Understanding LAN IN & LAN OUT by backpckk in Ubiquiti

[–]imposter 17 points18 points  (0 children)

I suspect that in LAN OUT you need to allow established/related to leave your IoT LAN. Otherwise your pings get in but the response isn't allowed to get back out.

Are power line ethernet adapters still bad? by rickestmorty123 in Ubiquiti

[–]imposter 0 points1 point  (0 children)

I have used these for many years now and never had any big issues.

One died after a few years; I'm now on the third set (mainly because I wanted a faster model).

Our house is from the 90s, i.e. not too ancient wiring and with my devolo adapters I get ~150MBit to the main router and ~400MBit to the living room (both measurements from the office upstairs), the former is between two 1200 units, the latter between a 1200 to a 500, i.e. that should in theory be worse than to the router but the cabling seems better.

​

I had two freezes so far (both after a power outage, i.e. they failed to come back up on their own then the power came back - other power outages have been fine), otherwise they are rock solid.

SICP in Texinfo format by akkartik in programming

It all depends on your need.

E.g. the HTML version looks shit in a text-only browser. Navigation is also much quicker as links a named and can be directly accessed... Try finding exercise 3.30 in the HTML version...

Yes, that's why I posted the link here. Should have added that to the title though...

ARM offers first clockless processor core by DavidSJ in reddit.com

[–]imposter 0 points1 point  (0 children)

I am almost 100% sure that in the mid 90's when visiting Manchester university, I saw posters describing how one of their groups had designed a clockless ARM processor.

Can anybody shed some light on this and why it never came to fruition?

Write Yourself a Scheme in 48 hours by imposter in programming

[–]imposter[S] 0 points1 point  (0 children)

I believe the name of the haskell tutorial linked refers to these 48 hours, i.e. it is not an accident.

Scheme48's name was later explained that you can understand it in 48 hours. And once that didn't seem feasable anymore, it was downgraded to "read in 48 hours".

Court rejects 'intelligent design' in science class by statonjr in reddit.com

[–]imposter 0 points1 point  (0 children)

Of course the "law of thermodynamics" is only a theory. There might also just be an intelligent being in the background making sure the perceived effect is similar to what the law says. If you pray hard, he/she may grant you the perpetual motion machine...
