• How do I encrypt but share a number of folders?

  - by d3vid

  I want to achieve the following functionality. Is it possible? Boot up computer (possibly via WakeOnLan or WakeOnPlan). Either be automatically logged in, or log in via login screen, or log in remotely. I change this behavior occasionally, so full disk encryption wouldn't work for me because it requires a password on bootup (which would it would prevent the remote bootup options, and the automatic login option). I am only interested in encrypting data, not the entire harddrive. Once logged in either: a launcher/tray icon is available to launch encryption app (preferred) run encryption app from the dash Prompted to unlock encrypted folder(s) individually. Unlocked folders are available to: me, apps I am running (e.g. editors, SpiderOak) Ideally, folders that I share with bindfs can be locked/unlocked by other users too. A key point is that once I have unlocked an encrypted folder, I don't want to have to think about it again. I currently achieve this via TrueCrypt (except for the last part). Unfortunately TrueCrypt isn't well integrated with Ubuntu (licensing issues prevent Debian from including it in their repo, the interface isn't quite integrated with Unity, setting it as a startup app doesn't quite work, sharing encrypted folders isn't really part of its design). Is there an alternative to TrueCrypt that is better integrated with the Ubuntu GUI and would suit this workflow?

• HP Envy 14, Ubuntu 10.10 and trouble with the graphics cards

  - by Carsten Gehling

  A few days ago I bought a HP Envy 14, containing 2 graphics card: An integrated Intel graphics card, and an ATI HD 5650. I've installed Ubuntu 10.10 32-bit on the machine. Most things work fine out of the box, but the graphics cards are giving me trouble. When booting, I get the message "failed to get i915 symbols, graphics turbo disabled". Then the screen blanks out during the remaining boot period. I am able to get the display working by changing to one of the consoles, then closing and opening the laptop's lid. It seems that Ubuntu gets confused about which card to use. I've read here: http://www.andreas-demmer.de/en/2010/07/18/testbericht-linux-auf-dem-hp-envy-14 that I should be able to turn off one the cards by echoing keywords into /sys/kernel/debug/vgaswitcheroo/switch, but that path is not available on my system. The BIOS does not have any methods to switch of the ATI card. Help anyone? /Carsten

• Why is autologon in Windows 7 a security risk

  - by Phenom

  If I set my Windows 7 account to automatically logon so I don't have to type a password, and I don't have to click my username on the logon screen, I heard it's a security risk. From Windows 7 Auto Login: Although I don’t personally recommend this, there are some people out there who don’t want to bother with using a password to protect their Windows user account. Of course, using a password in Windows isn’t required, only suggested. But even if you don’t fill one in, you still have to click your user icon to start the login process. An easier way - although again much less secure - is to enable auto-logins for your Windows PC. This is possible in Windows 7, as it was in prior versions, but it takes a little finagling to do so. (And for good reason, darn it.) What is risky about it besides people being able to logon locally? Does it make it easier for hackers to logon remoately?

• Libgdx actor bounds are wrong

  - by Undume

  The Actor's boundaries are not centered at the ButtonText but I used the setBounds() method. The higher the Y position is, the less centered is the boundary. The weird thing is that i only created and added to the Stage one button but the screen shows two. When i click the top button, the bottom one is the one highlighted. How can i fix that? import com.badlogic.gdx.Game; import com.badlogic.gdx.Gdx; import com.badlogic.gdx.files.FileHandle; import com.badlogic.gdx.scenes.scene2d.Stage; import com.badlogic.gdx.scenes.scene2d.ui.Skin; import com.badlogic.gdx.scenes.scene2d.ui.TextButton; public class MyGame extends Game { Stage stage; @Override public void create() { stage=new Stage(); FileHandle skinFile = new FileHandle("data/resources/uiskin/uiskin.json"); Skin skin = new Skin(skinFile); TextButton sas=new TextButton("dd",skin); sas.setBounds(0, 500, 100, 100); stage.addActor(sas); Gdx.input.setInputProcessor(stage); } @Override public void dispose() { super.dispose(); } @Override public void render() { super.render(); stage.act(Gdx.graphics.getDeltaTime()); stage.draw(); } @Override public void resize(int width, int height) { super.resize(width, height); } @Override public void pause() { super.pause(); } @Override public void resume() { super.resume(); } }

