  • I have to use cisco webex, and while the executable is not available for linux, I can say that the web interface is equally outright awful.

    The audio system doesn’t work if you don’t have a microphone (at least on firefox, if the microphone permission is denied, you don’t get to hear anything).
    The video disables itself randomly for bandwidth problems, when nor me nor others are having connection hiccups and then takes its sweet time to come back up.
    There is no way to set the webcam as primary “panel” and sometimes the presenter uses it to share hand-written notes. Combined with the fact that half the time the presenter is also sharing their computer screen, the cam’s vibile area is so tiny the text is unreadable.

    Finally, the mute button gives a false sense of security: the host of the session can force-enable them from their side.
    This feature was highlighted in an incident I escalated with my course to the privacy office at my university.
    A professor activated all the microphones and there was this girl crying her eyes off while arguing with her parents. I hope she never realised what happened, she was already too much shaken to handle being humiliated publicly.

    I at least managed to find a workaround for the microphone: right after the audio transmission has started, if the microphone permission is removed, the stream halts for a second, then continues without any problems. The mic comes on, but after this trick it stays off as intended and no force-enable can do anything about it.





  • In my opinion that’s an honest take on the problem.
    I mean, I’ve seen people link to posts from the same blog multiple times, like the Drew Devault one’s, and the subject was used for a normal discussion, whereas there are users like Laura here that judging from the past posts never really contributed, or did so just with 2 posts that people regarded as interesting, on a total of 100 downvoted below zero.

    Then there are cases like SourceCode.
    He does post a lot of entries from viva64 (which I admit I do not have simpathy for) and cppcast, but he also appears to have a couple of saved posts and moderates three communities.
    While those blogs are a bit spammed for me, he also appears to be an active user, not just a spambot. What take would you get in cases like these?



  • I haven’t done extensive researches on this topic, apart from opening articles from different sites and comparing the content, but I’m pretty sure up to this point anything hydrogen-derived used as fuel doesn’t scale up well when comparing production/storage/transport costs to energy output.

    While, if true, the fact that this powerpaste material is a giant leap forward for secure storage and transport, I’ve seen on a couple other sites that there’s still some concern regarding production.
    Does the yelded energy surpass the amount of work spent while heating and simultaneously compressing the goo?

    I have another doubt as well. If the paste needs water to react and produce energy, how much water is needed?
    Like, would I need a 50 liters tank in an hypotetical goo-powered car to travel a significant distance? Or is the amount of required water so small that it justifies the affirmation made on usage for drones?

    I really hope we can find an alternative to classic fuels, but I would like it to be better than the actual sources, not worse, for the environment.












  • Well, it seems you found a solution to our problems, though I would have liked to see something working in traditional vpns as well!

    I waited for a bunch of more tech savy friends to come online and then we started thinkering.
    We all had our problems at first, not because of zerotier but because of our system configs.

    I, for example had to add broadcast and multicast input rules in iptables (I perfer having iptables block what is not used), then I had to add those routes to the virtual nic. The latter was more of a pain to discover, but fortunately tcpdump helped me find out when packets were travelling or not.

    iptables rules to allow incoming broadcast and multicast on a specific interface

    iptables -A INPUT -i <interface> -m pkttype --pkt-type broadcast -j ACCEPT
    iptables -A INPUT -i <interface> -m pkttype --pkt-type multicast -j ACCEPT
    

    routing rules

    ip route add 224.0.0.0/4 dev <interface>
    ip route add 255.255.255.255/32 dev <interface>
    

    Some of the others had some technical difficulties with the windows network settings: the “fix” which is discussed in the zerotier knowledge base was making their zerotier nic go bonkers.
    It turns out, for some unknown reason, windows was deleting the netmask after the priority was raised for the nic. They just put it back in place.

    Now, since both broadcast and multicast work (tried with tcpdump and multiple games), we tried installing nitroshare to share files as initially wanted and it worked like a charm!
