• Intel HD 4000 and Nvidia GT 650 working together on laptop

  - by Juan

  My new win7 Acer notebook has i5 CPU with Intel HD 4000 and Nvida GT650 GPU. Obviously monitor is plugged to Intel HD. In Nvidia control panel I can configure PhysX but that doesn't help. Windows system rating shows high gaming experience and average/low windows aero experience. What does that mean? Does my laptop use nvidia for games/3d apps nad Intel HD 4000 for aero? Should I disable Intel HD in bios, but how to plug monitor to nvidia? Or should I leave everything like now because everything works as it suppose to work? Here is image capture of some states: http://oi47.tinypic.com/34p0qp4.jpg

• Cross platform KVM over ethernet

  - by Falmarri

  I'm not sure if this exists, but this is what I'd like to do. I have a laptop and a desktop that I work on about equally. The laptop runs windows 7 and the desktop is on kubuntu 10.04. What I want to be able to do is be able to drag my mouse accross my screen and have it act like my laptop is a second monitor. Whereby I can use my desktop mouse, drag it say to the left off of my desktop monitor, and use it on my laptop (I don't care about the keyboard, just the mouse). Is that possible? Are there any other solutions that exist? I'd prefer not to have a physical kvm switch.

• "Automatic" class proxy in C++

  - by PierreBdR

  I need to allow the user to change members of two data structures of the same type at the same time. For example: struct Foo { int a, b; } Foo a1 = {1,2}, a2 = {3,4}; dual(a1,a2)->a = 5; // Now a1 = {5,2} and a2 = {5,2} I have a class that works and that change first a1 and then copy a1 into a2. This is fine as long as: the class copied is small the user doesn't mind about everything being copied, not only the part modified. Is there a way to obtain this behavior: dual(a1,a2)->a = 5; // Now a1 = {5,2} and a2 = {5,4} I am opened to alternative syntax, but they should stay simple, and I would like to avoid things like: set_members(a1, a2, &Foo::a, 5); members(a1, a2, &Foo::a) = 5; or anything involving specifying explictely &Foo::

• Order of declaration in an anonymous pl/sql block

  - by RenderIn

  I have an anonymous pl/sql block with a procedure declared inside of it as well as a cursor. If I declare the procedure before the cursor it fails. Is there a requirement that cursors be declared prior to procedures? What other rules are there for order of declaration in a pl/sql block? This works: DECLARE cursor cur is select 1 from dual; procedure foo as begin null; end foo; BEGIN null; END; This fails with error PLS-00103: Encountered the symbol "CURSOR" when expecting one of the following: begin function package pragma procedure form DECLARE procedure foo as begin null; end foo; cursor cur is select 1 from dual; BEGIN null; END;

• Do I have a bad video card?

  - by zooropa

  I think this is the right spot to post this question. Please don't flame me if it isn't. My work computer is a Dell Prescision M6400 laptop. I use the VGA output to a second monitor. There is something wrong with my second monitor's output. Here is a screenshot of my desktop. You can see fragments of the right side of a Windows File Explorer window in the image. Is this a bad video card?

• Multiple Windows Desktop areas for Full-Screen applications

  - by arootbeer

  Is it possible to run multiple instances of Windows Explorer within a single user session, or configure multiple desktops that are portions of a screen? I don't know the best way to describe what I want to achieve, but here's a picture of what I've got: I've got a 4 monitor setup, 3 portrait and one landscape, and I am normally running a number of RDP sessions, outlook, chrome, a development environment or two, so on and so forth. Most of these applications support full-screen views which mostly or completely hide the window borders, but on the Windows Desktop they take up a full monitor to do so. What I want to do is have 7 "desktops", "regions", call them what you will, each of which is, for the purposes of applications running in it, a "full screen" environment: I'm not tied to Windows Explorer for this, in case it helps - a different window manager that will support this functionality would be a perfectly acceptable answer.

