• cannot boot Ubuntu after fresh install

  - by Jonathan

  I just installed Ubuntu on a Lenovo v570, and cannot boot into the system. All I get is a loop, where some (bios) info is displayed, and then the computer asks me where I would like to boot from. I tried reinstalling, reinstalling with a custom partition scheme, and boot -repair after the install. None of these work. I can see the files on my harddisk have been copied. I have installed many Ubuntus in the past, as well other distros where custom partitioning is required. I don't know where to find any useful information since I don't even get too the grub menu. One odd thing I noticed. The bios now had options to boot USB, OpenSuse,Fedora, or the HD. I am not dual booting. I also realized that the boot info is for a network boot, which means the computer is not recognizing what to boot. It is boot an HD problem, because I can install other OSs just fine. I am completely stumped. I would like to settle this, and end up with a tutorial, that explains to me what happened.

• Old Lock Retrofitted for Wireless and Key-free Entry

  - by Jason Fitzpatrick

  What do you do if the old key your landlord gave you is poor fit for your apartment’s lock? If you’re the geeky sort, you build a wireless unlocking module to do the work for you. Instructables user Rybitski writes: The key to my apartment never worked quite right because it is a copy of a copy of a copy. I am fairly certain that the dead bolt is original to the building and the property manager seems to have lost the original key years ago. As a result unlocking the door was always a pain. Changing the lock wasn’t an option, but eliminating the need to use a key was. To that end, he built the device seen in the video above. An Arduino Uno drives a servo which in turn opens the deadbolt. The whole thing is controlled by a simple wireless key fob. Hit up the link below for the full build guide including code.

• Subdomain only accessible from one computer

  - by Edan Maor

  I recently added a wildcard A record to my domain (*.root.com), mapping it to a certain elastic ip on AWS. I've configured apache to redirect all references to something.root.com to root.com, except for one specific "dev" subdomain, which is hosting its own site (a Django app, specifically). The Problem: This setup works perfectly for me on my computer. But on other computers around the office, it doesn't seem to work. Specifically, trying to visit dev.root.com gives an "unable to find server" error. Pinging dev.root.com gives a "cannot resolve hostname" error. The weird thing: pinging any other subdomain of root.com does work, from all machines. I would think this was all due to DNS propagation, except all the computers are behind the same office router, so how could that be the case? Any ideas?

• mac osx software always order files alphabetically rather than by type.

  - by george

  i have noticed many mac applications sort the files alphabetically rather than by type. a good example would be coda by panic.com the files in the file menu are organized alphabetically, i requested for them to add the feature to organize files by type and they've said that its a finder thing. so i went in search to look at other applications to see if they were organizing by type i noticed dreamweaver cs4 had this same problem and now including dreamweaver cs5. there has to be something in the mac that does this and that i can modify. i played with spotlight and it now displays its files by type (thinking thats what i can do) but it didnt take affect in other applications. what library are these applications using to display a file menu for its files?

• Is there a way to explore my WHS files via Xbox 360's Media Center app?

  - by bangoker

  I know its a "Console" question but its really more of a Media Center Extender question! I can access the data through the Video/Pictures options, but not through the Media Center App. Also I can only see the videos that are directly on the Videos folder on my WHS, but not any of the subfolders. Same thing in my Laptop, if I connect to my WHS through Media Player it will only show the videos on Videos but not any other sub-folder, but if I open Media Center I can then connect to server and see all the folders.

• How do I start Chrome using a specified "user profile"?

  - by Danny Tuppeny

  I use the new built-in "Users" feature of Chrome to switch between Home/Work accounts easily. However, Chrome remembers the "last" user profile you had selected when launching new windows. This is a problem if I close down my "Home" profile last, because when I then click the Email shortcut on my taskbar, because it goes to mail.mycompany.com using my Home profile, and I'm not logged in. I'd like to change the shortcut to the company webmail to pass a switch that tells Chrome to always start as the "Default" user, regardless of the last one used. Note: I have tried user-data-dir, and this seems to do something very different, completely isolated from the Users functionality built in to Chrome. It's possible I'm using it wrong, but please test this before assuming it does the same thing and posting an answer ;-)

• In Outlook 2013, the reading pane does not display images correctly for most emails (but does for some)

  - by smoldyr

  I am running Microsoft Office Outlook 2013 on Windows 7 Enterprise. When I click on an email in the list of messages, the preview of the message in the reading pane usually will not show the images contained in the email, but instead will show a red 'X'. Sometimes this red 'X' is followed by the text "The linked image cannot be displayed. The file may have been moved, renmaed, or deleted. Verify that the link points to the correct file and location." I am using an IMAP email account. The really strange thing is that for some emails, the images will display, although they take a long time to load. How can I make the images show up in the reading pane?

