• Huge surge in direct traffic from one particular town

  - by Jack Lockyer

  Last month I noticed that the direct visits on our site have increased by nearly 150% whilst bounce rate is also considerably up. After drilling down further I can see that we have had nearly 2000 direct visits from one town in Connecticut called Stamford, with a bounce rate of 100%! I have been scratching around for answers but I can only find that it may be to do with our uptime monitoring tool; Pingdom. Does anyone know/have any experience with this kind of issue, any help is appreciated I have just noticed that we are receiving identical traffic in a town in England and a town in Scotland... This definitely makes me think it's to do with our uptime monitoring tool.

• Is it possible that Unity would some day switch back to Mutter?

  - by David

  I remembered that the first Unity was indeed built on Mutter, but later ported to Compiz due to poor performance. I also know Canonical practically incorporated Compiz to work closely for future Unity, so this is getting less likely. But Compiz just seems pretty outdated now that GNOME3/GTK3/Mutter is becoming more mainstreamed, and it is known to deliver some performance issue, but on the other hand Mutter seems pretty good and is still steadily developing now, I'm just wondering if anyone related to the project is still testing and evaluating the possibility of Unity on Mutter? Not that you have to tell me now if you're going to do it or not. I just wanna know if anyone is considering it. Thanks.

• Unity: Assigning String value in inspector

  - by Marc Pilgaard

  I got an issue with Unity I can't seem to comprehend, and it is possibly very simple: I am trying to write a simple piece of code in JavaScript where a button toggles the activation of a shield, by dragging a prefab with Resources.load("ActivateShieldPreFab") and destroying it again (Haven't implemented that yet). I wish to assign this button through the inspector, so I have created a string variable which appears as intended in the inspector. Though it doesn't seem to register the inspector input, even though I changed the value through the inspector. It only provides the error: "Input Key named: is unknown" When the button name is assigned within the code, there is no issues. Code as follows: var ShieldOn = false; var stringbutton : String; function Start(){ } function Update () { if(Input.GetKey(stringbutton) && ShieldOn != true) { Instantiate(Resources.load("ActivateShieldPreFab"), Vector3 (0, 0, 0), Quaternion.identity); ShieldOn = true; } } Hope somebody can help, in advance... Thanks

• La Libye coupe ses accès Internet, certains craignent l'indisponibilité des URL réduites de bit.ly

  La Libye coupe ses accès Internet, certains craignent l'indisponibilité des URL réduites de bit.ly On ne rigole plus en Libye. Le pays, soulevé depuis quelques jours par les opposants au régime politique en place, est de plus en plus agité. Face à cela, le pouvoir libyen craint de voir arriver la même issue qu'en Egypte. Aussi, depuis vendredi, le réseau social Facebook n'est plus accessible dans le pays. Mais ce n'est pas tout. Muammar Kadhafi a également demandé une coupure de l'Internet local, et le dirigeant ne s'adresse plus aux médias. Puis, la Toile a été accessible par intermittences : quelques fois, les sites sont lents, d'autres fois, ils sont inaccessibles. Apparemment, une embellie aurait...

• Additional Drivers error installing in Ubuntu 12.04 (wireless internet and software modem)

  - by gabiro

  I've already search for similar problems but they are so different from mine. these are the drivers http://db.tt/qFZlD5JD I'm having problem with this Additional Drivers once I click the Activate button it will start in downloading and installing but after that it will say Installation failed. Then the "Enable Wireless" will not be available. With the Software Modem issue is the same problem with the Broadcom. These drivers are working on Ubuntu 9 and 11 if I'm not mistaken. Only on 12.04 is not working. One more thing these drivers will enable the Huawei E165g E220. I've already tried other solution for the Huawei to activate but all didn't work. After a restart Enable wireless becomes okay, though. To all Ubuntu experts and masters please I'm begging for help. A million Thank You!.

