  • Laptop resumes from suspend while lid is closed

    - by Gus
    I have a Dell Studio 15 and I am running Ubuntu 10.10. When I close my lid or select the suspend option, the machine suspends as indicated by the slowly pulsing power indicator. I'll put the machine in my bag and after a while it seems that the machine resumes, at least I think. When ever I go to get it, it's overheated and the system cannot resume. I am guessing that the processor resets in this overheat condition, but heat is still generated. This has happened about three times and I'm getting worried that I'll end up damaging the machine. How can I diagnose why the system is resuming from suspend? Can I force it to never resume from suspend if the lid is down?

  • Failed to start up after upgrading software

    - by Landy
    I asked this question in SuperUser one hour ago, then I know this community so I moved the question here... I've been running Ubuntu 10.10 in a physical x86-64 machine. Today Update Manager reminded me that there are some updates to install and I confirmed the action. I should had read the update list but I didn't. I can only remember there is an update about cups. After the upgrading, Update Manager requires a restart and I confirmed too. But after the restart, the computer can't start up. There are errors in the console. Begin: Running /scripts/init-premount ... done. Begin: Mounting root file system ... Begin: Running /scripts/local-top ... done. [xxx]usb 1-8: new high speed USB device using ehci_hcd and address 3 [xxx]usb 2-1: new full speed USB device using ohci_hcd and address 2 [xxx]hub 2-1:1.0: USB hub found [xxx]hub 2-1:1.0: 4 ports detected [xxx]usb 2-1.1: new low speed USB device using ohci_hcd and address 3 Gave up waiting for root device.

(initramfs)[cursor is here] At the moment, I can't input anything in the console. The keyboard doesn't work at all. What's wrong? How can I check boot args or "root=" as suggested? How can I fix this issue? Thanks. =============== PS1: the /dev/sda1 is type ext4 (rw,nosuid,nodev) PS2: the /dev/sda1 can be mounted and accessed successfully under SUSE 11 SP1 x64. PS3: From this link, I think the keyboard doesn't work because the USB driver is not loaded at that time.

  • Apple's Java Mac OS X 2012-006 Update

    - by Sharon Zakhour
    The recent Java Mac OS X 2012-006 update from Apple removes the Apple Java 6 plug-in from your Mac. The Mac OS X Install FAQ will be updated with the next 7u release, but you may find the following information useful in the meantime. Q: I have installed Java for OS X 2012-006 and Apple Java 6 can no longer be used for applets or Web Start. How do I get it back? A: The Java for OS X 2012-006 update from Apple uninstalls the Apple-provided Java applet plug-in from all web browsers. You can download the latest version of Java from Oracle, which has improved security, reliability and compatibility. If you prefer to continue using Apple's Java 6 plug-in, you can follow the steps provided in How to re-enable the Apple-provided Java SE 6 applet plug-in and Web Start functionality. Q: After installing Java for OS X 2012-006, can I continue to use Apple's Java 6 alongside the OS X JDK or JRE for Java 7? A: If you want to continue to develop with Java 6 in a Terminal window you can modify the startup script for your favorite command environment. For bash, use this: export JAVA_HOME=`/usr/libexec/java_home -v 1.6` Some applications use /usr/bin/java to invoke Java. After installing Java for OS X 2012-006, /usr/bin/java will find the newest JDK installed, and will use that for all of the Java related command line tools in /usr/bin. You may need to modify those applications to find Java 6, or contact the developer for a newer version of the application. Also, this update removes Apple provided Java Preferences app. For more information on how to determine the default version of Java on your system, see Determining the Installed Version of the JRE in the JRE 7 Installation for Mac OS X page.

  • Design documents as part of Agile

    - by syrion
    At my workplace, we face a challenge in that "agile" too often has meant "vague requirements, bad acceptance criteria, good luck!" We're trying to address that, as a general improvement effort. So, as part of that, I am proposing that we generate design documents that, above and beyond the user story level, accurately reflect the outcome of preliminary investigations of the effect of a given feature within the system and including answers to questions that we have asked the business. Is there an effective standard for this? We currently face a situation where a new feature may impact multiple areas in our "big ball of mud" system, and estimates are starting to climb due to this technical debt. Hopefully more thoughtful design processes can help.

  • How to prepare WiFi for an on-stage demo?

