card readers - CF
by Trevor Cordes 05 Apr '11

05 Apr '11

I'm looking for opinions on internal card readers, like the ones you install in 3.5" bays. Particularly I'm looking for ones with tight and deep CF slots. At my customer sites, staff often bend the CF slot's pins all the time and a tighter/deeper slot might help keep the CF card better guided into the pins. CF is sure a junky format for frequent insertions. Thanks!

libEAT-MY-DATA
by Adam Thompson 04 Apr '11

04 Apr '11

Just came across this: libeatmydata. http://www.flamingspork.com/projects/libeatmydata/ Disables fsync, open(O_SYNC) and friends. Can speed up certain applications by a factor of 100x or more under certain circumstances. Library so named (libEAT-MY-DATA) because of the obvious danger. Use at own risk. Interesting concept, possibly a valid option when you *know* you can recreate the data trivially (and crash-consistency therefore doesn't matter), or where maximum possible performance is substantially more important than complete loss of data. If you use it just to "make my database go faster", well, you deserve what you get. -- Adam Thompson <athompso(a)athompso.net>

Portable email gadget
by Montana Quiring 03 Apr '11

03 Apr '11

Hello, I'm looking for a handheld gadget that just does email VIA WiFi. It needs to have a little Black Berry-esk keyboard. The screen can be black and white. I'm looking to pay < $50. Running embedded Linux would be preferred. It would need to be battery powered. Anyone seen anything like that? Regards, -Montana Quiring CTO of QMTS http://qmts.ca

I have always wondered why grep was so fast. Interesting email by the original GNU grep author. http://lists.freebsd.org/pipermail/freebsd-current/2010-August/019310.html Enjoy, Bill

Fwd: TaPP '11 Submission Deadline Approaching

FYI... -------- Original Message -------- Subject: TaPP '11 Submission Deadline Approaching Date: Fri, 1 Apr 2011 14:36:29 -0700 From: Lionel Garth Jones <lgj(a)usenix.org> To: info(a)muug.mb.ca, gedetil(a)muug.mb.ca We're writing to remind you that the submission deadline for the 3rd Workshop on the Theory and Practice of Provenance (TaPP '11) is quickly approaching. Please submit all work by April 8, 2011, at 11:59 p.m. PDT. More information and submission guidelines are available at http://www.usenix.org/tapp11/cfpb TaPP '11 will bring together researchers and practitioners doing innovative work in the area of provenance. With the deluge of digital data we are currently experiencing, it has become increasingly important to capture and understand the origins and derivation of data--its provenance. Provenance provides important documentation that is an essential part of the quality of data, and it is essential to the trust we put in, for example, the data we find on the Web and the data that is derived from scientific experiments. The workshop may cover any topic related to theoretical or practical aspects of provenance, including but not limited to: provenance in databases, work flows, programming languages, security, software engineering, or systems; provenance on the Web; or real-world applications of or requirements for provenance. The Program Committee is determined to make TaPP '11 a real workshop at which new ideas are discussed and developed and where the participants can learn how other subjects make use of provenance. While the workshop will have online proceedings, the Committee does not want the workshop to become another "mini-conference" that has nothing but paper presentations. The Committee is eager to receive short papers and vision papers describing challenges for provenance research, brief descriptions of new applications, proposals for mini-tutorials, pie-in-the sky research ideas, and anything that will create a successful workshop. While brief and readable descriptions of research are encouraged, recycled conference submissions are strongly discouraged. TaPP '11 will take place June 20-22, 2011, in Heraklion, Crete, Greece, the week after the meeting of ACM SIGMOD in Athens. We look forward to receiving your submissions! Sincerely, Peter Buneman, University of Edinburgh Juliana Freire, University of Utah TaPP '11 Program Co-Chairs tapp11chairs(a)usenix.org ------------------------------------------------------------------ TaPP '11 Call for Contributions 3rd Workshop on the Theory and Practice of Provenance (TaPP '11) June 20-22, 2011, Heraklion, Crete, Greece http://www.usenix.org/tapp11/cfpb Submission deadline: April 8, 2011, 11:59 p.m. PDT ------------------------------------------------------------------
