Comment I'll try my best to stay away "from China" (Score 1) 460

Of course, personally, I would not buy tech products such as telecom equipment sold from China. And I said FROM China. There are plenty of American made products but sold from China on Ebay, for example. My fear is that they can be altered not just on the software level but also hardware. They killed my dog with the dog food I fed him. Now they are going to try to poison our kids. If you make everyone dumber, you'll end up more intelligent than the rest. That, folks, is what I think they are trying to do next.

The Perfect Way To Slice a Pizza 282

iamapizza writes "New Scientist reports on the quest of two math boffins for the perfect way to slice a pizza. It's an interesting and in-depth article; 'The problem that bothered them was this. Suppose the harried waiter cuts the pizza off-center, but with all the edge-to-edge cuts crossing at a single point, and with the same angle between adjacent cuts. The off-center cuts mean the slices will not all be the same size, so if two people take turns to take neighboring slices, will they get equal shares by the time they have gone right round the pizza — and if not, who will get more?' This is useful, of course, if you're familiar with the concept of 'sharing' a pizza."

Fusion-io IoXtreme's Consumer-Class PCIe SSD — Impressive Throughput 110

MojoKid writes "When Fusion-io's first ioDrive product hit the market, it was claimed to be a 'disruptive technology' by some industry analysts, with the potential to set the storage industry on its ear. Of course the first version of the ioDrive was an enterprise-class product that showed the significant potential of PCI Express direct-attached SSD storage, but its cost was such that the mainstream market couldn't possibly justify it, no matter what the upside performance looked like. Then we heard of Fusion-io's more consumer-targeted play, the ioXtreme, that was announced this past summer. Fusion-io has only very recently released these new, lower cost cards to market. The first-ever full performance review of the product over at HotHardware shows the half-height PCI Express X4 cards are capable of a robust 800MB/sec read bandwidth and about 300MB/sec of write bandwidth. The cards particularly excel versus a standard SSD at random read/write requests and even perform relatively well with small block transfers."

Submission + - uninterruptible power supply

moogoogaipan writes: We have about 200 desktops in our company. We do have a generator that will take about 2-3 seconds to start when the main power goes out. Well, that 2 seconds is the problem. Our desktops will turn off. Booting up takes a while for these desktops. I am actually more concern about the problems coming from having desktops shutting down unexpectedly such as power supply problems, RAM, etc... What do you think is the best option for UPS ? Right now, I am thinking purchasing 50 small UPS (2-3 computers can plug into one UPS just to stay alive within that 2-3 seconds of down time). Is it worth the money($10-$20K) to purchase a large UPS to support the whole department? Thanks for your inputs.

Comment Could IPv6 be a playground for virus/trojans ? (Score 1) 102

I love the idea of having more IP addresses but I fear the dangers of exposing our systems to the public net. NAT provides, at least, some sort of firewall for me. Sure, IPv6 can do NAT too but if I don't need it, why configure it? Just plug my PC into the public network and you're online with a public IPv6. Yeah, and that's what I think can be scary.

Submission + - Disaster recovery

moogoogaipan writes: After a few days thinking about the quickest way to bring my website back to the internet users, I am still stuck at DNS. From experience, even if I set the TTL for my DNS zone file as low as 5 mins, there are still DNS servers out there won't update until a few days later(yeah you, AOL). Here is my situation. Say, I have my web servers and database servers at a remote backup location. They are ready to serve. So my question for ./ers is that if we get hit by an earthquake at our main location, what can I do in a few hours to get everyone to go to our backup location?
