I write the open-source photo editor Filmulator as a hobby.

I'm also the lead software dev on the PhobGCC hall-effect motherboard for Gamecube controllers.

I find the color criteria for Cosmic Crisps seems to work for Honeycrisps too. But good Cosmics are more consistently available.

I think Beta's CTOL has better economic prospects, if less useful as an air taxi.

The hammer is felt around wood. You don't replace the felt, you'd replace the entire hammer, but then you'd likely want to replace all the hammers to get matching sound anyway.

There's a solution you can add to soften the hammers, but I don't know what chemical it is or how well it works since I haven't tried it yet; you can also needle the felt to fluff it up.

I've done some DIY piano maintenance and I saw what was presumably this available to firm up the hammers. My piano needs them softened, though.

Heh, I upvoted this a few days ago and it must've gotten on the second-chance queue.

It's $200 cheaper than that for that configuration with Linux instead, only $2100.

Rigid = premium-feeling

Strong = won't break

My Framework 13 is robust but isn't the most rigid-feeling. If I one-hand hold the laptop by the front edge it presses the touchpad clicker.

> My one concern is that their CPU options top out at 4 performance cores; the i7-1370P I have right now has 6.

I was looking at benchmark comparisons between my i5-1240P which has 4 performance cores and 8 efficiency cores, and the Ultra 5 325 which has 4 performance cores and 4 low-cache ultra low power efficiency cores.

The 325 is still faster multicore than the 1240P.

CarVac··on The purist's guide to phở in Hanoi
I've never been to Vietnam but there's a Hanoi-style pho place by me and it is head and shoulders better than any other pho I've ever had in the US.

Apparently most pho in the US is southern Vietnamese style?

CarVac··on A database of analog cameras that can be 3D printed
I have an abomination that I printed years ago that adapts an Instax SQ1 to Hasselblad lenses (and has an RB67 focusing screen on a viewfinder next to the Instax for composing and focusing).

It's sooooo impractical but the results are so fun.

The process is to compose, focus, put ND filter on, swap from finder to film body, half-fire the shutter, pull out the dark slide, fully fire the shutter, push in the dark slide, eject the film, rewind the shutter, and go back to the finder.

Yeah, the default is alright with perhaps a little exposure adjustment.

Bump the drama and lower the white clipping point a little if you want a bit more local contrast.

I need to fix Phase One support in Filmulator. LibRaw has some additional processing steps required that I didn't manage to figure out last time I worked on it.

I'm always glad to hear that people are enjoying Filmulator. I don't track downloads or anything so I have no idea how many people out there use it.
CarVac··on I quit editing photos
It really depends on the person.

I do not take photos for the memories, I take photos for art and I do go back and look at them.

Yes, it properly supports monochrome DNG and disables (and hides) tools that are not applicable such as demosaicing, CA correction, highlight recovery, white balance, etc.

I didn't know such firmware hacking was available. I'd been waiting for the GR Monochrome for years but it's a bit expensive for me.

It's not GPU-native… that's a goal but it'll certainly take some time. Back when I was last working heavily on it there commonly wasn't enough vram but now there should be on most machines.

33 megapixels is not a lot. I'd consider that fast on my 9800X3D gaming machine but moderate on my older 2700X dev machine. But of course, what you consider fast depends on your computer and your expectations.

Zooming and panning is much faster on Filmulator than most other software because it caches full-res images throughout much of the pipeline. On my gaming monitor I can rapidly zoom in and out at a buttery-smooth 240Hz refresh rate.

But actually changing settings is a bit slower.

The earliest settings are the slowest to respond since they only operate on full resolution raw data, but they're non-creative, technical decisions on highlight recovery and demosaicing and such that do not need tweaking. Additionally, you get early feedback from these in the form of early-pipeline histograms interspersed among the tools, helping you tune these settings quickly.

Noise reduction adds a lot of processing time but once you figure that out the full-res image gets cached and doesn't interfere with later steps.

It has fast (~100ms) screen-resolution response to sliders in the filmulation tools mid-pipeline but it'll take a second or two for the full resolution image to process.

Late pipeline editing (post-filmulation) is near instant even for the full resolution.

So is it fast? Yes and no. But it tries to always be responsive and provide useful information as quickly as possible.

I got tired of in depth fiddly editing and wrote Filmulator to minimize the decision-making and streamline editing. I rarely spend more than 20-30 seconds per image.

You get a clean, basic look, no weird colors or overly creative "looks", but with adjustability and great highlight handling that JPEG doesn't get you.

The current builds there are quite old but we've got new ones coming.