    - by Jeremy White
    Today at WWDC, Steve Jobs gave his keynote and ended up having a failure on-stage when connecting to WiFi. Google had a similar issue a few weeks ago in the same conference center. Please reference the following article for more information. http://news.cnet.com/8301-31021_3-20007009-260.html I am looking for information on how to best prepare a demo which uses a closed wireless network in front of a large audience. Note that the network will be closed, and will not require internet access. What steps can I take to prevent interference from existing WiFi, Bluetooth, etc? How can I best prevent curious/malicious people from trying to intrude on my WiFi network? I am open to recommendations on specific models of routers.

  • C# WebForms and Ninject

    - by ipohfly
    I'm re-working on the design of an existing application which is build using WebForms. Currently the plan is to work it into a MVP pattern application while using Ninject as the IoC container. The reason for Ninject to be there is that the boss had wanted a certain flexibility within the system so that we can build in different flavor of business logic in the model and let the programmer to choose which to use based on the client request, either via XML configuration or database setting. I know that Ninject have no need for XML configuration, however I'm confused on how it can help to dynamically inject the dependency into the system? Imagine I have a interface IMember and I need to bind this interface to the class decided by a xml or database configuration at the launch of the application, how can I achieve that?

  • Is Moving Entity Framework objects over a webservice really the best way?

    - by aceinthehole
    I've inherited a .NET project that has close to 2 thousand clients out in the field that need to push data periodically up to a central repository. The clients wake up and attempt to push the data up via a series of WCF webservices where they are passing each entity framework entity as parameter. Once the service receives this object, it preforms some business logic on the data, and then turns around and sticks it in it's own database that mirrors the database on the client machines. The trick is, is that this data is being transmitted over a metered connection, which is very expensive. So optimizing the data is a serious priority. Now, we are using a custom encoder that compresses the data (and decompresses it on the other end) while it is being transmitted, and this is reducing the data footprint. However, the amount of data that the clients are using, seem ridiculously large, given the amount of information that is actually being transmitted. It seems me that entity framework itself may be to blame. I'm suspecting that the objects are very large when serialized to be sent over wire, with a lot context information and who knows what else, when what we really need is just the 'new' inserts. Is using the entity framework and WCF services as we have done so far the correct way, architecturally, of approaching this n-tiered, asynchronous, push only problem? Or is there a different approach, that could optimize the data use?

  • Application development : method to manage backgound process

    - by Simon Dubois
    I am developing an application with different behavior depending on the arguments : - "-config" starts a Gtk window to change options, start and close the daemon. - "-daemon" starts a background process that does something every X minutes. I already know how to use fork/system/exec etc... But I would like to know the main logic of such application to : - restart or refresh the daemon when configuration change. - keep only one instance of the daemon. I have red that killing the daemon to restart it is not a clean way to do. How other applications do ? (ubuntuone, weather forecast, rss feed working with notification area) Thanks for your help. PS : I don't want to create a system-wide daemon, just a user application with a background process.

  • How to install hardware drivers for my laptop

    - by John Flisk
    Everytime I change the OS I usually format my laptop. It is an HP tx-2 Touchsmart. It has a touchscreen and additional hardware that isn't working (i.e. volume control buttons and the network discovery) If I was on windows I would just download the hardware drivers from the HP website. How do I go about installing the software for the built-in hardware of my laptop? I am new to the community and I really want to get this computer working like it used to, to get the full Ubuntu experience. Please direct me, thank you.

  • Periodic clicking sound from PC speaker

    - by John J. Camilleri
    After an update some months ago, my laptop has begun making a low, repeated clicking sound every few seconds. It is not being generated through the regular sound system, as altering the volume and even muting the sound does not make any difference. My regular audio works fine, by the way, so I am guessing this is some sort of PC speaker, since I cannot hear the click when I listen through regular headphones. Strangely, when I open the sound settings dialog the click magically disappears. I don't need to change any settings; if I simply leave the dialog open in the background then the problem disappears. Any ideas what this could be? I am running regular Ubuntu 12.04, and this is the output from lspci -v | grep -A7 -i "audio": 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Subsystem: Acer Incorporated [ALI] Device 0349 Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at 54200000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel Kernel modules: snd-hda-intel

