  • HTML5 video capture and streaming?

    - by Shyatic
    I'm working on kind of an educational site, where there are teachers and students around the world (potentially). Since it's a non-profit site, and I don't have the need for it to be done tomorrow (kind of a side project of something bigger), I wanted to know the best way to figure out how to do this. I'm not a programmer by trade, I've been on the systems side of things for years, but I understand most technology and the question here is more how to gauge what to do so I can get the right resources in place. That said... here's what I am looking at. I figure the future is HTML5, and that's probably where I'd rather spend my efforts given that it will be cross platform and without the need for plugins. It will work on mobile as well. Question is, how well does HTML5 handle input media, say desktop capture and camera, or on mobile perhaps, where I'd want to use the user's phone camera, etc. Second question is dynamic streaming... I've read about MPEG DASH, then there are technologies like Smooth Streaming (which I think given the way Silverlight is going is going to be gone or useless), then also Apple and Flash, but if I'm doing HTML5 it doesn't benefit me. Any ideas here would be really helpful, and the more detail the better! :) That's about it... there are free chat services out there like using the MSN Web Chat controls (how good they are, I don't know, but worldwide most people have a Hotmail/MSN account) so I can use that for chat. I don't know its limitations of course, but that's something if people know or have suggestions, then I'm all ears. Thanks for the help, I greatly appreciate it!

  • Resolution stuck in 640x480 in grub, 11.04 and 12.04

    - by user89797
    I have three operating systems on my machine, Windows 7x64, Ubuntu 11.10 and 12.04 both x64 as well. All three were running at full resolution for my monitor, as well as in the Grub 1.99 boot screen. After booting into Windows, I rebooted my machine and found my Grub resolution was suddenly 640x480. Booting into both versions of Ubuntu, I find myself stuck at that resolution as well. I made no driver changes recently, and hadn't even booted into the 11.10 build in a month or more. I've gone through both proprietary Nvidia driver options for my card (GeForce 9800GT) as well as the open source drivers in 12.04 to no avail. I can't figure out what could have caused this change in both versions of Ubuntu and Grub simultaneously. Windows 7 is unaffected so I think that safely rules out hardware failure. EDIT Ok, so I couldn't boot an graphical live disks, I tried ubuntu 12.04 i386 and x64 as well as 12.10 beta x64 and all of them would flash the initial logo, go to a blank screen with a flashing cursor in the upper left and then my display would die. I managed to boot 12.04 server and get into recovery. I reinstalled grub and went into recovery mode for my 12.04 build. If I boot in safe graphics mode I can get 1280x768, but as soon as I reboot it's broken again. I've tried reinstalling the nvidia drivers and that leaves me with a system stuck at max 640x480. None of these changes have had any impact on the 11.10 build, which is still stuck at 640x480 Given that I can push a somewhat higher resolution in 12.04, and full resolution in windows 7 I'm pretty convinced it's not an issue of my monitor failing. It must be something to do with the graphics drivers. I can't figure out what could be the issue though. I'm especially perplexed that I can't boot any live images

  • Can I use a 302 redirect to serve up static content from a url with escaped_fragment?

    - by Starfs
    We would like to serve up seo-friendly ajax-driven content. We are following this documentation. Has anyone ever tried to write a 302 redirect into the htaccess file, that takes the '?_escaped_fragment=' string and send that to a static page? For example /snapshot/yourfilename/ How will Google react to this? I've gone through the documentation and it's not very clear. The below quote is from Google's documentation this is what I find. I'm not sure if they are saying that you can redirect the _escaped_fragment_ url to a different static page, or if this is to redirect the hashtag URL to static content? Thoughts? From Google's site: Question: Can I use redirects to point the crawler at my static content? Redirects are okay to use, as long as they eventually get you to a page that's equivalent to what the user would see on the #! version of the page. This may be more convenient for some webmasters than serving up the content directly. If you choose this approach, please keep the following in mind: Compared to serving the content directly, using redirects will result in extra traffic because the crawler has to follow redirects to get the content. This will result in a somewhat higher number of fetches/second in crawl activity. Note that if you use a permanent (301) redirect, the url shown in our search results will typically be the target of the redirect, whereas if a temporary (302) redirect is used, we'll typically show the #! url in search results. Depending on how your site is set up, showing #! may produce a better user experience, because the user will be taken straight into the AJAX experience from the Google search results page. Clicking on a static page will take them to the static content, and they may experience avoidable extra page load time if the site later wants to switch them to the AJAX experience.

