(Good in Theory, but we don't have a lot of water right now......)
To use your analogy, the GP ASKED to have a doctor look at his ass... and then felt dirty afterward.
If you ask for help with why you cant insert data into your db tables (or whatever) I'd expect your host to have a look.
What's a 'process network' and who exactly do you get to fix your 'process network' ?
A process network is the network the SCADA/DCS system and it's physical controllers sit on, usually segregated from corporate LAN with maybe the odd server that bridges between the two.... and to fix it, you call *ME*:-P Usually a Process Network is NOT managed by a sites I.T department, or at best they do all the IP allocations etc and then leave it the hell alone.
Assuming the above anecdote was even true, such an incident would never occur on a live system, and I'll tell you for why. You never update a life system - got that - never. At least in any competently run IT department.
Usally on a big system, you have 2 or more SCADA servers, with redundancy built in. Usually you take one server down, upgrade the software, then swap over and repeat, ensuring no loss of view or control, same for the controllers, most critical systems would operate redundant PLC's to ensure updates can occur. Therefore you CAN and often DO update live systems.........
re: 'qualifying the updates': Just how exactly do you qualify an update. Is an update the same as a patch or a bug fix. What motivates you to apply such qualifying updates. I mean if the computer ain't broke, then don't fix it.
By qualifying patches, I mean the vendor usually checks out stuff like windows updates, and assesses the impact in the system. You don't just go install the latest Microsoft hotfix for the hell of it, but I've seen it done....and I've had to fix the impact of that!
Updates are usually installed to fix/improve system operation. It is a common procedure and there are usually controls in place, but occasionally things go pear shaped.
Standard PLCs can be surprisingly easy to halt, Safety PLCs even easier.....but one would have hoped in a Nuclear Plant there would have been procedural controls to avoid this.
But then again I only ever provided IT services to the double glazing sector, and what do I know..:)
Hey, we all have different areas of expertise, this just happens to be my bread and butter!:-)
...although, after re-reading the story it's a little vauge...was he updating some random PC or was he actually updating the scada/process control software/firmware?
If it's the latter, I feel for him:-) , but you have to do your homework before going all patch crazy!
This is why you keep the IT nerds away from the process network.
I've had a whole plant lose view of it's system because some well meaning retard in IT decided to push updates onto a SCADA system without qualifying the updates....... never had it KILL the control side of things though....well done whoever you were, you've done well.
...is like saying they're the smartest European.. Hawking...Einstein.... oh, wait, what part of the world........hmmm
douche.

