Raspberry Ethernet On WiFi Off

From Top 10 common issues while using raspberry-pi

Ethernet On WiFi Off

By default, when an Ethernet cable is connected to the Raspberry Pi, the Wi-Fi connectivity is disabled. This was implemented probably as a security feature for the Pi to disable routing between the Wi-Fi and the Ethernet port. This action is being managed by a config file named ifplugd which has to be disabled if you want to use the Wi-Fi and Ethernet connections at the same time.

To do this, run;

sudo update-rc networking disable
Or 
sudo apt-get purge ifplugd

You should now be able to use both network options at the same time but do not forget the security loophole this could create as the Pi will behave like a router in this mode.

Subtle hostility

 
I haven’t plugged the M1 MacBook Pro review unit in for three days. Have been using on and off this evening. Battery: 60 percent

Speed aside, this is a truly incredible difference that is causing me to change behavior…

That’s awesome. A little less awesome is the subtle hostility of Apple toward user freedom and Software Libero. As we can read on Linus Torvalds Would Like To Use An M1 Mac For Linux, But..

The new Air would be almost perfect, except for the OS. And I don’t have the time to tinker with it, or the inclination to fight companies that don’t want to help.

Linus Torvalds about porting Linux to Apple’s M1

It’s only a matter of time and we will get it. We already have the low-level but very cheap Pine64 Pro.

Is Apple M1 the new Amiga?

I loved Apple. Not the Apple of DRMs and its golden prison where you can’t really control your hardware; I loved the Apple that loved Software Libero. Then it mutated into a company that crushes people freedoms while smiling.

I like to have control of my hardware. I don’t want to use hardware that treats me like an enemy as DRM-laded machines do or from a company that is actively trying to kill the idea of Software Libero.

So I’ve mixed reactions when reading about Apple M1. I’m happy that they find a way to get so good performances but I fear their “proprietary-ness”, their total-closure toward other OSes. I would change my mind when Apple will help people port Linux, BSD and other free-as-in-freedom operative systems. I fear I will have to wait for a long time as they have been actively doing the opposite in recent years.

Today I’ve read

Why Is Apple’s M1 Chip So Fast?

Real world experience with the new M1 Macs have started ticking in. They are fast. Real fast. But why? What is the magic?

There are a couple of passages that striked me:

  • Instead of adding ever more general-purpose CPU cores, Apple has followed another strategy: They have started adding ever more specialized chips doing a few specialized tasks.
    … and
  • “Unified Memory Architecture”
These features sounds A LOT LIKE the approach of Amiga:
  • Addind specialized chips, Paola, Agnus, Blitter… shall I go on?
  • UMA, accessible to CPU, GPU and other specialized processing units. The very same concept of “Chip memory” in Amiga.

Now I do dearly hope that some company use the same recipe, discovered by Amiga almost 40 years ago.

I hope that the claims made about RISC-V in

are realistic.

Un chip RISC-V promette di demolire Apple M1. Ecco chi c’è dietro e di cosa si tratta

La californiana Micro Magic afferma di aver messo a punto un core basato su ISA RISC-V che non teme confronti, nemmeno l’interessantissimo Apple M1 su base ARM, grazie a frequenze intorno ai 5 GHz e consumi estremamente ridotti.

A me basterebbe che siano anche “solo” all’altezza dell’M1