• Windows Remote Desktop with multiple monitors

  - by BDW

  I'm looking for a remote desktop product that will allow me to switch on the fly between how many monitors the desktop is using. This would be going from one Windows 7 machine to another, one is running Ultimate, the other Enterprise. I know I can use Windows RDP with multi-monitor support, but it seems that only allows me to use ALL monitors, and if I switch to a windowed view, I get huge scrollbars because I'm going from 3 monitors to 1 window. What I'm looking for is something that will allow me to switch from 1, 2, or 3 monitor displays without restarting the RDP and would end up with a true 1/2/3 display - ie, if I go from 3 monitors to 1, or a window, I don't get scrollbars. Is there any such product?

• Is GPU active when there are not any monitors?

  - by Mixer

  Does GPU render anything when there is no monitor plugged in? Today I turned my old PC into some kind of a "server" which means that I want it running 24/7. I don't need any display (I will operate through ssh) so when everything was set up I removed my monitor. After a hour I checked my graphic card's cooling system and it was still hot. My graphic card is GeForce 8600 (with DVI connector), OS is Debian Linux. What is the best solution in this situation (standalone server) if GPU is active and I don't want it to waste power?

• C# Alternating threads

  - by Mutoh

  Imagine a situation in which there are one king and n number of minions submissed to him. When the king says "One!", one of the minions says "Two!", but only one of them. That is, only the fastest minion speaks while the others must wait for another call of the king. This is my try: using System; using System.Threading; class Program { static bool leaderGO = false; void Leader() { do { lock(this) { //Console.WriteLine("? {0}", leaderGO); if (leaderGO) Monitor.Wait(this); Console.WriteLine("> One!"); Thread.Sleep(200); leaderGO = true; Monitor.Pulse(this); } } while(true); } void Follower (char chant) { do { lock(this) { //Console.WriteLine("! {0}", leaderGO); if (!leaderGO) Monitor.Wait(this); Console.WriteLine("{0} Two!", chant); leaderGO = false; Monitor.Pulse(this); } } while(true); } static void Main() { Console.WriteLine("Go!\n"); Program m = new Program(); Thread king = new Thread(() => m.Leader()); Thread minion1 = new Thread(() => m.Follower('#')); Thread minion2 = new Thread(() => m.Follower('$')); king.Start(); minion1.Start(); minion2.Start(); Console.ReadKey(); king.Abort(); minion1.Abort(); minion2.Abort(); } } The expected output would be this (# and $ representing the two different minions): > One! # Two! > One! $ Two! > One! $ Two! ... The order in which they'd appear doesn't matter, it'd be random. The problem, however, is that this code, when compiled, produces this instead: > One! # Two! $ Two! > One! # Two! > One! $ Two! # Two! ... That is, more than one minion speaks at the same time. This would cause quite the tumult with even more minions, and a king shoudln't allow a meddling of this kind. What would be a possible solution?

• Tool for monitoring windows processes and folders

  - by Stoimen

  I am looking for a tool that tracks and keeps information for some processes on windows how long they've been running, when they have had started/closed. Also it would be nice to monitor folders if some data have been added/deleted to them. This is basically what I need. I tried Process Monitor but it gave me too much information. Just for creating a new folder it lists tons of useless information. I just need the time of creation... I tried and Process Explorer but it doesn't fit my needs either because it shows only the current state of my PC but I need to run some processes for couple of hours and after that to check what went wrong but unfortunately no records are saved.

• Using the "IN" clause with a comma delimited string from the output of a replace() function in Oracle SQL

  - by Thomas

  Hi All, I have an comma delimited string which I want to use in an "IN" clause of the statement. eg: 100,101,102 Since In and "IN" clause I have to quote the individial strings, I use a replace function: eg: select ''''||replace('100,101,102',',',''', ''')||'''' from dual; The above query works, however, when I try to use the output of the above as an input to the "IN" clause, it returns no data. I am restricted by only SQL statements, so I cannot use PL/SQL code. Kindly help. eg: select * from employee where employee_number in ( select ''''||replace('100,101,102',',',''', ''')||'''' from dual); The above does not work. Please let me know what I am missing.

