You should know that wd is for water displacement. If you are trying to do anything else there is a better chemical you should use instead.

Aluminium is very commonly used. It isn't near as good a conductor as copper, but you can easilly use more toeget results and in most cases that works fine.

The reason we stopped using aluminimun more is it is relly tricky. when you tighten a screw the al deforms over time and so you don't get a lasting connection. Al also corrodes to a non conductive state. Many house fires were traced to al wiring in just the few years it was common. We can mitigate all the above issuses but it takes care and so copper is preferred despite al being much cheaper.

Algorithms done right are useful. Make sure things that are likely important to be bubble to the top. I don't have time to read/watch it all, so prioritize the important things for me.

Done right is the hard part. It is too easy to prioritize memes that make people angry even though if you really investigate you discover that while there is a little truth it is grossly exaggerated and whoever is being mocked isn't that stupid - because things that make people mad tend to get attention.

The algorithm really needs a "there is plenty more but you have seen all the important stuff - go outside and do something" after I've seen what is important. Of course it then needs a "but I'm currently confined to a hospital bed so just show me something so I'm not bored out of my mind". The likes of facebook of course cannot allow such a thing as once you stop scrolling their ad revenue is gone. However that is what the world needs.

How reliable do you need to be - https://solar.lowtechmagazine.com/ often goes offline because there wasn't enough sun to keep their servers up - would this be acceptable for your servers? (you should spend a lot of time on that website when it is up - it will teach you more than anyone else here)

Will you allow yourself to plug in the backup if there isn't much sun for a few days (either yourself or some automatic system) - just the ability to go 20 hours on battery and enough solar to recharge the battery in 4 hours on a sunny day would get most people to 90% solar and will be a lot cheaper than chasing to 100% solar all the time - but that might not be good enough for you.

The general rule of thumb if you never can go down is you need to be able to run for 2 weeks without any sun, and enough solar to then recharge those batteries when there is 4 hours of full sun. Of course the weather where you live makes a difference. If you live in the desert your worst possible day will always be followed by a day where you can completely recharge the battery so you need much less batteries; while those who live in arctic locations will not get any sun for a couple months and so need a lot more storage.

There is a point where a forum is too active and you need to either split it or implement weird and complex rules so things don't get too large.

Best retaliation is more arms to Ukraine - a war that is already in progress and so you don't risk starting a new war.

As if they were not misused by every other president....

Watching someone cut a dovetail by hand is a lot more interesting now that I know from experience how hard it is. And maybe I'll learn a trick to make my next ones better.

Every since the end of WWII there has regularly been things happening that felt like we were steering towards WWIII. You have to learn to live your life, you have no idea in advance what will actually start WWIII. There are of course plenty of signs but you don't know until after WWIII is over what were important. Even WWII when the first shots were fired did not have to become a world war, things just escalated in ways that you couldn't be sure at the time they would.

Don't real the above as you shouldn't work for peace, or that you shouldn't prepare for WWIII. You should be doing both at the same time. The cost of peace sometimes higher than the costs of war - and war is expensive! (peace can sometimes only be had at the cost of becoming a slave - I'd rather my kids die in war than become slaves)

The politics is very left wing and very unwelcoming to any other viewpoint.

Every time I look into Shaken baby syndrome I find plenty of people with real medical credentials say either it doesn't exist, or it could exist but there are other much more likely causes of death that share similar evidence. That leave plenty of doubt in my mind and thus I can never convict anyone of it.

They will ask how you got there. Don't lie if they catch you in a lie that is bad. Walking is fine tell them they can send an officer to verify your car is at home. Move it to the driveway if in a garrage - don't move it off you property though. They probably won't check but make it easy if they do check.
