RockMelt,BlackSheep,Firesheep

What is RockMelt? Do We Need a Facebook Web Browser?

Yes, there’s a new web browser designed around the idea that you can share more, and share more quickly on Facebook and Twitter. That alone may turn some people away, depending on how much they value their privacy. However, after trying it for a short time, I can see how this browser could easily turn normal Facebook users into hyped up Uber-Facebook users.
RockMelt was founded by Eric Vishria and Tim Howes, and is backed by Netscape developer  Marc Andreessen.  It was released yesterday, mostly by invitation only. You can get a copy of this browser by visiting RockMelt.com and signing up via your Facebook ID.
After signing up late last night I received my invite and downloaded it. The install went fairly quick and here’s the first thing I saw … a Facebook login.
rockmelt-login
Yes, that’s right, it seems to be required. However, that makes sense.
It took me quite awhile to figure out most of the actions I could perform. If you open the “RockMelt” menu at the top right corner of the browser, and click the “Help” item, you’ll find help for a few basic tasks. Here’s the first thing you see there.

As some of you have already noticed, RockMelt is built on top of Chromium, which is the basis for Google’s Chrome web browser. Those using Chrome now won’t have a hard time getting around in the browser.
Rather than go into too many details, I’ll show you the  RockMelt video preview. It’s very well done.

Techie Buzz Verdict:
I tried it, I like it, and haven’t found any major bugs yet. If you are already using Google Chrome, and you’re in Facebook often, there’s no reason not to give RockMelt a try. You don’t have to make it your default browser, and it won’t do anything to your current web browsers.  Farmville works very well in Chrome and RockMelt.

BlackSheep Thwarts Firesheep Intruders

Firesheep, a  for snooping on  and  logins on open Wi-Fi connections caused quite a storm when it was released. It went on to show how insecure your computer could be.
BlackSheep Firesheep Protector
The exploit could snoop on unprotected Wi-Fi connections and retrieve login cookies for Twitter and Facebook, which could then be used to login to a users account and access their data. If you are using an open Wi-Fi connection, the first thing to do is to to secure your Wi-Fi connection. If you need help with it, read our earlier guides Wi-Fi Demystified I and Wi-Fi Demystified II.
BlackSheep is another  which is designed to combat Firesheep. BlackSheep drops fake session ID information on the wire and then monitors traffic to see if it has been hijacked. If BlackSheep finds that someone is snooping on you, it will display an alert as seen in the image above.
If you have a secure Wi-Fi connection, you have nothing to worry about, but if you don’t, the threat of Wi-Fi snooping by Firesheep is pretty high. You can circumnavigate the threat by using https instead of http while accessing the websites, but to be on the safer side, install the BlackSheep add-on too, which can be downloadedfrom here.

Top Extensions for Opera 11

 has always been a browser with a small (as compared to  or ) but devoted following that keeps increasing with each iteration of their browser. While their simple mobile version of the browser (Opera Mini) is vastly popular – they never saw a similar growth in the desktop market. The folks at Opera Inc. thought it was probably due to the unavailability of Extensions for their browser, and so they added the extensibility of extensions in Opera 11.
So without further ado, here’s a look at the top extensions for Opera 11.
NoAds
NoAds: NoAds is a NoScript + AdBlock extension. In the words of its creator NoAds = (NoScript + AdBlock)/2. It blocks 99% of scripts on a site that originate from a different domain, blocks text ads and you can even import subscriptions from AdBlock as well as EHH! No more ads.
FastestTube - YouTube Video Downloader
FastestTube: This simple and sweet extension just adds a drop-down menu on any YouTube video page where you can download the video that is playing in many formats. There are some minor problems with the integration with Redirect to HTTPS videos, but that should be fixed shortly.
Reddited
Reddited: Are you an avid Redditor? Do you scramble up to submit a page to Reddit only to find that it’s already been linked to? Do you hang your head in defeat and rage at the trolls that are laughing at you? Then this is the extension for you. All it does is tell you if the page you’re looking at has been reddited or not. If it has been submitted, it shows you the comment count on the link as well.
Translate Extension
Translate: If you’re one of those anime fans without a drop of Japanese within you, or if you’re the newshound who has to go to various foreign-language sites for news then this extension will do you a world of good. Translate auto-magically detects the language of the page you’re currently working on and will offer to translate the entire page for you. Built on top of Google Translate framework, the translation, although slightly grammatically off, works and works well.
Opera Mini Simulator
Opera Mini Simulator: This one is for the web developers. The add-on loads your focused tab as how it would look under the Opera Mini environment. Though a little slow when simulating, the add-on is quite useful for mobile developers.
GMail [iOS mode]
Gmail [iOS Mode]: Don’t want to wait for the Gmail page to open when all you need is to know if you have unread mail or not? Enter the Gmail [iOS Mode] extension that changes the UserAgent of Opera to an iOS device’s. So you can use the slick and lean Gmail interface on your desktop browser itself!
Do you have any favorite Opera Extensions? Do feel free to share them with me through your comments.

