  1. Because it might just take the entire day and 14 restarts for them to finish,
  2. I never even thought about the fact that it was 6 pins instead of 4 or 8, and the fact that it fit like that's where it was supposed to go just reinforced the thought that maybe it was an odd connector on that non-standard power supply he's got. I mean he only had like $50 in the board and CPU together, but still, that's $50 wasted because neither of us took 3 seconds to actually double check the label on the connector. He asked whether he should replace just the CPU or the board and CPU together and I told him since he got them so cheap to just replace them both, that way it doesn't matter if it's the CPU, VRM or both that got cooked. He's only home on weekends and it would be a pain to only order one part and realize the other or both were dead and have to wait another week for the other one to arrive.
  3. Story time. My brother called me up today and asked me to help him upgrade his home server. He has a home server that he uses for his family and himself, but when it comes to technical details, I help him with certain things, so once and a while he'll need help and I don't care a bit to run over and help him out. He had ordered a used Xeon processor, board and some ECC memory to upgrade his home server. We unpack everything, apply thermal paste, attach the CPU cooler, pull the old board out, stick the new board in, hook everything up, plug it in and bam, no life. Not even fan spin. During the installation of the new parts, my brother wanted to help so he sat across from me and when I asked for a cable, he handed it to me. I "did" notice when he handed me the CPU power connector that it was 6 pins instead of 8, but I've seen adapters for such a scenario, and seen boards, even in factory PCs, boot with a smaller adapter connected to it. I simply pointed out that he might want to consider getting an adapter so that his CPU can get the proper amount of power it wants. It never occurred to me to actually check the label on the connector. His kitchen had minimal overhead light, which meant I was working off ambient and a cell phone light, and he had told me it was CPU power, so I just assumed he was right. So after we realize it's not doing anything, we start taking things back apart and double checking things. Move the RAM sticks over into the other channel, try shorting the pins on the JF1 header with my pocket knife to make sure I hadn't misinterpreted the labeling, etc. And when I unplug the CPU power connector I just happened to glance down at it and see that it reads PCIe. A slight panic hit me. The plug FIT, there was no unusual force applied, it was keyed the same as the right 6 pins on the connector and it plugged right in as if that's where it was intended to be, albeit minus two pins, which like I said, I've seen before even in factory built PCs. I quickly fish out the correct CPU power plug and hold it up next to the PCIe power plug and sure enough, the +12V and ground pins are flipped, and the reality of what we just did hits me. We straight up just dead shorted his CPU. I tried plugging in the correct CPU power plug, and while the machine did power on and give us fan spin, it never did POST. No beeps, no video output, nothing, just fan spin and that was it. So, lesson learned, double check the labels coming from the power supply when plugging things in. Apparently just because something fits, doesn't mean that's where it's supposed to go.
  4. Had that same issue today with a work unit. Only the second one I've encountered so far, but every once in a while it seems to find a work unit that it just doesn't like, but rather than skipping it after X number of failed attempts, it just keeps on trying and failing. Here's the last little bit of the log from the previous failed work unit. The "clean exit" line at the bottom is from when I manually stopped the service, not from that work unit succeeding. It's not the end of the world, the solution seems to be to just stop the service, delete the /var/lib/fahclient/work folder and then restart the service so it's forced to start fresh, but it's still kinda strange that FAH isn't catching these itself. I've written a script to make "fixing" the issue a little faster; I may poke around and see if there's some way I can automate a detection of a failure like this that launches my cleanup script automatically instead of relying on me to check in on it every now and then and do it manually.
  5. I let it sit for a while to see if it was going to sort itself out. It never did so I just stopped the service, deleted the /var/lib/fahclient/work folder, then restarted the service. It recreated the folder and requested a different work unit and took off working just fine.
  6. Folding has been running great for a few weeks now. SSH'd in today to check on things and noticed that although the FAHClient service was running, no folding was actually taking place. I noticed in the log it just says "Interrupted" and "Examination of work files indicates 8 consecutive improper terminations of core." The "Interrupted" code 66 supposedly means it's a user initiated interrupt, but I haven't done anything. The service is still running, it just sits there and doesn't do anything though. I've also tried restarting the service, to no avail. Suggestions? I'm considering just renaming/deleting the "work" directory and letting it re-download another project to see if maybe it's just something specific to whatever project I got handed.
  7. That's fine, I was just honestly concerned that I wouldn't be able to produce points fast enough to hit the cutoff in the allotted timeframe, but it appears to be doing just fine after it got through those first couple of WUs,
  8. I thought about adding it to the other PCs in the house, but I ended up not bothering with it so that they could hibernate/sleep without interrupting anything, the fans wouldn't be running on high all the time in the living room, etc.. My little server is getting points faster than I first thought it would, looks like I'll make the cutoff after all, I guess those first couple of work units just weren't worth much.
