  • Is there benefit to maintain a large project with bad code?

    - by upton
    I'm currently maintain a large project with more than 100000 LOC. The code use the MFC as its framework, in genral, it only has interface part which heavily use the mfc api and a business logic part which full of bad code, confusing logic. The company has some small features delivered to the customer each year(most features are adding code to exisiting project, finding some reference of some api or variable and it' s no different with fixing 3-4 bugs ), most of the tasks are to resove issue and optimize performance . Like other company with maintaining position, it value people who knows much logic about its product. There are people who can quickly finish the job on such project, is it worth to train myself like such a programmer? Is there benifits to work on such project for a long time?

  • Unity freezes when laptop screen is closed

    - by Giacky98
    I have an Asus laptop running Ubuntu 12.04. It's configured to do nothing when the laptop screen is closed. But sometimes, when I close the screen and when I reopen it, after I move the mouse to reactivate the screen, my Unity interface is frozen and I can't click on anything. I can move the cursor, and if there's a music playing it keeps playing, but I can't click on anything. I can open a bash shell typing Ctrl+Alt+F2, but there I don't know what to do, I can only login and type sudo reboot to reboot the machine... Is there someone that has the same problem or that knows the solution?

  • Win7 installation on VirtualBox

    - by Will
    I have Ubuntu 12.04 installed on my machine. I also installed Virtualbox so that I can run windows 7. I set my virtual box with 4 GB RAM and 25 GB virtual HDD and after I press Start, it doesnt boot from the windows dvd in the optical drive, but instead i get this error: Failed to open a session for the virtual machine win7. VT-x features locked or unavailable in MSR. (VERR_VMX_MSR_LOCKED_OR_DISABLED). Result Code: NS_ERROR_FAILURE (0x80004005) Component: Console Interface: IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb} Do you have any idea what is it and how I could overcome this? Thank you!

  • How to morph from a programmer noob to a guru?

    - by didxga
    I have been a programmer for two years, and i am getting hard to level up my skill especially working at legacy code maintenance right now. I think working hard is not enough to elevate my skill, because there are ton of opensource around us, the preoject i have been involved are all mixture of opensources --- from front end to back end from presentation tier to business logic tier. My work is just gluing all these together or something fewer complex which is to collect data from UI to logic module then retrieve the data processed and put it to UI. Sometime there is a need to add some simple logic(like assembling the data to a form that fit business logic interface) while transport data. Could you please give me any suggestion what should i do on the side to improve my skill? Thanks!

  • How to display lyrics that are stored in MP3-Tag?

    - by Der_Techniker
    How can I achieve that goal? I tried many players - banshee, rhythmbox, amarok, exaile... none of them displays lyrics that are already stored in the mp3. They always try to fetch lyrics from the internet. Interestingly, banshee supports STORING lyrics into the mp3 but not READING - I find that annoying... One player though does it properly - gmusicbrowser. But this piece of software has a so confusing user interface - I don't wanna use it. Any ideas?

  • Email forwarding to gmail accounts instead of maintaining a mail server?

    - by user01
    I want to set up 4-5 email addresses on my newly purchased domain(from namecheap.com), for team size of just 2-3 people. But I really don't want to maintain my own mail server(don't have the experience as well as want to avoid the expenses involved, may be I could have kept the mail server alongside my webapp on the web server, but I would avoid). So I came across a workaround option to forward the emails. Thus I could setup email forwarding from namecheap's management console to my free gmail accounts. So all my emails would come to gmail account, convenient & familiar interface as well free. Are there any serious drawbacks of this approach ?

  • All traffic is passed through OpenVPN although not requested

    - by BFH
    I have a bash script on a Ubuntu box which searches for the fastest openvpn server, connects, and binds one program to the tun0 interface. Unfortunately, all traffic is being passed through the VPN. Does anybody know what's going on? The relevant line follows: openvpn --daemon --config $cfile --auth-user-pass ipvanish.pass --status openvpn-status.log There don't seem to be any entries in iptables when I enter sudo iptables --list. The config files look like this: client dev tun proto tcp remote nyc-a04.ipvanish.com 443 resolv-retry infinite nobind persist-key persist-tun persist-remote-ip ca ca.ipvanish.com.crt tls-remote nyc-a04.ipvanish.com auth-user-pass comp-lzo verb 3 auth SHA256 cipher AES-256-CBC keysize 256 tls-cipher DHE-RSA-AES256-SHA:DHE-DSS-AES256-SHA:AES256-SHA

  • Architecting persistence (and other internal systems). Interfaces, composition, pure inheritance or centralization?

