  • Avoiding improper std::string initialization with NULL const char* using g++

    - by pachanga
    A there any g++ options which can detect improper initialization of std::string with NULL const char*? I was in the process of turning some int fields into std::string ones, i.e: struct Foo { int id; Foo() : id(0) {} }; ...turned into: struct Foo { std::string id; Foo() : id(0) {} //oooops! }; I completely overlooked bad 'id' initialization with 0 and g++ gave me no warnings at all. This error was detected in the run time(std::string constructor threw an exception) but I'd really like to detect such stuff in the compile time. Is there any way?

  • Why is it preferable to call a static method statically from within an instance of the method's clas

    - by javanix
    If I create an instance of a class in Java, why is it preferable to call a static method of that same class statically, rather than using this.method()? I get a warning from Eclipse when I try to call static method staticMethod() from within the custom class's constructor via this.staticMethod(). public MyClass() { this.staticMethod(); } vs public MyClass() { MyClass.staticMethod(); } Can anyone explain why this is a bad thing to do? It seems to me like the compiler should already have allocated an instance of the object, so statically allocating memory would be unneeded overhead.

  • How can I refactor this to use an inline function or template instead of a macro?

    - by BillyONeal
    Hello, everyone :) I have a useful macro here: #define PATH_PREFIX_RESOLVE(path, prefix, environment) \ if (boost::algorithm::istarts_with(path, prefix)) { \ ExpandEnvironmentStringsW(environment, buffer, MAX_PATH); \ path.replace(0, (sizeof(prefix)/sizeof(wchar_t)) - 1, buffer); \ if (Exists(path)) return path; \ } It's used about 6 times within the scope of a single function (that's it), but macros seem to have "bad karma" :P Anyway, the problem here is the sizeof(prefix) part of the macro. If I just replace this with a function taking a const wchar_t[], then the sizeof() will fail to deliver expected results. Simply adding a size member doesn't really solve the problem either. Making the user supply the size of the constant literal also results in a mess of duplicated constants at the call site. Any ideas on this one?

  • ASP.NET-MVC2 Preview 1: Are There Any Breaking Changes?

    - by Jim G.
    I was following Steven Sanderson's 'Pro ASP.NET MVC Framework' book. On page 132, in accordance with the author's recommendation, I downloaded the ASP.NET MVC Futures assembly, and added it to my MVC project. Then, without encouragement from the author, I downloaded, installed, and incorporated the ASP.NET MVC2 Preview 1 dlls into my project. Now, I can no longer load the website. That is, when I hit F5 in Visual Studio, I get this error. In retrospect, I think it was a really bad idea to assume that ASP.NET MVC2 Preview 1 would only be additive; but I'd like other people to weigh in. Has anyone noticed any breaking changes in ASP.NET MVC 2 Preview 1? Also - Has anyone noticed any changes that impact Castle Windsor? Also, please let me know if I should be mindful of IIS6 vs. IIS7 ramifications.

  • Automatic counter in Ruby for each?

    - by yar
    I know you Ruby people will laugh at my bad Ruby code: i=0 for blah in blahs puts i.to_s + " " + blah i+=1 end I want to use a for-each and a counter... is there a better way to do it? Note: I don't know if blahs is an array or a hash, but having to do blahs[i] wouldn't make it much sexier. Also I'd like to know how to write i++ in Ruby. Edit: Technically, Matt's and Squeegy's answer came in first, but I'm giving best answer to paradoja so spread around the points a bit on SO. Also his answer had the note about versions, which is still relevant (as long as my Ubuntu 8.04 is using Ruby 1.8.6). Edit: Should've used puts "#{i} #{blah}" which is a lot more succinct.

  • What happens to date-times and booleans when using DbLinq with SQLite?

    - by DanM
    I've been thinking about using SQLite for my next project, but I'm concerned that it seems to lack proper datetime and bit data types. If I use DbLinq (or some other ORM) to generate C# classes, will the data types of the properties be "dumbed down"? Will date-time data be placed in properties of type string or double? Will boolean data be placed in properties of type int? If yes, what are the implications? I'm imaging a scenario where I need to write a whole second layer of classes with more specific data types and do a bunch of transformations and casts, but maybe it's not so bad. If you have any experience with this or a similar scenario, what are your "lessons learned"?

