NathanielK··on Factorio is coming to Nintendo Switch
The steam one also makes multiplayer much more convenient. Just click on your buddy and join their game. The open source release is a bit trickier and has you hosting and typing in IP addresses.
NathanielK··on Design the next iPhone
What about making the power button recessed like on Sony Xperias? If you're really worried about camera ergonomics, you can even add a dedicated shutter button. The "focus on half press" feature might be overkill for the iPhone camera system though.
NathanielK··on A little exercise each day improves muscles more than one big weekly workout
What's your current maximum shoulder press, and how's your physique? I've been training the latter, and I am almost certainly stronger than you.
NathanielK··on Declining quality of consumer-grade products – 2009 fridge compressor autopsy
Sometimes they aren't essentially the same, but instead different in invisible ways. DeWalt grinders at Canadian Tire used to use plastic parts where metal was typically used. Outside of the different SKU it was difficult to tell the difference.
NathanielK··on Declining quality of consumer-grade products – 2009 fridge compressor autopsy
Since the only thing consumers use full size PCIe slots for now is for a single GPU, extra M.2 slots isn't that big of an ask. One M.2 keyed for an interchangeable wifi card, one for NVMe storage, and then an extra one if you want to upgrade to more storage later. If you only have one keyed for storage, you're SoL when you buy a bigger one later and it's very inconvenient to move data over.
NathanielK··on Shellfirm: Intercept risky patterns at the command line
Other applications can do it too. I recall the Gnome file browser having a big red warning banner if you decided to launch it with gksudo.
NathanielK··on Dolphin Progress Report: February, March, and April 2022
Wii is pretty simple. If you pay attention, when you launch a game, tge

He controller lights flash. This is because it's reinitializing Bluetooth iirc.

NathanielK··on Russian troops are proving that cell phones in war zones are a bad idea
All registration and homework is online at my college, and signing into anything has enforced two-factor authentication now. Phones aren't optional anymore. K-12 might be a different situation. Still lots of material online, especially post-covid. I don't think many high-schools use enforced 2FA though.
NathanielK··on Chainless electric drive system “Free Drive” for bicycles (2021)
Belt drives are fine, but I don't think they're really the improvement over chain drive they're touted as.[0] If you really want reliability out of your bike, they're both sensitive to dirt and grime and benefit from a full chain case.[1] Definitely a fan of internal hubs for commuting, but they're usually at least an order of magnitude more expensive than derailler systems.

Both enclosed chain cases and internal hub gears have been around over 100yrs though, almost from the beginning of bicycles.

Surprised it took so long for tubeless tires and disc brakes to become popular on bicycles since they've been used on motorcycles and cars for many decades. Otherwise the "gold standard" fancy bikes still exist and still look closer to a bike from 1900 than most bikes on shelf do.

NathanielK··on Science of Fasting
> Working from home has convinced me that a lot of western people don't really need more than one meal a day

A different way to look at it would be that a lot of Western people are too sedentary for more than one meal a day. Not only are they getting fat, their muscles are atrophying from lack of activity.

NathanielK··on First Reflective LCD indoor monitor – 32“ FullHD true-color 60Hz
One of the biggest reasons LCDs are so inefficient is that they block most of the light. Each R/G/B subpixel blocks everything that isn't that colour and turns it into heat. The polarizer also has to block all the light that is the wrong polarization and turn that into heat.

This means that the backlight has to be incredibly bright relative ambient light. So even if you positioned it to harness the power of the sun as a backlight, it'd be a lot dimmer than the ambient sunlight.

The reflective LCD in the OP is nice because the sun is behind you instead of shining in your face.

TL;DR, you'd end up having to squint your eyes anyway since the display would be much dimmer than the sun you're staring at, unless you rigged up some cardboard so you didn't have to stare into the sun.

NathanielK··on Ask HN: Why are there so few fanless laptops with Intel/AMD?
Just duct tape a USB-C power bank to any modern ultra low power laptop. Especially ones with optional GPUs that don't have one installed. There's even software to treat them like the secondary batteries laptops used to have as an option.[0]

NathanielK··on You’re muted – or are you? Videoconferencing apps may listen when mic is off
Business users might get different defaults from their admin.
NathanielK··on You’re muted – or are you? Videoconferencing apps may listen when mic is off
Zoom is really bad for this. On my old thinkpad there is a "mute" button on the keyboard. When you press it, it mutes the mic in windows sound settings and turns an indicator light. I've had Zoom un-mute the mic itself with not notification to the user and the "mute" led even stayed on. In old version of Zoom, the host could unmute you without your consent and this would unmute the mic at the system level too. I resorted to disabling the microphone in the Device Manager so it would show up as unplugged instead. This also disables the popup other commentors mentioned.

It looks like newer versions have unmute-consen which hopefully fix it, but the original behaviour made me feel uneasy and not trust Zoom.

