solardev··on How much do electric car batteries degrade?
It's not about whether it's full, but whether you can successfully make it to a faraway destination in a reasonable amount of time (& not adding hours & days to the trip).

It's not really a "debate", just a consideration. We recently got an EV, and generally love it, but long trips are more difficult. We ended up taking the gas car because the EV would've added 5-6 hours to the trip, due to a lack of fast chargers along the routes we needed to take and the 200-ish mile range of our car.

For around town, it's wonderful though.

solardev··on How much do electric car batteries degrade?
It's not really a comparable concern in gas cars, though. Range matters a lot more in EV because the charging stations are much rarer than gas stations.

If you lose 15% range in a gas car, ok, you have to get off one exit earlier to refuel. No big deal. But if you lose 15% range in a electric car, that is sometimes the difference between being able to make it to the next charging station (especially DC fast charging) station or being stranded by the side of the highway and needing a specialty tow.

solardev··on The value of institutional memory
The "why" can be so important... like you said, I can read the code, but I can't always divine the original author's intents...

Anecdote:

I once (well, many times, but especially this one time) inherited a completely undocumented codebase from a previous "lone wolf", mad genius type of programmer. Most of the stuff he wrote was completely inscrutable at first but really kinda genius once you figured it out.

But one day I was tweaking one of his heatmaps showing solar production on a rooftop from "off" to "a little" to "a lot" to "this is broken", and his color gradient code was a magical one-liner doing strange math as hex operations. It usually went from blue to red to yellow, but would sometimes "overflow" into other strange colors that made no sense. I spent a few hours simulating different edge cases and getting back colors I could not reasonably explain — and which would confuse our users. I talked to my coworkers about it, who mostly insisted "Well, I don't know, but he was a very smart guy, so we should probably just trust him and move on". That was unsatisfying, and didn't really help me close the customer ticket that I was trying to solve.

I kept bugging my boss about it, and after a few days of back and forths and seeing my simulation, he finally agreed to let me reach out to the original programmer (who had long since left the team). I finally got my answer a few hours later. He said, "Oh... that was just some random throwaway gradient I thought looked pretty, lol. I was lazy and wrote it in a hurry and, yeah, it probably bugs out on all but the simplest cases, and doesn't conform to any color standards... glad he caught it."

Sigh, lol... that took several person-days to resolve, when it could've been a simple // #TODO: Use a better gradient system someday

What is a "journal" in this case?

I meant more from a public health perspective, like how CDCs and other agencies are able to collect enough population-level data to work on regional/national health issues (COVID or otherwise) when there are privacy concerns.

Do they have to do anonymization and aggregation the way we do for web analytics?

FWIW, I didn't mean to make it a moral argument. I'm just not personally interested in hunting and fishing, but I don't have an ethical problem with them if done in moderation. Nature is violent and ruthless... a well-aimed shot is one of the less miserable ways for a wild animal to die. And yes, they're absolutely outdoor activities :)

Like you said, it's at least better than factory farming, and in some cases, hunters are an important part of conservation efforts.

I happen to be vegan, but have also had a few friends who hunt & fish. I don't fault them for it, or hunters in general. It's just not something I would want to discuss with them or join them for. Not out of any ethical quandary, it's just not something I want to spend my time doing or thinking about (heh, they're just far less exciting when you can't eat what you catch).

How do we ever manage medical issues at a regional or national level, then?
solardev··on The value of institutional memory
It's not a binary thing... even just a few scattered "why we did it this way" comments in the code base is a lot better than no documentation at all.

Wow, you've had a very different experience, and apparently met very different people (or at least saw different sides of them).

I have never discussed those things with my friends or acquaintances anywhere in the world, across many countries... I don't know anything (or care about) any of them, so I suppose I self-select out of those groups.

The people I end up bonding with (all over the world) are usually because of hiking and outdoor stuff, board games, Dungeons and Dragons, martial arts, history, travel, food, whiskey, couch surfing or hosting, national parks, musical theater, etc.

If someone tried to talk to me about cars, sports, or dead fish, I'd probably just excuse myself. It'd be a huge bore for me and them alike.

I don't doubt what you said, that these are popular topics with men in some parts of the world (especially parts of North America). But it's also totally possible to go through life meeting many people without ever discussing any of those, thankfully...

In the US, I've never met one who doesn't enjoy talking about food, especially boba and banh mi.

Beyond that, it just depends on the person...

Might be a regionalism, but here in Oregon, we don't signal going in, but signal right before we intend to exit. That way the next incoming driver can enter the roundabout and keep traffic flowing. We have a LOT of roundabouts though, like dozens upon dozens, and many of them are over saturated. It may be a local response to the traffic patterns here, not sure.

solardev··on Ask HN: Best way to get a land line for my kids?
You can't just add a phone line option from your ISP? It's all VOIP these days and sometimes it's actually cheaper to get it bundled (if you have a cable modem) than without. Fiber and DSL usually offer it too.

It'll be a bit more than a DIY SIP phone, but a hell lot less hassle.

Also, it's probably easier to just use the smartphons' parental controls.

solardev··on Ask HN: React vs. X
Next, typically. It has enough abstractions of its own that it's best (at least at first) to use it without any additional state management or fetching libs.

The entire React ecosystem is a hack on top of a hack. But Next is most popular among the hacks.

solardev··on Ask HN: Is there a way to get uBlock Origin on Chrome >= 138?
For Safari, there is https://adguard.com/en/adguard-ios/overview.html

There's also the beta/alpha Orion browser from Kagi: https://apps.apple.com/us/app/orion-browser-by-kagi/id148449..., which has built-in ad blocking

solardev··on New colors without shooting lasers into your eyes
It's not the animation itself that does anything magical, but the afterimage (I think that's what you would call it?) your eye produces after you stare at the dot for long enough. The black bar is just a countdown timer for the impatient.

But try to maintain laser focus on the central dot, not letting your eyes move or blink if you can help it. Once the black bar depletes, the circle should start shrinking, and around its periphery (like an eclipse) should be some incredibly vivid, super saturated colors.

solardev··on Ask HN: How do you handle small translations?
Machine translations aren't all made equal though. The LLM ones, especially ChatGPT, are many times better than older systems. They are better writers and translators (of major common languages) than most humans I know... by far.
solardev··on Ask HN: How do you handle small translations?
I think Google Translate has implemented some similar ML too, but you can't really prompt it and specify context the way you can with a chatbot.

I'll usually translate it with chatgpt and then run the result backward through Google Translate in order to double check. It's been excellent every time.

Use chatgpt or deepl. They're much better than Google Translate, especially if you specify the context.
solardev··on Tell HN: uBlock Origin on Chrome is finally gone
I've used Firefox for a few months now and it's generally fine, but noticeably slow and janky compared to Chrome. Several websites just didn't work right and required Chrome. The dev tools seem unreliable, with the network tab often failing to capture requests correctly.

I miss Chrome but won't go back without UBlock.

Hoping Kagi's Orion browser gets better.

solardev··on Ask HN: How can I invest in Solar Power?
Well, there's other benefits to home solar (but I'm biased because I used to work in that industry).

Some people like the idea of owning their own system and offsetting their personal usage. If you get a battery with it, it can help with grid outage situations. You can play arbitrage with time of use billing. You can live off grid.

But yeah, from a pure return on investment perspective, there are easier ways to make money.

solardev··on Ask HN: How can I invest in Solar Power?
Look into community solar: https://www.energy.gov/eere/solar/community-solar-basics

Or virtual power plants.

Or at bigger scales, you can invest in commercial solar companies or engage in carbon trading. It's all a bunch of intertied markets.
