With Skype, with other video conferencing, and with projection screens, I no longer have to travel 1000 miles to stay in a hotel with a 1000 rooms, eating meals made for a 1000 people, who otherwise could use the equivalent time to actually pick up an e-book (if that is possible) and learn the material on their own.
In my view, conferences are just paid vacations. On the other hand, taking a course about a product, or a presentation of something worthwhile, such as meeting a future boss is worth it. I would say that conferences are where musical chairs take place, with A quitting his job to go to xyz, and B quitting his job to go to abcd. In the end, you get to know someone and have been lucky to have a handshake,
So, a vacation trip for a family is and should be a discount fare. A trip because of marriage, or funeral should be too. And business fares may be that category too, if the city holding the convention treats all fly-in participants as a group.
As an example of gouging, I consider as over, the era of 60% profit, of gouging the customer so the overprices pay for the next big warehouse store. Margins have to come down to where a store is self sustaining, based on reasonable markups. I hate my Big Box electronic store for that reason. I buy USB cables for $3.00 at a Dollar store, and avoid paying the $29.95 for the heavily marketed name. A $25 profit above the Dollar store price is robbery and with that example, the airlines are trying to do the same thing.
Screw the airlines. I drive 8 hours instead of taking that one hour flight. That flight costs me parking at the airport, renting a car for the day at the destination, and then flying back. Often times, I just rent a car from my home car rental dealer to do the return 8 hour trip. No wear and tear on my own car. And I have comfort, music I like, pit stops when I want, detours to visit a place during the trip and most of the times we are two or three going to a conference. When we are more than one, sitting behind the wheel is shared.
Mandatory reversible sterilization of all children when they turn 12 years of age. Then let them undergo the procedure for free to reverse it after age 21 if they choose to do so.
Dear God, I hope you're not serious! You'd let the government sterilize your child? If this law came in in my country, I'd be on the first to start the revolution.

Could we do to copyright what companies do to avoid paying real estate tax in California? In CA, properties aren't reassessed for tax purposes unless they are sold. So companies don't sell real estate, they sell a shell company that technically owns the property. The property never actually changes ownership, so the taxes remain based on its valuation from 1982 or whatever.
So we just need a free way to set up a corporation. Have your corporation buy an mp3 or a movie. When you're done with it, sell the corporation for $3. Problem solved.
=== Lets extend this rule to all fixed properties. The only problem is that the shell company has to have revenue, file annual income tax statements, and so forth. What if the company's charter lapses?
I buy my house from the Indians who owned the land that the builder purchased. Now, the builder is dead, as I have my house 40 years, and I want to sell it.

3D TV is not yet ready, unless we can really get 3D synchronized sound. What about smellovision. Pass by a pizza vendor and smell the food.
In this case it's probably not bribes (common as that is), but politicians putting their corn-growing state before the country. Corn is not a good source of ethanol but it's great for the economies of states like Iowa and Illinois.
As to causing people to suffer, the pumps are labeled. Put E-15 in your '69 Mustang and you're just stupid.
When you divert feed crops (corn, etc) to mix with gasoline, you actually raise the cost of corn syrup, and corn byproducts to food producers. The result is a very large increase in the price of food. Add to the diversion, the climate change impacts, and you should expect your foodbill to double from prices of 2009. In fact, it is probably already at 180% of the 2009 prices.
The other negative impact is that surplus corn, when there was some, was given to nations or countries to ward off starvation. This surplus and more has dried up.
The subject might look like I'm trying to troll, but... I'm actually referring to TFA. AMD sent the TechReport reviewer a Gigabyte Z77 motherboard with an Intel i7-3770K processor. So it says on the first page of TFA.

I live in Montreal Quebec, Canada. For the past 15 years I've noticed a three day per year delay in the start of winter. When I married in 1968, Winter arrived for mid November, and Left in End April. Last year, winter started (storm with permenant cold) about 20 December and Spring came in March. Today is the 22nd of December, and yes, today, we got our storm and what will be permenant cold until March.
For Canada, it is great. because we have better crops because of the longer growning season, and because we do not get the absurd heat of summer that the USA midwest experienced.
Some say that the US desert in Nevada will gradually increase in diameter. Lets hope that what we see is an anomaly and that the temperature and growing seasons will return to what they were 45 years ago.

