• PC hangs and reboots from time to time

  - by Bevor

  Hello, I have a very strange problem: Since I have my new PC, I have always had problems with it. From time to time the computer freezes for some seconds and suddendly reboots by itself. I've had this problem since Ubuntu 9.10. The same with 10.04 and 10.10. That's why I don't think it's a software failure because the problem persist too long. It doesn't have anything to do with what I'm doing at this time. Sometimes I listen to music, sometimes I only use Firefox, sometimes I'm running 2 or 3 VMs, sometimes I watch DVD. So it's not isolatable. I could freeze once a day or once a week. I put the PC to the vendor twice(!). The first time they changed my power supply but the problem persisted. The second time they told me that they made some heavy performance tests 50 hours long but they didn't find anything. (How can that be that I have daily freezes with normal usage). The vendor didn't check the hard discs because they used their own disc with Windows. (So they never checked the Linux installation). Yesterday I made some intensive hard disc scans with "SMART" but no errors were found. I ran memtest for 3 times but no errors found. I already had this problem in my old flat, so I doubt that I has something to do with current fluctuation. I already tried another electrical socket and changed to connector strip but the problem persists. At the moment I removed 2 of the RAMs (2x 2GB). In all I have 6GB, 2x2GB and 2x1GB. Could this difference maybe be a problem? Here is a list of my components. I hope that anybody find something I didn't think about yet.

• WordPress not resizing images with Nginx + php-fpm and other issues

  - by Julian Fernandes

  Recently i setup a Ubuntu 12.04 VPS with 512mb/1ghz CPU, Nginx + php-fpm + Varnish + APC + Percona's MySQL server + CloudFlare Pro for our Ubuntu LoCo Team's WordPress blog. The blog get about 3~4k daily hits, use about 180MB and 8~20% CPU. Everything seems to be working insanely fast... page load is really good and is about 16x faster than any of our competitors... but there is one problem. When we upload a image, WordPress don't resize it, so all we can do it insert the full image in the post. If the imagem have, let's say, 30kb, it resize fine... but if the image have 100kb+, it won't... In nginx error logs i see this: upstream timed out (110: Connection timed out) while reading response header from upstream, client: 150.162.216.64, server: www.ubuntubrsc.com, request: "POST /wp-admin/async-upload.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "www.ubuntubrsc.com", referrer: "http://www.ubuntubrsc.com/wp-admin/media-upload.php?post_id=2668&" It seems to be related with the issue, but i dunno. When that timeout happens, i started to get it when i'm trying to view a post too: upstream timed out (110: Connection timed out) while reading response header from upstream, client: 150.162.216.64, server: www.ubuntubrsc.com, request: "GET /tutoriais-gimp-6-adicionando-aplicando-novos-pinceis.html HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "www.ubuntubrsc.com", referrer: "http://www.ubuntubrsc.com/" And only a restart of php5-fpm fix it. I tryed increasing some timeouts and stuffs but it did not worked, so i guess it's some kind of limitation i did not figured yet. Could someone help me with it, please? /etc/nginx/nginx.conf: user www-data; worker_processes 1; pid /var/run/nginx.pid; events { worker_connections 1024; use epoll; multi_accept on; } http { ## # Basic Settings ## sendfile on;

Sorry for my bad english and thanks for your time people! (:

• DirectX works for 64-bit but not 32-bit

  - by dtbarne

  I'm trying to play a game (Civilization 5) which was previously working but no longer. I believe I've narrowed it down to a DirectX issue because I get an error running dxdiag.exe in 32 bit mode. My goal (at least I believe) is to get Direct3D Acceleration "Enabled" in dxdiag (as it is in 64 bit dxdiag). A very similar issue is here: http://answers.microsoft.com/en-us/windows/forum/windows_7-gaming/direct3d-acceleration-is-not-available-in-windows/4c345e6e-dc68-e011-8dfc-68b599b31bf5?page=1 The proposed answer, which looks very promising, doesn't seem to work for me. Like other users in that thread, HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Direct3D\Drivers does not have a SoftwareOnly key to change. I even tried manually adding it as a string and dword, to no avail. I have a NVIDIA GeForce GT 525M, and before you ask, yes I've tried updating (also uninstalling, reinstalling) my drivers. I've also tried doing the same with DirectX (and Civilization 5 for that matter). Been debugging for some 4+ hours now after a full day of work and I've run out of ideas. I'm hoping somebody knows the solution here! :) Here's what I see when I open dxdiag: DxDiag has detected that there mgiht have been a problem accessing Direct3D the last time this program was used. Would you like to bypass Direct3D this time? No - Crash Yes - Works, but in Display tab: DirectDraw Acceleration: Disabled Direct3D Acceleration: Not Available AGP Texture Acceleration: Not Available If I click "Run 64-bit DxDiag", all three are "Enabled". I should also note that I've tried the following steps as Microsoft suggests, but I'm not able to do so as the "Change Settings" button is disabled. Some programs run very slowly—or not at all—unless Microsoft DirectDraw or Direct3D hardware acceleration is turned on. To determine this, click the Display tab, and then under DirectX Features, check to see whether DirectDraw, Direct3D, and AGP Texture Acceleration appear as Enabled. If not, try turning on hardware acceleration. Click to open Screen Resolution. Click Advanced settings. Click the Troubleshoot tab, and then click Change settings. If you're prompted for an administrator password or confirmation, type the password or provide confirmation. Move the Hardware Acceleration slider to Full.