  • How to completely shutdown Ati card

    - by Celso
    I would like to know how do i prevent my Ati card from turning on when i enter on ubuntu 11.10. My bios only lets-me shutdown intel hd card or leave the both on but i want to know if is possbible to completely shutdown without having to access to the bios.( if is possible to turn of without using Vgaswitcheroo even better!) My system is: Acer 3820tg-- intel core i3 350M, 2.26 Ghz L3, Ati Mobility Radeon HD 5470 up to 2138 MB hyper memory, 13,3" HD LED LCD, 4gb DDR3, SSD corsair 60GB sata 2. EDIT: I now know what is missing on the answers! I edited /etc/rc.local file and added the next lines: Sleep 3 echo ON /sys/kernel/debug/vgaswitcheroo/switch echo IGD /sys/kernel/debug/vgaswitcheroo/switch echo OFF /sys/kernel/debug/vgaswitcheroo/switch And then save the file and restart. It should be possible to use only the intel card now. By the way, i didn't blacklisted the radeon driver because doing it make my ati card wake up. (use it at your own risk. i only tested in my system)

  • Browser privacy improvement implications for websites

    - by phq
    On https://panopticlick.eff.org/ EFF let you test the number of uniquely identifying bits that the browser gives a website. Among these are HTTP header fields such as User-Agent, Accept, Accept-Language and later perhaps ETAG and If-Modified-Since. Also there is a lot of Information that javascript can get from the browser such as time-zone, screen resolution, complete list of fonts and plugins available. My first impression is, is all this information really usable/used on a majority of all websites? For example, how many sites does really send different content-types depending on the http accept header, or what fonts are available(I thought css had taken care of this)? Let's say of these headers/js functionality on day would be gone. Which ones would; never be noticed they were gone? impact user experience? impact server performance? immediately reimplemented because the Internet cannot work without it? Extra credit for differentiating between what can be done, what should be done and what is done in most situations.

  • How can I create a symlink to the location that Ubuntu 10.10 mounts a CD?

    - by Michael Curran
    In Ubuntu 10.10, when I insert a CD or DVD into my optical drive, the system mounts the CD in a folder called /media/XYZ where XYZ is the disk's label. This has cause problems with Wine, as in order for an application to verify that an application's CD is present, Wine uses a symlinks to point to a mounted CD's folder. In this case, that folder must be /media/XYZ, but when using a different application, the folder would be different. I would like to know if there is a way to create a symlink that will always point to the mounted folder from a given /dev/cdrom* device, or how to force the system to always mount CDs to the same address (i.e. /media/cdrom).

  • What would I do to figure out why Suspend sometimes crashes?

    - by Isaac
    Something is causing suspend crash occasionally. When it does crash, the system freezes with a black screen and stays on, not suspending. This makes me have to hold the power button until the system shuts down. One setting difference I have from most people is, I don't use the option that lets you suspend when the laptop lid is closed. So opening and closing the laptop lid has no actions. I like to press suspend manually. Could this preference change be the cause? How can I start looking for what's causing the crash, since the crash doesn't display errors?

  • XUbuntu 12.04 sound becomes distorted on ASUS-computers

    - by Slava Fomin II
    On my XUbuntu 12.04 Desktop from time to time audio becomes distorted, not the audio from some specific applications but every possible sounds are very noisy and barely recognizable. Then i go to: Applications Menu Multimedia PulseAudio Volume Control "Configuration"-tab and change Built-in Audio's Profile from my current profile to something else. After that audio becomes normal, until it breaks again and i have to repeat these steps. It's happening on two different computers: one is an ASUS-based Desktop and other is ASUS notebook. Maybe it's related to some common motherboard audio components. Motherboard is: ASUS P8P67 EVO REV 3.0 Netbook is: ASUS EEPC VX6 Any help will be much appreciated = )

  • Better way to load level content in XNA?

