I’ve recently been testing some cool new software on Linux. It claims to be able to save more energy than the standard power saving utilities available on Linux, and in a way that doesn’t negatively impact system performance. The software is Linux-only right now, and runs on netbooks, laptops, desktops and servers. They have packages for Debian, Ubuntu, Fedora, Red Hat and SLES, all in 32-bit and 64-bit versions.
It’s now moved into an invite-only beta phase, and I’d like to invite more people to use it. I’ve already asked some friends if they’d like an invite, and sent one to those that want them. But I’m not going to send out invites to everyone I know without asking first, because I know some people might not be interested, and some don’t like their contact details being shared.
So I’m posting this to say if anyone would like an invite, just contact me with an email address I can send the invite to, and I’ll buzz one over, no obligation.
Once you get the invite and install the software, you can really help out by reporting back technical details about your system. They provide a little utility which sends information like your cpu & kernel version securely to their server. It clearly states what it’s sending before you send the data, so if you’re uncomfortable sending that data, you can choose not to.
Full disclosure: I’m not involved in the company itself other than being a friend of one employee, and a tester and happy user of the products. I get points for inviting people which might result in a prize. You will too if you join. You also get points for submitting the feedback, so make sure you do that!

If you have a laptop, could you notice that you could use your laptop longer when on battery? Did you measure (using acpi output) the power consumption of this tool and previously?
It would be interesting to have concrete figures. But this is an interesting feature!
Looking forward for a more detailed article.
They can do what they like
WTF, why don’t they release the code already?!
Can I have an invite please?
Drop me a mail with your email address..
The company is called Miserware.
Is it possible to get some more info? Further reading? Maybe even the name of the software or company?

It might be sent securely, but what does their code do on your box?
Is this open source code?
It scales your CPU frequency.
Not currently open source, maybe in the future it will be
Closed source software running only on Linux doing better than the existing open-source stuff? I’d rather trust the Intel guys to save my laptop’s energy
The package I installed replaced powernowd, which as far as I know, isn’t an Intel product.

for Phoronix just to have another thing to benchmark.
I like how OS X kick’s Ubuntu’s butt in 3d graphics performance benches. It gives me hope that our drivers will improve.
