• Installation taking a very long time

  - by user290522

  I am installing Ubuntu 14.04(32-bit) on my laptop (Compaq Presario V2000), and after about 7 hours, it is still in Congiguring bcmwl-kernel-source (i386) mode. The messages I read are as follows: ubuntu kernel: [22814.858163] ACPI: \_SB_.PCI0.LPC0.LPC0.ACAD: ACPI_NOTIFY_BUS_CHECK event: unsupported with the numbers in the square brackets increasing. I have had Windows XP professional on this laptop, and I am erasing it. I am not sure if I should turn off the laptop, and start all over again. About 4 years ago I installed Ubuntu on this laptop, and that was very fast. The only problem I encountered was my wireless, and could not make it to work, and switched back to Windows. I appreciate any comments regarding this installation taking such a long time.

  - by Steen Schmidt

  The other day I was talking to a customer about how you can do a P2V in OVM.

• On my way home ...

  - by Mike Dietrich

  Modern technology is nice - sitting in the speed train from Holyhead to London Euston - working a bit. This means: I'm heading home. Still 16 hours to go - but up to now everything seems to work fine. Irish Ferries did a great job. Even though they might never have seen some many passengers entering the Ulysses (what a good name for a ship to start the journey with) everybody was so friendly and helpful. The night at Holyhead station ... ahm ... But the train left right in time. German airspace is still closed until at least 8pm tonight. And Irish airspace seems to be closed as well today. So it might be the best decision to take the longer journey. At least now I have the chance to see some countryside (a bit flat out there - but very green) ;-)

• Live CD doesn't boot, drops to Busy Box shell

  - by D3c3nt Boy

  I am a Windows user and I'm keen to shift to Linux, so I made live CD of Ubuntu 10.10 (Maverick). This is my very first time to use Ubuntu. I put CD in the drive and set the BIOS to boot it, and the Ubuntu CD worked and logo of Ubuntu appears on screen. But suddenly before the start up screen it shows this: Busy Box v 1.5 (Ubuntu 1: 1.15.31 ubuntu5) built in shell (ash) enter help for a list of built in commands When I type help and press enter, the list of commands appear like below: alias break cd chdir command continue echo eval exec export ... This is my first time so i have no idea what to do. I restarted my pc several times but it happens every time. Please help me. What should I do?

• Microsoft Ramps up Security in Windows 8

  To the average consumer, improvements in the realm of security may not have the most appeal with it comes to a new working environment such as Windows 8. After all, the operating system's future release is expected to offer such flashy bells and whistles as a nifty Metro interface, a tile-based Start screen that provides a quick jump to different functions, and much more. Although these stylish features may be what jumps out at first, it is going to be hard to deny the usefulness and virtual necessity of Windows 8's new security features. The number of consumers who have turned to the intern...

• Moving from local machine to group web development environment

  - by Djave

  I'm a freelancer who currently creates websites locally using something like MAMP to test websites locally before pushing them live with FTP. I'm looking at taking on my first employee, and I would need to be able to work on websites with them simultaneously. Can anyone explain or provide links to some good documentation on team workflow, or some key phrases I should be googling to get started on my set up? Unlike a lot of the stackoverflow community I've never worked in a dev team, large or small as I'm self taught so just need to know where to start. At present I'm thinking I need an extra computer to use as a server, then use Git or some such to version control files on that computer, as well as installing apache on it so it can be viewed by any computers in my current home network. Is this heading down the right track?

• Spending the summer at camp Web Camp, that is

  Microsoft is sponsoring a series of Web Camps this summer. Theyre a series of free two day events being held worldwide, and Im really excited about being taking part. The camp is targeted at a broad range of developer background and experience. Content builds from 101 level introductory material to 200-300 level coverage, but we hit some advanced bits (e.g. MVC 2 features, jQuery templating, IIS 7 features, etc.) that advanced developers may not yet have seen. We start with a lap around ASP.NET...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Generate Multiple Choice Questions [closed]

  - by Daniel

  I'm working on a quiz application that will have a number of multiple choice questions. I'm waiting on the content from the client, but I'm hoping to start testing with some placeholder data for the time being. In order for the tests to be worthwhile, I probably need at least 100 multiple choice questions. I wanted to see if anyone knows of a resource or tool that can generate questions/multiple choice answers or propose another creative way to fill my quiz application with placeholder content. Ultimately the data will be in a MySQL database, but I don't really care what format the sample data is in (Excel, Word, JSON, etc.).

• How should we approach publishing our game from India?

