Roy Osherove book on "The art of unit testing"

Just found out from Roy Osherove's blog that his book on "The Art of Unit Testing" is available for purchasing online -- well, the first 5 chapters are, but then you get the next as they're being published. Roy uses NUnit to illustrate unit testing concepts and techniques, but that shouldn't deter you from buying the book, because the principles are pretty much the same in all languages. I'm a long time reader of Roy's blog and I can say this is good stuff, judging by his past posts on unit testing and mock testing techniques.

Beware of timings in your tests

Finally I get to write a post about testing. Here's the scenario I had to troubleshoot yesterday: a client of ours has a Web app that uses a java applet for FTP transfers to a back-end server. The java applet presents a nice GUI to end-users, allowing them to drag and drop files from their local workstation to the server.

The problem was that some file transfers were failing in a mysterious way. We obviously looked at the network connectivity between the user reporting the problem initially and our data center, then we looked at the size of the files he was trying to transfer (he thought files over 10 MB were the culprit). We also looked at the number of files transferred, both multiple files in one operation and single files in consecutive operations. We tried transferring files using both a normal FTP client, and the java applet. Everything seemed to point in the direction of 'works for me' -- a stance well-known to testers around the world. All of a sudden, around an hou…

Barack Obama is now a connection

That's the message I see on my LinkedIn home page. How could this be possible, you ask? Well, yesterday I checked out my home page, and I noticed the 'featured question of the day' asked by Barack Obama himself (of course, the question was "how can the next president better help small businesses and entrepreneurs thrive".) A co-worker decided to send a LinkedIn invite to Barack. A little while later, he got the acceptance in his inbox. I followed his example, just for fun, and what do you know, I got back the acceptance in a matter of SECONDS, not even minutes! It seems that B.O. has set his LinkedIn account to accept each and every invite he gets. I guess when you're running for president, every little statistic counts. He already has 500+ connections, and I'm sure the time will come when he'll brag to the other candidates that his LinkedIn account is bigger than theirs.

The bottom line is that YOU TOO can have Barack as your connection, if only to br…

I must be bored out of my mind

...otherwise why would I have taken the time to get my nerd score?

Now YOU do it!

Security testing book review on Dr. Dobbs site

I wrote a review for "The Art of Security Testing" a while ago for Dr. Dobbs. I found out only now that it's online at the Dr. Dobbs's Portal site. Read it here.

Weinberg on Agile

A short but sweet PM Boulevard interview with Jerry Weinberg on Agile management/methods. Of course, he says we need to drop the A and actually drop 'agile' altogether at some point, and just talk about "normal, sensible, professional methods of developing software." Count me in.

Jakob Nielsen on fancy formatting and fancy words

Just received the latest Alertbox newsletter from Jakob Nielsen. The topic is "Fancy Formatting, Fancy Words = Ignored". I'd have put 2 equal signs in there, but anyway....The 'ignored' in question is your web site, if you're trying to draw attention to important facts/figures by using red bold letters and pompous language. Nielsen's case study in the article is the U.S. Census Bureau's homepage, which displayed the current population of the US in big red bold letters, and called it "Population clock". As a result, users were confused as to the meaning of that number, and what's more, they didn't bother to even read the full number, because they thought it's an ad of some sort. Interesting stuff.