  • Is there a way to disable calls to Runtime.checkRestricted on the GAE Java development server under Eclipse?

    - by Thomas Becker
    I'm one of those guys who step through their code a lot during development. Beginning with version 1.6.4 of the GAE Java development server, the server has been instrumented with calls to a function named Runtime.checkRestricted. This causes two inconveniences when I step through my code: 1) Whenever I step into a function, the debugger goes into the function Runtime.checkRestricted (for which there is no source code) at least once, often multiple times. 2) Whenever I step over a function call which has a large call tree underneath it, then it takes a very long time for the debugger to come back. (That's always a problem in the Eclipse Java debugger, but now it's really bad.) For me, all this causes a serious drain on productivity. Is there any way to disable this instrumentation, or to prevent the debugger from stepping into it? I am using Eclipse with the GAE plugin.

  • Problem requesting a HTTPS with TCL

    - by Javier
    Hi Everybody, I'm trying to do the following request using TCL (OpenACS) http::register https 443 tls::socket set url "https://encrypted.google.com" set token [http::geturl $url -timeout 30000] set status [http::status $token] set answer [http::data $token] http::cleanup $token http::unregister https The problem is that when I read the $status variable I get "eof" and the $answer variable becomes empty. I tried enabling tls V.1 http::register https 443 [list tls::socket -tls1 1] and it works only for the site https://www.galileo.edu, but not for https://encrypted.google.com. The site what I'm trying to connect is https://graph.facebook.com/me/feed?access_token=... but it doesn't work. I used curl to retrieve the contents of the pages in HTTPS and it works, I have installed OpenSSL, so I can't see the problem, there is another way to do HTTPS connections with TCL?. I can't see if this is a problem of coding (maybe I'm registered wrong the https protocol) or maybe It is a bad configuration of my server. Hope somebody helps!! Thanks!

  • C#/Resharper 5 structural search, detect and warn if any non-virtual public methods on classes with

    - by chillitom
    Hi All, I'm using LinFu's dynamic proxy to add some advice to some classes. The problem is that the proxied objects can only intercept virtual methods and will return the return type's default value for non-virtual methods. I can tell whether a class is proxied or not based whether the class or any of it's method has an interception attribute, e.g. [Transaction] Is it possible to write a ReSharper 5 structural search that would warn if any non-virtual public methods are defined on a class with an interception attribute. E.g. Ok public class InterceptedClass { [Transaction] public virtual void TransactionalMethod() { ... } public virtual void AnotherMethod() { ... } } Bad public class InterceptedClass { [Transaction] public virtual void TransactionalMethod() { ... } public void AnotherMethod() // non-virtual method will not be called by proxy { ... } } Many Thanks.

  • ASP.NET MVC Routes

    - by MVCDummy09
    Can I see one example that would make this piece of code compile? public IEnumerable<RouteBase> Routes { get { return new List<Route>() { new Route(...) } } } What would you do if RouteCollection.MapRoute() didn't exist? I'm trying to put my Controller in charge of mapping routes, not Global.asax.cs. public IEnumerable<RouteBase> Routes is a member of my Controller. If the Controller is responsible for a Route, it's a bad idea to decouple the Route by using routes.MapRoute() in Global.asax.cs.

  • Detecting a Key Press Squashed by Another Application

    - by Eric Smith
    I have a WPF application I'm planning to use as an overlay for a DirectX game (specifically Bad Company 2). I'm using WM_KEYBOARD_LL hook to detect KeyDown events so I can bring my app to the foreground when a specific button is pressed. This works perfectly except for when the game is running (I've also noticed this problem with Window's "Chess Titans" so it may be a DirectX thing). As far as I can work out, when the game detects a keyboard press, it "eats" the event and doesn't pass the CallNextHookEx() method like it should, which would allow the key press message to be moved along to the next application in the queue. I'm wondering if there's any sort of work-around to this? It seems kind of unfair that a single application can just willy-nilly eat up messages like that. Thanks! :) Relevant MSDN documentation: http://msdn.microsoft.com/en-us/library/ms644985%28VS.85%29.aspx

  • JUnit tests for POJOs

    - by Ryan Thames
    I work on a project where we have to create unit tests for all of our simple beans (POJOs). Is there any point to creating a unit test for POJOs if all they consist of is getters and setters? Is it a safe assumption to assume POJOs will work about 100% of the time? Duplicate of - Should @Entity Pojos be tested? See also Is it bad practice to run tests on a DB instead of on fake repositories? Is there a Java unit-test framework that auto-tests getters and setters?

