  • Enable remote VNC from the commandline?

    - by Stefan Lasiewski
    I have one computer running Ubuntu 10.04, and is running Vino, the default VNC server. I have a second Windows box which is running a VNC client, but does not have any X11 capabilities. I am ssh'd into the Ubuntu host from the Windows host, but I forgot to enable VNC access on the Ubuntu host. On the Ubuntu host, is there a way for me to enable VNC connections from the Ubuntu commandline? Update: As @koanhead says below, there is no man page for vino (e.g. man -k vino and info vino return nothing), and vino --help doesn't show any help).

  • Bug once in a while,but high priority

    - by Shirish11
    I am working on a CNC (computer numerical control) project which cuts shapes into metal with help of laser. Now my problem is once in a while (1-2 times in 20 odd days) the cutting goes wrong or not according to what is set. But this causes loss so the client is not very happy about it. I tried to find out the the cause of it by Including log files Debugging Repeating the same environment. But it wont repeat. A pause and continue operation will again make it to run smoothly with the bug reappearing. How do I tackle this issue? Should I state it as a Hardware Problem?

  • JavaFx a-t-il encore une chance de s'imposer face à Flash, Silverlight et l'émergence du HTML 5 ? Ou

    JavaFx a-t-il encore une chance de s'imposer Face à Flash, Silverlight et l'émergence du HTML 5 ? JavaFx a été lancé il y a trois ans pour développer des applications lourdes. Très vite, les développeurs l'ont utilisé pour des applications multimédias et pour faire du web java (notamment des Rich Internet Applications ou RIA). La plateforme - qui se compose du langage de script JavaFX, une plateforme pour client lourd et une intégration avec la machine virtuelle Java - entendait ainsi répondre ainsi aux besoins d'un marché où la compétition fait désormais rage avec, entre autres, des acteurs aussi importants que Flash de Adobe et Silverlight de Microsoft.

  • Services - Separate Sites or One Site - Impact on SEO

    - by Lynda
    I have a client who is a lawyer that specializes in Criminal Defense and DUI, however, he does not show up well in Google. In researching the sites that rank better have much more content for those specialties than his site does and my thought it that he needs to add more quality content to rank better for those searches. On his site he mentions his specialties, but also he has various personal things on his sites that reflect his interest. These are clearly separated from the business portion. My questions are should he 1) separate his personal information into a new domain and 2) should he have a separate URL for each of his specialties? OR would one URL work as long as everything is clearly separated? I read once that for legal services to rank well you should make a separate site for each specialty and have that site focus solely on that service.

  • What makes it hard to protect from hacks/bots in BF3 and Quake Live?

    - by Jakub P.
    After playing these games, asking other players/admins, and reading online I am led to believe that Quake Live and Battlefield 3 are frequented by bots and there are plenty of hacks of various kinds. I'm confused how this is possible, or even easy seeing how many players have access to these kinds of "tools" (sic). Isn't it possible for the game authors to digitally sign the game executables so that when they run, the server can ensure only the allowed client is sending commands, thus preventing any kind of abuse? I.e. every player command would be signed by a private key, or symmetrically encrypted (not sure which would make more sense). I understand that players can look at the running executable's behavior (memory etc.), but if games are apparently so easy to hack, shouldn't most apps be hacked as well (e.g. Skype, all DRM running on Windows etc.)?

  • How to use OpenGL functions from multiples thread?

    - by Robert
    I'm writing a small game using OpenGL. I'm implementing basic networking in this game and I'm facing a problem. I have a thread in my client socket class that check for available data, when there are data I raise an event like this : immutable int len = this.m_socket.receive(data); if(len > 0) { this.m_onDataEvent(data); } Then on my game class, I have a function that handle and parse data like this : switch(msgId) { case ProtocolID.CharacterData: // Load terrain with opengl, character model.... Im not able to call opengl functions because my opengl context is created from a different thread. But I really don't know how I can solve this problem, I tried Google but it's really hard to find a solution. I'm using D programming language if it can help.

