  • How to disable laptop internal keyboard

    - by Abhijit Navale
    I am using external usb keyboard. I want to disable laptop's internal keyboard using software. I know that i can just remove the internal keyboards wire and disconnect it physically, but i wanted to disable it using software so that later I can enable it by just executing a command in terminal easily. I am talking about disabling the keyboard and NOT the keyboard layout. I am having Hp-Compaq Presario A965 TU Laptop Intel Centrino Core 2 Duo(Freq. 2 GHz). I am using 64 bit Ubuntu Lucid Lynx.

  • How do I install Java?

    - by Jay
    I am using Ubuntu 11.04 Natty Narwhal. I recently installed openjdk-jre6 because one of the websites I use requires java for me to log in. Unfortunately, even after installing openjdk-jre6, I am not able to use the website. In place of 2 text boxes where I am supposed to enter my username and password, it simply shows a message "click here to download plugin". I am using Firefox by the way. I even tried to install java by clicking on that message. But it says "Java Runtime Environment not available". And then gives me a button to install java manually. But I would rather install it from the repo's. Could someone please tell me, what I should do to get Firefox to take note of the openjdk-jre6 that I have already installed?

  • Error installing Windows7 64 bits on VirtualBox

    - by MetaDark
    I am trying to set up Windows in Virtual Box, so I don't need to reboot in the rare occasion that I actually need it. The problem is, Virtual Box doesn't preform any errors when I insert the 32bit installation CD but when I try to use the 64bit installation; What!? I am already using the installation disc! I've checked my BIOS to see if I have SVM (AMD's version of VT) disabled and all I see is "Enabled" I have a K9N6PGM2-V2 motherboard A Triple Core AMD Athlon II A Nvdia NForce 430 integrated graphics card 4GB of RAM An 80GB IDE And a 1TB SATA I don't think the last three specifications matter but just in case XP I am pretty sure the CD isn't broken ( I am going to make sure in just a moment ), what could be the cause to this problem? Edit: The 64bit installation CD is not broken, but I found out when trying to install from the 32bit version that it's trying to upgrade, not preform a fresh install - Odd.

  • Effectiveness and Efficiency

    - by Daniel Moth
    In the professional environment, i.e. at work, I am always seeking personal growth and to be challenged. The result is that my assignments, my work list, my tasks, my goals, my commitments, my [insert whatever word resonates with you] keep growing (in scope and desired impact). Which in turn means I have to keep finding new ways to deliver more value, while not falling into the trap of working more hours. To do that I continuously evaluate both my effectiveness and my efficiency. EFFECTIVENESS The first thing I check is my effectiveness: Am I doing the right things? Am I focusing too much on unimportant things? Am I spending more time doing stuff that is important to my team/org/division/business/company, or am I spending it on stuff that is important to me and that I enjoy doing? Am I valuing activities that maybe I have outgrown and should be delegated to others who are at a stage I have surpassed (in Microsoft speak: is the work I am doing level appropriate or am I still operating at the previous level)? Notice how the answers to those questions change over time and due to certain events, so I have to remind myself to revisit them frequently. Events that force me to re-examine them are: change of role, change of team/org/etc, change of direction of team/org/etc, re-org, new hires on the team that take on some of the work I did, personal promotion, change of manager... and if none of those events has occurred since the last annual review, I ask myself those at each annual review anyway. If you think you are not being effective at work, make a list of the stuff that you do and start tracking where your time goes. In parallel, have a discussion with your manager about where they think your time should go. Ultimately your time is finite and hence it is your most precious investment, don't waste it. If your management doesn't value as highly what you spend your time on, then either convince your management, or stop spending your time on it, or find different management: Lead, Follow, or get out of the way! That's my view on effectiveness. You have to fix that before moving to being efficient, or you may end up being very efficient at stuff that nobody wants you to be doing in the first place. For example, you may be spending your time writing blog posts and becoming better and faster at it all the time. If your manager thinks that is not even part of your job description, you are wasting your time to satisfy your inner desires. Nobody can help you with your effectiveness other than your management chain and your management peers - they are the judges of it. EFFICIENCY The second thing I check is my efficiency: Am I doing things right? For me, doing things right means that I deliver the same quality of work faster [than what I used to, and than my peers, and than expected of me]. The result is that I can achieve more [than what I used to, and than my peers, and than expected of me]. Notice how the efficiency goal is a more portable one. If, by whatever criteria, you think you are the best at [insert your own skill here], this can change at two events: because you have new colleagues (who are potentially better than your older ones), and it can change with a change of manager (who has potentially higher expectations). That's about it. Once you are efficient at something, you carry that with you... All you need to really be doing here is, when taking on new kinds of work that you haven't done before, try a few approaches and devise a system so that you can become efficient at this new activity too... Just keep "collecting" stuff that you are efficient at. If you think you are not being efficient at something, break it down: What are the steps you take to complete that task? How long do you spend on each step? Talk to others about what steps they take, to see if you can optimize some steps away or trade them for better steps, or just learn how to complete a step faster. Have a system for every task you take so that you can have repeatable success. That's my view on efficiency. You have to fix it so that you can free up time to do more. When you plan a route from A to B - all else being equal - you try to get there as fast as possible so why would you not want to do that with your everyday work? For example, imagine you are inefficient at processing email: You spend more time than necessary dealing with email, and you still end up with dropped email threads and with slower response times than others. How can you improve? Talk to someone that you think is good at this, understand their system (e.g. here is my email processing system) and come up with one that works for you. Parting Thoughts Are you considered, by your colleagues and manager, an effective and efficient person at your workplace? If you are, what would you change if you were asked by your management to do the job of two people? Seriously, think about that! Your immediate reaction may be "that is not possible", but it actually is. You just have to re-assess what things that were previously important will now stop being important, by discussing them with your management and reaching agreement on relative priorities. For example, stuff that was previously on your plate may now have to be delegated or dropped. Where you thought you were efficient, maybe now you have to find an even faster path to completion, perhaps keeping in mind that Perfect is the Enemy of “Good Enough”. My personal experience (from both observing others and from my own reflection) is that when folks are struggling to keep up at work it is because of two reasons: They are investing energy in stuff that they enjoy doing which the business regards as having a lower priority than a lot of other things on their plate. They are completing tasks to a level of higher quality than what is required (due to personal pride) missing the big picture which almost always mandates completing three tasks at good enough quality than knocking only one of them out of the park while the other two come in late or not at all. There is a lot of content on the web, so I strongly encourage you to use your favorite search engine to read other views on effectiveness and efficiency (Bing, Google). Comments about this post by Daniel Moth welcome at the original blog.

