I can't find my github repository, it's out there somewhere...

In the meantime I zipped up the schematics and micropython code

Ade, we're drowning in bot new user requests -- I can't handle them any more.

I can't help you here - I don't have the permissions - but try putting a block on any IPs from Singapore: Most of the bots seem to be in data centres there these days. Other countries which are problematic - China obviously, also Brazil to a slightly lesser extent.  But Singapore is likely your culprit. I've blocked them from MEM & LEF using iptables rules & just blocking out giant ranges of IP addresses. Sadly, that does cut a few legitimate users off, but it also keeps the server afloat.

Thanks Ade but I don't have the permissions either. Just a mod.

Can you not get a good 9mm or some thing to sort them out :D
PS: AdeV, Tony STILL only has the rear bodywork to Paint and the Ford40 will be finished.
Been that way for 3 years...Motor sounds ace. you need to get down here and see it.

The GT40? COOL!

Where's he based? I'd love to pop down & see it, even if it's not finished, I bet the old man would be interested too.

I never kept his contact details unfortunately.

Braving the cold, Ihad to try it.

It really is a jungle of all kinds of possible and impossible options, no matter if it's Linux or Windows.

But yeah, enabling 32-bit repository is one of the first steps in the Wine installation instructions mentioned before: sudo dpkg --add-architecture i386

General stories and gripes ahead:

Must have Win apps that I use with Wine are ancient Paint Shop Pro 8, and Goldwave.

I'd use Winamp too, but it's rather quirky to use with Wine. Sudden crashes and whatnot. I've always used it in its basic form (since Win 2000), without any fancy visualizations.

Winamp is probably the only music player that has a working plugin to re-connect to the network stream, when it cuts out. It's called 'silence detector'.

On to the alternatives. Although VLC has 'Auto re-connect' option in its preferences, it doesn't work the way one might expect, if at all. After trying some bash scripts found on the net, (and even ones produced by the infamous ChatGPT) to fix the problem, none of them worked. Got to love the dead air.

Qmmp, Audacious, and bunch of other players don't seem to have that function either.

Anyway, then I thought, that how about looking, what's happening when the stream cuts off. Wireshark is a free tool that I used back when testing Win10 to see where it sends telemetry data. If memory serves, there were tutorials of how to do that.

When using it in this case, I got some indications, when the net radio stream cuts or drops, but can't figure out what to do with that data.

So, I have a habit of jumping to the deep end of the pool, even though I can barely swim  [ You are not allowed to view this attachment ]  .

In that vein, another example: trying to make GPU (display card) passthrough, so that the VM has a real hardware resources (3D acceleration for apps like Rhinoceros that I've used quite a lot on Windows), instead of virtual ones. It may be possible using single GPU, but it's really not that convenient to use - shut down the primary host display service/device, so that VM can use it.

I insisted on testing that procedure anyway, and since such things can't, for obvious reasons, be tested inside VM, I ended up bricking the Linux installation on my pc.

More viable option would be to have two GPU's, perhaps just an integrated one for the host, and dedicated one for VM. However, my motherboard or CPU don't have integrated GPU's, so that's the end of the story about that, for now.

All too blooming complicated for me these days - bring back CP/M is what I say.

Happy New Year everybody.

This black resin is really sticky stuff when cold, cleaing it off was a bit of a bugger.

The case clips together, so Im not at all sure if it'll come apart in one piece

Santa brought me a garage door for an early Christmas present, he's also bringing me a P1S/AMS combo as a late Christmas present.  The gaping hole in the front of my garage is now filled and the building is weather-tight.  Insulating it, or any other work on the inside, is going to have to wait for warmer weather.

I tried printing some larger than 200mm stuff  on the MP10 and it crapped out again, that's why Santa's bringing me the late present.

I also decided it was time to install the Micro Swiss all-metal hot end on the D6.  In the process I discovered the root cause of the jamming issue I'd been having on it.  The D6 uses an aluminum block with a series of slots milled in it as a heatsink for the heat break.  This block is bolted to the bottom of the extruder drive, which caps off the open top of the slots.  The cooling fan blows air through the slots to cool the heat break.  The Micro Swiss all metal hot end replaces this heatsink with one of their own design.  I found 2 things that were issues with the original heatsink.  First, at least 75% of the cooling slots were blocked off with dust,  This would cause heat creep, and eventually the filament would be melting in the heat break, not the nozzle, causing a jam.  I'm going to have to blow these slots out once in a while or the same thing will happen to the Micro Swiss heatsink.  (When I found that issue I almost regretted ordering the P1S, until I remembered that to get a quality print out of the D6 I have to print at 60mm/sec, while they recommend 200mm/sec on the P1S.)  The second issue I found was that the slots that were right next to where the heat break went through the heatsink had no exit, they were dead-headed so about 25% of the heatsink NEVER worked properly.  The cooling fan could pressurize the slots, but that air would be static so it wouldn't help cool the heatsink.  Those slots didn't have any dust in them which shows no air was circulating through them.  The Micro Swiss heatsink has an exit milled in for these slots. 

