    2. #DataScience Hive mind: I’m writing an article about the career path for job-changers who want to get into data science fields. I’d love your input.

      It’s no secret that data science is a good career path. The jobs are in demand, the salaries are compelling, and the work is interesting. So how does someone break in? In particular, I’m...

      It’s no secret that data science is a good career path. The jobs are in demand, the salaries are compelling, and the work is interesting. So how does someone break in?

      In particular, I’m interested in how an experienced IT professional can move into data science. What advice would you give to someone with, say, five years of computing experience, who wants to break into the field? Tell me about the skills required, where you’d tell your friend to go to acquire them, and how to get a job without a specialized degree. What would make you say, “I want to hire this person, even if the individual lacks the relevant schooling”?

    3. A common misconception is that the risk of overfitting increases with the number of parameters in the model. In reality, a single parameter suffices to fit most datasets

    4. What are some examples in gaming of things that were ahead of their time?

      I recently read a book about Nintendo and Sega in the 90s, and it reminded me of something I'd long forgotten: the Sega Channel. The idea that the Sega Genesis had a digital delivery system in...

      I recently read a book about Nintendo and Sega in the 90s, and it reminded me of something I'd long forgotten: the Sega Channel.

      The idea that the Sega Genesis had a digital delivery system in 1994 is wild to me. For comparison, Steam didn't have its first release until 2003, nearly ten years later!

      What are some other examples of games, hardware, or ideas that were ahead of their time?

    5. Do you have any odd or unusual fears?

      For example: I've got mild issues with what I'll call "big dark things within emptiness." I'm sure there's probably a very specific term and associated subreddit for this, but I don't particularly...

      For example: I've got mild issues with what I'll call "big dark things within emptiness." I'm sure there's probably a very specific term and associated subreddit for this, but I don't particularly enjoy searching it up.

      An example would be looking at a planet in Celestia or Google Earth, especially the unlit side. Another example would be seeing the hull of a submerged ship underwater. I have no idea why these kind of things give me the willies, but they do.

      Intellectually I think it's absurd and will often try to will myself to ignore the nonsense feeling based on completely unthreatening stimuli, but that doesn't seem to alleviate my instantaneous lizard-brain reaction. For whatever reason, I can't get past it.

      It's been this way for a long time, too. I can remember when I was very young, I had a picture book about space. It had shots of all the planets, most of which I was fine with, but there was a close-up of Jupiter in shadow that I would deliberately avoid looking at.

      Another book had a very dark picture of a giant squid that caused the same reaction in me. I remember memorizing the page numbers for these two photos so that I could skip them whevener I looked at the books. If I ever opened the book to a random page, I would crack it ever so slightly so that I could peek the page number to make sure it was safe.

      Do you have something like this? Some absurd fear, phobia, or aversion to something strangely specific or benign? When's the first time you realized it? Has it stayed that way over time?
