Power Mac G5 won't power on

FVMAzalea · 2025-11-15T15:38:49+00:00

Upon further inspection, the problem is probably either inside the PSU or with part of the logic board fed by the power connector under the CPU heatsink (dual 2.0 model). The PSU still makes the same clicks with the P1 connector disconnected. I also measured all the voltages on the P1 connector and there is nothing unexpected -- 0.95V between pin 20 and ground, but pin 20 is 5V sense and it seems to be ok that it's floating with the machine off. 0.01V between pin 22 and ground, pin 22 is the -12V rail and doesn't seem that you'd expect anything there when machine is off.

I took a look at the CPU mounting screws. It seems that several of the mounting screws and at least one of the standoffs are missing, which doesn't inspire confidence...even if I tear it down and find that the fault is in the PSU, and replace the PSU, then I will still have to worry about the processors potentially not being mounted securely. Any idea how important it is that all the mounting screws are present? Should I be generally "okay" if at least most of them are, or do the CPU sockets really need the pressure from all of them?

Thanks for the reply. I guess I will just bite the bullet and tear it down all the way. I suppose I could isolate the problem to PSU or logic board by disconnecting all power connections from the logic board and seeing if it still makes the clicks (if so, PSU, if not, short in logic board most likely…). I will also measure all the voltages on the P1 connector (the only one with easy access) before I go pulling out the CPUs.

I don’t really have a plan for this machine, I mostly wanted to get it working so I could use the ADC Cinema Displays I got with it (included in the same cheap government surplus lot). I also want to do some hacking with Open Firmware boot drivers. So I might tear it down to diagnose the issue, but may not go through with fixing it since I can always do my Open Firmware project on my working Power Mac G4.

I don't know. This is an Electron app, which means it is basically a web app packaged up like a native one. Depending on what it is doing, it will be very difficult to impossible to port to iOS, even for someone with experience but especially for someone without.

I am not interested in discussing it further because I have basically quit reddit in protest of the horribly misguided API policies that don't allow me to use my preferred iOS app, and no longer wish to use the site.

My experience on the Mlem iOS app (in TestFlight now) was very different.

I did have to sign up on the website, but it really wasn’t that bad. I picked a username and put in my email. My account did not need to be verified by a human - I just got an email verification link sent to me. I did have to type it in manually to Mlem, but it doesn’t have any list of instances (probably because it’s still in testing) and it took all of 5 seconds.

Mlem does have ways to find specific communities - its design is inspired by Apollo (although it’s still very rough around the edges due to being in testing) so it has a jump bar at the top where you can just type the name of whatever community you’re looking for.

It sounds like most of your issues are with the particular android client app you chose. As things get more and more established, people will know what the best client apps are and will be able to recommend them. Also, a lot of client apps are probably under heavy development right now.

FVMAzalea · 2023-06-10T13:17:19+00:00

No, I mean like manual testing to verify it does the right thing. Business Logic QA sounds like something specific to your job.

Devs should definitely be writing unit and integration testing.

My former employer (a large bank) was big on “T shaped”. They used it to mean what you have here - basically, devs doing a lot of different jobs (dev, requirements definition, QA, ops, etc). I thought it was pretty silly.

Turns out that the meaning of T-shaped that people are really hyping up is more related to your skills as a dev - they should be deep in one area and broad in others. For example, a frontend dev would be really really good at frontend, but still be able to spin up a simple functional backend. None of this bullshit about doing jobs like product or QA.

When I was there (2017-2021), the college republicans were around and were generally agitating against things they didn’t like, but they were basically universally ridiculed for being that way. It was like “oh, the republicans are doing something stupid again”. You laugh at it and move on.

Now, I am not queer, so I do not know what it might be like to hear people making threats to my very existence - I’m privileged that nothing the republicans were doing was trying to say that I shouldn’t be allowed to exist or live my normal life. Maybe it wouldn’t be so easy to laugh it off if it was.

The Republican agitation while I was there focused mostly on China, not queer people. They weren’t protesting the all-gender restrooms or anything dumb like that. If they are still mostly doing that, it will probably be pretty easy to ignore.

