How many different sites are you browsing and keep going back to?
If it's a lot, bigger cache will help. but I doubt you have so many that you will reach a cache size that penalize the search in the cache.
Speed of your Internet tube is at stake also, of course, very high speed needs no cache from user point if view.

Submission + - After Negative User Response, ChromeOS To Re-Introduce Support For Ext{2,3,4}

NotInHere writes: Only three days after the large public has known about ChromeOS to disable ext2fs support for external drives, and linux users voiced many protests on websites like reddit, slashdot, or the issue tracker, the ChromeOS team now plans to support it again. To quote Ben Goodger's comment:"

Thanks for all of your feedback on this bug. We’ve heard you loud and clear.

We plan to re-enable ext2/3/4 support in Files.app immediately. It will come back, just like it was before, and we’re working to get it into the next stable channel release."

Yes, I don't buy his conspiracies and UFO beliefs, but since he is a leading authority on magnetohydrodynamics and mastered geometry I don't see him as any raving fool.
J.P. Petit is a knowledgeable scientist with independent views, now disregarded because of some of his foibles.

That's why I won't say that all of his theories or mere ideas should "be taken with much skepticism", that would be very unfair and at least irrational.

He could be right on this geometric approach, no matter what strange views he can have on other subjects.
Geometry is just his field and sometime science subjects need people from other fields to advance.
Moreover I've seen some other recent scientist publications with similar results, but with physic approach, I'll link here if I remember.

Submission + - Infected ATMs Give Away Millions Of Dollars Without Credit Cards

An anonymous reader writes: Kaspersky Lab performed a forensic investigation into cybercriminal attacks targeting multiple ATMs around the world. During the course of this investigation, researchers discovered the Tyupkin malware used to infect ATMs and allow attackers to remove money via direct manipulation, stealing millions of dollars. The criminals work in two stages. First, they gain physical access to the ATMs and insert a bootable CD to install the Tyupkin malware. After they reboot the system, the infected ATM is now under their control and the malware runs in an infinite loop waiting for a command. To make the scam harder to spot, the Tyupkin malware only accepts commands at specific times on Sunday and Monday nights. During those hours, the attackers are able to steal money from the infected machine.

I hope you will find it less difficult to understand that duality is one fact, not two contradictory observations (as it seems to be a century ago).

Example: Light (photons) behave like a particle, AND a wave. BOTH are true

Bad example, this isn't two truths, there is only one, the fact that photons have dual behaviour and are not only a particle or only a wave.
Regarding the very statement of the nature of light, there is one truth.
Regarding observed properties of light, there are many, and at least those two properties are valid/verified, but this isn't related to an in-between or non binary truth.

Submission + - Galileo Launch Failure caused by Frozen Propellant Line (spaceflight101.com)

advid.net writes: Commission investigating the circumstances of the Galileo launch failure found that a frozen Hydrazine line caused fuel starvation for 18mn on two attitude control thrusters.

As a result of the incorrect initial attitude during barbecue operations, Fregat did not achieve the proper orientation for the second burn, pointing its thrust vector in an erroneous direction leading to the off-target insertion of the two Galileo satellites.

It remains to be answered why the attitude discrepancies that originated in the first 38 minutes of the mission were not detected by the onboard computer or teams on the ground watching over the vehicle in real time.

It is also unknown whether it is a standard design on Fregat to mount the cold Helium line in close proximity to the Hydrazine pipeline or whether the lines got bundled by accident.


Submission + - God, Darwin and My College Biology Class

HughPickens.com writes: David P. Barash, an evolutionary biologist and professor of psychology at the University of Washington, writes in the NYT that every year he gives his students The Talk, not as you might expect, about sex, but about evolution and religion, and how they get along and how they don’t. According to Barash many students worry about reconciling their beliefs with evolutionary science and just as many Americans don’t grasp the fact that evolution is not merely a “theory,” but the underpinning of all biological science, a substantial minority of his students are troubled to discover that their beliefs conflict with the course material. "There are a couple of ways to talk about evolution and religion, says Barash. "The least controversial is to suggest that they are in fact compatible. Stephen Jay Gould called them “nonoverlapping magisteria,” noma for short, with the former concerned with facts and the latter with values." But Barash says magisteria are not nearly as nonoverlapping as some of them might wish. "As evolutionary science has progressed, the available space for religious faith has narrowed: It has demolished two previously potent pillars of religious faith and undermined belief in an omnipotent and omni-benevolent God."

The twofold demolition begins by defeating what modern creationists call the argument from complexity — that just as the existence of a complex structure like a watch demands the existence of a watchmaker, the existence of complex organisms requires a supernatural creator. "Since Darwin, however, we have come to understand that an entirely natural and undirected process, namely random variation plus natural selection, contains all that is needed to generate extraordinary levels of non-randomness. Living things are indeed wonderfully complex, but altogether within the range of a statistically powerful, entirely mechanical phenomenon." Next to go is the illusion of centrality. "The most potent take-home message of evolution is the not-so-simple fact that, even though species are identifiable (just as individuals generally are), there is an underlying linkage among them — literally and phylogenetically, via traceable historical connectedness. Moreover, no literally supernatural trait has ever been found in Homo sapiens; we are perfectly good animals, natural as can be and indistinguishable from the rest of the living world at the level of structure as well as physiological mechanism." Finally there is a third consequence of evolutionary insights: a powerful critique of theodicy, the effort to reconcile belief in an omnipresent, omni-benevolent God with the fact of unmerited suffering. "But just a smidgen of biological insight makes it clear that, although the natural world can be marvelous, it is also filled with ethical horrors: predation, parasitism, fratricide, infanticide, disease, pain, old age and death — and that suffering (like joy) is built into the nature of things. The more we know of evolution, the more unavoidable is the conclusion that living things, including human beings, are produced by a natural, totally amoral process, with no indication of a benevolent, controlling creator."

Barash concludes The Talk by saying that, although they don’t have to discard their religion in order to inform themselves about biology (or even to pass his course), if they insist on retaining and respecting both, they will have to undertake some challenging mental gymnastic routines. "And while I respect their beliefs, the entire point of The Talk is to make clear that, at least for this biologist, it is no longer acceptable for science to be the one doing those routines."
