  • Modify python USB device driver to only use vendor_id and product_id, excluding BCD

    - by Tony
    I'm trying to modify the Android device driver for calibre (an e-book management program) so that it identifies devices by only vendor id and product id, and excludes BCD. The driver is a fairly simply python plugin, and is currently set up to use all three numbers, but apparently, when Android devices use custom Android builds (ie CyanogenMod for the Nexus One), it changes the BCD so calibre stops recognizing it. The current code looks like this, with a simple list of vendor id's, that then have allowed product id's and BCD's with them: VENDOR_ID = { 0x0bb4 : { 0x0c02 : [0x100], 0x0c01 : [0x100]}, 0x22b8 : { 0x41d9 : [0x216]}, 0x18d1 : { 0x4e11 : [0x0100], 0x4e12: [0x0100]}, 0x04e8 : { 0x681d : [0x0222]}, } The line I'm specifically trying to change is: 0x18d1 : { 0x4e11 : [0x0100], 0x4e12: [0x0100]}, Which is, the line for identifying a Nexus One. My N1, running CyanogenMod 5.0.5, has the BCD 0x0226, and rather than just adding it to the list, I'd prefer to eliminate the BCD from the recognition process, so that any device with vendor id 0x18d1 and product id 0x4e11 or 0x4e12 would be recognized. The custom Android rom doesn't change enough for the specifics to matter. The syntax seems to require the BCD in brackets. How can I edit this so that it matches anything in that field?

  • Spring 3 simple extentionless url mappings with annotation-based mapping - impossible?

    - by caerphilly
    Hi, I'm using Spring 3, and trying to set up a simple web-app using annotations to define controller mappings. This seems to be incredibly difficult without peppering all the urls with *.form or *.do Because part of the site needs to be password protected, these urls are all under /secure. There is a <security-constraint> in the web.xml protecting everything under that root. I want to map all the Spring controllers to /secure/app/. Example URLs would be: /secure/app/landingpage /secure/app/edit/customer/{id} each of which I would handle with an appropriate jsp/xml/whatever. So, in web.xml I have this: <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/secure/app/*</url-pattern> </servlet-mapping> And in despatcher-servlet.xml I have this: <context:component-scan base-package="controller" /> In the Controller package I have a controller class: package controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.servlet.ModelAndView; import javax.servlet.http.HttpServletRequest; @Controller @RequestMapping("/secure/app/main") public class HomePageController { public HomePageController() { } @RequestMapping(method = RequestMethod.GET) public ModelAndView getPage(HttpServletRequest request) { ModelAndView mav = new ModelAndView(); mav.setViewName("main"); return mav; } } Under /WEB-INF/jsp I have a "main.jsp", and a suitable view resolver set up to point to this. I had things working when mapping the despatcher using *.form, but can't get anything working using the above code. When Spring starts up it appears to map everything correctly: 13:22:36,762 INFO main annotation.DefaultAnnotationHandlerMapping:399 - Mapped URL path [/secure/app/main] onto handler [controller.HomePageController@2a8ab08f] I also noticed this line, which looked suspicious: 13:25:49,578 DEBUG main servlet.DispatcherServlet:443 - No HandlerMappings found in servlet 'dispatcher': using default And at run time any attempt to view /secure/app/main just returns a 404 error in Tomcat, with this log output: 13:25:53,382 DEBUG http-8080-1 servlet.DispatcherServlet:842 - DispatcherServlet with name 'dispatcher' determining Last-Modified value for [/secure/app/main] 13:25:53,383 DEBUG http-8080-1 servlet.DispatcherServlet:850 - No handler found in getLastModified 13:25:53,390 DEBUG http-8080-1 servlet.DispatcherServlet:690 - DispatcherServlet with name 'dispatcher' processing GET request for [/secure/app/main] 13:25:53,393 WARN http-8080-1 servlet.PageNotFound:962 - No mapping found for HTTP request with URI [/secure/app/main] in DispatcherServlet with name 'dispatcher' 13:25:53,393 DEBUG http-8080-1 servlet.DispatcherServlet:677 - Successfully completed request So... Spring maps a URL, and then "forgets" about that mapping a second later? What is going on? Thanks.

