Just in case anyone was going to tell their kids not to go to college.
Some people might tell you not to go to college. Don't listen to them....

Any charts specifically for parents who told their kids to take Mark Lewis' classes? Haha, don't answer that ;-)

Only on laptops. Their TDP is too high for smartphones and tablets. But in the laptop segment, it's gonna pack a punch. And if priced competitively and aggressively, they could win the market! 😀

Here is a nice site that accumulates information about #Scala  in one handy location.

Straw at Saturn's Keeler Gap
The term "straw" in relation to planetary rings was coined during the orbital insertion of Cassini at Saturn when images like the following, available from the JPL site , were taken with high resolution because the probe was so close to Saturn and the rings...

There is a guy who claims that he just deposited his first $100 from tsu into PayPal. I have no idea how big his social network is there. I'm only at $0.06, but very few people from me FB or G+ networks have moved over. I feel like if the usage in my network were larger that type of thing would happen in well under a year.

Similar to me having strong opinions about the nature of life on other planets and the likelihood of it being on Titan. We debate it anyway.

This is a nice article on Kepler-186f, a planet that is 10% larger than the Earth (in radius), and orbits in the habitable zone of its star. Being a bit larger implies to me that is certainly has an atmosphere, and that atmosphere is probably thicker than the Earth's. It isn't a given, but that would be my expectation. So while it is on the outer edge of the habitable zone, I have a feeling there will be a stronger greenhouse effect, and it won't exactly be cold there.

What I really like about this article is at the end when they talk about the implications of the transit approach to planet discovery that is used by Kepler and the systematic bias in it. They also have nice figured of how the method works.
Scientists today announced the discovery of Kepler-186f, a faraway planet that's perhaps the most Earth-like yet discovered. It's the same size as our home world, and at the right distance from its parent star to have liquid water. So, have we at last discovered Earth 2?

They found a way to make cell walls. I still have a feeling that it is hard to run the chemistry of life at any reasonable rate on Titan, but this could be cool to play with.

+Gert Sønderby I believe the we can rule out sunlight given the distance from the Sun and the haze. The intensity of the Sun on Titan is less than 1/100th that of the Earth. You are correct that we don't know about what is going on below the surface on Titan, and there is speculation that there is an ocean under a thick ice crust. I don't know if you can do something like a vent where the vent temperature is well above the local ethane lake temperature, but not hot enough to melt the water ice that forms the upper solid surface. It is an interesting balancing act.

Another use case story for #Scala . This one details the key things they found beneficial with the language. The JVM and type safety seem to be tops on their list. I have to admit that if a project wants to work on the JVM, I can't think of any reason they wouldn't go with Scala. I also love how they mention that they started in Python, then ran into problems as the code base got bigger. To my mind, that boils down to the fact that scripting languages are for scripting. Trying to use them for larger development projects is just asking for trouble.

I'm a believer in the disruptive power of MOOCs, but I don't think this is what he makes it out to be. This is continuing education, not primary learning in the field. Companies like Google only hire people with a significant skill set. This helps those people to stay on top of things or add new skills. It is not a replacement for the original CS degree. Now, if Google and the like were to come out and say that a certain set of microdegrees or nanodegrees were a good entry point to go into their hiring process, that would be something completely different. That might be coming down the pipeline. It might factor into his last bullet on customized degree plans. However, I really don't think this announcement is there yet.

The problem that MOOCs still face is in the level of hand-holding that they can provide. If someone really struggles in CS1, you can't replace the individual interaction with someone in front of a computer/whiteboard talking through things. Right now, students get that type of interaction at a traditional college, which narrows down the flow dramatically for the likes of Google in the hiring process. I can see the MOOCs getting that ability in two ways. The first one is easy, but harder to utilize. You record 1-on-1 virtual chats about certain questions and give students a good way to look those up. You make new ones when questions come up that haven't been answered before, or when new explanations come up that might click for other people. The more distant solution is an AI that can do the hand holding and explanation. Coursera and Udacity will be in the position to make that type of thing a reality, but I'm not willing to venture a guess as to how long it will take.
 
#MOOC mania is alive and well.

Somehow I missed Cicret when it first came out. I'd need to take it for a test run to know if it could really work well, but the idea is definitely promising. The mockup video looks much nicer than the current prototype, but that is to be expected. Can they get the real thing to have the image quality of the mockup? That is the big question, IMO.

Thanks to +Matthew Saxon for sharing this with me.
With the Cicret Bracelet, you can make your skin your new touchscreen. Do whatever you want on your arm! Check out our website.

I love seeing articles like this about #Spark , but it frustrates me a bit that so few of them mention that part of what sets it apart is that it is implemented in #Scala .
Titles can be misleading. For example, the O’Reilly Strata + Hadoop World conference took place in San Jose, California, this week but Hadoop wasn’t the star of the show. Based on the news I saw coming out of the event, it’s another Apache project — Spark — that has people excited. There was, of course,…

The combination of functional and strong support for parallelism makes Scala an ideal language for implementing big big data processing. The following link contains an answer to why the creator of Spark chose to go with Scala. http://typesafe.com/blog/apache-spark-and-the-typesafe-reactive-platform-a-match-made-in-heaven

Story
Tagline
Professor of Computer Science. Author of Scala textbooks. Ring dynamicist, coder, avid roller skater.
Introduction
I use Google+ to share ideas with people, including students. I also find hangouts to be a nice way to "meet" with students when I can't be on campus. If you would be interested in seeing the things I post related to computing, AI, robotics, or other stuff, just let me know.

A possible view of how to run the world in a post-scarcity future: "To each according to his usage. From each according to his desire. Automate the rest."
Bragging rights
It has been said that I make students cry. (Generally by the students.) However, I simply view my job to be working to build a better person, more equipped to handle the world in 5-10 years. If that means I have to completely destroy what they are today, so be it. :P
