  • Thread problem updating Windows Forms control in XNA C#

    - by Luis
    I'm development a network card game, and for now i've two players connected but there is a problem with one of them, this one can't do anything on the game. Looks that screen was blocked. I'm think that is because a code i used before. That code is: if (InvokeRequired) { this.Invoke(new MethodInvoker(delegate { ... })); return; } The code above is surrounding code to changing Button values, make connection with server and create game window. Without this code a warning is shown. InvalidOperationException was unhandled Cross-thread operation not valid: Control 'startGameButton' accessed from a thread other than the thread it was created on.

  • What is the best idea to put available OS (linux) and Web application to client?

    - by Fernando Costa
    After a year programming a web based business management system, I got my idea divided into two differents ways to do what I'm doing... I will try to explain in follow lines: First I will describe my enviroment: Webserver: apache, ngynx Programming Language: PHP, Shell Script, Java Script, SQL Database: Mysql Operating System: Linux, UNIX (All Distros) (If manually configured works on windows) Authentication Server: FreeRadius First situation I have my application running on this enviroment that I had just described before, as my application is a SaaS app, then I have my own server to run it all and customers pay to use it as a service accessed by webbrowser. Second Situation The same as before but with one big difference, everything (environment) is installed in the customer, then I need to cryptography all my codes (It includes PHP and Shell Scripts). I think this situation is most difficulty, but I would like to hear it from different points of view.

  • Black screen on latest Nvidia Cards when starting LightDM/Ubuntu

    - by Luis Alvarado
    Today I installed an Nvidia GT440 on my computer, changing the one that existed there, an Nvidia 9500GT. After changing it I started getting a problem where the screen just went black when loading the lightdm login screen (Where I punt my user and password). The thing is, if I disconnect the VGA cable and connect it again I get to see the lightdm greeter and everything works perfect. The problem is that I have to connect/disconnect every time I reboot the PC. I tried installing the 285.xx drivers. Same problem. I removed the Nvidia drivers installed with Jockey, rebooted, same problem. I install the current 280.xx again, same problem. After all that I installed a fresh install of Ubuntu, selected to install the Nvidia drivers while installing it from the livecd. After booting the same problem appeared. Dmesg does not say anything wrong about it. Same goes for the log from Jockey. What else should I check or what to do to solve it. Just to clarify, this does not happen BEFORE the lightdm greeter appears. Am guessing before the actual use of the video card with X starts with all the 2D/3D stuff that is used in ligthdm and unity. I can use any tty and even see the Ubuntu logo when starting. UPDATE: When I open a game in fullscreen the problem appears again. I have to unplug the monitor cable and plug it back in to see the game. Then when I quit the game I have to do it again to see the desktop. UPDATE 2: Today I bought a HDMI cable, connected the video card to the TV am testing it with and it actually did log in correctly without any black screen but it shows the resolution a little over the actual size of the screen. So I see only half of the launcher since the left side of it is hidden outside of the real resolution and the top bar is beyond the resolution. So the black screen is related to the VGA connection.

  • What has Ubuntu contributed to the Linux Kernel?

    - by Luis Alvarado
    This question is similar to this one: What unique enhancements and features has Ubuntu brought to the Linux Community but in this case it is directed towards what has Ubuntu contributed to the official Linux Kernel. For example, many times I hear about Intel contributing to patches for the Linux Kernel like the RC6 latest patches and any other related to the recent Sandy/Ivy Bridges. In another group, Android did an upstream patch and a lot of ARM patches have also come to the Linux Kernel. I have seeing only a small percent of companies and groups that have contributed to the Linux Kernel (http://kernel.org) but I want to know, since the beginning of Ubuntu till now, what has Ubuntu contributed to the Linux Kernel in regards to any aspect of the kernel. For Kernel information I typically go to http://kernelnewbies.org and http://kernel.org

  • How to drag from a background window to the front window

    - by Luis Alvarado
    Is the following I will explain possible with a key combination? Here is the image: As you can see, the terminal is the focus window (Front window) and Nautilus is in the background (Back Window). How can I grab a folder or file from Nautilus without loosing focus on the terminal (Without making the terminal go to the background and Nautilus to the front) and drop it in the terminal?. What I want is not to have to ALT+TAB again just to do this. Options like resizing the windows to fit the screen are not what I am looking for. Like in the image, we have a fullscreen window that we want it to stay like that. We can drag the terminal window around but anytime I access the background nautilus window, I should not loose focus on the terminal (It should not go to the background every time I access Nautilus). Maybe like a key combination that freezes the current focus windows positions and I can drag from background windows to background windows or background windows to the front focused one.

