My angst with the typo, is that I work on CDMA and GSM networks all day. Now, I know that it really should mean CSMA, but can you imagine someone from a different context reading this and wondering how CDMA and Ethernet tie together?
Regardless - less of an issue on a blog post, but Ars normally sets a really high bar for copy editing - odd they let that one get by them.
> That should be CSMA/CD. They had it right earlier and later on, not sure how this reference got by them
It's a one letter typo. The keys are adjacent on the keyboard. Enhance your calm.
