If it’s sunny: go for a good walk (about 5km/3mi). Or failing that, take the cat outside and sit on the back patio for a little while. The sun exposure gives me some much needed vitamin D.

Other than that, I make sure I get some quiet time each day to recharge away from other people, virtual and otherwise.

I didn’t think it would show up in a screen recording, but I can try that. Thanks again

I like Dependent Injection, myself

It’s very quick and unpredictable. I have not noticed it across both screens at the same time, but can’t rule that out. They’re pretty thin lines and usually only one at a time, like a scan line on a TV. It just started becoming more noticeable recently so I’ll try to keep track of when it happens.

Thank you for the detailed answer, this is very informative. I should read up some more on the underflow issue. This is the first time I’ve heard that term. I’m familiar with buffer underflows, but this sounds a little more complex.

You are right, it did start happening just recently (within the last couple of weeks maybe). I forgot to mention that I am running this through a 4-port KVM. I didn’t think it relevant before because I’m not seeing any issues when using another port (my work PC), but I can’t rule it out.

It has been some time since I played with it, but I think the reason I went out-of-repo at the time was to get recent enough versions of amdgpu and rocm to run ollama. I was following some online guide and had no idea what I was doing so I probably messed something up.

It sounds like it should be safe to uninstall the out-of-repo amdgpu and rocm packages. I am not doing any local AI right now so I can probably leave it out. I do use the PC for gaming, but from what I’ve been reading it sounds like the standard drivers are good enough for that now.

Thank you everyone for your help. I didn’t expect anyone to actually reply and you guys have been awesome! I am going to swap the cables first of all since that’s an easy thing to try and see if anything changes.

Thank you for responding! I’m not sure how to find the versions, but here goes:

glxinfo reports:

Extended renderer info (GLX_MESA_query_renderer):
    Vendor: AMD (0x1002)

The exact kernel version is 6.15.9-201

I am slo seeing some amdgpu related stuff in dmesg:

amdgpu 0000:03:00.0: [drm] Registered 4 planes with drm panic
amdgpu 0000:03:00.0: [drm] REG_WAIT timeout 1us * 100 tries - dcn32_program_compbuf_size line:138

What could cause an underflow? I have two displays running: Primary is 3840x2160@60 (150% scale, HDR mode), Secondary is 2560x1440@60. Could cables be an issue?

I would also like to set if there is a solution to this. I’m on Fedora with Wayland and I have the same problem.

The best I can figure out so far is that Wayland support for rdp is limited right now and to use x11 if you really need remote desktop.

Thank you for posting this. I wondered why I was getting timeouts updating flatpaks.

In my humble opinion, being monocultural as a developer is a path to obsolescence. Be T-shaped: know your specialty really well, but also a bunch of stuff more superficially.

If you have a little hands on experience with Go on top of your Java expertise, you are imo more valuable to your employer. They may even be mid transition from Java to Go, where you would be very useful indeed.

Besides, it’s just healthy to keep learning new things.

Nothing wrong with that, and self hosting can get complex. My recommendation then is to back up the files in your Firefox profile the old fashioned way.

I think Firefox Sync already restores your profile including add-ons, if you log into Firefox. Of course you may not want that for privacy reasons. In that case, I believe there is a way to self host a sync server, but I will have to go look for the repo for it.

I legit thought this was a Wagner poster until I read the comments.

As a dev: for all their flaws, web apps are easier to distribute, portable, and have a lot of support in frameworks. They also require little infrastructure in most cases.

As a user: web apps run without installing anything, are mostly portable between my browsers of choice, and run in a sandbox to protect my computer.

Probably 90% of my needs can be served by a web app if it is well designed. If I can’t have a web app, I will look for a flatpak version and failing that I will look for it in my distro.

This. Especially if you’re a naturalized citizen. The certificate of naturalization is expensive and hard to replace. It should not be your only id. Keep it in a safe place.

If you are a permanent resident, you should already know that you must carry your card on you at all times. That is more important now then ever.

Note that you will need to mail the original certificate to the authorities to get your passport. You will get it back after a couple of weeks, but in the meantime you will have nothing, unless you paid to get a certified copy. It is a large piece of paper that cannot be folded, so it’s not practical to carry around.

While you’re at it, get your driver’s license updated with the federal id. Make sure the BMV records reflect your status. Register to vote. In other words, document your citizenship in as many ways as possible.

During my recent travels I carried a photocopy of my naturalization document plus my passport. I was not asked for it, but my reasoning was that if they took my passport I at least had something. I also had a physical notebook with important info in it, i.e., not just in my phone.

It doesn’t have to be that way, if you have a CI/CD process that prevents it.

Don’t get your hopes up. My flights were absolutely packed about 2 weeks ago.

That is famously a bad idea.

My main one is to learn shortcuts on your most used programs. Using the mouse for everything is a waste of time, but that has been said multiple times.

My second is to create scripts to do a bunch of repetitive tasks. For example, I have a script I run on my work PC after I log on to the VPN that starts my “always on” programs (like notepad++), unlocks the hosts file, etc. I have some sendto scripts for converting files with pandoc, fetching multiple git repos in one go, etc. It just speeds up things and avoids errors versus me doing them manually.

On Windows I use PowerShell and on Linux I use bash, meaning they work without additional software installed.

Yeah, I get it. I’ve had many libraries fail me in as many ways, which is why I consider it lucky to not have to implement my own. I work in .net these days, but there have been times where I had to just dig into the xml inside the xlsx and use xml tools. Those were mostly one-offs, thankfully.

Back when I did Java I had a frustrating experience with IBM’s libxml causing our app to crash after several days due to a memory leak. I didn’t have access to the production environment so it took me probably 3 weeks to find the cause and only after digging through a crash dump provided by the sysadmin. Not related, but you triggered my traumatic memory :)

I don’t know what you’re trying to do with Excel, but based on your posts, I can only wish you good luck. I’m happy to say that I have been able to outsource low level parsing to third party libraries for my needs so far. Well, except the interpreting semantic formatting part. That was on me.
