Keyword structs, revisited

:: Racket, macros, software

This revises my Keyword structs post to fix some mistakes, discuss the struct* match pattern, and rewrite the macro to use syntax-parse and support default arguments.

A good rule of thumb in Racket is to use a struct instead of list when you’re juggling more than two or three items.

GitHub dropped Pygments

:: Racket, software

My first-ever open source contribution, a couple years ago, was to a project called Pygments. My motivation? GitHub was displaying Racket source code poorly. Pygments didn’t have a Racket lexer. GitHub was using a Scheme lexer for Racket code. The Scheme lexer was highlighting square brackets in red as an “error”. This was really distracting and ugly.

I contributed a new Racket lexer to Pygments, and waited for that to roll into a Pygments release and in turn be deployed on GitHub. Finally Racket code looked good! Later Dave Corbett substantially improved the Racket lexer beyond my small start.

A few days ago, I was confused to see that Racket code was displaying poorly again on GitHub. The square brackets were highlighted in red as errors — again??

Cartoon-me’s thought balloons: WAT, OMFG, FML, &c. Why are we going in circles?

Interview and RacketCon talk

:: software

I haven’t posted here in awhile because I’ve been busy with a variety of things in September, including an interview for IEEE Computer magazine and a talk about Frog at RacketCon. And I’m writing this in Japan.

Someone1 in my Google+ circles posted about Understanding and Using C Pointers, a fairly recent (May, 2013) book by Richard Reese.

Skim or sink

In my experience, the way to become a better programmer is to:

To learn why you should skim this post, please read it carefully.

Host your own web apps?

:: software

In general I’m a big fan of web apps for many reasons:

So great. But obviously the Google Reader shutdown brought me up short. Shook my faith. Am I wrong to prefer web apps?

On reflection, there are two reasons why it’s still OK to prefer web apps.

Frog overview

UPDATE: This was an early post. For up-to-date info, see Frog.

When the code settles down a bit I’ll put it in a GitHub repo, and write a full Meanwhile, here’s an overview.

Live with Frog

:: blog, Frog, Racket, software

OK, I have my site generated using Frog and pushed it to GitHub Pages for

I want to tweak the CSS. It’s vanilla Bootstrap. Most importantly, I wish the headings were a few points smaller and the body text a few points bigger.

The other remaining item is to do the 301 redirect from Blogger to here. It turns out that this should be ridiculously easy to do with Amazon S3. You can make a bucket that does nothing but perform 301 redirects. I’ve created such a bucket already, and the redirects work fine. I simply need to update my DNS, for which I’m using Amazon Route 53.

Lull while I prepare to change tires

:: software, Racket, blog, Frog

I’d been trying to stick to a roughly Tuesday and Thursday schedule for posting here.

I haven’t this week because I’ve been trying to work up a replacement for using Blogger.

Basically, I want to write posts in simple Markdown, and generate the blog statically. To be hosted on GitHub or S3 or whatever. And I want it to use Bootstrap so I don’t have to reinvent that wheel.
