NathanielK··on Intel's Ponte Vecchio Xe-HPC GPU Boasts 100B Transistors
3 years isn't that old. Unless someone else is footing it, keep using what works for you. The 14nm Intel laptops haven't changed much in that time.

Very small laptops with Intel Tigerlake are on level with AMD and Apple products. They have all the new IO bits (PCIe 4, LPDDR4x, Wifi6) and low power usage on 10nm.

If you wanted a bit more battery life, performance, or just want to try a fancier display upgrading could be nice.

Maybe outside of North America. The automatic transmission had big problems here. Ford tried to game the fuel economy with a cheap unreliable transmission. Unlike other regions which got torque-converted autos and popular manual options, almost all the Foci were sold with a dry Dual Clutch Transmission (DCT). This worked on the highway, but around town is was programmed to "crawl" like an automatic, slipping the dry clutch and wearing out very fast. Big class actions happened and now Ford quit selling cars here, only Mustangs and trucks.

Some older Mercedes might have a lower TCO than a 2018 focus, but only because the focus is disastrously unreliable.

I use Teams for education. I spend a lot of time spelunking through online resources. Unlike file browsers or browsers where you can open documents in new windows or tabs, Teams can only do one thing at a time. The back button is not predictable. Together this makes it several steps behind poking through a public ftp server.
NathanielK··on Show HN: Make continuous reforestation part of your daily workflow
Fruit trees make a mess. The fruits fall if you don't pick it. Rotting fruit smells and attracts insects such as wasps.

There's also frequently a dotted border for inclusive selection and a solid border for exclusive selection. Very subtle. Makes it easy to remember which is which if you know how roads work.

Supercharging refers too any way you increase intake charge (air going into the cylinder) above what naturally happens with atmospheric pressure. Using a big turbine to power it used to be called turbo-supercharging, but now we shorten it to turbocharging.

It looks vaguely phallic from the wrong angle. Not sure if cooking would help.
NathanielK··on Young female Japanese biker is 50-year-old man using FaceApp
I think you are onto something. He's very comfortable with his hobby. Going through his twitter, there are many photos of him doing motorcycle maintenance with his own tools. He also has a broad variety, like an old dirtbike he rides on ice or quirky 90's sport bikes he's keeping alive and modding. I hate to gatekeep, but he's not just showing off the flashiest new things off the showroom floor like "influencers" gravitate towards.

Most of his posts are very casual, but his goal is still to ride the bike rather than fix it everyday so that is the bulk of what he shares. His tone is definitely targeting a less experienced audience. In some of the posts, there's light-hearted trivia about niche topics. He's appealing to a younger generation. Getting new people involved in what looks like an exclusive hobby is always exciting to see online.

NathanielK··on The new Google Pay repeats all the same mistakes of Google Allo
I don't believe you can uninstall OEM apps from the drive of the phone unless you have root permission.

As another comment mentioned, you can disable them for the single user over adb. On my sony phone you can disable OEM apps the same place you'd normally uninstall them in the GUI.

It took some clicking (tapping?), but I disabled a bunch of cruft 2 years ago when I bought the phone and haven't had any issues.

NathanielK··on Why was the Amiga Kickstart 1.x “Insert floppy” graphic so bad?
> Additionally, I don't like the aspect ratio of the floppy disk.

The Amiga used a standard 320x200 pixel mode [1] for it's boot screen. On a normal 4:3 CRT this mean the pixels are non-square. Since CRTs are analog, it doesn't really matter to the monitor, but if you just look at the digital bits without stretching them it looks a little flat.

NathanielK··on Ask HN: What tangible benefits did you get from spending time on HN?
I enjoy Reddit, but it's just not designed for smaller communities in my opinion.

The tricky thing with reddit is that it's algorithm tuned for a daily churn. A small sub, like the one you mentioned, may only have a couple good posts a week, but you will miss them if you don't check every day.

If you only browse the frontpage of your subscribed subreddits, adding any popular subreddits tend to drown out the smaller ones.

