The popular music is garbage and Garbage is forgotten.

About that:

I realized something many years ago: people of a certain age always tend to think music from their time was better. But they all fail to see that whatever music from their generation is still around is the good shit from that time. For example, this still plays on the radio but this thankfully doesn't.

Whatever young people listen to now is everything: the good and the bad, and mostly the bad. Their shit hasn't had time to decant yet.

So yeah, to an older listener, today's music is mostly shit, because it is - just like the music from their past was mostly shit when their past was today 🙂

you can learn the lingo it really doesn’t change that much from generation to generation

That's not the problem: if I talked to a kid with that kid's generation's talk, they would look at me with an air of pity. Just like I looked at adults trying to be hip when I was a kid. Older folks who don't stay in their place aren't well received, and I'm one of them now, so I abstain.

When I don't understand what young people say. Worse: when they don't understand what I say.

Well yeah, I look at All too, to make sure I'm not missing out on something interesting. But I must do that every month or so.

That escalated quickly

That's too much credit to the poster.

I'd say it went down the sewer quickly, rather.

Ah right okay.

I only look at the ones I subscribed to myself. Different approach I guess.

Forgive me if I'm a bit of a thicky, but why is there a need to block communities? Doesn't simply ignoring them work?

 

Exoneo makes 2 prosthetic feet: the Mahi for moderate to high activity levels and the Upya for low activity.

Both have a spring block under the heel and spring-loaded "metatarsals", which helps push-off when walking:

You can even assemble and size them yourself:

More interestingly, it seems the company has a lot of customers in developing countries, meaning there's a very good chance those feet are affordable. Sadly, I couldn't find prices and I didn't want to request a quote for nothing.

I did find an independent review of the Upya foot (in French here, automagic translation here, accompanying video here), so at least it's not like all the information I could find comes solely from the manufacturer.

The reviewer confirms that the foot was competitively priced: although he doesn't disclose how much he paid for his foot, he does say it's "a prowess considering the price at which it's sold". That bodes well.

Damn... Now I want to see the entire Akira redone like that.

the blue gel was phased out decade(s) ago

But I can still buy it?

Good advice though. That's why I come to Lemmy: I learn useful stuff all the time.

not using it with a food microwave

The microwave sits in the workshop and is not for cooking food. It's strictly to do nasty stuff with materials I work with.

I wasn't aware. I'll look into that. Thanks!

I trust Google a LOT less than I trust Apple

I have zero trust in both. So if I have to choose a dystopian surveillance device, even a stock one, I'll choose the one that lets me sideload apps anyday, even if the experience is less polished.

And of course, I run a deGoogled OS so the point is moot. I use it for work stuff and I have no issues. I feel no need for a regular Google or Apple piece of spyware.

What you call a prison, I call a system where I don’t have to fuck around to make shit work. Everything Just Works.

So, just like I said, you're happy in your prison. It's cool, to each his own 🙂 It wasn't a value judgment. Me, I'd rather cut one of my testicles off than give a cent to Apple - or Google too for that matter - or let either decide what I can or cannot run on MY device.

iOS is more fit for my purpose than Android.

As long as it does what you want, then it's fine.

 

So I've been exploring the fabulous word of additive manufacturing for a few months now with my company's 3D printer - a Prusa Mk4 - that we employees are welcome to use for our own personal use when it's not busy printing tooling for work of course.

I've gotten really good at squeezing the most performance out of that thing: some of the functional parts I made with it at scales that are pushing the boundaries of what regular PLA out of a 0.4-mm nozzle can be coaxed into becoming, I'm properly proud of.

And I'm having a lot of fun finding ways to overcome the limitations of FDM. I don't really want a more precise printer: half the fun is witnessing a part that shouldn't exist come out of a printer that doesn't really have any right to be this good. Pushing the envelope... It's the spirit of hacking in the world of 3D printing and I love it!

But now I'm wanting a printer of my own. The company's printer is fine and all but when it's doing work-related things, I can't use it. And I have to wait to go back to work the next day to print something I modeled the evening before.

So I'm on the market for a good fast FDM printer that can print prints with different filaments at the same time, because I'd like to experiment with stretchy materials but keep using rigid and cheap materials for the supports, and also to play with colors. And I think I want a core XY printer because I've run into problems with big heavy prints with the company's bed slinger.

And finally, something that's really important for me: I want something as open source as possible that doesn't phone home, and ideally not made in China.

Money is not tight. The kids are out of the house and I have a well-paid job. I set my budget to 5k - dollars or euros.

So with those requirements in mind, from what I read, the best option for me is to stick with Prusa: it's more expensive for what it does but it's not sketchy Chinese spyware. Also, I know the brand already and I've been nothing but happy with it so far.

And in the Prusa line, I'm tempted by the XL with an the bells and whistles - namely 5 heads and an enclosure.

But here's the thing: I hear this machine has problems. Is it true? Would you have a better suggestion? Possibly another brand that I should consider?

 

Maybe there's something I don't understand here. I'd love it if someone told me how to do the following.

Let's say I have some really complex shape in a sketch left of the Y axis: it takes me forever to get it just right. Then I need to mirror it on the right side of the Y axis and connect the two halves.

In SolidWorks, it's trivial: mirror the stuff, done. If you change the master shape on the left, the change is reflected on the right.

In FreeCAD, the best you can do is make a mirror copy of the left-hand side elements - which also makes copies of the constraints which are completely independent from the original constraints on the left-hand side - delete the stupid new right-hand side constraints and slowly, painfully constrain the right-hand side copies to the original left-hand side elements, trying to dodge the dreaded orange over-constraints all the time. It's long, it's painful, and the end-result is usually so fragile that if you change anything significant on the left-hand side, the sketch turns orange and then it's back to hunting broken constraints again.

