I tried my hand at the sport of curling yesterday. The instructor quickly noted my distinctive personal style comprising strong elements of brute force, awkwardness, and beginner's luck. ;-)

Undefined behaviour in a programming language spec is a good thing because it enables optimisations. Similarly, taking the windscreen wipers off your car is a good thing because it improves aerodynamics.

@vbabka @hrw Anything to improve rocket production, I guess? Maybe Factorio's rockets are too impatient for grace periods. ;-)

@jfbastien @miodvallat Why mess around? Crank it up one more to PDP-12, and enjoy those lovely 12-bit words!!! And 12-bit address space, while you are at it!

@ljs @monsieuricon Being as I come from the Pacific Northwest, when traveling I either get good weather or weather that I a used to. This would be the second option. ;-)

@monsieuricon The river-level gauge is 15cm above normal, but 75cm to go before flood stage. There are a few clogged storm drains. More rain on the way!

I am honored to have been invited to Kernel Recipes. Sorry, no toilet paper this time. You cannot have everything, but who knows? Maybe what will be on offer this time will be better. 😉

@minipli Good point, and a later patch from Vlastimil Babka adds warnings if the slab does not fully free up in reasonable time.

@monsieuricon The story I heard was that English is what you get when Germans attempt to speak French. ;-)

But given a perfectly logically structure language, it would be messed up within two generations. Because messing it up would be seen as being cool.
