technobabbler··on Ask HN: Does being single hurt your productivity?
Hah, didn't realize Deus Ex had a Morpheus too. Thought I missed a Deus Ex x Matrix crossover.

Was there an alternative dialog line that would let JC agree with Morpheus?

technobabbler··on Ask HN: Most Reliable Modern Refrigerator?
> first - I didn't say that you would or wouldn't. I said it isn't "surviorship bias", the reliability and repair-ability difference is absolutely real.

Sorry, wasn't challenging that part, just bringing up an adjacent point. I apologize, I should've been clearer. I definitely believe the difference in reliability and repairability.

> At a 4% interest rate, and .12$/KWh, a modern fridge @450KWh/yr for 10 years costs NPV -$933 for electricity and say -$1000 to buy it. And old fridge @1800KWh/yr for 10 (more) years costs -$1750. So you'd save about $200 with the ancient fridge, not counting having to manually defrost it.

Thank you for doing the math here and making a convincing case for it. That's actually quite a bit better than I thought. However, electricity is already up to .25$/kWh in some states, and probably only going to increase in the years to come as fossil energy becomes scarcer. That changes the math a bit, but not drastically so I suppose. Refrigerators don't use all that much power to begin with anyway, considering the utility you get out of it.

> And before you say it - there is no "repairing over and over". You need to put about that $200 into like it every 20-30 years, every other generation you hand it down to.

Conversely, modern fridges in my experience aren't THAT unreliable either. If something breaks it's usually the ice maker or like a door seal, and many people will just let that stay broken. It's rare to see the actual fridge part break completely... in my very limited experience.

> Still if electricity doubled in cost, or you just like auto-defrost, or live with other monkeys, it's probably not worth it. But the difference isn't "vast". It's pretty negligible because on the whole, fridges don't use a lot lot of power.

Hah, sorry, I see now you've said the same thing.

> Instead of buying a new fridge because I have to, I should buy a new one because it's 2x as efficient and it's a better value proposition when faced with rising power costs. It'd spawn the right kind of obsolescence not fake bad design obsolescence.

This would be nice. FWIW, I know of a company that hand-builds ultra-efficient fridges out of a small town in America: http://www.sunfrost.com/

They're not very big... hard to compare with the mass-manufactured Chinese stuff... but just glad there's SOMEONE out there still making old-world hardware.

technobabbler··on Ask HN: Does being single hurt your productivity?
So many variables. It really depends on who you are (your personality and individual needs and preferences), what your support network is like, whether you have a project that you're working on, how your would-be partnership affects your time, etc.

If you're 20 and stuck in a dead-end job and horny and partying all the time, maybe a partner would help control those urges and make you both lead more fulfilling lives. Or maybe you'd both accentuate each other's weaknesses and spiral down together into a hellhole of addiction and self-loathing. Who knows?

If you're 40 and relatively established in your life and career, a good partner can do wonders for keeping your life contentment high and your routine healthy. It's good to take a break from work once in a while, and when you return to it, you'll be more rested and motivated. It gives you side benefits to your work too (vacations with your partner, weekend outings, whatever) so that when your work projects aren't going well, you can at least be motivated by those side benefits.

Regardless of your age, being together with the wrong person can drastically fuck up your psyche, especially if there's a lot of drama (insecurities, paranoia) or abuse (emotional, physical, verbal) or trust issues (cheating, control issues), etc. That can be way, WAY worse than being single... trust me, there are worse things than loneliness.

In my very humble opinion as a late-30s millennial, loneliness is best tackled not by a romantic partner but by deep and fulfilling friendships in which you can share both activities and emotional connections and good conversations. That both decreases your tendency to put all your eggs in one basket (becoming codependent on a partner) and also teaches you the day-to-day and emotional framework to learn to work with, not against, your own emotions. It teaches you a bunch of coping strategies when you're feeling down (e.g. doing something fun with a friend that doesn't physically hurt you like partying does), conflict resolution skills, etc. And those same skills transfer over to a good partnership so that if and when you find a good one, you can grow that initial romantic attraction into a lasting and mutually fulfilling partnership, without being overly dependent on that other person to the point of suffocation.

I think there's a mix of conventional wisdom here, from "no man is an island" to "you can't love someone else until you love yourself". I don't think either extreme is true; we are by nature both communal and individualistic creatures, and a healthy social life combined with periods of reflective introspection can give you the best of both worlds. But the modern dating culture -- fast swipes and short stays -- are antithetical to building lasting and meaningful connections. If you can sidestep that urge to date fast and furiously for the sake of sex, and focus on building meaningful friendships and connections instead, romantic or not, IMHO you'll be a lot less lonely over the long run. The best partners are also great friends.

