  • Why am I missing the Ubuntu icon on the log-in screen?

    - by dtdlurch
    I am running Ubuntu 12.10. On the log-in screen, there is no Ubuntu icon for me to click on to change desktop environments. I know where it should be, but it is simply not there. Why is this? And how can I get it back??? I just installed Cinnamon and I would very much like to switch to this environment. I apologize if this is has been addressed elsewhere, but I honestly did try to research before asking. I found several similar questions, but nothing that has answers that helped my situation. And an hour of Googling did not produce anything helpful at all. Thank you for your help.

  • Looking for open-source solutions for a knowledge sharing website

    - by Bundarr
    There is a need in my workplace to setup a knowledge sharing site, a place where users can discuss projects they are working share documentation ask questions I am looking for a open-source system that answers these needs, and that can be setup in a week, and requires only PHP and MySQL. I am a Wordpress fan and developer and could easily implement such a system in Wordpress, however this system needs to be very simple to use for the technically challenged. Without customization, Wordpress users would still need to login to the "back-end" to post. I like the Stackexchange (OSQA) format, but these do not allow for file uploading out of the box. I do not have experience with Buddy Press, would this be an alternative?

  • What should be learned for someone starting in Android Games?

    - by user14544
    I know this might be a little subjective. But I've read the other questions. A lot of answers kept on popping up like to use box2d, libgdx, andEngine, etc. So the real question is, what would be the best to start off with as a beginner. I have some experience with java code, just by reading about in the Oracle Docs. I've gone through Flash and Eclipse. When i mean gone through, i don't mean i have actually created my own game from Flash or Eclipse, but i just learn things here and there. Currently I'm reading Beginning Android for Beginners but I don't have the knowledge to implement my own Ideas into the game tutorials because of lack of experience. I'm looking for a way to learn how to program to create games for Android. While at the same time get experience from programming. I do not want to learn those drag and drop game making applications such as GameMaker.

  • Ubuntu 14.04 not booting before Windows 8.1

    - by user280244
    I try too boot my computer into Ubuntu, but I end up having to manually select Ubuntu from the devices menu, even though it was supposed to boot first. Instead Windows 8 boots up like Ubuntu isn't even there! And GRUB works just fine when Ubuntu is selected in the boot device menu. (How else am I on?) I tried using EasyBCD but kept getting errors from the windows boot manager. And just in case it helps, during installation of Ubuntu it didn't recognize windows 8, and I had to resize and install manually. Anything I can do? Notes: EVERYONE!!! GRUB WORKS PERFECTLY!!! IT IS AN ERROR IN THE HP BOOT MENU AS I HAVE PREVIOUSLY SAID!!! PLEASE DO NOT GIVE ME ANSWERS FOR GRUB EDITS IN THE FUTURE!!! Here are my specs: PC type: HP 2000-2d49WM Notebook PC RAM: 4GB Swap: 2GB Processor: AMD E-300 Vision 1.3 GHz x2 BIOS Edition: N\A Until further notice

  • Data structure for file search

    - by poly
    I've asked this question before and I got a few answers/idea, but I'm not sure how to implement them. I'm building a telecom messaging solution. Currently, I'm using a database to save my transaction/messages for the network stack I've built, and as you know it's slower than using a data structure (hash, linkedlist, etc...). My problem is that the data can be really huge, and it won't fit in the memory. I was thinking of saving the records in a file and the a key and line number in a hash, then if I want to access some record then I can get the line number from the hash, and get it from the file. I don't know how efficient is this; I think the database is doing a way better job than this on my behalf. Please share whatever you have in mind.

    - by user206996
    I want to permanently mount a few Windows shared folders. I googled that topic and found a lot of good answers, but with all the solutions I have a little problem: I believe I can't properly give an address of shared folder. I can find it following way: "Network" - "Windows Network" - "WORKGROUP_name" - "Computer_name" - and there is some folder i would like to mount. How can I write the path to the folders in terminal? UPD i can access needed folder throw address in location bar smb://server/ro/, but i try mount it by editing /etc/fstab file (using guide https://wiki.ubuntu.com/MountWindowsSharesPermanently) i get error mount error: could not resolve address for server: Unknown error PS in /etc/fstab : //SERVER/RO /media/server cifs username=user,password=pwd, uid=1000,iocharset=utf8 0 0

  • What would be a good way to request comments?

    - by WarpEnterprises
    In the project/team I'm working the frequency of comments is a little low. One reason might be that it is not clear to the long-time devs what lines in the code really needs a comment (each part of the project has quite fixed devs). To increase this we plan to let team members review the code and check in "requests for comments", which the main dev of that part should replace with useful comments. Do you think this could work? If "yes": what tags should we use to mark? (e.g. //TODO please comment) Can you think of alternatives for this process? Edit: I appreciate your answers about best practice in commenting and writing code, and I completey agree. But my question targets the cases where refactoring is not an option (not wanting to change working code, not wanting to "accuse" main dev of producing code that needs refactoring,...) - so only more or better comments are an option (at least for this question).