  • Multiple complete HTTP requests stuck in TCP CLOSE_WAIT state

    - by Sean Owen
    I have a Java and Tomcat-based server application which initiates many outbound HTTP requests to other web sites. We use Jakarta's HTTP Core/Client libraries, very latest versions. The server locks up at some point since all its worker threads are stuck trying to close completed HTTP connections. Using 'lsof' reveals a bunch of sockets stuck in TCP CLOSE_WAIT state. This doesn't happen for all, or even most connections. In fact, I saw it before and resolved it by making sure to set the Connection: Close response header. So that makes me think it may be bad behavior of remote servers. It may have come up again since I moved the app to a totally new service provider -- different OS, network situation. But, I am still at a loss as to what I could do, if anything, to work around this. Some poking around on the internet didn't turn up anything I'm not already doing. Just thought I'd ask if anyone has seen and solved this?

  • Why does asp.net mvc form submits itself on button clicks when javascript function error?

    - by melaos
    hi guys, i'm new to the asp.net mvc, and while working on this, i used very basic asp.net mvc stuff like beginform, etc. i used a lot of jquery codes this round for client side validation, ajax data retrieval, and other gui works. and i used a combinations of html inputs buttons, etc and the asp.net mvc type of controls. what i noticed is that whenever i click on a button control, which sometimes are tied to either jquery oclick events, when there's a javascript error, the page will just go on and submit. why is this happening and what am i missing here? my bad for the dumb questions.. thanks

  • When do you learn from your mistakes?

    - by smayers81
    When are you supposed to learn from your mistakes in coding / design? Is it something you take with you to the next project or do you learn in the middle of your current one, sacrificing consistency for cleaner, more well-informed code? For example, my application can be distinctly demarcated down two lines of business -- say one side is for sales and the other is for marketing. Both are somewhat tied together, but as far as the team structure, use cases, developers, etc. the app consists of the Sales code and the Marketing Code. Now, say the Sales code went in first and while good-intentioned, made some bad mistakes. Should the Marketing Code follow suit and make the same mistakes for the sake of consistency or should Marketing architects and designers instead learn from the mistakes that Sales made and developer a cleaner codebase, even though Sales and Marketing are in the exact same system? Basically, do you learn from your mistakes while in a project or do you continue to pile crap on top of crap?

  • React to change on a static property

    - by Stiggler
    I'm re-writing an MXML item renderer in pure AS. A problem I can't seem to get past is how to have each item renderer react to a change on a static property on the item renderer class. In the MXML version, I have the following binding set up on the item renderer: instanceProperty={callInstanceFunction(ItemRenderer.staticProperty)} What would be the equivalent way of setting this up in AS (using BindingUtils, I assume)? UPDATE: So I thought the following wasn't working, but it appears as if Flex is suppressing errors thrown in the instanceFunction, making it appear as if the binding itself is bad. BindingUtils.bindSetter(instanceFunction, ItemRenderer, "staticProperty"); However, when instanceFunction is called, already initialized variables on the given instance are all null, which was the cause of the errors referenced above. Any ideas why this is?

  • Django view function design

    - by dragoon
    Hi, I have the view function in django that written like a dispatcher calling other functions depending on the variable in request.GET, like this: action = '' for act in ('view1', 'view2', 'view3', 'view4', ... ): if act in request.GET: action = act break ... if action == '': response = view0(request, ...) elif action == 'view1': response = view1(request, ...) elif action == 'view2': response = view2(request, ...) ... The global dispatcher function contains many variable initialization routines and these variables are then used in viewXX functions. So I feed that this is bad view design but I don't know how I can rewrite it?

