  • Enable permanent vertical and horizontal scroll bars

    - by Rolen Koh
    I am facing a problem and it is in Ubuntu (14.04) permanent scroll bar is not there but it appears when you move the mouse pointer to right most side or bottom most side. But it is very difficult to use and lately it takes too much to appear and sometimes it doesn't appear at all and so i have to close the application and reopen it. So i want to ask how to enable permanent scroll bars on right side and bottom most side. I am sure many people must have faced this problem before me. Thanks. P.S: By permanent i mean scroll bars should be visible all the time.

  • Ubuntu 12.04 wireless does not detect networks

    - by dudeitsdevin90
    I installed Ubuntu on a partition of my MacBook Pro. Wireless connections work fine when I switch to OSX, but the wireless networks are not even detected when I boot Ubuntu. I installed Wicd as a new network manager, but I'm still having the same problem. Ubuntu works on a wired connection though. I have searched the web for a solution... similar questions have been asked but I have not been able to find a way to fix this problem. Any help would be greatly appreciated.

  • How to properly document functionality in an agile project?

    - by RoboShop
    So recently, we've just finished the first phase of our project. We used agile with fortnightly sprints. And whilst the application turned out well, we're now turning our eyes on some of the maintenance tasks. One maintenance task is that all of our documentation appears in the form of specs. These specs describe 1 or more stories and generally are a body of work which a few devs could knock over in a week. For development, that works really well - every two weeks, the devs get handed a spec and it's a nice discrete chunk of work that they can just do. From a documentation point of view, this has become a mess. The problem with writing specs that are focused on delivering just-in-time requirements to developers is we haven't placed much emphasis on the big picture. Specs come from all different angles - it could be describing a standard function, it could describing parts of a workflow, it could be describing a particular screen... And now, we have business rules about our application scattered across 120 documents. Looking for any document for a particular business rule or function in particular is quite hard because you don't know which document has this information, and making a change request is equally hard because once again, we are unsure about which spec to make the change. So we have maybe a couple of weeks of lull before it's back to specing out functionality for the next phase but in this time, I'd like to re-visit our processes. I think the way we have worked so far in terms of delivering fortnightly specs works well. But we also need a way to manage our documentation so that our business rules for a given function / workflow are easy to locate / change. I have two ideas. One is we compile all of our specs into a series of master specs broken by a few broad functional areas. The specs describe the sprint, the master spec describe the system. The only problem I can see is 1) Our existing 120 specs are not all neatly defined into broad functional areas. Some will require breaking up, merging etc. which will take a lot of time. 2) We'll be writing specs and updating master specs in each new sprint. Seems like double the work, and then do the devs look at the spec or the master spec? My other suggestion is to concede that our documentation is too big of a mess, and manage that mess going forward. So we go through each spec, assign like keywords to it, and then when we want to search for a function, we search for that keyword. Problems I can see 1) Still the problem of business rules scattered everywhere, keywords just make it easier to find it. anyway, if anyone has any decent ideas or any experience to share about how best to manage documentation, would really appreciate it.

  • Why does Ubuntu 10.10 show blank screen during startup?

    - by user8372
    When I try to login to Ubuntu 10.10 I get a flickering screen for a second showing - Ubuntu 10.10 ............. and then I get a blank purple coloured screen[Ubuntu's theme colour] which doesn't progress any further Can anybody suggest a remedy to this problem? From whatever questions I searched in various Ubuntu Forums it seems like this problem is likely caused by a missing NVIDIA Display Driver[which is being used in my Sony Vaio Laptop] update in Ubuntu releases If that's the case then how can I update my NVIDIA Display Driver for Ubuntu 10.10 without being able to log into the Ubuntu 10.10?

  • Server 13.10 Install Hangs

    - by noloader
    I'm trying to install Server 13.10 on some old hardware for testing (HP/Compaq dc5850, with Athlon X2 2.3 GHz dual core, 4GB RAM). The third screen is "Select Language" and the machine appears to hang. Ath e selection screen, the keyboard and mouse does not work. I integrity checked the CD and it checked out OK. I also performed a second ISO download and it cross checked with my initial download: $ md5 Desktop/ubuntu-13.10-server-amd64.iso Downloads/ubuntu-13.10-server-amd64.iso MD5 (Desktop/ubuntu-13.10-server-amd64.iso) = 4d1a8b720cdd14b76ed9410c63a00d0e MD5 (Downloads/ubuntu-13.10-server-amd64.iso) = 4d1a8b720cdd14b76ed9410c63a00d0e I was able to install Server 12.04 on the same machine. The problem with 12.04 is the OpenStack packages are too old, and I wanted to try something with fresher packages. My problem appears similar to I cannot install Ubuntu Server 12.10. The Installer hangs at the language selection, but my ISOs appear to be good and the disc appears to be good. Any ideas?