• Is using a dedicated thread just for sending gpu commands a good idea?

  - by tigrou

  The most basic game loop is like this : while(1) { update(); draw(); swapbuffers(); } This is very simple but have a problem : some drawing commands can be blocking and cpu will wait while he could do other things (like processing next update() call). Another possible solution i have in mind would be to use two threads : one for updating and preparing commands to be sent to gpu, and one for sending these commands to the gpu : //first thread while(1) { update(); render(); // use gamestate to generate all needed triangles and commands for gpu // put them in a buffer, no command is send to gpu // two buffers will be used, see below pulse(); //signal the other thread data is ready } //second thread while(1) { wait(); // wait for second thread for data to come send_data_togpu(); // send prepared commands from buffer to graphic card swapbuffers(); } also : two buffers would be used, so one buffer could be filled with gpu commands while the other would be processed by gpu. Do you thing such a solution would be effective ? What would be advantages and disadvantages of such a solution (especially against a simpler solution (eg : single threaded with triple buffering enabled) ?

• Debugger for file I/O development?

  - by datenwolf

  Okay, the question title may be a bit cryptic. But it aptly describes what I'm looking for: I think every experienced coder went through this numerous times: You get a binary file format specification, you implement the reader for it, and… nothing works like expected. So you run your code in the debugger, go execute through the code line by line, every header field is read in seemingly correct, but when it comes to the bulk data, offset and indices no longer match up. What would really help in this situation was a binary file viewer, that shows you the progress of your file pointer, as you step through the code, and ideally would also highlight all memory maps. Then you could see the context of the current I/O operations, most notably those darn "off-by-one" mistakes, which are even more annoying when reading a file. Implementing such a debugger should not be too hard. traces on the process' file descriptors/handles and triggers on the I/O functions, to update the display. Only: I don't know of such a kind of debugger to exist. Do I just lack knowledge about the existance of such a tool, or is there really no such thing?

• Writing Java in Java

  - by Skeith

  I have been using Java for several months at work now and am becoming mildly competent in it. The problem I think I am having is that I program C++ in Java . By that I mean I have always used C++ and am treating Java as a simple syntax change instead of appreciate if for its own language. For instance a static variable in C++ is the same as a normal variable in Java as Java is all classes so they maintain there values between function calls. Little things like this are tripping me up constantly as I am self taught. What I want is to invest the time to become a good java programmer not just a C++ programmer that can write in Java. The problem is I do not know how to do this. I have tried reading the Java doc pages but I find them very clinical and hard to understand. So what I am looking for is recommendations on how I can learn to think in Java. Books that teach Java concepts not Java syntax, online tutorials that I can work through that give it a context, established Java traditions/best practices and any other thing that you could recommend.

• Mobile Web Framework that will only control rendering and page transitions

  - by rlemon

  I have been using jQueryMobile for a bit now, and there are some things I like about it and others I do not. First I will give a bit of background. I have a light weight mobile application that has a few configurations and 6 pages. Ideally I Would like to load all pages into the DOM (they interact with each other quite often and pages will be switched in the same frequency). The application will post for some JSON every n seconds and refresh the values on the page (yes it is primarily a information display app). with the jQuery Mobile framework the only real thing I like is how easy it is to have a standardized UI a crossed all devices and browsers, I'm really not using too much else out of the framework other than the basic page navigation (if you are familiar with the framework; a bare-bone multi-page design is all i need). Why I want to step away from jQueryMobile is how weighty it is. Not only do you need to include the mobile library, but also the base jQuery libraries. This I do not like because I'm not using jQuery anywhere else on the site. Any suggestions on light-weight mobile frameworks that have a similar rendering as jQueryMobile?

• Certain drives in RAID 5 set intermittently are not recognized

  - by hydroparadise

  I have a curious problem in that 1 (sometimes 2) drives do not get recognized in a RAID 5 set. The server is getting rather old at 5 to 6 years, but still seems to function well once the machine sees all drives. So that leaves me with three areas to consider: the motherboard, the SATA RAID card, or the individual hard drives themselves. I am leaning toward the RAID card, but have not had much dealings with RAID cards. What would cause individual drives not to be recognized in the set? If it was the card, I would think that it would be all or nothing. If it were a single drive, is it possible that it would only work sometimes? The only other thing to consider is that that they are different drives (Seagate and Western Digital) but all around 80 GB. SATA RAID controller is 3ware Escalade 8506-4LP Motherboard is a SuperMicro P4SPA+ Am open and available for more details if needed...

