The Carbon Tax Is Good for Canadians. Why Axe It?
  • Fat? Not enough to offset the increased cost of ... everything. As I said, the biggest polluters just increase their prices and the rest of us pay. There's no incentive for the big dogs to improve, and the rest of us dont have alternatives.

  • If the logic of copyright/trademark/IP law applied to everything, what's the most peculiar possible implication you can think of for it?
  • Planetary air is free as no one could prove in court that they had any hand in its design or creation.

    However the air in contained facility such as a space station or mars habitat is copy protected. Each inhabitant requires a Microsoft 365 style license renewed annually to breathe. Special areas of the habitat or use cases such as atheltic activities require special temporary licenses.

    Hmmm Brb: writing synopsis.

  • The Carbon Tax Is Good for Canadians. Why Axe It?
  • I have neither option option. All bananas are delivered to my landlocked town via the same truck.

    Bananas are probably a bad example because they are so perishable. They have to be transported in a very controlled environment. Theres no way youre getting bananas from Guatamala to Canada via sailboat and still having them be saleable.

  • The Carbon Tax Is Good for Canadians. Why Axe It?
  • But it doesnt work. Grocery stores raise their prices to cover the carbon tax on deliveries, and the consumers pay more. Its not like we can choose to buy only bananas that were delivered by an electric truck.

  • What's the most useless skill you've mastered, and how did you end up getting so good at it?
  • I can palm a tennis ball, roll it down my arm, bump launch it with my bicep, and catch it. Freaks people out who are standing close as the ball launches right at them, but I've always caught it. Discovered later I could do it with anything that rolls like a microphone.

  • What is something you SHOULD cheap out on?
  • We've been brainwashed by advertising to think that the paste and mouthwash are what matter. They help, yes, but brushing is what matters most. The toothbrush is not just an applicator.

    That said, I personally find Sensodyne to work better than other brand's product for sensitive teeth.

  • The space between the wall and the toilet in my hotel room.

    Fortunately the gentleman at the front desk allowed me to switch rooms. For $200 a night, I'd like to not hit my head on the wall when standing up.

    My new m.2 ssd

    Got a used HP Probook laptop. Just needs a new drive. HP specs say it has an m.2 2280 slot. So that's what I ordered. Guess I needed to look closer.

    edit: Thanks for all the info, guys. Different types of keys are explained here. Gonna have to look for a sketchy no-name brand.

    I have imposter syndrome, both at work and in my relationship.

    The difference that proper air/fuel mixture makes.

    I changed out the burner tubes in the propane grill. The first set of burners I got did not have adjustable air inlets. Ordered some different ones and the difference is surprising.

    They say not to put tomatoes in a fruit salad, but are they using the wrong kind of fruit?

    Are there other types of fruits that could go well with tomatoes in a salad?

    I am 50 years old and I'm about to try Taco Bell for the first time. What should I try first?

    A Taco Bell finally opened up where I live, and we are going to go try it tonight. What should I try and what should I avoid?

    Of course I know I should try another restaurant and avoid Taco Bell, that's too obvious, but what is life without a little Adventure.

    Service account cannot load PHP Class

    Hi all

    I have an Alpine container on Proxmox that we use as a Zabbix Proxy. On it there is a PHP script (no web server). When I ssh in with my normal user account and run the PHP from cli, it works great. When I su to user root (for testing) it works fine. But when I su to user zabbix, I get: Class "PhpOffice\PhpSpreadsheet\Spreadsheet" not found

    This a problem because it will be Zabbix that triggers the script once a day. I get the same error whether zabbix triggers the script, or I trigger it from cli.

    I have other ash, php, and python scripts on the proxy that run just fine when Zabbix triggers them.

    The require statements at the top of the script don't throw an error: require $folder . "/phpSpreadsheet/vendor/autoload.php"; use PhpOffice\PhpSpreadsheet\Spreadsheet; use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

    The error happens farther down when it creates a new spreadsheet in memory: $spreadsheet = new Spreadsheet();

    I had to use Composer to install the phpSpreadsheet library. I was getting a bunch of file & folder permissions errors but I'm certain I've covered that as this is not a file permissions error. I even reran composer as the zabbix user to check for permissions.

    From googling I've found that the zabbix user is a "service account" as opposed to a user account. I used "su zabbix -s /bin/ash" get a cli going so I could test running the script directly. Running env shows that the Zabbix user's HOME directory is "/dev/null" Beyond that I'm not sure what differences there are between the accounts, or what would prevent a php class from loading.

    Any help is welcome. Thanks.
