  • When would you put a semicolon after a method closing brace?

    - by froadie
    I've been programming in Java for a while, and I've just come across this syntax for the first time: public Object getSomething(){return something;}; What's interesting me is the final semicolon. It doesn't seem to be causing a compiler error, and as far as I know isn't generating runtime errors, so it seems to be valid syntax. When would I use this syntax? Or is it just something that is allowed but generally not used?

  • Why my new GTX 660m's clock drops drastically after running few seconds

    - by trVoldemort
    I bought a Lenovo Y580 laptop few days ago, this model is equipped with GTX 660m graphics card. However, the game performance is unbelievably poor since it out from the box. I realized there is something wrong with this graphics card. I downloaded GPU-z, and did a simple test. And I was shocked by the fact that my GTX 660m graphics card is running at 135.0mhz core clock. (It should be 835mhz at least!) Even the integrated graphics card "Intel HD graphics 4000" can run at 650mhz. Further examining showed that in the first few seconds GTX 660m was actually running at 835mhz, however the core temperature quickly reached 90+°C and the clock (maybe) automatically drop to 135.0mhz. This is very strange. Anyone has any idea what's going on here?

  • Multiprogramming in Django, writing to the Database

    - by Marcus Whybrow
    Introduction I have the following code which checks to see if a similar model exists in the database, and if it does not it creates the new model: class BookProfile(): # ... def save(self, *args, **kwargs): uniqueConstraint = {'book_instance': self.book_instance, 'collection': self.collection} # Test for other objects with identical values profiles = BookProfile.objects.filter(Q(**uniqueConstraint) & ~Q(pk=self.pk)) # If none are found create the object, else fail. if len(profiles) == 0: super(BookProfile, self).save(*args, **kwargs) else: raise ValidationError('A Book Profile for that book instance in that collection already exists') I first build my constraints, then search for a model with those values which I am enforcing must be unique Q(**uniqueConstraint). In addition I ensure that if the save method is updating and not inserting, that we do not find this object when looking for other similar objects ~Q(pk=self.pk). I should mention that I ham implementing soft delete (with a modified objects manager which only shows non-deleted objects) which is why I must check for myself rather then relying on unique_together errors. Problem Right thats the introduction out of the way. My problem is that when multiple identical objects are saved in quick (or as near as simultaneous) succession, sometimes both get added even though the first being added should prevent the second. I have tested the code in the shell and it succeeds every time I run it. Thus my assumption is if say we have two objects being added Object A and Object B. Object A runs its check upon save() being called. Then the process saving Object B gets some time on the processor. Object B runs that same test, but Object A has not yet been added so Object B is added to the database. Then Object A regains control of the processor, and has allready run its test, even though identical Object B is in the database, it adds it regardless. My Thoughts The reason I fear multiprogramming could be involved is that each Object A and Object is being added through an API save view, so a request to the view is made for each save, thus not a single request with multiple sequential saves on objects. It might be the case that Apache is creating a process for each request, and thus causing the problems I think I am seeing. As you would expect, the problem only occurs sometimes, which is characteristic of multiprogramming or multiprocessing errors. If this is the case, is there a way to make the test and set parts of the save() method a critical section, so that a process switch cannot happen between the test and the set?

  • EC2 Apache Server not reflecting changes to PHP files

    - by Josef van Niekerk
    We're running a Laravel application on an Amazon EC2 server with Apache installed. I've noticed on multiple occasions, that the server doesn't respond to changes in PHP files, even after restarting Apache. For example, if I edit a file that I'm accessing through a URL, and I break the syntax, I don't even get a PHP exception thrown. This is really strange, and has been sticking its head out more frequently these days. Is it possible Apache is caching the PHP files somewhere? Opcode caching perhaps?

  • Is there a jQuery plugin for error messages at top like Twitter?