    - by user2002495
    Currently I loaded all my assets in XNA in the main Game class. What I want to achieve later is that I only load specific assets for specific levels (the game will consist of many levels). Here is how I load my main assets into the main class: protected override void LoadContent() { spriteBatch = new SpriteBatch(GraphicsDevice); plane = new Player(Content.Load<Texture2D>(@"Player/playerSprite"), 6, 8); plane.animation = "down"; plane.pos = new Vector2(400, 500); plane.fps = 15; Global.currentPos = plane.pos; lvl1 = new Level1(Content.Load<Texture2D>(@"Levels/bgLvl1"), Content.Load<Texture2D>(@"Levels/bgLvl1-other"), new Vector2(0, 0), new Vector2(0, -600)); CommonBullet.LoadContent(Content); CommonEnemyBullet.LoadContent(Content); } protected override void UnloadContent() { } protected override void Update(GameTime gameTime) { if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); plane.Update(gameTime); lvl1.Update(gameTime); foreach (CommonEnemy ce in cel) { if (ce.CollidesWith(plane)) { ce.hasSpawn = false; } foreach (CommonBullet b in plane.commonBulletList) { if (b.CollidesWith(ce)) { ce.hasSpawn = false; } } ce.Update(gameTime); } LoadCommonEnemy(); base.Update(gameTime); } private void LoadCommonEnemy() { int randY = rand.Next(-600, -10); int randX = rand.Next(0, 750); if (cel.Count < 3) { cel.Add(new CommonEnemy(Content.Load<Texture2D>(@"Enemy/Common/commonEnemySprite"), 7, 2, "left", randX, randY)); } for (int i = 0; i < cel.Count; i++) { if (!cel[i].hasSpawn) { cel.RemoveAt(i); i--; } } } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.Black); spriteBatch.Begin(); lvl1.Draw(spriteBatch); plane.Draw(spriteBatch); foreach (CommonEnemy ce in cel) { ce.Draw(spriteBatch); } spriteBatch.End(); base.Draw(gameTime); } I wish to load my players, enemies, all in Level1 class. However, when I move my player & enemy code into the Level1 class, the gameTime returns null. Here is my Level1 class: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Audio; using Microsoft.Xna.Framework.Content; using Microsoft.Xna.Framework.Graphics; using Microsoft.Xna.Framework.Media; using Microsoft.Xna.Framework.Input; using SpaceShooter_Beta.Animation.PlayerCollection; using SpaceShooter_Beta.Animation.EnemyCollection.Common; namespace SpaceShooter_Beta.Levels { public class Level1 { public Texture2D bgTexture1, bgTexture2; public Vector2 bgPos1, bgPos2; public float speed = 5f; Player plane; public Level1(Texture2D texture1, Texture2D texture2, Vector2 pos1, Vector2 pos2) { this.bgTexture1 = texture1; this.bgTexture2 = texture2; this.bgPos1 = pos1; this.bgPos2 = pos2; } public void LoadContent(ContentManager cm) { plane = new Player(cm.Load<Texture2D>(@"Player/playerSprite"), 6, 8); plane.animation = "down"; plane.pos = new Vector2(400, 500); plane.fps = 15; Global.currentPos = plane.pos; } public void Draw(SpriteBatch sb) { sb.Draw(bgTexture1, bgPos1, Color.White); sb.Draw(bgTexture2, bgPos2, Color.White); plane.Draw(sb); } public void Update(GameTime gt) { bgPos1.Y += speed; bgPos2.Y += speed; if (bgPos1.Y >= 600) { bgPos1.Y = -600; } if (bgPos2.Y >= 600) { bgPos2.Y = -600; } plane.Update(gt); } } } Of course when I did this, I delete all my player's code in the main Game class. All of that works fine (no errors) except that the game cannot start. The debugger says that plane.Update(gt); in Level 1 class has null GameTime, same thing with the Draw method in the Level class. Please help, I appreciate for the time. [EDIT] I know that using switch in the main class can be a solution. But I prefer a cleaner solution than that, since using switch still means I need to load all the assets through the main class, the code will be A LOT later on for each levels

  • Free-flow Alternative to Powerpoint?

    - by Nick Klauer
    So I've been digging around the net trying to find a good set of alternatives to Powerpoint. Part of my interest is that I found one, Prezi, that I liked for it's free-form style. Part of the power of it was that I can zoom out and select any part of the presentation to continue from and it feels much like a mind map or association of thoughts. Are there any other tools that offer anything similar in vein to this way of presenting material? I'm looking for something that just pops differently than a death-by-powerpoint-style presentation, so I would be happy to find tools that help present information in more fluid styles. It doesn't have to mirror Prezi, and I wouldn't want that, but after seeing what Prezi does, I have to think there are other ways of presenting information to a group of people than one square slide at a time.

  • How to make a great functional specification

    I am going to start a little side project very soon, but this time i want to do not just the little UML domain model and case diagrams i often do before programming, i thought about making a full functional specification. Is there anybody that has experience writing functional specifications that could recommend me what i need to add to it? How would be the best way to start preparing it? Here i will write down the topics that i think are more relevant: Purpose Functional Overview Context Diagram Critical Project Success Factors Scope (In & Out) Assumptions Actors (Data Sources, System Actors) Use Case Diagram Process Flow Diagram Activity Diagram Security Requirements Performance Requirements Special Requirements Business Rules Domain Model (Data model) Flow Scenarios (Success, alternate…) Time Schedule (Task Management) Goals System Requirements Expected Expenses What do you think about those topics? Shall i add something else? or maybe remove something?

