  • Isn't GPL enough to make a software free as in free speech?

    - by user61852
    I have read people rebutting the fact that a certain software is free as in free speech, even when it is licensed under GPL. Some say Java isn't free because to obtain a professional certification you must get it from Oracle. Some say Java JDK is not free to re-distribute. Some people even say the openJDK is not free or open. But Java is officially GPL. Doesn't GPL explicitly mean you are free to re-distribute ? Isn't GPL enough to make a software free as in free speech ? How can Java be both GPL and not-free as in free speech ? Is there is any license that trully makes a software free beyond any possible subjetive point of view? EDIT: These question is not about names or trademarks, it's about the code.

  • Determining Cost of API Calls

    - by Sam
    [This is a cross-post originally posted by me in SO. I think the question is more appropriate here.] I was going through the adwords API and came across their rate sheet - http://code.google.com/apis/adwords/docs/ratesheet.html . They charge $0.25 per 1000 API units and under the 'Operation Costs' sections list the cost (in API units) of different API calls. I am curious - based on what factors do they (and others API developers) calculate the cost of an API call? Is there any simple formula or a standard way to determine this? Note: When I say 'cost' of an API call, I don't mean the money but the API units. For example, how do you determine one API call costs 100 'units' and another 1000?

  • No Window Options in Cairo Dock

    - by Blind Fish
    I'm not even sure how to describe this properly. I'm running Cairo Dock on Ubuntu 12.04 LTS and I've noticed that I no longer have the top bar of my windows. I mean, I have the bar itself, but it's empty aside from the name of the window and the close / resize boxes. For instance, a simple Nautilus window would have, when you move the cursor to the top bar, a list of options such as View / Edit etc. I have nothing like that for any window or application. It's just solid black. This is a huge problem and I'm not sure what the issue is. Has anyone else experienced this?

  • How do you answer "Rate yourself" questions?

    - by Vinoth Kumar
    Hi , I have been frequently asked questions like "Rate yourself in java" It goes like interviewer : Rate yourself in java on the scale of 10 me: 9 interviewer : Rate yourself in J2EE me : 8 .... But really I just come up with arbitrary numbers. Sure I know Java well , but what does it mean to say "9 out of 10" . I think it is a very subjective question, that does not make sense overall. The problem is ,if I say 9 , If I am not able to answer any question , the interviewer might think , "this guy just said 9" . On the other hand If I said 6 , there is a good chance the interviewer might think "He rates himself this low...not good" How do you respond to such questions ?

  • External USB hard drive makes noises when the computer is turned off

    - by Amir Adar
    I have an external USB hard drive of 500GB. I can't tell what model it is exactly, as nothing specific is written on it and I don't have the box anymore. I use it as a backup disk. It works absolutely fine when the computer is turned on: no problems with writing or reading, and everything is done in dead silence. However, if I turn the computer off and the disk is still connected, it stays on and makes clicking noises. For that reason I only connect it when I need to back up or restore. Does that mean there's a problem with the disk, or with some preferences in the system itself? Or something else?

  • What is the need for 'discoverability' in a REST API when the clients are not advanced enough to make use of it anyway?

    - by aditya menon
    The various talks I have watched and tutorials I scanned on REST seem to stress something called 'discoverability'. To my limited understanding, the term seems to mean that a client should be able to go to http://URL - and automatically get a list of things it can do. What I am having trouble understanding - is that 'software clients' are not human beings. They are just programs that do not have the intuitive knowledge to understand what exactly to do with the links provided. Only people can go to a website and make sense of the text and links presented and act on it. So what is the point of discoverability, when the client code that accesses such discoverable URLs cannot actually do anything with it, unless the human developer of the client actually experiments with the resources presented? This looks like the exact same thing as defining the set of available functions in a Documentation manual, just from a different direction and actually involving more work for the developer. Why is this second approach of pre-defining what can be done in a document external to the actual REST resources, considered inferior?

  • Do most programmers cut & paste code?

    - by John MacIntyre
    I learned very early on that cutting & pasting somebody else's code takes longer in the long run that writing it yourself. In my opinion unless you really understand it, cut & paste code will probably have issues which will be a nightmare to resolve. Don't get me wrong, I mean finding other peoples code and learning from it is essential, but we don't just paste it into our app. We rewrite the concepts into our app. But I'm constantly hearing about people who cut & paste, and they talk about it like it's common practice. I also see comments by others which indicate it's common practice. So, do most programmers cut & paste code?

