I generally let my server do its thing, but I run into an issue consistently when I install system updates and then reboot: Some docker containers come online, while others need to be started manually. All containers were running before the system shut down.

• My containers are managed with docker compose.
• Their compose files have restart: always
• It's not always the same containers that fail to come online
• Some of them depend on an NFS mount point being ready on the host, but not all

Host is running Ubuntu Noble

Most of these containers were migrated from my previous server, and this issue never manifested.

I wonder if anyone has ideas for what to look for?

SOLVED

The issue was that docker was starting before my NFS mount point was ready, and the containers which depended on it were crashing.

Symptoms: journalctl -b0 -u docker showed the following log lines (-b0 means to limit logs to the most recent boot):

level=error msg="failed to start container" container=fe98f37d1bc3debb204a52eddd0c9448e8f0562aea533c5dc80d7abbbb969ea3 error="error while creating mount source path '/mnt/nas/REDACTED': mkdir /mnt/nas/REDACTED: operation not permitted"
...
level=warning msg="ShouldRestart failed, container will not be restarted" container=fe98f37d1bc3debb204a52eddd0c9448e8f0562aea533c5dc80d7abbbb969ea3 daemonShuttingDown=true error="restart canceled" execDuration=5m8.349967675s exitStatus="{0 2024-10-29 00:07:32.878574627 +0000 UTC}" hasBeenManuallyStopped=false restartCount=0

I had previously set my mount directory to be un-writable if the NFS were not ready, so this lined up with my expectations.

I couldn't remember how systemd names mount points, but the following command helped me find it: systemctl list-units -t mount | grep /mnt/nas

It gave me mnt-nas.mount as the name of the mount unit, so then I just added it to the After= and Requires= lines in my /etc/systemd/system/docker.service file:

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target docker.socket firewalld.service containerd.service time-set.target mnt-nas.mount
Wants=network-online.target containerd.service
Requires=docker.socket mnt-nas.mount

I recently got a nice deal on a stereo microscope, and leapt at the chance. I've had a few projects in mind that would entail SMD soldering, and now all I need is a proper soldering station.

My current iron is pretty basic, but gets the job done for splicing wires and DIP work. Now I want something with temp control and a good supply of tips.

It seems like hobbyists are all talking about affordable Chinese T12 stations from brands like KSGER and Quecoo. There are just so many different models, it's hard to understand the features and differences. It also seems like there's a lot of "Reddit folk knowledge" where people just keep repeating what others have said. Eg: People say that some KSGER stations have no case grounding, but nobody says which models do or don't have the issue. All of them? Then people talk about the microcontrollers STM vs STC, but nobody says why it matters.

In our house, we generally go for variety in our coffee beans. That means when we are finishing one bag, we're going to open a different bag with totally different beans inside.

What do you do if there aren't enough old beans to make a full serving of coffee?

It may be heresey, but I mix the final old beans with a few beans from the new bag and call it my "bonus blend".

What cool stuff is going on with IP over ham radio? I want to build simple services accessible to other hams in my area, and would love to learn about what's out there.

• New Packet Radio: This looks pretty cool, although until the FCC makes a decision on updated VHF/UHF bandwidth and symbol rate restrictions, I'll hold off on buying any dedicated hardware

• Broadband HamNet: I'm not sure if there's any existing network in my area. Since it's 802.11 with yagis and amplifiers, I feel like you'd need a good density of local users for anything cool to develop.

• AX.25 with TCP/IP: I might play around with this. It doesn't require equipment except a UHF/VHF radio, antenna, and a computer, so it might be easier to convince others to try it too. Obviously you're very limited in bitrate, but it would be fun to set up a gohper hole or a BBS.

Are there other technologies or projects worth looking into? Even though I'm not personally interested in buying new equipment for it, I'd still like to hear what's out there.

I work in a basement office. There is a below-grade egress window, with a 3-4ft ladder and a large plexiglass dome that you can push out of the way.

