  • How to copy existing movie files on ipad to watch?

    - by Rob Van Dam
    I have an iPad and a desktop running Ubuntu 12.04 with lots of movie files of various formats (avi, mp4, m4v, etc). Is it possible to transfer those files from within linux directly to the iPad (without using iTunes to sync) over USB and then play those movies on the iPad without reformatting/resizing all of them? I've used iTunes in a Windows XP virtualbox instance with other iOS mobile devices before but I would prefer a pure linux approach if possible. (I'm creating this question so that I can share the solution I found because I failed to find a simple, satisfactory answer elsewhere).

  • WCF web service with Neural Network

    - by Gary Frank
    I am developing a web service that performs object recognition. It will be available for testing as soon as enough code has been developed, and then officially when it is finished. It is based on a radically new type of artificial neural network that I designed. Its goal is to recognize any type of object within an image. Besides the WCF web service, the project will also create a website to test and demonstrate the web service. Here is a link with more information. http://www.indiegogo.com/VOR

  • MMORPG game balancing

    - by Gary Paluk
    I've seen a couple of examples of some game balancing techniques in books yet they are not comprehensive and not particularly aimed at MMORPGs but I'm looking for practical examples of game balancing techniques for MMORPGs. I am interested to know if anyone has documented the techniques used in popular games with proven success in this area. Ideally, any resource would cover most common types of stats and include layman mathematical models or techniques used to balance game mechanics found in advanced MMORPGs (I know it's a cliché, but WoW style) Any help would be great!

  • htaccess rewrite doesn't work

    - by Raimond van Mouche
    I'm trying to redirect url's in my /joomla/ folder containing "rsform" to the same url but except for /joomla/ /formulieren/. However my tried .htaccess rewrite doesn't work. I tried: RewriteEngine on RewriteCond %{REQUEST_URI} rsform RewriteRule ^(.+)$ http://watervriendengeleen.nl/joomla/ [L,R=301] And other URL related rewrites like Redirect /joomla/index.php?option=com_rsform&formId=12&Itemid=99999 http://sitename.com/formulieren/index.php?option=com_rsform&formId=12&Itemid=99999 which didn't work either. Any thoughts?

  • Installing Ubuntu 12.04 on a single GPT SSD which contains Windows 7

    - by Gary
    I recently bought a brand new 64 bit PC with a (ASUS) motherboard that supports UEFI and a GPT formatted 240Gb SSD, which contains Windows 7 in the first of 3 (80Gb) partitions. When the system arrived, it booted into Windows 7 like a dream, with no problems. I did not originally want Windows, but the manufacturer does not work with Linux (of any flavour), so I thought I would install Ubuntu into the second partition and dual boot. I downloaded the 12.04 64bit version and proceeded to install. Having selected to 'install', the screen became corrupted, with multicoloured garbage across the middle third of the screen !! So, I rebooted and --- MISSING OPERATING SYSTEM !!! The only way I can now get into Windows is via Super Grub2. First question - what went wrong ? 2nd - Will Ubuntu install on a GPT disk partition ? 3rd - Will it install alongside Windows 7 without screwing the boot mechanism ? 4th - How do I do it ? I have scoured the internet looking for appropriate answers and found NONE ! Please help.......

  • How to keep a generic process unique?

    - by Steve Van Opstal
    I'm currently working on a project that makes connection between different banks which send us information on which that project replies. A part of that project configures the different protocols that are used (not every bank uses the same protocol), this runs on a separate server. These processes all have unique id's which are stored in a database. But to save time and money on configurations and new processes, we want to make a generic protocol that banks can use. Because of PCI requirements we have to make a separate process for every bank we connect to. But the generic process has only 1 unique identifier and therefor we cannot keep them apart. Giving every copy of that process a different identifier is as I see it impossible because they run entirely separate. So how do I keep my generic process unique?

  • Possible automated Bing Ads fraud?