  • Can I become a Game Designer? [on hold]

    - by user32721
    This is my first time posting something on a forum in 4 years. I am posting this because I want to adjust my expectations and goals regarding game design. I am in college in Morocco (Al Akhawayn university). just started my junior year. I am a communications major (school of humanities) and a gender studies minor. I want to become a video game designer. It is the only career that I am interested in. I have been playing ever since I was 5 and haven't stopped yet. Currently I don't have any noteworthy skills to become a designer. I don't know how to program (don't really have the patience for it) and I can't draw to save my life. I haven't tried visual software like MAYA or MAX so I can't comment on graphic design. So I basically want to know whether my current education is capable of helping me reach my goal. If not then should I take a master's in game design (in the U.S?) or switch my minor to computer science? I am sorry that this post is long! I look forward to hearing your advice!

  • How to set-up a simple subversion workflow

    - by Milen Bilyanov
    I am trying to set-up a simple SVN workflow at home. I am new to subversion (and programming) so I have been reading the official PDF documentations but still not sure about how to set-up my repository. I am working mainly with python, bash and rsl (Renderman Shading Language) So I already have a /dev structure on my disk as this: http://imageshack.us/f/708/devstructure.png/ And I have a /site structure that links to my /dev folder: http://imageshack.us/f/651/sitestructure.png/ So obviously starting to use SVN will change this approach that I already have in place. The question is when I am setting-up my SVN repository for the work I do in my /dev folder: Will I set-up a separate repository for each different programming platform? and Where exactly I should be placing my repository? Thanks.

  • Google Closure Compiler - what does the name mean?

    - by mikez302
    I am curious about the Google Closure Compiler. Why did they name it that? Does it have anything to do with lexical closures? EDIT: I tried researching it in the FAQ and documentation, as well as doing Google searches such as "closure compiler name". I couldn't find anything definite, hence the reason I am asking. I don't think I will get a profoundly helpful answer but I was hoping that I could at least satisfy my curiosity. I am not trying to solve a specific problem. I am just curious.

  • Game Development In C Only. Is it possible?

