The Network File System (NFS) Version 4 is a distributed file system similar to previous versions of NFS in its straightforward design, simplified error recovery, and independence of transport protocols and operating systems for file access in a heterogeneous network.
NFS, was developed by Sun Microsystems to provide distributed transparent file access in a heterogeneous network. It achieves this by being relatively simple in design and not relying too heavily on any particular file system model.
This presentation is based on the paper of “The NFS Version 4 Protocol” written by Brian Pawlowski, Spencer Shepler, Carl Beame, Brent Callaghan, Michael Eisler, David Noveck, David Robinson and Robert Thurlow.
IPsec provides the capability to secure communications across a LAN, across private and public WANs, and across the Internet. Examples of its use include:
Secure branch office connectivity over the Internet
Secure remote access over the Internet
Establishing extranet and intranet connectivity with partners
Enhancing electronic commerce security

MongoDB Days Silicon Valley: Using MongoDB with Adobe AEM CommunitiesMongoDB
Presented by Kevin Nennig, AEM Technical Instructor, Adobe
Experience level: Introductory
In Adobe Experience Manager 6.1, a new approach has been taken for user generated content (UGC) for better security, higher availability, and ease of use for community members and administrators. The Social Resource Provider API for AEM Communities can be implemented 3 different ways to create a UGC cloud, two of which use a MongoDB backend. Utilizing MongoDB, companies can implement an on prem UGC common store with a Mongo and a Solr server. UCG is then stored and accessed from this UGC cloud. In this session we’ll explore the Social Resource Provider framework and implement the Mongo Social Resource Provider (MSRP) for AEM Communities.
This presentation was given at the London Nutanix user group (NUG) on Oct 26 by Grant Friend. If you would like to join a NUG, you can find more information here http://bit.ly/NTNXUG - Hope to see you at a community meeting!
VMware Workstation is a type-2 hypervisor software application that enables users to create and run virtual machines on their desktop or laptop computers. It allows multiple operating systems (OS) to run on a single physical machine, each with its own virtual hardware and system resources such as CPU, memory, storage, and network adapters.
With VMware Workstation, users can create, configure, and manage multiple virtual machines, including different OSes, applications, and tools. It also provides features such as drag-and-drop functionality, seamless integration with the host operating system, and support for a wide range of hardware devices.
VMware Workstation is a popular choice among developers, IT professionals, and power users who need to test software, run legacy applications, or simulate complex network environments. It is available for Windows and Linux operating systems and offers a 30-day free trial.
Multimedia data and information must be stored in a disk file using formats similar to image file formats. Multimedia formats, however, are much more complex than most other file formats because of the wide variety of data they must store. Such data includes text, image data, audio and video data, computer animations, and other forms of binary data, such as Musical Instrument Digital Interface (MIDI), control information, and graphical fonts. (See the "MIDI Standard" section later in this chapter.) Typical multimedia formats do not define new methods for storing these types of data. Instead, they offer the ability to store data in one or more existing data formats that are already in general use.
For example, a multimedia format may allow text to be stored as PostScript or Rich Text Format (RTF) data rather than in conventional ASCII plain-text format. Still-image bitmap data may be stored as BMP or TIFF files rather than as raw bitmaps. Similarly, audio, video, and animation data can be stored using industry-recognized formats specified as being supported by that multimedia file format.
This presentation is devoted to the architecture of streaming services, special features of adaptive streaming, benefits and disadvantages of various streaming technologies and specific issues of media streaming apps development.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features

– To: Digital (e.g. Internet)
• Authoring: Copyleft/Copyright
• Protecting: Encrypted or at least secured
3. A&V Digital Processing
• Hardware & Software:
– Open vs. Propietary
• Encoding:
– Audio / Video (Capture/Record)
– Analog/Digital (Compression / Lossless / Lossy)
• Transcode:
– Analog <-> Digital (Format)
– Hardware / CPU / GCPU
• Transmuxe:
– Digital A&V Format Conversion (a.k.a Transcode)
• Stream (Digital *Cast):
– Server / Client (Playback).
– Live Stream => Live (Re)Streaming (LS)

