  • CloudInit – Community Help Wiki – cloud-init is the Ubuntu package that handles early initialization of a cloud instance. It is installed in the Ubuntu Cloud Images and also in the official Ubuntu images available on EC2. Some of the things it configures are: setting a default locale setting hostname generate ssh private keys adding ssh keys to user's .ssh/authorized_keys so they can log in setting up ephemeral mount points cloud-init's behavior can be configured via user-data. User-data can be given by the user at instance launch time. This is done via the –user-data or –user-data-file argument to ec2-run-instances
  • Tsunami UDP Protocol – Tsunami UDP Protocol: A fast user-space file transfer protocol that uses TCP control and UDP data for transfer over very high speed long distance networks (≥ 1 Gbps and even 10 GE), designed to provide more throughput than possible with TCP over the same networks. The project is based on original Indiana University 2002 Tsunami source code, but has been significantly improved and extended. As such, large portions of the program today are courtesy by Aalto University Metsähovi Radio Observatory. Includes FTP-like client and server command line applications for normal file transfers. It has additionally been extended for high rate real-time data streaming in eVLBI radio astronomy and geodesy (VSIB, PCEVN DAQ). Licensed under the original IU open source license.

  • 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.

  • ASCII Paint – Enjoy drawing and viewing some crazy ascii art. Output can be in C/C++/Java style comments Assembly comments, or the million other languages that support the # – sign comments.

    Use the buttons to change what your cursor does. Hit whatever key on the keyboard you want to be drawing with.

    If you make something cool, share it! It will be added to our database of ascii art, which will become much more accessible as time goes on. Right now you can only see random Ascii Art, but there will be a voting system shortly.

  • Scapy – Scapy is a powerful interactive packet manipulation program. It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, match requests and replies, and much more. It can easily handle most classical tasks like scanning, tracerouting, probing, unit tests, attacks or network discovery (it can replace hping, 85% of nmap, arpspoof, arp-sk, arping, tcpdump, tethereal, p0f, etc.). It also performs very well at a lot of other specific tasks that most other tools can't handle, like sending invalid frames, injecting your own 802.11 frames, combining technics (VLAN hopping+ARP cache poisoning, VOIP decoding on WEP encrypted channel, …), etc.

  • Top 20+ MySQL Best Practices – Nettuts+ – Database operations often tend to be the main bottleneck for most web applications today. It's not only the DBA's (database administrators) that have to worry about these performance issues. We as programmers need to do our part by structuring tables properly, writing optimized queries and better code. Here are some MySQL optimization techniques for programmers.
  • Stacklet | Create Virtual Images On The Fly – This site will be the home of all development of the stacklet engine, a new way of creating bootable images for virtualization software such as Xen. In addition to hosting the software for creating images, the site will have pre-built images spanning various operating systems, distributions and application niches. This is a large undertaking and hopefully by opening the software we can elicit multiple contributors and contributions.
