unfortunately all the HMI software of the day seems to be for windows: citect, wonderware, etc.

I'm keeping an eye on http://www.inductiveautomation.com/ to see how their product does as it is built from open source libraries.

Additionally, you need windows to program protection relays ( http://www.selinc.com/ ) or your excitation system or your OPC server. You can't get away from windows in the industrial control and automation world.

I need windows to program the PLCs as well.

What I do is run linux and have a separate VM image for each program I need, one for GE multilin software, one for SEL software, one for each brand of PLC programming software.

Loading all the different shit I need onto a single install of windows means when that install gets fucked, as they all eventually do, I have to spend days reloading all the software and going through licensing bullshit.

Running the software in a VM means I can load it up, make the image read only so it is the same every time I boot, and then I'm set.

I have major issues with the automation and control world and the current state of the software it depends on, I think there is loads of room for a new player who understands software in 2010 and isn't burdened with a legacy product.

and for all the people talking about air gaps, I don't think they are as common as you think and as other commenters suggest are easily bridged by USB sticks.

Science

Your Feces Is a Wonderland of Viruses 211

sciencehabit writes "Thanks to an anlaysis of fecal samples from four sets of Missouri-born female identical twins and their mothers, researchers have concluded that human guts harbor viruses as unique as the people they inhabit; the viral lineup differs even between identical twins. Even more surprising? These viruses may be doing good work inside of us."

Any thermal plant like coal, oil, nuclear has restrictions on how fast the mechanical power into the generator can be changed.

Modern Hydro electric facilities can go from cold star to 100% output in 10 minutes usually, or from the usual minimum of 10% output to 100% on the order of a minute.

natural gas can also change output relatively quickly.

You can't produce power that isn't used, every second of every day every watt of energy that is generated is used somehow.

KDE

Sneak Preview For Coming KDE SC 4.5 249

omlx writes "KDE SC 4.5 is in feature freeze right now. Therefore, I decided to share some early screenshots with you. In general there are no major changes; it's all about polishing and fixing bugs. There are a lot of under-the-hood changes in libs, which as end users we cannot see. KDE SC will be released in August 2010." Note: you can also try out a beta of the release now, if you'd like.

Comment Re:Mikrotik a possible choice? (Score 1) 178

mikrotik is cheap, and flexible, and can do lots of things, but there are lots of advanced features that only work half way, half the time, or are half-way documented.

if you are going to keep it simple, or don't mind spending hours reading old forum threads then it might be the way to go!

Bandwidth does keep getting cheaper, but mobile bandwidth is different.

There is a finite amount of spectrum that is suitable for mobile, and it has a fixed capacity dictated by the Shannon limit.

The only way to increase mobile bandwidth is to increase the density of the base stations or the amount of spectrum used whereas increasing bandwidth to a fixed location is simply a matter of more wires/fiber.
