  • western digital caviar black. EXT4-fs error

    Recently I update my HDD on desktop machine, and bought WD Caviar Black.

One time, machine rebooted (not manually), when I turn it on, it runs fsck on /dev/sdc2 and fix some errors and some files are missing on /dev/sdc2 I'v check /dev/sdc2 for badblocks, it doesn't have it ( using e2fsck -c /dev/sdc2 ) Here is the output of fsck http://pastebin.com/D5LmLVBY What else I can do to understand what's wrong here? BTW for /dev/sdc1 no message like that, in kern.log Linux version: 3.3.0 Distributive: Debian wheezy

  • Can't get my object to point at the mouse.

    - by melignus
    I'm using a combination of SDL and OpenGL in a sort of crash course project to teach myself how this all works. I'm really only interested in OpenGL as a way to use acceleration in 2D games so I just need this to work in a 2D plane. I have been having a lot of problems today with my current issue, I would like an object to point towards the mouse while the mouse button is clicked and then of course stay pointing in that direction after the mouse is lifted. void Square::handle_input() { //If a key was pressed if( event.type == SDL_KEYDOWN ) { //Adjust the velocity switch( event.key.keysym.sym ) { case SDLK_UP: upUp = false; yVel = -1; break; case SDLK_DOWN: downUp = false; yVel = 1; break; case SDLK_LEFT: leftUp = false; xVel = -1; break; case SDLK_RIGHT: rightUp = false; xVel = 1; break; case SDLK_w: wUp = false; sAng = 1; break; case SDLK_s: sUp = false; sAng = -1; break; } } //If a key was released else if( event.type == SDL_KEYUP ) { //Adjust the velocity switch( event.key.keysym.sym ) { case SDLK_UP: upUp = true; yVel = 0; break; case SDLK_DOWN: downUp = true; yVel = 0; break; case SDLK_LEFT: leftUp = true; xVel = 0; break; case SDLK_RIGHT: rightUp = true; xVel = 0; break; case SDLK_w: wUp = true; sAng = 0; break; case SDLK_s: sUp = true; sAng = 0; break; } } //If a mouse button was pressed if( event.type == SDL_MOUSEBUTTONDOWN ) { switch ( event.type ) { case SDL_MOUSEBUTTONDOWN: mouseUp = false; mousex == event.button.x; mousey == event.button.y; break; case SDL_MOUSEBUTTONUP: mouseUp = true; break; } } } And then this is called at the end of my Object::Move call which also handles x and y translation if (!mouseUp) { xVect = mousex - x; yVect = mousey - y; radAng = atan2 ( mousey - y, mousex - x ); sAng = radAng * 180 / 3.1415926l; } Right now when I click the object turns and faces down to the bottom left but then no longer changes direction. I'd really appreciate any help I could get here. I'm guessing there might be an issue here with state versus polled events but from all the tutorials that I've been through I was pretty sure I had fixed that. I've just hit a wall and I need some advice!

  • What's wrong with this code to un-camel-case a string?

    - by omair iqbal
    Here is my attempt to solve the About.com Delphi challenge to un-camel-case a string. unit challenge1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls; type check = 65..90; TForm1 = class(TForm) Edit1: TEdit; Button1: TButton; procedure Button1Click(Sender: TObject); private { Private declarations } public { Public declarations } end; var Form1: TForm1; var s1,s2 :string; int : integer; implementation {$R *.dfm} procedure TForm1.Button1Click(Sender: TObject); var i: Integer; checks : set of check; begin s1 := edit1.Text; for i := 1 to 20 do begin int :=ord(s1[i]) ; if int in checks then insert(' ',s1,i-1); end; showmessage(s1); end; end. check is a set that contains capital letters so basically whenever a capital letter is encountered the insert function adds space before its encountered (inside the s1 string), but my code does nothing. ShowMessage just shows text as it was entered in Edit1. What have I done wrong?

  • Grails Navigation with Dynamic Values

    - by TripWired
    I'm using the grails navigation plugin and one of the things i want to do is have the menu item have a dynamic number in it for example static navigation = [ group:'tabs', order:7, title:'Mail', action:'index', subItems: [ [action:'pending', order:1, title:"Pending"], [action:'active', order:10, title:'Active'], [action:'completed', order:11, title:'Completed'] ] ] So i want to figure out a way to make the title Mail(3) or Mail(2) based on the amount of messages a user has. I know this will have to be set in the method or by a service of some sort i'm just not sure how to get it to update.

