- Comment on Tech support 'trained monkey’ fixed problem with two fingers 1 week ago:
I can understand why some programs only allow a single copy to be opened at once, something like email makes sense. However on Linux they got this right… if you try to open a program that is already running, it switches to the screen that program is on and restores the program window to the desktop. There’s no guessing why the program “won’t open”, it just makes the logical choice that you want to see it.
Heh that reminds me of another detail from that call… the guy also wasn’t willing to reboot his computer (which would have solved the problem as well), but berated me for not knowing what I was doing for making the suggestion. Dude, it’s Windows, things break constantly and a reboot generally resolves the issue.

Oh I have no doubt he got angry that the IT guy made him look stupid. Everyone on the support desk already knew his reputation so it wasn’t going to get any worse with us. I wish I had been around long enough to see what happened with his next demotion, because there was no possible way he was going to last even a year, I just can’t figure out how he made it to such a high initial position in the first place (unless he fudged his resume and got hired into it).

At one time I worked for IBM, supporting a nationwide company. There was a top guy who (like in the above story) thought he was hot shit. I think he was something like the CFO, but his ineptitude was recognized and he was pushed out. This company allowed people to move to a lower position, and he always thought he knew more about computers than everyone else, so he took the position of CTO.
One day I got a call from him, ranting that Outlook wouldn’t open and these computers were hopelessly broken. The normal procedure was to remote connect into the caller’s computer to directly fix any problems, but he decided he was smarter than the tech support people, and refused to allow me to access his machine. Fortunately I had direct contact with the on-site tech guy, who knew what he would be facing and went to the CTO’s office.
When he got back a couple minutes later, I asked him what the issue was. “Outlook was already open, it was just minimized to the task bar.”
- Comment on 3D Printing Bed Levelling (Traming) - Simple Concept 2 weeks ago:
Yeah I think there’s some good ideas that have been built up with the ABL devices over the years, and that mesh leveling seems great. However I also feel like more people should take the time to get their beds physically as flat as possible first, because otherwise your printer spends a lot of time micro-stepping the Z, and I’ve seen some mesh maps that looked absolutely horrible.
Playing around with arduino devices, I have some laser rangefinders that seem like they could work well for an ABL. That might also be a good way to map out the idea I mentioned about creating a thin full-bed shim to get a truly flat bed, and after that perhaps you would only need to do a fast four-corner calibration with the ABL to make sure nothing has changed.
- Comment on 3D Printing Bed Levelling (Traming) - Simple Concept 2 weeks ago:
I’ve never had auto-leveling on my own printer, but the one at work has it and I wouldn’t want it. It was great for the first couple years, then the sensors started suffering from corrosion and now it just doesn’t work for crap.
So on my own printer (fully manual) I have always treated the paper test as nothing more than an initial step to make sure the nozzle doesn’t plow your bed during the leveling process. It will get you close, but not close enough. To really dial in your bed, you need at least a 5-point 1st-layer print test so you can really get that initial layer adhering nicely at all points, and this of course performs the calibration with the bed at full heat so it matches conditions during actual prints.
The biggest problem I had was my aluminum bed was badly warped when I got it, but fortunately just bowl-shaped. I cut CD-sized discs of aluminum foil to build up the center – 13 layers in total, then put a glass or G10 bed over that to really get a flat surface. I finished mine with a PEI sticker on top of the G10.
Another problem is that all beds will be completely unique from each other. I have one of the original Ender 3 Pro printers, and purchased a Creality glass bed with it. There was nothing that wouldn’t stick to that bed, and I used a 10mm calicat (which has 4mm feet pads) as my tests for all new filament. Clean the surface occasionally with 91% ISO, and life was good… but after a few years the surface wore out and I was forced to get a new bed. Ordered directly from Creality again, and man, nothing at all would stick to that piece of glass, even for large prints. I tried everything down to brake cleaner to solve the problem and finally gave up on it. That’s when I started working with the G10. The point of this is that you can tell someone a particular bed will solve all their problems, and you will be wrong. The reality is that sellers use different manufacturers to make their product and you never know what you’ll get.
Your observations about the bed warping from the tightness of the screws is interesting, I never thought about that part before. I have heavy springs under my bed, and I have always suggested people get those springs as tight as possibly without being completely closed, then adjust the Z-switch to that point before you start your leveling process. Tight springs means the screws should never wander. It’s been around 3 years since the last time I even touched my leveling screws, and I just fired up the printer and ran some new pieces last week without any issues. A good tool is one that you can ignore for a year, then use it without having to recalibrate. Anything else is just frustrating!
There are a lot of suggestions we can make to help newcomers get their bed leveling correct, and there are a lot of variables that we simply can’t account for including manufacturer defects. One idea I had years ago but never got around to trying is to print a thin sheet of filament the size of the entire bed, ironed to create a top surface perfectly flat to the nozzle but taking up any imperfections in the aluminum plate. Then put a thin bed over the top of that, and you should have a perfect surface that lasts nearly the life of the printer. Seems like a good idea, but how do you figure out where to fill in those first layers until you have a final layer that covers the full bed?