    - by Vandell
    Suppose that you need to implement persistence, I think that you're generally limited to four options (correct me if I'm wrong, please) Each persistant class: Should implement an interface (IPersistent) Contains a 'persist-me' object that is a specialized object (or class) that's made only to be used the class that contains it. Inherit from Persistent (a base class) Or you can create a gigantic class (or package) called Database and make your persistence logic there. What are the advantages and problems that can come from each of one? In a small (5kloc) and algorithmically (or organisationally) simple app what is probably the best option?

  • Any pre-rolled System.IO abstraction libraries out there for Unit Testing?

    - by Binary Worrier
    To test methods that use the file system we need to basically put System.IO behind a set of interfaces that we can then mock, I do this with a DiskIO class and interface. As my DiskIO code gets larger (and the grumblings from the we're unconvinced about this TDD thing crowd here in work get louder), I went looking for a comprehensive open source library that already does this and found . . . nothing. I may be looking in the wrong place or have approached this problem in completely the wrong way. I can't be the only idiot in this position, do these libraries exist, if so where are they? Any you've used and would recommend? Thanks P.S. I'm happy with my current approach i.e. starting with what we need, and adding only when the need arises. Unfortunately the we're unconvinced about this TDD thing crowd remain unconvinced, and think that I can't be right.

  • Without using a pre-built physics engine, how can I implement 3-D collision detection from scratch?

    - by Andy Harglesis
    I want to tackle some basic 3-D collision detection and was wondering how engines handle this and give you a pretty interface and make it so easy ... I want to do it all myself, however. 2-D collision detection is extremely simple and can be done multiple ways that even beginner programmers could think up: 1.When the pixels touch; 2.when a rectangle range is exceeded; 3.when a pixel object is detected near another one in a pixel-based rendering engine. But 3-D is different with one dimension, but complex in many more so ... what are the general, basic understanding/examples on how 3-D collision detection can be implemented? Think two shaded, OpenGL cubes that are moved next to each other with a simple OpenGL rendering context and keyboard events.

  • redirect url ending with dot

    - by Michael
    I submitted my site's URL to my workplace's printed newsletter and when I get the printed version, they added a dot to the end of it. Some people will realize that the period is not a part of the url but others will not. Is there an easy way to redirect from http://example.com/home. to http://example.com/home? I have a IIS 7.0 shared hosting with GoDaddy. This means I have access to the box only through their interface so some options might be limited.

  • Triple monitors on hybrid video system GeForce+Intel

    - by v_mil
    I use Lenovo Ideapad Z580A with hybrid video: GeForce+Intel with Ubuntu 12.10 x64 Ukrainian. It has internal display and two outputs: HDMI and VGA. When I connect third display to VGA all displays go black. Pressing alt+backspace and login causes output to two displays: internal and VGA. System Settings - Displays (or monitors - I have Ukrainian interface) shows three displays: two are on, one (DVI) is off. Turning DVI on and pressing apply causes an error: Can not set configuration of controller CRTC 65. BIOS setting is Optimus (two video cards). Driver for GeForce is Nouveau. With best regards. Viktor.

  • xUnit global setup / teardown [migrated]

    - by Codism
    I need to run some code before any test is executed and also some code after all tests are done. I thought there must be some attributes or marker interface to indicate the global initialization and termination code but couldn't find them. Alternatively, if I can invoke xUnit programmatically, I can also achieve what I want to do by the following code: ... Main(string[] args) { try { MyGlobalSetup(); RunAllTests(); // What goes into this method? } finally { MyGlobalTeardown(); } } Can anyone provide me some hint about how to declaratively or programmally run some global setup/teardown code? Thanks

  • 11.04 Wireless is disabled by hardware switch Hp Compaq nc6220

    - by user75711
    Here is some backstory if it is helpful: I had Windows Vista on my computer and I wanted to use wubi to install Ubuntu, everything was fine until I booted into the OS. It said my wireless was disabled by a Hardware Switch. So I booted back into Vista and it disabled there too. I have gotten rid of vista and installed 11.04 instead. It still has this error and as far as I know there is no switch anywhere and the fn keys do nothing. My lshw is: *-network DISABLED description: Wireless Interface product: PRO/Wireless 2915ABG [Calexico2] Network Connection vendor: Intel Corporation physical id: 4 bus info: pci@0000:02:04.0 logical name: eth1 version: 05 serial: 00:15:00:0c:5d:62 width: 32 bits clock: 33MHz capabilities: pm bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver-ipw2200 driverversion=1.2.2kmprq firmware=ABG:9.0.5.27 (Dec 12 2007) latency=64 link=no maxlatency=24 mingnt=3 multicast=yes wireless=IEEE 802.11abg resources: irq:21 memory:d0400000-d0400fff Thanks

  • Progressing past CRUD applications in PHP?

