Just got my Minimal Phone last week after two years between a LightPhone II and Sunbeam F1. Ask me anything.

So I'm new to FPGAs. I've got a project that runs fine at 100MHz on an Altera chip. I'm trying to downscale to an iCE40UL. It runs fine at 70MHz, but bumping to 100MHz and certain clocks act up/don't show up at all.

So in theory, I know there's an issue with signal buffering or routing or something, but I've never actually had to deal with this practically, and I'm struggling to find any online resources.

The iCEcube2 software comes with a floor planner that helps visualize which blocks are being used that looks like this.

Here you can see my (buffered) 100MHz clock is feeding a lot of blocks. Probably part of the issue.

I can move things around on this floor planner, but in doing so, what is my goal for optimization? Do I want to literally shorten all the traces? (as in, do the blocks in the floor planner indicate their literal locations on the chip?) or what else is the goal?

Unfortunately, I don't think I have access to any simulation tools unless there's something I'm missing, iCEcube2 is very barebones.

I’m running funkwhale in docker. This consists of a half dozen docker containers one of which is postgres.

To run a backup, funkwhale suggests shutting down all of the containers and then docker compose running pg_dump on the postgres container. Presumably this is to copy the database when nobody is accessing it.

For some reason when I do this, I get an error like:

pg_dump: error: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: No such file or directory
	Is the server running locally and accepting connections on that socket?

It would seem that postgres isn’t running. I see the same error with other commands such as psql.

If I fully boot the container and then try exec-ing the command, it works fine.

So it would seem that the run command isn’t fully booting the instance before running the command? What’s going on here?

The container is built from postgres:15-alpine

I'm moving my music library to a funkwhale instance, but I don't want to have to keep two copies of every song (one imported to Funkwhale, one on a local drive).

It looks like Funkwhale will let you download a single song at a time from your own library , but there doesn't seem to be a similar button for albums or playlists.

The files themselves are obfuscated in whatever indexing system it uses, so there's nothing to be done there.

Anyone know how this is possible?

Just got Whisper working on my local server so I can send it audio files via curl POST request and receive transcribed text.

Are there any keyboard plugins for phones that could be directed to a personal server running Whisper to replace functions like Siri/Google assistant voice transcription?

Over the week, I've been slowly moving from mdadm raid to ZFS. My process was:

• create ZFS pool on secondary server
• rsync all files over to zfs server
• Nuke mdadm array on primary and set up zpool
• ssh dataset from secondary server to primary server.

This is 15tb of data and even over gigabit, it took a day and a half to transfer. It finally finished tonight, and somehow I'm the owner and group of every single file. In addition to this generally being weird, it also broke some docker volume binds, and I generally don't want it.

It looks like the same is the case for the files on the secondary server too, so it must have happened during the initial rsync.

Fortunately, I also rsynced to some offline drives which kept ownership fine.

Anyway, I'm trying to figure out how the hell this happened. The rsync command I used was:

sudo rsync -ahu --delete --info=progress2 -e ssh /mnt/MONSTERDRIVE/ ch00f@192.168.1.65:/bluepool/monsterdrive/

At least I'm pretty sure this is what I used. I had to reverse-i-search to find it.

This is similar to the command I use when backing up to cold storage which has worked fine in the past. My understanding is that -a is shorthand for -rlptgoD where -o is "preserve owner."

So how could this have happened?

Does it matter that the secondary server doesn't have the same users as the primary server?

[SOLUTION]

From what I read online, using rsync over ssh as I did does not establish root permissions on the receiving end. So while I have the rights to modify the owners on the local side, I can only set the owners to the user I ssh'd as on the receiving side. Thus, I was the owner of every file.

The solution is two fold. First, I need to specify --rsync-path "sudo rsync" This tells the receiving side to use rsync as a super user.

Secondly, because there is no way to enter a super user password on the receiving side, I added a file to /etc/sudoers.d/ with

ch00f ALL=NOPASSWD:/usr/bin/rsync

This makes it so that the ch00f user doesn't need to enter a password when running rsync as a super user.

I don't think this is a security hole, and it got it to work.

Just noticed this a week or so ago. When I try to scroll the feed on lemmy.world, my page will halt and go even though I'm scrolling consistently on my trackpad. No other website has this problem to my knowledge.

Any ideas? It's really irritating.

I'm hosting a few services using docker. For something like an openstreetmap tileserver, I'd like it to remain on my SSD because high speed improves performance, and the directory is unlikely to grow and fill the drive.

For other services like NextCloud, speed isn't as important as storage size, so I might want it on a larger HDD raid.

I know it's trivial to move the volumes directory to wherever, but can I move some volumes to one directory and some volumes to another?

You always hear about gun sales in the US, but you never hear about what happens to the guns at the end of their lifecycle. I assume guns wear out eventually, and I assume you can't just chuck them in the garbage when they do. What happens to them?

I'm working on trying to streamline the process of ripping my blu-ray collection. The biggest bottlneck in this process has always been dealing with subtitles and converting from image-based PGS to textbased SRT. I usually use SubtitleEdit which does okay with occasional mistakes. My understanding is that it combines Tesseract with a decent library to correct errors.

I'm trying to find something that works in the command line and found pgs-to-srt. It also uses Tesseract, but it appears without the library, the results are...not good:

This is just OCR of plain text on a transparent background. How is it this bad? This is using the Tesseract "best" training data.

Edit: I’ve been playing around with ocr-to-pgs which also uses tesseract and discovered that subtitles having black outlines really messes with it. I made some improvements.
