NwtnsMthd··on California's new tire efficiency rules could save drivers $1B a year
Possibly an unrealistic expectation from the average driver.
NwtnsMthd··on How old is Ann?
18
NwtnsMthd··on 4× RTX Pro 6000 Blackwell on Water, and the One Card That Wouldn't Behave
It's difficult to speculate as to the exact failure from blurry pictures but the solder on that choke (inductor) looks terrible.

Something went wrong in manufacturing. The solder should have wicked to cover the entire pad, not just a small square, and there should be no (brown) discoloration.

NwtnsMthd··on The Rise of the Bullshittery
I'm ashamed to admit, I had too many tabs open to notice :|
NwtnsMthd··on Qwen3.6-27B: Flagship-Level Coding in a 27B Dense Model
Just curious, what's your setup like? How do the devs interact with the model?
NwtnsMthd··on Reallocating $100/Month Claude Code Spend to Zed and OpenRouter
But hey, the dev was generous to give it an MIT license, you could always just fork it and what you like ¯\_(ツ)_/¯
NwtnsMthd··on Make macOS consistently bad unironically
It's not the biggest flaw, there are plenty others, but it does seem to be universally disliked.

For example, there is not much you could do to Finder to make it worse.

NwtnsMthd··on AI should not replace people at Atlassian, says CEO
That last sentence holds a lot of truth.

Our company has drastically downsized its dependence on Atlassian in the past month, we will be completely free in a few more. With the help of modern AI tools we've been able to replace their products with internal tools that are better tailored to our needs.

NwtnsMthd··on LED lighting undermines visual performance unless supplemented by wider spectra
The flickering is solely a result of cost cutting in the power supplies of these LED lights. The problem is totally solvable with a constant current switching power supply. But the filtering circuitry adds cost.
NwtnsMthd··on Show HN: Circuit Artist – Circuit simulator with propagation animation, rewind
Love the aesthetic, even more, that you published the source! I bought a copy on Steam, thank you for your work!

Any plans to add more advanced campaigns, say, to build up to a simple processor?

NwtnsMthd··on OpenTSLM: Language models that understand time series
This sounds very interesting, would you be able to share a little more about your process? What works and what doesn't?
NwtnsMthd··on Electric cars produce less brake dust pollution than combustion-engine cars
It's a negligible amount, especially if you (or your car) does rev matching. My last car (BMW 328) made it to 300k miles on the original clutch.
NwtnsMthd··on Nuclear reactors a mile underground promise safe, cheap power
There could be a few benefits to what is proposed in the article, here are my semi-educated guesses.

1. Less dependent on local geology. Geothermal wells are well suited for hot, non-pourous (?) geology.

2. Might be cheaper. It can take years to drill the wells for a closed loop system (e.g. Eavor), less for a fracked geothermal well (e.g. Fervo). I imagine drilling a single borehole for this is way simpler.

3. Less water loss. Fracked geothermal well wells can be pretty lossy (20%?). If water supply is an issue your options may be limited.

NwtnsMthd··on How Olympics officials try to catch “motor doping”
200W at 300g is realistic for a modern BLDC motor. The article states that Maxon was the motor supplier so they likely used the EC-4pole series, I'm guessing it's one of these.

It's 30mm diameter to fit in a down-tube, 200W, and 300g. But just because it's 200W doesn't mean you have to run it at maximum capacity, there's no reason you couldn't run it at 5-50W.

Is your server on that list?

j/k, I’m sorry, I’ll see myself out XD

NwtnsMthd··on Carabiner Collection
The Petzl Am'D Ball-Lock[1] is the best locking carabiner I've encountered in the last decade of climbing.

NwtnsMthd··on Understanding a Python Closure Oddity
Do you think you could elaborate on why the results differ? I'm somewhat unfamiliar with how JavaScript works.
NwtnsMthd··on Understanding a Python Closure Oddity
Does this work for user defined classes (objects) as well?
NwtnsMthd··on Better PC cooling with Python and Grafana
Has anyone tried a controller for cooling that is dependent on processor current consumption? Temperature measurements lag, but the current used by the processor is instantaneous and directly converted to heat (P = VI). In theory, it should be possible to reduce temperature spikes.
NwtnsMthd··on Kalman filter from the ground up
A Kalman filter will give you the "best guess" for some state (x) at the current timestep (k). This estimate often has some lag in it, likely because you have some incomplete information that you couldn't model. Sometimes we care about the previous states (e.g., x_k-1). But if we just save these states and refer to them, we're not getting the most out of our data.

The Kalman Smoother can be used to go back and update these past values with all the samples up to the current time. To update your previous measurements, you need to save the state of your filter at every timestep (x_k) and its associated covariance matrix (P_k). You can then apply Kalman Smoothing to reprocess previous data and update it with all current information. This will often remove the phase delay that you would otherwise observe in your estimate.

NwtnsMthd··on Kalman filter from the ground up
We develop navigation instrumentation for directional drilling (oil/gas, geothermal, etc.). In these applications you have to estimate the path of the drilling string based on directional measurements and the length of drill pipe you've put into the ground. To take good measurements you have to stop so that rotation and vibration don't corrupt your measurement.

We use a type of Kalman Filter to estimate direction and instantaneous dynamics of the drill string, this way the drilling operation no longer needs to stop to get a directional measurement.

NwtnsMthd··on Hacking my “smart” toothbrush
No, it doesn't appear so. It seems the bristles do wear out somehow, to me it appears that they simply become less stiff over time. The change to a new brush head is noticeable.

This should be relatively easy to verify. One could take a new brush head and forward its counter to the limit, directly comparing it to a new unmodified brush.

NwtnsMthd··on Optimization Without Derivatives: Prima Fortran Version and Inclusion in SciPy
The optimization libraries in SciPy are surprisingly bad. I've found Mystic to be a great alternative.

NwtnsMthd··on The Legend of Zelda: Tears of the Kingdom Release
Sure, but they probably make the majority of their profit on sales of games.
NwtnsMthd··on Sam Bankman-Fried tries to explain himself

Sums up much of the world we live in :/

NwtnsMthd··on Electric ferry uses a long extension cord [video]
- Can't be jammed

- Simple

- No radio frequency indication of an incoming missile.

There must be other reasons as well.

NwtnsMthd··on Raspberry Pi CEO Talks Pi Inventory, Next-Gen Boards
> "Upton is confident that in less than a year, Raspberry Pi stock levels should return to pre-pandemic levels."

We've long since pivoted away from dependence on Raspberry Pis and back to designing our own custom boards with more available parts.

NwtnsMthd··on I spent a year designing a low profile, minimal mechanical keyboard
I think the rotary knob is cool, despite not having a use for it myself at the moment (I could probably think of one). Is it possible to just reduce the height? Maybe make the knob interchangeable?
NwtnsMthd··on Almost every Ferrari sold since 2005 is being recalled
This may not be such a good choice.

If you turn the ignition all the way off (instead of just the engine) the steering lock may engage. Additionally you will also lose power steering and the brake assist. I guess the latter doesn't matter much in this scenario, but the steering lock could result in a really bad time.