    - by Gary Joynes
    I run a website that generates life insurance leads. The site is very simple a) there is a form for capturing the user's details, life insurance requirements etc b) A quote comparison feature We drive traffic to our site using conventional Google Adwords and Bing Ads campaigns. Since the 6th January we have received 30-40 dodgy leads which have the following in common: All created between 2 and 8 AM Phone number always in the format "123 1234 1234' Name, Date Of Birth, Policy details, Address all seem valid and are unique across the leads Email addresses from "disposable" email accounts including dodgit.com, mailinator.com, trashymail.com, pookmail.com Some leads come from the customer form, some via the quote comparison feature All come from different IP addresses We get the keyword information passed through from the URLs All look to be coming from Bing Ads All come from Internet Explorer v7 and v8 The consistency of the data and the random IP addresses seem to suggest an automated approach but I'm not sure of the intent. We can handle identifying these leads within our database but is there anyway of stopping this at the Ad level i.e. before the click through.

  • Extension GLX missing...on a desktop PC

    - by Bart van Heukelom
    I just installed Ubuntu 12.10 on a new PC with an Nvidia GTX 560 graphics card, but after installing the Nvidia proprietary drivers (either -current or -current-updates), Unity won't start. When trying to start it manually I get the message "extension GLX missing". I've searched around and found results like this question which point out it's a problem with Nvidia Optimus laptops. However, I don't have this problem on a laptop, but on a desktop PC. lshw output for the graphics card: *-display description: VGA compatible controller product: GF114 [GeForce GTX 560 SE] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nouveau latency=0 resources: irq:16 memory:f4000000-f5ffffff memory:e0000000-e7ffffff memory:e8000000-ebffffff ioport:e000(size=128) memory:f6000000-f607ffff and CPU: *-cpu description: CPU product: Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz vendor: Intel Corp. physical id: 40 bus info: cpu@0 version: Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz slot: SOCKET 0 size: 1600MHz capacity: 3800MHz width: 64 bits clock: 100MHz capabilities: x86-64 fpu fpu_exception wp vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm pcid sse4_1 sse4_2 popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm ida arat epb xsaveopt pln pts dtherm tpr_shadow vnmi flexpriority ept vpid fsgsbase smep erms cpufreq configuration: cores=4 enabledcores=4 threads=4

  • What is your preferred font for working with code and data?

    - by Gary
    The features I would look for in a 'programmers' font are Monospaced (maybe less important for code, but more important for data) Distinguishable characters. Often I (uppercase i), 1 (one) and l (lower-case L) can be confusing, as can O (upper-case o) and 0 (zero). I'd be interested other character issues, especially in accented or extended character sets. Free Windows / Linux / OSX Legible on screen and printouts at smaller sizes I've community wiki'd this. I'm really looking for a list of fonts that qualify. From that list, people can pick what looks good to them.

  • Loadbalancing Questions

    - by Van Holtz
    I have been learning networking for about 4 months. Wrote a single standalone Multiplayer server and succeeded with authoritative approach. Now I want to extend it by splitting the single server into clusters to allow even more players to log in to avoid latency issues. Now I have protyped the Loadbalancing server and its running pretty good so far. This is my architecture, I have a master server which acts as a proxy, every sub servers(chat, login, game) connect to the master server as well as all the clients. when a client connects, Client Request: Send Request - MS(Master) - Decides which SS(SubServer) to forward to - Forwards Request to SS - SS - Analyze Message - Send Response to MS - Decides which Client to forward to - Forwards Response to Client Well, it looks like its going through lots of stages. it takes double the time to process the message than a single server approach. i feel like my model isnt the best or i may be wrong. is there any better model or the one they use in professional games? I still want a Master-SubServer approach. I just want to clarify that I'm going in the right direction before writing all my codes. Thanks for any answer :)

  • pointer jumping about Lubuntu 12.04

    - by Gary Kirkpatrick
    Using 12.04 on a Samsung NC110. If I disable Touchpad, the cursor does not jump about while typing. This is very very annoying. Tried this tutorial, but this does not help. The problem occurs even when my fingers are well away from the Touchpad. I wonder if another key or key combination causes this problem? I sure could use some help on this. I have had this problem with various versions of Ubuntu and now Lubuntu.

  • Expiring timed actions a good idea?

