• Can't Boot Ubuntu, video drivers or x-server problem?

  - by ZacharyH

  I was uninstalling some programs that I installed to try and get my iPod touch working with Ubuntu (I gave up on that) when ubuntu just crashed. Now after I choose ubuntu in GRUB, it gives me a screen that says "Ubuntu is running in low-graphics mode: your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself" It was working just fine before I started to uninstall those programs. I think that I might have uninstalled something necessary to the system. If I click OK on the screen, it gives me options to reconfigure, troubleshoot, exit to console, or restart X. But no matter what I choose I still can't boot into ubuntu - I get stuck looking at the splash screen which stalls forever. I was receiving support from one of my mate's and he was doing something with the LiveCD, and now the message doesn't pop up any more, I just get stuck at a never ending splash screen. Any help would be appreciated, thanks!

• PCI hotplug doesn't seem to work

  - by user245454

  In virsh I detach a PCI bus from host and attach it to a VM. I don't see any errors in these steps. But I don't see the PCI device listed in the VM. virsh # nodedev-dettach pci_0000_01_00_0 Device pci_0000_01_00_0 dettached virsh # attach-device VM1 pci_add.xml Device attached successfully $ cat pci_add.xml <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x000' bus='0x01' slot='0x00' function='0x0'/> </source> </hostdev> Is PCI hot plug not supported? I am using Ubuntu 12.04.3(kernel 3.8.0-34). I can add the same PCI device through virsh edit VM1 and start the VM1. This way I am able to see the device.

• Need to run `nvidia-xconfig` before booting

  - by RobinJ

  I formatted my whole hard drive, and installed Elementary OS (Ubuntu 10.10) on it in an attempt to get rid of all the problems. It failed. Every since I installed the nvidia-current drivers I first need to boot into recovery mode, and run sudo nvidia-xconfig before booting the system in the normal way. If I don't do this, it will just stop at a black screen after the boot screen, responding to nothing but CTRL+ALT+DELETE and the power button. When I boot the system after running the nvidia-xconfig command I can just start working as usual. Update I suspect it's got something to do with Plymouth. I shall have to try it again before I can confirm it, but removing the quiet and splash parameters from the kernel line in /boot/grub/grub.cfg seems to help. But still, I like my Plymouth screen. A black screen with text rolling over it (or without the text) doesn't attract me much.

• How to start to gain experience of managing a project

  - by Tim

  There are some job requirements of project management experience for a programmer, such as: the candidate has to have some experience managing a project, not necessarily with subordinates, but rather having worked on a project all the way from design down to test. I was wondering what "subordinates" mean here? if there are some books, webpages or elsewhere with both general guideline and simple practical sample projects to help one get some basics about the whole process of a project. I am particularly interested in projects for both Linux and Windows, in C, C++, Python, Java. I am considering to start by playing on my own, not eager to find a company yet. My major was not CS, so I might lack the basics.

• How do I create a WiFi hotspot sharing wireless internet connection (single adapter)?

  - by Ruppesh Nalwaya

  I know how to create a hotspot when connected to a wired network, but when I am using internet from a WiFi connection, this disconnects the wireless connection the moment I activate the hotspot. In Windows I can use Connectify Hotspot, which enables me to share the internet connection from the same wireless adapter as I am creating an access point on. As you can read on the technology overview page: Access Point mode allows you to create a hotspot using the same Wi-Fi card that you are using to access the Internet. How do I do this on Ubuntu?

• Stairway to T-SQL DML Level 4: The Mathematics of SQL: Part 1

  A relational database contains tables that relate to each other by key values. When querying data from these related tables you may choose to select data from a single table or many tables. If you select data from many tables, you normally join those tables together using specified join criteria. The concepts of selecting data from tables and joining tables together is all about managing and manipulating sets of data. In Level 4 of this Stairway we will explore the concepts of set theory and mathematical operators to join, merge, and return data from multiple SQL Server tables.

• Slow writing HDD speed, Ubuntu 12.04 64-bit, Thinkpad T520i

  - by pyc

  It seems that (but I'm not completely sure), that when I'm copying files from gigabit network to HDD, I can't use full potential of the network which in my case is about 60 MB/s, because HDD writing is so slow like lower than 10 MB/s, and also it's slowing down the whole system which becomes pretty much unresponsive, almost impossible to work with. Copying files to samba share residing at Ubuntu machine, connected to share from Windows 7, I'm completely sure my network equipment is OK, and there's no CPU intensive process on Ubuntu except smbd getting about 10-20% from time to time which I think is OK. Something here is burried deep I think, maybe even in kernel. Already tried to switch from AHCI to compatibility mode, and turning acpi on and off - nothing helped. So it's like HDD buffer is full and emptying slowly while machine is sluggish, load is about 3 to 4. Somebody experienced the similar problems? Some help on troubleshooting process and identifying the cause would be helpful too :) Thanks!

• What do you do when the code isn't complicated enough?

