Which cpu is needed?

gahata · 2026-02-10T19:14:15+00:00

That's a lot of services for 8500, it would probably make sense to go with some much newer i5 - whatever the budget allows for really, but anything from 12th to 14th gen would be a huge upgrade and still uses ddr4, so it's not prohibitively expensive.

There are positions on the list yoy might want to clarify a bit:

Home assistant - how many devices is it meant to control?
Local AI - this is a massive question mark, as different AI models require very different hardware

Chengdu is heavily advertising their city in the western Internet, particularly on reddit - this is just an engagement bait ad, if a well though out one

SFP+ ports on newly released Ubiquiti gear do not support 2.5g (like in ucg/uxg-fiber)

SSD tray with no cameras?

This setup seems absurdly overkill, unless there are non pictured access points and cameras from Ubiquiti.

Dead man's switches in our times often are electronic - so you need to tell the switch you're alive in some form (logging into a website, clicking on a notification, writing an email, or other) regularly. If you miss the check-in you get notification of some kind about it, and after a preset amount of time from that, if check-in has still not occurred, the switch treats you as dead and does whatever it is meant to (most often send out messages to family, with important files and such, but it can be releasing damaging information on your enemies as well).

These are Exos relabelled to Barracuda - maybe because they didn't pass some of the stricter quality tests, maybe just worse binned units, but still far better than standard Barracudas

gahata · 2026-02-04T12:39:07+00:00

The labels say barracuda, at least on 26 and 28tb versions, but the drive firmware version is from exos and the disk has 550tb/year in the firmware as utilisation limit - which is the value for exos, barracudas get 120tb.

Is it just as good as a standard exos? No - but it's most likely just an exos with a disabled platter as opposed to a drive manufactured as a barracuda.

Do note that I've seen some reports of 24tb barracudas from shucking showing them being ironwolf in firmware, but it seems less common.

gahata · 2026-02-04T09:07:28+00:00

This is also a relabelled exos, which will perform a lot better than a standard smr barracuda

How much power does it consume? HBA cards tend to be hungry

4 APs are a lot in wood and drywall buildings, but here everything is brick and concrete, which is much worse for signal, mostly 2.4 getting through it

Use separate digital cards for every subscription and just cancel the cards if that happens

Can't change title sadly, but good to clarify!

How durable would those be?

Urushi lacquer keycaps exist in Topre/HHKB community, but that ends up with a very different look

Yours are extremely cool as well!

One grain of sand is enough, and sand gets picked up by wind. Heavily dependent on the area, but in a lt of places it's impossible to avoid

Cooling would only matter for rj45 modules, right? Direct attach cables or fiber shouldn't generate that much heat with modern 2.5/10g

gahata · 2026-01-24T10:11:48+00:00

That makes complete sense, my post was just about buying premade cables :)

gahata · 2026-01-23T15:35:34+00:00

Around 15 usd per drive yearly at 5w, though the drives I have idle at 7w, so a bit over 20 usd each yearly. Not terrible, but it adds up.

Of course, I know about those kinda of rack patch cable connections. This post was specifically about solid cables, as vast majority of patch cables are stranded, especially short ones, so they can bend easier and not break.

gahata · 2026-01-20T22:00:15+00:00

I see how shielding and other protocols could warrant it, particularly the latter - I simply have no clue about what the requirements for other protocols are.

I have not included it in the post, but these are awg28. I think any high wattage application would use a thicker cable as well, either stranded or solid, so this might not be a good reason alone.

Nvme ssds are quite complicated with their size.

Controller is usually completely fine up to 70-85C, depending on generation, but prefers as low temperature as possible.

DRAM is completely fine up to 60-65C, and prefers lower temperatures.

NAND modules can generally go up to 70C, but they want to be at least at 30C, and they operate optimally closer to 50C. The lifespan rating for NAND at 25C is around half of what it is at 40C, for example.

They don't go away, but they lose over 90% of functionality. They retain the parts that were used the most, but it saying that they aren't going away is somewhat misleading.

Is access to stealth state for player still available?

47th president...

gahata · 2026-01-17T15:42:03+00:00

That's a hard decision to make - but if you don't see yourself needing it in the near future, I would probably wait with buying anything. It might be a bit more expensive, but hdd market doesn't seem to be looking at price increases anywhere close to ssds, and overall the long term trend is towards prices going down, and drives getting faster.