• How to reduce RAM consumption when my server is idle

  - by Julien Genestoux

  We use Slicehost, with 512MB instances. We run Ubuntu 9.10 on them. I installed a few packages, and I'm now trying to optimize RAM consumption before running anything on there. A simple ps gives me the list of running processes : # ps faux USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 2 0.0 0.0 0 0 ? S< Jan04 0:00 [kthreadd] root 3 0.0 0.0 0 0 ?

Quite disapointing! 2 questions arise : Where is all this memory? How to take some of it back for my own apps?

• Wired connection periodically disconnects requires ipconfig /release and /renew to reconnect

  - by Sesame

  I just got back into University and after a day of using the internet I suddenly was unable to visit other webpages even though I was still able to chat. I restarted the computer and the internet could no longer visit webpages at all. I got a DNS error from the browser (chrome) and the troubleshooter. The connection comes up as "Network 3" even though It was "Network 2" when it worked. I compared ipconfig /all logs and they seemed identical when it was and was not working. I've found two ways to get internet connection (they no longer work): run ipconfig /release and ipconfig /renew several times set a random address and have the troubleshooter fix the new found dhcp problem (before it says dns cannot fix). I checked and it said DHCP was enabled. But either step one or two usually needs to be repeated several times before the network will change back to "network 2" from the defunct "network 3" and after an hour or so I have problems again. I've tried: Uninstalling windows defender and turning off firewall (windows firewall). Updating Qualcomm Ethernet driver - it is up to date. System Restore (problem resurfaces quickly...it's possible this has something to do with windows update?) Flushing dns and setting dns myself (google one and others). Booting in safe mode with networking...didn't fix anything Reinstalling Ethernet Driver Using other ethernet cable, other wall port. I'm out of ideas.

Events cannot be delivered through this filter until the problem is corrected. By the way, Operating System: Windows 7 - 64 Bit. Have downloaded latest windows updates.

This is now what happens when I try to Ipconfig /renew: C:\Users\Nikko\Desktop>ipconfig /renew Windows IP Configuration An error occurred while renewing interface Local Area Connection : The name spec ified in the network control block (NCB) is in use on a remote adapter. The NCB is the data. An error occurred while releasing interface Loopback Pseudo-Interface 1 : The sy stem cannot find the file specified. Update 2: So my internet is randomly working again today. The IP address I had before was a local one while the university address should start with 155... I didn't do anything to the settings...it's bizarre that it all of a sudden works. Thanks!

• Javascript or CSS hover not working in Safari and Chrome

  - by PAZtech

  I have a problem with a script for a image gallery. The problem seems to only occur on Safari and Chrome, but if I refresh the page I get it to work correctly - weird! Correct function: The gallery has a top bar, which if you hover over it, it will display a caption. Below sits the main image. At the bottom there is another bar that is a reversal of the top bar. When you hover over it, it will display thumbnails of the gallery. The problem: In Safari and Chrome, the thumbnail holder will not display. In fact, it doesn't even show it as an active item (or a rollover). But oddly enough, if you manually refresh the page it begins to work correctly for the rest of the time you view the page. Once you have left the page and return the same error occurs again and you have to go through the same process. Here's one of the pages to look at: link text Here's the CSS: #ThumbsGutter { background: url(../Images/1x1.gif); background: url(/Images/1x1.gif); height: 105px; left: 0px; position: absolute; top: 0px; width: 754px; z-index: 2; } #ThumbsHolder { display: none; } #ThumbsTable { left: 1px; } #Thumbs { background-color: #000; width: 703px; } #Thumbs ul { list-style: none; margin: 0; padding: 0; } #Thumbs ul li { display: inline; } .Thumbs ul li a { border-right: 1px solid #fff; border-top: 1px solid #fff; float: left; left: 1px; } .Thumbs ul li a img { filter: alpha(opacity=50); height: 104px; opacity: .5; width: 140px; } .Thumbs ul li a img.Hot { filter: alpha(opacity=100); opacity: 1; } Here is the javascript: //Variables var globalPath = ""; var imgMain; var gutter; var holder; var thumbs; var loadingImage; var holderState; var imgCount; var imgLoaded; var captionHolder; var captionState = 0; var captionHideTimer; var captionHideTime = 500; var thumbsHideTimer; var thumbsHideTime = 500; $(document).ready(function() { //Load Variables imgMain = $("#MainImage"); captionHolder = $("#CaptionHolder");

• Optimizing transition/movement smoothness for a 2D flash game.

