Reducing framerate doesn't help much when there isn't a lot changing between frames. Here are some better optimizations: Noise reduction, so you compress less useless noise: -vf hqdn3d Turn up the Constant Rate Factor. This wil

Classic parallel (ATA, PCI, parallel ports) is going away and not really coming back. The newer interfaces like 4xPCIe and USB are multiple serial interfaces bonded together. The difference is all the bits in a true parallel interface oper

Subcompacts sold today are much larger and heavier than what they used to be. Here are the lightest cars I could find for sale in North America in 2024 in 15 minutes of searching: Honda Fit 1,070–1,280 kg (2,359–2,822 lb) Mazda Mi

They're not telling us, so I'm assuming what's required for a very small, efficient car. It could easily be 50-100% more than that.

1km/s on a 1000km pack is a 3.6C charge rate. That's fast but not jaw dropping. Guessing it's a 100kWh pack, that's a 360kW charge rate, which is somewhat more than the 250kW Superchargers currently supply. I think the

I create wrapper scripts. I try to keep them simple... they're convenience scripts, not a replacement for a build system. Here's one for a QEMU dev env where I add and remove bits of command line in a freeform way. I just break

Mine consistently produces better rice than my old mechanical one. It's also slower. I think it does a more gentle temperature ramp than the mechanical one did.

Mars Pathfinder did exactly this. It was a tetrahedron which could land in any orientation. As it happened they rolled a 4, but if it was on one of the other 3 sides it would have pushed itself upright as the sides folded open. https:&#x

Yep! About 15 years ago I decided I didn't like what alcohol did to people around me and I haven't had a drink since.

Ben over at Applied Science did a great video of his quest to build an analog bite sensor for a musician. It would be easy to adapt it to work as a TIG controller. https://www.youtube.com/watch?v=ag_p8gayrTs

It's a piece of cake. BLE doesn't try to hide anything. Install "nRF Connect" on a mobile device and have fun.

My personal peeve: $ git log directory --stat fatal: option '--stat' must come before non-option arguments Come on, Git, you know what I want. Just do it without making me repeatedly edit the middle of the command.

FFTW [1] does something like this, not just for parallelism but also for selecting optimal algorithms for a given data set and architecture. It uses "wisdom" to store known-good combinations, falling back on quick heuristics and

Something like this: https://www.amazon.com/dp/B007CZ6PD2 I just noticed that you're using a mains-powered pump, so don't splice its wires directly. Instead, insert the float switch on one of the wires betw

I love ESPHome. The declarative language makes it fun and easy to do so many little tasks like this. Used with Home Assistant it makes it easy to create graphs of everything. Do I NEED to know how much water my tree consumes? No, but I

You don't pull all of the control rods at the same time. You can fully withdraw some number of them, then control the reaction with a few more rods. There are several strategies to provide additional control so it's not all at th

I suggest adjusting your gradient so they don't fully fade out until just before the sweep hits them, or maybe even only down to 10%, so they only get wiped by the bar. It'll make it much easier to watch a plane if it doesn'

If the write-cache is reordering requests (and it does, that's the whole point), you can't guarantee that $milliseconds will be enough unless you stop all requests, wait $milliseconds, write your commit record, wait $milliseconds,

In my opinion, if you asked for --help, the help IS the program's output, and should go to STDOUT. Unsolicited help messages for incorrect command lines ought to go to STDERR. It's especially frustrating for programs which only w

One of the niftiest ways I've seen this done was some software I used circa 2000 (I don't remember the name). It would create a variable-rate timelapse by saving a frame every time the image changed more than $x percent, calculat

I'd say a type which doesn't have both a significand and an exponent isn't a float at all. How can you have a floating point with no ability to move the point? To have something IEEE754-like you'd need a sign, significa

Torque is directly proportional to radius, all other factors being equal. There are practical limits on the strength of the magnetic force because you can only cram so many amps through a confined space, which is even more confined on a sm