  • Multiple monitors showing same screen but different resolutions

    - by Luis Alvarado
    Is it possible to have 2 or more monitors showing the same screen, for example the same desktop but with different resolutions. Like the clone option in Nvidia or the mirror option using the Display settings in Ubuntu but instead of showing the same output with the same resolution, the both show the same output using a resolution that is native for each monitor connected. In my case if I have a netbook that has max resolution of 1360x768 and a TV that has 1280x1024, the would both show the same desktop but each with their own resolution that is compatible for each device. This would help in trying to find a resolution that works on both monitors and in cases like a mini netbook and a huge TV it would solve issues like having max 800x600 in one monitor and min 1024x768 in the other. In the case I tested I was using an HDMI cable but this question also involves VGA and any other connection. I have 3 tests scenarios for this: Scenario 1 - Laptop HP DV6000 (Intel Integrated Video) with 1360x760 connected to a Samsung LED 42 TV that has 1280x900. Scenario 2 - Laptop EEE with 1024x600 (Intel Integrated Video) connected to Sony LCD TV that supports 1280x900. Scenario 3 - Intel Desktop with Nvidia 440 GT with HDMI connected to Soneview 32' TV that supports 1920x1080 and VGA connected to an Epson Video Beam that supports 1280x1024 max. In this 3 scenarios I need to be able to show the same desktop and same views but on different resolutions for each output device. UPDATE: Tested with Xubuntu and the way it handles multiple monitors is precisely what I am asking. The ability to handle the resolution of different monitors showing the same thing.

  • Apps capable of mounting/unmounting CD/DVD Images with multi-sector or protected format

    - by Luis Alvarado
    What apps for Ubuntu exist that can mount/unmount CD/DVD images. Image formats like cue, bin, iso, nero format, etc... Needed features: Emulate protected CD/DVD like Daemon-Tools Mount multi-sector images Converting other formats (including multi-sector images) to ISO format. UPDATE - Updated question to "need the 3 features above instead of having them as optional". This 3 features are needed to be able to use images that have any of this features enable. For normal mounting/burning image apps you can see here: How can I graphically mount ISOs? Can I mount an ISO without administrative privileges? How burn or mount an ISO file?

  • How to clean and add options to the Open With list of apps

    - by Luis Alvarado
    After installing several PPAs (Wine, PoL) and opening several files with other apps (Like changing from Totem to VLC) I discovered that the Open With option had 2 problems: Many items on the list are duplicated (As seen on the image for "A Wine Program") Sometimes the app I want to use to open is not shown there (For example, Virtualbox or VLC) So how can I edit this list to clean the duplicates and add missing apps from the list.

  • How to merge multiple internet connections into one

    - by Luis Alvarado
    My PC has 2 wired cards. Both gigalan. It also has 2 wireless cards. One broadcom with proprietary drivers and ralink with open software (which works much better than broadcom). My cellphone can share its connection wirelessly to my PC. But I also have a wired connection. So I have multiple connections that I can use to have internet. How can I merge 2 or more connections together and balance them to enjoy one unified internet experience that it is the sum of all internet connections connected to it. For example if I have an internet connection that offers 1024KB/Sec and another that offers 512KB/Sec and one small one that offers 128KB/Sec, after load balancing and merging all connections, I could download at a speed of 1664KB/Sec using all 3 internet connections as one for example. This question has always intrigued me.