For me, the bigger the screen, the more useless it is because the touchpad interface requires larger and larger gestures to get at what's needed.. Remember the windows 2k/xp start menu with its crazy long cascaded menus? No one wants to sort through those. Metro 'start' is like that, only worse because the tiles are huge.
Most of the complaints in the video link are right on.. It's jarring and mystifying at the same time. Basic functionality should never, ever be hidden. That includes configuration utilities.

Just take away the bullets. A gun collector buys guns for what purpose. For the technology. Do not allow automatic weapon type bullets into the hands of gun owners, but do allow the bullets to be available at gun ranges. Count the shells to insure all bullets are accounted for.

There are problems with many of the arguments against the scanners. The medical danger should be a concern to everyone, but evidence suggests that the danger is negligible (though possibly nonzero). The privacy danger is patently obvious and verifiable (though sometimes overstated), but it's just not a concern to many. The cost-benefit argument has the problem that the "benefit" can be very difficult to accurately measure and the government may choose not to disclose data about whether the devices are beneficial. (This is, regardless, the argument I prefer.)
That's not to say there are no problems with arguments for the scanners. At the very least (the very least), it makes sense to use the microwave scanners over the X-ray backscatter. The medical danger is known to be zero, which is even better than the backscatter's best-case of "is probably zero". Even if they're less effective, we don't seem to be relying on either system to be particularly effective.
If the radiation is so infinitesimal to not present a hazard, why won't my dentist not allow herself to go through the scanner, and why does my dentist put this heavy lead shield around me when scanning my jaw for bad teeth?
Too bad they cannot protect eyes and brain from those dental xray machines.
When she takes the xray, I am in a room of my own, with lead lined walls, ceiling and floor. The xray controls (button to initiate the scan) are out of range in another area.
Well, for phone companies (and in the past, DSL) there was a rule saying they have to make their lines available to other companies.. which is why, say, in the days of dial up you could buy your phone service from one company and then dial in to any ISP you liked. DSL used to work the same way, you bought your line and then could use any ISP you wanted. Cable modems never had this, and when DSL providers complained it was unfair, rather then extending the policy to cable they dropped it for DSL, resulting in pretty much the eradication of competition over night.
Putting that bit of regulation back in place would probably spawn all sorts of consumer choice without having to deal with the barrier to entry that is laying physical lines.
=== That choice still is possible in Canada. I had lines with Bell Canada, but two other ISPs that had no lines, were my providers at half the rate that Bell charged. Two years ago, we had unlimited downloads, then they forced a new contract to 100gigs, now it is 60 gigs. Bell and in Quebec, Videotron, know how to gouge.
btrfs is a step in the right direction, but even now, Linux does not have production-level deduplication (which even Windows has, for crying out loud), encryption, snapshots, or something even close to supplanting LVM2.
I just got out of a meeting at my job because we are replacing some old large servers... and because Linux has no stable filesystem with enterprise features, looks like things are either going to Windows, or perhaps Solaris x86 (which is expensive.)
This doesn't mean to suck Sun's teat for ZFS access... but at least try to come close to what even NTFS or even ReFS offers...
=== What is the big complaint about btfrs. Is it the egg that it should be hatched at perfection? With the new kernel out this or next week, btfrs will gain major performance improvements. btfrs will surely be a desktop file system, until all security issues are resolved. The DOS attack is done by someone able to use the keyboard on your desktop or server. In my opinion the DOS is really an academic study. ZFS and even EXT4 will have some form of weakness. And NTFS too, if you are a windows server user.
I've been using btfrs with Fedora 18 beta since November. I can pull the plug, and it recovers nicely. I have not tested all the wonderful features that come with it, but I will. ZFS looks interesting too. Am I stuck on one or the other? Benchmarks measuring speed recommend EXT4 as the best choice. I leave the evaluations and recommendations to you, the reader of my reply.
Perhaps the "pump" part of heat pump completely eluded you, since they do not defy the first law of thermodynamics as you seem to be implying.
