Hadoop is not a magic thing that can all of a sudden produce reams of new data sets. The setup, on an enterprise scale, takes thousands or tens of thousands of dollars in hardware. Then you have the Map/Reduce jobs to create as well as pointing all your data to the new clusters. Then the tweaking starts, and then your pointy haired Boss or Accounting PencilTwit comes to you and demands results for all of this capital expense you just had them buy for some pinhead to get a better dashboard in sales.

Hadoop, done right, takes many departments to work on and organize in a big enterprise. Small shops may have one guy who is both SA and Programmer who could get the job done enough to make a difference. Furthermore, you NEED a full install from a big vendor. Installing Hadoop from OpenSource is a nightmare, and the big vendor's make it painfully simple to get the job done quickly. Can you do it by hand? Sure. Do you have the time? Not when you have other projects to work on and you can spend the companies capital to get the install and config done in 1/10th the time. /Cloudera Certified //A year later and they still don't know how to get data through the pipeline ///Setting up the hardware was a BLAST!

Comment: Skip Lasik: Go PRK (Score 1) 550

by bigdady92 (#47525001) Attached to: Laser Eye Surgery, Revisited 10 Years Later

I live a very active lifestyle. I do martial arts, dive, play sports, a whole bunch of things that having that lil 'flap' be a problem if it were to ever 'pop' open. Thankfully I spent the extra cash and went with PRK which is the same surgery Air Force pilots get.

What is the big difference? : Simple, there is no flap. They carve off the top of the cornea's layer is removed and is then grown back. No flap, no popping, no worries.

What is the downfall: 3 days of light blinding pain whenever bright light occurs. Thankfully this is negated by modern medicine and covers for your eyes.

What is the upside: This is the first type of LASIK ever invented so it's been done brazillions of times. This is perfected to a state of art and I've had no issues in the 10 years since I've done the surgery. Best money ever spent and not one chance if getting poked in the eye or underwater accident that this 'flap' may (1/1000) pop open.

Was it overkill? Perhaps. But that's one less thing I ever have to worry about.

The death of GReader led me to Feedly which has nearly all of the features that GReader had backed by a company whom RSS isn't an experiment and truly GOT RSS. Feedly saw a need in the market place and filled that void that Google abandoned.

I am more than happy with Feedly and their feature set. I threw them some money to support them and tell everyone I know to use them as their apps work just as well if not better than what Google was trying to do.

There is no mention of speed, performance, file copy replication, the ins and out of each solution, just a list of features they all share and how the author went about determining them at his whim. Without metrics this article is just a sales blurb for links. Other websites do it better: Storagereview for one, Smallnetbuilder is the other.

Another wretched sales brouchure disguised as a review by Infoworld.

First Fully Electric Manned Helicopter Flight 86

Posted by timothy
from the not-yet-for-the-daily-commuter dept.
cylonlover writes "On August 12, electrical/aerospace engineer and helicopter pilot Pascal Chretien took to the sky in the world's first untethered, fully electric manned helicopter flight in a prototype machine that he designed and built almost entirely by himself within a 12-month development period. In his 2-minute, 10-second test flight, Chretien beat aviation giant Sikorsky into the record books — but it was not without significant risk. As the man himself puts it: 'in case of crash I stand good chances to end up in kebab form.'"

Jetman Attempts Intercontinental Flight 140

Posted by samzenpus
from the a-jetwing-and-a-prayer dept.
Last year we ran the story of Yves Rossy and his DIY jetwings. Yves spent $190,000 and countless hours building a set of jet-powered wings which he used to cross the English Channel. Rossy's next goal is to cross the Strait of Gibraltar, from Tangier in Morocco and Tarifa on the southwestern tip of Spain. From the article: "Using a four-cylinder jet pack and carbon fibre wings spanning over 8ft, he will jump out of a plane at 6,500 ft and cruise at 130 mph until he reaches the Spanish coast, when he will parachute to earth." Update 18:57 GMT: mytrip writes: "Yves Rossy took off from Tangiers but five minutes into an expected 15-minute flight he was obliged to ditch into the wind-swept waters."

