  • Scroll down a bit in this article. There’s a list of what each of the available keys are required to provide. A “key” in this context is basically a notch in a certain location, which then defines the meaning of the various pins of the connector. Some devices have multiple keys, as some of the specifications have a common subset. Like key A+E is common, because E provides almost everything that A does, so a device that only requires the common interfaces can work in both. Cars that rely on one of the exclusive interfaces will have the specific key of course. This A+E communication is often used for WiFi cards.

    Sockets always only have one key though, for obvious reasons.

    Edit: correction/clarification











  • That’s not actually a solution when talking single-use either. Remaking the bottles from recycled glass is incredibly energy intensive and not an environmentally friendly process either. Multi-use bottles are much better, but the cleaning required also isn’t that simple and also relatively energy intensive (far from remaking the bottles of course).

    There’s also practical downsides to glass (heavy, breakable), but those are subjective and their relevance highly depends on the use case.

    Ideally, we wouldn’t buy stuff to drink in any kind of bottle, but just use tap water. possibly just buy some concentrated stuff to then make your actual drink at home. Nothing beats the effectiveness of transporting water through a simple pipe, but that isn’t even possible everywhere in the world due to drinking water quality issues…


  • One of the basic rules is that “you can’t prove a negative”. You can only prove it by it contradicting something that has proof, which isn’t gonna work for something like this. As a plain example: you can’t prove you were not at McDonald’s at 8 o’clock last night, but if there’s video of you being somewhere else at that time it proves it only because it would require you to be in two places at once.

    So the best you’ll probably do is promising really hard that you did your best to look for it? The problem is that it may well exist, but hasn’t gotten any traction and might be a 1 person thing in some repo somewhere, undocumented and badly searchable with a bad project name.



  • The “key” of an m.2 defines what the pins mean, basically what signal they carry (PCIe, USB, …). There’s a nice table here, if you scroll down a bit. Some are extensions to others, and are pin compatible (meaning the things they have in common are on the same pins).

    A key and E key are very similar, while E just provides a few more interfaces, but importantly A doesn’t provide anything the E doesn’t. So any card that can work in A can also work in E. This is why A+E is so common: they don’t require the Mainboard to provide E, only A, but both will work so both notches are present.







  • I’m addition to all the comments you’ve already gotten, this is highly dependant on where you live. The cultural differences on how common or even expected an “I love you” is varies wildly. It’s also a very personal decision that quite honestly it’s hard to ask for advice about.

    That being said, I’d always prefer to hold it back initially, even if that’s how you (think you) feel. Months (multiple) is a good measure to start of with. Also the reception can be very different depending on the perceived implications. Some people literally run when they hear it, some run when they don’t hear it, which is why this is such a personal judgement call. Not just depending on you but also your (potential) partner.
