  1. Re:Cause and Effect? on Super Scrabble Players Have Unusual Brains · · Score: 2

    One adapts to their environment, and playing Scrabble requires you to see words differently than most.

    Indeed. The development of this ability in hardcore Scrabble players is similar to the Tetris effect.

  2. Re:Are you a salesman? on The Mathematics of Lawn Mowing · · Score: 2

    This is not quite equivalent to the TSP. TSP tries to find a minumum weight hamilton cycle, which does not allow repeated vertices. In the problem here, they are allowing vertices to be repeated, but they are trying to minimize the number of repeats. Also, the graph obtained by overlaying the triangular grid might not be hamiltonian.

    That said, I suppose you could translate an instance of this problem to the TSP by doing something like adding weighted edges between nonadjacent vertices, and letting the weight of each new edge uv be the distance between u and v in the original triangular graph.

    Curses, will have to think up a better plan.

  6. Monopolistic advantage. on Consumer Reports Gives AT&T Lowest US Carrier Rank · · Score: 1

    Different carriers are better in different areas of the country. Anecdotally, in my experience AT&T is great in the southeast and Sprint sucks. In Northern VA it's the opposite.

    Since the iPhone is only available with AT&T, some people who would go with a superior carrier in their area will opt to go with less-desirable AT&T because they want the iPhone. Those who want a different phone or don't care about their phone's brand are going to tend to go with the better carrier, and the data will reflect all of this.

  7. Reminiscent of Freeman Dyson on Charles Darwin's Best-Kept Secret · · Score: 1

    This makes me think of some of the subject matter of Freeman Dyson's "Disturbing the Universe." I'm thinking in particular of the section where Dyson compares what he calls "green" and "grey" technology. Currently we're using grey tech to go to space, where people live in cans and everything requires "unnatural" sources of energy to maintain its existence. Dyson talks about how genetic engineering, adaptation, and evolution could help us adapt to living in hostile environments (like Mars or the moon) in a way similar to how man has adapted to less harsh environments in the past--things like people in high altitude areas developing greater lung capacities.

  8. Re:Can't enforce what is ignored. on Building a Traffic Radar System To Catch Reckless Drivers? · · Score: 5, Funny

    ..., but a citizen wants to start his own enforcement. Yeah, I see this working out.

    Yeah, it will. I saw a movie like this once. I think it had Charles Bronson in it.

  10. Re:"Presumption of innocence"? on Tennessee Town Releases Red Light Camera Stats · · Score: 2, Insightful

    Some states are considering banning red light cameras altogether, so there is clearly plenty of cause for concern about the issue.

    At least one state has already done it.

  17. Re:One word.. on Dirty Coding Tricks To Make a Deadline · · Score: 1

    Here's an example. I wrote a program that did a brute-force search for partition of a set into special subsets. Each element of the set was indexed by a 5-tuple, so the program used five for loops to iterate over the 5-tuples. Each time it found a 5-tuple that was compatible with the working partition, it adds it to the partition and continues searching forward from there.

    Each time the search reached a dead end, it would have to back up. Backing up involved tossing the last subset that was added to the working partition and resetting the five variables to match the next 5-tuple after the one that was tossed. The easiest way to do this was to manually reset the five variables and then jump back into the middle of the nested loops by using a goto statement.

  18. Re:Heat & A/C on Chevy Volt Rated At 230 mpg In the City · · Score: 1

    I drive a 2007 Prius and I I live in Georgia, so I run the AC practically all the time. I reset my mpg monitor each time I fill up my tank. The average is pretty much always between 44 and 50, depending on the type of driving I've done. The AC does not cut on and off while driving. If I leave the AC on for a long time while sitting still, the engine will cycle on and off charging the battery.

  20. Re:Surprised? on Teen Diagnoses Her Own Disease In Science Class · · Score: 1

    You can add a 4th to that mini-study. It took a few years of being treated for GERD, H. Pylori infection, and a few other things before I was finally diagnosed with gastroesophageal crohn's disease. I went through the same thing you described above. On separate occasions I took combinations of antibiotics, reglan, H2 blockers, and proton pump inhibitors. Each one helped to temporarily ease things a little, but never made the problem go away. I was finally diagnosed after exploratory surgery.

  21. Re:There is always an easier solution... on University Gives Away iPhones To Curb Truancy · · Score: 1

    "University is optional, paid for entirely by the attendee"

    I don't know where you live, but at public universities in the USA tuition only makes up part of the amount. The rest is paid for by the state, so when students slack off and fail classes, they are wasting taxpayer money.

  24. Re:HAHAHAHA on Oprah Sued For Infringing "Touch and Feel" Patent · · Score: 1

    I doubt she will settle, seeing how she dealt with the cattle farmers who sued her in the 90's. On the linked page, Oprah says that the 1998 lawsuit "will not change the way I operate. It has made me even more fervent in my desire and intention to bring information and enlightenment and encourage people in ways that I see fit." That bodes well for this lawsuit.
