  • It still happens more than it should. It took me 4 tries to get the nVidia driver to take on my “gaming” laptop with Fedora 40, (it wouldn’t accept the public keys for some reason). And I had to wait for some updates that took 2 weeks to show up. But, the onboard Intel chipset ran Nouveau just fine with no waiting and tinkering. I think people are still having some issues with nVidea and Wayland yet. I know I still have some minor ghosting issues with a couple of AppImages I really need to use that would prefer straight X11 over X-Wayland.

    Now that didn’t bother me because I’ve been using various distros since buying my first boxed set CDs with RedHat 5 from Walmart of all places for $25US. (I still suffer from PTSD thanks to rpm hell). But I can see how a stumbling block like that can turn newcomers to Linux distros off.









  • Most pets don’t work because their owners don’t bother to train them to do any work. And interestingly enough, I have indeed seen a Chihuahua herd cattle. There was No Fear. It was amazing to see that little toothed monster chase a 2000lbs bull around a pen and into another and then into a barn on command from the farmer that owned him. And a Mastiff will gladly hunt fox, cougars, wolves, and even people if you want them to. They will also happily Netflix, popcorn, and chill on the couch with you after chewing up that human also.

    Why don’t my dogs talk? Well, they just don’t have the physical voice box to form the sounds of human speech, (as you well know). But that doesn’t mean they don’t communicate with people. Actions, like tail wagging, barking in various tones and volumes, rolling on the ground all communicate emotions and situational reports. And us humans understand them just fine. My little Russian Spaniel does her best to “talk” to me with a near continuous stream of moans and groans, and erffs when she sits with me in my recliner. It’s almost annoying when she doesn’t shut up. And they understand my communications. My dogs understand verbal, whistle, and silent hand signals and respond correctly and instantly to them when I’m afield with them. Parrots, have a natural physical ability to mimic other sounds, (as do a lot of other birds). So they are doing what comes naturally to them - a human is not required.

    There are lots of dogs out there that do jobs they were never bred for. Seeing eye dogs, dogs trained for deaf people or assistants to people confined to a wheel chair. Turns out Labrador Retrievers are really great at this kind of work. And I have trained retired Springer Spaniel hunting dogs to work in a hospital as therapy dogs. But that’s not why or what those breeds exists for. Ever see a trained animal act at a circus? They are often what most people would call “mutts”. Mixed breed dogs doing amusing things like ride bicycles and drive little cars around and jumping through burning hoops of fire. And you can often see little Chihuahuas preforming in those acts. All doing things none of them were bred for.

    I like the cats that we have. One, a grey and white is an excellent mouser. But he comes from a very long line of barn cats and has a wild streak in him. The other two, are far more interested in cat toys and sleeping in laps and beds than in any mouse - and that’s fine. A warm kitty in the lap purring away is a calming and enjoyable thing to have on a cold winter’s day. But I’m under no illusion that cats or most other pets can be trained to do all the things my dogs can do.

    Dogs are humans oldest and closest companions and co-workers for a reason.






  • If you want to search for AI solutions to problems because forums are either too slow to answer or you get no answer at all. I’ve been using Phind for my Linux issues with Fedora, (a recent switch and I’m not all that familiar with it yet), and it’s an AI that is supposed to be aimed at programmers and Devs.

    So far, for my meager needs, it’s worked VERY well. So between Phind and RTFM, I haven’t found an issue I can’t work through.


  • I’ve never had and issue with the linear rails rusting in all the years I’ve been 3D printing. But I do live in a drier temperate climate also. But dust will eat the seals up very quickly as well. If rust is a worrisome issue, hard chromed linear rods are also easily available to prevent any worry about rust. And they would outlast the the non-chrome rails significantly. That’s what I use.

    As always YMMV


  • It’s not so much about lubrication as it is about trying to prevent seal wear. When the wiper seal gets worn and can no longer keep the dust and grit out, the rolling elements have little time left.

    If the bearing as lubricated correctly at installation time, it should never need re-lubrication. But it’s important to keep the rail surfaces clean. And it’s amazing just how dusty those rails can get and just how abrasive that dust is on the bearings.

    I don’t lube the rails, it attracts too much dust. But I do wiper the rails periodically. I replaced the linear rod bearings and rods on my old and trusty Mk3s+ after almost 3500 hours of operation this last winter. Though I should have probably done it a bit sooner.


  • For PLA and PETG, I like MatterHacker, though I have been buying some Voxel PLA lately and that’s been pretty good stuff too. Voxel does run sales that get the price down to $15/$16US a kilo.

    For ABS/ASA, I’m still using a the same kilo of Zyltech ABS I bought 5 or 6 years ago. And I still haven’t used 200g yet. I did dig it out this weekend to print a couple dozen custom cable clips for my boat with it though.


  • I’m not an architect, but I have stayed at a Holiday Inn.

    The easiest way to think about an element being “structural” or not is is to consider what can happen if you remove that element - will the roof/wall collapse on top of you or not. If the answer is no, the roof/wall will not fall down, it’s not “Structural” or “Load Bearing” If the roof/wall can fall down on if you remove it, it is “structural” or “load bearing”.

    So, using your example, if you were to remove the drywall and furring strips from that cement block wall, will the wall and ceiling be in danger of collapse? If it is, then it was structural. If not, then it wasn’t structural.

    The Architects and Civil Engineers that I have known, do not consider drywall or furring strips to “structural” when designing a building. I’m going with their consensus on this matter.
