Set "this" variable easily? bounding a $C^1$ function that upholds $f'(t)\leq 1-f(t)^2$ Where is the precmd command in android? I'm kind of used to linux. I'm using Busybox from the Busybox Free installer, with Busybox 1.21.0-Stericson. Trying to chance my shell to the Busybox shell using busybox ash gives the following error after every single command:  ash: precmd: not found echo $PS1 $(precmd)$USER@$HOSTNAME:${PWD: -?} $    I tried to go back to the normal shell and find out WHERE precmd is:  which precmd   It just changes the prompt to have "1|" in front of it, without giving me WHERE it is. I found a solution , but have no idea where to put it. I'm basically trying to do the same as  (make Busybox shell the default). Does the Lunatic Cultist spawn on iPad?

Prove that $R$ is a field.   Help me some hints.  Thanks a lot. Show every nonempty compact Hausdorff space is not the countable union of nowhere dense sets I know this proof is somewhat similar, or related to the Baire's Category Theorem but I can't seem to figure out how to do it.  The Baire Category theorem asserts that if X is a complete metric space or a locally compact Hausdorff space (my case), then the complement of a countable union of nowhere dense sets is always nonempty.  How can I use this on the proof? How do I install a Fortran 77 compiler? I have just installed 12.04 LTS on my laptop and I'm kinda new in this. I am required to write some program in Fortran 77 and I need a Fortran 77 compiler. I have tried installing g77 as described in the Ubuntu website but was unable to do so. I have typed in the following in terminal:  sudo apt-get install g77   and get the following:  Reading package lists... Done Building dependency tree        Reading state information... Done Package g77 is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source  E: Package 'g77' has no installation candidate   May I know what is the problem? I have tried searching g77 in the software center but apparently it is not there. Does this mean it is not available for 12.04?  I'm currently using an Asus K43S laptop with Intel Core i5-2450M processor and my Ubuntu is installed alongside Windows. Other word for person who does something to others but does'nt like it done to them This is a duplicate question but has still not been answered for me. I'm so close to the exact word - I know there is one out there - but the closest word I can find is a hypocrite --     a person who claims to have certain moral principles or beliefs but behaves in a way that shows they are not sincere.    The word I'm looking for is a person who does not claim things, but does thing to another and they consider it wrong or immoral to have done to them. What causes close votes to be annotated with "(deleted)"? Automatically update field value in one column based on change to another column in same table? When editing I want to be able to change the attributes of one field and upon doing this allow for the automatic update of another field in the same attribute table.   Essentially I have one layer with a code, description and legend information.   I would like to be able to edit the code and have the description and the legend information update with this edit with its correct description and legend information.   Is there any way to do this within ArcMap's tools or an associated script? Because of  I'd like to prevent apt-get upgrade and Update Manager from updating the "libgtk2.0-0" package.   How can this be achieved? Adding curved features to map with ArcGIS API for JavaScript? I've tried without much success to add a curved line feature to the ArcGIS JavaScript map.    I created a polygon with a curved edge in ArcMap:   However, when I load this same feature in the web API, it becomes segmented:   The problem started when I tried to create a curved feature from the JavaScript API itself, which only seems to allow full circle features (not circular arcs).  This makes me think that curves are still unsupported in the JavaScript API. Do you know any way around this? Do you have any other ideas on alternatives I can use to create and correctly view curved features? Subsetting a 2D numpy array How do I remap certain keys or devices? How do I install VMware player on a Mac os X? I went to their site, and downloaded a .bundle which automagically turned into a .txt file after downloading.   Long story short, I can't run the txt file because I guess Mountain Lion Mac os X isn't a strict Linux box and is missing some core components to do that type of installation.  Does anyone know how to install VMware? Is there an upside down caret character? I have to maintain a large number of classic ASP pages, many of which have tabular data with no sort capabilities at all. Whatever order the original developer used in the database query is what you're stuck with.  I want to to tack on some basic sorting to a bunch of these pages, and I'm doing it all client side with javascript. I already have the basic script done to sort a given table on a given column in a given direction, and it works well as long as the table is limited by certain conventions we follow here.    What I want to do for the UI is just indicate sort direction with the caret character ( ^ ) and ... what?  Is there a special character that is the direct opposite of a caret?  The letter v won't quite cut it.  Alternatively, is there another character pairing I can use? How do I get the difference between two Dates in JavaScript? I'm creating an application which lets you define events with a time frame.  I want to automatically fill in the end date when the user selects or changes the start date.  I can't quite figure out, however, how to get the difference between the two times, and then how to create a new end Date using that difference. How to use numpad / on a keyboard without a numpad? I've just got into Blender, and I like it a lot. But as I just switched from a stationary computer to a MacBook, I've got some new problems regarding the numpad. I can use 1-9 perfectly, But I have no idea how to emulate buttons like / (used to enter local view). I've searched the web for an answer, but I can't find any.
