• Steps to manage a large project [closed]

  - by l46kok

  Software development is an area where parallel development to its fullest form is very difficult to achieve, although you could get reasonably close with the right design. This is especially true for game development. That being said, if you are designing a game from scratch from engine to front end, what steps should be taken in order? How would you efficiently manage your project and your team? I'm asking because several people and I are interested in working on a relatively large project for learning purposes. Initially, we were going to use a proprietary engine like Unity, but since we wanted to learn how the engine works, we're going to start from bottom. I'd appreciate any suggestions that you guys can provide me.

• Book Review: Silverlight 4 Business Application Development

  I normally don't do book reviews here but this book is kind of cool and what I'm looking for. Silverlight 4 Business Application Development, here is a book that is kind of not so much on the UX side but what stands out about this book is the fact that it is more pictures and code then text especially when compared to a regular book.

• i5 540M or i7 720QM for laptop running VMs and software development tools?

  - by Donald Hughes

  I'm a software developer that would primarily be running Windows 7 as the primary operating system. On a typical day, I might, at any given moment, be running Visual Studio, Expression Web, SQL Server developer (and Management Console), IIS, Photoshop, a dozen browser tabs in 2-3 different browsers, Skype video chat, streaming music, and a couple of VMs (WinXP and Ubuntu) for testing/experimentation. Obviously, RAM is a concern, which is why I plan to use 8 GB so I can devote enough to the VMs to be usable. I'm also tempted to use an ExpressCard SSD for storing the VM disks to ease disk contention. And I know that that is asking a lot from a laptop, and I should just use a desktop, but I need to be able to take my work with me between several locations. It seems that at a reasonable price point, it comes down to the i5 540M versus the i7 720QM. I'm leaning toward the i7 since it would allow me to dedicate a whole hyperthreaded core to each VM, and still have two cores left for the primary OS. I've heard that the i5 has better battery life, but I'm curious for my scenario if there would be a meaningful difference. I don't usually work without a plug, but I do occasionally ride the train or fly and it would be nice to have at least 3 hours of juice for unusual circumstances. And, finally, for this usage scenario, would a dedicated video option be preferred over the i5's integrated video? It sounds like Visual Studio 2010 (and Windows 7) can take advantage of the video card.

• Sharing VPN from XP to Linux virtual

  - by user55513

  Hi I will keep the question simple with few details, if more is needed tell me. Thanks. I am playing around with networking and virtualbox. So I have 2 virtual machines. One is windows xp and another has linux in it. Windows XP has 2 network cards. One for the internet and the other to connect to the linux computer. Linux has one 1 card and it can only access the internet passing through Windows XP. Internet works fine until I activate OpenVPN on Windows. When I turn on VPN, Linux has no access to it. How can I make linux use VPN too? I believe it has something to do with using the "route" command on XP to send VPN traffic to Linux but I was not able to figure it out how yet.

• Web Development - How to access custom host, defined in my hosts file, from another device in the same network

  - by Neara

  Ok, I hope i'll be able to explain the issue im experiencing. I'm working on a project, that has 2 parts: one takes all requests from usual localhost, the other handles requests from myhost.local. While trying to access both addresses from my computer, it works ok. But now i need to test myhost.local on mobile devices, connected to the same network. Usually i would just run server from my computer ip in the network: python manage.py runserver 10.0.0.8:8000 And then from any device, going to 10.0.0.8:8000 would show the project im working on. However, now accessing that ip address routes me straight to localhost. So, my question is how to access myhost.local from another device in same network? I don't want to change router settings, if that can be avoided, cos sometimes i work from places where i can't access router admin. Is there any network settings on my computer, that i can change to fix the routing to myhost.local w.o losing access to localhost as well?