  • how to save a png as a smaller file but the same resolution?

    - by Radek
    not sure what stackexchange site is the best for this question. I have a scanned jpg file with below properties and size 8.5MB pixel dimension: 2468 × 3484 pixels print size: 208.96 × 294.98 millimeters resolution: 300 × 300 ppi I need to save the file as png while the size cannot be bigger than 4MB. The most important is that the size of picture must remain the same. I mean that the object size in the picture must stay the same. Could anybody tell me what is used to define the size of the objects in the picture?

  • Phones, Nokia, Microsoft and More

    - by Bill Evjen
    The phone revolution that is under way at the moment is insanely interesting and continuously full of buzz about directions, failures, and promises. The movement started with Apple completely reinventing what a smart phone was all about and now we have the followers. Though – don’t dismiss the followers, they are usually the ones that come out with the leap frog products when most of the world is thinking about jumping on. Remember the often used analogy – the USA invented the TV – but it was Japan that took it to the next level and now all TVs are from somewhere else other than the USA. Really there are two camps for the phones – the Cool Kids and other kids that no one wants to hang out with anymore. When it comes to cool – for some reason, the phone is an important part of that factor. Everyone wants to show their phone and its configuration (apps installed, etc) to their friends as a sign of (1) “I have money” and (2) I have smarts/tastes/style/etc when it comes to my applications that are on my phone. For those that don’t know – the Cool Kids include: Apple – this is quite obvious as everything Apple produces is in the cool camp. Just having an Apple product on your person means you can dance. Google – this is one of the more interesting releases as they have created something called Android (which in it’s own right is a major brand in itself). Microsoft – you might be saying “Really, Microsoft is cool?”. I would argue that they are indeed cool as it is now associated with XBOX 360, Kinect, and Windows 7. Gone are the days of Bob and that silly paperclip. Well – that’s it. There is nobody else I would stick in that camp. The other kids that weren’t picked for that dodgeball team include: Nokia Motorola Palm Blackberry and many many more The sad part of all this is that no matter what this second camp does now, it won’t be able to get out of this bucket easily. They will always be associated as yesterday’s technology and that association will drive the sales of the phone purchasers of the world. For those in that group, the only possible way out is to get invited to the cool club by one of the cool club members in the hope that their coolness somehow rubs off. To me, this is the move that Nokia is making. They are at this point where they have realized that they don’t have the full scope of the required end to end solution to make this all work. They have the plants to build the phones and the reach of the retailers that sell what they have. What they are missing is the proper operating system for the new world of multi-touch form factor phones. Even the companies that come up with some sort of new operating system for this type of new device, they are still associated with the yesterday and lack the developer community behind them to be the real wave of adoption that this market needs. Think about that – this is a major different between Nokia/Blackberry when you compare it to the likes of Apple, Google, and Microsoft. These three powerhouses having a very large and strong development community that will eagerly take on new initiatives using the skillsets that they have already cultivated over the years of already working with the company. This then results in a plethora of applications that are then placed on an app store of some kind. The developer gets a cut and then Apple/Google/Microsoft then get their cut. It is definitely a win-win. None of the other phone companies and wannabies can provide the same results. What Microsoft was missing was the major phone manufactures coming on board to create and push forward with the phones that are required to start the wave. This is where Nokia can come in and help Microsoft. They have the ability to promote the Windows Phone operating system on a new wave of phones. This does mean that Nokia will sell phones, but they lose out on the application store that they might have been thinking about making some money on as well as controlling the end to end solution. What is interesting is in questioning to oneself if Microsoft will purchase Nokia. It really depends upon how they want to compete and with whom Microsoft views as the major competitor. For instance, they can purchase Nokia and have their own hardware company and distribution network for phones – thereby taking on a model that is quite similar to Apple. On the other hand, they could just leave it up to the phone hardware companies such as Nokia and others to build and promote phones in a model that is similar to Google. Both ways have pluses and minuses. If they own the phone manufacturer, they really can put some thought into the design and technical specifications of the phone that is really designed to exactly how they want it. Microsoft has shown that they have this ability – especially with the XBOX initiative they have done over the years. Think about how good and powerful they have moved forward with XBOX – and I am not talking about just copying what others are doing, but coming up with leapfrog products that are steps ahead of everyone else. Though, if they didn’t do it themselves, they could then leave it up to the phone manufacturers to drive each other to build better and better phones that run the Microsoft OS – competition drives better products. We have seen this with the Android line of phones that are out there on the market. I have read a lot about Nokia investors really upset about the new Microsoft relationship – but really, this is a great thing. I for one am a fan of this relationship (I am also a Nokia stock holder btw). This will mean better days for Nokia.