But that's just my perspective. Everyone is different. Some people very much so, if their genetics, culture, upbringing, personality, etc. are drastically different from mine. Some thrive on long periods of hermited productivity. Others need constant social connection. There's no one-size-fit-all approach to this, you just gotta keep testing and evaluating your ideal position on the social spectrum. If you're lucky you'll find a good balance, and with time, the physical brain development and emotional maturity that makes it all more bearable and eventually enjoyable.

technobabbler··on The high cost of IKEA furniture
Everything is dying, all the time, everywhere lol. It's hard to keep up anymore... people using up resources way faster than they can be replenished, and it's only getting worse...

I think this is a topic of continuing research. Probably the New Republic doesn't dive too deep into climate research?

One original article from 2008 made the case that they suck up a lot of CO2: https://www.nature.com/articles/nature07276 (or https://sci-hub.hkvisa.net/10.1038/nature07276)

But this finding was challenged in 2021: https://www.sciencedaily.com/releases/2021/03/210325150055.h... (or https://sci-hub.hkvisa.net/https://www.nature.com/articles/s...)

Edit: Dunno if climate is really the best argument there anyway. The old-growths have high biodiversity value, and are hard to regrow. Carbon is more or less a fungible commodity that can be sunk in a billion other ways.

technobabbler··on Show HN: I built an open-source web hosting platform for static sites
If you're willing to go off Amazon altogether and lose a lot of control (which can be good or bad), the serverless hosts like Vercel can easily do that. Each folder is just its own repo, and each repo is its own route, and they take care of all the hosting and managing and CDNs and such. You just git push and that particular website will build and publish in a few seconds. The prices range from free to cheap for small websites.

Thanks for the link!

PS If you ever see something like that on regular Wikipedia, please add the {{Jargon}} tag to it. In theory, at some point, some editor might come and make it better.

technobabbler··on Ask HN: Thoughts on PWAs (Progressive Web Apps)?
They're not fully supported by Apple, and is really just a way of bookmarking a webpage and caching it. They don't use native APIs or GUIs and IMHO are very clunky for users because they pretend to be a app but in the end just look and feel like a chromeless browser, without a lot of the usual UI shortcuts a real native app would have (context menus, touch to do whatever, etc.)

I strongly dislike them, personally. If you really don't want to learn native languages, maybe something like React Native would be a better balance. PWAs are just janky.

OK, then we disagree.
technobabbler··on Ask HN: What will it take to destroy the ads market?
shrug Then don't watch those. Nobody owes you content. If you can't agree on a price point satisfactory to you and the content producer and host, then... move on with your life and go for a walk?
technobabbler··on iPhone lidar with applications for the geosciences
Yeah, portrait mode is basically face ID in reverse and works a lot better than room scanning.

How does the lidar help with night shots though? Maybe focusing, but otherwise isn't it just a long exposure with algorithmic corrections?

technobabbler··on iPhone lidar with applications for the geosciences
I think we generally agree. I'm just saying it's not good enough to take into a cave and casually scan it into a 3d model yet, not with the cheap consumer tech at least. I don't think those results are usable for anything (games, sharing, measurements, mapping), just novelty.
technobabbler··on iPhone lidar with applications for the geosciences
The lidar plays a trivial role in that. Most of it is just algorithmic photogrammetry. If you turned the laser off you'd probably still get similar results.

And it's a gimmick because it's a tiny niche of people who do that, and I wish I didn't have to pay extra for a phone for a lidar. Would take a fingerprint scanner any day. Or a headphone jack.

technobabbler··on iPhone lidar with applications for the geosciences
Yeah, that and uv would be cool for looking at plant life.

The seek and flir imagers are cool for IR

technobabbler··on iPhone lidar with applications for the geosciences
You really think those are fantastic? The only ones that seem even remotely good are the knew where the camera rotates around a static object (couch, whatever). For the room scale ones, the results are terrible. Like this one of the sketch fab hq: https://sketchfab.com/3d-models/sketchfab-hq-scanned-with-ip...

It looks like something out of a video game dream sequence where your world is falling apart.

Thank you. I wish they included that basic description on the home page.
technobabbler··on Ask HN: Most Reliable Modern Refrigerator?
You'll spend way more in electricity than you'll save by keeping and repairing the same ancient fridge over and over... Their efficiency has vastly improved.
technobabbler··on Ask HN: Most Reliable Modern Refrigerator?
I really doubt there's much of difference between brands and models. Old tech built by a few OEMs with some plastic molding thrown on and white labeled every which way. Cheaper to just replace the rare failure than to find an entirely different higher quality refrigerator pipeline if the MTBF of those things are measured in years regardless of brand.
technobabbler··on Tried to charge my phone (with USB-C), but my laptop started getting charged
Then you'd never be able to fully deplete one battery to charge another,no? They'd just reach equilibrium at some point?
technobabbler··on Ask HN: What will it take to destroy the ads market?
When people start paying enough for subscriptions.

