Which OSS Clustered Filesystem Should I Use? 320

Dishwasha writes "For over a decade I have had arrays of 10-20 disks providing larger than normal storage at home. I have suffered twice through complete loss of data once due to accidentally not re-enabling the notification on my hardware RAID and having an array power supply fail and the RAID controller was unable to recover half of the entire array. Now, I run RAID-10 manually verifying that each mirrored pair is properly distributed across each enclosure. I would like to upgrade the hardware but am currently severely tied to the current RAID hardware and would like to take a more hardware agnostic approach by utilizing a cluster filesystem. I currently have 8TB of data (16TB raw storage) and am very paranoid about data loss. My research has yielded 3 possible solutions: Luster, GlusterFS, and Ceph." Read on for the rest of Dishwasha's question.

On android phones, there are alternative keyboards you can use that are optimized for use on a capacitive touchscreen. A qwerty-keyboard with small keys on a small screen is annoying, as it requires modifier-keys or slow long-presses to switch between text, numbers and symbols. Yes, you can use auto-suggest to speed plain old text typing (such as swype), but that only works for regular text. The alternatives presents a keyboard with large keys that can have all of those at a single, speedy gesture.

My favorite is messagease. It makes optimum use of touchscreen capabilities. E.g. on a single key you can do a single tap, a swipe in 8 different directions (and back for even more options like capitalization), and things like drawing a circle clock-wise or anti-clockwise. Using a single (large) key you can input many different characters this way. Especially power users will love this. Similar to using powerful editors like vim, there's a learning curve. But once you master it, you will love every second of it. Since this is that you use very often, it is worth investing some time to learn it. And honestly, this one is not hard or frustrating to learn; there's a simple game included that will get you up to speed in a matter of weeks.

I use this keyboard to fix things on the go without being frustrated by how horrible a normal keyboard layout is when using a terminal emulator. It's even better than a physical keyboard on a smartphone. No, I do not make money off of this keyboard, it's just one of the greatest tools I've used since I mastered vim ages ago.

Except that you're more than a little likely to run into something else that you will waste time on, thereby once again avoiding the issue that is _really_ at stake here. This is fighting the symptoms of a problem, not actually tackling the problem that's apparently bothering this person.

Yeah. Imagine, if you will, that capacity will double every 1.5 to 2 years. 10 Years from now, we'll have phones that are 30+ times faster than what we have now. With that hardware, who needs PC's?

Just put the phone on a dock and use the attached screen/keyboard/mouse as your computer. PC's will go the way of the workstation for professionals and enthusiasts. That's why Microsoft is desperately clawing its way back into the mobile OS.

What US Health Care Needs 584

Medical doctor and writer Atul Gawande gave the commencement address recently at Stanford's School of Medicine. In it he lays out very precisely and in a nonpartisan way what is wrong with the institution of medical care in the US — why it is both so expensive and so ineffective at delivering quality care uniformly across the board. "Half a century ago, medicine was neither costly nor effective. Since then, however, science has... enumerated and identified... more than 13,600 diagnoses — 13,600 different ways our bodies can fail. And for each one we've discovered beneficial remedies... But those remedies now include more than six thousand drugs and four thousand medical and surgical procedures. Our job in medicine is to make sure that all of this capability is deployed, town by town, in the right way at the right time, without harm or waste of resources, for every person alive. And we're struggling. There is no industry in the world with 13,600 different service lines to deliver. ... And then there is the frightening federal debt we will face. By 2025, we will owe more money than our economy produces. One side says war spending is the problem, the other says it's the economic bailout plan. But take both away and you've made almost no difference. Our deficit problem — far and away — is the soaring and seemingly unstoppable cost of health care. ... Like politics, all medicine is local. Medicine requires the successful function of systems — of people and of technologies. Among our most profound difficulties is making them work together. If I want to give my patients the best care possible, not only must I do a good job, but a whole collection of diverse components must somehow mesh effectively. ... This will take science. It will take art. It will take innovation. It will take ambition. And it will take humility. But the fantastic thing is: This is what you get to do."

Does the Internet Make Humanity Smarter Or Dumber? 282

from the it-sure-does dept.
Nemilar writes "The Wall Street Journal is running a pair of articles asking whether the Internet is making humanity smarter or dumber. The argument for smarter is that the Internet is simply a change in the rules of publishing, and that the bad material is thrown away; the second story critiques the 'information overload' aspect of the Internet, claiming that we have traded depth of knowledge for velocity and span. What do you think? Does the Internet make you stupid?"

Happy Towel Day 122 Screenshot-sm

An anonymous reader writes "While Douglas Adams continues his attempt to set a new record for the longest extended lunch break, geeks all over the universe pay tribute to the beloved author by celebrating the tenth edition of Towel Day. Towel Day is more alive than ever. This year Richard Dawkins, one of Adams' best friends, has tweeted a Towel Day reminder to his numerous followers. The CERN Bulletin has published an article on Towel Day. There has been TV coverage and there will be a radio interview. The Military Republic of the Deltan Imperium, a newly formed micronation, has recognized Towel Day as an official holiday. In Hungary several hundreds of hitchhiker fans want to have a picnic together in a park. And there's a concert, a free downloadable nerdrap album, a free game being released, the list goes on and on."

Game Endings Going Out of Style? 190

Posted by Soulskill
from the to-be-continued dept.
An article in the Guardian asks whether the focus of modern games has shifted away from having a clear-cut ending and toward indefinite entertainment instead. With the rise of achievements, frequent content updates and open-ended worlds, it seems like publishers and developers are doing everything they can to help this trend. Quoting: "Particularly before the advent of 'saving,' the completion of even a simple game could take huge amounts of patience, effort and time. The ending, like those last pages of a book, was a key reason why we started playing in the first place. Sure, multiplayer and arcade style games still had their place, but fond 8, 16 and 32-bit memories consist more of completion and satisfaction than particular levels or tricky moments. Over the past few years, however, the idea of a game as simply something to 'finish' has shifted somewhat. For starters, the availability of downloadable content means no story need ever end, as long as the makers think there's a paying audience. Also, the ubiquity of broadband means multiplayer gaming is now the standard, not the exception it once was. There is no real 'finish' to most MMORPGs."

Comparing a server idling to a car in front of a red light is seriously wrong. Servers in general tend to spend a _lot_ more time idling than cars wait for a red traffic light. There'll always be servers that _do_ fully utilize their resources, but most of them will idle a lot. So it makes perfect sense to take that as a generic guide-line.
