• Java and what to do with it

  - by SterAllures

  I've been browsing through several websites and several topics on this website. Now I'm just a starting programmer and I want to make a good decision. From what I understand is that Java is used alot for server stuff, and web applets but not really for computer applications running on a client, it's also used for Android programming and several other mobiles. I'm really interested in Android programming, I really love to program for mobile devices, in this case Android because I really think it has a lot of potential and I don't like the iPhone. If I want to program on Android I have to learn Java (aside from Mono). but if my decision changes over the next couple of years I don't think Java is the right language to get a job that programs computer applications. I think I get a job where I have to program server stuff, rather than computer applications. That's why I think C# is a good choice. I can program for Windows Phone 7 (I hope that will get big). and I have the feeling C# is more widely used for computer applications. so I think C# is more versatile looking at Mobile programming and computer programming. Or am I totally wrong thinking this?

• Photoshop alternative with same keyboard shorcuts

  - by user292254

  tldr; Is there a program with the same keyboard shortcuts and/or user interface as PS. I know the "photoshop alternative" question has been asked so many times, but I feel this variant is worth the time to ask. I am a web designer and have been using PS daily on a windows or mac machine for about 10 years, but I do most of my development in linux. The only thing that has been keeping me from the full switch to linux is PS. I have tried many alternatives, including GIMP, but I feel the barrier to entry is too high for one reason and one reason only, the keyboard shortcuts. Over the years I have become very adept and quick in the use of PS because of keyboard shortcuts and muscle memory. I realize that many shortcuts can be customized, but many actions are just too different from PS. So my question is what programs are out there that are the closest to PS in keyboard shortcuts and interface. I don't care if I have to do a bunch of customization to get it as close as possible, but I just can't take too much time to learn a completely new workflow. Of course I realize that any software will take time and effort, I just want to make that time/effort as minimal as possible. Thanks in advance for your responses. edit I should tell you the most important features and workflow I use on a daily basis are, Smart objects, linked documents, save for web and devises.

• Costs/profit of/when starting an indie company

  - by Jack

  In short, I want to start a game company. I do not have much coding experience (just basic understanding and ability to write basic programs), any graphics design experience, any audio mixing experience, or whatever else technical. However, I do have a lot of ideas, great analytical skills and a very logical approach to life. I do not have any friends who are even remotely technical (or creative in regards to games for that matter). So now that we've cleared that up, my question is this: how much, minimally, would it cost me to start such a company? I know that a game could be developed in under half a year, which means it would have to operate for half a year prior, and that's assuming that the people working on the first project do their jobs good, don't leave game breaking bugs, a bunch of minor bugs, etc.. So how much would it cost me, and what would be the likely profit in half a year? I'm looking at minimal costs here, as to do it, I would have to sell my current apartment and buy a new, smaller one, pay taxes, and likely move to US/CA/UK to be closer to technologically advanced people (and be able to speak the language of course). EDIT: I'm looking at a small project for starters, not a huge AAA title.

• Pick Up BioShock and Bioshock 2 for Price of a Big Mac Meal

  - by Jason Fitzpatrick

  Pre-ordering just opened on the third-installment of the highly-acclaimed horror-survival game series BioShock, BioShock Infinite. As part of the pre-order promotions, you can pick up a bundled copy of BioShock and BioShock 2 for a song. For the unfamiliar, BioShock is an atmospheric first-person-shooter backed up by an incredible storyline set in the underwater utopian-turned-dystopian city of Rapture. BioShock 2 continues the story in Rapture and the upcoming release (Febuary 2013) of BioShock Infinite takes place in the same game universe but fifty years before the events of the first two installments. If that seems like the kind of game you could dig into, Amazon has the Windows-platform version of BioShock and BioShock 2 bundled together for a scant $7.49–81% off the Steam and general retail price. The best part about the promotion is you can either download the games from Amazon or, for those of you that use Steam, you can simply plug the game product key into Steam. You can read more about the both the original two games and the upcoming release at the official BioShock site.

• How did we get saddled with the (hierarchical) filesystem as the basic data structure?

