  • CryptographicException: The handle is invalid.

    - by Wil Peck
    More than once I have come across the issue where we have had a problem using an X509Cert from the certificate store.  Everything is configured properly in the certificate store but when we attempt to create the signature we end up with a cryptographic exception for no apparent reason. See CryptographicException: The handle is invalid post by Benoit Martin explains the problem and shows how this issue can be resolved. Technorati Tags: Exceptions,Help,Cryptography

    OTN Architect Day - Boston - Sept 12: What to Expect If you've never attended an OTN Architect Day, here's a little preview. You start with a continental breakfast. Then you have keynotes by an Oracle expert, and a member of the Oracle ACE community. After that come the break-out sessions, so you have your choice of two sessions in each time slot. So you'll get in two breakouts before lunch. Then you eat. After that there's a panel Q&A during which the audience tosses questions at the assembled session speakers. Then it's on to another set of break-out sessions, followed by a short break. Then the audience breaks into small groups for round table discussions. After that there's a drawing for some cool prizes, followed by the cocktail reception. All that costs you absolutely zero. Register now.

  • What's the problem with Scala's XML literals?

    - by Oak
    In this post, Martin (the language's head honcho) writes: [XML literals] Seemed a great idea at the time, now it sticks out like a sore thumb. I believe with the new string interpolation scheme we will be able to put all of XML processing in the libraries, which should be a big win. Being interested in language design myself, I'm wondering: Why does he write that it was a mistake to incorporate XML literals into the language? What is the controversy regarding this feature?

  • Manipulating XML Data in SQL Server

    When the average database developer is obliged to manipulate XML, either shredding it into relational format, or creating it from SQL, it is often done 'at arms length'.

  • Oracle SPARC SuperCluster and US DoD Security guidelines

    - by user12611852
    I've worked in the past to help our government customers understand how best to secure Solaris.  For my customer base that means complying with Security Technical Implementation Guides (STIGs) from the Defense Information Systems Agency (DISA).  I recently worked with a team to apply both the Solaris and Oracle 11gR2 database STIGs to a SPARC SuperCluster.  The results have been published in an Oracle White paper. The SPARC SuperCluster is a highly available, high performance platform that incorporates: SPARC T4-4 servers Exadata Storage Servers and software ZFS Storage appliance InfiniBand interconnect Flash Cache  Oracle Solaris 11 Oracle VM for SPARC Oracle Database 11gR2 It is targeted towards large, mission critical database, middleware and general purpose workloads.  Using the Oracle Solution Center we configured a SSC applied DoD security guidance and confirmed functionality and performance of the system.  The white paper reviews our findings and includes a number of security recommendations.  In addition, customers can contact me for the itemized spreadsheets with our detailed STIG reports. Some notes: There is no DISA STIG  documentation for Solaris 11.  Oracle is working to help DISA create one using their new process. As a result, our report follows the Solaris 10 STIG document and applies it to Solaris 11 where applicable. In my conversations over the years with DISA Field Security Office they have repeatedly told me, "The absence of a DISA written STIG should not prevent a product from being used.  Customer may apply vendor or industry security recommendations to receive accreditation." Thanks to the core team: Kevin Rohan, Gary Jensen and Rich Qualls as well as the staff of the Oracle Solution Center and Glenn Brunette for their help in creating the document.

  • Ray Tracing concers: Efficient Data Structure and Photon Mapping

    - by Grieverheart
    I'm trying to build a simple ray tracer for specific target scenes. An example of such scene can be seen below. I'm concerned as to what accelerating data structure would be most efficient in this case since all objects are touching but on the other hand, the scene is uniform. The objects in my ray tracer are stored as a collection of triangles, thus I also have access to individual triangles. Also, when trying to find the bounding box of the scene, how should infinite planes be handled? Should one instead use the viewing frustum to calculate the bounding box? A few other questions I have are about photon mapping. I've read the original paper by Jensen and many more material. In the compact data structure for the photon they introduce, they store photon power as 4 chars, which from my understanding is 3 chars for color and 1 for flux. But I don't understand how 1 char is enough to store a flux of the order of 1/n, where n is the number of photons (I'm also a bit confused about flux vs power). The other question about photon mapping is, if it would be more efficient in my case to store photons per object (or even per Object's triangle) instead of using a balanced kd-tree. Also, same question about bounding box of the scene but for photon mapping. How should one find a bounding box from the pov of the light when infinite planes are involved?