Yoi don't get ads if you pay for YouTube, or if you pay enough for most streaming services. Most papers and such offer an ad free subscription tier too. Cancel TV and use YouTube TV if you must.

For Google, there are ad free competitors, or just use ad block.

They'll be around as long as the financial incentives are there. Micropayments failed so many content providers are moving back to pay walls again, whether it's Patreon or adult videos or Steam or whatever. Gotta put food on the table somehow. If you don't want to see ads, just pay for the producers' time some other way.

technobabbler··on Ask HN: I am seriously worried about security in FreeBSD
Hmm. Isn't there something to be said about running a less popular stack so the drive-by zero days won't affect you as much? Sure there are slower fixes, but also fewer people hunting for exploits. You're a less juicy target.
technobabbler··on iPhone lidar with applications for the geosciences
The lidar on the phones suck (I had one and was super disappointed). It has a range of like half a room, terrible resolution, was slow as heck, and the software was buggy and unstable and the algorithms often butchered all but the simplest scans. It's not like you put the phone on the tripod and you get a Ubisoft-like cave in a minute. It's like you get half the room at 20% fidelity after an hour of frustration.

Honestly the more mature photogrammetry techniques that stitch together multiple photos (from video or 360 shots taken successively) seemed much more impressive. Indeed, you can run most of the same apps with lidar off and still get similar results. There is a lot of depth info when you take pictures from different angles that a smart algorithm can figure out. The lidar adds more hinting but without professional grade equipment, the optical sensors (cameras) are much higher resolution and range.

The lidars on the i devices are cheap gimmicks.

Edit: just to add a bit more detail, lidar basically gets you a point cloud of depth data. The professional ones have big spinning mirrors that blanket the room in a matrix of powerful dots, like a Kinect on steroids. That takes a lot of power and, usually, moving parts.

The iPhone one uses more modern, smaller solid state technology but has a resolution of a few hundred dots and a range of 5m, vs the millions of pixels on the optical camera and a range of however much ambient light you have.

The lidar is an active emitter. It has to produce its own laser light, limited by its emitters and battery, and have a way to scan its emissions across 2d space (x and y axes) or else have a ton of micro lasers in a grid.

By comparison the optical camera is just a passive receiver, accepting reflected sunlight or light from the the weak LED flash. Those light sources are way stronger and more diffuse in terms of range and coverage.

Maybe in a few years the lidar will get better but for now it's just not useful for anything except face ID. Prosumer drones probably have better lidar and also better photogrammetry software.

I think those are no longer supported or something. Intel gave up on realsense AFAIK.
technobabbler··on iPhone lidar with applications for the geosciences
IMO phones are so stagnant now that manufacturers just tack on random things to see what sticks. Lidar! Radar! Refresh rate! A 7th camera! Oooh.

Who the hell uses any of that stuff? But it lets them keep releasing new versions and charge huge amounts for new flagships.

Those gimmicks help to prevent the phones from becoming the next race to the bottom that the PC and cheap Android markets have become.

technobabbler··on How did this many deaths become normal?
The Atlantic is a left leaning mag. From that perspective, the "how could we let it happen like this" was, I believe, specifically about the culture wars: ie how could so many reds let their neighbors die because they valued mask freedom over lives.

As a society we've normalized individual freedom over collective lives as a new value, something which wasn't true in, say, the WW2 era of collective rationing. Half the country was fine letting millions die because they believed some youtuber on masks and vax.

technobabbler··on EU to make it mandatory to use customer-replaceable batteries in household items
I couldn't read the original source (foreign language) but I thought the OP was just about mandating replaceable batteries. If it's mandating a particular connector instead, yeah, I get how that would be bad. USB C is a total shitshow that not even the manufacturers and standards bodies can get right. I wouldn't trust any government with that sort of fine grained oversight. Even the cookie law was a disaster.

About electric cars though, case in point, they are a market that people have been clamoring for right to repair on. Not necessarily so they can hack the firmware themselves, but so that they can take it to their local mechanic for repairs instead of the dealership. I understand there is something of a cottage industry of places that can service some Priuses and Leafs etc but some newer cars are too locked down for third parties. That's essentially a DRM thing and hampers innovation in the post sale services sector, anticompetitive OEMs who want to prevent cheaper third party components.
