Map shortage in the USA?

Filed under: Funny people — Daniel Lemire @ 21:35

I was unaware that the USA could not afford enough maps. I suggest the rest of the world teams up: if you send just one map to the USA, then you will have made a difference.

I have decided to do my part:

Get into pay sites for free as a Googlebot

Filed under: — Daniel Lemire @ 14:39

This trick is very clever: many sites limiting access to documents, let Googlebot (Google’s spidering agent) through. I think this is the case with some IEEE archives. So, you can simply tell your browser to identify yourself as user agent “Googlebot/2.1″. Voilà! You can go where Google can go. What a beautiful hack!

With Firefox, you can get this result with the User Agent Switcher.

More details are available on Pinguy’s website.

Where the progress is happening in hardware

Filed under: — Daniel Lemire @ 8:56

While everyone is getting excited about multicore systems, something else is happening:

I just ordered two new 500 GB drives to replace the failing and failed 250 GB drives. Both 500 GB drives cost almost exactly the same as one 250 GB drive did three years ago. That’s progress. (Source: Harold)

Not only are our computers able to do more things at once, they can also do it over much more data.

I own a couple of 500 GB drives with nothing on them. I could easily buy much more. I own a couple of multicore processors that are idle. If it were important, I could buy more machines too. I am sure most people are like me.

In some respect, we no longer have scarcity of storage and CPU cycles.

Super Flash Mario Bros

Filed under: — Daniel Lemire @ 20:23

My wife loved this: Super Flash Mario Bros. Flash games can really be impressive. This one looks and feels very much like the Nintendo original.

Me? I could never figure out the appeal of a game like Mario. Somehow, I always end up falling into nothingness well before the first level is over. Where do all these Marios end up after falling for a long time? Wouldn’t the hole eventually fill up with corpses? What about the smell? Or are we supposed to assume that the hole has infinite depth? But can gravity and holes of infinite depth mix? Wouldn’t this be very unstable? Wouldn’t the dirt keep on falling in these holes? What does he eat? Turtles maybe? Uncooked turtles?

Teaching radical novelties

Filed under: Academia/Research — Daniel Lemire @ 10:02
Universities should not be afraid of teaching radical novelties; on the contrary, it is their calling to welcome the opportunity to do so. Their willingness to do so is our main safeguard against dictatorships, be they of the proletariat, of the scientific establishment, or of the corporate elite.

0xFFFFUL

Filed under: — Daniel Lemire @ 20:19

I actually had to type 0xFFFFUL in a piece of code I just wrote.

This is exactly why ladies stay away from Computer Science, and young geeks can’t get a date.

Weighted Slope One in Haskell

Filed under: — Daniel Lemire @ 7:57

Bryan implemented the collaborative filtering algorithm Weighted Slope One in Haskell using only 29 lines of code. I must say, I am impressed.
