Transpose some columns to rows using pivot with SQL 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? This is a question about American English usage of the word "already". As a UK resident I don't completely understand when I hear Americans give commands like "Stop it already!" In the UK the word already is not normally used in the imperative mood and the sentence I've just quoted would leave an English person thinking "If you're saying I've already stopped it why are you asking me to stop it again?" If one uses Shadow Evocation on a willing ally (e.g. Telekinetic Charge) can they choose not to disbelieve? Shadow Evocation  Nondamaging effects have normal effects except against those who disbelieve them. Against disbelievers, they have no effect.  Disbelief  Creatures encountering an illusion usually do not receive saving throws to recognize it as illusory until they study it carefully or interact with it in some fashion. A successful saving throw against an illusion reveals it to be false, but a figment or phantasm remains as a translucent outline. A failed saving throw indicates that a character fails to notice something is amiss. A character faced with proof that an illusion isn't real needs no saving throw. If any viewer successfully disbelieves an illusion and communicates this fact to others, each such viewer gains a saving throw with a +4 bonus.  (my emphasis) Voluntarily Giving up a Saving Throw  A creature can voluntarily forego a saving throw and willingly accept a spell's result. Even a character with a special resistance to magic can suppress this quality.  If I understand the above correctly,  If the ally believes the caster actually cast Telekinetic Charge, it seems they get a save which they could forgoe and so be guaranteed the benefit of the spell. &gt;&gt; We're good here. If the ally knows the caster didn't cast Telekinetic Charge, (say because of a high Spellcraft check or because she knows the caster's spell list) they have proof that the illusion isn't real and so need no saving throw. &gt;&gt; Even though she &quot;needs no saving throw&quot;, can she still choose to forego the save and be effected by the spell?  In other words, I think the question boils down to: Does one always have a choice not disbelieve an illusion, even when one has proof that it's not real? Java: How to find if a method is overridden from base class? Two git repositories in one directory? Is it possible to have 2 git repositories in one directory?  I'd think not, but thought I'd ask.  Basically, I'd like to check in my home directory config files (e.g. .emacs) which should be common across all of the machines I work on, but have a second repository for local files (e.g. .emacs.local), which contains machine-specific configurations.  The only way I can think of to do that is to have the local config in a subdirectory and ignore that subdirectory from the main git repository.  Any other ideas? I'd like to create a Gmail filter to filter all of my Google Calendar notifications into a separate folder.  Google Calendar notifications have headers that look like the following:  Reply-To: Helen Seu &lt;h...@g...com&gt; Sender: Google Calendar &lt;calendar-notification@google.com&gt; Auto-Submitted: auto-generated Date: Thu, 01 May 2014 05:25:28 +0000 Subject: Updated Invitation: Mobile design review @  Fri May 9, 2014 3pm - 4pm From: Helen Seu &lt;h..@g...com&gt; To: "Mike Burton" &lt;m...@g...com&gt;,    In particular, the email Reply-To is the user who created the meeting, and the Sender is calendar-notification@google.com.  For some reason, Gmail does not seem to allow you to filter on the Sender field of an email. Is there another clever way to filter Google Calendar notifications to a separate folder? I am confused by the behaviour of Currency fields in Multi-Currency environments. My app does a calculation on day X and stores its result in a record.  The custom page which displays a SUM of those values should always display the same as a database query. But...it does not. If I change Exchanges Rates those values change.  Was it wrong to store currency values in a Currency field, am I querying incorrectly or do I need to display a values that is manually calculated?  How does Multi-Currency and Currency fields work together? When are currency values converted and which conversion rate is taken into account?  