• View the Time & Date in Chrome When Hiding Your Taskbar

  - by Asian Angel

  Do you prefer keeping your Taskbar hidden but still need to keep watch on what time it is? Now you can keep track of the time without the Taskbar using the Date Today extension for Google Chrome. A Look at Date Today with Different Themes This extension does one thing and does it well…it provides you with an “active icon” clock that will let you view the time and date in two fashions. The first is by hovering your mouse over the “Toolbar Clock Button”… And the second is by clicking on the “Toolbar Clock Button” to view an enlarged version. Here you can see the extension in use with five different themes to get an idea of how it might look with the theme that you are currently using. It does stand out very nicely with brighter or darker colored themes. Conclusion While this extension is obviously not for everyone it will make a nice (and useful) addition to Chrome for those who prefer keeping their Taskbar hidden.

• Ubuntu 12.04 won't shut down - stopping winbind daemon

  - by jan

  My Precise Pangolin sometimes won't shut down - the screen is black with text on it. Mostly last line says something like "stopping winbind deamon" (sometimes also virtualbox, which is above winbind daemon; edit: sometimes the last line says "running unattended updates") and it stays like this for about ten miutes. Then I usually hold the power button for 5s to shut it down. It's very unpredictable - sometimes the computer shuts down without problem and sometimes it hangs. I've tried many ways to shut it down: HW button, panel applet, sudo shutdown -h now, sudo poweroff, sudo halt, etc. even sudo reboot or restart from panel applet have this problem. Sometimes it works ok but every method named hung at least once on the same (damned) line. My specs: FUJITSU SIEMENS LIFEBOOK E8310, Intel Core2 Duo T7300 @ 2.00GHz, 3GB RAM, GPU: Mobile Intel(R) 965 Express Chipset Family Ubuntu 12.04.2 32bit, 3.5.0-41-generic kernel (but it did it on older kernels and 12.04.x systems too). Any ideas what should I try next? Thanks a lot! Jan

• Windows 7/Outlook 2010 cut off controls on form windows

  - by D..

  I am running windows 7 with multiple monitors. 2 at 1920 x 1200 and 1 at 1600x900 resolution. Controls are cut off and I cannot view the entire content of the window. As far as I can tell I only have the issue with Outlook 2010, it may be present in other applications but I haven't noticed it. For example to get to the more settings button I have to use tab and then click enter. The more settings button is never visible. I have used applications that allow you to force windows to be resizable, however the anchoring is such that it remains cut off. This has been present over multiple clean installs on the system. My DPI is set to 100% unlike this issue.

• Converting a WIndows Store App to Android

  - by pm_2

  I cross posted this from SO I'm very new to Xamarin. I have a few published Windows Store apps and want to convert them to Android. I'm attempting to use Xamarin for this. I'm just using the free version of Xamarin. Here's where I am so far: I am trying two apps - one was build with Monogame and one is just build on the WinRT framework. I have managed to get them both into Xamarin studio, basically by hacking the csproj files. I'm getting build errors because it's missing references. There does appear to be some equivalent Mono / .Net4 libraries, but things like Microsoft.Xna.Framework seem to be missing. So, my question is: am I going about this the right way and, if so, am I missing a step ("convert dependencies" or something)? If I'm not going about this the right way then how should I be doing this (I found very few online resources on this subject)?

• Exchange 2010 Deployment Notes &ndash; iPhone and Exchange ActiveSync issue

  - by BWCA

  After we moved one of our user mailboxes from Exchange 2003 to 2010, the user started getting a Cannot get mail. The connection to the server failed error message on their iPhone device. There are a lot of references on Google to check for inherited permissions to resolve the error message.  We quickly determined that we were not dealing with a permissions issue. After some additional troubleshooting and research, we were able to isolate the problem to a device partnership issue. To resolve the issue, use ADSI Edit to find the user object. When you find the user object, double-click on it and you should see a CN=ExchangeActiveSyncDevices container under the user object as shown below.  On the right-hand side, you should see one or more device partnerships.   Right-click the device partnership according to the device the user is using, and click Delete. After you remove the device partnership, please wait until Active Directory replication completes before you set up the device again.

