Most places I've lived weren't this nice.

Crunch

there are already usb-powered devices that redirect/mirror a modern wifi connection to ethernet in order to use older computers on modern wifi

why can't we have those devices also strip HTTPS

i might have to do some researching and prototyping

I think any openwrt supported device could do it if it has enough ram to run a transparent proxy. Depends on how strict your usb-powered requirement is.

Trust me, this is a terrible idea right now.

I found a discussion about it at https://socialhub.activitypub.rocks/t/switching-ap-server-software-on-the-same-domain/4508. It looks like Masto (Activitypub?) uses the uri as an identifier. Replacing the software will make all those objects invalid, so trying to tell others that you've moved would be challenging.

As someone mentioned, using say sponge@really.goodass.dog for a new instance would work, you'd just want to leave the old instance up until most of your followers have moved over. And the post history, unless there's a way to migrate.

Switching AP server software on the same domain

Hi all, I’m considering setting up my own single-user (or possibly family and friends) instance of a lightweight AP server such as GotoSocial or Mitra (other recommendations welcome). However, I’d like to be able to switch server software in the future if I find something I like better. I’ve read (in the GtS docs) that this can cause major federation problems. I wonder if it would be possible to switch if my server is hosted on a subdomain (social.example.com, etc), even if the handles use t...

if mastodon is about user freedom, then why am i trapped?

i've been running a server on my domain since 2018, and i'm tired of keeping up with the updates. i'd love to try a simpler piece of server software to make maintenance easier, so i took a look at gotosocial, and at the top of their guide is this:

"It's not supported across the Fediverse to switch between implementations on the same domain"

...excuse me? so now this domain is permanently tainted?

so what are my options?

- transfer my account to some other site. be part of all the drama and defederating and dealing with mastodon HOAs. lose my fun domain account domain name. don't bring along any of my data/pictures/posts, which frankly is the thing i care about more than my followers/following. i can download my data but who gives a shit i can do that on twitter.

- keep running tootsuite until the end of time, and having to computer janitor it to not get my shit hacked. i don't even want to host a web ui, i only use external clients, so i'm spending god knows how much resources on my vps just to run this stack i'm not using.

- buy/use a different domain, setup a new server there, hope i picked a good one that i won't regret using! transfer my following/followers, and lose all my post history

- delete everything and stop using this piece of shit thing.

the people who came up with this design are fucking stupid. not only is my data trapped inside tootsuite in any meaningful way, but my domain is also now permanently locked to this install.

I spent some time removing solder with copper wick until I got bored of it. Next thing is Im gonna try to retin the pads with normal 60/40 solder for science, since I dont have a reballing kit, and I want to learn how bad this can get. The plan is to just smother some solder on with a pencil iron and then to try to reattach the chip and see if I learn anything in the process.

As many of u probably could have predicted, trying to slather solder onto stuff with a pencil iron just removed the existing solder and left very little behind on the pads. I guess Ive learned to add leaded solder if I want to quickly remove lead-free solder from a bga.

Attempted to reattach the chip, and I was surprised at how suddenly it started moving really freely when all the solder melted. The board wasn't perfectly level, so it didn't wind up super straight, but Im glad I learned that a very level board will be important. Now that it's cool, it feels very strongly attached, so I guess that at least some of the solder bonded. Im gonna pull it off and put it back again to test what Ive learned.

Pulled it off faster and easier this time. I maxxed out the heatgun at 480C. It looks like not all of the solder joints melted when I reattached it it, because I recognize a few fatter globs, and they seem to have the same shapes as before. The SMD components on the other side are all still present.

This time, Ive put a tiny hotplate under the board to see how it affects things. It's directly touching the smd parts but is way too cold to melt their solder

The board was more level, and the hot plate definitely made a difference. It was much easier. I didn't see the chip move at all when the solder melted but figured it out by poking it with the tweezers and feeling that super smooth and light movement from it. The SMD parts directly touching the hotplate visually look fine. Most of them are ceramic caps. I poked them with an ohmmeter, and there doesn't seem to be any obvious shorts.

The bga looks a little crooked by eye, but upon reviewing photos from before I started working on this thing, it's crooked in exactly the same way it was from the factory, so maybe that's just a silkscreen thing. I feel a lot more confident for when I go for the emmc on my Chromebook now. The emmc will be a smaller chip with fewer pads, so it should be easier.

I pulled the chip off one more time, and it looks like all the joints melted. I also decided to take off one of the mosfets, since the vrm portion of the board has some power planes that are meant to draw heat away from the cpu. It came off easily and promptly disappeared into outer space.

To reiterate my lessons for my own memory, the hotplate was much more useful than expected even though it doesn't make great contact. It seems possible to just put some solder on a chip and a board without a reballing kit, but idk if I'd bet on it to make contact on all of the pads. Adding leaded solder with a pencil iron honestly helps to remove old lead-free solder. Keeping the board really level also makes things a whole lot easier. Maxxing out the heatgun at 480C seems to be the way to go.

At the time I bought the soldering station, there weren't other heatguns available for the same temperature in the same price range, but I wonder if that's changed, or if there really is a lot different with more expensive units. Im sure if paid $100 more, I could have gotten something better, but it doesn't seem worth it for something I just dont use that much. I use the pencil iron a lot, and it's been great! I still would like some more heat from the heatgun. Ideally, I think I'd like to be able to damage the board with the heatgun as easily as I can with the iron.

I've been thinking, the inlet grommet in the chassis is really narrow, and I'm sure the flow meter also restricts flow a little. Since all the plumbing is just rubber tubes, I might just reroute things and see if I get more airflow. I haven't used the "fume extractor" much, because it isn't very effective, but maybe I can change that and improve the heatgun as well. I think tomorrow, I might try to remove the flow meter from the plumbing and maybe drill the grommet a little wider if it has enough meat to get away with that. I think I've got little fan blades on a dc motor from some kids' electricity educational kid from decades ago which would be great for measuring actual airspeed from the end of the heatgun. The heatgun doubles as the output of the fume extractor, so I can just turn on the fume extractor to move air without melting the fan blades.

@TommyTorty10 that's some good practice! I recently looked into upgrading the soldered RAM in a Mac Mini and realized from some videos that this stuff is way outside my skill set... Maybe I should find some old boards like this for practice too 🤔

@TommyTorty10 oooh super interested in how this goes, ive only used these freaky little things on very small boards before
