  • Mouse buttons and all keyboard buttons except alt and super randomly stops working

    - by bobbaluba
    A couple of times lately, unity appears to not accept button presses from neither the mouse or the keyboard. This happens after a random amount of time, usually a couple of hours, or right after boot. The weird thing is: I can still move the mouse around. I can press alt to get the unity menu thingy (but i can't type anything in it) I can press super to show/hide the unity search. None of the applications seem to get the input Ive tried connecting a second mouse, same issue I can press ctrl+alt+f1 to drop to a shell tty The shell works fine Now, this is definitely a bug, probably in unity(?), but it's hard to search for when I don't know what's causing it. Is there something I can do to debug? I've found some people that appears to be having the same problem with the mouse only, but most of the time, their questions are unanswered or closed for being too specific. What would be a good strategy to fix this? Should I report it as a bug?

  • Is Java free/open source or not?

    - by user1598390
    On November 13, 2006, Sun released much of Java as free and open source software, (FOSS), under the terms of the GNU General Public License (GPL). On May 8, 2007, Sun finished the process, making all of Java's core code available under free software/open-source distribution terms, aside from a small portion of code to which Sun did not hold the copyright. OpenJDK (Open Java Development Kit) is a free and open source implementation of the Java programming language. It is the result of an effort Sun Microsystems began in 2006. The implementation is licensed under the GNU General Public License (GNU GPL) with a linking exception. Why there are still people that say Java is not open source or free as in free speech ? Am I missing something? Is Java still privative ?

  • 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 do I get an Acer Aspire One D270 working?

    - by ronnie
    I was planning to buy Acer Aspire One D270 within a few days and as everybody installs linux on their netbook I was also planning to do that. Now, my question is how is Acer's hardware compatibility with linux and specifically in respect to the new Acer Aspire One D270. Has anybody tried installing linux on these new netbooks. It will be a great help if a D270 user can share his/her experience with linux usage. I read on some forums that there is some linux driver issue with Intel GMA 3600 and that people are not able to adjust their brightness. So, as I am a linux noob is this a major issue or not. Specs: RAM : 2Gb DDR3 Processor: Intel N2600(Cedar Trail) Graphics: Intel GMA 3600 HardDisk: 320Gb 5400 rpm

  • Is software innovation still primarily North American and European? Why, and for how much longer?

    - by limist
    Since this site is read by a global audience of programmers, I want to know if people generally agree that the vast majority of software innovation - languages, OS, tools, methodologies, books, etc. - still originates from the USA, Canada, and the EU. I can think of a few exceptions, e.g. Nginx webserver from Russia and the Ruby language from Japan, but overwhelmingly, the software I use and encounter daily is from North America and the EU. Why? Is history and historical momentum (computing having started in USA and Europe) still driving the industry? And/or, is some nebulous (or real) cultural difference discouraging software innovation abroad? Or are those of us in the West simply ignorant of real software innovation going on in Asia, South America, Eastern Europe, etc.? When, if ever, might the centers of innovation move out of the West? Your experiences and opinions welcome, thanks!

  • As a programmer how do I plan to learn new things in my spare time

    - by priyank patel
    I am a Asp.Net/C# developer, I develop few projects in my spare time. I try to utilize my time as much as I can. I have been working for past 7 months. Suddenly these days I am a bit worried about learning the new stuff that is there for me as a programmer. I develop in my spare time so I don't get enough time to read books or blogs. So my question to some of you guys is how should I plan to learn new things, should I at least dedicate two-three evenings for new stuff, maybe ebooks while travelling is a good option too. How do you people plan to learn,should I also start to develop with whatever I learnt? As far as learning is concerned, should I just pick up the basics and then implement it or I should seek deeper understanding of the subject?

  • Transiltion from maintenance programing to design

    - by andrew wang
    What to do guys do develop a design for a s/w for a given set of requirements? I like many people joined a Semiconductor MNC and got stuck in maintenance for quite a couple of years. My work was usually changing a lines of code for windows drivers supplied by my company or a couple of small script (style like) C programs for validating h/w. As a result I developed the bad habit of 'programming by coincidence'. I have not developed the ability for designing tools/programs from scratch. I was the only s/w member of the local team and thus some grunt work from the well established other site of the company came to be done by me. Now I have moved to a different company and thus finding developing from scratch very difficult. How do I unlearn my bad habit and develop this ability of designing s/w and then coding it ?

