• Broadcasting webinars to and from Ubuntu

  - by Chris Wilson

  I've recently attended an online workshop using Citrix GoToWebinar, a service that allows someone to broadcast their desktop and audio out to all members connected to the presentation as well as receive audio and screencasts from those attendees , and the experience was unbelievable, and I was wondering if there was any such service/software available on Ubuntu. Points to consider include, but are not limited to: Web services or local applications. Free (as in beer) or paid. Free (as in speech) or proprietary. Ease of use Ease of setup Any other point that anyone can thing of

• Canon MP280 All in One prints but scanner not recognized

  - by Chris

  I recently installed Ubuntu 12.04 LTS after not using any Linux distro for several years. My Canon MP280 worked perfectly as far as printing goes and I was even able to set it up on a Samba share and print from a Windows 7 machine. However when I open Simple Scan it does not detect a scanner. I did find some instructions online but the scanner is still not recognized in Simple Scan even after installing a couple .deb packages from the Canon site. I also couldn't seem to find the ScanGear package after installing those .deb packages as well but I haven't had a chance to delve fully into it. Thanks for your time!

• How do I read my PDFs and watch videos properly again?

  - by asp

  Whenever I watch videos, either online of local via Totem and/or open PDF files using evince. The system gets really, really bogged down. All apps get really slow, menus take forever to display, switching windows gives me time to make a coffee, etc. I have a couple of bug reports open on this, but what do I need to do to really troubleshoot the issue? I've purged Adobe Flash from the system, but YouTube HTML5 videos still have the issue. A bunch of PDFs saved locally trigger the problem. And to (temporarily) remove the slowness, I need to shutdown the computer, breath for a few minutes, then restart. A simple reboot does not do the trick. How can I identify the cause? This only started on 13.04. I've had Ubuntu on this machine for a year without a problem until "upgrading" to 13.04. I am not a programmer, but I suspect an issue with the Intel video driver.

• Is HTML5 more secure to develop for than Silverlight?

  - by King Chan

  I'm learning Silverlight, and I know that if I master it, I can apply the same concepts to WPF, which means I can do either web or desktop development pretty easily. But I've read articles and followed the discussion online, and I understand HTML5 is gaining traction for being cross-platform, and a lot of people seem to be moving to HTML5. From my understanding, any HTML5 application would be built with HTML and JavaScript (or Flash). But is it secure? It seems like anyone can easily use their browser's "view source" option and grab your code. Is this something I should be worried about, or is there a way to protect against it?

• Communications: Customer Experience

  - by Michael Seback

• Optimus Bumblebee Performance

  - by Chance

  After installing Ubuntu 12.04 and Bumblebee, I tested out the performance of the Nvidia card using Minecraft and a few other games. I've noticed it to be way slower than it was on Windows 7. Is this normal? I'm using the GT 630m. From what I've read online, nobody has said it to be slower than Windows. I'm just really curious because I want to use Linux so much more than Windows, but if I don't get the same performance I feel really picky. The Nvidia card is still faster than my Intel graphics on Ubuntu, but it's not as fast as it was for my on Windows. I get 60 - 80 fps on Minecraft on windows, while I get 28 - 48 fps on Ubuntu. Any Ideas why? Thanks so much!

• Should I Learn C/C++ Even If I Just Want To Do Web Programming?

  - by Daniel

  My goal is to be able to create online apps and dynamic, database driven websites. For instance, if in the future I get the idea for the next Digg or Facebook, I want to be able to code it myself. To arrive there I think I have basically two paths: Path 1 Start at a basic level, learning C, then C++ for OOP, then algorithms and data structures, with the goal of getting a solid grasp of computer programming. Only then move to PHP/MySQL/HTTP and start working on practical programming projects. Path 2 Start directly with PHP/MySQL/HTTP and getting my hands dirty with practical projects right away. What would you guys recommend?

• How do I create a big multiplayer world in UDK?

