    Happily!

    So, first epoch time. It’s a pretty robust standard, covers many use cases, has few edge cases… but it’s specifically for machine usage, since it’s not human readable and it’s not reversible into the past (pre-1970).

    ISO 8601 (depending on the annum), by the text of the documentation, these are all valid dates:

    • 2007-04-05T14:30
    • 2007-04-05T12:30−02:00
    • 2007-04-05T14:30Z
    • 200704051430
    • 07-04-05T14:30
    • 2007-95T14:30

    Etc.

    RFC 3339 (& RFC 9557, it’s newest modification) is actually a subset of ISO 8601 and is far more prescriptive. For example you must have a timezone designator. You must have a separator between the date and time. You must use a dash between date elements and a colon between time elements. You can easily add standardized subseconds.

    • 2007-04-05T12:30−02:00
    • 2007-04-05 14:30Z

    This means that RFC 3339 is much easier to parse and use by both machines and humans.

    This page (reddit, I know…) has a great summary, and so in the interest of knowledge and attribution I’ll link it: https://www.reddit.com/r/ISO8601/comments/p572xy/rfc_3339_versus_iso_8601/

    This website allows you to more directly compare the two interactively. https://ijmacd.github.io/rfc3339-iso8601/






  • Copying info from another thread:

    Anything ANSI Z87+, sometimes written Z87.1+ (note the plus) rated or CSA Z94.3 rated are ensured to safely withstand a direct high energy strike.

    ANSI Z87 (Z87.1) is a lesser qualification only meant for lighter duty. Use them if you can’t find Z87+ or Z94.3.

    I checked my local hardware stores and while Z87+ is fairly hard to find outside of places that directly supply contractors, CSA Z94.3 ratings are common under $10 but are less loudly marketed. Check the packaging carefully.

    3M is a common and high quality supplier, but anything with an official rating is risking pretty severe penalties from OSHA and commercial liability, so really you should be able to trust them.




  • This makes me so furious.

    Literally every domestic violence study shows a pet being one of the biggest reasons an abused woman stays in a relationship right behind children. And the animal and children are often abuse targets too!

    This will put the US even further behind in one of it’s most shameful measurements, but, hey it might shave a couple thousand dollars off a multi-trillion dollar deficit entirely created by the military industrial complex, so fuck 'em.
