Re: [Hampshire] Linux printer recommendations.
I hate all printers - they are the only piece of technology that has not gotten significantly better in 5 years - however I recently HAD to buy a printer and was shocked at how easy the Kodak ESP 7250 was to get workign in linux - it literally was 30 seconds - I was gobsmacked. -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

Re: [Hampshire] Linux power monitoring tools.
I agree with Bob. This generally isn't possible with normal pc hardware. Also, unloading a module doesn't necessarily stop the hardware using power.

Oh and Kelly wrote the interface so users can get graphs against time and other parameters such as temperature. Standard PC hardware doesn't normally allow you to monitor the current drawn from a supply, only the voltage, hence no way to determine the power consumption. Voltage was easy to measure so was thrown in to keep customers amused, but current would have cost a few pennies so wasn't. A few specialist suppliers and high end manufacturers do include current monitoring hardware. Look for ESA compatible power supplies for example. I cannot seem to find any tools that monitor things like: 1) Total power consumbed as a monotonic kWh value. Unless you've got one of those expensive monitorable power supplies your best bet is going to be a CurrentCost appliance monitor or similar. 2) Power broken down by device within the system. Without the sensors to measure it software is only going to be able to give you the broadest stroke estimate. Again per device current sensors is rather specialist. 3) Power broken down by process within the system. Even with hardware sensors ascribing power consumption to individual processes would be difficult. I guess you could look at a processes I/O stats then do something like 10% of disk I/O equals 10% of disk hardware power consumption. I think a lot of the monitoring software out there is smoke and mirrors on top of guesswork. -- Bob Dunlop -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk -- -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

Thanks Freaky. They tried to sell me one of those in Comet but after Kodak took too long to take digital photography seriously I have kept away from their digital products. I am interested to hear your experience of this printer. The printer is mainly for my wife to use from 'Win 7' and a friend of hers recommended an Epson SX425W so I bought one. I had trouble at first getting it to work from Ubuntu 10.04 as the correct driver was not listed in the Printer Setup. However after I downloaded one from [1] it now works. It is too early to say how well as this was late last night. [1] http://avasys.jp/eng/linux_driver/ I expect Lisi could use this without the /eng/ part?