  - by user1936

  I'm self-taught and I don't have a CS degree. The more I've been learning about data structure, the more I wonder, in this day and age, how are we still saddled with the filesystem, with directories and files, as the basic data storage structure on the OS? I understand the simplicity of it, but it seems nowadays that there could be more options available natively. As far as I'm aware, the only project to improve the basic functionality of the filesystem was ReiserFS, where you could tell what line of a file was changed by whom, and when. For instance, if I could have native tagging for files, where I could tag images, diagrams, word-processing documents, an entire code repository, all as belonging to a single project, that would really be helpful to me. Since I'm stuck in the filesystem paradigm, I know that I could put all those into a single folder/directory, but what if they already exist in disparate directories, and they need to stay there? I know there are programs out there that can do this, but why aren't they on the filesystem? Something that would be nice to have is some kind of relational feature in the filesystem, like you get with RDBMSes. I understand that that was supposed to be part of Vista/7, but that fell off the feature list too. Sure, any program can store a binary file and have any data structure it wants in it, by why couldn't the OS offer more complex ways of storing data, beyond the simple heirarchy of the filesystem?

• sharing life experience

  - by gcc

  I am a student of computer engineering. I have never done any programming before, and as you can understand, I don't know how to study it or how to make my own programs. My English is weak [edited for clarity - ed], and so if you don't like the choices I list, please feel free to provide others. How should I study? How should I learn programming languages? Study completely from a book. Don't study from a book, just try writing code. A mix of the two; study from a book, then try writing code. Study half the book, then write the code by hand on paper. Listed to the teacher, then try to solve general problems (those not from any specific chapter). I have send that question to stackoverflow before when I am at first year. Now, I want to construct webpage to guide fresh students by giving advise of yours and mines.Maybe, you wonder Why I want to construct webpage , I just want help the other student. I am giving a link to that question < http://stackoverflow.com/questions/3389465/how-should-i-study-programming-languagess If you have other advice, feel free.

• Dual Booting Windows 7 and Ubuntu 12.04. Partition Sizes?

  - by John F.

  I'm about to reinstall Windows, so I thought that I'd try Ubuntu out on a partition just for fun. My question is, how large should my partitions be for each of them? I know this various depending on what you use, so i'll give you a general idea of what I have, and what I have in mind. I'm currently running: Windows 7 Professional (64bit) RAM: 4GB CPU: 2.5Ghz Quad Core processor HDD: 500GB GPU: 1GB Nvidia GeForce I have around 130GB in Steam games, and some heavier applications like Photoshop CS6, Sony Vegas Pro 11. But other Applications I use are: Chrome Skype Dxtory Fraps OpenOffice BitTorrent and other assorted smaller programs. So, I was thinking that I would give my Windows partition about 150-200GB, my Ubuntu Partition around 20GB, and the rest to shared storage. I'm not really sure if I'd need more or less on Ubuntu, because I've never used it and I'm not really sure what kind of apps i'd be using over there. This would also be a clean install, so I'd be wiping my HDD, creating the Partitions in GParted, then installing Windows with Ubuntu following that. Any critique you could give me? Maybe explanations to what the /root, /boot and /home partitions I hear are about? Thanks in advanced if you actually read this lengthy thing! Any help is appreciated. (x

• View the Time & Date in Chrome When Hiding Your Taskbar

  - by Asian Angel

  Do you prefer keeping your Taskbar hidden but still need to keep watch on what time it is? Now you can keep track of the time without the Taskbar using the Date Today extension for Google Chrome. A Look at Date Today with Different Themes This extension does one thing and does it well…it provides you with an “active icon” clock that will let you view the time and date in two fashions. The first is by hovering your mouse over the “Toolbar Clock Button”… And the second is by clicking on the “Toolbar Clock Button” to view an enlarged version. Here you can see the extension in use with five different themes to get an idea of how it might look with the theme that you are currently using. It does stand out very nicely with brighter or darker colored themes. Conclusion While this extension is obviously not for everyone it will make a nice (and useful) addition to Chrome for those who prefer keeping their Taskbar hidden.

