Telltale Signs Of A Failed Software Project

Like everyone else who’s worked on a slew of team-based software development projects, uber C++ blogger Danny Kalev has his own thoughts on why projects fail. In “Telltale Signs of a Failed Software Project, Part I, Danny ominously describes “The Emperor’s New Clothes Syndrome” as follows:

The first ominous sign is the emperor’s new clothes syndrome — as a new recruit, you try to study the project. You’re reading the specifications, perusing those lovely Data Flow Diagrams (DFDs) or UML charts and you still can’t get the hang of it. “What on earth were they thinking? It simply doesn’t add up!” you’re muttering silently. At some point you realize that it’s not you — it’s the project itself. What you’ve been reading is simply a collection of smoke and mirror effects meant to appease the high management. Little by little you get the picture: your colleagues know that it’s not working but they won’t admit it in public. If you dare exposing the truth you’ll be denounced as an ignorant, misfit traitor. You have two choices: quit silently, or join the rest, pretending all is well.

Hmm, I think Mr. Kalev may have missed the point that his second-to-last sentence; “exposing the truth and being denounced as an ignorant, misfit traitor“, is also a choice – albeit one that is auto-discarded by all sane persons. Ya see, if you’re not perceived to be a cross-eyed Columbo, a court-jester, or an innocent (but naive) child when you state your concern, you’re sure to get hosed down by the powers that be.

 

Have you ever tried to call-it-like-ya-see-it in front of the papal infallibles? If so, which halloween costume did you don? Columbo, Court-Jester, Innocent Child, or “other“? Surely, you’ve done it at least once, right? If not, why not? If so, then what kinda blowback did you receive – and did it force you into “quiet desperation” mode? Come onnnnnnnnn, don’t be shy – share your story with BD00 and the two other regular readers of this blog.

Moving, Initializing, And Hotdogging

February 8, 2011 1 comment

In an interview with C++ creator Bjarne Stroustrup, Danny Kalev asked Bjarne several questions about the major features being incorporated into the venerable C++ language via the C++0x standardization effort. Here’s one such Q+A exchange:

I know, I know. The “*” should be a “+” in the free function declaration box above. But does the typo really detract from the message being conveyed?

So, how hard is it to write a move constructor implementation? It’s as hard as this:

Notice how the lower level reference-to-a-reference (i.e. rvalue reference)  feature in the Matrix move constructor enables the higher level “move” feature to be easily written. This capability to move big stuff around instead of copying the behemoth will be a great addition to the language, especially to library writers, no?

Bjarne’s examples of the new “uniform and universal initialization” C++0x feature jacked me up too:

We can use the {…} notation for every initialization and wherever we initialize an X with {v} we get the same resulting value. That’s a major improvement over C++98’s non-uniform set of alternatives using the =v, ={v}, and (v) notations:

With any new and powerful tool, there’s always the danger of “hotdoggers” conniving to show how much smarter than you they are. Here’s a typically wise and insightful, and universal quote from Bjarne on the topic:

Before we get to benefit from the simplifications offered by C++0x, we may go through a period where too many people try to show off their cleverness by enumerating language rules and digging into the most obscure corners. That can do harm.

You’re not one of “those” people are you? I’m not. Luckily, I ain’t smart enough to be a hotdogger. But if I was brilliant…….

Note: I know that the code above is really C, but it was the first googled C++ example I stumbled across.

C++ Dudes To Follow

If you’re a twit like me, and you also “do” C++, you might want to follow these people and resources on twitter:

They don’t tweet much, but when they do, they’re worth listening to. Do you know of any other C++ twitter resources that I should add to my list?