Surely it can't be that painful. Am I missing something obvious?

 

I had new progressive lenses made, but the old ones are still fine and don’t have a scratch. They’re just a bit weak at near distance, but otherwise perfectly serviceable.

So I made new frames for them because I don’t like to throw away things that work.

All assembled, the frames weigh 3.5 grams, and 14 grams with the lenses mounted.

This was printed with a Prusa Mk4 and regular PLA at 0.15 mm layer height. The hinges use simple 10x1 pins - and I worked my magic to print the holes horizontally to the final dimension with interference fit, so no reaming or drilling is necessary. These glasses are straight out of the printer with zero rework.

I think they look pretty good as they are. If anybody notices they’re 3D-printed, I’ll say I’m gunning for that particular style 🙂

The front of the frames prints in 11 minutes and both temples in 12 minutes. I could break and make a new pair every day for the rest of my life and it would still be faster and cheaper than going to Specsavers only once.

 

This did not make it here.

It's that time of the year again.

It happens to me once or twice a year: all ten toes itch like a mofo. It comes at random, but usually around fall and spring. It might have something to do with large temperature changes, but no matter what I wear, I still haven't found out how to prevent it happening.

I've tried a massage, hot mud pads, cold gel pads, icy-hot balm, going to the sauna, painkillers (the non-addictive kind), and I'm nearing the bottom of this small bottle of bourbon because it's driving me insane.

If anybody has any suggestion, I'm all ears.

 

Hey y'all,

I have a problem: sometimes I find a cool video on Youtube and I want to post it in a community I moderate. So I create a post, put the Youtube link in the URL field, and several options get added to the form:

  • Copy suggested title:
  • archive.org archive link
  • ghostarchive.org archive link
  • archive.today archive link

I click on the first one to copy the title, no problem. And usually that's it: I post, the post's preview shows a snapshot from the video and clicking on it sends me to the Youtube video. Great!

Now here's my problem: I would prefer not to link to Youtube directly So I tried replacing the direct link with any of the 3 proposed links, and it doesn't go all that well:

  • The archive.org link seemingly never works
  • The ghostarchive.org link works but no preview image is generated, which makes the post a bit boring
  • The archive.today link redirects to a archive.ph link which is account-walled

Does anybody know how to create a post with a preview image that links to a Youtube video archived someplace else?

And yes, I'm aware that I could also report the video on my PeerTube. The problem is, SDF only has limited resources and I'd rather not upload huge videos there. They don't need the burden.

 

What a fabulous passive articulated foot!

It's very light - about half the weight of a real foot - and it looks easy and cheap to manufacture, so that everyone could afford one. In fact, it looks simple enough that most parts could be 3D-printed.

Earlier this week my company bought a LIDAR from Ouster. The LIDAR is a network device: it has an ethernet interface, it gets its IP from a DHCP server and then it talks to whichever machine runs the Ouster application.

The engineers and the marketing guy in charge of evaluating it installed the software on a Windows 11 laptop and tried to make it work for 2 days, to no avail. The software simply wouldn’t connect.

So they came to me, the unofficial company “hacker”, to figure it out. And I did: the culprit, as always, was the Windows firewall. Because of course…

But here’s the twist: because it’s Windows, you need some sort of additional antivirus on top of it. Our company uses WithSecure, which is phenomenally annoying and intrusive, and constantly gets in your way when you try to do any work in Windows that isn't Word or Excel. And of course, WithSecure wouldn’t let me punch a hole in the Windows firewall, because of course…

Anyhow, after trying to work around Windows and the hateful compulsory antivirus, I called IT and told them I needed WithSecure disabled, at least temporarily. They told me to fuck off because they’re not letting an unsecured Windows machine on the intranet.

Fine. I pulled another, older Windows laptop without any antivirus, connected it to an air-gapped router, configured DHCP in the router, connected the LIDAR to the router, launched the Ouster app and… it didn't work.

After 3 hours trying to figure out what was wrong, I finally found the problem: the stupid app is an Electron app built with an older version of Electron that had a bug in node.js that prevented it from working if it couldn’t resolve some internet address.

Sigh… Electron… Because of course…

This was getting too painful and annoying with Windows. So I blew away the Windows partition, installed Linux Mint on the laptop, configured the ethernet interface as a private interface, installed the DHCP server so I could do away with the router, connected the laptop to the guest wifi so the stupid Electron app could resolve whatever it needed to resolve to work, installed the Linux version of the Ouster app, and hey-presto, it worked rightaway.

So I made an account for the guys in Mint and handed them the laptop. They played with the LIDAR for a few hours without any problem, pulled records and files out of the machine on USB sticks without any problem, viewed some Excel files in Libreoffice without any problem.

Eventually the marketing guy asked me:

“So what was the problem then?”
“Windows of course” I said. “What else?”
“Wow. That Linux stuff is really good. We tried so hard to make this work but we never could. But it worked rightaway in Linux. That’s slick!”
“Well yeah, I keep telling you guys Windows is crap. There are reasons and this is one of them.”
“Yeah I can see why you don’t like it. And that Linux desktop is really nice actually. I might give it a spin at home.”

So hey, I managed to impress a marketing guy with Linux 🙂

It shows how polished Linux has become, if ordinary computer users can be convinced this easily now. It wasn’t like that for a long long time and it feels kind of rewarding to know you bet on the right horse all along and you're vindicated at last.
