I don't have much, but I am willing to give up any and all of my Christmas
presents if you can see your way to bring Christmas to a boy in the UK. You
see, they have even less there in the UK - surveillance cameras everywhere to
make sure they keep in line and boiled gruel twice a day if they are lucky.
There is a boy, Michael, he works ever so hard - first shift at a coal mine
and then second shift at a textile mill - and then after 2 10 hour shifts of
backbreaking labor, he only has a couple hours per day by candle light while
eating his nightly gruel to work on Xen for Fedora.
Mr. Scrooge and the other fat cats at Scrooge, Inc. tell Michael and the rest
of us that we should be happy with their KVM. This, while dining on the finest
roasted meats and full cream puddings in front of roaring fires fueled by wood
gathered by orphans and widows paid in crust of week-old bread while young,
robust, well-fed hamsters on whale oiled wheels run their giant gleaming
servers - you see Santa, our hamsters are gaunt, long-of-tooth and have only a
portion of Michael's nightly gruel that he is able to share with them and alas
we have no monies for whale blubber with which to oil their wheels.
The rich seem to believe that we press for Xen only through laziness or
recalcitrance - I can assure you this is not the case, we have simple needs
and wants, we ask not for full bodied HVM capable X5680s but only that our
humble, yet proud and hardworking Core, Pentium and Opterons are not dumped on
the ground and doused in kerosene that they might never be used again. We are
not asking for luxury and riches, just humble tools that a man might fashion
an honest day's work from what he has. These hopes ride on young Michael's
work. They are not the sole hopes of Michael or me but the hopes of thousands,
living lives of quiet desperation, hoping beyond hope that one call goes their
way, of having one branch to grab onto.
Dearest Santa - please don't leave these desperate souls a lump of KVM in
Thank you and god bless us every one!
