I've got the MCE remote running already. Here's my desired setup: Cable -> DCT700 -> PVR500
I know I'll need a second box for the other tuner and that's fine. I'll have to figure out how to get another script working with the second IR port on the receiver instead of the first.Newegg picture for reference.
The script in the link I provided has a lircd.conf for the Comcast remote instead of the MCE remote.conf I'm using. The channel change script is a little more involved than what I need it for since we also have an HD box that we can use for most Comcast needs (on-demand, etc) and the script looks to be heavily tied into the Comcast remote. I went with the script here for the channel change. I then changed the words one, two,... to 1, 2,... That is what I hope will work. I'll try it out tonight.
I'm not really a Linux user but I was building a tivo box and the/. talk on Ubuntu spurred me to give it a shot (I like it a lot). I saw how much easier it is to install remotes in Gusty than in Feisty (not as terminal heavy, a preference thing). But how easy is it to get digital cable boxes integrated and working? I have digital cable and getting that working is a big thing for me.
I think I've got everything in Feisty where it needs to be but I just have to bum the coax to test if it works tonight. Otherwise, I'll have to try to figure it out. There's the guide on adding the DCT700 remote but it looks like I'll have to use the Comcast remote and I'd rather use the MCE remote that came with the Hauppauge card (thinking beyond Comcast).
That's pretty much the same problem I've had with the episodic gaming. They promised new content every 6 months, which was nice since I got to play new parts to the franchise every 6 months instead of every two years. I always considered the perk being that I never really forgot about the series and kept wanting to play.
Like you, I always saw episodic content in the sense of we release episodes on release A. Keep working on release B and integrate it for a major release (like HL3). I think Valve lost focus on what they needed to do to keep episodes releasing on schedule. Perhaps someone kept saying that major changes were almost done or adding them would make this XX% better. I suppose it could be construed as mismanagement since I think you have to reign that sort of thinking it if it's causing problems.
But since I'm not in charge of one of the most successful franchises, I'm not really in a position to do anything but give my opinion and think it's good. Perhaps if I were their shoes, I'd know something different.
GE90 fan spool spins at around 2500 rpm with a fan of diameter around 135 inches. Do the math on the energy involved when a blade is released and the resulting instability of the remaining fan. Notice that the casing doesn't explode into pieces and send shrapnel everywhere. Always laugh at anyone that talks shit about composites.
I probably have more foes than friends Since I assume probably suggests a likelihood of 60%, I declare you officially wrong because I decided to investigate since I'd friended you a while back.
Fans v Freaks: 622 v 276.
This is what a boring day of work gets you. Take that. It's ripe for the taking. Oh yea, so so fresh. God I'm so bored...
I just tried it ago five minutes ago. As soon as I started streaming, all my cable in the house caught fire and my house burned down. Then a Microsoft guy came and peed on the ashes. It was awful.
I really like Google maps except for the fact that my street has problems in their software. The features are good enough and do what I need to but not having my street bugs the hell out of me. There's also no way to talk to them about it so I can let them know.
Here's the problem: I live on 'Center St NW' and this matters because there's another 'Center St' in the city. When you use NW, you end up being shown 'Northwest Dr NW'. But when you spell out Northwest, you end up at my address. Unfortunately if you save the location as your default, it ends up being saved as NW and results in nothing near where I live.
Now Google maps didn't used to have this problem with my address so something changed with Google. I checked Yahoo maps and Mapquest and they use the same data for their maps - NAVTEQ. But the can find my house on their maps and the NAVTEQ data isn't messed up (you can check theirs online). So the onus is on Google to fix it but I have no way to do so.
It's not a big enough of a negative to turn me away but it still pisses me off every time I use them.
"There's one wavelength that gets everybody," says IOS President Bob Lieberman. "Vlad [IOS top scientist Vladimir Rubtsov] calls it 'the evil color.'" Perhaps I misunderstand the functionality of the device because the article says earlier that the device works as:
The handheld device using light-emitting diodes to emit super-bright pulses of light at rapidly changing wavelengths, causing disorientation, nausea and even vomiting in whomever it's pointed at. Bob claims that Vlad says there's an "evil" color that gets everyone. But the description of the device uses pulses of light at varying wavelengths to cause the effect. So if there's only one wavelength, then why do they need to change the light?