• My boss has a different idea of a website's UX [migrated]

  - by NicoJuicy

  Let me explain the situation. I started transforming a "old (.Net 2.0)" Application into a webapplication. Problem here is, that no-one here is really acquainted with the UX of a website (Simple, efficient). Eventhough, i still have to regard that the website can be tailored to a customer needs through parameters (yeah, i know :s ) For example: I wanted to have a layout similar to invoicemachine (= as simple as possible). -- He wants a Ribbon toolbar. Going to a supplier gives the list of supplier -- He wants to display the "Create Supplier" screen where you can use the wildcards in a certain textbox, to search for a specific Supplier and then give the list of the suppliers. Also, i need 4 search/filter mechanisms: people can search per field with wildmarks can filter the suppliers search a keyword through all the data of a supplier filter the "list Suppliers" page by the first letter of the name. LIST Suppliers | A | D | Z Adam Wrincle ADD |EDIT |Delete Damzel InDistress ADD |EDIT |Delete Zorro ADD |EDIT |Delete I can't seem to get through to him, that the UX of a website needs to be differently than a Windows Application. If he wants to bring all the logic of the windows app into a website, why letting me build a website then? Stick to the old solution. Am i mistaking so hard or how could i convince / show him that an online-solution is something different than the offline solution. He already "saw" online solutions of other applications to get an idea, but if i suggest something he won't listen (if it's GUI / UX related, that is).

• Struggling to get set up with JOGL2.0

  - by thecoshman

  I guess that Game Dev' is a more sensible place for my problem then SO. I did have JOGL1.1 set up and working, but I soon discovered that it did not support the latest OpenGL, so I started work on upgrading to JOGL2.0 it's not gone too well. Firstly, is it worth me trying to get JOGL to work, or should I just move over to LWJGL? I am fairly comfortable with OpenGL (via C++) and from what I did get working with JOGL1.1, I seem to be OK adapting to it. Assuming that I stick with JOGL, am I foolish for trying to use JOGL2.0? From what I can gather, JOGL2.0 is still in beta, but I am willing to go with it as I want to make use of the latest OpenGL I can. I have been using the Eclipse IDE and have set up a user library for JOGL, here is a screen shot of the configuration and I have added this user library to my own Eclipse project. the system variable %JOGL_HOME% points to "C:\Users\edacosh\Downloads\JOGL2.0" so that should work fine. Now, the problem I actually having, when I try to run my code, on the line GLProfile glp = GLProfile.getDefault(); The code stops with the following message... Exception in thread "main" java.lang.NoClassDefFoundError: com/jogamp/common/jvm/JVMUtil at javax.media.opengl.GLProfile.<clinit>(GLProfile.java:1145) at DiCE.DiCE.<init>(DiCE.java:33) at App.<init>(App.java:17) at App.main(App.java:12) Caused by: java.lang.ClassNotFoundException: com.jogamp.common.jvm.JVMUtil at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 4 more I have also set my project to ensure that it is using jre6 along with jdk6, as I was having some issues. I hope I have given you enough information to be able to help me. It probably doesn't help that I am rather new to Java, been developing in C++ for ages. Thanks

• How do I properly use String literals for loading content?

