Software Development: Opinions

Heathrow’s T5 software testing issues have highlighted the importance of software testing, I hope that lessons have been learnt and that CIO’s across the world will take note in the future.

As my colleague Martin Heller recently observed, smart coders always optimize the slowest thing. Trying to optimize every trivial performance issue in your code is just chasing your own tail. You should find the one problem that's causing the biggest performance hit and fix that first.

The best technology products are often the product of a singular vision. Look at Apple. Look at Nintendo. These companies' enduring successes owe their existence to the presence of a strong guiding hand: someone whose exacting standards ensure that the project never strays too far from its core goals and principles.

I haven't viewed an Intel Developer Forum with anticipation for some years. I am looking forward to this one, because unless there is some surprise afoot, this is where the Nehalem architecture should make its silicon debut. Intel tipped this by announcing the name of its first incarnation of Nehalem, a desktop chip dubbed "Core i7." Desktop CPUs tend to leave out features touted in literature describing the most potent implementation of a new architecture, so I don't expect Core i7 to embody Nehalem as IT will come to know it. I do expect to see Nehalem in production ahead of schedule, and that suits me. Nehalem could mark a return to a strategy that takes competition into account, and which includes entry-level RISC in the scope of competitors.

I love lampooning the FOSS community. These self-righteous cyber-hippies are almost always good for a blog entry or two per month. And because many of them can't resist airing their own community's dirty laundry, I have no shortage of story ideas to choose from.

Could Microsoft be switching away from Windows?

I'm continually amazed at how the premier Web properties are willing to share what they are doing. We get to peek behind the curtain routinely. Google and Yahoo both have good lab pages, but there's some seriously experimental stuff on the Mozilla labs page. Here's what they're up to.

There you are, sipping your latte while banging out code in Django, Drupal, and Ruby, and feeling pretty cutting-edge. Sure, those are the hot skills of the moment, and they'll probably help you land your next job. But take a minute to think about the guys who came before you and the tools, particularly COBOL, they used. And give 'em some respect. They deserve it.

I was all set to give this week's column over to a new register-direct implementation of a JavaScript interpreter that's many times faster than all currently available implementations. It's not exactly growing hair on a billiard ball, but a nitro-boosted JavaScript will put a shine on AJAX and keep my most beloved language on track to becoming the gold standard for dynamic languages.

You may have noticed this has been a slow week in Cringeville. Well now the truth can be told. For the past five days I've been held captive in Amsterdam by a small group of mad Dutchmen. They locked me in the tower of a Swiss hotel, trundled me into a van with three other captives, drove us around the Dutch countryside until we were disoriented, and forced us to consume vast quantities of rich foods delivered in thimble-sized portions accompanied by heroic volumes of tangy Teutonic wine. It was Hell.