  • Which paradigm to use for writing chess engine?

    - by poke
    If you were going to write a chess game engine, what programming paradigm would you use (OOP, procedural, etc) and why whould you choose it ? By chess engine, I mean the portion of a program that evaluates the current board and decides the computer's next move. I'm asking because I thought it might be fun to write a chess engine. Then it occured to me that I could use it as a project for learning functional programming. Then it occured to me that some problems aren't well suited to the functional paradigm. Then it occured to me that this might be good discussion fodder.

  • rc.local is not always executed upon boot

    - by starcorn
    Hey, I have some weird problem with the rc.local file which is located in /etc/rc.local the thing is that it is not always running when I boot up the laptop. Maybe every second time, I haven't counted. Anyway when that happens I have to manually go to terminal and type sudo /etc/init.d/rc.local start, which kinda kills the purpose of having this script. Anyone know what the problem could be? EDIT Since this wasn't obvious. This is an issue where I make a fresh boot up. Which mean I have shut down the computer. And next time when I boot up the computer, the rc.local file is randomly deciding whether it will automatically start or not. Here's a copy of what my rc.local file contains echo -n 255 > /sys/devices/platform/i8042/serio1/serio2/sensitivity echo level 2 > /proc/acpi/ibm/fan touch /home/starcorn/Desktop/foo rfkill block bluetooth exit 0

  • What should be included in risk management section of software's architecture documentation?

    - by Limbo Exile
    I am going to develop a Java application (a Spring Web application that will be used to extract data from various data sources) and I want to include risk management of the software in the architecture documentation. By risk management (I am not sure if this is the right name) I mean documenting possibilities of what can go wrong with the software and what to do in those cases. At first I tried to draft some lists, including things like database performance decrease, change of external components that the software interacts with, security breaches etc. But as I am not an experienced developer I cannot rely on those drafts, I don't think they are exhaustive. I searched web hoping to find something similar to the Joel Test or to find any other resource that will cite the most popular causes of problems that should be included and analyzed in risk management documentation, but I haven't found much. Finally, my question is: What should be included in risk management section of software's architecture documentation?

  • Do you have a plan for your digital assets after you die?

    - by pablo
    After reading this question I remembered of a news article about some websites that manage your online identity after you pass away. Have you planned what to do with your digital assets once you go? I'd imagine that your online footprint is as important as anything you leave of material value. I mean, what would be the difference of that open-source project that you created to the money and savings that you had? How would you like to have your identity managed after you pass away? Would you prefer to go "off the grid"? It's a sensitive topic and I never met anyone who prepared for it.

  • How do I limit the size of my syslog?

    - by Wayne Werner
    I've got my mom's computer running Ubuntu 12.04 LTS. It's been working just fine but all of the sudden syslog has been filling up. And by filling up I mean I just deleted a /var/log/syslog that was 400GB in size. Yes - Gigabytes. While I'm sure there was some useful information in there, I'm not sure that 400GB is any kind of information to sift through. And what's really amazing about it is that it happened within a period of 8 hours - I had ran df around noon, and between then and now her drive filled up 30% (from just under 70% to 100%). What could be causing this and how could I fix it?`