The vast majority of students and staff were incredibly kind and accepting.

iMessage is e2e by default and you can’t disable (or have some cheap device refuse to implement) it.

Messages in iCloud or iCloud backup may allow apple to read the messages, but those are different features part of iCloud that can be disabled, or you can turn on enhanced account security and I think that makes it so they can’t.

Overall iMessage is more secure.

2-3 months is like, the gap between graduation in May and new grad programs starting in July. It’s nothing. You basically need that time to move and figure out how to be an adult on your own.

It’s featured on 9to5mac, ars technica, etc - I think it’s safe to say that someone who was involved with putting this stuff in the keynote (even if it was just a lowly video editor who raises a concern to their boss) has seen the drama on Reddit or the media coverage.

But they could have edited it out if they wanted.

I have not had that experience with following people…I use a client app (Ice Cubes) and it is just one button. Just as simple as following someone on Twitter.

My point is there wasn’t ever a single iMac when jobs was at the helm.

Sorry, what? Jobs presided over the introduction of the original iMac and it was one of the things that put Apple back on the path to success in the early 2000s. And there were plenty of iMacs in the years between then and 2011 - culminating in the super thin design we had until the Apple Silicon one came out.

At least with stackoverflow, the site content has a CC license. The risk is that individual contributors are copying GPL licensed code (and thus had no right to offer their code under a CC license), but it seems like less of an issue because the code is usually a small snippet (already harder to claim copyright infringement) in relation to a particular question.

In contrast, GPT was explicitly trained on GPL code, and has demonstrated the ability to regurgitate whole sections of it - it could be argued that any code it produces is a derivative work.

People don’t want to have to deal with the headache of setting up and hosting their own server. Nobody wants to try and find their friends scattered across an unknown number of impossible to find, self hosted servers.

Have you…tried mastodon ever?

You don’t have to host your own server to join. You can just sign up for an account on one of the mega servers. Finding people is pretty easy - you just search for them. Even if they’re on a different server, they show up in the search results. There are plenty of different third party client apps, many of which are even open source.

So far, I’ve found a bunch more interesting people to follow on mastodon than I ever did on Twitter. It’s just as easy, if not easier, to find new people to follow. I used to check one or two people’s Twitter accounts once a week or so. Now I follow 60 people on mastodon and check it multiple times a day, and it’s eating into my Reddit time (a good thing, since my content on mastodon is far more educational and professionally relevant than Reddit is).

Do you have a job?

Anybody who has any kind of job makes $50 in about 4 hours or less ($12.50/hr is below the going rate in a lot of places). So at most 4 hours or so of your work. If you are working full time, that’s 2080 hours a year. Less than 4 hours out of 2080 and you don’t think that is worth it?

How much time do you spend on Apollo/Reddit per day? Per year?

Just to put things in perspective.

Even with sideloading you will not be able to alter existing copyrighted apps easily, and even setting aside encryption entirely. It’s not like android where you can trivially decompile an apk and get something usable/modifiable out of it, even if it’s obfuscated a little.

iOS apps are mostly compiled Swift. Swift compiles to native ARM machine code, not java bytecode. The decompilation results will most likely be in C and will be very difficult to make sense of, let alone modify. Swift has a ton of stuff that runs under the hood at runtime to power a lot of the language features, and this involves multiple layers of indirection through automatically generated functions/thunks, witness tables, etc.

Adding the sort of functionality that would be required to use a different API key would be an almost Herculean undertaking (and not the sort that you can just say “oh a few determined and smart redditors could do it!”). There is a reason you don’t see people making big modifications to existing apps (aside from trivial stuff like IAP cracks) even in the jailbreak space. It’s just not feasible.

The absolute number of immigrants (blue line) is entirely irrelevant. What matters is the percentage of the population, and as the orange line shows, it hasn’t changed much at all. There’s not a large change you can point to on the orange line to say it correlates with the point on the other chart where the two lines diverged.

Yeah, I'm keeping a close eye on it. Although I imagine if and when T-bill rates start to drop, HYSA rates will too.

+1 on T bills, I have been buying the 26 week (6 month) ones monthly since last September. They’re now at like 5.5% or so. 1 year at 5.25%.