    - by Bart van Heukelom
    We have an online game where players sometimes have to wait a while (say 30 minutes) before a process they intiated completes. This encourages them to come back later. An example of this is growing crops in Farmville or basically any action in the Sims Play4Free. Now, however, there is the idea to let these processes expire, so if the player doesn't 'reap' them in time (e.g. within 4 hours) they are aborted. I'm a bit sceptical about this. How will this make players come back more often? Is not the reward of reaping the process enough for that? Can we expect players to fit their daily schedule around our game, maybe even set the alarm clock at night? Won't this just cause players to give up on starting these processes in the first place? I realise this may be too subjective for this site, so I'll end with a concrete question: Do (m)any other online free-to-play games employ this technique?

  • RTS Game Style Application [closed]

    - by Daniel Wynand van Wyk
    My question may seem somewhat odd, but I hope that my specifications will clarify EXACTLY what it is that I am after. I need some help choosing the right tooling for a particular endeavour. My background is in desktop application development and large back-end systems. I have worked primarily on the Microsoft stack using C# and the .Net framework. My goal is to develop a 2D, RTS style, interactive office simulation. The simulation will model various office spaces, office equipment, employees and their interactions with one another. The idea is to abstract the concept of an office completely. Under the hood the application will do many things that are nothing like a game. This includes P2P networking, VPN tunnelling, streaming video, instant messaging, document collaboration, remote screen sharing, file-sharing, virus scanning, VOIP, document scanning, faxing, emailing, distributed computing, content management and much more! A somewhat similar thing has been attempted by IBM, where they created a virtual office in second life. If their attempt was a game, the game-play would be notably horrible, to say the least! The users/players will drive and control my application through the various objects modelled in the simulation. A single application capable of performing all of these various tasks would be a nightmare to navigate for even the most expert user. Using the concept of a game, I can easily separate functionality by assigning them to objects that relate 1-1 with their real world counter-parts. This can greatly simplify computing for novice users, with many added benefits in terms of visibility, transparency of process and centralized configuration. My hope is to make complex computing tasks accessible to all kinds of users and to greatly reduce the cognitive load associated with using the many different utilities and applications inside office settings. The complexity is therefore limited to the complexity of the space in which you find yourself. I want the application to target as many platforms as possible and run on computers that have no accelerated graphics capabilities. The simulation won't contain any of the fancy eye-candy you find in modern games, to the contrary, my "game" will purposefully be clean and simple. The closest thing I could imagine would be an old game like "Theme Hospital" or the first instalment of "The Sims". All the content will be pre-created and not user-generated like Second Life. New functionality will be added via a plugin system. Given my background and nature of my "game", I would like to spend most of my time writing code that does not have to do with the simulated office, as the "game" is really just a glorified application menu. I have done much reading about existing engines, frameworks and tools. I need the help of an experienced game developer who has tried and tested various products over the years who can guide me in the right direction given my very particular needs. I would appreciate any help I can get!

  • System resets to login screen spontaneously

    - by Bart van Heukelom
    Now I'm experiencing spontaneous resets of the desktop environment (when logged in and working normally), where the screen will go black, then reset to the login screen. The resets appear to be random, though there is a chance it occurs more when using Nautilus. The screen goes black instantly, e.g. there is nothing like a disappearing launcher or window borders. Where can I begin finding the cause? (Note: I've recently upgraded from 11.04 to 11.10, then 12.04.)

  • sudo: unable to resolve host ubuntu-server

    I have a problem with sudo.

  • Easy road from DisplayObject to Molehill?

    - by Bart van Heukelom
    I have a finished Flash game which is rendered using the built-in display tree, i.e. Bitmaps contained in Sprites (and a text here and there, few vector graphics, and one bitmap-filled shape). For extra performance, I'd like it to use Molehill for rendering, but that's not possible out of the box. What's the easiest way to make this game use Molehill when available, but fall back to the current method if it's not available?

  • Rendering only a part of the screen in high detail

    - by Bart van Heukelom
    If graphics are rendered for a large viewing angle (e.g. a very large TV or a VR headset), the viewer can't actually focus on the entire image, just a part of it. (Actually, this is the case for regular sized screens as well.) Combined with a way to track the viewer's eyes, you could theoretically exploit this and render the graphics away from the viewer's focus with progressively less details and resolution, gaining performance, without losing perceived quality. Are there any techniques for this available or under development today?

