Doh! My memories of arcade Pacman must be fuzzy or maybe it was all the Street Fighter in between where you did need diagonals for the sweep moves. Did it have a 4 way restrictor? A four switch joystick can still take diagonal inputs. Diagonal up and left is just the up and left switches pressed at the same time.
Now that I think about it, the problem with the digital gamepads was that they're very sensitive to slightly diagonal inputs. If I pushed even 10-15 degrees off the compass point it would register a diagonal input with the result of Mario or Pacman getting stuck.
The main reason for the higher efficiency of diesels is the higher compression ratio, over twice the C/R of a gasoline engine. The theoretical Carnot efficiency of a heat engine is directly proportional to the compression ratio (actually the expansion ratio) and the difference between combustion and exhaust temperatures. More diesels would definitely go a long way in conserving oil. The Dodge Sprinter is a full size van that gets 30MPG.
I guess your habit is to return the stick to center when you're moving in one direction then push the stick in the direction you want to go at a corner. My habit was to hold the stick in the direction I'm moving e.g. right then transition diagonally to up. It wasn't a problem in the arcades, but it gets stuck in MAME.
That's true. Motorcycles aren't as safe as cars, but the risk is managable if you make the effort. Except for public transportation pretty much any alternative to cars is going to be less safe than cars if you're sharing the road with them. Two simple reasons for that:
- Size. Anything more efficient than a car will probably be smaller than a car. In a collision with a car, the smaller alternative will lose. That's true whether you're on a motorcycle, bicycle, Segway, oversized golf cart, or on foot in a crosswalk.
-Cars are sold by the millions to minimally trained operators. They're as idiotproof as it gets. Motorcycles are more like snowboards and inline skates. Not idiotproof and they require considerable skill and practice to operate safely. If you can't deal with that motorcycles aren't for you.
My biggest complaint about Pacman in MAME is not responding to diagonal inputs correctly. E.g. if I'm going right and want to go up at the next corner I'll push the stick diagonally up and right, but it doesn't read the up input and keeps going right. It seems to mess up more on digital joysticks and less on analog joysticks. Anyone else noticed this?
"What economical solution do you propose to fix this?"
There's enough coal to last a hundred years, maybe a lot more. I think given the choice of going back to preindustrial society or burning the coal, we'd burn the coal. We can do things like launch a solar shade to the Lagrange point to cool the earth, but it sounds like a dangerous, desperate measure to me. The effects on climate can be unpredicatable to say the least.
In places with air pollution problems, summer blend gasolines or reformulated are formulated for lower vapor pressure to reduce evaporative emissions. They don't use the summer gasoline in the winter because the lower vapor pressure makes it hard to start in the cold.
In LA, premium is $2.50 plus or minus 5 cents. I'm just glad I don't live 50mi from the office like some people here. The problem in California isn't just the price of crude, but refining capacity too. All our refineries run flat out all summer just to keep up with demand. Nobody's building new ones. Shell even wants to close one in Bakersfield this year. Can you say hello $3 a gallon? Hey, at least my motorcycle gets 40-45MPG.
At least you northerners have a legitimate complaint about the weather. Here in LA, when I ride my motorcycle to work in 55deg weather everybody asks me if I'm cold on the motorcycle. Well actually yes, 55deg with a 60mph windchill can be pretty cold. It's called weather. That's what the jacket and gloves are for.
Thanks for the link. My linked article says 1.4W was measured from a laptop PC card. Apparently a CF or SDIO wireless card for PDAs will use a lot less power, but the problem is the same. An idle link uses almost as much power as an active link.
Toy is right. Besides the problem of roaming, power consumption is a huge problem with Wifi. 802.11b is a high bandwidth, long range (compared to Bluetooth at least) protocol. It consumes a lot of power just maintaining a link to the AP. According to this it consumes 800mW while idle with a link up, 950mW while receiving, and 1400mW while transmitting. Wifi might be practical for outgoing calls, but not the other way. You'd drain your battery ust sitting at a hotpot waiting for a call.
It's actually not that hard to find a T-mobile hotspot. There's a Starbucks practically on every block. The cost savings argument doesn't make sense though. $30 a month is only $5 less than my cell phone plan. Also, you'll still need a paid VoIP account (about $20 a month) to call regular phones, otherwise you'll only be able to call other IP phones. Free hotspots are harder to find. In my neighborhood there's one at the food court at the mall and another one at a fast food restaurant. Plenty of unsecured wireless APs on my street too, but the CF Wifi card on my PDA is too weak to connect to them.
