for this my wife and i use grocy. we don't really use the stock feature (which is probably the original main feature), bit is nice to do shipping lists by just clicking stuff that you already wrote and the shopping mode of the app is awesome. also the chores feature we use heavily, i just needed to tweak the ics export a bit.

I use vi to write my list and then lp that to my printer. I hate looking at my phone when I’m at the store trying to double check if I got everything.

yeah, Whatsapp really stinks in this regard. i have it in an isolated environment on my phone (called shelter), where it is frozen most of the time. you need to switch it on once every two weeks, and the bridge will tell you when. at some point I'll dump it on a phone which is just in a drawer at home, together with all the other BS apps. i tried waydroid as alternative, but somehow didn't real...

If you manage to make an account on WhatsApp and move it to waydroid, they'll ban you.

Meta's game is (meta)data collection and selling your data. They'll delete your account if they can't get all your phone's data (eg if it's an emulator then they can't uniquely identify you)

What would be the advantage?

No phone number needed. Can run directly on a non-phone server.

Also more secure and trustworthy because it's open source.

It doesn't seem so technically difficult if you can get the transit data. The phone GPS supplies your current location for the bus version, or alternatively you can just identify the most recent stop you saw. San Francisco has around 1000 city buses (I looked that up a while back) and you can put fairly precise coordinates, bus number, and route number of a bus into 4 or 5 bytes. So the complet...

Yeah, and things like arrival times could be flipped around, so time until your stop is also just the ETA of that bus to the stop anyway. Just changes to how you slice and dice the same data.

I have a lot of custom stuff, esp. regarding HomeAssistant integrations. But my favorite "stupid/not stupid if it works" solution is the following: I have an LG TV and attached Nvidia Shield. The Shield is the only input we ever use on the TV, and since its remote also can turn the TV on/off and control volume, its all we need. Which is pretty neat, only one remote. Except for image settings (i...

That's cool, and I'm glad you've made the TV take a vow of solitude!

But Signal is open source..?

Getting a phone number was relatively cheap and easy, so for a one-off implementation, Signal was an easy choice as it's what many friends and family already use.

There might be other buses ahead of the one you are on, en route to that stop. You really want the phone GPS to figure out what bus you're on, maybe showing a selection of possible bus numbers or route numbers. It would be great if you then see a route map showing your location as you move.

yeah, i understand you. i don't want to use my phone for every single thing either. in particular I'm not using it when I'm home. but in this case it's really nice for me personally, because stuff that i marked disappears from the top and often my wife and i go together, so having a synced up list is neat

The phone number part significantly degrades your privacy and security

Also the signal app depends on non free software blobs, which is a huge risk to security. Claiming that Signal is open source is disingenuous. Parts of it are open source. As a whole, it is not.

did you think about automating even the switching of the brightness? HA could do this based on the day-night cycle, dawn, etc. or it could also work with a room brightness detector

I host a bunch of small web sites, i guess the most unique is one i made recently about the "Interface Series" (also known as "Mother Horse Eyes"). It's a big old web fiction that was published (10 years ago) as a series of 100 reddit comments in unrelated threads. Just recently someone recorded an audiobook of the whole series so it motivated me to finally get this project done. Basically it's a place where you can listen to each post, and read it karaoke style, and it also links back to the original reddit comment. I've also made it so you can listen to each of the interwoven narratives as a standalone audiobook. It is hosted here : https://interfaceseries.art/ .

Other than that i am an avid collector of old content from French television like tv shows, old american series dubbed in French etc... so i have a couple of sites where i show this collection. Can't really link to it as it's not really legal but it's a lot of fun. I love the feeling of "linear streaming" as opposed to VOD : i love turning on the TV and watching whatever's showing at the moment rather than scrolling endless lists of content so most of my websites work like that. I open-sourced the tech, it's not much to look at, just a lighttpd server and some client-side logic to determine what's showing at the moment on each channel.

My ultimate goal would be to create a "French TV from the 90s" simulator where, depending on what day of the week and what time it is, you get what would probably be showing at that moment on French TV in the 90s. It's paused right now as i negociate with some guys who digitized a bazillion TV magazines from that time, and their data would allow me to get a really high def simulation.