  9. Depending on how the switch attaches to the hotplate you can probably find an acceptable replacement at your local Radio Shack or auto parts store. Our Radio Shack keeps components like this in stock, and Advance Auto Parts carries all kinds of do-it-yourself electronics components that are aimed at use in cars, but would work just fine in other applications. You can also get them on Amazon as well. Switches just open and complete a circuit when they're toggled, so as long as the conductive materials within the switch can handle whatever load is being passed through them, whether it's a button or a lever or whatever doesn't really matter. One thing I would advise though is that, since the insides of that switch are burnt, you may want to examine further inside the hotplate and make sure other electrical contacts or wires aren't burned as well. Many home appliances like these are woefully under-built and use wiring that is "just" thick enough to carry the load necessary to operate the device, and as a result the electrical components break down over time. Space heaters are also bad for having wiring that is literally the bare minimum necessary to operate the device. This sometimes compounds over time because as contacts corrode or get gummed up with grease and dirt, impedance goes up, which makes the wiring that used to be barely sufficient, not sufficient any more, which generates heat and causes more charring and/or corrosion, which just feeds back into the same cycle until something fails, hopefully in a way that doesn't involve fire. If the switch is charred, there's a reasonable chance other parts are too, and if they are, I would just buy a new hotplate.
  10. I'd like to something like this someday. I might start small and just strap a cheap cell phone to a balloon and have it stream to YouTube or my home server or something, that way if it falls in some hard to get to location or is destroyed in the process (falling into a lake), the footage is still safe. I wonder how far up into the atmosphere cell phone signals actually work. I'm in the US, so I'll have to look up what laws would cover something like that. I believe there are also free radio services like MURS where it "might" be legal to use a radio transmitter for communicating with a device like that without paying for any additional licenses, but I'll have to refresh my memory on the specific rules surround MURS because there might be limits on output power that would hinder its usefulness.
  11. Getting my desk lined out. Cobra 148 GTL with a power supply for the base station radio, police scanner, laptop with an SDR receiver for listening to local radio stations (T'd into the scanner antenna), outside thermometer, an old Realistic Navaho base station radio I'm cleaning up and working on and a few other odds and ends. I've still got some organizing to do, but it's better than it was. I used to have a desktop PC, but I put all the better hardware in the living room HTPC and got a laptop because it takes up a lot less space on my desk and works just fine for most of the things I do on a PC. Anybody else into CB, Ham, Scanners, SDR, etc.?
  12. I have a CB radio base station in the house and a mobile in my truck. I talk to the locals and use it to talk to the wife since it works in more places than the cell phone does around locally. I take my antenna down every few years and wipe all the tree sap and dirt and pollen and crap off it with some rubbing alcohol, then give it a good coat of clear paint to help seal it against water. The antenna has a drain hole in the base of it, but I figure the more water I can keep out of it, the longer the copper wire inside will last. It had been 3 or 4 years since I painted it last and when I took it down I found a crack in the middle section. On top of that, when I was tightening the middle section back down I noticed it started turning inside its base by the tuning coil, so the glue has broken loose. Thing seems to work alright since I was still able to talk to some guys in the next county over, but I'll probably retire and replace it next summer. Hopefully that paint I put on it will keep water from getting into that crack and freezing this winter. For those who don't know, the A99 is a fiberglass antenna, so water aside, years of it flopping in the wind eventually wears on the fiberglass, especially after the factory gel coat wears off.
  13. Oh wow, I missed the dates first time I read the post, I thought it was already underway, Yeah, I may stick it on the kids' PCs and the living room HTPC as well just so they can all be doing something productive with the spare CPU cycles. Only thing I'll probably keep it off is my laptop, cause' it's battery is kinda "meh" as it is.
  14. Doesn't look like I'm going to make the 100k points cutoff with just my old AMD Phenom home server and no GPU. I'll have the number of completed WUs and active days no problem, but I guess the point value of the WUs I'm getting aren't high enough, or I just hadn't been folding for long enough before this event started to have points besides what I'll get from these. Ah well, I'll leave it running anyway, it's not hurting anything, in fact just the opposite is true, it's contributing to something worthwhile. The process priority is lower than the baseline so whenever something else like Plex or Nextcloud or Minecraft Java Edition needs some resources, it takes a back seat to those processes, so the things I use for my personal needs on a daily basis are not affected.
  15. Has it been a thing that long? Holy crap I'm getting old.
