• Static pages for large photo album

  - by Phil P

  I'm looking for advice on software for managing a largish photo album for a website. 2000+ pictures, one-time drop (probably). I normally use MarginalHack's album, which does what I want: pre-generate thumbnails and HTML for the pictures, so I can serve without needing a dynamic run-time, so there's less attack surface to worry about. However, it doesn't handle pagination or the like, so it's unwieldy for this case. This is a one-time drop for pictures from a wedding, with a shared usercode/password for distribution to the guests; I don't wish to put the pictures in a third-party hosting environment. I don't wish to use PHP, simply because that's another run-time to worry about, I might relent and use something dynamic if it's Python or Perl based (as I can maintain things written in those). I currently have: Apache serving static files, Album-generated, some sub-directories to divide up the content to be a little more manageable. Something like Album but with pagination already handled would be great, but I'm willing to have something a little more dynamic, if it lets people comment or caption and store the extra data in something like an sqlite DB. I'd want something light-weight, not a full-blown CMS with security updates every three months. I don't want to upload pictures of other peoples' children into a third-party free service where I don't know what the revenue model is. (For my site: revenue is none, costs out of pocket). Existing server hosting is *nix, Apache, some WSGI. Client-side I have MacOS. Any advice?

• Proper method to update and draw from game loop?

  - by Lost_Soul

  Recently I've took up the challenge for myself to create a basic 2d side scrolling monster truck game for my little brother. Which seems easy enough in theory. After working with XNA it seems strange jumping into Java (which is what I plan to program it in). Inside my game class I created a private class called GameLoop that extends from Runnable, then in the overridden run() method I made a while loop that handles time and such and I implemented a targetFPS for drawing as well. The loop looks like this: @Override public void run() { long fpsTime = 0; gameStart = System.currentTimeMillis(); lastTime = System.currentTimeMillis(); while(game.isGameRunning()) { currentTime = System.currentTimeMillis(); long ellapsedTime = currentTime - lastTime; if(mouseState.leftIsDown) { que.add(new Dot(mouseState.getPosition())); } entities.addAll(que); game.updateGame(ellapsedTime); fpsTime += ellapsedTime; if(fpsTime >= (1000 / targetedFPS)) { game.drawGame(ellapsedTime); } lastTime = currentTime; } The problem I've ran into is adding of entities after a click. I made a class that has another private class that extends MouseListener and MouseMotionListener then on changes I have it set a few booleans to tell me if the mouse is pressed or not which seems to work great but when I add the entity it throws a CME (Concurrent Modification Exception) sometimes. I have all the entities stored in a LinkedList so later I tried adding a que linkedlist where I later add the que to the normal list in the update loop. I think this would work fine if it was just the update method in the gameloop but with the repaint() method (called inside game.drawGame() method) it throws the CME. The only other thing is that I'm currently drawing directly from the overridden paintComponent() method in a custom class that extends JPanel. Maybe there is a better way to go about this? As well as fix my CME? Thanks in advance!!!

• LAMP setup - phpmyadmin says the mysqli extension is missing (but its listed in phpinfo)

  - by WebweaverD

  I regularly set up virtualbox ubuntu setups to run as local webservers. I have set these up several times and never had an issue. Recently I have been cloning them but wanted to do a fresh install this time in the hopes of fixing some niggling problems which have propagated through my setups. However, something has changed: 1)vb guest additions no longer allow me to copy and paste (i'll worry about that later) 2)more importantly phpmyadmin no longer works as installed - Initially going to localhost/phpmyadmin gave a message that the page could not be found. So I have followed some instructions (sorry I know its vague I cant find them now) which have created a phpmyadmin directory in /var/www but now I get an error saying: the mysqli extension is missing. If I run phpinfo mysql and mysqli are listed. All I have done so far is install apache2 (working) install php5 (which I think used to come with apache) Install mysql server (and client for good measure) and install phpmyadmin I found a post of a similar question which suggested I should install php5-mysql (done) and edit php.ini and uncomment the line extension-mysqli.so - this is not there, so I tried adding it with no joy. I have restarted apache and still no joy on phpmyadmin. Any help is much appreciated as this is driving me nuts. Why the change for the worse - I was just starting to like linux! I'm running a windows 7 machine and the guest os is ubuntu 12.04 - I ran apt-get update before doing anything so all packages should be the latest versions.

