you want some cycling practice but you're worried about all of the reckless drivers out there. You don't want to resort to one of those lame stationary bikes, either. The solution? Free motion bicycle rollers. Updated: More danger!
I would love to bike more often, but the thought of cycling here in New York City is utterly daunting. This alternative, however, seems even more terrifying.
If you want to brave your unfinished basement on two wheels, a free motion set up only costs about $35 in parts and can be assembled by following this Instructable. Just don't say I didn't warn you. [Make and Instructables]
This is pretty cool and dangerous !
The new Sapphire Radeon HD 5970—based upon the acclaimed ATI HD 5970 chipset—is the new world's fastest graphics card. Its 3DMark Vantage score is an insane 22,000.
The overclocked ATI GPU runs at 850MHz, which is supported by 4GB of DDR3 RAM (itself, clocked at 1,200MHz). And all this hardware necessitates three fans an a massive heatsink, making it thicker than your average video card. Outputs include two dual-link DVIs and one mini DisplayPort. Weird that there's no HDMI on here, like the 5870 has.
AMD expects that we'll see the HD 5970 from a variety of different manufactures, which is good because while we have no idea what the thing costs, it won't be cheap.
THIS THING IS POWERFUL AND AMAZING!!!
You're probably relatively confident in your various machines' integrity against hackers. Repeat Pwn2Own hacking competition victor Charlie Miller would like you to know that you're wrong.
In an interview with OneITSecurity, Miller picks off questions about hacking and security with just enough ease and nonchalance to make me queasy. Like, you know how Mac OS exploits are supposed to be tougher to root out than Windows exploits? Not quite! And they're both vulnerable:
Windows 7 is slightly more difficult because it has full ASLR (address space layout randomization) and a smaller attack surface (for example, no Java or Flash by default). Windows used to be much harder because it had full ASLR and DEP (data execution prevention). But recently, a talk at Black Hat DC showed how to get around these protections in a browser in Windows.
And obviously, Linux is fortress, right? Again:
No, Linux is no harder, in fact probably easier, although some of this is dependent on the particular flavor of Linux you're talking about. The organizers don't choose to use Linux because not that many people use it on the desktop. The other thing is, the vulnerabilities are in the browsers, and mostly, the same browsers that run on Linux, run on Windows.
And within a given operating system, surely you can ensure immunity from exploits by choosing a secure browser like Firefox. Surely. No? GUUUGHHH.
[The safest browser is] Chrome or IE8 on Windows 7 with no Flash installed. There probably isn't enough difference between the browsers to get worked up about. The main thing is not to install Flash!
So the guy who consistently prevails Pwn2Own, a competition where hackers demonstrate exploits for sport, says that Flash, which is installed on about 98% of computers on the internet, unifies all browsers in insecurity. The slightly better news is, despite inherent insecurities that he doesn't bother to elaborate on, mobile smartphone platforms are relatively secure as compared to their desktop counterparts. So there's that.
The full interview is definitely worth a read, even for the tech disinclined—it's a good reminder that you (and you!) can never completely avoid online security threats. So, stay on your toes, and look out for... something? [OneITSecurity viaCrunchgear]
During the Winter Olympics, we've seen more than our share of athletic action sequences—complex motions broken into stills. For this week's Shooting Challenge, you'll be recreating the effect in the real world (or anywhere else you like).
Shoot an action sequence of any sort.
You'll want to set your camera on a tripod and shoot in burst mode with a minimum of 3-5FPS. Then you'll combine these images in photo editing software.
1. Submissions need to be your own.
2. Photos need to be taken the week of the contest. (No portfolio linking or it spoils the "challenge" part.)
3. Explain, briefly, the equipment, settings and technique used to snag the shot.
4. Email submissions to contests@gizmodo.com.
5. Include 800px wide image AND 2560x1600 sized in email. (The 800px image is the one judged, so feel free to crop/alter the image for wallpaper-sized dimensions.)
Send your best entries by Sunday, February 28th at 11PM Eastern to contests@gizmodo.com with "Action Sequence" in the subject line. Save your files as JPGs or GIFs, and use a FirstnameLastnameAction.jpg (800px) and FirstnameLastnameActionWALLPAPER.jpg (2560px) naming conventions. Include your shooting summary (camera, lens, ISO, etc) in the body of the email.
High School students have sued the Lower Merion School District in Philadelphia for spying on them using their laptops' built-in cameras. School administrator activated the webcams remotely and recorded students' activities at home. Way to go, KGB-wannabe assclowns. Updated
The situation was discovered by the Robbins, when their kid was disciplined for "improper behavior in his home." How could that be possible? The Vice Principal showed a photo as the evidence. A photo taken with the school-provided laptop webcam.
That school is so weird. Why violate laws like that? They are just dumb thinking they were never going to get caught or something.
I don't want to be receiving any photos of your bruises after you fall flat on your face 2ft up the side of your garage, but this is how Stansfield cobbled together his "Spiderman gloves," which he's used to climb up to 120ft previously.

The military currently trains its soldiers using PCs, but they were interested in switching to the Xbox 360 for a number of reasons. Unfortunately, Microsoft was not too interested in helping them out.
According to Danger Room, Microsoft refused to sell consoles to Roger Smith, chief technology officer for PEO STRI, the Army command responsible for purchasing training equipment. Why wouldn't Microsoft sell them consoles? Well, according to Smith, three reasons:
* Microsoft was afraid that the military would buy up lots of Xbox 360s, but would buy only one game for each of them, so MS wouldn't make much money off of the games.
* that a big military purchase would create a shortage of Xbox 360s.
* that if the Xbox became an Army training device, it would taint its reputation. Microsoft was concerned that "do we want the Xbox 360 to be seen as having the flavor of a weapon? Do we want Mom and Dad knowing that their kid is buying the same game console as the military trains the SEALs and Rangers on?" Smith told me during an interview for Training & Simulation Journal.
Microsoft are the greediest people ever in my opinion. They don't want to sell it to them because they will only buy about thousands of the same game. That is so dumb.
