Most people would hardly notice a.25 hike in gas prices.. but consider this math:
Based on 12k miles per year the difference between a 45mpg hybrid and a 15mpg SUV is going to cost about $100/year more with.25 more gas taxes. If the person has a reasonably efficient 30mpg sedan, you're talking about $50/year.. Either way.. it's not a noticeable cost increase.
Raising automotive gas taxes is still the best way to fund DoT budgets. Remember, that weight of vehicle plays a large role in road wear, AND fuel efficency.
Except for the fact that if private companies provided the network, it would only cover profitable areas, ignoring areas where usage is lower.
Then you have to deal with open spectrum managment.. so you let "private companies" put in the network, how many companies do you allow to put up APs? 2 3? all the spectrum is now useless.
Or better! now you have a single monopoly running wireless, stomping on anyone who puts up an AP in their home. Charging whatever they feel they can get away with, which shrinks the profitable areas even more.
Data networks are fast becoming "necessary" for everyone to use.. this is the time for govermental bodies to take over the data network, providing it as a service just like they repair the "necessary" roads, water, and sewars
I have been dealing with issues like these in MN, and the city governemnts are NOT interested in another ricochet.. putting up many many devices all over town, just to go out of business and let the garbage rust.
Here is the solution to the problem:
Let the city run the network, provide the infrastructure, and sell time on the network to the private companies who can compete and provide added value services.. and i'm hoping city people start to figure this out, and take over the in-ground fiber as well.
Why do private companies run around and dig up streets to put fiber in.. that's silly.. the cable should be just part of the base city infrastructure, time on the network is easy to sell.
What I would like is a better transit map searching system.. I'm planing a trip to SFO, and having a nice on-the-fly map drawn of different bus/train routes would be handy.
You're right.. most of what is failing in cars these days are sensors.. MAF, O2, position sensors, etc.
Like the FA says.. it was a failure in the temp sensor that caused the heating to malfunction.
the funny thing is.. parrent post said "heating" to be electronic free.. the heating in most cars comes from a simple coolant heat exchanger from the engine heat.. no need for electrical systems.
The only thing electronic is the fan that blows the air.
While OBD-II is an open standard, you still need all the codes for each vehilce.. and most mechanic shops have idiots who couldn't operate a laptop so they end up having to buy the vehicle dependant diag scanner.
What someone needs to market is a really good palmos/ppc scan code reader.. a bluetooth box you plug into the car and then just stand back and read the codes.
Personaly, I am going to pick up a VAG-COM adapter for my car.. it's mostly standard, but it knows all the VW specific codes.
Other people have mentioned support, and I'll add to the list:
Quality Control.
I've had whole labs of PCs bought from white-box vendors, and whole labs bought from Dell etc.
We had a white-box lab of 700mhz slot-A athlon systems. after 6 months of running, we had just about every CPU fan die within a 3 week span. The machines were somewhat unstable, mostly due to poor ram compatability. When it came time to cycle the lab, we ended up having to dumpster about 1/2 of them because of problems. (the rest were distributed among grad students who still had PPro200 systems)
Because of volume, Dell/etc can simply do a better job of quality testing before releasing a box.
Yep.. I love Ubuntu (go dieman) and Debian for all of my home stuff.. but I have to say.. for all of our servers and workstations, doing just about every task we need from desktop PC's, to HPC clusters, to single machines with 16+ processors, Redhat wins hands down as the mmost stable, easy to make work, and supported by all the stupid commercial software vendors OS we have. With systems like IRIX falling by the way-side, Redhat is my fav for "on the job" stuff.
What I would love to see is a cheaper service, say $15/month including modem rental ($3/month these days) that includes say 512kbps down, and 128kbps up.
This would increase the availability of internet access to a MUCH larger percentage of the lower to middle income bracket households. And remove the "it's not worth N $" excuse people use for sticking to dialup.
You're a little off on the numbers.. but here is some better info.
http://www.dslreports.com/faq/8084
The big reason for the difference between up and down is the fact that the head end can transmit much faster than the modem can upload.
most modems are DOCSIS 1.0 or 1.1
This gives a bandwidth of 30-38mbps down and 5-10mbps up per "node" on the cable companies network. Compare a "node" to an ethernet hub where everyone shares the bandwidth.
You're right. I don't give a rats ass that my next door neighbor runs XP on their computer. That's their choice. I personaly run Linux, at home and at work.
Linux was started becuase _we_ the community wanted it. Then it was realized that Linux could replace windows. Sirens sounded at Microsoft. We became their cometition.. but that's not something Microsoft is used to.. a non-profit community was now competition. Sure, they can slam some linux companies into the ground and feel satisfied they took care of the competition. But there are a dozen companies that will take their work and sprout up in their place. Then there are groups like Debian, who no PR department in their right mind would attack.
Most of this has been over-dramatized by whining assholes on the treocentral forums. The impatients, self importance, and ignorance on treocentral rivals the WORST comments on slashdot. If it wasn't for the jewels of information coming from a select few posters, I wouldn't even visit the site.

