    Old hardware is awesome to reuse most of the time but it’s not nearly as efficient as our hardware today.

    It’s probably good to just properly recycle the old gear and spend $200 on a mini-PC from Amazon that has three times the power all while using less electricity.

    I usually completely tear down old equipment into is raw materials, the best I can. It’s less likely to be shipped off to another country for uncontrolled destruction and I get more money back for the materials.



  • I will echo many others here: It’s going to be rough getting good deliveries. While you are planning on running a proxy, that is basically the same as running an open port where your server is. While it may seem to be a good idea to send email from a random AWS address, it really isn’t. Unless you are behind an IP that is specifically trusted as an email source, your traffic has a higher probability of getting dropped. (Many dynamic IP ranges for home internet connections are marked as invalid or untrusted sources, btw.)

    Additionally, email servers are a hot commodity, especially if they are not blocked (yet) by the larger filter providers. All it takes is one or two reports or a poorly configured firewall/IDS to auto-trigger a submission of your IP address as “bad”. By hot commodity, I mean you are going to get fuck tons of vulnerability scans. It’s not the end of the world, but it’s super annoying.

    If I was operating as a Jr. Security Analyst again and saw and sus traffic coming from your address, I would submit a block and not think twice about it. Hell, most of those types of blocks are automated anyway.

    However, if you do set one up and all is golden, great! It’s worth the experience but something I won’t ever do again. (Yes I did run my own email server before.)



  • Rate limiting only goes so far. 10 requests for a 1 second operation is the same thing as 1 request for a 10 second operation. Any CDN, like CloudFlare, can’t do too much about web requests that are super taxing on the database.

    The bot nets that are doing this can be worse than a hydra. If you block one bot, several more pop up to take over where the other left off. Even worse, the requests that the bots are making are legitimate. If you start throttling the specific requests that are too taxing, you are likely going to cause issues for legitimate users that need the same data.

    Additionally, the number of NAT’ed egress IP addresses are much higher than you might think. Blocking just one IP address could mean that you are blocking thousands of users behind that address.

    Sometimes, the best option is to absorb the traffic and ensure that your application is running extremely efficiently.

    This is a complex problem, for sure.


  • I think there should be an option (unless there is) for mods to turn off (or hide) voting as needed. That might be an effective way to cancel any downvote brigades. Lemmy really doesn’t have the population for mass vote manipulation now, but it will soon enough.

    Hiding all votes can also help mitigate some superficial bias, but not all. I believe that if a person sees a comment with a few dozen downvotes first, they tend not to read the post objectively. After being on Reddit for such a long time (12 years or so), I found that it was super easy to manipulate voting trends if I caught a post or comment at just the right time.

    Hiding only downvotes is just silly though. Some register of public opinion, positive or negative, still has its uses, IMHO.









  • It’s possible that the console is clearing the visible logs when the page gets refreshed after you hit submit. If that is not the case, see if you can trap the HTTP response code after your browser sends the POST. There are a million and one ways this issue could be happening.

    If it gets really bad, use a HTTP(s) man in the middle tool like Fiddler or even OWASP Zap to capture the full exchange. That may give you some more hints.

    It could be the app that you are using, that Lemmy is still going through growing pains with the new flood of traffic or your phone/PC just hates you.

    You are probably going to have to track down the debug logs on whatever device and app you are using to see if there are any post errors.

    Oh. Never trust any web forms on any site, especially if you are typing a big message. I know it’s a pain, but selecting and copying your words is good insurance for long posts.


  • The “midlife crisis” is real. For me, it’s looking for new things to do, cutting out bad habits (drinking) and am trying not to think about how life is actually all downhill from here. I am not going to buy a sports car or anything, but some healthy experimentation with psychedelics does seem to scratch that itch.

    I think I rationalized my fear by understanding just how much shit I have seen and I still have another 30 to 40 years left, which is a good thing.




  • This sent me down a little rabbit hole. I was curious about if science could be considered an ideology but I stopped looking once I found this comparison.

    Hebrews 11:1 - Now faith is confidence in what we hope for and assurance about what we do not see.

    science - noun - the systematic study of the structure and behavior of the physical and natural world through observation, experimentation, and the testing of theories against the evidence obtained.

    That is funny that the bible just straight up tells people to believe in random shit that they hear about it. Hey… A least it is honest in that regard.