    - by Ishan Sharma
    I am a first year college student in India and want to make a small game as a this semester project. I am quite good at C and am learning it rapidly but I wanted to ask if developing a game entirely in C(no C++ or C#m I'd love to use these but for college projects, we have strict requirements of using only C). What I am looking for is a simple top view driving game. It won't have anything fancy and even the visual things will be powered by simple characters. For example, user controlled car can be represented by ¦ and edges of road by series of |'s. What do you think?

  • How to use the float value from Noise function in voxel terrain?

    - by therealjohn
    Im using Unity, although this question is not really specific to that engine. Im also using an asset from the store called Coherent Noise. It has some neat noise functionality built it. I am using those functions to produce some noise values. I am getting a value between 0 and 1 (floats). I have an array of blocks (for minecraft like voxel terrain) and I am confused on how to use this float value for terrain? Do I do something like <= 0 == Solid block etc etc? I am confused on how to use the floating values that the noise functions produce to use for height values of an array of say a height of 16. Thanks for any guidance.

  • How do I tackle top down RPG movement?

    - by WarmWaffles
    I have a game that I am writing in Java. It is a top down RPG and I am trying to handle movement in the world. The world is largely procedural and I am having a difficult time tackling how to handle character movement around the world and render the changes to the screen. I have the world loaded in blocks which contains all the tiles. How do I tackle the character movement? I am stumped and can't figure out where I should go with it. EDIT: Well I was abstract with the issue at hand. Right now I can only think of rigidly sticking everything into a 2D array and saving the block ID and the player offset in the Block or I could just "float" everything and move about between tiles so to speak.

I am currently working on a project in my free-time a freetime which is mostly data centric and I would like to develop an eye-catchy interface for it using Silverlight. What I am looking for are examples of nice and interesting LOB applications in Siverlight without the use of paid frameworks. So far, I could only find something like Telerik sample application, but it uses a lot of Telerik controls I can't afford to buy.

  • why is glVertexAttribDivisor crashing?

    - by 2am
    I am trying to render some trees with instancing. This is rather weird, but before sleeping yesterday night, I checked the code, and it was in a running state, when I got up this morning, it is crashing when I am calling glVertexAttribDivisor I haven't changed any code since yesterday. Here is how I am sending data to GPU for instancing. glGenBuffers(1, &iVBO); glBindBuffer(GL_ARRAY_BUFFER, iVBO); glBufferData(GL_ARRAY_BUFFER, (ml_instance->i_positions.size()*sizeof(glm::vec4)) , NULL, GL_STATIC_DRAW); glBufferSubData(GL_ARRAY_BUFFER, 0, (ml_instance->i_positions.size()*sizeof(glm::vec4)), &ml_instance->i_positions[0]); And then in vertex specification-- glBindBuffer(GL_ARRAY_BUFFER, iVBO); glVertexAttribPointer(i_positions, 4, GL_FLOAT, GL_FALSE, 0, 0); glEnableVertexAttribArray(i_positions); glVertexAttribDivisor(i_positions,1); // **THIS IS WHERE THE PROGRAM CRASHES** glDrawElementsInstanced(GL_TRIANGLES, indices.size(), GL_UNSIGNED_INT, 0,TREES_INSTANCE_COUNT); I have checked ml_instance->i_positions, it has all the data that needs to render. I have checked the value of i_positions in vertex shader, it is the same as whatever I have defined there. I am little out of ideas here, everything looks pretty much fine. What am I missing?

  • Is ActionScript 3 used by Serious Indie Developers?

    - by Puedes
    This question is for dedicated independent game developers: My dream is to be a game developer. I am a senior in high school who has taken Computer Science for all four years. I have used Java the whole time, but last year I started using PHP and ActionScript 3 (with Flixel). I also used Game Maker for a brief period. I apologize for this, I wanted to get that out of the way and clarify the fact that I have experience of some kind with game development. I am stuck at the moment because I don't quite know what language to use to develop games at a professional level. I am seriously interested in becoming a dedicated game developer, but this issue is really bothering me. I would like to know what the best option would be for my case, based on your experiences. Any advice is appreciated. Things to consider: I am only interested in making 2D games (I am not worried about 3D support) It would be ideal to use something that can be ported to multiple platforms (so as not to run into this problem later) I can't seem to figure out what the industry likes to use So far, this is what I have: I can't decide if it would be wise to stick with ActionScript 3, or move to C++ I know Flash would be for browser games, but what if I want to make a downloadable game, like Plants Vs. Zombies or Super Crate Box? Would Flash be a smart choice for standalone games, or did they use something else? Thank you for reading this, as I would like to stop worrying about this and make some games! Also, I hope this wasn't all over the place :) tl;dr Should I move ahead with AS3 or use something else i.e. C++

  • Which programming language could I use for Natural Language Processing to extract clinical words?

