• Automatic syncing USB HD drive to local HD (different computers)

  - by luri

  I have a desktop PC at work, and a laptop at home.... or elsewhere. What I want to do is use a USB HD to store my documents (about 130 Gb, maybe more). That would serve as backup and also port my files to my laptop. I'd like any of both computers to automatically sync all files there with local copies, so that I can work at either of them and keep updated copies of everything in both (plus the USB drive, which would allow me to work in other computers, too, apart from being another backup). Dropbox ins't a solution for me, due to pricing and 100Gb limit. The workflow would be as follows, to clear things up: I work on PC1. Changes in files are automatically synced to USB whenever a file is modified. I go home and boot PC2. I plug the usb drive and local files are synced (if changed) with the most recent usb copies. While I work at PC2, again, changes in files spread to my USB drive. Whenever I go to PC1 again, I plug my usb and again everything synces. So the questions would be: a) Am I crazy? b) Can it be done? c) Will I have any file conflicts (provided I'm the only one that will modify the files)?

• How to convince a client to switch to a framework *now*; also examples of great, large-scale php applications.

  - by cbrandolino

  Hi everybody. I'm about to start working on a very ambitious project that, in my opinion, has some great potential for what concerns the basic concept and the implementation ideas (implementation as in how this ideas will be implemented, not as in programming). The state of the code right now is unluckily subpar. It's vanilla php, no framework, no separation between application and visualization logic. It's been done mostly by amateur students (I know great amateur/student programmers, don't get me wrong: this was not the case though). The clients are really great, and they know the system won't scale and needs a redesign. The problem is, they would like to launch a beta ASAP and then think of rebuilding. Since just the basic functionalities are present now, I suggested it would be a great idea if we (we're a three-people shop, all very proficient) ported that code to some framework (we like CodeIgniter) before launching. We would reasonably be able to do that in < 10 days. Problem is, they don't think php would be a valid long-term solution anyway, so they would prefer to just let it be and fix the bugs for now (there's quite a bit) and then directly switch to some ruby/python based system. Porting to CI now will make future improvements incredibly easier, the current code more secure, changing the style - still being discussed with the designers - a breeze (reminder: there are database calls in template files right now); the biggest obstacle is the lack of trust in php as a valid, scalable technology. So well, I need some examples of great php applications (apart from facebook) and some suggestions on how to try to convince them to port soon. Again, they're great people - it's not like they would like ruby cause it's so hot right now; they just don't trust php since us cool programmers like bashing it, I suppose, but I'm sure going on like this for even one more day would be a mistake. Also, we have some weight in the decision process.

• Ubuntu 12.04 desktop, VNC viewer not refreshing screen

  - by user73279

  I've had this issues across multiple machines and multiple versions of Ubuntu desktop (all 10.04 or later). Usually it happens with an old laptop I've put Ubuntu on but now it's happening on my primary dev machine (a quad-core PC recently upgraded to Ubuntu 12.04 desktop). The problem is this - I can connect to the machine and login with the password, the initial screen looks fine but never refreshes. I can see the monitor for the machine across the room and can see the mouse move and the menus pop up but the image of the screen on the PC in front me running the VNC viewer never updates. So the mouse and keyboard commands are working. Ubuntu 12.04 Desktop Ultra VNC Viewer (also seen with RealVNC's free VNC viewer) Desktop Sharing Static IP on eth0; Dynamic ID on eth1 I think it is an Ubuntu config issue because this PC used to work just fine with 9.04, 10.04, and 11.10 (over the past couple of years). I've also had a couple of laptops that used to have this issue with older Ubuntu's but don't with 12.04. Additional info: The Win7 PC I'm trying to use to control the Ubuntu PC is connected via 2 DLink 8-port gigabit routers. The Ubuntu laptop I usually control via VNC is typically only connected to the network via wireless. The screen refresh is choppy but usable. I've repeated the issue on a Win7 laptop which was connected via ethernet and wireless.

• What are all the components of a "Facebook App"?

