Eric Sink on the Business of Software. Eric Sink. Apress (Book Review)

Eric Sink on the Business of Software is a selection of Eric’s essays from his website and blog. He explores the business concerns that programmers face in small software development shops and starting out on their own. Note: much of the material in this book is available online.

This relaxed, easy to read and sometimes offbeat book is a candid recollection of Eric’s successes and failures in starting his own Independent Software Vendor (ISV), SourceGear. Eric founded SourceGear, in his own words, “somewhat by accident”, and he relates the joys and pitfalls he experienced along the path of starting your own ISV.

I have read Eric’s blog for several years, and I have always enjoyed his insights and commentary on a diverse range of subject matter, usually with a software development or business angle. [for example, his series of posts on Source Control HowTo, especially the section on Branching and Merging].

He covers issues such as hiring staff, finances and marketing in a style aimed at programmers, interspersed with anecdotes and humor.

Eric is honest and right on the mark when he says “Don’t take anybody’s guidelines too seriously”, as what works for one person in one situation might not apply in another.
Chapter 4 “Finance for Geeks” was particularly interesting and contains basic accounting information you should be aware of if you are setting up a business venture.

It is often said that successful business people are those that learn from their mistakes, and in chapter 7, “Make More Mistakes”, Eric describes several examples where he has made a few ‘whoppers’ and learned from them the hard way! Admitting your own mistakes is not always easy, learning from them and moving on to something else is one of the traits that distinguish successful businesses from those that fail.

I particularly liked Eric’s ‘conversational’ writing style and his ability to weave ideas familiar to ‘geeks’ into the text, such as his NetHack analogy of the “Gauntlets of Fumbling”. If you have never played NetHack, I won’t try to explain…just Google it! Definitely worth reading.

MIT Open Courseware: Advancing Education for Free

I recently posted a short list of links to mathematics resources that I’d come across. I was speaking to a colleague and he mentioned the MIT OpenCourseWare initiative, which I had not heard of:

“OCW shares free lecture notes, exams, and other resources from more than
1700 courses spanning MIT’s entire curriculum”


This collection of lecture notes and examples is nothing short of amazing. It covers a whole range of university level courses, including mathematics.

Thanks to Leigh Mitsopoulos for making me aware of this resource.

Perth .NET User Group Meeting, October 4th: Visual Studio 2008

Join us at the Perth .NET Users Group October 4th to hear Nick Randolph present on the upcoming version of Visual Studio 2008. In this session, Nick will cover some of the language changes, including Linq, extension methods, anonymous types and xml integration, as well as some of the rapid application development features. Nick is a Microsoft MVP, and currently the lead developer for Intilecta Corporation, an ISV innovating in the area of behavioral intelligence and data visualisation. More details here: Visual Studio 2008: Languages, Features and Frameworks with Nick Randolph

TOPIC: Visual Studio 2008 with Nick Randolph
DATE: 4th October, 5:30pm
VENUE: Excom, Level 2, 23 Barrack Street, Perth
COST: Free. All Welcome.

There will be a couple of (as yet unspecified) give aways! If you want to get a seat, try to arrive early. Also, don’t forget we have a weekly informal coffee meeting at “Tiger Tiger”, Tuesdays at 1:30pm in the city.

Mathematics Books/Material Online (much of it free!)

Here are a few mathematics resources that I have found useful.

Introduction to Complex Analysis: WWL Chen
http://www.maths.mq.edu.au/~wchen/lnicafolder/lnica.html
This is very clearly written and better than most books I have read. The explanations and examples really stand out.

Complex analysis and Functional Analysis: Douglas N. Arnold.
http://www.ima.umn.edu/~arnold/502.s97/complex.pdf
http://www.ima.umn.edu/~arnold/502.s97/functional.pdf
2 excellent documents. The first is probably a little more accessible than the second which requires a substantial mathematics background.

A First Course in Complex Analysis: Beck, Marchesi and Pixton
http://math.sfsu.edu/beck/papers/complex.pdf

First Course in Linear Algebra
http://linear.ups.edu/download.html

Cauchy-Schwarz Master Class: by J. Michael Steele
Whilst this book is not free, several sample chapters are downloadable (http://www-stat.wharton.upenn.edu/~steele/Publications/Books/CSMC/CSMC_index.html ). A truly remarkable book whose clarity and insight is a rarity amongst such books, which often gloss over details and leave the reader baffled. Although a specialised work, I have come across very few mathematics books that can equal it as an educational tool. If you are about to embark on a postgraduate Mathematics (or indeed undergraduate) course of study make sure you read this book.

List of Free Mathematics Books: a great resource!
http://www.math.gatech.edu/~cain/textbooks/onlinebooks.html
This should be your first port of call if you are looking for free online material.

Introduction to Tensor Calculus and Continuum Mechanics
http://www.math.odu.edu/~jhh/bookpdf.zip
by John H. Heinbockel

Concrete Mathemathics, 2nd Edition. (aimed at CS postgraduate students)
http://www.amazon.com/Concrete-Mathematics-Foundation-Computer-Science/dp/0201558025
Not a free book, but if you are about to pursue Computer Science postgraduate studies in algorithmics, complexity analysis or a related subject, then this work is required reading.

If you know of any other high quality work, free or otherwise, please let me know.

New Version of NDepend

Patrick Smacchia at NDepend let me know that new trial and PRO versions of NDepend (2.4) , the code metric and dependency tool, are now available. They have been working hard on simplying the interface and making it more intuitive. One of the things I love about NDepend is that it has its own TSQL-like query language built in! There are a few new tutorials posted as well.
