Fellow PC builders, here's a fun one for you.

I took some "old" and no-longer-used PC parts and built my sister-in-law a gaming PC for her and her stepdaughter to use. It was a Christmas gift so the stepdaughter could play the Sims.

She has called me three times to tell me it's completely frozen - like hard locked, dead freeze, screen is displaying the last frame it was on but you can't interact with the PC in any way until you reset it with the power button.

She let it sit for an hour before she gave up. Two times this happened while stepdaughter was playing the Sims 4 and once it happened while my brother-in-law was watching YouTube videos.

Obviously, I went through the usual things you'd think in this situation and I had her bring the PC over so I could do some digging. Fully expecting to find a hardware issue, I tried the following:

1. I ran the Sims while also watching multiple YouTube videos in the background. Couldn't replicate the issue after about two hours.

2. I obviously checked the temperatures while gaming and YouTubing, checked the usual performance metrics and everything was great.

3. Ran OTTC stress tests - all of them. Under heavy loads, this thing was doing fine. Even at 100% utilization, the memory, graphics card, and cpu were fine. Did a power test too, fine. Did a "combined" stress test and all was fine.

4. Ran mem86, no issues with the memory, no bad sectors or errors.

5. Played Skyrim on ultra for several hours. This was a really fun way to troubleshoot.

6. Checked the event log from the day she had freezes. I can see where the event happened because leading up to the unexpected "power off" event, there were a ton of events related to various processes timing out. Seems like it was unable to connect with services and run certain background processes while it was frozen? I didn't see anything that really stood out to me as being a possible cause except...

7. in the event viewer, there were a few events related to Microsoft family safety. I set this up at the request of SIL so stepdaughter wouldn't get into anything she shouldn't. In the Event Viewer, it seems like maybe it wasn't verifying something correctly or didn't have permissions it needed? Upon Googling, I found some other folks with this error but I couldn't find anything about whether it caused freezing or not. Seems like one of the many events that just gives a warning but doesn't have any effect. One guy who had this issue had his computer freeze but disabling the family safety entirely did nothing. People in the comments thought it probably wasn't related. I also found another event that Google wasn't very helpful with. Might have been related to sound card but my sound card drivers are up to date and again, I have not been able to replicate the issue even when gaming and watching videos, so I don't know if it's related.

8. I ran the Windows System Files Checker and found no issues related to my Windows install.

I can't figure out why this would be happening only at her house. She says it froze after one hour of use every time. This brings me to the title of this post. My SIL moved into a really old house with sketchy wiring. My FIL told her the wiring is so bad that she needs to get it fixed immediately or risk a fire, so she's working on that. This house has a butler stairway, asbestos, and plaster/lathe walls if that tells you what we're dealing with here. This is the ONLY thing I can think of that would possibly be different between the two setups and maybe explain the freezing, but it just seems so unlikely to me that this is the cause.

Help?

There are a lot of awesome open source projects that I'd love to donate to, however, I can't afford to donate to all of them.

It would be great if there was something like a charity fund (eg. GiveWell), but for FOSS. So a lot of people donate to it, and it distributes all collected money between some curated projects (most influential/important/promising/underfunded/etc.).

Do you know if something like this already exists? if not, could it potentially be a good idea to do? It seems like the idea of donating to open-source is currently more prominent in the community due to the xz backdoor thing.

I have a guitar multi effects that has a headphone out with 47Ω

I want a budget somewhat neutral headphone to use with it and I am getting confused with the answers I found so far.

The AKG K240 mk2 (55Ω) seems to be a popular choice with people who own another multi effects (HX Stomp) with a different impedance (I think it's 12Ω).

This headphone is within my budget, but it seems too close to the 47 output of my multifx.

Will I have a problem with this?

I read somewhere that the headphone impedance should be much bigger than the output impedance, but another text I read somewhere explained that they should match closely.

I'm really confused about this.

I'm taking some time to set up a mastodon account, and am currently confused about how following other federated accounts is supposed to work.

Let's use https://lemmy.world/c/comicstrips as an example. I go to that link and I see posts from other federated sites, as well as posts made directly on lemmy.world (I presume). I can also view all posts from that community in r.nf as well (https://r.nf/c/comicstrips@lemmy.world). I see all the same posts from the lemmy link.

What I don't understand is why, when I follow @comicstrips@lemmy.world on mastodon I only ever am shown replies and boosts from the account. I don't see the original image post, which I was expecting.

What am I missing? For what it's worth I'm using Phanpy to interact with mastodon, but am experiencing the same behavior on mastodon.social as well.

I have managed to install and configure something called NextDNS on both of my devices and most browsers, even though the documentation seems to be made with more tech-savvy people in mind. So far so good. I turned on all the available blocklists, but a lot of strange looking (to me) traffic is still getting through. I'm assuming some of it is benign, but how do I evaluate which addresses I should block or not? I'll list some examples below.

init.ess.apple.com
init-p01md.apple.com
bag.itunes.apple.com
gsp-ssl.ls.apple.com
gspe35-ssl.ls.apple.com
pki-goog.l.google.com
For these, the service offers the following information: 'Provides advertising or advertising-related services such as data collection, behavioral analysis or retargeting.' Sounds like something I wouldn't want to enable. When it comes to the iTunes one, I don't use iTunes and don't even have it installed (don't ask how I managed to get rid of it - it took several days worth of trial and error..). One of these, pki-goog.l.google.com is listed as 'dangerously prevalent (tracks 21.23% of web traffic)'.

Then again, the same general description is sometimes given to addresses that seem legit, such as:
time.apple.com
weather-data.apple.com

Some are indecipherable to me and don't come with any sort of description:
fp2e7a.wpc.phicdn.net
init.ess.g.aaplimg.com
get-bx.g.aaplimg.com
ocsp2.g.aaplimg.com
ocsp.pki.goog

Some descriptions are kind of vague:
a2047.dscapi9.akamai.net
apis.apple.map.fastly.net
'Content delivery network that delivers resources for different site utilities and usually for many different customers.'

Some seem to be doing tasks that are definitely wanted:
ocsp.digicert.com
'Digicert Trust Seal - Includes tag managers, privacy notices, and technologies that are critical to the functionality of a website.'

Then there's an Amazon Web Service, go-updater-1830831421.us-west-2.elb.amazonaws.com, listed as very prevalent (tracks 5.5% of web traffic) that has been contacting my phone even though I haven't done any shopping or product related searches. What is this and should I block it?

And so on and so on. Is there any logic to these that I can follow? I tried google searching some to no avail.