  • Correct nvidia+intel graphics setup in 14.04

  • alt+tab moves windows between workspaces and crashes unity

    - by Ruslanchik
    I have recently been using multiple workspaces in unity but have run into a bug that is making it very difficult to do this effectively. The problem is with alt+tab. When I am focused on a window that is not in the primary (top-left) workspace one of two things happens: Unity restarts (the launcher and menu bar disappear and screen flashes blank before everything reappears) and all of my windows are moved to different workspaces. The focused window is always moved to the primary workspace and other windows are typically moved one workspace to the left. alt+tab will usually function normally after this. Unity completely crashes. The windows in the current workspace are still there, but the launcher and menu bar are gone, I cannot switch between workspaces, and none of the hotkeys work. The same issues occur when using alt+` as well. I have installed ccsm, but have made only minor adjustments with it. I am still using the Unity switcher. I actually uninstalled ccsm hoping that would resolve the issue, but the issue persists. Is there some resolution to this issue? I like Unity and want to keep using it, but having to use the mouse to switch between programs is irritating and enough reason to switch to Gnome.

  • Cannot get temperatures in Dell Studio 1558

    - by Athul Iddya
    I could never get proper temperatures on my Dell Studio 1558. lm-sensors and acpi give wrong readings. The output of sensors is, $ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +26.8°C (crit = +100.0°C) temp2: +0.0°C (crit = +100.0°C) acpi -V gives me, $ acpi -V Battery 0: Full, 100% Battery 0: design capacity 414 mAh, last full capacity 369 mAh = 89% Adapter 0: on-line Thermal 0: ok, 0.0 degrees C Thermal 0: trip point 0 switches to mode critical at temperature 100.0 degrees C Thermal 0: trip point 1 switches to mode passive at temperature 95.0 degrees C Thermal 0: trip point 2 switches to mode active at temperature 71.0 degrees C Thermal 0: trip point 3 switches to mode active at temperature 55.0 degrees C Thermal 1: ok, 26.8 degrees C Thermal 1: trip point 0 switches to mode critical at temperature 100.0 degrees C Thermal 1: trip point 1 switches to mode active at temperature 71.0 degrees C Thermal 1: trip point 2 switches to mode active at temperature 55.0 degrees C Cooling 0: LCD 0 of 15 Cooling 1: Processor 0 of 10 Cooling 2: Processor 0 of 10 Cooling 3: Processor 0 of 10 Cooling 4: Processor 0 of 10 Cooling 5: Fan 0 of 1 Cooling 6: Fan 0 of 1 I suspect even hddtemp gives bogus readings as its always at 46 $ sudo hddtemp /dev/sda /dev/sda: ST9500420AS: 46°C I have gone through some bug reports and some used to have the same problem after resuming from suspend. But I always have this problem. I had updated to the latest BIOS from Windows a couple of weeks ago, will updating from Ubuntu change anything? CORRECTION: hddtemp's readings do change. Its now at 45.