  - by Dorpe

  I want to create a big multiplayer world in UDK and I'm having a few difficulties. I created the biggest terrain possible but then any terrain related action I do takes forever. However, I've seen videos of people make same size terrain and working without a problem. My pc is strong enough, so maybe someone can tell me what I'm doing wrong. I want to make it even bigger then the biggest terrain size, so I was thinking of doing level streaming but then I read that streaming is working server side which means if I have a player on every terrain all terrains will still be loaded and I want to save as much memory possible so it will work well online. Thanks for any help you can give.

• Backing up VPS and Database Servers for website

  - by TravisK

  I currently have an "un-managed" (no help from hosting company) windows vps server. I am working on a good backup solution to return my site back online within a few hours. I am pretty comfortable backing up and restoring my database, however what is a good solution for backing up my VPS for easy recovery? Should I just use windows backup and create an image? I'm open to suggestions. Additionally, has anyone had to restore an entire VPS before? Is it reasonable to have it back up and running in a few hours?

• 24h dans la vie d'Internet, une infographie réalisée par de jeunes chercheurs et designers dévoile des chiffres surprenants

  24h dans la vie d'Internet Une infographie réalisée par de jeunes chercheurs et designers dévoile des chiffres surprenants Jen Rhee et l'équipe du site MBA Online (le site d'auto-formation et de conseil qu'il a créé) ont réalisé une infographie pour le moins surprenante. Ils se sont intéressés à ce qui se passe sur Internet en l'espace d'une simple journée. Et les chiffres révélés sont à la fois étonnants et amusants. On y apprend par exemple qu'en une journée, les flux d'informations échangés sur Internet pourraient remplir 168 millions de DVD. Que près de 294 milliards d'e-mails sont envoyés (l'équivalent de deux années de traitement de courrier aux Etats-Unis). Ou que 2 millions d'articles de ...

• Should I understand SVN before I jump to GIT?

  - by John Isaacks

  I work in a department where no one has ever used source control before, including myself. I am trying to push the concept. I have spent a little while researching SVN. I some basics learned. I can Create/update/checkout/commit with command line and from Tortoise. I am starting to learn how to tag and branch but still confused a lot about conflicts between branches and trunk etc. I am still learning, but I do not have a physical person who can show me anything. Its all from books/tutorials and trial and error. From what I have read online it seems like git is the better thing to know, but its also more complicated. I don't want to overwhelm myself. Should I continue to master svn before moving to git or would I be wiser to just jump to git now? Are there pros and cons to both approaches?

• OpenWonderland goes to Europe

  - by user12652314

  Past my day job, I also have the privilege of being Vice President and Member of the Board of the OpenWonderland Foundation (Formerly Project Wonderland for ex-Sun folks). It's great to see the progress Wonderland is making as the platform-of-choice for open source collaborative 3-D virtual worlds built in Java. The upcoming and first european IE Summit in Madrid will show a number of projects and innovations for virtual and game-based learning. I also dropped Ultan a note after learning about the Gamification of Oracle Apps to see if collaborating with kids and schools is an area we can work together on to improve kids engagement and learning experiences online. Stay tuned.

• Syncing WM6 <-> Evolution.... opensync-module-python missing?

  - by luri

  I'm trying to install opensync-plugin-synce to sync my wm6 phone with Evolution, but when I try (from synaptic, also with ap-get), is: Depende: opensync-module-python but it is not installable In fact, I haven't found opensync-module-python in repositories. Any hint? Is there any way to sync WM6 and Evolution (preferably without intermediate online syncs as Gmail, for instance)? Update: opensync-module-python exists in the repositories for previous versions of Ubuntu (mine is 10.10).... could I install it from there or would I ruin something? Update: should I mark this as impossible? Seems to be no way to sync WM6 phone with Evolution right now....

• What is a modern software engineer's resume supposed to look like? [on hold]

  - by willOEM

  My secondary education was primarily focused on the sciences (Molecular Biology and Bioinformatics), but now I work primarily as a software developer. I feel like my resume is totally inappropriate for my current career goals. Listing laboratory skills and accomplishments is not the same as listing software development skills and accomplishments. Oddly enough, I can't seem to find any resources for writing a engineer's resume online that aren't older than 5 years. GitHub and StackExchange profiles seem like as important resume items as anything, yet I don't know how to list them on a resume, or whether they are appropriate at all. So what is a modern software engineer's resume supposed to look like?

