Heh, have you ever worked in a retail environment? I have. I've worked with "the 16-year-old running the cash register...stoned." It's Not Good. Yeah, you might think that, gee, you're just there making money from The Man(TM) and you'll do the marginal work it takes to get your money from The Man(TM). Maybe it's because I worked in a retail environment in a small town, but the funny thing is, people start to associate you with that business. If you just do the bare minimum for The Man(TM), people start to talk. If you go out of your way to help, yet again people start to talk.
My point is this. In my experience, after the initial drug testing, most businesses only test for a reason. I guess Home Depot goes further. Is that a problem for you? Then don't shop there and don't work there! If everyone felt that people should be able to smoke pot, Home Depot wouldn't have any business.

Yeah, they do so much for the community--such as keeping their employees in poverty, supporting right-wing organizations, forcing mom-n-pops out of business through predatory pricing, receiving corporate welfare through their (some)drug-free workplace program, and jacking up the price on plywood after a hurricane takes out half of Florida.
The relationship between (some)drugs and workplace injury has not been credibly established. However, a recent study on driver impairment shows that the top three factors are:
sleep deprivation
alcohol
other drugs
Ahem. Why don't employers test for alcohol? Because the Drug-Free Workplace Program offers federally-subsidized discounts (up to 50%) on Workers' Compensation premiums for companies that do (some)drug testing. The politicians have somehow convinced America that alcohol is not a drug! As far as I know, (some)drug screening only occurs in "the land of the free". Ironic.
So, next time you're in a Home Depot, beware of employees who may be drunk to ease the depression from wage slavery, or who are sleep-deprived from having to work a second job to make ends meet

VM stands for "virtual machine." It gives the impression of running on a real piece of hardware. VM is so good at virtualizing the machine, it was used for OS development. (It really started as an internal OS development tool, not a standalone OS.)
A hacker working on one virtual machine can't trash a different virtual machine, or the root machine (which may also be virtual). It's like process protection, but extended to the entire OS environment.

I think this is part of the problem with GUIs and the attempts to implement them. People think a GUI is all that is needed for ease of use. More thought needs to go into it though. For example Mac OS places CDs and Disks, that are inserted into a drive, on the desktop automatically. I think this is superior, in terms of ease of use, to the way that Windows makes you go to the particular drive and click on it to acces the CD or Disk. There are hundreds of decisions like this one that affect the ease-of-use of the OS which are beyond having a good looking GUI. It is also important that the GUI be very powerful and allow you to do pretty much anything that you can do with a CLI. If the GUI doesn't do this then it is simply a pretty picture to look at.
the only thing that's holding it back is the lack of powerfull, easy to use applications.
I was actually going to get into this on my first post but decided not to. I guess I'll get into it now. Yeah this is a big problem for Linux and it is a very hard one to reconcile because of the philosophy behind linux and open source. Easy to use software is usually made for consumer platforms which right now linux is not. It is usually made by companies trying to make a profit too. While it is yet unknown if real sustenable profit can be made from open source software most for-profit companies seem to have made their mind about it. They think it is not a viable option. Since the crowd that uses linux is for the most part willing to use vi or emacs instead of M$ word, the for-profit companies think that no matter if their product has a different approach on a task or targets a different use the Linux crowd will use a free solution for another problem if the solution is close enough to the one needed. Since there are geek tools available in Linux for almost all problems companies dont think they can make inroads into the GNU/Linux market. Adobe probably thinks "Why port Photoshop to Linux since they will just use GIMP instead?" Photoshop could be a better product (I don't know if it is or not I use neither program) but Linux users will probably stick to GIMP. After all Photoshop costs $600 and GIMP comes with many distributions. So for-profit companies are afraid of open source, and they do have reasons to be afraid. They feel more comfortable with close source OSs because they are part of the old boys network and play by the old boys network rules. If you look around the few big companies "embracing" open source are harware companies which have been resenting the profit margins that software companies get and the leverage this gives them in the stock markets.