  • Would a Socket Connection Outperform an Intarvaled Database Sweep and Requests?

    - by Jascha
    I'm building a small chat application to add to an existing framework. There will only be 20-50 users MAX at any one time. I was wondering if I could get away with updating a cache file containing (semi) live chat data for whichever users happen to be chatting just by performing timed queries and regular AJAX refreshes for new data as opposed to learning how to open and maintain a socket connection. I'm sure there are existing chat plug-ins out there. But I just had a hell of a time installing one and I could see building the whole damn thing taking just as much time as plugging one in. Am I off to a bad start? Thanks in advance -J (p.s. this is a semi closed network behind a php login so security isn't a great concern)

  • Would an ORM have any way of determining that a SQLite column contains date-times or booleans?

  • What ports does Advantage Database Server need?

    - by asherber
    I have an application which uses ADS and I am attempting to deploy it in a Windows network environment with a rather restrictive firewall. I am having a problem configuring firewall ports appropriately. ADS lives on \server, and it's listening on port 1234. When \client tries to connect to \server\tables, I get Error 6420 (Discovery process failed). When \client tries to connect to \server:1234\tables, I get error 6097, bad IP address specified in the connection path. \server is pingable from \client, and I can telnet to \server:1234. If I try to connect from a client machine inside the firewall, either connection path works fine. It seems there must be something else I need to open in the firewall. Any ideas? Thanks, Aaron.

  • Programming challenge: can you code a hello world program as a Palindrome?

    - by Assaf Lavie
    So the puzzle is to write a hello world program in your language of choice, where the program's source file as a string has to be a palindrome. To be clear, the output has to be exactly "Hello, World". Edit: Well, with comments it seems trivial (not that I thought of it myself of course [sigh].. hat tip to cobbal). So new rule: no comments. Edit: I feel kind of bad editing someone else's question to say this, but it will eliminate a lot of non-palindromes that keep popping up, and I'm tired of seeing the same simple mistake over and over. The following is NOT a palindrome: ()() The following IS a palindrome: ())( Brackets, parenthesis, and anything else that must match are a major barrier to palindrome-ing, yes, but that doesn't mean you can ignore them and post non-palindrome answers. Languages represented thus far: C, C++, Bash, elisp, C#, Perl, sh, Windows shell, Java, Common Lisp, Awk, Ruby, Brainfuck, Funge, Python, Machine Language, HQ9+, Assembly, TCL, J, php, Haskell, io, TeX, APL, Javascript, mIRC Script, Basic, Orc, Fortran, Unlambda, Pseudo-code, Befunge, CFML, Lua, INTERCAL, VBScript, HTML, sed, PostScript, GolfScript, REBOL, SQL

  • Weaknesses of Hibernate

    - by Sinuhe
    I would like to know which are the weak points of Hibernate 3. This is not pretended to be a thread against Hibernate. I think it will be a very useful knowledge for decide if Hibernate is the best option for a project or for estimating its time. A weakness can be: A bug Where JDBC or PLSQL are better Performance issues ... Also, can be useful to know some solutions for that problems, better ORM or techniques, or it will be corrected in Hibernate 4. For example, AFAIK, Hibernate will have a very bad performance updating 10000 rows comparing to JDBC in this query: update A set state=3 where state=2

  • Open Source Code Integrity - How does quality assurance work?

    - by rockinthesixstring
    I've thought about this before and this topic has often steered me away from Open Source projects. Recently DotNetPanel has changed it's name to WebSitePanel and gone Open Source. The rumor mill is speculating that Microsoft is behind this. My question (in multi-part) is quite simple. Can somebody please explain to me how quality assurance works on Open Source projects? How can a closed application get "only better" when Open Source? Doesn't the "too many cooks in the kitchen" theory apply when too many developers contribute (possibly bad) code to a project?

  • Debuging to simulator crashes with "exited with status 5" unless I have breakpoint

    - by tigermain
    For some reason the app I am working on has very bad PMT! Literally! Most of the time I cannot debug using the simulator without putting a breakpoint in my AppDelegate. If I don't it exists with "status 5". If I put a break point in and simple continue it works perfectly well, it also works if I run the app in the simulator when not connected to the GDB. I have tried the source on a second machine with exactly the same results. I dont have this issue building to the device?!?!?! Thanks

  • Job conditions conflicting with personal principles on software-development - how much is too much?