Oh I have a pretty good idea about that… But I was actually referring to the fact that Trump’s platform was the first thing attacked after he bombed the country. Yeah it would be great if we had a government that was focused on letting the various agencies do their jobs rather than dismantling everything that keeps us safe and healthy.

That’s a good point, although flashing does help to grab attention, but it can also be annoying when the person is driving with their foot on the brake pedal.
- Comment on Front Brake Lights Could Drastically Diminish Road Accident Rates 5 weeks ago:
Wow that’s got to be almost worthless. As you say, it just takes some idiot with a load obscuring the vehicle lights and suddenly nobody behind them knows what’s going on. What’s next, are we going to make tail lights optional?
- Comment on Front Brake Lights Could Drastically Diminish Road Accident Rates 5 weeks ago:
Does your state not require good lights on the trailers? I just built a new trailer last year, I was required to have full working brake and turn signals along with running lights, but I went the extra step and included more brake/turn lights on the front and rear of the fenders, along with reverse lights plus four marker lights along each side. Trailers are hard enough to see, I didn’t want to make it harder for anyone by just sticking with the bare minimum.
- Comment on Front Brake Lights Could Drastically Diminish Road Accident Rates 5 weeks ago:
I suspect a lot of that has to do with the entitled way people are driving these days. If you leave a car length gap, some kid will wrecklessly attempt to cram their way in because your lane momentarily moved slightly faster.
- Comment on Front Brake Lights Could Drastically Diminish Road Accident Rates 5 weeks ago:
I suspect because there’s no consistency in the brightness of vehicle lights. But that’s one of the reasons why I think an incremental light bar would be better, there’s no variation between vehicles. You could even make it more informative by flashing the whole bar when you first brake, so someone behind you can more easily see how much of the bar is being lit up.
- Comment on Front Brake Lights Could Drastically Diminish Road Accident Rates 5 weeks ago:
That could probably be implemented in most existing vehicles, and at least it would provide more information.
- Comment on Front Brake Lights Could Drastically Diminish Road Accident Rates 5 weeks ago:
I still think rear signaling could be improved dramatically by using a wide third-brake light to show the intensity of braking.
For example – I have seen some aftermarket turn signals which are bars the width of the vehicle, and show a “moving” signal starting in the center and then progressing towards the outer edge of the vehicle.
So now take that idea for brake. When you barely have your foot on the brake pedal, it would light a couple lights in the center of your brake signal. Press a little harder and now it’s lighting up 1/4 of the lights from the center towards the outside edge of the vehicle. And when you’re pressing the brake pedal to the floor, all of the lights are lit up from the center to the outside edges of the vehicle. The harder you press on the pedal, the more lights are illuminated.
Now you have an immediate indication of just how hard the person in front of you is braking. With the normal on/off brake signals, you don’t know what’s happening until moments later as you determine how fast you are approaching that car. They could be casually slowing, or they could be locking up their wheels for an accident in front of them.

