  • Given GPS coordinates, how do I find nearby landmarks or points-of-interest?

    - by stackoverflowuser2010
    I just bought a Google Nexus One smartphone, and I want to write a small Android application for fun. Suppose I can get my current GPS coordinates, so then how can I programmatically find nearby landmarks or points-of-interest within some radius? Is there an API to get GPS geo-tagged landmarks, like in Google Earth's database? For example, if I'm in downtown Chicago, my program would point me to all the "tourist" things to visit in that city. Ideally, it would all run on my smartphone, but if necessary, I can have the smartphone query a webserver, which would then run more queries.

  • Generate colour palette from uploaded image

    - by greenie
    Just for fun I've been looking at how to use the GD library to create a colour palette from an image. So far I've used GD to resize a user uploaded image to an appropriate size for displaying on a webpage. Now I'd like to be able to get about five or so different colours from the image that represent the range of colours present in it. Once I've done that I'd like to generate a complementary palette based upon those colours, which I can then use to colour different elements on the page. Any help I can get about how I would find the initial colour palette would be much appreciated!

  • Is it possible to change a exe's icon without recompiling it?

    - by Microkernel
    Hi all, I have lot of executable that I have compiled (long time back) for many of which I don't have sourcecode now. But when I compiled them I didn't put any icons for them, so they all look like same dull, bald default icon. So my questions are, (1) is it possible for me to write a software that can change the resources section of the exe and change its looks? If so, can anyone plz point me to the location where its explained? (I am a beginner, I have no idea on the exe format and all) Also its fun to keep changing Icons without having the pain of recompiling everything just for the icon change... (2) This is raises a natural converse question, Is it similarly possible to zap out the icon used by some file and use it for some other file? (If so, plz point me to location where I can get some details. I am a C/C++ developers and I am looking for solution on Windows Platform... Regards, MicroKernel

  • Make a function which returns the original list except the argument

    - by Alex
    I want make a function which takes a list of string and a string and returns NONE if there is no string in the string list, otherwise it returns SOME of the list of string which is the same as the original list of string except it doesn't contain the initial string (pattern): fun my_function (pattern, source_list) = case source_list of [] => NONE | [x] => if pattern = x then SOME [] else NONE | x::xs => if pattern = x then SOME (xs) else SOME (x) :: my_function (pattern, xs) (* this is wrong, what to do here?*) val a = my_function ("haha", ["12", "aaa", "bbb", "haha", "ccc", "ddd"]) (* should be SOME ["12", "aaa", "bbb", "ccc", "ddd"]*) val a2 = my_function ("haha2", ["123", "aaa", "bbb", "haha", "ccc"]) (*should be NONE*) val a3 = my_function ("haha3", ["haha3"]) (* should be SOME []*) I'm confused by the 3rd case: x::xs => .... What should do there? Note that I'd like not to use any sml library function.

  • I want to create an Android App that checks a website like Woot

    - by tim
    Im new to android and thought it would be fun to develop an app that goes out and checks woot.com. The idea I came up with is for the app to be a widget that refresh woot.com once a day and displays a picture of the item and price. If the widget is clicked on it would open the browser to woot.com. In theory this seems like it would be easy but Im having trouble figuring out where to begin. Any help would be appreciated. Thanks Tim

  • css, jquery issue

    - by wadada
    I was playing with Infogrid on my site. I added a header, a footer and added some text on the last block of iron man. As you can see the footer doesn't show up and the text of the last block is cut off. Now if you remove overflow:hidden; on the body, html the footer shows up but the text is still cut off. Any idea on how this the footer could show up without the scrollbar (so overflow:hidden; has to stay) and how to get the text of the last block to show up entirely? Thanks in advance and have fun :) wadada

  • Understanding the Unix file system and ruby installs without Sudo

    - by JZ
    I'm trying to comprehend the Unix file system on my OSX. I'm following wikipedia Filesystem Hierarchy Standard. I understand when I install ruby gems I must use the command sudo gem install but if I omit sudo, problems may occur. Where are gems installed within the file system when I omit sudo? How can I delete these gems? A Fun side question: When I enter cd ~/.gem my terminal is directed to .gem user$, When I enter cd ~/ and list folders using the ls command I can't find a .gem folder. Where is the .gem folder? How does this fit into the Filesystem?

  • Python: re-initialize a function's default value for subsequent calls to the function.

    - by Peter Stewart
    I have a function that calls itself to increment and decrement a stack. I need to call it a number of times, and I'd like it to work the same way in subsequent calls but, as expected, it doesn't re-use the default value. I've read that this is a newbie trap and I've seen suggested solutions, but I haven't been able to make any solution work. It would be nice to be able to "fun.reset" def a(x, stack = [None]): print x,' ', stack if x > 5: temp = stack.pop() if x <=5: stack.append(1) if stack == []: return a(x + 1) print a(0) print a(2) #second call print a(3) #third call I expected this to work, but it doesn't. print a(0, [None]) print a(2, [None]) #second call print a(3, [None]) #third call Can I reset the function to it's initial state? Any help would be appreciated.

