Dipping capacitors and batteries in nanotubes could improve capacity

Super capacitorsStanford researchers figured out that, by dipping electrodes for super capacitors in a solution of carbon nanotubes or a conductive polymer they could increase the charging capacity by up to 45-percent. The team started working with composite electrodes of graphene and manganese oxide, since manganese is cheap and plentiful, but were hamstrung by its low conductivity. The thin coating of more conductive material greatly boosted the capacitance of the electrodes, and thus their ability to hold a charge. Further tests are still required to find the actual energy density of the dipped electrodes, but lead researchers Yi Cui and Zhenan Bao are already working on a way to apply the same technique to batteries.

How to Stop Google, Yahoo & Bing from Tracking Your Clicks

This article was written on October 21, 2009 by CyberNet.

In 2008, Google said there’s no such thing as complete privacy. You’re being tracked all over the web by their AdSense ads, by sites that use Google Analytics and – probably the most important – their search engine. But Google Search isn’t the only search engine that tracks your behavior. Concerned about your privacy? In this article, we’ll show you how you can get rid of click tracking in search engines.

The secret redirect

Google

google tracking-2.png

Whenever you click a link in Google Search, your click is redirected through a secret URL. If the site you’re going to is http://www.cybernetnews.com/, Google will do a secret redirect through a URL that looks similar to http://www.google.com/url?url=http://www.cybernetnews.com/. In some cases, you can reveal the secret redirect by right-clicking on a linked search result. If that doesn’t work, your last resort is an HTTP sniffer.

There are several Firefox add-ons that claim to get rid of Google Search’s click tracking. CustomizeGoogle is one of them. Among other tweaks, it promises to remove click tracking and disable Google Analytics cookies. If you just want the anti-tracking feature without the bells and whistles, there’s a Greasemonkey script you can download called Google Tracking B-Gone. To use Greasemonkey scripts, you need to install the Greasemonkey add-on for Firefox. Also, if you use an international version of Google such as google.co.uk, you have to change the script’s URL range from http://*.google.com/* to http://*.google.*/* to ensure that the script is allowed to operate on your local Google site.

Yahoo

yahoo tracking-1.png

Unlike Google’s redirect, the one Yahoo uses is always easy to find. Right-click on a link and look at your status bar to reveal an intimidating garglemesh of strange characters originating from rds.yahoo.com. You can get rid of that by installing this Greasemonkey script. However, my HTTP sniffer revealed that Yahoo does some additional click tracking from a URL that starts with http://search.yahoo.com/ra/click?. To disable this, add http://search.yahoo.com/ra/click?* as a filter to Adblock Plus.

Bing

bing tracking.png

Bing seems to have a very subtle click tracking mechanism. The only fishy thing Bing does is call some URL’s that start with http://www.bing.com/fd/ls/ whenever you click a search result. Again, Adblock Plus can help you deal with this if you add http://www.bing.com/fd/ls/* to its filter list. Turning off JavaScript on bing.com seems to help too.

Shutting off the HTTP referrer

Although the tips listed above can help you stop search engines from tracking your clicks, it does not keep websites from gathering information about your web search. This is done through the HTTP referrer. Any page on the web can retrieve information on how you stumbled upon it, i.e. which URL referred to their web page.

The referrer is also known to be used by site owners to retrieve information about the search engine you used and what your search query was. On rare occasions, some sites alter themselves if you found them through web search. For example, I’ve seen sites display “Welcome, Googler!”-esque messages and even sites that highlight your Google search terms on the page you landed on. Although this rather creepy practice is not widespread, it just shows how much a site really knows about you.

Fortunately, you can disable the sending of the HTTP referrer to the websites you visit. While it is possible to disable the HTTP referrer entirely in Firefox’s about:config, this can break certain functionality on some sites. There’s a Firefox add-on called RefControl that does away with this issue by allowing you to add exceptions for sites that need the referrer.

