I don't get to spend 2/3 of my day at the office, when I'm at work I need to access email/web to get equipment specifications or manuals on the road. I try to get my laptop loaded with the required documents. If I miss critical info I have to either spend alot of time trying to get it over the phone or I can find a internet connection(which is near impossible in half the locations).
AT&T really has the power to make or break the iPhone. If the network doesn't support fast enough connections to enable fast safari apps the device is sunk. But I like the articles brief coverage of the other non-issues that the iPhone haters are using.
Seems like MS wants in on Apples game. Make hardware companies pay to have their drivers offically MS approved. Also keep people from using older, obsolete computers. In order to get that next version of windows you'll need a new rig with all the 'taxes' paid up.
Well I dealt with the emergency HVAC automation for this place, at least the software for the equipment. As it was explained to me they have two 1000 ton ice tanks to provide cooling to the data center for 20 minutes while the gensets come online after a power failure. The ice tanks are preferred because you don't want to run electric chillers on batteries. But the abnormal thing is that they just large holes cut into the tanks and water is run straight through to draw the heat off into the ice.
Normally cooling through ice tanks is done through glycol coils, much like a heat exchanger. The glycol is used for the transfer medium due to its lower freeze point. Standard use of ice tanks for cooling building is for reducing electrical demand during peak periods. It seems the load is so high that there is no danger of providing the air handler loop too cold water.
A 1000 tank could carry the cooling load on a multistory building for an hour or two, I've never seen a building that could expend two 1000 ton tanks in 20 minutes.
The thing I've noticed about industrial automation is that the programming software is typically made so that electrical engineers can write and maintain the code/logic. They have no training in computer security. Also if there is any disconnect between the customers and the programmers(term used loosely), such that the customers were not the ones writing the original sequence of operation or the logic wasn't written by the company that installed the system and does owner training, the security situation can be very dire.
I can't count the number of times I got requests to make a control system web accessable just so the 'janitor' could check that one temperature that he thought was the endall to keeping his process running.
For a industry that has a lot of promise it sure has a lot of growing up to do.
I want one of these companies to release a complete implemetation for hardware virtual machines. I want my Windows games to run full bore, right next to my linux dev environment.
Maybe I'll just have to wait another 5 years for Xen to come of age.
I setup a backup system using DAR and SATA hard drives, since they are a fairly cheap backup medium. I wanted hotplug, really just hotswap so I could take out the full drive and put in an empty one. The commands I found after searching went along the lines of:
It has to be watched through dmesg, sometimes the drive migrates from/dev/sdX to the next unused letter. The other thing I noticed is that the drive has to be online while booting up to be available, it wouldn't find a new drive. It has been a while since I set the system up so I should upgrade to find out if this still applies.
I can't imagine that you have actually priced out a 'vendor' system. They are anything but low priced. After being quoted 20 grand for a 15-20 phone system and being told that support costs will be outragous, you would do exactly what my boss did.
Keep the ancient system that was fried by lighting. God knows the PC tech will keep the system limping along 15 years past its due date.
One problem I can't solve, once the junk mail is moved to the junk folder I want that message marked "as read". I would rather not see a new mail notification in my task tray unless it is an important message.
It would also cut down on training the program since it would mark the message "as read" and junk with one click.
Advantech makes a few lines of touchscreen integrated computers. One of the things Ive seen is the TPC line of industrial grade computers isn't as robust as the PPC line (the one mentioned in the parent post).
The touchscreens are the same but the intenal componets are not. I've had many TPCs with failed hard drives or bad motherboards.
Yes. Its definitly possible, and in my case preferred. I crushed my wrist many moons ago and typing on a normal keyboard for extended times really hurts.
I have the touchstream LP and its very easy on that wrist. No pressure/force is needed by the fingers which in turn keeps the stress down my wrist. (you can only guess what other activities are prohibited by this "handicap")
I wouldn't recommend this thing for anybody impatient, even after 6 months with it I still can't touchtype very fast. It also makes some standard key combos (alt-f4) a bit difficult. And forget gaming with it - the repeat rate isn't high enough to allow it. The mouse emulation isn't good enough for it either.
I do know that running Power Quest drive image over a tcp/ip connection that multicast stopped our network cold. Everything on a 100Mb network stopped until a gig image completed.
