Comment Re:Latest LEDs are Too New To Fail Yet (Score 1) 278

Reasonably priced LED light bulbs that put out enough light to be useful for room lighting are a pretty new thing. I haven't seen =$10 bulbs with lumens equivalent to 60-watt incandescents until last year, though it's possible they've been around slightly longer, and I'm still waiting to see cheap LED bulbs that are equivalent to 100 or 150-watt incandescents. And yes, CFLs have been around for a while, and have probably been cheap for 4-5 years, and most of the hard-to-reach light fixtures in my ceilings have them, and sometimes they burn out. These days, if they do, I replace them with LEDs.

Rather than pushing others down, they pull others up by creating jobs and demand.

It takes two people to create a job: one to offer the position, and one to accept it. Otherwise, the job hasn't really been "created." Proponents of trickle-down theory usually seem to ignore this fact.

Meanwhile, those who offer the positions are greedy and are always trying to pay as little as they can get away with, so I wouldn't consider them to be any more virtuous than those who accept the positions.

Comment Smart Watches I've Owned (Score 3, Interesting) 381

I haven't owned any of the current generation of cellphone-accessory smartwatches. The ones I have owned:

-- Casio GPS watch - It was a gift from my wife, back before GPSs had taken over the world. It was big and clunky, got me all kinds of geek cred at work, didn't work very well as a GPS but the fact that it worked at all was amazing.
-- TI EZ430-Chronos watch - programmable, using their MSP430 microprocessor set, had a reasonably flexible display. It didn't have a lot of sensors, and I didn't end up hacking it very much, but it was a lot of fun. It had a low-power radio link that let it connect to a heartbeat monitor band, so you could use it for things like watching your heart rate while jogging.
-- Watches with various other functions built in, like moon phase, tides tables for surfing, that kind of thing. One of them had a screen saver for entirely no good reason, just because it could.

In practice, I find that almost all of the time I'm either in front of a computer screen with a clock display in the corner, or in an environment with clocks around, or carrying a cellphone with a clock display on the main screen, or in an environment that's not very friendly to watches, or in a social environment where I don't really care what time the clock says it is, so I've stopped wearing watches most of the time.

When smart-watches get smart enough to be the phone instead of being a peripheral display for the phone, maybe. But is a smart-watch phone that needs a Bluetooth headset and needs reading glasses to use more convenient than a cellphone with big text that can use a wired headset? For me, it's really not.

Comment And done elsewhere (Score 1) 242

In Tucson 10%ish of the drinking water comes from reclaimed water (aka filtered sewage). Makes sense in an area with not a lot of fresh water resources. Also in those areas you can have different kinds. You can purchase a non-potable (not for consumption) water source for irrigation. Again, reclaimed water, but it undergoes less filtering and thus is cheaper. Plenty of larger places get a hookup to keep their watering costs down.

It is a very sensible way of doing things and you actually have more control of purity than water that comes out of the ground.

I didn't express any hate for the people using the illegal explosives. As a friend of mine says, on a holiday celebrating the overthrow of a government, the question of whether your fireworks are legal or not really just shouldn't come up.

Submission + - Magnetic Field of Earth Weakening a Sign Poles Are Flipping (guardianlv.com)

Trachman writes: The magnetic field of Earth is weakening more rapidly than many scientists thought it would, a sign that Earth’s magnetic poles might flip within a few hundred years as opposed to thousands of years. Data collected from Swarm, the collective name for three European Space Agency (ESA) satellites, confirms that Earth’s magnetic field is weakening, something which has led to many past switches in Earth’s magnetic poles.Deep ocean core studies have confirmed, according to NASA, that the Earth’s magnetic poles reverse on a relatively frequent basis. They usually switch anywhere from 200,000 to 300,000 years. As it has been 700,000 years or so since a flip has taken place, Earth is overdue for one. The weakening magnetic field might be a sign that the switch will occur sooner, rather than later. Scientists, according to a report by LiveScience, had thought that Earth’s magnetic field was weakening by about five percent every hundred years. At that rate, they calculated that a flip in the Earth’s magnetic fields would not happen for around another 2,000 years. However, the new data from Swarm indicates that Earth’s magnetic field is actually currently weakening at a rate of five percent every decade instead of century. That rate is 10 times faster than the scientists had allowed for in their calculations about when the next flip would happen. That being said, we know that the Earth's magnetic field is primary protecting shield from cosmic particles and, consequently, is a primary factor to the Earth's temperature.

My Scoop is following: At the risk of being not popular here at Slashdot I dare to ask: can magnetic field changes and climate changes be connected and analyzed in concert?

Comment Re:Murphy says no. (Score 1) 265

In general, don't do anything that isn't your core business. Or another way of saying it, Do What Only You Can Do.

If you are an insurance company, is building and maintaining hardware your business? No, not in the slightest. You have no more business maintaining computer hardware as you have maintaining printing presses to print your own claims forms.

Maintaining hardware and the rest of the infrastructure stack however, is the business of Amazon AWS, Windows Azure, etc. The "fantasy" you're referring to is the crazy idea that you, as some kind of God SysAdmin, can out-perform the world's top infrastructure providers at maintaining infrastructure. Even if you were the best SysAdmin alive on the planet, you can't scale very far.

Sure, any of those providers can (and do, frequently) fail. Still, they are better than you can ever hope to be, especially once you scale past a handful of servers. If you are concerned that they still fail, that's good, yet it's still a problem worst addressed by taking the hardware in house. A much better solution is to build your deployments to be cloud vendor agnostic: Be able to run on AWS or Azure (or both, and maybe a few other friends too) either all the time by default or at the flip of a (frequently tested) switch.

Even building in multi-cloud redundancy is far easier, cheaper, and more reliable than you could ever hope to build from scratch on your own. That's just the reality of modern computing.

There are reasons to build on premises still, but they are few and far between. Especially now that cloud providers are becoming PCI, SOX, and even HIPAA capable and certified.

Yes. AWS, Azure, etc. are focused on (and are actually pretty good at) providing compute services (whether that be PaaS or straight-up VMs). However, what they are not is contractually responsible for the safekeeping or integrity of your data.

There are definitely use cases for using "someone else's servers." Use them for external-facing resources like a web presence, customer portal, extranet services or even email. But when it comes to business critical systems and data, no one has a more compelling motive to secure and maintain them than an internal IT staff.

I imagine you'll disagree with me, which is fine. I would point out that despite the costs of implementing and maintaining a highly availabile internal virtualization environment, many of those costs are significantly offset by the usage and maintenance contracts as well as network connectivity required to support internal access to "someone else's servers."

In the end, it's a matter of balancing the costs against the criticality and confidentiality of the data, IMHO.

Assuming it would require me to provide personal information, remind me not to do business with whatever company you work for. Then again, if you're a shill for a "cloud" (marketing-speak for "someone else's servers), I understand. Either way, carry on.
