To find a performance regression between Node v0.10 and v0.11, I used Joyent Manta instead of git-bisect to find the offending commit(s) among all 550 commits of our development branch in under 4 minutes.
More sophisticated series of shell scripts that pull the originals, resize, reformat, extract XMP metadata, and use MapReduce to make a file of metadata one-line descriptions.
Our friends from BayLISA came up to San Francisco again the other night. The occasion was the launch of Brendan Gregg's new book, Systems Performance: Enterprise and the Cloud, and we had the first copies hot off the press to raffle off to three lucky attendees.
Node.js has some built-in DTrace probes for looking at HTTP request start/done and GC start/done, and I wrote [nhttpsnoop] to report latency based on these probes.
Last week I debugged a Node issue where under some conditions, fork() failure could result in some file descriptors being closed, leading shortly to bedlam. In the best cases, the program would immediately crash, but often it would just do the wrong thing. This happens a lot, of course, and in many ways it's worse than a crash because you have no core dump nor even a stack trace to go on.
Simple JPEG resizing on Manta and the speedup compared to my notebook, mjob share, tips on preserving image color, and uploading large data sets.
This post is the one of several about how we operate Node.js in production at Joyent.
This is part of a series of blog posts on cloud security. Carlos Cardenas is a security expert who came to Joyent from The Institute for Cyber Security ICS at the University of Texas, San Antonio. While at ICS, Carlos worked under Ravi Sandhu, PhD, one of the leading security experts in the world.
At Cloud Beat's fireside chat, Konstantin Gredeskoul, CTO of Wanelo and Bryan Cantrill, Joyent's SVP of Engineering discuss Wanelo's use of Joyent Manta.
In Part 1 of this webinar series Joyent's lead Manta architect, Mark Cavage, provides an introduction to, and explores the motivations for building Manta. Mark also provides insight into its underlying architectural features and reveals top use cases.
Key management is the system or act of managing cryptographic keys in a system which includes: generation, destruction, replacement, use, and distribution.
Last week, several Joyent engineers attended Surge in Washington, D.C. The highlight for several of us was the keynote by Gene Kranz (of Apollo 13 fame) about his days at Mission Control.