  • Implement Tree/Details With Taskflow Regions Using EJB

    - by Deepak Siddappa
    This article describes on Display Tree/Details using taskflow regions.Use Case DescriptionLet us take scenario where we need to display Tree/Details, left region contains category hierarchy with items listed in a tree structure (ex:- Region-Countries-Locations-Departments in tree format) and right region contains the Employees list.In detail, Here User may drills down through categories using a tree until Employees are listed. Clicking the tree node name displays Employee list in the adjacent pane related to particular tree node. Implementation StepsThe script for creating the tables and inserting the data required for this application CreateSchema.sql Lets create a Java EE Web Application with Entities based on Regions, Countries, Locations, Departments and Employees table. Create a Stateless Session Bean and data control for the Stateless Session Bean. Add the below code to the session bean and expose the method in local/remote interface and generate a data control for that.Note:- Here in the below code "em" is a EntityManager. public List<Employees> empFilteredByTreeNode(String treeNodeType, String paramValue) { String queryString = null; try { if (treeNodeType == "null") { queryString = "select * from Employees emp ORDER BY emp.employee_id ASC"; } else if (Pattern.matches("[a-zA-Z]+[_]+[a-zA-Z]+[_]+[[0-9]+]+", treeNodeType)) { queryString = "select * from employees emp INNER JOIN departments dept\n" + "ON emp.department_id = dept.department_id JOIN locations loc\n" + "ON dept.location_id = loc.location_id JOIN countries cont\n" + "ON loc.country_id = cont.country_id JOIN regions reg\n" + "ON cont.region_id = reg.region_id and reg.region_name = '" + paramValue + "' ORDER BY emp.employee_id ASC"; } else if (treeNodeType.contains("regionsFindAll_bc_countriesList_1")) { queryString = "select * from employees emp INNER JOIN departments dept \n" + "ON emp.department_id = dept.department_id JOIN locations loc \n" + "ON dept.location_id = loc.location_id JOIN countries cont \n" + "ON loc.country_id = cont.country_id and cont.country_name = '" + paramValue + "' ORDER BY emp.employee_id ASC"; } else if (treeNodeType.contains("regionsFindAll_bc_locationsList_1")) { queryString = "select * from employees emp INNER JOIN departments dept ON emp.department_id = dept.department_id JOIN locations loc ON dept.location_id = loc.location_id and loc.city = '" + paramValue + "' ORDER BY emp.employee_id ASC"; } else if (treeNodeType.trim().contains("regionsFindAll_bc_departmentsList_1")) { queryString = "select * from Employees emp INNER JOIN Departments dept ON emp.DEPARTMENT_ID = dept.DEPARTMENT_ID and dept.DEPARTMENT_NAME = '" + paramValue + "'"; } } catch (NullPointerException e) { System.out.println(e.getMessage()); } return em.createNativeQuery(queryString, Employees.class).getResultList(); } In the ViewController project, create two ADF taskflow with page Fragments and name them as FirstTaskflow and SecondTaskflow respectively. Open FirstTaskflow,from component palette drop view(Page Fragment) name it as TreeList.jsff. Open SeconfTaskflow, from component palette drop view(Page Fragment) name it as EmpList.jsff and create two paramters in its overview parameters tab as shown in below image. Open TreeList.jsff , from data control palette drop regionsFindAll->Tree as ADF Tree. In Edit Tree Binding dialog, for Tree Level Rules select the display attributes as follows:-model.Regions - regionNamemodel.Countries - countryNamemodel.Locations - citymodel.Departments - departmentName In structure panel, click on af:Tree - t1 and select selectionListener with edit property. Create a "TreeBean" managed bean with scope as "session" as shown in below Image. Create new method as getTreeNodeSelectedValue and click ok. Open TreeBean managed bean and add the below code: private String treeNodeType; private String paramValue; public void getTreeNodeSelectedValue(SelectionEvent selectionEvent) { RichTree tree = (RichTree)selectionEvent.getSource(); RowKeySet addedSet = selectionEvent.getAddedSet(); Iterator i = addedSet.iterator(); TreeModel model = (TreeModel)tree.getValue(); model.setRowKey(i.next()); JUCtrlHierNodeBinding node = (JUCtrlHierNodeBinding)tree.getRowData(); //oracle.jbo.Row Row rw = node.getRow(); Object selectedTreeNode = node.getAttribute(0); Object treeListType = node.getBindings(); String treeNodeType = treeListType.toString(); this.setParamValue(selectedTreeNode.toString()); this.setTreeNodeType(treeNodeType); } public void setTreeNodeType(String treeNodeType) { this.treeNodeType = treeNodeType; } public String getTreeNodeType() { return treeNodeType; } public void setParamValue(String paramValue) { this.paramValue = paramValue; } public String getParamValue() { return paramValue; }<br /> Open EmpList.jsff , from data control palette drop empFilteredByTreeNode->Employees->Table as ADF Read-only Table. After selecting the  Employees result set, in Edit Action Binding dialog window pass the pageFlowScope parameters as shown in below Image. In empList.jsff page, click Binding tab and click on Create Executable binding and select Invoke action and follow as shown in below image. Edit executeEmpFiltered invoke action properties and set the Refresh to ifNeeded, So when ever the page needs the method will be executed. Create Main.jspx page with page template as Oracle Three Column Layout. Drop FirstTaskflow as Region in start facet and drop SecondTaskflow as Region in center facet, Edit task Flow Binding dialog window pass the Input Paramters as shown in below Image. Run the Main.jspx, tree will be displayed in left region and emp details will displyaed on the right region. Click on the Americas in tree node, all emp related to the Americas related will be displayed. Click on Americas->United States of America->South San Francisco->Accounting, only employee belongs to the Accounting department will be displayed.

