  • On Windows 7, how to check that applications are in the correct Program Files directory?

    - by Anon Guy
    In Windows 7, applications should be installed to "Program Files" or "Program Files (x86)" depending on whether they are 64-bit or 32-bit (respectively, as per this page). Is there an easy way to check that all the applications on my system are in the correct Program Files directory? To put it another way, is an easy way to detect any 32-bit applications in "Program Files" and 64-bit applications in "Program Files (x86)"?

  • What's a good open source java project for students to hack on?

    - by Evan Grim
    I'm working with a professor to develop a course teaching practical software development tools and methodology. We're looking for a sample code base that we can use for hands-on experience in each of the topics and as the basis for a semester-long project where students will work in a team to implement a feature or fix bugs. Here are some basic guidelines for the project that we'd like to come close to meeting: java based, ~50K SLOC, uses ant, depends upon some external library, has a test suite (preferably jUnit), friendly for development within eclipse, actively developed with a substantial history available within a version control system (such as subversion), the more "coolness" factor the better (to motivate the students), and preferably with some kind of user interface (e.g.: not just a library).

  • Move Files from a Failing PC with an Ubuntu Live CD

    - by Trevor Bekolay
    You’ve loaded the Ubuntu Live CD to salvage files from a failing system, but where do you store the recovered files? We’ll show you how to store them on external drives, drives on the same PC, a Windows home network, and other locations. We’ve shown you how to recover data like a forensics expert, but you can’t store recovered files back on your failed hard drive! There are lots of ways to transfer the files you access from an Ubuntu Live CD to a place that a stable Windows machine can access them. We’ll go through several methods, starting each section from the Ubuntu desktop – if you don’t yet have an Ubuntu Live CD, follow our guide to creating a bootable USB flash drive, and then our instructions for booting into Ubuntu. If your BIOS doesn’t let you boot using a USB flash drive, don’t worry, we’ve got you covered! Use a Healthy Hard Drive If your computer has more than one hard drive, or your hard drive is healthy and you’re in Ubuntu for non-recovery reasons, then accessing your hard drive is easy as pie, even if the hard drive is formatted for Windows. To access a hard drive, it must first be mounted. To mount a healthy hard drive, you just have to select it from the Places menu at the top-left of the screen. You will have to identify your hard drive by its size. Clicking on the appropriate hard drive mounts it, and opens it in a file browser. You can now move files to this hard drive by drag-and-drop or copy-and-paste, both of which are done the same way they’re done in Windows. Once a hard drive, or other external storage device, is mounted, it will show up in the /media directory. To see a list of currently mounted storage devices, navigate to /media by clicking on File System in a File Browser window, and then double-clicking on the media folder. Right now, our media folder contains links to the hard drive, which Ubuntu has assigned a terribly uninformative label, and the PLoP Boot Manager CD that is currently in the CD-ROM drive. Connect a USB Hard Drive or Flash Drive An external USB hard drive gives you the advantage of portability, and is still large enough to store an entire hard disk dump, if need be. Flash drives are also very quick and easy to connect, though they are limited in how much they can store. When you plug a USB hard drive or flash drive in, Ubuntu should automatically detect it and mount it. It may even open it in a File Browser automatically. Since it’s been mounted, you will also see it show up on the desktop, and in the /media folder. Once it’s been mounted, you can access it and store files on it like you would any other folder in Ubuntu. If, for whatever reason, it doesn’t mount automatically, click on Places in the top-left of your screen and select your USB device. If it does not show up in the Places list, then you may need to format your USB drive. To properly remove the USB drive when you’re done moving files, right click on the desktop icon or the folder in /media and select Safely Remove Drive. If you’re not given that option, then Eject or Unmount will effectively do the same thing. Connect to a Windows PC on your Local Network If you have another PC or a laptop connected through the same router (wired or wireless) then you can transfer files over the network relatively quickly. To do this, we will share one or more folders from the machine booted up with the Ubuntu Live CD over the network, letting our Windows PC grab the files contained in that folder. As an example, we’re going to share a folder on the desktop called ToShare. Right-click on the folder you want to share, and click Sharing Options. A Folder Sharing window will pop up. Check the box labeled Share this folder. A window will pop up about the sharing service. Click the Install service button. Some files will be downloaded, and then installed. When they’re done installing, you’ll be appropriately notified. You will be prompted to restart your session. Don’t worry, this won’t actually log