Nope, I definitely do not have human calculator abilities. I'd solve your example problem with long multiplication, and would likely be unable to do so without pen and paper. The only difference is that each single digit multiplication

Negatives are the same shape as their positive counterpart, but the inverse. So where there would normally be a shape for the number, there's instead a void or impression that wants to be filled.

No color associations for me. In fact, I mostly "feel" the shapes I describe in the article rather than seeing them constantly. The pictures I ended up drawing are what the shapes would look like if you could drag them out into th

My visualizations are definitely heavily base-10-centric. I did some experiments with visualizing numbers in other bases while doing this writeup, and I've come to the conclusion that I just convert each digit to its base 10 equivalent

Some low primes above ten are slightly pointier than I'd expect them to be (not sure where that expectation is coming from...), but that trend doesn't continue for very long - stops way before triple digits. I think it's like

Thank you! I didn't include them because there aren't many, but I can expand a bit here. Beyond 10, it's mostly classes of numbers that have unique forms, rather than the numbers themselves. So 15, 25, and 35 to some extent a

I'm now pretty convinced that this could be classified as some form of synesthesia, though I'd never thought of it that way before. When I'm actually doing math I tend to _feel_ the shapes of the numbers and their interaction

While writing this article, I learned that Ed Catmull has aphantasia. It's amazing to me that someone with a Turing award for work on computer graphics can't mentally "see" those graphics when he closes his eyes. It&#x27

I recognize these, but they're not what come to mind when I think of my early math education (mostly times table worksheets, or seeing a teacher do long division on the whiteboard.) Definitely possible that they influenced my thinking,

That description is eerily close to how I feel. Seven for me is definitely a very "loosely bound" number, and it wants to separate along the three and the four.

Negative numbers are just like the positive ones, but kind of... the opposite. Like the indentation formed if you pressed the positive number into clay or sand or something. It's like they want to be filled or take away from something

Author here: was definitely not trying to frame this as a tutorial or anything like that. I don't think that my "methods" have any particular advantages. It's just how my brain works.

Author here - like one of the other commenters said, I don't think there's anything wrong with your approach, or any way of thinking for that matter. I don't think there's anything particularly "right" or advan

I'd definitely agree that this is overkill for most people. In your case, though, I think that you could put the same amount of work into GnuCash and get the same results without writing any code. Plus you'd have a GUI with built

This is exactly what made me switch away from ledger. I thought that a command-line/plaintext only workflow would be great, because that's what I usually prefer. However, a GUI + autocomplete just ended up being way more useable

I also wasn't super sure about sticking "simple" in the title, but while writing this article and going through the GnuCash setup steps, I actually started to feel like it was appropriate. As another commenter mentioned, I th

And that's definitely an important shortcoming in GnuCash. I don't know of a great way to deal with transactions that go beyond "categories". You could use the description field + custom reporting, but that seems a bit e

The very first plot shown in the article was generated with custom scripts, published here ( https://github.com/csun/simple_gnucash_budget_plots ) I'm not sure how much it's changed since 2014. I think the &quo

I used to use Cockatrice ( https://cockatrice.github.io/ ) to play with friends online. The interface is a far cry from Wizard's MTG Arena, but you do get to build any deck you want for free. Edit: It's been a while

Thanks! I think of it as moving my finger in the same direction as the cursor, which ended up feeling the most natural during typing.

I recently went through the trouble of getting a custom split layout mechanical keyboard machined. I have a write-up/buildlog here: http://www.csun.io/2018/07/16/custom-mechanical-keyboard.htm...

Anyone know of a good service for getting custom large format plots from a machine like this? Looking to make a custom poster in this style but would rather not invest in a whole machine.