I've been looking at benchmarks to decide the fate of a website I develop for.
We are on Postgres8.1 right now, but I'm a MySQL fan....but I'm not finding compelling reasons to switch........
YMMV
Server Rooms make me sleepy...
All those machines.....all those fans....all that white noise......
YAWN....so sleeepy...
Zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
At the moment I funnel all traffic thru dansgaurdian and tinyproxy on a Linux box.
My kids are only young (6 years old for the oldest) and she's already on the net (Barbie sites etc etc)..
I'm pretty relaxed about things, but the one area that has me spooked is chat rooms etc (there's been an incident in our immediate family that has me this way..not paranoia).
The good thing about dansgardian is the granularity of control it offers...I can stop access to a lot of areas without too much hassle and I can easliy relax the restrictions as time goes on...
When the kids are older I will back off the controls and give them more freedoms, but #1 on the things to do list is talk to them about the responsibilities that come along with that.
By the time the kids are old enough to try to defeat the system to look at porn I hope that we'll be at a stage where theres at least SOME element of trust between us..... but at the age they are now, I'LL have the parental controls cranked right up...
In that case you might want to use Krita. Not as feature complete as Gimp yet but the interface is less exotic and it has its good sides.
I've been using Krita quite a bit now for basic editing.... it's pretty lightweight and easy to use.. I'm becoming a fan of it.
As per your comment, I've tried using photoshop recently too after 5 or 6 years of GIMP and I couldn't find any of the tools without a good search... I suppose it's what you know etc.....
Raid (any level) does NOT protect you from anything other than hardware failure.
If an app b0rks and starts filling your HDD full of zeroes then you have a nice redundant array of zeros. A lot of people I know have RAID controllers on their machines and have NO backup regime... scary..
You still need to protect yourself from data corruption!
I use backuppc running on a Ubuntu powered NAS box to back up my win and lin systems.
Someone I know really well..cough... likes a lot of UK television, and I...they...get it via other means because shows like Dr Who, Top Gear etc are nearly always a year behind... plus they don't show stuff like QI or Mock The Week at ALL...
I'd pay a provider for this if they got eps that were CURRENT, played in ORDER and not bumped for some sporting event or whatever....
I know fans of US shows get a bit miffed when they show 1/2 a series then roll in some eps from previous seasons or play a series out of order... Australian terrestrial TV is a fucking shambles....
We had a customer (a legal office) running a W98/W2000 site across a few hundred machines.
We then went thru all the options with regards to running software.
Without getting on my FOSS high-horse I explained the following
* The cost of MS Office over 200 machines was $x and the cost of OpenOffice was $0 * The fact that for the money you would get (alledgedly) better product support with the MS product, but there was a lot of info on the net re: OO/Firefox etc * The fact that they could go get a royalty free DVD of clipart and fonts from next door for $20 and the lack of clipart with OO wouldn't be an issue. * The advantages/disadvantages of differing email clients * The cost of an exchange server over the cost of a simple mail server on a linux box
As the machines we were providing all came with XP I decided not to go down the linux path, although it was raised by the customer and we did discuss it.
In the end, the customer is now running XP w/ Firefox/Thunderbird/OO and using apps like CDex and is quite happy. They were not convinced around and OSS or free virus scanning though, and we ended up having to install TrendMicro at their request. (Also there was an aborted attempt to run WordPerfect Mail 10, but it was a huge piece of ass and Thunderbird was rolled out site wide)
All done without either zealotry or what I would consider over-advocacy.
Sometimes the goods speak for themselves, there are some solid apps out there now that don't requre a lot of effort to promote.
Just be calm, rational, listen to the persons concerns, explain your position and you'll be suprised what comes from that.
No-one will listen to you if you go down the zealot route....it smacks of desperation .
(and as someone above said, sadly most people DONT care about DRM, using that as your sole point is futile)
When setting up my geocaching website I evaluated about 10 CMS systems, including Drupal, phpWebSite, Geeklog, Joomla, Mambo, PHP-Nuke, phpWCMS, phpWebSite, Post-Nuke, Siteframe, TYPO3 & Xoops.
In the end I found that Geeklog was the one with the most intuitive (to me) templating system and was the easiest to add your own code to. I found that most CMS systems are great out-of-the box solutions for doing what THEY want you to do, but adding custom modules and functionality is a nightmare!!
I wasn't expecting geeklog to be as good as it was!
Pah!
UYou guys don't know anything!
You should try driving thru Launceston at peakhour like I do every day!!
Some days it thakes 5 minutes to cross town........ thats right...5... I don't know how I cope with all the travelling!!:-)/lives 30k from Launnie//takes 25 minutes tops....suckers!!!
Mt philosophy is that if you aren't going to pay for MS Windows you don't get it - which is why most of the installs I've done are different types of linux. It's the same with photoshop - I'm not going to install a dodgy copy of it for anyone: if you just want to put a frame around the photos of your kids from your new camera on work time the gimp does the job.
I agree with you 100% on this point. How many people do you see in forums ranting about needing Office/3DsMAX/Photoshop who have actually paid for em??
I love linux because it is free and free as in unencumbered by drm etc)...
Open Office/Gimp/Blender are as good for me as a casual user.
* Hunting caches takes me to interesting places that I would never have seen otherwise. Pocket parks, public art works, secret waterfalls, funky neighborhoods.
* It's a community. Many of my friends are people I've met through geocaching, often at "event caches." After three decades of working in high-tech, it's nice to hang with people who can converse about something other than Windows vs Linux.
That about sums it up for me. The events are probably one of the most enjoyable parts of geocaching. There certainly is a diverse bunch of cacher out there!
Nobody's trying to sell you anything.
Except Premium Meberships:-)
What self respecting gizmo-nerd WOULDN'T be in to geocaching???
I run a Garmin Geko and a Navman PiN for my cahcing goodness
It's kind of an obsession.. be prepared to have large chunks of your spare time taken up with chasing tupperware....
He was Uber scary in real life though.
He came to my Promary School when I was a kid (*we were the nearest school to a certain chocolate factory who he used to promote)....
Very scary to a 6yo...... like Einstein on biker speed!
Ahh... memories...

What has the GPL got to do with Apache? It isn't released under it IIRC
I for one am skeptical about the intention of MS's move, and will watch with interest.

90%+ of all Supervisory/SCADA systems run on Windows, sorry to shoot you down.
The controllers may run proprietary O/S'es but nearly all the overarching architecture above the controller layer is Windows based.
I've yet to see a widely used CURRENT saftey management system or SCADA/Hybrid DCS system that isn't running on a Windows platform.
There's still older systems out there, but a lot of then now run under emulation under Windows as the hardware gets rarer.
(I work for a resonably big vendor in this field)
