Bilbo Bagshot : I used to know this guy, Minty. He had a dog who he'd train to attack rich people. He was into the whole class-war thing. He called the dog Gramsci after an Italian Marxist. Rumor has it, it could smell wealth from up to 20 feet. The thing is, it all backfired. Minty won 100 grand on a scratchcard and Gramsci bit his knees off.
Tim : That's terrible.
Bilbo Bagshot : Not really. He used the money to buy new knees.
22 ft unsupported seems like a very long span to me, what's that nearly 7 metres?
Sounds like it's getting into the realm of structural enginneering not diy for me.
If you want to save costs you might think aout a "flitch beam", that's 2 wood beams with a steel plate sandwiched in between - the three components are bolted together every few feet. Easier to join to the timbers then. https://www.youtube.com/watch?v=QWUNd559UQY
I still think you might be more like 10"x2 or even 12"x2 timbers to cover that span if totally unsupported. But might still come in a little cheaper than the i-beam.
Maybe the roof will be very lightweight and no snow weight is expected - but I'm no structural engineer so don't take my word for it.
Other features like corner bracing or canti-leverage, or some other support structure or other feature (like is it the bottom side of a framed gable triangle) might also help.
Generally studio/mixer/DJ audio tools like audacity or mixxx will probably do most stuff like this.
But they might be a bit overkill, I think you could just use two instances of VLC.
Change "stereo output mode" setting, to left on on instance and right on the a second instance.
I'm not sure if this will blend left and right signals before output though I'd guess it probably would.
i don't think my preferences line up with what you're after, so maybe ignore this. . . .
i'd recommend explaining computers youtube and website for beginners - he'll give you much better advice than me https://yewtu.be/channel/UCbiGcwDWZjz05njNPrJU7jA
but FWIW i reckon mint+xfce. will give you "easy" and "decent performance on old hardware"
you can try out the more flashy d.e s on a usb boot drive see if you think the features are worth it on your setup.
always remember it's easy and cheap to experiment.
get yourself a system for backing up your "home" directory, - a couple usb drives is easy enough.
and i'd also recommend starting a text file list of all programs/packages you like to install.
you can make it into a bash "sudo apt get " script (for debian based) if you're feeling super lazy.
, or just run through it manually whenever you switch.
also do the SSD upgrade as soon as you can afford it, it'll make everything a lot better
