  • Google Chrome Won't Open

    - by Mike Strand
    When I try to open Google Chrome from the launcher, nothing seems to happen. (this is a new phenomenon, it used to work). I'm on Ubuntu 13.04. When I try to open via the terminal with either $ google-chrome $ google-chrome --incognito I get, ":FATAL:zygote_host_impl_linux.cc(138)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /opt/google/chrome/chrome-sandbox is owned by root and has mode 4755." Any help would be appreciated.

  • Chrome and Catalyst - no tab text

    - by Martin Fejes
    I just installed Ubuntu, updated, installed AMD proprietary drivers (for my Radeon HD6870) and noticed that some (most) of the tabs in Google Chrome don't have text, only the favicon. My first idea was that maybe 13.10 may have some issues with the new drivers so I switched to the normal driver instead of the beta one. It was not good. Okay then, I put back the open source drivers. It worked. Okay, it's strange. Let's install Ubuntu Gnome to see if it's Unity. No it was not. Let's install Ubuntu 13.04. Same behavoir. By this time I was desperate. I installed Fedora, the problem was there. Now I'm back to Ubuntu 13.10, but am out of ideas. Could anyone help me, please? P.s.: I can upload a screenshot, if needed.

  • Good Literature for "Object oriented programming in C"

    - by Dipan Mehta
    This is not a debate question about whether or not C is a good candidate for Object oriented programming or not. Quite often C is the primary platform where the development is happening. I have seen, and hopefully learnt through crawling many open source and commercial projects - that while the language inherently doesn't stop you if you create "non-object" code. However, you can still think in the "Object" way and reasonably write code that captures this designs thinking. For those who has done this, OO way is still the best way to write code even when you are programming in C. While, I have learnt most of it through the hard way, are there any deep literature that can help educate the relatively young guys about how to do OO programming in C?

  • How to auto-scan any plugged in usb storage device with clamav?

    - by ossi
    I'd like to do an automatic virus scan on any plugged in usb device using ClamAV. I'm using Ubuntu 12.04. The closest thing I found was: Run clamav on mount of flashdrive How to run a shell script when a new USB storage device is detected? The first one is not working for me and the second one seems to target a known device. Is there a tutorial around I've missed? Or can I get some help with udev rules that apply to any usb storage device added? Currently nothing seems to do anything.

  • structure problem in Relational DBMS creation

    - by Kane
    For learning and understanding purpose, I currently want to try to make a small relational DBMS with simple features like (for now) only sequential reading/writing and CREATE TABLE, INSERT, SELECT, UPDATE and DELETE management. I am currently on the "think" part of the project and I am stuck on the way to store the read data in memory. First I was thinking of putting them properly on a structure, but the problem is that tables are all different, know the type of each column is not an issue, but I am not sure C provide a way to make fully dynamic structure. My second and current idea is to make a simple char array of the required length and just get the data by order with cast. But I am not sure if it is the good way to do that part, so I wanted to ask for your opinion and advices about that. Thanks in advance for your help. nb: I hope my question is enough clear and understandable, I still lack of pratice in english

  • Blender: How to "meshify" an object I made from Bezier curves

    - by capcom
    I made a star shape using Bezier curves, and extruded it (see pic below): What I want to do is give it a rounder look - not just around the edges by using beveling. I want it to kind of look like this (well, that shape anyway): How would I go about doing this? Please keep in mind that I am extremely new to Blender. I thought that I could somehow turn this star into those default shapes that have tonnes of squares which I could pull out, and apply a mirror to it so that the same thing happens on both sides. I really don't know how to do it, and would appreciate your help.

  • Cannot mount a CIFS network share on Ubuntu over VPN

    - by Aron Rotteveel
    I have setup u VPN connection to our Windows 2008 server at the office and it seems to work fine. For some reason, however, I still am not able to access the network shares over a VPN connection using my standard fstab entries. When I am physically connected to the network, it works fine, but now when trying this over VPN I get the following error: mount error(110): Connection timed out Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) My /etc/fstab looks like this: //server2008/share /mnt/share cifs iocharset=utf8,credentials=/home/aron/.smbcredentials,uid=1000 0 0 As said, it works fine when physically connected, but over VPN it just wont work. Any help is appreciated.