you out, so go ahead and press the Restart session button. The Folder Sharing window returns, with Share this folder now checked. Edit the Share name if you’d like, and add checkmarks in the two checkboxes below the text fields. Click Create Share. Nautilus will ask your permission to add some permissions to the folder you want to share. Allow it to Add the permissions automatically. The folder is now shared, as evidenced by the new arrows above the folder’s icon. At this point, you are done with the Ubuntu machine. Head to your Windows PC, and open up Windows Explorer. Click on Network in the list on the left, and you should see a machine called UBUNTU in the right pane. Note: This example is shown in Windows 7; the same steps should work for Windows XP and Vista, but we have not tested them. Double-click on UBUNTU, and you will see the folder you shared earlier! As well as any other folders you’ve shared from Ubuntu. Double click on the folder you want to access, and from there, you can move the files from the machine booted with Ubuntu to your Windows PC. Upload to an Online Service There are many services online that will allow you to upload files, either temporarily or permanently. As long as you aren’t transferring an entire hard drive, these services should allow you to transfer your important files from the Ubuntu environment to any other machine with Internet access. We recommend compressing the files that you want to move, both to save a little bit of bandwidth, and to save time clicking on files, as uploading a single file will be much less work than a ton of little files. To compress one or more files or folders, select them, and then right-click on one of the members of the group. Click Compress…. Give the compressed file a suitable name, and then select a compression format. We’re using .zip because we can open it anywhere, and the compression rate is acceptable. Click Create and the compressed file will show up in the location selected in the Compress window. Dropbox If you have a Dropbox account, then you can easily upload files from the Ubuntu environment to Dropbox. There is no explicit limit on the size of file that can be uploaded to Dropbox, though a free account begins with a total limit of 2 GB of files in total. Access your account through Firefox, which can be opened by clicking on the Firefox logo to the right of the System menu at the top of the screen. Once into your account, press the Upload button on top of the main file list. Because Flash is not installed in the Live CD environment, you will have to switch to the basic uploader. Click Browse…find your compressed file, and then click Upload file. Depending on the size of the file, this could take some time. However, once the file has been uploaded, it should show up on any computer connected through Dropbox in a matter of minutes. Google Docs Google Docs allows the upload of any type of file – making it an ideal place to upload files that we want to access from another computer. While your total allocation of space varies (mine is around 7.5 GB), there is a per-file maximum of 1 GB. Log into Google Docs, and click on the Upload button at the top left of the page. Click Select files to upload and select your compressed file. For safety’s sake, uncheck the checkbox concerning converting files to Google Docs format, and then click Start upload. Go Online – Through FTP If you have access to an FTP server – perhaps through your web hosting company, or you’ve set up an FTP server on a different machine – you can easily access the FTP server in Ubuntu and transfer files. Just make sure you don’t go over your quota if you have one. You will need to know the address of the FTP server, as well as the login information. Click on Places > Connect to Server… Choose the FTP (with login) Service type, and fill in your information. Adding a bookmark is optional, but recommended. You will be asked for your password. You can choose to remember it until you logout, or indefinitely. You can now browse your FTP server just like any other folder. Drop files into the FTP server and you can retrieve them from any computer with an Internet connection and an FTP client. Conclusion While at first the Ubuntu Live CD environment may seem claustrophobic, it has a wealth of options for connecting to peripheral devices, local computers, and machines on the Internet – and this article has only scratched the surface. Whatever the storage medium, Ubuntu’s got an interface for it!

  • How to incorporate existing open source software from a licensing perspective?

    - by Matt
    I'm working on software that uses the following libraries: Biopython SciPy NumPy All of the above have licenses similar to MIT or BSD. Three scenarios: First, if I don't redistribute those dependencies, and only my code, then all I need is my own copyright and license (planing on using the MIT License) for my code. Correct? What if I use py2exe or py2app to create a binary executable to distribute so as to make it easy for people to run the application without needing to install python and all the dependencies. Of course this also means that my binary file(s) contains python itself (along with any other packages I might have performed a pip install xyz). What if I bundle Biopython, SciPy, and NumPy binaries in my package? In the latter two cases, what do I need to do to comply with copyright laws.

  • Is there an open-source project that can be an example of well-written code?

