  • How does one view the "inline docs" of a .cpp file?

    - by Mala
    I have cpp files peppered with comments such as the following before every function: /** * @brief Set the normal and expansion handshake timeouts. * * @param wm Array of wiimote_t structures. * @param wiimotes Number of objects in the wm array. * @param normal_timeout The timeout in milliseconds for a normal read. * @param exp_timeout The timeout in millisecondsd to wait for an expansion handshake. */ I assume from the format that there has to be some way of exporting this into a "friendly" format, perhaps html, which can then be read in a manner similar to the Java API. How would I do this? (I'm on Windows 7, running MS Visual Studio 2010)

  • Setting Environment Variable for Tomcat 6 Servlet

    - by amaevis
    I'm using Ubuntu's default installation of Tomcat 6. I'm deploying a ROOT.war, and trying to set an environment variable specific to it, i.e. accessible from System.getenv() in the Servlet.init(config). According to the docs (http://tomcat.apache.org/tomcat-6.0-doc/config/context.html), I can specify this in a Context element in conf/Catalina/localhost/ROOT.xml. I've created that with these contents: <Context> <Environment name="FOO" value="bar" type="java.lang.String" override="false"/> </Context> And I've deployed the webapp as usual, i.e. to webapps/ROOT.war. Server.getenv("FOO") in the Servlet.init(config) still returns null. What am I missing?

  • What OS for Eee PC ?

    - by crivateos
    Hello. I've just bought new Eee PC 1005 (with Atom N450, 250GB and 2GB memory) without any pre-installed system. Now I'd like to install windows and linux distribution on in. What should I choose ? I am a programmer and web designer, so I need Java IDE , Python interpreters, and Photoshop (on windows). Will Win 7 Pro 32bit work ?Or should I choose Windows XP ? And what about linux distro ? Ubuntu, Eeebuntu, Ubuntu netbook edition ? btw is it true that linux's grub overrides mbr so that hardware system restore doesn't work ?

  • How much sense does it make for a veteran .Net developer to move to ROR professionally?

    - by SharePoint Newbie
    Hi, I consider myself a moderately skilled (definitely not stupid) .Net developer. Over the past 5 years I've been working with ASP.Net, ASP.Net MVC, SharePoint, WPF, Silverlight, RDBMS (SQL Server and Oracle). I maintain/contribute a couple of .Net OSS. I've also picked up F# and Haskell over the previous year. I am currently employed at one of the better (best) software firms out there and would surely love to continue working here. However over the past 6 months opportunities in .Net have mostly dried up and all new work is headed towards ROR (and whatever is left towards Java). I have never been apprehensive about learning a new stack/language for fun and have previously picked up Haskell and Python in my free time. I am however apprehensive as to what impact moving to a new entirely different stack would have on my career. What would you do: Change jobs if you don't find anything on .Net soon. Try out the ROR stack for some time. If you find that its not your cup of tea, move back. (How would this impact my career and job opportunities in the longer run?) Also it would be very helpful if there are any ASP.Net MVC folks who have switched over to ROR professionally who can share their experiences. Edit: I have not done any development on a *nix box before. I've however used Ubuntu for fun and games. Sorry if this sounds subjective.

  • How to progress far enough in a year [on hold]

    - by xCasper
    So I came to a realization the other day, I graduate in a year. I will have completed my four year degree in about two and a half (I went to a school that goes full time year round). Anyway, I want to get a job, as a programmer, when I graduate. The problem is, I feel like I am no where near ready. In the last year I cant say I have made any spectacular projects. I know that my advanced programming courses are coming up, but by the time I take them, I will be graduating in 6 months. Not nearly enough time to really take what I learn, apply it, and create something to show for myself. I want to push myself ahead of the game; mainly because my major is Computer Information Systems, so the focus is not programming. In fact, I only get, 4 programming classes. Before anyone says anything, CIS is the closest to a programming major at my school that I am able to do. So the questions come down to this: 1) What can I do to really step up the speed at which I progress (on my own) 2) Should I be aiming for a certain amount of projects in my "Portfolio." 2a) Should they be big projects? P.S: The language we have used in school in c++, I do take a Java class in the spring, and .net over Summer; if any of that matters for anything.

