It does seem like Intel and Altera are getting close to finalizing the acquisition. The www.altera.com website warns it will be redirected to intel.com on 6/30/2018.
Here's my proposed set of actions:
My rationale is that the altera tag is a good filter for FPGA/CLPD questions, and intel focuses on x86/x64 type offerings. There is also a good argument for merging altera into intel, or making altera a synonym for intel. If someone feels strongly for either of those alternatives (or even doing nothing), please post an answer suggesting that.
