I was buying a receiver and speakers in 2020 and when it came time to pick out speaker wire, the salesperson walked over to where the wire was and began the pitch...

Salesperson: so when the frequencies are higher the electrons end up traveling only on the outer layer of the wire instead of in the middle...

Me: yeah, skin effect, I did electrical engineering

Salesperson: ah, so I guess you know you don't need this then (pointing to gimmicky monster speaker cable that had a single strand of wire in a spiral around the main bundle with a clear jacket so you can see it)

Me: correct (grabs the cheapest 16awg)

Not true. Corruption happens in digital signals quite often. The effects are different of course: packet loss, garbled audio, the green dots the poster you replied to described. I have seen it all.

If it "worked or not" we wouldn't need things like checksums or error correction.

Source: did electrical engineering, then 25 years in networking.

I have one of those Bolts.

Not only was the battery replaced, the 8 year warranty on it was reset. Also, the idea that EV batteries die after a couple of years like in phones was unfounded. The batteries in EVs are actually properly temperature regulated unlike the ones in mobile phones. The primary degradation in an EV battery happens when the battery is new and stays basically flat for the rest of its life.

EVs have been on the road long enough for studies to determine that most batteries will last at least as long as most people will own the car.

That is correct. There is a trick where you can set the source ip to the ipv6 mapped ipv4 ip it originally came from. I have implemented that in a transparent tcp proxy I worked on some years ago, but I am not sure if nginx supports that.

I should look into that actually. It would be useful to me as well.

Edit: actually that only works if you are in the routing path. However a nat64 solution would work as well, where you map a /64 back to the proxy.

I have dealt with a lot of units over the years, both consumer and professional. I have had more non-battery issues with APC ones than the Cyberpower ones, especially with the rack mount units.

For batteries they all have a lifetime, so I don't trash a brand simply because the battery dies. That will happen to any UPS battery. However it is well known that APC floats the batteries too high resulting in slightly more runtime at the expense of battery longevity. I have replaced more APC batteries as a result.

All of that said, at the consumer level I just tell people to go buy whichever one is on sale at that moment since at least one of them usually is.

As other people have mentioned, this can be a hard problem.

However, malls are typically surrounded by massive amounts of space used for parking. There is a plan for the largest mall in my region to convert all of that land into residential spaces, 2000 apartments. The parking will be moving underground.

Seems like a decent idea to me.

I recite IPv6 addresses on my company networks from memory all the time. It helps that we got a bit lucky on our allocation. There are no letters.

Plus it's really easy to number subnets in a way that makes sense.

Here is an excerpt of the table of contents for the book "Linux Application Development":

  • Process Primitives
    • Having Children
    • Watching Your Children Die
    • Running New Programs
    • A Bit of History: vfork()
    • Killing Yourself
    • Killing Others
    • Dumping Core
  • Simple Children
    • Running and Waiting with system()
    • Reading or Writing from a Process

It's actually quite a good book.

This is likely the issue. Both of those woods are famously incompatible with normal stains. Gel stains are what most people recommend for those woods. I have also had decent luck with Saman stains with the right preparation and great results with Omnia natural oil.

Which is Natureworks PLA. I suspect a number of the types listed in this thread is as well. Eureka is nice in that they list exactly which source material it is right on the spool. Plus they use cardboard spools with the empty spool weight listed. Brilliant.

Just because you have a job doesn't mean you are good at it.

I have an an electric car that has a 66kwh battery and I track everything. It's not even in the top 3 categories of usage in my house. It only runs a few hours when I plug it in, which is 1 or 2 times a week. It also only charges at night, because the car has this super advanced technology where it can tell what time it is.

Every time these stories come out all of you people come out of the woodwork with your "the grid can't handle it" bullshit, but it seems you all haven't got the slightest fucking clue or are just being disingenuous. All you do is regurgitate long debunked Facebook myths and repeat them for every new story that mentions EVs in any way hoping to convince some more suckers.

The power company in my region is literally telling people in advertisements they should install heat pumps and buy EVs. Why the fuck would they do that if it would collapse their infrastructure?
