Technology Connections recently posted a detailed video about dehumidifiers that's worth watching. But a key takeaway is that on an AC, the hot side is outside (making the inside cool), while in a dehumidifier they are directly next to each other (condensing the moisture).

Without looking into the specifics, my guess is that it's not routing the cold air over the hot side to keep things inside the same temperature.

Related, many small(-ish) bars have a stage for live music on Friday/Saturday. There may not be enough seating for those nights, and there's little/no standing room, so people randomly share tables. From there, you strike up conversation with other fans.

Find the small places where they advertise the bands by name, and make sure they aren't just cover bands. Irish pubs have been lucky for me, but there's another place near me that regularly has jam bands.

It says "No kings". We're allowed to have one.

Just order it direct from AliExpress, just like Trump did

That's part of the strategy. First, go after the small project that can't defend itself. Use that to set a precedent that is harder for the bigger targets to overturn.

I would expect the bigger players to get themselves involved in the defense for exactly that reason.

Of note, Kirsten Gillibrand was on the ballot for a different seat. My guess is that it means something was calling the wrong database table (Senate candidates instead of presidential candidates). This could've been while casting votes, counting votes, or reporting results.

It doesn't make it any less concerning for our democracy, but it's a lot easier to explain how it happened.

Uber and the like have specific warnings about that, too. Of course, you can just ignore them and say you're going to see someone else that's in the ER.

You should take the hint.

Serious question: why would more visibility keep it safer? Israel continues to commit far worse crimes against humanity, very openly, on a daily basis. Why would this be any different?

Just like last time it was reposted, it's from 2022, and is specifically about COVID shortages that no longer apply.

You've already asked yourself what's the worst that can happen. Now ask her what she thinks is the worst that can happen, and what she thinks would actually happen. Do not correct her or interrupt, and only ask probing questions so that you can better understand.

I promise you that her answers are not the same as yours.

You mention spending a lot of time on strange and niche stuff. Don't be ashamed of that; wear it as a badge of honor. You were solving obscure and archaic issues where the answer isn't a Google search away. Chat GPT wouldn't even begin to find the answers.

And, as you should tell potential employers, you can do the same to their obscure, spaghetti-code, internal product loaded with tech debt. Because that's what they always are. You may run into a challenge if their goal is to modernize it instead of just maintaining it, but that just means you focus on understanding it first.

I'm looking to upgrade some of my internal systems to 10 gigabit, and seeing some patchy/conflicting/outdated info. Does anyone have any experience with local fiber? This would be entirely isolated to within my LAN, to enable faster access to my fileserver.

Current existing hardware:

  • MikroTik CSS326-24G-2S+RM, featuring 2 SFP+ ports capable of 10GbE
  • File server with a consumer-grade desktop PC motherboard. I have multiple options for this one going forward, but all will have at least 1 open PCIe x4+ slot
  • This file server already has an LSI SAS x8 card connected to an external DAS
  • Additional consumer-grade desktop PC, also featuring an open PCIe x4 slot.
  • Physical access to run a fiber cable through the ceiling/walls

My primary goal is to have these connected as fast as possible to each other, while also allowing access to the rest of the LAN. I'm reluctant to use Cat6a (which is what these are currently using) due to reports of excessive heat and instability from the SFP+ modules.

As such, I'm willing to run some fiber cables. Here is my current plan, mostly sourced from FS:

  • 2x Supermicro AOC-STGN-i2S / AOC-STGN-i1S (sourced from eBay)
  • 2x Intel E10GSFPSR Compatible 10GBASE-SR SFP+ 850nm 300m DOM Duplex LC/UPC MMF Optical Transceiver Module (FS P/N: SFP-10GSR-85 for the NIC side)
  • 2x Ubiquiti UF-MM-10G Compatible 10GBASE-SR SFP+ 850nm 300m DOM Duplex LC/UPC MMF Optical Transceiver Module (FS P/N: SFP-10GSR-85, for the switch side)
  • 2x 15m (49ft) Fiber Patch Cable, LC UPC to LC UPC, Duplex, 2 Fibers, Multimode (OM4), Riser (OFNR), 2.0mm, Tight-Buffered, Aqua (FS P/N: OM4LCDX)

I know the cards are x8, but it seems that's only needed to max out both ports. I will only be using one port on each card.

Are fiber keystone jacks/couplers (FS P/N: KJ-OM4LCDX) a bad idea?

Am I missing something completely? Are these even compatible with each other? I chose Ubiquti for the switch SFP+ since Mikrotik doesn't vendor-lock, AFAICT.
