Recommend me a LaTeX/TeX live equivalent app for Android
  • Joplin is FOSS & supports live LaTeX. The editor is markdown & you use $ for inline LaTeX & $$ for full line.

    They've got both desktop & mobile versions. One of my favorite apps.

  • What was the last skill you learned and how?
  • I recently learned to whistle as well! (in my late 30s). I'm bad at it, but finally can make a recognizable tune.

    More recently though I've learned to cut my own hair :)

  • What are the best Halloween-themed music for today?
  • My favorite Halloween playlist. I return to it every year!

  • *Permanently Deleted*
  • I don't remember all of the details, but I thought it was essentially the water's surface tension that foots the energy bill when climbing a paper towel or a capillary in a tree.

    The surface of fluids like water are unhappy. Molecules on the surface would much rather be deep in the fluid because on the surface they have "dangling" Van der Waals & polar bonds to one side. You can calculate the potential energy of the surface due to all of those dangling weak bonds, & that's the energy that is used to climb a capillary (the energy isn't free).

    I could be misremembering though, I admit. School was many years ago...

  • Some Halloween Rom Hacks
  • Earthbound: Halloween Hack was really great! I played it this season. I wish it were longer though.

    Thanks for posting the others! I'll check them out!

  • How do adults find happiness in life?
  • Small things. Sounds. The temperature of the air. The fact that my side isn't hurting right now. The kids costumes who were just trick or treating at my house.

  • What’s the oldest you can be to go trick and treating?
  • I'd rather teenagers be trick or treating than doing other stuff. If they come to my house they'll get candy for sure.

  • Older protagonists in retro games?

    I just got Strago in Final Fantasy VI (SNES version), who is a playable character who is ~70 years old. Got me thinking that you don't see many older protagonists in games, maybe especially retro games.

    I remember the elderly wizard from The Immortal (NES), but I can't think of many more. I guess retro games were largely targeted at children so most characters were very young.

    Do any older protagonists come to your mind in retro games? Or similarly, any retro games whose subject matter deals with aging?

    Straight men, what's the weirdest thing you've been told you can't do because it's gay?
  • Putting a wig on my best friend and spooning him while he's asleep.

  • Lemmy 100%?
  • If it's a topic I'm super passionate about & there's no community on Lemmy then sure. But I'm not going to start a new Lemmy community every time I want to post a random dog photo or whatever.

  • Do you leave your consoles on?
  • In ye old'n times we would leave the console on as a stop-gap way to save the game between in-game save opportunities. Because ye old'n times game design philosophy believed that the added difficulty of crazily separated save points was "fun".

    In modern times I sleep the hardware if I expect to be back within <24 hrs, and power off if I expect to be longer.

    (Thank god for saving memory states in emulators!!! Elsewise I probably wouldn't play retro games at all.)

  • Lemmy 100%?
  • I'm Lemmy 99%. Can't do 100% because sometimes there isn't an equivalent community on Lemmy so I have no choice but to use Reddit.

  • Political signs in public spaces

    They're legal, but such an eyesore. Every street corner is a cacophony of overlapping signs. What a mess.

    I don't have a problem with political signs in people's yards (on their private property). But geez, all this garbage in all our public areas make our town look like a landfill.

    Foss app to block spam calls (android)
  • Ugh, you're right! I didn't realize. I'm going to give SpamBlocker a try instead. I just downloaded and flipped through the options and it looks better than "Yet Another Call Blocker" anyway.

  • Foss app to block spam calls (android)
  • You're right, I hadn't noticed that.

    Looks like the F-droid version is way behind, because you can see on their GitLab page that the project is still maintained. It'd be best to get the app directly through GitLab I suppose, or add an F-droid repo that has a more up-to-date version.

  • Foss app to block spam calls (android)
  • It can block hidden numbers, if that's what you mean by "private".

    I hope you like the app!

  • Foss app to block spam calls (android)
  • Yes. Go to settings and toggle the Block hidden numbers option

  • Foss app to block spam calls (android)
  • I use Yet Another Call Blocker. It has a custom block list you can use to block a specific number.

    The block list also supports wildcard characters, which is my favorite feature! I use it to block swaths of numbers (much of my spam comes from the state I used to live in, so I block those area codes).

  • minetest changes name to Luanti
  • "Minetest" was a clunky name. Wish they'd have changed the name sooner.

  • Besides bars/clubs/restaurants, where else do you go/do when you want to get out of the house?
  • I wanna try a drive-in movie! But I guess they were before my time... :(

  • Has anyone added the VPN to your router, and what has the experience been like?
  • I set up ProtonVPN on the router for a few months & the family hated it. HATED IT! They were constantly asking me to disable the VPN so they could log in to a site here, or make a credit card payment there. It was a mess.

    Eventually I just disabled it on the router & ran my VPN at the device level. Much better now & the family doesn't hate me! :)

    Bad electrical component draining battery?

