Chicken Scratches: Developing ideas on developing.

Some Programming Language Limericks

March 2nd, 2016 by Eddie Sullivan
If size and performance are key
And you’re happy with malloc and free,
If you’re one of the masses
Who disdain to write classes,
It’s time to start coding in C.

For recursing through various entities
Or traversing a forest of data trees,
I’d say Lisp is the one
For your programming fun,
If by fun you mean lots of parentheses.

I cut back on my usage of braces,
Threw out my selects and my cases.
I was feeling dynamic!
But I started to panic
When I learn of significant spaces.

Oh Java, I’m not being snarky,
But tell me, what is this malarky?
Thought my head would explode
When I looked at the code
And saw pages of class hier-ARCHy.

I know an intelligent girl.
On the keyboard her fingertips twirl.
Soon brackets and slashes
Meet dots bangs and hashes
As she writes her next program in Perl.

They say, “JavaScript’s really quite good.”
That it’s functional under the hood.
That for every mistake
That’s too easy to make,
There’s a “good part” that’s misunderstood.

It gave all our spirits a lift
When Apple unveiled a new gift.
With inferring of types
And bit too much hype
So launches the era of Swift.

C++ for its time was quite neat
As a tool for the coding elite,
But I started to doubt
On the day I found out
That its templates are Turing complete.

The mixing of content and code
Has proven a dangerous road.
And those who agree
All blame PHP
When pages take ages to load.


It’s not universal as yet,
But everyone fancies .NET.
Since we all can agree
That it’s sharper than C.
For MS it’s the best you can get.


If you’re looking to program .NET
F# is the language to get.
I once read about LINQ —
It’s quite useful I think,
Though the syntax I sometimes forget.

We’re studying SQL
To save us from database Hell,
And when we speak we’ll
Pronounce it sequel.
(Though spelling it works as well.)

Try making your website come alive
By learning some HTML5!
With new tags galore,
New effects and more,
The future is soon* to arrive!

10 It was back in the days of my youth
20 ‘fore I knew that GOTO was uncouth.
25 I learned how to program
26 With BASIC and FORTRAN.
30 (Not the prettiest code, it’s the truth.)

With all that a website entails
I thought I’d try Ruby on Rails.
The code, it all works,
But the folks were such jerks
I decided to hit the trails.

Objective C, Objective C,
Without you, oh where would we be?
Your syntax is old
(Too verbose we’ve been told)
But as clear as a language can be.


If you’re praising Objective C
I’m afraid that I must disagree.
Those gosh darn brackets!
They’re like straight jackets.
They litter the code like debris.

So Google has come out with Go
Is it good? Well I really don’t know.
It’s another arbitrary
Language proprietary,
To be cancelled before it can grow.

Speaking of cancelling projects
Angular lands with the rejects.
“We’ll support version 2!
And we swear that it’s true!
We’d never be evil at Googleplex.”


Remember the promise of Flash
Before it turned out to be trash?
With too many updates,
With adverts and clickbaits,
And bugs that would cause it to crash.

In the low-level language family
You can never exceed assembly.
It’s lightning fast —
I’d say unsurpassed,
Though not very user friendly.

Some programmers back in the day
Used COBOL, I’m sorry to say.
Two digits per year
Was awfully severe:
It left us with Y2K.

It seemed so simple to request
To center text with CSS.
Left-to-right went okay,
But oh dear! I must say
Up-and-down was a terrible mess.

So Pascal, yes I vaguely recall
From a course that I studied one Fall.
Fell asleep in the lecture,
Which makes it conjecture
To remember the language at all.

Welcome to Emoji World

February 23rd, 2016 by Eddie Sullivan

Welcome to Emoji World.

The age of texting brings with it its own language and culture. It has been pointed out that the current time period is the first in which we have real-time written communication. Add to that the limited input methods we’re forced to use, and it’s no wonder a new vernacular has developed.

To overcome the limitations of textual communication without requiring impractical verbosity, we have resorted to emoticons, abbreviations, and now emoji.

On Coders and Programmers

February 15th, 2016 by Eddie Sullivan

“Words words words” –Shakespeare


Once I was a programmer. I became one by learning BASIC, then QuickBasic, then C, then C++, and so on. Hours of copying code from magazines, scratching programs into a notebook with a pencil, solving problems, falling in love with ideas. I wrote programs. I programmed. I was a programmer.

I studied hard and eventually became a Software Engineer. I worked hard and became a Senior Software Engineer (with a brief detour as “Member of Technical Staff” at a new-fangled startup). Now I run my own company so I’m whatever the hell I choose to call myself. One thing I’m not, and have never been, is a coder.

Seven Deadly Annoyances of API Design

January 25th, 2016 by Eddie Sullivan

Designing an API is an art and a science. Many intelligent people have failed. Those who succeed do so by keeping in view the main goal of an API: to annoy the hell out of developers.

My brothers and sisters, to honor that noble-ish pursuit we gather together to enumerate (see what I did there) the Seven Deadly Annoyances of API design. I never thought I’d write a listicle, but at least it has an erudite religious reference in the title.

