existing firewall rules
are ineffective to prevent
distributed denial-of-service attack
flooding the heart –
disconnecting communication channel
with the brain
the heart left open,
love virus gets to work
spreading new sensations
which take deep roots,
taking over controls
in a matter of minutes
by the time
incident report is lodged
and root cause analysis
the heart’s assets
have been sieged, and the brain
In computing, a firewall is a network security system that monitors and controls the incoming and ongoing network traffic based on pre-detemined access security rules.
Distributed denial-of-service attack is an attempt to make a machine unavailable to its intended users, e.g. by “flooding” the bandwidth or resources of a targeted system, eventually causing the system to crash.
Poem by Anna at https://whatthewomanwrote.wordpress.com/2016/01/28/broken-controls/
Each evening, shortly after sunset,
darkness covers the land.
Having mystified thinkers for millennia,
the mechanism for this occurrence
has now been identified: migration.
Darkness, it has been found, is composed
of an almost infinite number of particles,
which roost and reproduce up north
where they have fewer natural enemies:
Forest fires, lampposts, lasers, blazing sunlight,
torches, candles, lighthouses, limelight, and electricity
are relatively rare in the polar regions.

For the first twenty years since yesterday
I scarce believed thou couldst be gone away;
For forty more I fed on favors past,
And forty on hopes that thou wouldst they might last.
Tears drowned one hundred, and sighs blew out two,
A thousand, I did neither think nor do,
Or not divide, all being one thought of you,
Or in a thousand more forgot that too.
Yet call not this long life, but think that I
Am, by being dead, immortal. Can ghosts die?
John Donne is one of the great poets. Who can resist sharing one of his poems?
In science and mathematics, accuracy is key. In this poem, Mirslav Holub (an immunologist) reflects on accuracy. This poem was translated form the Czech by Ewald Osers.
Brief Reflection on Accuracy
always accurately know where to move and when,
birds have an accurate built-in time sense
lacking such instincts resorts to scientific
research. Its nature is illustrated by the following
A certain soldier
had to fire a cannon at six o’clock sharp every evening.
Being a soldier he did so. When his accuracy was
investigated he explained:
I go by
the absolutely accurate chronometer in the window
of the clockmaker down in the city. Every day at seventeen
forty-five I set my watch by it and
climb the hill where my cannon stands ready.
At seventeen fifty-nine precisely I step up to the cannon
and at eighteen hours sharp I fire.
And it was clear
that this method of firing was absolutely accurate.
All that was left was to check that chronometer. So
the clockmaker down in the city was questioned about
his instrument’s accuracy.
Oh, said the clockmaker,
this is one of the most accurate instruments ever. Just imagine,
for many years now a cannon has been fired at six o’clock sharp.
And every day I look at this chronometer
and always it shows exactly six.
Chronometers tick and cannon boom.
J J Thompson discovered the electron, and won the Physics Nobel Prize. He also wrote good verse!
In the dusty lab’ratory,
’Mid the coils and wax and twine,
There the atoms in their glory,
Ionize and recombine.
Chorus: Oh my darlings! Oh my darlings!
Oh my darling ions mine!
You are lost and gone forever
When just once you recombine!
In a tube quite electrodeless,
They discharge around a line,
And the glow they leave behind them
Is quite corking for a time.
And with quite a small expansion,
1.8 or 1.9,
You can get a cloud delightful,
Which explains both snow and rain.
In the weird magnetic circuit
See how lovingly they twine,
As each ion describes a spiral
Round its own magnetic line.
From the arc of glowing lime,
Soon discharges a conductor
If it’s charged with minus sign.
Alpha rays from radium bromide
Cause a zinc-blende screen to shine,
Set it glowing, clearly showing
Scintillations all the time.
Radium bromide emanation,
Rutherford did first divine,
Turns to helium, then Sir William
Got the spectrum every line.
Sung to the tune of “Oh my Darling Clementine”