  • Inversion of control in Unity?

    - by user3206275
    I am semi-experienced .NET developer who has just began working with Unity. I am trying to decide on how to make IoC work in Unity 4.X ( I have not yet tested anything), and I wonder what are the good ways of achieving it. This post and its answers states that Ninject won't work with Unity, however it is old. Is it still true? If yes, what are other means of achieving IoC in Unity ? Edit 1 : I am targeting mainly Windows platform. So I don't need platform interoperability, I just need it to work.

  • How can I redirect the contents of a file to the pastebinit command? [duplicate]

    - by Tim
    This question already has an answer here: How to submit a file to paste.ubuntu.com without graphical interface? 2 answers Whenever I was to store something to show someone here, I run command-with-output | pastebinit. That returns the link to the paste online. For example: echo timtjtim | pastebinit gave me the link paste.ubuntu.com/8010000 Which I can share. How can I do this with a file - for example a log file. Surely I don't have to open - > copy all - > open paste.ubuntu.com -> paste it?

  • How to create a map-like (clouds) texture [duplicate]

    - by user16547
    This question already has an answer here: How do you generate tileable Perlin noise? 9 answers If you place a map of the world on a sphere, it will look like the image is continuous. Basically the left end of the image is sort of a continuation of the right end. You won't be able to see any cuts. I'm trying to create a clouds texture to add to my planet such that it will seem it has clouds. I managed to create the clouds in GIMP, however, I can't figure out how to make sure the left end of my image is a smooth continuation of the right end. For example if you were to map the below image to your sphere (I removed transparency to make it clearer), there would be a very obvious transition from the right end of the image back to the left end on your sphere. How would I create a texture such that I get rid of that? Sorry for my lack of terminology.

  • What makes a language (or feature) "hackerish"?

    - by iCanLearn
    I was reading the comments and answers to this question, and among them I found this: "And Java never was cool, simply because it threw the hacking part out of programming" and this: "And javascript is very hackerish language so after developing your frontend you feel very constraint when you return to java." What's the "hacking part" in programming, and what makes a language "hackerish"? What are some good examples of languages and features in languages that you would call "hackerish"? (Someone might say that I shouldn't be confused by the word "hackerish", that's it's not really a "proper" English word or something like that, but that's besides the point)

  • "Mega Menus" for SEO [duplicate]

    - by Thought Space Designs
    This question already has an answer here: How do I handle having to many links on a webpage because of my menu 4 answers I'm using the term "Mega Menus" loosely here. I'm redesigning my WordPress site (it's going to be responsive), and as part of the redesign, I was debating incorporating some sort of descriptive menu setup. For example, normal navigation drop down menus come in the form of unordered lists of links like so: <nav> <ul> <li> <a href="#">Link1</a> </li> <li> <a href="#">Link2</a> </li> <li> <a href="#">Link3</a> <ul> <li> <a href="#">Sub Link1</a> </li> <li> <a href="#">Sub Link2</a> </li> <li> <a href="#">Sub Link3</a> </li> </ul> </li> <li> <a href="#">Link4</a> </li> </ul> </nav> What I'm looking to do is build my drop down menus with more information than your standard menu. For example, I have a top level link named "Team", and under that link, I want to make a large drop down that contains head shots, headers (in the form of styled p tags) and brief (<100 words) descriptions of each team member (only 2 currently). I want to accompany this with a "Read More" link that takes you to their actual team page. This is just one example, of course, and the other top level links would also have descriptive drop downs in the same fashion. On mobile, I was planning on hiding the "mega menu", and delivering a standard unordered list of links. Here's what I was thinking for overall structure and syntax: <nav> <ul> <li> <a href="#">Home</a> </li> <li> <a href="#">About</a> </li> <li> <a href="#">Team</a> <ul> <!-- DESKTOP --> <li class="mega-menu row"> <a class="col-sm-6" href="#"> <div class="row"> <div class="col-sm-4"> <img src="#" alt="Team Member 1" /> </div> <div class="col-sm-8"> <p class="header">Team Member 1</p> <p>Short description goes here.</p> </div> </div> </a> <a class="col-sm-6" href="#"> <!-- OTHER TEAM MEMBER INFO --> </a> </li> <!-- END DESKTOP --> <!-- MOBILE --> <li> <a href="#">Team Member 1</a> </li> <li> <a href="#">Team Member 2</a> </li> <!-- END MOBILE --> </ul> </li> <li> <a href="#">Contact</a> </li> </ul> </nav> Can anybody think of any potential SEO ramifications of doing this? I'm not going to be loading these menus full of links, so it shouldn't hurt page rank, but what are the effects of having a good bit of text and maybe even forms within nav elements? Is there such a thing as overloading nav with HTML? EDIT: Here's an example of what the menu would look like rendered on desktop. I'm currently hovering the "Team" menu, but you can't see because my mouse went away when I took the screenshot. EDIT 2: This question is not a duplicate. I'm not going to have "too many" links in my menus. I'm wondering how having images and text inside of header navigation will affect my menus. Also, I don't just want "yes, this is bad" answers. Please cite your sources and be specific with reasoning.