• Movement prediction for non-shooters

  - by ShadowChaser

  I'm working on an isometric (2D) game with moderate-scale multiplayer - 20-30 players. I've had some difficulty getting a good movement prediction implementation in place. Right now, clients are authoritative for their own position. The server performs validation and broad-scale cheat detection, and I fully realize that the system will never be fully robust against cheating. However, the performance and implementation tradeoffs work well for me right now. Given that I'm dealing with sprite graphics, the game has 8 defined directions rather than free movement. Whenever the player changes their direction or speed (walk, run, stop), a "true" 3D velocity is set on the entity and a packet it sent to the server with the new movement state. In addition, every 250ms additional packets are transmitted with the player's current position for state updates on the server as well as for client prediction. After the server validates the packet, it gets automatically distributed to all of the other "nearby" players. Client-side, all entities with non-zero velocity (ie/ moving entities) are tracked and updated by a rudimentary "physics" system - basically nothing more than changing the position by the velocity according to the elapsed time slice (40ms or so). What I'm struggling with is how to implement clean movement prediction. I have the nagging suspicion that I've made a design mistake somewhere. I've been over the Unreal, Half-life, and all other movement prediction/lag compensation articles I could find, but they all seam geared toward shooters: "Don't send each control change, send updates every 120ms, server is authoritative, client predicts, etc". Unfortunately, that style of design won't work well for me - there's no 3D environment so each individual state change is important. 1) Most of the samples I saw tightly couple movement prediction right into the entities themselves. For example, storing the previous state along with the current state. I'd like to avoid that and keep entities with their "current state" only. Is there a better way to handle this? 2) What should happen when the player stops? I can't interpolate to the correct position, since they might need to walk backwards or another strange direction if their position is too far ahead. 3) What should happen when entities collide? If the current player collides with something, the answer is simple - just stop the player from moving. But what happens if two entities take up the same space on the server? What if the local prediction causes a remote entity to collide with the player or another entity - do I stop them as well? If the prediction had the misfortune of sticking them in front of a wall that the player has gone around, the prediction will never be able to compensate and once the error gets to high the entity will snap to the new position.

  I have an issue here with my computer using ubuntu 10.10 on a 64 bits machine. When I start it, I have the login screen, I enter my credentials but instead of starting the session it reloads the login screen again. I checked the disc using fsck and it seems clean. How should I proceed to diagnose and repair this issue? Thanks!

• Data capture from other sheet into Summary sheet

  - by Hemant

  an Excel workbook which has Summary sheet, Pending and Master Sheet. My requirement is below and try to develop a Macro or VB logic for excel • I want to control this workbook from Summary sheet. o Generate Fault Summary – ? I have set logic but if doesn’t give warning if sheet name is exists , so need to add this logic . ? When we press the Fault Report Summary command button then it copy the master sheet with cell “A6” Name and will hide the Master sheet. Again when you select the another Month name then it will generate the sheet for that month name. o Generate Toll System Uptime ? When I select the sheet name and “Week” then Press the “Enter “Command button then it should get the result from that sheet number . Each sheet number has Month detail in B2 Cell. ? To calculate the Uptime formula for Week wise is • Week-01 = (1680-SUMIFS(L5:L23,B5:B23,"="&B2,B5:B23,"<="&(B2+6)))/1680 • Week-02 =(1680-SUMIFS(L5:L23,B5:B23,"="&(B2+7),B5:B23,"<="&(B2+13)))/1680 • Week-03 =(1680-SUMIFS(L5:L23,B5:B23,"="&(B2+14),B5:B23,"<="&(B2+20)))/1680 • Week-04 =(1680-SUMIFS(L5:L23,B5:B23,"="&(B2+21),B5:B23,"<="&(B2+27)))/1680 • Month =(1680-SUMIFS(L5:L23,B5:B23,"="&(B2),B5:B23,"<="&(DATE(YEAR(B2),1+MONTH(B2),1)-1)))/1680 ? Result should reflect in Summary sheet at B18 cell . o Pending Fault Report Summary ? When segregate the report on its status like which one is open or Close . It is open then it is Pending Fault Report and when it is Close status it means it is closed. ? If any fault which has OPEN status in all sheets(Jan-13,Feb-13,Mar-13….etc) then it should be come as well as in Pending Sheet which ascending date order. ? When it’s status is changed then it should be moved in that month sheet or nearby fault created date. It status is close then it should not be available in pending sheet as it’s status is Closed. ? Each fault has Reported date and we monitor all fault according reported date. ? When we press the Update Fault Report Summary command button then it should update as above logic. ? Some time we export the Pending fault report , so date calendar should be present in Start and End date to Choose the date. When we press the Export command line then it should export the Pending fault report and able to save in Excel,PDF.