  - by pnongrata

  I am a developer who has never personally partaken in social media (in any form) for reasons completely outside the scope of this question. I am "off the grid" (no Facebook, Twitter, etc accounts). I'm currently building a web app and would like the app to have a presence on Facebook, and possibly even "port" my app over as a Facebook app. My understanding of Facebook Apps is that they're just normal web apps that get <iframe>d into a Facebook page. The app is actually hosted on your server (not FB's servers). But this got me thinking: Don't Facebook Apps have "profile pages"? Is there anything developers can do to customize the behavior of their own profile pages? Do apps have the ability to do things like MySpace themes used to do (i.e., customize and interact with User profile pages, Groups, etc.)? Do Facebook Apps gain any sort of extra capabilities (inside of Facebook) that a normal web app would not have? It seems to me like if all a Facebook App is, is an iframed-web app, that it would still need to communicate with Facebook via its many APIs, just like a normal app would have to, right? If it's not possible to write an app that can customize the UI or behavior of user profiles and other pages, then how do games like "Farmville" interact with User profiles so that you see updates to profiles like "John Smith reached level 2 of Farmville"? Basically, I'm asking any battle-worn Facebook app developers if my understanding of Facebook Apps is correct, or if I'm missing anything big here. It's my understanding that for security reasons (obviously) Facebook doesn't allow apps to customize anything outside of the iframe it lives in. So if I want my app to appear like it's "interacting" with its Facebook users, it looks like I just need to publish stuff to the users' news feeds to try and encourage people to use my app (please correct me if I'm wrong here!). Thanks in advance for any corrections, clarifications, advice or suggestions!

• Latest update to Ubuntu 13.10 broke Intel graphics drivers

  - by James Davies

  I'm running a copy of Ubuntu 13.10 on an i7-4771 w/ Intel HD4600 Graphics using a Dell Ultrasharp 1440p monitor via Displayport. Up until today this configuration has been working perfectly, however the latest update appears to have broken my graphics configuration, and xorg is now refusing to go above 1280p resolution. Running xrandr it appears the driver incorrectly thinks my monitor is plugged into the HDMI port and is detecting a max resolution of 1920x1200 instead of 2560x1440. (It's actually plugged in via Displayport). Based on the apt history.log, the latest update was for the kernel. I'm presuming the issue is that the official Intel driver hasn't been updated to support this version? Is there any way to resolve this, or will I need to upgrade to 14.10 to get the latest driver from Intel? Start-Date: 2014-05-28 11:30:57 Commandline: aptdaemon role='role-commit-packages' sender=':1.473' Install: linux-image-extra-3.11.0-22-generic:amd64 (3.11.0-22.38), linux-image-3.11.0-22-generic:amd64 (3.11.0-22.38), linux-headers-3.11.0-22:amd64 (3.11.0-22.38), linux-headers-3.11.0-22-generic:amd64 (3.11.0-22.38)

• How can I connect my USB (HP) printer in 10.4, which can't be discovered and worked in 9.x

  - by Brian

  My printer was working under 9.x. It is a an hp photosmart C3100 series. When I open the Admin- printing. no local printers are found. I try to add via other (My local choices are Serial and other). I have tried many uri's - ipp://localhost:631/ipp, http://localhost/ipp, localhost, 127.0.0.1, etc... None have worked. Under the networked I have tried JetDirect, using localhost and 127.0.0.1 and port 631. I have tried many options under IPP with different variants in the host trying to verify a printer. No luck. I tried LPD/LPR with localhost and tried the probe. no luck. I tried the cups admin via localhost:631 and that didn't work. On the old version its simply found the local printer, I might have picked the driver, I can't remember but it was the photosmart c3100 series that was working. I just can't get 10.4 to print.

• Is it common to only pay developers for the time they said a project would take?

