  • Creating managed file transfer software in java

    - by Shekhar
    Hello, I have been asked to do some POC on how we can provide a software solution which will be able to manage files. Manage files means it will be able to move files from source to destination servers. The client gave us 4 page document detailing what sort of software they are looking for. They dont want to use existing commercial softwares. They want to build their own customizable software. Has anybody worked on this type of project? Please provide your inputs on how should i approach this project. The software should be platform independent and should be built in java.

  • Best language to develop medical software

    - by Grace
    I need to write medical program to manage medical practices (patient records, appointments, prescription, etc). Note that this is not for US practices so US EMRs will not work. What is the best platform to develop the software in ie. language and database? Considerations include: - Integration with the web - will need to have Doctors download updates to the software from the web. Will also post reports from the software unto webpages - The software will include a mobile application - probably for Blackberry - Cost is a big factor - need to minimize the license cost to the users - Need tight security on the program

  • Apple Mac Software Development

    - by MattMorgs
    I'm planning on developing an Apple Mac application which will collect hardware information from the host Mac and also installed software info. The hardware and software info will be collected in an encrypted XML file and then posted back to a website. The application should run as a "service" or background process on the Mac and can be configured to collect the data on a frequent basis defined by another encrypted XML config file. I've done plenty of Windows based software development but never on the Mac. Can anybody point me in the direction of any useful info on how to develop on the Mac, collect hardware and software info, export to an XML file, file encryption and packaging a compiled app to run as a service? Is either Objective C, Cocoa or Ruby a possible option? Many thanks for your help in advance!

  • What license to use for translations of open source software

    - by vividos
    I'm writing an open source software that is licensed under the GPL. Now I'm offering that other users can translate the software, starting from an english translation I made by myself. What license or range of license may be best for translation of text strings, dialogs, etc.? As GPL is a software license, I thought about a Creative Commons license. The goal is so that all translations remain free and may be updated by other translators.

  • Published software not displayed in Add/Remove Programs

    - by vikramsjn
    I just followed How to use Group Policy to remotely install software in Windows Server 2003 to try publishing a software (MSI file). I could follow all the steps, but the supposedly successfully published software does not appear on client/user machine's Add/Remove Programs. Could some help figure why this may not be working. Update: On reading this question on Experts-Exchange, tried gpresults. Output extract follows: COMPUTER SETTINGS The following GPOs were not applied because they were filtered out XADistribution Filtering: Denied (Security) Default Domain Policy Filtering: Denied (Security)

  • How are requirements determined in open source software projects?

    - by Aron Lindberg
    In corporate in-house software development it is common for requirements to be determined through a formal process resulting in the creation of a number of requirements documents. In open source software development, this often seems to be absent. Hence, my question is: how are requirements determined in open source software projects? By "determining requirements" I simply mean "figuring out what features etc. should be developed as part of a specific software".

  • What is a good one-stop-shop for understanding software licensing information?

    - by Macy Abbey
    I've learned a fair amount about the various different software licensing models and what those models mean for my own software project. However, I'd like to make sure I understand as many of them as possible for making decisions on how to license my own software and in what scenarios I can safely use software under a licensing model. Do you have a good recommendation for a book/site etc.. that has this information in one location?