    - by sami
    I'm looking for a jquery plugin that would create an errors div like what twitter has. The div gets added by the plugin, it stays hidden while it doesn't have content, then when a message gets added to it, it appears at the top (with either a close button option or automatic disappear after an x number of seconds). It's not too difficult to write, but there would be no reason to write it if it's already been done before. Anyone knows of a plugin like that?

  • CentOS/Apache killing connections

    - by fin1te
    Getting a really strange error. Basically, whenever I browse to my server (http://[ip_address] or http://[hostname]), it doesn't load, and my active SSH connection drops out. I installed CentOS 5.5, and then httpd and PHP 5.3. No other applications where installed, so I can't imagine it's something else causing it. I also reinstalled CentOS 5.5 again, completely fresh, the only thing I did to it was yum install httpd, and it still caused this issue. I've changed nothing in the config or anything else. Driving me mad, has anyone heard of this? It's really frustrating since everytime I attempt to debug this issue, I get kicked off SSH and have to log back in. Theres nothing in the Apache error logs, and nothing in the access log recording my attempt. Also, the result from uname - Linux [hostname] 2.6.35.4-rscloud #8 SMP Mon Sep 20 15:54:33 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux Thank you

  • Are any of these SQL Queries open to SQL injection attacks?

    - by Phil
    I have re-written my code after great help from some friendly stack overflow members (big thanks to Martin B and Kev Chadders especially). I would now like to check if my code is still open to SQL Injections after this work. I believe the code is now working as it should, but any blinding errors that you see i'd love to hear about too. My code is now looking like: -code removed-

  • is there difference between debug and release reference path while compiling?

    - by Nair
    I am building a SL3 + RIA application in VS2008. When compiled the application in debug mode it compiles fine with out any error, but when I compile the same application with out any code change in release mode I get an error 'The type of namespace name 'BusyIndicator' does not exist in the namespace 'System.Windows.Controls' (are you missing an assembly reference). All the errors are coming from the generated code name.g.cs Just curious anyone run into this problem.

  • How to handle unknown initializer functions in lua?

    - by oofoe
    I want to load data written in a variant of lua (eyeonScript). However, the data is peppered with references to initialization functions that are not in plain lua: Redden = BrightnessContrast { Inputs = { Red = Input { Value = 0, }, }, } Standard lua gives "attempt to call a nil value" or "unexpected symbol" errors. Is there any way to catch these and pass it to some sort of generic initializer? I want to wind up with a nested table data structure. Thanks!

  • How to manually create a DBRef using pymongo?

    - by Soviut
    I want to create a DBRef manually so that I can add an additional field to it. However, when I try to pass the following: {'$ref': 'projects', '$id': '1029412409721', 'project_name': 'My Project'} Pymongo raises an error: pymongo.errors.InvalidName: key '$id' must not start with '$' It would seem that pymongo reserve the $ for the special key, leading me to wonder if it is even possible to do what I'm trying to do?

  • Windows 7 - problems launching default application

    - by Chris W
    Just built up a new W7 PC. I've noticed some strange issues with launching default applications. I've got Visual Studio & SQL Server Management Studio set run as administrator when launched. If i double click a .sql file SSMS opens ok but the file itself does not get loaded. If I do the same with a .sln then I get nothing at all from Visual Studio. For the latter I presume the UAC prompt is hidden somewhere waiting for me to say it's ok to launch the app but i've no idea what's happening with SSMS. Is this a W7 bug or are there some settings somewhere that I can tweak to improve this behaviour?

  • Do you have examples of un-helpful/Obscure error messages

    - by Wiretap
    Yesterday I got this error The processing instruction target matching "[xX][mM][lL]" is not allowed when I investigated, it was caused by whitespace at the very start of my XML document. Not difficult to solve, but I was struck with how unhelpful that particular error message was to identifying the actual problem. So what other examples of obscure errors do people have, and are you willing to admit to some of your own making.