    - by Baelnorn
    Sorry for the incoming wall'o'text (and for my probably bad English) but I just need to get this off somehow. I also accept that this question will be probably closed as subjective and argumentative, but I need to know one thing: "how much BS are programmers supposed to put up with before breaking?" My background I'm 27 years old and have a B.Sc. in Computer engineering with a graduation grade of 1.8 from a university of applied science. I went looking for a job right after graduation. I got three offers right away, with two offers paying vastly more than the last one, but that last one seemed more interesting so I went for that. My situation I've been working for the company now for 17 months now, but it feels like a drag more and more each day. Primarily because the company (which has only 5 other developers but me, and of these I work with 4) turned out to be pretty much the anti-thesis of what I expected (and was taught in university) from a modern software company. I agreed to accept less than half of the usual payment appropriate for my qualification for the first year because I was promised a trainee program. However, the trainee program turned out to be "here you got a computer, there's some links on the stuff we use, and now do what you colleagues tell you". Further, during my whole time there (trainee or not) I haven't been given the grace of even a single code-review - apparently nobody's interested in my work as long as it "just works". I was told in the job interview that "Microsoft technology played a central role in the company" yet I've been slowly eroding my congnitive functions with Flex/Actionscript/Cairngorm ever since I started (despite having applied as a C#/.NET developer). Actually, the company's primary projects are based on Java/XSLT and Flex/Actionscript (with some SAP/ABAP stuff here and there but I'm not involved in that) and they've been working on these before I even applied. Having had no experience either with that particular technology nor the framework nor the field (RIA) nor in developing business scale applications I obviously made several mistakes. However, my boss told me that he let me make those mistakes (which ate at least 2 months of development time on their own) on purpose to provide some "learning experience". Even when I was still a trainee I was already tasked with working on a business-critical application. On my own. Without supervision. Without code-reviews. My boss thinks agile methods are a waste of time/money and deems putting more than one developer on any project not efficient. Documentation is not necessary and each developer should only document what he himself needs for his work. Recently he wanted us to do bug tracking with Excel and Email instead of using an already existing Bugzilla, overriding an unanimous decision made by all developers and testers involved in the process - only after another senior developer had another hour-long private discussion with him he agreed to let us use the bugtracker. Project management is basically not present, there are only a few Excel sheets floating around where the senior developer lists some things (not all, mind you) with a time estimate ranging from days to months, trying to at least somehow organize the whole mess. A development process is also basically not present, each developer just works on his own however he wants. There are not even coding conventions in the company. Testing is done manually with a single tester (sometimes two testers) per project because automated testing wasn't given the least thought when the whole project was started. I guess it's not a big surprise when I say that each developer also has his own share of hundreds of overhours (which are, of course, unpaid). Each developer is tasked with working on his own project(s) which in turn leads to a very extensive knowledge monopolization - if one developer was to have an accident or become ill there would be absolutely no one who could even hope to do his work. Considering that each developer has his own business-critical application to work on, I guess that's a pretty bad situation. I've been trying to change things for the better. I tried to introduce a development process, but my first attempt was pretty much shot down by my boss with "I don't want to discuss agile methods". After that I put together a process that at least resembled how most of the developers were already working and then include stuff like automated (or at least organized) testing, coding conventions, etc. However, this was also shot down because it wasn't "simple" enought to be shown on a business slide (actually, I wasn't even given the 15 minutes I'd have needed to present the process in the meeting). My problem I can't stand working there any longer. Seriously, I consider to resign on monday, which still leaves me with 3 months to work there due to the cancelation period. My primary goal since I started studying computer science was being a good computer scientist, working with modern technologies and adhering to modern and proven principles and methods. However, the company I'm working for seems to make that impossible. Some days I feel as if was living in a perverted real-life version of the Dilbert comics. My question Am I overreacting? Is this the reality each graduate from university has to face? Should I betray my sound principles and just accept these working conditions? Or should I gtfo of there? What's the opinion of other developers on this matter. Would you put up with all that stuff?
