Nano-X

I've just rediscovered http://www.microwindows.org/ which is a very lightweight GUI which I think some of you may find very useful on something like a Zero where the standard desktop can eat a bit too much RAM at times!

Re: Will there be a Devuan port for RPi1?

FYI there appear to be images for Pi 1,2 and 3 here: https://files.devuan.org/devuan_jessie/embedded/ and the version for the 3 seems to be 64bit!

Multiple GPUs for AI/number crunching.

There has been some good work done on getting the GPU to do some serious number crunching and I was just wondering if a future version of the Pi could possibly include multiple GPUs for extra processing? We really need to get kids into AI as well as programming and this may be a cheaper more acessib...

Re: Pip or Pip3 on RasPi Zero W is painfully slow

I was just installing Tensorflow onto my Pi3B+ and idly followed the instruction to 'pip3 -V' and it took a full 7 seconds to return the version detail. I tried again with the same result. On my i7 laptop the same command takes a noticeable amount of time to return - less than a second but a definit...

Re: ARM NN and Machine Learning - Boost building

Cancel that - retried the .\b2 link=static cxxflags=-fPIC --with-filesystem --with-test --with-log --with-program_options
and its running OK now! Probably need to add sudo to it to install properly
And I used the shell command I used earlier - hot cpu?

Re: OpenCL on the VideoCore IV!

spinoza1791 Caffe has an openCL port https://github.com/BVLC/caffe/tree/opencl so this may work with that.
I'm busy with other stuff but will try this asap. I'd be interested to see if there are any thermal issues with this.

It seems ARM are about to release some software for speeding up NN stuff on their CPUs so hopefully the RaspberryPis will be included

Building Python3.6.2 with optimizations

If I try configuring python3.6.2 with --enable-optimisations and this causes it to segfault gcc during make.
It seems to build OK with a plain ./configure and make.
The error recommends a full bug report - has anyone also had this?

Re: M$ announces ARM emulator soon

What should be worrying for MS users is why MS cant get their programs to run on ARM with a simple recompile. There's something in deep in a binary that has to be run on Intel as they no longer know what it does otherwise they'd have re-written it in ARM rather than emulate an Intel machine on the A...

Pixel and wandering mouse cursor.

Probably pushing the envelope here: Having had much success on the Zero with PIXEL I thought I'd try in on an old 256MB A (?) and upgraded from raspbian lite with sudo apt-get install raspberrypi-ui-mods and it nearly works. You have to leave it for a while after it comes up and then if you take you...

Thanks for those. Is the pi0 the zero or an earlier pi?
Can we get something from the board itself to tell us what it is to match to the switches?

Re: Compiler options

Is there anywhere there is a list of (raspbian) compiler switches suitable for maximum performance or possible optimisations for each version of the pi? These would be really helpful for a lot of us for getting other packages working.

Re: Does Swap partition help for Rasberry Pi?

Now the Pi3 etc can boot from mass storage devices I would imagine swap will be fun. I have a USB drive on order and will stick a 4G swap on it. I dont anticipate using the swap much but I do do some large jobs from time to time that fail on the Pi.