  - by Tom

  Update 6: Fenomenas suggested me to re-create everything as simple as possible. I had my doubts that this would make any difference as the algorithm remains the same, and performance did not seem to be the issue. Anyway, it was the only suggestion I got so here it is: 30 FPS: http://www.feedpostal.com/test/simple/30/SimpleMovement.html 40 FPS: http://www.feedpostal.com/test/simple/40/SimpleMovement.html 60 FPS: http://www.feedpostal.com/test/simple/60/SimpleMovement.html 100 FPS: http://www.feedpostal.com/test/simple/100/SimpleMovement.html The code: package { import flash.display.Sprite; import flash.events.Event; import flash.events.KeyboardEvent; import flash.utils.getTimer; [SWF(width="800", height="600", frameRate="40", backgroundColor="#000000")] public class SimpleMovement extends Sprite { private static const TURNING_SPEED:uint = 180; private static const MOVEMENT_SPEED:uint = 400; private static const RADIAN_DIVIDE:Number = Math.PI/180; private var playerObject:Sprite; private var shipContainer:Sprite; private var moving:Boolean = false; private var turningMode:uint = 0; private var movementTimestamp:Number = getTimer(); private var turningTimestamp:Number = movementTimestamp; public function SimpleMovement() { //step 1: create player object playerObject = new Sprite(); playerObject.graphics.lineStyle(1, 0x000000); playerObject.graphics.beginFill(0x6D7B8D); playerObject.graphics.drawRect(0, 0, 25, 50); //make it rotate around the center playerObject.x = 0 - playerObject.width / 2; playerObject.y = 0 - playerObject.height / 2; shipContainer = new Sprite(); shipContainer.addChild(playerObject); shipContainer.x = 100; shipContainer.y = 100; shipContainer.rotation = 180; addChild(shipContainer); //step 2: install keyboard hook when stage is ready addEventListener(Event.ADDED_TO_STAGE, stageReady, false, 0, true); //step 3: install rendering update poll addEventListener(Event.ENTER_FRAME, updatePoller, false, 0, true); } private function updatePoller(event:Event):void { var newTime:Number = getTimer(); //turning if (turningMode != 0) { var turningDeltaTime:Number = newTime - turningTimestamp; turningTimestamp = newTime; var rotation:Number = TURNING_SPEED * turningDeltaTime / 1000; if (turningMode == 1) shipContainer.rotation -= rotation; else shipContainer.rotation += rotation; } //movement if (moving) { var movementDeltaTime:Number = newTime - movementTimestamp; movementTimestamp = newTime; var distance:Number = MOVEMENT_SPEED * movementDeltaTime / 1000; var rAngle:Number = shipContainer.rotation * RADIAN_DIVIDE; //convert degrees to radian shipContainer.x += distance * Math.sin(rAngle); shipContainer.y -= distance * Math.cos(rAngle); } } private function stageReady(event:Event):void { //install keyboard hook stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDown, false, 0, true); stage.addEventListener(KeyboardEvent.KEY_UP, keyUp, false, 0, true); } private final function keyDown(event:KeyboardEvent):void { if ((event.keyCode == 87) && (!moving)) //87 = W { movementTimestamp = getTimer(); moving = true; } if ((event.keyCode == 65) && (turningMode != 1)) //65 = A { turningTimestamp = getTimer(); turningMode = 1; } else if ((event.keyCode == 68) && (turningMode != 2)) //68 = D { turningTimestamp = getTimer(); turningMode = 2; } } private final function keyUp(event:KeyboardEvent):void { if ((event.keyCode == 87) && (moving)) moving = false; //87 = W if (((event.keyCode == 65) || (event.keyCode == 68)) && (turningMode != 0)) turningMode = 0; //65 = A, 68 = D } } } The results were as I expected. Absolutely no improvement. I really hope that someone has another suggestion as this thing needs fixing. Also, I doubt it's my system as I have a pretty good one (8GB RAM, Q9550 QuadCore intel, ATI Radeon 4870 512MB). Also, everyone else I asked so far had the same issue with my client. Update 5: another example of a smooth flash game just to demonstrate that my movement definitely is different! See http://www.spel.nl/game/bumpercraft.html Update 4: I traced the time before rendering (EVENT.RENDER) and right after rendering (EVENT.ENTER_FRAME), the results: rendering took: 14 ms rendering took: 14 ms rendering took: 12 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 14 ms rendering took: 12 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 14 ms rendering took: 12 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 14 ms rendering took: 14 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 24 ms rendering took: 18 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 232 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms The range is 12-16 ms. During these differences, the shocking/warping/flickering movement was already going on. There is also 1 peak of 232ms, at this time there was a relatively big warp. This is however not the biggest problme, the biggest problem are the continuous small warps during normal movement. Does this give anyone a clue? Update 3: After testing, I know that the following factors are not causing my problem: Bitmap's quality - changed with photoshop to an uglier 8 colours optimized graphic, no improvement at all. Constant rotation of image while turning - disabled it, no improvement at all Browser rendering - tried to use the flash player standalone, no improvement at all I am 100% convinced that the problem lies in either my code or in my algorithm. Please, help me out. It has been almost two weeks (1 week that I asked this question on SO) now and I still have to get my golden answer. Update 1: see bottom for full flex project source and a live demo demonstrating my problem. I'm working on a 2d flash game. Player ships are created as an object: ships[id] = new GameShip(); When movement and rotation information is available, this is being directed to the corresponding ship: ships[id].setMovementMode(1); //move forward Now, within this GameShip object movement works using the "Event.ENTER_FRAME" event: addEventListener(Event.ENTER_FRAME, movementHandler); The following function is then being run: private final function movementHandler(event:Event):void { var newTimeStamp:uint = UtilLib.getTimeStamp(); //set current timeStamp var distance:Number = (newTimeStamp - movementTimeStamp) / 1000 * movementSpeed; //speed = x pixels forward every 1 second movementTimeStamp = newTimeStamp; //update old timeStamp var diagonalChange:Array = getDiagonalChange(movementAngle, distance); //the diagonal position update based on angle and distance charX += diagonalChange[0]; charY += diagonalChange[1]; if (shipContainer) { //when the container is ready to be worked with shipContainer.x = charX; shipContainer.y = charY; } } private final function getDiagonalChange(angle:Number, distance:Number):Array { var rAngle:Number = angle * Math.PI/180; //convert degrees to radian return [Math.sin(rAngle) * distance, (Math.cos(rAngle) * distance) * -1]; } When the object is no longer moving, the event listener will be removed. The same method is being used for rotation. Everything works almost perfect. I've set the project's target FPS to 100 and created a FPS counter. According to the FPS counter, the average FPS in firefox is around 100, while the top is 1000 and the bottom is 22. I think that the bottom and top FPSs are only happening during the initialization of the client (startup). The problem is that the ship appears to be almost perfectly smooth, while it should be just that without the "almost" part. It's almost as if the ship is "flickering" very very fast, you can't actually see it but it's hard to focus on the object while it's moving with your eyes. Also, every now and then, there seems to be a bit of a framerate spike, as if the client is skipping a couple of frames, you then see it quickly warp. It is very difficult to explain what the real problem is, but in general it's that the movement is not perfectly smooth. So, do you have any suggestions on how to make the movement or transition of objects perfectly smooth? Update 1: I re-created the client to demonstrate my problem. Please check it out. The client: http://feedpostal.com/test/MovementTest.html The Actionscript Project (full source): http://feedpostal.com/test/MovementTest.rar An example of a smooth flash game (not created by me): http://www.gamesforwork.com/games/swf/Mission%20Racing_august_10th_2009.swf It took me a pretty long time to recreate this client side version, I hope this will help with solving the problem. Please note: yes, it is actually pretty smooth. But it is definitely not smooth enough.