    - by MACEE
    I am going to do entity extraction (like Named Entity Recognition) from clinical free text (unstructured raw text such as discharge summaries) and these entities could be any medical problem, medical tests or treatments. I am going to use one of i2b2 datasets (https://www.i2b2.org/) if case you are familiar with that. I am new to the NLP(Natural Language Processing) field and I need a programming language to support NLP tasks and also easily connect to the available libraries of machine learning algorithms like CRF. I don't know much java and I heard about Python, Perl and Scala but I am not sure which one would be the best option for this task?

  • Masters for Artificial Intelligence

    - by Frenchie
    I am very interested in going to graduate school to study Artificial Intelligence. I am currently an undergrad student majoring in Computer Science, I will be finished in a year and a half so I figured now is a good time to start looking. I do not have a competitive GPA(3.3) so I am not looking for the top 25 graduate schools in AI such as listed in this ranking. So far I am taking into consideration the University of Georgia, they have a masters in AI, separate from a masters in CS. If you know of any other schools that has a decent masters in CS with an emphasis on AI or a masters in AI by itself please let me know. Thank you. USA/Canada schools only.

  • Reconstruct a file from a TCP stream

    - by Abhishek Chanda
    I have a client and a server and a third box which sees all packets from the server to the client (but not the other way around). Now when the client requests a file from the server (over HTTP), the third box sees the response. I am trying to reconstruct the file there. I am using libpcap to capture TCP datagrams and trying to reconstruct the file there. Here is what I did Listen for packets on an interface Group all packets which have the same ACK number Sort the group based on SEQ number Extract data from each packet and combine them and write to the disk The problem is, the file thus generated is not exactly the same as the original file. Does everything sound correct here? Some more details: I am using C++ The packet data is being stored as std::vector<char> I did change the byte order while reading the ack number and seq number from the packet using ntohl I am not sure if I need to change the byte order for the data as well. I tried to reverse the data from each packet before combining them, even that did not work. Is there something I am missing?

  • MS in Computer Science after BE in electronics

    - by Abhinav
    I am doing my 3rd year Bachelors in Electronics and Electrical Communication but from the first year I have been interested in Computer Science. But at that time it was just my hobby. But in second year when I joined robotics my love for computer science rose. I with my team came in top three in 2 National Competition (Technical fests of different IITs) where we used Image Processing, Hardware interfacing etc. But then I realised that Computer Science is not just about coding. I took many lectures from online free schools like Udacity, Coursera in subjects related to Artificial Intelligence, Building a Search Engine, Design and Analysis of Algorithm, Programming a Robotic Car, Programming Languages, Machine Learning, Software Engineering as a Service, WebApps Engineering, Compilers, Applied Crypotography etc. I also did some courses in Core and Advanced Java in my second year from training institute. I will also be taking course in Statistics, Databases, Discrete Mathematics from 25th June. Now I realized how vast is the field of Computer Science and how efficient you become on deciding algorithms and classifying problems into different subfields which have been thoroughly researched so you don't always do brute force thing or naive programming. Now this field has become kind of passion for me. Adding to the fact I am also doing my 6 months internship in software field in Texas Instruments where I am working on Automation and Algorithms. I also have some 5-6 good college level projects in Softwares and Robotics. I also like Electronics but only some fields like Operating System(this subject was there in Electronics also), Micro Processor, Digital, Computer Architecture, DSPs etc. I really want to pursue MS in some field of Computer Science. I am giving GRE in October/November. Till now I have good CG of around 9.4/10 and my 1 year in college is still left. Do I have any chance that some good University in US will consider me for MS in field related to computer science or Robotics. Also Can you suggest somethings that I can do during this 1 year to increase my chances for MS or should I apply for EECS(Electrical Engineering and Computer Science) and then I can shift more towards Computer Science as my major option. My main aim is to do Phd after Ms in CS if I am able to do that somehow. I know that I have to put much extra effort to understand things in MS than CS undergraduates but I will do that with my full dedication, also when I communicate with my college CS students or during my internship period I didn't feel that I am missing very much stuff that they know and was very comfortable during my internship with software employees.