  • Significant amount of the time, I can't think of a reason to have an object instead of a static class. Do objects have more benefits than I think?

    - by Prog
    I understand the concept of an object, and as a Java programmer I feel the OO paradigm comes rather naturally to me in practice. However recently I found myself thinking: Wait a second, what are actually the practical benefits of using an object over using a static class (with proper encapsulation and OO practices)? I could think of two benefits of using an object (both significant and powerful): Polymorphism: allows you to swap functionality dynamically and flexibly during runtime. Also allows to add new functionality 'parts' and alternatives to the system easily. For example if there's a Car class designed to work with Engine objects, and you want to add a new Engine to the system that the Car can use, you can create a new Engine subclass and simply pass an object of this class into the Car object, without having to change anything about Car. And you can decide to do so during runtime. Being able to 'pass functionality around': you can pass an object around the system dynamically. But are there any more advantages to objects over static classes? Often when I add new 'parts' to a system, I do so by creating a new class and instantiating objects from it. But recently when I stopped and thought about it, I realized that a static class would do just the same as an object, in a lot of the places where I normally use an object. For example, I'm working on adding a save/load-file mechanism to my app. With an object, the calling line of code will look like this: Thing thing = fileLoader.load(file); With a static class, it would look like this: Thing thing = FileLoader.load(file); What's the difference? Fairly often I just can't think of a reason to instantiate an object when a plain-old static-class would act just the same. But in OO systems, static classes are fairly rare. So I must be missing something. Are there any more advantages to objects other from the two that I listed? Please explain.

  • How to set up server to be accessed from mobile devices [closed]

    - by Kgrover
    I need to set up a server that will eventually be accessed from an Android application. I don't have experience with how to go about this, but I've seen MySQL servers (Amazon EC2). I would need to store data on the server remotely (again, from a mobile device) and fetch it to display. What would be the best kind of server to use? I'm guessing I would only need around 50 GB of space. Is it possible to use a network drive and set that up as a remote server with an IP address? I would need to upload and extract data through java on Android. This is my first question on ServerFault, and I'm not sure if it's the appropriate forum. If not, please redirect me.

  • Too many files open issue (in CentOS)

    - by Ram
    Recently I ran into this issue in one of our production machines. The actual issue from PHP looked like this: fopen(dberror_20110308.txt): failed to open stream: Too many open files I am running LAMP stack along with memcache in this machine. I also run a couple of Java applications in this machine. While I did increase the limit on the number of files that can be opened to 10000 (from 1024), I would really like to know if there is an easy way to track this (# of files open at any moment) as a metric. I know lsof is a command which will list the file descriptors opened by processes. Wondering if there is any other better (in terms of report) way of tracking this using say, nagios.

  • JBoss 4.2.3 Won't Start

    - by Thody
    Hi, I'm trying to start a new installation of JBoss 4.2.3, and it's getting as far as "INFO [Server] Core system initialized", then hanging for several minutes. There is a Java process running, but only at ~35%. Also, looking at the boot.log, there are no entries after ~1s after starting the boot. Any ideas what might be up? Update: After about 10 minutes, I got a handful of garbage collection warnings: GC Warning: Repeated allocation of very large block (appr. size 512000): May lead to memory leak and poor performance.

  • How is Javascript parsed/executed in a web browser exactly?

    - by ededed
    For example when I access web server likely Javascript will execute. From there on, how will the browser parse the Javascript, or "execute" the functions, the memory used, etc. How will the browser "handle" all of that? Does it act like a compilation lexer in that it passes line by line and generates object code, or does it use the DOM, and other specifications to handle memory, etc. Also, in terms of updating the page, and alterior concurrent executions as well, such as Flash, HTML, Java, etc. Point be simplified, how does the browser handle the scripts, the memory, and the logic on page from a javascript file?

