  • Everything turning black when pitching down

    - by Gordon
    Just a quick questions about something that's occurring in my world. Every time I pitch my camera downward, everything starts turning black, and if I pitch upward, everything sort of intensifies. I'm multiplying my normals by the normal matrix in the shader, and I'm multiplying my lights direction by the model view matrix. If I leave the normal and light dir in world space everything ends up fine. I thought putting them both in view space would not cause those weird things to happen?

  • Should you document everything or just most?

    - by TheLQ
    It seems a bit of a controversial subject to document everything, including the "JavaBean" syntax of getters and setters for fields: People say its needlessly long and repetitive breaking DRY (don't repeat yourself), that the naming convention should explain everything, and it clutters code/documentation. Sometimes those arguments work. But other times, you end up with this: Above is common to open source projects that do boldly follow those principles. Your left with entirely useless documentation. That doesn't explain anything about whats going on underneath, the possible effects, or even what the expected value is (could it be null or never null? I don't know, the Javadoc doesn't tell me). So when should I document? Do I document everything even if it occasionally clutters code? Or do I document nothing since in my eyes its "obvious"?

  • Framework for Everything - Where to begin? [Longer post]

    - by SquaredSoft
    Back story of this question, feel free to skip down for the specific question Hello, I've been very interested in the idea of abstract programming the last few years. I've made about 30 attempts at creating a piece of software that is capable of almost anything you throw at it. I've undertook some attempts at this that have taken upwards of a year, while getting close, never releasing it beyond my compiler. This has been something I've always tried wrapping my head around, and something is always missing. With the title, I'm sure you're assuming, "Yes of course you noob! You can't account for everything!" To which I have to reply, "Why not?" To give you some background into what I'm talking about, this all started with doing maybe a shade of gray hat SEO software. I found myself constantly having to create similar, but slightly different sets of code. I've gone through as many iterations of way to communicate on http as the universe has particles. "How many times am I going to have to write this multi-threaded class?" is something I found myself asking a lot. Sure, I could create a class library, and just work with that, but I always felt I could optimize what I had, which often was a large undertaking and typically involved frequent use of the CRTL+A keyboard shortcut, mixed with the delete button. It dawned on me that it was time to invest in a plugin system. This would allow me to simply add snippets of code. as time went on, and I could subversion stuff out, and distribute small chunks of code, rather than something that encompasses only a specific function or design. This comes with its own complexity, of course, and by the time I had finished the software scope for this addition, it hit me that I would want to add to everything in the software, not just a new http method, or automation code for a specific website. Great, we're getting more abstract. However, the software that I have in my mind comes down to a quite a few questions regarding its execution. I have to have some parameters to what I am going to do. After writing what the perfect software would do in my mind, I came up with this as a list of requirements: Should be able to use networking A "Macro" or "Expression system" which would allow people to do something like : =First(=ParseToList(=GetUrl("http://www.google.com?q=helloworld!"), Template.Google)) Multithreaded Able to add UI elements through some type of XML -- People can make their own addons etc. Can use third party API through the plugins, such as Microsoft CRM, Exchange, etc. This would allow the software to essentially be used for everything. Really, any task you wish to automate, in a simple way. Making the UI was as also extremely hard. How do you do all of this? Its very difficult. So my question: With so many attempts at this, I'm out of ideas how to successfully complete this. I have a very specific idea in my mind, but I keep failing to execute it. I'm a self taught programmer. I've been doing it for years, and work professionally in it, but I've never encountered something that would be as complex and in-depth as a system which essentially does everything. Where would you start? What are the best practices for design? How can I avoid constantly having to go back and optimize my software. What can I do to generalize this and draw everything out to completion. These are things I struggle with. P.s., I'm using c# as my main language. I feel like in this example, I might be hitting the outer limit of the language, although, I don't know if that is the case, or if I'm just a bad programmer. Thanks for your time.

  • Mouse selects everything on its own

    - by meneer
    I have a strange problem that my mouse keeps selecting everything I point to. For example, if I open Rhythmbox, then at the top of the screen there is a text which says which song is playing. If I move my mouse over this text, then it will select this text; but I am not clicking. This behaviour does not happen in all programs. For example in Firefox I have no problem at all. Maybe it is Gtk related? Nautilus also behaves strangely; I cannot open files by clicking on them, I have to select and make a box around the file and then press enter to open it. If I click, then nothing happens. Similar problems also happen with other Gtk software. I think the problem might be related to touchscreen issues (I have a touchscreen). I run Gnome 3 on Ubuntu 12.04. I have a HP touchsmart 610 desktop computer. Any help is greatly appreciated. UPDATE: I just did a fresh reinstall, and I am 90% certain that it is related to the touchscreen drivers. Here is what happens when I reinstall. At first boot, so exactly after install, everything works fine, except the touchscreen: The touchscreen does not respond. I update ubuntu, because I installed from an old CD (CD with ub. 12.04). Then on next reboot I have touchscreen working , but the working touchscreen comes together with the mouse selecting everything on its own. SECOND QUESTION: Would anybody know how I could figure out what those touchscreen drivers are (so that I can disable them) ?