  - by Dave Voyles

  I've been using verbatim string literals for some time now, and never quite thought about using a regular string literal until I started to come across them in Microsoft provided XNA samples. With that said, I'm trying to implement a new AudioManager class from the Net Rumble sample. I have two (2) issues here: Question 1: In my code for my GameplayScreen screen I have a folder location written as the following, and it works fine: menuButton = content.Load<SoundEffect>(@"sfx/menuButton"); menuClose = content.Load<SoundEffect>(@"sfx/menuClose"); If you notice, you'll see that I'm using a verbatim string, with a forward slash "/". In the AudioManager class, they use a regular string literal, but with two backslashes "\". I understand that one is used as an escape, but why are they BACK instead of FORWARD? (See below) soundList[soundName] = game.Content.Load<SoundEffect>("audio\\wav\\"+ soundName); Question 2: I seem to be doing everything correctly in my AudioManager class, but I'm not sure of what this line means: audioFileList = audioFolder.GetFiles("*.xnb"); I suppose that the *xnb means look for everything BUT files that end in *xnb? I can't figure out what I'm doing wrong with my file locations, as the sound effects are not playing. My code is not much different from what I've linked to above. private AudioManager(Game game, DirectoryInfo audioDirectory) : base(game) { try { audioFolder = audioDirectory; audioFileList = audioFolder.GetFiles("*.mp3"); soundList = new Dictionary<string, SoundEffect>(); for (int i = 0; i < audioFileList.Length; i++) { string soundName = Path.GetFileNameWithoutExtension(audioFileList[i].Name); soundList[soundName] = game.Content.Load<SoundEffect>(@"sfx\" + soundName); soundList[soundName].Name = soundName; } // Plays this track while the GameplayScreen is active soundtrack = game.Content.Load<Song>("boomer"); } catch (NoAudioHardwareException) { // silently fall back to silence } }

• Can web apps allow fast data-typists to "type-ahead"?

  - by user61852

  In some data entry contexts, I've seen data typists, type really fast and know so well the app they use, and have a mechanic quality in their work so that they can "type ahead", ie continue typing and "tab-bing" and "enter-ing" faster than the display updates, so that in many occasions they are typing in the data for the next form before it draws itself. Then when this next entry form appears, their keystrokes fill the text boxes and they continue typing, selecting etc. In contexts like this, this speed is desirable, since this persons are really productive. I think this "type ahead of time" is only possible in desktop apps, but I may be wrong. My question is whether this way of handling the keyboard buffer (which in desktop apps require no extra programming) is achievable in web apps, or is this impossible because of the way web apps work, handle sessions, etc (network latency and the overhead of generating new web pages ) ? Edit: By "type ahead" I mean "keyboard type ahead" (typing faster than the next entry form can load), not suggets-as-you-type-like-google type ahead. Typeahead is a feature of computers and software (and some typewriters) that enables users to continue typing regardless of program or computer operation—the user may type in whatever speed he or she desires, and if the receiving software is busy at the time it will be called to handle this later. Often this means that keystrokes entered will not be displayed on the screen immediately. This programming technique for handling user what is known as a keyboard buffer.

• Metacity toggle fullscreen not working under Lucid; worked with Karmic.

  - by Andy

  Hi all, I'm working on a 11" screen, so I frequently want to use applications in fullscreen. I'm no expert on GNOME, but I remember doing a search a while back, and finding out about metacity, and how to use that to allow any window to be put in fullscreen. This worked great on Karmic, but it doesn't seem to be working under Lucid. Here's what I do. Run gconf-editor. Go to /apps/metacity/window_keybindings. Change toggle_fullscreen from disabled to <Control><Shift>F. Unfortunately it doesn't work. I know that I've got the right syntax because I can see other shortcuts and use them as a template. I have no idea what's wrong, and no idea how to move forwards/debug. Any suggestions much appreciated. TIA Andy

• PGP Desktop Whole disk Encryption paused on a toshiba ultrabook z935

  - by garg

  I have a Toshiba z930 Ultrabook with PGP Desktop installed for whole disk encryption. It installed correctly, and started encrypting but it stays paused. If I reboot, it shows me the PGP desktop username, password, domain screen. If I enter in my credentials, it allows me to get into windows but encryption remains paused. If I click on resume, it lets me enter a password, accepts it but then it doesn't do anything. One suspicious thing is that in the 'Select disk or partition to encrypt' box, it says, C: 120B fixed disk. Unknown Bus: TOSHIBA THNSNS12... Do I need to change something in the BIOS, or install any drivers so that it doesn't see it as an Unknown Bus?