  • What Precalculus knowledge is required before learning Discrete Math Computer Science topics?

    - by Ein Doofus
    Below I've listed the chapters from a Precalculus book as well as the author recommended Computer Science chapters from a Discrete Mathematics book. Although these chapters are from two specific books on these subjects I believe the topics are generally the same between any Precalc or Discrete Math book. What Precalculus topics should one know before starting these Discrete Math Computer Science topics?: Discrete Mathematics CS Chapters 1.1 Propositional Logic 1.2 Propositional Equivalences 1.3 Predicates and Quantifiers 1.4 Nested Quantifiers 1.5 Rules of Inference 1.6 Introduction to Proofs 1.7 Proof Methods and Strategy 2.1 Sets 2.2 Set Operations 2.3 Functions 2.4 Sequences and Summations 3.1 Algorithms 3.2 The Growths of Functions 3.3 Complexity of Algorithms 3.4 The Integers and Division 3.5 Primes and Greatest Common Divisors 3.6 Integers and Algorithms 3.8 Matrices 4.1 Mathematical Induction 4.2 Strong Induction and Well-Ordering 4.3 Recursive Definitions and Structural Induction 4.4 Recursive Algorithms 4.5 Program Correctness 5.1 The Basics of Counting 5.2 The Pigeonhole Principle 5.3 Permutations and Combinations 5.6 Generating Permutations and Combinations 6.1 An Introduction to Discrete Probability 6.4 Expected Value and Variance 7.1 Recurrence Relations 7.3 Divide-and-Conquer Algorithms and Recurrence Relations 7.5 Inclusion-Exclusion 8.1 Relations and Their Properties 8.2 n-ary Relations and Their Applications 8.3 Representing Relations 8.5 Equivalence Relations 9.1 Graphs and Graph Models 9.2 Graph Terminology and Special Types of Graphs 9.3 Representing Graphs and Graph Isomorphism 9.4 Connectivity 9.5 Euler and Hamilton Ptahs 10.1 Introduction to Trees 10.2 Application of Trees 10.3 Tree Traversal 11.1 Boolean Functions 11.2 Representing Boolean Functions 11.3 Logic Gates 11.4 Minimization of Circuits 12.1 Language and Grammars 12.2 Finite-State Machines with Output 12.3 Finite-State Machines with No Output 12.4 Language Recognition 12.5 Turing Machines Precalculus Chapters R.1 The Real-Number System R.2 Integer Exponents, Scientific Notation, and Order of Operations R.3 Addition, Subtraction, and Multiplication of Polynomials R.4 Factoring R.5 Rational Expressions R.6 Radical Notation and Rational Exponents R.7 The Basics of Equation Solving 1.1 Functions, Graphs, Graphers 1.2 Linear Functions, Slope, and Applications 1.3 Modeling: Data Analysis, Curve Fitting, and Linear Regression 1.4 More on Functions 1.5 Symmetry and Transformations 1.6 Variation and Applications 1.7 Distance, Midpoints, and Circles 2.1 Zeros of Linear Functions and Models 2.2 The Complex Numbers 2.3 Zeros of Quadratic Functions and Models 2.4 Analyzing Graphs of Quadratic Functions 2.5 Modeling: Data Analysis, Curve Fitting, and Quadratic Regression 2.6 Zeros and More Equation Solving 2.7 Solving Inequalities 3.1 Polynomial Functions and Modeling 3.2 Polynomial Division; The Remainder and Factor Theorems 3.3 Theorems about Zeros of Polynomial Functions 3.4 Rational Functions 3.5 Polynomial and Rational Inequalities 4.1 Composite and Inverse Functions 4.2 Exponential Functions and Graphs 4.3 Logarithmic Functions and Graphs 4.4 Properties of Logarithmic Functions 4.5 Solving Exponential and Logarithmic Equations 4.6 Applications and Models: Growth and Decay 5.1 Systems of Equations in Two Variables 5.2 System of Equations in Three Variables 5.3 Matrices and Systems of Equations 5.4 Matrix Operations 5.5 Inverses of Matrices 5.6 System of Inequalities and Linear Programming 5.7 Partial Fractions 6.1 The Parabola 6.2 The Circle and Ellipse 6.3 The Hyperbola 6.4 Nonlinear Systems of Equations
