This lines up with how it took 300 years for the giant tortoise to receive a scientific name. The process to get this required delivering a specimen back to England, and they were just too delicious.

It's been ages since I looked into cloud seeding, so maybe my knowledge is just incredibly out of date... but is there any high quality evidence that it works? I mean, to be clear, working at the scale required for agriculture. By the same token if it does work, doesn't this open a potentially brutal avenue for hydrological warfare/competition?
Edit: Great responses, I learned a lot, thanks!
Maybe and yes. It violates the Geneva Convention. But I’m sure there would be ways to ‘justify it’ if a country wanted to do so.
I had expected that it was not economically viable for agriculture, but the article has one source claiming it is actually quite affordable, given current water prices in the west.
A large portion of the article tries to give both sides a voice.
Maybe we'll have paid mods, but not paid by Reddit, but paid with people and organizations with money, an agenda, and some societal changes in mind.
I'm pretty sure that's already happening in some cases, and not for the good of society.

As someone who doesn't play Factorio, what basic building blocks is this made from? Are there programmable objects or is it built from logic gates?
To make a Minecraft analogy that more people might understand, is it closer to redstone or command blocks?
Factorio only has very basic gates. slightly more advanced than plain redstone, but not anything close to command blocks.
There are three types of combinators: arithmetic, decider, and constant.
Signals have a channel name (one for each item type and a few dozen other options) and an integer value.
Arithmetic combinators can perform arithmetic operations on one or all signals with one signal and a constant integer, or two signals.
Decider combinators perform comparison operations.
Constant combinators emit constant signals on a given channel.
There are also abilities to detect state on some other items and cause behavior to change, the equivalent of observers, dispensers, pistons, etc.

Why was this "a new kind" of credit union? It seems like it was an ordinary credit union that briefly toyed with the idea of BitCoin.
The article doesn't go into much detail, but since they wanted to 'help non-profit workers and the poor' my guess is that they wanted to offer loans to high risk people and the regulators said "NOPE!"
I completed the first two courses in the first four-week block and am currently taking the third course. Mr. Heaton's review provides a really good summary of what to expect.
Overall, I'm also happy with the course. I was expecting a little more degree of difficulty and a little higher workload than what I've run into so far. If you're an experienced developer with a Github account, the first course can be completed in a couple of hours. The R Programming course was more along the lines of what I was expecting. So far, the third class is closer to the first than the second (in terms of difficulty...does require a bit more time).
Going into the course, I wasn't expecting to come out a "data scientist" ready to land a full-time job in the field. My experience so far confirms that expectation. But it's a fun course, a good way to get started in R, and a good way to spring-board your exploration into the field. It's nice to have deadlines as a motivation to keep on track and stay on a track for learning. I'm hoping by the end of the curriculum I feel confident enough to try and land some small free-lance projects.
I'm paying for the "official" certification. I'm not sure if it's really worth it, but at $50/class it's not putting a big dent in my finances.
Same here. The first three were a good start. It was a little annoying that there is zero feedback on the peer assessments other than the grade. The third class starts off slow but by he last week is at about the same level as the R Programming course. My biggest complaint ( which applies to all of these courses) is that the lectures are just narrated PowerPoint presentations. Are all moocs like that? I'm not expecting polished videos at the same level as Kahn Academy but these lectures are just a small step up from fading the slides myself.
Now I'm taking the next three. They are a good continuation that picks up where the first three left off. I was looking forward to the Statstical Inference class. It has been almost 10 years since I took intro to stats in college. For someone without any stats background this course will really step up the difficulty. I was even more disappointed with the lectures on the stats cours. The yellow highlighting as he reads each line on the slide is extremely distracting. But the content is exactly what I was hoping for.
I've done a little hacking with R for data heavy analysis at work when excel couldn't handle the data. I'm really glad to be taking advantage of this opportunity to get more experience with it in these course. My day job is implementing the 'production' side of this kind of data processing with java and hadoop in the healthcare space. Hopefully this specialization will help me better communicate with our clinical/science teams.

From Spring 3 (3.1 I think it was) you don't need to do configuration with XML. Current version (Spring 4) even supports configuring Spring Security with no XML at all. You can configure everything in Java and use profiles (@Profile) when you have multiple configuration scenarios. http://spring.io/blog/2011/02/14/spring-3-1-m1-introducing-p...
Also, don't forget that you can use @Resource (jsr250), not only @Autowired.

> So reuse and decoupling are opposing forces. I find myself siding with decoupling.
The developer has to make a balance between reuse and decoupling. In my opinion everything doesn't have to be 100% reused or decoupled.
Auto wiring is great for test code. Most of you need to know about the test is contained in the testing class.
But I don't like using auto wired in the main code because it means I am required to use that wiring for every use. I find that we want to use classes in a few different ways, and keeping the dependency definitions and configuration values in the XML decouples it from the code and increases both reusability as well as exposing the XML configurations after deployment so that a recompile isn't required in the field.