  • How to workaround or diagnose a kernel panic when "safely removing" external hdd?

    - by Shawn
    I'm experiencing an issue when using the "Safely Remove" option to remove my 1TB external HDD from the Unity Launcher. Not every time, but occasionally my screen will go black and display LARGE amounts of text information (which I obviously cannot screen cap). The jist of the info displayed is that unmounting or 'safely removing' the drive causes a kernel panic. Is there a Command Line command to remove mounted drives, or at least one that would show me some sort of error output when the drive is removed? I'm trying to narrow down the cause. I could be imagining this, but it seems to happen most often when I have other programs running when I remove the drive (i.e. Firefox, Transmission). Please note that my external drive is not in use when I attempt to remove it and it is not being used either by Firefox or Transmission at these times. Any help would be appreciated.

  • How to get windows back? Lubuntu?

    - by Jon
    I installed lubuntu and I don't like it. I did a clean install to lubuntu rather than making it dual. Now when I want to go back to Windows it won't work. I put the Windows Vista CD in and it won't load. It just loads lubuntu back. I know for a fact that the CD works just fine. I don't know what to do? I did a little research and it says I deleted the windows loader or the partition. Can someone help me?

  • 12.10 Booting Into Variations Of Blank Screen

    - by user93954
    I've been running the Ubuntu 12.10 beta since about a month before the final release with almost no problems. However since the day of release (I'm assuming an update has caused this) I have had problems booting into the actual GUI interface. Trying to get it to work is just a case of hard shutting down until it works, but for most of the time I need to battle with various different kinds of black screens. These include a plain black screen, a flashing line and a flashing line that doesn't fit the resolution. Nine times out of ten the cursor will be displayed over these. It also sometimes manages to boot into Ubuntu, albeit text mode or sometimes it loads GRUB which it isn't setup to do. If anyone could help out with this it'd be great. I really, really don't want to have to go through yet another clean installation. Cheers.

  • How do you organize information?

    - by zvrba
    I have a relatively large collection of useful books (paper and electronic), [academic] papers (mostly electronic) and web bookmarks. However, I don't have an overview of the material. Currently I have most of the electronic (PDF/DJVU) material in a single hierarchical folder and use filename search. Two questions. Do you have a similar problem, and how do you deal with it? Can you recommend some software to help with organizing bibliographic information, including web links. Easy editing of hierarchy and tags is a must. I would also like to be able to write own comments for each entry. [With my current scheme, just using the filesystem, does not provide other metadata.] A plugin for emacs would be perfect, but it's not a must. (org-mode MIGHT be adequate).

  • Why did Ubuntu and Windows start hanging mysteriously after I took a vacation?

    - by Ashrey Goel
    I installed Ubuntu alongside my Windows 7, after partitioning my HDD using Easeus partitioning manager. It was working perfectly, no problems, no data lost or corruption. Then I went away for 2 days and in my absence I don't know what happened in that period, now both Windows 7 and Ubuntu keep hanging continuously, like when you paint and change a brush it'll hang, I mean on very simple commands and I know my computer does not hang on such petty things. I use it for developing music and the specification are: Model: DELL-XPS Processor: Intel i5, 2.53 GHz RAM/Memory: 4GB Hard disk size: 500GB HDD Windows 7 partition: 417 GB Ubuntu Partition: 50 GB Please Help.

  • To what extent do code-signing certificates boost sales of your software?

