• Can I use GPL software in a commercial application

  - by Petah

  I have 3 questions about the GPL here: If I use GPL software in my application, but don't modify or distribute it, do I have to release my application under the GPL? What if I modify some software that my application uses. Then do I have to release my application under the GPL, or can I just supply the modified software under the GPLs terms. And what if I use GPL software, but don't modify it, can I distribute it with my application? My case in point is, I have a PHP framework which I use the GeSHi library to highlight some output. Because GeSHi is GPL, does my framework have to be GPL? Can I modify GeSHi for particular use cases of my application if I supply the modifications back to the GeSHi maintainers? Can I redistribute my framework with GeSHi?

• Is this the right strategy to convert an in-level order binary tree to a doubly linked list?

  - by Ankit Soni

  So I recently came across this question - Make a function that converts a in-level-order binary tree into a doubly linked list. Apparently, it's a common interview question. This is the strategy I had - Simply do a pre-order traversal of the tree, and instead of returning a node, return a list of nodes, in the order in which you traverse them. i.e return a list, and append the current node to the list at each point. For the base case, return the node itself when you are at a leaf. so you would say left = recursive_function(node.left) right = recursive_function(node.right) return(left.append(node.data)).append(right);` Is this the right approach?

• Can I have a .desktop Launcher for both Python2 and Python3 depending on version installed?

  - by Takkat

  After very few issues only I moved my application from Python2 to Python3 making sure it will still run with Python 2.7, and hence has python = 2.7 as dependency only. This was mainly done because Python3, and some dependencies are not installed in a default 12.04 LTS, and I do not want my users to have to install all Python3 only to run my script. When I create an appname.desktop launcher I now need to decide if it starts my application using Python2, or Python3 like EXEC=python /path/app.py EXEC=python3 /path/app.py But what I would like it to do is to Launch the application with the Python3 interpreter if Python3 is installed. Otherwise use Python2 if Python3 is not installed. How can this be done? Do I need to tell it in my package installation script, or can I have a launcher which can handle both (in case people install Python3 after they had installed my script)?

• How do you make comp.sci students and future programmers aware of the various software licenses and the nuances of it ?

  - by Samyak Bhuta

  To be specific How would you include it as part of curriculum ? Would it be too boring to just introduce them as a pure law subject ? Are there any course structure available or can we derive one ? What are the books that could be used ? I would like to see that - after going through the course - candidate is well aware of "what software licenses are and what they are good for". Various implications of not knowing it in it's proper sense. What licenses they should use for their own code. What to consider when they are trying to use certain libraries or tools in their project and gauge risks/rewards associated with it. The idea is to let them make informed choices when they are professionals/practitioners in field of programming and not make them substitute for a lawyer or even a paralegal who is going to fight the case or draft things.

• Indexing File Contents

  - by Rafid K. Abdullah

  People seem to have already asked about indexing file system: What options are there for indexing my filesystem? Alternatives to OS X's Spotlight? but I want to actually just index a certain working directory and be able to do that manually (so that I make sure my search is correct). Basically, I am on working a project and I need be able to search in contents quickly. I already use 'locate' and 'updatedb' commands, but those search for file names only. I am looking for similar commands but file contents. Just in case you are wondering why I don't use tracker also like answered in the two posts, tracker have a set of prespecified folders to search in them, and whenever you make a search, you search in all of them. What I want is to be able to search in every project separately.

• Unit testing time-bound code

  - by maasg

  I'm currently working on an application that does a lot of time-bound operations. That is, based on long now = System.currentTimeMillis();, and combined with an scheduler, it will calculate periods of time that parametrize the execution of some operations. e.g.: public void execute(...) { // executed by an scheduler each x minutes final int now = (int) TimeUnit.MILLISECONDS.toSeconds(System.currentTimeMillis()); final int alignedTime = now - now % getFrequency() ; final int startTime = alignedTime - 2 * getFrequency(); final int endTimeSecs = alignedTime - getFrequency(); uploadData(target, startTime, endTimeSecs); } Most parts of the application are unit-tested independently of time (in this case, uploadData has a natural unit test), but I was wondering about best practices for testing time-bound parts that rely on System.currentTimeMillis() ?

• Are there any formalized/mathematical theories of software testing?

  - by Erik Allik

  Googling "software testing theory" only seems to give theories in the soft sense of the word; I have not been able to find anything that would classify as a theory in the mathematical, information theoretical or some other scientific field's sense. What I'm looking for is something that formalizes what testing is, the notions used, what a test case is, the feasibility of testing something, the practicality of testing something, the extent to which something should be tested, formal definition/explanation of code coverage, etc. UPDATE: Also, I'm not sure, intuitively, about the connection between formal verification and what I asked, but there's clearly some sort of connection.

• What to do when issue-tracker is down?

