  • Is there a better way than a sequence of if's to handle events?

    - by Matt
    I recently ran across several objects implemented to handle events with a hard coded mapping using this pattern: public void handleEvent(Event event) { if(event.getCode() == SOME_STATIC_EVENT) doSomething(event); if(event.getCode() == ANOTHER_STATIC_EVENT) doSomethingElse(event); } where doSomething functions are implemented as methods of the same class. In hopes of striving for looser coupling, how would you suggest abstracting out this pattern? Also, what's the best approach for mapping 0..N functions to a fired event?

  • how to upload a audio file using REST webservice in Google App Engine for Java

    - by sathya
    Am using google app engine with eclipse IDE and trying to upload a audio file. I used the File Upload in Google App Engine For Java and can able to upload the file successfully. Now am planning to use REST web service for it. I had analyzed in developers.google but i failed. Can anyone suggest me how to implement REST Web services in google app engine using Eclipse. The code google provided is shown below, // file Upload.java public class Upload extends HttpServlet { private BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService(); public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException { Map<String, BlobKey> blobs = blobstoreService.getUploadedBlobs(req); BlobKey blobKey = blobs.get("myFile"); if (blobKey == null) { res.sendRedirect("/"); } else { res.sendRedirect("/serve?blob-key=" + blobKey.getKeyString()); }}} // file Serve.java public class Serve extends HttpServlet { private BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService(); public void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException { BlobKey blobKey = new BlobKey(req.getParameter("blob-key")); blobstoreService.serve(blobKey, res); }} // file index.jsp <%@ page import="com.google.appengine.api.blobstore.BlobstoreServiceFactory" %> <%@ page import="com.google.appengine.api.blobstore.BlobstoreService" %> <% BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService(); %> <form action="<%= blobstoreService.createUploadUrl("/upload") %>" method="post" enctype="multipart/form-data"> <input type="file" name="myFile"> <input type="submit" value="Submit"> </form> // web.xml <servlet> <servlet-name>Upload</servlet-name> <servlet-class>Upload</servlet-class> </servlet> <servlet> <servlet-name>Serve</servlet-name> <servlet-class>Serve</servlet-class> </servlet> <servlet-mapping> <servlet-name>Upload</servlet-name> <url-pattern>/upload</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>Serve</servlet-name> <url-pattern>/serve</url-pattern> </servlet-mapping> Now how to provide a rest web service for the above code.

  • browser instant updates with ajax/jquery

    - by wcpro
    I'm trying to reverse engineer how facebook handles their notifications, where when you get a message you get instantly notified via the browser. I've fiddled with it for a little bit and realized that there is always a pending GET request "listening" if you will to some sort of update from the server. This appears to be some sort of observer pattern. I was just wondering if this pattern was documented somewhere.

  • Match multiple terms within <body> tags

    - by Jeepstone
    I've want to match any occurrence of a search term (or list of search terms) within the tags of a document. My current solution uses preg (within a Joomla plugin) $pattern = '/matchthisterm/i'; $article->text = preg_replace($pattern,"<span class=\"highlight\">\\0</span>",$article->text); But this replaces everything within the HTML of the document so I need to match the tags first. Is this even the best way to achieve this?

    On the iPhone, how could I achieve the same tiled background effect? For example, I have an pattern image which I want to repeat only horizontally. Would I have to go the route in -drawRect: by myself and loop over to draw the pattern, or is there a convenient method to do that?

  • Using java provided parameters into xpath function while applying xslt transformation

    - by filmac
    I'm working at a java application that performs some xslt transformation. I would like to match nodes into the xslt document, using a parameter provided by java. Which is the right way to do something like: <xsl:template match="//m:properties/*[contains($pattern,name())]"> because when I launch my application, it claims it's not able to compile the stylesheet, since pattern is not defined but I'm setting it using the setParameter method and I was able to use another parameter defined in the same way but in a different context. Thanks in advance Fil

  • grep is inconsistently defaulting to grep -P?