  • Applying the Knuth-Plass algorithm (or something better?) to read two books with different length and amount of chapters in parallel

    - by user147133
    I have a Bible reading plan that covers the whole Bible in 180 days. For the most of the time, I read 5 chapters in the Old Testament and 1 or 2 (1.5) chapters in the New Testament each day. The problem is that some chapters are longer than others (for example Psalm 119 which is 7 times longer than a average chapter in the Bible), and the plan I'm following doesn't take that in count. I end up with some days having a lot more to read than others. I thought I could use programming to make myself a better plan. I have a datastructure with a list of all chapters in the bible and their length in number of lines. (I found that the number of lines is the best criteria, but it could have been number of verses or number of words as well) I then started to think about this problem as a line wrap problem. Think of a chapter like a word, a day like a line and the whole plan as a paragraph. The "length" of a word (a chapter) is the number of lines in that chapter. I could then generate the best possible reading plan by applying a simplified Knuth-Plass algorithm to find the best breakpoints. This works well if I want to read the Bible from beginning to end. But I want to read a little from the new testament each day in parallel with the old testament. Of course I can run the Knuth-Plass algorithm on the Old Testament first, then on the New Testament and get two separate plans. But those plans merged is not a optimal plan. Worst-case days (days with extra much reading) in the New Testament plan will randomly occur on the same days as the worst-case days in the Old Testament. Since the New Testament have about 180*1.5 chapters, the plan is generally to read one chapter the first day, two the second, one the third etc... And I would like the plan for the Old Testament to compensate for this alternating length. So I will need a new and better algorithm, or I will have to use the Knuth-Plass algorithm in a way that I've not figured out. I think this could be a interesting and challenging nut for people interested in algorithms, so therefore I wanted to see if any of you have a good solution in mind.

  • Is using build-in sorting considered cheating in practice tests?

    - by user10326
    I am using one of the practice online judges where a practice problem is asked and one submits the answer and gets back if it is accepted or not based on test inputs. My question is the following: In one of the practice tests, I needed to sort an array as part of the solution algorithm. If it matters the problem was: find 2 numbers in an array that add up to a specific target. As part of my algorithm I sorted the array, but to do that I used Java's quicksort and not implement sorting as part of the same method. To do that I had to do: java.util.Arrays.sort(array); Since I had to use the fully qualified name I am wondering if this is a kind of "cheating". (I mean perhaps an online judge does not expect this) Is it? In a formal interview (since these tests are practice for interview as I understand) would this be acceptable?

  • CS4326/7 sound chipset on Thinkpad 600E

    - by user7120
    OK, I know this has been a problem for a while, and I know by now this really old Pentium II laptop is really really really obsolete. However, I have installed Lubuntu 10.10 on this laptop and things seem to work fine except the sound. Now I've read and gone through a bunch of tutorials and guides to working around this, none of which have worked. I have gone through this Ubuntu bug report and that doesn't work either. The problem I think is that the latest workaround is (understandably) about two Ubuntu versions behind. Now I'm not sure what has changed since then to make that workaround not work, but I would appreciate any help. Thanks

  • How to limit concurrent file access on a Samba share?

    - by JPbuntu
    I have a Ubuntu 12.04 file server running Samba. There are 6 windows machines that access the server, as well as two people that will occasionally access files remotely. The problem that I am having is that the CAD/CAM software we are using doesn't seem to request file locks, meaning if two people open a file at the same time, the first person to close the file will get their changes overwritten if the second person saves the file. I tried changing the smb.conf to strict locking = yes but this doesn't seem to have any effect. File locking with excel seems to work fine, so I know that Samba is using the file locks...if they were put on the file in the first place. Is there a way (either in Samba or Ubuntu) to only allow one user to have a file open at a time? If not does anyone have any suggestions for managing a problem like this?

The game will be a platformer which will use tile maps, so to start i will create a mask matrix indicating the tiles to be loaded, and etc..., so my problem is, how to handle the scrolling? should i create a giant mask matrix indicating in each position of the whole level what is supposed to be loaded, and according to the position of the player, change the section to be drawed?? Is this a correct approach to this situation??