• Install Ubuntu Netbook Edition with Wubi Installer

  - by Matthew Guay

  Ubuntu is one of the most popular versions of Linux, and their Netbook Remix edition is especially attractive for netbook owners.  Here we’ll look at how you can easily try out Ubuntu on your netbook without a CD/DVD drive. Netbooks, along with the growing number of thin, full powered laptops, lack a CD/DVD drive.  Installing software isn’t much of a problem since most programs, whether free or for-pay, are available for download.  Operating systems, however, are usually installed from a disk.  You can easily install Windows 7 from a flash drive with our tutorial, but installing Ubuntu from a USB flash drive is more complicated.  However, using Wubi, a Windows installer for Ubuntu, you can easily install it directly on your netbook and even uninstall it with only a few clicks. Getting Started Download and run the Wubi installer for Ubuntu (link below).  In the installer, select the drive you where you wish to install Ubuntu, the size of the installation (this is the amount dedicated to Ubuntu; under 20Gb should be fine), language, username, and desired password.  Also, from the Desktop environment menu, select Ubuntu Netbook to install the netbook edition.  Click Install when your settings are correct. Wubi will automatically download the selected version of Ubuntu and install it on your computer. Windows Firewall may ask if you want to unblock Wubi; select your network and click Allow access. The download will take around an hour on broadband, depending on your internet connection speed.  Once the download is completed, it will automatically install to your computer.  If you’d prefer to have everything downloaded before you start the install, download the ISO of Ubuntu Netbook edition (link below) and save it in the same folder as Wubi. Then, when you run Wubi, select the netbook edition as before and click Install.  Wubi will verify that your download is valid, and will then proceed to install from the downloaded ISO.  This install will only take about 10 minutes. Once the install is finished you will be asked to reboot your computer.  Save anything else you’re working on, and then reboot to finish setting up Ubuntu on your netbook. When your computer reboots, select Ubuntu at the boot screen.  Wubi leaves the default OS as Windows 7, so if you don’t select anything it will boot into Windows 7 after a few seconds. Ubuntu will automatically finish the install when you boot into it the first time.  This took about 12 minutes in our test. When the setup is finished, your netbook will reboot one more time.  Remember again to select Ubuntu at the boot screen.  You’ll then see a second boot screen; press your Enter key to select the default.   Ubuntu only took less than a minute to boot in our test.  When you see the login screen, select your name and enter your password you setup in Wubi.  Now you’re ready to start exploring Ubuntu Netbook Remix. Using Ubuntu Netbook Remix Ubuntu Netbook Remix offers a simple, full-screen interface to take the best advantage of netbooks’ small screens.  Pre-installed applications are displayed in the application launcher, and are organized by category.  Click once to open an application. The first screen on the application launcher shows your favorite programs.  If you’d like to add another application to the favorites pane, click the plus sign beside its icon. Your files from Windows are still accessible from Ubuntu Netbook Remix.  From the home screen, select Files & Folders on the left menu, and then click the icon that says something like 100GB Filesystem under the Volumes section. Now you’ll be able to see all of your files from Windows.  Your user files such as documents, music, and pictures should be located in Documents and Settings in a folder with your user name. You can also easily install a variety of free applications via the Software Installer. Connecting to the internet is also easy, as Ubuntu Netbook Remix automatically recognized the WiFi adaptor on our test netbook, a Samsung N150.  To connect to a wireless network, click the wireless icon on the top right of the screen and select the network’s name from the list. And, if you’d like to customize your screen, right-click on the application launcher and select Change desktop background. Choose a background picture you’d like. Now you’ll see it through your application launcher.  Nice! Most applications are opened full-screen.  You can close them by clicking the x on the right of the program’s name. You can also switch to other applications from their icons on the top left.  Open the home screen by clicking the Ubuntu logo in the far left. Changing Boot Options By default, Wubi will leave Windows as the default operating system, and will give you 10 seconds at boot to choose to boot into Ubuntu.  To change this, boot into Windows and enter Advanced system settings in your start menu search. In this dialog, click Settings under Startup and Recovery. From this dialog, you can select the default operating system and the time to display list of operating systems.  You can enter a lower number to make the boot screen appear for less time. And if you’d rather make Ubuntu the default operating system, select it from the drop-down list.   Uninstalling Ubuntu Netbook Remix If you decide you don’t want to keep Ubuntu Netbook Remix on your computer, you can uninstall it just like you uninstall any normal application.  Boot your computer into Windows, open Control Panel, click Uninstall a Program, and enter ubuntu in the search box.  Select it, and click Uninstall. Click Uninstall at the prompt.  Ubuntu uninstalls very quickly, and removes the entry from the bootloader as well, so your computer is just like it was before you installed it.   Conclusion Ubuntu Netbook Remix offers an attractive Linux interface for netbooks.  We enjoyed trying it out, and found it much more user-friendly than most Linux distros.  And with the Wubi installer, you can install it risk-free and try it out on your netbook.  Or, if you’d like to try out another alternate netbook operating system, check out our article on Jolicloud, another new OS for netbooks.

