Does TWC QoS down Earthlink traffic?

Any ideas on how I could tell if I’m the only one in my area (this side of the second hop) seeing this, and if not, whether this is TWC just QoS’ing Earthlink traffic behind their own?

I wouldn’t want to switch from Earthlink to TWC cable if it’s not going to make a difference, but if it would, I’d happily do so. Smile

after iOS 5 upgrade, media on iPhone all ‘gone’ and the space is now ‘Other’

Apparently this has been happening for ages (at least going back to iTunes 7.x) and it appears to be related to sync operations not happening correctly/normally/whatever (although I didn’t perceive any sync problems on this particular phone).

As unexpected of a workaround as it is, I got lucky and ran across someone else that hit this today with their own iOS 5 upgrade.  Just drag a new song not currently on the device from the library onto the device, and sure enough, that did the trick.  The particular song synced over when I dropped it, and that triggered whatever necessary sanity check code that then resynced everything else on the device.  Yay!

Why are my TFS collection backups so big?

Not much interesting here, but given the relatively small size of our source tree, the backups were larger (4GB each) than I expected.

The SSMS ‘disk usage by top tables’ showed it was attachments:

and while there’s no FK from tbl_AttachmentContent to tbl_Attachment, you don’t really need one for checking size, since the size is stored in tbl_Attachment.

So, using linqpad to check which types of attachments were taking up the space showed it was test run files:

 

Code Snippet
  1. from att in this.Tbl_Attachments
  2. group att by att.AttachmentType into ag
  3. let totalSize = ag.Sum(a => a.CompressedLength)
  4. orderby totalSize descending
  5. select new
  6. {
  7.    Type = ag.Key,
  8.    Size = totalSize,
  9. }

Modifying it slightly to group on filename instead and including count showed which particular files in my test runs were taking up the most space (not that it much matters, I was more just curious).  Keeping fewer builds/runs around isn’t going to be at the file scope. Smile

Code Snippet
  1. from att in this.Tbl_Attachments
  2. group att by att.FileName into ag
  3. let totalSize = ag.Sum(a => a.CompressedLength)
  4. orderby totalSize descending
  5. select new
  6. {
  7.    File = ag.Key,
  8.    Count = ag.Count(),
  9.    Size = totalSize,
  10. }
