  • Dumping a Linux console scrollback buffer?

    - by Gerald Combs
    We would like to save the output of a program run on a Linux console which spans many lines. Unfortunately it wasn't logged or run under screen, or any other way that lets us easily capture the output. The best method we've been able to come up with so far is: Log into the machine via a separate SSH session In the console session, page to the top of the buffer Repeat: In the SSH session, run "cat /dev/vcs >> screendump.txt" In the console session, page down one screen Dump the final screen in the SSH session Is there a better way? It seems like if the VC memory were contiguous and you knew where it was you could use dd to pull the console text directly out of kernel memory and into a file.

  • Assigning console.log to another object (Webkit issue)

    - by Trevor Burnham
    I wanted to keep my logging statements as short as possible while preventing console from being accessed when it doesn't exist; I came up with the following solution: var _ = {}; if (console) { _.log = console.debug; } else { _.log = function() { } } To me, this seems quite elegant, and it works great in Firefox 3.6 (including preserving the line numbers that make console.debug more useful than console.log). But it doesn't work in Safari 4. [Update: Or in Chrome. So the issue seems to be a difference between Firebug and the Webkit console.] If I follow the above with console.debug('A') _.log('B'); the first statement works fine in both browsers, but the second generates a "TypeError: Type Error" in Safari. Is this just a difference between how Firebug and the Safari Web Developer Tools implement console? If so, it is VERY annoying on Apple's Webkit's part. Binding the console function to a prototype and then instantiating, rather than binding it directly to the object, doesn't help. I could, of course, just call console.debug from an anonymous function assigned to _.log, but then I'd lose my line numbers. Any other ideas?

  • Artemis Is The Absolute Geekiest LAN Game You’ll Ever Play [Video]

    - by Jason Fitzpatrick
    Prepare to have your sense of what really geeky computer gaming look like with this Star Trek-like mockup that involves a projector, multiple monitors, and a crew of six. If you have five friends willing to pool some resources–because let us tell you, it’s not going to be cheap to build this gaming setup from scratch–you’re on your way to building a functional starship bridge in your rec room. You’ll need six computers and monitors, a projector to create the front-of-the-bridge-room effect, and a copy of the game–the full retail game is $40 but there is a free demo so you can take the starship simulation for a test spin. The base game is focused on simple simulations like defending your space station and fighting off waves of invaders, however, a recent update of the game supports user-created mission packs. The missions packs allow fans of the game to create intricate missions with objectives to expand the game much like fan-created RPG modules add game play value to table top role-playing games. Hit up the link below to read more about the game or just sit back and enjoy the entertaining video above of sci-fi bloggers manning a starship.

  • Play a Complete HTML5 Version of Super Mario Bros. Online for Free

    - by Akemi Iwaya
    If you love playing Super Mario Brothers, but hate the hassle of dealing with or setting up the game console, then you will be pleased to know a new and complete version is now available to play online. Josh Goldberg has worked hard to recreate the classic game in its entirety in HTML5, so sit back, relax, and get ready to enjoy all that Mario goodness via your favorite browser. There are three ‘modes’ of game play available: play through reproductions of the original classic levels, test yourself against randomly generated levels, or use the level editor to create custom levels. Special Note: There are two online versions available…one for playing in Google Chrome and one for playing in all other browsers. For our example we chose to use the non-Chrome version.

  • Cannot run "Automation Anywhere" exe files from console (session 0) on Windows Server 2003 64 bit

    - by Tyler
    I have a simple exe created from an Automation Anywhere task that displays a message box saying hello world. I created this simple exe just for debugging the following issue. When I log in to the console (session 0), and run the Automation Anywhere created executable, it starts to run the task, it shows up in the applications and processes list in the task manager and it shows the two "loading..." windows briefly on the screen, just like normal. But after that, nothing happens... the "hello world" message does not show up. The exe is done and is removed from the application and process list in the task manager. The user I am logged in as, has admin rights and the machine uses "autologin" to automatically log in using this profile when it starts up. If I right click on the exe and "run as" another admin user, the exe runs properly, showing the "hello world" message. Also, if I log into the server in a new session, with the original user (the one that has the problems in session 0), and then run the exe, it runs properly and shows the "hello world". It works fine in any session other than the console session. There is something about the console session that is causing the exe not to run properly... even though it does appear to start running the exe. I should also mention that everything was working fine until Monday at midnight, after which none of the executables could be run successfully. Nothing was changed on the server and no updates were installed. I have since installed windows updates, but that didn't change anything. Looking for some advice on how to get these executables working in the console session again. Thanks!