  • Cant get description rss tag data with javascript

    - by AdamB
    I'm currently making a widget to take and display items from a feed. I have this working for the most part, but for some reason the data within the tag within the item comes back as empty, but I get the data in the and tags no problem. feed is and xmlhttp.responseXML object. var items = feed.getElementsByTagName("item"); for (var i=0; i<10; i++){ container = document.getElementById('list'); new_element = document.createElement('li'); title = items[i].getElementsByTagName("title")[0].firstChild.nodeValue; link = items[i].getElementsByTagName("link")[0].firstChild.nodeValue; alert(items[i].getElementsByTagName("description")[0].firstChild.nodeValue); new_element.innerHTML = "<a href=\""+link+"\">"+title+"</a> "; container.insertBefore(new_element, container.firstChild); } I have no idea why it wouldn't be working for the tag and would be for the other tags. Here is an example of the rss feed its trying to parse: <rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/"> <channel> <title>A title</title> <link>http://linksomehwere</link> <description>The title of the feed</description> <language>en-us</language> <item> <pubDate>Fri, 10 Jul 2009 11:34:49 -0500</pubDate> <title>Awesome Title</title> <link>http://link/to/thing</link> <guid>http://link/to/thing</guid> <description> <![CDATA[ <p>some html crap</p> blah blah balh ]]> </description> </item> </channel> </rss>

  • Sort/Group XML data with PHP?

    - by Volmar
    I'm trying to make a page using data from the discogs.com (XML)-API. i've been parsing it with simpleXML and it's working pretty well but there is some things i'm not sure how to do. Here is part of the XML: <releases> <release id="1468764" status="Accepted" type="Main"> <title>Versions</title> <format>12", EP</format> <label>Not On Label</label> <year>1999</year> </release> <release id="72246" status="Accepted" type="Main"> <title>The M.O.F Blend</title> <format>LP</format> <label>Blenda Records</label> <year>2002</year> </release> <release id="890064" status="Accepted" type="Main"> <title>The M.O.F Blend</title> <format>CD</format> <label>Blenda Records</label> <year>2002</year> </release> <release id="1563561" status="Accepted" type="TrackAppearance"> <title>Ännu En Gång Vol. 3</title> <trackinfo>Backtrack</trackinfo> <format>Cass, Comp, Mix</format> <label>Hemmalaget</label> <year>2001</year> </release> </releases> What i want to achieve is something similair to how discogs presents the releases: http://www.discogs.com/artist/Mics+Of+Fury where diferent versions of the same release are sorted together. (see. The M.O.F Blend in my link) This is done on discogs with having a master release that features the other releases. unfortunately this information isn't present in the API data, so i want to do the same thing by grouping the <release>-nodes with the same <title>-tags, or add a flag to the <releases> that don't have a unique <title>? any good ideas on the best way of doing this? i also like to know if it's possible to count the <release>-nodes (child of releases) that have the same type-attribute? like in this example count the releases with the type "Main"? maybe it's better to do this things with XMLReader or XPath?

  • Providing lat/long AND title in iOS Maps URL seems to cause zoom level to be ignored

    - by Ian Howson
    I'm writing an iOS app that shows a location in Maps upon a user action. I'd like to drop a pin with a description and zoom in to show map detail. If I invoke Maps with the url http://maps.google.com/maps?q=-33.895851,151.18483+(Some+Description)&z=19 I get a pin with 'Some Description', but the zoom level is ignored. This does work on the Google Maps website. If I use http://maps.google.com/maps?q=-33.895851,151.18483&z=19 the zoom works, but I get no pin. I've tried a few combinations of ?q=, ?ll= and ?sll=, but so far, nothing will change zoom and show a description. Any clues? Just so we're really clear, here are some screenshots. I want this to work on a real device (i.e. with iOS Maps). The simulator uses Google Maps through Safari. Here's what I see with URL 1 ([[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://maps.google.com/maps?q=-33.895851,151.18483+(Some+Description)&z=19"]];) This is URL 2 ([[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://maps.google.com/maps?q=-33.895851,151.18483&z=19"]];): This is relikd's suggestion ([[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://maps.google.com/maps?z=19&q=-33.895851,151.18483+(Some+Description)"]];): I want the image I see in screenshot 2, but with a pin and a description.

  • What is the purpose of the s==NULL case for mbrtowc?

    - by R..
    mbrtowc is specified to handle a NULL pointer for the s (multibyte character pointer) argument as follows: If s is a null pointer, the mbrtowc() function shall be equivalent to the call: mbrtowc(NULL, "", 1, ps) In this case, the values of the arguments pwc and n are ignored. As far as I can tell, this usage is largely useless. If ps is not storing any partially-converted character, the call will simply return 0 with no side effects. If ps is storing a partially-converted character, then since '\0' is not valid as the next byte in a multibyte sequence ('\0' can only be a string terminator), the call will return (size_t)-1 with errno==EILSEQ. and leave ps in an undefined state. The intended usage seems to have been to reset the state variable, particularly when NULL is passed for ps and the internal state has been used, analogous to mbtowc's behavior with stateful encodings, but this is not specified anywhere as far as I can tell, and it conflicts with the semantics for mbrtowc's storage of partially-converted characters (if mbrtowc were to reset state when encountering a 0 byte after a potentially-valid initial subsequence, it would be unable to detect this dangerous invalid sequence). If mbrtowc were specified to reset the state variable only when s is NULL, but not when it points to a 0 byte, a desirable state-reset behavior would be possible, but such behavior would violate the standard as written. Is this a defect in the standard? As far as I can tell, there is absolutely no way to reset the internal state (used when ps is NULL) once an illegal sequence has been encountered, and thus no correct program can use mbrtowc with ps==NULL.

