You just had to order them from Europe. Kind of a pain, but they're quality routers. Hopefully at the end of this trial we wont have to circumvent the system though in order to get our "grubby hands" on some quality, dd-wrt running hardware.
Any chance you guys could release the map creator for SCII prior the release of the game? I'd love to go into SCII with custom maps (Read: dota) ready to be played, and I think a lot of us who play custom maps more than the melee game would agree.
O'Reilly News recently interviewed Arjan
van de Ven about his efforts to improve Linux performance and reduce power
consumption. Arjan works for Intel in the Open
Source Technology Center. This interview is approximately 30 minutes.
One of the projects you're probably most known for in the past
couple of years is the PowerTOP utility, which I
found very fascinating. Looking at some of the gains you've made over the past
18 months, it seems like Linux-based devices are saving a lot more power than
they used to. What do you consider the big successes in the past year and a
half?
To be honest we fixed effectively the entire Linux desktop space. It's
not--PowerTOP is more--it's not just what we fixed with PowerTOP is not
individual pieces. We fixed everything. For me that was a success.
Is that everything in terms of not just desktop but servers as
well?
Yeah; we fixed not just Evolution. We fixed Firefox; the thing with
Firefox was that it wasn't one thing that was broken. Everything had problems
and we had to fix all of it. So for me the success was how quickly everything
got fixed; it was just amazing.
In this context you consider
fixed--everything is no longer broken in the same way or--?
Everything is no longer keeping the CPU out of idle basically.
Do you have a reference machine? I guess I'm asking what's your
benchmark for this, a particular software configuration stack or particular
type of machine, or are you willing to say it's pretty much every Linux based
machine out there?
I'm looking at several machines--my own laptop but to be honest, what runs
on my own laptop is what I care about most. At least that's where I got more
battery life, this is where I see the changes. I tend to run a quite rich
environment on my laptop but I also look at service. We look at all kinds of
machines and we see the same trend everywhere in that all the various pieces of
it--never polling or keeping the CPU up. They all got fixed.
In fixing this, is there a component of education, for example,
saying "Instead of doing a busy wait on a select loop or continually polling
you should set a kernel timer and wait for that to call you"?
That's part of it but the biggest thing is that you had no visibility. Just
two days ago at IDF I spoke with a developer of the GNOME desktop and he said,
yeah; when I saw it happen I fixed it in 10 minutes, but you don't know it's
there until you see it from PowerTOP. Adding the visibility turns out to be
enough for people to start fixing it. They know how to fix--how to not poll
most of the time.
You can't fix something you can't measure.
If you don't see that it happens you don't know it happens and you can't fix
it.
Are you getting the same sort of results from other
projects you run into?
GNOME was there but it's almost everybody goes oh yeah; we should have not
done that; either they fix it themselves or some--a lot of people give them the
fix and in general it's like oh yeah; we shouldn't have done that. Unless you
see what's happening you don't know what to fix, so the biggest thing that
PowerTOP did was add visibility. We can see under the hood what's going on and
then we can fix it. And quite often the fix is very simple.
It sounds then, maybe I should be able to say that just about
everybody is happy to see this. Is that the case?
Yes; people--all the developers I've worked with--and that's quite a
few--they all go oh yeah. Thank you for the fix; we should have no problems in
the first place. We didn't know this; it's fixed now. In the beginning I did
most of the fixing when PowerTOP was very new and now days the people do it
themselves. The developers learn
I'm not sure how everyone else uses their computer but I only need to boot my Linux machine about once every 30-60 days.
Some people like to power down their computers to stop them from wasting energy at night.
How they sleep without the sweet, sweet sound of fans running though leaves me dumbstruck.
Not only is this an impressive accomplishment, but if this can be applied generically to most distributions then it should present an excellent opportunity for advertisement. Showing how you can boot, check your email, read the latest news, and be done with all you need to have done while a fellow Vista machine is still booting says a lot. Even if we can get most distributions down to 15sec average, it's a huge leap. Grats to these guys.
I think you got the wrong impression from the summary. They aren't selling a boxed version of Ubuntu that comes with the codecs pre-embeded in the OS - they're just offering those said codecs for download on their site.
The big thing here is not that they're offering them for sale, but that they're streamlining the process of the sale. The codecs have always been available for sale through fluendo's store, canonical is just making the process of sale slightly easier. The only thing I'm concerned about is that users will get the wrong message. New convertees to ubuntu (and there are a lot of them) might think that this whole "linux is free" thing is just a scam. Time will tell.