    - by Dan W
    In the experiences of everyone here, have you found a certificate to boost sales of your (downloadable) program? I produce .NET software and upon clicking the installation file, Windows 7 pops up a message saying the software is from an "unknown publisher" and to proceed with caution. For Windows 8, this appears to be even more prominent, and may adversely affect the number of downloads, and therefore the number of sales. A certificate will help soften this 'warning' by (for example) changing the warning's colour from orange to blue, and give the publisher's name instead of 'unknown'. But I'd like more tangible evidence since many people are obviously used to that message, and may not care and download anyway. So has anyone noticed a jump in sales after the switch?

  • GParted wont resize extended partitions

    - by Magnum Frost
    I have dual booted windows 7 and Ubuntu 12.04 LTS and have decided that I need more space on my Ubuntu partition. I used gparted on a Live CD to shrink my Windows 7 partition (/dev/sda3) but when i try to resize the extended partition (/dev/sda4), which houses my linux partition (/dev/sda6), the right click options are greyed out and there is a key next to the extended partition. I have resized the partitions within the extended partition before to provide room, but now I can go no further with that, and need to grow the extended partition. The free space lies to the left of the extended partition and there is a small amount of free space directly to the right as well. Also, within the extended partition is /dev/sda5 (ntfs) , which I have no idea what is on it, but most of the space (3.42GB) is used, /dev/sda6 (ext4, mount point: /), my partition containing Linux, and /dev/sda7 (linux-swap). I hope you guys can help me with this because I really don't want to screw something up while trying to resize the extended partition.

  • Highlights from the Oracle Customer Experience Summit @ OpenWorld

    - by Richard Lefebvre
    The Oracle Customer Experience Summit was the first-ever event covering the full breadth of Oracle's CX portfolio -- Marketing, Sales, Commerce, and Service. The purpose of the Summit was to articulate the customer experience imperative and to showcase the suite of Oracle products that can help our customers create the best possible customer experience. This topic has always been a very important one, but now that there are so many alternative companies to do business with and because people have such public ways to voice their displeasure, it's necessary for vendors to have multiple listening posts in place to gauge consumer sentiment. They need to know what is going on in real time and be able to react quickly to turn negative situations into positive ones. Those can then be shared in a social manner to enhance the brand and turn the customer into a repeat customer. The Summit was focused on Oracle's portfolio of products and entirely dedicated to customers who are committed to building great customer experiences within their businesses. Rather than DBAs, the attendees were business people looking to collaborate with other like-minded experts and find out how Oracle can help in terms of technology, best practices, and expertise. The event was at the Westin St. Francis Hotel in San Francisco as part of Oracle OpenWorld. We had eight hundred people attend, which was great for the first year. Next year, there's no doubt in my mind, we can raise that number to 5,000. Alignment and Logic Oracle's Customer Experience portfolio is made up of a combination of acquired and organic products owned by many people who are new to Oracle. We include homegrown Fusion CRM, as well as RightNow, Inquira, OPA, Vitrue, ATG, Endeca, and many others. The attendees knew of the acquisitions, so naturally they wanted to see how the products all fit together and hear the logic behind the portfolio. To tell them about our alignment, we needed to be aligned. To accomplish that, a cross functional team at Oracle agreed on the messaging so that every single Oracle presenter could cover the big picture before going deep into a product or topic. Talking about the full suite of products in one session produced overflow value for other products. And even though this internal coordination was a huge effort, everyone saw the value for our customers and for our long-term cooperation and success. Keynotes, Workshops, and Tents of Innovation We scored by having Seth Godin as our keynote speaker ? always provocative and popular. The opening keynote was a session orchestrated by Mark Hurd, Anthony Lye, and me. Mark set the stage by giving real-world examples of bad customer experiences, Anthony clearly articulated the business imperative for addressing these experiences, and I brought it all to life by taking the audience around the Customer Lifecycle and showing demos and videos, with partners included at each of the stops around the lifecycle. Brian Curran, a VP for RightNow Product Strategy, presented a session that was in high demand called The Economics of Customer Experience. People loved hearing how to build a business case and justify the cost of building a better customer experience. John Kembel, another VP for RightNow Product Strategy, held a workshop that customers raved about. It was based on the journey mapping methodology he created, which is a way to talk to customers about where they want to make improvements to their customers' experiences. He divided the audience into groups led by facilitators. Each person had the opportunity to engage with experts and peers and construct some real takeaways. The conference hotel was across from Union Square so we used that space to set up Innovation Tents. During the day we served lunch in the tents and partners showed their different innovative ideas. It was very interesting to see all the technologies and advancements. It also gave people a place to mix and mingle and to think about the fringe of where we could all take these ideas. Product Portfolio Plus Thought Leadership Of course there is always room for improvement, but the feedback on the format of the conference was positive. Ninety percent of the sessions had either a partner or a customer teamed with an Oracle presenter. The presentations weren't dry, one-way information dumps, but more interactive. I just followed up with a CEO who attended the conference with his Head of Marketing. He told me that they are using John Kembel's journey mapping methodology across the organization to pull people together. This sort of thought leadership in these highly competitive areas gives Oracle permission to engage around the technology. We have to differentiate ourselves and it's harder to do on the product side because everyone looks the same on paper. But on thought leadership ? we can, and did, take some really big steps.