• Sub-systems in game engines

  - by Hillel

  So here's the problem- I'm writing my own engine library, and it works fine with stuff like menus and the actual game screen. The thing is, I can't really figure out how to integrate something like an intro or dialogue preceding certain levels into this system. Let's look at another example- say I have a game-specific engine which gets a Level object and runs it. Engine would have its own collision and physics system, all hard coded. Now, what if at some point in a level, I want the player to enter a mini-game with different rules? How do I morph the Engine class to support these sub-systems without having to deal with their code all the time (as in: if(regular game) ... else if(mini game) ...)? And what if I want an intro animation at the start of a level, and I want the player to be able to assume control of his character once the animation ends, do I implement the animation into the Engine class itself? Or maybe I need to run another class, CutScene, and when it ends, it calls Engine and starts the level? What if I want to add a dialogue system, where at the start of each level there's a short dialogue and the player can't control his character, and once it ends, he can? Would I then run the dialogue code inside the Engine code? Maybe these sub-systems should all be scripted? I don't know anything about scripting, is it necessary for this kind of situation? Any help would be appreciated.

• How to disable discrete GPU using NVIDIA drivers?

  - by penzoiders

  I have a DELL studio XPS 13 (aka 1340) as of 12.04 most things run smoothly out of the box, but I have some power draining and warmness issues (if not to be called terrible heat issues) The system came with a NVIDIA GeForce 9500M (which has Hybrid SLI) and it shows up in "lspci" as these 2 cards 02:00.0 VGA compatible controller: NVIDIA Corporation G98 [GeForce 9200M GS] (rev a1) 03:00.0 VGA compatible controller: NVIDIA Corporation C79 [GeForce 9400M G] (rev b1) I had to install nvidia-current over noveau driver 'cause noveau does freeze the system after suspension. By installing nvidia-current and running nvidia-xconfig the resume process after suspension is fixed. By the way both with nvidia-current and noveau the system drains a lot of battery and heats up a lot. I suppose this is because the discrete GPU is always on. I don't really need 3D graphics on this system, if not the minimal to run unity and compiz for window management. So my question is: How do I disable, using nvidia-current, the discrete GPU 9200M and use only the integrated one 9400M? notes: In BIOS I have no option to disable discrete GPU This I think is not applicable because of the suspension-freeze issue (with noveau): https://help.ubuntu.com/community/HybridGraphics I've found this but I don't know which --sli option I should choose to fit my needs: http://manpages.ubuntu.com/manpages/hardy/man1/nvidia-xconfig.1.html My system has not optimus or cuda, but anyone can tell me if bumblebee can work for me?

• How to optimize a box2d simulation in action game?

  - by nathan

  I'm working on an action game and i use box2d for physics. The game use a tiled map. I have different types of body: Static ones used for tiles Dynamic ones for player and enemies Actually i tested my game with ~150 bodies and i have a 60fps constantly on my computer but not on my mobile (android). The FPS drop as the number of body increase. After having profiled the android application, i saw that the World.step took around 8ms in CPU time to execute. Here are few things to note: Not all the world is visible on screen, i use a scrolling system Enemies are constantly moving toward the player so there is alaways to force applied to their body Enemies need to collide between each others Enemies collide with tiles I also now that i can active/desactive or sleep/awake bodies. Considering the fact that only a part of the enemies are possibly displayed on screen, is there any optimizations i can do to reduce the execution time of box2d simulation? I found a guy trying an optimization based on distance of enemies from the player (link). But i seems like he just desactives far bodies (in my case, i could desactive bodies that are not visible). But my enemies need to move even when they are not visible on screen, and applying forces will not workd on inactive bodies. Should i play with sleeping bodies here? Also, enemies are composed by two fixtures and are constantly colliding with each others and with tiles but i really never need to get notified about that. Is there anything i can do to optimize this kind of scenario? Finally, am i wrong to try to run simulation at 60FPS on mobile and should i try to make it run at 30FPS?

• How do I develop database-utilizing application in an agile/test-driven-development way?

  - by user39019

  I want to add databases (traditional client/server RDBMS's like Mysql/Postgresql as opposed to NoSQL, or embedded databases) to my toolbox as a developer. I've been using SQLite for simpler projects with only 1 client, but now I want to do more complicated things (ie, db-backed web development). I usually like following agile and/or test-driven-development principles. I generally code in Perl or Python. Questions: How do I test my code such that each run of the test suite starts with a 'pristine' state? Do I run a separate instance of the database server every test? Do I use a temporary database? How do I design my tables/schema so that it is flexible with respect to changing requirements? Do I start with an ORM for my language? Or do I stick to manually coding SQL? One thing I don't find appealing is having to change more than one thing (say, the CREATE TABLE statement and associated crud statements) for one change, b/c that's error prone. On the other hand, I expect ORM's to be a low slower and harder to debug than raw SQL. What is the general strategy for migrating data between one version of the program and a newer one? Do I carefully write ALTER TABLE statements between each version, or do I dump the data and import fresh in the new version?

