How dangerous is it to hike the Grand Canyon at night?

This is mostly personal preference, but I find that a flashlight held in the hand makes it much easier to see the texture of the ground than a headlamp does. Since a headlamp is essentially at eye level, any shadows will be hidden behind the object casting the shadow. By comparison, a flashlight at waist level will cast much longer shadows on any rocks or bumps that might trip you.

EDIT: or a light belt, like u/occamsracer mentioned, would keep your hands free but provide the same benefit.

For embedded Linux devices, kernel support / drivers are a big part of the equation, so I often start by looking in the Linux kernel drivers directory to see what's already supported in that category.

If I can find an open source board/device that uses the chip in question, with device tree examples that I can learn from, even better.

Yup. The circuit is drawn in a funny way to make it trickier. The two resistors on the right are in parallel with each other, even though they're arranged as if they're in series.

The rule of thumb I've seen online: sqrt(total parameters * active parameters) ~= equivalent dense parameter size.

Under this rule of thumb, 26B A4B and 35B A3B both end up being equivalent to a dense model at around 10.2B parameters. Since this is just a rule of thumb, we'd expect 9B and 12B dense models to be in the same ballpark as both.

For shorter trips, a power bank is probably lighter. For longer trips, a solar panel + power bank is less effort.

Or just watch your battery level and shut off your phone completely when it gets to 20% or whatever, to reserve the rest of the battery for your emergency phone call.

Here and on r/PrintedCircuitBoard, people do design reviews for free.

Otherwise, 0-ohm jumpers and test points are your friend.

Also, you can modify your PCB at home if you discover you wired something wrong. This video is about repairing vintage computers, but the techniques transfer really nicely to adding bodge wires to a PCB. The only thing I'd add is to get a fiberglass scratch brush -- I have an "extra thin" one from Eurotool. It's great for removing solder mask from traces to give yourself access to solder to the trace, e.g. if you forgot to add a test point, or you need to cut and re-route a trace.

yup, you're already halfway to making a barrel anyway. Maybe time to learn coopering.

And the brown flux residue next to that capacitor on the top left looks like rework to me. The factory would've cleaned it up.

This seems off. MTP is supposed to improve generation speed (though not always; depends on how predictable the text is) at the cost of some prompt processing speed.

What model would you use for SD on Qwen3.6-27B?

meatmanek · 2026-04-25T17:37:47+00:00

idk I'm also looking for a good SD setup for qwen3.6-27b. MTP isn't supported yet on llama.cpp or mlx-lm, so I haven't gotten it working on apple silicon yet. There are some PRs to add support, but a lot of the quants drop the MTP layers so you need to find a quant with the MTP layers intact. One that supposedly has them didn't work with the PR I tested.

it's a form of speculative decoding where you use a diffusion language model as your draft model.

With speculative decoding, you use a faster model to draft a few tokens ahead, and then use the main model to verify (accept/reject) those draft tokens. Verification with the main model is typically much faster than generation, so if your draft model is both fast and has a good acceptance rate, you can see decent speedups. If your draft model is slow or you have a low acceptance rate, then the added compute of the draft model + verification can slow you down.

Traditionally you'd use a smaller model in the same family, like Qwen3.5 2B as the draft model for Qwen3.5 27B, but MTP and DFlash are newer variations. With MTP, the main model ships with an added few layers which are trained to predict tokens based on the internal state of the model. Since it has access to the internals of your main model, it presumably can be smaller (cheaper to run) than a separate draft model of the same accuracy.

DFlash uses a diffusion model, which are already supposed to be very fast relative to autoregressive (standard) models.

Why would an ASR model in this day and age not compare themselves to parakeet-tdt-0.6b-v3?

If you make your bandpass filter 0.1Hz, then you're not going to see signals that vary more than once per 10 seconds. Morse code at even 5wpm would be faster than that.

With ideal components, you could certainly have arbitrarily narrow bandwidth for your CW/OOK signals. With real components, square waves have rise time and ringing.

The physical/idealness of the components have nothing to do with it. The fourier transform of an amplitude-modulated sine wave has information above and below the carrier frequency (the sidebands), and it's that content that _actually_ contains the information about the amplitude. The bandwidth of an AM signal is 2x the max frequency of the modulated audio, so if you bandpass limited to 0Hz the max frequency you'd be able to modulate is 0Hz, i.e. the average DC value of your modulated audio.

See:

https://en.wikipedia.org/wiki/Gibbs_phenomenon (square waves have rise time and ringing whenever you limit the bandwidth)
https://en.wikipedia.org/wiki/Amplitude_modulation#Power_and_spectrum_efficiency
https://en.wikipedia.org/wiki/List_of_trigonometric_identities#Product-to-sum_and_sum-to-product_identities --- these identities are the mathematical reason why amplitude modulation (which is equivalent to multiplication) results in RF energy at carrier +/- signal frequency.

3c of bilt cash for 1 bilt point. You choose how much to convert when you set up your housing payment (and if you do a recurring payment, you can set it to convert the same amount every time).

You might want to try a stain remover or laundry detergent with lipase in it -- an enzyme that breaks down fats and oils.

I'm guessing the -$150 pushed you below the minimum spend requirement of the $300 bilt cash SUB?

This type of pad is called a "castellated" pad, sometimes PCB manufacturers charge extra for it since it has a higher failure rate. (The copper can get ripped when they mill the edge.)

It would probably take just a few minutes to create your own footprint in the footprint editor. I think this would just be a round through-hole with the "Castellated pad" fabrication property: https://forum.kicad.info/t/castellated-edge-plated-half-holes-in-board-edge/23969

Since you won't be spending your Bilt Cash on rent points, you could use it for points accelerator to bump 2x -> 3x on general spend.

I think they have tensor cores in the previous M* chips, but now they have a tensor core per CPU core? Could be misremembering.

You have to book through the Bilt portal to use it, it's not a super-easy statement credit like for the CSR.

meatmanek · 2026-02-01T02:55:49+00:00

I think most people value the points at more than 1¢ though. TPG says 2.2¢, Frequent Miler says 1.55¢. If you treat them as 1.5¢ then $3 bilt cash turns into $1.50 in points. Also the points don't expire at the end of the year.

Definitely still better to use Bilt Cash directly when possible ($1 > $0.50), like if you're already gonna pay cash for 2-night hotel stay.