  • Is "code that generates code" really all that great?

    - by Jaxo
    I was looking through CodePen's "popular pens" and I noticed this cool little spiral animation somebody made with a seemingly ridiculously small amount of code. This is quite impressive until you click the headings for HTML and CSS to show the "compiled" versions of the same code. Suddenly the 3 lines of HAML and ~40 lines of SCSS turns into a gigantic monster of repetition. Here's where my question comes in: Is it acceptable to do something like this in practice? Don't get me wrong - I love using preprocessors to help me write code faster, but in some cases it looks like it's an automatic copy-paste machine.

  • Kiosk Mode Coding in Chromium

    - by Aaron
    I don't know how easy this would be, since I don't know anything about it, but I need an Ubuntu setup where the machine boots up, displays the login for a few seconds allowing a chance to log in as an admin, and then precedes to automatically log in to a user account which directly opens Chromium (any other browser is acceptable) in a kiosk mode where only the web content is visible, all Chromium keyboard shortcuts are disabled, and all but a select few websites are blocked, redirecting back to the home page after an "Unauthorized web page" warning comes up if the URL constraint is violated. Is it possible to code a kiosk setup like this, or am I asking for too much? If I'm simply uninformed, and there is already much documentation on anything like this, please redirect me to an appropriate page. If you can code or set up something like my description, please reply with step-by-step instructions, and instructions on how to modify the elements of the kiosk mode. Thank you in advance for any help. (Note: I'm currently using Ubuntu 10.04, but any distribution would work.)

  • [Silverlight] How to choose the webcam resolution

    - by Benjamin Roux
    Hello, Today I’m gonna show you how to choose the webcam resolution when using Silverlight. By default most of them are in 640x480 which can be sometimes insufficient. VideoCaptureDevice source = devices.SelectedItem as VideoCaptureDevice; source.DesiredFormat = new VideoFormat(PixelFormatType.Unknown, 4096, 4096, 30); The magic thing with this line, is that the camera will choose the best resolution available (and not absolutely 4096x4096). You can also get all the supported formats using the SupportedFormats property. Hope this help.

  • Cannot logon to POP server on my VPS or recieve emails

    - by Andy
    I recently purchased an unmanaged VPS to host my business websites, however I am struggling to get the email accounts working as I have only ever had experience with shared hosting. The VPS is running CentOS and I have Webmin/Virtualmin installed. I have added my domain, which is lyke.org.uk, and that is working OK. However, when I've added a user and tried to access their email account using Apple Mail, I've been able to establish a SMTP connection but I've not been able to login using POP. Furthermore, I've set up squirrelmail and I can send an email to any email address from there but I haven't recieved any that I have sent to that email address from other accounts. I would very much appreciate any help or suggestions as I am completely new to VPS and web hosting without Plesk or cPanel.
