This is what I see now when I try to access Google Scholar. Thanks, Google, very useful!

academic.microsoft.com is another service competing with Google Scholar! From (attempting to) claim my profile there, it looks like they put in some manual labor to improve data quality. 🎉

I am troubled by the dominance of Google Scholar as both an academic search engine and as a proxy means for evaluating academic productivity, especially when viewed in light of its lack of transparency and unclear governance. It *certainly* troubled me when Google Scholar randomly blocked my IP address with no discernible recourse. TIL about base-search.net/, some much-needed competition in this space.

It is an embarrassment that the Association for Computing Machinery (but notably *not* SIAM or the AMS, phew!) joined Elsevier and other commercial publishers in trying to torpedo a requirement on open-access publishing of federally funded research. bit.ly/34H1vbz

It appears that I was wrong. I no longer believe that Intel's CPU OpenCL runtime is open-source software. The "build instructions" point back to the binary release to download the runtime. 😡😩 bit.ly/2kky2mO
