Nothing material has changed. Get them to do the job they will be doing, with you. Or, if that would involve proprietary data an exercise that’s as close as possible. They drive, you’re in the background. Some people get nervous, so try to

I used to build quant investment notebooks that had to be deployed in production. Lots of problems with that. Mine were: Notebook cells run out of order, so you often have something that works in a session, but not in a fresh run. Developin

When I was hiring at my old place we set up disposable cloud VMs with a shared screen we could both remote into for interviews. No need for the candidate to install anything, and more responsive and secure than sharing my corporate desktop.

I got frustrated with sites that should just be documents bolting on a pile of javascript libraries, third-party requests etc so I made a standard for sites that are just documents, and wrote a checker for document-only pages. For SSL, the

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 clipping on one side. Then you get a bunch of obvi

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 not interchangeable though. Invention is the initial spark t

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 process - we looked at the possibility of creating a system re

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 calculation and contains a value, similar to a cell in an sprea

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-date or stale as you provide new inputs or change how nodes ar

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 a computation graph that keeps track of state as you u

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 interactively create a graph, where nodes represent inputs or f

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 Problem. Both libraries use graphs to represent dependencies betwe

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 to use graph-based programming, and within an already-

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 offer a birthday card, and maybe a range of other geek products

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 quant, I was shocked by the amount of time code spent executin

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 largest number is 8, then the other two must sum to 15, whi

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

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 impressed. Facebook already has social covered, and I've pretty much

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 double-edged sword for CouchDB. On the one hand, it saves h

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 programmer involved. And that's the killer feature, that more advance

I have used both. I implemented a prototype back-end in CouchDB, and it worked well for this purpose, allowing me to get up and running quickly. But I found that I needed a couple of things that they didn't support - for example, I wanted t

I see slightly differently. It would be nice to be able to have FOSS apps on the iPhone, but I don't think anybody of the parties are acting particularly unreasonably here. I think the FSF is forcing compliance with the spirit of the law. A

The FSF is saying that if the Apple Store wants to distribute a program covered by the GPL, they should comply with the GPL. Which seems reasonable. If you wrote code 10 years ago under the GPL, you retain the copyright, and may distribute