  • URL encoded POST bad practice?

    - by StackedCrooked
    I am (just for fun) trying to implement a High Score web-service. I would like it be compatible with REST principles. I want to be able to add a new highscore using url parameters like this http://mydomain.com/hs/add&name=John&score=987. According to REST this must be done using a POST request. Which leads to empty POST request with all data contained in the URL parameters. Would this be considered a bad practice? Update Security is currently not a big concern.

  • What makes COBOL such a hated language?

    - by cable
    I'm rather young and so I haven't experienced the times when COBOL was still in use and even going mainstream, maybe you can help me out. Everywhere I go and surf I: Am getting told about how horrible COBOL is See sites making fun of COBOL Hear that I should be happy that I don't have to use COBOL, from older programmers See others make anti-COBOL-ist jokes I don't know much about COBOL, except that it is still used everywhere as many old systems haven't got refactored and that it is even still developed and managed. I have also looked at some COBOL code examples but it seems like they are as rare and expensive as unicorn blood. If you close this question or give me sarcastic, irrelevant answers I'll have to learn COBOL to find it out the hard way. I'm serious.

  • F# static member

    - by HeMan
    I was working through the PDC 2008 F# videos and seem to run into a problem type StockAnalyzer (lprices, days) = let prices = lprices | Seq.map snd | Seq.take days static member GetAnalyzers(tickers, days) = tickers | Seq.map loadPrices | Seq.map (fun prices - new StockAnalyzer(prices, days)) member s.Return = let lastPrice = prices |> Seq.nth 0 let startPrice = prices |> Seq.nth (days - 1) lastPrice / startPrice - 1. I am getting an error at the static. GetStockPrices.fs(31,6): error FS0010: Unexpected keyword 'static' in binding. Expected incomplete structured construct at or before this point or other token. Does anyone know if they have changed the syntax or can spot what I am doing wrong

  • Most efficient way to save tile data of an isometric game

    - by Harmen
    Hello, I'm working on an isometric game for fast browsers that support <canvas>, which is great fun. To save information of each tile, I use a two-dimensional array which contains numbers representing a tile ID, like: var level = [[1, 1, 1, 2, 1, 0], [0, 1, 1, 2, 0, 1], [0, 1, 1, 2, 1, 1]]; var tiles = [ {name: 'grass', color: 'green'}, {name: 'water', color: 'blue'}, {name: 'forest', color: 'ForestGreen'} ]; So far it works great, but now I want to work with heights and slopes like in this picture: For each tile I need to save it's tile ID, height and information about which corners are turned upward. I came up with a simple idea about a bitwise representation of all four corners, like this: 1011 // top, bottom and left corner turned up My question is: what is the most efficient way to save these three values for each cell? Is it possible to save these three values as one integer?

  • Guidelines for good webcrawler 'Etiquette'

    - by Harry
    I'm building a search engine (for fun) and it has just struck me that potentially my little project might wreak havok by clicking on ads and all sorts of problems. So what are the guidelines for good webcrawler 'Etiquette'? Things that spring to mind: Observe Robot.txt instructions Limit the number of simultaneous requests to the same domain Don't follow ad links? Stopping the crawler from clicking on ads - This one is particularly on my mind at the moment... how do i stop my bot from 'clicking' on ads? if it is going straight to the url in the ad is it counted as a click?

  • The sieve of Eratosthenes in F#

    - by IVlad
    I am interested in an implementation of the sieve of eratosthenes in purely functional F#. I am interested in an implementation of the actual sieve, not the naive functional implementation that isn't really the sieve, so not something like this: let rec PseudoSieve list = match list with | hd::tl -> hd :: (PseudoSieve <| List.filter (fun x -> x % hd <> 0) tl) | [] -> [] The second link above briefly describes an algorithm that would require the use of a multimap, which isn't available in F# as far as I know. The Haskell implementation given uses a map that supports an insertWith method, which I haven't seen available in the F# functional map. Does anyone know a way to translate the given Haskell map code to F#, or perhaps knows of alternative implementation methods or sieving algorithms that are as efficient and better suited for a functional implementation or F#?

  • How do people handle working with Code Names for their projects?

    - by Mark
    Hi All, Recently we started using some code names for several different types of prototype applications all following a theme. This made things a little more fun and was a great idea. The problem is that Im not too sure how people deal with migrating a codebase from "codename" state into version 1.0 state which may have a proper name... not something that a client really shouldnt see :) We are using Visual Studio at the moment, and I can see that you can change the assembly name, but there are references to the namespaces, etc... that would really be a large change to make. Do people both changing things like namespaces before the v1.0 release?

  • Parallel Programming. Boost's MPI, OpenMP, TBB, or something else?

    - by unknownthreat
    Hello, I am totally a novice in parallel programming, but I do know how to program C++. Now, I am looking around for parallel programming library. I just want to give it a try, just for fun, and right now, I found 3 APIs, but I am not sure which one should I stick with. Right now, I see Boost's MPI, OpenMP and TBB. For anyone who have experienced with any of these 3 API (or any other parallelism API), could you please tell me the difference between these? Are there any factor to consider, like AMD or Intel architecture?

