How much is this mitigated by well-behaved charging circuitry?

I.e. my understanding is most devices are not like the 3s lipos I put in my hobby robots, but instead have integrated charging circuitry that you just give an appropriate voltage to... and that proper charging behavior avoids a lot of the dangerous scenarios with lipos?

I ask because, loosely, the # of battery fires seems like a function in part of: (1) use of good charging logic; (2) cell manufacturing quality; (3) # of cells in the wild. While the growth of 3 probably dominates the improvements to 1 and 2, I'm guessing the number of battery fires has grown but not "exponentially".

The 'Acquired' podcast episode on Ikea speculates that their "buy in person" was historically a cost advantage (especially over pre-assembled furniture that cost $$$ to deliver), as they didn't have to pay shipping/delivery. In the modern era of "expect free shipping as long as some minimum amount is spent", online sold and delivered sales have less profit margin, and one could imagine an intentional business decision to try and keep the in-person experience the "preferred" one for customers.

I always enjoyed documenting things. So got great delight out of carefully asking the few questions I was really stuck on on stack overflow... and then half the time later coming up with a solution and adding that good answer.

(Mostly this ended up being weird Ubuntu things relating to usecases specific to robots... not normal programming stuff)

Thought at first this was maybe just being applied to external product demos, but this reads like dev demos, too:

> Since most of the time you're demoing something you previously worked on, this prevents you from working on current stuff right up to the demo, because you're worried you might break your local setup for the demo by installing different node modules, switching to different Git branches, etc.

This isn't the case for me generally... probably more of problem for web-apps things I guess.

I keep multiple workspaces locally for the multiple things I'm working on, but that hasn't been my pain point. Usually it's that I'm demoing a work in progress (not my choice generally) that has rough edges.

I enjoy the internal demos where questions can be asked about doing XYZ, and that can be shown if it's quick. Recordings tend to take away from that, and be less memorable/engaging I guess.

>> The bulk of the rents is captured instead by providers of health-care services such as hospitals and the system’s true money-makers: insurers, pharmacy-benefit managers and other middlemen taking advantage of its opacity.

> As always, no one reads anything.

The implication of the article was the "bulk of the rents" applies to healthcare costs in total, not just to drug costs. I.e. drug costs are not a huge part of the healthcare costs.

That by itself doesn't guarantee an understanding of why specific medication costs are sometimes 10x or whatever of other 1st world countries.

(but I didn't read the article; just the rest of the comments)

Yep! where the green arrow is pointing is what I was ascii-lustrating

That was my general sense. And that "nominal" is really easy to identify visually with a (relatively slow) scan. I'd guess that means it's a clear quality control thing you (i.e. battery pack makers who are buying the cells) can expect the better manufacturers to do, and pay a slight premium for.

FWIW I found the report's summary (a few days ago when this was also discussed) essential for clarifying for me what the linked "article" was talking about regarding "anode overhang" and "edge alignment".

To summarize it myself, the battery is cylindrically wrapped sheets of anode/cathode material, and you want the top edge to have a straight line consistently having the anode layers (|) sticking out beyond the cathode layers ()

edit: Welp, the unicode I illustrated with got stripped out; so trying again with pipes

    anode
     cathode
      a a

The pics with red and blue dots didn't immediately make this obvious to me, but made sense once I understood the "overhang" meaning.

I think your comment and claims would be much better if you at least gave some example spitball numbers.

Kayak.com does it... it's very much a UX choice of whether to show combinations of flights at a given "level" (economy/main/1st class) or instead dedicate the space to showing the prices at all levels, and only show a flight at a time.

Oh yeah, definitely. Great for my own "throwaway" or rushed projects that I want to revisit, too :D

This issue with READMEs in particular has driven me nuts for the decade I've been doing ROS related robotics stuff. So many repos where the only surface clue (i.e. before diving into the code) of what it does is your interpretation of its name.

But I'm pretty sure it's universal, like you allude to. And not just open-source; but at work, too. I feel like I'm the only one in my company that makes PRs to edit the READMEs to explain what a repo is for, and what repos it might relate to. (I was much happier in the past when we had a couple mono-repos; now the trend is every little project gets its own undocumented repo, alas.)

What I think of as the classic teardown style by iFixit is not a service manual, e.g.:

Ok, seems I rubbed the wrong way there; I was not trying to take away from that key point of your post.

Something called Nexstar, which owns a subset of ABC whatevers was maybe first? I stopped trying to understand it after a while; notably, the yahoo article which (I skimmed/searched before I came to HN) doesn't mention this I guess?

https://www.hollywoodreporter.com/tv/tv-news/fcc-jimmy-kimme...

So yes, seems there was a middle step between Brendan Carr on a podcast, and top level ABC decision making.

Thanks for the numbers! I had no idea taxes were such a large fraction elsewhere. Good to know/consider. I'm most familiar with California. (and actually can't give a % that is taxes offhand)

After the first year of having PV, I determined my own payoff time of about 5-7 years, so that was nice and self-justifying, and haven't dug deeper into details on that.

Curious where you are roughly located; Does that 80% include the distribution of the electricity?

Should I interpret the 20-25% returns as being, your annual savings on the utility bill are 20-25% of the cost of your PV install?

Depends somewhat on if your hardware moves around or not :)

I wonder what the relative fraction of those doing software development that also have to touch hardware is.

I'm not a font person, but the font on the article site makes the zeros look like lower case o; feels like a decision trolling those with a peeve about fonts where 0O look the same. (this was particularly noticeable in the comments where folks talk about e.g. the Nokia N900) At the same time, I don't object to the font's style of having numbers that go below "the line".

Sure, but not relevant to a post countering

Gotcha! When going back to sanity check before my comment, I clearly was skimming too lightly to pick up on that.

While the bug is how soon the cutoff occurs and the prompt is shown...

Comparing the dialogs; did the 15-day expiration dialog have a "purchase" button at the time of the bug? (its screenshot in the write-up does not.) Making the purchase easy to initiate with the purchase button seems like something that would increase conversion rate, too.

Only 2 GB iso! Smaller than Ubuntu! ... I remember when Ubuntu 14.04 was 1 GB ISOs... oh that was a decade ago :(

Thanks for the clarification. Wild to me I didn't know this external lock button was a thing (my car's 16 years old... but I drive a rental a couple times/year...).

I'm probably completely missing the (presumably relatively common) scenarios you have in mind where stolen cars are used for violent crimes. (I'm assuming reckless joyriding isn't what you're referring to as "violent crime"; maybe that's my issue)

To offer an anecdote: I've been used to doing `:e!` with vim. I recently finally had a reason to move to nvim... and it's been auto-updating my buffers when I do stuff in `aider`. Very much a, "oh, ok that's nice!" and I haven't dug further.

I also am a fan, and find it much easier to successfully suggest byobu to others with its simple "F-key to action" mapping of common actions. I work with a bunch of non-developers, so the lower barrier to use is important :)

Aww, they ~~paywalled~~ login-walled(?) the calculator since I last used it (my saved link of https://www.nytimes.com/interactive/2014/upshot/buy-rent-cal... also redirects to your 2024 version)

What I think they're referring to is their sheer size (ratio of customers or $ invested to staff) has meant historically the annual % fees on mutual funds and other investments have been lower than at other institutions.

It's... less unique to Vanguard these days, as several of the large providers have equivalent low-cost funds you can invest in; but 15 years ago it was more significant, iirc.