  - by Chris

  After six months of development on a project, our stakeholders have had a "gut check" and have decided that the path that we've been walking (a custom designed application framework and data access layer) is holding us (the developers) back from quickly developing the features they would like to see. After several days of debate management and the development team have decided to scrap the current incarnation and start over using ASP.net MVC, with Entity Framework as the bases of the a 'quick and dirty', lets just get it done project. In days following, our senior developer who has never worked with MVC or Entity Framework has finally gotten into a sample project and done some work. His take on ASP.net MVC, "this is not software engineering". So my question is this; what do you do, when one doesn't think the code is complicated enough?

• Dropbox install stuck at 99%, how do I fix it? (and any dpkg errors)

  - by John

  I tried to install Dropbox using How to install Dropbox?, or with apt-get install nautilus-dropbox. Dropbox loads until 99% and then hangs, causing the system to go to 100% cpu usage. If I reboot or close the terminal, I sometimes get dpkg errors which prevent me from using apt-get or Software Center to perform any package management functions. I would like to resolve all these and just get Dropbox working. How do I do that? Note: This question is possibly answered in two parts: The accepted answer tells you how to install Dropbox. But if you have dpkg errors, see this answer before you use answer 1 to install Dropbox.

  - by daker

  I have dual boot config with kubuntu 12.04 and Windows7. My problem started this morning when I tried to boot kubuntu. Everything worked fine a couple of days ago and I have not done any mayor system configurations since then. Choosing kubuntu options from grub gives me this screen A couple of minutes later this screen is shown And then it gets stuck. Have been waiting for ~5mins without anything happening. I have tried running fsck from recovery menu without any errors. I have also tried booting in failsafex mode which gives me "Fatal server error: no screens found". apt-get update gives me "Duplicate sources.list entry". I have also tried fixing broken packages from recovery menu. What should I do next?

• Where can I find statistics / figures on how long testing should / could take?

  - by NoCarrier

  I'm trying to convince management that testing/QA takes considerably longer than non-developers think. Some smaller shops don't have budgets for testers and phbs automatically assume the developer will spend a few minutes after every build "testing" and deliver a perfectly functional system. Can someone point me to some numbers? e.g. Testing should be XX% of your total man hour count , etc etc? Or perhaps some real world experience? My goal is to have some numbers that are grounded in real life so I can make time/effort allocation justifications for "proper" testing when preparing estimates and timelines for applications. Maybe not full blown 100% TDD, but pragmatically close to it. I apologize if I seem vague.

• AWS CloudFormations, Oracle Assembly Builder, Chef and Puppet

  - by llaszews

  I blogged about the difference and similarities between AWS CloudFormations and Oracle Assembler builder to package your software stack for deployment/provisioning to the cloud. However, these tools do not deal with software stack versioning and configuration management. This is where tools like Chef and Puppet come into play. Puppet and Chef points of interest: 1. Can be used in any cloud environment (rackspace, private cloud etc). 2. There is a debate between which is better. I am not going to get into this debate other then to say Puppet is more mature. 3. AWS CloudFormations can integration with both Chef and Puppet. A good blog on AWS CloudFormations and the need for something more: AWS CloudFormation

• Storing E-mail addresses more efficiently in SQL Server

  A lot of people are storing large quantities of e-mail addresses in their systems. Since a large percentage of any system's user base is going to be supplying e-mail addresses from a few of the vastly popular providers (such as GMail and Hotmail), we are storing the "@gmail.com" and "@hotmail.com" parts of those addresses on disk over and over and over again.

• Script to calculate the Median value for SQL Server data

  The standard SQL language has a number of aggregate functions like: SUM, MIN, MAX, AVG, but a common statistics function that SQL Server does not have is a built-in aggregate function for median. The median is the value that falls in the middle of a sorted resultset with equal parts that are smaller and equal parts that are greater. Since there is no built-in implementation for the median, the following is a simple solution I put together to find the median.

• Is it possible to make the desktop background transparent or otherwise hidden?

  - by EndangeredMassa

  I'm running Ubuntu in a virtual machine via VirtualBox. I have the seamless mode turned on, which is pretty cool. However, if I move an Ubuntu window around quickly, I can see the redraw of the ubuntu background quickly before it's hidden by VirtualBox again. This isn't a huge deal, but I'd like to fix it, if possible. I see two possible options that don't involve changing VirtualBox code: 1. Make the Ubuntu desktop transparent 2. Make the Ubuntu desktop hidden entirely Is it possible to do either? I know that Compiz Fusion has/had a feature to do this for their cube effects, but I don't think that I can run this on the VM. And, even if I could, I don't want to run those services for this one small feature.

• Can't install ATI proprietary drivers in 12.10

  - by EApubs

  I have a laptop with ATI Radeon 6770M HD Hybrid graphics card. In Ubuntu 12.04, I installed the fglrx driver through "additional drivers" and it worked. (I can even switch GPUs). But in the new Ubuntu 12.10, after installing, Unity won't load. Only the mouse and the wallpaper. If I initialize the settings sudo aticonfig --initial then after rebooting it gives a warning saying I'm in low graphics mode! How to fix this? PS : Earlier i used software source to install the drivers. But when using the terminal, I got this warning : update-alternatives: warning: forcing reinstallation of alternative /usr/lib/fglrx/ld.so.conf because link group x86_64-linux-gnu_gl_conf is broken Update : Filed a bug report in launchpad : https://bugs.launchpad.net/fglrx/+bug/1068661
