Windows 2008 and Vista SP2

2009 May 30 – 7:22 am

windows-server-2008Windows 2008 and Vista SP2 is out and coming to a Windows Update near you soon.

There are no new features to get excited about just a huge list of security and bug fixes for the operating systems. We’ve been running the Beta and then the RC (Release Candidate) for quite some time on various PCs and servers. They’ve been stable and we have now installed the full service pack on most of our machines. No problems spotted so far so, get to it everyone.

A spreadsheet of all the included fixes can be found at this direct Microsoft link.


Diskeeper for Hyper-V

2009 May 30 – 7:13 am

diskeeperlogo So Diskeeper are still around and now launching a tool for Defraging Hyper-V machines (both guest and host).

I wonder how many people remember the days of defraging their Windows 9x boxes and watching the little bars move around, feeling great when everything looked tidy and then knowing the machine felt faster when using it ? So my next question is how many people still defrag and does it really make any serious difference ? The last few times I’ve tried it on various machines over the years I’ve noticed no visable difference at all. Just an hour or so wasted waiting for the machine to finish doing the defrag so I can get back to using it :) .

Of course the likes of diskeeper will through great stats at you about how much it makes things quicker. But in the real world does defraging have much of a place anymore ?

More importantly am I bothered enough or do I believe it may have a real difference enough to actualy bother installing it again and see if there’s a difference ….. ?

Microsoft Exchange Server 2010 Beta

2009 May 13 – 5:29 pm

If you’re that sort of person who’s into mail, you’ve probably heard and used Exchange at some point in your life. What you’ve probably not heard much about is the Exchange Server 2010 Beta.

You could be forgiven any thoughts of why; Exchange 2007 has only just recently emerged, and it’s not all that popular – especially given the uptake that we’ve seen with our current and prospective clients. You might even be considered for considering it as a service pack. However, when you delve into it you can see that it’s definately more than that.

There are some pretty cool features making their way into Exchange 2010, and we certainly hope that they all make the cut:

  1. OWA supports Firefox and Safari, out of the box.
  2. OWA now has a “conversation view”, much like the Threaded view available in other mail clients.
  3. MailTips – a brand new feature for OWA (and Outlook 2010) that warns you if you’re about to do something silly. Check out this entry from MS Exchange Team Blog (You had me at EHELO) for more.
  4. The ability to move a mailbox, online. We can finally moe a mailbox, and not take out the user’s access to it!
  5. Mail Moderation – you can redirect incoming mail to a manager, allowing any incoming mail to be vetted before sending it onto the recipient. All sorts of legal ramifications there, we think, but very cool nonetheless.
  6. Users can archive direct to a secondary mailbox, rather than littering the network with PST files, or needing the use of other Mailbox Archivers, such as Redgate’s ESA.
  7. Users can now manage their own distribution groups.
  8. Multimailbox search allows specified users to search across multple mailboxes (useful for HR or other purposes we’d imagine).

There’s a whole bunch of other stuff that’s in there, but unless you’re a hardcore system administrator we’re genuinely not sure that it’ll be that interesting. But if you are read on.

  • IO optimization, which means that Exchange runs much more nicely on SATA disks. I’m still not 100% sure that’s a fantastic feature – after all, you are using proper disks in your Exchange box? Right?
  • Replicated mailbox databases allow for the use of concatenated disks instead of insisting on RAID arrays
  • Database-level failover (quite frankly, this is awesome)
  • Page patching, which automatically repairs corrupted database pages from copies
  • Automatic repair of corrupted database pages from copies
  • Voice mail previews (if you have unified messaging facilities) allow you to access your voicemails, automatically transcribed into text
  • “Federations” (too much Trek for the engineer who came up with this name) allows you to more easily trust Exchange servers of partner organizations, facilititating sharing calendars, etc.

We’re quite sure that there’s a whole lot more in there – we’ve just not had the time or opportunity to find it yet!



A little over a week ago Parallels released an update for Parallels desktop, for OSX, that fixes a number of bugs we’ve been finding a little irritating – including the mouse cursor disappearing randomly. If you’re a gamer at all you’ll also find and love the improved 3D performance!

Full details can be found on the Parallel’s forum in this thread.