• SPP Socket createRfcommSocketToServiceRecord will not connect

  - by philDev

  Hello, I want to use Android 2.1 to connect to an external Bluetooth device, wich is offering an SPP port to me. In this case it is an external GPS unit. When I'm trying to connect I can't connect an established socket while being in the "client" mode. Then if I try to set up a socket (being in the server role), to RECEIVE text from my PC everything works just fine. The Computer can connect as the client to the Socket on the Phone via SPP using the SSP UUID or some random UUID. So the Problem is not that I'm using the wrong UUID. But the other way around (e.g. calling connect on the established client socket) createRfcommSocketToServiceRecord(UUID uuid)) just doesn't work. Sadly I don't have the time to inspect the problem further. It would be greate If somebody could point me the right way. In the following part of the Logfile has to be the Problem. Greets PhilDev P.S. I'm going to be present during the Office hours. Here the log file: 03-21 03:10:52.020: DEBUG/BluetoothSocket.cpp(4643): initSocketFromFdNative 03-21 03:10:52.025: DEBUG/BluetoothSocket(4643): connect 03-21 03:10:52.025: DEBUG/BluetoothSocket(4643): doSdp 03-21 03:10:52.050: DEBUG/ADAPTER(2132): create_device(01:00:00:7F:B5:B3) 03-21 03:10:52.050: DEBUG/ADAPTER(2132): adapter_create_device(01:00:00:7F:B5:B3) 03-21 03:10:52.055: DEBUG/DEVICE(2132): Creating device [address = 01:00:00:7F:B5:B3] /org/bluez/2132/hci0/dev_01_00_00_7F_B5_B3 [name = ] 03-21 03:10:52.055: DEBUG/DEVICE(2132): btd_device_ref(0x10c18): ref=1 03-21 03:10:52.065: INFO/BluetoothEventLoop.cpp(1914): event_filter: Received signal org.bluez.Adapter:DeviceCreated from /org/bluez/2132/hci0 03-21 03:10:52.065: INFO/BluetoothService.cpp(1914): ...