The Physics Behind Ball Design

Each sport is governed by different sets of rules, and those that use balls each have different specifications for their equipment. The baseball, basketball, golf ball and football are all essentially by-products of physics. Sports is big business, and hundreds of millions of dollars may hang in the balance when we are dealing with a few obscure physical laws. For example, at the recent World Cup soccer championship, the shape of the pieces making up the surface of the soccer ball was changed by the manufacturer, leading to charges that some teams received an edge over others.
Lots of sports equipment designers and even the franchises themselves have consulted with my colleagues to gain a better insight into the science of the game. You may be wondering why the sports industry would want to pick the brain of a physicist; well, let's take baseball for example. We all know that when you look at a baseball, it has threading woven through the leather of the ball in a particular shape. The threads of each section meet at the seam of the opposite thread on the other side of the cut. Tests, including time-lapse photography and wind-tunnel technology, have allowed us to determine that these threads play a huge role in the success of the fastball, curveball and even the famed knuckleball. Basically it boils down to: The faster a ball spins as it slices through the atmosphere, the more stable it is from point A to B. Since a fastball spins very rapidly for example, it is very stable and this is widely due to the layout of the threading.
But let's take a look at the knuckleball, which has been the topic of many a debate over the years. The movement on this pitch is caused by mini-vortices forming over the threaded/stitched seams which cause the ball to rapidly change it's position in the air. The ball can change direction, corkscrew, appear to take a dive, flutter, dance or even curve in two opposite directions during it's flight. The key to the knuckleball is the way that the pitcher holds the ball with his knuckles, releasing it straight out to completely avoid the normal rotational spin of a pitch. The immediate absence of the rotational spin causes an asymmetric drag that tends to deflect the trajectory towards the side of the stitches. This drag is essentially what gives the flight of the ball such an erratic motion on it's way to the catcher's mitt. This particular pitch is also very difficult to catch and some knuckleball pitchers have even required their own catchers.The art of a knuckleball:
Have you ever wondered exactly what's inside of a baseball?
Now also, if you take a look at football. It's true that the faster you throw your spiral, the better control you have over the delivery. The faster the spin, the greater reduction of eddy currents allowing it to slice through the atmosphere to deliver a touchdown. The mini-dimples on golf balls are also engineered to reduce eddy currents, allowing the ball to travel much further by reducing the drag on the ball as it flies through the air.
In 2006, a group of researchers at Arizona State University used a bit of aircraft science to try and design a better golf ball, which would be more efficient in all weather conditions, cost less and travel farther. One of the battery of tests they performed took 64 high-powered computers running for a full week to evaluate the flight of one ball under one set of conditions.
 So, this just gives you an idea of the thought and ingenuity that goes into the designs of such equipment. Think about all of that the next time you throw a baseball, football or swing the golf club to hit that dimple-covered golf ball.
So, this just gives you an idea of the thought and ingenuity that goes into the designs of such equipment.

You might even find that a little physics will give you an advantage over the competition.

Each Top 10 entrant is linked to the page where Firefox users can install them from. See if you can't find something new for your browsing routine below.

10. AutoCopy

We like it because we're bloggers, having to quote and copy links and code every day, but anyone who does a fair amount of copying to and from the web will dig AutoCopy. The basic use: It copies anyt text you select on the web as soon as you select it—no Ctrl+C necessary. For pasting into text forms, you simply hit the middle mouse button rather than Control+V. If that's all it did, hey, we'd recommend it to anyone who writes, copies, or pastes a lot, but we also have to point out that it fixes really long, wrap-broken URLs automatically. Three cheers for fewer pinky-finger stretches!

9. Google Gears

It's a bit more technical than most browser extensions, but for all intents and purposes, Gears is an easy-to-install add-on that unlocks an entirely new world to the internet. Primarily, it takes Google apps offline—Gmail, Google Reader, Docs, and Calendar—but a handful of other apps make good use of its mini-database powers, including Remember the Milk and PassPack. Still, given the kind of impressive implementation Offline Gmail received, we've only scratched the surface of the potential in them there gears.

8. Personal Menu

Personal Menu is kind of a next-generation version of themuch-loved Tiny Menu, accomplishing the same basic but totally great effect: Giving the web content you're actually looking at more space to breath. It does this by stripping the screen-wide menu bar at the top of Firefox's windows and converting it into a single drop-down menu, then lets you choose which of those menus show up in it. Keyboard shortcut ninjas can enable an option to temporarily bring back the menu bar when Alt is pressed, and the extension auto-adds a history and bookmarks button to the main toolbar to compensate for the two most active menus.