  - by Praveen Sharath

  Me and my friends are developing a game using Java for Windows operating system. We have nearly completed our game. As we feel that the game can make money, we wish to sell it. But in India we don't know any game publishing company. We want to know the following if possible. Will game publishers like BigFishGames.com publish our game even though we are not in USA? We are just students in college. Is it required that we can sell only after we start a company? Is it possible to sign contracts if the publisher wishes to publish our game, while the publisher and developer are in different countries? Thank you

• Unable to set default gateway

  - by GrandMasterFlush

  I'm running Ubuntu server via Hyper-V and have successfully installed it but seem unable to ping the server or ping any other machines on the network from the server. After doing a bit of reading I've noticed that the default gateway isn't set but when I try and set it I keep getting error messages which I can't understand. From this article I've tried ip route add default via 10.0.10.200 Which reports: RTNETLINK answers: Operation not permitted If I try running it prefixed with sudo but it reports: `RNETLINK answers: No such process I've editted /etc/network/interfaces but when I start the machine and type netstat -nr there is nothing listed. Can anyone tell me where I'm going wrong please? EDIT : /etc/network/interfaces contains: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp

• What algorithm can I use to detect simple shapes in a 4x4 matrix?

  - by ion

  I'm working on a simple multiplayer game that receives a random 4x4 matrix from a server and extracts a shape from it. For example: XXOO OXOO XXOX XXOO XOOX and XOOO XXXX OXXX So in the first matrix the shape I want to parse is: oo o oo and the 2nd: oo oo ooo I know there must be an algorithm for this because I saw this kind of behavior on some puzzle games but I have no idea how to go about to detecting them or even where to start. So my question is: How do I detect what shape is in the matrix and how do I differentiate between multiple colors? (it doesn't come only in X and O, it comes in a maximum of 4). Additionally, the shape must be a minimum of 4 blocks.

• Thoughts about MVC

  - by ayyash

  so i figured this one out, as a newcomer to the web development scene from the telecom biz, where we dealt with low level hardware API's, and a C++ fanboy, i tend to be bothered by automagical code, yes i appreciate the effort that went into it, and i certainly appreciate the luxury it provides to get more things done, but i just don't get it. so i decided to change that, and start investigating the new MVC based web apps, and at first it was like hitting a brick wall, i knew MVC from MFC days, so i'm familiar with the pattern, but i just couldn't get my head around the web version of it, till i came to realize the routing, is actually a separate feature to be inspected, much like understanding how LINQ works by better understanding anonymous objects. and so this article serve as an introduction to the following blogs where i share my views of how asp.net routing works, and then leverage that to the MVC level, and play around that field for a bit. as with most of my shared knowladge that may seem trivial to some, but i guess a newcomer's point of view can be useful for some folks out there.

• Imitating Exchange Server's "RBAC AuthZ" in my own application... (is there something similar?)

  - by makerofthings7

  Exchange 2010 has a delegation model where groups of winrm cmdlets are essentally grouped into roles, and the roles assigned to a user. (Image source) This is a great & flexible model considering how I can leverage all the benefits of PowerShell, while using the right low level technologies (WCF, SOAP etc), and requiring no additional software on the client side. (Image source) Question(s) Is there a way for me to leverage Exchange's delegation model in my .NET application? Has anyone attempted to imitate this model? If I must start from scratch, how would I go about imitating this approach?

• Kansas City Developer's Conference

  - by Brian Schroer

  I just found about about / registered for Saturday’s Kansas City Developer’s Conference, and am going to make the drive over from the right side of the state (Hey, no offense, KC – I’m just looking at a map, and St. Louis is on the right side, Kansas City’s on the left). (I’m sure the event’s been mentioned on geekswithblogs several times, but I’m on a “staycation” this week, getting cabin fever, and noticed @leebrandt’s tweet today.) I’m looking forward to some of the presentations in the Agile and Patterns tracks. I’m going to have to get up pretty early Saturday morning to descend from St. Louis to Kansas City (Again, no offense – St. Louis is just at a higher elevation*, that’s all), so if you see a tired-looking guy wandering around wearing a St. Louis Day of .NET shirt, please be nice. I’m not sure how much longer registration will be open, but here’s the link: http://kcdc.eventbrite.com/ *Not true – St. Louis is closer to sea level than Kansas City, but I’ll start my drive from the top of the Arch, OK?

• Why did the upgrade from 11.10 to 12.04 ruin my system?

  - by Jared

  After upgrading from Ubuntu 11.10 to 12.04, when I log in, everything is ruined. It's all black, blank white icons, blank black icons on the start menu, and well, nothing works. If I open up Chromium, it looks as though it's in high contrast mode. Is this a bug? Any ideas what could have happened? Can I get 11.10 back? Some photos (can't connect to network in Ubuntu so I had to take pictures with phone): http://i.stack.imgur.com/2dwKl.jpg http://i.stack.imgur.com/N4nA3.jpg http://i.stack.imgur.com/LNFje.jpg

• Pros and cons of using Grails compared to pure Groovy

  - by shabunc

  Say, you (by you I mean an abstract guy, any guy in your team) have experience of writing and building java web apps, know about filters, servlet mappings and so on, and so on. Also, let us assume you know pretty well any sql db, no matter which one exactly, whether it mysql, oracle or psql. At last, let pretend we know Groovy and its standard libraries, for example all that JsonBuilder and XmlSlurper stuff, so we don't need grails converters. The question is - what are benefits of using grails in this case. I'm not trying to start flame war, I'm just asking to compare - what are ups and downs of grails development compared to pure groovy one. For instance, off the top of my head I can name two pluses - automatic DB mapping and custom gsp tags. But when I want to write a modest app which provides small API for handling some well defined set of data, I'm totally OK with groovy's awesome SQL support. As for gsp, we does not use it at all, so we are not interested in custom tags as well.