  • In the Cloud, Everything Costs Money

    - by BuckWoody
    I’ve been teaching my daughter about budgeting. I’ve explained that most of the time the money coming in is from only one or two sources – and you can only change that from time to time. The money going out, however, is to many locations, and it changes all the time. She’s made a simple debits and credits spreadsheet, and I’m having her research each part of the budget. Her eyes grow wide when she finds out everything has a cost – the house, gas for the lawnmower, dishes, water for showers, food, electricity to run the fridge, a new fridge when that one breaks, everything has a cost. She asked me “how do you pay for all this?” It’s a sentiment many adults have looking at their own budgets – and one reason that some folks don’t even make a budget. It’s hard to face up to the realities of how much it costs to do what we want to do. When we design a computing solution, it’s interesting to set up a similar budget, because we don’t always consider all of the costs associated with it. I’ve seen design sessions where the new software or servers are considered, but the “sunk” costs of personnel, networking, maintenance, increased storage, new sizes for backups and offsite storage and so on are not added in. They are already on premises, so they are assumed to be paid for already. When you move to a distributed architecture, you'll see more costs directly reflected. Store something, pay for that storage. If the system is deployed and no one is using it, you’re still paying for it. As you watch those costs rise, you might be tempted to think that a distributed architecture costs more than an on-premises one. And you might be right – for some solutions. I’ve worked with a few clients where moving to a distributed architecture doesn’t make financial sense – so we didn’t implement it. I still designed the system in a distributed fashion, however, so that when it does make sense there isn’t much re-architecting to do. In other cases, however, if you consider all of the on-premises costs and compare those accurately to operating a system in the cloud, the distributed system is much cheaper. Again, I never recommend that you take a “here-or-there-only” mentality – I think a hybrid distributed system is usually best – but each solution is different. There simply is no “one size fits all” to architecting a solution. As you design your solution, cost out each element. You might find that using a hybrid approach saves you money in one design and not in another. It’s a brave new world indeed. So yes, in the cloud, everything costs money. But an on-premises solution also costs money – it’s just that “dad” (the company) is paying for it and we don’t always see it. When we go out on our own in the cloud, we need to ensure that we consider all of the costs.

  • "sudo apt -get install foo-" causes removing foo package and everything depends on it

    - by M.Elmi
    While working in command prompt, I accidentally typed following command: sudo apt-get install python3- and ubuntu started removing python3 and everything depends on it (including firefox and much more). Fortunately I closed that terminal immediately and reverted everything by checking dpkg log file, but I was wondering why an install command should act like remove? Is it a bug? Consider the situation that you are looking for a package name (pressing Tab twice) and going through possibilities by pressing Enter key and those Enter keys remain in the keyboard buffer and.... youhaaaa... apt-get is removing the entire installation in front of your eyes.

  • Sound issues after trying everything

    - by Lerp
    I cannot get my sound working properly, no matter what I do, there's always some problem. It's very annoying as it's the only thing preventing me from making Ubuntu my main OS. At the moment my sound always plays through both my speakers and my headphones regardless except the sound through the headphones is crackly. It is also a bit quiet even though everything is maxed. I've managed to improve the situation to a point where the sound out of my speakers is perfect but I have none at all from my headphones. I do have two connectors listed in the sound settings but regardless of which one is selected it always plays through the speakers. I think this might have something to do with the fact that my speakers are plugging into the front of my computer, typically the headphone jack, and my headphones are plugging into the back but when I try disconnecting the speakers from the front there is still no sound from the headphones. I fixed the speaker sound by going through the sound settings and making sure they were all set to 100% then rebooting. Things I have tried: Maxing everything and unmuting everything in alsamixer Uninstalling pulseaudio Making gstreamer use only alsa via gstreamer-properties. This worked with the sound test button including independent sound between headphones and speakers but when I reset the computer it no longer worked. So I tried setting it manually in gconf-editor which didn't work either. Reinstalling alsa and pulseaudio Setting the model in /etc/modprobe.d/alsa-base.conf to 6stack and 6stack-dig neither worked.

