• Black screen with blinking cursor after dual boot install 14.04

  - by chillstream

  I have just installed Ubuntu 14.04 on my toshiba laptop along side Windows 7. When the menu comes up to choose which OS to boot into, I can easily boot into Windows 7. I cannot successfully boot into Ubuntu. All I get is a blinking cursor on a black/purple screen. I attempted the nomodeset trick, which was a bit more successful. I got a screen with a lot of code, but then it stopped with a blinking cursor at the bottom and wouldn't load anymore. As a last resort, would returning my laptop to factory settings get rid of linux and the partitions made to the drive? I already did this to my laptop when it was just windows, which is why I thought I might as well try to add Ubuntu. But it's a lengthy process, and if it won't get rid of the partitions and ubuntu, I won't bother. I appreciate any help ~many thanks

• How do I install ubuntu 12.04 over windows HP

  - by Cakemix

  I have an HP Desktop AMD 64 6-core processor 10GB RAM 1.5TB HDD and Windows 7 installed. I downloaded the 12.04 ISO and burned to a DVD. I want to install Ubuntu over Windows. I have recovery CD's made in case Ubuntu isn't for me and my family. During the install it says No root file system is defined please correct this from the partitioning table. In the box where I should be able to choose a partition, none are available to choose from, it is blank. I know that HP has decided to use 4 partitions. How do I go about deleting all the partitions using the LiveCD? I've never used GParted before and am a bit lost when it comes to anything to do with partitions.

• Chessin's principles of RAS design

  - by user12608173

  In late 2001 I developed an internal talk on designing hardware for easier error injection, prevention, diagnosis, and correction. (This talk became the basis for my paper on injecting errors for fun and profit.) In that talk (but not in the paper), I articulated 10 principles of RAS design, which I list for you here: Protect everything Correct where you can Detect where you can't Where protection not feasible (e.g., ALUs), duplicate and compare Report everything; never throw away RAS information Allow non-destructive inspection (logging/scrubbing) Allow non-destructive alteration (injection) (that is, only change the bits you want changed, and leave everything else as is) Allow observation of all the bits as they are (logging) Allow alteration of any particular bit or combination of bits (injection) Document everything Of course, it isn't always feasible to follow these rules completely all the time, but I put them out there as a starting point.

• At what point asynchronous reading of disk I/O is more efficient than synchronous?

  - by blesh

  Assuming there is some bit of code that reads files for multiple consumers, and the files are of any arbitrary size: At what size does it become more efficient to read the file asynchronously? Or to put it another way, how small must a file be for it to be faster just to read it synchronously? I've noticed (and perhaps I'm incorrect) that when reading very small files, it takes longer to read them asynchronously than synchronously (in particular with .NET). I'm assuming this has to do with set up time for things like I/O Completion Ports, threads, etc. Is there any rule of thumb to help out here? Or is it dependent on the system and the environment?

• System Requirement Checking

  - by gl3829

  I am working on a game and want to strengthen its requirement checking to ensure that it can run successfully. Therefore, I am looking for information on what is useful to check before starting the game. As a simple example, Why check for a specific amount of memory? Should I as a game developer ensure a minimum amount of memory? I feel this information is usually skipped in many books and resources but is critical to be able to deliver a game that will run on many machines. I would appreciate if you answered with what you check in the system, why you check it and if you have a good resource about it, please include. Just to be a bit more specific, I'm developing in Windows.

• configuring separate X screens instead of TwinView

  - by fimre

  My Sony Vaio laptop is connected to an external Samsung monitor and my nVidia driver is configured in TwinView mode. Everything is OK with this, however, I can not adjust my displays individually so at the moment my external display is a little bit darker which disturbs me a lot. I tried the Separate X Screen mode but after restart, my laptop display was white with a black x sign mouse pointer and the external display normal desktop. Is it a bug or something I missed? The idea is that using Separate X Screen mode, I could adjust my displays individually. I would really appreciate someone would guide me out of this situation. Thanx in adv..

• Why can't I update to 11.04?

  - by user285982

  I am using Ubuntu 10.10 64 bit, and I can browse the internet fine. I am typing this using the machine. When I attempt to use the Ubuntu Update Manager to update to 11.04, I get this error message: Failed to Fetch Fetching the upgrade failed.There may be a network problem. And when I try to change servers, here is what I get: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/maverick/main/source/Sources.gz 404 Not Found [IP: 91.189.91.15 80] It repeats with other lines, 404 not found. Some index files failed to download, they have been ignored, or old ones used instead. Any ideas?

• Can I publish my game code under GPL? How? What about an engine?

  - by Bane

  I made a game, and I am currently making a game engine. I want them both to be completely free and open source. What license should I choose? I was reading a bit on GPL, but that seems to be more suited for system code and libraries, AFAIK, as it doesn't permit the use of code for proprietorial software - which, in turn, implies that the code can be used in the first place. I can see that, obviously, game engines can be considered libraries, and therefor be used, but what about game code? Is there an alternative to GPL?