First, a couple rules: We’re talking about successful, working APIs here. So things like “it doesn’t work” or “it opens a massive security hole” don’t count as annoyances. Don’t take the word “deadly” literally. And APIs that no one uses are not qualified. No, failed APIs are not annoying, just bad. Here we discuss just the minor things. The minor, hair-pulling, keyboard-smashing, Urban-Dictionary-quoting annoyances we all know and despise.

Many of the examples come from Android, because that’s who most recently has the pleasure of annoying me, but I don’t mean to pick on them. They have no monopoly on these sins.

Annoyance the first – trsnss

Yes, name-ification of things is hard. Still, common sense could go a long way. You gotta hand it to the Unix folks for their heroic efforts to save a keystroke – why say dupe when we can save that valuable E and say dup?

The Multi-platform Developer

December 8th, 2015 by Eddie Sullivan

Which Tool Will You Use?

In my career, I’ve developed professionally in Python, Java, Objective C, Swift, C#, C, Assembly, C++, TCL, Perl, JavaScript, PHP, Scheme, Racket, Haxe, ActionScript, Lua, and more. I love them all, and I love switching between them – I enjoy seeing the subtle nuances of language design. It’s almost like a window into the mind of the designer. Some might say that career-wise, it would be better to specialize in one language. Often the phrase “Jack of All Trades” is followed up derisively with “Master of None.” Obviously I disagree, and here’s why.

When someone asks me what type of development I do, I say “all types.” Sometimes they nod and move on because they’re just making conversation. Others will probe deeper and ask about programming languages. I say “all of them.” That is clearly hyperbole, but in a very real sense, I mean it. Or rather, I mean the opposite.

What language do I develop in? None of them. You might as well ask, “In what language did Plato philosophize?” Well, he spoke and wrote in ancient Greek, but his ideas make just as much sense to those of us who don’t know a word of Greek. The ideas are universal; the language is the medium to communicate those ideas. Likewise, programming concepts are universal and the programming language is the (often clunky) means to communicate – to fellow developers and to the machine.

And yet… And yet, it’s not so simple, is it?

Guitarator Toolbox now available for Mac OS X!

November 4th, 2015 by Eddie Sullivan


Ever since the PC version of Guitarator Toolbox came out several years ago, folks have been asking me when there would be a Mac version available. Well, it’s been a while, but I think will be worth the wait. I’m proud to announce that Guitarator Toolbox is now available for purchase in the Mac App Store!

Thanks to those who tried the Beta version and gave me valuable feedback.

This version is for Mac only and requires at least OS X version 10.7 (Lion).

What is Guitarator Toolbox?

It is a desktop application, originally written for PC, but NOW available for Mac, with the following features:

  • Look up how to play any chord you can think of in any tuning for your guitar, bass, or other stringed fretted instrument.
  • Look up how to play lots of different scales.
  • Perform a “reverse chord lookup” where you pick the frets and it tells you the name of the chord.
  • NEW: Metronome.
  • NEW: Chromatic Tuner.

Introducing the Chorderator Android App

February 12th, 2013 by Eddie Sullivan

In response to many requests, I have created an Android App version of my popular Chorderator guitar chord lookup tool. This is a quick app that lets you look up any guitar chord you can think up, in any tuning. Many tunings come preprogrammed, including guitar standard, dropped D, mandolin,bass guitar, and banjo. Or you can add your own custom tunings. You can listen to each chord shape.

And NEW to the Android App, you can batch up a collection of chords into “Chord Sheets.” So, for example, if you’re learning a song you can save all the chords for that song into a sheet, which you can share by email or text message.

The App is completely free while it is in its Beta stage. Eventually there will be a free version and a pay version. For now, why not head on over to the Google Play Store and give it a download!

Eddie’s Django Tip #4: Stay Up to Date

July 22nd, 2011 by Eddie Sullivan

The Persistence of Memory

By some measures, Django is still shiny and new. Originally created in 2003, it’s newer than my car. A house built that year would be considered pretty much fresh from the oven. A baby born in ’03 would be just entering sixth grade now. But by Internet time, it’s been around practically forever. Especially because Django has been under constant development for that whole time.

The fundamental concepts and philosophy of Django have not changed much, but there have been significant features added and modifications made to the way many components work. This is especially noticeable to those of us who have been using it since its early beta days. While I didn’t agree with every change as it was made (auto-escaping in templates, for example), in general Django has clearly been getting steadily better.


Eddie’s Django Tip #3: Don’t Mix Your Media

May 17th, 2011 by Eddie Sullivan

Don’t mix user-uploaded content with site-specific content with Django admin content.

This is a simple one, but I have seen projects where this was not followed, and the result was a real mess. so please, please, please do not mix your media!

There are (at least) three types of content that we can think of as “media” in a Django project: There is the Django admin media – the CSS files, images, and JavaScript that come with Django itself for use in the admin interface. Then there is your own static media that you use to style your site. And finally, there is user-uploaded content – things like profile pictures and so on. I recently took over a project where all three were in the same directory. I nearly wept.