• Need help with fixing Genetic Algorithm that's not evolving correctly

  - by EnderMB

  I am working on a maze solving application that uses a Genetic Algorithm to evolve a set of genes (within Individuals) to evolve a Population of Individuals that power an Agent through a maze. The majority of the code used appears to be working fine but when the code runs it's not selecting the best Individual's to be in the new Population correctly. When I run the application it outputs the following: Total Fitness: 380.0 - Best Fitness: 11.0 Total Fitness: 406.0 - Best Fitness: 15.0 Total Fitness: 344.0 - Best Fitness: 12.0 Total Fitness: 373.0 - Best Fitness: 11.0 Total Fitness: 415.0 - Best Fitness: 12.0 Total Fitness: 359.0 - Best Fitness: 11.0 Total Fitness: 436.0 - Best Fitness: 13.0 Total Fitness: 390.0 - Best Fitness: 12.0 Total Fitness: 379.0 - Best Fitness: 15.0 Total Fitness: 370.0 - Best Fitness: 11.0 Total Fitness: 361.0 - Best Fitness: 11.0 Total Fitness: 413.0 - Best Fitness: 16.0 As you can clearly see the fitnesses are not improving and neither are the best fitnesses. The main code responsible for this problem is here, and I believe the problem to be within the main method, most likely where the selection methods are called: package GeneticAlgorithm; import GeneticAlgorithm.Individual.Action;

• Why is this RMagick call generating a segmentation fault?

  - by Grant Heaslip

  I've been banging my head against the wall for the better part of an hour trying to figure out what's going wrong here, and I'm sure (or rather hoping) it's something fairly obvious that I'm overlooking. I'm using Ruby 1.9.1, Sinatra 1.0, and RMagick 2.13.1. ImageMagick and RMagick are correctly installed and functional—I've successfully manipulated and saved images from irb. The relevant part of the params array (formatting changes for the sake of readability): {"admin_user_new_image_file"=> { :filename=>"freddie-on-shetland-pony.png", :type=>"image/png", :name=>"admin_user_new_image_file", :tempfile=>#<File:/var/folders/a7/a7pO5jMcGLCww9XBGRvWfE+++TI/-Tmp-/RackMultipart20100514-20700-o2tkqu-0>, :head=>"Content-Disposition: form-data; name=\"admin_user_new_image_file\"; filename=\"freddie-on-shetland-pony.png\"\r\nContent-Type: image/png\r\n" } } The relevant code: post "/admin/user/:account_name/image/new/" do if params[:admin_user_new_image_file][:tempfile] thumbnail = Magick::Image.read("png:"+params[:admin_user_new_image_file][:tempfile].path).first end end The error (line 229 is the line starting with "thumbnail = ": config.ru:229: [BUG] Segmentation fault ruby 1.9.1p376 (2009-12-07 revision 26041) [i386-darwin10.3.0] -- control frame ---------- c:0042 p:---- s:0196 b:0196 l:000195 d:000195 CFUNC

(In my case fts.h or ftw.h are not an option). I am using GLib as the data structures library. Still I have my doubts in regarding the way GLib is allocating, de-allocating memory ? When invoking g_slist_free(list) i also free the data contained by the elements ? Why all those memory leaks appear ? Is valgrind a suitable tool for profilinf memory issues when using a complex library like GLib ? LATER EDIT: If I g_slist_foreach(l,(GFunc)g_free,NULL);, the valgrind report is different, (All the memory leaks from 'definitely lost' will move to 'indirectly lost'). Still I don't see the point ? Aren't GLib collections implement a way to be freed ?

