It's not a carrier like a modem carrier, though, and I suppose you could argue that it's not really a carrier since ethernet (100baseTX) is a baseband signal. (Which on another point of pedantry is to say that people who think ethernet is broadband are wrong, ethernet is not broadband, it's baseband. Broadband doesn't mean "fast", it means a broadband signal. DSL is a broadband signal, even when it's only 256 kbit/sec).
The 'no carrier' status is generally given when the ethernet card doesn't see the regular NLP (for 10baseT, NLP = Normal Link Pulse, a regular pulse) , or FLP (for 100baseTX, FLP = Fast link pulse, actually, a pulse train encoding IIRC 16 bits of information about whether the connection is full duplex, half duplex etc). The presence of an NLP or an FLP allows your ethernet card to autonegotiate connection speeds and settings. The NLP and FLP are much different to the actual data signal - the NLP is just a regular pulse when the line is idle, and the FLP is a short pulse train. To contrast with the actual data, 10baseT is Manchester encoded (with a fundamental frequency of 20MHz), and 100baseTX uses a three level signal called MLT-3, with a maximum fundamental frequency of 31.25 MHz. (Only 11.25 MHz higher than 10 meg ethernet! MLT3 is a 'non return to zero' coding, and to avoid long trains of zeros which would result in no transitions at all, and a loss of clock recovery, 100 meg ethernet is actually 125 Mbit/s on the wire - an extra bit is added by encoding the data as a 4B5B code).
No, UPS and FedEx et al. could not eat the USPS's lunch. No one is interested in the universal service because it doesn't make money. Delivering first class mail from Florida to Seattle for pennies does not make money. Even more so, delivering mail from Mexican Hat, Utah, to Matagorda, Texas is even more of a loss maker.
The private firms would only be interested in cherry picking the bulk mail and major city services, leaving all the unprofitable bits of universal service to the USPS. This is why the USPS has a monopoly on the universal service, because others are only interested in cherry picking the best bits of it.
There are probably at least 6 months of the year (at least spring and autumn) where the temperatures are amenable, though. I used to live in Texas, and temperatures for at least 6 months of the year were amenable for a bike commute.
I don't cycle to work every day - I do it on the days the weather is amenable. This is still at least half the days of the year - and it saves me considerable money (petrol is almost US$10/gal on the small island where I live), as well as keeping me fit. Showering time makes no odds - I spend half an hour showering/getting dressed whether I do it at home and drive, or whether I ride and do it at work.
In any case if work doesn't have a shower it does at least have basins etc. and you can wash yourself adequately. I have worked at such places and it is possible. One of those places was coastal Texas - hot as hell and humid as hell in the summer. It just ain't rocket science.
Fuel is a lot more expensive here - your fuel is obscenely cheap at only $4/usg. My last fill up (tonight) was 124p/litre for unleaded, or 471p for 1 US gallon, or roughly $10 per US gallon.
I do live on a small island though (30 mi long and about 12 mi wide at the widest point), and the fuel has to take a 60 mile trip over the sea to get here in the first place, and fuel taxes are extremely high here.
Your numbers neglect the basic fact that your body is a lot more efficient if you're fit vs being unfit. So while I may burn more energy going to and from work, I burn less when I'm sitting in front of the computer. My resting heart rate is only 45 bpm when I'm in shape from riding to work. I also don't need a gym membership (saving money there) to keep a basic healthy level of physical activity. So the incremental cost of cycling really is only one banana per day more than not doing any exercise at all.
The howstuffworks analysis doesn't say what kind of bike either - the difference between riding what most people have as a bike (a mountain bike of some sort) and my proper road bike is dramatic - I can probably go twice as fast on the same energy expenditure on my hard 120 psi tyres versus their squishy, knobbly 30 psi tyres.
We did? You could change X video resolution with a simple set of keystrokes... in 1993. While it wasn't a particularly user friendly way of changing resolution it could be done and it didn't require a desktop restart.
You can't hide something away with a patent - patenting actually does the opposite - it makes it public. You can only lock it away for a pretty limited time period too.
With fuel prices here, round trip to work by car costs £5 a day (approx US$10). Round trip to work by bicycle costs one additional banana (about £0.20) as far as I can tell. My commute is a reasonably hilly 25 mile round trip.
Paradoxically, I do a lot more 'comfort eating' in the evening if I've driven to work than if I've biked, something I don't really understand, so in reality, the one extra banana during the day for a bike day, is easily replaced by 'comfort eating' in the evening if I've driven - although if I had more discipline I could probably not just 'comfort eat', because I certainly don't need the extra energy on those day.
