Tightly integrated? Just say no!
As I write this, there is a barely audible, irregular thumping noise
emanating from a dusty 386 PC in the corner of the room. I fear a system
failure is on the way.
The noise reminds me of a recent echo cardiograph I undertook in which
the full extent of my advanced addiction to caffeine was transformed
into sound. Thumping sounds caused by palpitations emanating from the
most important muscle I possess. I no longer drink coffee by the way.
If the noises from the PC in the corner get any louder, I can think of a
number of people who work with me who may find themselves experiencing
stress - rather then caffeine induced - palpitations. You see, that
dusty PC in the corner is running a system last touched about seven
years ago. I kid you not. Seven years ago. It has given tireless, 24/7
service during those years with only occasional weeding, mulching and
the odd tender loving warm boot from tender, loving hands.
Sure we have backups. Weekly backups. We even have a machine in hot
backup mode ready to take its place if it goes belly up. Despite all
this, we are still nervous. Nervous because the system has not been
touched in years. Nervous that a number of its hardware and software
components are now antiques in IT terms. Nervous that while some of the
system was built in-house, some of it was outsourced and the people
responsible for its development have long since disappeared to find
themselves in the jungles of South America or snowboarding their way
around the USA.
We are nervous because we know in our hearts and souls, that under that
irregular thumping noise, lies a ball of tightly integrated software
applications.
For 'tightly integrated' in the above sentence, feel free to read 'ball of mud'. Unless you are extremely lucky, you have some balls of mud in your sphere of influence too. Can you think of any systems you know that you are afraid to touch? Systems that have become so tightly
knotted over the years that no one human brain understands it all both
at a conceptual and detail level? I thought so.

Where Google Chrome security fails: the password
I heard mention that the Chrome OS will have some sort of encryption available a la bitlocker. If it's possible to encrypt personal data using another password or key, then it may have potential for very secure data.... And Ubuntu has an 'encrypt home directory' option, perhaps google should follow suit.