  • eBay Leads Mobile Commerce

    - by David Dorf
    For the first time, more smartphones where shipped than PCs. This important milestone helps reinforce that retailers need a strong mobile commerce strategy. IDC reported that for the 4th quarter of 2010, manufacturers shipped 100.9 million devices versus 92.1 million PCs shipped. One early adopter for the retail industry is eBay, the popular online auction and shopping site. In July 2008 they released their first mobile app and have increased investments ever since. In 2002 they bought PayPal for use with its online channel, but its becoming a force in the mobile world as well. In June 2010 they acquired RedLaser, the popular barcode scanning mobile app. Both pieces of technology enhance the mobile experience, and are available to other retailers as well. More recently, in December 2010 they acquired Critical Path Software, the developer of their eBay, StubHub, and Shopping.com mobile applications. Taking their mobile development in-house was a clear signal that mobile commerce is important to their strategy. Pop on over the eBay Inc's mobile commerce stats page to see just how well they are doing. You can use the animated map to see where people are using the app on any given day, and you can compare sales of the different categories. eBay's hottest category is Cars & Trucks, garnering 16.5% of the total $2B (yes, billion) in mobile sales in 2010. To understand why that category is so large, let's look at the top 10 most expensive cars sold on eBay mobile in 2010: $240,001 Mercedes-Benz: SLR McLaren $209,888 Lamborghini: Gallardo $208,500 Ferrari: 430 $199,900 Lamborghini: Gallardo $189,000 Lamborghini: Murcielago $185,000 Ferrari: 430 $175,000 Porsche: 911 $170,000 Ferrari: 550 $160,000 Bentley: Continental, GT $159,900 Lamborghini: Gallardo eBay claims they sell 3-4 Ferraris on their mobile app each month. Yes, mobile commerce is not limited to small items. While I would wait to get home and fire up the PC, the current generation that has grown up with mobile phones has no issue satisfying their impulses. Dave Sikora of Digby told me he's seen people buy furniture sets, mattresses, and diamonds via their mobile phones. I guess mobile commerce is rapidly becoming the norm.

  • "Oracle", "Sybase", "SQL Server" vs just "SQL/JDBC" in the CV

    - by bobah
    How would you define a testable measure of the expertise that, if you're honest with yourself, lets you write in your CV words "Oracle", "Sybase", or "SQL Server" and not just "Relational Databases, SQL, JDBC" in your software developer's CV? What every XXX-developer (XXX - a vendor name) should know? The question is similar to http://stackoverflow.com/questions/2119859/questions-every-good-database-sql-developer-should-be-able-to-answer but is vendor-specific. Below is a start of the list as an example, demonstrate what kind of answers I am hoping to get. If you are expert in X then you know that Y (X - Y below): Sybase/SQL Server - they are very similar, Sybase is much more expensive Sybase/SQL Server - for Java you can use either native Sybase/JSQLDB driver or jTDS that is using TDS protocol and can connect to SQL Server as well, TDS traffic can be dumped and analyzed with hexdump command Sybase/SQL Server - for C++ you can use FreeTDS to connect to any, for Perl - same Sybase/SQL Server - a query can return multiple result sets and return codes, all need to be processes otherwise errors can happen Sybase/SQL Server - sp_help, sp_helptext Sybase/SQL Server - your tables/views/procedures are under DBName/dbo/... Sybase - for C++ on Linux you can use Sybase client API to connect (at least until recently) SQL Server - JDBC driver has a configurable transparent failover capability Oracle - for C++ Linux one can use OTLv4 that is a very powerful yet lightweight wrapper around Oracle client API Oracle compilation (contributors: ammoQ) PLSQL Java Stored Procedures '' is null Hierarchical Query Analytic Functions Oracle Text

