Basics: Picking Resistors for LEDs | Evil Mad Scientist Laboratories
"So… you just want to light up an LED. What resistor should you use?
"Maybe you know the answer, or maybe everyone already assumes that you should know how to get to the answer.  And in any case, it’s a question that tends to generate more questions before you actually can get an answer: What kind of LED are you using? What power supply? Battery? Plug-in? Part of a larger circuit? Series? Parallel?"

LED Current Limiting Resistors - SparkFun Electronics
Use resistors with your breadboarded LEDs, the way the cool kids do.
"Limiting current into an LED is very important. An LED behaves very differently to a resistor in circuit. Resistors behave linearly according to Ohm's law: V = IR. For example, increase the voltage across a resistor, the current will increase proportionally, as long as the resistor's value stays the same. Simple enough. LEDs do not behave in this way. They behave as a diode with a characteristic I-V curve that is different than a resistor.
"For example, there is a specification for diodes called the characteristic (or recommended) forward voltage (usually between 1.5-4V for LEDs). You must reach the characteristic forward voltage to turn 'on' the diode or LED, but as you exceed the characteristic forward voltage, the LED's resistance quickly drops off. Therefore, the LED will begin to draw a bunch of current and in some cases, burn out. A resistor is used in series with the LED to keep the current at a specific level called the characteristic (or recommended) forward current."

Gaia Bees | A new approach to living with bees
"Gaia Bees was founded to honor the essential role of bees in sustaining life on our planet. Our mission is to ensure the health and survival of bees, and thus, all beings.  Gaia Bees advocates for a fundamental shift in apiculture and develops new practices toward a bee-centric approach.
Our work focuses on three areas: installation and care of “landscape apiaries”; research and development of sustainable apiculture strategies; offering educational/training programs."
Per Erik Knutzen, who absorbed a paradigm of honey bees colonies as superorganisms from Gaia Bees' Michael Thiele.

Everlane | Modern Basics. Radical Transparency.
Silicon Valley's favorite couturier, per the "New York Times." Apparently the appeal is that these clothes are the fashion uniform one wears to show that one pays no attention to fashion. My Warby Parker bookmark notes begin to explain my mixed feelings about what this means. Beyond the irony cited above, I suggest that this urge to look like nobody, like part of the background, emulates an anti-style established by the socially awkward who fear this entire domain and refuse to engage in it. We haven't all been there, but I have. But you can't have any curiosity, or powers of observation, and STAY there. There are things out there that work better for you. There are things that are more comfortable, or more durable, or easier to care for. If you can't tell any of these differences yet, stick around. You will. When that happens, you can make your OWN style, and it will be something different from NO style.
