  • Sure thing! Yeah the type I cert is an easy choice, same as 609 MVAC. If you’re considering the trade, you might choose universal (I, II, III) to save time. Exam is longer, closed book, and proctored, but not hard.

    Among skilled trades, HVAC is notoriously demanding physically (especially residential, where you’ll spend a lot of time in attics and crawl spaces in hot weather) but consensus on hvac forums is that pay’s good and you’ll never be out of a job as long as you take care of your body.


  • You’ll need to pickup 608 type I certification to legally buy most refrigerants. It’s inexpensive, the exam is open book, and takes an afternoon to complete.

    The “textbook” used is actually a useful reference if you’re just starting out. The material familiarizes you with common terminology, regulations technicians must follow, and the procedural basics for typical jobs, but the emphasis overall is how to handle refrigerants safely and avoid venting them into the atmosphere.



  • I’ve heard this truism my whole life, and glibly repeated it myself at least a few times. But we must acknowledge that it expresses a morally defeatist attitude that poisons the person who actually lives by it.

    Instead you can reconcile kindness by being more observant. Some “good deeds” aren’t actually that good, since their extended effects amount to an unkindness to yourself or those you love.

    For example, let’s say someone asks you to donate to a just cause, or loan them some money in a difficult time. If doing so means your family goes hungry or can’t afford clothes, it might not be such a good deed after all.

    More subtle examples involve your time, such as helping someone by staying late at work, or spending hours listening to someone who really should get professional help instead.

    Ultimately, it’s not true that “no good deed goes unpunished,” but even if it were, it doesn’t matter, because helping people is its own reward.




  • Go camping together. Nothing fancy, just a weekend at a park with a small tent and backpacks.

    Let your team know you’ll be unreachable. Once there, phones off. No working. Just walk and talk, rest and eat, explore your surroundings, focus on what and who is in front of you.

    You may not sleep well on night 1, but you will on night 2, especially if you covered some ground that day. The morning after night 3, however, will be the most well-rested you’ve felt in a some time. The effect carries to subsequent nights, then eventually wears off, but can give you the chance to restructure your days for better sleep in the long term. Use as needed.










  • Maybe yeah. Also got the sense from the strong opinions that this is a preexisting debate, presumably in the context of continuous workloads or cached arrays with minimal spindown intervals. In that context it’s true that rotational disks still often win in energy efficiency and robustness (assuming we’re comparing them to consumer SSDs and not the latest enterprise u.2 stuff that’s rated for continuous work).
