In this article, I review some of the top open source business intelligence (BI) and reporting tools. In economies where the role of big data and open data are ever-increasing, where do we turn in order to have our data analysed and presented in a precise and readable format? This list covers tools which help to solve this problem. Two years ago I wrote about the top three. In this article, I will expand that list with a few more tools that were suggested by our readers.

Watershed can receive data from any xAPI conformant Activity Provider. Many Watershed cards are flexible and you can configure Watershed to display useful visualizations and metrics from almost any xAPI data set. To help you get the most out of your data, we’re working with a number of product vendors to ensure that the data they send is optimized to produce the best possible results in Watershed. We want to help you to configure Watershed cards in the best way possible to display that data.
This guide tells you how to correctly setup up xAPI tracking in Moodle, connect Moodle to Watershed and then configure Watershed to get the best results. As Totara is built on Moodle, this guide works for Totara too.

There are two models of load balancing: transport and application layer. HAProxy is a great TCP load balancer, but it’s lack of SQL awareness effectively limits its ability to address certain scaling issues in distributed database environments. In the open source world, there’s been a few SQL-aware load balancers, namely MySQL Proxy, ProxySQL and MaxScale, but they all seemed to be in beta status and unfit for production use. So we were pretty excited when the MariaDB team released a GA version of MaxScale earlier this year. In this blog, we’ll have a look at MaxScale and see how it compares with HAProxy.

The objective of Let’s Encrypt and the ACME protocol is to make it possible to set up an HTTPS server and have it automatically obtain a browser-trusted certificate, without any human intervention. This is accomplished by running a certificate management agent on the web server.
Let’s Encrypt is a free, automated, and open certificate authority brought to you by the Internet Security Research Group (ISRG). ISRG is a California public benefit corporation, and is recognized by the IRS as a tax-exempt organization under Section 501(c)(3) of the Internal Revenue Code. ISRG’s mission is to reduce financial, technological, and education barriers to secure communication over the Internet.

nginx-vod-module – NGINX-based MP4 Repackager
Features
- On-the-fly repackaging of MP4 files to DASH, HDS, HLS, MSS
- Working modes:
- Local – serve locally accessible files (local disk/NFS mounted)
- Remote – serve files accessible via HTTP using range requests
- Mapped – serve files according to a specification encoded in JSON format. The JSON can pulled from a remote server, or read from a local file
- Adaptive bitrate support
- Playlist support (playing several different media files one after the other) – mapped mode only
- Simulated live support (generating a live stream from MP4 files) – mapped mode only
- Fallback support for file not found in local/mapped modes (useful in multi-datacenter environments)
- Video codecs: H264, H265 (DASH/HLS)
- Audio codecs: AAC
- Audio only/video only files
- Alternative audio renditions – supporting both:
- Generation of manifest with different audio renditions, allowing selection on the client side
- Muxing together audio and video streams from separate files / tracks – provides the ability to serve different audio renditions of a single video, without the need for any special support on the client side.
- Track selection for multi audio/video MP4 files
- Playback rate change – 0.5x up to 2x (requires libavcodec and libavfilter)
- Source file clipping (only from I-Frame to P-frame)
- Support for variable segment lengths – enabling the player to select the optimal bitrate fast, without the overhead of short segments for the whole duration of the video
- Clipping of MP4 files for progressive download playback
- Decryption of CENC-encrypted MP4 files (it is possible to create such files with MP4Box)
- DASH: common encryption (CENC) support
- MSS: PlayReady encryption support
- HLS: Generation of I-frames playlist (EXT-X-I-FRAMES-ONLY)
- HLS: support for AES-128 / SAMPLE-AES encryption