  • Scanner error that I can't figure out: NoSuchElementException

    - by iaacp
    It's crashing on the third line inside the do-while loop, and doesn't wait for my input: input = kb.nextInt(); Stack trace: Exception in thread "main" java.util.NoSuchElementException at java.util.Scanner.throwFor(Unknown Source) at java.util.Scanner.next(Unknown Source) at java.util.Scanner.nextInt(Unknown Source) at java.util.Scanner.nextInt(Unknown Source) at main.MainDriver.main(MainDriver.java:50) Relevant code: do { displayFullMenu(); System.out.print("Selection: "); input = kb.nextInt(); switch (input) { //Create new survey case 1: currentSurvey = new Survey(); break; //Display current survey case 2: currentSurvey.display(); break; //Save current survey case 3: saveSurvey(currentSurvey); break; //Load a survey case 4: currentSurvey = loadSurvey(); break; //Modify a survey case 5: currentSurvey.modify(); break; /*******************Test Functions*******************/ //Create new test case 6: currentSurvey = new Test(); break; //Display current test case 7: currentSurvey.display(); break; //Save current test case 8: saveSurvey(currentSurvey); break; //Load a test case 9: currentSurvey = loadTest(); break; //Modify a test case 10: currentSurvey.modify(); default: System.out.println("Invalid choice.

It saves the file correctly, then goes back to the top of the loop, and crashes at the previously mentioned line. I want it to ask for more input. What gives?

  • Overlapping template partial specialization when wanting an "override" case: how to avoid the error?

    - by user173342
    I'm dealing with a pretty simple template struct that has an enum value set by whether its 2 template parameters are the same type or not. template<typename T, typename U> struct is_same { enum { value = 0 }; }; template<typename T> struct is_same<T, T> { enum { value = 1 }; }; This is part of a library (Eigen), so I can't alter this design without breaking it. When value == 0, a static assert aborts compilation. So I have a special numerical templated class SpecialCase that can do ops with different specializations of itself. So I set up an override like this: template<typename T> struct SpecialCase { ... }; template<typename LT, typename RT> struct is_same<SpecialCase<LT>, SpecialCase<RT>> { enum { value = 1 }; }; However, this throws the error: more than one partial specialization matches the template argument list Now, I understand why. It's the case where LT == RT, which steps on the toes of is_same<T, T>. What I don't know is how to keep my SpecialCase override and get rid of the error. Is there a trick to get around this? edit: To clarify, I need all cases where LT != RT to also be considered the same (have value 1). Not just LT == RT.

  • What is the best way to declare sorted association in grails domain classes ?

    - by fabien7474
    It seems that there are two different ways of declaring sorted associations in Grails : Method 1 (see here) using default sort order class Book { String title } class Author { static hasMany = [books : Book] static mapping = { books sort: "title"} } Method 2 (see here) using SortedSet class Book implements Comparable { String title int compareTo(obj) { title <=> obj.title } } class Author { SortedSet books static hasMany = [books : Book] } I am not sure which one to use and what is the difference (if any), pros and cons between using one against the other. I would appreciate any clarification. Thank you

  • Good case for a Null Object Pattern? (Provide some service with a mailservice)

    - by fireeyedboy
    For a website I'm working on, I made an Media Service object that I use in the front end, as well as in the backend (CMS). This Media Service object manipulates media in a local repository (DB); it provides the ability to upload/embed video's and upload images. In other words, website visitors are able to do this in the front end, but administrators of the site are also able to do this in the backend. I'ld like this service to mail the administrators when a visitor has uploaded/embedded a new medium in the frontend, but refrain from mailing them when they upload/embed a medium themself in the backend. So I started wondering whether this is a good case for passing a null object, that mimicks the mail funcionality, to the Media Service in the backend. I thought this might come in handy when they decide the backend needs to have implemented mail functionality as well. In simplified terms I'ld like to do something like this: Frontend: $mediaService = new MediaService( new MediaRepository(), new StandardMailService() ); Backend: $mediaService = new MediaService( new MediaRepository(), new NullMailService() ); How do you feel about this? Does this make sense? Or am I setting myself up for problems down the road?

