  • Slow Internet / Can't change brightness on 2010 Macbook AIr running 12.10 Ubuntu

    - by user103441
    The title really says it all. I haven't been able to change the brightness of my monitor since putting Ubuntu on it. I started off with 12.04 and then decided to see if 12.10 would fix the issue. The internet is also a fair bit slower than I am used to, especially when downloading. Apart from these two issues, everything goes very smoothly. If anyone could offer any advice or solutions, I would be very grateful.

  • WPF add c# code to customcontrol

    - by 0xDEAD BEEF
    I want to create simple custom control (derived from control and with look defined in generics.xaml). I need to change size of elements defined in generic.xaml, when control is resized! It would be great to write some of that generic.xaml part in C#. Is that possible? Or is there a way to create MVVM like custom control? What i am willing to create is simple blinking led control (on,blinking, off).

  • DNS propogation question with name server change

    - by Brian
    The registrar I have is networksolutions.com, and for quite a while, the name servers were pointing to Site5.com, where hosting is for one of my domains. I wanted to bring DNS control back to networksolutions, so I pointed the name servers back to networksolutions and added in all my A records. However, I noticed that the site soon became unreachable. I'm curious as to why this happened? If the domain was pointing to either the old name servers or the new ones, it would still have the proper A records and whatnot. Is this because when I changed name servers, a request was made to delete them completely, and then the DNS servers worldwide have to wait for network solutions to send out the new ones or something? I was hoping this would be a switch with zero downtime, such as a normal A record change.

  • Dual Control / Four Eyes Principle

    - by Ralf
    I have the requirement to implement some kind of Dual Control or Four-Eyes-Principle, meaning that every change of an object done by user A has to be checked by user B. A trivial example would be a publishing system where an author writes an article and another has to proofread it before it is published. I am a little bit surprised that you find nearly nothing about it on the net. No patterns, no libraries (besides cibet), no workflow solutions etc. Is this requirement really so uncommon? Or am I searching for the wrong terms? I am not looking for a specific solution. More for a pattern or best practice approach.

  • Location, Orientation, and Writing a Custom Control with Mono for Android, .NET, and C#

    - by Wallym
    Like real estate, mobile is about location, location, location. That means that direction is an important item. And just as important is how this information is presented to the user. In Nov. 2011, we talked about building a user interface in Mono For Android. In this article, I'll expand a little bit on that by creating a compass that displays north. We'll use Android's built-in sensor support to determine the orientation of the device, then use a custom control to display North. The output will look like

  • Oracle Database 11g Helps Control Exponential Data Growth

    - by [email protected]
    The 2010 ESG annual customer survey is now available. As part of it, ESG interviewed 300 customers about their IT priorities and, unsurprisingly, "Manage Data Growth" is top of the list. Perhaps less self-evident is the proposed solution to target this prime concern: "Often overlooked because it is a database platform, Oracle Database 11g offers additional capabilities such as automatic storage management (ASM), advanced data compression, and data protection that make managing data growth much easier for organizations of any size." The paper goes on to discuss these capabilities and highlights their potential benefits. Oracle Database 11g Helps Control Exponential Database Growth - a worthwhile read for anyone having to deal with rapidly increasing amounts of data. Download your free copy here.

  • Hack Your Lights for Remote Control

    - by Jason Fitzpatrick
    This clever hack combines a modified wall switch with unused buttons on a universal remote to create one-touch wireless control of the lighting in a media room. Andrew, the tinker behind this home theater hack, writes: I really liked the idea of controlling my “Home Theater” lights with a remote (TV or other), this would save me the exhausting task of heaving myself off the couch to turn the lights on or off. I found one of my remotes has a spare power button, its one of those stupid “universal” remotes that comes with DVD players or TVs but only work if you have all the same brand equipment, I don’t so this made a good option for a light switch.

  • How to control CPU frequency

    - by Tim
    I am using CPU Frequency Scaling Monitor 2.30.0 on the panel to show and control CPU frequency. My CPU frequency by default will change according to load. But I want to make CPU work at the lowest level and so I choose 800 MHz in CPU Frequency Scaling Monitor. After a few seconds, however, it automatically changes back to Powersave or Performance mode which has automatic adjustment to CPU frequency. I was wondering how to actually make CPU work at the lowest level? Thanks!

  • Cannot control the fan on a Sony Vaio laptop

    - by Xobb
    I've got Sony Vaio laptop and my fan is on all the time, though the temperature on the video-adapter is always over 60°?. As I've googled, vaiofand does not support VPC-EA series. Is there anything I can do with that or I need another laptop? I'm using the following graphics card: 01:00.0 VGA compatible controller: ATI Technologies Inc Manhattan [Mobility Radeon HD 5000 Series] though the problem is not with the graphics card. I've mentioned its temperature as the highest (64°C now btw). Seems like the notebook is always overheated and I cannot control the fan speed to make it cooler. And yes, I'm using the proprietary driver ATI/AMD FGLRX graphics driver. I'm using Kubuntu 11.04.