• Octrees as data structure

  - by Christian Frantz

  In my cube world, I want to use octrees to represent my chunks of 20x20x20 cubes for frustum and occlusion culling. I understand how octrees work, I just dont know if I'm going about this the right way. My base octree class is taken from here: http://www.xnawiki.com/index.php/Octree What I'm wondering is how to apply occlusion culling using this class. Does it make sense to have one octree for each cube chunk? Or should I make the octree bigger? Since I'm using cubes, each cube should fit into a node without overlap so that won't be an issue

• Creating a DrawableGameComponent

  - by Christian Frantz

  If I'm going to draw cubes effectively, I need to get rid of the numerous amounts of draw calls I have and what has been suggested is that I create a "mesh" of my cubes. I already have them being stored in a single vertex buffer, but the issue lies in my draw method where I am still looping through every cube in order to draw them. I thought this was necessary as each cube will have a set position, but it lowers the frame rate incredibly. What's the easiest way to go about this? I have a class CubeChunk that inherits Microsoft.Stuff.DrawableGameComponent, but I don't know what comes next. I suppose I could just use the chunk of cubes created in my cube class, but that would just keep me going in circles and drawing each cube individually. The goal here is to create a draw method that draws my chunk as a whole, and to not draw individual cubes as I've been doing.

• I want to record a screencast of a processing sketch

  - by nathanvda

  I have a created a music visualisation using Processing. I now want to convert that to a video, and the least obtrusive way I could think of is to record a screencast. I figured exporting Processing to video including audio, from within Processing itself, on ubuntu seemed an unsolved issue. Very hard and also could cause timing sync issues (since the music keeps running while images are captured). So move on to the screencast method. Dead-easy, I figured. But I was wrong. First hurdle was to find a way to record the sound from the audio (and not the mic). I did find a tutorial for that here. In short: use gtk-recordmydesktop and pulse audio. But, apparently, what happens: Processing does not use ALSA. When the sound is playing, it does not appear in the Pulse Audio mixer. How can I record the audio now?

• Problems with the colors on my screen. How can I check if it's a hardware problem?

  - by Ingo Gerth

  On my EEE PC netbook some colors are not displayed properly. Specifically, dark gradients such as in the window title do not look very smooth, but rather look like a sequence of a couple of different colors. This is especially visible when opening a menu, for example the "File" menu in Firefox. As you know this one is black, and it looks terrible on my screen. It is not just black, but the colors look really graded and far from a smooth gradient or anything. Now I am wondering: Is this a hardware or software issue? And how can I check this? If it should be a fixable problem I think it would be worth another question. Note that I am using Natty. If my problem description is not good enough I can try to take a photo.

• IntelliTrace collector error Some or all identity references could not be translated

  - by Tarun Arora

  If you are running the IntelliTrace stand alone collector to collect the trace against an Application Pool which is running under the identity “.\<username>” then you are likely to run into the following exception, Start-IntelliTraceCollection : Some or all identity references could not be translated. At line:1 char:29 + Start-IntelliTraceCollection <<<<  "FabrikamFiber.Web" C:\IntelliTraceCTP\collection_plan.ASP.NET.trace.xml C:\Intell iTraceLogs     + CategoryInfo          : NotSpecified: (:) [Start-IntelliTraceCollection], IdentityNotMappedException     + FullyQualifiedErrorId : System.Security.Principal.IdentityNotMappedException,Microsoft.VisualStudio.IntelliTrace    .PowerShell.StartIntelliTraceCollectionCommand   Steps to reproduce the issue The application pool “FabrikamFiber.Web” is using the identity “.\Admin”   Workaround Change the identity of the application pool to <MachineName|Domain>\<UserName>. So, in the above work around if I change the identity to “Production\Admin” then the IntelliTrace does not throw an exception. This error has been reported to Microsoft and it is expected that it will be fixed in one of the future releases. Enjoy!

• How can I obtain in-game data from Warcraft 3 from an external process?