• How to temporarily disable SonicWall from connecting to the internet?

  - by Jerry Dodge

  I have been doing some extensive seeking in our SonicWall TZ-215 for the source(s) of unnecessary internet traffic, as we have issues with excessive traffic. As part of my research, I need to watch the Connections Monitor, which lists me all the current connections. This list becomes quite long, with 40+ devices on the network, it's tough to pinpoint the main causes. What I would like to do is disable the SonicWall its self from letting its internal components from connecting to anything. Is there any type of trick I can do in the Firewall which can prevent the router system from connecting to anything, to clean up the connections monitor and allow only suspicious traffic?

• How I can be alerted if an application is not running in Windows 2008 R2?

  - by Magnetic_dud

  I have a critical application that I need to have it running on my server. Unfortunately it's poorly coded and it keeps crashing. If it's not running it's a big problem, but I can't use a simple application monitor like this because if the app crashes I need to input the configuration again - so I can't just run it again, I have to RDP into the server and manually start it again. So I need a monitor that sends me an email if the process has been stopped. Anyone knows a program that can do that job? I couldn't find it

• Automated monitoring of a remote system that sends email alerts.

  - by user23105

  I need to monitor a remote system where the only access I have is that I can subscribe to email alerts of completed/failed jobs. I would like a system that can monitor these emails and provide an SMS or other alert when: An email indicates failure. A process that was expected to complete by a given time has not. A process that was expected to complete N minutes after completion of another process has not completed. Are there any existing tools that allow this? I'd consider any option - SaaS, open-source, COTS, as long as I don't have to write it myself! Cheers, Blake

• Can't get to the login screen

  - by Rod

  I upgraded my wife's Windows 7 machine, to Windows 8 Pro, about 10 days ago. She's been using it fine ever since. We typically leave our desktops running 24/7, and just turn off the monitor. This morning she turned the monitor on, and saw the screen with the Seattle Space Needle, and then she pressed the enter key to get to the login screen. Nothing happened. Next she pressed the mouse key. Nothing happened. The mouse moves around fine. But we can't get it past the Seattle Space Needle screen. She replaced the batteries in both her keyboard and mouse recently. So, what's going on? How do we fix it?

• Are there any open-source simple network monitoring applications? [duplicate]

  - by scottm

  This question already has an answer here: What tool do you use to monitor your servers? 73 answers I am debugging a problem with one of our systems. Every Sunday, it stops communicating with another server. If we reboot both servers, communication works again. I was wondering if there are any small footprint apps that monitor TCP port availability and network connectivity, possibly logging any downtime. I'd also like it to be open source if possible, but if there is another solution that is proprietary, I'd like to hear about it also.

• perfmon.exe itself taking 52.71% of cpu on windows 7 after chrome dies?

  - by jamesmoorecode

  On my Windows 7 machine (build 7100, x64, Dell XPS M1710 laptop), I'm getting horrible performance after chrome crashes. I kill the chrome process from the Resource Monitor, but after that perfmon.exe itself is shown as taking about 50% of the cpu (52.31% right now). Quitting Performance Monitor, then starting it again, shows perfmon starting out with a reasonable CPU, but it quickly (ten seconds) shoots right back up. Suggestions? So far a reboot seems to be the only way to solve the problem. I'm assuming that the perfmon issue is just a symptom of the real problem. (Update, much later: this never got resolved. I'm not seeing the problem in the RTM Win7 + latest Chrome. Yes, it was a core 2 duo, so presumably Chrome was running full blast on one cpu.)

