Been doing virtual machines since vmware workstation 1.0.1
Now a days, I have a 1090 phenom 2 x 6 as my home server.
Machines for routeur, web server, download machine and a lot of other stuff are all virtualised. Works awesome and as I live in cold climates, the power bill is nill most of the year as it costs the same as the electric heating to replaces.
I would suggest staying away from KVM and going for Xen instead. KVM a crap support when it comes to USB as far as my experience is concerned. KVM is the most resource efficient, but Xen is a lot more stable and mature. It also works a lot better for USB and PCI devices.
Be very careful on what hardware you get and make sure you research it's support for PCI sharing, as this will be the most difficult bit and is what will make or break your rig, so to speak.
ATI as the lousiest support for visualization in the world, so I'd suggest sticking to Nvidia cards for graphics.
Re: I ditched IE in 2000.
Hey may be ignorant of what it's like now, but his description still fits with the modern version. Didn't it fail to render even msn.com properly when IE11 launched?
Re: From an environmental point of view...
Depending on what you have to support them, a fleet of robotic electric cars could be rather interesting. Just need some good powe rsource for all that juice, preferably not burning fossil fuel. I'm very curious to see what'll happened with the the Quebec gouv's plan for electrification of transports.
Re: Flatlander thinking
That makes the robot itself bigger and makes for more small parts having to carry a lot of load as it moves, making it more likely to break. I expect it would also make dealing with the recoil of taking a pad off the surface harder, but IANAE
Re: "tasteless" jokes
Come on, Rob Ford as jokes with taste. From the looks of him, probably very expensive taste too.
But I guess it's all just a puff of smoke ...
Or they could have absolutely nothing against him but needed someone to blame and now his life is ruined even if found innocent.
Re: @Tom ... Take 'em for every penny you can boys.
This was commercial use, not parody.
A parody is making fun of something, usually with some kind of reason/message in it.
This was using a crap version of the music with replaced lyric to sale a product, ie advertising.
The BB have a really good point that the PREEMPTIVE lawsuit by the toy maker is just a way to get even more publicity out of the affair is proof of ill will.
I hope they bankrupt the backers of that business.
Quebec as it's share of nice light free zones you can go to and look at the stars. Unfortunatly, the part of this wonderful province of Canada I live in as, this time of year, is not good weather for star gazing.
Either it's snowing and the temperature outside is survivable if it's not too windy or you have wind shelter
Clear skies and -30C actual temperature outside (as the mercury calls it) and of you are lucky, not windy. Real lucky ...
Just another post
Started reading and then I figured I wanted to ask a few more questions and would make one assumtion. As you spoke about having a rack, I suspect you want to use it. As such, I'll assume you want something that will sit inside the same rack. So physically close.
Now the questions.
First, what kind of storage do you have? As in, what kind of OS do you have on it.
The reason I ask is you might want to actually make use of it. If so, I'd suggest you look into what kind of connectivity you can get to it. This is where the OS becomes important. No clue if you can do this in windows, but it's relatively easy to get either iSCSI (over ethernet, 10g would be best) or fiber cards working on Linux. If your storage boxe(s) have the connectivity and/or free PCIe slots, you can use it for your virtual machine storage. Then you can just skip spending on disks and use those you have.
Getting a motherboard with more then one PCIe port migh then be a good idea, so you can get good connectivity. My personal favorite would be iSCSI over 10G, but that's only because I have made it work on 1G and it was almost trivial. I suggest using the raw exported devices for VM disks instead of sitting things on a file system if you can do it, as that avoids some overhead.
For CPU, I would suggest number of cores over processing power, so go AMD. As this is a `for fun` setup, this gives you better interactivity between machines, as you can limit the number of CPU each can use. Memory is what most people will recommend you spend a lot on, but it depends on what kind of machines you want to run on it. Get a pen and paper our (or notepad) and just add up how much you want to give each, then give yourself some room to play. I have 8G on my home setup and it's swap as never been touched running 8 VMs.
If you want a nice easy GUI to play with, Virtualbox on Linux is nice. You need to do a litle command line to setup the virtual disks if you want to use raw devices, but other then that it's simple as pie.
If the command line doesn't scare you, KVM all the way. The only downside I have found to KVM is the lack of proper USB support. If you do everything over the network, that's not an issue. It's a lot more efficient at idle, so your machine will burn less power when it's not working, as less CPU cycles are wasted. On my own home setup, it's a constant 20W less draw on KVM then Virtualbox at idle, according to the UPS anyway. I've also found you could get a litle more CPU power at full use with KVM then with Virtualbox.
