Why not build a one of the open source bios kernels so that it looks like the mach_kernel and have it then boot something else like Windows, Lilo or Grub?
A low voltage system needs to be 6V (or 12V) so that low voltage light bulbs work as well as things that need to provide their own 5V regulation. USB is short distance and in a modern large house you won't be able to provide 5V at one end without it being too low at the other or being way over for things that didn't do their own regulation. 12V (13.4) make sense since its is the most common power source in the world.
The brand new houses out in the outer melbourne suburbs are poorly insulated.
I live in Fitzroy and there are very few insulated houses here. There is no insulation in the walls at all since they are solid brick or rarely blue stone. The stuff in the roof already exceeds victorian standards and I intend to at least triple it soon. You can't buy double glazed glass planes for the old window at all (and it would be illegal to install it if you could find it).
Most of the old houses had wood or coal stoves and early building requirements required vents in every room. Since everyone is used to having them, they seem to think there won't be any fresh air if they are closed. Sealing up the the ones and putting in cheap weather stripping on the doors and some windows dropped the heating bill in half on a house with hydronic heating.
I have a spare room that I tend to rent out to visitors. I find it interesting that Europeans will routinely turn on the oven or stove when its above 30 Degrees (C) even though they consider it extremely hot. There is a reason there is a nice bbq out in the back.
If anyone cares, it was over 45 degrees (113) here over the weekend with the official high of 43 out at the airport where they have lots of nice grass around to help keep it cool.
If the the imac is like my mini-mac, then keeping it in sleep mode for a few hours saves more power than the extra power required for a full boot. I don't know the cutoff time but I expect if your going to leave it all weekend, then off is the best option but if you check it several times a day and its only idle 8 or so hours while you sleep, then keep it in sleep mode.
I've been looking for ways to replace as much of the "on all the time" junk with smaller more efficient systems. While it would be nice to keep the email server local, moving it to the cohosted server thats on all the time anyway makes lots of sense.
You can also use wake-on-lan on some systems to kick start them when they need to wake up. The real trick with that is keeping all the garbage traffic away from them while having something that can watch the lan for traffic and kickstart the bigger box.
All the devices that listen for a signal run at 5 volts or less. In your case, one more efficient plug pack should be more efficient than several of varying efficiency.
What needs to happen is someone needs to come up with a new power outlet standard that provides both A/C and a 6V DC signal. This year there are only a few standards left (120V/60 Hz or 230V/50Hz) and the number of plugs is decreasing but the British and Aussie (and Kiwi's) still are using different outlets than Europe. The US style of power is more efficient on most smaller stuff but is worse on the higher power situations such as big motors and heaters.
Thats why I ask my congresscriters to extended the copyright far longer than what Disney is asking for. At some point they will go "if 20 years is good, then 40 should be better" at someone point they give a bunch of people to take the major media giants tot he cleaners. Sometimes you have to learn that you can't fight government corruption directly and you must do it the round about way.
Most of the wireless network in the US has more capacity per customer than the POTS network does. The difference is in the wide variety between oversubscription rates on different cells. There is also the issue that many telcos had to upgrade exchange connectivity because of the increase of modem lines but now most of them are going away and the old capacity is still there.
EFI is a boot loader. Bios is a program. Why not get one of the free Bios systems and reconfigure it so EFI boots to it and then it can boot windows. Hasn't someone already done this sort of thing for grub?
Why is this so hard? Problem: Disks Die Problem 2: They aren't free Problem 3: I can't lose any data at all ever even the stuff from the last 24 hrs. Oh wait, home users and 99% of business don't have problem 3 even if they think they do.
So you get your self a nice cheap low power box with a big disk(s). Since its on 24x7 maybe even consider some some of the 2.5 inch disks or if you need speed (which you don't) get the 10k 2.5inch disks. So you get a few external cases with firewire and/or UBS2. Set up cron job based on the speed of the machine and how much data your willing to sacrifice to rsync the external disk to the internal one. Then every so often you can pull the external disk off and swap it with one you keep at the office. This protects you from any single disk failure and some cases of two disk failure (i.e. lighting strike at the wrong time). You also get an offsite backup and you have a backup of a few days or weeks ago. Another thing to keep in mind is keep the formatting simple. It means less issues when things break and things will break.
There are already laws that say offering drugs to kids will result in jail time. Why hasn't even a single hot shot want-to-be prosecutor ever apply that to spam and thrown a few of these guy in jail for the next 20 to life? I thought these guys all wanted to save the children.
GPS isn't good enough by itself to even tell you what lane your in. A sub meter differential system is going to cost a fortune and require some larger antennas than what is currently used for mapping systems.
100 yards isn't enough to process the data and stop many vehicles at highway speeds. How do you deal with things that aren't transmitting their position like pedestrians and deer? If you solve that problem, other cars is easy.
The speed limit in most places in the world is more of a recommended speed than a maximum but thats an easy problem to solve.