I noticed a terrible smell when I opened my window the other day, and it was because of a dead mouse that presumably couldn't get out of the recess. On inspection, I found the remains of several more dead rodents there, so this has been a problem in the past too.

Any ideas on how to prevent this? I both feel bad for the dead animals and am disgusted by the smell when they decay. The plexiglass dome has chicken wire for airflow, so I can't necessarily block those off. Maybe there's some method to repell them, or help them escape?

Just moving in to our first home, and I'm very excited to have the freedom to set up a permanent HF antenna.

I'll probably build a sort of fan dipole and run it along the side of our property. That's the only place long enough to fit. However, the power lines for the neighborhood run over part of our backyard. I'm not worried about my dipole being too close to high voltage power (it won't be) but I wonder if the AC frequency can cause interference on certain bands?

I'm really intrigued by digital modes. Stuff like JS8Call seems really cool, and I want to get into it.

I don't have any HF equipment. SSB isn't very interesting to me, so I was thinking of getting a digital-only transceiver and saving some money. I think it would be cool to take a small QRP box with a laptop or raspi, and do digital mode Pota with it.

I've seen the QDX which looks exactly like what I want and seems to get good reviews. Any others that I should be aware of?

I like coffee. I like Star Trek.

I've had a mild interest in the raktajino, a Klingon coffee drink commonly consumed in DS9. I've looked up a few fan theories and fan recipes. I haven't seen any references to a canonical recipe, so I get that there's a bit of fun and personal preference involved.

The only thing I don't understand is why raktajino is commonly claimed to be made with liquor. On the one hand, I understand why Klingons might want a stiff additive to their caffeine. However, the context in which characters on DS9 drink it does not suggest the presence of intoxicants. I recall at least a few occasions in which bridge officers, while on duty, drink a raktajino. Surely even synthol is not OK when you're on shift for Starfleet.

We're 3 game sessions deep into a Vampire the Masquerade chronicle. I've just heard from one of my players that they feel like they've put a bit too much of themselves into their character, and they're starting to get uncomfortable with it. As such, they'd like to roll up a new char sheet and bring their current character out of the game. We've talked a little bit about whether they want their character to die, or to permanently leave the party, and that's still up in the air.

This is my first time as GM, and I'd like a few pointers on how to work with this. From an "off the table" perspective, I've already had a conversation with this player about what their needs are. I'm confident that the overall game is still fun for them, and that this isn't about any player-player dynamics.

From a narrative perspective, I'd love to hear how others have dealt with this before. In the past 3 sessions, I haven't had the chance to bring out the kind of enemies who could kill a PC outright (bloodthirsty elders, second inquisition deathsquads, conniving underlings). I don't want the player to have to go through several more sessions with a character they dislike just because it would have more punch further down the line.

I'm just getting into ham (my technician exam is tomorrow night), and I'm looking for ideas on starter kit.

For now, my interest is in making contact with a friend who lives ~10 miles away, as well as other amateurs in the county (there's a repeater ~2 miles away). This friend needs to reapply for his license, but he has a mobile 2m/70cm transceiver from his old call sign. Eventually, we'd like to get into digital communication between our houses.

Even further down the line, I think long distance HF sounds cool, but that looks like a money pit I'm not quite ready to dig just yet.

I don't want to set up any crazy antennas just yet, as partner and I are house hunting. This also means we could end up more like 15 miles from my friend, depending on what we find.

I was wondering if anyone here could suggest beginner's equipment for my goals. I'm ok to spend a bit more on systems that are still useful if my interest in ham expands beyond these initial requirements.

I won't say I can't draw (anyone can put a pencil on paper), but I will say I have no practiced skills.

I've never done character art before, but I want to for this game. What alternative ways do you have to represent your character visually?

I've considered AI generators, but I don't want to spend money and time tuning the prompt to match what I want vs what the AI thinks I want.

I've also thought about a collage to represent different aspects of my character, then mashing some elements together with GIMP.
