Why is there always a focus on the negative side of automation? It really means less work, same productivity. Humans no longer need to work as hard to produce the same quality of life.
Automation is good, it's the way employers handle switching over to automation that sucks. As soon as a new system is installed, they go fire a few hundred people...
If it was handled better, moving as many people as possible to new positions rather than firing them and hiring someone else, and employers smoothing out the curve or high/low demand rather than hiring/firing large numbers of people on the spot, it wouldn't have nearly such a negative connotation. It just gives employers the opportunity to treat their employees a bit worse (eg. using the threat of impending automation, to cut wages, benefits, etc.).
Actually, I'd call LVM the long-term pain. For all it's benefits, I don't want my servers to become unresponsive when large files are being written. Doesn't happen on regular partitions, only with LVM.
It can be done with rsync, or a drdb device can be used to sync with the server (it can be created without reformatting the partitions, but you still need to make some changes like shrinking and/or moving the data, which might destroy the data if you don't know what you're doing).
DRBD does not require resizing partitions. The meta-data can be kept on a small partition on an entirely different disk if you so choose. At 128MB each, with minimal data being written, you could well plug-in a small USB Flash drive, and put the DRBD metadata for numerous partitions on it, without touching any of the hard drives.
Then, on the secondary DRBD system, you just "connect" the relevant partitions when a snapshot is desired, all changes get synced up to date, and then disconnect whenever you like. It's better than a snapshot, since it's on a physically separate system. If you had a large enough hard drive array (2TB SATA drives are cheap), you could even have a single server being the "DRBD secondary" server for dozens of other servers, receiving "snapshots" periodically, and perhaps, automatically...
2.4 kernel systems? Are you running Redhat 6? You know, from the turn of the millennia.
Redhat 6 was a 2.2.x kernel. So was Redhat 7. While the VER FIRST release of kernel 2.4.x was indeed right around 2001, the most recent revision of 2.4.x was just 4 months ago.
you can do what you're trying to do with rsync 'snapshots'.
Not really. There's no atomic rsync snapshots, so while one file in the "snapshot" will be from 12:01, another file might be from 12:15, and depending on the application, the two files might be hopelessly irreconcilable. In fact there are programs like "VSS Backup Helper" to allow your rsync snapshots (on Windows XP or later) to actually get an atomic snapshot, by using said VSS features in Windows, which is being asked about. What's more, rsync operates on the file level, which is hopelessly slow... Run rsync on a mess of small files with hundreds of thousands of folders on a 2TB+ partition, and watch it take (literally) days to complete.
Chances are you'll have to upgrade before this stuff even works for you, though.
Rsync runs perfectly fine on a 2.4.x kernel. It'll run on a 2.2.x kernel, too. Hell, I've ported rsync to ancient proprietary Unix systems (using GCC2.9x) with minimal trouble.
What's with this ageism? You think old software bit-rots if left on it's own? This isn't Windows ME we're talking about here.
if it would mak you happier, then they could tack it onto your property taxes, and solve the problem....
Why is it that anti-tax idiots cling to the constitution to support their goal of never supporting the government they benefit from, and then ignore/dismiss the same documents and relevant laws when they do oblige them to pay taxes?
Yes, they HAVE TO "tack it onto your property taxes". The "problem" is that they are breaking the law by trying to do otherwise.
No? Turned sideways? Laying on it's side? Still no room? I'd be inclined to run longer cables (in fact I did), rather than get a mini-system to fit in a cramped space.
Also sound is a concern. the PC is louder with the fans but I have a louder sound system downstairs to compensate. I prefer having the silent revo upstairs.
The larger the case, the better your chances of making it quiet, NOT the other way around.
Tower PCs the size of a labrador retriever are 90's technology.
Actually, they're 80's technology, but that's no reason to get rid of them.
Cars today aren't substantially different from designs in the 50's, and yet, nobody is clamoring for drastic redesigns.
