Byte and Switch (Part 1)

Byte and Switch (Part 1): "Imagine for a minute you have an electromagnet, and a microcontroller, and you want to use the microcontroller to turn the electromagnet on and off. Sounds pretty typical, right?

We ask this question on our interviews of entry-level electrical engineers: what do you put between the microcontroller and the electromagnet?

Stealth Mode: Killer Whales Go Dark to Stalk Prey | LiveScience: ""The two types don't interact, they don't interbreed, they're almost different species in the making," Deecke told LiveScience.

The fish-eating whales are vocal, clicking and calling to each other to echolocate food."

"You're aware that some people think you're a nerd. So what? They're
not players. They've never jousted with Windows or gone hand to hand
with DOS. To them C++ is a decent grade, almost a B - not a language.
They barely exist. Like soldiers or artists, you don't care about the
opinions of civilians. You're building something intricate and fine.
They'll never understand it."

Bird task | ImageCLEF - Image Retrieval in CLEF

Bird task | ImageCLEF - Image Retrieval in CLEF: "he general public as well as professionals like park rangers, ecology consultants, fishers or, of course, the ornithologists themselves might actually be users of an automated bird identifying system, typically in the context of wider initiatives related to ecological surveillance or biodiversity conservation. Using audio records rather than bird pictures is justified by current practices. Birds are actually not easy to photograph as they are most of the time hidden, perched high in a tree or frightened by human presence, whereas audio calls and songs have proved to be easier to collect and much more discriminant.

The Ultimate Developer Event: 4 Keys to Building Better REST APIs

The Ultimate Developer Event: 4 Keys to Building Better REST APIs: ". Use the Correct HTTP Method for Requests
“This is something that took a while to get my head around when I was first getting into this.” explained Lengstorf “Coming from a web development world, I never did a lot of straight HTTP requests. Things like PUT didn’t really make sense. I only understood GET and POST… It is important to take the time and learn the way that they work and make sure that you are implementing them correctly. So that people can actually interact in a way that is proper.”"

My Favorite bash Tips and Tricks | Linux Journal

My Favorite bash Tips and Tricks | Linux Journal: "Command Substitution
Another bash trick I like to use is command substitution. To use command substitution, enclose any command that generates output to standard output inside parentheses and precede the opening parenthesis with a dollar sign, $(command). Command substitution is useful when assigning a value to a variable. This is typical in shell scripts, where a common operation is to assign the date or time to a variable. It also is handy for using the output of one command as an argument to another command. If you want to assign the date to a variable, you can do this:"