• Cannot connect my Ubuntu to TV with HDMI

  - by Hannes Johannes

  Another problem in my way to Ubuntu world.. Trying to make things work Linux way, day 4, problem #5321: I have a Compaq laptop and Nvidia graphic adapter. I also have Panasonic TV, which I thought I could use as a second screen just like I used to to when I was still using Windows Vista with my laptop. Plug the screen to the comp and voilá, I can watch my videos on big screen. And a boll***s I can, not with ubuntu anyways. Nvidia x server (or whatever it's called) does recognize my tv. It's very badly designed gui as I can never be sure has it saved my changes or not (most often not), but I recon I've got that one sorted out. I haven't found a way to set a primary monitor there, but it does see there are two monitors, my laptop and the tv. So far so good. But then? Ubuntu's own monitor setting only sees the laptop screen. If I reboot (with the HDMI cable connected) I end up having a black screen. Then I have to take the cable away, cut the power off and restart the comp.. Please, help, any help would be appreciated! I would so much love to like this linux more than windows but it surely takes a lot of trying...

• Troubleshooting SQL Azure Connectivity

• xvidcap: Error accessing sound input from /dev/dsp

  - by stivlo

  I'm running Ubuntu 11.10 and I'm trying xvidcap to record a screencast with audio from the microphone, however it can't record any sound: $ xvidcap --file appo.avi --cap_geometry 700x500-0+0 Error accessing sound input from /dev/dsp Sound disabled! Sure enough /dev/dsp doesn't even exist: $ sudo ls -lh /dev/dsp ls: cannot access /dev/dsp: No such file or directory I found a blog post about fixing xvidcap sound input, however if I try the suggestion I get: $ sudo modprobe snd-pcm-oss FATAL: Module snd_pcm_oss not found. So the question is, how can I create /dev/dsp? The problem behind the problem is: how can I record sound from the microphone with xvidcap? So workarounds are welcome too. UPDATE: I've followed the suggestion of James, and something has improved. The error accessing /dev/dsp is gone, however now I get: [oss @ 0x8e0c120] Estimating duration from bitrate, this may be inaccurate xtoffmpeg.c add_audio_stream(): Can't initialize fifo for audio recording Now when I record xvidcap appears in the recording tab of pavucontrol and I can choose Audio stream from Internal Audio Analog Stereo or Monitor of Internal Audio Analog Stereo, I tried both just in case, but the video is still mute. UPDATE 2: I found that "Monitor of" is the one to record application sounds, while for microphone, I should choose "Internal Audio Analog Stereo". To rule out other problems, such as with the microphone, I tried with gnome-sound-recorder and it works. Actually I jumped on my chair, since the volume was too high! :-)

• JMX Based Monitoring - Part One

  - by Anthony Shorten

  In all versions of the Oracle Utilities Application Framework there is an ability to use Java Management eXtensions (JMX) to both manage and monitor the various components of the product. This means that sites can use a JSR120 compliant JMX browser or JMX console to view or manage the components of the product with little or no configuration required. In each version we have progressively added JMX capabilities to allow IT groups more detailed information. In Oracle Utilities Application Framework V2.1 and above it was possible to use JMX on the Web Application Server provided Mbeans to allow you to monitor the online component of the product as well as manage the configuration. Also with a few additional java options it is possible to get a good level of detail about the Java Virtual machine including memory and thread usage. In Oracle Utilities Application Framework V2.2 and above, we added support for Java 5 statistics (Java enabled them by default), database pool statistics and also added the ability to manage and moinitor the batch component of the architecture. Now, in Oracle Utilities Application Framework V4 and above, we added support for Java 6 MXBeans, online management of the cache using JMX, additional JVM information and Performance monitoring using JMX. JMX allows the product to be managed from a common console such as Oracle Enterprise Manager, Tivoli, HP OpenView (and a lot more). Over the next week or so I will be compiling a set of blog entries discussing what is available (in summary format) using JMX and how to get access to the JMX statistics for your version of the product.
