But we can simplify this.
I'm not putting finished effects into standalone metal #boxes at this point; I'm #experimenting, not producing a product. So I have a simple #modular system I cooked up to connect arbitrary effects #experiments together. One of the things it does is handle the power-supply stuff, so each effect board doesn't need to do any of that. It just receives a nice 0V and buffered #Vcc (9V) it can rely on, along with a buffered 4.5V to use as a #bias voltage when AC coupling #signals, since this is a single-supply system.
So we can chop out all the power stuff from the schematic, which fills basically a ninth of the image - divide it into 3 rows and 3 columns, like the Brady Bunch intro, and the left-middle square is basically the power section.
But there's a bigger chunk we can strip out. Boss (and many other) pedals of the era frequently used "soft switching" to enable / disable the effect while playing. If you go back in time, real physical #switches were used, so the signal was actually totally disconnected from the effects circuitry when in the "off" position. This is called "true #bypass", as opposed to the soft switching.
#Soft #switching involves having two signal paths through the effect. One applies the characteristic effect, and the other basically just buffers the signal and bypasses the rest of the effect stuff. This is implemented with transistors and latches.

When designing a scientific experiment, a key factor is the sample size to be used for the results of the experiment to be meaningful.
How many cells do I need to measure? How many people do I interview? How many patients do I try my new drug on?
This is of great importance especially for quantitative studies, where we use statistics to determine whether a treatment or condition has an effect. Indeed, when we test a drug on a (small) number of patients, we do so in the hope our results can generalise to any patient because it would be impossible to test it on everyone.
The solution is to perform a "power analysis", a calculation that tells us whether given our experimental design, the statistical test we are using is able to see an effect of a certain magnitude, if that effect is really there. In other words, this is something that tells us whether the experiment we're planning to do could give us meaningful results.
But, as I said, in order to do a power analysis we need to decide what size of effect we would like to see. So... do scientists actually do that?
We explored this question in the context of the chronic variable stress literature.
We found that only a few studies give a clear justification for the sample size used, and in those that do, only a very small fraction used a biologically meaningful effect size as part of the sample size calculation. We discuss challenges around identifying a biologically meaningful effect size and ways to overcome them.

Fascinating. I had never even heard of this (but maybe I was lucky to be a little younger)]

Wow. Wow. Wow. Thank you @grimalkina, Lizzie, Liz, and Jennifer. More Leaders need to listen in to this fantastic panel discussion about the value of developer experience. #platform #productivity #experiments #metrics #roi

Though familiar features of our skies, #clouds are surprisingly elusive. Last night, in a highly anticipated public lecture at Feldstraßenbunker in #Hamburg, our director Bjorn Stevens set out to explore and address some of the fundamental questions driving scientific research on clouds. A particular highlight of the talk was a series of engaging #experiments that demonstrated the physical processes behind cloud formation. Someone may have gotten wet!

Fifteen minutes with an old friend, a wheeled dog I was given by an old friend of my Dad's, when I was a little girl.
I'm continuing my experiments with the Ecoline Brush Pens, not sure whether I like them or not, but they do cover the ground, as it were!

Weather and Climate Experiments by Pamela Walker, 2009
Study of the weather and climate helps students understand weather conditions and the science behind weather research. Temperature, barometric pressure, wind, and precipitation are just a few of the types of data routinely collected and analyzed by meteorologists.

Experimented yesterday with Fedora’s KDE spin… I was shocked by the level of accessibility, although it wasn’t perfect. My primary issues with it were that I had to use a lot of Orca’s navigation commands to read panels in the systems settings app, and I had major issues with Konsole, the default terminal app. I wasn’t able to read any of the information in that particular apps interface using Orca. I also tried the Fedora workstation edition, which uses Gnome as it’s a desktop environment. Let’s just say that was not worth my time. Had accessibility issues there as well, and surprisingly it was worse than the experience I had with KDE. I know KDE defaults to Wayland, as does Gnome, but KDE’s accessibility implementation seems to be a lot better than what Gnome has under Wayland, with the exceptions I’ve previously mentioned. Incidentally, the X 11 experience with Gnome is actually worse now than it was previously. For example, the terminal app does not even open for me. I should also note that all this is under Fedora 41, so people aren’t confused. #A11Y #Accessibility #Blind #Experiments #Linux #Fedora41 #KDePlasma #Gnome #Wayland #X11
Well, sweet potato bread, attempt one, wherein I failed the basic rule of experiments; write down what you did. But I’m not sure how you could actually make a foolproof recipe because each potato is going to be different in texture and wetness, so you kinda just have to do it by feel. Anyway, this one was 1 large roasted, peeled and smushed sweet potato, about 3 cups of high protein flour, 2.5 tsp yeast, 1 tsp fine grain salt, 1 tablespoon raw sugar. About 7 oz of warm water, added an ounce or so at a time. 1st rise, an hour, second rise about 45 minutes, bake 425f for 25ish minutes to internal temp of 210f.
Changes I would make, longer second rise, lower temp to 400 and bake a little longer, or sheild the top at 425.
