I would tend yo disagree a bit with the other comments. First of all, let's talk about the scratch. It does not looks very deep, so most likely no damage to traces. In order to have a short you would also need to have two traces exposed and some metallic object between the two. This also look unlikely to me. I would clean the area with isopropyl alcohol, check it visually. You could also cover up the scratch with nail polish.

Then, the missing capacitor. First of, I cannot make from the picture if there was a capacitor soldered there in the first place. Sometimes there are purposfuly unpopulated components. In any case, all of the capacitors you are seeing on the backside of the CPU are decoupling capacitor. They serve no other purpose than to help stabilize the voltage versus the dynamic power draw. This means that less capacitors equals less stabilisation, but not necessarily incapacity to function. I would clean also clean it up and ensure that no metallic object touches the pads. I would probably not try to replace it, as you have no way of knowing what value the capacitor is supposed to be (usually no schematic/boardview for modern products).

It is theoretically possible to damage the CPU due to a short, but likelihood seems very low to me in this case. I would clean it up, check visually, and try to turn it on.

Oh god, I never considered that .* could theoretically match ... Thanks fish for not doing that, more than likely saved my unknowing ass a couple of times

It's not a matter of "him" personally. Permissive license allow for a work to be taken and redistributed by other entities, without enforcing them to release their changes. This creates a one way relationship that is generally detrimental to the open source ecosystem, allowing work to be stolen away from the public. That being said, choosing a license is situational, and a permissive one can be a great choice in certain instances. For that particular case, I don't see much benefit to having a permissive licence.

I believe it does. Weakly reciprocal license like LGPL is not equivalent as a permissive license like Apache. I see two main things on the top of my head:

  1. This ensure that no one can license wash ffmpg and e.g. use rockchip's repo to distribute their own private product based on ffmpeg without publishing their changes
  2. It ensures proper attribution of the work, which can have an impact on the developer's careers and ffmpeg as a whole.

On top of this, it really should not be complicated to license this code properly (unless rockchip wants to allow point 1, which is illegal)

The fact that a capacitor is marked with a 1000V label does not necessarily mean that 1000V are present on its terminal (but you should use caution). I don't think the voltage makes it out of the realm of electronics.

It's quite hard to answer your question, as the board is quite dirty and you provided a single picture. You could check for continuity and capacitance value with a multimeter

Turns out that this is common in Japan for tea fields. They mount big fans on poles all accross the field for it (you provably have to zoom in to see them)

I feel very out of the loop here. Can someone please explain what is going on? There's always been some mockery online about some of Gnome's stance (minimalism, app indicator) which is annoying, but does not seem too bad. But full blown targetted harassment? Why on earth would someone target them specifically?

Hey! Props to you for trying something new. While the through hole components look OK, soldering large gauge wire can be quite tricky, especially if the soldering iron is not powerful. What soldering iron do you use? In these cases especially, it is important to wick the wire first, wick the soldering pad and finally assemble the two. Raising the iron temperature for this can also be useful (I sometimes use 400° or a bit higher). It is counter intuitive, but hotter iron means quicker soldering job, and less heat in the surrounding area (e.g cable's insulator)

Pretty nice but unfortunately no shipment to EU :(

The green and orange colors are quite typical of the phoenix contacts brand. It's not a perfect match, but this model is very close: https://www.phoenixcontact.com/en-us/products/printed-circuit-board-terminal-sptaf-1-7-35-il-1861988

I don't know so much about EGS, but probably some of the following (most of which I don't use very often, I hope I recall correctly)

  • Refunds
  • Family sharing of games
  • Sharing games for other local users
  • Being able to lend games
  • Remote Play (with friends)
  • Remote Play (stream for a local machine)
  • Linux support through proton
  • probably more?

Actually, a least some cars (probably more than you think)/have some sort of "emergency" breaking signal, which often result in the usual breaking signal blinking for a while. You need to seriously slam the brakes to see it though. E.g: https://m.youtube.com/watch?v=j_osu1WgGMU

There is also a nice technology connection video talking about braking lights for electric cars and in general, which can be dangerous.

As a first step, I would recommend checking out osm.org from a computer. Once logged in you can use it as an editor straight from the browser. The embedded documentation really helped me initially.

I did not know about this mounting method. Probably it's a way to improve passive cooling capabilities?