I can sympathize with coworkers who pawn off work. Unfortunately, they don't need to be drunk to do this.
If a person was drunk you'd think that would show up in there prior experience, and perhaps the drug test. Sure they can sober up for an interview or a drug test, but how are you going to find that out in a credit check?
Secondly, we already tell private businesses how they must conduct hiring practices. In particular, how they may not conduct it. I'll argue that it's good to have anti-discrimination legislation. I've talked with hiring managers who say it's illegal to ask a company listed as a reference for more than dates of employment, and salary/wages. This is to prevent blacklisting. So if you can't get that information, which would be much more directly relevant to a hiring decision, why should you get the highly indirect/speculative and personal financial background of a candidate?
Further, companies and organizations have a right to keep trade secrets, and such, but why privacy? Companies and organizations are by nature far more exposed to the public than people are. For instance, financial statements are public in the case of corporations, and some companies. In short, private businesses aren't as private as you may think, but people are, and need protection.

You are missing the point. Every user gets their own virtual computer to play with. They have root on their own computer. But they do not have root on anyone else's virtual machine (nothing to do with java :-) In fact, they cannot access other people's machines at all. Basically, it's almost as if every user had their own physical box hosted at Telia.
Telia does not have to maintain any of these virtual machines. All they need to do is create one when a user signs up. After that, the user has complete control over their own box.
This is really cool. But the real question is whether it's cost effective. 1500 individual boxes would be definitely several orders of magnitude faster than a single mainframe.

Re:Linux on the mainframe (Score:1)
I agree that this increases prestige for Linux. Mainframes have gotten an extremely bad reputation for several reasons that Linux would address.
1. Ease of use: Mainframes have historically been hard to use and/or interface with. Anyone who has worked with MVS or what is now known as OS/390 and next Z/OS would remember horrible things. Examples are JCL (Satan's version of a batch file or shell script), Record based file systems such as PDS's, VSAM datasets, and the like which either can't or are hard to directly copy or interface with, and must be preallocated before use. No GUI interface, and limited command line capability in ISPF. There is an X Windows capability via the UNIX services layer, but applications and utilities haven't been ported there much.
2. Culture--This is good and bad. Mainframe programmers tend to be very disciplined. They can also be resistent to change (ie. stubborn), slow because they're disciplined or because they're just slow.
Yet these are just the OS and cultural problems. This is what mainframe architecture gives and has given almost since conception.
1. Reliability. If your DASD(permanent storage), CPU or other device goes out, you can take it off line, and replace it without taking the system down. In some installations, IBM will automatically be notified of this failure and send out a service person to replace it without even a phone call. Try that with an INTEL box of any kind.
The architecture is also very stable, in that the instruction set hasn't changed much over the years. This allows it to be perfected as it grows. You can still run programs from 25 years ago on today's systems (at least in many cases), without recompilation (though it won't be fully optimized).
2. Scalability. Yeah, it's a single box. But even in its infancy it had a processor complex with the option of containing multiple processors, each of which has been designed for this purpose. You can also many mainframes and form what IBM calls a sysplex. Processing power can also be partitioned into what is known as LPARS, meaning multiple (possibily heterogenous)operating systems can be running simultaneously on the same system. Processing power can be split in a specified proportion, not necessarily equally. They also won't interfere with each other because it is not done at a software level.
All this gives Linux a reliable hardware platform, which in turn makes Linux look more credible.

Why linux will never be truly mainstream... (Score:1)
Companies want someone to blame when software fails. They want to be reassured that their software is good. They pay thousands of dollars for this reassurance. Now, what's sounds more reassuring..software produced by a company used by 90% of the world, traded publicly..or software created by a few guys in their spare time for free. In the case of free software, they basically receive it with no guarantee it will work properly. Most companies will not gamble in this way. It's corporate culture, and that's bigger than most governments, much less the comparably puny "free software" movement. Indeed, look at telia going with IBM, and you bet IBM is providing support for all the software on the machine. It may be linux, but i doubt it's the same thing most people on /. use.
Furthermore, most software companies arent going to bother porting their software to linux or developing for it. Why? Because of the linux culture. Linux culture is based around the GPL, which is about as business-friendly as communism.
That's right, the GPL is the licensing equivalent of Communism.
Now before you turn your ears (or eyes) off, realize the similarities between them. I'm not anti-free software, and i'm not anti-communist. They represent moral plateaus, and i think free software is excellent. But no company will ever base their product line, or even dedicate that many resources, to developing for a culture that's based around the GPL. It enforces that software must be free. Business is about making money. Therefore, something inherantly free, does not go well with the profit-needing business. This is why corel, adobe and other big names are dropping their linux programs. This is why companies like red hat are sliding into danger..investors have realized the fundamental flaw of combining making money (business) with something you cant legally make much money with.
So how does this all tie together? Well since big companies are going to barely support linux, if at all, other companies arent going to want to invest their critical systems in software that's unsupported by other big companies. This will all limit the migration to consumer desktops. Consumers will want to use the same software they use at work.
And that's the catch. Linux will always have it's place, as it should, but it will never dominate. And it's just downright dumb to base your business off it.