• How to debug a native Java crash on Linux?

  - by Paul J. Lucas

  I've seen this question and this article on how to debug a native Java crash. The article is with respect to Windows. What are the equivalent debugging aids on Linux? Note: All I have is this crash log from a user in the field. I do not have access to the machine on which the crash occurred. Update: I am pretty sure the crash is due to JNI code we have.

• Are there any prototype-based languages with a whole development cycle?

  - by Kaveh Shahbazian

  Are there any real-world prototype-based programming languages with a whole development cycle? "A whole development cycle" like Ruby and Python: web frameworks, scripting/interacting with the system, tools for debugging, profiling, etc. Thank you A brief note on PBPLs: (let's call these languages PBPL : prototype-based programming language) There are some PBPLs out there. Some are being widely used like JavaScript (which Node.js may bring it into the field - or may not!). One other language is ActionScript which is also a PBPL but tightly bound to Flash VM (is it correct to say so?). From less known ones I can speak of Lua which has a strong reputation in game development (mostly spread by WOW) but never took off as a full language. Lua has a table concept which can provide you some sort of prototype based programming facility. There is also JScript (Windows scripting tool) which is already pointless by the newcomer PowerShell (I have used JScript to manipulate IIS but I never understood what is JScript!). Others can be named like io (indeed very very neat, you will fall in love with it; absolutely impossible to use) and REBOL (What is this all about? A proprietary scripting tool? You must be kidding!) and newLISP (Which is actually a full language, but no one ever heard about it). For sure there are much more to list here but either I do not remember or I did not understood them as a real world thing, like Self).

• How to loop an executable command in the terminal in Linux?

  - by user1452373

  Let me first describe my situation, I am working on a Linux platform and have a collection of .bmp files that add one to the picture number from filename0022.bmp up to filename0680.bmp. So a total of 658 pictures. I want to be able to run each of these pictures through a .exe file that operates on the picture then kicks out the file to a file specified by the user, it also has some threshold arguments: lower, upper. So the typical call for the executable is: ./filter inputfile outputfile lower upper Is there a way that I can loop this call over all the files just from the terminal or by creating some kind of bash script? My problem is similar to this: Execute a command over multiple files with a batch file but this time I am working in a Linux command line terminal. Thank you for your help, Luke H

• How to make an ISO copy of Linux-filesystem and user files of VPS Debian based?

  - by moogeek

  Hello! I have a Debian-Based VPS on some hosting. I want to migrate from it and i need to make a full copy of all Linux-filesystem (and installed packages) + all home directory with website files. And then pack/convert it to ISO image so that to use it on cloud hostings like Amazon. The problem is that i have only ssh root access. Hosting support can't do that for me. Another part of the question - is it possible to enlarge the Linux-filesystem by not re-installing it and using the free space of home directory? Is it possible to do? I guess it is possible with rsync or something like that. Will my Mysql databes copy together with all other data? Thanks in advance!

• Linux: How to find all serial devices (ttyS, ttyUSB, ..) without opening them?

  - by Thomas Tempelmann

  What is the proper way to get a list of all available serial ports/devices on a Linux system? In other words, when I iterate over all devices in /dev/, how do I tell which ones are serial ports in the classic way, i.e. those usually supporting baud rates and RTS/CTS flow control? The solution would be coded in C. I ask because I am using a 3rd party library that does this clearly wrong: It appears to only iterate over /dev/ttyS*. The problem is that there are, for instance, serial ports over USB (provided by USB-RS232 adapters), and those are listed under /dev/ttyUSB*. And reading the Serial-HOWTO at Linux.org, I get the idea that there'll be other name spaces as well, as time comes. So I need to find the official way to detect serial devices. Problem is that there appears none documented, or I can't find it. I imagine one way would be to open all files from /dev/tty* and call a specific ioctl() on them that is only available on serial devices. Would that be a good solution, though? Update hrickards suggested to look at the source for "setserial". Its code does exactly what I had in mind: First, it opens a device with: fd = open (path, O_RDWR | O_NONBLOCK) Then it invokes: ioctl (fd, TIOCGSERIAL, &serinfo) If that call returns no error, then it's a serial dev, apparently. I found similar code here, which suggested to also add the O_NOCTTY option. There is one problem with this approach, though: When I tested this code on BSD Unix (i.e. OSX), it worked as well, however serial devices that are provided thru Bluetooth cause the system (driver) to try to connect to the bluetooth device, which takes a while before it'll return with a timeout error. This is caused by just opening the device. And I can imagine that similar things can happen on Linux as well - ideally, I should not need to open the device to figure out its type. I wonder if there's also a way to invoke ioctl functions without an open, or open a device in a way that it does not cause connections to be made? Any ideas?

