No One Likes GUIs - Does a GUI or command line interface make more sense for developers?
Tool Costs - Do firmware development tools cost too much?
Clairvoyance - Without clear requirements it's tough to build decent software. Many would argue it's impossible. Yet too many of us wind up guessing what the code is supposed to do.

Professionals - Why can't we get no respect? Does anyone think engineers are professionals?

On Getting Respect, Redux - Maybe we don't want any respect after all. This leads to a prediction about the nature of engineering jobs in the future.
Topsy Turvey - Firmware is topsy-turvey. Unlike most engineering, adding margin costs big development bucks.
Just Reset It - Everything crashes all the time. Or so it sometimes seems. I'm sick of cycling power, removing batteries and the like. Are there any options?
I'm OK, You're OK - Perception is more important, it seems, than reality, whether it's choosing insurance or paying an engineer's salary.
Killing Time - Real-life, daydreaming, Slashdot and telling anecdotes consumes a big chunk of the work-week. Is this normal?
A Feel For Things - EEs have a feel for circuits, Justin Timberlake a feel for, uh, whatever, but do firmware people develop a feel for code?
No Cute Code - C is a very expressive language. We can make working code that's ugly, pretty, silly or just cute. That's not always a good idea, though.
A Value Proposition - Methodologies are great but vendors do a lousy job of proving their approaches are any good. So practically no one buys the tools.
The Commoditization of Software Development - Software development went from an artistic process, to a sort of science, back to the arts, and is now just a commodity.

Teaching Testing - Testing? We don't need no steenkin' testing, at least at the college level.
Abused by the Machine - The machine sucked in Jack's ATM card but hung. Where's the cash?
Gaining Creativity - Is it "a RTOS" or "an RTOS"? Does the curly brace go on a line by itself, or as part of the next statement?
Geeks On Call - Vision-challenged? A lot of us are. Why, though, are glasses the thickness of coke bottles an enduring image of geek-dom?
Some Assemly Required - In a world of high level languages, does being an expert assembly language developer help one craft better C/C++ code?
The BUG Tax - A tax is an expense levied on citizens, often without the payer's approval. Are bugs a form of taxation? And how much is the bug tax, anyway?
The Two Things - It's enlightening - or at least a lot of fun - to try and express the essence of a profession with just two facts. What are the two facts for embedded systems?
Separating Functions - Architects design, contractors build. Software engineers design, estimate, code, debug, test and document. Maybe the Jack-of-all-trades model is flawed?
Cheap Changes - Agile methods appealingly promise a drastic drop in the cost of making code changes. Utter nonsense.
A Shifting Landscape - Microsoft's new CE license targets the GPL, while Wind River now embraces Linux and offers alternatives to per-unit royalties. Everything we know about OS licenses is changing.
Using Slow Downloads - Get buff! Write buggy code.
Static Analysis Tools - We have a wealth of tools that help us generate better software, tools that delve deep into the code and highlight potential errors before debugging starts. Surely you use these. If not, why not?
Real-Time Firmware Updates for the Dishwasher - Lots of embedded systems use desktop OSes and processors. What distinguishes an embedded app from a PC? Could the fundamental difference be quality?
Specialization - The evolutionary impetus to specialize or die is changing the nature of embedded development. It's hard to be a generalist when systems explode in complexity and size.
Radio Days - Efforts to clean up our rivers and air aren't enough. We need to preserve the pristine wilderness of the RF spectrum as well.
Who's at Fault when code Kills? - In 2001 a software error in a radiotherapy device killed a number of cancer patients. Just this week a Panamanian court sentenced the guilty. Did those responsible for the bad code go to jail?
Software Aging - Software rots. It generally ages badly, especially when maintenance people hack in quick fixes instead of cleanly excising the necrotic tissue and healing the wound.
Bonus Time - How will programmers' bonuses stack up this year?
Device Software Optimization - Marketing-speak is now taking over the embedded industry. What are these folks talking about, anyway?
Analogies - We have rotten tools. At best they give us only a crude analogy about our code. The future holds more visceral visualizations.
Productivity - How productive are you? Do you track the numbers? Why not?
iPods for the Masses - Offices are so noisy it's hard to be productive. To compensate wise managers should provide MP3 players to the developers.
Writing Rite - Emale iz fast but giffs a image of who u r. Rite pour Englsh and ur reader wll think u is an idiot.
Old and In The Way - Few engineers stay in the field past age 50. Are these people really dinosaurs? Is their experience a useful resource we're squandering?
Generational Differences - Some products are too hard to use. Others have secret modes nearly impossible to access. But most of it baffles an awful lot of people.
Anyone Can Do It - Don't know embedded systems? No problem! Take a week-long programming class and then start cranking code.
See Ya Carly - Carly Fiorina is out. There's talk of selling off the printer division. Turmoil, for a time, is sure to follow.
Button Pushers - Who can resist pressing a button on a cool-looking panel covered with switches and blinking lights? What happens when we play with the buttons and crash the code?
Mr. Fixit - Consumers are baffled by their technology, and have largely given up trying to understand anything more than which button to press. Isn't it important to understand and master the technology?
It's Show Time - If you're going to San Francisco, be sure to wear some flowers in your hair. And check out the ESC.
Medical Upgrades - A systems engineering manager writes that the tsunami of embedded systems coming into his hospital have created new integration and support issues largely unaddressed by the vendors.
Software is Cheap - Though traditional wisdom claims software is hideously expensive, in fact it's pretty darn cheap. At least compared to the alternatives.
Software Engineering is NOT an Oxymoron - Is software engineering an engineering discipline, a science. or one of the liberal arts?
Brave New World - In the Brave New World of product development, lawyers may become more important than engineers.
Advanced Degrees - More engineers seem interested in getting their MS degree. Jack wonders why, since there seems so little benefit to one's career.
40 Hours - Though overtimes seems inevitable in this industry, companies have a responsibility to manage it properly. and fairly compensate the developers.
Failure is an Option - Zero percent of big software projects succeed. Even smaller systems are generally delivered late and with only a subset of the promised functionality.
Sea Code - Want to go on a cruise. and get paid? You, too, can make $1800/month while living the life of luxury, anchored 3.1 miles off LA for months on end.
Spares & Tools - What's with us engineers? We collect spare parts and tools more assiduously than most folks buy lottery tickets.
Human Failure - A Cessna approaches Washington DC. Air traffic control goes into overdrive. Was the pilot evil or just confused?
Certifications - As firmware controls ever-more of our lives, and is responsible for legions of safety critical applications, will developers someday require certifications?
Wall Warts - Want to make a million bucks? Here's an idea that could launch a couple of startups.
The Hundred Years War - Feedback stabilizes systems. but only if it's used. We developers need to reflect on our practices from time to time.
Professionals - If we want to be treated as professionals, we must act as such. That starts with continuous education.
Liability - EULAs are merely tools to thwart lawsuits, yet the cruddy code they guard can reap havoc on our computers.
At Sea - There's no escaping the world of embedded systems - even if we wanted to.
Who Needs a Degree? - How important is a degree, anyway?
Code Guardians - Who is really responsible for the code? Should we assign a strong guardian angel, someone with the authority to say "no!", to insure we're not taking shortcuts?
The New Greenies - The environmental movement has neglected their best ally. Us.
Balance Sheets - A balance sheet tracks the value of all of a company's assets. except the most expensive. Like software and IP.
One Hour - What a long, strange trip it's been. One generation ago computers were guarded by a tribe of high priest operators. Now we buy them like appliances.