  • OCR: How to improve accuracy - existing libraries for removing non-text 'furniture', shapes, etc to

    - by Rob
    I want to remove rectangles etc that enclose text in a screenshot image, so that I can perform optical character recognition to get accurate text from the screenshot. Background: I doing this to extract data from a legacy application for use with other applications. This is the only way to get at this data as associated files are in a closed, proprietary, binary format. I will be using AutoItScript to drive the application to show data in its UI, then I will screenshot this and feed this to tesseract. I've already had some success in automating the UI, and have been able to use tesseract to get plain ascii text out of the bitmap. There are several AutoItScripr forum articles discussing its use with tesseract/OCR but not specifically for my question. http://www.autoitscript.com/forum/index.php?s=6c32c3ece12756e635a619cdf175eff9&showforum=2 What I need to do There are thin, 1-pixel wide rectangles that closely enclose some text, when fed to tesseract, it sees them as I for example for a verticle line of the rectangle. Any thoughts on how to remove the rectangles, or best practices? I'm asking if there is a generic command line based toolset to overwrite rectangles, for example, in .png files. I could then pass the .png through this, then pass it to tesseract. Details on the tesseract release/setup I've used are as follows: Go here: http://code.google.com/p/tesseract-ocr/downloads/list - For the basic english generic character set to get Tesseract up and running and recognising your bitmapped text into ascii text, use tesseract-2.00.eng.tar.gz (current version at time of writing is: "English language data for Tesseract (2.00 and up) Jul 2007 989 KB 84845") Related questions I have already looked at on Stack Overflow http://stackoverflow.com/questions/1335581/how-to-give-best-chance-of-success-to-an-ocr-software http://stackoverflow.com/questions/2296568/analysis-and-transformation-of-the-image-on-the-basis-of-this-analysis-for-better http://stackoverflow.com/questions/2268028/reading-characters-off-of-the-screen In these, my question is not completely answered or a commercial solution is being sold. I do not want to consider a commercial solution at this stage.

  • Preserving URLs after CMS migration with redirect database and apache http?

    - by stwissel
    We will migrate an entire intranet from one CMS to another. All URLs will change in a non-predictable pattern, but I can capture a file with original,new URLs I can feed into anything. I have hundred thousands of URLs, not just a few hundred. What I would like to do: every URL that is not found (404) should be checked against the database and if a new URL found a 301/308 issued instead. Some trickery to suggest similar pages in the 404 message if the lookup was unsuccessful would be an added bonus. Is that the right approach or should I check redirection first all the time? How would I do that in Apache2? Is that a custom 404 module?

  • Strange. Asterisk key plays random Windows sound when pressed

    - by Charles
    This is a new one on me. When I press the "asterisk", or * button on my number pad (but not SHIFT+8), Windows makes either a "Exclamation" or "Windows ding" sound. I haven't noticed a pattern to which sound is made. Logitech K200 keyboard No special key mapping software or Logitech software running Realtek sound to stereo through optical cable. Visual Studio 2010, Chrome, Fiddler, WinRAR, Notepad++, and Dropbox running. No unusual behavior otherwise. A solution isn't terribly important but my curiosity is both piqued and stumped. This doesn't normally happen and nothing odd has taken place otherwise. Ideas?

  • I am trying to zip files individually, but the file type is unknown

    - by Jason Mander
    I am trying to zip some files with an unknown file type individually. I am using the following code in a batch script to do that: @ECHO OFF FOR %%A IN (bestbuy*nat*component.cpi*) DO "C:\Program Files\7-Zip\7z.exe" a -mx9 -m0=lzma2:d256m "%%~nA.7z" "%%A" The code will compress files individually ONLY if the file has an extension. Unfortunately the files that I have don't have any extension. In the code I am trying to zip files by doing a pattern match, the files are getting compressed into ONE file (which I do not want, I want each file compressed individually). Why does this code create separate zip files when the files have an extension (for example if I add .txt to the end of the files) and when there is no extension the code creates one zipped file. Can anyone please help me with the code to compress files with unknown file type so that each file gets compressed individually Your help would be greatly appreciated. Jason

  • How can I rewrite / redirect URL's in Glassfish V3?

