  • Yeah, I think I’m going to stick to my energizers … pretty much everything I use AA batteries for these days is a low draw device (door lock, smoke detector) or something like an emergency flash light, rechargeable batteries don’t make sense for either use case.

    I have some old school nice rechargeable batteries as well with an external charger. Those were nice back in 2016 when my bose headphones I was using at the time used AAA batteries, but it’s been a long time since I’ve used those with any frequency.


  • “Unused road” is ridiculous except in extremes. Unless people merge well over a mile back, 1 lane of traffic will make no difference. The only way “unused road” matters is for the people that haven’t entered the traffic jam yet who are getting off before they reach it.

    Very few people (from what I’ve seen) merge more than 30 car lengths out. 30 cars is not going to make a difference.

    What does make a difference is the fact that we can’t do a merge at speed because some people want to “zipper late.” It’s the zipper behavior that matters, the “at the very end” part never should’ve been added to that recommendation.

    Looking at an actual research paper about this, the zipper merge demonstrated is not at the last possible point. A merge point forms ahead of that point and that’s what should be used. The pictures from their study show the zipper occurring over a wide area with many of the zipped cars driving in the middle.

    I don’t know how studies like this have become the recommendations we have. They seem to me to miss critical bits.

    Edit: based on my quick read, it’s worth noting the study finds only minimal support for the zipper merge and only in contexts not involving trucks largely based on visual analysis from their video feed as the quantitative data was not statistically significant. We need better transparency on recommendations like this frankly and the research supporting them. We should be able to have an honest debate on the merits of the papers.


  • The problem with zipper merges as this person describes them is a zipper merge is SUPPOSED TO get traffic back up to speed. However, when your take on the zipper merge is “up there where the wreck is at the last possible spot I can merge” there’s no time for a human to safely merge at speed. So everything has to continue at a crawl.

    So the people jumping out of their lane and “zipper merging” at the last second instead of 50 feet out or so end up making things worse for everyone.

    The zipper does not and should not be at the point of the physical problem on the road. Just like you should not just drive to the end of the on ramp and at the last possible second merge into the lane on your left without paying attention.


  • I really can’t more strongly disagree with this take.

    Zipper merging is to interleave two lanes of traffic when there’s one lane of traffic available ahead.

    It DOES NOT matter if it’s done with 3 feet to merge or 300 feet to merge. There’s no efficiency gain.

    What does matter is some assholes trying to merge at speed at the last possible second.

    The zipper point should not be the point where there’s NO ROOM to merge SAFELY without EVERYONE going 3 miles per hour.

    The handful of times I’ve seen a zipper merge actually start to work, someone rushes down to the end of the line where the problem is, nearly causes a second accident trying to get over, and then everything starts moving at a crawl again.

    You don’t need to zipper merge at the “physical barrier” causing the zipper merge to be necessary.












  • Yeah, it looks like basic reasoning but it isn’t. These things are based on pattern recognition. “Assume all x are y, all z are y, are all z x?” is a known formulation … I’ve seen it a fair number of times in my life.

    Recent development has added this whole “make it prompt itself about the question” phase to try and make things more accurate … but that also only works sometimes.

    AI in LLM form is just a sick joke. It’s like watching a magic trick where half of people expect the magician to ACTUALLY levitate next year because … “they’re almost there!!”

    Maybe I’ll be proven wrong, but I don’t see it…


  • I don’t buy the “it’s a neural network” argument. We don’t really understand consciousness or thinking … and consciousness is possibly a requirement for actual thinking.

    Frankly, I don’t think thinking in humans is based anywhere near statical probabilities.

    You can of course apply statistics and observe patterns and mimic them, but coorilation is not causation (and generally speaking, society is far too willing to accept coorilation).

    Maybe everything reduces to “neural networks” in the same way LLM AI models them … but that seems like an exceptionally bold claim for humanity to make.


  • I actually did try rock climbing, my ex and I did it.

    I proposed going to first time we dated, she got into it while we were split, I would go a few times a month with her, and then basically haven’t been in a few months since we split.

    The climbing gym in my area is on the other side of town and just constantly PACKED and I was also never very good at it … plus I’m colorblind and the routes are color coded which makes it even trickier … so it’s not really my cup of tea.

    But yeah, I’ve done it probably 15 times or so and have my own shoes.

    I’ll probably give it another shot (this time with friends) once it gets cold again (I’m in NE Ohio).


  • Yeah … I appreciate the effort but I don’t think that’s a real answer.

    I don’t want to date half way across the country or world … or slide into other people’s DMs (which is something girls ALSO complain about dudes doing).

    At that point if the answer is “someone’s going to be possibly uncomfortable anyways” I’m better off just doing the cold approach where I can at least read body language.

    Not to mention there are a ton of elements of attraction that just don’t work on a forum.
