  • Why can't I mount the Ubuntu 12.04 installer ISOs in Mac OS X?

    - by eric
    Over the past few days, I have downloaded both the 32 and 64 bit version of server and desktop to install on an Intel based PC. It is normal from within OS X to double click on an ISO and it will mount the ISO in the finder as well as within disk utility. When I attempt to mount any of the Ubuntu ISOs I downloaded, OS X returns the error message The following disk images couldn't be opened. The reason given for the error is no mountable filesystem. However, I am still able to open the ISO directly from disk utility and burn it to a DVD/CD. What has changed in this release to cause this? Is there something wrong with the current ISOs? The OS X machine I am using is only two weeks old and is having no issues with any other ISO.

  • Procedural Planets, Heightmaps and Textures

    - by henryprescott
    I am currently working on an OpenGL procedural planet generator. I hope to use it for a space RPG, that will not allow players to go down to the surface of a planet so I have ignored anything ROAM related. At the momement I am drawing a cube with VBOs and mapping onto a sphere. I am familiar with most fractal heightmap generating techniques and have already implemented my own version of midpoint displacement(not that useful in this case I know). My question is, what is the best way to procedurally generate the heightmap. I have looked at libnoise which allows me to make tilable heightmaps/textures, but as far as I can see I would need to generate a net like this. Leaving the tiling obvious. Could anyone advise me on the best route to take? Any input would be much appreciated. Thanks, Henry.

  • HTML5 Audio: Which formats? Ditch Ogg Vorbis in favor of Ogg Opus? Is MP3 still needed?

    - by phoibos
    I'm currently working on a website which has to stream audio files. Since bandwidth is always an issue, the file size should be as small as possible. I wonder what audio formats I should provide. MP3 - Most common format but low quality, I don't know if it's even required, since AAC is well supported by the browsers incapable of playing free codecs MP4 AAC - Nice quality / small filesize, supported by Safari / Mobile Devices / IE9 / Flash / Chrome A free codec - well, until recently, there only was Ogg Vorbis, but Ogg Opus is standardized now and it's really good! Questions: Is it time yet to use Opus instead if Vorbis? Firefox supports Opus since version 15, and Opera has support on its roadmap - I guess Chrome will follow in the future too. Do I still have to provide an MP3 file?

  • why my system gets frozen?

    - by user93019
    Is now something like 2 weeks since my system gets frozen while browsing the web, using apps, watching videos on web sites, basically using any part of my netbook, even when i'm only using one program (like the web browser) this happens. Is so frozen, that the only option i have left to do is to PRESS and hold the power button, nothing else works; I have seeing an error message telling me about a "compiz" error, but not all the times, and this happens every day, some times 2 or 3 times, during the same day. Why does this happens? how can i fix it? please help. Just to let you know i have my system up to date on 12.04 32 bits version, working on an Acer aspire AOD257, 1 Gb RAM, Intel® Atom™ CPU N570 @ 1.66GHz × 4 .

  • XBMC is slow and sluggish in Ubuntu 13.04; how can I speed it up?

    - by Dreamdealer
    I have a Zotac ZBOX ID84 with Intel D2550 proc and Nvidia GT520M GPU, 2GB memory and 320GB hard disk. I tried XBMCbuntu first and it ran perfectly for a few months until I started to mess around with the Terminal. After a re-install I could get the HDMI sound to work again so I installed the latest version of Ubuntu (13.04) instead. That worked fine. The sound and everything worked right away, but the interface of Ubuntu is sluggish and XBMC doesn't run as good as it did in XBMCbuntu. The video playback is slow and it stutters. It speeds up and slows down with the complexity of the video. So, the PC is more than capable to run XBMC and play the videos, but something in Ubuntu (GUI?) slows it down to an unusable pace. Can anybody tell me what I can do to speed things up? Since I'm new to Ubuntu I have no clue where to start looking.

  • Advice on triple/quadruple-booting?

    - by professorfish
    I am currently running Windows 7 Home Premium x64 on my laptop. I would like to install more than one Linux distro, IN ADDITION TO Windows 7. How do I go about this, what do I need to be careful and aware of, is it possible? The specific distros I might eventually install: Definitely: Ubuntu (is it a good idea to install the Linux-Secure-Remix version?) Almost definitely: OpenSUSE Probably: Zorin Possibly: Arch Possibly: Fedora Possibly: FreeBSD Computer details: Successfully used WUBI for Ubuntu in the past Recently reinstalled Windows using the RECOVERY partition Windows 7 Home Premium x64 model: ASUS K53U series AMD Brazos Dual Core E450 1.65 GHz 750GB hard drive, currently partitioned into C: (300GB total, 246 GB free), D: (373GB - total, 167 GB free), and RECOVERY (the rest of the space, I think) 4GB RAM Can I be sure that GRUB will work, if WUBI has worked? In short, how do I go about triple- or quadruple-booting Windows 7, Ubuntu and other distros? What do I need to be aware of? How do I set up the partition structure? Thank you in advance