• Drawing multiple triangles at once isn't working

  - by Deukalion

  I'm trying to draw multiple triangles at once to make up a "shape". I have a class that has an array of VertexPositionColor, an array of Indexes (rendered by this Triangulation class): http://www.xnawiki.com/index.php/Polygon_Triangulation So, my "shape" has multiple points of VertexPositionColor but I can't render each triangle in the shape to "fill" the shape. It only draws the first triangle. struct ShapeColor { // Properties (not all properties) VertexPositionColor[] Points; int[] Indexes; } First method that I've tried, this should work since I iterate through the index array that always are of "3s", so they always contain at least one triangle. //render = ShapeColor for (int i = 0; i < render.Indexes.Length; i += 3) { device.DrawUserIndexedPrimitives<VertexPositionColor> ( PrimitiveType.TriangleList, new VertexPositionColor[] { render.Points[render.Indexes[i]], render.Points[render.Indexes[i+1]], render.Points[render.Indexes[i+2]] }, 0, 3, new int[] { 0, 1, 2 }, 0, 1 ); } or the method that should work: device.DrawUserIndexedPrimitives<VertexPositionColor> ( PrimitiveType.TriangleList, render.Points, 0, render.Points.Length, render.Indexes, 0, render.Indexes.Length / 3, VertexPositionColor.VertexDeclaration ); No matter what method I use this is the "typical" result from my Editor (in Windows Forms with XNA) It should show a filled shape, because the indexes are right (I've checked a dozen of times) I simply click the screen (gets the world coordinates, adds a point from a color, when there are 3 points or more it should start filling out the shape, it only draws the lines (different method) and only 1 triangle). The Grid isn't rendered with "this" shape. Any ideas?

• My Mac is slow but don't know what's slowing it down

  - by duality_

  My Mac (Macbook Pro) is sometimes slow doing basic tasks, like browsing the web or something like that. If I open Activity Monitor, I have (maybe) one program that is about 10 % CPU, others are below 1 %. My CPU usage is not full. I still have more than 2 GB of free memory (out of 5 GB). There is no heavy I/O activity like copying files. My open programs are Google Chrome (6 tabs, none of which are in some way (flash, many DOM objects, Javascript) have IMO, except maybe Gmail), Activity Monitor, Finder, Sublime Text 2 (text editor) and iTerm (terminal). What is causing the slowdown? "Slow" being: taking time to write these characters (I press the keyboard keys but there is a delay before I see them on the screen), changing tabs or programs, etc.

• Suspended Laptop Cannot Wake Up - Ubuntu

  - by Zack

  I've got an ASUS G73JH, and whenever I suspend it or hibernate it, it will not wake up. The screen stays backlight but is black. I can't: Awaken it with the keyboard Awaken it with the mouse Soft power-off by pressing the power button I have to hold down the power button and shut it down that way, and this seems a little unreasonable. Is there a place I could look for more detail as to what's causing this? Is there a known quick-fix to this issue?

• Render on other render targets starting from one already rendered on

  - by JTulip

  I have to perform a double pass convolution on a texture that is actually the color attachment of another render target, and store it in the color attachment of ANOTHER render target. This must be done multiple time, but using the same texture as starting point What I do now is (a bit abstracted, but what I have abstract is guaranteed to work singularly) renderOnRT(firstTarget); // This is working. for each other RT currRT{ glBindFramebuffer(GL_FRAMEBUFFER, currRT.frameBufferID); programX.use(); glActiveTexture(GL_TEXTURE0); glBindTexture(GL_TEXTURE_2D, firstTarget.colorAttachmentID); programX.setUniform1i("colourTexture",0); glActiveTexture(GL_TEXTURE1); glBindTexture(GL_TEXTURE_2D, firstTarget.depthAttachmentID); programX.setUniform1i("depthTexture",1); glBindBuffer(GL_ARRAY_BUFFER, quadBuffID); // quadBuffID is a VBO for a screen aligned quad. It is fine. programX.vertexAttribPointer(POSITION_ATTRIBUTE, 3, GL_FLOAT, GL_FALSE, 0, (void*)0); glDrawArrays(GL_QUADS,0,4); programY.use(); glActiveTexture(GL_TEXTURE0); glBindTexture(GL_TEXTURE_2D, currRT.colorAttachmentID); // The second pass is done on the previous pass programY.setUniform1i("colourTexture",0); glActiveTexture(GL_TEXTURE1); glBindTexture(GL_TEXTURE_2D, currRT.depthAttachmentID); programY.setUniform1i("depthTexture",1); glBindBuffer(GL_ARRAY_BUFFER, quadBuffID); programY.vertexAttribPointer(POSITION_ATTRIBUTE, 3, GL_FLOAT, GL_FALSE, 0, (void*)0); glDrawArrays(GL_QUADS, 0, 4); } The problem is that I end up with black textures and not the wanted result. The GLSL programs program(X,Y) works fine, already tested on single targets. Is there something stupid I am missing? Even an hint is much appreciated, thanks!