• Algorithm for Learning development

  - by user9057

  Hi all, This is a fairly general question. I know a bit of Perl and Python and I am looking to learn programming in more depth so that once I get the hang of it I can start developing applications and then websites. I would like to know of an algorithm (sequence of steps :)) that could describe my approach towards learning programming in general. I have posted small questions on Perl/Python and I have recieved great help from everyone. Note:- I am not in a hurry to learn. I know it takes time and that's fine. Please give any suggestions you think are valid. Also, please don't push me to learn Lisp, Haskell etc - I am a beginner.

• How To Sideload Modern Apps on Windows 8

  - by Chris Hoffman

  The average Windows 8 user can only download apps that Microsoft has approved from the Windows Store. Windows 8 offers two ways to sideload unapproved apps, which are intended for developers and businesses with internal apps. These methods cannot be used by the average geek to install unapproved apps from the web. Windows 8’s new interface takes the Apple iOS approach of forbidding unapproved software, not the Android approach of allowing all users to enable sideloading. Note: This only applies to Modern apps in the new Windows 8 interface, not on the desktop. Windows desktop applications can be installed normally. However, you can’t install any desktop applications on devices running Windows RT. Why Does 64-Bit Windows Need a Separate “Program Files (x86)” Folder? Why Your Android Phone Isn’t Getting Operating System Updates and What You Can Do About It How To Delete, Move, or Rename Locked Files in Windows

• Nexus S 4g not detected by computer

  - by Newbie in over his head

  A little bit of a disclaimer, I have very little knowledge of the correct terminology for some of the things I'm going to ask about, and I apologize in advance I have a Nexus S 4g phone that is, at the moment of writing, connected to my 11.10 computer through its USB charger cable. In the past, connecting the phone like this has allowed me to transfer files between my computer and my phone; I'm able to get my music onto my phone, and my photos onto my computer, for example. For some reason, this has stopped working. My phone still charges its battery when connected to the computer, but neither the computer nor the phone recognized that they are connected. Is there something I can do to get the phone and the computer to detect each other? I don't know how to fix this, and it's more than a little frustrating. Any help would be greatly appreciated.

• What are the challenges and benefits of writing games with a functional language?

  - by McMuttons

  While I know that functional languages aren't the most commonly used for game writing, there are a lot of benefits associate with them that seem like they would be interesting in any programming context. Especially the ease of parallelization I would think could be very useful as focus is moving toward more and more processors. Also, with F# as a new member of the .NET family, it can be used directly with XNA, for example, which lowers the threshold quite a bit, as opposed to going with LISP, Haskell, Erlang, etc. If anyone has experience writing games with functional code, what has turned out to be the positives and negatives? What was it suited for, what not? Edit: Finding it hard to decide that there's a single good answer for this, so it's probably better suited as a community wiki post.

• Is it a bad practice to have an interface to define constants?

  - by FabianB

  I am writing a set of junit test classes in java. There are several constants, for example strings that I will need in different test classes. I am thinking about an interface that defines them and every test class would implement it. The benefits I see there are: easy access to constants: "MY_CONSTANT" instead of "ThatClass.MY_CONSTANT" each constant defined only once Is this approach rather a good or bad practice? I feel like abusing the concept of interfaces a little bit. You can answer generally about interfaces/constants, but also about unit tests if there is something special about it.

• No sound/audio after resuming from sleep

  - by hansvonaachen

  I've made a fresh UEFI install of Ubuntu 13.10 (64 bit) on a Lenovo Ideapad Z510 laptop with Intel i5 4200M processor. Ubuntu is the only OS installed on the computer, secure boot disabled. Everythings works fine (backlight issue fixed after editing rc.local file), the only minor trouble I have is resuming the laptop from "sleep" mode. If I close the lid and then wake the laptop opening it again, there is no audio/sound. I need to restart the computer (not even logging out helps). If I suspend the computer in a graphical way (not closing the lid): gearwheel in top right of the screen -- suspend and wake it up/turning on, audio works with no issues. Ideas how to fix this? Thanks!

• Cannot connect to wifi after downloading 12.04, repeated prompts for password

  - by Daytown3487

  I have had this OS for a little bit but this is my first upgrade and my first issue I am trying to deal with without my buddy who got my on Ubuntu in the first place (who is on the other side of the country.) I am running an IBM Lenovo T400 Thinkpad that had 11.10 on it and worked flawless. I upgraded to 12.04 a few weeks back and I have not been able to connect to the wifi in my home or anywhere for that matter. I have been trying to mess with it through reading the forums and am not quite sure what my problem is. I am running off of Fios Internet and the wifi keep disconnecting and prompts me to retype the password for reconnecting. If you guys could give me a step by step process of how I should go about fixing this I would GREATLY appreciate it!

• Why Gsettings isn't enough to reset my nautilus settings?

