Economists - FTW!

From SMBC , we have the clearest depiction of the difference between Normal and Economist type humans that I have seen in quite a while. (Zach Weiner is a genius...)

Where to eat in Italy (Liguria Edition)

Image
View Where to Eat in Liguria in a larger map Liguria - also called the Italian Riveria, is the area around 80 miles or so on either side of Genoa.  The actual riviera part is not all that interesting, its the hills and mountains that abut the riviera where all the fun happens, and where you'll find some quality non-touristic dining experiences. And, as a key point, if there is one place that you should go to in Liguria, it would be  Osteria Enoteca Baccicin du Caru outside Genoa (more details below).  Oh, the rest of the places I've listed are great, but this, my friend, is destination dining .  Make a point of it, and fit it into your travel plans... THE BOOK   David Downie :  The Terroir Guides:  Food, Wine, The Italian Riviera & Genoa . David is our patron saint when it comes to Italian food.  We ate our way through Liguria based on his book 'bout that area, and thanks to him, have had some of our best dining experiences ev...

CPU Utilization in Erlang R15B02

Image
Rickard Green makes an interesting point on the erlang-questions mailing list regarding CPU utilization in Erlang R15B02 Regarding increased CPU utilization in R15. When schedulers run out of work, they busy wait for a while before going to sleep. Waking up a busy waiting thread is much faster than waking up a sleeping thread. Due to the rewrites of memory allocation in R15, schedulers are more frequently woken, which cause more busy wait, which in turn cause an increase in CPU utilization when schedulers frequently run out of work (you will at least see some decrease of CPU utilization due to this in R16). When not running out of work there will be no busy wait at all. That is, the increase in CPU utilization does not translate into loss of performance. The busy waiting is there since it shortens the average time to wake up a scheduler, and by this reduces average communication latency between processes. Depending on application the reduced latency might also translate into imp...

Creationism - FTW!

Image
Doonesbury w/ a riff on the idiocy associated w/ Creationism . Which brings to mind Billy Nye's (the Science Guy) take on all this "I say to the grownups, 'If you want to deny evolution and live in your world that's completely inconsistent with everything we've observed in the universe that's fine. But don't make your kids do it." [...]"We need them. We need scientifically literate voters and taxpayers for the future." Because, seriously, if you insist on raising your kids to be morons, Who is going to take care of you when you get old? P.S. : Saying " I don't care, I'll be safe due to the Rapture " is not a reasonable response.  Go aways. P.P.S. : Saying " I don't need anyone, I can take care of myself when I'm 93 " is even less of a response...

MySQL vs Postgres (vs MongoDB)

Image
Chris Travers has a fairly nifty article up titled O/R Modelling interlude: PostgeSQL vs MySQL , where-in he makes the claim MySQL is what you get when application developers build an RDBMS. PostgreSQL is what you get when database developers build an application development platform. This isn't really flame-bait - its intended as a statement to show how people approach arguments (flame wars?) about MySQL vs PostgreSQL.  To paraphrase Chris, MySQL has been massively disruptive because it tends to really, really look at the world from a Use Case perspective, answering the questions " What problem are you trying to solve ", while Postgres has been massively disruptive because it tends to look at the world from a theory perspective, answering the question " How should the database work in the solution " I'd add MongoDB to this mix though, and extend the above quote to say MySQL is what you get when application developers build an RDBMS. PostgreS...

Cameras to watch Speed Cameras - The Awesomeness is making my head explode!

Image
I, seriously, could not make this up.  From Ari Ashe at WTOP , we have this gem - New cameras to watch cameras that watch you Many people find speed cameras frustrating, and some in the region are taking their rage out on the cameras themselves. But now there's a new solution: cameras to watch the cameras. One is already in place, and Prince George's County Police Maj. Robert V. Liberati hopes to have up to a dozen more before the end of the year. Got that? And, in case you are wondering about why the speed camera can't take the pictures itself, it isn't about people sneaking up from behind   Speed cameras themselves can't be used for security because under Maryland law speed cameras can only take pictures of speeding, says Liberati.  The sheer insanity of this whole process is mind-boggling.  Me, i'm waiting for when they put up cameras to monitor these cameras :-)

Hackers and Obsolescence

Bloom County said it all, a long time ago Hackers, as a rule, do not handle obsolescence well. Mind you, the unsaid caveat should be "Unless you are a fanboy " (ref: the latest MessiahPhone)
