The Big Technical Mistakes of History
An anonymous reader tips a PC Authority review of some of the biggest technical goofs of all time. "As any computer programmer will tell you, some of the most confusing and complex issues can stem from the simplest of errors. This article looking back at history's big technical mistakes includes some interesting trivia, such as NASA's failure to convert measurements to metric, resulting in the Mars Climate Orbiter being torn apart by the Martian atmosphere. Then there is the infamous Intel Pentium floating point fiasco, which cost the company $450m in direct costs, a battering on the world's stock exchanges, and a huge black mark on its reputation. Also on the list is Iridium, the global satellite phone network that promised to make phones work anywhere on the planet, but required 77 satellites to be launched into space."
Rim shot...!
No sig today...
There was no technical flaw in Iridium. It was stated what it would do. It did it. Someone screwed up the business plan, but there was no technical mistake. They knew it took 77 satellites for what they wanted. And they launched them all and they worked flawlessly. Now, if only they had sales to match the business plan, they'd be billionaires. But again, unrelated to any technical issue.

When I saw the title, I immediately imagined the Maginot line. Thousands more examples could come to mind.
Could somebody please explain to the author of the articles that Technology is more than computers/gadjets and older than 10 years? It is an epic history that goes along with mankind.
Seriously, we have got to stop with the hyperbole before our children don't know the difference between a War on Drugs and a War in Iraq.
We we say of all time, I think of things like lead plumbing in Rome, or the suspension bridge that got tore apart by a mere breeze.

Always going forward, 'cause we can't find reverse.
Intel's 8086 CPU, Intel's first 16-bit processor, was possibly much worse than any of those mentioned because it affected all of us. Intel chose to continue the quirkiness of the 8008 rather than abandon it.
... and was therefore fairly awkward (and remained so until the 80386)."
Just before the time of the introduction of the 8086 I knew a chief of technology of a high-tech company who was waiting for the 8086 as though it were a combination of Christmas, his birthday, and the birth of his child. He would start every conversation by telling everyone Intel's release date for the 8086.
The day of its release, he was miserably unhappy. Intel chose to continue an architecture that made assembly language programming and debugging of high-level languages more difficult.
Wikipedia says about the 8086: "Marketed as source compatible, the 8086 was designed so that assembly language for the 8008, 8080, or 8085 could be automatically converted into equivalent (sub-optimal) 8086 source code, with little or no hand-editing. The programming model and instruction set was (loosely) based on the 8080 in order to make this possible. However, the 8086 design was expanded to support full 16-bit processing, instead of the fairly basic 16-bit capabilities of the 8080/8085."
The problem was that the quirkiness has been extended to the 32-bit processors of today. The Wikipedia article says, "The legacy of the 8086 is enduring in the basic instruction set of today's personal computers and servers..."
And, "Programming over 64 KB boundaries involved adjusting segment registers
Everyone on the planet who used or were affected by computers then suffered because the debugging was much more complicated than if Intel had chosen to make the operation of the 8086 simpler.
"Such relatively simple and low-power 8086-compatible processors in CMOS are still used in embedded systems."
I thought the bidding would start at $0.99999574