  - by berdario

  I'm trying to narrow down a bug (to eventually report it or give up if it'll turn out that resetting a simple setting will be enough to get rid of it) I noticed that with a brand new user the bug doesn't pop up so I tried to reset the config of my user's nautilus I renamed .config/nautilus I renamed .nautilus2 (strange name... why the 2?) and I did a gsettings reset-recursively org.gnome.nautilus strangely enough, it didn't work: I previously set up to use my home as the desktop folder, and now the key has correctly been resetted $gsettings get org.gnome.nautilus.preferences desktop-is-home-dir false and yet on my desktop I see the contents of my home folder (meaning that the settings have not been resetted) I know that with the transition to gtk3 there've been lots of changes (before I should've used gconf... but now there's dconf and gsettings), so there're quite a bit of question about nautilus... but these unfortunately now seem to be outdated

• How to choose a good namespace name? [Linguistically]

  - by Kees C. Bakker

  English in not my native language, therefore it is a little more difficult to pick a good name for a namespace. One example to make you see my problem a bit better: We have a set of classes that have to do with the way a company is organized (we can create organizational charts with it). Currently the namespace is CFW.CoreSystem.Organizational. Is this a good name? What is linguistically the best way to name a namespace? (CFW.CoreSystem.Configuration is better than CFW.CoreSystem.Configurables). [Moved it from StackOverflow]

• nicstat update - version 1.92

  - by user12608033

  Another minor nicstat release is now available. Changes for Version 1.92, October 2012 Common Added "-M" option to change throughput statistics to Mbps (Megabits per second). Suggestion from Darren Todd. Fixed bugs with printing extended parseable format (-xp) Fixed man page's description of extended parseable output. Solaris Fixed memory leak associated with g_getif_list Add 2nd argument to dladm_open() for Solaris 11.1 Modify nicstat.sh to handle Solaris 11.1 Linux Modify nicstat.sh to see "x86_64" cputype as "i386". All Linux binaries are built as 32-bit, so we do not need to differentiate these two cpu types. Availability nicstat source and binaries are available from sourceforge.

• And just like that, there went February

  - by Enrique Lima

  The best intentions were having me at perhaps posting more than twice a month, and here we are and … well it has been busy. There has been a lot of SharePoint 2010 already in this first number of weeks of the year, a good amount of TFS 2010, but even better working quite actively on two topics that I enjoy quite a bit … Windows Azure and Application Lifecycle Management.  And there is more to come around those two. Through the influencers program with Geekswithblogs and Discountasp.net I got access to a hosted TFS solution that I am currently testing and will be posting my findings and documenting a good amount of information on that process. Another great resource has been fpweb.net, and there will be more details on this too.  Pretty exciting stuff! That is what is going on and what will be coming on here shortly.

• New Window Via JavaScript Clears Parent

  - by Bunch

  This is not a new item at all but I came across it recently. For an app I had been using some JavaScript like: javascript:window.open(someurl.aspx here) to open a new window via a button. That bit of code had been working great in several other apps. Then in one app that same code decided to open the new window correctly while clearing the parent of everything but [object]. The fix ended up being simple, change the javascript to: javascript:void(window.open(someurl.aspx here); Then it worked like I thought it should. Tags: ASP.Net, JavaScript

• Setting up fastcgi on an Ubunutu server (socket file permissions issue)

  - by gray alien

  I am trying to set up mod_fcgid on my server. Part of the requirement is that Apache needs to create a socket file for mod_fcgid. I specified the folder for Apache to write the socket data to: /var/run/apache2/fcgid I then specified this file in my fcgid.conf file as follows: SocketPath /var/run/apache2/fcgid/sock I then changed the owner of the folder to www-data (the apache user) and gave the owner full permissions to the folder and its contents. I was able to run my test fcgi app then. When I rebooted the machine, y fastcgi app no longer worked. After some investigation, I found that ownership of /var/run/apache2/fcgid has been reset to root, and with permission reset to 700 I have the following questions: Is there something specific about the /var/run folder? why is the permissions being reset after a reboot? Should I move my socket file to another location (in case root automatically takes ownership of contents in this folder for security reasons?) I am running Ubuntu 10.0.4 LTS 64 bit

• Best Graphics card (Setup) for three, high-res monitors attached to desktop

  - by nomrasco

  I have been looking around a little bit, but most of the discussions are about problems with already existing systems (particular graphics card and setup etc.). I would like to ask what would be the best option for me if I want to build powerful desktop with triple monitor setup. I have one Dell UltraSharp U2713HM (27 inches, 2560x1440) and I was thinking about getting two more. Would it be possible to have those three working with ubuntu (kubuntu) on any graphics card out there today? What is the best option if it comes to choosing particular model? Should I use proprietary drivers or some open sourced ones? I am not a gamer. I mostly develop on my machines and running some computational tasks, but I would rather like to spend some more money and have setup where I don't see any lags :) thank You very much in advance!

• Two users sharing the same computer

  - by Pitto

  I need to share my pc with a friend of mine living in India. His pc is a p4 and he needs a bit of horsepower for calculation. Since I have an i5 I thought to let him vnc and use it but this would not allow me to use the computer at the same time. Is there a way to use the computer at the same time with different users? I've read Xorg is able to do this but I am not sure is the best solution nor I can implement it. We have Ubuntu 12.04 64bit on the i5 side and Ubuntu 12.04 32bit on the p4 side. Thank you for your kind help.