Heat pumps work by having a sink source off of which they are pumping the heat from or away from. Most of the ones I know happen to be geothermal, which work because the sink which they are pumping from maintains a constant temperature year long underground. So, during the summer, the heat they can extract from that source would be cooler than the air above ground, but during the winter be hotter. They do this by extracting the heat from the source sink, rather than producing it themselves.
So in that respect, they work much like the fan does within your computer, since the air inside the case is much hotter when running than the air outside of the case. The fan can then displace that heat generated inside rather efficiently by just pushing the hotter air inside the case out, while bringing the cooler air from the room outside in without having to require an equal amount of energy to then power those fans as the equipment running inside of it, thus, like the grandparent, requiring less electric energy to power those fans than what the computer itself uses. If this were not so, then it'd make a lot more sense to completely seal computer cases, as the cooling benefit from the fans wouldn't make up for the amount of dust which they bring into the case during operation.
So the next time you're tempted to call bullshit on a well known physics principle, make sure you double check that you're not making some stupid mistake. Or else you'll end up looking rather foolish again when someone else points out how you don't know what you're talking about.
=== We had a Ground source HP. Three wells of 100foot depth. It worked well for two years. but the ground shifted, the pipes got pinched, and the result was "no heat". The cost to re-bore the wells was too much. So we switched to an air exchange based heat pump. In summer, the cooling was redirected to water exchange coils with the swimming pool, which received the heated water while we a/c'd the house.
For the rest of your article, it makes sense to me
Get your head out of your ass. Most electric heating is done with heat pumps. A heat pump pumps more heat into your house than the electric energy it consumes (that's why it's called that way). Heating by burning something is also more efficient than dissipating electric energy because you're cutting out conversion (see Carnot efficiency) and transportation losses.
And in the summer, if the AC is on, inefficient appliances make you lose double: once by consuming more electricity than they should, and a second time because the AC needs to consume energy to pump the heat out of your house.
Where I lived, the temp drops below 0F at which the heatpump is running at near zero percent efficiency. Actually, at 10F, I disable the heat pump and rely on electric element heating.
Now I live in an older home with radiators and hot water in circulation. The hot water is supplied by two electric boilers. The circulating water temperature is inversely proportional to the outdoor temperature. Above freezing, the water is luke warm. At 10F, the water is around 140F. and colder (5F) it sits at a max of 165F. For safety, that is also the upper limit.
> Ubuntu needs money to cover the cost of all it's offices, staff, and some reserve for growth and support.
yeah, maybe they should have thought to that before killing the market for desktop distribution by shipping their own for free ( lycoris, mandrakesoft, suse, all have dropped their desktop ( and most are dead by now ) after Shuttleworth decided to give for free something paid with his wealth ). It has a been a few years since Canonical execs promise us "we will be profitable soon", but this is not gonna happen, and things will only become sour now, since they start more and more to push benefits rather than reducing their spendings ( like a office in the center of London, one of the most expensive towns in Europa, paying luxury hotel for UDS for the staff, etc )
That's not the point. Senseless regulations just for the sake of their being regulations is dumb. Pilots can use them, passengers can't? - and there is no valid reason why not. If they want to say, "No it won't bring the plane down, but we need everyone's attention to listen to this important safety announcement about belt buckles" fine - just be honest about it. Don't treat me like an idiot.
Just don't feed me a line of bullshit about it might interfere with the electronics of the aircraft. The people that buy in to that irritate me almost as much as the control freaks pushing the message. Have rules that make sense and I'm cool. Foist rules that are bullshit and that treat me like an idiot and we have an issue.
So chill out, cupcake. Don't be all "stop your whining" and sarcasm. Whether it is someones big or small problem, it is "their problem" and it shouldn't be A problem if it was based on honesty.
Please do not allow it. My wife can talk for hours after a full charge of her phone. You really don't want to sit next to someone who wont shut up for the whole flight. (Wife is one of 13 siblings)