Other browsers

It is possible to use the Google Tracking B-Gone and Yahoo Click-Tracking Disabler scripts in other browsers. So if you’re really serious about extending your tinfoil hat protection to other browsers, you can check out these resources:

To disable the HTTP referrer, follow these instructions:

Since I’ve only tested this with Firefox, I cannot guarantee that the content from these resources is accurate.

Robot uses semantic search to get a Subway sandwich, do Jared’s evil bidding (video)

Old PR2 can already fold towels, play pool and grab an ice cold beer — really, the Willow Garage robot is just one task of short of mastering the day-to-day activities of your average college student. What’s that? It can get a sandwich, too? Never mind. And this isn’t just any “get me a sandwich” command — the stout white ‘bot uses semantic search to infer possible locations for sandwich, using knowledge of similar objects and environmental models. In the below video, you’ll see PR2 make its way to a refrigerator, in search of sustenance, only to come up empty-clawed. Undaunted, it hops on an elevator and makes its way to a Subway sandwich shop. The joint project from the University of Tokyo and University of Munich was recently shown off at recent robotics conference. No word on when PR2 will be programmed to hold the onions.

Grid10 review

Grid10 review

Second chances aren’t always easy to come by, and when Fusion Garage disappeared off the map following the unabashed failure of the JooJoo tablet, we certainly didn’t expect those doors would be opening again. But open they did, swinging wide as the company treated itself to a product launch of the sort usually reserved for big-named companies with big-named devices.

This time it’s the Grid10 tablet, a $299, 16GB, 10.1-inch slate that plays nice with Android while simultaneously thumbing its nose at the OS Google built, instead relying on the completely custom-built GridOS. This new challenger can run Android apps despite not actually running Android itself, purporting to give users another, better choice of armament in these tablet wars. Is it truly better, or is it just different? The answer is waiting for you just after the break.

Snap to Window

This article was written on April 15, 2008 by CyberNet.

You might remember the freeware application Pitaschio that we covered last year which includes a “snap to windows” feature that I really love. Basically how it works is when you’re dragging a window around the screen it detects when you’re near another window based on a tolerance you specify. It would then snap the two windows together so that they line up perfectly.

There’s another freeware utility called allSnap that does something similar, but has a lot more options geared towards that one particular feature. You can set a toggle key that will disable the “snap to window,” and there are a variety of different items you can have windows snap to:

allSnap

Being able to snap windows to each other is either a feature you’ll either love or hate. For some people it will be annoying, but others will enjoy being able to cleanly organize multiple windows on the desktop.

This is a Windows-only application, and there is also a 64-bit version available for testing. It does require a brief installation before being able to use it.

Remembering Steve Jobs: we all pay tribute

As news has of the passing of Steve Jobs spread tonight, people have started showing up at Apple’s stores to pay tribute to its co-founder and former leader. We stopped by the 5th Avenue, NYC store and found this scene with many gathering to pay tribute through their thoughts, words and pictures. Outside there’s signs and flowers, downstairs the store is packed. Apple headquarters featured a bouquet covered bench, adorned with homemade signs, and an iPad. In downtown San Francisco, people lit candles and placed post-in notes on the Apple store’s windows. The images we’ve captured are in the galleries below, if you have something to share of your own then contact us via our tips form so we can include it here.

Sean Buckley, Darren Murph, Zach Honig and Myriam Joire contributed to this report.

Microsoft Thanks Windows Live Hotmail Testers with Beta Badges

This article was written on May 02, 2007 by CyberNet.

If any of you were beta testers for Windows Live Hotmail, did you get your gift yesterday? I’m not writing this for the sake of it being news, but more for the sake of how cheesy it actually is. I think they meant well, but a Beta Badge? Maybe I’m under-estimating the power of a badge. The subject was “A Big Thank-you” and when I opened it up, it said “It’s our launch party but you get the presents!” Below is what the offers were:

Betabadge

When I saw the “Great Windows Vista Offer” I thought that maybe they were offering a coupon, which would have nice gesture from Microsoft. Maybe $25 or $50 off the purchase of Vista? However, the offer was only good for $100 off a Gateway computer with Vista Ultimate on it, or 4 free accessories with the purchase of a custom built PC.

