I saw a rant here that PeerTube creators do not receive the traffic they deserve so I got an idea!

Let's use this this thread to share great PeerTube creators! 

I'll start!

Introduction to Rust 101, a great series of videos about Rust, I'm right now on Chapter 3 and find the whole series super useful! (in English)

Heads up for #OpenBSD -current users: This is a major crank of libc and most base system libraries.

It will take time for new snapshots/packages to be built and copied out.

yasuoka@ modified src/*: Make the FILE object opaque. Move the __sFILE definition into libc/hidden/_stdio.h. All programs that refer to the internal structure of the FILE object can't be compiled from now on.
std{in,out,err} doesn't refer __sF[] now, but the hidden __sF along with __srget and __swbuf symbols are kept temporarily to make our transition easier. But those symbols will be deleted soon.
The shared library versions are bumped for libc and all the other libraries that refer to std{in,out,err}.

diff from guenther, tweak by me, tested by many

This is the same Microsoft that also says your data is only accessible to your Copilot instance, right?

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.
Show threadTommyTorty103d ago
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
Show threadTommyTorty103d ago

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.
Show threadTommyTorty103d ago
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.
Show threadTommyTorty103d ago
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.
Show threadTommyTorty103d ago
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

@TommyTorty10 im impressed neighbor, that looks like a mf of a target to chip off, so much stuff all around it and those pads look deep 😨
