  • ext4 hogs lot of unkown space compared to ext3

    - by rejith
    Ext4 FS has claimed 3% of partition space. Where has this gone and can I get it reclaimed? I have tried disabling Journals for the ext4 partition. Even this is not helping. Any other tricks I can try to get the space reclaimed other than reverting back to ext3? $ lsb_release -cr Release: 12.04 Codename: precise df -hP |grep media /dev/sda3 21G 430M 20G 3% /media/MAIL /dev/sda2 148G 188M 148G 1% /media/DATA => if I move this to ext4 its claiming 2.4G /dev/sda3 on /media/MAIL type ext4 (rw,nosuid,nodev,uhelper=udisks) /dev/sda2 on /media/DATA type ext3 (rw,nosuid,nodev,uhelper=udisks) $ sudo tune2fs -l /dev/sda3 |grep 'Reserved block count' Reserved block count: 0 $ sudo tune2fs -l /dev/sda2 |grep 'Reserved block count' Reserved block count: 0 NO hidden files or directories $ sudo du -ah *;pwd 16K lost+found /media/MAIL

  • Must a Language that Implements Monads be Statically Typed?

    - by Morgan Cheng
    I am learning functional programming style. From this link http://channel9.msdn.com/shows/Going+Deep/Brian-Beckman-Dont-fear-the-Monads/, Brian Beckman gave a brilliant introduction about Monad. He mentioned that Monad is about composition of functions so as to address complexity. A Monad includes a unit function that transfers type T to an amplified type M(T); and a Bind function that, given function from T to M(U), transforms type M(T) to another type M(U). (U can be T, but is not necessarily). In my understanding, the language implementing monad should be type-checked statically. Otherwise, type errors cannot be found during compilation and "Complexity" is not controlled. Is my understanding correct?

  • Tool to detect use/abuse of String.Concat (where StringBuilder should be used)

    - by Mark Rushakoff
    It's common knowledge that you shouldn't use a StringBuilder in place of a small number of concatenations: string s = "Hello"; if (greetingWorld) { s += " World"; } s += "!"; However, in loops of a significant size, StringBuilder is the obvious choice: string s = ""; foreach (var i in Enumerable.Range(1,5000)) { s += i.ToString(); } Console.WriteLine(s); Is there a tool that I can run on either raw C# source or a compiled assembly to identify where in the source code that String.Concat is being called? (If you're not familiar, s += "foo" is mapped to String.Concat in the IL output.) Obviously, I can't realistically search through an entire project and evaluate every += to identify whether the lvalue is a string. Ideally, it would only point out calls inside a for/foreach loop, but I would even put up with all the false positives of noting every String.Concat. Also, I'm aware that there are some refactoring tools that will automatically refactor my code to use StringBuilder, but I am only interested in identifying the Concat usage at this point. I routinely run Gendarme and FxCop on my code, and neither of those tools identify what I've described.

  • android playback suddenly stopping...

    - by user306517
    I have an app that is streaming audio content and sometimes it just stops all of the suddent. the logcat windows shows -- AudioHardware pcm playback is going to standby and that's it. I saw on another thread (pun intended) that someone was saying it was because he was using too many threads. Could that really be causing this? Could i give the audio thread higher priority? Anyway to prevent the audio hardware pcm from going to standby?

  • On Render Callback For G+ Button

    - by Michael Robinson
    How might I go about performing an action only when a G+ button has finished rendering? Facebook allows one to do this using the following: FB.XFBML.parse(document, function() { alert('rendering done'); }); I've perused Google's documentation, but didn't see anything helpful. Currently my workaround is to monitor the G+ element until certain elements have been added, then perform my action: (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; po.onload = function() { var awaitRender = function(element) { if (element.firstChild && element.firstChild.firstChild && element.firstChild.firstChild.tagName.toUpperCase() === 'IFRAME') { alert('rendered!'); } else { window.setTimeout(function() { awaitRender(element) }, 100); } }; var buttons = document.getElementsByClassName('googleplus-button'); for(var i = 0; i < buttons.length; i++) { awaitRender(buttons[i]); } } var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })(); I'd like to know please, if there is either: A correct way one should do this for G+ buttons A better implementation that what I've hacked together above

  • Discover NullPointerException bugs using FindBug

    - by alex2k8
    When I run FindBug on this code, it reports NO issues. boolean _closed = false; public void m1(@Nullable String text) { if(_closed) return; System.out.println(text.toLowerCase()); } While here it finds issue as expected: public void m1(@Nullable String text) { System.out.println(text.toLowerCase()); // FireBug: text must be nonnull but is marked as nullable } Why does it fail in first case?

    I am a PHP web programmer who is trying to learn C#. I would like to know why C# requires me to specify the data type when creating a variable. Class classInstance = new Class(); Why do we need to know the data type before a class instance?

