Development

The Woes of IDEs

An epigram: "We may not feel these limitations until they have been lifted from us, just as we often do not know we are sick until we suddenly feel better. Therefore, it is reasonable to expect that future languages will make us feel those limitations of [our present environments] that are not detectable today." --Gerald Weinberg

Coding Smart: People vs. Tools

Tools can help developers be more productive, but they're no replacement for thinking.

No Source Code? No Problem!

What if you have to port a program, but all you have is a binary?

Another Day, Another Bug

We asked our readers which tools they use to squash bugs. Here's what they said.

User Interface Designers, Slaves of Fashion

The status quo prevails in interface design, and the flawed concept of cut-and-paste is a perfect example.

Stand and Deliver:
Why I Hate Stand-Up Meetings

Stand-up meetings are an important component of the 'whole team', which is one of the fundamental practices of extreme programming (XP).

Microsoft's Compact Framework Targets Smart Devices

Welcome to my first installment of ACM Queue's ToolKit column. Each issue I'll dig beneath the market-friendly, feature-rich exterior of some of the best-known (and some of the least-known) development tools in an attempt to separate the core app from the product spec sheet.

The Big Bang Theory of IDEs

Remember the halcyon days when development required only a text editor, a compiler, and some sort of debugger (in cases where the odd printf() or two alone didn't serve)? During the early days of computing, these were independent tools used iteratively in development's golden circle. Somewhere along the way we realized that a closer integration of these tools could expedite the development process. Thus was born the integrated development environment (IDE), a framework and user environment for software development that's actually a toolkit of instruments essential to software creation. At first, IDEs simply connected the big three (editor, compiler, and debugger), but nowadays most go well beyond those minimum requirements.

Reading, Writing, and Code

Forty years ago, when computer programming was an individual experience, the need for easily readable code wasn't on any priority list. Today, however, programming usually is a team-based activity, and writing code that others can easily decipher has become a necessity. Creating and developing readable code is not as easy as it sounds.

The Demise of the Waterfall Model Is Imminent

Rumors of the demise of the Waterfall Life-cycle Model are greatly exaggerated. We discovered this and other disappointing indicators about current software engineering practices in a recent survey of almost 200 software professionals. These discoveries raise questions about perception versus reality with respect to the nature of software engineers, software engineering practice, and the industry.

Death by UML Fever

A potentially deadly illness, clinically referred to as UML (Unified Modeling Language) fever, is plaguing many software-engineering efforts today. This fever has many different strains that vary in levels of lethality and contagion. A number of these strains are symptomatically related, however. Rigorous laboratory analysis has revealed that each is unique in origin and makeup. A particularly insidious characteristic of UML fever, common to most of its assorted strains, is the difficulty individuals and organizations have in self-diagnosing the affliction. A consequence is that many cases of the fever go untreated and often evolve into more complex and lethal strains.

Intel's Heavy-Duty Dev Tools

In the PC and server worlds, the engineering battle for computer performance has often focused on the hardware advances Intel brings to its microprocessors.

Kode Vicious Strikes Again

Dear Kode Vicious, I have this problem. I can never seem to find bits of code I know I wrote. This isn't so much work code--that's on our source server--but you know, those bits of test code I wrote last month, I can never find them. How do you deal with this?

Kode Vicious: The Return

Dear KV, Whenever my team reviews my code, they always complain that I don't check for return values from system calls. I can see having to check a regular function call, because I don't trust my co-workers, but system calls are written by people who know what they're doing--and, besides, if a system call fails, there isn't much I can do to recover. Why bother?

Kode Vicious Unleashed

Dear KV, My officemate writes methods that are 1,000 lines long and claims they are easier to understand than if they were broken down into a smaller set of methods. How can we convince him his code is a maintenance nightmare?

Kode Vicious Reloaded

The program should be a small project, but every time I start specifying the objects and methods it seems to grow to a huge size, both in the number of lines and the size of the final program.

Comments are More Important than Code

The thorough use of internal documentation is one of the most-overlooked ways of improving software quality and speeding implementation.

Kode Vicious Battles On

Dear KV, I'm maintaining some C code at work that is driving me right out of my mind. It seems I cannot go more than three lines in any file without coming across a chunk of code that is conditionally compiled.

Kode Vicious vs. Mothra

Dear KV, My co-workers keep doing really bad things in the code, such as writing C++ code with macros that have gotos that jump out of them, and using assert in lower-level functions as an error-handling facility. I keep trying to get them to stop doing these things, but the standard response I get is, "Yeah, it's not pretty, but it works." How can I get them to start asking, "Is there a better way to do this?" They listen to my arguments but don't seem convinced. In some cases they even insist they are following good practices.

Mal Managerium:
A Field Guide

Please allow me the pleasure of leading you on an 'office safari', so to speak. On today's journey we'll travel the corridors of computerdom in search of the widespread but elusive mal managerium, or bad manager, in common parlance. They will be difficult to spot because we will be in a sense looking for that most elusive creature of all: ourselves. That is to say, it's quite possible that many of us will share some of the qualities with the various types of bad managers we shall encounter. Qualities that we are loath to admit we possess, I might add.

Kode Vicious Cycles On

Not only does California give you plenty of sun, it also apparently has employers that give you plenty of time to play around with the smaller problems that you like, in a programming language that's irrelevant to the later implementation.

The problem? Computers make it too easy to copy data.

The Heart of Eclipse

A look inside and extensible plug-in architecture ECLIPSE is both an open, extensible development environment for building software and an open, extensible application framework upon which software can be built. Considered the most popular Java IDE, it provides a common UI model for working with tools and promotes rapid development of modular features based on a plug-in component model. The Eclipse Foundation designed the platform to run natively on multiple operating systems, including Macintosh, Windows, and Linux, providing robust integration with each and providing rich clients that support the GUI interactions everyone is familiar with: drag and drop, cut and paste (clipboard), navigation, and customization.

API Design Matters

Why changing APIs might become a criminal offense. After more than 25 years as a software engineer, I still find myself underestimating the time it will take to complete a particular programming task. Sometimes, the resulting schedule slip is caused by my own shortcomings: as I dig into a problem, I simply discover that it is a lot harder than I initially thought, so the problem takes longer to solvesuch is life as a programmer. Just as often I know exactly what I want to achieve and how to achieve it, but it still takes far longer than anticipated. When that happens, it is usually because I am struggling with an API that seems to do its level best to throw rocks in my path and make my life difficult.

Gettin' Your Head Straight

Kode Vicious is hungry. He sustains himself on your questions from the software development trenches (and lots of beer). Without your monthly missives, KV is like a fish out of water, or a scientist without a problem to solve. So please, do you part to keep him sane (or at least free from psychotic episodes), occupied, and useful.

Only Code Has Value?

A recent conversation about development methodologies turned to the relative value of various artifacts produced during the development process, and the person I was talking with said: the code has "always been the only artifact that matters. It's just that we're only now coming to recognize that." My reaction to this, not expressed at that time, was twofold. First, I got quite a sense of déjà-vu since it hearkened back to my time as an undergraduate and memories of many heated discussions about whether code was self-documenting.

Code Spelunking Redux

It has been five years since I first wrote about code spelunking, and though systems continue to grow in size and scope, the tools we use to understand those systems are not growing at the same rate. In fact, I believe we are steadily losing ground. So why should we go over the same ground again? Is this subject important enough to warrant two articles in five years? I believe it is.
