Sometimes the Ethernet port on a Beagle Bone Black does not work on power up. It takes either a physical reset button press or a power cycle to fix it. This problem affects all BBB’s and until now could only be solved with hardware hacks.
The NYC rental market is a deeply broken market. Things like rent control, high switching costs, and crazy tenant protection laws (that horribly hurt good tenants) cause mind bending distortions and completely disrupt the normal supply/demand balance.
If you are new to this market, get ready to learn some new rules.
So today we look inside these amazing cats that can somehow keep on wavin’ using less than 15 microwatts (!) of power. If you are into either ultra low-power or extreme design-for-manufacture, the you will want to see what is inside of these guys!
“What I can not create with an Arduino, I do not understand”, so we then proceed to recreate a lucky cat under Arduino digital control.
You and Nakimoto are stranded on a deserted island with nothing but your notebooks and pencils. Luckily you each have dual PhD’s in cryptography and macroeconomics, so everything is going to be OK – you will survive by your wits alone.
As each year passes and my to-do lists get longer, I have to accept that I will die long before I will get to make and do everything I want to.
Here are some things that I probably will never get to, but maybe you will? Don’t let the crackpot-stream-of-consciousness-style throw you, I believe most of these ideas could actually be successful and profitable… with some work.
Let me know if you are truly interested and I will try to share any effort I’ve already invested to give you a head start….
It doesn’t matter which side of a resistor goes to which connection, and sometimes switching them around can make a board much easier to route. Same goes for equivalent IO pins on a microcontroller and lots of other cases. Here we see what a big difference a little pin swapping can make, and how to give the TopoR auto-router the freedom to swap your pins for you.
There is no intrinsic value to a BitCoin because it is an anonymous IOU written by no one.
I want you to give me half of your doughnut.
I can offer to give you a signed IOU that says “Josh will give the holder of this IOU 1/2 doughnut”. The more you trust that I will actually honor the IOU, the more it is worth to you. You might even be able to trade that IOU to someone else for something that they have and you want… assuming they also think there is some chance that I will honor it.
Instead of writing the IOU, now imagine that I write a program that generates random sequences of letters on my computer. I let that program run for a very, very long time until it happens to generate something like “IOU 1/2 doughnut”. I print this out and I offer to trade it to you for 1/2 your doughnut.
YOU: So if I take this note, someday I can give it back to you and you'll give me something yummy?
ME : Nope. This is not an IOU from me. It was randomly generated by a computer.
YOU: So who owes me the 1/2 a doughnut?
ME : No one! But it took the computer a really long time to generate this note at random!
YOU: If there is no one who will pay me back, then why would I ever accept this note?
ME : You can try to trade it to someone else for something they have and you want!
A dollar is an IOU from the government, a BitCoin is an IOU from no one…
