Comment Why gravity is treated as a force? (Score 1) 97 97

Why do physicists insist on treating gravity as a force? Since Einstein, we know gravity is the curvature of space-time. It may be represented as a force in calculations but in reality there is no force.

If gravity is not a force then do we really have a hierarchy problem? For eg. shouldn't Newton's constant, G, be some kind of average curvature of space-time between two bodies and be calculable from this curvature?

Obviously, if this is the case, G has nothing to do with Fermi's constant and we should not compare the two.

Submission + - Slashdot BETA Discussion-> 60 60

mugnyte writes: With Slashdot's recent restyled "BETA" slowly rolled to most users, there's been a lot of griping about the changes. This is nothing new, as past style changes have had similar effects. However, this pass there are significant usability changes: A narrower read pane, limited moderation filtering, and several color/size/font adjustments. BETA implies not yet complete, so taking that cue — please list your specific, detailed opinoins, one per comment, and let's use the best part of slashdot (the moderation system) to raise the attention to these. Change can be jarring, but let's focus on the true usability differences with the new style.

Submission + - Slashdot forces a beta site by default

kelk1 writes: As a poor submitter found out (https://developers.slashdot.org/story/14/02/05/2328224/html5-app-for-panasonic-tvs-rejected---jquery-is-a-hack), Slashdot (https://slashdot.org) suddenly forced a preview of its beta site without any warning on all its viewers.

Judging by the comments, the feedback was immediate and clearly negative.

I cannot speak for the forum moderation side, but my reaction to the front page was an knee jerk: "Oh no!, not another portal full of noise I cannot speed-read through." Text and hyperlinks are what we need, please, and as little graphics as possible. Think lynx, thank you.

Submission + - Kim Jong Un, Ghost of Hitler, Announce Approval of Slashdot Beta

An anonymous reader writes: The Supreme Leader of the Democratic People's Republic of Korea and the ghost of the former leader of National Socialist German Workers' Party have approved of the new Slashdot Beta site in a rare instance of agreement amongst the two. The two strong personalities have a history strong disagreement of the most mundane of things but united today outside the Great Pyongyang Unicorn Lair with Slashdot Editor Samzenpus to show support. "Morale at Dice [Slashdot's parent company] is at an all time low, but the show of support from such great world leaders is an encouragement to the entire team", said Samzenpus.

Comment cmpxchg8b (Score 1, Informative) 148 148

I haven't tried this with the latest version by even a version 4.x GCC cannot generate inline code with the 8 bytes version of cmpxchg with 32bit code. Doing this in a function is OK.

I think the problem is that this instruction almost takes up all of the registers and GCC cannot cope with this if you want to do it inline.

cmpxchg8b is useful for lock-free code.

Comment Slavery (Score 0, Troll) 518 518

Everyone should have total control over his/her body. If you are not at liberty to sell your organs that means you do not have total control.

If you do not have total control that means you are a slave. You are a property of the state.

In short, I totally agree with the article since I am against slavery.

Comment Re:Time travel is not possible without (Score 1) 465 465

There was a short story about this (I can't remember the title). The story was about travelling back to Jesus's time to verify Jesus's existence but the travelers found themselves in space as Earth was elsewhere.

They had to travel ~220 million years back since that's the time the Solar system takes a turn around the galaxy's core and the Earth position would be the same when they started their travel.