  - by Pablo

  It has happened in our team that our issue-tracker is down. Happens about once a week now (yes, wow), and there's not really much we can do to get it back up, since it's hosted by our client in a different timezone. It sometimes takes several hours for it to be operative again. In the meanwhile, we can't really tell which issues we were working on, and in case we do, we cannot update those issues, as in moving them through the workflow, logging used hours, checking the issue's description, leaving comments, and so on. So the question is: how can we, as a team, work in the meanwhile so that when the issue-tracker is up again, we have the least possible hassle updating it with what we've been working?

• Audio Panning using RtAudio

  - by user1801724

  I use Rtaudio library. I would like to implement an audio program where I can control the panning (e.g. shifting the sound from the left channel to the right channel). In my specific case, I use a duplex mode (you can find an example here: duplex mode). It means that I link the microphone input to the speaker output. I seek on the web, but I did not find anything useful. Should I apply a filter on the output buffer? What kind of filter? Can anyone help me? Thanks

• Rotate an image in a scaled context

  - by nathan

  Here is my working piece of code to rotate an image toward a point (in my case, the mouse cursor). float dx = newx - ploc.x; float dy = newy - ploc.y; float angle = (float) Math.toDegrees(Math.atan2(dy, dx)); Where ploc is the location of the image i'm rotating. And here is the rendering code: g.rotate(loc.x + width / 2, loc.y + height / 2, angle); g.drawImage(frame, loc.x, loc.y); Where loc is the location of the image and "width" and "height" are respectively the width and height of the image. What changes are needed to make it works on a scaled context? e.g make it works with something like g.scale(sx, sy).

• Spring can commit Transaction in finally block with RunTimeException in try block [migrated]

  - by Chance Lai

  The project used Spring + Hibernate Sample code: public void method(){ try{ dao.saveA(entityA); throw RuntimeException; dao.saveB(entityB); }catch(RuntimeException e){ throw e; }finally{ dao.saveC(entityC) } } Finally, just entityC will be saved in database in test. I think saveA, saveB, saveC in the same transaction,they should not be committed. In this case, I want to know why entityC is committed. How does Spring do this in the finally block?

• Why would I want to install node.js in my Rails Application?

  - by Crazy JIm

  Okay guys, I'm super confused. I thought node.js was a sever side framwork, basically the js version of Ruby's Rails or PHP's Zend. However, I'm having some difficulty with turbolinks, and it seems to be the way to fix it is through installing node.js I mean, I don't understand this at all. How can two frameworks work together like this? Also, it's not a gem (that REALLY would have confused me), you have to install node.js it onto your local machine by running (in the case of Ubuntu) sudo apt-get install nodejs Firstly, how does this totally separate framwork have any bearing on rails? Secondly, surely this isn't fixing the problem forever? When you specify a gem in your gemfile, the server knows what external libraries to install. How does the server know to install nodejs?

• Daylight saving time: Annoying and pointless [closed]

  - by polemon

  Daylight saving time is a big annoyance for me. Not just from the standpoint, that I never know when we set our clocks an hour ahead or an hour back. Setting the clock ahead or back disturbs my time organization, and is responsible for my bad mood around that day. From the standpoint of a programmer, it's no less annoying. you always have to check whether it isn't "that date" in the year, when you have to work with local time. I hear people have the same views on this that I have. also, I don't see any benefits from it. The supposedly added "extra hour" of sunlight; I don't feel that. In case you live in a region where daylight savings is observed (like in Germany, where I live), please tell me how you manage the annoyances that come with it, and (if possible) how to get rid of it, once and for all...

• Can not resolve hostnames on Xubuntu computers

  - by P Curtis

  I have a network of computers which has been running for many years. I have changed two of those to Xubuntu 11.10 and found I can no longer connect by ssh using the host-name from any other machine. I can connect and ping by IP although ping is very slow in one case (~200ms). All other machines are fine including another with Ubuntu 11.10. Host-name resolution works from Xubuntu machines to other networked machines. I am using wins resolution and have checked settings in /etc/nsswitch.conf are the same as my working Ubuntu systems. What is different in Xubuntu networking that I might have missed?

• Agile bug fixing - what's the preferred process for testing?

  - by Andrew Stephens

  When a bug is fixed, the dev set its status to "resolved" and the bug is reassigned back to the person that created it. In our case this is usually the product owner - we don't have dedicated testers. But what's a good process for controlling how/when the PO tests the software? Should he be given the latest build after each bug is resolved/checked-in? Or what about every morning? Or should he only receive a build at (or close to) the end of the iteration, to include all of that iteration's new functionality and bug fixes? We are using TFS by the way.

• What should my "code sample" look like?