  • Designing a service for consumption on multiple mobile platforms

    - by Nate Bross
    I am building and designing a (mostly) read-only interface to some data. I'll be uing ASP.NET MVC to build a psudo-restful API. I'm wondering if anyone can provide some resources for building full-client applications for various mobile platforms, iPhone, Android, Blackberry, Windows Mobile, etc. I'm thinking that serving up XML data is going to be the most simple and universal, but parsing XML in objective-C for example doesn't sound like fun to me, but maybe there are some good libaries out there to help ease this task? In other words, what formt will be the quickest to implement on the client side? Are there any JSON parsrs for iPhone or Android? I know there are .NET JSON parsers, but not sure about other platforms -- is ther another format that might better? Or should I stick with pure XML and deal with it on each platform differently?

  • Compressing plaintext in JavaScript?

    - by AgileMeansDoAsLittleAsPossible
    I have a simple Notepad-like web application I'm making for fun. When you save a document, the contents of a <textarea> are sent to the server via Ajax and persisted in a database. Let's just say for shits and giggles that we need to compress the contents of the <textarea> before sending it because we're on a 2800 baud modem. Are there JavaScript libraries to do this? How well does plain text compress in the first place?

  • Best way to choose a random file from a directory in a shell script

    - by jhs
    What is the best way to choose a random file from a directory in a shell script? Here is my solution in Bash but I would be very interested for a more portable (non-GNU) version for use on Unix proper. dir='some/directory' file=`/bin/ls -1 "$dir" | sort --random-sort | head -1` path=`readlink --canonicalize "$dir/$file"` # Converts to full path echo "The randomly-selected file is: $path" Anybody have any other ideas? Edit: lhunath makes a good point about parsing ls. I guess it comes down to whether you want to be portable or not. If you have the GNU findutils and coreutils then you can do: find "$dir" -maxdepth 1 -mindepth 1 -type f -print0 \ | sort --zero-terminated --random-sort \ | sed 's/\d000.*//g/' Whew, that was fun! Also it matches my question better since I said "random file". Honsetly though, these days it's hard to imagine a Unix system deployed out there having GNU installed but not Perl 5.

  • glDrawElements allocating memory and not releasing it

    - by Joshua Weinberg
    Using OpenGLES 1.1 on the iPhone 3G (device, not simulator), I do normal drawing fun. But at points during the run of the application I get giant memory spikes, after a lot of digging with instruments I have found that it is glDrawElements that is grabbing the memory. The buffer being allocated is 4 meg, which to me means its loading a texture into RAM, which I guess could be valid, but its never releasing this buffer, and is allocating multiple of them. How do I make sure that these buffers that GL is creating get destroyed, instead of just hanging around?

  • OpenExeConfiguration Path Issue

    - by Harry
    I'm trying to load an web.config from a server. Its placed at: \server\folders\web.config when i try this: ConfigurationManager.OpenExeConfiguration(@"\\server\folders\web.config"); it searches for: web.config.config and fails. ConfigurationManager.OpenExeConfiguration(@"\\server\folders\web"); it fails, because there is no folder \server\folders\web\ So i tried several things and it seems as its checking wether the file the path is pointing on exists, and afterwards it appliers a .config and gets the config file. Just for fun i created an web.loaders file, and a web.loaders.config file. with ConfigurationManager.OpenExeConfiguration(@"\\server\folders\web.local"); it loads the \server\folders\web.local.config perfectly, but throws Exceptions without the web.local file. So there a many ways to get this small thing loaded, but isn't there a more nice one than using a temp .web file or something? Any help i highly appreciated, yours Harry

  • How to Promote iPhone App

    - by Ricibald
    I published my app. I request a review to more than 150 sites but only 8 of them give me a (good) review. I can't reach the most famous blogs because I have to pay to bring on top of their queue. Now, my app seems to be nice but I have only 65 users playing it. This 65 users seems to really like it because I can see there are a lot of games played tracked in my stats. A lot of users say that my app is "fun like Doodle Jump and very addictive". So, what's the problem? Why only 65 people? In a word, how can simple games such "Doodle Jump" or "Flight Control" enter in top 10? What's their secret? What's my mistake? UPDATE: I have a site describing my app.

  • Considering getting into reverse engineering/disassembly

    - by Zombies
    Assuming a decent understanding of assembly on common CPU architectures (eg: x86), how can one explore a potential path (career, fun and profit, etc) into the field of reverse engineering? There is so little educational guides out there so it is difficult to understand what potential uses this has today (eg: is searching for buffer overflow exploits still common, or do stack monitoring programs make this obselete?). I am not looking for any step by step program, just some relevant information such as tips on how to efficiently find a specific area of a program. Basic things in the trade. As well as what it is currently being used for today. So to recap, what current uses does reverse engineering yield today? And how can one find some basic information on how to learn the trade (again it doesn't have to be step-by-step, just anything which can through a clue would be helpful).
