Is there a single, simple facade to getting human readable system info from the CLI?

  • Application trying to use the wrong shared library

    - by Josh
    I'm having a problem with a program (quartus) running on my ubuntu machine. I'm getting the following error. quartus: symbol lookup error: /usr/lib/i386-linux-gnu/libXi.so: undefined symbol: XESetWireToEventCookie I have the correct libXi.so.6.0.0 file but no matter where I put it, the OS won't use it unless I apt-get remove libxi-dev, but a lot of software uses this libXi. What I want to do is add some sort of exception to the dynamic linker so that quartus uses the libXi.so that it needs and everything else still uses the one in /usr/lib/i386-linux-gnu. Thanks!

  • How do I deal with the problems of a fast side-scroller?

    - by Ska
    I'm making a side scrolling airplane game and when I begin going very fast I begin to experience some problems as a player: Elements are not distinguishable, like power-ups from bullets, etc I start to feel dizzy and uncomfortable There isn't enough time to see what's coming How can I sort this out? Do I use less details in all the grahpics? Tiny Wings has the same horizontal movement speed as in my game but it doesn't suffer from these problems. Are there any other really fast side-scrollers I could take as a reference?

  • What's the simplest way to create a page with dynamic elements?

    - by ElendilTheTall
    I'm developing a site, part of which lists training courses with dates and prices. Every year the dates and prices change, which would mean loads of manual code editing to update the pages. What I'd like to do is have a database containing the relevant information, which the course pages then reference, so we can just update the database rather than the HTML. My experience lies in static design - so, what is a simple way to achieve this?

  • Use controller in view in MVC

    - by gavri
    I have a problem convincing my team mates why we shouldn't use (directly reference) the controller in the view when developing components in the spirit of MVC. I have invoked decoupling and natural intuition, but still those arguments didn't get through. They say, in their defense, that this is a normal compromise. What arguments are convincing? Or they are right? How can the practice of using the controller in the view could affect a project on the long run?

  • Learning the nuances of a language (C++)

    - by prelic
    So I'm a recent college graduate, and I really enjoy working in C++; I worked with it a lot in school, and would like to pursue a career writing in C or C++. The problem I'm having is that I'm trying to learn the nuances of C++. I'm not talking about the basics, or even advanced concepts like templates, namespaces, etc...I'm talking about the real nitty-gritty stuff like undefined behavior and stuff like that. When I'm interviewing, and they put a bizarre piece of C++ code in front of me, and ask me what the output will be, I want to be able to nail those questions. Obviously experience is a great way to learn, but when I write code for practice, I [obviously] know what it does. Reading open-source projects have been good practice, but I find that there tends to be an enormous learning curve just understanding the organization of the code (because the projects tend to be large). So basically what I'm asking is, what should I do now? Any tips are greatly appreciated!

  • Why DbContext object shouldn't be referred in Service Layer?

    - by nazmoonnoor
    I've been looking for some implementations of Service Layer and Controller interaction in blogs and in some open source projects. All of them seem to refer DbContext object in repository classes but avoided to use in service classes. Service classes essentially using a IQueryable<T> references of DbSet<T>. I want to know why this practice is good and why DbContext shouldn't have a reference in Service Layer.