You might check if a simple CPU upgrade would get you there. I previously ran some 2005 Poweredge servers that came with a Pentium D processor, and it cost me something like $8 from ebay to upgrade to a Xeon and start running KVM.
- Comment on What are the minimum or recommended requirements for a personal home server? 1 month ago:
Keep an eye out for people trashing perfectly good desktop machines because Windows 10 is being retired.
If you want a server that “does it all” then you would need to get the most decked-out top of the line server available… Obviously that is unrealistic, so as others have mentioned, knowing WHAT you want to run is required to even begin to make a guess at what you will need.
Meanwhile here’s what I suggest – Grab any desktop machine you can find to get yourself started. Load up an OS, and start adding services. Maybe you want to run a personal web server, a file server, or something more extensive like Nextcloud? Get those things installed, and see how it runs. At some point you will start seeing performance issues, and this tells you when it’s time to upgrade to something with more capability. You may simply need more memory or a better CPU, in which case you can get the parts, or you may need to really step up to something with dual-CPU or internal RAID. You might also consider splitting services between multiple desktop machines, for instance having one dedicated NAS and another running Nextcloud. Your personal setup will dictate what works best for you, but the best way to learn these things is to just dive in with whatever hardware you can get ahold of (especially when it’s free), and use that as your baseline for any upgrades.

I’ve said it before and I’ll say it again… a social media post is NOT an official government communication.

- Comment on How to easily add a backup internet connection to your home office - and why you should, A failover internet connection is a good idea if you work from home - and it's not complicated to set up. 3 months ago:
So ldirectord is kind of a front-end for ipvsadm. The tools allow you to set up load-balancing between internal servers. I run each service in a VM, and I have at least two copies of each (on separate physical servers). Ldirectord lets me configure how frequently to verify each machine is up, a list of primary servers, and an optional backup when the others go down. Overall it works pretty smooth.
Shorewall is similarly a front end for iptables, allowing a more structured set of configuration files. I’ve been trying to start using Webmin for the first time because it has some nice management of shorewall, maybe I’ll be able to clean up some of my config, but I’d also like to get traffic shaping configured.
I have a dedicated firewall (just moved to a poweredge R620 last night), a NAS, and two VM systems to run services on… all run from home. I enjoy setting things up to play with, so this has all been built up starting from old desktop machines and expanded over time.

I tried playing around with opensense awhile back. Wasn’t impressed and kept running into things I couldn’t get it to do for me, so I stuck with my existing setup. I use ldirectord for load balancing between servers and shorewall lets me generally balance the traffic between WAN connections. It works pretty well but there’s a lot of moving parts.

Does anyone else use a Linux firewall to manage dual connections? I run Shorewall here, but I haven’t really had much luck with traffic shaping to keep the majority of traffic on my primary connection while allowing low-speed info like email to split up between connections.
- Comment on How do I fit a network card with a physical x4 slot into an x1 slot? 3 months ago:
If your card has an x4 pinout, then it probably needs the additional bandwidth. Plugging it into an x1 slot (if it was possible) would slow down the network traffic. Get a better motherboard with an x4 slot on it so you can use the hardware you want. or find something else that will fit your computer.
Honestly even the 1Gb quad port card I have requires an x4 slot, although I saw some dual-port 2.5Gb x1 cards on ebay. Maybe you could just use two of those?
- Comment on openscad is pretty great 4 months ago:
Even the older versions work pretty well, depending on the features you need. I use it for all my 3D modeling, I could never get the hang of other CAD software but this one just “makes sense” to me. I even used it last year to create a model of a trailer I wanted to build, worked out the finer details of how everything would fit together and some options like adding ramps, and once we got to the point of building the trailer it was just a matter of copying the dimensions and cutting out all the steel.
