You’ve probably read about Firesheep, the Firefox extension that scans an open WiFi network for unencrypted cookies issued by various popular sites—including Amazon, Facebook, Google and Twitter—and lets you log in as any user it can find.

Until the sites in question fix this long-standing security hole, here’s a few things you can do to help prevent less scrupulous types from ‘sidejacking’ your accounts:

• Use a VPN.
• Use an SSH SOCKS proxy.
• If you use Firefox, install HTTPS Everywhere and/or Force TLS.
• If you use Chrome, install KB SSL Enforcer.

The above are only partial solutions—you could easily broadcast existing cookies before a browser extension kicks in, and VPNs and SSH proxies are only encrypted as far as their endpoints—but they’re better than nothing.

Water drowns your panic like a Sunday blessing.

It’s spring. The sky above you darkens with rain.

You think passion is your only gift, but a sadness 

older than the sea keeps time in your blood. 

Once you saw two skeletons locked in a kiss. 

Time has forgotten them. Time forgets

everything except the swan’s neck reflected 

in the dark fountain and the way it cried out

its silver anthem of loneliness. Do not drink

from here. The water looks cold and clean

but clarity like that only leads to madness. 

Remember when you came here with the one

who held your body even as it changed

beneath his hands and waited for you to

renounce the world? You will never renounce it.

Grigori Yakovlevich Perelman is a Russian Jewish mathematician, who has made landmark contributions to Riemannian geometry and geometric topology. In particular, he proved Thurston’s geometrization conjecture.

In August 2006, Perelman was awarded the Fields Medal for “his contributions to geometry and his revolutionary insights into the analytical and geometric structure of the Ricci flow”. Perelman declined to accept the award or to appear at the congress. On 22 December 2006, the journal Science recognized Perelman’s proof of the Poincaré conjecture as the scientific “Breakthrough of the Year”, the first such recognition in the area of mathematics. He has since ceased working on mathematics. On 18 March 2010, it was announced that he had met the criteria to receive the first Clay Millennium Prize Problems awardof US $1,000,000 for resolution of the Poincaré conjecture but on July 1, 2010 he turned down this one million dollar prize saying that he believes his contribution in proving the Poincare conjecture was no greater than that of U.S. mathematician Richard Hamilton, who first suggested a program for the solution.

Savoring life starts with a mindset. It’s a mindset that believes that excess, that rushing, that busy-ness, that distractedness, isn’t ideal. It’s a mindset that tries instead to:
- simplify
- do & consume less
- slow down
- be mindful & present
- savor things fully

Here’s to the crazy ones.


  The misfits.
    The rebels.
      The troublemakers.
        The round pegs in the square holes.
The ones who see things differently.

They’re not fond of rules.
     And they have no respect for the status quo.

You can praise them, disagree with them, quote them,
     disbelieve them, glorify or vilify them.
About the only thing you can’t do is ignore them.
      Because they change things.
 
They invent.    They imagine.    They heal.
  They explore.    They create.    They inspire.
    They push the human race forward.



Maybe they have to be crazy.

How else can you stare at an empty canvas and see a work of art?Or sit in silence and hear a song that’s never been written?Or gaze at a red planet and see a laboratory on wheels?

We make tools for these kinds of people.

While some see them as the crazy ones,
   we see genius.

Because the people who are crazy enough to think they can change the world, are the ones who do.

Experimenting with Hypocycloids (Diversion VI)

I fascinated and treated myself with the simple trigonometric functions that I was working with previously just to relieve my stress after having finished a rigorous monthly data summary and report back from work. I never knew someone from Browny-knows-where reminded me of the very entertaining spirograph! Yes, a spirograph - it comprises a set of small, plastic-made wheels of different sizes and two large rings with teeth on their inside as well as outside rims which anyone can basically use to draw families of hypocycloids and epicycloids. The toy was introduced in the western culture in 1970’s; and, though I live in a third world country, I was fortunate enough to have a grasp on this wonderfully educational graphing toy - I quite remember my elementary public school library had me borrow a set one time. 

In this photo, I constructed hypocycloids by using the same smoothed-line XY-scatter plots easily available from Excel. The equations are easy and how selfish would I be if I don’t post them here?!

OK, here they are:

x(Ɵ) = r(k-1)cosƟ + rcos((k-1)Ɵ); and

y(Ɵ) = r(k-1)sinƟ - rsin((k-1)Ɵ).

I decided r to be equivalent to 1 just for ease of encoding and let k be any number (it’s actually the ratio between the radius of the bigger wheel against the smaller one). For the case of my Diversion VI photo, I simply selected the values 7.2, 4, 2.1, and 6.

Now, I’m off to the market to find myself one of those spirographs. Excel must make the plotting easy, but the real toy offers more.
