  • Will Xubuntu 12.10 also have amazon ads?

    - by Miguel Guasch
    and thanks in advance for your comments: I'm currently using Ubuntu 12.04, and quite happy with it. I'm using the Unity desktop, and I've got no major complaints. My problem/question is: I've been reading on the news, forums, and different websites that the new version in 12.10, which i'll eventually have to upgrade to if I plan on using Ubuntu, has a lens/amazon function on the dash that sends queries to amazon. Now, this disturbs me a bit, since I don't want to see "shopping recommendations" everytime I look for something, be they from amazon or from "future partners". Does this new "function" only apply to the Unity desktop? If I switch to the Xfce desktop, will I be able to "save myself" from sending search data to amazon and/or shopping recommendations from them? Or will I have to entirely switch distributions, in order to evade this? Again, many thanks in advance for your comments and/or help. Regards, Miguel.

  • Kinetic Scroll in Maverick

    - by Shoaib
    I have Sony VAIO FW 230J laptop. I was using Lucid and upgraded my system to Maverick beta in September 2010. Although there were few issues with beta release on my system although I did not felt myself in any deadlock. The most notable experience on my ubuntu was the smooth and kinetic scrolling and very sensitive touch pad experience with finer control that was oddly normal in previous releases and even on windows 7 currently. Definitely this release of ubuntu is improved for touch UI experience. I believe that this is magic of 10.10. For my official system I waited until the final release was out. After installing (upgrading) official system to Maverick I am not feeling the same smooth and kinetic scroll experience. My laptop has Graphics: Intel DMA-X4500MHD while my official desktop has Graphics: Intel DMA-X4500HD Do I need to install or update some software package to have similar kinetic scroll experience?

  • Java - learning / migrating fast

    - by Yippie-Kai-Yay
    Hello! This is not one of those questions like "How do I learn Java extremely fast, I know nothing about programming, but I heard Java is cool, yo". I have an interview for a Java Software Developer in a couple of weeks and the thing is that I think that I know C++ really good and I am somewhat good at C# (like, here I can probably answer on a lot of questions related to these languages), but I have almost zero experience with Java. I have a lot of projects written in both languages, I participiated in several open-source projects (mostly C++, though). Now, what should I do (in your opinion) to prepare myself for this Java interview. I guess migrating from C# to Java should be kind of fast, especially when you know a lot about programming in global, patterns, modern techniques and have a lot of practical experience behind you. But still two weeks is obviously not enough to get Java in-depth - so what should I focus on to have the best chances to pass the interview? Thank you.

  • How to learn programming for a medium scale project form a beginner? [closed]

    - by Lin Xiangyu
    I study programming by myself.I have learn servel programming languages. but I never write a project more than 1000 lines. I know the best way to improve programming skills is practise. The problem is many books, just talk about the programming language, or talk about build a project from a high level. Fews of books will teach how to build a middle scale project. For example, I want to build a simple HTTP Server(Nor like Apache or just a simple listenr to a port), a Markdown Parser, or a download tools just like emule or wget. I don't know what to do. I may found peaces of code in the web, or found familiar project in the Github. I don't know how to read the code. I want to some tutorial that can told me how to build the project step by step, teacher me how to write thousands lines of code. Any suggest?

  • Rendering performance in FlasCC + UDK when compared to Stage3d and UDK on Windows?

    - by Arthur Wulf White
    Adobe recently released the Flash C++ Compiler, which UDK uses to target Flash Player. Developers can now access UDK for browser applications. Does this mean greater performance than using a Stage3D engine (Away3D 4) and how much of a noticeable difference in performance would it make in rendering speeds? Is there any benchmark you could propose that would allow to compare them fairly? I am asking this to help myself understand the consequences in performance for deciding to use UDK in a browser based game. I would also like to know how it compares with UDK running natively in Windows? I am not asking which technology to use or which is better. Only interested in optimizing rendering speed in a 3d browser game with flash.

  • cannot use sudo on ubuntu server passwordless authentication?

    - by Lucas Crijns
    Hello I'm new at the forum and I want to introduce myself: I'm Lucas Crijns and I'm a very happy user of ubuntu server. I was reading about passwordless authentication with ssh. So I made a key and published it to ubuntu server, it worked well and I could login with my private key. But then I locked the account to prevent hacking from my password. After I ran "passwd -l lucas", I was not longer able by my next login to use sudo. Because it was asking for a password and I locked it. I was thinking that sudo would also be without a password. My question is now: is it possible to use sudo? And how can I enable it without a valid password for sudo? Thank you for your help!