  • Why don't languages use explicit fall-through on switch statements?

    - by zzzzBov
    I was reading Why do we have to use break in switch?, and it led me to wonder why implicit fall-through is allowed in some languages (such as PHP and JavaScript), while there is no support (AFAIK) for explicit fall-through. It's not like a new keyword would need to be created, as continue would be perfectly appropriate, and would solve any issues of ambiguity for whether the author meant for a case to fall through. The currently supported form is: switch (s) { case 1: ... break; case 2: ... //ambiguous, was break forgotten? case 3: ... break; default: ... break; } Whereas it would make sense for it to be written as: switch (s) { case 1: ... break; case 2: ... continue; //unambiguous, the author was explicit case 3: ... break; default: ... break; } For purposes of this question lets ignore the issue of whether or not fall-throughs are a good coding style. Are there any languages that exist that allow fall-through and have made it explicit? Are there any historical reasons that switch allows for implicit fall-through instead of explicit?

  • stored procedure issue, has to do with my where clause and if statement

    - by MyHeadHurts
    right now my stored procedure is returning 2 different result sets one for @booked and the other for @booked1 if you look closely my query is doing the same thing for each @booked and @booked but one is for a user selected year and the other for the current year. I don't want two different result sets, i want to join the selected year and the current year side by side by SDESCR(which is a column that they have in common) another hurdle i am facing is i am use @mode to decide whether the user wants netsales, sales... so on. I know i need sometype of join but, it isnt working because i have a where statement that says where dyyyy= @yeartoget which won't allow the current year data to work ALTER PROCEDURE [dbo].[test1] @mode varchar(20), @YearToGet int AS SET NOCOUNT ON Declare @Booked Int Set @Booked = CONVERT(int,DateAdd(year, @YearToGet - Year(getdate() + 1), DateAdd(day, DateDiff(day, 1, getdate()), 1) ) ) Declare @Booked1 Int Set @Booked1 = CONVERT(int,DateAdd(year, (year( getdate() )) - Year(getdate() + 1), DateAdd(day, DateDiff(day, 1, getdate()), 1) ) ) If @mode = 'Sales' Select Division, SDESCR, DYYYY, Sum(Case When Booked <= @Booked Then NetAmount End) ASofNetSales, SUM(NetAmount) AS YENetSales, Sum(Case When Booked <= @Booked Then PARTY End) AS ASofPAX, SUM(PARTY) AS YEPAX From dbo.B101BookingsDetails Where DYYYY = @YearToGet Group By SDESCR, DYYYY, Division Order By Division, SDESCR, DYYYY else if @mode = 'netsales' Select Division, SDESCR, DYYYY, Sum(Case When Booked <= @Booked Then NetAmount End) ASofNetSales, SUM(NetAmount) AS YENetSales, Sum(Case When Booked <= @Booked Then PARTY End) AS ASofPAX, SUM(PARTY) AS YEPAX From dbo.B101BookingsDetails Where DYYYY = @YearToGet Group By SDESCR, DYYYY, Division Order By Division, SDESCR, DYYYY If @mode = 'Sales' Select Division, SDESCR, DYYYY, Sum(Case When Booked <= @Booked1 Then NetAmount End) currentNetSales, Sum(Case When Booked <= @Booked1 Then PARTY End) AS currentPAX From dbo.B101BookingsDetails Where DYYYY = (year( getdate() )) Group By SDESCR, DYYYY, Division Order By Division, SDESCR, DYYYY else if @mode = 'netsales' Select Division, SDESCR, DYYYY, Sum(Case When Booked <= @Booked1 Then NetAmount End) currentNetSales, Sum(Case When Booked <= @Booked1 Then PARTY End) AS currentPAX From dbo.B101BookingsDetails Where DYYYY = (year( getdate() )) Group By SDESCR, DYYYY, Division Order By Division, SDESCR, DYYYY Else if @mode = 'Inssales' Select Division, SDESCR, DYYYY, Sum(Case When Booked <= @Booked1 Then InsAmount End) currentInsSales, Sum(Case When Booked <= @Booked1 Then PARTY End) AS currentPAX From dbo.B101BookingsDetails Where DYYYY = (year( getdate() )) Group By SDESCR, DYYYY, Division Order By Division, SDESCR, DYYYY

  • Using .Net, how can I determine if a type is a Numeric ValueType?

    - by Nescio
    Title says it all... But here's an example: Dim desiredType as Type if IsNumeric(desiredType) then ... EDIT: I only know the Type, not the Value as a string. Ok, so unfortunately I have to cycle through the TypeCode. But this is a nice way to do it: if ((desiredType.IsArray)) return 0; switch (Type.GetTypeCode(desiredType)) { case 3: case 6: case 7: case 9: case 11: case 13: case 14: case 15: return 1; } ;return 0;