  • Design patterns: when to use and when to stop doing everything using patterns

    - by honeybadger
    This question arises due to comment of FredOverflow in my previous post. Design pattern used in projects I am quite confused by the comment. I know design pattern help in making code reusable and readable (may lack in efficiency a bit). But when to use design patterns and most importantly when to stop doing everything using patterns or carried away by it ? Any comments from you will be helpful. tagging programing languages too to cover broader audience.

  • Why Ultra-Low Power Computing Will Change Everything

    - by Tori Wieldt
    The ARM TechCon keynote "Why Ultra-Low Power Computing Will Change Everything" was anything but low-powered. The speaker, Dr. Johnathan Koomey, knows his subject: he is a Consulting Professor at Stanford University, worked for more than two decades at Lawrence Berkeley National Laboratory, and has been a visiting professor at Stanford University, Yale University, and UC Berkeley's Energy and Resources Group. His current focus is creating a standard (computations per kilowatt hour) and measuring computer energy consumption over time. The trends are impressive: energy consumption has halved every 1.5 years for the last 60 years. Battery life has made roughly a 10x improvement each decade since 1960. It's these improvements that have made laptops and cell phones possible. What does the future hold? Dr. Koomey said that in the past, the race by chip manufacturers was to create the fastest computer, but the priorities have now changed. New computers are tiny, smart, connected and cheap. "You can't underestimate the importance of a shift in industry focus from raw performance to power efficiency for mobile devices," he said. There is also a confluence of trends in computing, communications, sensors, and controls. The challenge is how to reduce the power requirements for these tiny devices. Alternate sources of power that are being explored are light, heat, motion, and even blood sugar. The University of Michigan has produced a miniature sensor that harnesses solar energy and could last for years without needing to be replaced. Also, the University of Washington has created a sensor that scavenges power from existing radio and TV signals.Specific devices designed for a purpose are much more efficient than general purpose computers. With all these sensors, instead of big data, developers should focus on nano-data, personalized information that will adjust the lights in a room, a machine, a variable sign, etc.Dr. Koomey showed some examples:The Proteus Digital Health Feedback System, an ingestible sensor that transmits when a patient has taken their medicine and is powered by their stomach juices. (Gives "powered by you" a whole new meaning!) Streetline Parking Systems, that provide real-time data about available parking spaces. The information can be sent to your phone or update parking signs around the city to point to areas with available spaces. Less driving around looking for parking spaces!The BigBelly trash system that uses solar power, compacts trash, and sends a text message when it is full. This dramatically reduces the number of times a truck has to come to pick up trash, freeing up resources and slashing fuel costs. This is a classic example of the efficiency of moving "bits not atoms." But researchers are approaching the physical limits of sensors, Dr. Kommey explained. With the current rate of technology improvement, they'll reach the three-atom transistor by 2041. Once they hit that wall, it will force a revolution they way we do computing. But wait, researchers at Purdue University and the University of New South Wales are both working on a reliable one-atom transistors! Other researchers are working on "approximate computing" that will reduce computing requirements drastically. So it's unclear where the wall actually is. In the meantime, as Dr. Koomey promised, ultra-low power computing will change everything.

  • HTG Explains: What “Everything Is a File” Means on Linux

    - by Chris Hoffman
    One of the defining features of Linux and other UNIX-like operating systems is that “everything is a file.” This is an oversimplification, but understanding what it means will help you understand how Linux works. Many things on Linux appear in your file system, but they aren’t actually files. They’re special files that represent hardware devices, system information, and other things — including a random number generator. These special files may be located in pseudo or virtual file systems such as /dev, which contains special files that represent devices, and /proc, which contains special files that represent system and process information.

  • Designing for mobile (aka designing for everything)

    - by ihaynes
    Last Saturday I went to 'Developer Developer Developer 10' on the Microsoft campus at Reading (UK). This is one of a series of regular events put on by the developer community for the developer community. The guys who organise these events put in a huge amount of time and effort into them and they are well worth getting to if you can.I enjoy these events because there's always something currently relevant but also I can get an insight into things I don't normally come across or work with.Having said that, it's web related things that always grab my attention and this year one of my favourite speakers, George Adamson, gave a session on 'Designing for mobile (aka designing for everything)'. This is a subject close to my heart and I've tried to put the argument forward myself on http://www.ew-resource.co.uk/mobile/ but George makes a far better job of it that I can.His slideshow from the session is available on http://www.slideshare.net/george.adamson and although you won't get his unique presentation style in the static slideshow, this is well worth watching if you have the time.