    - by Jin Liew
    Hi, I'd like to simplify the URL's to access a Glassfish V3 application by removing file extensions and otherwise shortening URL's. I've already set my application as the default application, so that there is no need to include the context root in the URL. I'd like to: * Remove file extensions * Shorten the URL to files deep in the folder structure I'd like to do this using pattern matching rather than on a per file basis (Site is small at the moment but will change frequently and grow). Some examples of what I'd like to do: * foo.com/bar.html - foo.com/bar * foo.com/folder1/folder2/bar2.html - foo.com/bar2 Any help would be greatly appreciated. Thanks. Cheers, Jin

  • Ivy resolve not working with dynamic artifact

    - by richever
    I've been using Ivy a bit but I seem to still have a lot to learn. I have two projects. One is a web app and the other is a library upon which the web app depends. The set up is that the library project is compiled to a jar file and published using Ivy to a directory within the project. In the web app build file, I have an ant target that calls the Ivy resolve ant task. What I'd like to do is have the web app using the dynamic resolve mode during development (on developer's local machines) and default resolve mode for test and production builds. Previously I was appending a time stamp to the library archive file so that Ivy would notice changes in file when the web app tried to resolve its dependency on it. Within Eclipse this is cumbersome because, in the web app, the project had to be refreshed and the build path tweaked every time a new library jar was published. Publishing a similarly named jar file every time would, I figure, only require developers to refresh the project. The problem is that the web app is unable to retrieve the dynamic jar file. The output I get looks something like this: resolve: [ivy:configure] :: Ivy 2.1.0 - 20090925235825 :: http://ant.apache.org/ivy/ :: [ivy:configure] :: loading settings :: file = /Users/richard/workspace/webapp/web/WEB-INF/config/ivy/ivysettings.xml [ivy:resolve] :: resolving dependencies :: com.webapp#webapp;[email protected] [ivy:resolve] confs: [default] [ivy:resolve] found com.webapp#library;latest.integration in local [ivy:resolve] :: resolution report :: resolve 142ms :: artifacts dl 0ms --------------------------------------------------------------------- | | modules || artifacts | | conf | number| search|dwnlded|evicted|| number|dwnlded| --------------------------------------------------------------------- | default | 1 | 0 | 0 | 0 || 0 | 0 | --------------------------------------------------------------------- [ivy:resolve] [ivy:resolve] :: problems summary :: [ivy:resolve] :::: WARNINGS [ivy:resolve] :::::::::::::::::::::::::::::::::::::::::::::: [ivy:resolve] :: UNRESOLVED DEPENDENCIES :: [ivy:resolve] :::::::::::::::::::::::::::::::::::::::::::::: [ivy:resolve] :: com.webapp#library;latest.integration: impossible to resolve dynamic revision [ivy:resolve] :::::::::::::::::::::::::::::::::::::::::::::: [ivy:resolve] :::: ERRORS [ivy:resolve] impossible to resolve dynamic revision for com.webapp#library;latest.integration: check your configuration and make sure revision is part of your pattern [ivy:resolve] [ivy:resolve] :: USE VERBOSE OR DEBUG MESSAGE LEVEL FOR MORE DETAILS BUILD FAILED /Users/richard/workspace/webapp/build.xml:71: impossible to resolve dependencies: resolve failed - see output for details The web app resolve target looks like this: <target name="resolve" depends="load-ivy"> <ivy:configure file="${ivy.dir}/ivysettings.xml" /> <ivy:resolve file="${ivy.dir}/ivy.xml" resolveMode="${ivy.resolve.mode}"/> <ivy:retrieve pattern="${lib.dir}/[artifact]-[revision].[ext]" type="jar" sync="true" /> </target> In this case, ivy.resolve.mode has a value of 'dynamic' (without quotes). The web app's Ivy file is simple. It looks like this: <ivy-module version="2.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://ant.apache.org/ivy/schemas/ivy.xsd"> <info organisation="com.webapp" module="webapp"/> <dependencies> <dependency name="library" rev="${ivy.revision.default}" revConstraint="${ivy.revision.dynamic}" /> </dependencies> </ivy-module> During development, ivy.revision.dynamic has a value of 'latest.integration'. While, during production or test, 'ivy.revision.default' has a value of '1.0'. Any ideas? Please let me know if there's any more information I need to supply. Thanks!

  • IIS7 URL Rewrite for URL with &rsquo;

    - by blizz
    I'm trying to redirect the following URL in IIS7 using the URL Rewrite module: Category/Cat-3/Objectives-of-Pre-Maintenance/WHAT&rsquo;S-THE-STORY-ON-LOW-CARB-DIETS-AND-EXERCISE-.aspx but for the life of me I can not get it. I tried replacing the &rsquo; with an actual single quote, and that worked fine! But for the purpose of this redirect, I need the HTML code for the quote, and not the quote itself. Here is the rule from web config: <rule name="Redirect" patternSyntax="ECMAScript" stopProcessing="true"> <match url="^Category/Cat-3/Objectives-of-Pre-Maintenance/WHAT&amp;rsquo;S-THE-STORY-ON-LOW-CARB-DIETS-AND-EXERCISE-\.aspx" /> <conditions> <add input="{HTTP_HOST}" pattern="www.example.com" /> </conditions> <action type="Redirect" url="http://www.example.com/redirecturl/" appendQueryString="false" /> </rule> Any ideas would be very helpful! Thanks

