You ever recover a lost memory?
  • Happens fairly often to me with very specific smells. I’ll get a whiff of something and it will smell familiar but it’ll confuse me for like an hour, and then all of a sudden I’ll remember what it’s from

  • Boeing's Starliner has 5 'small' helium leaks as astronauts' ISS mission is extended: NASA
  • lol, I worked on a project at my company that sent a box with various instruments up to space sometime in February… but it’s waiting on something that’s on the Starliner before it can be unboxed and used, so now it’s just been sitting for 4 months and will continue to do so for god-knows-how-long

  • I've been asked to share my messy and disorganized collection, so here it is - feel free to point and laugh ;)
  • Love it!! Thanks for posting :) it’s just about as “disorganized” as my own collection, if not less so - it’s tough to keep six bajillion plants all in check. I wish I lived somewhere warm enough to leave my plants outside all year!

  • Why don't electric car manufacurers put solar panels on the car roofs?
  • You’re absolutely right - still absurdly shaped pancakes and they can’t reach highway speeds when powered on solar power alone. They do reach road speeds nowadays but they’re allowed to charge during and after race time (regulations are pretty confusing). I was on a solar car team a few years back.

  • Why don't electric car manufacurers put solar panels on the car roofs?
  • Doesn’t provide enough power for the cost of the cells, plus having to clean and upkeep them. And the more material you cover them with (to protect them; solar cells are INCREDIBLY fragile), the less efficient they are. I was on a solar car team in college and the cells are so fragile that to clean them, we had to use new microfiber cloths every time. Any dust would scratch and ruin them (which made it quite tough when I drove across the outback in the thing). We kept our cells completely uncovered because we needed maximum efficiency - but even with a super light carbon fiber solar car that’s got very minimal tire contact patches, specialized tires from Bridgestone, and a very aerodynamic shape (plus no amenities like A/C), I think our car could sustain something like 10-15 km/h on a perfectly sunny day in the middle of the outback. It just doesn’t add enough on a huge, heavy EV

  • Went to Tokyo Cactus and Succulent Grand Bazaar today and didn't come home empty handed ;)
  • Love them! I always look forward to your posts :) I’d love to see pics of your collection - seems like it’s quite large! …and maybe some pics of the Tokyo succulents show(s) - have always wondered what a succulent show looks like and we don’t really have many in Minnesota :/

  • They'd still both rather use C++ than each other though
  • I started with C++ too, and then ended up finding a job writing firmware pretty much all in C. There really hasn’t been anything we’ve run into that’s made us consider switching to C++; being able to (and needing to) have complete control over your memory means you can do some pretty fancy stuff with the tiny amounts of memory on our ASICs.

    We’ve been eyeballing switching to rust a little bit, but really only for other applications; the root of our main code base is over 25 years old at this point and a rewrite would take a Herculean effort.

  • New to home networking - Need some security advice!

    I’m very new to home networking. I’m not new to computers (hardware or software) - but for whatever reason, anything network-related has always been an enigma to me.

    That said - I just got a new (to me) server. It’s a beefy one (made a post about it in another community). And so I figured why not just start playing around with Proxmox, learning some new things and spinning up a bunch of random VMs and whatnot.

    I figured the first step would be to set up something such that I can connect to my computers from anywhere - and I’ve already done so. For that, I used Tailscale. But my question, I suppose, is now that my computers are on the internet (as in, for real on the internet, through Tailscale) - are there security precautions I have to take now and things I need to be more concerned about? Do I have to set up my own special firewall to make sure I don’t get hacked or something? I am honestly pretty clueless in that whole domain. So… ELI5 what I have to do, security-wise. Any and all help is welcomed and appreciated.

    Bonus question: beefy server is beefy (yes yes, lots of power consumption, I’ve already come to terms with it. About 200W idle and should run me ~$40/mo.). Dual 18-core E5-2699 v3s. 768GB of RAM. More SSD storage in both boot drives and storage drives than the average human would use in a thousand years (SAS, SATA, & NVMe). I asked this over on c/piracy - what should I do with it? I’ve put Proxmox on it, and as said above, plan on learning things about VM hosting and different operating systems and whatnot. I’m also planning on hosting my own Jellyfin server. But… what else? Does anyone have any good ideas for any (non-GPU-intensive) things I can do with the server? Anything and everything welcome, lol - I wanna have fun with this thing!

    TIA for the responses :)

    What to do with a beefy server?

    Alright, this may be a bit of a loaded question. But I figured it may provide good insight to both myself and to others. I just came into a pretty beefy server - dual Xeon E5 2699 v3’s (18 cores each), 768 gigs of RAM. Ten front drive bays, 6 of which have 7.68T NVMes and 4 of which have 15.36T SAS drives. I’m thinking the NVMe drives will go into a single RAID 5 or 6 (thoughts?), and the 15360s I plan to use for more sensitive stuff so I’m planning dual RAID 1’s there. Boot drives will be a hardware RAID 1 of dual 1920G SATA SSDs. So again… pretty beefy. I believe this server would cost me ~$100/month to run, although I may try something where I keep it off 6/7 days of the week and only turn it on if I need it otherwise, I’m not sure yet. Thoughts on that are welcome too.

    All of that said. I’ve got the power & the storage for some pretty neat projects. But I’ve not delved into anything of this nature before. I’ve heard of Plex, I’ve heard of Jellyfin, but I don’t really know what it all means past that. And I think it would be pretty neat to be able to dump some streaming service subscriptions and make up for a bit of the coin I’d be dumping to power this thing (may also host a Minecraft server with it, lol).

    I’m very familiar with Linux/console, so that’s not really an issue. I’m erring towards either Arch or Ubuntu (fight me, I like both).

    Thoughts? Ideas? I figured this was a good community to post this in but can remove if it isn’t.