I finally found some 1/4"x1/2" aluminum flat bar for the RT7's upper frame rails, so I'm going back to Plan A and using the aluminum frame rails.  They'll be a little easier to machine on the equipment I've got.

Hi sorveltaja, just to maybe help/explain why wine in many current Linux's doesn't work with many older programs (like in my case, old free Google SketchUp 8 3D-CAD, which is essential for me), we need to also install 32bit compatibility architecture for wine to handle these older 32 bit programs.

I also need that 32 bit compatibility to run my older Dell laser printer driver in CUPS. If you find mysterious problems like the above two in using windows programs or drivers, this may be a solution. Many linuxs now support only 64 bit applications and drivers out of the box. But for most there is an addon to allow you to also run 32 bit legacy software.

In Puppy linuxes from Fossapup F96-CE on back, they do not use apt or synaptic to load programs, but include a special Puppy Linux package manager that handles that stuff without using the console.

In later Puppy Linuxes, Bookwormpup64, and on, they do include apt and Synaptic, but also a degraded Puppy package manager. They have (to me) the same problems of needing to use the console in many cases to make an installation. HOWEVER, now there is a move to make a large number of applications available as appimages. These do not require a package installer at all. You simply download the application to your hard drive, make a shortcut to it, and then it runs itself. In other words, it acts a lot like a Windows program, without needing any installer.

None of the above Puppy types require sudo or su to work in the terminal. They are considered single-user systems, not multi-user, so there is no need to isolate multiple users from the administrator. The user and the administrator are all the one -- the computer owner. This is how Windows 98 used to work, as well, and all early computers.

But I also rarely needed to use the terminal in Puppy Linux. Sometimes I'd use it to check a printing cue via the command "lpstat" or clear it. Or occasionally I'd run a program from terminal instead of clicking on it graphically -- that was useful if it was a new program that crashed silently. In terminal you would get the actual error messages that happened in the crash, and you could troubleshoot the cause.

But that was pretty much all the need I had for using the console. I contrast that greatly with the period, about a dozen years ago, when I used Ubuntu. There was a constant need for troubleshooting, and installing, and correcting issues with the terminal.

Okay, enough about Puppy Linux as an historic background -- I stopped using it after 10 + years about two months ago, in favor of EasyOS. Really, to me, EasyOs is a highly developed Puppy, by the original developer of Puppy, although he doesn't say that.

In relation to what I wrote above, one very big feature is its Package Manager, which I think is the best I've ever seen, and most comprehensive of any I've tried. It can load a great variety of different application types into EasyOS : .debs appimages, flatpaks, .pets, .sfs and it does a lot of behind the scenes work automatically -- for instance refreshing the file list from the repositories for .debs. It also offers to run any application as a restricted user, or as root, your choice at installation time.

Another advantage of EasyOS is that it can take a snapshot of your system and store it at any time. If you ever have problems, you can always revert to a former snapshot.

The entire system upgrades seamlessly with the push of a button, but can be also rolled back to a former snapshot or system version. The speed of upgrade is amazing, because it only downloads a differential file from your last version.

All of your user data is encrypted automatically, also. And your browser can be run as its own user, so it does not have admin access. It is isolated.

Well that's enough, but I think it goes further to give a context for the fact that apt, synaptic, and sudo, are for me rarely needed, and terminal is used very occasionally only for troubleshooting, unlike the old days for me, using Debian and Ubuntu.

Again, this is not meant to in any way be negative about other Linuxes, and there are a huge variety of them. it's just an expression of my own personal preferences about how I like to work on my own computer. Obviously there's a learning curve for any Linux, and I've experienced that these last few months in transitioning from Puppy Linux to EasyOS. But I definitely think it was worthwhile. It's a very fast system with a minimal footprint, and huge capabilities in terms of available programs.
