I use shapeways stainless steel 3D printing to make parts for physics experiments. It's only useful when the parts are small and can have sloppy tolerances. But in these cases it saves a fortune. I recently had a dozen small parts made for $200 that would have cost $1000 made by conventional machining. You can make screw threads (1/4 - 20 and larger; 10-24 might work) by printing the thread and then chasing the printed thread with a die or tap before use.
We killed just about all of the bison in North America in the 1870's. We killed them for their skins, and the cows that replace them taste good. We are poorer for it- the great plains are boring and nobody goes there for a safari. It will be an even greater loss if the same happens in Africa, because they still have the top predators that were lost in North America tens of thousands of years ago.
Um, no. There are many kinds of lawyers out there. Companies of this size either have in-house or outsourced lawyers specifically for the purpose of writing contracts clearly so that things don't end up in litigation when something goes wrong. A lawyer that produces an unambiguous contract, which anticipates how things might go wrong, is a great asset.
Yes, there will always be some chance of a successful attack, but I think it is wise to expend effort to make attacks very difficult. I don't want my president's decisions to be guided by fears for his personal safety. Similarly, I don't want people to avoid becoming president for that reason. Otherwise, those who would threaten the president's safety influence policy. It is hard to conceive of a worse way to make policy, and I am glad that John Wilkes Booth and those who followed him have not had (so far as we know) much influence on policy before their assassinations.
I'm all for taking a step back and reducing policies that make people want to kill Americans. But I don't want that policy decision to be made under threat.
Figuring out anti-drone measures sounds very reasonable to me since the recent advances in drone technology are also applicable to making flying bombs.
Actually we have lots of control. We are the people buying so much of the plastic stuff made in China; we can make those purchases conditional on how the plastic is made.
What we don't have in the US is the political will to flex that muscle, because it might disrupt someone's profit. So we only flex it to solve little problems, like Pakistani children sewing soccer balls.
Most prosecutors have the common sense not to press chid-porn possession charges against minors who photograph themselves. They know a change in the law here is long overdue, and is difficult for legislators because no politician wants to be seen as softening punishments for child pornographers.
We'll see if any prosecutors have the sack to go after cops who spread these photos.
Timothy Lord: Chris, can you explain your role with GitHub?
Chris Kelly: Yes, so you know, I do all of our outreach work. So, it’s us going out into the world, talking to people and getting them involved in their communities and really trying to amplify the work that’s already being done in the OpenSource world and how GitHub can support and promote that.
Timothy Lord: GitHub started obviously with Git, talk a little bit about the progression of going from a particular organization tool to having how many repos right now?
Chris Kelly: We have about 18 million public repos currently and we’ve got 6 million active users with accounts, so it’s gotten pretty big. So Git is what, 10 years old next year and so we started with that. It was just – the founders were really are getting involved with Git and needed a solution for solving like sending patches around via email problem, which was kind of a nightmare and so started building GitHub for themselves and that’s how the company has built itself all the way up for the last six years is building the tools to solve the problems that we have and we are all software developers and so it’s grown that way.
Timothy Lord: And it’s not like there is a lot of advertising that goes around saying to use GitHub; GitHub has grown pretty organically?
Chris Kelly: Yeah, so a lot of it has to do with our outreach. Being at conferences, meeting people, and really understanding what their problems are and really just being supportive of the community and then I think that’s the best way to really engage with any kind of audience, any company that’s interested in engaging with the developers is go be developers and go be part of the community. You can’t sell to that audience, you can just be a part of that audience and that really works.
Timothy Lord: Talk about some of the big projects that are on GitHub right now and what sort of scope, we’ve got one aspect of the scope of the entire site is number of users, but talk about some projects and how many commits you see happening?
Chris Kelly: Oh, I’d have to look at some graphs for number of commits. But we have really large projects coming on to GitHub all the time. Microsoft just put Typesafe on to GitHub recently. We’ve got the Rails project, is one of a classic example that the number of commits spiked the second I think Rail moved onto GitHub and started doing the development cycle. So we’re finding that a lot of open source projects, very large ones are moving under GitHub and seeing a lot of adoption and engagement from the community because we think we make it so much easier to both communicate about the project as well as contribute back to it.
Timothy Lord: Talking about the actual development because obviously people use GitHub as their own tool for developing software of their own. What’s the development work like for the software that runs GitHub?
Chris Kelly: So we used GitHub to do everything basically. So it manages all components of the way we work, so between GitHub itself and our open source chat system Hubot that sits on top of Campfire and Slack and HipChat. We can do all things you have in the very open and so that’s what we built GitHub for, is to try to change companies to start working more and more open and so we do it in the open, every project and every product feature gets talked about really publicly and everyone can contribute to that conversation. Everything that happens in our office, the events we put on, all happen in GitHub repos. The planning of this conference and showing up here is done in the GitHub repo. We do literally everything, GitHub repos with issues and port requests, because we think it’s the right way to work and so we’re really kind of stressing the way GitHub can function by doing that and then going on to the world and talking to other companies and that want to change the way their development cycles go and so that’s wha
I know this is an unpopular viewpoint, but I'm beginning to think that Tokamak is a way to funnel tax dollars into researcher's pockets. If we ever do achieve practical commercial fusion, we may look back at the Tokamak like modern pilots look back at the manned ornithopter attempts of the 1800's.
But if the Tokamak ever is made to be commercially viable, we're probably talking about a few gigantic power generators, which would mean we probably need to do something about that decades-old power line infrastructure.
You are correct. My old physics advisor was a nuclear theorist who knew the fusion crowd in the seventies. He told me "Stay away from fusion. If you want to lie for a living, become a lawyer. It pays much better."
A big part of this trend is the aging of pilots trained in the Vietnam war. The youngest of them are in their 60's. When the war ended, the US government's "learn to fly for free*" program sharply contracted.
I'm a cat owner. This average sounds about right to me. But keep in mind that this is an average, not a median, and the average is skewed upward by a small number of people* who spend thousands a year to fix problems that inevitably arise in their older pets. Cat chemotherapy, for example, costs about $100 a week.
*Who are these people? The wealth distribution of the united states is also highly skewed, with a long tail at the high end.

I'm not surprised. Probably because we killed all the wolves.

Assuming they were motivated by the recent epidemic, they created this marketable test in ~ 6 months. Bravo.

Doesn't that mean that if one is counting calories, one should only eat the shit of fat people? ;)
You can. In the case of nested disks with the same focal spot, this is called a zone plate.

If misery is the only thing that can stop a population from growing, then that population will grow until it is miserable.
The originals were probably made of naval brass, which has a little tin added to prevent dezincification. Or they might have been cupronickel.
