If it is truly facebook only, that eliminates this for me. Too bad.

Looks really interesting. I mainly use C while working on embedded code, how applicable is this book to embedded C?

If this isn't a great resource for embedded C, can anyone recommend a different book?

Tesla Motors

Palo Alto, CA | Full time | Manufacturing Test Engineer

I know most of the job postings here are looking for software positions, but I'm sure there's some people with hardware and test experience as well. Tesla Motors is looking for an experience manufacturing test engineer. We're looking for a generalist, equally comfortable looking at a schematic or at code.

You will be responsible for implementing a PCBA functional tester for a manufacturing environment.

BSEE (MSEE preferred) Thorough knowledge of C/C++ Familiarity with Labwindow CVI, (labview desirable) You should have a good understanding of microprocessors and analog circuits. Knowlege of schematic capture and PCB layout tools (Altium preferred) Knowledge of Java, python, MySQL, C#, and XML desirable,

We're looking for experience with test station deployment, stability, and repeatablity in a manufacturing environment.

Addtional desireable skills: SPC, DOE, NPI, ICT, agilent 3070 basic

Did anyone get an email confirmation after applying for the dev kit? After I hit the button, it reloaded to the home page, and I haven't seen any emails.

Website is a little wonky at the moment. Bear with us guys. We'll get you your kits soon enough.

Just wondering if I should fill it out a second time, since I never saw a confirmation screen. I understand it will take some time to ship, just want to know the application actually made it into the database! :)

Nope... haven't gotten anything yet. :-(

I was taken to a confirmation page that read, "Your developer application has been confirmed. Thanks for your interest in Leap."

The news is hitting me harder than I expected. More than just the products he made, I feel that he directly effected my life. I wouldn't be where I am in my life today, certainly would have the job I have today, if it wasn't for the years I spent at Apple. And I wouldn't have worked there if Steve hadn't first created the company, then later on saved it.

RIP SJ. You certainly changed the world.

This is a fantastic explanation. I've always had trouble "getting" imaginary numbers.... even though I've had to use the fairly often as an Electrical Engineer. This is the first time they've made intuitive sense to me.

^Same here, I have taken countless tests using imaginary numbers, but it never went beyond a really pointless exercise in my mind. Now I get it.

It's a shame I paid for all that college and knowing this would have greatly expanded my understanding of a lot of what I learned in my math classes.

EDIT: I guess I learned it in high school though, and the math teacher probably didn't know this either.

Point being, everyone should come across this at some point. It would be beneficial to many math students.

Back in school, about halfway through my course in DSP, my teacher realized that none of us had any idea what he was talking about...so he went back to basics and explained Imaginary numbers much like this article for a whole day. Things started to make a lot more sense after that, but he was shocked that nobody had taught us that in any of our classes before.

Thanks! I took several college courses using them and didn't "get" the concept until years after I graduated.

Luckily, my AC circuits class was basically the applied version of this article, with lots of conversions between the complex and phase-amplitude descriptions.

What blew my mind at the time was the exponential notation for the unit phasor: e^(i * x). It turns out that e^(i * x) = cos(x) + i * sin(x) because that's just the way the math works out, and it's trivial to work it out yourself by looking at the Taylor series expansions of the three terms.

Pretty cool. The github page has some good information that would be nice to have on domaincli.com (like who's registering the domain, how payment is handled, etc.)

Good point! I'll add that info.

Might still be useful for some embedded applications.

T-shirts were one of the ways that I could tell the culture at Apple was changing.

When I started interning there, there would be a new T-shirt for every new project we would ship. The engineers in my group would all where T-shirts from projects past.

By the time I started full time,and my entire tenure there, the T-shirt culture was over (at least in hardware). Whenever someone would bring it up, or request one for the project we were working on, the answer would be "That's not a priority any more" or "We just don't have the budget for that."

Thankfully the new company I work for has some very cool t-shirts!

This is pretty great. Any idea why it doesn't show prices for driving though? I'd love if I could enter the average MPG of my vehicle, and have it show an estimate of driving costs, so you can compare against flying for shorter trips.

I assume they just haven't gotten around to that yet. The site only launched today, and airfare is the most expensive part of most journeys. Estimating the cost for driving is not too hard and probably on their roadmap. I asked them about it on Twitter and I'm waiting for their reply :)

I'm the co-founder. You're quite right we simply haven't had time to doing this yet. For lengthy car segment we will show the car rental price and petrol costs - for shorter legs an estimate of the taxi fare. The airfare has been our focus for the beta because it's the most expensive segment of the journey, and also the part most commonly booked upfront.
