What are the tiers in arena for awards in Hearthstone?  When do you get 3 boxes, 4 boxes etc?  Thanks
What is the list of keys and their corresponding wins?  I have it listing that the highest number of wins I've had in arena is a Champion key, but it doesn't say how many wins it was.
Solving $f(x+y) = f(x)f(y)f(xy)$ What is a good Hash function? I saw a lot of hash function and applications in my data structures courses in college, but I mostly got that it's pretty hard to make a good hash function. As a rule of thumb to avoid collisions my professor said that:  function Hash(key)   return key mod PrimeNumber end   (mod is the % operator in C and similar languages)  with the prime number to be the size of the hash table. I get that is a somewhat good function to avoid collisions and a fast one, but how can I make a better one? Is there better hash functions for string keys against numeric keys? The use of "real" in the following cases Possible Duplicate:             If you listen real close...      Can you swing by real quick...   Sentences like the above two are what I often hear in daily life. If I didn't hear them in the real world, I would probably be more ready to say "If you listen really close..." and "Can you swing by really quick...".  Is real being used as an adjective in this scenario? If so, is the usage of adj.+ adj. a common practice in English language? If $\forall x \in R, x^2-x \in Z(G)$, than $R$ is commutative Let $R$ be a ring such that for every $x\in R$ we have $x^2-x \in Z(G)$. Show that $R$ is a commutative ring.    My thoughts  What should I do? I could show that every $y \in R$ could be written in the shape $x^2-x$ but I don't know if that is true. We know that  $y \cdot(x^2-x) \ = \ (x^2-x)\cdot y$ for any $x,y \in R$, but that doesn't mean that $xy = yx$. Please give me a hint Can crumbled feta cheese last almost a year? talks about feta cheese in a brine or milk bath lasting up to three months.  What about crumbled feta?  I was looking through the fridge, and found a 1/2 pound open container of crumbled feta.  I have only used about an ounce of it.  There is no sign of mold on it, and it smells like feta cheese.  A small sample tasted okay.  The amazing thing is that I bought it in October or November: 8-10 months ago!  I have a recipe that calls for almost a 1/2 pound of feta, and I will be the only one eating it (so I'm not trying to impress anybody!).  I dislike wasting food, but I dislike being sick even more!  Is it safe to use dry crumbled feta that is so old? How to move /usr to a new partition? Stacks for Unity Launcher I'm looking forward to emulate the behavior of OS X Dock Stacks so that I can have, for instance, one stack for browsers and another one for IDES. People at ask ubuntu are doing a lot of cleaver stuff with custom Launchers and Quicklists (see ). So has anyone figured out how to have stacks in Unity? Anything fancier than a static Quicklist over a dummy folder icon? Compute the period of a decimal number a priori I noticed that , given an operation like $\frac{n}{m},\;n,m \in N$ that result in a periodic decimal number, computes really fast the length of the period.  E.g. $\frac{3923}{6173}$ has a period of 3086: .  I was wondering how this computation is done: is there some method to do this (except the trivial one of executing the division and looking for a sequence repetition) ? Proving that $n$-cycle has order $n$ Where can I find historical data on arrival and departure times of a particular flight? Where can I find historical data on flights, specifically Delta international flights?  I need to find out about cancellations, diversions and any other flight data pertaining on particular route at a given time.  This source has to be official and stand up to legal scrutiny. Strange Recurrence: What is it asymptotic to? So I have the following recurrence relation for the growth rate of an algorithm:  $T(n)$ = time taken by algorithm to solve problem of size n:  $$T(n) = T(n-1) + T(\lceil(n/2)\rceil)$$  Clearly this does not obey any polynomial law but now my question is what does it obey?  I merely want an asymptotic equivalence.  My guess is subexponential since this is faster than polynomial but clearly slower than any exponential form.  What though is the question.... What is the simplest SQL Query to find the second largest value? What is the simplest SQL query to find the second largest integer value in a specific column?   There are maybe duplicate values in the column. I have two examples of different scenarios that are confusing to me.  First, if I have a 1/1 creature with first strike and deathtouch, and my opponent blocks it with a 2/2 creature, will my creature die? I can see two alternative ways this could play out and I'm not sure which is correct.   My creature deals his first strike damage, immediately killing the opponent's creature before he is able to deal combat damage as a state-based effect. My creature deals his first strike damage, which would normally be lethal due to deathtouch, but state-based effects are not checked, and thus the opposing creature deals his damage and both die.   I'm almost positive in this case that it's the first option above.  