    - by Sammitch
    I have a script that does some housekeeping that works perfectly well when invoked from an interactive shell, but did nothing when invoked by cron. To troubleshoot this I started a shell with a 'blank' environment with the command: env -i /bin/bash --noprofile --norc Using this blank env I've dug into my script and found that the following grep will not match any files: grep -il "^ws_status\s*=\s*[\"']remove[\"']$" However, when run from an interactive shell the command will return the filenames of the matching files. As a note, the expression is matching lines like: WS_STATUS = "remove" Through trial-and-error I discovered that adding -P to the options [Perl regex] the command started working normally in the 'blank' shell. However, I have no idea why my login shell appears to be defaulted to grep -P. There is only one grep binary, /bin/grep There are no aliases defined for grep=pgrep or grep="grep -P" There is no env variable GREP_OPTIONS defined. What's the deal here? Note: OS is RHEL v5.10, Bash is v3.2.25, grep is v2.5.1

  • How do I troubleshoot a "Bad Request" in Apache2?

    - by Nick
    I have a PHP application that loads for all URLs except the home page. Visiting "https://my.site.com/" produces a "Bad Request" error message. Any other URL, for example, "https://my.site.com/SomePage/" works just fine. It's only the home page that does not work. All pages use mod_rewrite and get routed through a single dispatch script, Director.php. Accessing Director.php directly also produces the "Bad Request" error. BUT- ALL of the other requests go through Director, and they all work just fine, (excluding the home page), so it can't be an issue with the Director.php script? OR can it? I'm not seeing anything in the Apache2 error log, and I'm not seeing any PHP errors in the PHP Error log. I've tried changing the first line of Director.php to read: echo 'test'; exit(); But I still get a "Bad Request". This is the rewrite log for a request to the home page: 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da48b28/initial] (2) init rewrite engine with requested uri / 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da48b28/initial] (3) applying pattern '^/([a-zA-Z0-9\-\_]+)/$' to uri '/' 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da48b28/initial] (3) applying pattern '^/([a-zA-Z0-9\-\_]+)/([a-zA-Z0-9\-\_]+)/$' to uri '/' 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da48b28/initial] (1) pass through / 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da5a298/subreq] (2) init rewrite engine with requested uri /Director.php 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da5a298/subreq] (2) rewrite '/Director.php' - '-[L,NC]' 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da5a298/subreq] (3) applying pattern '^/([a-zA-Z0-9\-\_]+)/$' to uri '-[L,NC]' 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da5a298/subreq] (3) applying pattern '^/([a-zA-Z0-9\-\_]+)/([a-zA-Z0-9\-\_]+)/$' to uri '-[L,NC]' 123.123.123.123 - - [18/Feb/2011:05:38:49 +0000] [my.site.com/sid#7f273d77cb80][rid#7f273da5a298/subreq] (2) local path result: -[L,NC] Apache2 Access Log my.site.com:443 123.123.123.123 - - [18/Feb/2011:05:44:19 +0000] "GET / HTTP/1.1" 400 3223 "-" "Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.8) Gecko/20100723 Ubuntu/10.04 (lucid) Firefox/3.6.8" Any ideas?

  • How can I tell if my Amazon Windows instance was an SQL Server AMI?

    - by Aligma
    I want to purchase some reserved instances, because I have several instances already created and running 24 hours a day. When I go to purchase a Windows instance, I can see 3 options, Windows Windows with SQL Server Standard Windows with SQL server Web I don't know which of these was used to create the original instance. Is there a way I can find out? My assumptions: the instance type is is important because as far as I understand, the way to purchase a reserved instance is to first have a running instance, and then purchase a matching reserved instance. The reserved instance is not itself a new machine, but a kind of contract between you and Amazon to pay for an instance for 1 or 3 years, at a discounted rate. The contracted, reserved instance will "offset" one matching running instance where they have the same size and platform. Please feel free to correct me if these assumptions are incorrect.

  • apply seach criteria to whole cells

    - by Tom
    I am trying to use MATCH() and/or LOOKUP() in LibreOffice Calc. I have the "Search criteria = and < must apply to whole cells" and the "Enable regular expressions in formulas" options selected. The item I am looking for is a multi word string. How do I provide a search criteria as a cell reference (E3) in to LOOKUP(E3, B1:B20, C1:C20) and have it match the value in B1:B20 EXACTLY? Right now it is matching partial strings rather than matching the cell values exactly.