  • Today is my first day in the land of backbone.js

    - by Andrew Siemer - www.andrewsiemer.com
    I am semi-excited to say that today is my first day into the land of backbone.js.  This will of course take me into many other new javascript-y areas.  As I have primarily been focused on building backend systems for the past many years…with no focus on client side bits…this will be all new ground for me.  Very exciting! I am sure that this endeavor will lead to writing about many new findings along the way.  Expect the subject of near future postings to not be related to MVC or server side code. I am starting this journey by reading through the online book “Backbone Fundamentals”.  http://addyosmani.com/blog/backbone-fundamentals/  Has anyone read this yet?  Any feed back on that title. I have read though Derrick Bailey’s thoughts here and here…also very good. Any suggestions on other nuggets of learning backbone?

  • Best way to handle realtime melee AI in authoritative network environment

    - by PrimeDerektive
    So i've been working on a multiplayer game for a bit; it's a co-op action RPG with real-time combat. If you've seen or played TERA, I'd say it's comparable to that, but not an MMO, heh. I'm currently handling the AI units authoritatively, the server calculates their pathing, movement, and pursue/attack logic, and syncs the movement to the clients 15x per second, and the state changes when they happen. When I emulate 200ms ping, though, the client can perceive being out of range to an AI's attack, but still take the hit, because on the server he hadn't moved that far yet. This also plays hell with my real-time blocking. I don't really want to allow the clients to be allowed to say "that was out of range" or "I blocked that", but I'm not really sure how else to handle it.

  • How to force Empathy Internet Messaging to change default webcam?

    - by user43430
    I just recently bought a new webcam. It is USB powered. For personal reasons, I wish to not use the built in webcam that came with my netbook. I want to use this new one. I love empathy, it is a great chat client. But, I can't seem to switch my default webcam in empathy from the built in webcam, to the one I just bought. So, is there a way to force empathy to use the USB powered webcam, rather than the built in webcam?

  • How to properly URL/domain forward

    - by NRGdallas
    No clue on a title for this, someone feel free to suggest an edit. I have a client that has a website. He owns around 200 domains, and wants each domain to contain content from the main website. The header, footer, and navigation bars will remain the same for each domain, but the actual page content will vary (obviously duplicate content issues, open to suggestions) He wants each individual page to be its own separate domain, rather than a url within the main domain. (page1.com page2.com etc - NOT site.com/page1.html, however the file is actually hosted at site.com/page1.html - all links will direct to site.com/whatever accordingly) What would be the best place to start reading / learning on how to do this, and what concerns/considerations should be taken into mind?

  • Situations that require protecting files against tampering when stored on a users computer

    - by Joel
    I'm making a 'Pokémon Storage System' with a Client/Server model and as part of that I was thinking of storing an inventory file on the users computer which I do not wish to be edited except by my program. An alternative to this would be to instead to store the inventory file on the server and control it's editing by sending commands to the server but I was wondering if there are any situations which require files to be stored on a users computer where editing would be undesirable and if so how do you protect the files? I was thinking AES with some sort of checksum?

  • what's best language to mate with Adobe Flex-based GUI for math crunching?

    - by gkdsp
    Hi, I'm not a software expert but need to outsource a web-based scientific GUI application, and I'm considering Adobe Flex. My math routines are currently in Javascript and C/C+. Having no experience with Flex, was hoping someone could help me understand what options are available for performing (preferably fast and efficient) CLIENT-side calculations. That is, can Flex interact with Javascript and/or C easily? If not, is actionscript or other language preferred? Downsides/tradeoffs? Need functions like LOG10, LN, SQRT, and would be nice to also have the error function (ERF) and complementary error function (ERFC), although I may be able to derive these last two from more basic functions if necessary. Thanks!

  • Are python's cryptographic modules good enough?

    - by Aerovistae
    I mean, say you were writing professional grade software that would involve sensitive client information. (Take this in the context of me being an amateur programmer.) Would you use hlib and hmac? Are they good enough to secure data? Or would you write something fancier by hand? Edit: In context of those libraries containing more or less the best hashing algorithms in the world, I guess it's silly to ask if you'd "write something fancier." What I'm really asking here is whether it's enough on its own.

