It is simpler if you use the notation [x]_a^b (i.e. with a subscript and a superscript b) to mean x, clipped to the range a to b, and skip writing +/- infinity if you don't intend …

100% agree. People now use “innovate” and “invent” interchangeably. Typically they use the fancier sounding one because they want to impress people with their long words. They are …

Loman author here. Thank you very much for the mention. Amazed that I never heard of Athena or pixie graphs. Our intention with Loman was to create a library scoped for a single pr…

I'm a big fan of Graphviz. My old team created a library called Loman, which we open-sourced, which uses DAGs to represent calculations. Each node represents a part of the calculat…

My team has a similar library called Loman, which we open-sourced. Instead of nodes representing tasks, they represent data, and the library keeps track of which nodes are up-to-da…

The ease of the calculation tree in Excel versus having to keep track of what cells in a notebook you have updated was a large part of why we built and open-sourced Loman [1]. It's…

I had the same trouble with order dependence as notebooks got to a certain size, so my team and I created and open-sourced a library, Loman, to help with that. It allows you to int…

Thanks for the links. I took a look, and I think that the intention is quite different between the libraries. Our library would not directly apply to the Dining Philosophers Proble…

My team has been working on a Python library called Loman that represents computations as graphs. We've open-sourced it [1][2]. One of our aims is to make it as natural as possible…

Hi Jon, Interesting idea. Seems like it'd be a good novelty gift for my family to get me for example. I guess you are already thinking this way, but it seems fairly natural to offe…

I think that one approach that may yield domain-specific improvements would be to add certain numerical routines into the x86 instruction set. When I was working in finance as a qu…

No need to brute-force. It's pretty easy to just eliminate possibilities: The largest number must be larger than 7, else the largest possible sum of the three numbers is 21. If the…

Interesting. Could either of you expand on that? What qualities do you now look for in a client/customer?

How timely. I just started writing a library to scrape data from Hacker News because I wanted to put the posts I'd upvoted in the sidebar of my blog. Link: http://blog.edparcell.co…

I misread that, thinking it was odd that Google would fall to copying Microsoft, and surprising they would copy Windows Me. Reading about the product left me slightly less impresse…

From the article: "CouchDB + Another Layer as Web Server is Redundant". This is very true, and the biggest difference to other databases I've used, NoSQL or not. It ends up being a…

Looks interesting. I develop on Windows, Mac and Linux platforms. My desktop is Windows+Mac, and I'm currently using TortoiseGit on Windows and GitX on Mac, plus the command-line w…

Excel is totally free-form, and for small-scale "databases", it's robust enough (until it isn't). This means the user can do pretty much what they want, without getting a programme…