    - by Renato Dinhani Conceição
    The title express my intention. I want to see the code of a big project that can be considered a good example of good code writing (clean code, modularization, comments, etc.) I don't want to know if the tool is good or not, but only how the code IS. There is some project that can be used as example? I'm asking this because must great projects have their flaws, some pieces or entire code that appears to be writing to a new person presented to system development (I think that maybe everyone do this in some part of their projects).

  • What is the basic loadout for an open source web developer?

    - by DeveloperDon
    Thus far, I have mainly been an embedded developer, but I am interested in having the flexibility to do mobile and web development as well. I think my tools should include the following, but probably a lot more. LAMP stack. Java IDEs like Eclipse and IntelliJ. JS frameworks like Dojo, Node.JS, AngularJS, (is it better to mix or commit to one?). Cloud solutions like EC2 and Azure (again, ok to mix or better to commit to one?). Google APIs. Continuous integration server. Source control tools with Git for new work, SVN, CVS, +others for imports. FTP server. Unit test runners. Bug trackers. OOAD modeling tools or plug-ins? Graphic design tools? Hosting services. XML / JSON / other markup? Content management, SEO? I am also interested to know if there are tools where it might be better to mix, match, or support all available (maybe for source control) and others where the full focus should be on one (maybe Java vs. C# or Windows vs. Linux vs. MacOS). Perhaps some of these questions need context of whether the projects will be greenfield (just pick favorite) or maintenance (no choice, each project continues legacy, sometimes with a poor tools).

  • Has an open console any chance to give more strength to the indie game world ?

    - by jokoon
    I have heard about the GPX, but i don't really think the embedded market is mature enough in terms of performance, but what about the home console market ? I'm not talking about last-generation graphics, because that would be economically impossible, but what about an hardware as fast as a playstation 2/Xbox 1/Gamecube ? For games, the trick would be to ask some editors to recompile their best sellers for the new machine: those games being from the PSX age or even older console generations, I think this would have a very low cost job and they could still make some good profit, but I need to know if this is doable technically, considering the architecture which can be quite exotic. Do you think it would be a viable project to talk about to investors ?

  • Is there a term for quasi-open source proprietary software?

    - by mwhite
    Say a company wants to keep development of new features of a piece of software internal, but wants to make the source code for previous versions public, up to and including existing public features, so that other people can benefit from using and modifying the software themselves, and even possibly contribute changes that can be applied to the development branch. Is there a term for this sort of arrangement, and what is the best way of accomplishing it using existing version control tools and platforms?

  • Is there an (open-source) ReST-based blogging/forum package out there?

    - by Malvolio
    The site I work on is almost entirely in Javascript, it just goes back (via Ajax) to the server for authentication, database access, things like that. My boss would like me to add blogging, forum, and commenting capabilities. I don't want to implement it from scratch and I certainly don't want to integrate some HTML-generating PHP atrocity. Ideal, I'm looking for a package that does all the backend work and offers ReST interface so I can write a Javascript-based UI that integrates nicely with the existing site. Does such a thing exist?

  • Open Source HTML/JS game(s) with license that would allow embedding in my app?

    - by DustMason
    I'm working on an educational app for kids. At the end of the sign-up process, the kids must wait for a confirmation from their parents in order to gain access to the app. While they wait for this to happen, we want to let the kid play a simple game as a way to keep their interest up. Is there a marketplace or repository for games with such a license that we could either purchase (affordably) or use for free in our own app?

  • What steps should be taken to ensure that an open source database gets ready for production?

    - by I_like_traffic_lights
    I am considering using GridSQL in a production environment. However, I do have some indications that it is not ready. One is that it got excluded by the offering of EnterpriseDB a while ago, and the forums seem to report a few wrong results and relatively severe bugs. The alternatives to GridSQL, however cost around 100.000$ to buy, so I was thinking to utilize some of this money to ensure that GridSQL gets ready for production. At the same time, I could risk spending 50.000$ and months of work on the development of GridSQL, just to discover that the design was flawed and that a complete rewrite is needed. Then I would have to buy the commercial alternatives to GridSQL and the existence of my startup would be at risk. Question What steps would you take to ensure that there is as little risk as possible that the worst case scenario described above would happen? It is unrealistic that I could do much testing nor code review/coding myself (I am also not the best developer), so please describe where to find the guys that would need to do the work.

