It definitely help for re-world modeling, getting things figured out in advance. In the Spring of 2024 I decided to finally build a utility trailer I've been thinking about for years, and I modeled the whole thing in OpenScad down to the wiring and generating material lists (and yes, we got it built and have been using it through this past Summer). The fact that you can't incrementally update variables makes some tasks stupidly difficult requiring a lot of needless redundancy, but I do like being able to write stuff out as code.

Maybe some day I'll try Build123 or something else, but most of my projects are things where I just need to whip out a quick model, so I don't want to deal with learning a whole new system at the same time. Case in point -- yesterday I picked up a keyboard fro the thrift store but realized it was missing one of the folding feet (this one has two different sized stacked feet that fold out from each other). Half an hour later I'm making my first print, and another 15 minutes I'm ready to test the second foot piece. And I could have done it faster if I didn't spend so much time capturing the details of the original feet. Point is, it's hard to change when most of your needs are quickly covered with the existing software.

I've been using openscad to create a dual-filament direct drive print head for my Ender 3. Got the whole thing printed but I have to run a couple more wires up the cable harness to control the new servo and read the filament runout sensor.

Honestly, are there any HDDs that can really reach 6gb/s speeds? I haven't seen any that could reach 3gb/s. My current array is all running on SATA-2 backplanes, but with 8 drives in the raid it clocks out at 460MB/s sustained (bytes, not bits). Considering my previous NAS could barely reach 70MB/s on a 6-disk array, I was quite pleased with the new setup.

I mean, my SUV is a 2004 and seems to be holding up pretty well. I give it full synthetic oil and take it off-road occasionally, so it gets a wide range of treatment. Maybe I'm just not as bothered as other people are by the occasional bit of maintenance. I just replaced the thermostat this Fall, which was certainly a lot harder than on the old car because this one is buried down along the side of the engine, but it was still a pretty simple job.

It was a '74 Pontiac LeMansthat I bought in 1987. And sorry, I did forget about one thing... I had to replace the transmission a couple times, but back then you could get them from a junkyard for cheap, and it only took a couple hours to replace. Probably would have lasted a lot longer if I'd taken the time to rebuild the clutches though. Of course it's not like you can drive any vehicle forever, there was the maintenance as things like bushings and alternators wore out. For this discussion though I don't count things that you have to do on any vehicle with 300k miles on it. Everything wears out eventually, and yeah even the motor was starting to smoke by that time.

That's what rich people are for -- to suffer for the benefit of the working class.

Never buy new. Let someone else deal with the frequent hassle of getting all the problems fixed "under warranty" while the lemons get sent to salvage. Give me the vehicles that survive. Case in point, I bought my first car for $500, drove it for 24 years, and the biggest age-related expense was rebuilding the front end for $600. I sold the car in 2011 for $1000. I bought my current SUV in 2009 and the biggest mechanical failures have been replacing the power steering pump and the 4WD short axles.

I had a friend who insisted he needed to spend all his money buying new cars. He tried to tell me how much money he was saving because the dealership was fixing all the problems for free. I pointed out that he had barely even driven his new car because it was spending more time at the dealership every week or two and he was constantly wasting his own time taking it back for yet another problem.

How to live forever. Oh wait...

If they weren't on X and were reading reality-based information, they would already know the entire world hates Trump's politics, and I certainly don't blame anyone for hating the entire US in general. Too many people here will gladly hate an entire country even when they had no say in choosing their leaders, so it's only fitting to see that attitude thrown back at us.

On the other hand, the exposure that all these Trump-supporting "influencers" are foreign bot accounts is hilarious, and I love that MAGA is finally being shown exactly who they've been listening to.

Your server needs to have a static IP address. Once you have that, and have your DNS service set up, then you should be able to update your domain(s) to point to the new DNS. This new server doesn't have to be your primary DNS entry for the domain(s), but it should be one of the first two entries. And that's pretty much all you need to get started.

One other consideration is setting up the master/slave status of your DNS servers so you only have to make updates in one spot (helpful to ensure everything stays in sync). This isn't a requirement, it just makes your life easier.

Ah ok, that makes sense they can sue later. Thanks!

I'm just wondering why the fine is only $10k? Something like this where you blow someone away for no reason, you should be forfeiting all of your possessions to their surviving family since the victim will no longer be earning an income to support them.

 

I built a new firewall under Debian 12. The machine has eight network ports, and during configuration I accidentally used the same name for a couple of the ports in the files under /etc/systemd/network/*.link. I ended up with two link files referencing two different MAC addresses but naming each of them as WAN0, and once systemd got that configuration it wouldn't let it go.

From what I could find online, normally I would just issue systemctl daemon-reload followed by a update-initramfs -u and after a reboot systemd should have had the updated information... but no dice this time. The way I finally discovered the problem was when I noticed under ifconfig that my wan0 port was pointing to the wrong MAC address (even though the link files had been corrected).

After several hours of fighting with it, I finally managed to get it to work by renumbering all of my link files, and now the information for each port matches up correctly. But my real question here is WHY did systemd refuse to read updated link files? Is there another step I should have taken which was mysteriously never mentioned in any of the dozens of web pages I looked at trying to fix this? I really need to understand the proper process for getting it to correctly use these files so I can maintain the machine in the future.

(God I miss the reliability of udev already)

 

I'm building a new rack server (Poweredge R620) and am using the option "consoleblank=600" in the GRUB_CMDLINE_LINUX setting. During the setup I used the wrong memory stick and installed Bullseye, and screen blanking was working correctly there. Since I had already finished nearly all the configuration this week, I thought it would be easier to just do a regular dist upgrade than reloading the whole system.

After upgrading to Bookworm and rebooting, I notice that now when the screen blanking is supposed to kick in (which normally just turns off the display), I am instead getting what looks like rolling static on the screen. I have several other R620 racks running Buster so I know the screen blanking should work with this hardware, but this appears to be an issue specific to Bookworm.

Note that even when I try something like setterm -blank 1 or setterm -powerdown 1 I get the same resulting static after 1 minute. To be clear, this is specifically for the command line, I do not run desktops on my servers.

A google search for the problem has been unsuccessful so I'm hoping someone can point me to a solution or help with the proper search terms.

 

I'm wondering if anyone has found (free) sources of data to use for live elections results, specifically the Presidential race? I've been building a map of poll results but would also like to put something together to watch the race tomorrow night.

 

Your dreams and imagination evolved as a view into another universe. As with the current beliefs, you cannot decipher technical information -- no words in books, no details of how devices work, so even if you can describe things you see from another place, you could not reproduce a working version.

Now how do you convince others that the things your are seeing are really happening without being labeled insane? And how could you use this information to benefit yourself or others? Take a peek into the multiverse to see how other versions of yourself have solved these problems...