  - by BAM

  I work at a small startup (<10 people), and I was recently assigned (along with one other developer) to a relatively small project. The project involved moving an existing iOS app to Android. The client told us they had built the app for iOS in 300 man-hours. Not knowing at the time that this figure was completely false, we naively and optimistically assumed that if they could build the app from scratch in that amount of time, we could easily "port" it in a similar amount of time. Therefore, we drafted up a fixed-price contract based on 350 man-hours, with a 5 week deadline. (We are well aware now of how big of a mistake this was... Never let the client tell you how long it's going to take!) Anyway, by week 4 we had already surpassed our 350 hours, and we estimated that there were at least 2 more weeks left on the project. We were told to continue working, but that the company could not afford to pay out on overdue projects anymore. I thought this just meant "be more careful about estimates in the future". However a few weeks later, the company president informed us that we would not be getting paid for any time past 350 man-hours. We argued over the issue for almost an hour. He claimed, however, that this is standard practice for many organizations, and that I was unreasonable for making a big deal out of it. So is this really a common thing, or am I justified in being upset about it? Thanks in advance for any advice!

• Creating new games on Android and/or iPhone

  - by James Clifton

  I have a succesfull facebook poker game that is running very nicely, now some people have asked if I can port this to other platforms - mainly mobile devices (and I have been asked to make a tablet version, do I really need a seperate version?) I am currently a PHP programmer (and game designer) and I simply dont' have the time to learn Android and other languages - so I have decided to pay third parties to program them (if viable). The information I need to know is what programming language is needed for the following four devices - Android mobile phone, iPhone, iPad and tablets? Can they all run off a central sql database? If they can't then i'm not interested :( Do any of these run FLASH? Have I covered all my main bases here? For example if a person programs for a ANDROID mobile phone is that to much differant to an ANDROID tablet? They will have slightly differant graphics (because the tablet has a greater screen area might as well use it) but do they need to be started from scratch? Same goes for iPhone/iPad, do they really need to be programmed differantly if the only differance is the graphics?

• wireless blocked after installing ubuntu 12.04

  - by Cornelia Frank

  I am using a lenovo S10-3 ideapad; had no problems with earlier version of ubuntu, only since installing 12.04. Have looked through many of the questions on the same issue and tried potential solutions but cannot seem to solve my problem. The hardware switch is in 'on' position and the wireless light comes on very briefly (2-3 sec) when the laptop starts up but then goes off and stays off. Pressing FN+F5 does nothing at all.

• What is the simplest way to render video into memory (for drawing to a texture) in .NET?

  - by sebf

  In my project I would like to be able to play back video on surfaces in the world. I intend to do this by having the video frames rendered to a block of memory, then use this to update a texture each frame. Everything is in place - except for the part that actually gets the video. I have looked on Google and found that the video library world is very expansive (and geared towards video processing), and am having trouble finding a suitable one. FFMpeg is very comprehensive, but is an entire suite and would take a good amount of work to integrate. So far the most promising library I've found is the one based on the VLC player libraries - by virtue of it using the same resources as VLC Player it is known to be very capable; it also renders to blocks of memory, but the API (at least of the one on Codeplex) is more of a port of the C++ API rather than a managed wrapper. The 'solution' can be any wrapper/API/library, but with characteristics that make it suitable for use in a rendering engine, namely: Renders the video frame data to memory, so it can be picked up and passed to a texture on the GPU easily. Super simple - all that is needed is a way to load, jump and render a frame programatically - ideally it would use the systems codecs and not require an assortment of plugins. Permissive license (LGPL or more free-er) .NET bindings at least; all the better if it is natively managed Can anyone suggest a lightweight, (.NET) library, that can take a video file, and spit out some frames into a byte[]?