• Setting console resolution in Ubuntu Server 13.10 within VMware

  - by user205625

  I've completed an install of Ubuntu Server 13.10 within VMware and am running into a problem configuring the console (non-graphical) resolution. When I was running Ubuntu Server 13.04, I ran into the same problem... posted the question here, which I later solved by editing /etc/default/grub thus: GRUB_CMDLINE_LINUX_DEFAULT="splash vga=789" I then ran sudo update-grub, sudo reboot and 13.04 stuck in a larger-size console mode... just what I wanted. BUT when I run the same commands in 13.10, during the reboot it changes to the new screen-res, BUT the screen stays black and I can't interact with it. I power down the VM, go back to a previous snapshot, and try again... and again. Since the hwinfo package is no longer available, I can't run sudo hwinfo --framebuffer to see what options are available. Ideas anyone? Here are the uncommented settings in my /etc/default/grub file at this moment: GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=false GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian GRUB_CMDLINE_LINUX_DEFAULT="splash" GRUB_CMDLINE_LINUX="find_preseed=/preseed.cfg" GRUB_DISABLE_LINUX_RECOVERY=false GRUB_GFXMODE=800x600

• How can I get a gnome environment in my VNC session?

  - by adante

  When I start VNC I have an empty desktop without the ability to manage windows or start apps etc). I'd like to have a desktop environment to be able to basic desktop things (someone asked me why I wanted this - I can't really say except that I would like my computer to be useful). My focus at the moment is basically having a working environment with as little time/effort expenditure as possible, as opposed to spending a full-time week learning the most trivial and arcane details of x, vnc, gnome or whatever passes for the current desktop architecture standard of the hour. What command or series of hoops do I have to jump to to achieve this? I have tried running gnome-session but it looks like it is attempting to run compiz and fails spectacularly. I've also tried running metacity but this simply gives me a titlebars to my windows (this is great! But I'd also like the taskbar and other stuff). I considered trying to start gnome-session in a way that it uses metacity instead of compiz. But I don't know how to do this. Tutorials on the net exist for changing to metacity - once you already have compiz running. Not so useful if compiz does not run.

• Ubuntu boots in read-only filesystem after upgrade!

  - by akatzbreaker

  I got a serious problem here: I recently upgraded to the Latest Version of Ubuntu. Now, I boot to my Ubuntu Partition, and I get a Low-Graphics error! I boot to a Recovery-Mode to see what the Problem is. Then, I try to Fix any Damaged Packages, to run fsck but nothing solved the Problem. Then, from the Recovery Menu, I open a Root Shell. I try to create a File and I understand that the Filesystem is Read-Only. Then, I run: mount -o remount,rw / and it Worked for that Terminal Session! When I go back to recovery, I select to resume Boot Normally but I get the Same Error! a I also tried to Boot to my Root Shell again, remount as Read-Write and Start Gnome from there. It Worked! (But the user is ROOT, and is quite Dangerous!) However, I can't do all this proccess at every boot! Any Solution? (Note that when I try to create a new File in my Ubuntu Partition from another OS, I don't get any Errors!)

• Acer Aspire One 725 - missing graphic card driver for Radeon HD 6290?

  - by Melon

  Recently I bought an Acer Aspire One 725 Netbook and installed Ubuntu 12.10 on it. I bought it, because it can run HD movies and has Full HD on external VGA port. However, movies from youtube have a really slow framerate. If you open three tabs in Opera (for example g-mail, youtube and askubuntu) it gets really laggy. My suspicion is that the driver for graphic card is missing. When I check the System->Details->Graphics the driver is unknown. After running lspci | grep VGA I get this output: 00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Device 980a From what I see, I have a AMD C70 processor integrated with (or something similar) AMD Radeon HD 6290. Has anyone had the same problem? Do you know which drivers need to be installed for the graphics to work properly? On official Acer page there are only drivers for Win7 and Win8... Update: I have tried installing fglrx but I get the following error (either I don't have libraries or someone didn't make a clean build before release ;) /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c: In function ‘KCL_MEM_AllocLinearAddrInterval’: /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:2124:5: error: implicit declaration of function ‘do_mmap’ [-Werror=implicit-function-declaration] /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:2124:13: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c: In function ‘kasInitExecutionLevels’: /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:4159:5: error: ‘cpu_possible_map’ undeclared (first use in this function) /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:4159:5: note: each undeclared identifier is reported only once for each function it appears in /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:4159:5: warning: left-hand operand of comma expression has no effect [-Wunused-value] Update 2: After fixing the erros in compilation, ubuntu acts bizarre and unstable (no left icon panel, no upper panel, cannot run any programs, I only see desktop)