} @end Ignoring the fact that its really long I also tried to just set the property but then my product didnt have any values. So I alloc'd for all properties, not sure which is "correct" the use of product picker.h #import <UIKit/UIKit.h> @class Vehicle; @class Product; @interface Picker : UITableViewController <NSXMLParserDelegate> { NSString *currentRow; NSString *currentElement; Vehicle *vehicle; } @property (nonatomic, retain) NSMutableArray *dataArray; //@property (readwrite, copy) NSString *currentRow; //@property (readwrite, copy) NSString *currentElement; -(void) getYears:(NSString *)string; -(void) getMakes:(NSString *)year; -(void) getModels:(NSString *)year: (NSString *)make; -(void) getStyles:(NSString *)year: (NSString *)make: (NSString *)model; -(void) getHitch:(NSString *)year: (NSString *)make: (NSString *)model: (NSString *)style; -(void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName; -(void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string; -(void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict; @end The implementation .m #import "Product.h" #import "Picker.h" #import "KioskAppDelegate.h" #import "JSON.h" #import "Vehicle.h" @implementation Picker @synthesize dataArray; -(void) getHitch:(NSString *)year: (NSString *)make: (NSString *)model: (NSString *)style{ currentRow = [NSString stringWithString:@"z:row"]; currentElement = [NSString stringWithString:@"gethitch"]; //Reinitialize data array [self.dataArray removeAllObjects]; [self.dataArray release]; self.dataArray = [[NSArray alloc] initWithObjects:nil]; //Build url & string NSString *thisString = [[NSString alloc] initWithString:@""]; thisString = [NSString stringWithFormat:@"http://api.curthitch.biz/AJAX_CURT.aspx?action=GetHitch&dataType=json&year=%@&make=%@&model=%@&style=%@",year,make,model,style]; //Request NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:thisString]]; //Perform request and fill data with json NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; //Get string from data NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]; //set up parser SBJsonParser *parser = [[SBJsonParser alloc] init]; //parse json into object NSArray *tempArray = [parser objectWithString:json_string error:nil]; for (NSDictionary *dic in tempArray) { Product *tempProduct = [[Product alloc] initWithDict:dic]; NSLog(@"is tempProduct valid %@", (tempProduct) ? @"YES" : @"NO"); [self.dataArray addObject:tempProduct]; } } @end So I stripped out all the table methods and misc crap that doesnt matter. In the end my problem is adding the "tempProduct" object to the mutable array dataArray so that I can customize the table cells. Using the json framework im parsing out some json which returns an array of NSDictionary objects. Stepping through that my dictionary objects look good, I populate my custom object with properties for all my fields which goes through fine, and the values look right. However I cant add this to the array, I've tried several different implementations doesn't work. Not sure what I'm doing wrong. In some instances doing a po tempProduct prints the description and sometimes it does not. same with right clicking on the variable and choosing print description.

