Mozilla Employee Denied Entry to the United States
Ugh. every non-USian tech worker's nightmare. curl developer Daniel Stenberg:
“I can’t think of a single valid reason why they would deny me travel, so what concerns me is that somehow someone did and then I’m worried that I’ll get trouble fixing that issue,” Stenberg said. “I’m a little worried since border crossings are fairly serious matters and getting trouble to visit the US in the future would be a serious blowback for me, both personally with friends and relatives there, and professionally with conferences and events there.”

an open source stream processing software system developed by Mozilla. Heka is a “Swiss Army Knife” type tool for data processing, useful for a wide variety of different tasks, such as:

Loading and parsing log files from a file system.
Accepting statsd type metrics data for aggregation and forwarding to upstream time series data stores such as graphite or InfluxDB.
Launching external processes to gather operational data from the local system.
Performing real time analysis, graphing, and anomaly detection on any data flowing through the Heka pipeline.
Shipping data from one location to another via the use of an external transport (such as AMQP) or directly (via TCP).
Delivering processed data to one or more persistent data stores.

Via feylya on twitter. Looks potentially nifty

A cool-looking new debugging tool for C/C++ from Mozilla.
Many, many people have noticed that if we had a way to reliably record program execution and replay it later, with the ability to debug the replay, we could largely tame the nondeterminism problem. This would also allow us to deliberately introduce nondeterminism so tests can explore more of the possible execution space, without impacting debuggability. Many record and replay systems have been built in pursuit of this vision. (I built one myself.) For various reasons these systems have not seen wide adoption. So, a few years ago we at Mozilla started a project to create a new record-and-replay tool that would overcome the obstacles blocking adoption. We call this tool rr.

Low runtime overhead; easy deployability; targeted at 32-bit (?!) Linux; OSS. (via Bryan O'Sullivan)

Coders performing code reviews of scientific projects: pilot study
'PLOS and Mozilla conducted a month-long pilot study in which professional developers
performed code reviews on software associated with papers published in PLOS
Computational Biology. While the developers felt the reviews were limited by (a) lack of
familiarity with the domain and (b) lack of two-way contact with authors, the scientists
appreciated the reviews, and both sides were enthusiastic about repeating the experiment. '

Actually sounds like it was more successful than this summary implies.

Kanban for MDN development
Mozilla's experience with Kanban. We've had good results in Amazon, too. good intro links in this post -- might start talking about it in Swrve...

open audio/video for the web, from Google; VP8 video codec, Ogg for audio, and a subset of Matroska as the container format. still a patents minefield, though, I'd guess

DNS Pre-fetch Exposure on Thunderbird and Webmail
Ugh, very bad idea indeed. A backchannel for spammers/phishers/attackers from the mail reader is something we definitely do not want to provide. This is why we chose to cut URLs at the registrar boundary for URIBL lookups in SpamAssassin