I am confused?! Prove that if for every $x \in \mathbb{R}^N$ $Ax=Bx$ then $A=B$ Has confinement been experimentally observed? So, confinement has obviously been shown by lattice gauge theory to be a predicted aspect of QCD. However, to what extent has it been observed in experimental physics? What is scientific mind? How can you define scientific mind? What i think , it is a bend of mind that can be developed by any person(also one not related to field of science).This mind is fulfilled with abilities to observe clearly and sceptical about what he sees.It means the person will be keen to dig out truth and did not reaches to a conclusion easily. He utilizes facts enhance them with logical reasoning and fills the gap with their imagination.  Is there any disadvantage or any kind of limitation with scientific mind? Does anyone know where I can find cheat codes for Goldeneye 007 Wii? I know that the game hasn't even been out for a week, but does anyone know if any cheat codes have been released by Activision yet?  I know that they must exist since there is a cheat codes menu within the game. Origin and correctness of “ain’t no”? In contemporary American English usage, I come across sentences like:   I ain’t got no money.  Ain’t no man like him.    Saying ain’t no sounds incorrect to me because it is a double negative.  What is the origin of this particular construction? I wasn’t able to find anything online related to the origins of this incorrect usage. Basically the problem is that each time the assembly version changes (i.e. the user installs a new version of the application) all their settings are reset the the defaults (or more accurately a new user.config file is created in a folder with a different version number as the name)  How can I keep the same settings when upgrading versions, since using ini files or the registry seem to be discouraged?  When we used Clickonce it seemed to be able to handle this, so it seems like it should be able to be done, but I'm not sure how. Changing deleted partition back to NTFS without having to recover to another drive Recently, I accidentally deleted a partition off of my external hard disk. I had a copy of Minitool Power Data Recovery left over when the same drive had become RAW about a year ago. When I selected lost partition recovery, it immediately identified my deleted partition and allowed me to access and recover the files that were there.  My question is this. Is there any way to change the deleted partition back to NTFS without having to have a drive that you need to recover the files to and then move them back after formatting, as I don’t have any space left on either the computer or on my other external hard drive, so that I don’t need to buy a new one. The files on the disk were really important.  I am using Windows 7 Home Premium.  I appreciate any help in solving this crisis. Show that $\gcd(a^2, b^2) = \gcd(a,b)^2$ Sort a Map by values I've got two tables:  TableA ------ ID, Name  TableB ------ ID, SomeColumn, TableA_ID (FK for TableA)   The relationship is one row of TableA - many of TableB.  Now, I want to see a result like this:  ID     Name      SomeColumn  1.     ABC       X, Y, Z (these are three different rows) 2.     MNO       R, S   This won't work (multiple results in a subquery):  SELECT ID,        Name,         (SELECT SomeColumn FROM TableB WHERE F_ID=TableA.ID) FROM TableA   This is a trivial problem if I do the processing on the client side. But this will mean I will have to run X queries on every page, where X is the number of results of TableA.   Note that I can't simply do a GROUP BY or something similar, as it will return multiple results for rows of TableA.   I'm not sure if a UDF, utilizing COALESCE or something similar might work? SQL Server Agent Jobs and Availability Groups I'm looking for best practice in dealing with scheduled SQL Server Agent jobs in SQL Server 2012 availability groups. Maybe I missed something, however at the current state I feel that SQL Server Agent is not really integrated with this great SQL2012 feature.  How can I make a scheduled SQL agent job aware of a node switch?  For example I have a job running on the primary node which loads data each hour. Now if the primary goes down, how can I activate the job on the secondary which now becomes primary?   If I schedule the job always on the secondary it fails because then the secondary is read-only. Please help me to prove the following result:  I recall that the holomorph $Hol(\Gamma)$ of a group $\Gamma$ is the semidirect product $Hol(\Gamma)=\Gamma\ltimes_{\phi} Aut(\Gamma)$ where $\phi: Aut(\Gamma)\to  Aut(\Gamma)$ is the identity map.  Let $G=Hol(C_8)$. In addition let $f(x)\in \mathbb{Q}[x]$ be an irreducible polynomial of degree $8$, $L$ a splitting field of $f(x)$ over $\mathbb{Q}$ and suppose that $Gal(L/\mathbb{Q})\cong G$     Show that there is a subgroup of $S_8$ isomorphic to $G$   Thanks in advance.