• Collision with half of a semi-circle

  - by heitortsergent

  I am trying to port a game I made using Flash/AS3, to the Windows Phone using C#/XNA 4.0. You can see it here: http://goo.gl/gzFiE In the flash version I used a pixel-perfect collision between meteors (it's a rectangle, and usually rotated) that spawn outside the screen, and move towards the center, and a shield in the center of the screen(which is half of a semi-circle, also rotated by the player), which made the meteor bounce back in the opposite direction it came from, when they collided. My goal now is to make the meteors bounce in different angles, depending on the position it collides with the shield (much like Pong, hitting the borders causes a change in the ball's angle). So, these are the 3 options I thought of: Pixel-perfect collision (Microsoft has a sample) , but then I wouldn't know how to change the meteor angle after the collision 3 BoundingCircle's to represent the half semi-circle shield, but then I would have to somehow move them as I rotate the shield. Farseer Physics. I could make a shape composed of 3 lines, and use that as the collision object for the shield. Is there any other way besides those? Which would be the best way to do it(it's aimed towards mobile devices, so pixel-perfect is probably not a good choice)? Most of the time there's always a easier/better way than what we think of...

• Extreme Portability: OpenJDK 7 and GlassFish 3.1.1 on Power Mac G5!

  - by MarkH

  Occasionally you hear someone grumble about platform support for some portion or combination of the Java product "stack". As you're about to see, this really is not as much of a problem as you might think. Our friend John Yeary was able to pull off a pretty slick feat with his vintage Power Mac G5. In his words: Using a build script sent to me by Kurt Miller, build recommendations from Kelly O'Hair, and the great work of the BSD Port team... I created a new build of OpenJDK 7 for my PPC based system using the Zero VM. The results are fantastic. I can run GlassFish 3.1.1 along with all my enterprise applications. I recently had the opportunity to pick up an old G5 for little money and passed on it. What would I do with it? At the time, I didn't think it would be more than a space-consuming novelty. Turns out...I could have had some fun and a useful piece of hardware at the same time. Maybe it's time to go bargain-hunting again. For more information about repurposing classic Apple hardware and learning a few JDK-related tricks in the process, visit John's site for the full article, available here. All the best,Mark

• Set UFW before.rules without restart of server

  - by enedene

  I use UFW on my Ubuntu server. Unfortunately there are no rules in UFW to port forward to another machine.

• Wireless connection disconnects and reconnects with a Netgear WNA1000

  - by William Berkenkamp

  Ever since I made the permanent switch from Vista to Ubuntu i've had wireless connectivity problems. From watching the network manager when it disconnects it seems like it turns off the receiver for some reason. Could it be bad drivers? I used their install software and the site doesn't really offer driver downloads. The adapter is a Netgear WNA1000 if memory serves, and I don't know much about the router except that it's a Motorola Surfboard.

• Impossible quandrary involving UCK, graphics card, and Nvidia drivers

  I have a computer that I want to install Ubuntu on. It is an older gaming computer with a Nvidia graphics card. When I attempt to boot any unmodified Linux distribution onto it, I get a "Boot error" message, which I assume is because the computer uses a discrete graphics card, which the Linux kernel does not have support for. Ordinarily, that would not be a problem, as I would just plug the monitor into the VGA port built in to the motherboard. However, this particular model of motherboard does not have an on-board graphics connector, so I am stuck with using the graphics card connection. That further would not be a problem; all I would have to do would be to use UCK to create a customized Ubuntu image that included the graphics drivers. Except for the fact that the Nvidia Linux drivers must be installed on a computer with a Nvidia graphics card present. So while using UCK, the driver installer fails with a message stating that there is no Nvidia graphics card present. How do I get Ubuntu on my desktop computer?