Shuttleworth paying out of pocket to help the ubuntu experience is nothing new. He's always done this. The printed CD's of ubuntu have always been free to whomever requested them. That's cost out of pocket for canonical. Don't get me wrong, this is great; but it's something they've always been doing.
Providing this level of internet infrastructure will be a viable investment for the future. Realistically this level of investment will keep them ahead of the pack for the next 10 years and during that time it will open the doors for businesses that typically operated on sneaker net to operate online. Faster transfer speeds mean more business gets done. More business means a better economy, which through taxes will easily recoup this initial loss.
I've had too many poor experiences with other hardware vendors to even consider not going with newegg. I hate to not really give you an answer you're looking for, but trust me on this one. After ordering from a few other peeps online you'll go back to newegg. Everyone goes to it for a reason.
I suppose this is yet another reason why it's nice that a few email services (most notably gmail) allow you to append a string to your email address using the + symbol (e.g. youremail+string@gmail.com will go to the inbox of youremail@gmail.com). In effect it allows you to "salt" your email, which adds a layer of complexity when trying to match these hashes with valid email (not to mention it allows you to check which site compromised your email if you use different 'salts' for each site you use your address on). If more email services start to allow this (doubtful), more sites start realizing that a + in your email is still a valid email (more doubtful), and more users start using it effectively (even more doubtful still), then I don't think the MicroID will be a huge problem.
No offense, but this just seems like an elaborate waste of money. We've seen immersion pc's before ( http://www.youtube.com/watch?v=M80eUcUVrmw ). Other than a fancy case and a waterfall, what makes this any different? Why is it worth £100,000 versus a fishbowl PC that'll set you back $200? Give us some decent benchmark results at least; as of now though, I see nothing really original other than a cool case mod here.
To be quite honest though, those who are professionals at digital manipulation would never save their work as.jpg before they are finished. From personal experience, if I need to flatten the image and save it, I'll go for a lossless.png format. However if you have any version of photoshop made within the last decade or so, you'll have a handy feature called "snapshots" built right into photoshop - which stores the state of the manipulation you are currently at, and you can revert to at any time. This almost entirely eliminates any need to save the file as a different format save for finishing.
Also though, to get around the deterioration of the.jpg is quite easy. Simply adding random noise to the image will throw off any algorithm trying to scan it for compression, while being nearly undetectable to the eyes. This is also a pretty common thing to do when doing professional manipulations, as it often will make it more believable if the noise across the photograph is uniform.
tl;dr - Those are only follies that someone who wasn't a professional would fall prey to. Any digital professional would bypass all of those simply due to how he went about doing his job.
I have my worries about this, and I have no doubt that we all do here on/.. What I definitely do not want to see is/. becoming another digg/reddit/delicious. On the other hand, hopefully slashdot will be able to mold the content more so that it doesn't just become a "HERE'S ANOTHER FUNNY CAPTION PIC FROM 4CHAN" fest. Don't get me wrong, those things have their place and are sometimes humorous, but it doesn't fit the niche that is/.. Remember, the slashdot tagline is "News for Nerds" - not "Funny Image of the Day for Nerds".
With any luck, it will hopefully become something more along the lines of Daily Wtf, which still provides insight while remaining humorous. And in any case, congrats on rolling out a new feature for us/. staff.
"...with our catalyst almost 100 percent of the current used for electrolysis goes into making oxygen and hydrogen."
If that is true (although I definitely have my doubts, as tales and empty promises of the past have made all of us highly skeptical when we read something like this), then it should open the road for a significantly more efficient means of producing hydrogen for hydrogen powered cars / devices. Hell a car equipped with a solar cell could just bake during the day to recharge itself and be ready to go for the commute home come 5pm. Though until I hear a confirmation of MIT's findings from another university/respected source, I hold on to my severe doubts about this.
I really don't understand China. They lock down the flow of information in their country so that they don't look bad, but in doing so generate a ton of negative media saying how they lock down their information. Could someone please explain what benefit this gives them?
The 60 watts is what the entire system is using. That includes the hard drive, the RAM, psu, mobo, etc etc.
They get the 4 watts from observing that when idle the system is at 56 watts, but when at a full load it meanders over to the 60.1 watt range.

a common thief finds a way to access the positions of all of these rich people. Seems to me an easy way to establish targets, not protect them.