• Server Side Developer Prerequisites

  - by Jking

  I am new to server side development and am currently learning node.js. What sort of networking information should I be familiar with to allow for a smooth learning curve with server side development. Could anyone provide resources pertaining to the information required to get into server programming? To give you a better idea of my standpoint: I do not know how a server interacts with a database [Q: How does a NoSQL database, or database in general, communicate with a server?] I am unsure of how a web stack works [Q: I have heard of LAMP but do not know how Apache, MySQL, and PHP interact. Hopefully this applies to other stacks as well. How do the components of a stack work together? Also, is a MEAN stack an alternative, or is it completely irrelevant to this] I have trivial knowledge of internet protocol [however extremely inefficient][Q: What resources are beneficial when learning about networking, and how much/what knowledge should I acquire to program on the server side] I am unsure of what I am unsure of concerning networking information necessary to start development Information on how the client-server model works would be greatly appreciated

• Nvidia problems. I think.

  - by Nate D.

  Let me start off by saying, I've been trying to run Ubuntu on my custom PC for about 2 years. From 10.04 to 12.04, this problem persists. When I try to boot Ubuntu from either a USB stick or a CD, I see the normal Ubuntu splash screen. It looks like it's working, orange dots are moving, but then the screen glitches and freezes. I'm assuming this happens because there are no drivers for my graphics card (Nvidia GeForce 8800, I think). My motherboard has no onboard graphics, nor does it have a VGA out. So, how can I get this working on my system? Can I somehow put the drivers along side the .img on the USB stick? I can boot from my Ubuntu USB stick on my MacBook. In case that helps anyone...

• Best Practice - XML To Excel

  - by MemLeak

  I've to read a big XML file with a lot of information. Afterwards I extract the needed information (~20 Points(columns) / ~80 relevant Data (rows, some of them with subdatasets) and write them out in a Excel File. My Question is how to handle the extraction (of unused Data) part, should I copy the whole file and delete the unused parts, and then write it to excel or is it a good approach to create Objects for each column? should I write the whole xml to excel and start to delete rows in excel? What would be performant and a acceptable solution?

• Cannot escape character '@' in fstab file

  - by ubuntico

  I want to attach remote FTP directory as a local directory in my system. I will use curlftpfs line in the fstab file , but to login I have to pass my user name and password. The user name has a special character (@) and it needs to be escaped via octal ascii code. The octal ascii for '@' is 100. But when I try to enter the following into the FSTAB file, curlftpfs#myself\100myself.com:ftpPassword@ftp://ftp.mysite.com /mnt/somedir I get an error saying Error connecting to ftp: Couldn't resolve host 'myself.com:ftpPassword@ftp://ftp.mysite.com' The fstab does not recognize escaped symbol @ (\100) and thinks that the FTP site should start immediately after the @ symbol (just like I haven't escaped it). Can someone help? Why I cannot escape @, when it can be done for space character, for example?

• How to make Jetty webserver listen on port 80?

  - by Jonas

  I would like to use Jetty as a webserver. I have edited the configuration file at /etc/default/jetty and set: # change to 0 to allow Jetty start NO_START=0 # Listen to connections from this network host # Use 0.0.0.0 as host to accept all connections. JETTY_HOST=0.0.0.0 Now I can reach the Jetty webserver at http://192.168.1.10:8080 but I would like to have Jetty listening on port 80. I have tried this setting in the same configuration file: # The network port used by Jetty JETTY_PORT=80 and then restart Jetty with sudo service jetty restart but it doesn't work. How can I change so that the Jetty webserver is listening on port 80?

• With respect to gnome-session, what is a "component"?

  - by Alistair Buxton

  Under /usr/share/gnome-session/sessions are files which describe the different types of sessions available from gnome-session. In these files is a list of required components, eg for shell: RequiredComponents=gnome-shell;gnome-settings-daemon; or for fallback: RequiredComponents=gnome-panel;gnome-settings-daemon; This appears to be a list of executables, but it is not. If I change gnome-panel to some other type of panel, the session does not start, and I see the following errors in ~/.xsession-errors: gnome-session[2003]: WARNING: Unable to find required component 'xfce4-panel' So my question: What is a component, how are they defined, and where does gnome-session look for them?
