  • Dual monitor in Ubuntu 12.04 + Nvidia GPU with CUDA drivers?

    - by Aphex
    I'm thinking about setting up dual monitors on my desktop PC, running Ubuntu 12.04 with a Nvidia GTX 570. I use the GPU for CUDA programming so it's set up with the CUDA drivers. Is it possible/easy to set up dual monitors with this configuration? The only questions I saw related to this were for GPUs without cuda drivers. If anyone knows how dual monitors work with CUDA drivers, it would be much appreciated. It was enough of a pain getting everything running with the GPU and CUDA in the first place, I'd hate to ruin it all by attempting dual monitors.

  • Which programming language to develop software for USC that also runs on other OS?? (WINDOWS/OSX)

    - by Marian Lux
    I have skills in JAVA and C#: First i had a closer look to JAVA (Eclipse with Windowbuilder-Plugin) - Swing: But there is no natvie GUI-Support for GTK3 (e.g., HUD seems not to work) Then i was at JAVA - SWT: It is to heavy. I want do code a small app that improves the Ubuntu desktop. I don't want to ship a program with eclipse included. After that i found C# Mono (Monodevelop): GTK-shparp is only for GTK2 available. A GTK3-port will come soon but is it possible to convert the program from GTK2 to GTK3 without extra adaptations? The next bad thing is, that MONO is now dropped from Ubuntu LTS 12.04. So i have no chance that my app would be a default-app in an Ubuntu-Image. (This is also a factor for me to choose a programming language). I know there are other techs but i want to use as programing language JAVA or C#.

  • Xen 4.0.1 not booting with device not found error

  • Reviewing Retail Predictions for 2011

Alternate Payments We've seen several alternate payment schemes emerge over the last two years, and 2011 may be the year one of them takes hold. Any competition that can drive down fees will be good for everyone. I'm betting that Apple will add NFC chips to their next version of the iPhone, then enable payments in stores using iTunes accounts on the backend. Paypal will continue to make inroads, and Isis will announce a pilot. The iPhone 4S did not contain an NFC chip, so we’ll have to continuing waiting for the iPhone 5. PayPal announced its moving into in-store payments, and Google launched its wallet in selected cities.  Overall I think the payment scene is heating up and that trend will continue. 2. Engineered Systems The industry is moving toward purpose-built appliances that are optimized across the entire stack. Oracle calls these "engineered systems" and the first two examples are Exadata and Exalogic, but there are other examples from other vendors. These are particularly important to the retail industry because of the volume of data that must be processed. There should be continued adoption in 2011. Oracle reports that Exadata is its fasting growing product, and at the recent OpenWorld it announced the SuperCluster and Exalytics products, both continuing the engineered systems trend. SAP’s HANA continues to receive attention, and IBM also seems to be moving in this direction. 3. Social Analytics There are lots of tools that provide insight into how a brand is perceived across popular internet sites, but as far as I know, these tools are not industry specific. The next step needs to mine the data and determine how it should influence retail operations. The data needs to help retailers determine how they create promotions, which products to stock, and how to keep consumers engaged. Social data alone does not provide the answers, but its one more data point that will help retailers make better decisions. Look for some vendor consolidation to help make this happen. In March, Salesforce.com acquired leading social monitoring vendor Radian6 and followed up with acquisitions of Heroku and Model Metrics. The notion of Social CRM seems to be going more mainstream now. 4. 2-D Barcodes Look for more QRCodes on shelf-tags, in newspaper circulars, and on billboards. It's a great portal from the physical world into the digital one that buys us time until augmented reality matures further. Nobody wants to type "www", backslash, and ".com" on their phones. QRCodes are everywhere. ‘Nuff said. 5. In the words of Microsoft, "To the Cloud!" My favorite "cloud application" is Evernote. If you take notes on your work laptop, you will inevitably need those notes on your home PC. And if you manage to solve that problem, you'll need to access them from your mobile phone. Evernote stores your notes in the cloud and provides easy ways to access them. Being able to access a service from anywhere and not having to worry about backups, upgrades, etc. is great. Retailers will start to rely on cloud services, both public and private, in the coming year. There were no shortage of announcements in this area: Amazon’s cloud-based Kindle Fire, Apple’s iCloud, Oracle’s Public Cloud, etc. I saw an interesting presentation showing how BevMo moved their systems to the cloud.  Seems like retailers are starting to consider the cloud for specific uses. 6. F-CommerceTop of Form Move over "E" and "M" so we can introduce "F-Commerce," which should go mainstream in 2011. Already several retailers have created small stores on Facebook, and it won't be long before Facebook becomes a full-fledged channel in the omni-channel world of retail. The battle between Facebook and Google will heat up over retail, where both stand to make lots of money. JCPenney and ASOS both put their entire catalogs on Facebook, and lots of other retailers have connected Facebook to their e-commerce site. I still think selling from the newsfeed is the best approach, and several retailers are trying that approach as well. I just don’t see Google+ as a threat to Facebook, so I think that battle is over.  I called 2011 The Year of F-Commerce, and that was probably accurate. Its good to look back at predictions, but we also have to think about what was missed.  I didn't see Amazon entering the tablet business with such a splash, although in hindsight it was obvious. Nor did I think HP would fall so far so fast.  Look for my 2012 predictions coming soon.