• Javascript is not loading

  - by Oden

  Hey, I've got a problem with JavaScript under Ubuntu, that drives me crazy. I'm using Gedit for my web sites since I'm an Ubuntu user. When I start a new website I create (usually with the gnome terminal) folder structure, and I copy the files I need into them. The next step is creating an index.html where I build the design and basic JavaScript functionality. JavaScript is stored in a sub-folder of the project and when i try to load one using the tag in the header, my whole page body disappears. If the source contains a script tag with its own body, and its not the first its code wont run. I've tried to solve the problem by setting chmod to 777 with sudo chmod -R 777 . but nothing changed. CSS is loading correctly, but JS isn't. I'm using the newest version of apache, no mod_rewrite stuff, but i get the same problem when I run the html from file (file:///...) Do anyone know how to solve this problem?

• How do I list all the relation variables and debug them interactively?

  - by mfisch

  I'm writing a charm that requires a mysql database, I found from looking at other charms that this (below) is how I get the info about the database: user=`relation-get user` password=`relation-get password` mysqlhost=`relation-get private-address` But I just found that from reading the wordpress charm example, is there a way to show all the relation variables that I can use? Also, while debugging my db-relation-changed script, I wanted to ssh into my host and interactively run those commands, for example relation-get user, but it didn't work. I resorted to having to restart everything and use juju log to print them out. This wasted a lot of time. Is there a way to print out these relations, either from my dev box or from the instance running my charm? (Below is what happens when I tried to interactively run relation-get): ubuntu@mfisch-local-tracks-0:~$ relation-get user usage: relation-get [-h] [-o OUTPUT] [-s SOCKET] [--client-id CLIENT_ID] [--format FORMAT] [--log-file FILE] [--log-level CRITICAL|DEBUG|INFO|ERROR|WARNING] [-r RELATION ID] [settings_name] [unit_name] No JUJU_AGENT_SOCKET/-s option found I tried juju debug-hooks tracks/0 -e local, that dropped me into a shell and relation-get still failed.

  I know file permissions have been covered on here before, but im struggling to get my head around the concept for my scenario. I created the files on an old ubuntu installation. Ive copied the files into my new ubuntu installation and put them in my webroot. When i attempt to run the files (theyre PHP files) i get an error relating to permissions in an attempt to fix this, i assumed that they must still be owned by the previous owner, so i ran chown -R on the directory, with my username as an argument, in order to take ownership of all of the files in the directory. It should be noted that the usernames between new and old ubuntu installations were the same. When i attempt to run the files again, same problem: 500 error due to permissions problems. Can anyone tell me what other steps i should take? The webroot for my apache installation is inside my home folder. If i create new files in my webroot, they also work as expected, its only the old files that are causing the problem.

• C++ program...overshoots? [migrated]

  - by Zdrok

  I'm decent at C++, but I may have missed some nuance that applies here. Or maybe I completely missed a giant concept, I have no idea. My program was instantly crashing ("blah.exe is not responding") about 1/5 times it was run (other times it ran completely fine) and I tracked the problem down to a constructor for a world class that was called once in the beginning of the main function. Here is the code (in the constructor) that causes the problem: int ii; for(ii=0;ii<=255;ii++) { cout<<"ent "<<ii<<endl; entity_list[ii]=NULL; } for(ii=0;ii<=255;ii++) { cout<<"sec "<<ii<<endl; sector_list[ii]=NULL; } entity_list[0] = new Entity(0,0); entity_list[0]->_world = this; Specifically the second for loop. The cout references are new for the sake of telling where it is having trouble. It would print the entire "ent 1" to "ent 255" and then "sec 1" to "sec 255" and then crash right after, as if it was going for a 257th run through of the second for loop. I set the second for loop to go until "ii<=254" which stopped all crashes. Does C++ code tend to "overshoot" for loops or something? What is causing it to crash at this specific loop seemingly at random? By the way, entity_list and sector_list point to classes called Entity and Sector, respectively, but they are not constructing anything so I didn't think it would be relevant. I also have a forward declaration for the Entity class in a header for this, but since none were being constructed I didn't think it was relevant either. EDIT: It was due to the new Entity line, I assumed wrongly that the fact that altering the for statement to 254 fixed the crashes meant that it had to be there. I still don't understand why the for loop is related, though.

• How to troubleshoot GPU freezes?