Beta Badges aside, this must mean that Windows Live Hotmail will be making its way out of beta soon.

CyberNotes: Fast, Easy, & Fun Photo Editing

This article was written on June 10, 2008 by CyberNet.

CyberNotes
Time Saving Tuesday

arrow Windows Windows only arrow
When it comes to photo editors there is definitely no shortage of them available. It’s almost a guarantee that a Windows user can find a freeware application that will do all the things they want, and more. Some prime examples are Paint.NET, PhotoFilter, and the feature-rich Photoscape. Today we’ve got another one that we would like to add to our favorites: Photo! Editor.

What makes this application so special? Aside from being freeware it offers a lot of features that are often too complex for casual users, and presents them in a way that most people will understand. You can do all of the common tasks such as rotate images and remove red eye, but there are also several features you won’t find in most standard image editing applications.

Once you get the program fired up you should see something like this:

(Click to Enlarge)

–Click…Done!–

Photo! Editor doesn’t want to confuse you with settings that you won’t understand, and for that reason it has several auto-correct features that take only a single click. This includes removing the red eye, enhancing the colors, and removing noise (despeckling). You’ll find all of these options located on the main toolbar.

For those of you that want a little more control over the settings you can click the arrow located next to each of those buttons. Then you will be able to configure the details for each of those settings, and tweak them until you’re little heart is content. Each time you try to manually configure a setting it will provide “instant help” along the right side of the screen. That way you won’t have any troubles trying to figure out how a feature works.

I do want to say that the feature for removing the noise actually works well. Below is a portion of a photo that I took several years ago with a 1MP camera, and because of the lighting there was some significant noise. Take a close look at the left portion (unedited), and then look at the right half (with denoise applied). The program significantly improved the photo by smoothing everything out.

–Make Up (Remove Blemishes)–

How many times have you wanted to touchup a photo before, but thought it was too much work? This photo editor has what’s commonly referred to as a healing brush, and it can remove blemishes from just about anything with very little effort on your behalf. To demonstrate this feature I snagged a photo of a car that had some rust on it, and gave myself 30 seconds to try and improve it using the healing brush in the program. Here are the before and after shots:

healing brush.jpg

It’s obviously not perfect, but you also have to consider how large the areas were that I was trying to fix. In most cases the healing brush will be used to repair tiny blemishes on faces, and so this example is a little bit overkill. Oh, and there is even a special healing brush it includes that can be used to whiten teeth in a photo. ;)

–Straighten Images–

Imagine that you just snapped an awesome photo of the sunset, but realized when you got home that you didn’t have the camera level with the horizon. What program would you use to rotate the image so that the horizon is beautifully level? Can’t think of one? Well, you can use Photo! Editor now.

In this app all it takes to straighten a photo is drawing a line that goes along the horizon. It will then take that information and straighten the image accordingly.

–Caricature (Have Some Fun!!)–

I found this image of an adorable dog, and I just couldn’t hold myself back from using it with the Caricature feature. How this works is you open a photo with the Caricature setting, and then start warping it. Here’s what my initial screen looked like:

caricature settings.jpg
(Click to Enlarge)

I played with the photo for less than a minute, and all I used was a simple click and drag technique. After I was done I think it’s safe to say that the dog looked a little more interesting than it did before:

caricature.jpg
(Click to Enlarge)

I think this is actually my favorite feature of the entire application, and the best part is that it’s so easy to use. Go ahead, open up some photos of your friends and go to town! You know you want to. :)

P.S. You are 100% liable for any relationships destroyed with friends and family due to embarrassing photos created using this feature.

–Overview–

If you do decide to give this app a try I’m sure you will see why it’s so great. It’s very straightforward, and has all kinds of features I haven’t found in traditional photo editing applications before. Let us know what you think, and be sure to post links in the comments to some of the caricatures you make. :D
