Here is my clang version: Ubuntu clang version 3.2-1~exp9ubuntu1 (tags/RELEASE_32/final) (based on LLVM 3.2) And what I don't know is the meaning of "exp9ubuntu1"? Please Help, Thanks.
Each package name is in the form: package-XubuntuY*_amd64(i386)  So my questions are:   What does the X stand for? What does the Y stand for?   for example binutils_2.22-6ubuntu1.3_amd64  What is the meaning of the numbers 6 and 1.3
How can I resize NTFS partition in GParted? How do I create a master workbook in excel? In powerpoint we have something called a master slide.  I want the same idea for excel.  I want to create a template that I can work on with formulas and I want it to update all children files.  Example: I have a budget template.  This template has a budget listing all required equipments and their cost for a project.  We then have a formula that calculates the total cost of all equipment. I want to update only the template file with equipment and formulas, but I want the actual files (children) to contain the costs (because they might be different costs for different locations, but the rest of the budget and its formulas are shared).  Its pretty much exactly what a master slide in powerpoint is, if you've ever used that you should understand what I'm trying to do pretty easily.  One master file to store formulas, and a bunch of children files that store the data to be accessed by those formulas.  This way if a formula needs to be changed, the templates is adjusted and all other files update accordingly.  Any ideas?  I'd prefer not to have to use VB, and I'd also like a solution that works for both mac and windows.  Found  question but no answers.  I've already created a template, but that doesn't seem to update the other files when I modify it. PHP: How do I loop through every XML file in a directory? Solve $x^2$ $mod$ $23 = 7^2$ What is the procedure to solving $x^2$ $mod$ $23 = 7^2$? According to WolframAlpha, there is no integer solution but I am completely confused as to what steps was taken to determine that.  Before asking the question, I did try to solve this using brute force by plugging in some arbitrary numbers to see whether the square of that number mod $23$ gave me a remainder of $49$ but the procedure was quite tedious. Hence the reason I turned to WolframAlpha.   Going back to the question, I want to know how WoflramAlpha determined that there was no integer solution to solving for $x$. I recentely tried to log-in / sign-up for  using my SE account (which works on ,  and sign-up here) but it showed me an OpenID related error.

When I feed my cat or my dog, the package tends to say "Dog Food" or "Cat Food."  In contrast, I give my chickens "chicken feed" or "poultry feed."  Likewise, a cow's silage is her "feed."  Why does this distinction exist?  Is there an historical or grammatical explanation, or is it merely idiom? Filling NoData gaps in raster using ArcGIS Desktop? Is it appropriate to buy a "thank you" gift for a PhD supervisor? I am nearing the end of my PhD and I would quite like to buy a "thank you" gift for my supervisor (although, she's the socially awkward type who I'm sure will be greatly embarrassed to receive one).  I'm just wondering whether a gift is the done thing? And if so, what sort of gift seems appropriate? I suppose a bottle of wine would be a safe choice? How did Thanos know about the power of "The Snap"? In the scene on Titan with Doctor Strange in Avengers: Infinity War, Thanos said,     With all six Infinity Stones, I will simply snap my fingers and it would all cease to exist.   Then again, in the very first scene with Thor and Loki, when Maw gave Thanos the Space Stone, he said that no one has ever worn two Infinity Stones together.   So how come Thanos knew about the power of the Snap? Because as Wong puts it to Tony, the Big Bang hurled the six Infinity Stones across the universe.   So if no one had collected all the six stones before Thanos, then how did he know about the ability to "Snap"? Do spellcasters know when a dismissable spell has been broken? Do spell casters know how long their spells are active, and can they tell at a glance?  Specifically lets talk about , as I know its a permanent duration and dismissable. Does the spell caster who put someone under this spell know how long it is active? Could they tell automatically just by seeing the person (without any clues like them walking in a maze without difficulty or reacting to a sound)? So could they tell if someone has broken the spell they cast? Does there exist a magical shell piping which would allow easily to grep through bunch of .gz log files without needing to extract them somewhere?  .gz files are Apache logs, result of log rotation. I'd like to quickly check how often certain URIs are accessed in the past. How to get apt-cacher-ng to download AND cache packages from Apt HTTPS repositories? Are {/bin, /lib, /sbin} symlinks into /usr in Ubuntu? I do not have access to an Ubuntu system or chroot. I was hoping if someone could tell me if the  is accurate in saying:     For Quantal, merged /usr should be supported. On new systems installer should create {/bin, /lib, /sbin} symlinks into /usr. Interpret geometrically the equation The function $f$ is convex when:  $$f(tx+ (1-t)x', ty + (1-t)y') ≤  tf(x,y) + (1-t)f(x', y')$$  for all numbers $0≤t≤1$ and all pairs of points $(x,y)$ and $(x',y')$ in the domain of $f$ (the whole of $R^2$)  How would I interpret this geometrically? Also what is an example of a convex function whose graph is not a plane? I'm trying to run down a memory leak in a windows forms application.  I'm looking now at a form which contains several embedded forms.  What worries me is that the child forms, in their constructor, take a reference to the parent form, and keep it in a private member field.  So it seems to me that come garbage-collection time:  Parent has a reference to the child form, via the controls collection (child form is embedded there).  Child form is not GC'd.  Child form has a reference to the parent form, via the private member field.  Parent form is not GC'd.   Is this an accurate understanding of how the garbage collector will evaluate the situation?  Any way to 'prove' it for testing purposes? Are "beginner questions" allowed on Stack Overflow? I noticed that  (about basic  syntax) received a lot of downvotes as soon as I posted it. Is there any specific policy against the posting of questions with "obvious" answers on Stack Overflow?  I'm unclear as to why questions with "obvious" answers aren't usually well-received by the community - are beginner questions considered harmful for some reason? ("Obvious" is a relative term, of course - this type of question would be helpful to anyone who was learning C# for the first time, but it wouldn't be helpful to an experienced C# developer.) Does math have an incorrect notation / syntax? I don't mean writing misaligned notation (google), but when you take something like a number to powers to powers to powers, $${{2^2}^2}^3$$ (I was told this is incorrect notation by a teacher). Is it really incorrect, or does it just need to be simplified with parentheses? Do people write maths like this?  a radical expression with the root being a radical expression? $$\sqrt[\sqrt{2^3}]{2}$$ Show finite complement topology is, in fact, a topology Why can't I use a type argument in a type parameter with multiple bounds? let ${v_1}, {v_2} $ be orthonormal basis for subspace $W$.
