comcast xfinity speed mountain view ca 2020-07-11

Feel my power! OMG, this poor sob never tasted such wonder. Been stuck at 25 Mbps for the past 20 years now, my comcast xfinity is finally active.

In usa, 25Mbps is considered fast. Faster than that is considered a luxury. see Usa Internet Speed Map

and here's internet speed growth. Basically, 50% faster per year, since 1990. see Internet Speed Growth Rate

R Melts Brains -- An IR for First-Class Environments and Lazy Effectful Arguments

The R programming language combines a number of features considered hard to analyze and implement efficiently: dynamic typing, reflection, lazy evaluation, vectorized primitive types, first-class closures, and extensive use of native code. Additionally, variable scopes are reified at runtime as first-class environments. The combination of these features renders most static program analysis techniques impractical, and thus, compiler optimizations based on them ineffective. We present our work on PIR, an intermediate representation with explicit support for first-class environments and effectful lazy evaluation. We describe two dataflow analyses on PIR: the first enables reasoning about variables and their environments, and the second infers where arguments are evaluated. Leveraging their results, we show how to elide environment creation and inline functions.
