Things will never be the same again after the dust settles. And yes, Iâm talking about Linux. As I write this, most of the world is in lockdown due to COVID-19. Itâs hard to say how things will look when this is over (it will be over, right?), but one thing is for sure: the world is no longer the same. Itâs a weird feeling: itâs as if we ended 2019 in one planet and started 2020 in another. While

Summary: The Safe library has lots of small functions, none of which have INLINE pragmas on them. The lack of INLINE pragmas probably has no effect on the optimisation. I was recently asked a question about the Safe library: I was wondering why you didn't use any INLINE pragmas in the Safe library. I'm not a Haskell expert yet, but I've noticed that in many other libraries most one-liners are anno
Bridging cultures that have often been distant, Julia combines expertise from the diverse fields of computer science and computational science to create a new approach to numerical computing. Julia is designed to be easy and fast. Julia questions notions generally held as "laws of nature" by practitioners of numerical computing: 1. High-level dynamic programs have to be slow. 2. One must prototype
Thereâs a great MSR demo from 2012 that shows the effect of latency on the experience of using a tablet. If you donât want to watch the three minute video, they basically created a device which could simulate arbitrary latencies down to a fraction of a millisecond. At 100ms (1/10th of a second), which is typical of consumer tablets, the experience is terrible. At 10ms (1/100th of a second), the la