• Shrink system volume, create new partition, & enlarge current partitions w/o losing data?

  - by studiohack

  My machine has a 300 GB hard drive. I'm planning to reinstall Windows 7 on this machine soon. It has three partitions: a System partition, and two equal data partitions for particular types of data (music, photos, docs, etc). These data partitions are too small for the data they hold, and the system partition is large enough to be shrunk. I want to create four partitions in preparation for the fresh reinstall, a System partition, and three data partitions of varying sizes (40, 50, & 60 GB respectively). My question: Can I shrink the System volume, create another partition, and make the existing two data partitions bigger without losing any data that is currently on the hard drive? Or is it better to format the whole thing, and create partitions after (thus removing the current OS) with a partitioning tool booting from CD? Can I reformat and create partitions with the Windows 7 set up DVD?

• Cannot access folder locally, but can remotely

  - by Cylindric

  I'm having a peculiar problem on one of my servers at the moment, which seems to be related to authentication in some way, but I have no idea how to find the root of the problem. I have a folder on the server D:\Somefolder\Logs. If I am connected to the server via an RDP terminal, so essentially "local", I cannot access that folder - I get an access denied. If I am connecting from my machine to it using the share \server\d$\Somefolder\Logs, I can access it. I'm logging in to both machines as the same user. Permissions on the folder seem quite simple, CREATOR OWNER, SYSTEM and Administrators. I am a Domain Admin, and they are in the local "Administrators" group. It is also affecting things like access to SQL Server, so I don't think it's a simple folder-permissions thing. For example, I cannot connect SQL Management Studio to all the local SQL instances using a domain account, but I can if I connect remotely to it.

• Enable Ctrl (or Alt) + arrow keys to mimic 'home' and 'end' functionality

  - by YuKagi

  I am a long time Mac user and I'm now using a Ubuntu machine for development, and while I'm more or less used to a lot of the keyboard shortcuts, one thing I can't get used to is using the 'Home' and 'End' keys to move around lines of text. On a Mac you use "Command + right arrow" to go to the end of a line and "Command + left arrow" to go to the beginning. Is there a way to enable this kind of functionality in Linux? I'm not sure if this would be considered remapping, keyboard shortcuts, or what...

• What are some techniques I can use to refactor Object Oriented code into Functional code?

  - by tieTYT

  I've spent about 20-40 hours developing part of a game using JavaScript and HTML5 canvas. When I started I had no idea what I was doing. So it started as a proof of concept and is coming along nicely now, but it has no automated tests. The game is starting to become complex enough that it could benefit from some automated testing, but it seems tough to do because the code depends on mutating global state. I'd like to refactor the whole thing using Underscore.js, a functional programming library for JavaScript. Part of me thinks I should just start from scratch using a Functional Programming style and testing. But, I think refactoring the imperative code into declarative code might be a better learning experience and a safer way to get to my current state of functionality. Problem is, I know what I want my code to look like in the end, but I don't know how to turn my current code into it. I'm hoping some people here could give me some tips a la the Refactoring book and Working Effectively With Legacy Code. For example, as a first step I'm thinking about "banning" global state. Take every function that uses a global variable and pass it in as a parameter instead. Next step may be to "ban" mutation, and to always return a new object. Any advice would be appreciated. I've never taken OO code and refactored it into Functional code before.

• Updating the jump in game

  - by Luka Tiger

  I am making a Java game and I want my game to run the same on any FPS so I'm using time delta between each update. This is the update method of the Player: public void update(long timeDelta) { //speed is the movement speed of a player on X axis //timeDelta is expressed in nano seconds so I'm dividing it with 1000000000 to express it in seconds if (Input.keyDown(37)) this.velocityX -= speed * (timeDelta / 1000000000.0); if (Input.keyDown(39)) this.velocityX += speed * (timeDelta / 1000000000.0); if(Input.keyPressed(38)) { this.velocityY -= 6; } velocityY += g * (timeDelta/1000000000.0); //applying gravity move(velocityX, velocityY); /*this is method which moves a player according to velocityX and velocityY, and checking the collision */ this.velocityX = 0.0; } The strange thing is that when I have unlimited FPS (and update number) my player is jumping about 10 blocks. It jumps even higher when the FPS is increasing. If I limit FPS it is jumping 4 blocks. (BLOCK: 32x32) I have just realized that the problem is this: if(Input.keyPressed(38)) { this.velocityY -= 6; } I add -6 to velocityY which increases player's Y proportionally to the update number and not to the time. But I don't know how to fix this.

