aMSN was based on a previous application named Compu's Messenger (ccmsn), released on September 21, 2001 by Dave Mifsud. Features in this application were quite limited and development seemed to be stopped. Alvaro Iradier made a fork of the development with his own version, aMSN (Alvaro's Messenger). At the time Didimo E. Grimaldo was also working on his own branch of ccMSN until both Alvaro and Didimo heard of each other in a development forum and decided to merge their improvements into one version. The first version of aMSN was released on May 22, 2002 on Sourceforge.

After several successful releases of their join effort, Didimo E. Grimaldo decided to take leave as a developer due to other pressing responsibilities and lack of time. ccMSN/aMSN was in fact the last of several free and open source projects in which Didimo worked.

More developers joined the project, like Philippe G. Khalaf and later Youness Alaoui. Today, the project keeps going thanks to the effort and help of an increasing number of developers, translators, and designers.

aMSN is well known for quickly implementing most of the official client's features, often being the only third-party client that supports them. For example, it is the only client that supports video conferencing on Mac.[5] It has been reviewed by many software-specialized websites.[6][7] Its releases have appeared on several well-known blogs,[8][9][10][11] its developers have been interviewed,[12][13] and it has even appeared on a few TV series internationally.[14][15]

Removal of video call and webcam functionality

With the release of Windows Live Messenger 2009, Microsoft made changes to the protocol used by Windows Live Messenger. These changes included the use of P2P SIP instead of using an external server. As a result of this, the video call function to aMSN was made unusable and was removed from versions 0.98.3 and 0.98.4 of aMSN.[16]

In late 2010, Microsoft released Windows Live Messenger 2011, which removed one-way webcam functionality, meaning that aMSN is left with no practical webcam function.[17]

Autopackage is a free computer package management system aimed at making it simple to create a package that can be installed on all Linux distributions, created by Mike Hearn around 2002.

In August 2010, Listaller and Autopackage announced that the projects will merge.Projects such as aMSN and Inkscape offered an Autopackage installer, and Freecode offered content submitters a field to put the URL of Autopackages. The list of available packages is very limited, and most program versions are obsolete (for example, the most recent Autopackage of GIMP is 2.2.6, even though GIMP is now at version 2.8.2, as of August 2012).

Comparison of instant messaging clients

The current landscape for instant messaging involves cross-platform instant messaging clients that can handle one or multiple protocols so that internet users can communicate with multiple users at the same time. The following tables compare general and technical information for a number of instant messaging clients. See the individual products' articles for further information. External links may lead to extensions that add a feature to a client.

Damn Small Linux

Damn Small Linux (commonly abbreviated DSL) was a computer operating system for the x86 family of personal computers. It is free and open source software under the terms of the GNU GPL and other free and open source licenses. It was designed to run graphical applications on older PC hardware—for example, machines with 486/early Pentium processors and very little memory. DSL is a Live CD with a size of 50 MB. What originally started as an experiment to see how much software could fit in 50 MB eventually became a full-fledged Linux distribution. It can be installed on storage media with small capacities, like bootable business cards, USB flash drives, various memory cards, and Zip drives.

it is now discontinued, but many sites still host the isos for it

Medical-surgical nursing

Medical-surgical nursing is a nursing specialty area concerned with the care of adult patients in a broad range of settings. The Academy of Medical-Surgical Nurses (AMSN) is a specialty nursing organization dedicated to nurturing medical-surgical nurses as they advance their careers. Traditionally, medical-surgical nursing was an entry-level position that most nurses viewed as a stepping stone to specialty areas. Medical-surgical nursing is the largest group of professionals in the field of nursing. Advances in medicine and nursing have resulted in medical-surgical nursing evolving into its own specialty.Many years ago a majority of hospital nurses worked on wards, and everyone was a medical-surgical nurse. Today licensed medical-surgical nurses work in a variety of positions, inpatient clinics, emergency departments, HMO’s, administration, out patient surgical centers, home health care, humanitarian relief work, ambulatory surgical care, and skilled nursing homes. Some military medical-surgical nurses serve on battlefields.

Registered nurses can become certified medical-surgical nurses through the American Nurses Credentialing Center. and also through the Medical-Surgical Nursing Certification Board's (MSNCB) ( Certified Medical-Surgical Registered Nurse (CMSRN) credential.

Medical surgical nursing certification

Medical-surgical nurses must meet certain eligibility requirements along with passing a multiple choice exam may gain certification.The exam takes three hours and it has 150 multiple choice questions

Medical-surgical nursing certification (and recertification) is offered by two organizations in the US:

The Medical-Surgical Nursing Certification Board (MSNCB), a partner of the Academy of Medical-Surgical Nurses (AMSN) an organization that exists to establish credentialing mechanisms for validating proficiency in medical-surgical nursingMSNCB was founded by the Academy of Medical-Surgical Nurses (AMSN), a specialty nursing organization for medical-surgical nurses. MSNCB partners with AMSN to provide an array of programs and services for professional development. The earned credential is Certified Medical-Surgical Registered Nurse (CMSRN).

Microsoft Messenger service

Messenger (formerly MSN Messenger Service, .NET Messenger Service and Windows Live Messenger Service) was an instant messaging and presence system developed by Microsoft in 1999 for use with its MSN Messenger software. It was used by instant messaging clients including Windows 8, Windows Live Messenger, Microsoft Messenger for Mac, and Xbox Live. Third-party clients also connected to the service. It communicated using the Microsoft Notification Protocol, a proprietary instant messaging protocol. The service allowed anyone with a Microsoft account to sign in and communicate in real time with other people who were signed in as well.

In April 2013, Microsoft merged this service into Skype network; existing users were able to sign into Skype with their existing accounts and access their contact list. As part of the merger, Skype instant messaging functionality is now running on the backbone of the former Messenger service.

Nudge (instant messaging)

Nudge, also known as buzz, is a feature of instant messaging software used to get the attention of another user, for example, by shaking the conversation window or playing a sound.

Video4Linux, V4L for short, is a collection of device drivers and an API for supporting realtime video capture on Linux systems. It supports many USB webcams, TV tuners, and related devices, standardizing their output, so programmers can easily add video support to their applications. MythTV, tvtime and TVHeadend are typical applications that use the V4L framework.

Video4Linux was named after Video for Windows (which is sometimes abbreviated "V4W"), but is not technically related to it.While Video4Linux is only available on Linux, there is a compatibility layer available for FreeBSD called Video4BSD. This provides a way for many programs that depend on V4L to also compile and run on the FreeBSD operating system.