  • Having issues with flickering output to TV from Windows 7 laptop

    - by Nimmy Lebby
    I cannot tell why this is happening. I cannot get a pattern as to when it happens. Sometimes, I watch entire Hulu content without any interruptions. Other times, it happens 2-3 times in a span of 3 minutes. Then it stops for 10-15 minutes. Lenovo T410s Integrated graphics: Intel HD Graphics (Driver=8.15.10.2253, Video BIOS=2026.1) TV is a Zenith (does not happen with other laptop so doubt it's TV) TV connected to laptop using HDMI-to-DVI cable (previously was connected directly via DVI but I bought a new cable and it's still happening) Anyone could help me troubleshoot this? I'd greatly appreciate it. If you need more information, I'll be glad to provide it.

  • Wildcards not being substituted

    - by user21463
    #!/bin/bash loc=`echo ~/.gvfs/*/DCIM/100_FUJI` rm -f /mnt/fujifilmA100 ln -s "$loc" /mnt/fujifilmA100 For some reason the variable * doesn't get substituted with the only possible value and gets given the value /home/chris/.gvfs/*/DCIM/100_FUJI. Does anyone have an idea of why? Please note: If global expansion fails, the pattern is not substituted. I ran the commands: chris@comp2008:~$ loc=`echo ~/.gvfs/*/DCIM/100_FUJI ` chris@comp2008:~$ echo $loc /home/chris/.gvfs/gphoto2 mount on usb%3A001,008/DCIM/100_FUJI So we can see the expansion should work I have now switched to using: loc = `find ~/.gvfs -name 100_FUJI ` I am just curious why it doesn't work as is. Debugging output using sh -x echo /home/chris/.gvfs/*/DCIM/100_FUJI loc=/home/chris/.gvfs/*/DCIM/100_FUJI rm -f /mnt/fujifilmA100 ln -s /home/chris/.gvfs/*/DCIM/100_FUJI/mnt/fujifilmA100

  • PostgreSQL server: 10k RPM SAS or Intel 520 Series SSD drives?

    - by Vlad
    We will be expanding the storage for a PostgreSQL server and one of the things we are considering is using SSDs (Intel 520 Series) instead of rotating discs (10k RPM). Price per GB is comparable and we expect improved performance, however we are concerned about longevity since our database usage pattern is quite write-heavy. We are also concerned about data corruption in case of power failure (due to SSDs write cache not flushing properly). We currently use RAID10 with 4 active HDDs (10k 146GB) and 1 spare configured in the controller. It's a HP DL380 G6 server with P410 Smart Array Controller and BBWC. What makes more sense: upgrading the drives to 300GB 10k RPM or using Intel 520 Series SSDs (240GB)?

  • Search files for text matching format of a Unix directory

    - by BrandonKowalski
    I am attempting to search through all the files in a directory for text matching the pattern of any arbitrary directory. The output of this I hope to use to make a list of all directories referenced in the files (this part I think I can figure out on my own). I have looked at various regex resources and made my own expression that seems to work in the browser based tool but not with grep in the command line. /\w+[(/\w+)]+ My understanding so far is the above expression will look for the beginning / of a directory then look for an indeterminate number of characters before looking for a repeating block of the same thing. Any guidance would be greatly appreciated.

  • IIS 7 URL rewrite rule

    - by Andrew
    Hello, guys! We have here to web servers behind a router - one IIS and one Tomcat (on different machines / IP addresses). The domain is pointing to out external IP, which is forwarded to IIS (internal IP 192.168.1.10 for example). I'm trying to do the following: when [www.]ourdomain.com is entered the default web site on IIS have to be loaded (this part is ok), but when test.ourdomain.com is entered I want to redirect this request to another web server (192.168.1.11 for example). I created a site "test" on IIS and it is displayed when test.ourdomain.com is entered. Then I tried to redirect it with following rule: Requested URL matches the pattern: * (using wildcards) Condition: {HTTP_HOST} matches test.ourdomain.com Action type: Rewrite Rewrite URL: http://192.168.1.11/{R:0} but when I try to load test.ourdomain.com now I get IIS's error 404 page. Obviously I'm wrong :-) How can I do such a redirect?