  • Getting work done in a small office

    - by three-cups
    I work in an office area of ~450sqft. There are a total of 7 people working in the office. I've been finding it hard to concentrate on my work (writing code) because of the distractions going on around me. The distractions are both work-related and non-work-related conversations. I'm trying to figure out what to do in this situation. I want to be part of the team, and I want to get my work done to the best of my ability. I can easily think of two options that I don't like: Stay where I am, not be able to concentrate and get less work done Move somewhere else. (This is tough because I code on a desktop, so I'm not very mobile.) But what are other options? I'm going to talk this through with my team in the next couple days. Any advice or solutions would be great.

  • Reuse the data CRUD methods in data access layer, but they are updated too quickly

    - by ValidfroM
    I agree that we should put CRUD methods in a data access layer, However, in my current project I have some issues. It is a legacy system, and there are quite a lot CRUD methods in some concrete manager classes. People including me seem to just add new methods to it, rather than reuse the existing methods. Because We don't know whether the existing method is what we need Even if we have source code, do we really need read other's code then make decision? It is updated too quickly. Do not have time get familiar with the DAO API. Back to the question, how do you solve that in your project? If we say "reuse", it really needs to be reusable rather than just an excuse.

  • How to convince management to deal with technical debt?

    - by Desolate Planet
    This is a question that I often ask myself when working with developers. I've worked at four companies so far, and I've noticed a lack of attention to keeping code clean and dealing with technical debt that hinders future progress in a software app. For example, the first company I worked for had written a database from scratch rather than take something like MySQL and that created hell for the team when refacoring or extending the app. I've always tried to be honest and clear with my manager when he discusses projections, but management doesn't seem interested in fixing what's already there and it's horrible to see the impact it has on team morale and in their attitude towards others. What are your thoughts on the best way to tackle this problem? What I've seen is people packing up and leaving and the company becomes a revolving door with developers coming and and out and making the code worse. How do you communicate this to management to get them interested in sorting out technical debt?

  • More Than Headsets: 5 Things You Can Do With Bluetooth

    - by Chris Hoffman
    Your laptop, smartphone, and tablet probably all have integrated Bluetooth support. Bluetooth is a standard that allows devices to communicate wirelessly. Most people are familiar with Bluetooth headsets, but there are more things you can do with Bluetooth. To make two Bluetooth devices work together, you’ll have to “pair” them. For example, you can pair a Bluetooth mouse with your laptop, pair a Bluetooth headset with your phone, or pair your smartphone with your laptop.

  • 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.

  • What's a good data structure solution for a scene manager in XNA?

    - by tunnuz
    Hello, I'm playing with XNA for a game project of myself, I had previous exposure to OpenGL and worked a bit with Ogre, so I'm trying to get the same concepts working on XNA. Specifically I'm trying to add to XNA a scene manager to handle hierarchical transforms, frustum (maybe even occlusion) culling and transparency object sorting. My plan was to build a tree scene manager to handle hierarchical transforms and lighting, and then use an Octree for frustum culling and object sorting. The problem is how to do geometry sorting to support transparencies correctly. I know that sorting is very expensive if done on a per-polygon basis, so expensive that it is not even managed by Ogre. But still images from Ogre look right. Any ideas on how to do it and which data structures to use and their capabilities? I know people around is using: Octrees Kd-trees (someone on GameDev forum said that these are far better than Octrees) BSP (which should handle per-polygon ordering but are very expensive) BVH (but just for frustum and occlusion culling) Thank you Tunnuz

  • Mobile apps suck time with the help of Java ME tech

    - by hinkmond
    Here's a new Flurry Mobile report on how Mobile Apps are sucking up more of our precious minutes in a day, even more than the Mobile Web. See: Mobile Apps suck more than Web Here's a quote: Flurry tracked 85,000 apps on [blah-blah-blah], BlackBerry, [yadda-yadda-yadda] and J2ME mobile devices, and their report includes a breakdown on how users spend their time. Greeeaaaaat... People are spending more time on mobile games and doing more Facebook and Twitter from their cell phones. Just what the world needed. Well, you know what they say: "Time == Money". So, the more time you spend, the more money someone, somewhere is getting... Hinkmond