  - by thesunneversets

  I've just had quite a good phone interview (for a CakePHP-related position, not that it's especially important to the question). The interviewer seemed to be impressed with my resume and personality. At the end, though, he asked me to email him a code sample from my existing work project, "to check you're not secretly a terrible programmer, ha ha!" I'm not too worried that my code can't stand on its own two feet, but I'm very much an intermediate programmer rather than an expert. What obvious pitfalls should I make sure my code sample doesn't fall into, in case they rule me out on the spot? Secondly, and this is probably the harder part of the question to answer, what features in a code sample would be so impressive that they would instantly make you much more favourably inclined towards the programmer? All ideas or suggestions welcomed!

• 2D object-aligned bounding-box intersection test

  - by AshleysBrain

  Hi all, I have two object-aligned bounding boxes (i.e. not axis aligned, they rotate with the object). I'd like to know if two object-aligned boxes overlap. (Edit: note - I'm using an axis-aligned bounding box test to quickly discard distant objects, so it doesn't matter if the quad routine is a little slower.) My boxes are stored as four x,y points. I've searched around for answers, but I can't make sense of the variable names and algorithms in examples to apply them to my particular case. Can someone help show me how this would be done, in a clear and simple way? Thanks. (The particular language isn't important, C-style pseudo code is OK.)

• Can't access Windos 7 OS in Ubuntu

  - by Myers

  When I try and Access my Windows 7 OS I get the following memo and I have no idea what to make of the code. Error mounting /dev/sda2 at /media/name/Windows7_OS: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda2" "/media/name/Windows7_OS"' exited with non-zero exit status 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to read NTFS $Bitmap: Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details. What should I do ?

• How to create a KDE start application menu launcher that launches the search and launch desktop?

  - by davorao

  Now i love the plasma-netbook aka the "search and launch" interface but i would want to be able to have it appear on demand and not sit as the desktop default in the back of my windows. So what i imagine is having a application launcher be created which on activation brings up the "search and launch" feature allowing for easy access of your favorites or have that slick interface to find what your looking for. I'm aware that krunner solves a similar use-case but search and launch would be more of an Unity Dash type of search, whereas krunner is more useful when u exactly know what your looking for. And to summarize my question, since I'm clueless as to how this would be done, I'm lookinf for someone who could tell me how hard it would be to do it.

• Are there well-known PowerShell coding conventions?

  - by Tahir Hassan

  Are there any well-defined conventions when programming in PowerShell? For example, in scripts which are to be maintained long-term, do we need to: Use the real cmdlet name or alias? Specify the cmdlet parameter name in full or only partially (dir -Recurse versus dir -r) When specifying string arguments for cmdlets do you enclose them in quotes (New-Object 'System.Int32' versus New-Object System.Int32 When writing functions and filters do you specify the types of parameters? Do you write cmdlets in the (official) correct case? For keywords like BEGIN...PROCESS...END do you write them in uppercase only? It seems that MSDN lack coding conventions document for PowerShell, while such document exist for example for C#.

• Where does the URL parameter "?chocaid=397" come from?

  - by unor

  In Google Webmaster Tools, I noticed that my front page was indexed two times: example.com/ example.com/?chocaid=397 I know that I could fix this with the use of link type canonical, but I wonder: Where does this parameter come from? There are various sites that have pages indexed with this very parameter/value: https://duckduckgo.com/?q=chocaid%3D397. I looked for similarities between these sites. but couldn't find a conclusive one: It's often the front page, but not in every case. Some are NSFW, but not all. When one domains' URL has this parameter, often other subdomains of the same domain have it, too. Examples Wikipedia entry Microsoft Codeplex

• OWSM vs. OEG - When to use which component - 11g

  - by Prakash Yamuna

  A lot of people both internal to Oracle and customers keep asking about when should OWSM be used vs. OEG. Sometime back I posted Oracle's vision for layered SOA security Here is a quick summary: Use OWSM in Green Zone Use OEG in Red Zone (DMZ) If you need end-to-end security in which case they will want both OWSM and OEG. This is the topology I would recommend for most customers. If you need only Green Zone security - then use OWSM in conjunction with Oracle FMW products like SOA Suite, OSB, ADF, WLS, BI, etc both on the Client Side and Service Side (assuming you are using FMW technologies for both Clients and Services). If you need only Red Zone security - then use OEG on the Service Side. You can use OWSM for the Client Side if you are using FMW to build your clients.

• How should programmers handle identity theft?

  - by Craige

  I recently signed up for an iTunes account, and found that somebody had fraudulently used MY email to register their iTunes account. Why Apple did not validate the email address, I will never know. Now I am told that I cannot use my email address to register a new iTunes account, as this email address is linked to an existing account. This got me thinking, as developers, database administrators, technical analysts, and everything in between, how should we handle reports of a fraud account? Experience teaches us never to re-assign identifying credentials. This can break things and/or cause mass confusion, especially in the realm of the web. That is, if we are are needing to reassign an identifying user credential we can very likely break a users bookmark by making a page render data that previously did not exist at that location. So if we have been taught not to re-assign details like these, how should we handle such a case where an account is discovered to be a fraud and the owner of the identity (e-mail or user name) wishes to claim this detail for their account?