  • Unable To Get Sound Working to External Speaker on HP TouchSmart 320 on 11.04 or 11.10

    - by Schof
    This is an HP TouchSmart 320, model number 320-1200m. I'm using Ubuntu 11.04. Hardware information: root@hp320:/home/mpower# aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Generic [HD-Audio Generic], device 0: STAC92xx Analog [STAC92xx Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 root@hp320:~$ cat /proc/asound/card0/codec#0 | grep Codec Codec: IDT 92HD91BXX Sound to headphone jack works properly, but sound to built-in speakers does not work. I have installed Windows, and with Windows 7 installed, all audio hardware works properly, so this isn't a hardware fault. I've looked at https://help.ubuntu.com/community/HdaIntelSoundHowto and have been unable to find my card in http://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio-Models.txt . I have tried adding almost every conceivable model in the line "options snd-hda-intel model=MODEL" line I added to /etc/modprobe.d/alsa-base.conf. Update 2011-11-09 2:31 PM PST: I've gone to Control Center - Sound Preferences to attempt settings that make sound work. The "Hardware" tab shows one device: "Internal Audio 1 Output / 1 Input Analog Stereo Duplex." There are two output profiles listed in the selection box at the bottom of the tag: Analog Stereo Duplex and Analog Stereo Output. Neither cause sound to emit from the speakers. I've also run alsamixer on the command-line and ensured that everything is set to maximum and nothing is muted. Update 2011-11-09 5:15 PM PST: I've replicated the exact same symptoms in 11.10. Update 2011-11-10 11:31 AM PST: I've filed a bug in launchpad: https://launchpad.net/ubuntu/+source/alsa-driver/+bug/888703

  • Directory error when trying to create a new user

    - by Tom Brossman
    I added a second user 'shirley' in Settings - User Accounts, and set a password. The account type is Standard. In 11.04, this worked and I logged in and had a functioning desktop for this user. How is this done in 11.10? When I try to log in as this user I have this error: Nautilus could not create the required folder "/home/shirley/.config/nautilus". Before running Nautilus, please create the following folder, or set permissions such that Nautilus can create it. The only option then is to click OK, this dumps me out to full-screen Nautilus, like this: There is no launcher or visible way to start any programs. Print screen doesn't take a screengrab. The desktop is similar to this question but I get no terminal when I press CTRL+ALT+T. I have to press CTRL+ALT+F2 and restart from the terminal to get out of this. This answer is to install gnome-system-tools. Shouldn't I be able to add a second user with the default install? EDIT: I tried the deluser+adduser suggestion, there was no change after trying it. Here is what I got: tom@desktop:~$ sudo deluser shirley [sudo] password for tom: Removing user `shirley' ... Warning: group `shirley' has no more members. Done tom@desktop:~$ sudo adduser shirley Adding user `shirley' ... Adding new group `shirley' (1001) Adding new user shirley' (1001) with groupshirley' The home directory '/home/shirley' already exists. Not copying from `/etc/skel'. Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully Changing user information for shirley Enter the new value, or press ENTER for the default Full Name []: Room Number []: Work Phone []: Home Phone []: Other []: Is the information correct? [Y/n] y What has gone so wrong with simply adding a second user? Am I the only one having this problem? I'd reinstall if that fixed things, but this is a fresh install only a few days old.

  • An experiment: unlimited free trial

    - by Alex.Davies
    The .NET Demon team have just implemented an experiment that is quite a break from Red Gate's normal business model. Instead of the tool expiring after the trial period, it now continues to work, but with a new message that appears after the tool has saved you a certain amount of time. The rationale is that a user that stops using .NET Demon because the trial expired isn't doing anyone any good. We'd much rather people continue using it forever, as long as everyone that finds it useful and can afford it still pays for it. Hopefully the message appearing is annoying enough to achieve that, but not for people to uninstall it. It's true that many companies have tried it before with mixed results, but we have a secret weapon. The perfect nag message? The neat thing for .NET Demon is that we can easily measure exactly how much time .NET Demon has saved you, in terms of unnecessary project builds that Visual Studio would have done. When you press F5, the message shows you the time saved, and then makes you wait a shorter time before starting your application. Confronted with the truth about how amazing .NET Demon is, who can do anything but buy it? The real secret though, is that while you wait, .NET Demon gives you entertainment, in the form of a picture of a cute kitten. I've only had time to embed one kitten so far, but the eventual aim is for a random different kitten to appear each time. The psychological health benefits of a dose of kittens in the daily life of the developer are obvious. My only concern is that people will complain after paying for .NET Demon that the kittens are gone.