  • Why would the IIS UrlRewrite module continue redirecting requests after the rule is removed?

    - by Jon Norton
    Our application uses the IIS UrlRewrite module to temporarily redirect requests during upgrades to a maintenance site. We have seen a few instances where even though the redirect rule has been removed, the server continues to redirect all requests according to the removed rule. There does not seem to be any pattern with this, and has only occurred once or twice. We have taken the following steps to try and determine the cause of this behavior. Verified that the original rule was a 307 temporary redirect Requested the application from machines that had never requested it before Used a different browser Added and removed a dummy rule from the IIS management console Checked the http kernel cache using netsh http show cachestate Modified the applicationHost.config file by hand (the rule was not still in the file, we just added a superfluous space) In the past when this has happened, we have been able to restart IIS and it solves the problem but that is not always an option and we really want to figure out what the root cause is. How or why would UrlRewrite be caching the response and not responding to configuration changes?

  • Designing interfaces: predict methods needed, discipline yourself and deal with code that comes to m

    - by fireeyedboy
    Was: Design by contract: predict methods needed, discipline yourself and deal with code that comes to mind I like the idea of designing by contract a lot (at least, as far as I understand the principal). I believe it means you define intefaces first before you start implementing actual code, right? However, from my limited experience (3 OOP years now) I usually can't resist the urge to start coding pretty early, for several reasons: because my limited experience has shown me I am unable to predict what methods I will be needing in the interface, so I might as well start coding right away. or because I am simply too impatient to write out the whole interfaces first. or when I do try it, I still wind up implementing bits of code already, because I fear I might forget this or that imporant bit of code, that springs to mind when I am designing the interfaces. As you see, especially with the last two points, this leads to a very disorderly way of doing things. Tasks get mixed up. I should draw a clear line between designing interfaces and actual coding. If you, unlike me, are a good/disciplined planner, as intended above, how do you: ...know the majority of methods you will be needing up front so well? Especially if it's components that implement stuff you are not familiar with yet. ...resist the urge to start coding right away? ...deal with code that comes to mind when you are designing the interfaces? UPDATE: Thank you for the answers so far. Valuable insights! And... I stand corrected; it seems I misinterpreted the idea of Design By Contract. For clarity, what I actually meant was: "coming up with interface methods before implementing the actual components". An additional thing that came up in my mind is related to point 1): b) How do you know the majority of components you will be needing. How do you flesh out these things before you start actually coding? For arguments sake, let's say I'm a novice with the MVC pattern, and I wanted to implement such a component/architecture. A naive approach would be to think of: a front controller some abstract action controller some abstract view ... and be done with it, so to speak. But, being more familiar with the MVC pattern, I know now that it makes sense to also have: a request object a router a dispatcher a response object view helpers etc.. etc.. If you map this idea to some completely new component you want to develop, with which you have no experience yet; how do you come up with these sort of additional components without actually coding the thing, and stuble upon the ideas that way? How would you know up front how fine grained some components should be? Is this a matter of disciplining yourself to think it out thoroughly? Or is it a matter of being good at thinking in abstractions?

  • Beginner video capture and processing/Camera selection

    - by mattbauch
    I'll soon be undertaking a research project in real-time event recognition but have no experience with the programming aspect of video capture (I'm an upperclassman undergraduate in computer engineering). I want to start off on the right foot so advice from anyone with experience would be great. The ultimate goal is to track events such as a person standing up/sitting down, entering/leaving a room, possibly even shrugging/slumping in posture, etc. from a security camera-like vantage point. First of all, which cameras/companies would you recommend? I'm looking to spend ~$100, more if necessary but not much. Great resolution isn't a must, but is desirable if affordable. What about IP network cameras vs. a USB type webcam? Webcams are less expensive, but IP cameras seem like they'd be much less work to deal with in software. What features should I look for in the camera? Once I've selected a camera, what does converting its output to a series of RGB bitmaps entail? I've never dealt with video encoding/decoding so a starting point or a tutorial that will guide me up to this point would be great if anyone has suggestions. Finally, what is the best (least complicated/most efficient) way to display video from the camera plus my own superimposed images (boxes around events in progress, for instance) in a GUI application? I can work on any operating system in any language. I have some experience with win32 GUIs and Java GUIs. The focus of the project is on the algorithm and so I'm trying to get the video capture/display portion of the app done cleanly and quickly. Thanks for any responses!!

