Comment What emissions are used for: (Score 1) 141

Yes, because the majority of emissions are from cars, and cars aren't such a minor contributor as to actually be diverting interest and resources away from the major polluters, or even legitimate minor ones

About 13% of global carbon emission is from transportation:

--although transportation accounts for twice that in the US, 28% of the US emissions:

about a third of which is cars.

Comment measured data [Re:Oversimplification] (Score 3, Informative) 141

Scientists dumb down data so science magazines can understand. Mainstream media further simplifies for the general population to understand. Even the summary states that this guestimation is based on a different guestimation of how many gigatons of ice have melted. If 360 gigatons of ice on land melt, it is estimated that it will raise the sea level by 1 mm. However, if the ice is already in the sea, it won't raise the sea level. The dumbed down story doesn't say how much of the missing ice was already in the ocean vs on the land, so we can't use numbers to say that sea level has risen 8mm over that decade.

The 303 gigaton number was for Greenland ice. Greenland ice is on land.

Since we are talking about NASA, why don't they measure the actual sea level instead of playing this numbers game?

They do. Read the linked articles. These are satellite measurements of sea level.

Submission + - Need advice on Enterprise Architect position

dave562 writes: I could use some advice from the community. I have almost 20 years of IT experience, 5 of it with the company I am currently working for. In my current position, the infrastructure and applications that I am responsible for account for nearly 80% of the entire IT infrastructure of the company. In broad strokes our footprint is roughly 60 physical hosts that run close to 1500 VMs and a SAN that hosts almost 4PB of data. The organization is a moderate sized (~3000 employees), publicly traded company with a nearly $1 billion market value (recent fluctuations not withstanding).

I have been involved in a constant struggle with the core IT group over how to best run the operations. They are a traditional, internal facing IT shop. They have stumbled through a private cloud initiative that is only about 30% realized. I have had to drag them kicking and screaming into the world of automated provisioning, IaaS, application performance monitoring, and all of the other IT "must haves" that a reasonable person would expect from a company of our size. All the while, I have never had full access to the infrastructure. I do not have access to the storage. I do not have access to the virtualization layer. I do not have Domain Admin rights. I cannot see the network.

The entire organization has been ham strung by an "enterprise architect" who relies on consultants to get the job done, but does not have the capability to properly scope the projects. This has resulted in failure after failure and a broken trail of partially implemented projects. (VMware without SRM enabled. EMC storage hardware without automated tiering enabled. Numerous proof of concept systems that never make it into production because they were not scoped properly.)

After 5 years of succeeding in the face of all of these challenges, the organization has offered me the Enterprise Architect position. However they do not think that the position should have full access to the environment. It is an "architecture" position and not a "sysadmin" position is how they explained it to me. That seems insane. It is like asking someone to draw a map, without being able to actually visit the place that needs to be mapped.

For those of you in the community who have similar positions, what is your experience? Do you have unfettered access to the environment? Are purely architectural / advisory roles the norm at this level?

If this is actually a credible report, then the U.S. government needs to stop funding the rebuilding/construction of areas that are CURRENTLY under sea level like New Orleans and the dikes and berms around it.

That turns out to be harder than you would think.

Sounds like a typical "dating" site. While doing web work in LA in the mid 2000's I worked for a guy who had three such sites. He paid a small staff of women (like 3...?) to respond to emails/ads from men. Obviously these women had no interest in meeting anyone, and I was surprised how long he was able to string the men along and keep milking money out of them. After working in this office for a few months I got the idea that most sites worked that way. I used two sites myself that I know aren't like that; Plenty of Fish & Match.com. I met my current gf on POF.

Comment Re:Safest it's ever been (Score 1) 71

There is an interesting disconnect in that article. At the beginning of it, it talks about a drop in the total number of hives from the 1940s to "today" (2012, it amounts to a 50% drop). Then it talks about the fact that we appear to be losing 33% of our hives over each winter. How can that be if there was only a 50% drop total from the 1940s to now?

The answer being that beekeepers replace the majority (if not all) of those lost hives each summer. If you want to track this you need to look at how many hives we lose year to year, not from September to May. I want to know how many fewer hives there were last May, not how many fewer than last September.

And thus, "a well regulated militia. . ." yet I don't see the NRA agreeing every person who owns a gun being regulated in any sense of the word nor claiming the same group is part of a militia and should be called up for training by the government.

After all, if you're going to call up a group of people you need to have them registered and that is the last thing the NRA wants despite what the 2nd Amendment says and implies.

But then one day the neural net has a "senior moment" and drives the car off a cliff.

It's actually your geek pride that just plunged to astounding depths.

Computers don't beat humans at chess by playing human chess better than humans. They beat humans by having a deeper view of the combinations and permutations and by making very few mistakes.

A momentary "senior moment" in a self-driving car (I wish I could have rendered that in priapismic scare quotes, but Slashdot defeats me) would just as likely be followed by a Mario Andretti moment 100 ms later as it recomputes several of the box-within-box outer safety profiles ab initio with fresh camera and sensor data. It's so unlike a senior moment as to make my jaw drop (unless you count those senior moments in Quake 3 where you could momentarily see through a solid wall if your POV landed on just the right surface boundary).

You had the whole time you were writing that paragraph to reverse out a bad rhetorical gambit, and never bothered.

What's next in the self-driving car? Liver spots? Bladder failure?

We prevented that problem from the start by putting a lid on the sandbox.

Yes, I know, we shouldn't have to do that. Cat owners shouldn't let their cats do that in our yard. How do you solve that though? Surveil your yard and then follow and identify any cat that ever comes by? Then go argue with each of those cat's owners? What do you do about stray cats? Catch them all yourself?

It's far more practical to just put a lid on it and be done.

IOT is a fail because of manufacturers.

For example, ZigBee connected light bulbs, GE Link, Cree Connected, and Phillips Hue all use their OWN modified protocol. First the use the ZLL protocol instead of the ZHA that they should be using, then they refuse to repeat signals for other brands. So you have some cheap Cree bulbs in entryways and hallways, but have the expensive white color temperature bulbs for elsewhere... Oh they don't mesh, sorry. They also don't mesh with your other devices so you have a horribly broken and fractured mess that barely works.

IoT is an epic fail because we don't have a group of people going to different manufacturers with a sack of rocks and beating the shit out of executives and head engineers. I blame ZigBee and Z-Wave for not forcing companies at gunpoint to follow a freaking standard, but the engineers and executives made the decision to be assholes and intentionally be incompatible.

Real Users hate Real Programmers.