  • Tomcat SSL integration issue

    - by small_ticket
    Hi all, I've bought a wildcard ssl certificate from a company, i sent them the csr file and they send me two certificate files namely CA.txt and com_sertificate. I've searched on web and find some tutorials about tomcat and ssl but i can not accomplish with these two files. All that tutorials mention about different files that i don't have. (I asked about this process to the company that i bought certificates but they said they don't have any knowledge about tomcat integration) Is there anyone that has an idea about this? p.s I'm using ubuntu 8.04 server, Java 1.6 and tomcat 6

  • Learning project Custom c# Cms [closed]

    - by user313378
    I want to start new project customCms, cause I think it's a good starting point to implement my collected knowledge from c#, ddd, nhibernate, mvc3, js. It will be great if I hear some guidlines from expirienced users here. I will use C# ASP.NET MVC3 razor view engine. Also I was thinking of NHibernate ORM, I dont know if using Nhibernate will cause performanse down. Initially MSSQL 2008 will be used, but using ORM layer cause that I can switch to some other db with no pain. I was thinking to create News entity which will have properties Id Name Created Updated IntroText Content Title Author ListPhotos Every input will be validated with untroub. java script on the view, and it will be validated on db level as well. Maybe it is best approach to create some interface which will be implemented by my cmsClient entity like NewsEntity. In this interface will be included everything it should be requested from my client in future. At least some stuff which are not included in entity right now, consumed data by rss feed, wcf, etc. So basically everything you think its good idea from documentating project, to coding. Everyone is welcomed to brainstorm for custom cms.

  • How to learn to program [on hold]

    - by user94914
    I went to a community college and got a degree in computer science, but I found out I only learn very little about programming. As a result I landed byself a office assistant work (for a year now), I want to study on my own and apply for some internship / very entry level development job. I am wondering how should a person learn to program now? I feel that I might not doing it correctly, I understand everyone has a different approach, but I am really clueless on what to do, as it seems I am 5-10 years away. 1) Read the old college programming textbook cover to cover, learn every single concepts, do all the practice problems and master them (1-2 times until error free). Currently reading this java book 2) Work on any project, keep on googling and reading tutorials (including the books on that specific language). I have been doing 1, but the progress is really slow, about 2-5 pages / hour, over a 1000+ page book, I felt really discouraged. I have a few of them to go through (data struction, analyis algorthim, computer theory, operating system.) I wonder is this the right method to do? I know it is going to take time, but I am hoping to get some advice from current programmers.

  • When and how does one become a good programmer these days? [closed]

    - by YoungMoney
    I mean, good enough to make software people want and get paid for it. Maybe even good enough to launch a company or something. I'm also concerned that I'm not applying the finer points of my algorithms/data structures/software design knowledge. Background: I'm 20 and have been struggling with programming for about two years now, trying to become a software engineer. I started with a few university courses that I did quite poorly in. I learned how to make websites with HTML/JavaScript and PHP/MySQL, but feel like I know very relevant theory for making good databases - how does something like Facebook serve hundreds of millions of people? What would be smart ways to store data? I don't know. Now I'm doing some android application development, but again I have no idea about good Java design theory (I use static variables like they're going out of fashion) and feel more like I'm gluing stuff together and letting Eclipse slowly autocomplete my project. In short, I'm not sure if I'm becoming a legitimate software developer or just "doing what's cool". At least I've taken some data structures and Algorithms courses and plan to take more in the next years. But I'm having a really tough time applying this stuff to my fun little apps that I'm building. Every language higher level than C++ seems to have its own quicksort function already built-in, for example. Similarly, I can't remember ever needing to implement a linked-list, heap, binary tree, or or worry about pointers and memory management. But maybe this is a good thing so that I focus on other things? I'm not too sure what those other things are though. Hopefully something more than building another photo sharing app. Anyways that's it for me, I look forward to your responses!

  • Good Wiki for SMB with Customer Interaction

    - by wag2639
    Hey, I know there's a bunch of wiki questions already but I was wondering if anyone could recommend a good wiki thats good for use internally and can be access by some clients? Must be free (F/OSS preferred), Ubuntu (9.10+) compatible, and have per-page permissions. I setup MediaWiki and its fine for internal use but I don't know how, without some severe hackery, how to restrict a client to just view one page and all the images on it and css. It'll be worse when they ask to be able to modify it as well. Edit: also, please no java solutions

