Missionary is a reactive dataflow programming toolkit providing referentially transparent operators for lazy continuous signals, eager discrete streams, and IO actions. Missionary aims to improve over state-of-the-art reactive systems, it can be used as a general-purpose asynchronous programming toolkit but also as a basis for event streaming and incremental computations.
PostgreSQL High Availability Options: Why PostgreSQL High Availability Matters and How to Achieve It
A Guide to PostgreSQL High Availability
Ensuring your application can handle failures and outages is crucial, and the availability of your application is only as good as the availability of your PostgreSQL instance. With that in mind, you may be wondering which PostgreSQL high availability (HA) deployment option is best for your application.
Let’s review several popular solutions that increase the high availability of PostgreSQL deployments and, as a result, the availability overall of your application. Why several and not one? Well, there’s no silver bullet or one-size-fits-all solution when it comes to high availability and PostgreSQL. So, walk through the options for a highly available deployment of PostgreSQL and then you can make a choice that fits your use case.
RTK2go® is a community NTRIP Caster created to allow you to publish your GNSS correction streams for others to use with their NTRIP Clients. It is built using the same Pro edition of the SNIP Caster you can find on the use-SNIP.com site. Why do we do this?, because many of the RTK2go users here end up operating a SNIP network of their own. You can also download and evaluate your own copy of SNIP® from here. It is one part of the overall simple NTRIP™ project created by SubCarrier Systems Corp. (SCSC).
In diesem Artikel soll es darum gehen, wie ich YouTube so datensparsam wie möglich konsumiere und dies noch in der Konsole.
Barman (Backup and Recovery Manager) is an open-source administration tool for disaster recovery of PostgreSQL servers written in Python. It allows your organisation to perform remote backups of multiple servers in business critical environments to reduce risk and help DBAs during the recovery phase.
Barman is distributed under GNU GPL 3 and maintained by 2ndQuadrant, a platinum sponsor of the PostgreSQL project.
PeerTube is a software that you install on a web server. It allows you to create a video hosting website, so create your "homemade YouTube".
The difference to YouTube is that it's not intended to create a huge platform centralizing videos from the whole world on a single server farm (which is horribly expensive).
On the contrary, PeerTube's concept is to create a network of multiple small interconnected video hosting providers.
Tvheadend is a TV streaming server and recorder for Linux, FreeBSD and Android supporting DVB-S, DVB-S2, DVB-C, DVB-T, ATSC, ISDB-T, IPTV, SAT>IP and HDHomeRun as input sources.
Tvheadend offers the HTTP (VLC, MPlayer), HTSP (Kodi, Movian) and SAT>IP streaming.
Multiple EPG sources are supported (over-the-air DVB and ATSC including OpenTV DVB extensions, XMLTV, PyXML).
The Analog video (V4L) is supported directly up to version 3.4.
In recent version, the pipe:// source (in IPTV network) might be used to obtain the MPEG-TS stream generated by ffmpeg/libav from a V4L device.
So far, there are 1,082 pages in the MultimediaWiki. We would appreciate any knowledge you can contribute, for that is what the Wiki concept is all about. If you need help deciding what to write about, check the wanted pages for ideas.
Note that, due to spam and vandalism, you must have an account to edit this Wiki. Further -- again due to excessive automated spam and vandalism -- we have had to close general registration. If you would like to contribute, please contact Multimedia Mike for registration.
To stream video and audio from A20SOM-EVB, ffmpeg and crtmpserver are used. FFmpeg is used to encode the video and audio from A20SOM-EVB csi-camera and mic-in and then feed the stream to crtmpserver. Crtmpserver act as streaming server to provide rtmp stream for flash player, or rtsp stream for video player such as videolan.
If the csi camera is not yet functioning on the default debian distro, please follow my previous article how to enable csi-camera on A20SOM-EVB.