  • Good source for interview-style coding problems for entry/intermediate developers?

    - by soster
    I have taught myself to code over the past few years and do not have a computer science degree. As a result, I lack experience from many things, such as the basic homework/test questions many CS graduates take for granted. I recently had a tech screen interview where I fumbled and struggled to finish a (relatively) common question, I believe due to this inexperience. My question to all of you is this: do you know a good source for a bunch of these problems that includes answers, for an entry/intermediate developer who is trying to gain coding problem solving experience? The ones I've been able to find on the internet are for coding teams, so they're a bit too complicated for me. Thanks so much in advance.

  • Is testable code actually more stable? [closed]

    - by Xodarap
    A google scholar search turns up numerous papers on testability, including models for computing testability, recommendations for how ones code can be more testable, etc. They all come with the assertion that more testable code is more stable, however I can't find any studies which actually demonstrate this. I tried looking for studies evaluating the effect of testable code vs. quality, however the closest I can find is Improving the Testability of Object Oriented Systems, which discusses the relationship between design flaws and testability. Is testable code is actually more stable? And why, or why not? Please back up your answers with references or evidence to back up your claim.

  • Webcam Q&A page with guest "speakers" ideas?

    - by myladeybugg
    I want to host one way webcam Q&A's/AMA's and embed it on my sites webpage. I must be able to have specified hosts for these Q&A's connect quickly and easily to the webpage, and read user posted messages (questions) for interaction. I know there are some systems out there, like tinychat, but I'm unaware if there is anything exactly used for what I am looking for. Perhaps requiring a specific account/password before allowing streaming on the page, where I can email the host a password or directions to create an account to begin live streaming. Most of these people doing the question and answers on webcam will have little technical knowledge, so extra cookie points goes to ease of use! Thanks for ideas in advance! PS: I apologize if this is the incorrect section for posting this question, this is my first.

  • Software Design and documentation – what do people use that has proved valuable?

    - by eddyparkinson
    When creating software, what do you use to design, document and visualize. Looking for evidence/examples. e.g. Use cases, Pseudo code, Gantt chats, PERT charts, DFD, decision trees, decision tables (Answers maybe used to help teach students) What do you use to help with creating software. Also why; when has it proved valuable? --- Edit -- Proved valuable: The pattern so far suggests that the style of UML tool used is linked to an objective. e.g. "get it straight in MY head", explain to business mangers, quality control.

  • Found a better solution to a problem at work - should I deter from posting the code snippet online?

    - by Calmarius
    I think most of us, programmers, used Stack Overflow to solve every day problems: looked for an efficient algorithm to do something. Now imagine a situation: you have a problem to solve. Googled a bit, found a StackOverflow question but you are not really satisfied with the answers so far. So you have to do your own research: you need to do it because you want it in the company's app. Eventually after some hours you have found the better solution. You're happy, you added it to the company's code base, then you want to submit your answer with a code snippet (just several lines) to the question you've found before to help others too. But wait: the company's software is closed source, and you worked on it on the clock. So does this mean I shouldn't post the answer neither at work nor at home to that question in the rest of my life, because I solved it at work, and the company owns that piece of code?

  • Should I be worrying about limiting the number of textures in my game?

    - by Donutz
    I am working on a GUI in XNA 4.0 at the moment. (Before you point out that there are many GUIs already in existance, this is as much a learning exercise as a practical project). As you may know, controls and dialogs in Windows actually consist of a number of system-level windows. For instance, a dialog box may consist of a window for the whole dialog, a child window for the client area, another window (barely showing) for the frame, and so on. This makes detecting mouse hits and doing clipping relatively easy. I'd like to design my XNA GUI along the same lines, but using overlapping Textures instead of windows obviously. My question (yes, there's actually a question in this drivel) is: am I at risk of adversely affecting game performance and/or running low in resources if I get too nuts with the creating of many small textures? I haven't been able to find much information on how resource-tight the XNA environment actually is. I grew up in the days of 64K ram so I'm used to obsessing about resources and optimization. Anyway, any feedback appreciated.
