The point of his hack was to _make_ him a contributor to rails.

I'm aware there are other solutions. Compared to all the work I did to properly tunnel SSH over HTTPS (it was a pretty good firewall, apparently), deploying a node app is trivial.

I would have loved to have this when I worked at a company that only allowed HTTP(S) through the firewall.

How do you figure that knowing the execution path for a basic language feature is an "arcane fact behind the scene?" This is equivalent to not knowing how an if or for statement works. You can't write ANY code without this knowledge.

We pretty much follow all these rules at my company, and it's wonderful. We eat better food than you could ever get delivered and get excellent bonding time out of eating together :)

Most battery management systems incorporate some sort of cell balancing algorithm to make sure cells stay close to a common voltage. Usually this is some sort of resistor (per cell) that dissipates a small current from that cell and bleeds

I start working with these guys in a couple weeks and could not be more excited. Awesome product, awesome team.

I'm not sure about a quick tutorial or "for dummies" sort of thing, but Edward Tufte[1] is quite the expert on this sort of thing. [1] http://www.edwardtufte.com/tufte/

I see, that makes sense. A potentially better (and still simple) algorithm you could use is to take the differences between the cell and the lowest cell, and try to balance to the lowest cell's value. This should give a slightly tighter pac

A Battery Management System contains all the onboard controls necessary for a battery to manage its components. Depending on the complexity of the battery, this includes when to (dis)charge, temperature control, cell balancing, high voltage

Awesome to see something like this out there. A BMS can get very advanced, and it would be very interesting to see a complex open-source system down the road. I'm not sure I understand the balancing code. It looks to me like the gate is tur

They discussed this in the post. They found that the templating was the source of many of the objects, as Ruby creates new objects when performing string concatenation.

Lithium ion batteries can last well over 100,000 miles while still retaining 75% or more of their original capacity. See: Chevy Volt. I'm anxious to see if Tesla can compete in this regard.

I've moved an in-progress project from django to flask, and am loving it. IMO, django has too much boilerplate and requires too much code to get things done. I seem to find myself digging through documentation more than writing code. With f

You don't think other companies are capable of slipping a GPS/3G chip in your vehicle to do the same thing? I don't know what the legality of this would be, but I'm sure they could slide a clause into the pile of documents you sign when buy

I believe dealerships (or the dealership network) are an entirely different corporate entity.

OnStar is a massive advantage for GM; I can't foresee them ever selling it. Edited because my slippery thumbs hit submit early.

Fair enough; how about "your closest certified service center is on Main Street"?

Disclaimer: I work for GM, but do not know much about OnStar, especially internals. My reply is purely speculative. I can't speak as to what OnStar actually does with this data, but I CAN tell you that GM wants to use it as a platform for t

I hit most of the 8 points when I wrote a mobile app in my free time as an intern. It provides remote monitoring of our hybrid battery lab (we staff one shift, test 24/7). It's not a product, per say, but our lead test engineers use it dail

No, this is inspired by that list, with an additional set of constraints.

Now see, I've had the same experience with rubygems on Windows (couldn't find the installer, gem directories weren't where they should be, missing dependencies, etc). It's all a matter of being familiar with your tools. :)

"Package management is somewhat of a hell..." What about it? There's a few packages (mostly C extensions) that don't always build right, but the only problems I've had using pip and virtualenv on Windows have been related to corporate proxi