  - by Slav

  I am implementing a behavior algorithm and would like to test it with my lovely Warcraft III game to watch how it will fight against real players. The problem I'm having is that I don't know how to obtain information about in-game state (units, structures, environment, etc.) from the running WC3 game. My algorithm needs access to the hard drive and possibly distributed computing, that's why JASS (WC3's editor language) isn't appropriate; I need to run my algorithm from a separate process. Direct3D hooking is an approach, but it wasn't done for WC3 yet and a significant drawback of that approach would be the inability to watch how the AI performs online, since it uses the viewport to issue commands. How I read in-game data from WC3 in a different process in a fastest and easiest way?

• Sceptic in a SCRUM Team

  - by Sorantis

  My company has recently switched to an Agile WoW and as a part of it we've started using SCRUM. While I'm very comfortable with it and feel that this WoW is superior to a traditional one, some of my teammates don't share the same opinion. In fact they are very skeptical about "all that agile stuff", and don't take it seriously. As an example, one of the teammates is always late on the meetings, and doesn't really care about it. The management IMO tries not to notice this (maybe because it's a new Wow, and it takes time for the people to get used to it). My question is, how to address this issue not raising a conflict inside the team?

• Images Loading Very Slowly

  - by Vecta

  I'm currently working on optimizing my site to try to decrease load time by using Pingdom tools. I seem to be having some difficulty with long load times on images. For example, the body background for my site is a 29kb file but takes almost 500 ms to load, the majority of which is spent connecting to the server. This one seems to take the longest times but other images seem to take a lot of time as well—the majority of which seems to be spent connecting to the server. This also seems to fluctuate as I've seen the same image load in 500ms one minute and ten minutes later load in 1.5 seconds. My site is using the Modx CMS but I'm not sure if that would affect this at all. Is it more likely that this is a server issue? Is there anything that I should check or do to help alleviate these inflated 'connect' times?

• Library search paths

  - by David Clements

  This question originally started in an apparent problem in Cups calling various back-ends and using non-standard library search paths. If I want to change a library search path for a app running in a terminal I can use LD_LIBRARY_PATH, RPATH, etc., but if I want to change a library path for a Cups back end, I subsequently resolved the Cups issue, but I don't see any mechanism to change the search path whare an app is not running in terminal. For example Cups calls backendA and backendB to print on 2 printers, BackendA uses libxxx.1.15 and BackendB needs libxxx.1.05, is there any way to change the library search path for backendB (only) without recompiling backendB, (I may not have the source)? Any ideas?

• Booting but not rebooting from external USB hard drive, what could be the problem?

  - by user8276

  I have a Dell Inspiron 6400 laptop with a dead internal hard drive controller. It boots perfectly from CD or USB. I therefore removed the internal hard drive and installed Ubuntu 10.10 Maverick onto an external USB hard drive. It boots and runs perfectly when doing a "cold start" of the PC. However, when I choose restart/reboot in the Ubuntu menu (e.g. after an update), I get this error message from the BIOS: "No bootable devices, strike f1 to retry boot, f2 for setup utility, press f5 to run onboard diagnostics". I can make the system boot again by pressing f2 or f5 and exiting the utility without having done anything. Or, I can simply power off the system and do a new "cold start". Does anyone know the likely reason for this problem and how to fix it. It is not a big issue but an annoyance that I would like to fix if possible.

• Record and display Kinect audio and video via avconv

  - by ThomasH

  I'm trying to record audio and video from a Kinect using avconv but I seem to have trouble specifying the right options. avconv -f video4linux2 -video_size 640x480 -c:v h264 -c:a ac3 -i /dev/video1 test.mp4 results in: avconv: /build/buildd/libav-extra-0.8.3ubuntu0.12.04.1/libav/libavutil/mathematics.c:79: av_rescale_rnd: Assertion `c > 0' failed. Aborted (core dumped) Cheese is perfectly happy recording the audio and video from the Kinect, so it's not a setup issue. For added fun, I also need to display the video at the same time.

