VirtualBox 4.1.18 Released…

VirtualBox 4.1.18 has been released. It’s a maintenance release and the downloads and changelogs are in the normal places.

It’s been about 2 years since I switched across to VirtualBox (when the shared virtual disks feature was introduced). In that time there have been loads of updates to the product. In the same time frame, VMware Server has had zero releases. I still get a lot of people writing to me about issues with VMware Server installations. I immediately tell them to ditch it. :)

PS. I’ve got nothing against VMware’s paid-for offerings, which do get updates. I just don’t see the point in using them when VirtualBox is free and works great for me.

Fedora 17 : My upgrade hell…

It’s been a few days since the final release of Fedora 17. I’ve been running it on VMs since the alpha release, but the day after the final release I decided to upgrade a real Fedora 16 machine. That’s where all the fun started…

I’ve now attempted Fedora 16 -> 17 upgrades on two physical servers and both have been destroyed by the process. In both cases, I had to do a fresh install, which worked cleanly and left a fully functioning installation. Perhaps I’m just very unlucky, but with a record of 0 for 2, my conclusion is that the upgrade process on Fedora 17 sucks so much ass it’s untrue.

As followers of the blog know, I try to keep my host machines pretty clean and do anything of significance in VirtualBox VMs. As a result, the recovery of both systems has been fine, if a little slow. In both cases, I did a clean install, then copied back all the VMs and that was pretty much it.

phpBB 3.0.10 Released…

I somehow managed to miss the release of phpBB 3.0.10 at the start of the year. The changelog is here.

All upgraded now. :)

WordPress 3.3 Released…

WordPress 3.3 is now live and ready for download.

The automatic upgrade was as smooth as ever. A couple of themes needed to be upgraded too. The menus are a little different and there is now a new persistent dashboard header, but it all seems like business as usual for the casual blogger like me.

Cheers

Previous releases have coincided with the Linux release. Let’s hope 2.3 for Linux will come soon!

Multi-Column Joins, Expressions and 11g

Introduction

I've already outlined in one of my previous posts that getting a reasonable cardinality estimate for multi-column joins can be tricky, in particular when dealing with correlated column values in the join columns.

Since Oracle 10g several "Multi-Column Join Cardinality" sanity checks have been introduced that prevent a multi-column join from producing too low join cardinalities - this is controlled via the "_optimizer_join_sel_sanity_check" internal parameter that defaults to true from 10g on.

VirtualBox 4.0.12 Released…

VirtualBox 4.0.12 has arrived. It’s another maintenance released with a bunch of bug fixes. You can see what’s changed here. Happy upgrading. :)