Those stats probably include cyclists who don't have lights and reflectors, and therefore is distorted. Anecdotally, I have found riding at night to be far safer than in the day - car drivers give me MUCH more room than they do in the daytime. Then again, I have a headlight that's bright enough that I can ride at 30 mph with confidence on unlit roads (much of my ride lacks streetlighting), retroreflective strips on my backpack, a rear light with six Luxeon power illuminators, a further retroreflective and flashing ankle band so I make damned sure I can be seen.
*All* of the close calls I've had on the bike have been during daylight hours, *none* at night.
I do a lot of sysadmin work, yet I've *implemented* a DNS client (in assembly language, no less, for an 8 bit system).
Sometimes, a sysadmin job is a little more than poking the odd server - a sysadmin job can involve a lot of automation work which requires software development. It all depends on the particular environment.
Hopefully we can do the same with the Sinclair Spectrum soon - I've almost completed the prototype ethernet card for the Spectrum. The prototype is working - I've had it connect to IRC, but there are some things to finish on the library and the board's CPLD.
The trouble is antivirus can be worse than useless. It has proved so at work.
So far, the AV solution at work (Symantec, corporately rolled out) has not detected any viruses. However, it has false alarmed and quarantined part of the Windows Server Resource Kit (fortunately, a part we were not using) - on two occasions. Not at our company, but in China, IIRC it was Symantec that also quarantined a system file in the Chinese version of Windows, causing serious problems for thousands of users.
Meanwhile it chews up CPU time.
The only time it WOULD have been useful was before we had Active Directory and centralized updates. Before that time, someone took their laptop home, and connected it directly to the internet via their ISP and got infected via a bug in Windows XP. Symantec failed to detect the malware that was sent - indeed, it took two weeks before the signatures for that particular piece of malware showed up. It happened about a month later in another part of the company.
To my knowledge, Symantec has never actually detected and neutralised a threat - rather, it's damaged the Windows Server resource kit and failed to detect the only infection we've ever had. We would be better off with out it.
Ah yes, just like the RIP Act in the UK was only supposed to be used for cases of serious organized crime - but ended up being used to spy on parents to make sure they weren't trying to get their child into the wrong school, or to spy on householders to make sure they were putting the rubbish in the correct bin etc.
I thought all the electromechanical (Strowger) exchanges disappeared from the Western world by the early 1990s... where is this exchange? It's a veritable museum piece. Try to get a visit while it is still operational.
To be pendantic, broadband has nothing to do with speed. ADSL is broadband regardless of the speed, because it uses broadband signalling. By contrast, 100 meg ethernet is *not* broadband, because it does not use broadband signalling - the hint is in the name (100baseTX) - the 'base' means baseband.
My colleague is an ex telecoms engineer. The telco went through a bout of using cu clad aluminium wiring, but over time the contact wears out in any kind of clamping system (say, punchdowns commonly used in Cat5 installations, screwdown terminals, IDC terminals such as RJ45 jacks) - and it would start failing.
Used for house wiring, the increasingly bad contact over time in typical screw-down terminals found in domestic wiring installations would cause resistance heating and possibly fire. There's good reasons why houses don't have Al wiring. The eastern bloc tried it, I have a friend who lives in the Czech republic and Al house wiring is very unreliable.
It's not unusual for people in their mid 30s to be gamers instead of TV watchers. Don't forget, those in their mid 30s were the *vanguard* of gamers - they grew up with the ZX Spectrum, Commodore 64, BBC Micro etc. - the Spectrum alone had over 8,000 titles available by the late 80s.
Just for grins, I selected 'Show all available applications' in Ubuntu's Add/Remove Applications and typed the word 'podcast'. Lo and behold, it listed a number of applications that can play podcasts, and was nice enough to show me that I already had an application that could play a podcast.

An interesting observation. This happened in Spain, and was written about on Bebo. In Spanish, "bebo" means I drink :-)

Why is $$ not a good reason?

It is possible to wear different clothes on the bike, and carry a change of clothes. My mother taught me how to fold shirts.

It depends on the sysadmin position.

Aluminium is awful for cat5e wiring.

I did a degree in Systems Analysis (an IT course) and our final year undergraduate dissertation was subject to a viva. There was *no* cheating.
Then again it was 12 or so years ago so the class numbers may have been smaller then (we had 80 start on our degree course, and about 40 finish).