  • How to deal with well-meaning open-source contributors?

    - by Solo
    If a programmer contacts you and asks to contribute to your project, how do you handle it? You don't know if this guy is any good. Perhaps he'll be more trouble than he's worth. He might be trying to attach his name to a successful project just for the kudos. He might be trying to take the project in a direction you don't really want, adding features you think aren't worth the extra complexity. Or, he might be a very useful contributor. You just don't know. How do you handle such requests from people you don't know (On GitHub, specifically, if that makes any difference)? What's the etiquette here?

  • Open Source Web Frameworks : Security

    - by trappedIntoCode
    How secure are popular open source web frameworks? I am particularly interested in popular frameworks like Rails and DJango. If I am building a site which is going to do heavy e-commerce, is it Ok to use frameworks like DJango and Satchmo? Is security compromised because their open architecture ? I know being OS does not mean being down right open to hackers, Linux uses superb authentication mechanism, but web is a different game. What can be done in this regard? UPDATE: Thanks for answers guys. I understand that I will have to find a suitable hosting service for a secure e-commerce application and that additional layers of security will be needed. I understand that Django and Rails have been designed keeping security aspects in mind, the most common form attacks like XSS, Injections etc. (Django book has a ch on Security) I was expecting comments from security Gurus. If you are a security Guru, would you recommend an important site, which is likely going to be popular, to be built on DJango or Rails?

  • Open Source CMS (.Net vs Java)

    - by CmsAndDotNetKindaGuy
    I must say up-front that this is not a strictly programming-related question and a very opinionated one. I am the lead developer of the dominant .Net CMS in my country and I don't like my own product :). Managerial decisions over what is important or not and large chunks of legacy code done before I joined gives me headache every day I go for work. Anyway, having a vast amount of experience in web industry and a very good grasp of C# and programming practices I'm designing my own CMS the past few months. Now the problem is that I'm an open source kinda guy so I have a dilemma. Should I use C# and .Net which has crippled multi-platform support or should I drop .Net entirely and start learning Java where I can create a truly open-source and cross-platform CMS? Please don't answer that I should contribute to an existing open source CMS. I ruled that out after spending a great deal of time searching for something similar in structure to what I have in mind. I am not a native speaker, so feel free to correct my syntax or rephrase my question.

  • How to compile Open Flash Chart v.1?

    - by geehertush01
    Let me just say, that I'm a total beginner in anything related to flash. I would like to compile latest version of OFC1 (v.1.9.7). It can be downloaded here: link. Unfortunately no tutorial of how to do it can be found anywhere. I succeeded in compiling OFC2 (v.Lug-Wyrm-Charmer). I installed FlashDevelop, then I found .proj file in the OFC2 package, opened it in FlashDevelop and built the project. It worked fine (although I had to fix some code errors, but it was simple). Unfortunately there is no project file in OFC1 package. I tried to create a new project (Project-New Project-AS3 Project). It created .proj file and few folders (src,bin...). I deleted 'Main.as' from 'src' folder. Then I copied all files from 'actionscript' folder from OFC1 to 'src' project folder. I opened the project and set 'open-flash-char.as' as Document Class (right click on the file in the project tree and 'Set Document Class'). Then I tried to build the project, but got an syntax error with (in 'open-flash-char.as'): #include "prototype.drawCircle.as" #include "prototype.fillCircle.as" #include "String.prototype.replace.as" So I removed "#" signs. But then I got an error ...\ofc1\projtest4\src\open-flash-chart.as: Error: A file found in a source-path must have an externally visible definition. If a definition in the file is meant to be externally visible, please put the definition in a package. I have no idea of how to continue. Maybe I'm doing everything wrong, because OFC1 is written in AS2 (probably), not AS3. I don't know. So my question is: How to compile OFC v.1.9.7?

  • Does implementing a Java class under an open-source library's package name constitutes a modificatio

    - by Minyu
    Greetings, I understand that this is not the best forum for getting legal advices. But I am still wondering if anybody has some experience around this topic, or can point me to relevant resources that explain it. I have tried to search it online but could not find clear answers. Assuming I am using a Java open-source library from "somecompany", specifically its entities in the "org.somecompany.somepackage". During development, I found that I need to access some of the internals of that package that are not exposed through its public interface. So I thought maybe creating my own classes under the same "org.somecompany.somepackage" name would make that easier. My question is: does this constitutes a modification of the open-source library? The fully qualified name of my classes look like "org.somecompany.somepackage.myclass". It does seem an "extension" of the original library, even though I am not modifying the original library source or binary. I am also not adding my classes to the open-source jar files. Any advice or pointer to resources will be appreciated!