    - by Anonymous -
    I've been programming in PHP for about a year and am at the following stage: Have a good 'feel' for the language Can create CRUD applications competently Can utilize an MVC structure to allow for future expansion of code Using the points listed above, I've created a number of my own applications for practise - including but not limited to; a forum, social network etc. My question may be a little vague but should hopefully be answerable. I feel as though there isn't anything else I would need to know about PHP to allow me to create websites, though I'm sure I'm wrong. What advanced/complex PHP topics could I look at that have a real-world use and will allow me to enhance both my skill as a programmer and applications in general? Recently I've looked a lot more at javascript/jQuery allowing me to give my applications a richer user interface which has been a great learning experience and proving very useful.

  • Dell Latitude D830 DVD Drive Not Recognized

    - by DragonFire
    Unlike some people who have issues with the video or WiFi drivers, I suffer from not being able to use the DVD drive on this laptop. Upon POST, the BIOS sees it and I am able to open the tray as well; however, once the system starts to load up Ubuntu or other distros (Debian and Linux Mint), I lose all functionality. Plus, I don't see it listed as a device in the OS. I've poured over the internet the past few days trying to see if anyone else has the issue, or did and found a solution but sadly, nothing anywhere so far. So, I thought I would ask the community here and see what you all think. Worse case scenario, I have some dead weight to a nice little machine. Thanks! PS I honestly think Linux doesn't like the IDE interface the disc drive has.

  • How to get BURG on 12.10 (Quantal Quetzal)

    - by Warpspace
    I've been using BURG for years to get rid of the eye sore that is the standard GRUB interface. When I upgraded to Quantal, the repository does not contain the updated information. I.e. after I add sudo add-apt-repository ppa:n-muench/burg sudo apt-get update I get the annoying response W: Failed to fetch http://ppa.launchpad.net/n-muench/burg/ubuntu/dists/quantal/main/binary-amd64/Packages 404 Not Found It's been like this for a month, contrary to various websites which say it works. Is BURG being maintained? Have they created a better alternative (such as integration with GRUB, like it should have been in the first place). How do I get a decent-looking bootloader?

  • Installing multi-boot Linux system

    - by user94924
    I have a dual (XP/Linux) boot Compaq Presario S4500UK with a couple of spare partitions on the boot drive which I want to use for testing different Linux distros/configs before installing them on "live" machines. I tried this with Oneiric which worked fine until I came to uninstalling the test system. Fortunately Oneiric uses Grub2 and so redirecting the bootloader to work from the original Linux partition was a piece of cake - if a bit annoying. I now need to do some tests on Hardy and DSL (Damned Small Linux), neither of which use Grub2. Question: Is it possible to install a test operating system without adding/replacing the bootloader (ie so I can still use Grub2 from the original partition with its nice interface and recovery facilities)? Is there another way of uninstalling/decommisioning a test OS which doesn't trash the boot loader? (The only way I know to do this is by deleting/reformatting the partition which takes with it the bootloader which is in that partition). Any help would be much appreciated. Tks jg1

  • Instantiating Interfaces in C#?

    - by RealityDysfunction
    I am reading/learning about interfaces in C# at the moment, and thus far I managed to understand how it differs from an abstract class. In the book I am reading the author explains that interfaces are the ultimate abstract class and that it simply sets the standard of certain methods the inheriting class will have, but then provides the following example... static void Main(string[] args) { ... Circle c = new Circle("Lisa"); IPointy itPt = null; try { itPt = (IPointy)c; Console.WriteLine.(itPt.Points); } catch (InvalidCastException e) { Console.WriteLine(e.Message); } ... } The line that absolutely throws me off is the "IPointy itfPt=null;" did he just declare an interface??? I thought interfaces are abstract and can only be inherited? What kind of sorcery is going on here? Thanks for any help, I

  • 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.
