Translating math into code with examples in Java, Racket, Haskell, Python (2011)

Nice article, I was wondering why Julia wasn't featured considering its support for math syntax. I wondered whether this could have been an old article, but there is no date in the article.

I checked the RSS feed and couldn't find the article in it. I cross-checked the oldest article in the feed with the index of articles on the site, this article seems to be written before Dec 2014. This makes sense for why Julia isn't included.

Don't forget the Internet Archive!

The first version is from Nov. 14: https://web.archive.org/web/20111114185849/http://matt.might... The article index from Nov. 8 does not include the article: https://web.archive.org/web/20111108003034/http://matt.might...

So we can say with confidence that this should have a [2011] tag and was published sometime Nov 8 - Nov 14 in 2011.

It's frustrating when Internet articles don't include publication dates. It's not like it's paper where someone didn't think to record the date. The date certainly exists in the database, filesystem, etc, the author just chooses not to show it, forcing forensics to figure out when it's from.

(I was reading another article from his site yesterday after it was linked on lobste.rs and was also trying to figure out how old it was.)

Why would the date "certainly" exist in the database or filesystem? The file might be one file created in 2001 and modified every date after containing every post in it like a mail spool file. It might be a record in a database table with no date column. If it was a single file, then the creation time could be weeks or months before the publication time, and the modification time could be the last time an edit or tweak was made, rendering both useless for this purpose. I think it's more likely not to have a useful date anywhere unless someone went out of their way to put one in.

(Which they should do, it's useful)

Well, we are fortunate that the author covered four languages. That said, seeing the same in Julia and also Common Lisp would be great. I am coming up on my 36 year anniversary for using Common Lisp, so even though I really love Haskell and Racket, and I am enjoying learning Julia, I would vote for adding CL.

This might be a good community project - the article on github and allow people to do pull requests adding their favorite language.

Thanks for doing the sleuthing on that, I (and surely others) had been wondering about the same :).

I see that there are other comment questioning the same, I saw that only after posting this else I would have added this as comment to it.

That's also supported by the fact that examples are given using Python 2, not Python 3. Not a hard and fast rule, but it's a helpful heuristic.