  • `var = something rescue nil` behaviour

    - by JP
    In ruby you can throw a rescue at the end of an assignment to catch any errors that might come up. I have a function (below: a_function_that_may_fail) where it's convenient to let it throw an error if certain conditions aren't met. The following code works well post = {} # Other Hash stuff post['Caption'] = a_function_that_may_fail rescue nil However I'd like to have post['Caption'] not even set if the function fails. I know I can do: begin post['Caption'] = a_function_that_may_fail recsue end but that feels a little excessive - is there a simpler solution?

  • How do you drop in substitute JRE classes?

    - by evilfred
    Hi, java.util.zip has well-known problems with native memory usage, so i'm trying to use a drop-in replacement called "jazzlib". unfortunately as is typical for sourceforge projects there is no documentation. If I add the jar to my classpath then Java freaks out and gives me "prohibited package name" errors because it replaced java.util.zip. How do I tell Java that this is what I want it to do?

  • conflicting declaration when filling a static std::map class member variable

    - by Max
    I have a class with a static std::map member variable that maps chars to a custom type Terrain. I'm attempting to fill this map in the class's implementation file, but I get several errors. Here's my header file: #ifndef LEVEL_HPP #define LEVEL_HPP #include <bitset> #include <list> #include <map> #include <string> #include <vector> #include "libtcod.hpp" namespace yarl { namespace level { class Terrain { // Member Variables private: std::bitset<5> flags; // Member Functions public: explicit Terrain(const std::string& flg) : flags(flg) {} (...) }; class Level { private: static std::map<char, Terrain> terrainTypes; (...) }; } } #endif and here's my implementation file: #include <bitset> #include <list> #include <map> #include <string> #include <vector> #include "Level.hpp" #include "libtcod.hpp" using namespace std; namespace yarl { namespace level { /* fill Level::terrainTypes */ map<char,Terrain> Level::terrainTypes['.'] = Terrain("00001"); // clear map<char,Terrain> Level::terrainTypes[','] = Terrain("00001"); // clear map<char,Terrain> Level::terrainTypes['\''] = Terrain("00001"); // clear map<char,Terrain> Level::terrainTypes['`'] = Terrain("00001"); // clear map<char,Terrain> Level::terrainTypes[178] = Terrain("11111"); // wall (...) } } I'm using g++, and the errors I get are src/Level.cpp:15: error: conflicting declaration ‘std::map, std::allocator yarl::level::Level::terrainTypes [46]’ src/Level.hpp:104: error: ‘yarl::level::Level::terrainTypes’ has a previous declaration as ‘std::map, std::allocator yarl::level::Level::terrainTypes’ src/Level.cpp:15: error: declaration of ‘std::map, std::allocator yarl::level::Level::terrainTypes’ outside of class is not definition src/Level.cpp:15: error: conversion from ‘yarl::level::Terrain’ to non-scalar type ‘std::map, std::allocator ’ requested src/Level.cpp:15: error: ‘yarl::level::Level::terrainTypes’ cannot be initialized by a non-constant expression when being declared I get a set of these for each map assignment line in the implementation file.

  • Win7 safe mode pretends it's Xp?

    - by Joachim Kerschbaumer
    hi there, just a question in between. a friend of mine brougth me a laptop that does not work anymore and wanted me to check whether i can do something. she told me its windows 7, and startup screen and login screen look like it. howevere, as she gets a bluescreen on startup it is only possible to boot in safe mode where the system pretends to be windows xp sp3. the system also may have 1 gig of ram but the system itself states that it has 954 mb of ram which is a value i´ve never seen before. is there everything corrupt from operating system to hardware, or am i just a newbie that does not know that windows 7 pretends to be winxp sp3 in safe mode? or is this laptop just the victim of an illegal, crazy copy of xp sold as win7? maybe some strange chinese stuff? i also recognized that the startup screen of Outlook Express is pronounced as "Outllok Express" (no typo) i´m kinda confused, maybe someone could put light into this ;) thanks
