If you're looking to setup a GPS-disciplined time-server at home, I highly recommend this writeup: https://austinsnerdythings.com/2025/02/14/revisiting-microse...

In the author's latest post he also sets up a pi as PTP grandmaster: https://austinsnerdythings.com/2025/02/18/nanosecond-accurat...

have a look at this write up:

(not usb though -- uses pps)

Austin of austinsnerdythings.com here - that article does use PPS but there is a different writeup that does use USB that I refer to as my "millisecond accurate" guide - https://austinsnerdythings.com/2021/09/29/millisecond-accura...

P40s are so slept on. 24gb vram for $150.

P40s are no longer $150. On eBay, they're at least $250 from China, or $400 for US sellers

I wrote a rudimentary autopilot in Go that used a Kalman filter to maintain straight and level flight. It was a fun exercise!

And I wrote one in Python to climb/turn as well! And to navigate to any of the built-in X-Plane navaids -

Do you happen to have a link for your HP t6x0 reference? I tried https://www.ebay.com/sch/i.html?_nkw=hp+thin+client+32gb+-(4... and there seemed to be plenty with 32GB of storage but none that I could find with that much RAM
auspiv · 7 months ago
That’s because you have to add the memory yourself.

Just took a quick look- appears t730 is of DDR3 era and may only have a single slot.

t740 definitely has two slots https://www8.hp.com/h20195/v2/GetPDF.aspx/c06393061.pdf

difference might be that a Raspberry Pi consumes < 10W.

An old PC draws easily 5-10 times more energy.

Depending on your location, the yearly cost of running a Pi is around ~10$. The big machine then 50-100$. So energy wise, a small power efficient machine might be more expensive but the running cost could be lower.

mini PCs are < 10W also.

I have a full on Dell Optiplex 3070 (i5-9500, 1x16GB memory, 512GB NVMe) running windows 10 that idles at 8W.

I have a lenovo m92p tiny (i5-3570s, released 2012) that idles at 6W.

I did a ZFS SLOG benchmark last year and the author's conclusion what drive it is (HGST SS300) was one of the test subjects - https://austinsnerdythings.com/2023/01/31/zfs-slog-performan...

That said, the model numbers don't really match up - which is explored a bit in the original post. Don't think a 200GB drive exists in this lineup.

Love HGST drives. Also have a SSD400S 200GB that has 18 PB of endurance.

We tested several models and GPT-4o was the most accurate and makes the most sense for our initial launch

That said: it's 100% our intention to add local models. This is just our v1.

The point is that the verbiage ("To prevent abuse we ask you to sign in before chatting with AI.") implies that only the AI won't work if you don't sign in, not the entire product/site.

> sterile neutrinos

It's funny when one encounters serious real-world discussion on something previously seen as sci-fi technobabble.

In this case, I'm thinking of the Destiny universe, such as this apocalyptic alert from a military AI. [0]

> Multiple distributed ISR assets report a TRANSIENT NEAR EXTRASOLAR EVENT. Event duration ZERO POINT THREE SECONDS. Event footprint includes sterile neutrino scattering and gravity waves. Omnibus analysis detects deep structure information content (nine sigma) and internal teleonomy. No hypothesis on event mechanism (FLAG ACAUSAL). Bootstrap simulation suggests event is DIRECTED and INIMICABLE (convergent q-Bayes/Monte Carlo probability approaches 1). No hypothesis on deep structure encoding (TCC/NP-HARD).

> In the lab that houses the BEST experiment, fish serve as an early warning system about any leaking radiation.

I'm curious how this works, it looks as if there's one central underwater valve and two above-water valves, perhaps supposedly-breathable air is getting bubbled up through the tank?

> SAGE used a tank of 57 metric tons of gallium.

Some napkin-math [egregious mistake corrected] to visualize how much that is, and I get "45 oil drums".

    Line item               Amt Units

double check that math - olympic pool is 50x25x2 meters, or 2500m3. 1 m3 of water is roughly 1 metric ton (1 g/cc = 1 kg/L = 1 t/m3) depending on temperature and such.

57000000g / 5.9 g/cc = 9661017 cc = 9.661m3
