The world’s most brilliantly pointless street flyers.
The hand-posted flyer is perhaps the cheapest way to spread the word about lost dogs, found cats, and creepy looking men offering low-cost guitar lessons. But most of the time, those flyers serve as nothing more than reading material for people waiting to get into a bathroom or on a bus. The flyers collected here acknowledge this reality, and they respond by trying to do nothing more than entertain whatever pair of eyes happen to be aimed in their direction. You now have no excuse for wasting all your time on the Internet when it’s perfectly clear you could be wasting paper out in the real world.

You can’t squeeze a dime out of the PC market. The race to the bottom finally went thud. The future is bleak for PCs. Sell off the PC division now while the asking price is good. Sad move, but prolly the right one.
I’ve said this before, but thought it was worth repeating: It’s in Apple’s DNA that technology alone is not enough. That it’s technology married with liberal arts, married with the humanities, that yields us the result that makes our hearts sing.
And nowhere is that more true than in these post-PC devices.
And a lot of folks in this tablet market are rushing in and they’re looking at this as the next PC. The hardware and the software are done by different companies. And they’re talking about speeds and feeds just like they did with PCs.
And our experience and every bone in our body says that that is not the right approach to this. That these are post-PC devices that need to be even easier to use than a PC. That need to be even more intuitive than a PC. And where the software and the hardware and the applications need to intertwine in an even more seamless way than they do on a PC.
And we think we’re on the right track with this. We think we have the right architecture not just in silicon, but in the organization to build these kinds of products.
And so I think we stand a pretty good chance of being pretty competitive in this market. And I hope that what you’ve seen today gives you a good feel for that.

The Lepton Photon Conference begins on Monday. This is a biennial conference and this year it is being held at the Tata Institute for Fundamental Research in Mumbai, India. During the years that Lepton Photon is held, it is the premiere conference for releasing new experimental results. This being the full year of LHC running, everyone is anticipating the results that are expected to come out.
Three weeks ago, the first searches for the Higgs came out of the LHC and they showed a subtle, but striking excess for a Higgs mass of 145 GeV at both the ATLAS and CMS detectors. At Lepton Photon they will present a combined analysis for the first time and potentially update their analysis to include an additional 50% more data. The talk about the Higgs boson will occur Monday morning India Standard Time (GMT+5:30).
When colored particles (e.g. quarks and gluons) are produced they try to cast off particles through radiation. These particles then further radiate. This cascade of particles is called the parton shower. The end of parton shower is a grouping of particles that are near each other and are called a jet. Quarks and gluons typically split 10 to 20 times.
Gluons tend to split more than quarks and thus produce wider jets. This is one way we try to identify if a new particle is a quark or gluon. So far, we aren’t very good it at it. We only get it right 70% of the time.
The above picture shows one way a gluon can parton shower. It’s shown using double line notation.
Double line notation lets you represent the color flow of particles. Quarks are single lines with their arrow going forward while antiquarks are single lines with their arrows going backwards. Gluons are represented by two lines: one going forward and one going backwards.
The figure shows a gluon splitting 4 times.
- A gluon splitting into two gluons
- A gluon splitting into a quark-antiquark pair
- A gluon splitting into two gluons
- A quark splitting into a quark and a gluon