  • Depth interpolation for z-buffer, with scanline

    - by Twodordan
    I have to write my own software 3d rasterizer, and so far I am able to project my 3d model made of triangles into 2d space: I rotate, translate and project my points to get a 2d space representation of each triangle. Then, I take the 3 triangle points and I implement the scanline algorithm (using linear interpolation) to find all points[x][y] along the edges(left and right) of the triangles, so that I can scan the triangle horizontally, row by row, and fill it with pixels. This works. Except I have to also implement z-buffering. This means that knowing the rotated&translated z coordinates of the 3 vertices of the triangle, I must interpolate the z coordinate for all other points I find with my scanline algorithm. The concept seems clear enough, I first find Za and Zb with these calculations: var Z_Slope = (bottom_point_z - top_point_z) / (bottom_point_y - top_point_y); var Za = top_point_z + ((current_point_y - top_point_y) * Z_Slope); Then for each Zp I do the same interpolation horizontally: var Z_Slope = (right_z - left_z) / (right_x - left_x); var Zp = left_z + ((current_point_x - left_x) * Z_Slope); And of course I add to the zBuffer, if current z is closer to the viewer than the previous value at that index. (my coordinate system is x: left - right; y: top - bottom; z: your face - computer screen;) The problem is, it goes haywire. The project is here and if you select the "Z-Buffered" radio button, you'll see the results... (note that the rest of the options before "Z-Buffered" use the Painter's algorithm to correctly order the triangles. I also use the painter's algorithm -only- to draw the wireframe in "Z-Buffered" mode for debugging purposes) PS: I've read here that you must turn the z's into their reciprocals (meaning z = 1/z) before you interpolate. I tried that, and it appears that there's no change. What am I missing? (could anyone clarify, precisely where you must turn z into 1/z and where to turn it back?)

  • First time application where to start?

    - by Nazariy
    After many years of searches and copy pasting, I'm still looking for simple solution that can transliterate text input on the fly from one key set to another. There are quite few online services that provide this feature but it still quite annoying to go online all the time. Unfortunately there is not that many applications left which are capable of doing so, and none of them supported by this day. I decided to make my own and at same time to learn something new for my self. The idea is quite simple: application should sit in system tray and wait until input language get changed, for example to Russian. If Russian language is activated, application should start to listen for user key strokes combination and replace them based on custom dictionary for example R = ?, SH = ? etc. I should be able to bind application to any installed language (Russian, Ukrainian, Bulgarian, Belarusian etc.) and customise dictionary for any of them. So my question is: Which language should I chose for this task C++, C# or might be something hardcore like Assembler, as application should work natively with Windows XP/Vista/7 or possibly Mac. (cross platform support is good but my main target is Windows) Due to nature of application behaviour how can I tell anti-virus software that it is not a "Key Logger" and basically not a virus? Where should I start and what should I be aware of? P.S. My current programming knowledge is quite basic, PHP and JavaScript with Object Oriented approach.

  • Who is code wanderer?

    - by DigiMortal
    In every area of life there are people with some bad habits or misbehaviors that affect the work process. Software development is also not free of this kind of people. Today I will introduce you code wanderer. Who is code wanderer? Code wandering is more like bad habit than serious diagnose. Code wanderers tend to review and “fix” source code in files written by others. When code wanderer has some free moments he starts to open the code files he or she has never seen before and starts making little fixes to these files. Why is code wanderer dangerous? These fixes seem correct and are usually first choice to do when considering nice code. But as changes are made by coder who has no idea about the code he or she “fixes” then “fixing” usually ends up with messing up working code written by others. Often these “fixes” are not found immediately because they doesn’t introduce errors detected by compilers. So these “fixes” find easily way to production environments because there is also very good chance that “fixed” code goes through all tests without any problems. How to stop code wanderer? The first thing is to talk with person and explain him or her why those changes are dangerous. It is also good to establish rules that state clearly why, when and how can somebody change the code written by other people. If this does not work it is possible to isolate this person so he or she can post his or her changes to code repository as patches and somebody reviews those changes before applying them.

  • How does a segment based rendering engine work?

    - by Calmarius
    As far as I know Descent was one of the first games that featured a fully 3D environment, and it used a segment based rendering engine. Its levels are built from cubic segments (these cubes may be deformed as long as it remains convex and sides remain roughly flat). These cubes are connected by their sides. The connected sides are traversable (maybe doors or grids can be placed on these sides), while the unconnected sides are not traversable walls. So the game is played inside of this complex. Descent was software rendered and it had to be very fast, to be playable on those 10-100MHz processors of that age. Some latter levels of the game are huge and contain thousands of segments, but these levels are still rendered reasonably fast. So I think they tried to minimize the amount of cubes rendered somehow. How to choose which cubes to render for a given location? As far as I know they used a kind of portal rendering, but I couldn't find what was the technique used in this particular kind of engine. I think the fact that the levels are built from convex quadrilateral hexahedrons can be exploited.