• Best practice for combining a Java Applet/ Android interface?

  - by Pearsonartphoto

  I'm working on an online game, which I am seriously considering writing a Java Applet for it. The game is not overly complex on the features. I'm considering at some point having at least 3 versions of the game, which include a Java stand alone, applet, and Android game. I know from Design Patterns that the best way to use differing things like buttons and the like is to use a Bridge interface, where I have a common template for the common buttons. However, I'm having a bit of difficulty understanding what to do about the following. I know that Android programs use an Activity structure, which I am well familiar with, and that Applets extend the Applet interface, which I am not as familiar with. I also know that a stand alone java program uses basically a main() function, which doesn't have much structure. I'm convinced that there should be a way to design a common design pattern between the two, but somehow I'm missing what that is exactly. What can I do to make the different frameworks work with as much common code as possible?

• Acer Aspire One 725 - missing graphic card driver for Radeon HD 6290?

  - by Melon

  Recently I bought an Acer Aspire One 725 Netbook and installed Ubuntu 12.10 on it. I bought it, because it can run HD movies and has Full HD on external VGA port. However, movies from youtube have a really slow framerate. If you open three tabs in Opera (for example g-mail, youtube and askubuntu) it gets really laggy. My suspicion is that the driver for graphic card is missing. When I check the System->Details->Graphics the driver is unknown. After running lspci | grep VGA I get this output: 00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Device 980a From what I see, I have a AMD C70 processor integrated with (or something similar) AMD Radeon HD 6290. Has anyone had the same problem? Do you know which drivers need to be installed for the graphics to work properly? On official Acer page there are only drivers for Win7 and Win8... Update: I have tried installing fglrx but I get the following error (either I don't have libraries or someone didn't make a clean build before release ;) /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c: In function ‘KCL_MEM_AllocLinearAddrInterval’: /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:2124:5: error: implicit declaration of function ‘do_mmap’ [-Werror=implicit-function-declaration] /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:2124:13: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c: In function ‘kasInitExecutionLevels’: /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:4159:5: error: ‘cpu_possible_map’ undeclared (first use in this function) /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:4159:5: note: each undeclared identifier is reported only once for each function it appears in /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:4159:5: warning: left-hand operand of comma expression has no effect [-Wunused-value] Update 2: After fixing the erros in compilation, ubuntu acts bizarre and unstable (no left icon panel, no upper panel, cannot run any programs, I only see desktop)

• What constitutes a programming language and how does one copyright a programming language?

  - by Yannbane

  I've decided to create a programming language of my own, mostly just for fun. However, I got interested in the legal aspect of it all. You can, for example, licence specific programs under specific terms. However, how do you go about licensing a language? Also, by that I don't just mean the implementation of the language (compiler & VM), but the standard itself. Is there something else to a programming language I'm missing? What I would like to achieve by such licensing: Make it completely FOSS (can a language even be FOSS, or is that the implementation that can be FOSS?) Establish myself as the author (can you legally be an author of a language? Or, again, just the implementation?) Make it so that anyone implementing my language would be required to attribute me (MIT-style. Please note that I do not have any hopes for anyone actually ever doing that though, I'm just learning.) I think that the solution would be to separately license the VM and the compiler for my language, as "the official implementation", and then license the design document as the language itself. What exactly am I missing here?