  • Ubuntu One - Files API - Cloud - More detailed info somehwere?

    - by Brian McCavour
    I am just starting on a mobile app for Ubuntu One, and I'm reviewing the info at https://one.ubuntu.com/developer/files/store_files/cloud I find the information a bit lacking though. It's a nice reference, but for someone not familiar with it, I had to goggle search to find out what a "volume" was exactly (its kind of obvious, but never hurts to know the specifics) There's also things like: GET /api/file_storage/v1/volumes Return a JSON list of Volume Representations, one for each volume. A volume is a synced folder, or the Ubuntu One folder, owned by the user. Note that all volume paths begin with ~.: ... but there's no such thing as a JSON "list". Does it mean array ? And other things... So I was wondering if here existed another page with more detailed information. Maybe some sample request / responses or something? I could just write a little proof of concept app to answer some of these questions... but I prefer not to unless I have to. Thanks

  • C# Open Source/Free Social Networking SDK

    - by Nix
    I am currently gathering some technology requirements for a site that will be a social network based. I don't want to re-invent the wheel so i am looking for some type of SDK or collection of tools that can provide me with a way of creating/managing a social network. I understand that no framework will probably fit my exact needs so I am also looking for a flexible/extendable framework. An example extension point would be allowing the user to provide sub networks, maybe a global network that could be sub classified as work and friends. Beyond that it would also be nice to somehow be able to import contacts from other networking sites (Facebook, Linked In, etc). My current technology suite will more than likely consist of the following: IIS 7.0 WCF Data Services SQL Server 2006 ASP.NET front end. So my two questions are 1) C# Open Source Social Network SDK 2) C# Open Source Social Netowrk APIs (facebook, linked in, etc) If there is any more information you may need please let me know.

    I'm not sure what the "general" name of something like this might be. I'm looking for a library that gives me a file format to store different types of binary data in an expanding single file. open source, non-GPL (LGPL ok) C interface the file format is a single file multiple files within using a POSIX-like file API (or multiple "blobs" within using some other API) file/structure editing is done in-place reliable first, performant second Examples include: the virtual drives of a virtual machine whefs HDF CDF NetCDF Problems with the above: whefs doesn't appear to be very mature, but best describes what I'm after HDF, CDF, NetCDF are usable (also very reliable and fast), but they're rather complicated and I'm not entirely convinced of their support for opaque binary "blobs" Edit: Forgot to mention, one other relevant question: http://stackoverflow.com/questions/1361560/simple-virtual-filesystem-in-c-c Another similar question: http://stackoverflow.com/questions/374417/is-there-an-open-source-alternative-to-windows-compound-files Edit: Added condition of in-place editing.

  • Save Powerpoint 2007 as Powerpoint 2003 using Open Office SDK 2.0

    - by user299592
    Is there anyway to use the Open Office SDK 2.0 to save a powerpoint presention that you created using OOXML to a Office 2003 powerpoint presentation? I know if you open a 2007 file and click Save As you have the option to save it as a Powerpoint 97 to 2003 document and I didn't know if I could do this grammatically using this SDK. The reason I am asking this question is because I need to give the user the option to save data on a website in either office 2007 or 2003 format. I much rather just use the same code to produce the document instead of having to have two code paths for powerpoint 2003 and powerpoint 2007.

  • which open source license to use for libraries depending on other libraries

    - by openCage
    I develop a couple of open source projects licensed under MPL1.1. All projects depend on a lot of other open source tools. I avoid any GPL licensed libraries for the viral nature of GPL. The licenses of the libraries my tools depend on are Apache2, LGPL2, LGPL3, CPL, BSD, JSON, MIT and some personal agreements. My applications are licensed under MPL1.1 but now I want to publish some libraries. Which license is compatible with all of the above ? comfortable for the user ? My suspicion is that MPL1.1 is not that good as a library license. I'd like the libraries to be used.