  • Finding Tools Guidance in OUM

    - by user716869
    OUM is not tool – specific. However, it does include tool guidance.  Tool guidance in OUM includes: a mention of a tool that could be used to complete a specific task(s) templates created with a specific tool example work products in a specific tool links to tool resources Tool Supplemental Guides So how do you find all this helpful tool information? Start at the lowest level first – the Task Overview.  Even though the task overviews are written tool-agnostic, they sometimes mention suggestions, or examples of a tool that might be used to complete the task.  More specific tool information can be found in the Task Overview, Templates and Tools section.  In some cases, the tool used to create the template (for example, Microsoft Word, Powerpoint, Project and Visio) is useful. The Templates and Tools section also provides more specific tool guidance, such as links to: White Papers Viewlets Example Work Products Additional Resources Tool Supplemental Guides If you’re more interested in seeing what tools might be helpful in general for your project or to see if there is any tool guidance for a specific tool that your project is committed to using, go to the Supplemental Guidance page in OUM.  This page is available from the Method Navigation pull down located in the header of almost every OUM page. When you open the Supplemental Guidance page, the first thing you see is a table index of everything that is included on the page.  At the top of the right column are all the Tool Supplemental Guides available in OUM.  Use the index to navigate to any of the guides. Next in the right column is Discipline/Industry/View Resources and Samples.  Use the index to navigate to any of these topics and see what’s available and more specifically, if there is any tool guidance available.  For example, if you navigate to the Cloud Resources, you will find a link to the IT Strategies from Oracle page that provides information for Cloud Practitioner Guides, Cloud Reference Architectures and Cloud White Papers, including the Cloud Candidate Selection Tool and Cloud Computing Maturity Model. The section for Method Tool and Technique Cross References can take you to the Task to Tool Cross Reference.  This page provides a task listing with possible helpful tools and links to more information regarding the tools.  By no means is this tool guidance all inclusive.  You can use other tools not mentioned in OUM to complete an OUM task. The Method Tool and Technique Cross References can also take you to the various Technique pages (Index and Cross References).  While techniques are not necessarily “tools,” they can certainly provide valuable assistance in completing tasks. In the Other Resources section of the Supplemental Guidance page, you find links to the viewlets and white papers that are included within OUM.

  • Visual Studio 2010 Web Development Improvements

    - by Aamir Hasan
    VS2010 emulates what is available in previous framework versions through reference assemblies. These assemblies contain metadata that describes functionality available in previous versions. VS2010 itself uses the .NET 4 framework, so when adding multitargeting support the team decided against running a previous framework version inside the same process. When your application is compiled to 100 percent guarantee application compatibility, previous compiler versions are used.Web development in Visual Studio 2010 has been enhanced for greater CSS compatibility, increased productivity through HTML and ASP.NET markup snippets and new dynamic IntelliSense JavaScript.Improved CSS CompatibilityHTML and JavaScript SnippetsJavaScript IntelliSense Enhancements

  • Managing a Web Portal

    - by A competent translator
    After skimming almost all questions tagged "books" here at Pro Webmasters to find a book on managing web portals I found references to general web mastering. Are there books on managing and curating content of public web portals , i.e. a governmental portal for a given department or agency ? I need a reference on the day-to-day management and best practices of a portal and its content. Also welcomed are references on managing multilingual portals.

  • What are the differences between Special Edition and the Third Edition of Stroustrup's The C++ Programming Language?

    - by TheBlueCat
    I'm buying a few C++ books after moving from Java. I obviously want to read the reference manual from the man himself, though I cannot tell the difference between these two editions. The special edition is ten pages shorter than the third edition. However, the special edition is recommended over the third edition and it seems this version covers the ASCII standard when the other edition does not. Can anyone shed a bit of light on this?

  • Installing ImageMagick for C(++) on Ubuntu 12.10

    - by user167747
    I'm having a hard time installing the ImageMagick software for Ubuntu 12.10. So, I want the C and C++ API, not much more. Now when I go to imagemagick.org, they have a binary package for unix, namely an rpm. When I download and launch it, RPM complains that firstly I should be using alien, and secondly there are like 10000 missing dependencies. If I use alien to create a deb file, and the install it via the software center, the package does indeed install, but only the command line interface - no includes, anything. Same with apt-get imagemagick. (BTW - wtf, they don't have support for ubuntu?) I tried compiling from source (which I shoudn't be doing anyway - I'm not expecting much customization am I?), and then the includes are present, but the programs won't compile complaining about "undefined reference" and then a list of everything that isn't pure C (and I'm using the command imagemagick.org told me to use, namely cc -o wand pkg-config --cflags --libs MagickWand wand.c) so clearly I'm doing something wrong. Any help would be much appreciated.

  • C++ linkage error . What am I doing wrong ? [migrated]

    - by nashmaniac
    So, this is the first time I actually separated a single program into a header and two .cpp files . But I think I am getting an linkage error . Heres how the directory looks . (heres a link to my image I dont have enough rep to post image in the question) http://i.stack.imgur.com/sbT4V.png The main.cpp is my main source file where all the calling functions and other important stuff goes . In functions.cpp I have all my functions , in the coordin.h file I have the function prototypes and structures and Constants . Everything is ok no typo nothing I have checked everything . But I am getting an undefined reference to function error. I have included the coordin.h file too . Do you think the functions.cpp file needs to go somewhere else I mean is the compiler not looking inside that file ? Thanks !