  • Web based console connections not working in Windows 7 posted: Jan 20, 2010 8:55 AM

    - by nmeth
    For slightly complicated reasons we tend to give people console access to VMs via the webui. This has worked fine in the past, however when the users update their client machines to Windows 7 (or Vista, I am told, although I have not tested that), then the console fails to work. On IE8, having allowed the ActiveX control, the tab causes a "Internet Explorer has stopped working" dialog. On Firefox 3.5 , once the plugin has been installed, using the console causes the browser to crash. I've updated to the most recent VC 2.5 release, and ESX 3.5u5. Anyone else seeing this? Any clues how to get round it (other than using the fat client). Nigel.

  • How to Play PC Games on Your TV

    - by Chris Hoffman
    No need to wait for Valve’s Steam Machines — connect your Windows gaming PC to your TV and use powerful PC graphics in the living room today. It’s easy — you don’t need any unusual hardware or special software. This is ideal if you’re already a PC gamer who wants to play your games on a larger screen. It’s also convenient if you want to play multiplayer PC games with controllers in your living rom. HDMI Cables and Controllers You’ll need an HDMI cable to connect your PC to your television. This requires a TV with HDMI-in, a PC with HDMI-out, and an HDMI cable. Modern TVs and PCs have had HDMI built in for years, so you should already be good to go. If you don’t have a spare HDMI cable lying around, you may have to buy one or repurpose one of your existing HDMI cables. Just don’t buy the expensive HDMI cables — even a cheap HDMI cable will work just as well as a more expensive one. Plug one end of the HDMI cable into the HDMI-out port on your PC and one end into the HDMI-In port on your TV. Switch your TV’s input to the appropriate HDMI port and you’ll see your PC’s desktop appear on your TV.  Your TV becomes just another external monitor. If you have your TV and PC far away from each other in different rooms, this won’t work. If you have a reasonably powerful laptop, you can just plug that into your TV — or you can unplug your desktop PC and hook it up next to your TV. Now you’ll just need an input device. You probably don’t want to sit directly in front of your TV with a wired keyboard and mouse! A wireless keyboard and wireless mouse can be convenient and may be ideal for some games. However, you’ll probably want a game controller like console players use. Better yet, get multiple game controllers so you can play local-multiplayer PC games with other people. The Xbox 360 controller is the ideal controller for PC gaming. Windows supports these controllers natively, and many PC games are designed specifically for these controllers. Note that Xbox One controllers aren’t yet supported on Windows because Microsoft hasn’t released drivers for them. Yes, you could use a third-party controller or go through the process of pairing a PlayStation controller with your PC using unofficial tools, but it’s better to get an Xbox 360 controller. Just plug one or more Xbox controllers into your PC’s USB ports and they’ll work without any setup required. While many PC games to support controllers, bear in mind that some games require a keyboard and mouse. A TV-Optimized Interface Use Steam’s Big Picture interface to more easily browse and launch games. This interface was designed for using on a television with controllers and even has an integrated web browser you can use with your controller. It will be used on the Valve’s Steam Machine consoles as the default TV interface. You can use a mouse with it too, of course. There’s also nothing stopping you from just using your Windows desktop with a mouse and keyboard — aside from how inconvenient it will be. To launch Big Picture Mode, open Steam and click the Big Picture button at the top-right corner of your screen. You can also press the glowing Xbox logo button in the middle of an Xbox 360 Controller to launch the Big Picture interface if Steam is open. Another Option: In-Home Streaming If you want to leave your PC in one room of your home and play PC games on a TV in a different room, you can consider using local streaming to stream games over your home network from your gaming PC to your television. Bear in mind that the game won’t be as smooth and responsive as it would if you were sitting in front of your PC. You’ll also need a modern router with fast wireless network speeds to keep up with the game streaming. Steam’s built-in In-Home Streaming feature is now available to everyone. You could plug a laptop with less-powerful graphics hardware into your TV and use it to stream games from your powerful desktop gaming rig. You could also use an older desktop PC you have lying around. To stream a game, log into Steam on your gaming PC and log into Steam with the same account on another computer on your home network. You’ll be able to view the library of installed games on your other PC and start streaming them. NVIDIA also has their own GameStream solution that allows you to stream games from a PC with powerful NVIDIA graphics hardware. However, you’ll need an NVIDIA Shield handheld gaming console to do this. At the moment, NVIDIA’s game streaming solution can only stream to the NVIDIA Shield. However, the NVIDIA Shield device can be connected to your TV so you can play that streaming game on your TV. Valve’s Steam Machines are supposed to bring PC gaming to the living room and they’ll do it using HDMI cables, a custom Steam controller, the Big Picture interface, and in-home streaming for compatibility with Windows games. You can do all of this yourself today — you’ll just need an Xbox 360 controller instead of the not-yet-released Steam controller.

