But that's a pretty big "if" there
Oh, I agree - you'd have added a lot of hardware complexity and probably more than you'd be able to fit if you wanted to keep 7 of them in the thermal envelope of the Cell.
It depends a lot on the codebase. Codebases tend to accumulate cruft. Having people refactor them because their requirements are different to yours can help, as can having a project developed without key product ship dates as the driving force. The bigger barrier is culture though. It's really hard to have a group of developers that have been working on a project for 10 years in private move to developing in public. In the list, he actually gives different numbers of fail points, more for projects that were proprietary for longer than they were open, which makes a lot more sense than the summary in the 'article'.
The one that I disagree with is 'Your source builds using something that isn't GNU Make [ +10 points of FAIL ]'. I disagree for two reasons. The first is that it implies using GNU make features, which likely means that you're conflating building and build configuration (which should gain some fail points). The projects that I most enjoy hacking on use CMake and Ninja for building by default (CMake can also emit POSIX Makefiles that GNU Make can use, but I take his point to mean that gmake is the only command you need to build, so the CMake dependency would be a problem). LLVM still more or less maintains two build systems, though the autoconf + gmake one is slowly being removed in favour of the CMake one. If I make a small change, it takes Ninja less time to rebuild it than it takes gmake to work out that it has nothing to do if I don't make any changes.
I'd also disagree with 'Your code doesn't have a changelog' - this is a GNU requirement, but one that dates back to before CVS was widely deployed. The revision control logs now fill the same requirement, though you should have something documenting large user-visible changes.
As for "web page", AJAX apps do exactly this
AJAX provides a mechanism for delivering the XML. How many popular web apps can you name that completely separate the back end and the front end and provide documentation for users to talk directly to the back end and substitute their own UI or amalgamate the data with that from other services? Of those, how many provide the data in a self-documenting form?
As I was saying: If your kids are immunocompromised, they have a lot more to worry about than measles. That is, there are many other diseases they have to worry about besides the few we can vaccinate against.
Why do you keep talking about immunocompromised people? The measles vaccine, for example, only works in about 95% of cases, the other people are not immunised. They have no other autoimmune issues and, unless exposed to the measles virus, will have no issues.
Almost everybody in "the entire population" who is vaccinated is protected by the vaccine and hence not "vulnerable". So "the entire population" doesn't become more vulnerable.
If immunity drops below about 93% for measles, then the population no longer benefits from herd immunity. This means that anyone who is not immune (including those 5% who were vaccinated but didn't receive the benefit) is at a much higher risk of being infected. It also means more infections, which increases the probability of the disease mutating, which affects everyone. People who are infected then have compromised immune systems and so are likely to suffer from other infections, which can then spread to the rest of the population.
