Life of a Network Packet

Introduction

You type “translate lorem ipsum” into Google’s search bar and press Enter. Roughly 200 milliseconds later, ten blue links and a translation widget appear on your screen. In that fifth of a second, your keystrokes triggered a cascade of protocols, each handing off to the next like relay runners passing a baton across the planet. A name was resolved, a connection negotiated, encryption established, a request dispatched, routed through a dozen machines, answered, and rendered — all before you could blink twice.

Open Banking in Australia

I’d just like to scribble out my outrage on this topic.

In Australia, there is a new(ish) Open Banking Project which via the CDR (Consumer Data Right), is intended to empower customers.

Instead, what has happened is that the little guy is once again being fucked.

The approved Third Party Vendors must be ACCC compliant which costs lots of money. This cost is then paid by giants such as Basiq, Adatree, Skript.

Ultimate Frisbee Cutting Patterns

Mambo’s upline cut

  • plant hard with right-foot
  • footwork around into inside lane
  • sprint straight.

AJ’s 7 cut

  • swing disc to centre
  • make (fake) hard clearing cut for the disc back onto the open side
  • when throwing lane is optimal, run around defender, and run the length of the 7 shape to be thrown an inside flick break.

Serenity Prayer

Reinhold Niebuhr

God grant me the serenity
to accept the things I cannot change;
courage to change the things I can;
and wisdom to know the difference.

Bus Stop Poems

Mare

Giovanni Pascoli 1855-1912

M’affaccio alla finestra, e vedo il mare:
vanno le stelle, tremolano l’onde.
Vedo stelle passare, onde passare:
un guizzo chiama, un palpito risponde.

Ecco sospira l’acqua, alita il vento:
sul mare è apparso un bel ponte d’argento.

Ponte gettato sui laghi sereni,
per chi dunque sei fatto e dove meni?


I look out the window, and I see the sea:
the stars drift by, the waves shimmer.
I see stars passing, waves passing:
a flicker calls, a throb replies.

Now the water sighs, the wind exhales:
on the sea a silver bridge appears.

Bridge thrown over silent lakes,
for whom are you made, and where do you lead?