• Recovering a deleted partition

  - by Kishore

  I had a dual boot PC running Ubuntu 12.04 and Windows 7. About a month back, I deleted the Ubuntu partition via the disk management utility (I do not remember whether or not I formatted the partition after performing this action). I ran into some grub issues and used lilo to solve the issue. I followed the simple instructions described in this blog post. I now realize that there were some files in the Ubuntu installation that I need. Of course, I backed up the data, but not this folder apparently. Is there any way to get the data back? I tried following the process suggested on another post on askubuntu (suggesting the use of TestDisk), but was not able to even install TestDisk. The live USB I use is running Ubuntu 12.04 and it does not have a synaptic package manager. Installing from the terminal does not work because even after I type: sudo apt-get update sudo apt-get upgrade the command: sudo apt-get install testdisk fails to work.

• VNC Server not responsive after a few days

  - by assylias

  I am new to Ubuntu (11.10) - I installed Ubuntu on a box which has no screen and no keyboard. I connect to that box via tightvncserver. The box is mostly used as a file and media server (i.e. samba + XBMC). So far so good. I can connect via VNC to the box and take control of it. But after a few days, when trying to connect via VNC, I don't get a response. The media server is still on, ping is fine, but VNC is down. The only solution I have found is to plug a screen and keyboard and reboot. I am not sure how to diagnose the problem (maybe some log files?) or if this is just a configuration issue. Any help appreciated.

• Associating Palettes with View TopComponents

  - by Geertjan

  A side effect of changes in NetBeans Platform 7.1 in the NetBeans window system is that palettes can now be created for view TopComponents. Below, a TopComponent in the "explorer" position is selected, which results in the Palette opening and showing items that can be dragged into the TopComponent: And here, in the same application, a TopComponent in the "output" position is now selected, which causes the Palette to open, showing items that are relevant to the TopComponent: I copied code used in the above two TopComponents from this blog entry: https://blogs.oracle.com/geertjan/entry/simple_component_palette Related issue: http://netbeans.org/bugzilla/show_bug.cgi?id=209238

• blurry images with mogrify & convert

  - by user140393

  Does anyone know why this image is so blurry? I did a convert from pdf to png and it turned out like that. Before deleting imagemagick and it's entire toolset from software-center most of my image programs were displaying like this image. Now for the most part it's just blurry, though a couple still display like that such as gimp. I am running in xfce maybe it's to do with the distribution enviornment. Main issue is the absurd blurriness. I reinstalled all additional packages that were available for imagemagick in the software-center I use convert *.pdf *.png & mogrify -format png *.pdf to convert Now on the other hand if I converted the file to djvu and converted that to a tif. The images have no problem converting. More so it does not generate an oversized tif file of around 25mb compared to 3mb with djvu which is super clear & no blurriness.

• PyQt design issues

  - by Falmarri

  I've been working on a my first real project using PyQt lately. I've done just a little bit of work in Qt for C++ but nothing more than just messing around. I've found that the Qt python bindings are essentially just a straight port of C++ classes into python, which makes sense. The issue is that this creates a lot of messy, unpythonic code. For example if you look at QAbstractItemModel, there's a lot of hoops you have to go through that forces you to hide the actual python. I was just wondering if there's any intention of writing a python implementation of Qt that isn't necessarily just a wrapper? Either by Nokia or anyone else? I really like Qt but I would love to be able to write more pythonic code. I hope this is OK to ask here. I'm not trying to start a GUI war or anything.

• viewing fbx files in windows via xna 4.0

  - by user17753

  I've made some models in Blender and exported them in Autodesk fbx format. I'm trying to view them using XNA 4.0 Refresh. Loading them isn't much an issue, but I'm not familiar enough with XNA 4.0 to, well basically I want to load in the model at say the origin (0,0,0) world coordinates, and then rotate and/or zoom the camera about the world coordinates origin as well so that I can test the model. Typically the mouse, and maybe some arrow keys for zooming/rotating the camera. Anyways, this seems like a simple task and I shouldn't have to re-invent this, isn't there a skeleton code somewhere for this kind of thing for XNA 4.0? I couldn't find a solid example for this on the web. I found a couple that seemed like they might work for xbox, but I'm trying to do this on windows only. Anyways, just looking to be pointed in the right direction on this one, thanks.