Couldn't I just pull up into Home Depot's color center and have them make paint in the "evil" color and use it for whatever (pranks, revenge, robbery)?
But I wonder when "geeks" are so hostile towards any tech company, game related especially, without that multi-million dollar veneer. It's not until an "indie" gets published by Sony does it become hip enough to look into (Guitar Hero, Katamari, etc) I'm hostile because I would love to see information on this game instead of a bullshit promo. There is no useful information in this game description. I know it's an introduction to a concept but their approach is far too pretentious for me at this point. I want more information than a marketing profile... give me information that I can actually get interested in... more than a promo and two pictures (one is a conceptual picture)
Your earlier comments share my perspective as well. My point is simple: give me information in your game announcement. Simply claiming that "THEY" will dominate everything is not enough! I don't want marketing BS hype; I want something to get me excited in your IP. Bioshock, Spore, The Witcher.. these games interest me, they make me excited about the next timeframe until they exist. "THEY"'s information makes me bored with marketing speak. It's the equivalent of them depositing "stuff" into a bag and trying to sell me bags of gold.
I consider myself open-minded on entertainment (I've reached the point of TV show concepts I hate result in my watching them and end up enjoying them.. ie: Burn Notice, BSG, Psych). But I want to see something about what is going on. I understand that they want to keep some secrets but I don't want promises or guarantees; I want to see gameplay and concepts when/as/while they are developed. I want to see reasons for delay, example: Spore is delayed because of problem X and here is an example. I can see where they are struggling and why and enjoy their work to improve their process. I want to see something about this game they are trying to sell me conceptually. If you give me marketing speak, I will give you hostility; I don't consider myself a number but someone you have to actually earn as a customer.

Parent essentially sums some up what I was going to say.
EA developed their understanding of the video game market and planned accordingly. They saw the rise of graphic dominance and hardcore gaming dominance. They may have tried to figure out how to pull in people who don't play video games but completely abandoned that approach. Given they frustration at pulling in non-gamers, I'm not surprised that they were caught off guard.
However, I think it was a failure on their part not to realize what was needed to capture the market share of non-gamers. Perhaps they might have sat down and realized that it was a hardware barrier and not completely a software barrier. And had they done so, there was no reason not to stand behind the Wii. A new controller style that non-gamers could relate to. A shift in gaming interaction. Getting in on the ground floor and staying ahead of the competition.
Could they have seen the Wii coming? Perhaps. As the parent says, no one really sees disruptive technologies coming unless you know the market. But even then, they may still backfire and end up unadopted. EA could have poured all this money into developing for the Wii and it could have flopped. I suppose they look stupid now but perhaps it made more sense then. Maybe they could have done some real options analysis or something similar to see value in developing for the Wii.
King-manic pretty much has it down. I've seen more excitement in the Wii from all my friends that rarely or don't play video games than anyone else. I haven't played it in a while mostly for the following reason and a general lack of time with 3 classes in the summer.
Right now, single player is a drag but I need to get a couple Wavebirds and play some Gamecube games I haven't played in a while or at all. I loved Zelda and enjoyed Heatseeker. I've heard much fun about Mario Party and Rayman is a blast with groups. Once the Wii picks up some more group games with a couple solid single player games, I think things will be back on the up-and-up.
But if you aren't interested in their controller aspect, then you really aren't going to care for the Wii. Honestly, I just don't think more games or new games will get you excited about the system. I don't know your gaming interests so I can't really say if you'll be happy with new developments on the Wii.
Now if only I had the time to play games.... (stupid classes)
Aren't these more teasers rather than previews? Sure I'm excited to see Fallout 3 footage but honestly, these things seem like scripted presentations that they want to use to show off something in the games instead of a close to finished product.
Perhaps I'm just being picky on nomenclature but I see previews as something in the beta tests or a version that's almost ready for consumption. Even almost ready to send off for reviewers. On the other hand, teasers are things like this where they show off some features in the game or provide insight into the game's story and concepts.