• Linux, how to capture screen, and simulate mouse movements.

  - by 2di

  Hi All I need to capture screen (as print screen) in the way so I can access pixel color data, to do some image recognition, after that I will need to generate mouse events on the screen such as left click, drag and drop (moving mouse while button is pressed, and then release it). Once its done, image will be deleted. Note: I need to capture whole screen everything that user can see, and I need to simulate clicks outside window of my program (if it makes any difference) Spec: Linux ubuntu Language: C++ Performance is not very important,"print screen" function will be executed once every ~10 sec. Duration of the process can be up to 24 hours so method needs to be stable and memory leaks free (as usuall :) I was able to do in windows with win GDI and some windows events, but I'ev no idea how to do it in Linux. Thanks a lot

• Linux - How do i know the block map of the given file and/or the free space map of the partition.

  - by Inso Reiges

  Hello, I am on Linux and need to know either of the two things: 1) If i have a regular file on some file system on a partition under Linux is there a way to know the set of the physical blocks that this file occupies on the drive from user space? Or at least the set of the file system's clusters? 2) Is there a way to get the same information about the whole free space of the given file system? In both cases i understand that if there is any possible way to extract this info it will probably be totally unsafe and racy (anything could happen to these set of blocks between the time i see them and act on them somehow). I also really don't want an implementation that will have to know a lot about every filesystem.

• Having trouble reading XML file from Windows server. Works on Linux

  - by DuFF14

  I'm parsing an XML file in an android app. My success varies depending upon where the file is hosted. After hosting the file on 4 different servers (2 Linux, 2 Windows), I discovered that when the xml is hosted on a Linux server, the app works. When it's hosted on a Windows server, I am unable to parse correctly. Instead of reading the expected xml tags, it reads HTML tags (, , , etc). I'm not sure why it doesn't work on Windows servers, or if that is even the issue and not just a coincidence. Any help is appreciated. Thanks. Here is my code: private void getXmlData() { HttpClient httpclient = new DefaultHttpClient(); String url = XML_URL; HttpPost httppost = new HttpPost(url); HttpResponse response = httpclient.execute(httppost); SaxParser saxParser = new SaxParser(response); parsedXML = saxParser.parse(); }

• What single software development tool do you think holds the most value?

  - by Phobis

  Every day I realize how much I love Visual Studio for .NET development.... but, I believe that Resharper, may hold a value that surpasses Visual Studio's (I am using VS 2005 for WPF/WCF development). I decided it would be great to compile a list of the most valuable tools for software development. These can be applications/plug-ins anything that you think holds GREAT value. Also, please explain the benefits of the tool that you are posting. Resharper: Intergrated Unit testing "Camel Hump" code auto completion Find "usings" (inverse of "Go to Deceleration") Code formating and member rearranging Assembly and namespace inclusion (based on your code) Check for common optimizations and possible bugs in code and suggests/rewrites the code for you (things like null checking, redundant delegate creation, inverting if statements, etc...); Tells you when code and be more generic (may suggest things like "use this interface instead" if your code never refers to something specific on an object) Helps you see code that is not being used and will clean any unused members. File structure view helps you jump around the regions of your file (this is really awesome and clean). Class searching (you can use things like camel humps) Asks you which partial file to open once you find a class. It also has it's own plugin support, so you can do things like FxCop, documentation and relfector (all free). This thing has so much I don't think I hit 10% of it yet :) [When I get time, I will try to add more... feel free to help me out]
