I’m still running it on all of my machines here and it has been great – I really don’t notice it at all. It just sits in the background and according to the logs is saving between ~20% & ~60% power consumption by my various CPUs. And that’s just what it should do.

Miserware have just (18th Jan 2010) started a new trial programme to celebrate the introduction of the first Beta of the power saving software for that [ahem] other OS, Windows. The trial itself and entry into a competition to win iPod Nanos or Asus PCs is open from today and the Micromiser software is available for: Vista, Windows 7, Windows XP, Debian 4.0, 5.0, unstable, Fedora 8, 9, 10, 11, RHEL 4.7, 5.3, SLES 10 and Ubuntu 7.04, 8.04, 8.10, 9.04, 9.10.

If you want to try it out and join in the trial and competition just follow this link to sign up.

Note: Do please note that (on Linux at least – am not sure about Windows as I don’t use it) there is a script you should run after installation called mw-feedback. It sends back textual information about your hardware. This is a plain text file of mine for Lobsang so you can see what it contains. The purpose is so they can identify any hardware issues with the beta software and also verify the widest range of solutions for which the product is suitable.

From the Fedora Mailing List:

I have now changed the default panel configuration in F12 to include gnote instead of tomboy, and changed comps to make gnote default and tomboy optional.

This won’t replace tomboy in existing installations, but new installations will get gnote instead of tomboy.

This also means that gnote should show up on the live cd (where we excluded tomboy previously, due to no space for mono).

And further on the Wiki we see:

Gnote is installed by default in GNOME for this release replacing Tomboy. Gnote is a port of Tomboy from Mono to C++ and consumes less resources. Gnote is both an applet that can sit in your GNOME panel as well as a individual application you can run within other desktop environments. Fedora Desktop Live CD excluded Mono in the last releases due to lack of space. Gnote will be installed by default in the Live CD as well in this release. Tomboy is still available as a optional alternative.

This is the right thing to do IMHO. I have no problem with Mono being available in the repos for those who wish to use it. I would however much prefer that it is not installed by default on my distribution of choice.

Roy also posted a good article this morning explaining some of the key issues which make Mono such a bitter pill for many. If you care about what software you use, it is well worth reading.

Also, if you want to know how to remove Mono from your Ubuntu distribution:

• Hardy Heron
• Intrepid Ibex
• Jaunty Jackalope

When I’m travelling around London (as I did quite a bit this week) I tend to take my 10″ webbook netbook device as it is lightweight and easy to cart around. For comms, I have a 3G dongle that gives me Internet access from virtually anywhere. [Ask Daviey just how handy that was the other day ]

Now, this is by no means a scientific result and I haven’t had time to actually do a proper comparison with and without the Miserware code, but I reckon I’m getting around 30mins more life from the battery since running the Micromiser software. Before installing the code I was getting between an hour to an hour and a half or so of battery life, so I guess that that would equate to an average improvement of around a third.

Those 3G devices get really hot after being on for an hour! They make a really nice hand warmer in the winter though My lappy is running Ubuntu 9.04 desktop.

The Beta trial is still active and running and Miserware are very happy to have more subscribers sign-up. So If you would like an invite, leave a comment here and I’ll get on it asap.

One point that came up from a couple of people who were interested in taking part in the trial was to do with some restrictions on what you could say publicly about your observations. I am happy to say that Miserware have updated the license to be a little clearer and allow for more information disclosure. Here’s the text of the mail (with obfuscated email address) I received regarding the changes:

Dear MicroMiser beta participant,

Thank you for your involvement in the MicroMiser beta! The response so far has been tremendous and well beyond our expectations. The information we are getting when you run the mw-feedback script is really helping us improve our products and documentation.

The license you agreed to when registering for the beta said you needed permission from MiserWare to publish data reported by our software. We would like to lift this requirement to some extent by allowing you to share performance and power numbers reported by MicroMiser. More precisely our lawyers told us to say it like this:

“You are hereby authorized to disclose information regarding the performance of the MicroMiser software, provided that such information is provided to you in a MicroMiser software report.”

This includes any information (including energy savings information) provided by MicroMiser in any of its log files and/or information reported in tools such as the mw-feedback script which reports system specific information to MiserWare thereby aiding future development and earning you points in the incentive program.

Several folks have asked about benchmarking against other power management software. With regard to benchmarking, we want to clarify the intent of the license. Our intent was not to preclude benchmarking altogether, but to ensure the measurement methodology is fair to all parties. More precisely, our lawyers told us to paste both permissions together:

“You are hereby authorized to disclose information regarding the performance of the MicroMiser software, (i) provided that such information is provided to you in a MicroMiser software report, or (ii) provided that such information is obtained using techniques approved in writing by MiserWare.”

There is no need for you to sign another license agreement as these clarifications simply give you additional permissions under the original license.

These clarifications are the result of your feedback. Please continue to send your comments to f–db–k at miserware dot com . We promise to keep listening.

Regards,

MiserWare

So, if you want to help these guys with their Beta, and get on the incentive program too (I’ve just won and received a really cool green iPod Nano) simply leave me a short comment below.

MiserWare MicroMiser is an intelligent software power management solution for x86 servers, laptops, and PCs running Linux. MicroMiser automatically optimizes a system to use energy more efficiently without compromising performance or availability. The MicroMiser Power Management Daemon (see below) when installed on a server, laptop, or PC, matches the energy consumed by the system to the load on the system automatically. MicroMiser typically lowers total system energy use by 10-35% even when a system is 100% utilized. MicroMiser also tracks the energy saved for use in estimating cost savings and carbon emission reductions.

I have installed it on 4 PCs so far and all seems to be fine. Installation is very simple as the download is in a deb or rpm package.

I am especially interested to monitor any battery-life performance improvements on my laptop computers and any savings to my always-on–home-server will be most appreciated. The site has downloads for most of the recent Ubuntu, Debian, Fedora, RHEL, and SLES distributions.

It appears to work on VIA C7 chips, and Intel Core2 8X00 and mobile T5000 series. Well, it does for me.

As you can see above, the company claim between 10 and 35% power savings with this software which is definately not to be sneezed at in these frugal times.

If you would like to take part in the beta, leave a comment below (I need your email address, which is not shown if you just fill in the comment form boxes) and I will endeavour to get you an invite.

Glyn Moody has covered most of the bases in his usual eloquent style.

I’m in complete agreement with Glyn here. This is a really big deal. Perhaps not today or tomorrow, but it is making a HUGE statement to the business community at large that there are credible alternatives to M$, and, with IBM’s help they can choose from Novell, Red Hat or Canonical for their desktop IT.

Of course, we [ the enlightened ones ] have known this for sometime. But the dark-grey-suit brigade didn’t really have a clue. They simply believed what they were told.

Now they are being told something new.