I'm not here to fight you. I was replying with a cool thing I wrote to share baby pics to family and friends, not trying to be the most perfect hardcore op sec person on the internet.

People I know use Signal. I have never even heard of two of the three services mentioned higher up the thread.

When I wrote it I was dealing with a newborn, auditing whether Signal passes some No True Scotsman test for open source-ness was really not my priority.

Ugh, this kind of response is so off-putting. You can reply if you like but I'm probably just going to delete the whole damn comment thread because fuck this kind of purity test bullshit.

I wasn't asking for fucking feedback on my work.

I think this is a great response. I’m not sure what happened to “if you haven’t got anything nice to say, don’t say anything at all.” I absolutely agree on the purity test thing and I think the functioning solution you have created is absolutely awesome and has inspired me to try something similar. Rather than comment on the result and cool thing that was achieved, they chose to focus on some irrelevant detail because apparently it’s too hard to just say something is cool.

If you have a write up of your setup I’d love to read it. Don’t let the zealots drag you down bud.

Hah, great question. I did. And then I realized, this only works if the TV is on the moment the switch happens.

Which in the evening is actually pretty commonly the case... But never in the morning.

I am selfhosting HomeAssistant and one automation is for my ceiling lamp. As I don’t whant to touch the electrical wiring or alter it permanently, I control it via IR and imitated the signal from the original remote via the ESP32 and some IR led. This on his own does not build a full feedback loop, so the ESP does not know if the light changed after the signal got send out. I lacked the correct...

I need to do something similar. I have a Esp32S3 music player/ voice assistant connected to my old Yamaha, 90s AV receiver. It can change the volume knob via IR commands (cool integrated motor that physically turns the knob when the remote or HA changes the volume with IR).

I want to do something like put a ring magnet and an encoder on the tiny shaft or something to get position feedback to couple to HomeAssistant/musicassistant.

Some old Players got a needle that moved on a scale to show the current volume (and Channel if Radio). Do you have something like that?
This could maybe be used to encode the current volume into HA via HAL or Ultrasonic sensors.

Fascinating stuff, and a linear streaming French TV from the 90s would be awesome. For what it's worth, the only redeeming element of Amazon and other VOD services is that they do often have a ton of "live tv" channels that are just regular ol' TV, but one show over and over. Music videos or MST3K is my usual go-to.

oh right, because the TV is not available on the network when it's sleeping.

then you could save the desired brightness into some variable, and when the TV gets turned on apply the settings. I believe HA should be able to make an event when that happens. if there's a large delay, you could make a timer that forcibly refreshes the TV state every few seconds

Yeah i was also fan of apps like Mobdro which featured 24/7 feeds of TV shows or even movies by genre. That's the initial inspiration i went with.

Hmm, you mean when HA sees the TV come back? Interesting, that might work.

I's rather not do the force refresh option, because sometimes you do want different profiles. Very dark show, sometimes I want the bright setting at night. Very overcast day, sometimes the dark setting is better during the day.

Sist2 (Lightning-fast file system indexer and search tool). I'm not suggesting this is most unique use case, but noone mentioned it. I was mind blown when I became aware of it. I was looking for a way to manage my digital book and document archive for a long time. Tried various book management solution but none had full text search across whole library. Its lighting fast (like instant) you get excerpts with thumbnails and links to the files. Point it to your storage and you will gain extremely efficient way to look at your archives and references. Btw. I was already well organized and structured with my files, but going through it and searching for things I knew were there, was always a bit of a pain.

I tried it many years ago and it was nice, but I couldn't really make it fit my workflow properly.

Somewhat related, I run a linux VM with Everything search 1.5 (alpha, beta or rc, I don't remember, but it's much better than 1.4) in Wine, and that VM has most of my main storage array mounted read-only. Then I have the Everything web interface enabled, so I have a place to search my tens of millions of hoarded files instantly. Doesn't archive file content though.

Not sure it really counts. For community radio A VPS running wireguard. Four presenters connect in from home. Using Stream What You Hear to create the live MP3 stream from their mixer. Played using Zara Radio to the FM transmitter. It's pretty reliable. Same VPS hosts a Rustdesk server.

This is super cool

Because your phone gives it that info. Shelter isolated it from other apps. It doesn't prevent it from getting metadata about your device.