• Best way: restructure an existing Team Foundation Server (TFS) solution

  - by dhh

  In my department we are developing several smaller AddOns for some unified communication server. For versioning and distributed development we use a Team Foundation Server 2012. But: there is only one large TFS solution for all of our applications and libraries: Main Solution Applications App 1 App 2 App 3 Externals Libraries Lib 1 Lib 2 Tools The "Application" path contains all main applications. Those are not depending on each other, but they depend on the Libraries and Externals projects. The "Externals" path contains some external DLLs referenced in our Applications and Libraries. The Libraries path contains commonly used libs (UI templates, Helper classes, etc.). They do not depend on each other and they are referenced in the Libraries and the Tools projects. The Tools path contains some helper programs like setup helpers, update web services, etc. Now, there's some major points why I'd like to change this structure: We can't use server builds. It's uncomfortable to manage TFS scrum management with sprints, impediments, etc. with a solution structure like that. Every developer always has access to all projects in the solution. A complete build lasts too long if one accidentally hits [F6] in Visual Studio... What would you change in this solution? How would you break those projects into smaller Solutions, how should those solutions be structured. My first approach would be, to create one TFS project for each Application, Library and Tool. But how can I ensure that e.g. App 2 always contains the newest version of Lib 1? Do I have to monitor changes on Lib 1 and update App 2 manually as soon as the Lib changes? Or can I somehow force Visual Studio to always use the newest version of an external project somehow?

• What do I need to Mod a Unreal Engine 3 game?

  - by RoadSideWarrior

  what I am looking for is some advise making a mod for a certain game and how I would go about making it. The game I am talking about is Blacklight: Retribution and what I wan't to know is; Is it possible? And if so, what programs will I need? It is an online only game so I was unsure how plausible a mod would be for it. Plus I have never made a video game before, but I do like the game and I wanted to do some things with it. Additionally, this will be my first time making anything video game related so I would appreciate any advise. To expand a bit, I plan to add something simple at first. A mod that would let you spectate another player in the first person. Then I plan do something a bit more complex where I want to make so the game optionally always records you playing (in short intervals most likely or you would run quickly out of memory). After all that is done I would add items, armor, weapons, and maybe make a map or not I am not sure but this in a shell what I hope to do. I don't know much about these things but I am reading anything I can get my hands on. So if this is overly ambitious or just plain out not a possibility any advise on what I should look to instead will be welcomed warmly. Thank you.

• Necessary Infrastructure for large project with many components communicating through IPCs

  - by jluzwick

  I have a fairly in depth question which probably doesn't have an exact answer. As a software engineer, I am usually tasked with working on a program or project with minimal understanding of how other components or programs in the project interact with each other. When one program fails in a sea of multiple components and processes, what infrastructure elements are necessary to ensure that the problem can be accurately tracked to the violating application? More specifically, what infrastructure elements should be necessary for this large project and which are optional but very helpful. One such example I can think of is some form of a common logging infrastructure that allows for a developer or tester to easily browse through a log that contains numerous components for messages that might allude to the culprit program along with a "trail" of what happened before the issue occurred. I'm thinking of something similar to Androids alogcat tool. These necessary infrastructure elements should be language-agnostic. While these elements should be understood by all engineers on the team in question, which elements should be understood at great detail by the technical system engineers and what should the individual software engineers be responsible for adding to their tools to allow for such infrastructures to take hold? Please feel free to ask for clarification if something does not make sense as I understand this question is very broad and needs some refinement. I will refine as necessary from the answers and comments I receive. Thanks for any help!

• Turn O&M Operations into Optimized Projects with Oracle Primavera

  - by mark.kromer

  Oracle enterprise project portfolio management with Primavera is much more than optimizing project performance and eliminating project failure on new projects, capital programs, etc. A very common use case that we see is small-scale frequent and recurring projects based on on-going operations and maintenance. As opposed to assigning resources to various activities when you are building a new network infrastructure, for example, Oracle has teamed-up the Primavera and eBusiness Suite teams to provide direct integration for work orders from Oracle's Enterprise Asset Management (eAM) system to populate into Primavera P6 project schedules. So now that your network infrastructure build-out project is complete, planners and operations managers can use the world-class what-if and scheduling capabilities in Primavera tools to assign work orders, maximize resource utilization and to reuse templates for typical O&M operations in Primavera and share that back to the operations teams using eAM for maintenance. Also, large-scale maintenance operations related to large assets in the asset lifecycle will include phase-outs, shutdowns and turn-arounds which are classic maintenance projects, as opposed to building something new, that Oracle Primavera with Oracle e-Business Suite provides full coverage to optimize your ALM processes in your business. Read more about these new capabilities from Oracle in the ERP space from the Oracle eAM data sheet.