  • Fullscreen windowed mode in id games

    - by Oli
    I run a TwinView, dual monitor system. I like to play games fullscreen on one of the monitors, not spanning both. With wine, this works by just setting it to desktop mode and setting the resolution to that of one screen. For OpenTTD, I used Compiz's Window Rules plugin. But I have a few native games that this doesn't work for. Today's experiment involved Prey (Doom 3 engine) but I've had similar issues with other ID engines. So in short: has anybody found a way of having Prey/OpenAreana/Doom3/etc run in windowed mode but with fullscreen decorations (that is to say, no borders and above the panel)?

  • Where can you find your first customers as a freelancer?

    - by Adam Smith
    I want to start doing freelance work, but no matter how I look at it, it seems like the best way to get customers and to have work most of the time, you have to already be in the freelancing game. Most freelancers I've talked to have had the same customers over the years or got new customers because their satisfied clients referred them. What I'd like to know from the successful people here that work as freelancers is how do you start doing business when you haven't yet set foot in freelancing? I want to start small, creating websites that won't require me to hire other people other than maybe a designer I already know. (I'd like to create desktop applications as well, but I think I should keep that for later when I'm more experienced) . I thought about localized Google ads or visiting companies and meeting the people in charge there, but I wouldn't know which kind of businesses to look for or if it's even a good way to approach this. Anyone care to share their personal startup experiences / advice that can help future freelancers?

  • Gmail Rolls Out New Compose Features

    - by Jason Fitzpatrick
    Gmail has several new features that make it even easier to compose email messages including pop-over compositions windows (similar to the Google Chat window), contact profile pictures in the address box, and drag and drop address switching. If you’ve ever had to open two separate windows in order to continually tab back and forth so you could reference one email while composing another, you’ll certainly appreciate the new pop-over compose window that allows you to work within Gmail while keeping a small email composition window open in the corner–as seen in the screenshot above. In addition to that major change, Gmail has also introduced contact photos in the address suggestion window (making it easier than ever to make sure you’re selecting the right recipient) and the ability to drag and drop addresses between the To:, CC:, and BCC: address slots.

  • Recommended installation for Asus EEE 1015PEM Netbook

    - by David B
    Hi, I just got my Asus EEE PC 1015PEM netbook with Windows 7 starter... obviously, I'd like to install Ubuntu (not sure yet if I'd like to dual boot or completely remove win7). Anyway, I never had a netbook before. I know about unity but heard some bad stuff about it, so I wonder if I might be better sticking to the desktop edition. What do you think? any recommendations? Also, should I use the 32 bit or 64 bit version?

  • Dual Screen with 12.04 ATI randr extension is not present

    - by Trevor Pearson
    Here's my problem I have two screens. One is a 22"led monitor and the other is 42 inch led tv. In windows 7 I run xbmc on the second monitor. I'm trying to mimic the same function in setting xbmc to display on the tv only. So I installed the latest x64 linux drivers from ATI. I configured (using the catalyst control panel) using single display (multi desktop) I then got a white screen with black x so I enable xinerama. with xinerama enable I got the displays to work correctly, however I received an error when I tried to enter display settings to change the launcher location. the error message was " "randr extension not present =" So I tried to install libxandr2 using terimal but here's what I get trev@Lrig:~$ sudo get-apt install libxander2 [sudo] password for trev: sudo: get-apt: command not found I'm at a loss now because I can't find a solution for the xandr error message.

  • Ultra-quick Samsung WebKit review

    On Thursday I got a Samsung bada test phone (the Wave) that runs the latest installment of Samsung WebKit, and of course I subjected it to various tests. The verdict is clear: excellent browser. As far as I’m concerned it ousts Opera Mobile from my personal top three.Judge for yourself. This is what the latest Samsung WebKit supports: It scores second, after Safari 4 for desktop, in my great WebKit test.

  • What's the best Wireframing tool?

    - by Strae
    I'm looking for something similar to iPlotz or Mockup. I've found the Pencil Project, but it requires xulrunner-1.9 (which seems to be incompatible with xulrunner-1.9.2) in order to run as a standalone application. It can be used as a firefox plugin... but it is a bit slower. The error on my desktop (Ubuntu 10.04) is: Could not find compatible GRE between version 1.9.1 and 1.9.2.* Does anyone know other software? Edit: Open-source software is preferred, and it doesn't matter whether or not it's free.

  • How can I mount an AFS filesystem?

