Pirates of the Caribbean, On Stranger Tides

2011/05/31 By staze

Last night Tara and I saw Pirates of the Caribbean, On Stranger Tides. And by and large, it pretty much lived up to the franchise that has happened since the original (also taking into account distance from the original. If the original was a 4.5 star movie, the 2nd was a 4, the 3rd was a 3.5, etc). While we did miss Keira and Orlando, they were replaced with other characters that were “okay”. All and all, the movie felt like it had too many writers, and that rather than writing a real plot, they just threw in action. So really, it was more an action movie than the previous movies of the series.

It was visually very attractive, and I personally only had one point where I completely lost my suspension of disbelief… they were in a forest of Giant Bamboo…. which isn’t native to Florida (where the fountain of youth is supposed to be), and wouldn’t have existed during that time in Florida.

I also didn’t find myself laughing during any part of the movie. I do remember doing that when seeing the previous three movies. So really, the movie was “okay”. I’d recommend waiting until the movie is at the cheap theater before shelling out the money to see it, or wait until it’s on DVD and get it via Netflix. If you want to see a movie, go see Thor. It’s really the only other current movie I can recommend (haven’t seen any other current movies).

The Portal problem

2011/05/27 By staze

After playing Portal 2 co-operative through, a friend and I were chatting and realized a bit of an issue with the physics in Portal, and neither of us were sure if this is something Valve even thought of when producing the games.

The graphic to the left ((images for this post were generated with Omnigraffle using a stencil I produced from vector images obtained from here. All are unofficial)) shows a situation where in Portal 1 and 2 ((Portal is a registered trademark of Valve Software)), you could put a portal on the ceiling, and one on the floor, and basically fall “forever”. But, for those that have done it, you’ll remember that there was a terminal velocity that was reached where you couldn’t fall any faster. Terminal velocity being the speed at which the air resistance of the falling object is great enough to counteract the gravity that’s pulling the object down. And that rate changes based on the shape of the object (so a person falling with hands at his/her side, legs together, pointed down, will fall faster than someone falling spread out, chest down).

Moving the modem

2011/05/23 By staze

Since moving into my home, I’ve had my cable modem in our office. A room above our garage that has coax run to it from the garage, which is where the CATV coax enters the house. Coax enters the house through a wall, goes into a splitter, and heads from there up to our office. Total run length from the splitter is about 30ft. With the modem in the office, and then in the garage, the data for the modem follows (Update 5/26/11: After a couple days, the signal levels changed a bit in its new location. I’ve found online that 6 dBmV is actually a bit on the high side for signal strength, but within acceptable limits):

Office Garage Garage 2
Downstream Freq 567.00 mhz 567.00 mhz 579.00 mhz
Downstream Power 3 dBmV 4 dBmV 6 dBmV
Downstream SNR 36 dB 36 dB 35 dB
Modulation QAM256 QAM256 QAM256
Upstream Freq 32.400 mhz 32.400 mhz 22.800
Upstream Power 44 dBmV 43 dBmV 42 dBmV