• How to synchronise the acceleration, velocity and position of the monsters on the server with the players?

  - by Nick

  I'm building an MMO using Node.js, and there are monsters roaming around. I can make them move around on the server using vector variables acceleration, velocity and position. acceleration = steeringForce / mass; velocity += acceleration * dTime; position += velocity * dTime; Right now I just send the positions over, and tell the players these are the "target positions" of the monsters, and let the monsters move towards the target positions on the client with a speed dependant on the distance of the target position. It works but looks rather strange. How do I synchronise these properly with the players without looking funny to them, taking into account the server lag? The problem is that I don't know how to make use of the correct acceleration/velocity values here; right now they just move directly in a straight line to the target position instead of accelerating/braking there properly. How can I implement such behaviour?

• Is is possible to get a patch included in the current release? If so, how?

  - by Oli

  So a while back I reported a bug in Compiz's Place Window plugin. It's a fairly major regression for people affected by it: mainly those using Gnome-Fallback, judging by the reports. A patch surfaced a short time later. I created a PPA for testing and everybody involved so far is reporting the issues are fixed. It even fixes another bug. I've done testing with a standard Unity desktop and can say (for my testing) no adverse effects were visible. I want to get this pushed to Ubuntu right now for two main reasons: I'm selfish. I don't want to need to update my PPA every time a new version of Compiz is pushed to 12.04. I don't want Ubuntu users seeing their windows flying around because of a silly little bug. I want this patch pushed to Ubuntu's version of Compiz as soon as possible, so we can mark these bugs fixed and move on with our lives. Whose leg do I have to hump to get this pulled into Ubuntu right now? I don't maintain this project and it's an upstream thing but it's fairly integral to Ubuntu. I could go to Compiz but I imagine that if they accept the patch, it'll be months (at least a release) before it's anywhere near Ubuntu. And when I do find the right person, how can I make the process as slick as possible for them? I want them to see my request, go "Yup, that all looks great, done" and that be it. I don't want seventeen rounds of emails addressing aspects of the patch. More importantly, I don't want to waste their time either. And what do I have to provide them? My packaging skills are... lamentable. This was my first attempt at patching a package for redistribution so I've probably made every single packaging error known to man. Will they be happy with the original patch (so they can apply it themselves) or should I repackage things so the diff/changelog is a little cleaner (it took me a few goes and the versioning is all over the place). Note: This question is about Compiz but I'd prefer if answers could address other styles of package too so we have an authoritative and comprehensive thread of how to get things fixed.

• How do you make a bullet ricochet off a vertical wall?

