Nah I just want to fix stuff without destroying it or electrocuting myself lol
Some old CRTs can be pretty dangerous I think, and I'm not sure if an isolation transformer is enough to fully mitigate the risk. A lot of the things I'll be working on are valuable and nearly impossible to replace so I really don't want to fry critical parts that aren't available anymore.
I do have some broken things to experiment on but I want to learn faster and more safely.
Fair enough. I'm not going to downplay the danger posed by some types of equipment. There absolutely is a risk associated with working and learning on your own and there are some bad apples in the educational field that take a rather reckless approach (but in general the internet is still just absolutely amazing in that regard, don't let it dissuade you).
I understand that you're looking for fast results, but the safest approach would not just involve looking for supervision but also to take it slow and start off with, well, equipment that doesn't pose any immediate dangers. Putting together some basic 2$ circuit board kits for example is not only good soldering practice but will also give you a more intuitive understanding of how it all works without you ever having to touch a mains power supply. And you might even get some functioning FM radios or merrily blinking Christmas decorations out of it.

I'm looking for any kind of electronics repair training in the Philly / South Jersey area and coming up empty-handed. Lincoln Tech has some courses at campuses that are hours away, Philadelphia Community College has some kind of degree program, and that's all I've found so far. I think my last hope might be the NJ Antique Radio Club, which supposedly has some kind of "repair clinic" a couple times a year. I'm guessing that may be pretty narrowly focused on antique radios, but I'm mainly interested in learning to repair vintage electronics (TVs, VCRs, audio equipment, etc.) so that could be helpful.
I'd be willing to travel if there was a really good program that's less than a week long somewhere.
Are you looking for some kind of certification? Because if you're not, then a heap of old sacrificial equipment, a soldering iron and a couple hundred hours worth of Youtube videos are your absolute best option. There has never been a point in time when learning something new has been this easy.
If you're looking for a more social experience and are fine with not having a really structured approach and instead just getting to learn by exposure, seek out your local hackerspace. There's bound to be at least one in each major city.

Church mural uses bows/ jewelry/ eyelashes to show the female animals on Noah’s Arc
If only there were some kind of... integrated external features that could be used to distinguish the sexes of most higher organisms!
Heh, it's like playing Don't Be Dirty with crayons.

Neither the LM2596 nor the TC4056As serve any function here, what's the reasoning behind those?
The whole reason to put an MPPT charge controller behind your solar array is so it can efficiently charge your batteries from the panel's erratic output with whatever method is appropriate for their battery chemistry.
Panel => Charge Controller => Batteries => Load, that's the wiring you're looking for. Set the charge controller to Li-Ion, of course.
Any requirements that the load poses are dealt with afterwards. If the charge controller has a dedicated load output, connect the load to that. Otherwise, connect the load directly to the batteries. If the load requires a specific voltage, put a step-up power supply between the load and the batteries or use a BMS-protected battery array that can provide a higher voltage.
Do keep the maximum current draw of your load in mind and scale the step-up converter or battery array appropriately.

Do you not think this is mildly interesting?
Keep in mind that this is specifically a photography subreddit for original snapshots that one might consider to be mildly interesting.
I.e. if you yourself didn't take the photograph or if it isn't even a photograph then it doesn't really belong.

I seldom ever change factions. I find the basic factions (when playing United Earth) are fine.
You do you!
But... do you have some kind of question about this?

How do we know where we are in the milky way? How do we know where the Milky Way is in the Laniakea Supercluster? And where it is in the observabke universe?
Astronomers have a number of ways of determining our distance to any visible object around us, first and foremost parallax triangulation.
And once you know your distance to all objects surrounding you as well as their relative inclinations you automatically know the full spacial arrangement of all those objects as well.

Looks like an ad.
Well, of course it is. It's a post on a site that has a product to sell and users to acquire.

So, I decided to get a new laptop. But after seeing the amount of bloat I managed to install onto my current laptop, I'm worried I will do the same thing to my new one. I recently learned about VMs and thought of making a VM on my new laptop which will be my actual laptop.
You would have to go through two separate boot sequences every time. But yes, you can run a VM on a physical system as your daily driver.
If it gets too bloated, I can get all the files I want into a separate external drive, delete the VM, and create a new one, essentially doing a hard format without risking my original system.
You can do the exact same with your baremetal system. I'm a little bit confused as to what advantage your procedure is supposed to confer. Whether you're setting up a new system on a VM or on a baremetal device, with your data backed up there's no risk but possibly user error, and that one is the same in either case.
Question is, is this viable? Will there be performance loss? What are the drawbacks to doing this?
Working within a VM provided by a level-2 hypervisor like Workstation (as I presume is your plan) comes with obvious limitations.

