The Linux OS long-term support release emerges, with a focus on cloud computing environments and ISV certifications. But it's still missing some critical enterprise software credibility.
Fundamentally, database performance tuning is done for two basic reasons, to reduce response time and to reduce resource usage, both of which can apply for any given situation. Julian Stuhler looks at database performance tuning, and why it remains one of the most important topics for any DBA, developer or systems administrator.
The Entity Framework provides a .NET class-based model of a data store, letting you query the model with LINQ, while the model do the background grunt work of contacting the data store to add, update, or delete data.
Scripting interactive operations can be a challenge, but the expect command is tailor-made for this. Juliet Kemp offers some tips on using this handy scripting tool.
<b>Groklaw:</b> "I confess I have been cracking myself up this time by reading old Rob Enderle, Paul Murphy, and Maureen O'Gara articles I had saved from the early days, each predicting solemnly Linux's doom. I can't tell you how much *more* fun it is to read them now than when they first showed up in 2003 and 2004"
<b>Techdirt:</b> ""Particularly ironic is the fact that the director of the movie enjoys the clips himself -- but of course, since the producer holds the copyright to the movie, the director has no real say in the matter."

Yes, a netbook can be an effective small business tool, especially when it has a larger-than-average display and pretty nifty video capabilities. Behold the HP Mini 311.
You're often required to repeat identical pieces of initialization code in every constructor of a class that declares multiple constructors. That's because unlike a few other programming languages, The C++ programming language doesn't allow a constructor to call another constructor of the same class. Luckily, this problem is about to disappear with the recent approval of a new C++0x feature called delegating constructors which are explained in this C++ tutorial.
I am using plone.app.blob to store large ZODB objects in a blobstorage directory. This reduces size pressure on Data.fs but I have not been able to find any advice on backing up this data.
I am already backing up Data.fs by pointing a network backup tool at a directory of repozo backups. Should I simply point that tool at the blobstorage directory to backup my blobs?
What if the database is being repacked or blobs are being added and deleted while the copy is taking place? Are there files in the blobstorage directory that must be copied over in a certain order?