• C++ Succinctly now available!

  - by Michael B. McLaughlin

  Over the summer I worked with SyncFusion to create an eBook based off of my C# to C++ guide for their free Succinctly Series of eBooks. Today the result, C++ Succinctly, was published for download. It is a free (registration required; they make tools and libraries for .NET development so you might get an occasional email from them – I’ve been signed up for a few months and have had maybe 3 emails total so it’s not horrible super spam or anything ) and you can download it as a PDF or a Kindle .MOBI file (or both). I’m excited with how it turned out and enjoyed working with the people at SyncFusion. The book contains a total of 20 code samples, which you can download from BitBucket (there’s a link very early in the book). Almost all of the code is also inline in the book itself so that you don’t need to worry about flipping back and forth between your dev machine and your eReader (but if you want to try to understand a concept better, you can easily download the code, open it up in VS 2012, and play around with it to see what happens when you tinker with things). The code does require Visual Studio 2012 because of its expanded support for C++11 features and since I wrote all of the samples as Console programs for clarity and compactness, you will need a version that supports C++ desktop development (currently VS 2012 Pro, Premium, or Ultimate). Sometime this Fall, Microsoft will be releasing Visual Studio 2012 Express for Windows Desktop which should provide a free way to use the samples. That said, I tested all of the samples with MinGW and only the StorageDurationSample will not compile with it due to the thread-local storage code. If you comment that out then you can compile and run all the samples with MinGW (or using a recent version of GCC in a GNU/Linux environment, or any other C++ compiler that provides the same level of C++11 support that Visual Studio 2012 does). I hope it proves helpful to those of you who choose to check it out!

• Unity elements sometimes appear while full screen in Virtualbox - how to stop it?

  - by frumbert

  Launcher is great, and it helps me finds stuff. I have the latest release of 12. But when I'm full screen in VirtualBox running another operating system and I hit some key combination I haven't yet figured out, Unity suddenly grabs keyboard focus. It might be alt-tab, it might be left-control x. I have physically pulled both the windows key and FN key off my laptop because they get in the way, so it's probably not the windows key. You don't know the focus has been stolen because the full screen app (VirtualBox) is still full screen and the Unity element is in the background. But you're busy typing into a Unity box, not your foreground application. This is particularly annoying. In my screenshot (taken from a camera, because the built in screen capture program can't capture a screenshot containing the launcher...) the windows VM is the foreground application, but the "Run Command" entry box has come up and is capturing the keyboard: I would like a foreground full screen app to stay that way. Is there a way that I can keep Unity but only have it activate its elements (e.g. pop out with its search box) if I physically click a button, not type some random key combination that foreground applications can get confused about? Otherwise I can do without the launcher or other elements, because doing my actual work is more involved than just launching programs.

• System in low graphics, deleted linux, grub rescue, can't access windows

  - by First timer

  So I'm pretty new to Ubuntu but I managed to install it with no big problems on both my desktop and netbook. When I installed it on my brother's netbook everything went horribly wrong and now I fear the system is close to beyond repair. The problem was first that it said it did not have any space left (seemed ridiculous since it had a lot). Then Ubuntu began booting into a "System is running in low graphics mode error" which I then tried to fix, using all the tips I could find in here but nothing helped. I think the graphics error and lack of space might have been related but I can't be sure. Finally I gave up repairing Ubuntu and went for a reinstall. Shouldn't have done that! I read that I should simply open Ubuntu through a live usb and choose GParted to delete the Linux partitions so I did and rebooted accordingly. Next, I was to install Ubuntu but now I am only given the option to wipe the whole disk for Ubuntu, not install along with windows 7. If I access GParted I can still see the ntfs partitions that hold windows 7 (there are 2: one labeled RECOVERY and another labeled OS and boot) so why can't I access them? Btw. the OS and boot has a little red mark with a warning that 1 cluster is referenced to multiple times, don't know what that means. If I boot without the live usb I am sent directly into a grub rescue "black screen of the computer will follow no orders". Please, I know that the easiest might be to simply wipe the whole thing clean but there are important files and programs on windows 7. Is there a way to just access windows? It is a dell inspiron 1018 mini netbook, so I have no cd input and no windows 7 installation cd.