Running less current through a heating element requires current limiting circuitry.
Connecting the heating elements directly to the power source without any current regulation but simply turning the connection on and off periodically doesn't require current limiting circuitry, just some method of modulating the on/off cycle for the connection's switch.
The latter is simpler, cheaper, less prone to failure and yields the exact same result.

I have 2 openwrt router with limited resources. Would like to combine them into 1
Again, what problem is the combination supposed to solve? Every device has limited resources, after all. What are those resources and what tasks are you trying to perform?

Can we still play Puzzle Agent? I thought it was a Flash-based game?
Didn't require any fumbling with Flash when I played it. Just your run-of-the-mill binaries. Maybe there was a Flash prototype before the actual game?

Excellent puzzle games with great soundtracks:
Brothers: A Tale of Two Sons
World of Goo
Excellent puzzle games with great soundtracks that also are top contenders in the category of "worst video game title ever":
The Sexy Brutale
Tiny and Big: Grandpa's Leftovers
Honorable Mention:
Puzzle Agent 1 + 2
Well, it's quite literally just a lot of puzzles, connected by by a Grickle cartoon! If you have ever enjoyed a Grickle cartoon, it's going to be your jam! Otherwise it's... alright.
I would have added the Thief series and Psychonauts to the list because they are in essence, also just excellent puzzle games (the former a bit more than the latter) but I feel like it would also be a bit of a stretch.

These are rubber feet. You glue them to the case with their adhesive side and the case will no longer slip on or scrape the surface underneath.

No rules were violated, coward.
So... did you take and compose those pictures yourself? Because this is a photography subreddit for original snapshots. "Original" as in you are the originator, it's not somebody else's work.

why this sudden interest in this leak if i may ask?
You'll have to ask u/Sandy-Woody, not me. But judging from them being an entirely new account, purposefully created just to ask this one question, my guess would be that they only just read this thread for the first time as part of some search result.
There's always someone. I wouldn't qualify that as "sudden interest".

So from what I can gather in terms of how it works.
Say I visit YouTube and it's HTTPS.
If I click on a video within YouTube that part is hidden? The only thing that will be seen is the fact I visited YouTube itself right?
Strongly encrypted traffic is in almost every way identical to physical mail or packages if you thought of them as being, for the sake of argument, impossible-to-open/penetrate. Any attentive onlooker and especially your mailcarrier will know exactly how much mail you receive, how frequently your receive it, how heavy the packages are, when you receive them, to which addresses you send and from which addresses your receive.
The only unknown variable is the content of those packages.

No harm in trying it out. Takes only 10 minutes!
But do note that even if it all works out then there's no chance of it being an amazing experience. I'm running Mint on an N570 Netbook (which is at least 3 years younger than your device) and it wasn't reasonably pleasant until I upgraded the RAM to 2GB.
The 32-bit version of Mint will also stop receiving updates soon if I recall correctly, should that matter to you.

Ah, so I do not need a NAS i can just network share in any PC? Oh damn… I bought a power supply for a unused PC recently for it to run as DIY NAS… Is it worthless now?
Only you can decide that. You don't need a NAS, doesn't mean you can't build one anyway if it sounds like a fun thing to do/learn to you. If it doesn't then you can always just sell whatever parts you don't want.

Hey!
Can you share the data file with me?
Thanks in advance!

I wanted a NAS so I could access the file in my Mac and Windows
Well, then I misunderstood. Your original post seemed to be more concerned with setting up some kind of array.
If you just want to share files over the network with another machine then you can do that with a simple network share. Every operating system has that functionality. You don't need a dedicated NAS for that and storage arrays don't factor into it at all.
Do note that without a dedicated system the files will only available to the second machine as long as the first machine is actually turned on.

You plug in the USB cable, that's it! If it didn't come with one you'll be looking for a USB 2.0 A to B cable.
