I would be very careful around TEMU I have heard several reports of spurious transactions on the credit cards after buying from TEMU. I'm not sure if it is their website or their payment processor. Keep an eye on your credit card accounts after purchasing from TEMU.

The keyboard that does EVERYTHING – Mountain Everest Max Showcase
-Old-Tom- replied to CPotter's topic in LTT Releases
Still rocking 2 Sidewinder X6's one at work and one at home. Both still going strong after 10 years of daily use. Being able to swap the numpad to the left is actually really handy for data entry. This looks like a reasonable replacement should one of them die. The numpad connector although being a more standard port it doesn't seem super robust if you're going to be switching it from side to side regularly. -
A Northern Lights Blanket would be awesome.

We just leveled up HARDCORE - Fibre Networking Adventure

Yeh the cost difference in price in singlemode v multimode isn't as mush as Linus makes out in the video. the biggest cots difference is in the splicing. we basically only use single mode fibre with 10 km modules at work and the cost is pretty much the same. the main reason there is such a price difference in the enterprise space is just the vendors maintaining their profit margins. i had a quote from HPE recently for a 10 gB, 10 km module for $2k when I could get a module of the same quality for tens of dollars. -
yes it doesn't conduct well but it still convects heat pretty well, it is the same with the liquid phase that's why you need a pump to force convection. there is a decent amount of latent heat with water (2,260 kJ/kg) so if you set things up properly the vapor and liquid will transfer quite a lot of heat around the loop very quickly. Edit: a quick calculation is that you only need to move 77 mg of water per second to move 180 W of heat.

Well using other liquids could work, they would more than likely end up with their loop exploding volatile vapors all though the room. my thoughts are that they are using low pressure water in the loop already as it still has a high heat capacity and you can tune the boiling point depending on the amount of vacuum you pull with the limiting factor being where your pipes collapse (which would be why they are using ribbed pipes in the video). It would be really cool to see this done with hard-line tubing and pull a really good vacuum to get the boiling point down around 20°C. definitely something LMG could try

derr12 also remember that radio is also a 2 way street as a 3 dB antenna at one end and a 20 dB antenna at the other will give you a total link gain of 23 dB. i.e the laptop may not produce a very big signal but the dish as the other end has big ears. we are using a pair of powerbeam PBE-M5-300 to shoot around 10 km from a hill top across to the other side of a township to one of our sites and have had no issues with the link (it's monitored for downtime) and it's been there for well over a year now. it would be interesting to try it directly to a laptop as given the RSSI we have a 3 dB antenna would almost be enough to function though having the extra 22 dB of the second dish means it is super stable. we also operated a 1 km link to a temporary site using a pair of PBE-5AC-400-ISO for about 6 months in an urban/light industrial environment with a 160 MHz channel and had no issues with stability, we even got their quoted 450 Mbps throughput.
-
1.5 km with a clear line of sight you may be ok with just the one (as the dish gives a fair amount of gain in both directions). emphasis on a clear line of sight as of the channel width thing... most laptops etc don't support 80 or 160 MHz channels as they are only used for point to point really. but 20 or 40 MHz channels should serve you just fine. but derr12 is right in that stability could be an issue if you are in a really urban area due to your dish being swamped with all the other APs that it will be able to see but that is kinda just a suck it and see kinda situation.
-
You'll probably need 2 at that distance even with clear line of sight, though with the bigger dishes you may be able to get away with just one.

I get the feeling that they maybe infringing on a trademark here but seeing as it won't make a decent coffee and I cant get it to run Crysis maybe the real NVIDIA aren't to worried
-
I think we just need Linus's shirt from the video on the LTT store to keep us up as 'Sleep Is For Pussies' is no longer available on teespring [sad face]
-
I think 3 of the AP pros was a bit of overkill unless the house is about 10x bigger than they show in the video though I guess that's kinda the idea. I have one AP lite and it covers my whole 1/4 acre property. And it pays to note that you can use one (or more) of these access points as a stand alone solution without having to drop large amounts of cash on ubnt routers and switches
-
Cheers. not that I will ever have the $$ or want to run this sort of setup it may help others that already have a few SLI bridges lying around and were wondering.
-
This is probably a dumb question here but: Being that the big bridge is a kind of a 'dual link' could you use 2 ribbon connectors to gain similar performance?

Rocking an AMD 7970, it'd be nice to finally have some variable refresh rate tech in my rig