  • How do you break down a new project with an existing mega PHP site?

    - by Caveatrob
    I've got to dive into a very large PHP site and have my first client meeting today. All they gave me so far was the URL. How do you guys go about gathering/structuring/documenting and preparing for a new project in a PHP environment? What things do you ask for up front? PS - I know there are other general questions about this but I want a PHP-flavored one, including tools (even if universal) and approaches. Thanks!! I'm excited but also scared.

  • Implementing a JS templating engine with current PHP project

    - by SeanWM
    I'm currently working on a PHP project and quickly realizing how useful a templating engine would help me. I have a few tables whose table rows are looped out via a PHP loop. Is it possible to use just a JS templating engine (like Handlebarsjs) to also work with these tables? For example: $arr = array('red', 'green', 'blue'); echo '<table>'; foreach($arr as $value) { echo '<tr><td>' . $value . '</td></tr>'; } echo '</table>'; Now I want to add a column via an ajax call using a JS templating engine. Is this possible? Or do I have to use a templating engine for both server side and client side?

  • Active Directory auto login to website for domain users

    - by Darkcat Studios
    I am putting together an Intranet for a company - I have set up authentication to get into the Intranet from a login box linked to AD via LDAP/ However the client wants (if possible) to have users automatically authenticate into the intranet if they are logged into the domain. AD and IIS7.5 are on separate servers (in the same network). I believe that I need to use WindowsAuthentication to do this - but will that work? as the web server is not part of the domain: do I need to tell IIS where the AD server is? The next part could be more complex: once the user has authenticated, I need to drag user details from AD about the user, I guess with LDAP, however I will need to know the user's username in order to do this, won't I? as the user hast had to type this in, how do I get that? The intranet site is in asp.net 4 VB.

  • Where is the Accessibility mouse click lock?

    - by user10133
    I've been a user of Linux on the desktop off and on again over the years. I very nearly switched my primary computer to Ubuntu prior to the release of Windows 7. There were a few, but significant issues at the time that prevented wholesale adoption, mostly tethering with my phone and lousy VPN Client. One key component I could count on was the Accessibility features. I have recently installed Ubuntu 10.10 and am considering giving it another try, but it appears Ubuntu has taken a leap backwards in that it no longer has a click lock feature for the mouse. Basically I need the ability to press and hold the left button to trigger a locking of the button so I can move the mouse by way of a trackpoint with my prosthesis. I absolutely require this feature and it is a deal breaker if it won't work. I've tried the Dwell keys but this is a chaotic control at best. I've never been able to manage a drag of any kind.

  • Game testing on Android - emulator or real devices?

    - by n00bfuscator
    I am working at a localization agency and we have been approached by a client about testing their games on iOS as well as Android. Testing on iOS seems fairly easy as we can just buy a couple of devices and we should be covered. For Android it seems to be completely different. From what i found, the emulator can cover all API levels, screen sizes and such, but i hear it's buggy and nothing could replace testing on real devices. With the vast amount of Android devices out there and the rate at which new devices are released it seems impossible to keep up. How can i test games (localization and functional) on Android covering all compatible devices?

  • Do I have to deliver my utility and helper code to clients?

    - by deviDave
    Over the years I've created a bunch of Java utility and helper libraries which I just attach to new projects. Then, when I deliver code to my clients, I send all the code except for the libraries themselves (not JARs but source code files). A client complained that he could not compile the project as some libraries were missing. I tried explaining him about my own libraries, but he was not satisfied. How do you handle such situations? I am still apporting changes to these libraries often and I cannot compile JARs each time I start working on some new project. How to overcome this issue - not to share private libraries (personal intellectual property) and have happy clients?

  • How do I manipulate the Url of my Silverlight testpage.aspx?

    - by Daniel
    I am making an XNA game using Silverlight over the web. My testpage.aspx is linked to from a previous page where the client selects certain elements. The testpage.aspx URL changes depending on what I have sent to it. Now in my mainpage.cs file I would like to call certain functions depending on what was passed, but I am unsure how to manipulate or even access the URL. Is there a specific class in the Silverlight library I can use? Thank you for your time.
