u C-u’ prefix argument ARG, clear image for all
    fragments in the buffer.
    









  • Setting aside the specifics of the case, I do think that from a UI standpoint, cars either need to support being left in park without the climate control eventually cutting off or be so extremely clear that this will happen that it would be extremely difficult for a user to miss, as this is a legitimate example of a “fail-deadly” feature.

    IIRC from reading comments from people who have slept in their car and very much want the ability to leave the climate control system active, at least some Toyota models do support leaving the climate control active for extended periods of time, but the car needs to be in “Ready” mode. It was not immediately obvious to users that this was the case.





  • Anyone tried water purifying tablets yet, and would you recommend them?

    They’ll kill bacteria in water, though obviously they can’t pull chemicals out of it.

    I wouldn’t be worried about bottled water going bad after a year — I’ve kept distilled water for much longer than that — but if you want more capacity in a smaller package than by storing water, you can get a water still, distill water yourself as long as you have some source of water and some sort of sufficient heat (e.g. a fire).

    If you don’t have access to a water source but have sufficient electrical power — which in the past I’d have said probably isn’t very likely if the government can’t get water to the public in 72 hours, but isn’t as crazy as it once might have been, what with people running around with beefy home solar setups and the like — it’s possible to run devices that condense water out of the air off the cold side of a heat pump, these sorts of things:

    I’d guess that for most people, the most-practical and cost-effective approach is probably just to estimate how much water one might need and store that much potable water in advance. That takes care of the “have a source of water”, “get any energy required to purify it”, and “purify it” points all at one go. Doesn’t require a lot of expertise, effort, or place constraints on your environment to open a bottle of water.


  • Earlier this year the European public was urged to stockpile enough food, water and essentials for 72 hours to cope with a military attack, natural disaster, power cut or major industrial accident.

    Honestly, unless you have some sort of serious medical condition, most people should be just fine going 72 hours without food. We’ve a social convention of eating three meals a day, sure, but your body is quite able of running off stored energy for a long time. I’ve fasted for a week myself for the hell of it. I remember mentioning that to an aunt once, and she mentioned that she’d done two weeks.

    This guy did over a year (though he was pretty heavy to begin with, had plenty of fat reserves).

    Barbieri went from 456 pounds (207 kg) to 180 pounds (82 kg), losing 276 pounds (125 kg) and setting a record for the length of a fast.






  • Depends on the game.

    I think that they have been used effectively in games like Starbound and Terraria or many roguelikes and roguelites.

    I think that there have been some games where they do not work well.

    Starfield has a beautiful terrain generator, but different terrain doesn’t really change gameplay, nor does combat really scale up to making use of very large maps, so you have the ability to explore infinite expanses of planets, but it doesn’t really provide much in gameplay terms. Aside from finding a cluster of useful resources near each other for an outpost, which isn’t that interesting from a gameplay standpoint and doesn’t need most of the terrain generator’s functionality, it’s mostly just cosmetic.

    I think that they work best where how you play the game changes substantially based on the mix of features of the dungeon. Then throwing a new mix each time at the player helps keep things interesting.