• Will the Global Demand for Water Outstrip the Supply by 2030?

  - by Evelyn Neumayr

  A recent study conducted by the Economist Intelligence Unit and sponsored by Oracle Utilities, titled “Water for All?”,considers the preparedness of utilities to supply water to the current global population of over 7 billion people, with a further 1 billion expected by 2030. It compares strategies used by utilities in 10 major countries to address this challenge. This study’s findings show that wide-ranging water management efforts and large-scale investments must be made if utilities are to meet near-certain water stress—demand outstripping supply—by 2030. The report is based on an online survey of 244 executives of water utilities in these countries, supplemented by in-depth interviews with 20 water utility executives and independent experts. The research concludes that utilities worldwide expect to meet future demand, despite increased supply pressure on supplies, due to improvements in water productivity that the wide range of measures utilities and governments will take to ensure that water is used more efficiently.

• Is it me, or is it you? Does the sync work?

  - by bisi

  I have been on this for several hours now, trying to get a simple second folder to sync with my (paid) account. I cannot tell you how many times I removed all devices, removed stored passwords, killed all processes of u1, logged out and back in online...and still, the tick in the file browser (Synchronize this folder) is loading and loading and loading. Also, I have logged out, rebooted countless times. And this is after me somehow managing to get the u1 preferences to finally "connect" again. I have also checked the status of your services, and none are close to what I am experiencing. And I have checked the suggested related questions above! So please, just confirm whether it is a problem on my side, or a problem on your side.

• How do I implement URL rewriting in my .htaccess file?

  - by Alan

  I'd like to do some URL rewriting (Why? See this question.) so that instead of users seeing addresses like labouseur.com/course-compilers.html they can instead see and use simply labouseur.com/course-compilers (Even better, maybe I should restructure that so that it's courses/compilers.) I'm using a Linux-based shared hosting service for my website, so I do not have administrative control of the server, but I do have control over .htaccess. The references I've read online seemed less than clear to me, so I'm looking for a little clarity and advice here. Thanks!

• YouTube fullscreen not displaying

  - by pt2ph8

  For some reason YouTube videos in my website do not get the fullscreen button, even if I added the parameter allowFullScreen set to true both in the object and embed tag. Here's an example page: http://www.indievault.it/2011/11/09/indie-vault-alla-games-week-2011-online-la-video-gallery/ Just take a quick look at the source. The allowFullScreen param is there, but the button won't show. Here's an excerpt from the code in that page: <object width="540" height="325"><param name="movie" value="http://www.youtube.com/v/dvYQhJwwkgA"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/dvYQhJwwkgA" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="540" height="325"></embed </object>

• Is there a simple shopping cart I can add to my existing website?

  - by Kalessin

  I created a website for my wife, who knits scarves. The site simply displays the 18 different colours she has created, with a Lightbox-like large photo available when clicked. She would now like to give visitors the option to purchase online and pay with PayPal and possibly Google Checkout. We do not need a full ecommerce solution; I've looked at several and they all seem to be overkill for our requirements. We don't even need categories. "All" I want is something that will add products to a cart, take the customer details and integrate the payment provider. So far, the best solution I have found seems to be this script on Codecanyon and I wanted to find out if anyone knows of any better products before I commit to this route. Thanks for your help!

• On-Premises to Office 365: Identity

  - by Sahil Malik

  SharePoint, WCF and Azure Trainings: more information “Run your business, not your mail server.” I am not sure where I read that, but it makes so much sense! Every organization is moving to the cloud, and some just haven’t started their journey yet. One of the fastest and most compelling online cloud based offerings is Office 365. Available in various SKUs, you can get SharePoint, Lync, Exchange, and Office professional as cloud-based offerings. The subscriptions are as low as $2 per user per month to $20 something per user per month. Also, with SharePoint 2013, if you buy Office 365 subscriptions for your users, you don’t need to buy CALs (Client Access Licenses) for on-premises use. Read full article here.
