@self_made_human, how are you getting on with the new PC?

I actually copied your specs, on the basis that you seemed like someone who knew what he was talking about, and I'm liking it very much but I need a proper monitor. You were going to get an OLED TV rather than a conventional monitor - did you? And if so, what do you think of it?

EDIT: apologies for the repost, I had the wrong Tinker Tuesday.

I'm pretty happy with it!

Even at 4k, the 5080 is incredibly powerful, and it's hard to find a game that won't hit the refresh limit of 120hz. The 9800x3d is a monster too. I can quite plausibly say that I have the world's second most powerful pc around, only beaten by people with the same CPU and a 5090.

Using an OLED TV as a monitor? It was a compromise, because I didn't have room to fit both a TV and a monitor. That being said, it was cheaper than an OLED monitor, and works fine. The only minor downside is that I use it up close and personal, which makes the effective pixel density somewhere between 1080p and 2k on a normal sized monitor. If I had the option of sitting another foot away, this wouldn't be an issue at all and even now I'm just nitpicking. The HDR and the quality of the OLED is great.

Overall, I'd say you'd be hard pressed to find a better setup, so go for it

Homies: Ride or Die and also my Tron lighting project have not had much progress this week. Instead I became consumed by

(rant follows)

a silicon degradation issue in my Intel i9-14900k.

I bought an i9-14900k about a year ago and it was fine for a few months. Then I started having random segfaults in browser processes and also when running compile jobs. I noticed that 95% of them were happening on core 4 so I disabled that and life was mostly okay again.

But not completely. Once in awhile I'd run make clean and then make and one random compilation unit would segfault. Re-running make would be fine. I tried either clang or gcc and the same thing kept happening. It would happen within like 2 seconds if I let all cores get used.

Weirdly, it wouldn't happen if I ran a more traditional CPU benchmark like stress-ng letting that run for hours and hours, and it wouldn't happen if I played an intensive FPS game since I guess those do all of their parallel tasks on the GPU. Apparently nothing stresses a CPU like big compilation jobs.

I tried dicking with BIOS settings for awhile before finally giving up and deciding to replace it with a Ryzen 9 7950x, which was supposed to be comparably powerful but doesn't have notorious silicon degradation issues like the Intel does.

Unfortunately this meant I needed to also get a new mainboard and upgrade the 128GB of RAM I have to DDR5. Also a new CPU cooler.

The Ryzen stack arrived and I rebuilt my PC with it (e.g. swapped the PSU and case and some NVMe drives) and I'm relieved to say it's been humming along beautifully.

Now I'm barking up Intel's tree to at least RMA the busted CPU so I can look to either build another PC with it (at this point I just need a PSU and case) and hand it down to my kid, or maybe I should try to sell it as a complete system and recover some of my losses. I expect if I try selling it all I'll about $800 on this experiment due to the mainboard and RAM and cooler being used.

Why didn't I just RMA the Intel CPU with the cross-shipping option where they send you the new CPU first and then you can return the broken one? Because I just was so done with Intel. I can understand a CPU not working from day one, but something about it degrading with time and this being such a widespread issue is really crazy-making.

Oh yeah while I was trying to make this decision yet another Intel CPU security issue was discovered https://comsec.ethz.ch/research/microarch/branch-privilege-injection/

Basically sealed it for me. How far Intel has fallen.

In the meantime I decided to switch my diff tool to difftastic, since it understands the ASTs of 30 different programming languages (thanks to tree-sitter) and it can show you AST related diffs that are better at displaying what meaningfully changed rather than mere line/word diffs. Should reap insane efficiency gains.

I want so badly to believe in Intel, but it just keeps getting worse. Sorry you got burned.

I'm still happy as a clam with my 5800X3D and an RTX 4070S to go with it. But I'm throwing $50 a month into a "New Computer" fund whenever I decide it's finally time to upgrade. Who knows when that'll be. Since switching to Linux Mint things generally seem much snappier. I know it boots it like 10 seconds versus the 60+ Windows 10 takes these days. Really makes you think how much of that feeling of "Ugh, my computer has gotten slow" is just Windows cruft. Linux Mint feels as fast as the day I first built this thing (when it was a Ryzen 3700X and an RTX 2070S) and was blown away at how much faster a NVMe drive was to boot from.

Stupid planned obsolescence.

Thanks.

I think Intel was desperate to have the fastest single thread performance, even if it means losing at energy efficiency and risking physically killing the chip. Worse, despite these sacrifices it can't even sustain the top speed for very long.

Re: Windows, I don't fucking get why Microsoft doesn't worry about performance more. Even if you aggressively tune Windows and disable a bunch of crap any default Linux distro feels more responsive.

What made you select Mint?

Re: Windows, I don't fucking get why Microsoft doesn't worry about performance more.

Honestly, I'm pretty sure Microsoft just doesn't care about Windows anymore, period. Their money-maker is O365 and Azure subscriptions, which they will gladly sell you on any platform of your choice.

I think they've quietly given up on Windows in general shortly after giving up on Windows Phone. After admitting they were not going to own pocket computing, they must have understood that their monopolistic hold on the software ecosystem was inevitably going to get shattered. Without owning the software market, they have to compete on the quality of the operating system, and developing a state-of-the-art operating system costs too much, and it's too hard to extract money from it compared to cloud services.

Add to that their multiple failures at taking control of PC game distribution which cemented, even before the Steam Deck and SteamOS, that gamers were going to follow Valve wherever they go, not Microsoft.

