We built something a bit novel that is focused on composable integration testing in Clojure. We've used this for many years and found it quite useful for keeping a large testing codebase sane.

That has always annoyed me as well, though in fairness the two times they caught a discrepancy at the exit it was in my favor (forgot an item at the checkout in one case, double charged in the other).

Amperity | Seattle, WA | ONSITE & REMOTE | Full-time

Amperity is a startup company founded in January 2016 to tackle the problem of customer data unification at scale.

We are hiring experienced engineers to write Clojure (and ClojureScript for the front end inclined) in Seattle, WA. Remote is an option as well for the right candidate.

This is an early stage opportunity at an ambitious, well funded startup company. Full stack Clojure, not "a bit of Clojure on the side". You'll write Clojure all day, solve difficult problems at very large scale, and get paid.

Background in large scale data processing, distributed systems, and machine learning are all major bonuses. Other elements of the stack include Mesos, Apache Aurora, Finagle, Spark, Kafka, Accumulo, Onyx, SaltStack, and Riemann.

tl;dr This is a series of interactive demonstrations showing off some of Firefox Developer Edition's developer console features, with emphasis on CSS animation.

> Drivers must keep their hands on the steering wheel.

This seems odd, my understanding was that drivers needed to "check in" every so often, not handle the wheel at all times.

They revealed today that the base model has a 90kWh battery, which is currently the top-of-the-line pack size for the Model S. Thus, it's almost certain that the starting point will be north of 90k and very likely over 100k with a few basic options thrown in.

Some early ideas have already hit the repo[1]. David Nolen has been focused on ClojureScript bootstrapping work[2] of late, but I expect he'll get back to Om Next in the coming weeks.

The source code for the post is available[1], as is the macro[2] which is loaded via XHR.

The short of it is that a load function is passed to `cljs/compile-str`, which provides the mapping. In this case, it doesn't bother to do any mapping because it knows that it is loading `bar.core`. However, `bar-url` could instead be in a map from the namespace to the URL. Surprisingly simple, actually!

It's certainly possible that these could be used in combination. GCC optimizations aren't significantly enhanced by JSDoc annotations, so presumably this could generate code for GCC to optimize without losing major benefits on either side.

The React.js team has been explicit about the library being GCC advanced mode compatible, so they certainly have awareness of its capabilities. Whether they are using them together internally or they use a different solution for tree shaking et al is another question.

The two temp solution works, or you can just get rid of the unappealing loose/runny parts of the white by gently rolling the cooked egg over a paper towel. The following chart can be helpful when you're getting started.

IMS Health (Tech & Apps) - Seattle, WA

We're building a global, secure healthcare PaaS using modern technology (Docker, Kafka, Redshift, etc) to enable applications which put our petabytes of unique healthcare data into action.

Looking for pragmatic hackers at various experience levels who are interested in solving hard problems in an entrepreneurial environment. Specific background isn't important, but some exposure to "big data" type things and building service oriented things with modern functional hybrid technologies (C#, Clojure, Scala, etc) is helpful.

Article summary:

Math is hard, buy Mathematica, buy Mathematica, here's a picture of Excel, buy Mathematica, buy Mathematica, math is hard unless you buy Mathematica, buy Mathematica, BUY MATHEMATICA, BUY MATHEMATICA, ... I SAID BUY MATHEMATICA OR MATH WILL BE HARD!!! BUY IT!!! BUY IT NOW!!!

Note that the salesmanship in the summary is a bit more subtle than the actual article.

According to the online calculator, I was in the "acceptable" zone even when I ate a can of tuna virtually every weekday. There are higher levels of mercury in albacore tuna, but generally speaking most people are going to be just fine.