On the legal side, remember that microsoft might not like you using home versions inside virtual machines, but I haven't bothered to read up on it. My understanding, and I'm not a law person, is you can use pro licences fine, as long as it's 1vm, 1 licence. No clue if they put actual technical barriers to it or not. Linux of course doesn't care and works wonderfully under VMs.
Re: Thanks Google
I wonder if it'll be as bad as the IE one where it lets commonly downloaded malware like regcleanpro pass by without saying a word, but then claims files downloaded to fix infections, like adwcleaner or combofix, are malware because they don't get downloaded as often?
Re: I'm divided
What do they sale? Networking gear. Everyone all the sudden being able to use video technologie for free is going to, they hope, get someone to make a real killer video app that will force ISPs to upgrade a shitload of kit because 800kbit/sec upload from the client just won't cut it anymore.
I guess that's what they are thinking anyway.
Re: BB's saviour?
Well, do consider this. One of the big saling point of android phones is that a lot of the apps are free with add support. Those adds are google adds for pretty much all apps I have used so far. YMMV, but I can see google making cash there.
Re: French Police Had The Right Idea
You need to brush up on your linux. Almost all major distributions now support in place upgrade. The rest no longer have a release cycle, they just keep all the software updated all the time, meaning there is actually no "big upgrade" to do. The rolling upgrade on a lot of them is actually rather awesome. They just need up update the install media every now and then.
Not really surprised. If at least d-link followed wifi standard properly, it would be a huge improvement. The number of dlink routers I've seen that "work fine on the old laptop", but for some reason the latest shinny laptop or tablet they got just can't connect to it would be funny if it wasn't so sad.
4k is already pointless
Consider this. Right now, on most big screen tv, if you show a modern DVD vs the BR version, most people can't even tell the difference in picture quality. 4K will be the same thing. We are already hitting a wall in term of TV screen quality. The difference between 1080p and 4k won't show, at all, in any living room.
Not only that, but the 3D fiasco already showed people aren't going to flock to get a new screen anymore, as the perseived increase in image quality by going to HD was more then enough for most of them. Besides, who as a grand or 2 to spend every 2 or 3 years just to upgrade to the latest studio mandated fad?
Guess someone at BB needs to read el'reg
Some of the larger chains here, and even some of the smaller ones, found a very nice way of dealing with the issue. It involves a rather well tried method of bolting things down. In this case, the P.O.S. terminal. (surprising how many other words I can think to fit to those letters)
This came about after a series of actual replacement of terminals while personel was distracted, usually helping an accomplice with something. Doesn't fix the crooked owner problem, but that can be more easilly spoted when people who start complaining all went to the same place.
Re: I'm a MSFT Fan But.....
How is that different from what actually happened?
Re: "Depends on what the meaning of "is" is...."
Here's an idea. ANY time someone in power says "it depends on what the meaning of X is", you throw them in solitary confinement for 6 months with nothing but a dictionary to read. See how it goes after that ...
"doing things that machines are probably better at doing"
I love how he even admits he as no freaking clue what he's talking about. Yes sir, machines are "probably" better at it, once the humans have properly programmed them, and you'll need humans to look after the automated machines too. Let's call those "system administrators" ....
"The search for more money"
Re: What goes around, comes around...
You are blinder then most if you actually think the ballot box works, especially if you are in the US. You're under a 2 party system. Both parties lie to you and have absolutely no respect for the promises they make. So what are your options again?
I use my credit card for pretty much everything I can get away with. Why? 1% cash back in the form of points I can use to buy groceries, 2% when I actually do the groceries and some extra points for using re-usable bags. Everyone eats and as it as zero annual fees, it was the best kickback I could find. How much does the card cost me in interest? Nothing, because I pay the balance entirely at the end of every month.
It's kind of nice to get a 100$ of grocery and only pay 20 at the register.
So, it won't be here for at least another 2 years. And that's just for the kits to start being made, never mind actually being put in the home. In the mean time, even in Quebec, we're seeing fiber role outs pretty much everywhere, even less densely populated areas. I somehow doubt this will see any kind of use, ever.
My vote is "it's already happening".
Re: A6 probably, not A5X or A6X
Being in a court battle with the people that actually provided most of the technology probably isn't helping either. Think we're starting to see what happens when the lawyers take over.
