Thanks everyone. This thread has been a fascinating read for me. Chris

Re: [9fans] Is Plan 9 C "Less Dangerous?"

Thanks Richard, This looks like it fits the bill: open, small, simple. How was it formally verified? This doesn’t seem to need any of the chisel/scala suff, which is great. How can I help with the compiler port? Which fpga board do you recommend? Chris On Sep 6, 2018, at 1:48 PM, Richard

Re: [9fans] plan 9 : any pager?

I like how the pager (page) actually shows a page on the screen with the text you pipe to it. There's some real truth in the name. On Wed, Oct 3, 2018 at 12:34 AM Mayuresh Kathe wrote: > thanks nick. > > On Tue, Oct 02, 2018 at 08:23:47PM -0700, Nick Owens wrote: > > the pager is p(1). > > On

Re: [9fans] Is Plan 9 C "Less Dangerous?"

Thanks everyone. This is pretty much what I expected was the case. I just wanted to confirm my understanding. Plan 9 C was re-engineered with some focus on readable code. Readability is expected to make bugs more apparent, making it less “dangerous.” Linux is so huge and hard to read that even