• Images missing after moving Django to new server

  - by miszczu

  I'm moving Django project to new server. I'm newbie in Django, and I don't know where should be upload folder. There are all images which should be displayed on website. In config file I haven't seen upload folder I could specify, so I'm guessing it always should be the same location for django projects or I just can't find it. Locations are saved in database. When I've put uploaded files into media folder, so url was like domain.co.uk/media/upload/media/images/year/month/day/image_name.ext and the same is on the old website, images on website ware still missing. All images are visible if I put url by hand, but django doesn't seems to see files. Also I check django log file: 2012-05-30 09:13:33,393 ERROR render: Thumbnail tag failed: [in /usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py (line 49)] Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py", line 45, in render return self._render(context) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py", line 97, in _render file_, geometry, **options File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/base.py", line 50, in get_thumbnail cached = default.kvstore.get(thumbnail) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/base.py", line 25, in get return self._get(image_file.key) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/base.py", line 123, in _get value = self._get_raw(add_prefix(key, identity)) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/cached_db_kvstore.py", line 26, in _get_raw value = KVStoreModel.objects.get(key=key).value File "/usr/lib/python2.6/site-packages/django/db/models/manager.py", line 132, in get return self.get_query_set().get(*args, **kwargs) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 344, in get num = len(clone) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 82, in __len__ self._result_cache = list(self.iterator()) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 273, in iterator for row in compiler.results_iter(): File "/usr/lib/python2.6/site-packages/django/db/models/sql/compiler.py", line 680, in results_iter for rows in self.execute_sql(MULTI): File "/usr/lib/python2.6/site-packages/django/db/models/sql/compiler.py", line 735, in execute_sql cursor.execute(sql, params) File "/usr/lib/python2.6/site-packages/django/db/backends/util.py", line 34, in execute return self.cursor.execute(sql, params) File "/usr/lib/python2.6/site-packages/django/db/backends/mysql/base.py", line 86, in execute return self.cursor.execute(query, args) File "/usr/lib64/python2.6/site-packages/MySQLdb/cursors.py", line 174, in execute self.errorhandler(self, exc, value) File "/usr/lib64/python2.6/site-packages/MySQLdb/connections.py", line 36, in defaulterrorhandler raise errorclass, errorvalue DatabaseError: (1146, "Table 'thumbnail_kvstore' doesn't exist") 2012-05-30 09:13:33,396 DEBUG execute: (0.000) SELECT `freetext_freetext`.`id`, `freetext_freetext`.`key`, `freetext_freetext`.`content`, `freetext_freetext`.`active` FROM `freetext_freetext` WHERE (`freetext_freetext`.`active` = True AND `freetext_freetext`.`key` = office-closed-message ); args=(True, u'office-closed-message') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,399 DEBUG execute: (0.000) SELECT `menus_menu`.`id`, `menus_menu`.`name`, `menus_menu`.`slug`, `menus_menu`.`base_url`, `menus_menu`.`description`, `menus_menu`.`enabled` FROM `menus_menu` WHERE (`menus_menu`.`enabled` = True AND `menus_menu`.`slug` = about ); args=(True, u'about') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,401 DEBUG execute: (0.000) SELECT `menus_menuitem`.`id`, `menus_menuitem`.`menu_id`, `menus_menuitem`.`title`, `menus_menuitem`.`url`, `menus_menuitem`.`order` FROM `menus_menuitem` INNER JOIN `menus_menu` ON (`menus_menuitem`.`menu_id` = `menus_menu`.`id`) WHERE `menus_menu`.`slug` = about ORDER BY `menus_menuitem`.`order` ASC; args=(u'about',) [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,404 DEBUG execute: (0.000) SELECT `freetext_freetext`.`id`, `freetext_freetext`.`key`, `freetext_freetext`.`content`, `freetext_freetext`.`active` FROM `freetext_freetext` WHERE (`freetext_freetext`.`active` = True AND `freetext_freetext`.`key` = contactdetails-footer ); args=(True, u'contactdetails-footer') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] I checked database and there is no table calls thumbnail_kvstore, but I have database backup, and in backup files this table doesn't exist.

• Jquery Flexslider - can't see navigational images (manualControl)

  - by Kim Thomas

  I've spent a lot of time looking at the post on 3/13/12 re: manual controls, but isn't getting me all the way there...probably because I don't know jquery. Sorry, newbie on board. I'm trying to get the right/left arrows to show, as well as the 1, 2, 3...at the bottom. They are there, I see the lists on Firebug, just don't know how to add them to the "hook" (?) so they appear.

• NSOperationQueue bug with dependencies

  - by Daniel

  I am using NSOperation and NSOperationQueue for performing a sequence of operations, all dependent on each other (2 on 1, 3 on 2, etc...). I set the dependency after I create the operations. I am encountering problems when the queue completes: the program crashes in the _release part of the code, apparently when the NSOperations are getting released. Note that they all get released at the end by the queue, because it is only after the very last one which depends on the second last one, which depends on etc... that they can be released. If I remove any dependency, the code runs fine. If I change waitUntilFinished: to NO, it crashes, if it is YES, it does not. I have isolated the problem to the following code which does not use any of my custom classes. NSOperation by default is a class that does absolutely nothing. Yet, this still crashes when all operations have completed. Therefore, it appears I am not using NSOperationQueue properly but can't see what is wrong. I am running on 10.9 and I have noticed that in general Maverick 10.9 is much more sensitive to these issues than 10.8. I call this method from the main Thread with a Menu item: - (void) testOperations:(id)object { NSOperationQueue* queue = [ [ NSOperationQueue alloc ] init ]; NSMutableArray* array = [ NSMutableArray array ]; for ( int i = 0; i < 10000; i++) [ array addObject: [[[ NSOperation alloc ] init ] autorelease ] ]; for ( int i = 1; i < [ array count ]; i++) [[ array objectAtIndex:i ] addDependency:[array objectAtIndex:i-1]]; // remove this and no crash [ queue addOperations: array waitUntilFinished:NO ]; // Change to YES, no crash [ queue autorelease ]; // or release, it does not make a difference, in fact leaking the memory makes no difference: the code crashes when the queue is removing the NSOperations } This will crash every single time with: bool objc::DenseMapBase , objc_object*, unsigned long, objc::DenseMapInfo, true: (EXC_BAD_ACCESS) The full stack is: #0 0x9104d81b in objc::DenseMapBase<objc::DenseMap<objc_object*, unsigned long, true, objc::DenseMapInfo<objc_object*> >,

• Updating the value of a math equation with YUI slider and simple radio buttons.

  - by dj lewis

  I have a form that is used to show a price for a product. I have a YUI slider setup that changes the price, and it works perfectly. Now I'm trying to add in radio buttons that also should update that same price value. The price displayed should take into account all 3 fields, and update dynamically as any are updated.

