   RE: [xml-dev] Re: Can A Web Site Be Reliably Defended Against DoS Attac

[ Lists Home | Date Index | Thread Index ]

The Redstone was an upgraded V2.  The Saturn I was 
was a set of Redstones clustered together (aka, "cluster's 
last stand"). The Saturn V was new system from 
the ground up.  It passed a full-up test on 
it's first launch. Pogoing (tank slosh) was a 
problem but was overcome.  Yes, the liquid 
rocket technology was mature, but the real 
contributor was that the design team managers 
had been working together for many years, some 
as far back as the Rocketry Club in Germany, 
pre-WWII, they understood their risks, and their 
engineering and management techniques were 
applied accordingly.

"We are not in the business of making shoes." 
Werhner von Braun after the Apollo I fire.

"Help! I am trapped in an Arthur Rudolph 
meeting!"  from a note found on the ground 
outside Bldg 4200 during another all night 
design review for the Saturn V.

The ground fire and the Apollo 13 were both 
capsule failures, not launch failures.  
The Apollo 1 fire was a 
result of haste and 'mission fever'.  The 
Apollo 13 was a quality control problem 
(they dropped the tank two years prior 
to launch and there was a wiring short). 
The first case is a bit more like what we 
witnessed in web fielding.  The second case 
is like what we are seeing with the failure 
of webmasters with respect to upgrades and 
server maintenance.

I understand the nature of the beast. My 
job is to make sure my customer does too 
in the face of people who claim 'worse 
is better' and 80/20 is 'good enough'. 
It can be for some applications (say 
a ballistic missile) but for a manned 
flight, no way.  Cheap won't cut it.

The Saturn V built on the redstone and mercury programs, both of which had
"issues", particularly redstone. By the time the Saturn V was launched, the
technology was, uh,  "stable".

Maybe the next rev of the web will be as reliable as the Saturn - although
that hasn't a completely stainless rep with one ground fire and one mission
almost a failure - but I'm not holding my breath. The web will never be a
complete project - it's still evolving, with IP6 on it's way - and it will
never be flawless. I think that's the nature of the beast.