• Unresponsive virtual OS

  - by confusedGeek

  Hopefully someone has a suggestion on how to resolve this. Configuration Host: Win 2003R2 w/Virtual Server 2005R2 Virtual1: Win 2003R2 w/Sql Server 2005 Virtual2: Win 2003R2 w/WSS 3.0 Situation This past weekend the power went out and took down the servers (no UPS, it's a desktop standing in as dev testing server). Since the servers went down the Virtual2 server after running WSS fairly heavily for an hour to two will become unresponsive via HTTP. If I login via virtual server's remote control I don't get anything beyond a background screen. The CPU counter on the virtual server's master status shows that it isn't doing anything. The only thing I have been able to do is to turn off Virtual2, which loses any state changes. Shutdown commands issue from the virtual server master status are ignored. After restarting Virtual2 the event logs and application logs don't indicate what caused the problem. Anyone have an idea as to how to repair the OS, or maybe what could be the problem? Thanks ahead of time.

• What is the value of workflow tools?

  - by user16549

  I'm new to Workflow developement, and I don't think I'm really getting the "big picture". Or perhaps to put it differently, these tools don't currently "click" in my head. So it seems that companies like to create business drawings to describe processes, and at some point someone decided that they could use a state machine like program to actually control processes from a line and boxes like diagram. Ten years later, these tools are huge, extremely complicated (my company is currently playing around with WebSphere, and I've attended some of the training, its a monster, even the so called "minimalist" versions of these workflow tools like Activiti are huge and complicated although not nearly as complicated as the beast that is WebSphere afaict). What is the great benefit in doing it this way? I can kind of understand the simple lines and boxes diagrams being useful, but these things, as far as I can tell, are visual programming languages at this point, complete with conditionals and loops. Programmers here appear to be doing a significant amount of work in the lines and boxes layer, which to me just looks like a really crappy, really basic visual programming language. If you're going to go that far, why not just use some sort of scripting language? Have people thrown the baby out with the bathwater on this? Has the lines and boxes thing been taken to an absurd level, or am I just not understanding the value in all this? I'd really like to see arguments in defense of this by people that have worked with this technology and understand why its useful. I don't see the value in it, but I recognize that I'm new to this as well and may not quite get it yet.

• How should I create a mutable, varied jtree with arbitrary/generic category nodes?

  - by Pureferret

  Please note: I don't want coding help here, I'm on Programmers for a reason. I want to improve my program planning/writing skills not (just) my understanding of Java. I'm trying to figure out how to make a tree which has an arbitrary category system, based on the skills listed for this LARP game here. My previous attempt had a bool for whether a skill was also a category. Trying to code around that was messy. Drawing out my tree I noticed that only my 'leaves' were skills and I'd labeled the others as categories. Explanation of tree: The Tree is 'born' with a set of hard coded highest level categories (Weapons, Physical and Mental, Medical etc.). Fro mthis the user needs to be able to add a skill. Ultimately they want to add 'One-handed Sword Specialisation' for instance. To do so you'd ideally click 'add' with Weapons selected and then select One-handed from a combobox, then click add again and enter a name in a text field. Then click add again to add a 'level' or 'tier' first proficiency, then specialisation. Of course if you want to buy a different skill it's completely different, which is what I'm having trouble getting my head around let alone programming in. What is a good system for describing this sort of tree in code? All the other JTree examples I've seen have some predictable pattern, and I don't want to have to code this all in 'literals'. Should I be using abstract classes? Interfaces? How can I make this sort of cluster of objects extensible when I add in other skills not listed above that behave differently? If there is not a good system to use, if there a good process for working out how to do this sort of thing?

