What is the difference between "the door opened" and "the door was opened"?  Are there subtle differences?
How can I reliably and accurately identify the passive voice in writing or speech? I'm not interested in advice about whether or not to use it yet... I just want to know for sure what it is, so that I don't look as stupid as .
Play Framework (2.1.3) doesn't run any tests When should I use # and = in ASP.NET controls? I have been using ASP.NET for years, but I can never remember when using the # and = are appropriate.  For example:  &lt;%= Grid.ClientID %&gt;   or  &lt;%# Eval("FullName")%&gt;   Can someone explain when each should be used so I can keep it straight in my mind? Is # only used in controls that support databinding? How do I get from Terminal 1 to Terminal 5 in Fiumicino Airport? What's the difference between the five masses: inertial mass, gravitational mass, rest mass, invariant mass and relativistic mass? How to get back a declined Outlook invitation I accidentally clicked "decline" on an Outlook invitation and now I can't reverse it -- the event has completely disappeared from my calendar!  How can I get back the event invitation and change my "Decline" to "Accept" or "tentative"? How to execute sp_send_dbmail while limiting permissions Is there a way to provide access to users in my database to execute  msdb.dbo.sp_send_dbmail without needing to add them to the MSDB database and the DatabaseMailUserRole?  I've tried this:  ALTER PROCEDURE [dbo].[_TestSendMail] (   @To NVARCHAR(1000),   @Subject NVARCHAR(100),   @Body NVARCHAR(MAX) ) WITH EXECUTE AS OWNER AS      BEGIN         EXEC msdb.dbo.sp_send_dbmail @profile_name = N'myProfile',             @recipients = @To, @subject = @Subject, @body = @Body     END   But I get this error:  The EXECUTE permission was denied on the object 'sp_send_dbmail', database 'msdb', schema 'dbo'.   Thanks! How to have colors in Milky-way? Many photos of Milky-way show it in nice colors instead of just the black of sky and white of the stars. Is the key to having those colors in the capturing of the image or in the post processing, or both? Or am I just doing it in a wrong time of year when the visible part of Milky-way is simply not showing color?  Here is a sample photo of how Milky-way looks like in Finland in September:    APS-C sensor camera, 18 mm, 30 sec, f/3.5, ISO 3200 - captured in pitch-black darkness of Finnish countryside, far far away from any citylights, at time when moon was still below visible horizon.  What I'd like to achieve is something like the photo in Vivek's answer to   I've just bought a wireless shutter release for longer bulb exposures, and have plans to build a barn-door tracking mount. But is longer exposure the needed trick, or what is? cron Vs. sleep - which is the better one in terms of efficient cpu/memory utilization? I use Chrome as my default browser. This includes my browser for work.  We have a trac setup that uses folder paths (see example) for the different projects  Example:   main.employertracsite.com/projects/projectname   I want the ability to manually sort the results that are displayed in the auto-complete.  Chrome displays auto-complete based on the usage history of a web address. Which means that a project that isn't my main focus is displayed in the url instead of the one that I've been using more lately.  Example:   main.employertracsite.com/projects/alliance is the project that I'm not using all the time anymore and is showing up in auto-complete main.employertracsite.com/projects/horde is the project that I am using more often now and want to show up in the auto-complete   I don't want to delete the alliance from my history, but I do want the ability to be able to manually adjust which project shows up in auto-complete. This will be more usable for me in the future because I'm constantly on different projects full-time and they each have their own area.  I also do not want to delete my history. How do I update the GUI from another thread? Which is the simplest way to update a Label from another Thread?   I have a Form running on thread1, and from that I'm starting another thread (thread2).  While thread2 is processing some files I would like to update a Label on the Form with the current status of thread2's work.   How could I do that? Helpful flags not getting updated after getting 'close question' privilege Possible Duplicate:          I recently got the ability to cast close votes. So, even if I flag a question as 'not constructive' or 'not a real question', it is still considered as a close vote. What is strange is that my 'helpful flag' count has stopped increasing after this change. Or at least it doesn't increase in cases where my flagging was automatically changed to a close vote and the post actually was closed. Is this how it is supposed to be?   I am guessing that once the post gets closed, the moderators are probably not bothered about marking flags as helpful. The only problem is that the Deputy badge will be much more difficult to get now. Earlier all the flags were getting converted to helpful, but now they just go in as close votes and don't show up on my profile page. This is a phrase I've heard many people use, and it sounds wrong to me; e.g.:     The thing about that is, is that she might take it the wrong way.   It seems to treat "The thing [...] is"—the entire phrase—as the subject of the sentence. Of course, even if that were allowed, the comma placement would still be questionable.  I'm curious to know:   Is there a name for this wording? Is it specific to a certain dialect? Is its etymology known? Orthographic scale of camera in Blender could somebody explain how orthographic scale is calculated in Blender? I am trying to match an orthographic view that I get from another software with that of Blender, but I am not able. Camera gets in the correct position but the zoom level is wrong.  Thanks, byte How can a regression be significant yet all predictors be non-significant? My multiple regression analysis model has a statistically significant F value however all beta values are statistically non-significant.   All the regression assumptions are met. No multicollinearity was found. Correlations among all predictors are all less than 0.60.   What else might be the cause of the insignificant predictors?