I did not say, "provided the security is good enough." The security already is impenetrable, right out of the box (er... crate). No OS patches, no BugTraq-reading. The trusted sysadmin would have to break it on purpose to do anything. And if you can't trust your sysadmin, clustering won't help.
It is far more likely that a clustered system would utterly collapse than this one "basket" would. Here is an anology: Let's say you have one billion dollars to move from point A to point B, in $20 bills. You can either load the bills into a fleet of NYC street taxi's (with the doors locked), or into a truck armored (and weaponed) like an M1A1 tank, and four completely redundant engines. Which would you choose? Multiple, unreliable, boxes that have been proven notoriously hard to secure; or one single, easy to administer, rock-solid box, with security that has been proven over decades to be bullet-proof.

On another note with the Home Depot... I just got a call from my lawer telling me that The Home Depot has settled out of court with me for a whopping $1500 to compensate me for the broken finger one of their employees was kind enough to give me.
All this aside, I would imagine that having Linux on their cash registers would be a first step towards the Linuxing of all their computer systems... I guess this could allow them to change prices on the fly... Someone updates the cost of a hammer in Tulsa and across the Home Depot network, the increase ( or less likely the decrease) in price is instantly updated on all their cash registers...
Of course, I will want to get my hands on one of these Linux cash registers because I need one that can preform complex boolian operations, to sort out the tax structure here in Canada, as well as keep me entertained through a full T1 internet connection.
Who'd a thunk selling screws could be so complex... Will we now have to refer to the Home Depot cashiers as Cashflow System Operators?...

Software, free or proprietary, needs users in order to thrive. 90,000 cash registers nationwide in a high-availability situation is a lot of users.
I gather from the TechWeb article that Home Depot contracted with Red Hat for some or all of the work on these cash registers. It's not clear whether HD and/or RHAT have made the changes for the "stripped-down version" of Linux available. Other businesses may be able to benefit from their work.

30,000 Linux OS images on a 390 is no harder to manage than those as MVS images, and not that much (sic) harder than a single one. Sure, there's a lot of user accounts to manage, and a mainframe port brings in complexity issues that aren't important for a one-per-desktop box, but you certainly don't have issues like 30,000 individual root passwords. It's a hell of a lot easier to admin than a Beowulf cluster.
Lots of users with their own image of a shared (and protected) OS is what mainframes are all about.

Also, it is FAR more likely that something like the power company or the outside net connection will go down before the mainframe itself fails. These are designed for ZERO downtime. So a company deploying one of these is far more likely to lose sleep worrying about external systems than the mainframe itself.
Re:Linux on the mainframe (Score:2)
1) JCL is not equivalent to a batch/shell script, more like a control file that tells a program what files to use, so is more like, say, smb.conf. Try telling me that that is easy to use. The closest thing to (g)awk on the mainframe would be Rexx, which, although not perfect is a no-brainer to get things done and has almost no learning curve (unlike anything Unix-related). And things like the ISPF Edit facility is several times easier to use than vi or Emacs e.g. want to change one string to another: 'c foo bar'. What's the vi equivalent? Dunno, and I can't find it in the extremely confusing man page, although it will be some 733t gibberish no doubt. ISPF help is a lot easier to navigate. ISPF does a have a GUI facility, but few companies are prepared to fork out for it.
2) Generalisations like that are exactly the same as saying that Unix coders all have huge bushy beards and wash once a month whether they need it or not.
OS/390 is several orders of magnitude better than Linux, but it costs a great deal.
1) Got to agree. mainframe hardware management is superb.
2) You've contradicted yourself here. Mainframes can very easily be clustered together.
In conclusion, you obviously last worked on a mainframe when IBM was still getting used to not being a monopoly, the improvements in software and general attitude to customers from when I first started 11 years ago is great.
Last thing, don't think I'm anti-Unix (I'm posting this from Linux), I just get annoyed when people forget all the irritating things about Unix when they criticise mainframes.