  - by Bagofsheep

  First things first. I am using C# with XNA. My game is top-down and the player can shoot bullets. I've managed to get the bullets to ricochet correctly off horizontal walls. Yet, despite using similar methods (e.g. http://stackoverflow.com/questions/3203952/mirroring-an-angle) and reading other answered questions about this subject I have not been able to get the bullets to ricochet off a vertical wall correctly. Any method I've tried has failed and sometimes made ricocheting off a horizontal wall buggy. Here is the collision code that calls the ricochet method: //Loop through returned tile rectangles from quad tree to test for wall collision. If a collision occurs perform collision logic. for (int r = 0; r < returnObjects.Count; r++) if (Bullets[i].BoundingRectangle.Intersects(returnObjects[r])) Bullets[i].doCollision(returnObjects[r]); Now here is the code for the doCollision method. public void doCollision(Rectangle surface) { if (Ricochet) doRicochet(surface); else Trash = true; } Finally, here is the code for the doRicochet method. public void doRicochet(Rectangle surface) { if (Position.X > surface.Left && Position.X < surface.Right) { //Mirror the bullet's angle. Rotation = -1 * Rotation; //Moves the bullet in the direction of its rotation by given amount. moveFaceDirection(Sprite.Width * BulletScale.X); } else if (Position.Y > surface.Top && Position.Y < surface.Bottom) { } } Since I am only dealing with vertical and horizontal walls at the moment, the if statements simply determine if the object is colliding from the right or left, or from the top or bottom. If the object's X position is within the boundaries of the tile's X boundaries (left and right sides), it must be colliding from the top, and vice verse. As you can see, the else if statement is empty and is where the correct code needs to go.

• Building a Debian package with two buildsystem

  - by queueoverflow

  I have a package that needs to be build with both a regular makefile and a setup.py. The thing is that the Debian packaging magic that is invoked via debuild would recognize a makefile and do the right make make install DESTDIR=??? thing and get it working right. When I only have a setup.py sitting there and have dh $@ --with python3 --buildsystem pybuild in debian/rules, it will correctly install the Python module with python3 setup.py build python3 setup.py install --install-layout deb --root=??? ??? I do not know all those flags. And I think that I do not need to. I just want the makefile magic to happen, and then the setup.py magic. How can I tell debuild to do both? When I do the following in debian/rules %: dh $@ dh $@ --with python3 --buildsystem pybuild it will only put the first one into the resulting package. I tried to delete the debhelper.log between those, but that did not change much.

• When do you change your major/minor/patch version number?

  - by dave4351

  Do you change your major/minor/patch version numbers right before you release or right after? Example: You just released 1.0.0 to the world (huzzah!). But wait, don't celebrate too much. 1.1.0 is coming out in six weeks! So you fix a bug and do a new build. What's that build called? 1.1.0.0 or 1.0.0.xxxy (where xxxy is the build number of 1.0.0 incremented)? Keep in mind you may have 100 features and bugs to go into 1.1.0. So it might be good to call it 1.0.0.xxxy, because you're nowhere close to 1.1.0. But on the other hand, another dev may be working on 2.0.0, in which case your build might be better named 1.1.0.0 and his 2.0.0.0 instead of 1.0.0.xxxy and 1.0.0.xxxz, respectively.

• How do you delete an iFolder from iFolder admin interface

  - by cheshirekow

  There are only two buttons at the bottom of the screen "enable" and "disable". When I check the box next to an iFolder one of them is lit (depending on what the state of the folder is)... but there is no button to delete the folder (as it seems there should be from the documentation). There is a delete button in the "orphaned" tab but how do you "orphan" an iFolder? I'm logged in to the admin interface as admin, who is currently the owner of the folder I wish to delete.

• Glm Vector Transformations [duplicate]