  • Keystore and Credential Store interplay in OWSM - 11g

    - by Prakash Yamuna
    One of the most common problems faced by customer's is the use of the keystore and it's interplay with the credential store.Here is a picture that describes these relationships.(Click on the picture for a larger image). The picture makes some assumptions in describing the relationship. Some of assumptions are: a) the key used for signing and encryption are the same. b) A keystore can have multiple keys and each key can have it's own alias. In the picture I show only a single key with alias "orakey". c) The keystore being described here is a JKS keystore. Things can vary slightly for other type of keystores. I hope to have a detailed How To that provides the larger picture and then shows these relationships in that context and this picture was created in the context of that How-To. However I think people will find this picture useful on a standalone basis as well. The <serviceInstance> is the entry you will find in jps-config.xml

  • Why are most GNU's software written in C

    - by BallroomProgrammer
    I am a Java developer, and I rarely write GUI program in C. However, I noticed that many GNU's projects, such as PSPP, R, Dia, etc., are written in C, instead of Java or C++. I personally don't mind this, but I am really curious why GNU favors C so much. My understanding is that C is the one that supports the least in object-oriented programming, and today's CS education really emphasizes OOP, as OOP really makes codes more reusable. In this case, why would so many developers choose to develop in C instead of C++ or Java. Does anyone know why GNU's software are so exclusively written in C? Do you think or GNU's software should be written in C++ or Java so that the source code could be more useful to people? Why or why not?

  • How to build a great relationship with your colleagues

How will you get along with them? What if they don’t like you? Have you ever felt you’re „the new guy” and your colleagues have already their own way of talking one to each other, their own jokes? It’s a common feeling and can actually become stressful. I am Norbert, Middleware Presales Intern in Hungary and I’ve been working within Oracle for only 1 month. Joining such a big company has been a challenge from many perspectives. One of them was adapting with the environment and getting to know all my colleagues. You know it’s quite difficult to introduce yourself, to try to liaise with them and find some common topics, so I felt very lucky and comfortable when my manager introduced me to all of my colleagues. It was easier to accommodate and we basically we had a starting point for our discussions. We started to talk about what my position means, for how many years they’ve been within Oracle, other Oracle related topics, but also more personal stuff like what they do after work. Having this opportunity of talking with all of them helped me introduce myself in a proper way and actually I told them many things about myself. Networking wasn’t my best skill, but these first days were really helpful from a network point of view. What else can you do to get along with your colleagues? One second thing I consider as being really helpful in networking is asking work-related questions. For instance, when you don’t know how to do something or don’t understand it, asking one of your colleagues will also help you to make a connection with him and you could easily continue the discussion with some other topics which are more personal. It’s a very effective strategy and in a company like Oracle people are very willing to help you with your tasks and perform at a high level. If you see your colleagues going to lunch, you should join them. It will help you become part of their community, finding out what’s new in their lives, you’ll, step-by-step, take part in their conversations and be up to date with the hot topics they talk about. One other opportunity of becoming part of your colleagues’ community are the internal events. Subscribing to the local free time activities mailing list is very useful for finding out information about when they’re going out and have a drink or attending all sorts of events. For instance, this is how I’ve found out about a party within Oracle that most of the employees here attend. It’s a wonderful opportunity for chatting and make a stronger connection to some of them. How important is attending these events? Think about how much time you spend at work. You’d like to enjoy your work and the environment, so getting along with your colleagues is a nice thing to have. I recently attended a corporate party whose purpose was to facilitate the interaction and communication between employees. It was a real success and we had a lot of fun, especially because it was a costume party.  All the fancy dresses and funny clothes we wore made the atmosphere really enjoyable. It was easy to liaise with colleague with whom I had never interacted with before. There was a friendly spirit among us, chatting about personal stuff and about various pleasant things. Working in an international company is not an easy thing because you interact with many people and they have different styles, but all these opportunities of informal interaction are a good way to adapt to the new working environment.

