Should I be using &quot;who&quot; or &quot;whom&quot; in this sentence? How would I form the deep structure of this sentence? Is it &quot;These days, a stay at home person is not whom&quot;?
I can never figure out whether I should use who and whom. Most people use who for both colloquially, but some people say this is not correct.  What’s the rule for using who and whom correctly?
The problem from Burton: show that the equation $n^2 + (n+1)^2 = m^3$ has no solution in the positive integers.  So far, I can see that gcd($n$,$n+1$)$=1$ and $m \equiv_4 1$ and $m=a^2 + b^2$ for some integers a,b. I'm guessing I need to reach a contradiction.  At this point, I am stuck. Any hints? Is it possible to browse the internet from a laptop so that the web sites you visit think you are browsing from a mobile device?  Say I need to connect via a very low bandwidth connection and just using the mobile version of the site is sufficient?  Currently I'm using Vista and Firefox 3.5 I am trying to retrieve VersionData with a standard REST API call from a VisualForce Page a then upload it to a S3 bucket but end up with corrupted files. I believe this is an encoding problem on the client side as plain text or CSVs work like a charm. I can upload VersionData from Apex but there are heap and request size limitations so I need to send the data from the client.   This is the call and returned string, I tried changing mimeType and encoding on both sides (SF call and S3 upload) with no luck.   Any ideas how to properly process images or pdf files? Thanks a lot  THE PROBLEM IS NOW SOLVED  Files should not be treated as strings. I solved the problem by leaving jQuery's ajax as I did not succeed to request a response type. By switching to plain JS and making a GET call (XMLHttpRequest) with response type set to blob I received an Object, instead of a string. Base64 string can be then retreived using JS FileReader. Ubuntu won't boot because of lvmetad I've followed this tutorial to install Ubuntu 15.10:    After restarting my computer I got to the grub menu and chose Ubuntu. Shortly after that I got this error:  /run/lvm/lvmetad.socket: connect failed: No such file or directory WARNING: Failed to connect to lvmetad. Falling back to internal scanning.   These messages keep adding up on a black screen every second. After a while,  I get access to the initramfs ash console.  what am I doing wrong? When I'm going through a whole bunch of shots to determine which to delete and which to flag, it's fastest for me to just keep both hands on the keyboard.  However, if I want to zoom in to 100% on a picture and then pan to a specific area, it seems I can only get halfway there -- 'Z' to zoom, but then I'm stuck having to pick up the mouse to pan around.  I was excited to find page-up/page-down/home/end can be used, but they seem to exist to provide an exhaustive, linear scrolling of the image, panning top-to-bottom then left-to-right, without unconstrained 2d movement.  Is there some way to toggle the arrow keys so they can pan instead of navigate to the next/prev photo?  Something else?  Or am I out of luck? I can’t get used to the new Unity system. I’d like to move the left Unity panel to the bottom of screen (like Windows 7 – more similar is better).  But I can't find a way. Is it possible? Indirectly access environment variable Given I have in a bash script  ev=USER   How can I get the environment variable value for $USER using ev?  Tried naively doing:  echo ${"$"$ev}   which results in bad substitution.  I'd expect to get back whatever the value of $USER is. How to add http:// if it doesn't exist in the URL Is it possible to write some C or C++ code and compile to binaries, then use those binaries with php? Is it also possible to write a php library using C and C++ ?  If so, please tell how can I do so? Is there a word for two persons dodging each other on the street? Should I mention about my governmental-funded PhD scholarship which I don't want to use No, this is not a , nor is it a solicitation on  to backup or  and only a little bit about Where to backup and When to do it.  This is basically a strategy question: what, where and when all together. "How" is not really relevant: there are tons of back-up programs out there and they all do the same basic thing: make copies of data.  But the real question is: are these back-up programs making copies of the data important to you?  How should you install&amp;run Ubuntu while safeguarding your data?  There is no "one size fits all" when it comes to computers, Ubuntu versions or a backup strategy, therefore I've split this up into 5 basic user types with each their own answer:       (or you're running in UEFI mode!)   And as the above does not fit everyone, one for the impatient:   !    So click one of the above links and go to your user type!  P.S. If you're running a server farm and you've read this question so far, I'm sorry: this is about a single PC, not a network, nor a server farm. How many square meters "twenty feet square" is? One would assume it to be about 2 square meters, but this is obviously not the case. In fact, I'm reading Illium by Dan Simmons. A quote follows:     Much like the room they had faxed into, this space was windowless and about twenty feet square. But unlike the other room, this one was warm, lighted, and free of snow or ice. And unlike the other room, this one was almost filled with an oval metal machine about fifteen feet long.   By this description, "twenty feet square" seems to mean 20x20 feet aka 400 square feet or 40 square meters. Given that Dan Simmons is a renowned American writer, it's not likely that he just can't speak English correctly. So, who's right and who's wrong here? Careers ads break the Android app Clicking any Careers (or Jobs) ad in the Android app feed results in an instant crash for the Android App version 1.0.89. Isomorphism of quotient modules implies isomorphism of submodules? Let $A$ be a commutative ring, $M$ an $A$-module and $N_1, N_2$ two submodules of $M$.  If we have $M/N_1 \cong M/N_2$, does this imply $N_1 \cong N_2$?  This seems so trivial, but I just don't see a proof... Thanks! What are the limits on how I can cast, change, and retract votes? What limits are there on how I can vote?  How often can I vote? How do my votes become locked/unlocked? Very good linear algebra book. I plan to self-study linear algebra this summer. I am sorta already familiar with vectors, vector spaces and subspaces and I am really interested in everything about matrices (diagonalization, ...), linear maps and their matrix representation and eigenvectors and eigenvalues. I am looking for a book that handles every of the aforementioned topics in details. I also want to build a solid basis of the mathematical way of thinking to get ready to an exciting abstract algebra next semester, so my main aim is to work on proofs for somehow hard problems. I got Lang's "Intro. to Linear Algebra" and it is too easy, superficial.  Can you advise me a good book for all of the above? Please take into consideration that it is for self-study, so that it' gotta work on its own. Thanks. Inform new users if they can upvote an answer they accepted I surprisingly often stumble upon answers which were accepted but clearly not upvoted by the asker. For example, the answer has not received any upvotes at all or the asker’s vote count is zero. While I acknowledge that , most such cases happen with new users, who have only recently received the privilege to vote and who upvote after a friendly reminder.  Given the anonymity of votes and that I do not check the asker’s profile for every question with an accepted answer I stumbled upon, I assume that there is a huge dark figure for this phenomenon. Also, I naturally most often spot this on my own answers, which makes reminding the asker of their privileges somewhat awkward.  I thus propose that users which accept an answer are reminded by a pop-up that they can upvote it, if:   They haven’t already upvoted it. They have the reputation required for voting. They have cast less than a handful of votes.   I consider the latter criterion to be better than an upper reputation for which the message is displayed, since I know at least one user with several thousand reputation points, who has cast much less upvotes or votes on answers than he has accepted answers on some sites (not that his acceptance rate or general feedback on answers is spectacular). This is a batch file in Windows.  Here is my .bat file          @echo off copy "C:\Remoting.config-Training" "C:\Remoting.config"  "C:\ThirdParty.exe"   This works fine except the .bat file leaves the command window open the whole time the "ThirdParty" application is running. I need the command window to close.   I would use the short-cut for the application but I must be able to run this copy command first (it actually changes which data base and server to use for the application).    The ThirdParty application does not allow the user to change the source of the db or the application server.    We're doing this to allow users to change from a test environment to the production environment. Maintaining Units of measure across type converstions