  • Change Linux Console's Default Monitor

    - by Tim M
    Is there any way to specify which monitor the console is displayed on in Linux? Details: I have a 3 monitor setup with 2 video cards. When I boot the computer, the BIOS displays on the PCI graphics card (which has a small monitor). When starting Linux, the console is displayed on the same monitor. Is there a way to have the console output on a different monitor? I'm using the vesafb framebuffer. I don't see a way in my BIOS to change the default video card.

  • Configuring weblogic server console with external server urls, etc

    - by MeBigFatGuy
    there are obviously various 'canned' configuration options in oracle's weblogic server console for setting up data sources, jms queues, ldap servers etc, etc. What i want however is a way to configure other servers, mostly server urls, etc, in the console as well, and allow web applications running on the web server to access those configuration settings at runtime, probably through jndi names. Things like a document management server, a workflow server, etc. However I'm at a loss for how to configure custom jndi 'data sources' within wls' console. Is this possible?

I've tried to console.log(console); and got this functions below... assert: function assert() { [native code] } constructor: function Console() { [native code] } count: function count() { [native code] } debug: function debug() { [native code] } dir: function dir() { [native code] } dirxml: function dirxml() { [native code] } error: function error() { [native code] } group: function group() { [native code] } groupEnd: function groupEnd() { [native code] } info: function info() { [native code] } log: function log() { [native code] } markTimeline: function markTimeline() { [native code] } profile: function profile() { [native code] } profileEnd: function profileEnd() { [native code] } time: function time() { [native code] } timeEnd: function timeEnd() { [native code] } trace: function trace() { [native code] } warn: function warn() { [native code] } __proto__: Object [ I guess there's no way to clear up the console... but I wanted someone to say it to me... ]

  • Change default Console I/O functions handle.

    - by b-gen-jack-o-neill
    Hello. Is it possible to somehow change standart I/O functions handle on Windows? Language preffered is C++. If I understand it right, by selecting console project, compiler just pre-allocate console for you, and operates all standart I/O functions to work with its handle. So, what I want to do is to let one Console app actually write into another app Console buffer. I though that I could get first´s Console handle, than pass it to second app by a file (I don´t know much about interprocess comunication, and this seems easy) and than somehow use for example prinf with the first app handle. Can this be done? I know how to get console handle, but I have no idea how to redirect printf to that handle. Its just study-purpose project to more understand of OS work behind this. I am interested in how printf knows what Console it is assiciated with.

  • Is there a good host for console applications?

