Lit by a pair of 580EXes: one high and slightly to the right on an umbrella, another way off right gelled warm and powered way down, both triggered by an ST-E2. And, of course, the shutter is dragged way out (4 seconds) to pick up the blinky lights.
One of the early sketches about how a cable-based local area network might work, attributed to Ethernet co-inventer Robert Metcalf, father of modern 10 Megabit-per-second networks. Just invent a few routers, switches, security, wireless, management, PCs, servers and you have a local and wide area internet!

Microchip announced the new 24-member PIC32MZ Embedded Connectivity (EC) family of 32-bit MCUs. It provides class-leading performance of 330 DMIPS and 3.28 CoreMarks™/MHz, along with dual-panel, live-update Flash (up to 2 MB), large RAM (512 KB) and the connectivity peripherals—including a 10/100 Ethernet MAC, Hi-Speed USB MAC/PHY (a first for PIC® MCUs) and dual CAN ports—needed to support today’s demanding applications. The PIC32MZ also has class-leading code density that is 30% better than competitors, along with a 28 Msps ADC that offers one of the best throughput rates for 32-bit MCUs. Rounding out this family’s high level of integration is a full-featured hardware crypto engine with a random number generator for high-throughput data encryption/decryption and authentication (e.g., AES, 3DES, SHA, MD5 and HMAC), as well as the first SQI interface on a Microchip MCU and the PIC32’s highest number of serial channels.

I thought the symbology of noose-like ethernet cable bundles in a cubicle farm somewhat poetic.

'Connected’ is the theme for today. I was a bit lazy today so I took an easy option and grabbed a quick and simple shot of part of my 'comms room', which is actually a walk in linen closet :)
When I built my house 8 years ago, I decided to cable most of the rooms with multiple ethernet ports, which can be used for both data and telecommunications to ensure that I would be prepared for a more ‘connected’ future. There is also 2.4 and 5.8 Wireless for phones and ipads.
As time has gone on my home has become more and more ‘connected’ with TVs, Xboxs, Playstations, a 16 TB Server, SONOS Music System, Cameras and other items all connected to the net and home network.
When I was first discussing cabling my home, I was thought to be crazy by some but I have to say it has been one of the smarter decision I made. The ease by which everyone in the house can share and access the net or share files has been a true blessing.
This is my new web server, Its running Fedora 15, with Apache MySQL and its running my blog on andrewgomes.net.
HOBO U30 data loggers enable real-time, remote access to your data via cellular, Wi-Fi, or Ethernet communications, with a direct USB option also available. They can be configured with a wide range of external sensors for measuring weather conditions outdoors, and energy, power, and environmental conditions indoors. These U30 data logging systems have been designed with an industrial-grade and double-weatherproof enclosure to ensure years of reliable operation in a variety of indoor and outdoor environments.

This is a Broadcom BCM5708 Ethernet controller. The server this was pulled from had two identical chips like this, so I only had to open one of them.
It appears to have been designed in 2006 and it uses 4X pcie lanes which you can see on the bottom right (light green blocks).
Here is the best documentation I could find: www.digchip.com/datasheets/parts/datasheet/072/BCM5708-pd...
This server was given to me by a friend and has enough chips to keep me busy for a while :)

The Arduino Ethernet Shield 2 allows an Arduino board to connect to the Internet. It is based on the Wiznet W5100 ethernet chip providing a network (IP) stack capable of both TCP and UDP. The Arduino Ethernet Shield 2 supports up to four simultaneous socket connections. Use the Ethernet library to write sketches which connect to the internet using the shield.
The ethernet shield connects to an Arduino board using long wire-wrap headers which extend through the shield. This keeps the pin layout intact and allows another shield to be stacked on top..
The latest revision of the shield adds a micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the Arduino Duemilanove and Mega (using the Ethernet library coming in Arduino 0019). An SD card library is not yet included in the standard Arduino distribution, but the sdfatlib by Bill Greiman works well. See this tutorial from Adafruit Industries for instructions (thanks Limor!).
The latest revision of the shield also includes a reset controller, to ensure that the W5100 Ethernet module is properly reset on power-up. Previous revisions of the shield were not compatible with the Mega and need to be manually reset after power-up. The original revision of the shield contained a full-size SD card slot; this is not supported.
Arduino communicates with both the W5100 and SD card using the SPI bus (through the ICSP header). This is on digital pins 11, 12, and 13 on the Duemilanove and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used to select the W5100 and pin 4 for the SD card. These pins cannot be used for general i/o. On the Mega, the hardware SS pin, 53, is not used to select either the W5100 or the SD card, but it must be kept as an output or the SPI interface won’t work.
Note that because the W5100 and SD card share the SPI bus, only one can be active at a time. If you are using both peripherals in your program, this should be taken care of by the corresponding libraries. If you’re not using one of the peripherals in your program, however, you’ll need to explicitly deselect it. To do this with the SD card, set pin 4 as an output and write a high to it. For the W5100, set digital pin 10 as a high output.
The shield provides a standard RJ45 ethernet jack.
The reset button on the shield resets both the W5100 and the Arduino board.
