johnpmayer··on Elnode, the EmacsLisp webserver, nears release
Just a suggestion, but I think a video tutorial demonstrating the workflow advantages would be incredible for the visibility of the project. I, for one, would like to see how you envisioned elnode as a self-contained productive development and administration environment within emacs.

edit: doh this is planned

johnpmayer··on Elnode, the EmacsLisp webserver, nears release
Sorry, what exactly makes it "not a real lisp"? Maybe that statement is out of date, considering the addition of lexical scoping in Emacs 2.4.

Regardless, it seems like the author is able to build some real things. I know, for example, that you can run a simple file-directory server using elnode.

johnpmayer··on Haskell Live: A Live Coding Adventure
While certainly anecdotal, I attribute 99% of my opengl knowledge to the extremely comprehensive WebGL 101 videos by emoller. The video was two hours long, but it took me about 8 to get through as I copied code, made changes I liked, and made sure it compiled at each milestone.

Of course, opengl/webgl isn't a language, and the hand-holding might be more necessary.

Finally, all of his code (each finished milestone, of which there were at least a dozen) was available on github.

johnpmayer··on Divide a number by 3 without using * / + - % operators

  for i... {
    append i
    append i + 0.333
    append i + 0.666

johnpmayer··on Natural Gas Fracking Industry May Be Paying Off Scientists
He means as opposed to having foreign researchers putting out the claims, who could conceivable have less of an ethics barrier, since it's "not their land".

Still agree with you though - pretty shameful if true.

johnpmayer··on Google is slowly cracking "open" iOS
This is what I thought. Somebody in Congress should hire another Princeton professor for a few million to figure out if a browser is, in fact, a crucial piece of a mobile operating system. After grueling research, I bet I can predict the answer to that.
johnpmayer··on Citus Data (YC S11) Wants To Make Scalable Data Analytics Accessible To Anyone
This sounds a lot like AsterData Database, which I know has been around for at least a few years. I'm interested to know if you are able to write queries that define explicit parallelism like in the SQL-MapReduce language extension, and also the ability of the query preprocessor for the distributed workload.
johnpmayer··on The fanless heatsink: Silent, dust-immune, and almost ready for prime time
I'm somewhat confused; do demonstrate how quiet it is, they turn off the loud motor that keeps it running?
johnpmayer··on Build your very own submarine starting from $50,000
Reading through the specs, it seems that it's designed with that in mind - the center of mass is much lower than the center of buoyancy.
johnpmayer··on Famous judge spikes Apple-Google case, calls patent system “dysfunctional”
Depends on your definition.

In my interpretation, to be considered a line in any number of dimensions, it must be specified by no fewer than two points. This puts a lower bound on the amount of information to specify "lines", a bound strictly greater than specifying a "point" in a space of similar dimensions. Otherwise, is point also a polygon consisting entirely of zero-length sides?

But anyway, I think it was only meant to highlight the Judge's opinion of the absurdity of some claims.

edit: so glad this tiny portion was the subject of the most discussion

johnpmayer··on 100x better approach to software?
But that's maybe not the best example; wasn't it originally just him? I think GNU+Linux might better demonstrate what you're trying to say.

johnpmayer··on Go version 1 is released
With interfaces, it's pretty simple to replicate patterns like a Container<Comparable> or Channel<Reader>, to borrow common Java syntax. Personally, I like how it forces you to think about parametricity whenever you want polymorphism, like most functional languages.
johnpmayer··on GitHub for Mac 1.2: Snow Octocat
I use it for importing repositories, and sometimes as a historical diff tool, but usually not for commits. Looking forward to updating.
