    Is it worth paying for say an edX course certificate?

    Posted: 11 Oct 2018 12:17 AM PDT

    Just trying to get a feel for your general opinion here. I'm in a non-CS job. Bored. I'd like to add some CS skills to my CV. Or, is doing them for free OK, as long as I do it thoroughly? Thanks Update: Wow! I didn't expect such insightful responses. Thank you . I'm going to pay for one, anyway, as it's cheap, just to support edX, and I can claim it as a business expense. I'll do some others just for fun.

    Is there a Blog or Website you go to on the Daily?

    Posted: 10 Oct 2018 08:23 AM PDT

    As a CS college student, I'm always looking to learn and keep on top of tech news and entertainment, but also wanting to better myself and my knowledge to become a great future Software Engineer!

    I feel like there are many resources out there I don''t know about and places I can go often to expand my mind...

    Do you kind people of Reddit have any favorites?

    Are venus fly traps turing complete?

    Posted: 10 Oct 2018 04:41 PM PDT

    I recently learned that a venus fly trap has hairs on it's "mouth", if two of those hairs are triggered within 20 seconds, the trap will close. So it will close if hair 1 AND hair 2 are triggered.

    If we abstracted fly traps into just "<" shapes with two little hairs inside which when triggered together, cause the trap to shut, you could theoretically arrange them in a pattern that when one closes, it pushes the other to close like this <<<<< and now you have a domino affect similar to signal propagation. Connect two signals to one fly trap leaf so that each would hit only one hair when they close and now you have a functioning and gate.

    Join two signals together and now you have an or gate.

    I bet someone creative enough can create a not gate if you really think about the mechanical properties and find the right arrangement.

    You also have storage (the traps stay closed for up to 12 days). Make it so when it opens again, it triggers a signal to itself and now you have a clock.

    Optimized Image Feature Extraction / Categorization

    Posted: 11 Oct 2018 01:06 AM PDT

    Following up on my previous posts (which have been quite popular so far on this thread) regarding algorithms rooted in information theory that identify structure in images, I've come up with a series of algorithms that together allow for very fast image categorization.

    These algorithms rely on the same image partition algorithms I posted about previously ( link here ) that can identify structure in an image with no prior information. This new set of algorithms optimizes the approach by testing for the point at which the structure of the regions identified by the algorithms begins to "crystallize". That is, the algorithm stops partitioning the image at the point where the structure of the resulting partition is most stable.

    I've also posted an algorithm that can compare images that have been processed using this technique in a fraction of a second, though pre-processing an image takes anywhere between a few seconds and a few minutes, depending upon the size and complexity of the image.

    Theory, code, and examples here:

    Not a CS student but interested in studying a course in algorithms

    Posted: 10 Oct 2018 01:44 PM PDT

    So I'm a student studying electrochemical engineering. I'm interested in studying some courses about algorithms such as algorithm design or algorithm implementation. However as a non-CS student, I'm wondering how much of what I'll learn about algorithms can I apply to my own field. So I'm wondering how have you guys applied what you learnt in your algorithm courses to your work?