  • UI font has rendering glitches in GNOME Shell

    - by user353889
    I don't really know how to describe this problem in English. A picture can say more words - look at the tabs at the top of the linked image. The current font settings are shown as well. I don't know what basic info I should provide so if something missing, please tell me. Ubuntu 12.04 GNOME Shell 3.4.1 I know, a reboot can make everything normal but I'm looking for a more permanent solution that can fix this problem (or bug). Update Thanks for Fitoschido, I finally know what keyword I could use for googling. I think it's a bug of gnome shell. https://bugs.archlinux.org/task/34847

  • Drivers are not detecting on my Dell inspiron 5420 (14R 3rd generation)

I'm a new user of ubuntu, and willing to use it permanently. In this condition I tried some solutions from the web but didn't get out from this problem. For this I'm knocking to you, If you give me the proper solution for getting out of this problem, I'll be very helpful to you all. Thanks

  • 12.04 - sound is laggy when running games through Wine

    - by orzechowskid
    Lenovo U400 Wine 1.5.5 Ubuntu 12.04 with all updates applied I'm experiencing severe (~500ms) audio lag in all games run in Wine. Portal 2, Half-Life, World of Goo, and Fallout are all exhibiting this problem. When I run winecfg though and click the "Test Sound" button at the bottom of the Audio tab, the sound effect appears to play immediately. So I'm not sure what's going on. I don't think it's a problem with PulseAudio by itself since totem videos and Youtube clips both play in perfect sync. Anyone have any ideas on where to start fixing this? thanks! (edit: I thought this was limited to Steam games but I installed a non-Steam game and I now see that's not the case. I get audio lag in other apps too.)

  • How to install Ubuntu using a USB stick?

    - by J. N.
    I cannot install Ubuntu 11.10 from a USB stick. It doesn't boot to Ubuntu page for installation but remains on Windows 7. I've downloaded the 11.10 version iso file and burnt it to a USB stick. After I inserted it, the USB stick is a symbol of Ubuntu installation and I clicked wubi to try to install it. But it didn't boot to Ubuntu but stayed on Win 7 after restart. It occurred error and said "windowsBackend" object has no attribut "cd_path" when I chose "Help me to boot from CD". I thought it's the problem of my computer model (acer travelmate 8481), but it can't boot on an old computer using XP as well. How can I solve this problem and install Ubuntu to replace Windows?

  • Is there an opposite for the term "Backporting"?

    - by Avian00
    As I understand, the term "Backporting" is used to describe a fix which is applied in a future version which is also ported to a previous version. Wikipedia definition is as follows: Backporting is the action of taking a certain software modification (patch) and applying it to an older version of the software than it was initially created for. It forms part of the maintenance step in a software development process... For example: A problem is discovered and fixed in V2.0. The same fix is ported and applied to V1.5. What is the term when this is done in the opposite direction? The problem is discovered and fixed in V1.5. The same fix is ported and applied to V2.0. Would the term "Backporting" still apply? Or is there a term such as "Forwardporting" (which amusingly sounds a lot like "Port Forwarding")?

  • How to learn to translate real world problems to code?

    - by StudioWorks
    I'm kind of a beginner to Java and OOP and I didn't quite get the whole concept of seeing a real world problem and translating it to classes and code. For example, I was reading a book on UML and at the beginning the author takes the example of a tic tac toe game and says: "In this example, it's natural to see three classes: Board, Player and Position." Then, he creates the methods in each class and explains how they relate. What I can't understand is how he thought all this. So, where should I start to learn how to see a real world problem and then "translate" it into code?

  • How do you ensure consistent experience across multiple graphics cards (or even driver versions)?

    - by Grigory Javadyan
    So I was writing a simple 2D game with OpenGL and SDL and had this problem when there was awful tearing when running in windowed mode (even though I explicitly asked SDL_SetVideoMode to use double buffering). Didn't worry about it all too much because most of the time the game grabs the entire screen, windowed mode is just for debugging. Anyway, yesterday I updated my nVidia drivers and tearing disappeared, the game runs smooth and looks nice in windowed mode too. I can see how the problem may be in the graphics driver, but this leads to a question. Obviously, professional game developers have to deal with a lot of different hardware/software configurations. What are the techniques they use to make sure the game looks the roughly the same on different graphics cards or even the same model of graphics card, but with different driver versions?