  • A bacon- (and module-) saving PowerShell incident

    - by AaronBertrand
    Earlier today I made a big goof. I opened a module in Notepad, intending to use it as the basis for a new module. I was in the process of using "File > Save As" when my phone rang just at the precise instant that, for some reason, made me click on "File > Save" by mistake. After hitting Ctrl+Z 30 times to try to get the old version of the module back, I remembered that Notepad has never had more than one level of Undo. Back when I was coding ASP by hand, I was very well aware of this, but I...(read more)

  • 12.04 cannot boot from USB

    - by GhostRider
    The HP Pavilion g6 notebook is unable to boot from bootable USB stick created with Linux Live USB Creator. I was able to boot other systems using the same pendrive. I have changed the boot priority using F10. When I restarted, it didn't ask for any message like Press any key to boot from When I press F19, and selected the pendrive from the available options to boot from, while restarting it gives me a message: error while trying to boot selected boot image Though I looked into the possible suggestions here, none of them worked. Looking for any help? EDIT: I was able to fix the first issue, i'e ubuntu could be installed as secure boot option in the bios was not allowing the pendrive or cd/dvd to be detected. Now once i have successfully installed ubuntu 12.04, after the restart i was unable to find it in the os menu for selection and windows8 loaded by default Ubuntu version: 12.04

  • Ubuntu 12.04 freezing on startup

    - by Frank
    Have been looking everywhere to find a solution to this problem but have yet to find a solution. I am running 64 bit 12.04 LTS on a AMD C-50 Dual core 6 gigs ram AMD Ratheon HD 6250. The problem I am experiencing is when ubuntu gets to the wallpaper screen it will sometimes freeze soon after the the image appears or shortly there after gnome loads locking up keyboard and mouse. When I try to log in via the console the same thing happens (this is as ubuntu is loading). At the moment the system is set to auto login previously it was set to ask for password but it did the same thing. Switching to from lightdm to gdm did nothing to alleviate the issue. I have never had so many issues with ubuntu I have to say 12.04 is the most buggy version yet.

  • How to introduce a computer illiterate 50-year old to programming [closed]

    - by sunday
    The other day my dad asked me a question that I would have never expected from him. "How can I learn C++?" My dad is turning 56 this year and computers are a distant concept for him. He doesn't know how to use a phone very well besides calling numbers (no speed dial or contacts); though he has started to learn computers a little better - to the point that he knows how to open the internet (in Windows) and browse around (and has successfully completed several job applications entirely on his own online, of which he was offered positions too). But still, these are too narrow-windowed experiences to mean much, really. While he may not have the background, my dad knows how to read. And I mean reading as a skill, not just an ability. He has little to no college education (financial problems, family, etc.) and was fortunate enough to finish high school, but still taught himself to become a master electrician and has been one for almost 30 years now. He did the same with guitar, learning to play at a very professional level and has been praised for his skill. In high school, he picked up a weight lifting book - and was the only person in his high school at the time to qualify officially as an "athlete" by national standards. In all cases, he just needed something to read. Something to teach him. He absorbs information like a sponge. I have no doubt in my dad's motivation or capability of doing this, so my general goal is simply: Get my dad into the world of computers, and get him on the road to programming. I strongly believe that once I get him through the fundamentals, his drive and reading skill will keep him going on this own. So I'm asking you all: where should I start with all this? And what are the best resources out there? Should I get him to start Linux instead of Windows? Is C++ a bad idea? Remember, he needs to (IMO) learn computers first, and then get that first grasp (the "Hello world" experience) of programming. For money's sake and at top preference, I'd like free online resources that he can read, but by all means any good suggestions in print or paid-for-online are welcome (that I could possibly look into later to purchase). And also, I intend to start him off with C++ (no Python, Java, etc.), because I know it the best and will be able to help him along the way with code. (I have minimal knowledge right now in other languages). Edit: I'm getting a lot of persistent suggestions to use Python. The only reason I wanted to do C++ is that I KNOW it and can be THERE when my dad needs help. My VERY FIRST exposure to programming ever was Java. I learned Java, and I got good at it. I open to other suggestions, but please provide an effective application of your suggestions. EDIT #2: I understand my approach/thinking/knowledge could be lacking here. I'm a sophomore level undergraduate CS major. If you don't agree with anything in my post, tell me why - give me ideas, information - that's why I'm asking in the first place. To narrow down my general goal to specific reachable goals.

  • My Favourite Two Buttons in Denali CTP1 SSIS

    In SSIS for SQL Server 2005 and SQL Server 2008 when you delete something from the design surface it is gone.  The only real way of getting the deleted item(s) back is to revert to a previous version of the package or to redo the deleted items manually.  Neither of these options is particularly great.  I have made this mistake before and cursed not having CTL+Z and CTL+Y.  Denali changes this.  We can now undo and redo.  Very very welcome.  Well done, finally, the SSIS team.