  • complex access control system

    - by Atul Gupta
    I want to build a complex access control system just like Facebook. How should I design my database so that: A user may select which streams to see (via liking a page) and may further select to see all or only important streams. Also he get to see posts of a friend, but if a friend changes visibility he may or may not see it. A user may be an owner or member of a group and accordingly he have access. So for a user there is so many access related information and also for each data point. I use Perl/MySQL/Apache. Any help will be appreciated.

  • AI control for a ship with physics model

    - by Petteri Hietavirta
    I am looking for ideas how to implement following in 2D space. Unfortunately I don't know much about AI/path finding/autonomous control yet. Let's say this ship can move freely but it has mass and momentum. Also, external forces might affect it (explosions etc). The player can set a target for the ship at any time and it should reach that spot and stop. Without physics this would be simple, just point to the direction and go. But how to deal with existing momentum and then stopping on the spot? I don't want to modify ship's placement directly. edit: Just to make clear, the physics related math of the ship itself is not the problem.

  • Cloud Control 12c: Verteilen von beliebiger Software mit Deployment Prozeduren

    - by Ralf Durben (DBA Community)
    Mit dem Lifecycle Management Pack von Oracle Enterprise Manager Cloud Control 12c können Sie Software aus der grafischen Konsole heraus auf Zielsysteme verteilen und installieren, also provisionieren. Dieses funktioniert für viele Oracle Produkte in einer vorgefertigen Form unter Verwendung von Deployment Prozeduren, die als eine Art Spezialformat für Provisionierungsskripte angesehen werden können. Dabei können die vorgefertigten Deployment Prozeduren direkt oder für die eigenen Bedürfnisse modifiziert verwendet werden. Sie können diese Technik jedoch auch für die Provisionierung beliebiger Software nutzen, indem Sie eigene Deployment Prozeduren erstellen. Als einfaches Beispiel einer solchen Provisionierung soll in diesem Tipp das Verteilen einer ZIP-Datei mit anschliessendem Auspacken betrachtet werden. Bewusst wird in diesem Tipp versucht, das Beispiel einfach zu halten, um einen leichten Einstieg zu ermöglichen. Dieser Tipp zeigt Ihnen, wie Sie eine ZIP-Datei mit einer selbstgeschriebenen Deployment Prozedur provisionieren können.

  • Remmina remote control: black screen after XBMC exit

    - by Tinellus
    I have a HTPC (Quietpc Sidewinder Fanless media pc) running Ubuntu 12.04 and autostarting XBMC Frodo. I'm remote controlling this machine using my laptop also running Ubuntu 12.04 and using Remmina VNC as a client. Everything works perfectly as long as XBMC is running: I can see the remote screen and control via mouse and keyboard on the laptop. However, when XBMC is stopped on the HTPC, my TV shows the Ubuntu desktop normally, but the screen on the laptop turns black. I'm however still controlling the HTPC since I can see the arrow moving upon laptop mouse movement, and I can still type text in the HTPC. Oddly, when the screensaver on the HTPC kicks in, I again have a visual on the laptop. Anyone any thoughts on this? What should I do to maintain visual after stopping XBMC? Any suggestions much appreciated. Thanks!

  • What happens at control invoke function?

    - by user65909
    A question about form controls invoke function. Control1 is created on thread1. If you want to update something in Control1 from thread2 you must do something like: delegate void SetTextCallback(string txt); void setText(string txt) { if (this.textBox1.InvokeRequired) { SetTextCallback d = new SetTextCallback(setText); this.Invoke(d, new object[] { txt }); } else { // this will run on thread1 even when called from thread2 this.textBox1.AppendText(msg); } }` What happens behind the scenes here? This invoke behaves different from a normal object invoke. When you want to call a function in an object on a specific thread, then that thread must be waiting on some queue of delegates, and execute the incoming delegates. Is it correct that the windows forms control invoke function is completely different from the standard object invoke function?

  • 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.

  • Qué control te gustaria?

    - by Jason Ulloa
    Cada vez, utilizó mas Jquery para enriquecer las aplicaciones que desarrollo, pero cada vez me doy cuenta de que siempre debo leer la documentación de los controles para poder recordar todas las funciones. Esto, sumado a la cantidad de código script que debo colocar en las páginas. Es por eso que decidi empezar a trabajar en una pequeña seríe de controles de Jquery para asp.net basado en el framework DJ Jquery. Por supuesto, una serie de controles OpenSource para la comunidad   Actualmente los controles disponibles son: * Accordion * Animation * Autocomplete * DatePicker * Dialog * Draggable * Droppable * Effect * FileUpload * FlexGrid (en desarrollo) * Floater Menu * JMenu (en desarrollo) * Jquery Plugin * Password Meter * ProgressBar * Resizable * Selectable * Slick Menu * Slider * Sortable * Tabs * ButtonEx * Toggle Button * Simple Button * Simple List View   Así que la idea es preguntarles: ¿Qué otro control les gustaría ver en la suite?   Saludos,
