    If all recursive functions can be written iterative, then what's up with the Ackermann function?

    Per my understanding, all recursive functions can be written iteratively. We can at the very least simulate the runtime stack used in recursion with an explicit stack for an iterative solution.

    However, it's also my understanding that the Ackermann function, which is not primitive recursive, cannot be computed iteratively.

    Clearly both of these statements cannot be correct, and I'm trying to find the gap in my understanding. Thanks!

    Lulu Qian - "A Future Written by Molecular Programmers"

    Posted: 02 Jan 2018 11:17 AM PST

    Very interesting talk about research The Qian Lab is conducting. Their research focuses on the intersection of bioengineering and computer science. https://www.youtube.com/watch?v=mV7FUOhDcs8

    Here's a description of the talk:

    "A Future Written by Molecular Programmers" Lulu Qian, Assistant Professor of Bioengineering, is interested in engineering molecular systems with intelligent behavior: specifically, exploring the principles of molecular programs in nature with the end goal of recreating synthetic molecular programs that approach the complexity and sophistication of life itself. To this end, she works on designing and constructing nucleic-acid systems from scratch that exhibit programmable behaviors from the basic level—such as recognizing molecular events from the environment, processing information, making decisions, and taking actions—to the advanced level, such as learning and evolving.

    Is modulo actually used in barcode error checking?

    Posted: 02 Jan 2018 08:15 AM PST

    https://imgur.com/gallery/75Jtm using this image, I'm trying to teach my compsci students about error checking in barcodes and later we'll use QR codes. I'm a little confused though by the term modulo being used next to the 7. If you direct your attention to the bottom of the image you'll see the formula used to get to the #23, then apparently to error check you can take the next highest power of ten (in this case 30) and subtract 30-23 to get 7. Why use the word modulo?

    computer Science vs Data science vs information science

    Posted: 02 Jan 2018 12:17 PM PST

    As a college freshman, I'm still not too sure of the differences between the 3 majors. I'd like to know of key differences and what type of person should pursue each major? Thanks!

    I'm really hoping to get your Input on Online Programming Community Leadership survey as part of my final thesis requirement [Please].

    Posted: 02 Jan 2018 04:07 AM PST

    Dear Ms./Mr. (Honored Admin & Respectful Members) ,

    I'm Abdul Razak, studying at Universiti Utara Malaysia. I really need your help by humbly requesting to fill in my estimated 6 minutes survey if you have ever participate in any online programming communities to learn, asking for help, sharing knowledge, developing software/programs and joining any other activities ( such as Java programming forum, codeguru.com, Python forum, PHP Community, Android/IOS community, Matlab, Codeacademy.com and others).

    I have collected 120 respondents for 2 months and 1 week now. I need 300 participants to accomplish data collection and analysis for my final thesis. Below is the survey link :

    https://www.surveymonkey.com/r/abdulrazak123

    [Lucky Draw of USD 10 Amazon gift card x 6 respondents ] will be delivered to random six respondents as an appreciation for participating.

    "Your willingness to answer this survey is highly appreciated"

    Thank You Very Much

    Artificial General Intelligence Design

    Posted: 02 Jan 2018 01:21 PM PST

    I am working on building on my A.I prototype for users to create and license their own custom artificial intelligence for the job or career they want. I see this as a way for general intelligence to come to fruition. I am wondering how can this be designed to fit the user.