7. Better Gmail 2

It's not a revelation that Gmail functionality is one of our pet obsessions. Better Gmail 2 fixes or answers a lot of our Gmail complaints and wishes in one neat package. You can individually enable or kill any of Better Gmail's more than a dozen fixes and improvements, and whenever a great new Gmail user script hits the Greasemonkey realm, you can count on seeing it added to Better Gmail by our own Gina Trapani.

6. DownThemAll!

Not a tool you need every day, but really useful when you want it, DownThemAll is a selective, powerful download manager. It makes short work of snatching all the images on a page (including those links to the "bigger" or "zoom" versions), all the MP3s off a music blog, or any other kind of filter you can set up. Gina's showed us how to do some smart tune-grabbing and Flickr downloading with her guide to supercharging your Firefox downloads with DownThemAll, but her walkthrough should work for any types of files and any page. Incidentally, DownThemAll isn't just one of our favorites—it's also the most popular download manager among Lifehacker readers.

5. Tab Mix Plus

Remember browsing before tabs? We kind of recall a faint smell of kerosene and words like "dubloon" still in use. In all seriousness, browser tabs are the key ingredient to how many of us multi-task on the web every day, and Tab Mix Plus is a master key for everything you like or loathe about tabs. It controls which links open in a new tab, new window, or same window to an OCD-friendly level, adds key features like italicizing the text on tabs you haven't viewed yet, and super-powers Firefox's undo closed tab feature. It gets way, way more intricate than that, but even for just the bare basics, it's totally worth the install.

4. Automatic Save Folder

This one is technically an experimental, non-Mozilla-approved download, but with the positive reaction it received in our experimental extensions round-up, and experimental extensions no longer requiring a sign-up and log-in, it's more than worth stepping out on the ledge. It's the smart-downloading companion to DownThemAll, placing the files you download in a certain folder on your system based on the file extension or the site you grab it from. So if you always want the .xls spreadsheets you grab from Gmail to go into your Reports folder, but an .xls you grab from anywhere else to show up on your Desktop like everything else, you set the rules. JPG files from your friends' Flickr page, versus photo downloads off the rest of the net? Tell them where they should go. It keeps your folders and desktop clean, and sets up rules you shouldn't have to tweak much after one go—truly an extension after our own geeky hearts.

3. Adblock Plus

You knew this would be here, didn't you? Ad-blocking can make the internet a more tolerable place to look around, and AdBlock Plus does this with a powerful ad-blocking feed subscription you can pick at start-up. Alternately, any ads you find particularly distracting ("ONE RULE TO A FLAT STOMACH: OBEY") can be right-clicked on and killed in perpetuity with "Adblock Image." Ads can be brought back if you're feeling curious, but as many a commenter (and AdBlock-loving editor) has said: After getting used to AdBlock Plus, you forget what the internet truly looks like until you turn this extension off. Lifehacker is, of course, an advertising-supported site, so we'd love it if you kept our ads displaying, opting instead to individually kill only the ones that make your eyeballs itch.

2. Greasemonkey

For Firefox changes that require deep browser integration (like adding a new button to the browser's chrome), there are extensions. For everything else, there's Greasemonkey. Greasemonkey is a difficult extension for the uninitiated to wrap their heads around, but once they do, it's a breeze. In essence, Greasemonkey is a meta-extension of sorts. It does nothing by default when first installed; the power lies in Greasemonkey user scripts developed by JavaScript-wielding geeks fed up with under-performing sites or interested in bringing more power to the sites they already love. If you don't like seeing labels on your Gmail messages, but wouldn't mind seeing them when your pointer hovers over them, there's a fix. Want YouTube to acknowledge your bandwidth and load high-quality clips by default? Same deal. Those are just a few recent examples, but the list goes on, and the fixes keep getting better. You can find Greasemonkey scripts all over the web, but if you're just getting started, you may also want to check out Userscripts.org—sort of like Mozilla's add-ons site but for Greasemonkey scripts.

1. Foxmarks/Xmarks

Foxmarks is gradually rebranding as Xmarks, but what we really like about Fox/Xmarks remains the same as the last time it claimed the Must-Have crown: It's nearly seamless at keeping your bookmarks and passwords synchronized between browsers on any platform, and stores them on a site you can visit from any browser where you can't install an extension. If you're not down with the cloud, you can even tell this extension to store your stuff on your own server. Foxmarks is also available on IE and Safari, and you can separate your work bookmarking from ooh-cool life stuff with selective bookmark profiles. It's the tool that lets you keep fleeting thoughts, IM links, and other ephemeral web stuff all together, so of course we dig on it. The transition to Xmarks adds a few semi-nifty, social-y features to your searching and bookmarking, but if you're not keen on those changes, you can easily disable them in the Xmarks preferences.