  • Feeling a bit... under-challenged in my university course

    - by Corey
    I'm currently a sophomore at my university, majoring in Computer Science. Obviously, there are some programming courses as part of my curriculum. However, I'm feeling very underwhelmed by its progress. I've self-taught myself a lot and like to code in my spare time as a hobby. I'm currently in Computer Science II. I never took CS 1 because it seemed rather basic -- I asked someone in the department if they would override my CS 1 requirement if I passed their final (which I did with flying colors). Anyway, the class is going by quite slowly. It seems like the rest of the class has a hard time understanding some basic concepts, which the professor needs to keep going over to help them understand. Is this normal? Looking at the class schedule, I seem to know everything except for one or two things near the very end of the semester. Is there a different perspective I can look at this through so it doesn't seem so boring?

  • Improving without mentor

    - by speeder
    Although I consider myself not much experienced, I keep landing in jobs as the leader somehow (in the current one I am tech director of the company, in a previous one I was the R&D head). I understand why this happen (I have a certain specific set of skills, and I use some uncommon programming languages), my issue is: I cannot find a mentor... I know there must be stuff to me learn, and I notice as I work over the years that I am slowly learning more and more, but I believe that there are some way to get better much faster than just coding... So, how I improve when there are no other person in the company to teach me, or to me read their code? (or fix their code even...) I think I am beyond books, but way below a "master" level, so I don't know where to learn more.

  • What is involved for a simple UDP game?

    - by acidzombie24
    I once tried to write a simple game with UDP in a week as a throwaway test. It went horribly. I threw it away early. The main problem i had was restoring the game state of all players/enemies/objects to an old state and fast forward the game to the point of time the player is playing (ie half a second before a jump. A little early or late can make the player miss the jump) Maybe this method is not the easiest way? i suspect it to be but i designed it wrong from the beginning and realized at the end of 2nd day. (so i didnt learn too much or wasted that much time) For myself and others, What is involved for a simple UDP game and how do i write one? Or how do i solve the prediction problem restoring to state properly. I'll mark this as CW bc i know there will be lots of helpful answers.

  • What is the best drink to drink when you have read nonsense questions on programmers?

    - by stefan
    I am having a hard time deciding what drink to drink after I have read a nonsense question on programmers.stackexchange. It's either Beer och Whisky; The beer is nice since you can down it some what relaxed but some times I feel the need for something "stronger" because the question is so utterly nonsense and stupid. Every time I have read a stupid / nonsense question on programmers.stackexchange.com I've questioned myself why I didnt write some code instead. I couldve probably written countless lines of codes, together probably building a new Facebook or Linux by now. But instead I sacrificed my precious time reading questions that shouldn't have been posted on the internet. It really makes me frustrating, I guess that is why I am so often considering the whisky part instead of beer. Since beer will maybe not calm me down enough and then I have to take the whisky too, together it's a) slightly more expensive and b) more time consuming. So, what is the best drink?

  • Can an agile shop every really score 12 on the Joel Test? [closed]

    - by Simon
    Possible Duplicate: Can an agile shop every really score 12 on the Joel Test? I really like the Joel test, use it myself, and encourage my staff and interviewees to consider it carefully. However I don't think I can ever score more than 9 because a few points seem to contradict the Agile Manifesto, XP and TDD, which are the bedrocks of my world. Specifically the questions about schedule, specs, testers and quiet working conditions run counter to what we are trying to create and the values that we have adopted in being genuinely agile. So my question is whether it is possible for a true Agile shop to score 12? [Note: I had this question closed on meta so I have re-posted here]

  • Do I really need to "learn" C# for XNA if I know Java?

    - by CJ Sculti
    so I want to start developing in XNA. As of now, I do not know C#, but I would consider myself "good" at Java. I have looked at some C# code and it looks almost IDENTICAL to Java... After looking at this, http://www.harding.edu/fmccown/java_csharp_comparison.html it looks like they are basically the same. Obviously some function names are going to be different, but I think I can handle it. Now if I want to learn game development in XNA, do I really need to "learn" and master C#, or can I just jump right in and learn along the way? I should also mention, I also know PHP which looks very similar...

  • Why are part-time jobs in programming an anomality?

    - by Mikle
    I've recently quit my full time developing job at mega-corp, and I decided that I'll look for a part time job. Since then I've talked to half a dozen potential employers, and every one of them had the same reaction when I said the magic words "part-time" - they all closed up and became suspicious. Now, I understand that it might just be me, so as control I asked every one of them what if I were willing to work full time, and they all said I would probably get an offer. My question is two fold: Why, as an employer, would you give up a competent, even great, developer, simply because he wants to work 3 days a week and not 5? How do I sell the story of part time job better? I usually just list my reasons which are that I prefer that balance currently in my life and that I want to work on my own projects, but it leaves them even more suspicious - am I going to start something myself and quit? Am I just lazy?

  • What's special about currying or partial application?