• How to Hibernate from .NET Apps and How to enable Hibernate in Windows XP

  The usage of Computer desktop or laptop is increased all around the world phenomenally. This link gives you the picture on how power consumption is for various devices we use daily. to reduce the power consumption Hibernate is one of the best way provided by default in Windows Vista or Windows 7. Hibernate feature enables you to close the machine without closing your applications, that means the applications will be restored as they were once we restart the machine. Hibernate feature is not enabled in Windows XP by default. I’ve seen many people that they run (do not switch off) the machines months and months as they do not want to close the windows or applications running in Windows XP. below are the steps to enable Hibernate in Windows XP. Right click on Desktop. Click on properties. Go to screen save tab. Click on power button Select Hibernate tab Check the checkbox “Enabled Hibernate” Apply the settings. Now when you try to shutdown, “Shut down windows” dialog shows “Hibernate” options. Now you can safely close the machine without closing your applications or windows as they will be restored once you on the machine. </SPAN? Some time you might want to provide this future programmatically for the applications you develop for windows. Generally you might want to provide this option in windows applications where process needs huge time.

• How can I get something like Nautilus's "spatial" behaviour in 11.10 and later?

  - by Dylan McCall

  Until recently, Nautilus had an optional "spatial" mode as an alternative to its usual browser mode. Users could enable it by opening Nautilus's preferences and selecting "Open each folder in its own window." Choosing this option resulted in a stripped down interface, and folders would always open in the same place on the screen. It looked something like this: That checkbox is still there, but it doesn't do the same thing: while every folder opens in a new window, those windows are all the same size and positioned the same way. Nautilus doesn't restore the size and position of each folder, which is what spatial mode was all about. This difference really shows if someone opens a folder in a new window, and then opens the same folder again. Nautilus will create another window instead of focusing the existing window. I help someone who is currently using Ubuntu 10.04, and he will be upgrading to 12.04 in the future. He is very comfortable with Nautilus's spatial behaviour and I think he would be disappointed to lose it. Is there an alternative file manager, or perhaps some less obvious option, that will give him an interface similar to the one he is comfortable with?

• SLI Artifact issues

  - by sloughk

  When I enable SLI I keep getting artifacts in random games and in Windows Aero sometimes . It doesn't seem to be about over-heating as it happens randomly, and sometimes whole computers just crashes (not blue-screen, just black gone...) My setup: Geforce 8800 GTS 320MB ( http://www.bfgtech.com/bfgr88512gtoce.aspx ) x 2 GIGABYTE EX58-UD4 Windows 7 RC PSU 800W I've got the latest NVIDIA drivers and F5 BIOS update (*SLI update*). When I disable SLI and use the cards separately they are working just fine even in games. Any idea why this might happen?

• isometric drawing order with larger than single tile images - drawing order algorithm?

  - by Roger Smith

  I have an isometric map over which I place various images. Most images will fit over a single tile, but some images are slightly larger. For example, I have a bed of size 2x3 tiles. This creates a problem when drawing my objects to the screen as I get some tiles erroneously overlapping other tiles. The two solutions that I know of are either splitting the image into 1x1 tile segments or implementing my own draw order algorithm, for example by assigning each image a number. The image with number 1 is drawn first, then 2, 3 etc. Does anyone have advice on what I should do? It seems to me like splitting an isometric image is very non obvious. How do you decide which parts of the image are 'in' a particular tile? I can't afford to split up all of my images manually either. The draw order algorithm seems like a nicer choice but I am not sure if it's going to be easy to implement. I can't solve, in my head, how to deal with situations whereby you change the index of one image, which causes a knock on effect to many other images. If anyone has an resources/tutorials on this I would be most grateful.

• Is this possible?

