Using this project you can add ethernet support on your project powered by LPC2148 (LPC21xx) microcontroller:

In your GSM/3G modem when you type:
It will returns a value (0-31) representing the signal quality:
To convert this number to dBm you need to use this simple formula:
dBm = -113 + N * 2 (where N is the returned value).
This is a getting started to Freescale MC9S08 microcontroller:
This page explains how to interface an Atmega128 with Siemens S65 LCD (using SPI)
This other guy wrote a Linux framebuffer driver to use with this same LCD (German page):
The driver is in the first post (file ls020.zip).
The hwlat_detector module can to detect hardware latencies caused by System Management Interrupt (SMI). SMI is a BIOS features which interrupts any running software (including the kernel) the execute hardware protective routines (for example hw ECC corrections, increasing CPU temperature, etc). Unfortunate SMI routine could be programmed, then some virus can use it to stay running even when you reinstall your computer operating system.
In fact this is not the only SMI drawback, because it interrupts the running software (kernel) it make difficult to use common PC to real time tasks.
To detect this kind of latencies Jon Master developed a module to detect it:
Theoretically you can use OpenOCD to flash LPC2xxx’s programs, but can you have issues using OpenOCD to this purpose, then you can use lpc21isp program as alternative:
If you deleted intentionally your picture or if your SD card get damage, then PhotoRec could save your soul:
This software already save two friends of mine.