This doesn't mean to suck Sun's teat for ZFS access... but at least try to come close to what even NTFS or even ReFS offers...

What is the big complaint about btfrs. Is it the egg that it should be hatched at perfection? With the new kernel out this or next week, btfrs will gain major performance improvements. btfrs will surely be a desktop file system, until all security issues are resolved. The DOS attack is done by someone able to use the keyboard on your desktop or server. In my opinion the DOS is really an academic study. ZFS and even EXT4 will have some form of weakness. And NTFS too, if you are a windows server user.
I've been using btfrs with Fedora 18 beta since November. I can pull the plug, and it recovers nicely. I have not tested all the wonderful features that come with it, but I will.
ZFS looks interesting too. Am I stuck on one or the other? Benchmarks measuring speed recommend EXT4 as the best choice. I leave the evaluations and recommendations to you, the reader of my reply.
Perhaps the "pump" part of heat pump completely eluded you, since they do not defy the first law of thermodynamics as you seem to be implying.
Heat pumps work by having a sink source off of which they are pumping the heat from or away from. Most of the ones I know happen to be geothermal, which work because the sink which they are pumping from maintains a constant temperature year long underground. So, during the summer, the heat they can extract from that source would be cooler than the air above ground, but during the winter be hotter. They do this by extracting the heat from the source sink, rather than producing it themselves.
So in that respect, they work much like the fan does within your computer, since the air inside the case is much hotter when running than the air outside of the case. The fan can then displace that heat generated inside rather efficiently by just pushing the hotter air inside the case out, while bringing the cooler air from the room outside in without having to require an equal amount of energy to then power those fans as the equipment running inside of it, thus, like the grandparent, requiring less electric energy to power those fans than what the computer itself uses. If this were not so, then it'd make a lot more sense to completely seal computer cases, as the cooling benefit from the fans wouldn't make up for the amount of dust which they bring into the case during operation.
So the next time you're tempted to call bullshit on a well known physics principle, make sure you double check that you're not making some stupid mistake. Or else you'll end up looking rather foolish again when someone else points out how you don't know what you're talking about.
=== We had a Ground source HP. Three wells of 100foot depth. It worked well for two years. but the ground shifted, the pipes got pinched, and the result was "no heat". The cost to re-bore the wells was too much. So we switched to an air exchange based heat pump. In summer, the cooling was redirected to water exchange coils with the swimming pool, which received the heated water while we a/c'd the house.
For the rest of your article, it makes sense to me
Get your head out of your ass. Most electric heating is done with heat pumps. A heat pump pumps more heat into your house than the electric energy it consumes (that's why it's called that way). Heating by burning something is also more efficient than dissipating electric energy because you're cutting out conversion (see Carnot efficiency) and transportation losses.
And in the summer, if the AC is on, inefficient appliances make you lose double: once by consuming more electricity than they should, and a second time because the AC needs to consume energy to pump the heat out of your house.
Where I lived, the temp drops below 0F at which the heatpump is running at near zero percent efficiency. Actually, at 10F, I disable the heat pump and rely on electric element heating.
Now I live in an older home with radiators and hot water in circulation. The hot water is supplied by two electric boilers. The circulating water temperature is inversely proportional to the outdoor temperature. Above freezing, the water is luke warm. At 10F, the water is around 140F. and colder (5F) it sits at a max of 165F. For safety, that is also the upper limit.
So, will this address the commercials compressing their sound so that it SEEMS to sound louder...?

Because of reduced loudness over 4 minutes, the 4 minute commercial will be extended to 5 minutes at current loudness.
Since many pay for incoming text, there should be a class action suite against ccAdvertising asking for compensation and for harassment..
I atill run Linux on pentiums as 486s. Will I have to revert to XP?
> Ubuntu needs money to cover the cost of all it's offices, staff, and some reserve for growth and support.
yeah, maybe they should have thought to that before killing the market for desktop distribution by shipping their own for free ( lycoris, mandrakesoft, suse, all have dropped their desktop ( and most are dead by now ) after Shuttleworth decided to give for free something paid with his wealth ). It has a been a few years since Canonical execs promise us "we will be profitable soon", but this is not gonna happen, and things will only become sour now, since they start more and more to push benefits rather than reducing their spendings ( like a office in the center of London, one of the most expensive towns in Europa, paying luxury hotel for UDS for the staff, etc )
So yeah, cry me a river..
Gee, reminds me of Google.
That's not the point. Senseless regulations just for the sake of their being regulations is dumb. Pilots can use them, passengers can't? - and there is no valid reason why not. If they want to say, "No it won't bring the plane down, but we need everyone's attention to listen to this important safety announcement about belt buckles" fine - just be honest about it. Don't treat me like an idiot.
Just don't feed me a line of bullshit about it might interfere with the electronics of the aircraft. The people that buy in to that irritate me almost as much as the control freaks pushing the message. Have rules that make sense and I'm cool. Foist rules that are bullshit and that treat me like an idiot and we have an issue.
So chill out, cupcake. Don't be all "stop your whining" and sarcasm. Whether it is someones big or small problem, it is "their problem" and it shouldn't be A problem if it was based on honesty.
Please do not allow it. My wife can talk for hours after a full charge of her phone. You really don't want to sit next to someone who wont shut up for the whole flight. (Wife is one of 13 siblings)
