To my knowledge (although I'm not a NASA watcher with as much fervor as some) I don't believe the SSMEs have EVER BEEN analyzed and re-engineered to create characterizations of their failure points, reliability, etc
This is a very important consideration in any engineering exercise, however, when have the SSME's ever been a cause of failure? To the contrary, don't they have an excellent performance track record?
Let's try to keep our eyes on the ball, to date, the catastrophic failures of the program have been caused by:
quality control in the SRB (the infamous O ring that led to the first explosion)
damaged thermal-tile / aerodynamic surfaces from ice shedding
Throughout the Shuttle program there have been endless other problems that are probably related to the Administrator's comments about the agressive design. NASA tried to build an Orbiter for the 21st century using 1970's technologies. Just for example, by 1998, the average laptop had more computing capability than the entire SST while it embedded HUNDREDS of sensors for data gathering and a fly-by-wire system for manual flight control.
When the shuttle program started it was visionary, but it got bogged down trying to deliver the sun, moon and stars on a government controlled budget. NASA's big mistake was continuing the program after it became obvious that the design flaws would cripple it. The unanswered question is, when did it become obvious?
The article is mentions the rise of anti-spyware and how it usually cleans up suspect cookies.
From my experience with average users, clients, co-workers and family, most users have no clue what the anti-spyware is actually doing, they just follow along blindly. Personally I think this a great improvement over the truely clueless who don't practice safe browsing of any sort.
Good Design (aka Big Design Up Front) is very effective when the problem domain is well understood or there exist a reasonable number of known solutions to choose from. Text editing is a good example of this, people have been writing text editors for over 40 years so there shouldn't be too many surprises and there are lots of examples. (Telephone signal exchange is similar...) For these problems a very formal approach should work well and result in a well documented and well designed system.
Other problems, usually in newer fields of endeavor, lend themselves to more dynamic software creation strategies with less stringent design phases such as hacking, exploratory programming, prototyping and good old XP. It's very hard to write requirements, functional specifications or even UML diagrams for a system that does things nobody has even dreamed about.
In an ideal world both approaches will result in a good design. What started as a hack can turn into a prototype and evolve into a design, the trick is to document it all... but that would require infinite time and infinite resources. This might occur in large open source projects where the user and development communities are large enough to represent statistical universes but in the corporate world where the bottom line drives everything and therefore time and resources are limited shortcuts are taken. Sometimes this results in brilliantly designed but undocumented applications, but just as often the result is a giant ball of mud that will scare the willies out of the first intern or student hired to maintain code.

I'm beginning to think that webauthoring should be licenced so that if you're not knowledgable enough to write W3 compliant xhtml from memory you should have to use a tool that does.
Similarly, Frontpage is a crime against humanity!
All kidding aside, how do we educate the unwashed masses? The grand majority of web users out there don't even know what raw HTML looks like, much less nebulous issues like CSS compliance and xhtml. Why should they even care?
I don't get it! Who's going to buy it?

Who is going to spend time and money on this thing?
It's almost as expensive as XP Home edition and half a dozen different Linux distros can be had for free.
Who's going to pay 99 Euros for a squeaky new OS?
Are there even any applications for it?
Free I could understand, we hobbiests are crazy, but 99 Euros? WTF?
But then again, so are sledgehammers and landmines. Just for kicks see how your girlfriend reacts when you jump into bed with a flack-jacket and a 20 lb. sledge.

Somebody still has to remind me why CD ripping is different from the 70's & 80's when we would pool our funds for someone to buy the album and make lots of tapes...
Under the new solution, tracks ripped and burned from a copy-protected disc are copied to a blank CD in Microsoft's Windows Media Audio format. The DRM embedded on the discs bars the burned CD from being copied.
So this will only affect you if you use Windows Media Player. Darwin in action?
If that 90% problem goes away, and the music industry giants stop complaining, we can return to business as usual!
you have plausible deniability that you are just acting as a buffer and ferrying the data for someone else instead of yourself.
Try explaining that to the Men in Black. The CIA/NSA types will just laugh.
Yes, this is tinfoil hat land in the U.S. but for places like China, Corea, Myanmar, etc. plausible deniability is simply not an option, just being a link in the chain will land you on the short path to the salt mines.
Since nobody else appears willing to speculate, I'm going to guess that they'll pay a severe price in Core 4 with incompatibility and instability, but the lessons they learn will pay off in Core 5... if they survive that long.
But IIRC, upgrading my gcc on Fedora Core 2 made it almost impossible to install the NVidia Kernel mod. But then, NVidia is ALWAYS a special case isn't it.
sigh
Compatibility? Linux testing?

GCC 4.0.0 Released
·
· Score: 4, Interesting
Just about every time I have to rebuild a kernel or build a kernel mod I get my butt kicked by gcc versions. So my questions are?
Are there compatibility issues with existing binaries?
What does this do to existing code?
How will this effect existing distros?
Is any distro planning on supporting 4.X soon? (And is that a good thing or a bad thing?)
Any CGI that is not supported by a module like mod_perl or mod_php has to run as a separate process whether you use IIS or Apache
Have you actually even used Windows as a web server?
I have, and after years of hacking Solaris and Linux I was stunned to discover how bad CGI performance was under Windows, forking (or starting) processes in win32 is significantly more expensive than in any UNIX. For this reason my organization has moved to ISAPI under IIS and apache modules under apache to get reasonable performance on win32.
As an aside, CGI under IIS with an untweaked anti-virus is slower than molasses in January in Val d'Or.
Now windows isn't all bad, it's just a question of what you do with it! My home PC is used 90% of the time for gaming, so what do I run? XP! Why? Because I don't want to spend a weekend messing around with kernel modules to support my video card correctly just so I can discover that my new game only kinda works with WineX.