I think it's interesting to be in IT period. A lot of shifts going on right now. Back, middle and front end, as we move back to basically the old mainframe model, on a much much larger scale, in the buisness.
What's disturbing is how it tries to force itself into consumer products in sometimes very stupid ways. Think a router that needs the internet to be configured in the first place, a little while back. I'm also thinking some people who figured it would be a good idea to have all the processing done for games on servers. Both stupid ideas.
In the business, I'm a little worried it often ends up just leading to uncontrolled sprawls of unknown systems with no one competent taking care of them, all sitting in the cloud and getting charged to some company credit card.
Still, all this shift in buzzwords still all sounds like the same kind of challenges we've faced before, only with new buzzwords and with less technically savy salesmen getting in the way of what's really going on.
Re: Not a problem
Now wouldn't THAT be hilarious. I imagine it would make the greedy execs that made this happen wonder what the fuck they were thinking. That, right there, just might sound the death bell of patent trolls. Too bad it'll never happen.
Re: Another nail in the MS Office Coffin...
Actually, it does as have an "access like" tool. The real nice thing about it, I will admit, is you can use it to connect to a number of databases as well, so it makes a nice, if very basic, table design tool too if you want to use it like that.
"There's still a large OpenOffice user base, but the increasing industry support for LibreOffice has got to be worrying for the original squad."
Well, not really, as the original squad left openoffice.org, due to Oracle basically not saying ANYTHING for a year or so. That, as you so nicely said in your article, is how libreoffice got started.
Come on el'reg, at least be consistant inside the article ;-)
Most secure OS is one where the most vulnerable element, located generally around 18 inches from the screen, as had proper training in the basic skill of reading.
Unfortunately, those are surprisingly rare.
It's not being handled by the CPU, it's handled by the dedicated memory controler. The reason it's better to have it done in hardware instead of by the compiler is it makes for less work for the CPU, not more. The idea being that the CPU having to do less work means extending battery life.
This would work well in Quebec, where we have a lot of power generation capacity that's clean. Maybe we could stop giving the power away to compagnies owned overseas and use it ourselves ...
Re: Answer me a question...
and probably cheaper then releasing a product people actually want ...
A sample of 1
I've actually played with KVM, Vmware and Virtualbox before I built my last system, to see how each worked.
The command line junky in me loved KVM and could live with Virtualbox. I hated vmware on that account, at least on the products I could try then. But in the end, the one thing that impressed me the most about KVM was the number on my UPS that indicated energy usage in Watts.
KVM was easilly the most awesome one on that account. On the same machine, at idle, the machine would consume a consistant 20 watts less energy then with either of the other 2, making it drain 115W instead of 135W with the other 2.
Doing a performance benchmark in the VMs afterward showed the footprint of the virtualisation layer was also very different. KVM would cause around 5% overhead and was extremely consistent, compared to between 8% and 15% with the other 2, with a lot of fluctuation, not always for obvious reasons, or any I could find really.
A sample of 1, so YMMV
Re: Of course the baggage theft can continue as usual.
I'm more inclined to think "not many" would be an optimistic figure. The actual number probably starts with a Z.

Eh hoser, beer typing will get you kicked off the BBQ team!
There, go learn some history.
You'd think so, until you stop a second to think about it. The contract user can't leave easilly, or without a stupid high penalty, where the pre-pay service can just not get a card next month.
You mean how all the BIG car compagnies still haven't payed it back? Think your money was better invested there?

Re: Well (@fmaxwell)
Please go back to the natural history museum to argue against evolution. You will be less of a nuisance there. The fact that humanity, as a whole, is emitting something like 10x the amount of CO2 that every single natural process on the planet combined does as consequences. Hiding your head under the sand won't change that. Let those of us who would like our specie to survive the next few hundred years handle this and go back to praying to the big man in the sky for salvation.
I must admit, seeing microsoft complaining about secret API that aren't documents and not made available to competitors as such a sweet smell of karma it's hard to resist. I'm sure the people who worked at netscape or Corelin the 90s are having a fit of laughter right now.
Re: They have the authority
I suggest you look up what Benjamin Franklin had to say on the subject. It's rather interesting.

As was pointed out earlier, any credibility the Ambassador add vanished the instant he said anything about the Lannisters. After all, claiming moral high ground in this way means condoning stealing of power (the crown), murder, rape, child abuse ( poor Sansa ) and a host of other wrongs.
O wait, he works for the entertainment industry. That's normal then I guess.
