That is wrong. The Windows MBR will boot whichever primary partition is marked active. Don't confuse the MBR with the boot sector of a partition.
NTLDR is installed in a windows partition. Grub or LILO can be installed in the linux partition. If you mark the linux partition as the active partition, the Windows MBR will never get to NTLDR.
Then you can use fdisk to select which partition to boot. Or you can tweak boot.ini and grub's menu.lst so it doesn't matter which one gets booted, you can load the other.
I've got a handful of machines configured this way, some since 300mhz was a fast system, and it has been working fine up thru Vista on my development laptop (four primary partitions, one XP, one ubuntu, one that has been Vista but is currently XP, and one that is usually data but has been various Debian derived distros, e.g. knoppix and DSL). Neither of the windows knew the other existed, but now both of their boot.ini's have been modified to know about the other windows and about the other two linux installs. Many times XP and various versions of Vista have been installed and never once have any caused problems with the XP install or with the linux installs on that machine. Worst recovery needed has been to use fdisk (dos or linux) or the local storage manager to switch the active partition.
Windows MBR is totally generic, and as long as you leave it in the MBR by putting your linux loader elsewhere, you will be fine.
Linux DOES have to take over the MBR (with either GRUB or LILO),...
No, it does not, and dual-booting life will be much better for you if you get that mistake out of your head.
Put grub (or LILO) into/dev/hda2 (or whatever primary partition you set aside for/boot). Allow windows to have the MBR and/dev/hda1 (or whatever primary partition you set aside for C:\). Now when windows takes over, you just need to use fdisk to set the bootable partition back to/dev/hda2 and linux will be back in charge.
You can (of course) configure grub or LILO to boot/dev/hda1 so you can start windows. And if you are somewhat comfortable with boot.ini, you can configure NTLDR to boot/dev/hda2 so you can start grub/LILO. Set the defaults and timeouts appropriately and your system will just alternate back and forth between the two bootloaders until you make a choice.
A Gentoo article talks a bit about the NTLDR issues, and installing grub into a partition instead of the MBR.
linux was comparing the files to what it had in its disk cache, not to what was in the disk.
Last I checked the source, linux did not attempt to preserve disk cache across filesystem unmount. Currently observed behaviour indicates this has not changed.
In other words, copy the files, unmount the source and destination, mount the source and destination, compare the original and the copy.
It still is not as sure as copy, power off, power on, compare, but it is a lot easier to script!
I mean really... that was and remains incredibly obvious.
The only reason not to have it is if you did not have hardware mpeg (or equivalent) encode/decode. Without hardware mpeg it takes a bunch of cpu and the low-end processors in the first-gen tivo and replaytv wouldn't have been able to do both simultaneously. But with dedicated hardware, no problem.
...one benefit that you may be overlooking: nobody is subjected to the violence of poverty.
Violence of poverty??? Poverty is in no way "violence" and attempts to equate the two demean and diminish those who have suffered as victims of violence.
I learned years ago that somebody who says "I know about mouses, that's not the one I wanted" is a pain in the rear.
Definitely. Anyone that isn't smart enough to play the cards dealt instead of crying "I want... I want..." like a 2yr old is too painful to deal with.
I mean really, if you don't like a mouse, how hard is it to say, "Using that one is too painful, I think [some other one] would not hurt my [wrist / elbow / hand] as bad." Play the ergo card!
Are you suggesting that in the worst case we just kill ourselves off
Why do you believe we have anything to do with it or could do anything about it?
Those cycles were happening long before humans started using fossil fuel. Occam's Razor would suggest that even a complete cessation of fossil fuel usage would not prevent those cycles in the future.
Once we start thinking rationally about this, our fossil fuel usage is just as likely to have postponed an ice age as it is to have accelerated the warming trend. Any significant reduction in fossil CO2 emissions is no more likely to have positive than negative effects.
Why would you totally mess up the now, on the off chance that you might improve the future?
I much prefer the strategically-placed CDs (data side out) pinned to my cube wall and aimed the appropriate direction

Statement:I don't know what kind of dream world you live in, but in the U.S.A. there is no real difference in process, leverage or power between appropriations and other legislative bills.
Response:This is my last attempt at reasoning with you, unless you're willing to admit to being incorrect in that statement.
So if I do admit to being incorrect, you will continue in your attempts to reason with me? Strange...
I do not know if you are trying to be pedantic re. budget vs non-budget expenditures or not, but I am aware and correct re. appropriations bills.
You appear to be confusing "bills" (which include appropriations bills and reconciliation bills and all other legislative bills) with the "Budget Resolution" which follows the presidential Budget Request.
legislative acts can drastically change expenditures thru appropriations and reconciliation bills
Details
The president's Budget Request is not a bill and does not set any final numbers. It is merely a request or a proposal. (With me so far?)
The House and Senate joint Budget Resolution is also not a bill. The Budget Resolution is NOT signed (or vetoed) by the President! The legislative branch DOES IT ALONE. The Budget Resolution does set numbers. (Do we agree on that?)
The numbers in the Budget Resolution, however, are valid only to the extent that both legislative bodies AND the president continue to enforce that resolution during the legislative process. As evidenced by the historical record, legislative acts can drastically change expenditures thru appropriations and reconciliation bills. To understand how, read your link starting with "How Are the Terms of the Budget Resolution Enforced?"
And that my friend, is how the U.S.A. federal government spends $billions per day.

