I'm wondering if someone is publishing statistics on email usage on the internet.
The main number I'm looking for is average message size on a large scale sample data over time.
If someone doing spam/security checks is accumulating this data and publishing it I'd like to know.
Barracuda, Trend, Symantec, SpamCop, etc.
I'm testing out a Cisco SA520W for some remote retail locations we manage.
The one thing that is currently holding me back on it is I haven't found a way to set the VPN connection to connect when the device comes on, or better yet to "always have it up" to where if it loses the connection it tries to re-open it.
I can live with it just coming up on boot as the users on site are typically familiar with power cycling the firewall before calling in with issues.
The IPSec VPN comes up and functions fine, but has to be done so manually.
I have a web application that was using SubSonic version 2.1.0. While adding some new features I came across a bug in that version that was fixed in 2.2.0.
On my dev box, I switch the version of the DLL referenced and everything worked fine.
After updating the Windows 2008 R2 server running IIS 7.5, the bug has persisted.
I searched the server and replaced every instance of SubSonic.dll with the latest version.
Restarted the site, the app pool and then the entire server.
I ran SysInternal's Process Explorer and checked the w3wp.exe process for the site and according to it, w3wp.exe is referencing version 2.2.0 of SubSonic.dll.
I've copied the database and site files from that Windows 2008 server to another 2008 (one that never had v2.1.0 loaded) and confirmed the bug doesn't occur there.
Based on the symptoms, it seems that the server is holding on to the 2.1.0 version of the DLL but I cannot figure out where it has it and how to get rid of it.
Additional Info:
I checked the GAC, no SubSonic dlls.
Installed 2.2.0 into the GAC using gacutil from the Windows SDK 6.1
Setup a new Site and AppPool on the server and uploaded a fresh copy of the site files from my dev box.
Site is C# .Net 2.0 using MVC 1 with nHaml 2.0 for the view engine.
Used cygwin find to search the filesystem for any files with the same size as the 2.1 DLL.
Found a couple copies that the Windows search box didn't, they were just in a backup folder, shouldn't have been in use, deleted just in case.
The only remaining files with the same size as the 2.1.0 version are:
./Windows/System32/DriverStore/FileRepository/prnca00z.inf_amd64_neutral_27f402ce616c3ebc/Amd64/CNBDR4_5.DLL
./Windows/winsxs/amd64_microsoft-windows-getuname.resources_31bf3856ad364e35_6.1.7600.16385_en-us_eca42f29f7e4d0ea/getuname.dll.mui
./Windows/winsxs/amd64_prnca00z.inf_31bf3856ad364e35_6.1.7600.16385_none_ea189c313845a10e/Amd64/CNBDR4_5.DLL
./Windows/winsxs/x86_microsoft-windows-getuname.resources_31bf3856ad364e35_6.1.7600.16385_en-us_908593a63f875fb4/getuname.dll.mui
Which appear to have nothing to do with the SubSonic DLLs.
Update 8-30-2010
Reasoning regarding bug for suspecting the DLL version in use is the issue:
The error that is happening is rather specific and on my development box when I change between 2.1.0 and 2.2.0 of the DLL it predictably happens under 2.1.0 and not 2.2.0.
I've also put the site to a different server and it operates fine with 2.2.0, so it working is not unique to my development box.
Basically, in version 2.1.0 when doing a paged result query the WHERE clause elements are doubled up so the generated query would end up with "WHERE CreatedOn > '8-1-2010' AND CreatedOn > '8-1-2010'".
Although redundant, syntactically this is fine to execute.
When you add in a SubQuery is when it goes wrong because the SubQuery object has its SQL generated twice and the second time instead of starting with a WHERE it starts with an AND because a boolean flag on the object tracking if the WHERE has been started is true at the start from the first time generating the SQL.
So under 2.1.0 you will get "WHERE id IN (SELECT id FROM table WHERE CreatedOn > '8-1-2010') AND id IN (SELECT id FROM table AND CreatedOn > '8-1-2010')"
In 2.2.0, the WHERE clause on a paged query doesn't repeat its conditions and so the SubQuery doesn't generate improper SQL syntax.
The SQL generation occurs within the DLL and I can observer through SQL Profiler that 2.1.0 generates the bad syntax but when I run locally with 2.2.0 the syntax is proper.
Because this error is such a specific situation, the site works fine in general, it is on just a specific search query that this happens and it is very easily to repeat that with no code, data or data structure or other environment changes, it errors under 2.1.0 but not 2.2.0.
I hadn't given specifics on the bug previously as it doesn't seem relevant to solving the issue, the resolution should be regarding any 3rd party dll loaded from the bin directory of an asp.net site being cached and not updating version after app pool, service and machine reboots, new site container creation, deletion and reupload of all site files, etc.
I have a rails app on an old Ubuntu server I need to move onto a new machine.
I haven't worked with ruby on rails so I don't really know anything about the structure of the app.
I want to load this onto an Ubuntu 8.04 AMI on Amazon EC2 and am looking for any information regarding the migration process such as:
Do I copy over the entire folder defined as the application root in the mongrel config (for ex: /u/apps/myapp/current) or just certain folders?
Am I looking for trouble if I go with the latest versions of ruby and the various gems?
Any general gotchas to look out for in the process.

I am trying to migrate a Classic ASP app onto a Windows 2008 R2 server.
The application features run fine, but I am having issue with session.
The application keeps the logged in user information in session and I am constantly getting knocked out as if the session had expired.
While debugging I have discovered the sessions are not expiring but instead I am getting 2-3 different Session IDs in use by one browser.
I am outputting Response.Write(Session.SessionID) on various pages in the application and I can sit there and hit refresh over and over and watch the number changed between these 2-3 SessionIDs randomly.
The sessions are still valid because when I refresh and get the Session ID that I logged in under the page is displayed (because the security check was successful) and when I get one of the other Session IDs I get the "you aren't logged in, you need to log in" message.
If I close and re-open the browser, same story just the set of IDs are new.
This happens with IE8, Firefox and Chrome from multiple computers.
Things I've tried:
- AppPool set to No Managed Code and Classic
- Output Caching set .asp to never cache
- ASP Session Properties enabled and disabled asp session state and confirmed it affected page (error trying to read Session.SessionID when disabled)
Things I've tried just in case but shouldn't have anything to do with ASP Session:
- Disabled compression
- Changed ASP.Net Session State properties (InProc, StateServer, SQLServer, Cookies, URI, etc)

I have recently migrated an application from one server to another and am having some issues I am wondering if they are associated to HyperThreading.
In regards to my question, I currently don't have access to the old box. When I did, I know that in /proc/cpuinfo it showed 2 processors and the system had only 1 physical processor, so that tells me HyperThreading was enabled.
What I am wondering is if perhaps /proc/cpuinfo could be showing the two processors purely from an informational standpoint but the kernel wasn't compiled with SMP so the processes weren't hitting the HyperThreading Virtual CPU or if the lack of SMP in the kernal would mean the system would never even know to show the 2nd CPU in /proc/cpuinfo.
If anybody happens to have a box they know has multiple CPUs (HT preferred, but physical would be more info then I have right now) that has a non-SMP kernel loaded and could check their /proc/cpuinfo it would be much appreciated.
I have a user that is printing on top of pre-printed forms on a Lexmark T642 and so the page alignment needs to be very exact so that the data they print lines up with the boxes.
Currently the form is printing about 3/4 of a character off to the right.
I have looked through the settings on the printer drivers for default margin/offset settings.
I also looked at trying to define a custom page size but in the definitions for the page size it only takes Width and Height, no control for the printable area.
