  • APC makes low end offline UPS units, which are cheap garbage.

    They also make line interactive and online ups units, which are decidedly not completely garbage.

    I pick up line interactive APC units from used locations like eBay, and go buy off label replacement batteries. Haven’t had any problems with them so far.

    To date, over the last ~10 years of running a homelab, I have used mainly SMT 1500 units, one was a rack mount. I’ve recently upgraded to an SMX2000. I’ve replaced batteries, but never a UPS, and never any server components due to power issues. I’ve run servers ranging from a Dell PE 2950, to a full c6100 chassis, plus several networking devices, including firewalls, routers and PoE switches. Not a single power related issue with any of them.




  • As IT/network/security, using a well known port for something that’s not what is supposed to run on that port, is inviting all kinds of problems.

    Especially the very well known ones, like ftp, ssh, SMTP, http, HTTPS, etc (to name a few). People make it their mission to find and exploit open FTP systems. I opened up FTP on a system once to the internet as kind of a honeypot, and within a week or so, there was someone uploading data to it.

    No bueno. Don’t use well known ports for things unless the thing that well known port is known for, is what you want to do.



  • I would expect that Gabe is trying to hedge his bets and make the company more of a co-op, where several key figures in the company as well as himself, own the majority, so that there’s accountability in what everyone decides.

    That way if someone’s kid ends up inheriting stock in valve, there’s a way to block them out of major decisions if there’s a need to.

    If that’s indeed what’s happening, then it’s a very long-term play by Gabe. He’s looking so fast ahead, so that long after he’s departed the company, the values that make valve great (and successful) will endure.

    There’s a whole subset of idiots that believe that you need to expose yourself to harmful shit to have a strong immune system. (See: all the people licking toilets and crap during lockdown)

    There’s some credible science to it, in the way that, an immunization is literally putting “harmful” stuff in you to train your immune system. This is known science that I should be able to mostly hand wave around since most people already know this. Immunizations are usually focusing on a key indicator, eg, for COVID, it’s the protein on the outside of the vital cell wall (all the spiky bits in the illustrations) or whatever… I’m no scientist. For other viruses and bacteria, it’s a deactivated version of the virus… It’s essentially “dead” for all intents and purposes. It just resembles the virus so closely that it effectively trains your immune system to recognize it.

    With all that being said, not all bacteria and viruses are something we can develop a natural immunity to, partly because some of them just kill us, partly because there’s something that is preventing it. Again I’m not a scientist.

    Regardless, these idiots think that by exposing yourself to “natural” viruses and bacteria, you can strengthen your immune system. Bluntly, it’s possible to do that, and why the fuck would you want to do it that way? It’s literally a randomized version of a science we already have that’s tried, tested, and proven effective, called immunizations. With immunizations, you get all the benefits of surviving the horrors of some of the most nasty viruses and bacteria out there, without suffering through what those viruses and bacteria are going to do to you.

    The whole thing is stupid.

    If anyone argues about “good” bacteria, tell them to eat yogurt. FFS.
