MQTT and Arduino Devices – IBM Redbooks – The number of different types of devices that can benefit from MQTT implementations is growing every day. This paper shows how to use MQTT directly from the Arduino platform.
MQTT: MQ Telemetry Transport – MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium. For example, it has been used in sensors communicating to a broker via satellite link, over occasional dial-up connections with healthcare providers, and in a range of home automation and small device scenarios. It is also ideal for mobile applications because of its small size, low power usage, minimised data packets, and efficient distribution of information to one or many receivers (more…)
SoftPerfect Network Scanner: fast and free network scanner – SoftPerfect Network Scanner is a free multi-threaded IP, NetBIOS and SNMP scanner with a modern interface and many advanced features. It is intended for both system administrators and general users interested in computer security. The program pings computers, scans for listening TCP/UDP ports and displays which types of resources are shared on the network (including system and hidden). In addition, it allows you to mount shared folders as network drives, browse them using Windows Explorer, filter the results list and more. SoftPerfect Network Scanner can also check for a user-defined port and report back if one is open. It can also resolve host names and auto-detect your local and external IP range. It supports remote shutdown and Wake-On-LAN.

50+ Killer Apps for Your New Chromebook | Nettuts+ – In celebration of the first wave of Chromebooks being released today, now is a great time to start looking for replacements for the tools you can’t live without on a day to day basis. Code editors, image editors, games? All of these can be replaced! I’ll show you the best choices today.
Howto: Debian Squeeze+Nginx+WordPress – Nginx è uno tra i webserver open source che si sta diffondendo di più tra i sistemisti che ricerchino performance elevate e un consumo di risorse inferiore rispetto ad Apache (ma anche ad alternative “minimaliste” con Lighttpd).
Migrating data – Summary: Migrating or copying data is a frequent task that system administrators carry out often. There are various tools available for these tasks, including cp, tar, and cplv.
Techdocs: Migrating Users from One AIX System to Another AIX System – This document discusses migrating users from one AIX system to another. This does not include transferring the user's personal data or home directories.<br /> The information in this document applies to AIX 5.2 and above.<br /> Since the files involved in the following procedure are flat ASCII files and their format has not changed from V4 to V5, the users can be migrated between systems running the same or different versions of AIX (for example, from V4 to V5).