In short: Teasers create interest and build hype. Previews show off ready product (or almost) and let people know they are almost ready for you.
CO2 production for commercial aircraft is currently not regulated by the UN group ICAO-CAEP (International Civil Aviation Organization)-(Committee on Aviation Environmental Protection). Since CO2 is directly associated with fuel burn, operators (airlines) have their own incentives to directly reduce CO2 emissions. The techniques discussed in the article would be applied on the operations side and not the manufacturers side so realistically, there would be no serious loss.
Although I'm willing to agree the models might not be perfect predictors of future trends, I'd rather we reduce the fuel consumption of aircraft simply from an energy conservation perspective. But that's my biggest concerns personally.
Something that will really be a problem with these extended delays is that Spore could potentially drop off my map. I'm generally really hyped about Spore and I'd almost be willing to give my first born child (if ever that happens...) to play it now.
So you delay the game and I want the bugs to come out so it's fine. Delay it again and I suppose there's more unforeseen problems. Another delay and I say "it's Maxis so they want to get it right." Eventually, the news gets old and I see it as "oh, big surprise..." and eventually stop caring.
Spore is a game with such huge potential. Everyone I've talked to is excited about the game, especially friends that don't play them. But come on, give us some details as to why. Don't be like Bioware and say it'll be done when it's done like they've done with Dragonage. I know that you can't give all the details away but you can use these delays as chances to discuss some of the features of the game. "We caught a snag in the walking model for the creatures and certain makes will be unable to move. And here's an example of what we're talking about." This is what we need, not just reports of the game's delayed, goodbye.
lommer gave a pretty solid explanation of what is going on with thrust reversers.
Reversal depends on the engine type (turbojet, turbofan, etc..) and the manufacturer. I've seen some information that one manufacturer blocks the bypass nozzle and redirects the flow out to reverse thrust. Pretty much, the fan still operates as usual but the bypass air is used and not the core flow (through the burner). It sounds like you have some mild confusion as to engine classes/terminology so I'll provide some details that might help clear things up plus a couple decent links with flowpaths.
Turbofans are used nowadays on commercial aircraft because they have a significantly better fuel consumption. Engine thrust can be calculated using Thrust = mass flow * (jet velocity - intake velocity)
You have two ways of increasing thrust: you can have a small mass flow and have a large Vjet (turbojet) or you can have a large mass flow and smaller Vjet (turbofan). The only way to produce a large Vjet is to burn more fuel. The term bypass ratio is used to compare the bypass air / core flow. The GE90 sports bypass ratio of 9. Bypass is difficult to deal with since increasing bypass ratio will reduce fuel burn BUT when in cruise, they have a ridiculous profile drag.
Ultimately, engine design is a complicated trade with multiple attributes at different mission segments matching vehicle thrust requirements, vehicle dimension needs, field conditions, maintainability, and noise and emissions regulations just make up a handful of the design concerns. So next time you fly, try getting a seat behind the engine and try to check things out. The design process is really quite amazing.
I'm going to stop here since I've written a lot. I'm just excited about having insightful things to say for once.
Spot on. I really think this country needs a hard reset or we are going to collapse hard. Don't be surprised when it happens in the next couple of generations.
A ramjet relies on the fact that if you fly fast enough to start with, you get air pushed into the engine anyway. (Plus some clever design of the intake so the flame doesn't go in both directions.) Not necessarily. The ramjet inlet's design is such that the air is compressed through ram compression, essentially the air is compressed as it is slowed down. There really isn't any clever design on the inlet. The pressure in the inlet area is greater than the that of the combustor and so long as that is true, no flame will come out. You're essentially correct but I just wanted to nitpick.
Explaining the turbojet is easier after explaining the ramjet. Ramjet performance suffers below Mach 1 because you can't get enough compression for efficient combustion. The turbojet adds a compressor to add work to the flow so you can get the desired pressure ratio coming into the burner. Then you have to go through the turbine such that you can power the compressor.