NathanielK··on Ask HN: What tangible benefits did you get from spending time on HN?
I think that's another reason I like HN. There is no direct messaging like other social media, so if someone wants to interact with you they need to reply publicly.

It's a small thing, but I think it is an important part of HN.

NathanielK··on Intel Core I7-11700K Review: Blasting Off with Rocket Lake
>Not to mention that the 10900 has a 65W TDP vs 105W for the Ryzens.

TDP is lie these days .The 65W intel chips will use over 200W in most motherboards.[1] The 10 core you're using will use even more. The 5900X would use 130W max.

Watch your temps, your passive thermal solution may not be up to the task and your CPUs may be throttling or dying prematurely.

NathanielK··on Simulating CRT Monitors with FFmpeg (Pt. 1: Color CRTs)
Some older Zowie gaming monitors let you strobe the backlight at 60Hz to work with older software, as well as some modern TVs. It's quite fiddly to setup, but it can be worth it if you enjoy your old 60Hz locked games looking smooth.
NathanielK··on Simulating CRT Monitors with FFmpeg (Pt. 1: Color CRTs)
A perfect 120Hz OLED is still over 8ms of blur (MPRT), a crt is closer to 1.5ms MPRT.

There also are almost no OLEDs the right size for PC gaming.

Hopefully as VR tech becomes mainstream, display tech can improve up to the 1.5ms mark.

NathanielK··on Simulating CRT Monitors with FFmpeg (Pt. 1: Color CRTs)
CRTs have some really nice characteristics with moving content. If you're using an LCD or OLED display now, if you quick scroll or drag a window around you'll see you can't read the text while it's moving. CRTs are different though, they strobe in a way that means motion is always clear.

While film lets you hide these artifacts with clever tracking and angles, it's very obvious with interactive video games. There are tricks to fix this, but consumer display tech is quite inconsistent.

NathanielK··on M1 MacBook Air hits 900 GFlops in the browser with Safari's experimental WebGPU
Just for context, the M1's latency is fairly close to other LPDDR4(x) systems (Tigerlake and Zen3 SoCs). This is fairly typical of LPDDR4 compared to normal DDR4, part of the compromise.

Not the most scientific, but userbenchmark is useful because it has latency graphs available for millions of systems.

Latest gen Intel with LPDDR4x chips is well over 100ns https://www.userbenchmark.com/UserRun/40531587 While the same CPU is almost 40ns faster with SODIMMS of DDR4. https://www.userbenchmark.com/UserRun/40527352

NathanielK··on Toyota Develops Packaged Fuel Cell System Module for Hydrogen Utilization
The heavier feel may not be preferred, but it makes having a flexible, cheap suspension design much easier. For example small carthat weighs 1000kg may be be expected to carrier 4-5 adults, an additional ~350kg. To do this the suspension must be overly sprung (and possibly under damped) for a single driver. A 2000kg Tesla means that even without air suspension or adaptive shocks, it will ride much better with a single driver while still being a capable of a high payload. Having a large battery also moves the unsprung:sprung mass ratio favourably.

Specialty vehicles like sports cars and offroad trucksand where payload rating is not a concern function much better the lighter they are though.

The biggest issue on W10 is that there's no way to even more windows from one workspace to another without several clicks, unlike most Linux implementations that have hot keys or dragging the icon around.
NathanielK··on Fake_contacts: Android app to create fake phone contacts, to do data-poisoning
Under Android, if apps want to be respectful, they can. For example, the Discord Android will fall back to system file-pickers if you block storage permissions. Since there's no incentive to be privacy respecting, very few other apps I've used let you do this.
NathanielK··on Tesla is shifting from nickel to iron cathode on standard range car's batteries
It'll start fine if you fill it with 0W or 5W oil and didn't compromise on the battery. Even -30C should be fine.

Some people fill their car with 10W oil or don't buy a battery with adequate CCA, but that's on them.

NathanielK··on In-car touchscreens are dangerous
It won't be a fad if it's cheaper to add a touch screen than adding mechanical switch gear to cars. I agree with the article though, it can be dangerous. Unless there are legal consequences, I don't see touch screens going away.