  • Identical traffic

    - by Walter White
    Hi all, I am running an application server and logging all requests for analysis purposes later. One interesting trend I noticed last night was, I had a visitor from Texas on FIOS share identical traffic with bluecoat in California. What would cause the traffic to be identical? For every request the visitor made, bluecoat made one subsequently within milliseconds of his request. If it is caching, why would there be identical requests? Wouldn't it go through the cache / proxy on their end, and I would only see the proxied request? I'm just curious, this is an interesting pattern that shows similarities of a DDoS attack, but with far fewer resources. Is it possible that the visitor had malware on their computer? Any other ideas? Walter

  • Can't run my servlet from tomcat server even though the classes are in package

    - by Mido
    Hi there, i am trying to get my servlet to run, i have been searching for 2 days and trying every possible solution and no luck. The servet class is in the appropriate folder (i.e under the package name). I also added the jar files needed in my servlet into lib folder. the web.xml file maps the url and defines the servlet. So i did everything in the documentation and wt people said in here and still getting this error : type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception javax.servlet.ServletException: Error instantiating servlet class assign1a.RPCServlet org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:108) org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:558) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:379) org.apache.coyote.http11.Http11AprProcessor.process(Http11AprProcessor.java:282) org.apache.coyote.http11.Http11AprProtocol$Http11ConnectionHandler.process(Http11AprProtocol.java:357) org.apache.tomcat.util.net.AprEndpoint$SocketProcessor.run(AprEndpoint.java:1687) java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) java.lang.Thread.run(Thread.java:619) root cause java.lang.NoClassDefFoundError: assign1a/RPCServlet (wrong name: server/RPCServlet) java.lang.ClassLoader.defineClass1(Native Method) java.lang.ClassLoader.defineClassCond(ClassLoader.java:632) java.lang.ClassLoader.defineClass(ClassLoader.java:616) java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) org.apache.catalina.loader.WebappClassLoader.findClassInternal(WebappClassLoader.java:2820) org.apache.catalina.loader.WebappClassLoader.findClass(WebappClassLoader.java:1143) org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1638) org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1516) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:108) org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:558) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:379) org.apache.coyote.http11.Http11AprProcessor.process(Http11AprProcessor.java:282) org.apache.coyote.http11.Http11AprProtocol$Http11ConnectionHandler.process(Http11AprProtocol.java:357) org.apache.tomcat.util.net.AprEndpoint$SocketProcessor.run(AprEndpoint.java:1687) java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) java.lang.Thread.run(Thread.java:619) note The full stack trace of the root cause is available in the Apache Tomcat/7.0.5 logs.

  • Parsec: backtracking not working

    - by Nathan Sanders
    I am trying to parse F# type syntax. I started writing an [F]Parsec grammar and ran into problems, so I simplified the grammar down to this: type ::= identifier | type -> type identifier ::= [A-Za-z0-9.`]+ After running into problems with FParsec, I switched to Parsec, since I have a full chapter of a book dedicated to explaining it. My code for this grammar is typeP = choice [identP, arrowP] identP = do id <- many1 (digit <|> letter <|> char '.' <|> char '`') -- more complicated code here later return id arrowP = do domain <- typeP string "->" range <- typeP return $ "("++domain++" -> "++range++")" run = parse (do t <- typeP eof return t) "F# type syntax" The problem is that Parsec doesn't backtrack by default, so > run "int" Right "int" -- works! > run "int->int" Left "F# type syntax" unexpected "-" expecting digit, letter, ".", "`" or end of input -- doesn't work! The first thing I tried was to reorder typeP: typeP = choice [arrowP, identP] But this just stack overflows because the grammar is left-recursive--typeP never gets to trying identP because it keeps trying arrowP over and over. Next I tried try in various places, for example: typeP = choice [try identP, arrowP] But nothing I do seems to change the basic behaviours of (1) stack overflow or (2) non-recognition of "-" following an identifier. My mistake is probably obvious to anybody who has successfully written a Parsec grammar. Can somebody point it out?

  • "mv: cannot stat file" in for loop

    - by F.C.
    I wanted to rename a lot of files with a pattern so I tried this for loop: $ for f in *; do mv \""$f"\" \""HouseMD-S06E${f#*Episode }"\"; done But I got this error: mv: cannot stat `"House MD Season 6 Episode 01 - Broken (Parts 1 & 2).avi"': No such file or directory So what I did was echo the mv commands to a file like this: $ for f in *; do echo mv \""$f"\" \""HouseMD-S06E${f#*Episode }"\">>mv.txt; done And the run the file with source. Any ideas why the first for didn't work and how can I fix it?
