  Lisp: It's Not About Macros, It's About Read

Note: the examples here only work with outlet lisp. Refer to your version of lisp/scheme’s documentation for how read works (and possibly other forms) I know it’s an old post by now, but something about the article Why I love Common Lisp and hate Java, part II rubbed me the wrong way. The examples just aren’t that good. The usage of macros is plain baffling, when a function would have been fine. The author admits this, but still does it. There’s a follow-up post wh...

  Sass Style Guide: A Sass Tutorial on How to Write Better CSS Code

Writing consistent and readable CSS that will scale well is a challenging process. Especially when the style sheets are getting larger, more complex, and harder to maintain. One of the tools available to developers to write better CSS are preprocessors. A preprocessor is a program that takes one type of data and converts it to another type of data, and in our case CSS preprocessors are preprocessing languages which are compiled to CSS. There are many CSS preprocessors that front-end develop...

  Backend-as-a-service?

As the list of *-as-a-service’s continues to grow, I thought I’d throw one into the mix. What about the idea of a backend-as-a-service (BaaS)? The recent surge of client side Javascript frameworks along with the attractiveness of simple RESTful APIs has created an environment where server-side interaction can be reduced to simply database interaction (including validation and some computation). But why stop there? What if the server-side of the equation was simply a RESTful, ...

  Get vs Post in HTML form

In HTML, one can specify two different submission methods for a form. The method is specified inside a FORM element, using the METHOD attribute. The difference between METHOD="GET" (the default) and METHOD="POST" is primarily defined in terms of form data encoding. The official recommendations say that "GET" should be used if and only if the form processing is idempotent, which typically means a pure query form. Generally it is advisabl...

  JavaScript as a First Language

At Khan Academy we've been investigating teaching Computer Science to students in some new and interesting ways. The most interesting aspect of which is that we're likely going to be teaching them JavaScript as their first language. We're in a very unique position as we're primarily aiming to teach students who've been through our previous math and science-centric curriculum. Because of this we can create some rather compelling exercises and projects that never would've been feasible other...