  • Mic not working when vga connector removed

    - by yygyt
    I have a computer that should run continuously without any connection to a monitor. For developmental purposes I have been keeping the vga connection with the monitor and experienced no problem until now. When I start the machine removing the vga connection beforehand, external microphone does not work. At first I didn't know anywhere to look and see the problem, but after a google search I saw that there is a command as alsamixer I ssh the machine end type alsamixer when it is connected to the monitor, here is the result If I remove monitor connection and reboot again, and then type alsamixer, I see the error, $ alsamixer cannot open mixer: No such file or directory I suspect that this error is related to X somehow. I really don't know anything about what goes beyond. This machine needs to work without any connection to a monitor. I would deeply appreciate any suggestions.

  • Compiz using 40% CPU on Ubuntu 13.10

    - by Olli
    After upgrading to 13.10, compiz process has started taking up to 40% of CPU resources. In addition, Unity is sluggish just like in this recent question Compiz at 30% of CPU on Thinkpad T420. My PC is HP Compaq NX6310 and Compiz version is 0.9.10.2. First I had error message during boot, but did find solution for that (Bug #1014289) by updating the kernel to newer 3.11.4, it did not change the CPU usage. For the CPU problem I tried solution for Bug #1221837 by adding the line MESA_GL_VERSION_OVERRIDE=1.4 in the file /etc/environment - that did not help me, so my problem seems not to be the same bug. Any suggestions on how to resolve this issue?

  • Network connection on an Acer Aspire 5253?

    - by fuquam
    Brand new to Ubuntu and PCs for that matter. I've been a Mac user all my life but wanted to try Ubuntu on the cheap, so I bought an Acer Laptop 5253-BZ893 and i got Ubuntu 10.10 installed with no problem. The only problem i have is, that i get no network connection options, wired or wireless. I just get No Network Devices Available. The computer came with Windows 7 installed and i am able to connect to my wireless network fine using Windows, so i know the computer works. Also i've been searching forums and google for hours trying to figure out why I can't get a network connection in Ubuntu but so far no luck. Any suggestions? Thanks in advance.

  • EF Doesn't Like Same Named Tables

    - by Anthony Trudeau
    Originally posted on: http://geekswithblogs.net/tonyt/archive/2013/07/02/153327.aspxIt's another week and another restriction imposed by the Entity Framework (EF). Don't get me wrong. I like EF, but I don't like how it restricts you in different ways. At this point you may be asking yourself the question: how can you have more than one table with the same name?The answer is to have tables in different schemas. I do this to partition the data based on the area of concern. It allows security to be assigned conveniently. A lot of people don't use schemas. I love them. But this article isn't about schemas.In the situation I have two tables:Contact.PersonEmployee.PersonThe first contains the basic, more public information such as the name. The second contains mostly HR specific information. I then mapped these tables to two classes. I stuck to a Table per Class (TPC) mapping, because of problems I've had in the past implementing inheritance with EF. The following code gives you the basic contents of the classes.[Table("Person", Schema = "Employee")]public class Employee {   ...   public int PersonId { get; set; }   [ForeignKey("PersonId")]   public virtual Person Person { get; set; }}[Table("Person", Schema = "Contact")]public class Person {   [Key]   public int Id { get; set; }   ...}This seemingly simple scenario just doesn't work. The problem occurs when you try to add a Person to the DbContext. You get an InvalidOperationException with the following text:The entity types 'Employee' and 'Person' cannot share table 'People' because they are not in the same type hierarchy or do not have a valid one to one foreign key relationship with matching primary keys between them..This is interesting for a couple of reasons. First, there is no People table in my database. Second, I have used the SetInitializer method to stop a database from being created, so it shouldn't be thinking about new tables.The solution to my problem was to change the name of my Employee.Person table. I decided to name it Employee.Employee. It's not ideal, but it gets me past the EF limitation. I hope that this article will help someone else that has the same problem.

  • Ubuntu One doesn't show captcha in windows 7

    - by Fredrik Hansson
    I try to set up a new U1 account in W7. However, the sign on screen reports "There was a problem getting the captcha, reloading" - but nothing seems to happen. I tried it on two different computers (in the same home network). Same result. Anything to do or is U1 for W7 corrupt? Also experiencing this problem. Trying to install latest U1 on brand new Toshiba Win7 laptops at work and the captcha field is simply blank, there is nothing to copy. Tried refresh, restart, reload and different browsers (Firefox 13, IE9) and nothing improved the situtation. Without being able to see the captcha I cannot do anything at all and will have to use silverlight if I can't overcome this.
