Love mine. I think it looks fine, has a simple display to display a few values, white, and nicely rounded. Basically invisible. I use it to collect the info so I can look at the graphs as needed. Seems like a really nice design. I was i

Pi market ... sure. ARM based SBC not so much. Just get one of the zillion Pi clones that have many advantages like speed, better PCIe, not using USB for storage/net, more ram, better perf/watt, NVMe, etc.

To give some idea my Rk3588 idles somewhere 1.75 to 2.2 watt range, ran it for 17 hours mostly idle except for some apt upgrade/installs on a kill-a-watt to accumulate 0.03 kwh. Using geekbench 5 your J4105 gets 396 single-core and 129

One of the $99 PCs on this thread was 600 cubic inches, the NanoPi R6S is around 10 cubic inches. Here's the link for the $119/$139 deal: https://www.friendlyelec.com/index.php?route=product/product... The sh

Sure, better than a Pi, but better then the rockchip rk3588 system? From a quick look it looks like the MiniPC has half the cores, half the max ram, half the shipped ram, much less I/O performance (SATA @ 400MB/sec vs NVME at 3GB&

They do ship at MSRP, to a large number of corporate partners that embed the Pi in their products. Apparently at the rate of 30M per year. However much like the bitcoin miners who slurped up the GPUs for years, there's precious few Pi

Not sure why there's so much focus on the Pi and it's availability, that's not what the article is about. The article is about the RK3588, it's a substantial upgrade in CPU performance, I/O performance, and network

Fair. Keep in mind that the rk3588 is MUCH more available than the Pi4. The day I looked I found them at 3 stores, but decided to use Amazon with quick shipping instead of the cheaper aliexpress with 2-4 week delay. Keep in mind the rk3

I'm not arguing for the Pi4, I'm arguing for the rk3588. On aliexpress it's $119 with 8GB ram, and $139 with a nice CNC machined metal fanless case. I've seen decent x86's, but matching the spec (case, 8GB ram, 2x2

by sliken 4y ago
That does look reasonable. Seems like a lower spec though, 1/2 the ram, fairly slow CPU, single ethernet (instead of two 2.5G ethernets ports). I do like usb-c for a power supply over whatever custom wall wart+barrel connector. I&#x2

by sliken 4y ago
Dunno, I got a complete working rk3588 with 8GB ram for $139 in a nicely machined metal fanless case, that just needs a modest usb-c power supply. I could have gotten it caseless for $20 less. So it's silent, reasonably fast, and eno

Half as fast would make much more sense. I've seen things like "I'm 40 years young" or a laptop is 10mm thin instead of thick. Half as fast takes it so far though and doesn't make sense.

"you can get much better specced "mini" x86 PC at the cost of slightly more power consumption" ... if you buy used, which doesn't seem like a fair comparison. Generally even the mini PCs are much larger than the rk3

Think of it this way: 1) the closer to the speed of light the bigger difference between your time frame and an external observer's. 2) at the speed of light the universe will age to infinity as you watch 3) inside the event horizon, e

Thus the habbit of carrying a bubble. You can't bubble a bubble, however if you carry just one someone could cut you in half in spite.

Indeed, some 200,000 cars catch fire every year in the USA. Approximately zero of those make the news, unless it's a Tesla. So despite being 11 times less likely to catch fire, if you watch the news you might well conclude that only

There are virus "kits" that allow creating new binaries as often as needed. So for whatever lag time (typically days to weeks) the AV folks have, you just generate something newer. Things are plenty sophisticated to allow VMs, e

Antivirus consumes money, staff time, CPU resources, disk I/O, etc. You can have false positives and false negatives, which can cause even more problems and train people to ignore whatever the antivirus says. The antivirus can cause se

Well there's a couple problems. A) virus companies feed the FUD to make it seem really important and worthwhile B) virus writing folks have figured out how to make an arbitrary number of binaries that the virus checkers don't cat

Apparently there's evidence for increases and decreases in speed of propagation. The difference is really small, on the order of 0.1 degrees per year, which is something like 7 miles at the surface and much less at the core. Some mode

Sure, it's under heavy debate. While the idea or the planet spinning at different speeds weird to think about, the physics do work out. After all not like the atmosphere spins at exactly the same speed as the planet. Why should the

Well keep in mind that it's not the rotation that's stopping, or reversing. So far there's debate, but the data supports the core is spinning 0.1 degrees per year faster or slower. Other researchers think it's changes i

I believe that's inside the chip, much like DDR5. However that doesn't help if there's an error introduced by the packages, pin, board traces, CPU pins, or CPU. Better than nothing, but not full ECC either.
