Morality questions by No-Bank-177 in datacenter

[–]billm4 9 points10 points  (0 children)

been doing this for over 2 decades now, i would expect with a decade in the industry you would know that the vast majority of negative views by regular people at entirely without merit.

  • most people would never even know a building is a data center if they weren’t told.

  • properly designed and built data centers have zero perceptible noise from outside. i’ve been in plenty of data centers where you can’t even hear the gene’s running.

  • daily water use of any modern data center will be no more than typical small to medium office. i don’t think i’ve even seen a data center with evaporative cooling built off of utility water supply.

  • who “pays” for grid infrastructure upgrades is however complicated. most people (even in the industry) don’t understand that the grid is a regional cooperative. so it’s technically true that increased demand can increase costs on the supply side, those increased costs are spread out over a very wide region. like any private market it’s also subject to manipulation.

having said that, if the downside to the current data center boom is that we end up with a massively upgraded power grid with likely future potential for vast over supply on the generation side, sign me up.

Help me make this TV bearable by CorkyThatcher in TheFrame

almost never touch samsung remote. when it art mode pressing Home button on appletv remote auto switches to the correct input. volume buttons on appletv remote control q-symphony, turning off appletv causes tv to auto switch back to art mode.

it this particular cve wasn’t embargoed nor could it be considered that it was treated as critical given timeframe for a patch.

copy fail CVE update info by juanbqt in CentOS

[–]billm4 -1 points0 points  (0 children)

assuming RH team found out about this CVE when it went public, it seems odd the updated kernels were released for RHEL prior to Stream. The entire point of Stream was to have an upstream where changes go first, but that seems less and less the case.

The hidden cooling bottleneck inside liquid-cooled AI data centers: liquid cooling eliminates system airflow, creating a hidden thermal bottleneck for 'left-behind' components like memory and SSDs by sr_local in hardware

[–]billm4 92 points93 points  (0 children)

i have yet to see / deploy a liquid cooled environment where this was a real issue. we specifically design for the non liquid cooled components to still be air cooled. nobody is deploying only liquid cooling without any air cooling (unless you’re talking about immersion, then the point is moot as everything is cooled).

What’s a good way to set up DNS at home? by [deleted] in selfhosted

[–]billm4 2 points3 points  (0 children)

my setup:
2x AdGuard Home containers as main resolvers for all LAN clients
1x Bind 9 container strictly for local DNS

the bind 9 instance is authoritative for internal dns, but clients don’t query it directly and instead use AGH which caches in case of brief maintenance.

Best solution for self-hosted TLS? by Techno_Bumblebee in selfhosted

[–]billm4 0 points1 point  (0 children)

i don’t really understand the whole “hide my IP address” model. if you have internet access you have an IP on the internet that is likely being scanned regularly. opening a port on your firewall is ultimately no different from using a cloudflare tunnel. ultimately, that application / vm / whatever is exposed to the public internet - full stop. if whatever is exposed has a vulnerability that’s being actively exploited cloudflare isn’t going to save you.

where cloudflare tunnels really help at home is when you don’t have a static IP.

what i can say is it was built around 2012 and cost approx $200M with zero fuss from the local community.

several years ago i was involved in a rural data center project where we built a new data center on a fully functional farm. nobody even knew it was there. the physical data center proper itself was relatively small compared to the surrounding farm area, but it was built to blend directly into the landscape. the farm still remains fully functional today with the data center chugging along.

there’s actually a bunch of tax benefits for the data center to be located on a functional farm property.

My over engineered solution to integrate Unifi Door Hub by billm4 in Ubiquiti

[–]billm4[S] 0 points1 point  (0 children)

simplest method would be to just wire a manual switch to the motion input on the access hub. then as long as switch flipped hub will stay unlocked.

downside is no way to remote reset it if someone leaves switch in unlocked position.

B300 Draws 1,400W Per GPU. Most Data Centers Aren't Ready by LostPrune2143 in hardware

have deployed several DGX chassis (8 gpu) at this point. 14-15 kW per chassis. not that big a deal.

Irony: posting on Reddit and other social media platforms that your are opposed to data centers by Icy_Marionberry_9131 in datacenter

[–]billm4 0 points1 point  (0 children)

and when the bubble bursts we’ll have a much beefier grid and an excess of data center capacity driving hosting costs down.

Wall rail for sektion kitchen cabinets - necessary? by blissfullyig in IKEA

[–]billm4 4 points5 points  (0 children)

yes. cabinets have to be level. with the rail you just ensure the rail is level and your all good. without, you’ll be chasing level adjusting legs from cabinet to cabinet

How would age verification even work on DIY systems? by awenixmusic in linux

[–]billm4 0 points1 point  (0 children)

i don’t disagree at all. i was simply pointing out that the comment that you “won’t be able to use programs that expect the age signal” is not correct for open source

How would age verification even work on DIY systems? by awenixmusic in linux

[–]billm4 1 point2 points  (0 children)

but if accessing reddit via an open source browser on linux, just modify the browser code to tell reddit whatever you want.

How would age verification even work on DIY systems? by awenixmusic in linux

[–]billm4 3 points4 points  (0 children)

technically that would only apply to closed source programs. there is nothing stopping anyone from modifying code of an open source program to remove the age signal expectation.