  • Issues with Cinnamon?

    - by Corrodie
    I just recently switched my system over to Ubuntu 12.10, and decided on Cinnamon as my environment-- it all worked fine, at first. But I was poorly educated and started using Compiz and Emerald along with it--Setting both as replacements in startup processes. I now know, that's a big, big mistake. Now when loading Cinnamon, I am greeted to my background image, and only that. My only options seem to be to open a terminal. I was advised to attempt muffin --replace and mutter --replace Neither to any avail, the terminal closes, and I cannot load another one unless I completely reload. I went back to Unity, purged and autoremoved Cinnamon, emerald, and compizconfig, and attempted to reinstall Cinnamon, thinking that would solve the problem--no, it came back just as broken as before. So, I reinstalled ubuntu, then cinnamon---still broken. I'm assuming I must find a way to remove the replace commands-- but as I have no menu, I'm not positive I can do that. Is there any way I can access the startup processes via terminal? I'd think though, if I completely removed Cinnamon, all configurations would be gone too, so, it's just not making much sense. Is there some kind of reset I could possibly do? I've been browsing forums and questions here, all leading to things I'd already done, so, it can't hurt to ask for myself. I apologize if you would rather I have posted this over at mint. Next time, I will definitely check compatibility instead of assuming something just has to work. Any help is greatly appreciated, thanks! ****EDIT***** It seems although it didn't allow me to do it before, I was now allowed to access the settings and startup processes for Cinnamon via Unity, and, after quickly removing aforementioned processes- I'm up and running again.

  • Demantra Implementation Tip Windows and Unix or Linux

    - by user702295
    Hello!  Are you implementing using a third party or consulting resources?   Recently we have seen some cases where customers no longer have a windows installation.  After the initial install and configuration, once the instance has gone live, the windows install is either deleted or most likely no longer with the customer as the same was installed on the implementers' laptop to start with. As a result when support comes back requesting the customer to apply a patch and/or upgrade they do not have a windows installation.  This has started happening after Oracle Demantra gave them the option to configure the engine on Unix.  Workaround: It is advisable that the customer keep their Windows installation intact for further patching and/or upgrade.  It is aslo possible that the implementer had installed Demantra on his Windows box and you do not have access to it any more.  It is possible that with the web and engine on Unix, and the silent installer having downloaded all the executable for Business Modeler, to work on the User's client machine, you may no longer need the windows install. I have not tested the above

  • Algorithm to measure how "diffused" 5,000 pennies are in an economy?

    - by makerofthings7
    Please allow me to use this example/metaphor to describe an algorithm I need. Objects There are 5 thousand pennies. There are 50 cups. There is a tracking history (Passport "stamp" etc) that is associated with each penny as it moves between cups. Definition I'll define a "highly diffused" penny as one that passes through many cups. A "poorly diffused" penny is one that either passes back and forth between 2 cups Question How can I objectively measure the diffusion of a penny as: The number of moves the penny has gone through The number of cups the penny has been in A unit of time (day, week, month) Why am I doing this? I want to detect if a cup is hoarding pennies. Resistance from bad actors Since hoarding is bad, the "bad cup" may simply solicit a partner and simply move pennies between each other. This will reduce the amount of time a coin isn't in transit, and would skew hoarding detection. A solution might be to detect if a cup (or set of cups) are common "partners" with each other, though I'm not sure how to think though this problem. Broad applicability Any assistance would be helpful, since I would think that this algorithm is common to Economics The study of migration patterns of animals, citizens of a country Other natural occurring phenomena ... and probably exists as a term or concept I'm unfamiliar with.

  • My site has crashed .. anyone have some info ?