  • Core Data produces Analyzer warnings

    - by RickiG
    Hi I am doing the final touch ups on an app and I am getting rid of every compiler/analyzer warning. I have a bunch of Class methods that wrap my apps access to Core Data entities. This is "provoking" the analyzer. + (CDProductEntity*) newProductEntity { return (CDProductEntity*)[NSEntityDescription insertNewObjectForEntityForName:@"CDProductEntity" inManagedObjectContext:[self context]]; } Which results in an Analyzer warning: Object with +0 retain counts returned to caller where a +1 (owning) retain count is expected In the method that calls the above Class Method I have this: CDProductEntity *newEntity = [self newProductEntity]; Which results in an Analyzer warning: Method returns an Objective-C object with a +1 retain count (owning reference) Explicitly releasing or autoreleasing a Core Data entity is usually very very bad, but is that what it is asking me to do here? First it tells me it has a +0 retain count and that is bad, then it tells me it has a +1 which is also bad. What can I do to ensure that I am either dealing with a Analyzer hiccup or that I release correctly? Thanks in advance

  • Gimpel's PC-lint and Flexelint; Anyone used them?

    - by samoz
    So I've read a few magazine articles and the website for Gimpel's PC-lint and Flexelint C/C++ compiler. It's really expensive (at least for me), but it seems like it might have some merit to warrant the cost. So I'm wondering if anyone else has used/bought them and can provide their opinions?

  • How to import music into Android library

    - by android_dev
    Hello, I would like to know how can I import songs from a web service into Android library without having to download the file into sdcard. I have all the data from the web service but I do not know how to integrate the tracks into Android database. My idea is not to have to download the files, but playing them on streaming using the music player. Do I need to download the tracks to the sd card and then Android does all the stuff? Thanks in advance

  • Typed metaprogramming languages

    - by Jacques Carette
    I want to do some metaprogramming in a statically typed language, where both my programs and my meta-programs will be typed. I mean this in a strong sense: if my program generator compiles, I want the type system to be strong enough that only type-correct programs can be generated. As far as I know, only metaocaml can do this. (No, neither Template Haskell nor C++ templates fit the bill -- see this paper).

  • Playing BG Music Across Activities in Android

    - by scarface
    Hello! First time to ask a question here at stackoverflow. Exciting! Haha. We're developing an Android game and we play some background music for our intro (we have an Intro Activity) but we want it to continue playing to the next Activity, and perhaps be able to stop or play the music again from anywhere within the application. What we're doing at the moment is play the bgm using MediaPlayer at our Intro Activity. However, we stop the music as soon as the user leaves that Activity. Do we have to use something like Services for this? Or is MediaPlayer/SoundPool enough? If anyone knows the answer, we'd gladly appreciate your sharing it with us. Thanks!

  • Why do we have reinterpret_cast in C++ when two chained static_cast can do it's job?

    - by Nawaz
    Say I want to cast A* to char* and vice-versa, we have two choices (I mean, many of us think we've two choices, because both seems to work! Hence the confusion!): struct A { int age; char name[128]; }; A a; char *buffer = static_cast<char*>(static_cast<void*>(&a)); //choice 1 char *buffer = reinterpret_cast<char*>(&a); //choice 2 Both work fine. //convert back A *pA = static_cast<A*>(static_cast<void*>(buffer)); //choice 1 A *pA = reinterpret_cast<A*>(buffer); //choice 2 Even this works fine! So why do we have reinterpret_cast in C++ when two chained static_cast can do it's job? Some of you might think this topic is a duplicate of the previous topics such as listed at the bottom of this post, but it's not. Those topics discuss only theoretically, but none of them gives even a single example demonstrating why reintepret_cast is really needed, and two static_cast would surely fail. I agree, one static_cast would fail. But how about two? If the syntax of two chained static_cast looks cumbersome, then we can write a function template to make it more programmer-friendly: template<class To, class From> To any_cast(From v) { return static_cast<To>(static_cast<void*>(v)); } And then we can use this, as: char *buffer = any_cast<char*>(&a); //choice 1 char *buffer = reinterpret_cast<char*>(&a); //choice 2 //convert back A *pA = any_cast<A*>(buffer); //choice 1 A *pA = reinterpret_cast<A*>(buffer); //choice 2 Also, see this situation where any_cast can be useful: Proper casting for fstream read and write member functions. So my question basically is, Why do we have reinterpret_cast in C++? Please show me even a single example where two chained static_cast would surely fail to do the same job? Which cast to use; static_cast or reinterpret_cast? Cast from Void* to TYPE* : static_cast or reinterpret_cast

  • CDN for Images in ASP.NET

    - by Chris
    I am in the process of moving all of the images in my web application over to a CDN but I want to easily be able to switch the CDN on or off without having to hard code the path to the images. My first thought was to add an HttpHandler for image extensions that depending whether a variable in the web.config (something like ) will serve the image from the server or from the CDN. But after giving this a little though I think I've essentially ruled this out as it will cause ASP.NET to handle the request for every single image, thus adding overhead, and it might actually completely mitigate the benefits of using a CDN. An alternative approach is, since all of my pages inherit from a base page class, I could create a function in the base class that determines what path to serve the files from based off the web.config variable. I would then do something like this in the markup: <img src='<%= GetImagePath()/image.png' /> I think this is probably what I'll have to end up doing, but it seems a little clunky to me. I also envision problems with the old .NET error of not being able to modify the control collection because of the "<%=" though the "<%#" solution will probably work. Any thoughts or ideas on how to implement this?

