Comment So Colorado is safe? (Score 1) 536

Why are Leukemia, prostrate and ovary cancer happening at a significantly (measurable) higher rate in Colorado? It's not a fair question just as the original post's strawman is invalid. The level in Colorado isn't safe because it's natural. Given the slightly better lifestyles measurable in lower obesity rates, one would 'expect' Colorado to be slightly better than average except for melanoma because of the thinner atmosphere/UV radiation.

Would media covering bad places to live ever of that nature be tolerated excluding political motivation or a disaster event? There is a consistency in how information is filtered. There is a natural tendency for the media to keep a wet finger in the air to know which way the wind is blowing. The blowback from standing against the wind and being wrong is far riskier than standing with the wind and the wind being wrong.

You can drop a mouse down a thousand-yard mine shaft; and, on arriving at the bottom, it gets a slight shock and walks away, provided that the ground is fairly soft. A rat is killed, a man is broken, a horse splashes

On Being the Right Size J. B. S. Haldane in 1928

Sextus Empiricus could have told us that 1750 years sooner if he had a mouse, a rat, a spare horse and a thousand-yard mine shaft.

That's why you have the manager sign off on the requirements and functional specification. He can change his mind (and often does as a company better understands the market) but the cost is then his responsibility which he can balance with the potential reward in his decision and communicate a justification to stake holders. If you just make the box, the responsibility is then fairly yours. How was the manager to know the cost of his decision?

Tight algorithms are nice to have for most of the people actually using software. Engineering is an applied science. Engineers solve real problems which means clearly identifying the potential for their investment.

Identify who is going to use the software. Who is this person? Put together a profile on a couple sheets of paper. Have a face for this person. There may be a few personas that will use the software.

Given these personas. How do they accomplish the task you intend to improve today? What is painful in their current workflow? A possible answer is they can't do it.

Given these pain points. Create a list of pain points you can address. When you can say how these will be addressed, they become a functional specification. Part of the functional specification may include performance related concerns if it is driven by the persona.

Given a functional specification, you will need some architectural design to make the implementation possible, document that.

Now you have enough to say how you will test it; some will be unit tests and some will be operational. As you document the testing, you may find your functional specification needs to be more precise.

From there, use what you already know. Improve upon how you implement as time permits but keep the larger picture in mind.

Ideally you will have others review your documentation and code before letting it out the door.

When you are done, everything goes back to the original persona with pain points you are improving. If the tests are passing and the end user is not satisfied, you missed a requirement in your functional specification.

Could Apple Kill Off Mac OS X? 577

Barence writes "When Steve Jobs announced last night that he was 'going to demote the PC and the Mac to just be a device,' it was the clearest indication yet that Apple is phasing out Mac OS X, argues PC Pro's Barry Collins. 'Over the past couple of months, there have been continual rumours that Apple is testing the iPad's A5 processor in its MacBook range, suggesting Apple believes iOS could stretch further than smartphones and tablets,' Collins argues. Plus, Apple would take a 30% cut on all Mac software if it mandated downloads via the App Store only. 'The only part of Apple's portfolio where iOS doesn't make sense is in the high-end. Yet, Apple's already discontinued its Xserve range of servers and... it's almost exclusively fixated on the consumer market,' he argues."

What Filters Are Right For Kids? 678

WaywardGeek writes "My daughter is using phrases like 'hot guys,' and soon will have a chat about the birds and the bees. I believe in letting kids discover the world as it is, and have no Internet controls on any of our systems, which are mostly Linux based. However, it's not fair for aggressive porn advertisers to splash sex in her face without her permission. My question is: What Linux-based Internet filtering solution do Slashdot dads favor, and do they hinder a child's efforts to learn about the world?"

Shuttleworth Proposes Overhaul of Desktop Notifications 306

Thelasko writes "Mark Shuttleworth is considering a controversial overhaul to the way Ubuntu manages notifications." I'm not thrilled with all of the changes proposed, which would mostly value simplicity over confusion at the expense of flexibility and permanence. But anything that would make more people read over and specifically approve the wording of error messages and other notifications is a good thing.

Real-World Benchmarks of Ext4 249

Ashmash writes "Phoronix has put out a fresh series of benchmarks that show the real world performance of the Ext4 file-system. They ran 19 tests on Fedora 10 with changing out their primary partition to test Ext3, Ext4, Xfs, and ReiserFS. The Linux 2.6.27 kernel was used with the latest file-system support. In the disk benchmarks like Bonnie++ Ext4 was a clear winner but with the real world tests the results were much tighter and Xfs also possessed many wins. They conclude though that Ext4 is a nice upgrade over Ext3 due to the new features and just not improved performance in a few areas, but its lifespan may be short with btrfs coming soon."

>> This is the longest, paved, straight, flat stretch of road that the organizers are aware of, in the US.

I'm guessing this could be the tourist attraction North Dakota has been looking for.

The Red River Valley is a prime place for long flat paved roads. Think "curve of the earth" flat.