Honestly, unless you're in a brutally tiny apartment, why do you care how big your PC is? Put it on the floor, out of the way, and forget about it. Sure, it's not stylish, but it's much cheaper than any alternatives, and it offers extreme flexibility should you want to add some new devices to it. What happens when you decide you need more space, better graphics, and next-gen WiFi? Buy a whole new system, or drop in 4 expansion cards? Oops, system's too small, no room for those.
Since most people's objectives are focussed on results, not security, if you try to make an operating system or application suite secure, people will find a simpler, more direct way of achieving their goals.
Security isn't just locking-down file permissions. worms don't spread around the internet by hiding in legitimate EXEs and overwriting system files. Proper code auditing to eliminate many of the simple code bugs (which are later found to be exploitable) would make a huge difference.
We know what a secure operating system for the year 2010 will look like. It will look like VMS from 1995, for all the reasons discussed above.
Funny you should mention it, because VMS is a very good model. Being a microkernel, very little of it is privledged, so all but the 200K of code in your basic kernel can be full of bugs, and yet not be exploitable nor even threaten system stability.

There is no upper bound on the number of logical partitions you can have
Logical partitions are not partitions at all. Hence the name. You could put logical partitions on a GPT, a tape, or anything else...
When PCs came out, there were no logical partitions, just as there aren't with GPT, YET. As soon as they're needed, they'll be standardized by those who need them...
It has been suspected as being bad sense the 1930's but there is no direct link to it causing any notable issues.
"The first evidence of the estrogenicity of bisphenol A came from experiments on rats conducted in the 1930s, but it was not until 1997 that adverse effects of low-dose exposure on laboratory animals were first reported."
It also seems to me that in 3 generations we would have seen a difference or at a minimum science should be able to say "It causes XXX"
I've got one:
"Bisphenol-A causes you to develop smaller genitals."
Any material in contact with food that has such a confirmed, physical affect should be eliminated, nothing else needed. If it was some form of medicine, fine, it has side effects. I don't want my food, or it's packaging to have medical side effects.
Despite all this, there is an upper bound to the number of partitions you can have (512 I think), which is not the case in DOS tables.
WTF are you smoking? For someone whose supposedly writing a boot-loader, you sure don't sound like you have a clue...
DOS partition tables have an upper limit of FOUR (4) partitions!!! Got that? Not unlimited. Not 512. FOUR (4)!
The hack to get around that limit is an EXTENDED partition, which then contains "logical" partitions. I doubt 512 partitions is going to start looking too limited any time soon, but when it does, someone will no doubt come up with a hacky cludge to work around that limit as well...
If they're such a great technology incubator I'd be interested to know what great new technologies they've incubated; Google Earth is about the most innovative I can think of.
Well, I do believe Google Maps pretty well sparked the Web 2.0 trend, and was pretty loudly revered by all who saw it when it first came out.
Google image search was a rather fundamental change, and GIS has become as much of a verb as Google. Others have since copied it, but before GIS, searching for images was vastly more painful.
I'd suppose their back-end technology is pretty good as well. Containerized data centers, et al.
I don't want the extreme headache of manually updating 12 SDHC or CF cards. I don't want 12 individual stupid yearly subscriptions to some internet ripoff company that'll probably go out of business and make my investment obsolete the week after I buy them.
Well, since a 1GB digital picture frame goes for $60, which doesn't require a fancy video card, and can be updated via USB, I'd say you've got an unnecessarily expensive idea there...
Now, USB has a strict 5 meter distance limit, but there are some devices that claim to extend that out substantially, though I recommend testing carefully.
Never has been, never will be... ARM is popular because they're very low power, while x86 is not. ATOM is doing better in that respect, and ignoring the power requirements, vastly outperforming all ARM chips available.
ARM has been fooling people for many years now with the same old MHz myth Intel used to use. That nice 1.2GHz ARM core is only getting perhaps 1.2MIPS/MHz if you're lucky, while even an ancient pentium3 does 2.8MIPS/MHz. Modern x86 chips with various incarnations of SSE absolutely wipe the floor with ARM, with astronomical MIPS/MHz ratings.