    - by Jamey McElveen
    We have several applications that run in AppHarbor that we are bringing in-house. Our worker processes for AppHarbor are developed as windows console applications. What is the best way to host these console application in house? Of course I can just install and run them but I am hoping for a more managed way to host them. I want them to restart if they fail, ability to run multiple applications. These are things that were managed by AppHarbor. Thanks

    I have a generalized program to be run both in windows and linux. When I run the program in the windows console it halts at a point where the .sh file is to be executed with a window popping asking for "which program to use" and requires manual intervention to cancel. My question is: How do I change the setting available in the console that will let not the execution to halt when an unknown file extension is encountered?

  • rundll32 gets stuck when running games on windows 7 [closed]

    - by Midhat
    When I run a game on my windows 7 laptop, Rundll32 completely uses up one of my cores and the game wont start. By searching the web I have been able to fix it by 1 - Disabling game info collection/updation from the games explorer. It solved the problem for some games but not all 2 - Killing the game exe once rundll32 gets stuck and restarting the game This has solved the problem for now, but is there a proper and permanent solution to this?

  • KVM Guest installed from console. But how to get to the guest's console?

    - by badbishop
    I'm trying to install a fully virtualized guest (Fedora 14 x86_64) on KVM (RHEL 6), using command-line only (both hypervisor and guest). It goes without errors, and without a tangible result . I'd like to know how to do a text-only installation. So, here's what I've done: # virt-install \ --name=FE --ram=756 --vcpus=1 \ --file=/var/lib/libvirt/images/FE.img --network bridge:br0 \ --nographics --os-type=linux \ --extra-args='console=tty0' -v \ --cdrom=/media/usb/Fedora-14-x86_64-Live-Desktop.iso Starting install... Creating domain... | 0 B 00:00 Connected to domain FE Escape character is ^] ÿ Now what? As I understand after googling for a couple of days, I should see the guest's output from the text installation, but nothing happens. virt-viewer cannot connect to it, kindly suggesting that I explore all the options by adding --help (which I did). If I reconnect with virsh, I see this: Domain installation still in progress. You can reconnect to the console to complete the installation process.

  • Games at Work Part 1: Introduction to Gamification and Applications

    - by ultan o'broin
    Games Are Everywhere How many of you (will admit to) remember playing Pong? OK then, do you play Angry Birds on your phone during work hours? Thought about why we keep playing online, video, and mobile games and what this "gamification" business we're hearing about means for the enterprise applications user experience? In Reality Is Broken: Why Games Make Us Better and How They Can Change the World, Jane McGonigal says that playing computer and online games now provides more rewards for people than their real lives do. Games offer intrinsic rewards and happiness to the players as they pursue more satisfying work and the success, social connection, and meaning that goes with it. Yep, Gran Turismo, Dungeons & Dragons, Guitar Hero, Mario Kart, Wii Boxing, and the rest are all forms of work it seems. Games are, in fact, work taken so seriously that governments now move to limit the impact of virtual gaming currencies on the real financial system. Anyone who spends hours harvesting crops on FarmVille realizes it’s hard work too. Yet games evoke a positive emotion in players who voluntarily stay engaged with games for hours, day after day. Some 183 million active gamers in the United States play on average 13 hours per week. Weekly, 5 million of those gamers play for longer than a working week (45 hours). So why not harness the work put into games to solve real-world problems? Or, in the case of our applications users, real-world work problems? What’s a Game? Jane explains that all games have four defining traits: a goal, rules, a feedback system, and voluntary participation. We need to look at what motivational ideas behind the dynamics of the game—what we call gamification—are appropriate for our users. Typically, these motivators are achievement, altruism, competition, reward, self-expression, and status). Common game techniques for leveraging these motivations include: Badging and avatars Points and awards Leader boards Progress charts Virtual currencies or goods Gifting and giving Challenges and quests Some technology commentators argue for a game layer on top of everything, but this layer is already part of our daily lives in many instances. We see gamification working around us already: the badging and kudos offered on My Oracle Support or other Oracle community forums, becoming a Dragon Slayer implementor of Atlassian applications, being made duke of your favorite coffee shop on Yelp, sharing your workout details with Nike+, or donating to Japanese earthquake relief through FarmVille, for example. And what does all this mean for the applications that you use in your work? Read on in part two...