  • Boost Test dynamically or statically linked?

    - by Halt
    We use Boost statically linked with our app but now I wan't to use Boost Test with an external test runner and that requires the tests themselves to link dynamically with Boost.Test through the use of the required BOOST_TEST_DYN_LINK define. Is this going to be a problem or is the way Boost Test links completely unrelated to the way the other Boost libraries are linked? Thx.

  • An old flaw in X Window System. How does it work?

    - by Legend
    I was going through an article today when it mentioned the following: "We've found many errors over the years. One of the absolute best was the following in the X Window System: if(getuid() != 0 && geteuid == 0) { ErrorF("Only root"); exit(1); } It allowed any local user to get root access. (The tautological check geteuid == 0 was intended to be geteuid() == 0. In its current form, it compress the address of geteuid to 0; given that the function exists, its address is never 0)." The article explained what was wrong with the code but I would like to know what it means to say that "It allowed any local user to get root access". I am not an expert in C but can someone give me an exact context in which this exploit would work? Specifically, what I mean is, lets say I am the local user, how would I get root access if we assume this code to be present somewhere?

  • Statically checking a Java app for link errors

    - by monorailkitty
    I have a scenario where I have code written against version 1 of a library but I want to ship version 2 of the library instead. The code has shipped and is therefore not changeable. I'm concerned that it might try to access classes or members of the library that existed in v1 but have been removed in v2. I figured it would be possible to write a tool to do a simple check to see if the code will link against the newer version of the library. I appreciate that the code may still be very broken even if the code links. I am thinking about this from the other side - if the code won't link then I can be sure there is a problem. As far as I can see, I need to run through the bytecode checking for references, method calls and field accesses to library classes then use reflection to check whether the class/member exists. I have three-fold question: (1) Does such a tool exist already? (2) I have a niggling feeling it is much more complicated that I imagine and that I have missed something major - is that the case? (3) Do you know of a handy library that would allow me to inspect the bytecode such that I can find the method calls, references etc.? Thanks!

  • Is the scope of what Xcode's "Build and Analyze" will catch as a leak supposed to be this limited?

    - by Ranking Stackingblocks
    It doesn't care about this: NSString* leaker() { return [[NSString alloc] init]; } I thought it would have been smart enough to check if any code paths could call that function without releasing its return value (I wouldn't normally code this way, I'm just testing the analyzer). It reports this as a leak: NSString* leaker() { NSString* s = [[NSString alloc] init]; [s retain]; return s; } but NOT this: NSString* leaker() { NSString* s = [[NSString alloc] init]; // [s retain]; return s; } which seems particularly weak to me. Does it only analyze within the local scope? If the tool can't pick up on things like this, how can I expect it to pick up on actual mistakes that I might make?

  • Re-usable Obj-C classes with custom values: The right way

    - by Prairiedogg
    I'm trying to reuse a group of Obj-C clases between iPhone applications. The values that differ from app to app have been isolated and I'm trying to figure out the best way to apply these custom values to the classes on an app-to-app basis. Should I hold them in code? // I might have 10 customizable values for each class, that's a long signature! CarController *controller = [[CarController alloc] initWithFontName:@"Vroom" engine:@"Diesel" color:@"Red" number:11]; Should I store them in a big settings.plist? // Wasteful! I sometimes only use 2-3 of 50 settings! AllMyAppSettings *settings = [[AllMyAppSettings alloc] initFromDisk:@"settings.plist"]; MyCustomController *controller = [[MyCustomController alloc] initWithSettings:settings]; [settings release]; Should I have little, optional n_settings.plists for each class? // Sometimes I customize CarControllerSettings *carSettings = [[CarControllerSettings alloc] initFromDisk:@"car_settings.plist"]; CarController *controller = [[CarController alloc] initWithSettings:carSettings]; [carSettings release]; // Sometimes I don't, and CarController falls back to internally stored, reasonable defaults. CarController *controller = [[CarController alloc] initWithSettings:nil]; Or is there an OO solution that I'm not thinking of at all that would be better?

  • Permissions scheme not working

    - by ReaZem
    I am currently building a home server and I am trying to give minimal permissions to every service. I am new to permissions management and this is an awesome learning experience for me :). drwxr----- 7 reazem enter-home 4096 Sep 9 21:43 reazem drwxrws--- 3 reazem minidlna 4096 Sep 9 21:36 media reazem is my home folder and media is my media folder, it is situated directly inside my home. The minidlna user is part of the following groups : minidlna, enter-home. I get the following error: Media directory not accessible! [/home/reazem/media] I was hoping that because the minidlna user is part of the enter-home group, it could get inside the home folder, and then inside the media folder because it is in the minidlna group. Where is my mistake? Edit: I found out that chmod g+x /home/reazem solved the problem, but why? Why would you need the execute permission to get inside another directory? Thank you!