Engines with compressors are far more interesting as they can be pushed to the point (whether by power setting or flight condition) such that the compressor can stall and flame will shoot out the front of the engine. It's something pretty important in compressor design since they operate with an adverse pressure gradient (pressure out > pressure in). This is why you see compressors with 10+ stages powered by only 1-2 turbine stages. It's really quite interesting.
You basic principle explanation isn't great for non-engineers. Try using "Suck, squeeze, bang, blow." I explained that to some friends of mine and they were way more interested. They not only laughed but they then wanted to hear more detail. But solid explanations on your part, I just wanted to nitpick a couple things since I'm a propulsion guy.
My only beef with the Gamecube controller is the placement of the Z-button. I really liked the Z-button placed under the controller on the N64 and had the Gamecube controller done that, I would support it hands down as the best.
The list is pretty solid and even though I dislike the Xbox and 360, I think the 360 controller is pretty nice. Honestly, my only beef with the list is the N64 controller. As other posters have pointed out, you can't use a third of your controller at a given time. I wish keyboard and mouse could be on the list but no console implements them and a PC isn't considered a console. I like the Wii's controller but I think it's still young and we're going to see a lot of improvement in the next year on its implementation in games.
I wish they'd wrap up the show and stop it when they've run out of material and said what they want to say. But even the best show is doomed to drag on our screens, while the rating brings in ad money. It's so sad. Funny... you should listen to the podcasts. Ron Moore says that many times. He has two last things he wants to tell. Either they were going with 2 13 episode seasons or 1 22 episode season. They don't want to milk it either but they want to end it correctly. Next season is the last season from what the podcasts have said.
With falling viewership (biased against tivo users) and the foolish move to Sunday night, I can't see them extending the show to a fifth season. But with all this recent news, fans may do some ridiculous things resulting in something ridiculous happening at scifi.

Could be Dune too. But I never got into Dune. Perhaps I will find the time after I finish grad school.

Turbojet describes a simpler turbomachine engine -> inlet, compressor, burner, turbine, nozzle http://www.aerospaceweb.org/question/propulsion/j
Turbofan describes a more complex engine -> inlet, fan, splitter, compressor, burner, hp turbine, lp turbine, nozzle... splitter, bypass duct, bypass nozzle http://www.aerospaceweb.org/question/propulsion/j
Turbofans are used nowadays on commercial aircraft because they have a significantly better fuel consumption. Engine thrust can be calculated using

Spot on. I really think this country needs a hard reset or we are going to collapse hard. Don't be surprised when it happens in the next couple of generations.
Explaining the turbojet is easier after explaining the ramjet. Ramjet performance suffers below Mach 1 because you can't get enough compression for efficient combustion. The turbojet adds a compressor to add work to the flow so you can get the desired pressure ratio coming into the burner. Then you have to go through the turbine such that you can power the compressor.
Engines with compressors are far more interesting as they can be pushed to the point (whether by power setting or flight condition) such that the compressor can stall and flame will shoot out the front of the engine. It's something pretty important in compressor design since they operate with an adverse pressure gradient (pressure out > pressure in). This is why you see compressors with 10+ stages powered by only 1-2 turbine stages. It's really quite interesting.
You basic principle explanation isn't great for non-engineers. Try using "Suck, squeeze, bang, blow." I explained that to some friends of mine and they were way more interested. They not only laughed but they then wanted to hear more detail. But solid explanations on your part, I just wanted to nitpick a couple things since I'm a propulsion guy.
My only beef with the Gamecube controller is the placement of the Z-button. I really liked the Z-button placed under the controller on the N64 and had the Gamecube controller done that, I would support it hands down as the best.
The list is pretty solid and even though I dislike the Xbox and 360, I think the 360 controller is pretty nice. Honestly, my only beef with the list is the N64 controller. As other posters have pointed out, you can't use a third of your controller at a given time. I wish keyboard and mouse could be on the list but no console implements them and a PC isn't considered a console. I like the Wii's controller but I think it's still young and we're going to see a lot of improvement in the next year on its implementation in games.
With falling viewership (biased against tivo users) and the foolish move to Sunday night, I can't see them extending the show to a fifth season. But with all this recent news, fans may do some ridiculous things resulting in something ridiculous happening at scifi.