  • Criteria strings, how many different criteria can be entered to retrieve specific data?

    - by Janet
    For our membership database we are currently using an old DOS program "Arclist". The program is old but the one feature we desperately need in a database program is to be able to enter multiple criteria at one time for more of a "one time" extraction of the data meeting all the various criteria entered in what I call a "criteria string". An example may be extracting only those records with zip codes matching (67893, 54235, 54323, 54201, 54302, 54303, 54301, 67894, 67895). Another set of criteria might be to omit records, not equal to, one type of criteria in one field and also extract records matching criteria in another field. So we would want records "not equal to" in one field, but whose information equals requested information in another field.

  • Webcam microphone input in Gnome/pulseaudio

    - by sdaau
    Just got a "Trust" webcam, which gets recognized on my Ubuntu Lucid. It has a built in microphone - which also gets recognized - however, I cannot really get it to act as the system microphone input? Here are some screenshots of what is shown by gnome-volume-control: The default window shows Trust webcam - which has two profiles: "Analog Mono Input" and "Off" - of course, I have it on "Analog Mono Input": However, on the "Input" tab - there is no matching "device for sound input" - neither a matching connector: Then I installed pavucontrol - but that doesn't show that much more; it tells first that gnome-volume-control reads from "Internal Audio Analog Stereo": Then in "Input devices" tab, there is again nothing resembling the mic input from webcam: Finally, under "Configuration" tab, the "Trust" webcam shows, but even if its profile is on "Analog Mono Input", nothing much happens:   So, does anyone know how I could get this webcam microphone to be recognized as the system input? Many thanks in advance for any answers, Cheers!

  • International Dvorak keyboard doesn't trigger hot-keys

    - by akurtser
    I'm using the Engilsh-Dvorak keyboard-layout; My second keyboard language is Hebrew, which has nothing to do with Dvorak but the hot keys (e.g if I'm writing a document in Hebrew and want to make some bold text using Ctrl+b). The default Hebrew keyboard that comes with Windows (7 and below) has a shift mode which matches each Hebrew character with its matching English QWERTY character ). Obviously I'd want to use the Dvorak corresponding key rather than the QWERTY one, so I created a Hebrew-Dvorak keyboard with a software called Keyboard Layout Manager (KLM) which creates new keyboard layouts DLLs. It works just fine for the shift key, however, Ctrl-key triggered hot-keys (e.g Ctrl+l in FF) are being matched to the corresponding QWERTY key. I've examined the properly working English-Dvorak layout using KLM and in it's "Ctrl+ pressed" view, there isn't any character that's matched to any key but still I tried to encode the Hebrew Ctrl+ pressed keys to work with their matching Dvorak keys, yet it had no effect.

  • Highlight identical strings in vi(m)

    - by Boldewyn
    One feature of Notepad++, which I find really useful and haven't found elsewhere, is the highlighting of other text that is identical to the one currently selected. Is there something similar possible with vi(m)? (Of course, there is. But how do I achieve it?) That is, any of those: If I am in Visual Mode and have text selected: Highlight identical text If I have searched /foo, highlight all instances of foo. If I am at the beginning of a string (series of characters, numbers or underscores), highlight all other matching strings (prefered solution). The last one is similar to the closing parentheses matching and IMHO the most useful. Edit: For my second use case, I found a solution (that is, Google found it...): :set hls However, the others remain.

  • robots.txt file with more restrictive rules for certain user agents

    - by Carson63000
    Hi, I'm a bit vague on the precise syntax of robots.txt, but what I'm trying to achieve is: Tell all user agents not to crawl certain pages Tell certain user agents not to crawl anything (basically, some pages with enormous amounts of data should never be crawled; and some voracious but useless search engines, e.g. Cuil, should never crawl anything) If I do something like this: User-agent: * Disallow: /path/page1.aspx Disallow: /path/page2.aspx Disallow: /path/page3.aspx User-agent: twiceler Disallow: / ..will it flow through as expected, with all user agents matching the first rule and skipping page1, page2 and page3; and twiceler matching the second rule and skipping everything?
