NASA is sending new and bigger spaceships to Mars, which means they need bigger supersonic parachutes. So big, in fact, that they don’t fit in any wind tunnel anymore, so their engineers had to find new ways to test them. New crazy ways. Really crazy. In fact, it’s the craziest test they got so far.
Would you know Reddit or Twitter if you were only looking at their layouts? You might not think so—but you’d be surprised how well you know the structure of your most-used sites. Now, you can take a test to find out.

Kaboom. And fireball. And ground shake. And shockwave. And boom. AtomCentral shows us some amazingly clear HD footage restored from 1953 of the Atomic Cannon test from Upshot-Knothole Grable. In the video below, you can see cars, jeeps, buses and tanks against the backdrop of the ginormous blast’s initial burst and shockwave. The blast eventually swallows everything.

Do you have suspicions that your ISP may be throttling (a.k.a. traffic shaping) some of your Internet traffic? It’s easy to tell if your ISP is blocking something, such as BitTorrent traffic, since nothing will get through, but it is more difficult to tell whether they are just restricting your download/upload speeds. That’s where the free Glasnost service comes into play.
Glasnost is a Java-powered web service that lets you run various tests for checking whether your P2P, email, or web traffic is being throttled by your ISP. Here’s a quick list of the 9 different tests you can run as well as a brief description of what gets tested with each of them:
I use Comcast for my ISP and I was happy to see that the couple tests I ran all came back saying that my traffic wasn’t being throttled. Of course this isn’t a definitive answer as to whether it is actually being done since they may only do it at specific times (e.g. during peak traffic periods), but it is a little more reassuring.

Meet 007. Not Bond but the bird. But they might just be as smart as one another because the crow can use tools to figure out complex puzzles just as well as a spy. Here’s a crow taking one of the most complex tests for the animal mind ever created. If he succeeds, the BBC says it’ll be a world’s first. Spoiler: he figures it out.

A few months ago we got our first look at the Spark-Renault SRT_01E Formula E teams will be racing next year, and just recently, that car hit a test track in France for the first time to see how it held up. Spark Racing president Frédéric Vasseur reported things went well, with the car turning about 40 laps over two days of testing at La Ferté Gaucher without taking a sip of fuel. The video after the break captures a few clips from the laps — running on a smaller 50kW battery, just 25 percent of the 270hp-equivalent power race-ready cars will have — and while we’ll need to adjust to the lack of noise, perhaps its impressive torque and handling can make up for it. More tests are planned before the first race in Beijing next September as the team pushes its mileage up bit by bit before running a full race simulation.

There are some great tools out there for testing a website’s performance including Web Page Test, Stella, and WatchMouse. Those are the three that I regularly find myself using, but the website monitoring service Pingdom recently updated their Full Page Test tool blowing many others out of the water.
The new interface they have is beautifully designed, which helps in understanding the data they are presenting to you. When you begin navigating through the various sections you’ll find a full waterfall view that lets you know how long each individual request on the site took, and you can even see a page analysis to help serve as an overview of all those requests.
Then you can flip over to the performance grade to get an idea of which areas on your site could use the most improvement. Expanding any of the sections will list out the requests that go against that particular rule, and towards the bottom they provide a link referencing what you can do to resolve the issues.
There are also some settings you can choose from before you initiate a test. One setting lets you decide whether the results of the test should be saved and made public, and the other is the location of the server running the test (Netherlands, New York, or Texas).

If you’re a web developer there is a good chance that you’ve had to mess around with a lot of CSS code. It’s not the easiest thing in the world to work with, but there are tools out there that try to guide you along the way. CSSDesk.com doesn’t provide any direct guidance, but it can help you quickly test out CSS expressions to see if they are doing what you expect them to be without constantly having to reload a page to have your change take effect.
You probably wouldn’t want to do an entire website design using CSSDesk, but it is great for fine-tuning individual objects. Things like buttons, boxes, and small sections of sites would definitely be the ideal uses of CSSDesk. There also isn’t anything on the site to distract you from what you’re working on, which means no ads and no unnecessary buttons or links. It’s just you and your code.
The other cool thing is that in a single click you can generate a URL that you can use to share the code with someone else. If you need help with your CSS code that feature could be extremely useful since there isn’t the hassle involved of having to create an account to share the code.

A lot of reviews for browsers reference a lot of performance and standards compatibility tests, such as the SunSpider or Acid3 tests. There is another test available to help you figure out how well your browser supports HTML5 already. The site is HTML5Test.com and scores the browser out of a possible 450 points.
The problem is that the HTML5 specifications hasn’t been finalized and so browser makers don’t have a full set of standards to work off of yet. Many of them are already working hard at incorporating many of the special elements for audio, video, forms, geolocation, WebGL, storage, and more.
My screenshot above is from the four major Windows browsers, and Chrome takes the cake with a score of 328 while Internet Explorer is lagging behind (duh) with a score of 141. It’s exciting to see Chrome so far out in the lead because that means other browsers like Opera and Firefox will definitely push hard to catch up.

Wondering why the BBC brought iPlayer downloads to just 11 Android devices, several months after iOS users got their turn? The broadcaster has just explained itself through a blog post detailing the Android app’s testing process. Like Netflix, the BBC had to focus its support on a handful of Android products in order to launch on time; this supports what we’ve heard from our own sources, who suggest that iPlayer development is normally arduous. To address as much hardware as possible on a tight schedule, the network conducted frequent, iterative tests that guaranteed compatibility relatively quickly. While the end result still leaves a lot of viewers without downloads, the BBC suggests that its testing process introduced the feature sooner than would have otherwise been possible. Whether or not you’re happy with the finished product, you can check out the corporation’s full methodology at the source link.