The fact that I'm a Linux newb and it was supposed to be the most user friendly. I don't think I see myself distro hopping either, I just want something that works, and it does. But who knows, maybe I'll find myself with more time than sense and going down rabbit holes.

Oh. There probably isn't much substantive difference between desktop distros if you do a mainstream one. Mint might come with nicer defaults out of the box and that's cool but if you can flip over to a Mac or Chromebook without much trouble than a random distro like Ubuntu probably wouldn't be any more wack.

Yeah, Ubuntu was going to be my first choice because it seems so ubiquitous and stuff like Steam claims to only support Ubuntu. But a friend of me talked me out of it because Ubuntu began gathering telemetry or something? And a lot of the places I used to see evangelizing Ubuntu shifted to Mint?

I donno man. I'm an outsider looking in.

Oh. There's some. Telemetry for a Linux distro will be pretty weaksauce compared to the rest of the world because of how fickle Linux users are.

But yeah no harm in Mint if you want the full anti-corpo experience.

I also know geeks who have limited Linux experience, but know they don’t want Ubuntu because of the telemetry scandal… which was, what, like 12 years ago or something, and completely irrelevant to modern Ubuntu?

The movement towards desktop Linux among techies has been driven largely by Microsoft telemetry in Windows, so it’s not entirely surprising to me that “avoid telemetry at all costs” would be an essential driver for them, even if people don’t really understand what the scandal was about and what modern Ubuntu is like. (Which, to be fair, has its own details that alienate a lot of greybeards.)

The big one was embedded amazon web search in the start-menu equivalent from 2013-2016; Cortana is obnoxious enough that I don't think anyone wants a Linux version. Not an issue in modern versions. Ubuntu OS itself now is just limited to an on-install and on-wakeup 'here's my system specs' sorta stuff, which I agree basically rounds to not mattering, but I will caveat that the Snap Store is more aggressive (sending on-program-start info, at minimum) that it may have additional concerns.

The good news is that the Snap Store is so badly maintained and especially filtered that you should basically never use it -- Snaps are slow to launch, they're often out-of-date (even by downstream standards), they're bloated even compared to flatpak, and Ubuntu has been extremely willing to let outright obvious malware into the store. The downside is that Canonical really wants everything moved to Snap, and unless you uninstall snapd you can get surprised to find things like your web browser or IDE can 'upgrade' to their Snap version.

((This is not an advocacy of flatpak. Just damning Snap with faint praise.))

That said, you can remove Snap, and I think it stays gone, so still better than Windows. Just a lot of footgun opportunity compared to something like Mint.

More comments

Charity drive for @AlexanderTurok ! Upvote all his comments!

Through a cruel twist of fate (or the r.drama code copypaste fairy), this innocent member of our community is constantly being censored! Only you can solve this terrible software issue forever.

Do you feel that posting a flag isn’t enough philanthropic effort anymore?

Spare an upvote or two for a poor silenced soul, every bit helps!

Tired of celebrities always helping you, but YOU never being allowed to help THEM?

That’s right, he’s a VIP, world famous in the fourth degree, karlin just name-dropped him. Go to his user page now, and give an arrow to a star!

Unless you're coding a way to whitelist him, I don't feel like this is an appropriate thread for this post.

How would a no-nonsense engineer such as yourself tinker with this problem?

Because it's very tedious and time-consuming to go through his page, click on the link, and then upvote (you can't upvote from the user page).

One thing that's mildly more effective is sorting by new, so you land on a thread, and there's a good chance there are more comments of his upthread, and so you've saved a pageload or two, which feels great. It might possibly be related to what you programmers call The Big O.

Another idea I have is simply to ask him to make 20+ one-letter comments on some dead thread so I can really cut down on the time spent per upvote.

what you programmers call The Big O.

Somewhere in a coding boot camp, the drill sergeant is calling for a trainee to "Show me your Big O Face!" /s

argh

I tried to sprinkle some tinker flavour out of respect for the dignity of this thread. But really I feel all the non-culture war megathreads should be merged.

Man, where was I? Making the stretchers for my chairs over again I think?

I had a pretty productive week then I guess. Made the stretchers to the proper length this time. Doing the tenons at an angle was new for me. Starts off the same as any others, but then I had to hand cut the last bits. Fit perfect in the final product this time. The final parts I had to make were the seat bottoms. I got the template done and then routed out the panels I'd glue up last month to shape. Looks fantastic in place. Unfortunately the panels weren't wide enough to give the seats the kind of flourish I would have liked, but they do taper slightly towards the back and round slightly around the front legs.

I decided to tempt fate some, and give the chairs a bit more of a backwards tilt, just 3/4" off the back legs. Adds roughly 2.5 degrees to the tilt of the chair and IMHO made it way more comfortable. I wish this had been built into my template, but I wasn't using CAD software or anything, so I had to figure it out after I had a physical object in my hands. Sadly the best way to cut them was by hand because they were curved and I didn't have a good reference plane to throw it on my tablesaw or miter saw. Also I felt like it would go wrong slower with a handsaw. I think I cut them mostly even. Nothing the felt pads I'm putting on the bottom, or a hand plane and a shooting board worst case, can't fix.

I'm in the end stages of this project. Some light edge profiling, filling in knots and voids with sawdust and glue, sanding, finishing and then final assembly. Probably still going to take me a few more weeks to get through all that. I've decided to finish the parts separately and then assemble them. I don't think having a little shellac around the mortises will weaken them too badly. After all the slot and the tenon are doing most of the work, not the end grain of the shoulder being glued to the work piece. Plus I've just had better luck get a consistent finish when I do smaller parts without inside corners, and then assemble it

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.