    - by marwan
    Hi all , I booked a domain name for my website from a hosting provider .I gave the domain name , along with ftp details to a freelancer to develop the site in wordpress . the freelancer developped and he got full payment , and the site and site was working fine ,etc .. From that time , I did not change the admin logging as well as ftp details , this means that such info is still known to the freelancer .. A week ago , I found that some links in my site was not working .. I sent him a mail about this , and he said that he will fix it if i give him ftp details . and I did so , next I found that the entire site is gone . then he sent me a mail , without I asked him , and he he said that there have been someone who got access to my server , and he removed all files of my site and he installed drupal instead .and that he can rebuild the site in one day , by charging a full fee of 250 usd again .. Can anyone know what I can do in this situation , to find who did such act , could it be the host provider or that freelancer ,, and if there is a possibility to have my site back top the server .. I will appreciate any info on this.. Regards , Thanks

  • Why don't windows of the same application behave as they should?

    - by Yuttadhammo
    Somewhere along the upgrade path, Unity has developed some strange logic behind window layering. First, before Oneiric, there was a way to see all the windows of an application - I think it was when you click on the icon in the launcher. Now, clicking on the icon often does nothing. Suppose I have two terminals open, one behind this Firefox window, and one in front of it. Clicking on the launcher does nothing - the only way to find the second terminal, afaics, is to move the Firefox window or use the task switcher. Secondly, once I have both terminals on top, then I decide to close one of them, suddenly they both disappear (the second one, for some reason, has gone into hiding behind the Firefox window). Third (though I can't pin it down now), sometimes when a window is on top, focus is still on a window in back; I click on the top x to close the window in front, only to find I've closed an important window in the back. (Update: this question details the problem) I can't really believe these are bugs, since they seem too obvious to not have been fixed by now. My question is, am I missing something? Some compiz option I can set to make it act like it used to? Or is this really how Unity is supposed to act?

  • Understanding and memorizing git rebase parameters

    - by Robert Dailey
    So far the most confusing portion of git is rebasing onto another branch. Specifically, it's the command line arguments that are confusing. Each time I want to rebase a small piece of one branch onto the tip of another, I have to review the git rebase documentation and it takes me about 5-10 minutes to understand what each of the 3 main arguments should be. git rebase <upstream> <branch> --onto <newbase> What is a good rule of thumb to help me memorize what each of these 3 parameters should be set to, given any kind of rebase onto another branch? Bear in mind I have gone over the git-rebase documentation again, and again, and again, and again (and again), but it's always difficult to understand (like a boring scientific white-paper or something). So at this point I feel I need to involve other people to help me grasp it. My goal is that I should never have to review the documentation for these basic parameters. I haven't been able to memorize them so far, and I've done a ton of rebases already. So it's a bit unusual that I've been able to memorize every other command and its parameters so far, but not rebase with --onto.

  • OnTrigger not firing consistently

    - by Lautaro
    I have a Prefab called Player which has a Body and a Sword. The game uses 2 instances of Player, Player1 and Player2. I use Player1 to strike Player2. This is code on the sword. My hope is that Sword of Player1 will log on contct with Body of Player2. It happens but only the first hit and then i have to hit several times before another strike is logged. But when i look at log from OnTriggerStay it looks like the TriggerExit is never detected untill long after the sword is gone. void OnTriggerEnter(Collider other) { //Play sound to confirm collision var sm = ObjectDirectory.soundManager; sm.PlaySoundClip(sm.gui_02); Debug.Log(other.name + " - ENTER" ); } void OnTriggerStay(Collider other) { Debug.Log(other.name + " - collision" ); } void OnTriggerExit(Collider other) { Debug.Log(other.name + " - HAS LEFT" ); } DEBUG LOG: Player2 - ENTER UnityEngine.Debug:Log(Object) SwordControl:OnTriggerEnter(Collider) (at Assets/Scripts/SwordControl.cs:28) Player2 - collision UnityEngine.Debug:Log(Object) SwordControl:OnTriggerStay(Collider) (at Assets/Scripts/SwordControl.cs:34) (The last debug log then repeated hundreds of times long after the sword of player 1 had withdrawn and was in no contact with player 2 ) EDIT: Further tests shows that if i move player1 backwards away form player2 i trigger the OnTriggerExit. Even if the sword is not touching Player2 since after the blow. However even after OnTriggerExit it takes many tries untill i can get another blow registered.

