This GPT-powered robot chemist designs reactions and makes drugs — on its own
  • Actual real life chemist here. This is not new. We’ve had “chemistry predictors” based on graph theory for decades. All that’s new is that this is AI based. So… potentially less accurate than the current tools.

  • Firms are exploring sodium batteries as an alternative to lithium
  • I’m a PhD candidate in chemistry. I’ve never once seen sodium refer to the salt, sodium chloride. Sodium is the metallic form or the atom.

    However, why sodium, tungsten, lead, antimony, tin, silver, gold, mercury, iron, and potassium and not their Latin forms? Natrium, wolfram, plumbum, stibium, stannum, argentum, aurum, hydrargyrum, Ferrum and kalium? I don’t really know. Mostly it’s just fun trivia for me to tell the undergrads.

    Why does Harley Quinn look like a teenager in various animated series, but in the film she is an adult woman aged 30+?
  • She was a doctor of phycology, so she’s easily late 20s early 30s. Not teenage. Maybe you think she looks young because she’s in shape? I’ve met 40 year olds IRL that have bodies like that. So I dunno about the “looks like a teenager” thing.

    Also remember that in cartoons everyone has fair (smooth) skin until they’re quite old. It’s hard to show subtle signs of aging with cartoon detail. So they’re fair right up until they’re “old”.

  • Why do people look at sunsets?
  • Tell me you live in a city without telling me you live in a city.

    But srsly it’s because it’s beautiful and unique every time. And the sun is below the horizon when we are looking

  • Recent upgrade to my PLEX home server
  • To just get started I'd take a trip to your local thrift store. Some decent old PC tower and a large harddrive is more than enough to get started, play around and get it working. Opt for an intel CPU with "quicksync" if you can as it will do hardware trans coding without a dedicated GPU (like I have).

  • frick.. I cant find the item name at the moment. I do recall though when i sourced it I was looking for a dust resistant cabinet. so their are no grills anywhere except at the top and bottom for 120mm fans. I installed filtered fans to hopefully keep dust to a minimum. If I remember I'll snipe the brand-name later.

  • by power optimization I assume you mean like overclock tuning on the mother boards and adjusting sleep schedules, HDD sleep timing and the like? I admit I haven't done much of that. just stock power and sleep settings.

  • They are "thin" monoprice patch cables. Corey at mactelecom uses them all over the place so I gave them a shot. They dont hold up to a "true" cat 6 spec but as long as they are short (like this, 6") they don't attenuate the signal enough to be noticed.

    Yesterday Evening I replaced my HP z240 that was sitting on a shelf with a Rosewill 2U 15" chassis (center image)

    TheRosewill machine is an AMD 4, Ryzen 5 5600X @3.7Ghz with 6-core/12-threads. 32 GB (4x 8GB) of DDR4 DIMMS. A B550M AORUS ELITE microATX board. With a 1TB NVMe SSD, NVIDIA Quadro P1000 for PLEX transcoding and lastly a SFP+ 10gig network card. I also replaced the stock MOLEX fans with Noctua redux PWM fans.

    The upgrade was primarily to satisfy my OCD and get the "PC on a shelf" replaced with an actual rack mounted computer. The AMD cpu is a bit more powerful than the previous intel i7-7700 and can run the minecraft hosted worlds a bit smoother, and doesn't interfere with PLEX serving or transcoding at all.

    Both the PLEX server and synology data storage server are linked with 10 gig through the 10gig Unifi X16 switch.

    The entire setup is inside of a 18U wall mounted and enclosed rack mount with four 120mm fans for ventilation on the top and bottom.

    Rack explained top to bottom: U1 - Unifi-8p-60W switch for PoE to my two Unifi-IW-AC units.

    U2 - Keystone Patch Panel for inter-rack connections and connections throughout house.

    U3 - Unifi-X16-10G switch (12 SFP+ ports and 4 8P8C ports, all with 10Gig speeds)

    U4 - vented blanking panel with 4x 80mm USB fans for added cooling

    U5 - Unifi Dream Machine Pro with 4TB internal HDD for recording

    U6-8 - Shelf holding my Modem and MoCA adaptor and assorted power bricks

    U9 - Blank panel

    U10-11 - new Rosewill 2U chassis

    U12 - vented blanking panel

    U13-14 - Synology RS1221+

    U15 - blank panel

    U16-17 - Cyberpower UPS

    U18 - PDU

    Opinion - What are your thoughts on password managers? Do you use one? Would you recommend it to others?
  • its fine, but then your locked into firefox.

    you cant use it on say an iPhone with safari, or on chrome, or opera, or brave or edge. or for software licenses, and you cant share passwords with others in a shared vault. All features of other password managers.
