The first thing that went through my mind (with some additional work, and all that is needed is illustrations and a publisher..):
A is for Asynchronous, the way our code should be
B is for Beta, the first stage of our code the user will see
C is for Capacity, for this planning helps our hardware not
fail,
planning capacity helps our product meet our users at scale
.
D is for Datagram, which you may not get from me
E is for E-tag, for caching is key
F is for Freedom, the state information wants to achieve,
follow information through history if you want to believe
.
G is for Google, the advertising and indexing whale
H is for Hystrix, because Netflix Tools are for scale
I is for the Internet, for without it, many start-ups would fail
I is also for iPhone who's apparently in jail
.
J is for Javascript, with a new frameworks each week
K is for Kill, because scripts can misbehave and memory can leak
L is for LifeSize, for meetings about meetings must be
M is for Metadata, because tracking in bulk is (mumble, mumble, something, something), look! "privacy!"
.
N is for NoSQL, for relational data is dead
O is for Octocat, who houses our code so it is not in our head
P is for a Penguin named tux
Q is for Quiet, lost to the the tide of the open office flux
.
R is for Rabbit, because some problems require a Queue
S is for Secure, for we have our our user's data to lose
T is for the terminal, for how else can we see ascii Star Wars
U is for UTF-8, who's lack of handling makes bugs in our source
.
V is for Vitesse, never has mysql DBs been so easy to scale
W is for the 5 Whys, that guides us in post-motems when we fail
X is for Executable, which chmod can help our script to be
Y is for YCombinator, for many a start up, encubators are key
.
And Z is for Zsh, not your ordinary shell
These are the letters, remember them well
These are the letters, from A to Z
These are the letters, next time will you please say them with me?
