HUGE phalaenopsis orchid flowers. The petals are round and they have pinkish-purple polka dots

Please look at this GIANT beautiful orchid that is flowering in my kitchen right now.

Has anyone built an installable ARM64 Windows version of Darktable? Or at least a simpler set of instructions for building your own? I am having trouble getting it to compile myself.

"He's starting to believe..."

I haven't done any reading about how this can impact human perception. Slow and drastic enough variation has obvious effects, like a strobe light, but what about pulsing 60-100% brightness at 60Hz? It isn't visible to me like CRT 60Hz 0-100% flicker, but it certainly ain't nothin'.

The same setup cropped to show the screen showing noise

A USB lamp, which is electrically isolated from the local mains frequency, was quite noisy. I didn't look to see if this was actually significant next to the light level, so maybe this is just a magnified whisper of noise.

The same setup cropped to show the screen showing a vaguely sinusoidal signal with lots of higher frequency noise in the signal

My Phillips Hue variable color temperature bulbs were shockingly noisy.

The same setup cropped to show the screen showing fairly noisy sinusoidal ripple

The same setup cropped to show the screen showing rather clean sinusoidal ripple

The same setup cropped to show the screen showing fairly clean triangular ripple

Most of the mains-driven LED lights in my house have 60Hz variation (ripple) on top of a consistent base illumination. The higher quality ones tend towards sinusoidal ripple and the cheaper towards triangle waves, though even the cheapest were fairly clean.

The graph is a sparkline, so it shows local variation but not absolute value. I had it printing some other data on an attached PC, but I wasn't watching that very closely.

A small IoT dev board with an onboard LCD screen wired to a small red circuitboard bearing a phototransistor. The screen shows a triangle wave.

I managed to slap something together. This is a little IoT board I had lying around wired to a phototransistor tuned to the visible spectrum.

Love me some Rock of Chickamauga.

In the same sample we saw a large fraction of Pompano, another ocean fish.

I really thought we had mixed up with a Hawaiian sample.

Every version of individual meritocracy elitism will, at the end of the day, not care about you. You don't really get saved from it all by thinking you made it to the special class that gets to be intellectual or whatever. All we can do is try to find ways to care about each other.

For years, I have have said that legal documents are written in a Domain Specific Language which vaguely resembles English, however it should never, ever be confused with the language we call "English".

Similar to how COBOL is a DSL which also resembles English.

Ah yes, my discrete math teacher had a related term. For some proofs he invoked the ROOTH method--Rabbit Out Of The Hat.

HI ALL!👋 We heard that the sky is bluer here so we thought we’d come over and take a look!

A two page panel from the webcomic Phantomarine. The crew looks down a watery passage. Cal: Oh, it's probably just the tides beginning to... They see a pink orb coming toward them with a splash. Cal: ...Ah! No. Something IS coming this way.

Phantomarine is updated! Ch 7 p 43

Ah. My mistake.

(Mary's post just reminded me)

Time to dust off my annual "no really, you can just read the telemetry yourself" reminder!

Ofc, I don't search Alibab that often...

If I do it it'll go up on Hackaday.io, but be prepared for that key Sparkfun part to be 6 years old and not easily swapped out for your own version.

(And I might pick a painful software stack for fun, it's happened before...)

Because yeah, commercialization is HARD

Black-and-white photo of two kittens sitting side-by-side. One is a medium haired black tuxedo. The other is medium haired white with darker patches and wearing a ribbon bow around its neck. Text at the bottom of the photo says “engaged“.

Engaged! Postcard from my collection, no date.

ADHD willing, I will 😭

One day I'll build the light meter I want to quantify spectra and flicker...

UV LED->phosphor to get white? OK to be fairly bright, this is how fluorescent works already but seems better crafted, not having to work around plasma physics.

RGB for white? OK for mood lighting etc. but high prescription glasses come with high dispersion and so harsh rainbows.

PWM driven: depends on the frequency. The cheap ones have 90% duty cycle at 120Hz, the really cheap ones 60Hz--the flicker bugs me. Just use a ding dang rectifier and filter!

There's a bunch of misinformation on here about the regime's Medicare durable medical equipment provider announcement today

Yes, my sister got hit with something similar (same?) and it was global MSA logout that finally let her start cleanup.

Since expertise and learning is so massively important in this era but we haven't career pathed that in tech or built the structures for those people to be included, what if software engineering organizations had Learning Scientists in Residence. How fun would that be.