• What would be a good opensource software for graphing circles, circular regions, and regions bounded by curves and/or arcs?

  - by Michael Dykes

  Hullo all. I have just started s job with Chegg, and my 1st assignment has me writign solutions for Stewart's Essential Calculus. I am dealing with the chapter on multiple integration, and need a good open-source software that I can easily use to draw regions (domains) that would require multiple integrals: i.e. circular regions, portions of circles, regions bounded by curves and/or arcs, and at some point 3D pictures. In most of these cases, I am not working with an exact equation or perhaps need to draw the region bounded by r (radius) between 1 and 2, and the angle theta bounded between pi/4 and 3 pi/4. I am not too terribly familiar with programs like Corel Draw, but the documents I have from this company suggest Corel Draw. So I think I am looking for an open-source free program like Corel Draw or something similar. Any additional suggestions would also be appreciated. I know I can do most, if not all of this using TikZ, but the learning curve is a bit steep, and at the moment I an on a time constraint. Thanks.

• How to customize the initrd embedded in or coming with the kernel image

  - by STATUS_ACCESS_DENIED

  I would like to add some tools and not just kernel modules into the initrd (initramfs-based). Now I'm aware of how to unpack and how to pack the initrd with cpio and have even written a hook for /etc/initramfs-tools/hooks in the past to integrate a third-party kernel module. However, while the available script libraries seem to be geared towards the integration of modules, none of them seems to be for integration of other entities (in particular programs and their dependencies). What options do I have to automate the integration of some useful tools for recovery into the initrd? I'm talking about the "rescue" system that the system drops into if it is unable to mount the root drive given to it by the boot loader. Please note that I don't want the SquashFS approach as is used for Live-CDs because for the issue at hand it will be by far sufficient to include some relatively small tools that aid in recovery of the system (when it gets stuck in initrd and can't boot further). Also, the machines when they run into the issue that we have had in the past tend to boot into the rescue system, but there a few tools are missing to kick the system back on trail ...

• Create a system image in Windows 8

  - by Greg Low

  One of the things that I've just come to accept is that the designers of Windows 8 and I think very differently.It'll take a long time to convince me that shutting down the computer is a "setting". Even after using Windows 8 for quite a while now, I still find that I struggle nearly every day, just trying to do things that I previously knew how to do. That's just not a good thing.Today I decided to create a system image as I hadn't made one lately. I started in Control Panel looking for Backup options. That yielded nothing except programs that wanted to "Save backup copies of my files with file history". I thought "oh well, let's just try the new search options". I hit the Windows key and typed "Backup". No, nothing came up there either.I searched again all over the Control Panel options to no avail.So it was time to hit Google again. Once again, clearly lots of people used to know how to do this and have been trying to work out where this option went.The first trick is that there are a bunch of Control Panel options that don't appear in the Control Panel. In the address bar at the top, if you click on Control Panel, you'll find there is an option that says "All Control Panel Options". That is curious given that's where I thought I was when I opened Control Panel. No hint is given on that screen that there are a bunch of hidden options. None the less, I then checked out "all" the options.The option that you need to create a system image in Windows 8 turns out to be the "Windows 7 File Recovery" option that appears in this extended list. Why does it say "Windows 7" when it's for "Windows 8" as well and I'm running "Windows 8"? Why do I have to choose an option that says "File Recovery" to create a system image backup?<sigh>But at least I've recorded it here for the next time I forget where to find it.

• Pipe an infinite stream to internal loop?