    I've acquired a classic 1977 124 Spider that hasn't seen much action in ~1 decade. I've had it ~1 week & the most important stuff works. I've done a number of small trips around town. Yesterday in the garage I wanted to catalog everything that needs repair by flipping all knobs/switches and marking what's not working. I found that the wipers don't work (but the wiper fluid pump does) and the cabin air/defrost fan doesn't come on, and one of the air levers is locked/frozen. I left the car for a couple of hours and when I returned I thought I could smell plastic burning. I hunted for the smell & found a small electronic component under the hood that seemed like it might be hot, but I wasn't sure. I left the car overnight with the hood up and when I returned I the smell was gone but the battery was dead!

    I figured I must have left something on by mistake so I went through all knobs/controls using the owner's manual to make certain that everything off (it was). Then I jumped the car & drove it around for ~20 minutes. Left it in the garage ~1 hour being very careful that the doors were closed, no lights were on, etc. & checked on it to see if the burning smell returned (it hadn't). Left it overnight & in the morning it was dead again!

    I don't think that there's anything wrong with the battery or alternator because it had run fine all week with multiple short trips around town. I think it's more likely that an electrical component is shorting somewhere & draining the battery. Perhaps turning knobs & flipping switches pushed an old brittle electrical part over the edge?

    My question is: what is the best way to find the malfunctioning electrical component? I was thinking of the following:

    • Jump the car & recharge battery by driving around town

    • Park in the garage and disconnect all fuses

    • Return every ~8 hours and check the battery, if it looks OK then replace a fuse

    • Repeat the above step until the battery dies

    Using that approach I can isolate the bad component to the circuit running through that fuse. It's a slow process though, is there a faster or more efficient way to do this? Any other ideas as to root cause? Any thoughts appreciated, thanks!

    Stuck in synchronization loop (Android)

    Got a new phone (Pixel 4, DivestOS) & trying to sync my notes via Joplin Cloud. It grabbed older notes ok, but seems to be stuck in an infinite syncing loop & never gets notes from the last ~6 months...

    Here's what I've done

    • Downloaded Joplin from F-Droid -> logged in to Joplin Cloud -> Added encryption master password -> synced. Result: old notes are there, new notes are not, infinite sync loop
    • Uninstalled Joplin
    • Reinstalled Joplin from F-Droid -> logged in to Joplin Cloud -> synced (older notes come in, newer notes do not) -> Added encryption master password -> synced. Nothing new arrives but I get an infinite sync loop

    My notes are all present on desktop. I don't know what to do next! Advice is greatly appreciated!

    Populus (1998) & "god games"

    Happened on this 1998 game by sheer chance and I'm really digging it! As far as I can tell it was never popular. It's a mixture of an RTS and a "god game" where one unit (your shaman) is very powerful & special (chess analogy: sort of like mixing the central role of the king & with the power of the queen).

    Strong "tribal" vibes that were popular in the '90s (think Deep Forest music, the game Riven, etc). Very nostalgic for me as I was a kid at the time. I'm playing the PSX version, looks like the PC version was even better!

    Has anyone ever heard of this "Populous" series? I'm curious to try other titles, and to try more in the "god game" genre (a genre I never even knew existed!). Any other "god games" worth checking out?

    Retro games that taste like this sounds?

    This type of music reminds me of 16-bit-era gaming - but I can't put my finger on on why!

    • Were there specific games which had music like this? (Sonic? Megaman?)
    • Or maybe this music evokes that open "sky level"-type aesthetics which sometimes featured in those games?

    Interested to hear whether this reminds anyone of specific titles or levels? Any other thoughts?

    Missing DLL, but it's in the same directory

    I'm trying to run a program in wine and getting the error 0024:err:module:import_dll Loading library jmptojava.dll (which is needed by L"C:\\Program Files\\SAS\\JMP\\10\\jmp.exe") failed (error c000007b)

    The missing jmptojava.dll file is in the same directory as the executable. Do I need to set a Windows environment variable or something so that it can find it? Any other thoughts?

    Recommended graphics settings?

    What are your recommended Minetest graphics settings? I've tried the "just turning everything on" approach, and that's fine. But it's a bit superficial. What are the knobs to turn to get a more fun graphical experience? :D

    [Solved] Why does rsync change behavior in bash script?

    I want to sync retroarch save files across devices on my local network using a bash script. Plan is to run the script as a cronjob to keep all machines synced.

    This does the trick as a one-off in the terminal: rsync -a /home/localuser/.config/retroarch/states/ remoteuser@192.168.1.12:/home/remoteuser/.config/retroarch/states/

    • Copies new save files to remote location
    • Updates any save files which were modified

    But when I put the same line in a bash script rsync's behavior changes. My bash script looks like this: #!/usr/bin/env bash rsync -a /home/localuser/.config/retroarch/states/ remoteuser@192.168.1.12:/home/remoteuser/.config/retroarch/states/ I call it with bash sync_saves.sh

    • Copies new save files to remote location
    • Updates any save files which were modified

    Strangely, rsync doesn't update modified files when run as a script. But it's not failing altogether, because it transfers new files OK. What am I missing?

    > Update: if I do the rsync in the reverse order (remote machine -> local machine) then the bash script works as expected. So my issue exists only when rsync goes local machine -> remote machine. Why would this matter?