Leela: "You can't just sit here in the dark listening to classical music." (classical music in the year 3000 = Sir Mixalot, Baby Got Back) Fry: "I could if you hadn't turned on the lights and shut off the stereo."
So use a pay phone. It's safer anyway because toll free numbers always get your caller ID even if you block it. Plus they actually get billed a surcharge to receive calls from payphones.
Much like a GPS attachment for a PDA, the advantage of this over a standalone GPS that the GBA already has a powerful CPU and good screen. Both are much better than you'd find in a low end GPS unit. That means the GPS attachment can be cheap and simple- just a GPS receiver chip and memory for the maps. You can get a one piece package by putting a CF card GPS into a PDA, but it just seems too expensive and delicate for outdoors handheld use. My Etrex Legend is waterproof and rubber padded. I'd have no problem using it on a bicycle, motorcycle or boat. The GBA splits the difference in cheap and rugged, and the page says they licensed the Navtech maps. You'd pay about $500 for the equivalent standalone GPS with color screen and maps.
If you want a handheld GPS to work with your PDA, just about all of them have a serial interface that can plug in to a PDA with an adapter cable (about $50). It's a cumbersome package though, better suited for car navigation than hiking. A handheld GPS with adequate mapping would be better for that. They all use proprietary maps though.
This won't be taking any iPod market share with just memory stick for storage. What do flash players cost now? Like $60? I doubt it'll play unprotected MP3 files. It'll probably make you recode everything to ATRAC just like the NetMD. Vapourware implies something new and exciting. A flash music player locked in to a copy protected online music store is neither.
You'd need root to destroy the system, read all the files, or install a rootkit to hide your tracks, but most worm writers don't really care about that. What they want is for the worm to spread itself and they want anonymous proxies to do their spamming, phishing and DDoS'ing.
That adds a few steps to running an attachment, but the worm writers are working hard against you. Netsky sends itself as a ZIP attachment, sometimes an encrypted ZIP to slip by virus scanners ("hey look at this! the password is foo"). So now from KMail you open the attachment in Ark. Now what do you suppose happens when you double click a.sh file in Ark (or Gnozip for that matter)?
The PIII was not a good match for RDRAM. RDRAM had a faster transfer rate but more latency than SDRAM. With the chipsets of the day (i815, Apollo Pro 133A, i440BX overclocked to 133) PC133 was faster in most benchmarks. See for yourself, Anandtech still has their article online. By the time the P4 rolled around, it was a better match for RDRAM. The i850 boards were significantly faster than the SDRAM and DDR boards of the day, but by then most people wanted nothing more to do with Rambus.
To some extent you can do that with design. Owners might be more likely to get attached to a car if it was cute (Mini) or so ugly it was cute (Element, Scion xB). They'd be less like to get attached to a boring looking car (Camry, Cavalier).
You don't need root to run a mass mailing email worm. If you could convince a user to run a trojaned executable, regular user permissions will do just fine. It could even open a spam proxy backdoor without root. All you really need root for in network code is for raw sockets and to listen on low TCP ports (below 1024).
Some email worms exploited an autoexecute from the preview pane bug in IE, but most of them were social engineering exercises in convincing the user to run the attachment. I think it's easy enough to launch an attachment in say Kmail or Evolution. The only challenge is delivering an executable that'll run on enough Linux machines (perl? bash? static binary?). The only reason we don't have a mass mailing Linux worm is because noone's tried it yet . It's not THAT hard.
Nouns just have gender in Latin languages. One of the first things we learned was that gender has nothing to do with the masculinity or femininity of the object. For instance, in French necklace is masculine (collier), but dynamite is feminine (dynamite). If you think that's confusing, try German with three genders: masculine, feminine and neutral.
Maybe for the race, but for training, runners can afford a little more weight to get more cushioning. Track shoes are very light and have little cushioning. You wouldn't want to train long distances in them.
I'm sure serious runners would know how much cushioning they need, but even then it's a compromise because the stiffness is not adjustable except maybe by adding a heelpad or insole. The whole idea of this is that the sensors measure deflection and adjust the stiffness of the sole so that it's soft as possible without bottoming out. The article is short on details, so I think heel cushioning is the only characteristic that it adjusts. You could theoretically design a shoe that adjusts its geometry to compensate for over or underpronation, but now you're talking about a medical prosthetic device with much more liability.

Bochs is already painfully slow on an Athlon XP. I wouldn't want to imagine running it on a 400Mhz ARM.
