helltone··on Micro C, Part 3: Generating LLVM
I'd love a version of this written in plain C or Python. This is so much better than the Kaleidoscope tutorial. Haskell is a bit hard to grok tho.
helltone··on Dark Reader Malware Clones
wow does this affect Firefox only? (Dark Reader is available for Chrome too)

helltone··on FloatX: A C++ Library for Customized Floating-Point Arithmetic
Interesting, although I believe most neural nets nowadays have moved to use linear (relu) activation, which again removes the need for exponent and would work really well with fixed point.

Here's a reference using 16-bit fixed point neural nets http://ieeexplore.ieee.org/document/7011421/?part=1

helltone··on FloatX: A C++ Library for Customized Floating-Point Arithmetic
I have encountered many real world cases where I needed less precision/range than what float/double had available. But usually I found fixed point was a better solution than reduced precision floats. I wonder what applications are there that can deal with reduced precision but somehow still need the range you get with an exponent?
helltone··on After WeWork, SoftBank’s Startup Bookkeeping Draws Scrutiny
I wonder about Improbable?
helltone··on Cooperative Threading
According to the article, being preempted by the kernel is too expensive because of the context switch userland<>kernel. I wonder if its possible to implement the same preemptive mechanism purely in userland, for example with a timer alarm and a signal handler using swapcontext or similar to achieve better performance?