+ - Colossus 3.5-in SSD Combines Quad Controllers->

Submitted by Vigile
Vigile (99919) writes "The new Colossus SSD comes in capacities starting at 256GB and going all the way up to 1TB in a standard 3.5-in hard drive form factor. This larger size was required because the drive actually integrates not one but FOUR Indilinx SSD controllers and THREE total RAID controllers in a nested RAID-0 array. All of this goodness combines to create an incredibly fast drive that beats most other options in terms of write speeds and is competitive in read tests as well. Using some custom "garbage collection" firmware, the drive works around the fact that TRIM commands aren't supported in RAID configurations to maintain high speeds through the life of the SSD."

This is an easy one:

In a murder someone dies, there is pain and closure. It happens and there is nothing you can do about it, someone is dead.

Sex crimes are where the victim lives to tell the tail. The lingering "pain" and "emotional suffereing' cause this to be a more serious crime to society as both the perpetrator and the victim still live.

Death is a finality. Rape lasts for a lifetime.

Anyone else see this as a rehash of good ole Dragon's Lair? I must be "ancient" in terms of computer game knowledge but we had this back in the 80s and the game was savage as hell. All this talk of "Oh no major game overs, players can die and the story goes on" Is hooie. You need lightning reflexes, perfect time, and coordination of a ninja juggling flying Molotov cocktails balancing on a ball being shot at by assassins.

Longer story, more plot, but in essence same gameplay as 30yrs ago.

<b>TLDR: I hated Vista. Loved XP. Use Linux. Installed 64bit Vista. Vista Crashed and burned. Reinstalled with SP2. It just Works.</b>

I've been a longtime XP user. I use Ubuntu and RHEL at work. I use linux and unix. I hated Vista with a passion, thought it was a PIA and had so much config problems. I then bought a new PC (quad core 6GB ram, blah blah) so I figured I'd put Vista on it. First time worked ok. I updated my bios, it blew away my Raid 1. Got irritated and stopped screwing with it. Then SP2 came along in the last few weeks and I reinstalled my OS and installed SP2 over it.

It just works. Works perfectly. So simple to install Vista and simple to install the SP2. 2 reboots and I had everything working. Fixed the RAID issue, fixed the bluetooth issue, fixed some other quirks that drove me batshiz crazy.

I gotta say that I used to hate vista with the passion of a 1000 firey suns. Now I'm like "Well it's not too bad, what's the problem with it again?"

+ - Boeing Dismisses Claims of Senior Engineer

Submitted by Seakip18
Seakip18 (1106315) writes "An Senior Engineer for Boeing, Vince Weldon, has argued that their new 787 airplane is deadlier than normal, metal framed airplanes. To his credit, he has worked with composites since 1973. Boeing has denied his claims, insisting that their airplane testing has no dangers to merit his claims.

...Weldon alleges:
The brittleness of the plastic material from which the 787 fuselage is built would create a more severe impact shock to passengers than an aluminum plane, which absorbs impact in a crash by crumpling. A crash also could shatter the plastic fuselage, creating a hole that would allow smoke and toxic fumes to fill the passenger cabin.
-After such a crash landing, the composite plastic material burning in a jet-fuel fire would create "highly toxic smoke and tiny inhalable carbon slivers" that "would likely seriously incapacitate or kill passengers."
-The recently conducted crashworthiness tests — in which Boeing dropped partial fuselage sections from a height of about 15 feet at a test site in Mesa, Ariz. — are inadequate and do not match the stringency of comparable tests done on a 737 fuselage section in 2000.
-The conductive metal mesh embedded in the 787's fuselage surface to conduct away lightning is too light and vulnerable to hail damage, and is little better than a "Band-Aid."
An OSHA claim by Weldon for illegal firing was also denied. The company stated in the OHSA report that he was fired for threating his supervisor."

We can defeat gravity. The problem is the paperwork involved.