  • Can I re-license Academic Free License code under 2-Clause BSD / ITC?

    - by Stefano Palazzo
    I want to fork a piece of code licensed under the Academic Free License. For the project, it would be preferable to re-license it under the ISC License or the 2-Clause BSD license, which are equivalent. I understand that the AFL grants me things such as limitation of liability, but licensing consistency is much more important to the project, especially since we're talking about just 800 lines of code, a quarter of which I've modified in some way. And it's very important for me to give these changes back to the community, given the fact that this is software relevant to security - I need the public scrutiny that I'll get by creating a public fork. In short: At the top of the file I want to say this, or something like it: # Licensed under the Academic Free License, version 3 # Copyright (C) 2009 Original Author # Licensed under the ISC License # Copyright (C) 2012 Stefano Palazzo # Copyright (C) 2012 Company Am I allowed to do this? My research so far indicates that it's not clear whether the AFL is GPL-Compatible, and I can't really understand any of the stuff concerning re-licensing to other permissive licenses. As a stop gap, I would also be okay with re-licensing under the GPL, however: I can find no consensus (though I can find disagreement) on whether this is allowed at all, and I don't want to risk it, of course.

  • Error installing avogadro with CMake 'lconvert: could not exec No such file or directory'

    - by Orr22
    I'm brand new in ubuntu. I'm trying to install Avogadro. The program need the following packages, which I could install: CMake - OpenBabel 2.3.2 - Qt4 - Git - Eigen2. Here it is the recepy to install the : cd $HOME/src git clone git://github.com/cryos/avogadro.git mkdir -p $HOME/build/avogadro cd $HOME/build/avogadro cmake $HOME/src/avogadro make -j2 sudo make install It was unable to compile, but when I skipped the 'git clone' step it seemed to work just fine. After several stops during the CMake compiling process (software actualizations, get Doxygen, get flex, get bison) I was able to compile. But when I introduce the 'make -j2' command the installation stops as follows: Orr22@javi-87:~/build_avogadro$ make -j2 [ 0%] Built target elementcolor [ 0%] Built target bsdyengine [ 2%] Built target spglib [ 3%] Built target navigatetool [ 4%] Built target tubegen [ 4%] Generating libavogadro_hu.qm [ 6%] Built target OpenQube [ 6%] Generating moc_animation.cxx lconvert: could not exec '/usr/lib/i386-linux-gnu/qt5/bin/lconvert': No such file or directory make[2]: *** [libavogadro/src/libavogadro_hu.qm] Error 1 make[2]: *** Se espera a que terminen otras tareas.... make[1]: *** [libavogadro/src/CMakeFiles/avogadro.dir/all] Error 2 make: *** [all] Error 2 Any suggestions to proceed?

  • .NET development on Macs

    - by Jeff
    I posted the “exciting” conclusion of my laptop trade-ins and issues on my personal blog. The links, in chronological order, are posted below. While those posts have all of the details about performance and software used, I wanted to comment on why I like using Macs in the first place. It started in 2006 when Apple released the first Intel-based Mac. As someone with a professional video past, I had been using Macs on and off since college (1995 graduate), so I was never terribly religious about any particular platform. I’m still not, but until recently, it was staggering how crappy PC’s were. They were all plastic, disposable, commodity crap. I could never justify buying a PowerBook because I was a Microsoft stack guy. When Apple went Intel, they removed that barrier. They also didn’t screw around with selling to the low end (though the plastic MacBooks bordered on that), so even the base machines were pretty well equipped. Every Mac I’ve had, I’ve used for three years. Other than that first one, I’ve also sold each one, for quite a bit of money. Things have changed quite a bit, mostly within the last year. I’m actually relieved, because Apple needs competition at the high end. Other manufacturers are finally understanding the importance of industrial design. For me, I’ll stick with Macs for now, because I’m invested in OS X apps like Aperture and the Mac versions of Adobe products. As a Microsoft developer, it doesn’t even matter though… with Parallels, I Cmd-Tab and I’m in Windows. So after three and a half years with a wonderful 17” MBP and upgraded SSD, it was time to get something lighter and smaller (traveling light is critical with a toddler), and I eventually ended up with a 13” MacBook Air, with the i7 and 8 gig upgrades, and I love it. At home I “dock” it to a Thunderbolt Display.