  - by Reanimation

  This question already has an answer here: Car-like Physics - Basic Maths to Simulate Steering 2 answers I have a cube rendered on the screen which represents a car (or similar). Using Projection/Model matrices and Glm I am able to move it back and fourth along the axes and rotate it left or right. I'm having trouble with the vector mathematics to make the cube move forwards no matter which direction it's current orientation is. (ie. if I would like, if it's rotated right 30degrees, when it's move forwards, it travels along the 30degree angle on a new axes). I hope I've explained that correctly. This is what I've managed to do so far in terms of using glm to move the cube: glm::vec3 vel; //velocity vector void renderMovingCube(){ glUseProgram(movingCubeShader.handle()); GLuint matrixLoc4MovingCube = glGetUniformLocation(movingCubeShader.handle(), "ProjectionMatrix"); glUniformMatrix4fv(matrixLoc4MovingCube, 1, GL_FALSE, &ProjectionMatrix[0][0]); glm::mat4 viewMatrixMovingCube; viewMatrixMovingCube = glm::lookAt(camOrigin, camLookingAt, camNormalXYZ); vel.x = cos(rotX); vel.y=sin(rotX); vel*=moveCube; //move cube ModelViewMatrix = glm::translate(viewMatrixMovingCube,globalPos*vel); //bring ground and cube to bottom of screen ModelViewMatrix = glm::translate(ModelViewMatrix, glm::vec3(0,-48,0)); ModelViewMatrix = glm::rotate(ModelViewMatrix, rotX, glm::vec3(0,1,0)); //manually turn glUniformMatrix4fv(glGetUniformLocation(movingCubeShader.handle(), "ModelViewMatrix"), 1, GL_FALSE, &ModelViewMatrix[0][0]); //pass matrix to shader movingCube.render(); //draw glUseProgram(0); } keyboard input: void keyboard() { char BACKWARD = keys['S']; char FORWARD = keys['W']; char ROT_LEFT = keys['A']; char ROT_RIGHT = keys['D']; if (FORWARD) //W - move forwards { globalPos += vel; //globalPos.z -= moveCube; BACKWARD = false; } if (BACKWARD)//S - move backwards { globalPos.z += moveCube; FORWARD = false; } if (ROT_LEFT)//A - turn left { rotX +=0.01f; ROT_LEFT = false; } if (ROT_RIGHT)//D - turn right { rotX -=0.01f; ROT_RIGHT = false; } Where am I going wrong with my vectors? I would like change the direction of the cube (which it does) but then move forwards in that direction.

• Run external application on markdown source in ikiwiki

  - by student

  Can I add a button to each wiki page in ikiwiki which launches an external application (on the client side) or script with the markdown code of the current page as input? Edit: I didn't realize that it might be complicated to do it on client side as Zenklys' answer suggested. So perhaps I should describe more concretely what I have in mind: I want to have two buttons: "Get LaTeX" and 2. "Get pdf". Clicking on "Get LaTeX should generate a LaTeX file and the browser should simply open or download that file. Analogously for the pdf. It would even be ok, to have a button "Generate LaTeX" instead, which generates the LaTeX code and changes after the generation to "Get LaTeX" which simply points to the LaTeX file. So it is not really necessary to do the generation of the files on client side. Would be ok, if this is done (on a temporary folder) on server side. For the LaTeX resp. pdf generation I want to use a custom wrapper script for pandoc, let's call it mymarkdown2latex resp. mymarkdown2pdf.

• Auto-organized / smart inventory system?

  - by VeXe

  for the past week I've been working on an inventory system with Unity3D. At first I got help from the guys at Design3 but it wasn't too long till we split path, because I really didn't like the way they did their code, it didn't have any smell of OOP whatsoever. I took it further steps ahead - items take more than one slot, advanced placement system (items tries their best to find the best close fit), local mouse system (mouse gets trapped in active bag area), etc. Here's a demo of my work. What we would like to have in our game, is an auto-organizing feature - not auto-sort. We want this feature because our inventory's going to be in 'real-time' - not like in Resident Evil 1,2,3 etc where you would pause the game and do things in your inventory. Now imagine your self in a sticky situation surrounded by zombies, and you don't have bullets, you look around, you see that there are bullets nearby on the ground, so you go for them and try to pick them up, but they don't fit! you look at your inventory and find out that if you reorganize some of the items, it will fit! - now the player - in that situation doesn't have time to reorganize because he's surrounded with zombies and will die if he stops and organizes the inventory to make space (remember inventory in real-time, no pausing) - wouldn't it be nice for that to happen automatically? - Yes! (I believe this has been implemented in some games like Dungeon siege or something, so sure it's doable) take a look at this picture for example: Yes, so if you auto-sort the issue you will get your spaces but it's bad because: 1- Expensive: it doesn't need a whole sort operation to free those spaces, in the first picture, just slide the red item at the bottom to the very left, and you get the same spaces that you got from the auto-sort. 2- It's annoying to the player: "Who the F told you to re-order my stuff?" I'm not asking for "How to write the code" for this, I'm just asking for some guidance, where to look, what algorithms are involved? Is this something related to graphs and shortest path stuff? I hope not cuz I didn't manage to continue my college studies :/ But even if it is, just tell me and I will learn the stuff related. Notice there could be more than just one solution. So I guess the first thing I have to do is figure out if the situation is 'solvable' - if I know how to determine if a situation is solvable or not, then I can 'solve' it. I just need to know the conditions that makes it 'solvable'. And I believe there must be some algorithm/data structure for this. Here's a pic for more than one solution of trying to fit a 1x3 item: The arrows show just one of the solutions, but if you look you will find more than one. This is what I ultimately not auto-sorting but find a solution and applying it. Note that if I spend time on it I will come up with a way to solve it, but it wouldn't be the best way, it's like, holding a car wheel with your feet instead of your hands! XD Or just like trying to solve an issue that requires arrays, but you're not yet aware of their existence! So what is the right approach to this? Hope somebody helps, thanks a lot in advance :)

