I am in search for Functional Analysis Books.  I need a book which have lots of elementary problems.  I mean it should force us to think more which will give a deeper insight for functional analysis.  To be precise, I need lots of problems like Is $A$ open in the space $\ell^1$ with respect to norm $\|.\|_2$. Find a counterexample to this statement and etcetera.  I mean it shouldn't ask us trivial questions. It should ask us questions which will force us to think more and more from functional analysis
I am a EE grad. student who has had one undergraduate course in real analysis (which was pretty much the only pure math course that I have ever done). I would like to do a self study of some basic functional analysis so that I can be better prepared to take a graduate course in that material in my university. I plan to do that next fall so I do have some time to work through a book fully. Could some one recommend some good books to start working on this?   Thanks in advance
Trying to dual boot Ubuntu 14.10 with Windows 10, last one not detected SOQL result ordering in the absence of an Order By clause In the absence of an  in a SOQL query, what order will Salesforce return results in?  Clearly if ordering is important then Order By should be specified, but I recently encountered a question about what the order would be if it was undefined.  My initial thoughts were Salesforce would return them in whatever order suited them. Much like .  For simple queries this would typically line up with the creation date descending and the Id ascending. For more complex queries it would depend on the joins being performed. With regards to  post about  and the part about retaining reputation earned from deleted posts that have a score of 3 or better and were visible on the site for 60 days, does this also apply to self-deleted posts and will it continue to do so? I culled a few of my own answers over the weekend that were less than stellar, and my reputation dropped 1.8k, but the rep is back today after the changes were announced. I thought it would be useful to clarify that this also applies to self-deleted stuff. How to output MySQL query results in CSV format? Is there an easy way to run a MySQL query from the Linux command line and output the results in  format?  Here's what I'm doing now:  mysql -u uid -ppwd -D dbname &lt;&lt; EOQ | sed -e 's/        /,/g' | tee list.csv select id, concat("\"",name,"\"") as name from students EOQ   It gets messy when there are a lot of columns that need to be surrounded by quotes, or if there are quotes in the results that need to be escaped. I'm trying to connect to another computer in my house via ssh. Both computers have ubuntu and openssh installed. When I run the command "ssh username@ip" on terminal I'm asked for the user's password I'm trying to connect to. I type it but I get this error "Permission denied, please try again." I'm sure the password is correct, then why can't I access? When do we double the consonant before '-ing' affix? My son is learning how to spell. He is doing a good job listening to sounds and working out spelling that way (which doesn't work for many words, but at least a lot of common ones), but although he's gotten the -ing chunk, he frequently misses doubling letters in these words.  Is there a guideline for when the end consonant is doubled? He's working on these sorts of words:        riding   sitting   skating   writing   getting How to show that the nth power of a $n \times n$ nilpotent matrix equals to zero $A^n=0$ $A$ is a $n\times n$ matrix such that $ A^m = 0 $ for some positive integer $m$.   Show that $A^n = 0$.   My attempt: For $n &gt; m$, it's obvious since matrix multiplication is associative.  For $n &lt; m$, $A^n\times A^{m-n} = 0$; not sure what to do next. Also I know that $\det A = 0$. How can you change the href for a hyperlink using jQuery? Recently my paper is reviewed (by a professor from independent third party) and accepted by a journal. But, my employer allows me to publish this paper only without its name there.  Publishing house is expecting affiliation for each author, i.e. I can not leave affiliation as blank.   What should I write as the affiliation? How far into space does one have to travel to see the entire sphere of earth? Virgin Galactic will take passengers aboard SpaceShipTwo  above the surface of the earth. But from this altitude, passengers will only be able to see a certain segment of the curvature of the earth through .  How much further into space would SpaceShipTwo have to travel to give passengers a view of the entire sphere of earth through one of these windows? What is the difference between "getting robbed" and "getting mugged"? I can't seem to find the difference on the internet between "getting robbed" and "getting mugged". I would appreciate it if you could explain it to me. conversion of laplacian from cartesian to spherical coordinates Find the solution of following differential equation:     $$\frac{dy}{dx}=\frac{1}{xy(x^2 \sin (y^2)+1)}$$   Could someone hint me something to get through this problem? How do you use plural or singular form of an adjective? How do that charge gets transferred while rubbing? KDB: apply dyadic function across two lists Adding a loop cut to an object with a circular profile renders the object non-circular.  This is true for any object with a circular frame e.g. plain circles, UV-spheres, cylinders, cones, etc.  Top-left is the mesh of a plain circle with Subsurf modifier applied (bottom-left).  Notice how adding one additional vertex (top-right) makes the circle skewed (bottom-right). Is there a tool/transform/way to correct the circle? Knowing the solution to this should help solve the problem for all the aforementioned objects.  I tried selecting all points and applied the To Sphere transform in vain.  It didn't help. I thought putting the vertex r radius away from the circle's centre like the rest of the vertices will help, looks like it doesn't. I'm trying to make a map using the Javascript API.  I want to use my own basemap, but I can't find the most simple code to do this.  I always see something like this:    function init() {     map = new esri.Map("mapDiv", {       basemap: "satellite",       center: [-97.395, 37.537],       zoom: 11     });   But I don't want to use the ArcGIS online basemaps.  What is the code to make a map service I am hosting my basemap? Producing doc/docx from LaTeX Is there any way to produce doc/docx files from LaTeX? Launch an app from within another (iPhone) Is it possible to launch any arbitrary iPhone application from within another app?, For example in my application if I want the user to push a button and launch right into the Phone app (close the current app, open the Phone app).  would this be possible? I know this can be done for making phone calls with the tel URL link, but I want to instead just have the Phone app launch without dialing any specific number.
