An anonymous reader writes "German electronics company Kleinhenz is shipping a network-enabled Linux system built into an RJ-45 Ethernet jack. "Picotux" has a 55MHz ARM processor, 2MB of Flash, 8MB of RAM, a serial port, and five lines of GPIO. It measures 0.75 x 0.75 x 1.4 inches (19 x 19 x 36mm), and weighs 0.64 ounces (18 grams), packaged in a metal housing. A wireless 802.11 version appears to be on the horizon, too. So, if you've ever wanted to network-enable, say, a robot, boombox, or model airplane, this could be the system for you." Is this really the world's smallest? It looks a bit chunkier than a tiny gumstix machine.

Thin Client PC Fits in Wall Socket 205 comments
ukhackster writes "Last year, there was a lot of excitement about a cut-down PC that fitted into a wall socket. Next month, the Jack PC will go on sale in the UK for just £209 ($390)." From the article: "At a low price and using low power, MacLellan believes the device is 'one of the biggest developments in PCs that we have seen' and is one of the 'ever-growing range of thin clients, which are rapidly replacing PCs as a more effective desktop computing solution for modern businesses'. The Jack PC runs Windows CE, is designed to connect to 'any terminal server-based environment' and has Citrix ICA and Microsoft RDP clients built in. It runs Internet Explorer 6.0 to connect to Web-driven applications, and runs an 'up to 500MHz' AMD RISC processor, which the company says is equivalent to a 1.2GHz x86. It can come with up to 64MB of flash memory and 128MB RAM."

Okay, so the gumstix is smaller. But the picotux has built-in eth [gumstix.org].

The picotux is actually smaller than the gumstix. (Score:5, Funny)
Which is smaller - a gumstix or a sheet of paper ? If you say it's the gumstix, then the picotux is smaller.
Otherwise it does not make sense! The german postal service says the picotux is smaller, so the picotux is smaller; but what do shipping fees in Germany, which are paid in Euro, have to do with the size of the gumstix in comparison to the picotux ? And why am I comparing it to mice which are mammals which are rodents of the genus Mus as computer input devices ? It does not make sense.
Therefore you must admit the picotux is smaller.

I could see a use for the wifi+serial setup, you could put this on older serial based nodes and remotely access them. Big market for HVAC when everyone wants them to replace hardware. Our schools here in the Washington state is saving millions by using linux and other technology than going with Honeywell or some other company to rip out the entire system and replace with modern (aka expensive) controls.
A wifi serial setup would be cool, to pop in a router, and then access via my laptop, so I dont have to run a wire when I'm testing or racking it up.
Lots of uses. Very cool idea.

a: For the wired version: Support for Power over Ethernet. This way, separate power isn't needed in many installations.
b: A single USB port for both versions.
Do those both and you now have a general purpose wired and wireless glue for attaching pretty much arbitrary devices to the network.

Dunno what Kleinhenz is shipping, but I'm gussing it's just the DCME with uClinux flashed onto it. Nothing new here.
IIRC, old newsgroup threads when these came out suggest the quantity cost is ~$50/ea, so this product's convenience comes at a bit of a premium.

True, it's no workstation, but still the specs are enough to leak trade secrets across the Internet, and the size is such that the bug may go unnoticed by your employer's IT maintenance department.

Just because you can doesn't mean you should. This is an embedded systems solution, not a desktop replacement. If you play in that world than you knwo 100 euros is quite inexpensive.
The PC is just too big, too fragile, too power-hungry and too unreliable for a lot of tasks where these tiny machines could be used--even if the computational power-to-price ratio is so much larger for the PC. People in the automation world probably remember a few years ago how the PC-based "soft PLC" would reduce costs and replace all those proprietary, expensive traditional PLCs. Never happened and never will because PCs are too general purpose and inefficient. To this day all I've ever used software-based PLCs for is simulation.
For those who are unaware, PLCs, or Programmable Logic Controllers, are esentially purpose-built embedded computer systems used to monitor and control industrial equipment. The bulk of them today are about as powerful as a 286 PC or even less and they cost as much as or more than a high-end PC. Despite that, the hardware and firmware/software in a PLC is designed from the ground up for deterministic, hard-real-time operation and I/O intensive applications. They also do not have processor fans, hard drives and other unreliable mechanical parts.
That is why these tiny Linux machines are so interesting--even if they cannot do as much as a PC or are more expensive. They could be the beginning of a standard, truly open platform for embedded systems. If the processor unit can fit in an RJ45 jack, then in the future we could do away with racks of PLCs and make field equipment control itself. The stuff I can imagine is mind boggling to say the least.
