VP Anthony Moschella Shows Off Makerbot's Latest Printers and Materials (Video) 35

You may have read a few weeks ago about the new materials that MakerBot has introduced for its 3-D printers; earlier this month, I got a chance to see some of them in person, and have them explained by MakerBot VP of Product Anthony Moschella in a cramped demo closet — please excuse the lighting — at the company's booth at CES. Moschella had some things to say about materials, timelines, and what MakerBot is doing to try to salvage its open-source cred, despite being a very willing part of a corporate conspiracy to sell boxes of Martha Stewart-branded extruder filament — as well as a few unremarkable things that the company's ever-vigilant PR overseer decreed Moschella couldn't answer on the record for reasons like agreements between MakerBot parent Stratasys and their suppliers. The good news for owners of recent MakerBot models: they'll be upgradeable to use the new and interesting materials with a part swap, rather than a whole-machine swap (it takes a "smart extruder" rather than the current, dumber one). And the pretty good news for fans of open source, besides that the current generation of MakerBots are all Linux-based computers themselves, is that MakerBot's open API provides a broad path for 3-D makers to interact with the printers. (The bad news is that there's no move afoot to return the machines' guts to open source hardware, like the early generations of MakerBots, but STL files at least don't care whether you ship them to an FSF-approved printer to be made manifest.)

Getting Charged Up Over Chargers at CES (Video) 33

Posted by Roblimo
from the slip-me-some-of-that-juice-Bruce dept.
First we look at Skiva Technology and their Octofire 8-port USB charger that pulled in nearly five times the requested amount from a Kickstarter campaign. (The 'pulled in X times the requested Kickstarter amount' is becoming a common product boast, isn't it?) Then, for MacBook owners who are tired of having their chargers or charger cords break, we take a brief look at the Juiceboxx Charger Case. These two power-oriented products and WakaWaka, which we posted about on January 9, are just a tiny, random sample of the many items in this category that were on display at CES 2015. Timothy was the only Slashdot person working CES, so it's shocking that he managed to cover as many (hopefully interesting) products as he did, considering that even the biggest IT journo mills don't come close to total coverage of the overwhelming muddle CES has become in recent years.

That's actually what it's like at "Mojave Spaceport". Hangers of small aviation practicioners and their junk. Gary Hudson, Burt Rutan, etc. Old aircraft and parts strewn about. Left-over facilities from Rotary Rocket used by flight schools. A medium-sized facility for Orbital. Some big facilities for BAE, etc. An aircraft graveyard next door.

There is no reason that we have to pick one and abandon work on the others. I don't see that the same resources go into solving more than one, except that the meteor and volcano problem have one solution in common - be on another planet when it happens.

The clathrate problem and nuclear war have the potential to end the human race while it is still on one planet, so we need to solve both of them ASAP.

'Never Miss Another Delivery' - if You Have a TrackPIN (Video) 85

Posted by Roblimo
from the let-me-in-let-me-in-by-the-hair-on-my-chinny-chin-chin dept.
The company is called TrackPIN, as is the product. Its creator, Mark Hall, showed it off at CES. Timothy pointed his camcorder at Mark as he explained how his product would let you get package deliveries safely when you aren't home by giving the UPS or FedEx (or other) delivery person access to your garage, as well as letting in selected people like your maid, your plumber, and possibly an aquarium cleaner. Each one can have a private, one-time PIN number that will actuate your garage door opener through the (~$250) TrackPIN keypad and tell your smartphone or other net-connected device that your garage was just opened, and by whom. You might even call this, "One small step for package delivery; a giant leap forward for the Internet of Things." Except those of us who don't have garages (not to mention electric garage door openers) may want to skip today's video; the TrackPIN isn't meant for the likes of us. (Alternate Video Link)

Sure, there are going to be mediating forces in the environment. Melting is an obvious one. The positive feedbacks have been getting the most attention because they are really scary. It appears that there are gas clathrates in the ground and under water that can come out at a certain temperature. The worst case is that we get an event similar to Lake Nyos, but with a somewhat different mechanism and potentially many more dead. The best case is a significant atmospheric input of CO2 and methane that we can't control.

I don't think I have to discount Trenberth. He's trying to correct his model, he isn't saying there is no warming.

Thanks.

McKitrick is an economist out of his field. Trenberth and Fasullo cite many of their other papers and the publications to which they were submitted, but it seems mostly not accepted. But their conclusion seems to be that there were other times in recent years that the rate of warming decreased for a time only for it to return to its previous rate. I only see the abstract for Kosaka and Xie, but they state "the multi-decadal warming trend is very likely to continue with greenhouse gas increase."

I imagine that the major financial companies make this part of their economic modeling. Most of them do publish weather-related and climate-related advisories regarding commodity and company price trends, etc. How detailed do they get? The wouldn't tell and I am the wrong kind of scientist to ask. Can we make a government or public one? Yes, the level of detail is the big question.

Oh, do I have to qualify that for you, like the hottest outside of a period of Milankovitch Forcing? Gee, maybe the Earth's orbit changed, like back then, and we just didn't notice.

Let's take a look at one of the references you cited:

A section of a draft IPCC report, looking at short-term trends, says temperatures are likely to be 0.4 to 1.0 degree Celsius (0.7-1.8F) warmer from 2016-35 than in the two decades to 2005. Rain and snow may increase in areas that already have high precipitation and decline in areas with scarcity, it says.

It sounds like we have reason to be alarmed.

Well, I am trying to get through to you. You wrote that the hiatus was widely acknowledged by scientists! It's like talking with someone who believes in god - they have no facts, and no facts will convince them, and they create their own "science" which is nothing of the sort to bolster their viewpoint. So, I tried another another argument. But let's go back to the first. Nobody credible believes in a hiatus.

Calling names isn't going to advance your argument.

Orbital models only have two variables when there are two bodies. In reality we are always dealing with an n-body problem. Regarding atmospheric models, we have weather, which is too chaotic to forecast, and climate, which should not be.

We could sit back 100 years and see what is happening then, so that we have lots of good data points, but potentially at the cost of widespread famine, death, etc.

We have excellent reasons to stop releasing sequestered carbon even if we ignore global warming.

If they can pull more people out of poverty, what the U.S. does won't matter to China and India because their domestic markets will be larger than the United States. Currently they have even worse social inequity than we do, and the poor performance of their own markets forces their own people to look elsewhere for work.

Yes, I'm also a solid Democrat. But this has been a long time coming and IMO it's even in line with Obama's recent agenda on the Middle Class! The problem with the guest worker programs is that they devalue the local workers by diluting the market for them. The effect is to create a sort of "disposable worker" from our own citizens.

Now, of course jobs can be sent overseas too, but if the alternatives are to have foreign workers work at home, or in the U.S., neither choice is a win for our own citizens.

It continues to seem silly to have such a thrust on STEM education in the U.S. when the job market for STEM workers consistently goes to overseas hires, whether they are here or in their home nations. We need to work on the job-export issue as well.
