6) Finally your output chain should just allow everything:

# Accept everything: iptables -P OUTPUT ACCEPT

Now this is just plain shitty advice.

Thanks for the four links to external articles, though. Hopefully people will use them as a starting point rather than your own rules when deciding on their firewall configuration.

Best OSS CFD Package For High School Physics? 105

Posted by timothy from the why-not-stop-at-algebra-I? dept.
RobHart writes "I am teaching a 'physics of flight' unit to grade 11 Physics students. Part of the unit will have the students running tests on several aerofoils in a wind tunnel. I also want to expose them to a Computational Fluid Dynamics package which will allow them to contrast experimental results with those produced by the CFD package. There are a number of open source CFDs available (Windows- or Linux-based are both fine), but I don't have much time to evaluate which are the simplest to use in terms of setting up the mesh, initial conditions, etc. — a very important issue as students do not have much time in this unit." Can anyone offer insight about ease of use for programs in this niche?

Comment Not everyone wants more pixels, but better aspect (Score 4, Interesting) 952

Frankly for most people the existing 'HDTV' resolution has more than enough pixels, to get full benefit from increased number of pixels you would need a larger screen and sit closer to it. As it is, reading text on these high DPI screens is hard enough, and I often find myself increasing the default font size. This issue is particularly pronounced in laptop screens.

What I do want is more vertical resolution. The 16:9 craze means today we buy displays that are physcially larger and have more pixels overall than ten years ago, yet do not provide any more area for vertical display. You still have to scroll down far too much. It would be nice if someone still made decent, affordable 4:3 displays; a 1600 X 1200 in 21" format is going to be a killer!

Google analytics won't seem to slow down your website as long as you add it to the very bottom of your page, just before closing the html tag. The page and content will load quickly, even though the analytics might take another second the user doesn't care since everything else is alreasy visible on the screen.

How Do You Evaluate a Data Center? 211

Posted by ScuttleMonkey from the check-for-major-fault-lines dept.
mpapet writes to ask about the ins and outs of datacenter evaluation. Beyond the simpler questions of physical access control, connectivity, and power redundancy/capacity and SLA review, what other questions are important to ask when evaluating a data center? What data centers have people been happy with? What horror stories have people lived through with those that didn't make the cut?

Why Doesn't Exercise Lead To Weight Loss? 978

Posted by timothy from the that-would-be-too-easy dept.
antdude writes "The New York Times' Well blog reports that 'for some time, researchers have been finding that people who exercise don't necessarily lose weight.' A study published online in September 2009 in The British Journal of Sports Medicine was the latest to report apparently disappointing slimming results. In the study, 58 obese people completed 12 weeks of supervised aerobic training without changing their diets. The group lost an average of a little more than seven pounds, and many lost barely half that. How can that be?"

These problems can happen with any company's product these days: Microsoft, Apple or even the open source OS like Linux or Freebsd. There are so many configurations to test that it is difficult to gurantee that the updates will work flaswlessly across the board.

It is nice that this issue can be fixed by users themselves without having to send the computers for repair.