  • Installing Perl modules and dependencies with non-root and without CPAN [migrated]

    - by Eegabooga
    I have been writing Perl scripts for my work and the machine that I have been given to work on makes installing Perl modules difficult: We cannot have gcc on my machine for security reasons, so I cannot use CPAN to install modules, for most modules. I do not have access to the root account. Usually, when I want to install a module, I put in a request and I have to wait a day or two before it gets installed. I know that nobody would have a problem with me installing them myself, so to save everyone's time and my sanity I would like to install them myself. It's just an issue of how to best do that. I have talked to various people and they said to use an RPM to install them (to get around not having gcc). However, when trying to install modules from RPMs, it does not handle the dependencies so I would manually need to handle the dependencies, which could take a while. How can I best install Perl modules with these limitations?

  • What's the best way of marketing to programmers?

    - by Stuart
    Disclaimer up front - I'm definitely not going to include any links in here - this question isn't part of my marketing! I've had a few projects recently where the end product is something that developers will use. In the past I've been on the receiving end of all sorts of marketing - as a developer I've gotten no end of junk - 1000s of pens, tee-shirts and mouse pads; enough CDs to keep my desk tea-free; some very useful USB keys with some logos I no longer recognise; a small forest's worth of leaflets; a bulging spam folder full of ignored emails, etc... So that's my question - What are good ways to market to developers? And as an aside - are developers the wrong people to target? - since we so often don't have a purchasing budget anyways!

  • Random number generation algorithm for human brains?

    - by Magnus Wolffelt
    Are you aware of, or have you devised, any practical, simple-to-learn "in-head" algorithms that let humans generate (somewhat "true") random numbers? By "in-head" I mean.. preferrably without any external tools or devices. Also, a high output (many random numbers per minute) is desirable. Asked this on SO but it didn't get much interest. Maybe this is better suited for programmers.. :) I'm genuinely curious about anything that people might have come up with on this problem.

  • Audiobooks for programmers?

    - by Zoot
    I'm a programmer with a two-hour round trip commute to work each day. I'd like to fill some of that time with audiobooks about software development. Any audiobooks that would help me become a better programmer would be appreciated. I'm thinking that books about design patterns and non-fiction about computing history might be good here, but I'm open to anything. Keeping in mind that I will be listening to this in a car, what are the best audiobooks that I can listen to? EDIT: Many people have also suggested podcasts. This is appreciated, but since podcasts arrive in a constantly arriving stream of data rather than as a finite amount of data, ways to juggle all of these different content streams would also be appreciated. To be more specific to my situation, my commuting vehicle has an MP3 CD player, USB input for MP3 files, and AUX input. I own Android and webOS devices that can be plugged into the AUX input.

  • What is a generalized form creator that runs on .NET / Windows?

    - by Josh
    At the institution that I'm at, we've been looking for web applications that enable users to create and deploy their own forms. Similar applications are Wufoo, and google forms. Unfortunately, those solutions will not work for us, because we are required to host all data and information on our own servers. I've found a few solutions that are written in PHP, but at this point, it doesn't appear that this is acceptable. I've tried searching for ".net form creator" but unfortunately, when you search for ".net forms" you get a lot of results relating to created asp.net webforms, which is not what we're looking for at all. I've been told that finding a solution that runs on .NET and windows servers with either Oracle or MSSQL databases would be much more acceptable. I've found a few, but they are open source, and the IS Security people are not kind to those solutions, despite my attempts to show otherwise. If anyone knows of some solution out there, I would greatly appreciate you passing on the names of those applications!

  • What are some easy techniques to scan books for new information?

    - by aditya menon
    I find it irresistible to keep purchasing cheap programming and technical e-books in fields such as Drupal, PHP, etc., and also compulsively download free material made available such as those from Microsoft's developer blog... The main problem with the large library I've developed is that there are many chapters (especially the first few) in these books packed with information I already know, but with helpful tidbits hidden in between. The logical step would be to skip those chapters and read the ones I don't seem to know anything about, but I'm afraid I may lose out on really important information this way. But naturally it is tedious to have to read about variables, functions and objects all over again when you are trying to know more about the Registry pattern, for example. It's hard to research on the net for this, because my question itself seems vague and difficult to formulate into a single search query. I need people-advice - what do you do in this situation?
