I wish there was a visual diff tool for function block programming in PLCs. I am moving more and more towards the "structured text" type PLC programming just so I can get a sensible change history.

Some siemens PLCs have a default superuser password hard coded in to the firmware. Siemens hasn't released an update to remove it. Control systems should be on separate networks, but even those networks are susceptible to wandering USB keys

what's the attraction to gold, other than being somewhat scarce and well prospected for (probably no massive surprise claims to be found). The value assigned to gold is clearly not due to its industrial applications. Gold for jewelry is al

60% was a plant factor, meaning that the 200 MW plant output will be 200 * .6 when averaged over the course of a year, presumably because some turbines will be down for maintenance some of the time, and the temperature difference will be le

750 million, payback in 11 years. for comparison, hydro electric costs about $2 million per megawatt so a 200MW hydro plant would be $400 million, but with associated environmental concerns.

all of the appliances are not on all the time, sometimes more power is used, sometimes less. 1.3 kw per hour for every hour in the year is the average.

unless you had a perfectly vertical mountain your tower would end up being longer and costing more. if you did have a perfectly vertical mountain it would still be somewhat difficult to build on the side of a cliff. I suppose you'd need a

have you ever been trying to fix a problem with half a dozen people staring over your shoulder? It doesn't help.

I think this was possible without siemens help. Many of Siemens customers would be familiar enough with the control system product in question to find weaknesses in it. People find flaws in software of all sorts without help from the vend

I develop control systems for power generation. Current trends are towards more and more automation, interconnectedness, collecting of business information and integration with smart grids. None of this should take place over the public i

They state in the last paragraph that Ubuntu+CentOS+Other Linux OS market share in the survey was 16% which puts it ahead of OSX but they chose to separate Other Linux out in the chart so visually it doesn't seem as significant. Maybe I'm u

I recall reading an article saying that the latest intel chips had 4-5 billion transistors, this article doesn`t have any transistor counts higher than 600 million. Something must be missing.

a nuclear power plant costs 6-8 billion up front, before you get a dime back and takes 2-8 years to build. Nobody in the US except the government will loan utilities the money to build or upgrade a nuclear power plant. I'm all for nuclear

The model arm wearing the watch was not a small arm, and the watch looked big. I don't know the size of a nano but it looked too big to be worn on the wrist to me. I do have fond memories of calculator watches though.