  • XNA 4.0 Point Vertex Rendering

    - by luis
    I have a buffer of about 134 million particles and a very powerful computer to render them smoothly but I am getting an error when trying to render them as primitive lines it says I cannot render more than around 1 million. I wonder how can I do this, also if is there a better way to render this other than with lines, I'm comfortable with having 1 pixel points or anything as long as the vertices are shown all the time. I'm basically just plotting the points. thanks.

  • How to see the discharge rate of the battery

    - by Luis Alvarado - The Wolverine
    Maybe this question was made earlier but I can't find it. I want to see a terminal command or gui program that can show me the discharge rate of the battery. What hardware parts or programs are using more watts. EDIT: Found additional information regarding my question when using for example PowerTop: https://bbs.archlinux.org/viewtopic.php?id=128319 https://bugs.archlinux.org/task/26416 Both related to the having disable ACPI_PROCFS_POWER in the kernel.

  • Chrome + Touchscreen + Unity (14.04)

    - by Luis Fernando P. Gonzalez
    I've got a Dell 14R with touchscreen with Ubuntu 14.04. When I start Google Chrome by clicking the launcher with the TouchPad or with the Super+ combination, touch support in Chrome doesn't work. When I touch some element, it only gets focus, but doesn't activate the element (button, field, etc). And touch gestures don't work. In the other hand, if I start Chrome by touching the launcher button, touch scroll works in Chrome, even flicking to left does back to the previous page, etc. It doesn't makes sense to me, but is always like this, even across reboots. Anyone can confirm this? Any idea on how to fix?

  • Ubuntu 12.10 - VirtualBox not sharing internet with guest system

    - by Fernando Briano
    I went from ArchLinux to Ubuntu on my dev box. I use VirtualBox to test web sites on Windows and IE. I have my Windows 7 VirtualBox image running on Ubuntu's VirtualBox. Back with ArchLinux, internet worked "out of the box" on the Windows boxes. I left the default options on the box's Network Options (NAT). The Windows machine shows as "connected to ethernet" but reports: The dns server isn't responding So I can't access Internet from there. I tried searching for Ubuntu's official docs but they seem pretty outdated. I tried using my old boxes from Arch (which boot normally but have no internet) and creating a new box from Ubuntu itself, but still get the same results. Update: I'm using VirtualBox 4.1.18 from Ubuntu's repository (apt-get install virtualbox).

  • Does the lense for videos search youtube correctly

    - by Luis Alvarado
    When I search in youtube.com for "Erika Tipo 11" I get videos about the actual show. When I do the same using the Dash video Lense I get anything else except the actual show. I mean I even get chinesse stuff, some yoga lessons and anything VERY out there that is not even remotely related to the show. Now my questions are: Does the video lense search in a similar way as searching in youtube/vimeo/any other video site? Is there an option apart from the Filter settings to configure the behavior of the search so it searches in a similar way as one would do when searching from the actual site.

  • Pen drive is recognizing as a USB Internet Dongle which connects to the PC. How do the Pen drive configure well in Ubuntu 12.04?

    - by Eranga Fernando
    Every time I connect my Pen drive it recognizes as more like a Dongle. The reason that I'm telling that if I connect it to the PC when I'm on the INTERNET, it will automatically copy all the files which are in the Dongle. So, I can't recognize which one is the Pen drive when I want to safely remove the device. I'm not sure whether it is the Pen drive or the Dongle..? Can anyone give me a good advice how to solve this problem?

  • Play videos with libwebkit in Ubuntu 11.10 server

    - by Luis Fagundes
    I'm using libwebkit (with python-webkit) to render a page that plays a video. This application works fine in a Ubuntu 11.04 Desktop, Nvidia card and lots of libraries and software installed, but in a fresh Ubuntu 11.10 Server with intel 82945G/GZ card the video does not play. I guess either some codec package is missing or it's a driver problem. What could be missing for this to play? I'm trying with this video: http://video.eustasy.co.uk/480/ EDIT: doesn't look like a driver problem. With chromium I can play the video, but with libwebkit + python-webkit the video just shows the first frame and doesn't play. Any hints on what package could be missing? SOLVED: apparently it had to do with lack of audio. While chrome would play the video with no sound, libwebkit wouldn't start video. Adding user to audio and video groups solved the problem.

