ktron Why Lua?

Good point. I was thinking (as jballanc sort of mentioned) of this with regards to composite types. E.g., there is no difference between lists versus hashes versus tuples versus objects, etc. But duly noted for any revised edition :)

ktron Why Lua?

> One other data point: Guile is 5x the size of Lua, in both source and binary forms.

This. We were considering using Guile before we ended up going with Lua and this was actually a big factor for us.

ktron How big are PHP arrays (and values) really?

From the comment:

From the article:

> But if you do want to save memory you could consider using an SplFixedArray for large, static arrays. ... It basically does the same thing, but if you run it, you’ll notice that it uses “only” 5600640 bytes. That’s 56 bytes per element ...

I'm surprised no one has mentioned StExBar -http://tools.tortoisesvn.net/StExBar.html. It is by far one of the most productive, general purpose windows add-on tools that I've ever found (if you call a file explorer add-on "general purpose").

EDIT: fixed formatting url.

ktron Ask HN: Any finance topics you're interesting in learning about?

ktron Ask HN: Any finance topics you're interesting in learning about?

Thanks for the feedback - I'll try to incorporate something along those lines and let you know when it's finished, perhaps you can let me know if you like it.

Maybe it doesn't matter (bc as I understand it, the image is really what notifies you - but this might tip off a hacker if they're perceptive), but would it be better for the zip file to be .zip instead of .gz? I would think that most banks, when interacting with "regular customers" would send zip files instead of gzip files ... maybe I'm wrong?