• Recreating Doodle Jump in Canvas - Platforms spawning out of reach

  - by kushsolitary

  I have started to recreate Doodle Jump in HTML using Canvas. Here's my current progress. As you can see, if you play it for a few seconds, some platforms will be out of the player's reach. I don't know why is this happening. Here's the code which is responsible for the re-spawning of platforms. //Movement of player affected by gravity if(player.y > (height / 2) - (player.height / 2)) { player.y += player.vy; player.vy += gravity; } else { for(var i = 0; i < platforms.length; i++) { var p = platforms[i]; if(player.vy < 0) { p.y -= player.vy; player.vy += 0.08; } if(p.y > height) { position = 0; var h = p.y; platforms[i] = new Platform(); } if(player.vy >= 0) { player.y += player.vy; player.vy += gravity; } } } Also, here's the platform class. //Platform class function Platform(y) { this.image = new Image(); this.image.src = platformImg; this.width = 105; this.height = 25; this.x = Math.random() * (width - this.width); this.y = y || position; position += height / platformCount; //Function to draw it this.draw = function() { try { ctx.drawImage(this.image, this.x, this.y, this.width, this.height); } catch(e) {} }; } You can also see the whole code on the link I provided. Also, when a platform goes out of the view port, the jump animation becomes quirky. I am still trying to find out what's causing this but can't find any solution.

• 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)

• How can I create an orthographic display that handles different screen dimensions?

  - by Piku

  I'm trying to create an iPad/iPhone game using GLES2.0 that contains a 3D scene with a heads-up-display/GUI overlaid on the top. However, this problem would also apply if I were to port my game to a computer and run the game in a resizable window, or allow the user to change screen resolutions... When trying to make the 2D GUI/HUD work I've made the assumption that all I'm really doing is drawing a load of 2D textured 'quads' on the screen and am trying to treat the orthographic projection as an old-style 2D display with 0,0 in the upper left and screenWidth,ScreenHeight in the lower right. This causes me all sorts of confusion when I rotate my ipad into Landscape mode since I can't work out what to put into my projection and modelview matrices to turn everything around the right way. It also gets messy if I want to support the iPad's large screen, an iPhone or a Retina display since I have to then draw three sets of textures for everything and work out which ones to use. Should I be trying to map the 2D OpenGL co-ords 1:1 with the screen? While typing out this question it occurs to me that I could keep my origin in the centre, still running -1/+1 along the axes. This would let me scale my 2D content appropriately on the different screen sizes, but wouldn't I end up with the textures being scaled and possibly losing quality? I'm using OpenGLES 2.0 and have a matrix library that has equivalents to the GLES1.1 glOrthof() and glFrustrum() calls.

• alsa - sound issues on ubuntu 12.04

  - by tam_ubuuser

  i am having an sony E series laptop.i have an HDMI port .at this stage ,i have tested my sound card , which provides audio out on my laptop i.e i could hear songs .my laptop has two sound cards amd 5450 and an intel-hda(alsamixer shows that as s/pdif) . i decided to connect HDMI output to my new HD-TV.but, i could get only visuals on my TV,NO AUDIO OUTPUT ( HDMI cable works fine with win 7).my laptop has two sound cards.but i couldn't switch output to other card.( i don't know ,how to do that) i decided to update alsa. complied the following code in terminal. sudo apt-add-repository ppa:ubuntu-audio-dev/alsa-daily sudo apt-get update sudo apt-get install alsa-hda-dkms then,strangely no login sound, and no audio output on my laptop at all .then, started complied code from step1 sound troubleshooting procedure from offical ubuntu site.then, my speaker icon taskbar disappeared .obivously $aplay -l ,provided output as no soundcards detected . so , i implemented step 4 from that guide, it provides a output of all hardware devices in my laptop. *-multimedia UNCLAIMED description: Audio device product: Cedar HDMI Audio [Radeon HD 5400/6300 Series] vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0.1 bus info: pci@0000:01:00.1 version: 00 width: 64 bits clock: 33MHz capabilities: pm pciexpress msi bus_master cap_list configuration: latency=0 resources: memory:f0040000-f0043fff *-multimedia UNCLAIMED description: Audio device product: 5 Series/3400 Series Chipset High Definition Audio vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 05 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:f5e00000-f5e03fff that command displayed output name of the two cards . but , still i have no positive output on $aplay -l. so therfore, i think alsa couldn't detect my sound cards . is there solution to this problem? it could be better,if alsa would channel output from multiple sound cards ? how should install and configure alsa such that detects HDMI cable as soon i connect to my HD tv? is it possible to alsa and pluseaudio 2.0 to co-exist, if so how?