    - by Ben
    My current method is to mount the filesystem via SSH using Nautilus's graphical interface, but I would much prefer to be able to use some tool that mounts the AFS filesystem and gives me access to AFS-specific features (permissions, etc.). I've tried installing OpenAFS via apt-get, but so far the kernel module has refused to compile. Also, assuming I get OpenAFS installed, I'm not quite sure how to actually mount the remote filesystem to, say, /media/afs or some directory. I'm running Maverick with the 2.6.36-020636-generic kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/ Thanks for the help!

  • EPM Architecture: Foundation

    - by Marc Schumacher
    This post is the first of a series that is going to describe the EPM System architecture per component. During the following weeks a couple of follow up posts will describe each component. If applicable, the component will have its standard port next to its name in brackets. EPM Foundation is Java based and consists of two web applications, Shared Services and Workspace. Both applications are accessed by browser through Oracle HTTP Server (OHS) or Internet Information Services (IIS). Communication to the backend database is done by JDBC. The file system to store Lifecycle Management (LCM) artifacts can be either local or remote (e.g. NFS, network share). For authentication purposes, the EPM Product Suite can connect to external directories or databases. Interaction with other EPM Suite components like product specific Lifecycle Management connectors or Reporting and Analysis Web happens through HTTP protocol. The next post will cover Reporting and Analysis.

  • Configure mounting timeout at boot

    - by René Pieters
    On remotely rebooting a 12.04 machine I found it hanging at the "unable to mount soandso: Skip, Manual Abort? " (That's pretty much how I remember the message) The machine was basically stopped there until I hooked up a keyboard and pressed "s". I can see the rationale for the question, but I'd really like to know where to configure it or turn it off altogether. A mandatory question like this makes sense in a desktop environment but for servers I'd like more flexibility. So where do I fiddle and tweak this?

  • How to prevent WLAN connection from dropping permanently on a Fritz USB WLAN N stick?

    - by Chris
    I have a desktop with a Fritz USB WLAN N stick and tried Ubuntu 12.04. Installation went fine and WLAN is working. However, connection drops permanent. Reconnecting manually fixes it but after a few minutes it drops again. It's connected to a Vodafone 802 box with WLAN N fix set. It seems that it works when I switch off N mode. But I need to test. Can someone confirm this issue or is there another solution? I have another machine with 12.04 (HP 625 laptop) running where connection is stable.

  • How to fix? Gnome-shell shows up and instantly stop working

    - by Dario
    I am using ubuntu 12.04, but I love gnome shell, but not the Gnome Classic which comes installed. When I reinstalled, I instantly installed Gnome-shell by terminal using Unity, it worked for a while and then I started installing some extensions. I rebooted and it just stopped working, it shows up for a second, then I can only see my desktop with icons but without panels and I can't even use the terminal (CTRL + ALT + T) since the window doesn't really select when I click it. How could I fix this? I tried reinstalling Gnome-shell and all the stuff I installed for it, but now it doesn't work even without any extension.

  • Looking for a light weight note program.

    - by Erin
    This might belongs on superuser but for me it's part of programming so i will ask it here. I find I use notepad to keep chunks of data that are important but not important enough to keep in my head. The one problem with this is I end up with a lot of files on my desktop that I don't know what they are for, or I don't save the file and my computer gets rebooted for some reason. So that big ramble leads to the question. I am looking for a note taking system that is light weight and easy to manage. I would rather it not be a huge application like onenote but if that is what you are using and is is working well for you could you explain how you are doing it? Thanks Erin.

  • Maximized Office 2007 gets cut off on multi-monitor setup with different resolutions

    - by Adam M-W
    I've got an external monitor plugged into my laptop that I like to use for typing up documents, but I've noticed that when Word is maximized it gets cut off at where the primary monitor's bounds are. Is this a bug in Wine (i'm using version 1.3.32), or with my Window Manager (metacity with compositing enabled, version 2.34.1), with my graphics drivers (nouveau) or something else? I know that I can fix it by unmaximizing (it doesn't get cut off and I can resize to the entirety of the second monitor), but it keeps on maximizing itself as it (rightly so) knows that it should be taking up the entire screen. I don't really want to use the "Emulate a virtual desktop feature", I would prefer to find the source of this issue.

  • SOA Suite 11g (11.1.1.3): Creating a single server domain with SOA Suite and Oracle Service Bus func

    - by Chris Tomkins
    One of the major benefits of the latest version of the Oracle SOA products, SOA Suite 11gR1 PS2 (11.1.1.3) and Oracle Service Bus 11gR1 (11.1.1.3), is that both products depend on the same version of WebLogic Server 11g (10.3.3) and so can be installed in the same domain. If you are a developer building artifacts for both but with a laptop/desktop with limited resources then this is particularly useful, as you can install a single server domain (by default you get a domain with an admin server and multiple managed servers) which incorporates both sets of functionality. The viewlet below shows you how to go about creating such a single server domain, using the configuration wizard. Just click the Play button from the viewlet menu to start it. Note: As you have added all this functionality into a single server, it will take a few minutes to start up. As this is my first foray into the world of viewlets I’d be interested in your opinion as to whether you have found this useful and any tips/techniques for improving any future viewlets I may create.