P.S. The executive branch often proposes legislation. Anyone can propose legislation. The executive branch tends to get more attention than would most people I know. I do not know who originally proposed the DMCA, but I do know who made the final decision and signed it into law.
appropriations vs. laws... if you were being genuinely honest, I think you'd have to admit there's a big difference between those types of legislation and the power the executive branch has to shape them.
Your repeated references to "being honest" are poor rhetorical technique.
I don't know what kind of dream world you live in, but in the U.S.A. there is no real difference in process, leverage or power between appropriations and other legislative bills -- the legislature passes or not, executive approves or rejects. Executive can and does propose, ask, beg, threaten and/or cajole the same for either. And with no line-item veto (which if IIRC was blocked before the DMCA) the executive has to be willing play mud-lot hardball, courage seldom seen, even in a lame duck presidency with or without legislative control.
CommentFunnily enough, like the DMCA, the NET Act was also signed into law by the Clinton Administration. I only point that out to illustrate that selling out your rights to further rapacious corporate profits is not, and never has been, exclusively a Republican trait.
ReplyWhile I agree with you, it's interesting that you point to the "Clinton Administration" when it was congress that wrote the law... a congress controlled by what party now ?
Congress may have written the law, but which branch of gov't is required to approve and enforce the law? Hint 1, it is not congress. Hint 2, which executive in the federal government has veto power?
So... control of the legislative branch is irrelevant. Either the chief executive was responsible for what he signed, or not. Either Clinton was responsible for the DMCA (since he signed it into law) and Reagan was responsible for 1981-1988 deficit spending (since he signed the appropriations) or neither of them were responsible for what they signed.
Pick your poison.

P.S. Signing a bad law vs. signing a bad appropriation... I know which I'd rather live with...
I'm puzzled that VLC doesn't do is provide a hotkey for skipping DVD chapters forwards and backwards. I went looking and found this changeset...
Are you sure it doesn't?
I haven't checked 8.4 final, but sources as of late september had definitions for chapter-next, chapter-prev (and title, and all the others mentioned in that patch description). Try ctrl-u and ctrl-d (default in libvlc.h for Darwin and others).
The [Mentor Graphics EDA] tools are buggy enough in Windows. I can't imagine running them in WINE.
This app, that app... rather than wine, how about the newly free vmplayer (in beta right now)?
The biggest problem is hardware support. I develop hardware support kernel drivers for Windows, so my underlying OS needs to be Windows in many cases. However, for a few days now I've been running Ubuntu (Breezy, upgraded from the provided Hoary image) in a VMWare player session. Works great.
So is there any reason why a migration cannot begin this way? I think not. Start by running Ubuntu in vmplayer. Figure out what works well and what doesn't. The next step would be to reverse the situation and run Ubuntu native, and Windows in vmplayer underneath for the last app(s) that only run under Windows. It sure is nice and easy to distribute a vmplayer image with Windows and the required app(s) already installed (see sysprep). Makes it trivial to "reimage" when problems arise (and all without using 'ghost').
Most apps are going to be just fine in a vmplayer session. The more people run them that way, the more requests Mentor Graphics et al will get for 'native' versions. The more requests, the more likely and the sooner such versions will be developed.
Why even bother? I find that obtaining and tracking software licenses at work is very painful. Using free software as much as possible, means that anything non-free is 'required' and provided and so someone else will deal with the licenses. So I use 'free' as much as I can. Maybe I save money, maybe I don't. But I save time and aggravation. The relief is palpable.
I'm not sure of the time scales involved but you can make ice this way in the desert.
The time scales involve mostly the quality of the insulation and the night-time temperatures. The reachable drop or delta from night temperatures depends on the quality of insulation. Straw and what not? Maybe 20 degrees.
I do work in the CDMA industry... and used to work in the GSM industry before. I know what I am talking about...
There are no SIM cards in the US for any technology.
Evidently you don't know as much as you think you do.
A simple search on e-bay US would have shown a lot of sim cards for use in the US. My T-Mobile phones have SIM cards, and T-Mobile has had me switch cards between phones to troubleshoot issues in the past.
Cingular (was AT&T) GSM phones also use SIM cards, and if you have an unlocked handset, you can switch it betweeen Cingular and T-Mobile just by inserting the proper SIM.
installers would have to check what filesystem they're installing to, and behave differently for NTFS vs. FAT.
No, that is STUPID!! I rip that idiot cruft out of code all the time.
All the installer has to do is try to rename the file. If it works then do the install properly. If the rename fails, then it does the old reboot style of install.
You have to have that error handling code in there anyway (since a file might be explicity locked even on NTFS and you had better not be stupid enough to fail in that case). There is absolutely no reason to add file-system sensitivity and pretend you know what does or doesn't work on every possible filesystem.
My co-workers are lucky I even bother to use descriptive variable names. That's a huge improvement over my last reviewing quarter, when I started with variable a and worked to z, then started with aa, ab, ac, etc.
What if your mouse crapps out? How do you put in a new one once you take the old one out, and the socket is now filled with nice, non-conducting oil?
What, it is full of nice conducting air now? (hint, connectors have contact pressure, so as long was what covers the contacts moves under that pressure, there is no problem)
And what about any oil-soluable compounds in the electronics? won't they pollute the oiltank? And if resins and other organic compounds do leach out into the mineral oil bath, won't that slowly change the properties of those components?
Contaminates in the oil and oil-soluable bits would be my biggest concern.
Is it enough to download the file called 'source' at sourceforge, if it is there, or is it better to get the source code via CVS? Are there drawbacks to either way?
Usually downloading the "source" release would be sufficient. Some projects do not make a source release, and CVS is the only alternative. Some do not use CVS but do provide a source release. I usually grab the source release if it is available, unless I know that CVS is more current.
