  • 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.
    



  • Note that this is not all writing of optical media, much less reading of optical media, but specifically packet writing, a comparatively rarely-used set of functionality to provide the appearance of limited modifiability on write-once media.

    https://en.wikipedia.org/wiki/Packet_writing

    Packet writing allows users to create, modify, and delete files and directories on demand without the need to burn a whole disc. Packet writing technology achieves this by writing data in incremental blocks rather than in a single block.

    Deleting files and directories of a CD-R using packet writing technology does not recover the space occupied by these objects but, rather, they are simply marked as being deleted (making them effectively hidden). Similarly, changes to files cause new instances to be created instead of replacing the original files. Because of this, the available space on a non-rewritable medium using packet writing technology will decrease every time its content is modified.

    I’ve burned many optical media discs, but never made use of packet writing.

    EDIT: I think that wodim is probably the most-commonly-used optical media burning software for data discs on Linux, and looking at its man page, it apparently never got packet writing support out of being flagged experimental, for perspective:

       -packet
              Set Packet writing mode.  This is an experimental interface.
    
       pktsize=#
              Set the packet size to #, forces fixed packet mode.  This is an experimental interface.
    
       -noclose
              Do not close the current track, useful only when in packet writing mode.  This is an experimental interface.
    




  • 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.


  • “Fallout is the big one,” Middler claimed. “There are multiple Fallout projects in development, including, as far as I’m aware, that one that I’m sure you’re all wanting. It’s not far enough in along to say anything like ‘you’re going to be playing this game anytime soon’.”

    Middler then joked, “Anyway, New Vegas 2, coming soon”. Is this the one we’re “all wanting”? Yes, but then also so is Fallout 3 Remastered, Fallout 5 and even a remake of Fallout 2. The fanbase is rabid, and hungry, and it’s been a long time since they’ve been fulfilled outside of Fallout 76 updates.

    I mean, if Bethesda released all four of those, I’d buy all four.

    I also don’t know what “Fallout 3 Remastered” entails, but if it means forward-porting the content to Starfield’s engine, that’d be pretty cool, though I do wonder how much effort will be required for mod-porting.

    IPv4 has some other features too.

    $ ping 0x8.02004010
    PING 0x8.02004010 (8.8.8.8) 56(84) bytes of data.
    64 bytes from 8.8.8.8: icmp_seq=1 ttl=116 time=22.8 ms
    

    That’ll be Google’s root DNS server, using hexadecimal and octal representations.








  • I’m not familiar enough with Cloudflare’s error messages — or deployment with Cloudflare — to know what exact behavior that corresponds to, but I’d guess that most likely it can open a TCP connection to port 443 on what it thinks is your server, but it’s not getting HTTPS on that port or your server isn’t configured to serve up the right certificate for that hostname or the web server software running on it is otherwise broken. Might be some sort of intervening firewall.

    I don’t know where your actual server is, may not even be accessible to me. But if you have a Linux machine that can talk to it directly – including, perhaps, the server itself – you should be able to see what certificate it’s handing back via:

    $ openssl s_client -showcerts -servername akaris.space IP-address-of-actual-server:443
    

    That’ll try to establish a TLS connection, will send the specified server name so that if you’re using vhosting on the server, it knows which site to return, and then will tell you what certificate the web server used. Would probably be my first diagnostic step if I thought that there was a problem with the TLS handshake on a machine I was running.

    That might provide enough information to you to let you resolve the issue yourself.

    Beyond that, trying to provide much more information probably isn’t possible without more information about how your server is set up and what actually is working. You can censor IP addresses if you want to keep that private.


  • I could definitely use a supplemental e-ink display, though I think that the touchpad is too small. E-ink works very well in well-lit environments, like outdoors in the sun, where LCD displays don’t do well.

    I think that a more realistic route for laptops to have a supplemental eInk display is having the laptop have a protective cover that flips open and sticking a touch e-ink display on the back side of the laptop lid. Then you use the laptop as a tablet in that mode. I believe I recall seeing a smartphone manufacturer that did a dual LCD-eInk display on opposite sides of the phone.