  • Difference between bug, defect and flaw

    - by Hossein
    I was reading "Software Security: Building Security In" and in the first chapter I faced with 3 terms: bug, defect and flaw. The author gave a definition for each of them but I couldn't completely understand these. Can someone give me some examples for each term? What is a defect and what is a flaw? I think I know what bug is, a bug is a malfunction of a part of system which produces undesirable result, be it crashing on a wrong input or miscalculating a series of computations. Can someone elaborate more and correct me if I am wrong in this? UPDATE To be more precise in the book I mentioned above, they (the words) are presented in a way to make a distinction, that's why I am asking to know more. In that book there are some examples denoting which sample belongs to what and which category. For example: Buffer overflow is said to be a bug and issues in method overriding (subclassing issues) is being related to flaw category. Again race condition handling issues are considered bugs and Error-handling problems (fails open) are told to be flaws! I want more elaboration on these regards.

  • Is this project Structure Valid?

    - by rafuru
    I have a dilemma: In the university we learn to create modular software (on java), but this modularity is explained using a single project with packages (a package for business, another one for DAOS and another one for the model, oh and a last package for frontend). But in my work we use the next structure: I will try to explain: First we create a java library project where the model (entities classes) are created in a package. Next we create an EJB named DAOS and using the netbeans wizard we store the DAOS interfaces in the library project in another package , these interfaces are implemented in the DAOS bean. So the next part is the business logic, we create a business EJB for each group of functions , again using the wizard we store the interface in the java library project in another package then is implemented on the business bean. The final part (for the backend) is a bean that I have suggested: a Facade bean who will gather every method of the business beans in a single bean and this has an interface too that is created in our library project and implemented in the bean. So the next part is call the facade module on the web project. But I don't know how valid or viable is this, maybe I'm doing everything wrong and I don't even know! so I want to ask your opinion about this.

  • backface culling error (in world space)

    - by acrilige
    I write simple software renderer. In my pipeline i have stage of backface culling. But looks like it has some error (see picture). I perform culling right after world transformation (is it correct?). (i can't insert picture in post coz i don't have enough points, so i just upload it (cube model): http://imageshack.us/photo/my-images/705/bcerror.png/) Vector3F view_dir(0.0f, 0.0f, 1.0f); std::vector<Triangle> to_remove; for (Triangle &t : m_triangles) { Vector4F e1 = t.v2 - t.v1; Vector4F e2 = t.v3 - t.v1; Vector3F normal( e1.y * e2.z - e1.z * e2.y, e1.z * e2.x - e1.x * e2.z, e1.x * e2.y - e1.y * e2.x ); normal.Normalize(); float dot = Dot(view_dir, normal); if (dot <= 0) to_remove.push_back(t); } for (Triangle& t : to_remove) m_triangles.erase(std::remove(m_triangles.begin(), m_triangles.end(), t), m_triangles.end()); Camera sits in origin and points in screen (RH). What is the reason? For better explanation i upload picture with cube rotation screenshots: http://imageshack.us/photo/my-images/842/bcmove.png/ UPDATED: The error occurs only when triangle has non-zero offset from origin UPDATED 2: If i process backface culling in clip space (after transforming all vertices with view and projection matrix), and just check z coordinate of triangle normal - it works perfect... Can i perform culing RIGHT BEFORE view/proj transforms? In this case looks like culling will not depends of projection and it's not right?.. UPDATED 3: I found answer and will post it in two hours - again coz of reputation lack.
