Ryzen




If you decide to venture in this direction then here are some important and not obvious points:

  1. You will need a GPU card. Just about all motherboards come with builtin video outputs and some kind of GPU, however because AMD Ryzen chips have no GPU unlike their common socket AMD APUs (which have a mix of GPU + CPUs) means that there is no GPU capability, hence the mobo graphics sockets will give you just a black screen.
  2. Reset your monitor from the monitor menu. I was trying to figure out why the edges of the screen were cropped and wasted time on a variety of exotic workarounds, only to find that a monitor reset did the trick.
BTW, Ubuntu works fine.

Try Google Web Designer


  1. open terminal:
    ALT+CTL+T to open termainal
  2. download:
    wget https://dl.google.com/linux/direct/google-webdesigner_current_amd64.deb
  3. install:
    sudo dpkg -i google-webdesigner_current_amd64.deb

(You may need to reboot after installation for the app icon to appear in your apps unless you prefer to fight the machine. The first run took a bit to start up, maybe because my wifi connection was delayed after reboot.)

GWD was released 2015 (https://en.wikipedia.org/wiki/Google_Web_Designer). How did we miss it? Possibly because we weren't interested in ads back then.

I had a go.



... and for some fun

On NSW mandatory bike helmet laws

Our mandatory bicycle helmet laws appear out of step with the rest of the World. Initially we were leading with this experiment. On reflection however, it looks more like a misstep that need un-doing.

Our NSW style helmet regulation produces some notable effects: 1) As a barrier to entry, it impedes comparative public health benefits that are gained by incidental exercise from cycling activity, regardless of the intention of any one trip. 2) As over-regulation of transportation, it impedes the very activity that it regulates, consequently producing longer travel times over all by introducing constraints to parallel flow. For example, adding would-be cyclists to at-capacity buses and cars results in straining those systems even more, which cascades further unintended consequences. 3) It discriminates against financially disadvantaged individuals (people in low income and high cost of living) by adding the burden of the average total cost of ownership (helmets, replacements, fines, and lost opportunity), and against the group by way of a high participation rate due to being an attractive low cost mode of transport.

The mandatory helmets in terms of saving lives initially were sold to us as similar to seat belts. But the benefits as it turns out did not outweigh the costs. As a thought experiment, if we extended mandatory helmets to a larger group, say to include pedestrians or drivers, the proposition as a whole may prove more absurd.

Said that, I would choose to wear a helmet on most rides as it serves multiple purposes: such as a hat from the sun, as a night time LED mount, and just to err on the side of caution as a marginal benefit. But then I should not have to ride in fear of a fine, on a remarkably safe bike path, when one of the new bike-share bikes had the helmet stolen.