  • Launch Specific OEPE Workspace from the Start Menu

    - by user647124
    I frequently have multiple Eclipse-based projects running simultaneously, sometimes on different versions of Eclipse. I have made a mess of a few workspaces by accidentally opening them in the wrong version of Eclipse. To thwart my own forgetfulness, I went seeking a way to launch directly to a workspace and found it at http://stackoverflow.com/questions/209789/starting-eclipse-w-specific-workspace. Essentially, add the -data switch to your icon's open command, such as: C:\eclipse\eclipse.exe -data E:\MyData\Clients\Confidential\EclipseGCDPGive it a unique name and stick it on your Start Menu (C:\ProgramData\Microsoft\Windows\Start Menu). Makes my life a bit easier and hopefully yours, too.

  • How to install ubuntu 12.04

    - by William A. Jordan
    I've had ubuntu on my pc for about 5 years,after the new 12.04 version and a day and a half trying to get it to just boot up. I will take it off my pc and rely on windows. I have 5 pc's which I built and am not an amateur, After installing it numerous times and even to run it from your webpage (to no avail). Granted I do have nvidia drivers on it, but after I went to their webpage and downloaded and installed the linux driver it,it still would not boot, by the way I took 2 different pc's apart and used what I thought were compatible (I shouldn't have to do this) parts. I have it on a seperate hd which I will remove and format. Have a nice day and so long (2 much trouble).

  • Hardware refresh of Solaris 10 systems? Try this!

    - by mgerdts
    I've been seeing quite an uptick in the people that are wanting to install Solaris 11 when they are doing hardware refreshes.  I applaud that effort - Solaris 11 (and 11.1) have great improvements that advance the state of the art and make the best use of the latest hardware. Sometimes, however, you really don't want to disturb the OS or upgrade to the a later version of an application that is certified with Solaris 11.  That's a great use of Solaris 10 Zones.  If you are already using Solaris Cluster, or would like to have more protection as you put more eggs in an ever growing basket, check out solaris10 Brand Zone Clusters.

  • Windows 8 on my new i7 Macbook Pro

    - by Bob Hardister
    Using bootcamp I installed Windows 8 on my new Macbook Pro 15" (not a retina screen version), which has OS X 10.8.2, 2.6 Ghz Core i7 with 8 GB RAM.  I followed the simple procedure outlined here. The only problem I had was the wireless device driver wasn't provided. I had to find and download it myself. Even so it only provided 5G not 2G protocol support. I downloaded a Broadcom driver.   I was able to enable the Hyper-V features on Windows 8 and look forward to using VMs. So far so good :)

  • Dell b1160w not working in 14.04

    - by mission007
    I originally installed the dell b1160w printer on ubuntu 12.04. It worked as expected. A few months ago I upgraded to ubuntu 14.04 and now I can't get the printer to work. I looked at the driver information on the dell site. They have not updated their driver since 2013 so 12.04 is the latest version with a supported driver. Is there a work around for this problem, like a generic driver that I can use or a way to install whatever printer interface ubuntu 12.04 was using? I have a windows virtual box. I can get it to work through there, but it's inconvenient to pull up my virtual box and transfer the files over to it anytime I want to print.

  • How to install Ubuntu using a USB stick?

    - by J. N.
    I cannot install Ubuntu 11.10 from a USB stick. It doesn't boot to Ubuntu page for installation but remains on Windows 7. I've downloaded the 11.10 version iso file and burnt it to a USB stick. After I inserted it, the USB stick is a symbol of Ubuntu installation and I clicked wubi to try to install it. But it didn't boot to Ubuntu but stayed on Win 7 after restart. It occurred error and said "windowsBackend" object has no attribut "cd_path" when I chose "Help me to boot from CD". I thought it's the problem of my computer model (acer travelmate 8481), but it can't boot on an old computer using XP as well. How can I solve this problem and install Ubuntu to replace Windows?

  • Ubuntu 13.10 vs 12.04 LTS

    - by Shaun
    I am migrating my workflow to ubuntu from windows. I have a macbook pro at home and I really enjoy being able to use the workspaces feature on ubuntu to increase my productivity. As myself being someone that isn't very familiar with doing command line things and hasn't worked with linux a whole lot other than doing basic commands like cd, ls, rm, screen, and sudo. I was wondering what you think would be the best choice for a ubuntu version. I am looking for ease of use as well as stability. I spend most of my time working with eclipse, as well as writing documents. On a side note, right now I have a pretty high end workstation, but I am using a crappy notebook 2.5 inch 1TB hard drive for my system. Would it be worth it to switch to a top of the line SSD, or would the difference not really be noticeable? How difficult would it be for a newcommer to setup the system with the os and important folders running on a SSD and then other folders for storage running on a HD.

  • Ubuntu 14.04 compiz thumbnails preview flicker

    Ubuntu 14.04.1 x64 (upgraded from 12.04) with Unity desktop Dell Latitude with NVIDIA GF119M (NVS 4200M) - Optimus is DISABLED Using NVIDIA legacy binary driver 304.117 When I set the CCSM option to allow thumbnail previews, the thumbnail 'flickers' for about 1 second before the actual thumbnail image is displayed. I don't think I had this enabled under 12.04 so not sure if it's version-specific. Should I be using a different driver (there are newer ones - Ubu shows NVIDIA binary driver 331.38 and the non-proprietary nouveau, plus NVIDIA has newer ones at the site)? TIA!