  • How do I source a shell script for Node Version Manager?

    - by Matthew Patrick Cashatt
    Hi and thanks for looking! I am new to Linux/Ubuntu, but I have set up an Ubuntu box on which to run Node.js. I have had moderate success, but now I need to be able to easily upgrade my version of Node. Many folks recommend using Node Version Manager. I followed the directions, but when I try to do something like this: nvm ls I get a messaging stating that No command NVM found I have gone back to check the steps I followed to install NVM, but there is one part that is tricky for may and I think to be the culprit: sourcing the file for bash. From the instructions: To activate nvm, you need to source it from your bash shell . ~/nvm/nvm.sh I always add this line to my ~/.bashrc or ~/.profile file to have it automatically sources upon login. Often I also put in a line to use a specific version of node. So which file should I add this to? I am guessing profile since it's ubuntu?? Also, where in the file do I add this line? After I have added this line, do I need to reboot or anything? Any help would be deeply appreciated--especially if you can show me an example profile file with . ~/nvm/nvm.sh integrated so that I can see usage. Thanks, Matt

  • Working with Reporting Services Filters–Part 5: OR Logic

    - by smisner
    When you combine multiple filters, Reporting Services uses AND logic. Once upon a time, there was actually a drop-down list for selecting AND or OR between filters which was very confusing to people because often it was grayed out. Now that selection is gone, but no matter. It wouldn’t help us solve the problem that I want to describe today. As with many problems, Reporting Services gives us more than one way to apply OR logic in a filter. If I want a filter to include this value OR that value for the same field, one approach is to set up the filter is to use the IN operator as I explained in Part 1 of this series. But what if I want to base the filter on two different fields? I  need a different solution. Using the AdventureWorksDW2008R2 database, I have a report that lists product sales: Let’s say that I want to filter this report to show only products that are Bikes (a category) OR products for which sales were greater than $1,000 in a year. If I set up the filter like this: Expression Data Type Operator Value [Category] Text = Bikes [SalesAmount]   > 1000 Then AND logic is used which means that both conditions must be true. That’s not the result I want. Instead, I need to set up the filter like this: Expression Data Type Operator Value =Fields!EnglishProductCategoryName.Value = "Bikes" OR Fields!SalesAmount.Value > 1000 Boolean = =True The OR logic needs to be part of the expression so that it can return a Boolean value that we test against the Value. Notice that I have used =True rather than True for the value. The filtered report appears below. Any non-bike product appears only if the total sales exceed $1,000, whereas Bikes appear regardless of sales. (You can’t see it in this screenshot, but Mountain-400-W Silver, 38 has sales of $923 in 2007 but gets included because it is in the Bikes category.)

  • How do I keep controversy in check?

    - by Aaron Digulla
    This is probably OT but it's less OT here than on any other SO site, so please bear with me. I'm working on a new project votEm. The goal is to give independent candidates a platform to introduce themselves to get elected for a political office. My main reason is that today, it's too expensive to run for an office. Some politicians in the US spend as much as 30 million dollars (!) for a single campaign. That money is better spent elsewhere. In a similar fashion, people who want to change countries like Egypt, could use such a platform to present themselves. Now I expect a lot of emotions and pressure on my site. People with a lot of money (and a lot to lose) will try to game it (political parties, secret services of ... errr ... "not 100% democratic countries", big companies, ...) To avoid as many mistakes as possible, I need a list of resources, ideas and tips how to keep such a site out of too much trouble. PS: I'd make this CW but the option seems to be gone...