  • Secondment promotion promises

    - by user75460
    I'm a Java developer at a large FTSE 30 company. My line manager approached me and asked if I'd like to be the teams lead developer. I was keen to accept. Initially he said I'd be acting-up for 3 months, then changed his tune and said I would be doing a 6 month secondment. During this time, he has got himself promoted and I have a new line manager. I have been very successful during this secondment and reviews have been overwhelmingly positive: both from my former line manager and current line manager. However, six months on, no lead role has been created in the organization and a new director has re-organised the structure of the team: two senior roles (senior Android and senior iOS) are going to be created. I feel a bit put-out that my secondment has amounted to nothing. I could have just done nothing and then applied for the senior role 6 months later (which I feel aren't as marketable as Lead developer). During my secondment I have basically become TA, senior developer, line manager and general go-to guy for all things (across Android and iOS). What do you think I should do, and has my company abused it's position? I feel they have offered a secondment to a role that they never really planned to create. During this time I have received no financial benefit for doing a more senior role.

  • C programming multiple storage backends

    - by ahjmorton
    I am starting a side project in C which requires multiple storage backends to be driven by a particular piece of logic. These storage backends would each be linked with the decision of which one to use specified at runtime. So for example if I invoke my program with one set of parameters it will perform the operations in memory but if I change the program configuration it would write to disk. The underlying idea is that each storage backend should implement the same protocol. In other words the logic for performing operations should need to know which backend it is operating on. Currently the way I have thought to provide this indirection is to have a struct of function pointers with the logic calling these function pointers. Essentially the struct would contain all the operations needed to implement the higher level logic E.g. struct Context { void (* doPartOfDoOp)(void) int (* getResult)(void); } //logic.h void doOp(Context * context) { //bunch of stuff context->doPartOfDoOp(); } int getResult(Context * context) { //bunch of stuff return context->getResult(); } My questions is if this way of solving the problem is one a C programmer would understand? I am a Java developer by trade but enjoy using C/++. Essentially the Context struct provides an interface like level of indirection. However I would like to know if there is a more idiomatic way of achieving this.

  • Working in Germany (Munich) [closed]

    - by adri
    My husband and I are relocating to Munich in August (He's German). I have been looking for jobs online since I heard that software developers are in great demand. And by the looks of it, seems to be correct. There are lots of offers on line but I have a problem, my german is not spectacular. I would rate it as basic. Good to be a tourist but not good to write anything formal, not even my cover letter. So I was wondering how hard is really going to be to find a job for me with virtually no german (I'm studying, but good german is not going to happen over night). Also, would it be possible to secure a job before arriving to Germany? I have nearly 10 years of working experience developing software, mostly in .net (c#, vb, winForms, asp.net) but I also know java. 3 years experience as a team leader for groups of up to 8 people. In the last couple of years I've been working mostly on digitalization of documents (such as birth certificates and the like) but I'm more than willing to try other fields Also I speak English, Spanish, Italian, a bit of portuguese and of course a bit of german.

  • Program to Queue Files for Copy/Move/Delete in linux?

    - by laliga
    I've search the net for Linux's answer to something like Teracopy (Windows)... but could not find anything suitable. The closest things i got are: Krusader. Mentioned in their features but indicated as 'not implemented yet'. MiniCopier. A java based app http://a.courreges.free.fr/projets/minicopier/minicopier-en.php rsync is not an option. Can someone recommend me a simple file copy tool that can queue files for copy/move/delete? Preferably if I can drag and drop from Nautilus. If something like this does not exist, can someone please tell me why? ...am I the only person that needs something like this?

  • Ubuntu server security; Is this enough?

    - by Camran
    I have a classifieds website, which uses php5 and mysql, and also java (solr). I am new to linux and VPS... I have installed SSH, and I have installed IPtables, and also I have PuTTY which I use as a terminal. Also, Filezilla is installed on my computer, and whenever I connect to my VPS, the "host" field in Filezilla says "Sftp://ip-adress" so I am guessing it is a safe connection. I used this command to find out if I had SSHD installed: whereis sshd and it returned some places where it actually was installed. So I havent actually installed it. Now, my Q is, is this enough? What other security measures should I take? Any good articles about security and how to set it up on a VPS? Remember, I have a windows xp OS on my laptop, but the OS for my VPS is Ubuntu 9.10. Also, I have apache2 installed... Thanks