• How do I make my "volume up" more powerful in Win7?

  - by joon

  My volume up button raises the volume by 1%. Its also not a button, it's a weird 'touch' thing which is really really terrible. If I want to lower the volume, I have to awkwardly rub it for a while. If it were to decrease by 5% or 10% it would be a lot better. Can this be set somewhere in Windows/Keyboard settings? I got close to a solution with Autohotkey, where I could do this: a::Send {Volume_Up 5} which would send the volume up command five times, however when I assign it to the volume key, it forms an endless loop since the Send command sends Volume_Up and parses it at the same time. Update: I ended up with this script: $Volume_Up::VolumeUp() $Volume_Down::VolumeDown() VolumeUp( ) { Send {Volume_Up 6} SoundBeep, 750, 50 } VolumeDown( ) { Send {Volume_Down 6} SoundBeep, 750, 50 }

• Can't boot from USB - 11.04 / Exopc

  - by Charles

  I can't find the answer to this anywhere. I am new to Ubuntu, please help! I have a wetab, except now I don't, because I put Ubuntu 10.10 over the top of it (meant to dual boot, but that's another story). I upgraded to 11.04 out of curiosity. It's good, but not for touchscreen tablets - no multi touch for example. I want to get back the wetab OS now. I have all the files, and I have a bootable gparted USB stick. The problem is I can't seem to boot from USB. The "wetab" PC is actually an ExoPC, so it has only the hardware button and a soft button in the top corner. Using the wetab OS method of reaching BIOS with the hard and soft buttons doesn't work now, I only get a menu asking if I want to run Ubuntu in recovery mode, run a limited command line, or do a memory check. I need to either repartition the drive so I can dual boot with WeTabOS, or just wipe over Ubuntu and start again. How do I do this? I have also tried hammering F11, Del, F8, F1, many other combinations! Edit: I do have access to USB keyboard and mouse

• Unity3D : Pause Menu - Android

  - by user3666251

  Im making a 2D game for android.I almost completed the game but now I need a pause game option.I added a pause icon on the top right side of the screen.The icon is a gui texture.Here is what I did so far : I made a script which will bring up some buttons (which is not working) and attached it to the GUITexture.This is the script : #pragma strict function OnMouseDown() { Debug.Log("*Pause Menu Opens*"); Time.timeScale = 0; if (GUI.Button(Rect(10,10,100,50),"Restart")); Application.LoadLevel(Application.loadedLevel); if (GUI.Button(Rect(10,60,100,50),"MainMenu")); Application.LoadLevel("MainMenu"); } Now,the problem stands at the part where the buttons won't show up,the game freezes at the first frame but the buttons won't show up.Please,if you can help I would be realy thankful. Thank you. Edit #1 : I just noticed that when I click "Pause" the game freezes and it takes me to the MainMenu.That's because I added the GUIButton which takes you to the main menu.I think the whole script structure is wrong.I also forgot to mention that Im new in scripting/unity. Thank you.