  • LibreOffice prints everything half size

    - by oldmankit
    Ever since I printed a document from Evince in landscape orientation, LibreOffice Calc / Writer refuses to print anything correctly. It is scaling everything by 0.5x and rotating it. To get the same effect, go to print - page layout tab - pages per sheet = 2. However, I don't want 2. I want 1. I have wizzed through all of the printing options a few times but can't get to the bottom of this. I've restarted my printer and computer several times. I have done sudo apt-get purge libreoffice* and reinstalled again. Still it will not print full size. (Of course I have checked that the page settings are set to A4 and portrait.) Update: this problem is specific to one printer only, to printing from within LibreOffice (Calc, Writer). With other printers / programs I have no problems.

  • Windows 8: Everything from design, build, and how to sell a Metro style app

    - by Thomas Mason
    For me, there are a lot of similarities between an application developed for Windows Phone and a Metro style app developed for Windows 8. A Windows Phone 7 application (rather than an XNA game) is built in .NET and XAML against a subset of the .NET framework and the application has a lifecycle which needs to be conscious of battery life and so is split out into foreground/background pieces. The application is sandboxed in terms of its interactions with the local device and is packaged with a manifest which describes those interactions. The app needs to be aware of network connectivity status and its work on the network is done asynchronously to preserve the user experience.The app is packaged and deployed to a Marketplace which the user browses to find the app, read reviews, perhaps purchase it and then install it and receive updates over time. Quite a lot of those statements are as true of a Windows 8 Metro style app as they are for a Windows Phone app and so a Windows Phone app developer already has a good head start when it comes to building Metro style apps for Windows 8. With that in mind, there is an event to help developers with a Windows Phone app in Marketplace to begin the process of looking at Windows 8 and whether you can get a quick win by bringing your Phone application onto Windows. The idea of the event was to provide a space where developers can get together over 2 days and take the time out to look at what it means to take their app from Windows Phone to Windows 8. Kicking off on Saturday 16th June at 10am, we are told they have plenty of power sockets, WiFi, whiteboards, drinks, pizza, games, prizes and some quiet space that you can work in. Including people on hand with Windows Phone and Windows 8 experience to help everything along the way. There will be an attendee-voted schedule of talks but we’ll keep these out of your way if you just want to get on and code. We’ll also provide information around submitting your app to the Windows Store If you have a Windows Phone app in Marketplace, now’s a great time to look at getting it onto Windows 8. Sign up. Bring your laptop. Bring your app. Bring Windows 8 and Visual Studio 11. And everyone will their best to help you get your app onto Windows 8. Location & Venue TBA but it will be in central London, accessible by major railway and underground transportation. Day 1 Saturday 16th June 10am – 9pm Day 2 Sunday 17th June 10am – 4pm

  • Space partitioning when everything is moving

    - by Roy T.
    Background Together with a friend I'm working on a 2D game that is set in space. To make it as immersive and interactive as possible we want there to be thousands of objects freely floating around, some clustered together, others adrift in empty space. Challenge To unburden the rendering and physics engine we need to implement some sort of spatial partitioning. There are two challenges we have to overcome. The first challenge is that everything is moving so reconstructing/updating the data structure has to be extremely cheap since it will have to be done every frame. The second challenge is the distribution of objects, as said before there might be clusters of objects together and vast bits of empty space and to make it even worse there is no boundary to space. Existing technologies I've looked at existing techniques like BSP-Trees, QuadTrees, kd-Trees and even R-Trees but as far as I can tell these data structures aren't a perfect fit since updating a lot of objects that have moved to other cells is relatively expensive. What I've tried I made the decision that I need a data structure that is more geared toward rapid insertion/update than on giving back the least amount of possible hits given a query. For that purpose I made the cells implicit so each object, given it's position, can calculate in which cell(s) it should be. Then I use a HashMap that maps cell-coordinates to an ArrayList (the contents of the cell). This works fairly well since there is no memory lost on 'empty' cells and its easy to calculate which cells to inspect. However creating all those ArrayLists (worst case N) is expensive and so is growing the HashMap a lot of times (although that is slightly mitigated by giving it a large initial capacity). Problem OK so this works but still isn't very fast. Now I can try to micro-optimize the JAVA code. However I'm not expecting too much of that since the profiler tells me that most time is spent in creating all those objects that I use to store the cells. I'm hoping that there are some other tricks/algorithms out there that make this a lot faster so here is what my ideal data structure looks like: The number one priority is fast updating/reconstructing of the entire data structure Its less important to finely divide the objects into equally sized bins, we can draw a few extra objects and do a few extra collision checks if that means that updating is a little bit faster Memory is not really important (PC game)