  • How to Organize Subdirectories? [closed]

    - by Gary Iverson
    I am working on my first major (several hundred pages) website design and development project. I want to create subdirectories for each of the website's categories, which in turn have their own subdirectories for easy user navigation. Example: website.com/directory. I am aware that by placing an index.html file within each directory, the browser automatically detects and navigates to that page, but that seems like a messy solution (having multiple index.html files, albeit in distinct folders), and I cannot imagine everyone does that. So my question is...how do you properly organize and use subdirectories?

  • Which parallel pattern to use?

    - by Wim Van Houts
    I need to write a server application that fetches mails from different mail servers/mailboxes and then needs to process/analyze these mails. Traditionally, I would do this multi-threaded, launching a thread for fetching mails (or maybe one per mailbox) and then process the mails. We are moving more and more to servers where we have 8+ cores, so I would like to make use of these cores as much as possible (and not use 1 at 100% and leave the seven others untouched). So conceptually, as an example, it would be nice that I could write the application in such a way that two cores are "continuously" fetching emails and four cores are "continuously" processing/analyzing the emails (since processing and analyzing mails is more CPU intensive than fetching mails). This seems like a good concept, but after studying some parallel patterns, I'm not really sure how this is best implemented. None of the patterns really fit. I'm working in VS2012, native C++, but I guess from a design point of view this does not really matter and just some pointers on how to organize this would be great!

  • ubuntu-overlay-scrollbars set to false shows no arrows in several cases

    - by Willem van Gerven
    I'm running 12.04, and prefer the more conservative style "normal" scrollbars over the overlay scrollbars. I have set them to false in the terminal: gsettings set org.gnome.desktop.interface ubuntu-overlay-scrollbars false However after doing so, with some apps (e.g. Nautilus, Document Viewer) my scrollbars only view a vertical bar, but no arrows on the top and bottom to scroll up and down. With some programs these are shown though, for instance Gummi and Texmaker. It would make a big difference (for instance when having to scroll pdf documents containing several hundreds of pages) to have those arrows reinstated. Is there any way to make this work?

  • Directing Multiple ccTLD's to 1 gTLD with a country specific subdirectory?

    - by Pascal Van Opzeeland
    We have multiple ccTLDomains and are thinking about how to best combine these into one. We want to do this to focus our link building efforts. We are running a website through which we offer a software-as-a-service. Therefore we could potentially sell to any country in the world. However, Germany is our most important market. We currently have a .com, .de, .nl. and .pl domain. All these domains have a high amount of unique content pages. What we are planning is to change everything to .com with language-based subdirectories, so .com/en/, .com/de/, etc. I have two questions concerning this issue: 1) How much of an advantage does a ccTLD have over a gTLD with country specific subdirectories in search rankings? So let’s say .de versus .com/de/? 2) How could we best redirect the visitors of our old ccTLD’s to our gTLD’s subdirectories? We would like to loose as few search engine rankings as possible. Thank you for your help.

  • How to read data from a large number of files in a folder? [closed]

    - by Gary Dhillon
    I seem to be having some trouble figuring out a solution for a problem. See the thing is, my code is supposed to read a lot of data from a bunch of files. I've been thinking of two different approaches: 1) the first one seems simpler, I ask the user if they would like to examine the next file or just quit out of the program.( I believe this is simpler and would take less time to run through.) 2)It reads through all the files and outputs the results for each of them, and then a shared result for all of them.( I think this would be better for what I've been asked to do and it saves the user some hassle.) If anyone can tell me how to code either of these in C++, I would be very grateful. Here is a sample of the file: 0 -- 19 weight 0 -- 20 weight I use this to determine density and possibly ignore the weights which is a number.

  • How can I access old KMail emails after upgrading to Ubuntu 11.10?

    - by Gary Kleppe
    I initially installed Ubuntu 11.04 and used KMail for my email. All well and good. Then I upgraded to Ubuntu 11.10. Presumably an upgrade of KMail took place as part of this. Now KMail won't even run; when I try, it tells me "Failed to fetch the resource collection" and crashes. I don't mind switching to another email client, but I'd very much like to be able to recover all of the emails I have stored in KMail. Any suggestions on how to do this? Thanks for any help anyone can provide.