  - by dlsmith2

  So in advance I'll just say I am a total linux newbie, so be kind. I just downloaded Ubuntu 11.10 and this is my first experience with Linux. I enjoy it so far and actually enjoy it except for when my computer freezes. This has been quite often so far. I've done a little research and it seems my problem is with the GPU. When it does freeze I can move the cursor but cannot click on anything. I also cannot run Alt+F2 xkill. So my only previous experience has been with Windows and I would normally solve an issue like this with Ctrl+Alt+Delete and just shut down the offending program. I do not know how to do this in Ubuntu and not even sure this would even work. Please help me if you can, how do I deal with a freeze without having to resort to a hard shutdown, I cannot seem to run the computer over one hour without experiencing this issue. I tried accessing my GRUB menu on startup but I can't even seem to do that. Also the only real program I have been running whenever this happens seems to be Firefox. Thank you, appreciate any help. After running lspci | grep VGA command prompt: 00:12.0 VGA compatible controller: nVidia Corporation C67 [GeForce 7150M / nForce 630M] (rev a2)*****

• How do I bridge my wireless to my wired connection?

  - by gatoatigrado

  I want to bridge the wireless connection with the wired connection. The wireless is the host and the wired is the client, so to speak. Internet sharing (inet <--> wifi <--> ethernet) I tried to bridge my ethernet connection by going to network manager edit connections wired edit IPv4 settings shared to other computers Screenshots However, it seems to automatically disconnect half a second after it says "connection established"! edit 2 got the network manager logs, it seems the address is in use. See http://pastebin.com/DjqRshxW , line 45. nm-tool output is here: http://pastebin.com/x5Aci5V1 . I tried firestarter, as mentioned in another thread, and no luck. I don't have time to bother with a dozen command line tricks, unless is copy & pasting a shell script... so please suggest ways that use GUIs and/or won't leave my computer in a confused state (e.g. disabling network manager, manually connecting to a WPA network, installing brutils, etc.). edit: one idea that would work, if it's possible -- is there a way to share connections via SSH and SOCKS5? I'd need to do this at a system-wide level though; I only know how to do it through the browser now. Then, I could run ifconfig eth0 192.168.4.1 on the computer sharing the inet, and ifconfig eth0 192.168.4.2 on the computer I'm trying to share with; I know this does work for host-to-host transfers. edit 3 If I run sudo killall dnsmasq, then nothing is using the 10.42.43.1 address the network manager sharing wants to use. But now it just takes longer to die, with error "NetworkManager[5935]: dnsmasq died with signal 9" [ http://pastebin.com/4FNtpugi ]. Looking at just the commands [ http://pastebin.com/1vrtQeWk ], maybe it's trying to route eth0 to itself? I'm not that familiar with networking things though.

• Developing with Oracle ADF Mobile and ADF Business Components Backend

  - by Shay Shmeltzer

  It's great to finally have the Oracle ADF Mobile solution out there. If you are not familiar with ADF Mobile - it basically lets you build applications that run on iOS and Android devices using the concepts you already know - components based UI constructions (same idea as JSF), taskflows, data controls, Java and of course JDeveloper. I created one demo that shows how to build an on-device application that gets data from local Java files (that run on the device - yes we do Java on iOS too) - you can see it here. However, one thing many of you might be wondering is how can you get data from your database into these mobile applications. Well if you already built your data access with Oracle ADF Business Components then here is a two step video demo that shows you what to do. The steps are: 1. Expose ADF Business Components as Services 2. Create an ADF Mobile application that consumes the above services with the Web service data control Simple right? That's the whole point of ADF Mobile - making on device application development as simple as possible. Try it out on your device.

• TFS API The All New Team Project Picker &ndash; Beautiful!

  - by Tarun Arora

  The Team Project Picker in TFS 2011 looks gorgeous. I specially like the status bar on the working state, at least let’s you know that the project picker is still working on getting the details and of course the new icons for team project collection and team projects are stunning too.     How do I get the Team Project Picker using the TFS API? That is fairly straight forward. Add a reference to the Microsoft.TeamFoundation.Client dll available in C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\ReferenceAssemblies\v2.0 and use the below code, public void ConnectToTfs() { TeamProjectPicker tfsPP = new TeamProjectPicker(TeamProjectPickerMode.MultiProject, false, new UICredentialsProvider()); tfsPP.ShowDialog(); }   Download a sample application here Why does my project picker look different? You might run into an issue, where the project picker looks like the below, When the Team Project Picker is run from inside of VS the colour theme will be picked up from VS itself. When running outside of VS the windows theme colours are used, so there can be differences between the two. Currently there isn’t a way to change that since the dialog itself is not public (just the wrapper that launches the dialog). So don’t be surprised if the Team Project Picker looks different then expected :-]