I think that people who can't drive a manual transmision, change a flat tire, or even know where to look to put more oil, coolent, etc in their cars are not necesaraly dumb, but LAZY. I think most of the problem with "computer users" is not that they're dumb, but lazy.
I love cars for the ease of analogy with computers. Neither one is an investment. Both can do work and entertainment, but require upkeep and maintence. Both have technical termonology that has has many layers of depth in understanding. Both can save time, and at the same time waste away valuable hours of your life.
If people would get off their lazy asses and learn A LITTLE depth to the tools they use, they would be a lot better off.
btw, when it comes to cars, I can do a break job, replace the susspension, re-wire the electrical, cut out and replace exaust systems, and diagnose some basic engine problems. I consider this to be a fairly reasonable skill level for someone to attain without any kind of special training. I simply read a few books on basic car mechanics, some repair guides, and just looked under the hood of a few cars. I don't claim to be anywhere near the skill level of a pro mechanic, and I don't expect anyone to have pro skills with computers.. but being able to tell the differnece between an O2 sensor and a sparkplug is not hard. Knowing the difference between IE and Firefox isn't hard either.

I guess I didn't know about Apple's Clustered FS.
We have clustered filesystems on all of hour HPC systems. We have GFS on our "small" 80 node linux cluster, 3 GFS+NFS servers to the nodes.
We use GPFS on our Power4/AIX systems, and we have CXFS on our SGI Altix systems.

You're leaving out a lot of stuff necessary to make a cluster:
#1 RAM: $3000 for the G5 cluster node includes 512mb ram. Most places demand atleast 2gb ram per CPU, we require 3GB ram per CPU in all new system purchases. This brings the node price (from apple.com) to $6500 200x $6500 = $1,300,000
#2 Racks and power: Each rack can hold about 32 machines (without getting way to hot/dense) for 200 nodes, this would be about 7 racks. 7x $1200 = $8400
#3 Interconnect: No HPC system is usefull without an interconnect. An 80 node myrinet system was $250,000, so at $3125/node you're looking at: 200x $3000 (estimate) = $600,000
#4 Networking: you need a network switch and cabling to connect all the nodes... gige is a must these days. Let's say we go cheap with HP ProCurve 2848 Layer2 managed for $3300 each we need 7 of those, one for each rack cabinet.. with trunking we can get 4gb back to a central switch. not too bad. Say we add $10/cable for pre-made patch cables, (length averaged) that's about $2250 in cables. 7x $3300 + $2200 = $25,300
#5 Disk: You quoted a bunch of XservRaid's without any kind of apple care.. with IDE raid.. I'm not going without some kind of support on it. Oh wait.. 1 file server is NOT enough to handle 200 nodes of HPC.. and apple doesn't have a clustered filesystem. You're going to have to go with Linux/Intel with RedHat GFS for that one (yes, there are other options, but I know GFS) Say we do 4 XserveRaid's with applecare: 4x $16,000 = $64,000 We also need for dual whatever intel machines: (i'll be nice and include F-C cards in the price) 4x $3000 = $12,000 We also need a F-C switch to link all the nodes: SanBox 8 port $5200 and 8x SFP modules $750 = $11,200 I'll pretend like we don't need GFS software support, but most places would want it. (it's another $20,000 or so, but eh.. we want cheap solution) Disk total comes to: $87,200

Well, that depends on your definition of "Pagan". Which I'm guessing is more along the lines of wiccan.
Back when the gegorian calendar was invented, pagan ment anyone who wasn't christian.
The whole "unlucky 13" superstition is the killer for the 13 month calendar.
It's funny, we still use the "pagan" names for days of the week.

the month is exactly 4 weeks