    - by Vigneshwaran
    I've been reading articles on Functional programming everyday and been trying to apply some practices as much as possible. But I don't understand what is unique in currying or partial application. Take this Groovy code as an example: def mul = { a, b -> a * b } def tripler1 = mul.curry(3) def tripler2 = { mul(3, it) } I do not understand what is the difference between tripler1 and tripler2. Aren't they both the same? The 'currying' is supported in pure or partial functional languages like Groovy, Scala, Haskell etc. But I can do the same thing (left-curry, right-curry, n-curry or partial application) by simply creating another named or anonymous function or closure that will forward the parameters to the original function (like tripler2) in most languages (even C.) Am I missing something here? There are places where I can use currying and partial application in my Grails application but I am hesitating to do so because I'm asking myself "How's that different?" Please enlighten me.

  • Can I use DllImport/PInvoke in libraries loaded as Assets in Unity Free?

    - by sebf
    I am interested in using utilising third-party libraries in Unity Free. I know Unity can use managed libraries as Assets, but only the Pro version supports using native libraries. (DllImport within scripts). This thread however suggests that it is possible to import DLLs in the free version. I would like to utilise native libraries (as a hobbyist I cannot afford Pro), but want to do it the supported way so I don't have to worry about Unity 'fixing' this hole if that is what it is. Is there any supported way to use native libraries with Unity free? (i.e. does that thread suggest a workaround or is it a 'bug'? Is it supported to use DllImport/PInvoke in libraries loaded as assets? (could I create a wrapper myself?)

  • is it better to spend my free time mastering a language I work with or learning a new one?

    - by edthethird
    I work full time on an android project and am very comfortable with both java and the android framework. On a good day, I would rate my abilities at an 8, and maybe a 7 on a bad day. I've recently found myself with more free time then I'm used too, so I have been working on a lot of personal projects. I am beginning to wonder what others think about this; is it worth my time to continue experimenting and pushing Android, or would I be better off learning another language? What do you all think about this? What would you do with more free time and energy than you know what to do with?

  • 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?

  • 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

  • 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.

  • Developing a php system that tracks other websites analytics

    - by CodeCrack
    I want to develop a PHP website feature where users sign up, get a javascript snippet code that display an image on their site, and let's me track the number of visitors, unique hits, clicks and average visitor duration on their page. Is that something that should be done with some open source analytic software such as http://piwik.org/ or it's pretty doable on your own? If I had to do it myself from scratch, I would use image/pixel as a way to track the visit, drop a cookie with javascript snippet to track uniques, track clicks based on image click and redirect, and not sure about the bounce rate. Any thoughts or opinions are welcome.

  • Junior software developer - How to understand web aplications in depth?

    - by nat_gr
    I am currently a junior developer in web applications and specifically in asp.net mvc technology. My problem is that the c# senior developer in the company has no experience with this technology and I try to learn without any guidance. I went through all tutorials (e.g music store), codeplex projects and also read pro asp.net mvc 4. However, most of the examples are about crud and e-commerce applications. What I don't understand is how dependency injection fits in web applications (I have realized that is not only used for facilitating unit testing) or when i should use a custom model binder or how to model the business logic when there is already a database schema in place. I read the forum quite often and it would very helpful if some experienced developers could give me an insight about how to proceed. Do I need to read some books to understand the overall idea behind web applications? And what kind of application should I start building myself - I don't think it would be useful to create similar examples with the tutorials.

  • Learning Python from Beginner to Advanced level

    - by Christofer Bogaso
    I have some problems in my hand and would like to resolve them by myself (rather than hiring some professional, obviously due to cash problem!): build a really good website (planning to set-up my own start-up). build some good software (preferrably with exe installation files) on many mathematical and statistical techniques. To accomplish those tasks, is it worth to learn Python in advance level? I have advanced programming experiences with R and Matlab and VBA (and some sort of C), however not anything on Python. Be very grateful if experts put some guidance here. Thanks for your time.

  • Disqus-like comment server

    - by wxs
    Hi all, I'm looking at setting up a blog, and I think I want to go the static website compiler route, rather than the perhaps more conventional Wordpress route. I'm looking at using blogofile, but could use jekyll as well. These tools recommend using disqus to embed a javascript comment widget on blog posts. I'd go that route, but I'd rather host the comments myself, rather than use a third party. I could certainly write my own dirt-simple comment server, but I was wondering if anyone knew of one that already exists (of the open source variety). Thanks!

  • Simulating simultaneous entities

    - by Steven Jeuris
    Consider the need to simulate a set of entitities in an accurate way. All entities exist in an artificial timeline. Within 'steps' of this timeline, all entities can do certain operations. It is imperative that timed events, are handled accurately, and not in processing order. So simple threading isn't a proper simulation, nor is procedurally walking across all entities. Processing may be slow, accuracy is key here. I have some ideas how to implement this myself, but most likely something like this has been done before. Are there any frameworks available for these purposes? Is there any particular paradigm more suitable?
