Filed under: Digital Cameras Vision Research already has some pretty capable high-speed cameras under its belt, but the company looks to have outdone even itself with its latest model, which is apparently the first such camera to hit the one-million pictures-per-second mark. Of course, to grab that impressive burst of images you'll have to settle for a 256x8 resolution, although you'll still get a decent 6,315 pictures-per-second with the maximum 1280x800 resolution. Otherwise, you can expect 8GB, 16GB or 32GB of internal storage depending on the exact model (which includes both color and monochrome options), "unprecedented light sensitivity," and Vision's Extreme Dynamic Range feature, which'll let you capture two different exposures within one single frame. No word on a price, although some things are probably better left unsaid. [Via Gadget Lab ]   Read | Permalink | Email this | Comments Blogged with Flock

Filed under: Laptops We knew we were in for some rough chuckles when Birmingham, Alabama signed up to provide an OLPC XO to every K-8 student last December , but we didn't think they'd be this silly from the get-go: apparently the mayor's office, which negotiated the deal, is now saying the school board needs to add WiFi to every school for the laptops to work. That's news to us -- the mesh-networking XO was designed to be used in rural parts of the third world, after all -- but we're still puzzling out what mayoral advisors John Katopodis and Bob McKenna meant when they said they're "trying to make the whole city WiFi," or where they got a quote of $39 per school to enable wireless access. Of course, the only response from the school board was one member who worried about students accessing porn -- which seems to be a real theme with the XO -- but for some reason we're not at all surprised that bureaucratic officials have totally missed the point...

Here we show that perceived numerosity is susceptible to adaptation, along with primary visual properties of a scene like colour, contrast, size and speed. Apparent numerosity was decreased by adapting to large numbers of dots and increased by adapting to small numbers, the effect depended entirely on the numerosity of the adapter, not on contras...

http://precedings.nature.com/documents/1526/version/1 Open Data (OD) is an emerging term in the process of defining how scientific data may be published and re-used without price or permission barriers. Scientists generally see published data as belonging to the scientific community, but many publishers claim copyright over data and will not allow its re-use without permission. This is a major impediment to the progress of scholarship in the digital age. This article reviews the need for Open Data, shows examples of why Open Data are valuable and summarizes some early initiatives in formalizing the right of access to and re-use of scientific data.

Filed under: Misc. Gadgets Looks like Bug Labs is fixing to release its BUGbase in more than one version due to apparent issues related to solid, stable open source WiFi chipsets and drivers. Picking up the Hiro P Edition monicker (let's hope it doesn't snow crash), this revised first BUGbase will ship without 802.11, but adds a small joystick control, and as recompense for the wireless sacrifice, Hiro P owners will get a free BUGvonhippel module (the hardware breakout box, basically), and the option to snag a pluggable WiFi attachment on the cheap at a later time. For those who want to wait for the full, integrated-WiFi experience, Bug's not yet offering a set schedule for the "regular" base kit, but Hiro P goes on pre-sale at the Bug Labs store for the regular early adopter price this Monday.   Read | Permalink | Email this | Comments Blogged with Flock

With Leopard came Xgrid 2, with much improved performance and a few new features that many Xgrid users will probably find useful. Initially just one post, my article on Xgrid Leopard had grown too big, and I decided to split it into 2 posts, that are both available right now: Xgrid Leopard: the good, the bad, the ugly, and the new stuff Xgrid Leopard: Scoreboard rules! read more Blogged with Flock

New York based Drop.io launched a dead simple “drop box” for files last November. The service is online storage on the back end, with a very simple/clean user interface and upload features on the front end. It is similar to box.net and a number of other startups. Users can upload files via a Flash tool or by simply emailing files to a designated address. Files an also be uploaded via a widget (see example here in the right sidebar). The page itself ( example ) can be open or password protected. The pages can be anonymous, and each one, called a “drop,” has 100 MB of free storage (you can upgrade to 1 GB for $10/year). There are also RSS feeds and email alerts for drops, although they do not contain enclosures. You have to link through to get to the actual file. All in all, it’s a fairly generic service with a better-than-average but hardly revolutionary interface. Today, though, they added a very nice niche feature called, simply, Voice . Every drop page has a phone number and ext...

Filed under: Storage , Networking The number one complaint about the Drobo is pretty obvious: getting the damn thing on your network without using a host computer. Well, consider that complaint sorted. Today Data Robotics is releasing a NAS upgrade for Drobo called the DroboShare, which will support: Gigabit Ethernet (yes!), static or dynamic IPs Auto-mounting SMB shares via Drobo Dashboard (supports SMB authentication) Dual USB 2.0 ports for two Drobos per DroboShare EXT3 file system support (officially!) Capacities up to 16TB per Drobo (provided you feed it 4TB drives that won't be out until, say, 2010) And possibly our favorite: email alerts, should a drive happen to crash, for example It's also worth noting that Drobo is still capable of switching between NAS and direct-attached modes if you decide you want to take your Drobo OFF the network (but why would you do a thing like that?). The biggest problem with this add-on? It's $200, which brings...