  - by PythonNewbie2

  Hello, I'm exploring some technologies and JSP with JSF 2.0 and Primefaces seems really cool. I'm new to all of these, but I'm a fast learner. I wondering if I can create the web app I want withh JSP/JSF/Primefaces or should I be looking to different technologies? If I should, which ones do you recommend? Here's a basic description of the app: Users log in with their username and password (maybe I can somehow incorporate google OPENID)? With a really nice UI, they will be presented a large list of questions specific to a certain category, for example, JSP. When they click on any of these questions, a little input opens up below it to allow the user to put in a link. If the link they enter has the same question on that webpage the URL points to, they will be awarded one point. This question then disappears and gets added to a different page that has a list of all correctly linked questions. On the right side of the screen, there will be a leaderboard with the usernames of the people with the top ten points. Is this possible with JSP/JSF/Primefaces, or should I be looking elsewhere for a different web technology? The idea is relatively simple - to be able to compile links to external websites for specific questions. I know I can build the UI easily with Primefaces. What I'm not sure is if JSP/JSF gives the ability to parse HTML at a certain URL to see if it contains words. I can do this with python easily by using urllib. Any help would be appreciated!!! What would be more helpful than a "Yes" or "No" answer would be links to where I can see sample code of external HTML parsing. Your input is truly appreciated! Thanks!

• Getting rid of Massive View Controller in iOS?

  - by Earl Grey

  I had a discussion with my colleague about the following problem. We have an application where we need filtering functionality. On any main screen within the upper navigation bar, there is a button in the upper right corner. Once you touch that button, an custom written Alert View like view will pop up modally, behind it a semitransparent black overlay view. In that modal view, there is a table view of options, and you can choose one exclusively. Based on your selection, once this modal view is closed, the list of items in the main view is filtered. It is simply a modally presented filter to filter the main table view.This UI design is dictated by the design department, I cannot do anything about it so let accept this as a premise. Also the main filter button in the navbar will change colours to indicate that the filter is active. The question I have is about implementation. I suggested to my colleague that we create a separate XYZFilter class that will be an instance created by the main view controller acquire the filtering options handle saving and restoration of its state - i.e. last filter selected provide its two views - the overlay view and the modal view be the datasource for the table in its modal view. For some unknown reason, my colleague was not impressed by that approach at all. He simply wants to do these functionalities in the main view controller, maybe out of being used to do this in the past like that :-/ Is there any fundamental problem with my approach? I want to keep the view controller small, not to have spaghetti code create a reusable component (for use outside the project) have more object oriented, decoupled approach. prevent duplication of code as we need the filtering in two different places but it looks the same in both.. Any advice?

• Unity's gone! How do I get it back?

  - by Kelley

  Earlier today my Unity desktop disappeared: I got a black screen with white text, but it disappeared too quickly for me to read. When the desktop reappeared, it was the Ubuntu Classic desktop. I used $ unity --reset but that did not do anything. I tried rebooting so I could choose unity from the list when I logged in, but although there was Ubuntu choice, there was no unity listed (but classic was listed). I was able to install Unity 2D and am using that, but really want to get 3D back. I had been using Ubuntu without problems for several weeks when this happened. My graphics card is onboard a Dell Latitude desktop - a couple years old - and is reported as an Intel G33/G31. I've looked at other requests for help here, and tried suggestions when they seemed to relate to similar problems, but nothing seems to work so far. Any ideas? Thanks! This is part of the output of my latest attempt to run unity --reset Window manager warning: 0x3e01c35 () appears to be one of the offending windows with a timestamp of 1309472834. Working around...

• Directly paste clipboard image into gmail message

  - by Frank Meulenaar

  I would like to be able to directly paste my clipboard image into a Gmail message. I could then just do alt-print screen, go to Gmail compose and press ctrl-v to embed a screenshot, for instance. I'm not talking about embedding a image from disk into my email; that's easily done. I want to skip the step where I have to save it to disk first. Eudora/Thunderbird support this. There's a program that does this, it's at picturepaste.com, but it's paid (and and the website uses Javascript for no obvious reasons). You can see the demo movie there if it's not clear what I would like. I would like to find a free alternative, or make one myself, but I have no clue how picturepaste works.