What gets trickier is, for example, if a creature has first strike and a triggered ability "Whenever this creature deals combat damage to a creature, return that creature to its owner's hand."  This is not a state-based effect, but rather uses the stack. Similar to above, there are two possibilities.   My creature deals his first strike damage, and his triggered ability is placed on the stack. The stack waits to resolve until after all combat damage is dealt, so the opposing creature still kills mine. My creature deals his first strike damage, and his triggered ability is placed on the stack. Both players now gain priority between first strike and combat damage (which I don't think normally happens, thus my confusion). The stack finishes resolving, and the opponent's creature doesn't have a chance to deal damage.   Can someone clarify this area of the rules? Natural (human alpha-numeric) sort in Microsoft SQL 2005 We have a large database on which we have DB side pagination. This is quick, returning a page of 50 rows from millions of records in a small fraction of a second.  Users can define their own sort, basically choosing what column to sort by.  Columns are dynamic - some have numeric values, some dates and some text.  While most sort as expected text sorts in a dumb way. Well, I say dumb, it makes sense to computers, but frustrates users.  For instance, sorting by a string record id gives something like:  rec1 rec10 rec14 rec2 rec20 rec3 rec4   ...and so on.  I want this to take account of the number, so:  rec1 rec2 rec3 rec4 rec10 rec14 rec20   I can't control the input (otherwise I'd just format in leading 000s) and I can't rely on a single format - some are things like "{alpha code}-{dept code}-{rec id}".  I know a few ways to do this in C#, but can't pull down all the records to sort them, as that would be to slow.  Does anyone know a way to quickly apply a natural sort in Sql server?    We're using:  ROW_NUMBER() over (order by {field name} asc)   And then we're paging by that.  We can add triggers, although we wouldn't. All their input is parametrised and the like, but I can't change the format - if they put in "rec2" and "rec10" they expect them to be returned just like that, and in natural order.    We have valid user input that follows different formats for different clients.  One might go rec1, rec2, rec3, ... rec100, rec101  While another might go: grp1rec1, grp1rec2, ... grp20rec300, grp20rec301  When I say we can't control the input I mean that we can't force users to change these standards - they have a value like grp1rec1 and I can't reformat it as grp01rec001, as that would be changing something used for lookups and linking to external systems.  These formats vary a lot, but are often mixtures of letters and numbers.  Sorting these in C# is easy - just break it up into { "grp", 20, "rec", 301 } and then compare sequence values in turn.  However there may be millions of records and the data is paged, I need the sort to be done on the SQL server.  SQL server sorts by value, not comparison - in C# I can split the values out to compare, but in SQL I need some logic that (very quickly) gets a single value that consistently sorts.  @moebius - your answer might work, but it does feel like an ugly compromise to add a sort-key for all these text values. How are character special files and block special files different from regular files in a Unix-like system? Why are they called “character special” and “block special” respectively? $\mathbb{Q}[x,y]/\langle x^2+y^2-1 \rangle$ is an integral domain, and its field of fractions is isomorphic to $\mathbb Q(t)$ How can I let a footnote continue on the next page? I have a rather long footnote which breaks a listing in two parts, unnecessarily.  Since the listing is more important then the footnote I'd rather lake to have the footnote split.   Can I customize (one or all) footnotes to have a maximal length before they are continued on the next page? Or can I manually split a footnote in two to get the effect? Change files with Editor that need sudo permissions I want to change files with KomodoEdit that need sudo permissions. I can't start KomodoEdit with sudo, though (for whatever reason). Can I somehow grant Komodo permission to edit those files (in particular I am talking about apache2 files and /etc/hosts)? Status-* tags - moderator only? How can I fix "unbalanced brackets" in my data tag? Often, when making a command block contraption, you need to set an entity's data tag. These tags can sometimes be very long, with many layers of nested curly and square brackets. For example, this is the command to summon a villager with a single custom trade:  /summon Villager ~ ~ ~ {Profession:3,Career:2,Offers:{Recipes:[{buy:{id:minecraft:diamond,Count:6b}},sell:{id:minecraft:diamond_hoe,tag:{ench:[{id:16s,lvl:10s}]}]}}   The single-line command block interface of Minecraft makes it incredibly difficult to find and fix errors, especially when it comes to mismatched brackets. In fact, for illustration purposes, I put an error in the above command.  What techniques can I use to find and fix unbalanced square or curly brackets when writing long and complicated data tags?