  • 3D Studio Max biped restrictions?

    - by meds
    I have a stock biped character in 3D studio max which has a jump animation. The problem I have with the jump animation is that there is actual y offset happening inside it which makes it awkward to play while the character is jumping since it's not only jumping in the game world but the jump animation is adding its own height offset. I'm tryuing to remove the jump animations height offset, so far I've found the root node and deleted all its key frames which has helped a bit. The problem I'm having now is that the character still has some height offset and if I try to lower it it has a fake 'ground' that isn't at 0 and the limbs sort of bend on the imaginary floor, si there a way to remove this restriction just for the jump animation? Here's what I mean: http://i.imgur.com/qoWIR.png Any idea for a fix? I'm using Unity 3D if that opens any other possibilities...

  • Do Google's feed statistics include former users?

    - by jjackson
    I'm currently not using any sort of fancy stat tracking software such as feedburner, but I occasionally look at Google's stats in their Webmaster Tools just to get a rough idea of whether the number of subscribers is going up or down. This only gives the number of users subscribed through Google products, as they explain in their help documents: Subscriber stats display the number of Google users who have subscribed to your feeds using any Google product (such as Reader, iGoogle, or Orkut). Because users can subscribe to feeds using many different aggregators or RSS readers, the actual number of subscribers to your site may be higher. I used to use Google Reader very regularly but haven't opened it in a while now. The way I understand it, this will mean that even though I haven't touched any of those feeds in a long time I'm still technically subscribed to them and will therefore be included in Google's statistic. Is this correct? Also since Google runs Feedburner, does this have any effect on their stats as well?

  • How to make background image black-and-white?

    Are there any filters that would make background image to be displayed as black-and-white? What I mean, is this: i have a background image set via css using background: url(/image.png); But now I need to apply a filter so that an image is shown as black-white only. Ideally, I would like to also apply opacity to it. The effect I really trying to achieve is to have background image black/white and on hover over that span element the filter would be removed, revealing the color version. And of cause it has to work in FF, Chrome, IE Can someone help me?

  • Easy way of engaging non-programmers (i.e. designers) into using version control?

    - by Kevin
    What are some key ways of getting your team involved in using version control during development, web development or otherwise? I refuse to work without it, which means anyone involved in the project must also use it. It's just good practice. GUIs like Tower have helped, but the concept of it is either met with anger ('not my job!' kinda attitude), timidness, or just straight up not using it (using FTP instead, circumventing version control for say, dev or deployment). Edit: I should have clarified a little that I don't just mean images/PSDs.

  • How much will cost to hire a developer who have to make a SEO software? [closed]

    - by Victor
    Hey guys, I know NOTHING about software developing but I got an amazing idea about a software. The thing is I want to know how much money I would approximately need to hire someone to do it for me. The software is gonna have a lot of features, everything is relative to SEO - link building with Web 2.0 sites, Blog comments, Video Submittion, Bookmarking, RSS, Ping Mode, Forum register and submittion, Proxy mode, ect. The point is to be all automated! I mean all profile creation is going to be automate! There are a lot of softwares but nothing is doing everything that I want. So I would like to build my own software, use it for on my own and of course I'll sell it too! So how much do you think I would need to be able to order such a software?

    I mean seriously, how do you tackle a guy who even changes our variable names (even though they are reasonable) and sends back the code (after review) like 4 times? I know for sure I'm not that bad a developer! So many times, he enforces his ideals, which are not even best practices in the industry! I point out to him whatever link I can find on the internet trying to prove my point, but in the end he uses his authority to shut us out. Sick and tired. Frustrated. Do I have any way out other than quitting the job?

  • 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?

I can open apps but the Window buttons and the global menu are not visable. Does this mean that I cannot use Unity. I'm running it through Wubi on a Dell Inspiron 1501 laptop. My total ammount of graphics memory is 831MB My dedicated memory is 128MB. The odd thing is is that Windows Aero displays without a problem so why is there a problem with Unity Hope this helps Ben