And it's not like that's something they might work on... ARM has been around 1MIPS/MHz for a very, very long time. The 1.2MIPS/MHz is actually their new and improved performance.
Shame, as my ARM-based desktop machine was incredibly fast.
People have a hard time differentiating between hardware and software. When their computer crashes, they don't know whether some program is badly written, or if the memory is flaky. The same is true of performance. I'd be willing to bet an obscene amount of money that this "incredibly fast" "ARM-based desktop machine" was running a highly tuned OS. Install some common OS like Linux on an ARM system, and an x86 system, and prepare to be in awe at the performance of old x86 CPUs most of us throw in the trash, because ARM just can't match it. PowerPC is the only architecture commonly found in embedded devices that can come close to competing with x86 in performance, which is why it's still the undisputed king in high-performance embedded devices, though ARM is certainly trying desperately to integrate enough DSPs and extra cores to compete with PowerPC in that space.
That's the most incoherent rant I've heard in here in quite a while...
Replace all the coal power plants with Nuclear, and it won't help one bit to prevent OIL SPILLS. Other countries have nuclear instead of coal, and they are just as dependent on oil as everyone else.
its a damn battery attached to a damn motor. its really not that complicated.
Get back to me when you've put together a few car-sized Li-Ion batteries. Simple.
we haven't used them up to now, because gas has been so cheap. its not going to be so cheap, ever again
It was more expensive in the 70s. It's much, much more expensive in other countries. Other countries have cheaper electricity, better electric grids, etc., etc. Note that even with all these combination, not one of them is free of oil, Nuclear power plants or no.
so now you figure the rest of the story out with your boundless imagination as to the future and the role of electric cars in them
I have no problem seeing what the future likely holds. You, however, have a severe problem with your reading, having a rational discussion, and really have no sense of the reality of the world around you.
But hey, what do I know? A few nuclear power plants, and all oil spills will stop, and a week later we'll all be driving around in our $100 electric flying cars.
If you hold up X as an example, it needs to work as an example... End of story. France and Japan are actually proof that Nuclear power plants everywhere will do NOTHING about dependence on oil.
Yes America put a man on the moon - but what have they done SINCE then,
Hmmm... Numerous Mars Rovers and other probes, Hubble space telescope, Spitzer space telescope, New Horizons on it's way to intergalactic space, put up and assembled a massive space station, etc.
Russia, China, and soon India all have more advanced space programs than the USA right now.
Umm, actually all of the above are more PRIMITIVE than the US' relevant programs. The fact that the space shuttle has been taken out of service doesn't change that fact. The US continues to launch plenty of unmanned missions.
China will have a *permanent* manned lunar base by 2025. They *will* do this, not just talk about it.
That's HILARIOUS.
China doesn't nothing but talk, extensively, about every topic under the sun. If you believe damn near any of it, you're a fool. China states, routinely, how their country is going to surpass all others in every possible pursuit on a regular basis. It never happens. Spouting crap is what they do.
Very shortly, your only way to get a human into space will be to beg rides from the Russians or Chinese.
Your weather satellite network is falling apart
We're all falling apart. Time works that way. As long as the weather satellite network continues to work, complaints about it are academic.
and your GPS network is being superseded by a more accurate European one.
We've been hearing that for, what, 15 years? The fact that the EU feels the need for one-upsmanship by duplicating the functionality of GPS at a ridiculous cost, for no benefit, is fine by me. Good luck with that.
I do have (the Linux version of) Flash 10 installed on my FreeBSD 8 amd64 systems and running it in a native FreeBSD amd64 Firefox.
Unfortunately, those of us on FreeBSD 7.x, 6.x or perhaps even below, are limited to Flash 7. And frankly, I haven't even been able to get that port to work. And that's even after I reluctantly accepted the need to have hundreds of MBs of Linux binaries installed for a single application...

No you shouldn't throw out a 33MPG car to get a 50MPG car.
