Fighting Invasive Fish With Forks and Knives 180

Posted by samzenpus

An anonymous reader writes NPR commentator Bonny Wolf has a unique solution to battle the threat of invasive fish species in our waterways. She proposes we fight them with a knife, fork, and a few lemon wedges. From the article: "Take the northern snakehead, which has made its way into tributaries of the Chesapeake Bay. It competes with native species for food, and then eats the native species, not to mention the odd frog or bird, with its mouthful of sharp teeth. It's been called "Fishzilla." It breeds fast, has no natural predators and can grow to be 4 feet long. The northern snakehead hangs out in grassy shallows, making it hard to catch. But a couple of years ago, Maryland started promoting the snakehead as an eating fish. Its harvest has increased from zero to 5,000 pounds a year."

While I'm not a fan of the system, what you are paying for is mostly the motion tracking system. I do have the first generation dev kit and it's rather nice compared to similar prior systems (Virtual-IO for example). But it is also majorly over hyped and Facebooks involvement was a death blow for me. But that's just me...

ASICs generally aren't flexible enough that you could simply emulate another controller in firmware, while FPGAs suck too much power to use on commodity network adapters. Writing a new driver (or bringing an existing neglected driver up to scratch) is going to be quicker than trying to make hardware that's compatible enough to work with a driver written for another vendor's controller.

(Besides which, as that other driver is probably maintained by your competitor, do you really think they're going to make an effort to ensure that their later updates are compatible with your clone controller? You'll still have to maintain your own fork.)

I have often wondered why there isn't a vendor-neutral register-level standard for Ethernet controllers, along the lines of AHCI and xHCI. There is the virtio networking standard, but as it's designed for VMs I assume it does not cover Ethernet link management. I seem to remember that VMware tried to promote a common interface for SR-IOV virtual functions at one time, but that didn't get very far. Again that would not have included link management.

It's inherent in how they work. Rather then trying to secure them, which I don't think can be done, just start assuming they are insecure and treat them as such. Don't hold a private, personal conversation in a crowded public room and don't send text messages you don't want other people to see.

Slashdot Asks: Should Schooling Be Year-Round? 421

Posted by timothy

Around the world, American schools' long summer break is viewed as an anomaly, and the long summer seems to be getting shorter. While most American primary and secondary schools used to start after Labor Day, more and more of them now open sometime in August (and that's not counting the ones that have gone to a year-round schedule). Some of my younger relatives started a new school year last week (in Indiana), while Baltimore schools start later this month. Both Seattle and Portland's kids have until after Labor Day (with start dates of the 3rd and 4th of September, respectively). The 4th is also the start date for students in New York City's public schools, the country's largest district. Colleges more often start in September, but some get a jump start in August, especially with required seminars or orientation programs for new students. Whether you're in school, out of school, or back in school by proxy (packing lunches or paying tuition), what time does (or did) your school-year start? Would you prefer that your local public schools run all year round, if they're of the long-summer variety? (And conversely, if your local schools give short shrift to summer, whether that's in the U.S. or anywhere else, do you think that's a good idea?)

Perhaps I'm not understanding... but as my PayPal and eBay accounts have different passwords and i have two factor authentication setup using a DigiPass 5 rotating cypher key, I am unable to replicate what is being reported. No mater what, I am prompted for my DigiPass token key and password.

Maybe not Detroit, but definitely not in Northern California - it's way too expensive to do business there. For an R&D/Skunkworks style office, perhaps drawing on the local talent is worth the cost, but putting general office workers and blue collar labor there is silly when you have nice states like Texas, Alabama, North Carolina, and Michigan which have friendly labor laws and cheaper labor pools, along with some top minds in places like Austin, Huntsville, Raleigh, and Ann Arbor.
