   There's progress on this front in computer science conferences in software-focused disciplines: http://www.artifact-eval.org/ https://plus.google.com/+JanVitek/posts/19BH96G8rrw The artifact

   In some software-focused conferences, artifact evaluation has become a new, separate phase: http://www.artifact-eval.org/ There is a separate committee charged with evaluating software (and other artifacts, like data sets),

   Thanks for the response! Related to (1), the issue was more that when a _student_ visits an assignment page, they get the same big permission list as an instructor; it makes sense that instructors might need a plethora of permissions. Is

   I use Github in my courses, and I was excited when I saw this. Three responses: 1. The permissions screen immediately irked some of my collaborators – why does this need access to _everything_, including deleting repositories that already

   Off the top of my head, I'm not sure (other than follow-up work to this paper, like http://jeapostrophe.github.io/home/static/icfp065-mccarthy.p... [ICFP '09]). But, the ideas in that paper aren‘t any l

   I'm always really impressed when things just work in Wine. I started using YNAB this year and sure enough, it worked in Wine _with Dropbox integration_. Pretty cool.

   For an approach that does this, check out how Racket's web server manages statelessness across requests: http://docs.racket-lang.org/web-server/stateless.html#%28par... http://cs.brown.edu/~sk&#x2F

    One suggestion is Triplicate ( http://practicaltypography.com/triplicate.html ), which looks _awesome_ at high resolutions.

    This looks like a really great idea. Does Convox provide a convenient way to set up SSL for custom domains? The custom domains page ( https://docs.convox.com/docs/custom-domains ) didn't say much about it, but I ma

    For an interesting dive into one formal definition of the expressiveness of different features, see [1]. It defines expressiveness of features by asking questions like (I'm really simplifying here) "If I add this feature to my la

    Thanks for the feedback. (EDIT: I should note that my only substantial contribution to Racket proper is bug reports and one blog post. I'm mostly just a fanboy.) The load problem definitely doesn't jive with my experience, so I&#

    (I'm a Pyret core designer/developer.) Pyret started its life as a #lang, which was delightful as a prototyping tool. The demands of running with reasonable performance in a browser led us to switch to a direct-to-JS approach, and

    Re the typing point: Statements like "Python is more strongly-typed than Java" can mean too many different things without a precise definition of what "strongly-typed" means. The Wikipedia page linked from the article

    Two things spring to mind, there are lots more I'm sure. Racket's macros are unlike any other. They are better thought of as a lightweight compiler API. Check out http://www.greghendershott.com/fear-of-macros&#x2

    Reminds me of an Asimov story: “But if they have thermonuclear power, where do they conduct the tests and detonations?” “On their own planet, sir.” http://supernovacondensate.net/2012/06/23/isaac-asimov-silly.

    The best thing about this is that there is emulated thread management via setTimeout going on underneath to allow for Ctrl-C and other interactivity while things are running. No background workers, no running things on the server, this is

    Gradual and optional typing have become a pretty big idea over the last 6-7 years, as language designers have tried to retrofit type systems onto languages that weren't designed with them. This idea has been showing up in industry (whe

    Pyret is implemented in JavaScript so we can have a completely in-browser runtime. And since the Pyret compiler is implemented in Pyret, that comes along for free and can be run in the browser as well. JS is far from an ideal compilation

    This worked for the whole first chapter for me (and has some obvious further applications): startLevel["constructor"]("m", "console.log(m);" + "var old = m.placeObject;\n" + "m.

    Thanks for the feedback! There are tradeoffs here, and I appreciate that it's a little glib to say things are necessarily right or wrong. I took down the scope example for now, but in relation to the method example, I posted some tho

    A few things that Pyret gets out of "where" blocks that it's not obvious are easy with just assertions after the function. - Reporting failures can more easily report context about the function being tested - Since "wher