• Engine for 2D Top-Down Physics-Based Skeletal Animation

  - by RylandAlmanza

  I just watched at the Sui Generis video, and was completely amazed. Specifically, the part where the big troll thing is beating up the player with his flail. This got me really excited, and I would like to try implementing something like this in a 2D Top-Down format. Something like this. That atloria example seems simple enough, but it's not exactly what I'm looking to make. I think atloria is using predefined animations, where as I would like to make something more physics-based like the Sui Generis engine does. So, I'm wondering what physics engines might work for something like this, and if I'd need to implement my own skeletal system, or if I could just use "joints" and such from the engine. The only experience I have in terms of physics engines is Box2D, which I've heard shouldn't be used for top-down settings, and I can think of a few reasons it wouldn't work out well. One of those reasons being gravity. In box 2D, gravity pulls towards a side of the screen (usually the bottom.) I wouldn't want my player's forearms constantly being pulled to one side. :) Also should mention that the programming language doesn't matter all that much to me. I'm currently playing with HTML5 stuff, though. :) Thanks in advance!

• How to make the jump from consumer support to enterprise support?

  - by Zac Cramer

  I am currently a high level consumer break/fix technician responsible for about 300-400 repairs a month. I am good at my job, but bored, and I want to move into the enterprise side of my company, dealing with Server 2008 R2 and exchange and switches and routers that cost more than I make in a month. How do I make this transition? Whats the best thing to learn first? Is there a standard trajectory for making this leap from consumer to business? I am full time employed, so going back to school is not a great option, but I have no life, so spending my nights and weekends reading and practicing is totally within my realm. I am basically overwhelmed by the number of things to learn, and looking for any advice you may have on the best way to proceed. PS - I apologize if this is a not quite the right forum for this, I know its not a technical question exactly, but I also know the sorts of people I want to answer this question are reading this website.

• Dynamic Jump spot

  - by Pasquale Sada

  I have an initial velocity V(Vx,Vy,VZ) and a spot where he stands still at S(Sx,Sy,Sz). What I'm trying to achieve is a jump on a spot E(Ex,Ey,Ez) where you have clicked on(only lower or higher spot, because I've in place a simple steering behavior for even terrains). There are no obstacle around. I've implemented a formula that can make him jump in a precise way on a spot but you need to declare an angle: the problem arise when the selected spot is straight above your head. It' pretty lame that the char hang there and can reach a thing that is 1cm above is head. I'll share the code I'm using: Vector3 dir = target - transform.position; // get target direction float h = dir.y; // get height difference dir.y = 0; // retain only the horizontal direction float dist = dir.magnitude ; // get horizontal distance float a = angle * Mathf.Deg2Rad; // convert angle to radians dir.y = dist * Mathf.Tan(a); // set dir to the elevation angle dist += h / Mathf.Tan(a); // correct for small height differences // calculate the velocity magnitude float vel = Mathf.Sqrt(dist * Physics.gravity.magnitude / Mathf.Sin(2 *a)); return vel * dir.normalized;

• How do I fix a terrible system error on ubuntu 12.04

  - by Anonymous

  I don't know what happened, but one day my computer had some sort of a system error and could no longer update itself. The software center will not open, it will begin to initialize and then a message pops up saying theres a system error and needs to shut down the software center. Then another box pops up after I go to report it saying it was unable to identify source or package name. I also can't extract a zipped folder to anything, or reinstall Ubuntu from a USB boot drive anymore, it keeps telling me my my computer isn't compatible when I know for a fact it is, because thats how I got Ubuntu on here in the first place. the only thing I know about this error is that a message popped up after I went to check for updates saying to report the problem and include this message in the report: 'E:malformed line 56 in source list /etc/apt/sources.list (dist parse)' it also called it a bug. I just want to know how to either get rid of the bug completely or find some way to be able to reinstall Ubuntu again. I know it's not a lot of information, but It's all I can give. Sorry.

• Rack processes taking over CPU under Passenger

  - by pjmorse

  I have a Spree site running the following stack: Nginx 1.0.8 Passenger 3.0.9 Ruby 1.9.2-p290 Rack 1.3.6 Rails 3.1.4 Spree 0.70.5 I recently upgraded from Spree 0.70.3, which also brought a Deface upgrade from 0.7.x to 0.8.0. Since then things have been very unstable. Recently we've seen some CPU-hogging processes which drive load up on the server and grind the whole thing to a stop. They're Rack processes and it looks like Passenger is starting them; they're owned by the site-runner user, an unprivileged user who owns the application code. (Passenger automatically runs the site code as the user who owns it.) If I restart Nginx and kill the runaway processes, it helps for a while, but eventually similar processes return and bog things down again. How can I figure out what's starting these processes, what they're trying to do, and how to stop them?
