A how and why primer on video transcoding: Webm to H.264 and more

Rendering videos seamlessly across browser types is often an arduous process for developers. It is important to consider the format and codec of a video file. Different browser types support different video codecs, which means that you need to provide multiple formats to ensure that your video renders on all browsers.

Browser
Video Codec
Audio Codec
Chrome
H.264, VP8, VP9
AAC, MP3, Vorbis, Opus
Firefox
H.264, VP8, VP9
AAC, MP3, Vorbis, Opus
Internet Explorer
H.264
MP3
Safari
H.264
MP3, AAC
iPhone
H.264
MP3, AAC
Android
H.264, VP8
MP3, AAC, Vorbis
Opera
H.264, VP8
Vorbis, Opus
Chrome Android
H.264, VP8, VP9
MP3, AAC, Vorbis
If you are looking for one codec to rule all web browsers, then your best bet is with H.264, which is supported on 98% of web browsers and is used for both HD and SD video encoding. There are other ways to optimize for speed and quality, but I won’t delve into them here.  The main problem people face is when they need to display user generated video content that is recorded in one format

Jepsen: MongoDB 3.4.0-rc3

In the past year and a half, MongoDB has put a good deal of work into improved read safety, enabled by the adoption of their new replication protocol and the WiredTiger storage engine. Dirty reads were addressed in 3.2 by introducing a majority read concern, and stale reads were addressed with the introduction of the linearizable read concern in 3.4. MongoDB contracted with Jepsen to analyze the safety of these mechanisms, and adopted Jepsen linearizability tests as a part of their continuous integration suite.
In November 2016, MongoDB requested Jepsen perform a followup analysis of a 3.4.0 release candidate (3.4.0-rc3) to confirm whether their linearizable read concern behaved as designed. We found critical design flaws in MongoDB’s old replication protocol (v0), and multiple bugs in the new replication protocol (v1). These errors allowed (and, for any cluster running the v0 protocol, still allow) MongoDB to lose acknowledged updates even at the