In Germany, a driver got in trouble for adjusting his wiper speed on the touch screen, then drove off the road from the distraction,[1] but I'm not aware of other rulings.

> "The touch screen built into the Tesla brand vehicle is an electronic device [...] which the driver of the vehicle is only permitted to operate under the conditions of this regulation without it being a matter of what purpose the driver is pursuing with the operation.

> The setting of the functions necessary for the operation of the motor vehicle via touchscreen (here: setting the wiping interval of the windshield wiper) is therefore only permitted if this is done with only a brief glance at the screen that is adapted to the road, traffic, visibility and weather conditions at the same time corresponding averted view of the traffic is connected ".

NathanielK··on MacBook Pro M1X benchmarks have leaked
"Memory starving" a CPU is almost always a latency issue except with very specific workloads. A double wide memory controller would be very cool if they wanted to make a high performance integrated GPU though.
NathanielK··on MacBook Pro M1X benchmarks have leaked
I believe the problem is that apple has stuck with LPDDR memory for performance (33% more memory bandwidth keeps integrated GPUs happy) and to hit power/efficiency targets (variable frequency).

Instead of a DIMM, LPDDR basically puts an entire DIMM on one chip soldered to the board (or package on the M1). LPDDR topologies tend to be limited in how many ranks of memory you can have, which limits the total capacity.

I think if Apple really wanted to mac a "HEDT SoC", they would switch to "quad channel" (256bit wide) memory, which along with the jump to LPDDR5 would let them sell 64GB/128GB machines. The only existing SoCs with wide memory controllers is the Tegra Xavier though.

NathanielK··on What ever happened to scandium bike frames? (2016)
Frame rust isn't a big deal on bicycle. Even in the 80's high-alloy steel like 4130 "Chromo" has been popular with bicycles. I've abused my 70's mtb bicycle with thousands of km of rustbelt winter riding and my frame shows no worrying corrosion, just surface discoloration where the paint has been scratched.

Carbon fiber is more durable than people give it credit for too, though because it's a brittle material that fails suddenly, larger safety factors should be used.

NathanielK··on AirPods Causing Tinnitus (600+ reports since 2019?)
ANC doesn't ever provide perfect isolation. If you see advertisements ANC it will say "blocks 99% of sound" or "cancels 99.9% of noise" which is equivalent to a 20dB and 30dB drop respectively.

You're right though that it doesn't work as well at high volumes. The louder the noise, the more distortion in the microphone/amplifier/driver, so the efficacy of the noise cancelling is reduced. For example in this THD graph of the AirPod Pro's, at 100dB it adds approximately 3dB compare to the 90dBtest.[1] Going much louder and you'll start getting digital clippings as the built in amplifier won't have enough range.

> . For example, if a car beeped its horn at you while using ANC, i hear it.

Car horns are above 100dB, and at the frequency they are, APD only measures about 20dB of attenuation [2], so that only brings it down to 80dB, which is still very loud.

> ANC is merely for constant low background noise like airplane engine. What I find very neat is that even though only 20-30dB of isolation is measured, many noises really do "go away". If you play around with ANC you'll realize that as the background noise gets louder, the white noise hiss from the ear piece gets louder. This mostly the result of error in the system, but this increase in background noise has the effect of masking any external sounds that make it through. I believe it also moves a lot of that energy to higher frequencies where you don't notice it.

NathanielK··on Strategies to Reduce Brain Fog and Improve Clear Thinking
More indoor lighting can make a big difference, especially for folks with Seasonal Affective Dissorder.

CO2 can also cause brainfog, so measuring CO2 content and cracking open a window can really make working indoors less constricting.

NathanielK··on Strategies to Reduce Brain Fog and Improve Clear Thinking
Fiber too. Nothing quite clears the mind like going for a walk and emptying the tanks.

It's not just phase mismatch. There is error in the frequency domain, both from the digital processing going on and the physical characteristics of the driver.
