Yes and no, an unique thing about glances that I’ve immediately seen is that you can configure thresholds in its configuration file and see the status of your system resources with colors that indicates if everything is fine or not, at a glance.

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.
calligrafia.org » il sito dell’Associazione Calligrafica Italiana – [...] Nel settembre 1991 a Milano, un gruppo di calligrafi fonda l'Associazione calligrafica Italiana. Da allora il programma dell'Associazione è cresciuto con successo anche grazie ai contatti mantenuti con altre associazioni calligrafiche all'estero (in Europa e in America) garantendo così scambi di informazioni e soprattutto la possibilità di avvalersi della collaborazione di insegnanti di riconosciuta competenza. In questi anni l'ACI ha sicuramente ottenuto successi e risultati. Oramai la calligrafia è praticata anche in Italia, sono state organizzate mostre e avviati contatti con biblioteche e scuole[...]
Rajiv’s blog – I was in charge of scaling Dropbox for a while, from roughly 4,000 to 40,000,000 users. For most of that time we had one to three people working on the backend. Here are some suggestions on scaling, particularly in a resource-constrained, fast-growing environment that can’t always afford to do things “the right way” (i.e., any real-world engineering project ;-). If people find this useful, I’ll try to come up with more tips and write a part 2.

Graphvis visualisation of Nagios Config – Nagios Exchange – Graphvis visualisation of complex Nagios configs. I have written a couple of utilities one to walk a nagios config tree and turn it into a perl hash (called nagparse)and another to use that hash converting the tree into a graphvis directed graph (called graphit). These are then brought together with a CGI program called explorenagios that lets you select what parts of the config to graph. If you have a non trivial config then showing it ALL in one graph is not fun!
You can use the two component programs on the command line too – and feed the output into dot (it has been optomised to make nice dot graphs) or one of the other engines like neato if you want to do some hacking of the output options.
It is now useful enough to be worth sharing. Not prefect yet but useful. Surprisingly fast.