7. Streaming Protocols
– Internet Based (IP):
• UDP (Not Connection Oriented / Datagram)
– Real Time Streaming Protocol (RTSP) is a network control protocol designed by
RealNetworks (1996) for use in entertainment and communications systems to
establishing and controlling media sessions between end points
• TCP (Connection Oriented / Packet)
– RTMP (Real Time Messaging Protocol) created by Macromedia (Adobe) for
Internet stream of Flash Video (FLV ~ H.263 + MP3). Released for public use in 2005
– Web Real Time Communication (WebRTC) new project for native zero install any
browser open and free video streaming standart for Internet, started in 2011.
Supported by all major browsers Chrome, Firefox, Opera, Android & iOS
• Others:
– MPEG-2 Transport Stream (MPEG-TS) is a standard digital container format for
transmission and storage of audio, video, and Program and System Information
Protocol (PSIP) data.[3] It is used in broadcast systems such as Digital Video
Broadcasting (DVB), ATSC and IPTV
8. Streaming Protocols
– Web Based (HTTP):
• Progressive Download (Pseudostreaming): web server based method for seek and
buffering, Apache/Lighthttpd (mod_[h264|flvx]), Nginx (http_[mp4|flvx]_module,
Nimble Streamer and many others).
– HTML 5: Most of browsers are comming to support open & standart «video
audio» combos: WAVE PCM, MP4 H.264 (AAC o MP3), WebM, Ogg Theora
Vorbis, Ogg Opus.
• HTTP Live Streaming (HLS) created by Apple for streaming audio to its iPhone, iPad,
Mac, Apple TV devices (also PC) since 2009.
– Apple VOD formats takes video file from MPEG-4 / QuickTime MOV to H.264
Compression and audio files to AAC or MP3 compression.
– Apple LS formats uses MPEG-2 transport streams carrying H.264 video, AAC or
MP3 audio.
• Dynamic Adaptive Streaming over HTTP (mpeg-DASH) developed by MPEG
(Moving Picture Expert Group) is the ISO/IEC 23009-1:2012[14[ since April 2012.
9. Streaming Protocols
– Web Based (HTTP):
• HTTP Dynamic Streaming (HDS): created by Adobe as part of
Flash (>=10.1) using MP4 Fragment Format (ISO/IEC 14496-
12:2008) that allows fetch smaller portions of media than
HLS. Allows DRM on live or VOD. Improve RTMP Dynamic
Streaming (Flash >=6) and HTTP Progresive Download (Flash
>=7) from Adobe.
• Microsoft Smooth Streaming (MSS): is a pseudo-streaming
implementation introduced in 2008 by Microsoft as part of
their Silverlight architecture. Microsoft and Akamai works
on «www.smoothHD.com».
10. Streaming Protocols
–Web Based (HTTP):
• SHOUTcast cross-platform proprietary freeware for
streaming media (audio/MP3) over the Internet
developed by Nullsoft but owned by AOL.
• IceCast: cross-platform free software (GPLv2) mantained
by the Xiph.Org (www.icecast.org) for streaming the
following streams: Ogg (Vorbis, Speex, Flac, Theora),
Opus, WebM and MP3.
11. Audio & Video Formats
• They can’t be written neither this slide nor
this document…
18. Pseudo Streaming
• File formats: mp3, mp4, flv, oga, ogv, wav, webm, mkv
• Optimization: flash time marks seek, HTTP range header
• Packet loss retransmission: which is not available on live streaming
Keyframes
Play Back & Forward
Range Download
Only HTTP
Buffered
Current Playing
Lineal Download
FTP or HTTP
22. HLS Benefits & Tips
• HLS is not A&V is only the delivery way
• Supports (client-driven) adaptive bitrate
• Better experience:
– No “partial play”
– No “Complete download”
• Delivered over standard HTTP, so zero firewall
blocking policies.
• Developer and devices easy integration with
simple, text-based manifest format.
• No proprietary streaming servers required, so
more people streaming & playing back.
23. HLS Benefits & Tips
• User are dropping major vendors with
proprietary standards (i.e. Flash).
• Major browsers no longer support plugins
(zero install, plug & play, security,
licensing).
• HLS video is now supported on multicast
(RAMP Multicast Engine Startup).
