Mmmmm, tastes like banana bones!

Sounds decent.

Most routers can have VLAN functionality if you flash them with custom firmware. You get allllll the settings then. I have a netgear router that now has an FTP server and a bunch of other stuff. All you have to do is make sure the model you buy has a chipset supported by the firmware. Firmwares include:

• DD-WRT
• Tomato
• AdvancedTomato
• OpenWRT
• Chilifire
• Gargoyle

I’m sure someone will come in and say that using a consumer grade router is naff, but in my (somewhat limited) experience working with managed switches in an industrial setting, a custom consumer router is much more feature-rich. Unless you need the IO of a managed switch (ie SFPs) I see no reason to go down that route.

If you are using SFPs, be sure to get the knock off ones that can be programmed - there should be places that sell them and program them at no extra cost. They can literally be 1/10 of the cost of the manufacturer’s own modules.

So it turns out the original meme was kind of right? It just didn’t illustrate what it was talking about very well. According to @ada@lemmy.blahaj.zone:

The double slit experiment is about observation.

When you fire photons through the double slits, one photon at a time, they cause wave interference patterns with themselves as if each photon travelled through both slits.

Yet if you set something up to measure which slit each photon passed through, they no longer interfere with themselves, and give you the two straight lines pattern, rather than the interference pattern.

The meme confuses two things in quantum mechanics. One is the double slit experiment, which confirms that light behaves both as a wave and a particle. That’s what the meme is showing here.

However it’s also throwing in Schrodinger’s, which states that until you look at something it exists in all states - the classic theoretical example being the cat in a box, which is both alive and dead until you open the box. That doesn’t make much sense in the real world, but when looking at quantum particles it is provably true.

Here is another meme that more accurately explains things: mander.xyz/post/5143468

Just to complete the set of “principles of quantum mechanics that people know of but don’t fully understand”, there’s the Heisenberg Uncertainty Principle, which states that you can either know the position of something or its momentum (ie where it’s going). The more accurately you measure one of these, the less accurate any measurement is of the other.

Edit: However there’s also what /u/Ada@lemmy.blahaj.zone said below:

The double slit experiment is about observation.

When you fire photons through the double slits, one photon at a time, they cause wave interference patterns with themselves as if each photon travelled through both slits.

Yet if you set something up to measure which slit each photon passed through, they no longer interfere with themselves, and give you the two straight lines pattern, rather than the interference pattern.

So maybe the meme was referring to this variation on the double slit experiment, rather than Schrodinger.