    Update 2 (Solution): I changed the command to rsync -razu /home/localuser/.config/retroarch/states/ remoteuser@192.168.1.12:/home/remoteuser/.config/retroarch/states/, but I'm not sure that made any impact. The issue was how I was doing my testing. I was doing touch testfile.txt to change the modification date on a file & then I'd try to transfer it with the bash script & watch the modification date on the downstream machine as confirmation that it moved correctly. Problem is that rsync must be smart & doesn't transfer a file if only the modification date changes. It requires the contents to also change. Whenever I tested this way I would never see the file transfer, but when I changed my testing method to change the contents of the file instead (not just the modification timestamp) then all worked fine!

    I feel like a dummy for initially mixing testing methods & coming to the wrong conclusion about what was happening, but happy it's working now & maybe I learned a lesson!

    Custom music during gameplay (ArkOS)

    I've seen it asked (on Reddit) how to play custom background music while playing games on ArkOS. I wanted to share how I do it, in case others want to try it as well. I'm sure these instructions could be modified slightly for other Linux handhelds.

    • Gain terminal access (via SSH or directly on the device)
    • With your device connected to wifi run sudo apt install mpg123 to install the CLI-based music player
    • Transfer your desired music mp3s to a folder on the sd card
      • I use /roms2/Music/
    • Create the file start_music.sh in your ports folder which contains the line nohup mpg123 -z /<path>/<to>/<my>/<music>/<folder>/*.mp3 >/dev/null 2>&1 &
      • For me that line was nohup mpg123 -z /roms2/Music/*.mp3 >/dev/null 2>&1 & and the file was at /roms2/ports/start_music.sh
    • Create the file stop_music.sh in your ports folder which contains the line pkill mpg123
      • For me that file was at /roms2/ports/stop_music.sh
    • Log out of the terminal and restart EmulationStation

    Now start_music and stop_music options are available in the 'Ports' section of EmulationStation. Running start_music starts a shuffled playlist of everything you put in that music folder. stop_music stops the music. Of course, you'll want to turn off the native background music in whatever game your playing too :)

    EDIT: Updated the nohup line to dump outputs to the null output rather than to file (which could eventually grow to be large).

    A more relaxing way to play text-based games?

    I like text-based games (like from ifdb), but I don't like sitting at attention in front of my computer like I do all day at work. Any ideas for how to play these effectively without being on a computer?

    • I've hacked a Kindle Paperwhite & used an on-screen virtual keyboard to play these games. That worked OK, but the virtual keyboard is very imprecise and frustrating.

    • I've similarly hacked a Kindle 3 (the last model to include a physical keyboard). I hoped the physical keyboard would do the trick. Unfortunately, the key buttons are convex & very stiff - which hurt my fingertips after even short play sessions.

    Any other ideas? Or is this a fool's errand?

    Super Metroid

    Super Metroid's color palette and lanky sprite were always a turn off for me. But I'm finally giving it a chance on SNES (MSU-1 version) & I'm really enjoying it!

    Vibes are: Quake + the movie Alien + Nine Inch Nails' album The Downward Spiral. Pretty cool aesthetic after all!

    Apps won't launch from GUI?

    I've noticed that some apps sometimes don't start from the GUI. I've seen it on several computers (all running Ubuntu 22.04). That includes double-clicking an appimage icon from an explorer window, or launching an app through a launcher shortcut. But if I open them manually from a terminal window they never fail to start.

    The terminal workaround is fine... But any ideas what could be wrong with the GUI? Is there a service I can restart to try to get the functionality back?

    EDIT: I'll add that the issue is sporadic. Steam will open fine from the GUI today, but tomorrow it won't, etc. (It's not as simple as a bad path in a shortcut)

    Vocab word for "filler" items?

    In many games there are a lot of stupid filler items that you don't know what they do and they don't matter. (i.e. crafting ingredients). They are so ubiquitous across games that there ought to be a word for them. Sort of like a "MacGuffin" (except a MacGuffin moves the plot along, and these filler items don't).

    Is there a name for these filler items? If not, got any ideas?

    What's everyone playing?

    I just hit 10 hours in Earthbound on my Anbernic RG280V. I'm looking forward to trying some more SNES games once I'm finished (Super Mario World, Street Fighter Turbo II, Zelda: Link to the Past, etc.).

    Interested to hear what you all are playing? Or, what retro games are on your "to do" list?

    Programs freeze when 'save as' dialogue box would appear

    I'm seeing programs freeze when I start any operation that would open a 'save as' dialogue box. The behavior is happening with all programs and started suddenly last week.

    I've been able to trace the problem to a mounted SMB network drive that I access through a VPN. I have the mount specified in /etc/fstab. If I manually unmount (sudo umount -l /path/to/mount/) then all of these 'save as' freezes go away, and programs which appeared frozen suddenly come back to life. But if I remount (sudo mount -a) then the freezes return when I try to save anything.

    So I have a workaround solution (unmount whenever saving, remount to continue working), but I'm at a loss for how to fix this more permanently. Weird that it began all of a sudden like this, everything used to be fine. I've tried updating and that hasn't helped. Any thoughts are much appreciated!