  • What tools exist to report bugs

    - by Luis Alvarado
    As of today I only knew about ubuntu-bug which I could use to report bugs about a specific program. But now I learned about apport-collect and apport-bug which basically are: apport-bug - Reports problems to launchpad using Apport to collect a lot of information about your system to help the developers fix the problem and avoid unnecessary questions and answers. apport-collect - Works as apport-bug but it send the information to an already existing bug report. In my case it was apport-collect 1060268 Thanks to Brad Figg in Launchpad. Are there any other tools to report bugs?

  • Launcher icon differences in pixels between monitors usign same resolution

    - by Luis Alvarado
    Today I got to test a Samsung SyncMaster 2043nwx. My normal monitor was a 1080p Soniview TV that supports 1920x1080. I use 1680x1050 (16:10) as my common resolution. My amazed is when I see that the launcher icons looks more to a "correct size" of 32px to what they show in my Soniview where they actually take about 50% more using the same resolution. They are both the same resolution but in the Soniview the launcher icons look 50% bigger than the ones in the Samsung. My question is then, why the difference between both monitors since they are using the same resolution but are showing different launcher icon sizes.

  • MySQL Connector/Net 6.6.2 has been released

    - by fernando
    MySQL Connector/Net 6.6.2, a new version of the all-managed .NET driver for MySQL has been released.  This is the first of two beta releases intended to introduce users to the new features in the release.  This release is feature complete it should be stable enough for users to understand the new features and how we expect them to work.  As is the case with all non-GA releases, it should not be used in any production environment.  It is appropriate for use with MySQL server versions 5.0-5.6 It is now available in source and binary form from http://dev.mysql.com/downloads/connector/net/#downloads and mirror sites (note that not all mirror sites may be up to date at this point-if you can't find this version on some mirror, please try again later or choose another download site.) The 6.6 version of MySQL Connector/Net brings the following new features:   * Stored routine debugging   * Entity Framework 4.3 Code First support   * Pluggable authentication (now third parties can plug new authentications mechanisms into the driver).   * Full Visual Studio 2012 support: everything from Server Explorer to Intellisense & the Stored Routine debugger. Stored Procedure Debugging ------------------------------------------- We are very excited to introduce stored procedure debugging into our Visual Studio integration.  It works in a very intuitive manner by simply clicking 'Debug Routine' from Server Explorer. You can debug stored routines, functions & triggers. Some of the new features in this release include:   * Besides normal breakpoints, you can define conditional & pass count breakpoints.   * Now the debugger editor shows colorizing.   * Now you can change the values of locals in a function scope (previously caused deadlock due to functions executing within their own transaction).   * Now you can also debug triggers for 'replace' sql statements.   * In general anything related to locals, watches, breakpoints, stepping & call stack should work in a similar way to the C#'s Visual Studio debugger. Some limitations remains, due to the current debugger architecture:   * Some MySQL functions cannot be debugged currently (get_lock, release_lock, begin, commit, rollback, set transaction level)..   * Only one debug session may be active on a given server. The Debugger is feature complete at this point. We look forward to your feedback. Documentation ------------------------------------- The documentation is still being developed and will be readily available soon (before Beta 2).  You can view current Connector/Net documentation at http://dev.mysql.com/doc/refman/5.5/en/connector-net.html You can find our team blog at http://blogs.oracle.com/MySQLOnWindows. You can also post questions on our forums at http://forums.mysql.com/. Enjoy and thanks for the support!

  • Is it possible to only allow specific packages updates from a PPA

    - by Luis Alvarado
    Let us say I have added a PPA that has X package that I want but it also has Y package that I do not want to use or receive updates from. How can I, from the same PPA, receive updates for a specific package but deny updates from the same PPA for other packages. A step by step example would be good since this has happened to me in several PPAs that have a particular package I want but also add a whole bunch of others that I do not yet want to update.