• XSLT 1.0 help with recursion logic

  - by DashaLuna

  Hello guys, I'm having troubles with the logic and would apprecite any help/tips. I have <Deposits> elements and <Receipts> elements. However there isn't any identification what receipt was paid toward what deposit. I am trying to update the <Deposits> elements with the following attributes: @DueAmont - the amount that is still due to pay @Status - whether it's paid, outstanding (partly paid) or due @ReceiptDate - the latest receipt's date that was paid towards this deposit Every deposit could be paid with one or more receipts. It also could happen, that 1 receipt could cover one or more deposits. For example. If there are 3 deposits: 500 100 450 That are paid with the following receipts: 200 100 250 I want to get the following info: Deposit 1 is fully paid (status=paid, dueAmount=0, receiptNum=3. Deposit 2 is partly paid (status=outstanding, dueAmount=50, receiptNum=3. Deposit 3 is not paid (status=due, dueAmount=450, receiptNum=NAN. I've added comments in the code explaining what I'm trying to do. I am staring at this code for the 3rd day now non stop - can't see what I'm doing wrong. Please could anyone help me with it? :) Thanks!

• jQuery Datatables throws error when dynamically created row headers

  - by JM4

  I am using the Datatables jquery plugin for one of my projects. For one in particular, the number of columns can vary based on how many children a consumer has (yes I realize normalization and proper technique would insert on another row but it is a client requirement). Datatables must be set up as such: <table> <thead> <tr> <th></th> </tr> </thead> <tbody> <tr> <td></td> </tr> </tbody> </table> my script starts out as: <table cellpadding="0" cellspacing="0" border="0" class="display" id="sortable"> <thead> <tr> <th>parent name</th> <th>parent phone</th> <?php try { $db->beginTransaction(); $stmt = $db->prepare("SELECT max(num_deps) FROM (SELECT count(a.id) as num_deps FROM children a INNER JOIN parents b USING(id) WHERE a.id !=0 GROUP BY a.id) x"); $stmt->execute(); $rows = $stmt->fetchAll(); for($i=1; $i<=$rows[0][0]; $i++) { echo " <th>Child Name ".$i."</th> <th>Date of Birth ".$i."</th> "; } $db->commit(); } catch (PDOException $e) { echo "<p align='center'>There was a system error. Please contact administration.<br>".$e->getMessage()."</p><br />"; } ?> </tr> </thead> In this manner, the final column headers can be 1 or 50 spots long. However, with this dynamic code in place, datatables throws the following error: ""DataTables warning (table id = 'datatable'): Cannot reinitialise DataTable. To retrieve the DataTables object for this table, please pass either no arguments to the dataTable() function, or set bRetrive to true. Alternativly, to destroy old table and create a new one...ETC."' Yes I have set "bRetrieve" : true in the javascript above and that does not do the trick. If I remove the code above, the file "works" fine but it leaves off the necessary columns for my table. Any ideas?

UPDATE REGARDING COMMENTS/ANSWERS I have received a number of responses indicating the number of headers may not match the field count in the body. As I mention below, eliminating the php script below altogether would eliminate 5+ fields in the header and without question throw the count match off balance. This DOES NOT however cause an error and in fact "resolves" the issue in that datatables functions properly (even though there is NO header record for 5+ fields in the body.

• Signal "0" error while scrolling a tableview with images

  - by Amitkumar

  Hi, I have a problem while scrolling images on tableview. I am getting a Signal "0" error. I think it is due to some memory issues but I am not able to find out the exact error. The code is as follows, - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [travelSummeryPhotosTable dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]autorelease]; } //Photo ImageView UIImageView *photoTag = [[UIImageView alloc] initWithFrame:CGRectMake(5.0, 5.0, 85.0, 85.0)]; NSString *rowPath =[[imagePathsDictionary valueForKey:[summaryTableViewDataArray objectAtIndex:indexPath.section]] objectAtIndex:indexPath.row]; photoTag.image = [UIImage imageWithContentsOfFile:rowPath]; [cell.contentView addSubview:photoTag]; [photoTag release]; // Image Caption UILabel *labelImageCaption = [[UILabel alloc] initWithFrame:CGRectMake(110.0, 15.0, 190.0, 50.0)]; labelImageCaption.textAlignment = UITextAlignmentLeft; NSString *imageCaptionText =[ [imageCaptionsDictionary valueForKey:[summaryTableViewDataArray objectAtIndex:indexPath.section]] objectAtIndex:indexPath.row]; labelImageCaption.text = imageCaptionText; [cell.contentView addSubview:labelImageCaption]; [labelImageCaption release]; return cell; } Thanks in advance.
