    Computing

    Anyone else have computers/tech as a hobby?

    I'm in the middle of upgrading from my consumer tower home server to a 4U Supermicro rackmount. With 36 drive bays, two Xeons, and 192GB of RAM, I should have an overkill amount of oomph to play around with.

    Next up is migrating my ZFS pools over, getting my jails up and running, and figuring out how to minimize the decibel level and power draw. Maybe planning on getting some sort of smart home system plus home security video recording set up later.

    I had to laugh at 192 GB of RAM. I guess you're doing some heavy duty data processing?

    I'm not nearly as deep into it as some of my peers in the software industry, but I do have an interest in it. Everything we own is pragmatic and suited to our needs (which isn't much). I do basic programming which both my four year old Lenovo laptop (6gb RAM), and new PC (8gb RAM I believe) can handle. Outside of that we're just browsing and word processing so no great need for a beefy system.

    The PC has an i7 processor and substantial RAM so it's pretty fast, but my laptop is starting to drag. Just waiting for it to die before I buy a new one (when I'll probably upgrade substantially).

    Some of my friends have tried to talk me into building a custom PC in the past, but these people are mostly gamers who care about their specs. Outside of cost-savings, it's easy enough for me to walk into a computer store, and walk out with something that'll do. So I guess you could say I'm not quite a hobbyist, but only because I don't need a lot to get an appropriate ROI.

    Next thing I'll probably do if my employer ever makes working from home the norm is get a nice set of dual monitors on my PC.

    It's a possibility. I've been browsing some r/homelab over at reddit and daydreaming about hypervisors...

    Also, ZFS recommends 1GB RAM per TB of disk space, so it's better to have it than not. They also recommend you keep your pools below 80% of capacity. I'm well over both on my old machine, so I went a little overboard in speccing out the upgrade. I'm going to start with 2 x RaidZ2 6x6TB, and with 36 drive bays the overkill on the RAM was worth it if only for futureproofing the overkill on pool size. The ebay prices on used servers are pretty fantastic though, it wasn't nearly as expensive as it might seem.

    Of course, I don't technically "need" any of this. We are in the hobby forum after all. It just lets me play around writing scripts, setting up systems, and getting the networking to $!@#$#@ work properly. I enjoy fiddling with the settings and getting things running smoothly.

    Even the cost savings aren't that great any more. There are a ton of pre-built systems that are priced really well. Unless you want a weird form factor (my sister and I built a fanless mini-ITX computer for her over the summer - think a full power desktop crammed into a 190x190x60mm case) or want a high end gaming system, you'll only save a bit by building it yourself.

    Next thing I'll probably do if my employer ever makes working from home the norm is get a nice set of dual monitors on my PC.
    Dual monitors are a great upgrade.

    I do some stuff, but I do so with the idea that the only skill set I can develop that I might be able to make money with is... computational/tech stuff.

    So I did that Petrie Illusion thing the other day, which was simple serendipity. I think that if there are good 3d printers, the Petrie illusion bugs could be sold... of course my situation has been deliberately manipulated so that I develop these things without ever getting a return for anything I do, which makes all of my efforts foolish. I don't have access to 3d printers, or the ability to get access to them, because I aligned myself against the corrupt (which was foolish, but I hate them, so no turning back, and yes, I'm well aware of how it looks to say these things, if you're one of those who is comfortable in your complacency to corruption: he's crazy! Of course the system that allows me access to all these things isn't corrupt! Go fuck yourself. ).

    Replication is ongoing...

    I'm successfully resisting (for now) the urge to investigate why the transfer isn't going at the full gigabit bandwidth. There shouldn't be a CPU or hard disk bottleneck...

    I've been known to knock about a couple of lines of code.

    I could fill up 192GB of RAM in a heartbeat.

    guessing you have other devices utilizing the network such that no single device gets the full bandwidth.

    I have been building computers since the largest commercially available hard drive was around 80 MB... and programming them even longer.. .since before hard drives existed (you had a boot floppy disk, and a data floppy disk... and you like it!)
    today, I create individual media files that are larger than that, lol.

    Are you doing some bitcoin mining with all that beef?

    My last build was my VR rig... loving it.

    Probably. I'm still managing not to 'fix it til it's broken'. 70% saturation will have to be good enough.

    I'm trying (for now) to keep my electricity bill on the reasonable side of things. We'll see how that pans out. Drawing 350W with all the disk activity of the replication, was ~260W at idle. I'm estimating that's already going to come out to around $1 per day. Add mining to that and I'd need to work out the ROI.

    0.000143 bitcoins per day to break even.

    Your rig might be able to pull 0.00001 per day.

    you would have to be able to predict future value to know if it would be worth it in the long run.

    I'm guessing maybe not, if you are weighing the electricity bill against it.

    If it were to process in idle time only (such that the full cost of electricity is not overhead), it might be worthwhile, though.

    If you're corrupt you should be able to throttle and increase the speed of your system outside of the standard, posted parameters (and you'll lie about not being able to), so you should get a greater return than, say, a good person.

    Bitcoin, along with every other type of currency, belongs to the cheaters and the gamers who keep the dream alive so the cheaters can prosper without threat (ohh, look, winners, means that my losses are because of luck even though I did the same thing, doy, me too stupid to know the system is corrupt).

    Ohh, I didn't play the game because I've seen evidence that it is corrupt and speak openly about it "you're too negative", and the gamers the cheaters fooled think they won fairly, the ones they bought are cheaters too, so both side with the cheaters and say "you can't win because you didn't play the game". Fucking sell out pieces of shit. Fuck them. Fuck you if you are one.
