  • I think your notion of tram accidents is flawed and the conclusions you reach are not supported by evidence.

    Cars are here and are likely to be for the foreseeable future.

    We’re experimenting with things like e-scooters, but our current implementation brings speed differences in close contact, ie. pedestrians vs. scooters, and scooters vs. cars.

    Some countries are doing this separation better than others, for example, the Netherlands seems to have a better handle on this that many others, but that hasn’t always been the case … for context, I used to live there for many years.

    In Perth, more and more areas are enforcing 40 km/h speed zones, but it’s too early to know the full impact of these changes.

    Fundamentally the difference in speed between modes of transport are what causes conflict.

    I also note that distance is not the same in every country, where walking and cycling are viable options in a city like Amsterdam, they’re not in a city like Perth in Western Australia.

    Perth metropolitan area: 21,436 km² Population: 2.12 million Amsterdam metropolitan area: 2,580 km² Population 2.52 million


  • Between the clickbait, YouTube “enhancements”, exploding AI slop videos and the atrocious search facility, the platform is rapidly becoming completely unusable for finding relevant information when you’re looking for answers.

    As an entertainment platform it’s forcing creators to make long form content and making viewers sit through more and more low quality content.

    It’s evolving, but I’m pretty sure it’s heading towards extinction, rather than greatness.





  • As a fully functional adult, I’ve been eyeing off light up shoes for years. So far, all I’ve seen is gimmick shoes you wouldn’t wear for more than an hour, so I make do with fluorescent shoelaces instead.

    This seems like fun, though I’m not sure if I’d be game to walk up a set of stairs on them, perhaps I’m not keen on breaking something when I’d invariably trip and fall.




  • How would you suggest I respond in the future?

    We have a person, claiming that CUPS doesn’t work and they now uninstall it on every installation.

    There is no context, no data, no information that suggests what the issue is, what they tried, when this occurred, on which platform, under which conditions.

    In other words, the user was essentially saying “CUPS sux”.

    Having used Linux as my main system for over 25 years, that sentiment did not match my own experience, does not help anyone, not me, not the user and not the OP who was trying to solve a problem, let alone anyone else reading along.

    I responded accordingly.







  • There’s a common but persistent misconception that Docker is like running a virtual machine. This is understandable but incorrect.

    A better way to think of it is as a security wrapper around an untrusted process.

    If you look at your running processes whilst a container is running, you’ll see the processes inside the container running on your “host” machine - remember, it’s not a host - guest situation.

    There is no relationship between the user inside the container, unless you start mapping the UID and GID.

    The only exception to this is the root user which shares the UID/GID with the actual root user.

    See: https://www.howtogeek.com/devops/why-processes-in-docker-containers-shouldnt-run-as-root/

    Edit: I suspect, but don’t know for sure, that the root user inside the container is actually the same user as the one running the Docker process, which is typically the root user on the “host”.





  • This seems at first glance at least potentially doable.

    Create a website with content that’s only rendered with JavaScript and embed a miner.

    Your challenge is to get the work product back, but you might be able to create dynamically generated URLs that show up in your logs as the work result.

    You’d have to find a way to chunk the work and make it such that the work required is enough to be valuable to you, but not so costly as to stop the crawlers from using your site.

    I suspect that in order for this to actually happen you’d have to have a significant infrastructure to deal with the crawler load, which you could instead be using to do the actual work.

    Ultimately I suspect that this is the software equivalent of a perpetual motion machine, cute in theory, physically impossible.

    Good luck!