  • Free space in tmpfs partition not adding up

    - by Dean Herbert
    I have had my /tmp/ partition filling up recently when it should not be anywhere near full. On further investigation, I found that the partition was listing free space a lot lower than it should be. I am guessing a remount will fix this, but am very curious as to why this has happened and where this space has gone. du output: root@odoroki:/tmp# du --summarize -h 3.3M . df output: root@odoroki:/tmp# df -h /tmp Filesystem Size Used Avail Use% Mounted on tmpfs 3.9G 3.3G 653M 84% /tmp Update: after deleting some files it has happened again. du output: root@odoroki:/tmp# du -h --summarize 11M . df output: root@odoroki:/tmp# df -h /tmp Filesystem Size Used Avail Use% Mounted on tmpfs 3.9G 3.9G 0 100% /tmp I have a feeling this has started since a recent apt-get upgrade, but it still seems like strange behaviour. I did do a quick scan over lsof output and couldn't see any open/stuck file handles. Unfortunately due to the seriousness of the issue I had to reboot the server, after which usage seems to match correctly.

  • How to add a new developer to the team

    - by lortabac
    I run a small company composed of only 2 developers. For one of our clients we are building a very big application, whose development has gone on for 1.5 years. Now this client has found an important sponsorship, and they are organizing some events related to this project, so we have a deadline in 2 months and we can't miss it. We are thinking of adding a new developer to the team, and I am wondering what we can do to help his integration. This is the situation: We are approaching the threshhold of Brooks's law, the point when adding new developers will be counter-productive. The application is relatively well designed, but the implementation is chaotic in some points (especially older code). There are unit tests only for more recent code. When this project started, we didn't have the habit of doing tests. Documentation and comments are incomplete. The application is both large and complex. The client has written down almost every detail about his project, in a very clear and "programmer-friendly" way. Is it a good idea to add a person now? If so, what can we do in order to help the new developer integrate into the team?

  • Operating System not Found after installing Ubuntu in a Sony Vaio

    - by diego8arock
    I just bought a Sony Vaio SVS15115FLB that came with Windows 7, after enjoying the PC graphic power for a little, I decided it was time to install Ubuntu 12.04. First, I inserted a USB stick, reboot, press F11 but a message saying that no OS was found on the USB, so then I used a live CD. It booted fine and I installed Ubuntu, then when it was time to restart the PC, it didn't boot to GRUB but it went straight to Windows and it began an startup error and was looking for a solution, after it was done, it restarted and then it booted again to Windows and to the same start up error solution thing. I freaked out, so I booted again the Ubuntu live CD, and installed Ubuntu over everything, after it installed I rebooted and then a message appeared saying Operating system Not Found, and I have no idea why. So I Googled again and found this post on Boot Partition, I did everything exactly on that post, but it didn't work (by the way, this was the message): The boot files of [Ubuntu 12.04 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. It appeared the first time, then I did it all again and then it was gone. I rebooted and nothing, the same Operating System not found message appeared. So I decided to create a partition for Windows, hoping for something, but the message still appears. I really have no idea what to do, but there is something odd, if I insert the USB stick containing Ubuntu 11.10, the message that says that there is no OS in the PendDrive flashes for a fraction of a second and the boot straight to Ubuntu 12.04 without problems (and booted to Windows when I installed it, ignoring Ubuntu), right now I'm using it like that, but its pretty annoying. Can anyone advise me how to fix this? I'm no expert on this kind of things (boot, GRUB, recovery and stuff like that).

  • 14.04.1 LTS 64 bit from USB does not see my windows 7 when I go to install it

    - by W J
    I suppose this is as much a question as a heads up/warning 14.04.1 LTS only gave me the option of writing over everything on one of my windows 7 machines. If I'd pushed the wrong button and continued I would have lost some mighty important items. On a similar windows laptop I succesfully installed 14.04.1 LTS 32 bit alongside windows 7 rather easily ( and I dig it!), there was a prompt in that case that let me select to install it alongside my windows OS.Yikes, not in this case. This laptop was formatted NTFS, the Ubuntu usb pendrive I formatted fat32. could be a clue? It looks like there is an advanced install ubuntu, but I am not that advanced. I may try to use windows diskformat (What fdisk is gone?) to make a partition, then see if the ubuntu on my usb stick "sees" my windows. If anybody has a better plan let me know. Mahalo AHA!? p.s. its a SSD harddrive, perhaps thats the crux?