  - by Sh3ljohn

  I've seen a lot of things about redirecting stdout to a TCP socket, but no real example of how to do it in practice, specifically when the output stream generated by the first "command" never ends. To talk about something concrete, let's take programs like servers that typically output their log endlessly to stdout (well, as long as they run). If you redirect the output to a log file on the disk, then this file is always open (therefore not readable by others?) and grows infinitely, which eventually is going to cause problems. This might be a nood question, but I don't know what it does or how to do it so. How to redirect the output of a command to the internal loop? I want to make sure that data is sent EVERY time something is written to stdout, and that the pipe won't wait for the command to end (never happens ideally!). Is that right? If 2 is true, is there a buffer system to send chunks of data once it reaches a certain size only? Could you give me concrete command line examples to do the above? Thanks in advance

• Fresh install of 64 bit 12.04 over 32 bit 11.10 alongside Windows 7

  I currently have Ubuntu 11.10 32 bit and Windows 7 dual boot in separate partitions. I am trying to do a fresh install of Ubuntu 12.04 64 bit (mistakenly installed the 32 bit 11.10 a little while ago.. I need a 64 bit version to support AOSP build) OVER my the exisiting 11.10 partition. I have referenced How to Install fresh 12.04 install to a PC with dual booting Windows 7 & Ubuntu11.10?, as well as other posts on using the Live CD to do a fresh install. However, the problem I am experiencing is when I bring up the install screen, it says the following: This computer has multiple operating systems on it. What would you like to do. (3 options) Install Ubuntu 12.04 alongside them Replace all with Ubuntu 12.04 (Warning, this will delete files across ALL operating systems) Something else (you can create or resize partitions yourself) This is different from what is in other posts, as mine states that there are "multiple O.Ses" and doesnt individually allow me to replace the Ubuntu 11.10. I don't want to replace ALL O.S.es: I need to preserve Windows 7 and am only trying to replace the old Ubuntu 11.10 partition with the new 12.04 64 bit. I did have Ubuntu installed via Wubi (I believe it was 10.04) prior to putting 11.10 in a separate partition, but I have removed it via Add/Remove programs in Windows. I was wondering how to go about doing this... Should I use the "Something else" option to bring up the partition manager, and just assign my existing 11.10 partition with root mount point + swap space. Will this do the same thing by overwriting with fresh 12.04 install?? I appreciate all your help.

• Launcher sometimes appears while full screen in VM (virtaulbox) - how to stop it?

  - by frumbert

  Launcher is great, and it helps me finds stuff. I have the latest release of 12. But when I'm full screen in VirtualBox running another operating system and I hit some key combination I haven't yet figured out, Laucher suddenly grabs keyboard focus. It might be alt-tab, it might be left-control x. I have physically pulled both the windows key and FN key off my laptop because they get in the way, so it's probably not the windows key. You don't know the focus has been stolen because the full screen app (VirtualBox) is still full screen and launcher is in the background. But you're busy typing into a laucher search box, not your foreground application. This is particularly annoying. In my screenshot (taken from a camera, because the built in screen capture program can't capture a screenshot containing the launcher...) the windows VM is the foreground application, but the launcher has come up and is capturing the keyboard: http://imgur.com/SrMRr I would like a foreground full screen app to stay that way. Is there a way that I can keep the launcher but only have it activate (e.g. pop out with its search box) if I physically click the button, not type some random key combination that foreground applications can get confused about? Otherwise I can do without the launcher, because doing my actual work is more involved than just launching programs.

• Why does my mic boost automatically go to 100 on every boot?

  - by Ben

  When my computer turns on, it automatically sets the "mic boost" sound setting to 100. This causes a loud static sound in my speakers. I can manually go to alsamixer and turn the mic boost down manually, but I would prefer it if I didn't have to do this every time I turn the computer on. I've tried running sudo alsactl store after fixing the settings, and this does save them, but I have to run sudo alsactl restore to restore the settings. This means that I have to manually fix the sound every time I start the computer anyway, so it isn't really a fix. I tried putting sudo alsactl restore in my startup programs, but that didn't seem to fix anything. I'm running Ubuntu 12.04, but I started having this problem before upgrading from 11.10. I'm using a Sony Vaio laptop. I'm not really sure what made it start; it seemed like I just started having the problem randomly one day. Any help would be appreciated! Edit: here is the output from running amixer: http://paste.ubuntu.com/1060080/
