Comment Use thermal energy for something useful, Helsinki (Score 2) 136

That's what is done in Helsinki. Actually data processing can be very economical and green. If the waste heat generated from process will be used for something useful.
As it's being done here: http://www.greendiary.com/entry/helsinki-data-centre-installed-in-cathedral-bomb-shelter-to-heat-500-homes/
It's just logical to use waste heat from any other sources (like industry processes) is being re-used in similar way.

Comment Opt for Vimeo? (Score 1) 69

I have lately opted for Vimeo. Google HD videos are sometimes really slow to load. I don't know why. Everything seems to be ok, but video just isn't loading as expected. With Vimeo I haven't had that problem ever. Vimeo image quality is also clearly superb. Content quality is also clearly better.

Comment Placing near window nope - Passive Repeateter (Score 1) 358

So? What's new? Our building got renewed about 6 years ago. At that point we found out exactly what they say. Cellphone signal was gone for two of the three operator available here. Reception was weak for the only available operator. Out at yard all operators gave full reception!

Reason? Thermal radiation insulation using very thin aluminium foil. It's not only in walls also windows are protected. Open window and placing phone just about 5 cm outside, full reception. Close window and place phone 5 cm inside, no reception at all. It's pretty clear situation.

Solution: Buying two mobile antennas and and about 20 cm of cable. Drill hole through the wall, Place another antenna outside, insert cable, place another antenna inside. That's it. Now you have passive pass through for the signal.

P.S. This solution works very well for cellars and basements too, if you want to have signal where it isn't normally available.

Comment IO issues (Score 1) 135

Fuse-NTFS-3G makes my system really crawl when there is USB-disk IO. UI and everything else is totally stalled for long periods. I'm not Linux guru, but I just confirm that I'm also expering IO issues even when system load should be pretty low. "Linux Bender 2.6.32-27-generic #49-Ubuntu SMP Thu Dec 2 00:51:09 UTC 2010 x86_64 GNU/Linux". I guess some tweaking might be required to fix this issue.

Comment Highly I/O latency dependant application (Score 1) 472

Just to mention a very bad app, I'll say Evolution. If there is any heavy disk I/O it becomes ultra sluggish. And you're asking for coffee break especially when you're changing from mail folder to another or deleting messages. I was practically forced to use ionice with any disk to maintain acceptable performance with Evolution. (2.6.32-25-generic #45-Ubuntu SMP x86_64 GNU/Linux / GNOME evolution 2.28.3)

Comment Re:SQLite database vacuum (Score 5, Informative) 341

There are a few alternatives to yet another plugin:
1) You can use standalone SQLite3 installation to open bases and vacuum those.
2) Use Python script for vacuuming.
3) You can use Error Console with following string to vacuum bases:
Components.classes["@mozilla.org/browser/nav-history-service;1"].getService(Components.interfaces.nsPIPlacesDatabase).DBConnection.executeSimpleSQL("VACUUM");
I personally prefer last option, beacuse no additional software is required.
