  • tune apache peformance using mpm prefork module – There could be many reasons why your website performance is poor, one of them can possibly be that Apache is not coping with the load. Below you’ll find ready to consume configuration to make Apache performance better using the Apache MPM prefork module.
  • check-httpd-limits – Check Apache Httpd MPM Config Limits – Google Project Hosting – check_httpd_limits.pl compares the size of running Apache httpd processes, the configured prefork / worker / event MPM limits, and the server's available memory. The script exits with a warning (or error message) if the configured limits exceed the server's available memory. The script does not use any 3rd-party perl modules, unless the –save/days/max command-line options are used, in which case you will need to have the DBD::SQLite module installed. It should work on any UNIX server that provides /proc/meminfo, /proc/*/exe, /proc/*/stat, and /proc/*/statm files. You will probably have to run the script as root for it to read the /proc/*/exe symbolic links.
  • Apache 2.2: Multiple authentication providers « Electricmonk.nl weblog – Since Apache 2.2 multiple authentication providers are now supported. This is nice, since now you can have an LDAP authentication provider with an htpasswd fallback authentication mechanism.
  • lozzd/Nagdash – What is Nagdash? Nagdash is the long awaited replacement of Naglite2. Written in PHP, it uses the Nagios-api, PHP and a sprinkling of jQuery and Bootstrap to provide a full screen, clean Nagios experience which is suitable either for a Dashboard/NOC screen, or simply a simple view to replace the Nagios UI.
  • Naemon Monitoring Suite – Naemon is the new monitoring suite that aims to be faster and more stable, while giving you a clearer view of the state of your network.

  • » Linuxaria – Everything about GNU/Linux and Open source Glances a new system-monitor tool – Glances is a free software (licensed under LGPL) to monitor your GNU/Linux or BSD operating system from a text interface. Glances uses the library libstatgrab to retrieve information from your system and it is developed in Python.

    So another top/htop clone ?

    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.

    [PDF]

  • 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.