Are you talking about yokes vs sticks? The yoke replaced the stick because it made it easier to run the cables. The modern stick is based around having fly by plumbing or fly by wire. The rudder pedals haven't changed since they were introduced and modern jets still use power controls like most planes for the last half century.
I've been in a car that could drive its self in along highway in Virginia. The car had radar, sonar to keep it from hitting things and it used differential GPS and fiber optic ring gyros to keep it where it needed to be. The car only knew about a few roads and they have all been driven several times. It couldn't deal with things like stop lights. The INS system alone cost somewhere in the order of $300,000.
There is no other way than to keep spares on hand.
Someone will claim you can't keep a backup of a big database server or other huge machine and the solution to that is redesign the problem so it uses several smaller and cheaper servers.
Another solution is run your disaster recovery site live.
Do you think the Intel marketing department care about what happened a very long time ago? They are going to put a some huge pressure on Apple to kill the Power name and it doesn't mean anything anymore.
I've got an old 68k based powerbook here in my pile of junk but I guess we will find out soon enough but my guess is the Power name is going away.
In the past the different lines were to give different groups options. They could dump the powerbook line by bringing the ibook line above it. I also think that Intel, IBM and Motorola will have things to say about a Power labeled intel machine which means it might just best best for Apple to drop the power label.
When it comes to a wide product range, its more of a liability than a benefit in the modern world that wants their new machine Today. If they can reduce their laptop range to 4 units in total over a wider performance spectrum while narrowing the price point, more people will consider their products.
There will NEVER be an Intel based Powerbook. PowerPC is IBM's Trademark and an Intel based PowerBook would result in a cease and desist letter from IBM.
All Apple needs for an Intel based machine for the school market is the student version of Office and iTunes.
The other thing is they can't release a high end Intel laptop because its simply not fast enough to outdo the quad G5 benchmarks so if they released a high end Intel machine now, their Intel shift would look like a very bad idea and their stock price would tumble.
I think the TV's they are talking about are the type that don't have any video inputs. There are more TV's in the US than people so 70 million of them would be a significant subset and even modern TV's don't come with digital tuners so this 70 million must be something very old. To make them work, it will require a set top box just like every one else, an modulator, maybe a 50 to 70 ohm adapter and a antenna that work at the right frequency range for digital.
Distilled water is reactive. Because it has not in it and water is a very good solvent, anything that that you normally find dissolved in water tend to try to get its self dissolved in the distilled water. I'm not sure if the same is true for de-ionized distilled water or not.
I've opened several ibooks that have been the subject of spills. So far I've had good luck and only had two that didn't fully work after their accidents. The 1st had water spilled on the table it was on and it sucked up the water into the main board and that killed it dead. The other had sprite spilled on its keyboard and got in too many places and its keyboard / track pad don't work anymore. Two others that had beer and red wine are completely functional.
I don't think the ibooks are very well designed inside. Its a portable computer, its going to get stuff spilled on the keyboard and a bit of consideration from the engineer who designs the RF shielding would mean spills should be diverted. Other laptop companies do this so why not Apple? The thing about the old powerbook 165C sucking water off the table into its insides was just wrong but it was a old machine then so maybe the new ones won't do that.
From a corporate point of view, I don't like the fact that the thing must be fully disassembled to get the hard drive out. The company policy on warranty repairs is very clear that the hard drive doesn't ever go back without being wiped 1st. If the machine is in bad enough shape that it won't go into firewire drive mode, then the entire machine is a write-off. Its tough to get the boss to approve a purchase order for an iBook once they had to write off one.
It seems that everyone has problems with that cool light up AC adapter plug/socket as well. Maybe its time to come up with a new design for that.
Driving in Melbourne is more stressful than any place I've ever driven (includin g Cairo). The road accident stats for this year are worse than last year even t hough there are a significant number of safer cars on the road. Road traffic is
down on last year on many of the major roads. Most of the major roads have exc eeded their capacity and now trips take 3 to 4 times a longer (according to The Age). The minor accidents stats have gone way up and the number that don't even
get reported are increasing as well. Since Victoria has proven that people can be forced to use the speed limit signs
as a "maximum permitted" vs the "drive about this speed", maybe its time to put
a 105 speed limit on the passing lane and see if that won't help the pathetic t raffic flow while encouraging proper passing (i.e. speed up when you pass so you
don't end up in others blind spots and your blind spots are dynamic).

The real reason is to convince the boss that buying the new mac isn't a huge mistake "because it will run windows anyway".
At least with the US keyboards, the mac ones work fine with everything I've plugged it into and that includes windows and linux and sun servers.
There is a rumor that Apple as seen the light with the mouse button issue.
Why is this so hard?
Problem: Disks Die
Problem 2: They aren't free

It doesn't need a straw... it appears that the gaps in the plastic just happen to be the right size to get a nice capillary flow going on.