NathanielK··on Two-minute battery changes push India’s delivery riders to switch to e-scooters
Some batteries like deWalts's flexvolt system do allow rearranging the cells. They go full series so you can run efficient 60V tools off them, but swith to partly parallel to charge on a standard 20V charger.
NathanielK··on Two-minute battery changes push India’s delivery riders to switch to e-scooters
Batteries have "C" rating which is how many times you can charge or discharge them in an hour. This magic number is closely linked to battery chemistry. A "6C" battery can be charged in 10 minutes as long as you have the power, while a 10C battery can charge in 6 minutes. You're right that sometimes charging speed is limited by the available power. Don't expect to fast charge a 130kWh Tesla at a 45kW charger or charge a 100Wh laptop on a 18W cellphone charger. In the case of these scooter batteries, you are mostly limited by the batteries C rating. Even if you watercooled them to stay at a happy temperature, you can only push the chemistry so much.

Maybe if they switched to a different chemistry like Lithium Titanate they could chaemrge quicker. For now it is easier to use LiFePo batteries and just swap them out.

NathanielK··on Mac Studio M1 Ultra Teardown [video]
They use CoTS LPDDR memory chips running at the same JEDEC timings as everyone else. Yes, they glue these chips to an interposer board like a GPU with HBM, but unlike those GPUs they aren't doing it for any performance requirements. Keeping it on package just makes things more compact so they can shrink the motherboard even more.
NathanielK··on How to build a bike generator with control panel
Why? Exerting yourself and pumping out the watts forces your body to adapt to that and become stronger. Certainly better than being "efficient" and letting your body adapt to being sedentary.
NathanielK··on The New York Times buys Wordle
$15/yr for the premium version that removes ads. The original game that doesn't connect to the internet is removed from newer versions of Windows.
NathanielK··on Sharp-Bilinear Shaders for Retroarch
I'm still not sure why the NES Virtual Console palette was so dark. My most guess was that it was trying to stay out of the automatic-brightness-limiter range that CRT TVs at the time had. This way the dynamic range between levels was preserved. Oddly none of the other VC emulators had that issue, so maybe it was just incompetence.

3DS VC improved things a bit with each colour palettes tuned for each game, though it brought it's own weirdness.

For pretty CRT gaming, I still recommend the Wii. It's straightforward to hack and install retroarch on and you can benefit from the component video out with many cheap and nice TVs. RetroArch can still be a bear to configure for novices, and the Wii can be a tad underpowered, but the good IO makes up for it. It also has oodles of plug and play controller options.

Sadly there's not too many other ways to take advantage of the 240p Y/Pb/Pr on consumer TVs with emulation.

NathanielK··on Sharp-Bilinear Shaders for Retroarch
It's really neat when the big boys end up doing it right in an accessible way. Nintendo's Virtual Console(VC) releases on the Wii support a lovely 240p over composite/s-video/component. This makes it easy for novices to get a clear image on consumer 480i TV without much fiddling.

Sadly not every VC game supports this feature. It's also hidden behind an undocumented button ritual to enable tje first time.

NathanielK··on Sharp-Bilinear Shaders for Retroarch
This is very neat! It looks like a spatial version of a popular technique MPV uses for temporal interpolation. [0]

As other commenters mentioned, "perfect" scaling is all personal preference. In my experience it does a good job with the usual jutter of 24fps on a 60FPS monitor. Never as impressive of the smooth motion of 60Hz video on a strobed 60Hz display.

Microsoft paywalled Solitaire, never underestimate corporate greed.
NathanielK··on A UX designer walks into a Tesla Bar
Many dealerships install them on all the new cars on the lot, along with protective films and the like. This lets them have a reason for the list price to be well above MSRP without it being a straight dealer surcharge.
NathanielK··on AirPods don't “just work”
The clips that let you fasten it to the collar of your shirt are life changing. Completely elimates the weight of the rest of the cord from your ears and any weirdness when you move your head. I wish more headphones and IEMs came with one in the box.
NathanielK··on Colors in movies and TV: What happened to them?
Oh man, 24FPS shakey cam was rough. Glad it's mostly gone away, it was a good way to get motion sick.
NathanielK··on Google no longer producing high quality search results in significant categories
RTINGs is doing an excellent job in this space. They have a public queue where subcribers can vote on the next product they buy to review.
NathanielK··on Google no longer producing high quality search results in significant categories
Low rigidity in shop tools leads to sadness. Even cutting thin pieces of sheetmetal can be miserable if the blade doesn't stay straight.

Sticking with wood or plastic on cheap saws/drills/mills can be ok, but really limits the kinds of things you can fix.

NathanielK··on Update: iPhone Camera app did not replace person's head with a leaf
The parallax in the video is just a tool since photographs don't have any real depth perception like our eyes do. The small leaves on the foreground and the big leaves in the background enhance the illusion, since they're about the same size in screenspace. Maybe the preview showed a leaf, but it's close enough to skintone I doubt it stuck out to his brain on the little phone display.

In meatspace, his eyes are at a different vantage point focusing on the face, while cellphone cameras try to keep everything visible as sharp as possible.

NathanielK··on LG’s new 16:18 monitor
That's true, it's just a nuisance to set UI scale on them. 1.5x works, but feels like 1440p and everything isn't that much sharper. 1x is like using FHD on a small laptop where you need to squint for everything, and 2x is just two big.
