Windows Recovery from Grub messed up my computer?

- by Hudson Worden

Ok so I'm a noob when it comes to Operating Systems and I think I really messed up this time. So I have a laptop that dual boots Windows 7 and Linux Mint 11. I was trying to boot into Windows 7 but it would just have a black screen with a blinking cursor. So I turned off my computer and tried again. Still a black screen with a cursor. So I thought "well it must be broken somehow and I remembered seeing something like 'Windows Recovery' from the boot menu so I should try it." So when I turned on my computer a third time I selected 'Windows Recovery' (Something like that I can't remember exactly what it was called). After I had selected that I got a white Windows window that said in big red letters "ERROR". I turned off my computer again a turned it back on expecting the Grub menu to reappear. I was wrong. Instead I am greeted with error: no such partition grub rescue. Then I put in a live CD for ubuntu 11.04 and tried looking at my partitions using the disk manager. Looking at my partitions I notice that there isn't a Linux partition anymore and in its place is a unallocated space partition yet the Linux Swap partition is still there. My windows partition is still fine and I can access the files in it. If you understand what has happened, is there anyway I can get my files back? I don't care about reinstalling the OS again. I just want those files that are in the Linux Mint partition.

Working with Git on multiple machines

- by Tesserex

This may sound a bit strange, but I'm wondering about a good way to work in Git from multiple machines networked together in some way. It looks to me like I have two options, and I can see benefits on both sides: Use git itself for sharing, each machine has its own repo and you have to fetch between them. You can work on either machine even if the other is offline. This by itself is pretty big I think. Use one repo that is shared over the network between machines. No need to do git pulls every time you switch machines, since your code is always up to date. Never worry that you forgot to push code from your other non-hosting machine, which is now out of reach, since you were working off a fileshare on this machine. My intuition says that everyone generally goes with the first option. But the downside I see is that you might not always be able to access code from your other machines, and I certainly don't want to push all my WIP branches to github at the end of every day. I also don't want to have to leave my computers on all the time so I can fetch from them directly. Lastly a minor point is that all the git commands to keep multiple branches up to date can get tedious. Is there a third handle on this situation? Maybe some third party tools are available that help make this process easier? If you deal with this situation regularly, what do you suggest?

No sound Ubuntu 12.04 through HDMI

- by MikeMan

Specs: Asus G73JH i7/720; ATI Mobility 5870 I have read through a lot of threads on getting HDMI sound to work and non of them have fixed my issue. Granted I am very new to Linux and know only the GUI aspect of what it does from finding similarities that Windows 7 has. I would like to become a Linux Power User and I figured this would be a good step to get started. I was able to successfully install my graphics driver and it shows in use. I connect the HDMI to my HD TV and I get no sound. I don't care about auto switch for sound, that would be great but not necessary. I just want my sound to work through the HDMI. What I have tried: Changed GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1" pact set-card-profile 0 output:hdmi-surround Failure: no such entity Sound Settings: Right-click Sound indicator ? Sound Settings ? Output Tab, and set Digital Output (S/PDIF) Built in Audio Speakers Built in Audio I only get 2 settings. If I right-click the area below those 2 in the "play sound through" box, I get no "show hidden devices". I am also doing all this with the HDMI connected to eliminate any possibility for error.

Alternatives to time tracking methodologies [closed]

- by Brandon Wamboldt

Question first: What are some feasible alternatives to time tracking for employees in a web/software development company, and why are they better options Explanation: I work at a company where we work like this. Everybody is paid salary. We have 3 types of work, Contract, Adhoc and Internal (Non billable). Adhoc is just small changes that take a few hours and we just bill the client at the end of the month. Contracts are signed and we have this big long process, the usual. We figure out how much to charge by getting an estimation of the time involved (From the design and the developers), multiplying it by our hourly rate and that's it. So say we estimate 50 hours for a website. We have time tracking software and have to record the time in 15 we spend on it (7:00 to 7:15 for example), the project name, and give it some comments. Now if we go over the 50 hours, we are both losing money and are inefficient. Now that I've explained how the system works, my question is how else can it be done if a better method exists (Which I'm sure one must). Nobody here likes the current system, we just can't find an alternative. I'd be more than willing to work after hours longer hours on a project to get it done in time, but I'm much inclined to do so with the current system. I'd love to be able to sum up (Or link) to this post for my manager to show them why we should use abc system instead of this system.

Designing object oriented programming

- by Pota Onasys

Basically, I want to make api calls using an SDK I am writing. I have the following classes: Car CarData (stores input values needed to create a car like model, make, etc) Basically to create a car I do the following: [Car carWithData: cardata onSuccess: successHandler onError: errorHandler] that basically is a factory method that creates instance of Car after making an API call request and populating the new Car class with the response and passes that instance to the successHandler. So "Car" has the above static method to create that car, but also has non-static methods to edit, delete cars (which would make edit, delete API calls to the server) So when the Car create static method passes a new car to the successHandler by doing the following: successHandler([[Car alloc] initWithDictionary: dictionary) The success handler can go ahead and use that new car to do the following: [car update: cardata] [car delete] considering the new car object now has an ID for each car that it can pass to the update and delete API calls. My questions: Do I need a cardata object to store user inputs or can I store them in the car object that would also later store the response from all of the api calls? How can I improve this model? With regards to CarData, note that there might be different inputs for the different API calls. So create function might need to know model, make, etc, but find function might need to know the number of items to find, the limit, the start id, etc.

Approaches for a clickable map of nations (such as a Risk game) with Spritekit

- by Vukovitch

I would like to create a political map where each country is clickable by tapping but I'm not sure the best way to determine which nation was selected. Imagine Risk where each country can be individually clicked to bring up additional information. My current approach is to make a sprite for each nation where every image is the size of the screen The images are mostly transparent except for the country, that way when all of the images are displayed the countries are in the correct place relative to one another. To determine if a click occurs on an individual country I look to see if the tapped location is a non transparent pixel and check that the sprite's name is one of the countries. Additionally the nation needs to glow or something when tapped as an indicator, however my current solution is yet another sprite that is displayed. This seems like a terrible approach and I was wondering what other solutions might achieve the same results. I'm pretty new to SpriteKit so I'm not entirely sure. The other idea I had was creating a single texture where each country is a different shade of gray, then when I get the tap location I do a lookup on the color at that location and get the corresponding country. However, I'm not sure how to create a hilight or glowing country effect with that method.

two thoughts about career excellence

- by john.rose

I love Dickens, warts and all. Sometimes he is sententious, and (like the mediocre modern I am) at such points I am willing to listen non-ironically. This bit here struck me hard enough to stop and write it down: I mean a man whose hopes and aims may sometimes lie (as most men's sometimes do, I dare say) above the ordinary level, but to whom the ordinary level will be high enough after all if it should prove to be a way of usefulness and good service leading to no other. All generous spirits are ambitious, I suppose, but the ambition that calmly trusts itself to such a road, instead of spasmodically trying to fly over it, is of the kind I care for. It is Woodcourt's kind. (John Jarndyce to Esther Summerson, Bleak House, ch. 60) Woodcourt is, of course, one of the heroes of the story. It is a heroism that is attractive to me. Here is a similar idea, from the Screwtape Letters. In the satirically inverted logic of that book, the “Enemy” is God, the enemy of the devils but the author of good: The Enemy wants to bring the man to a state of mind in which he could design the best cathedral in the world, and know it to be the best, and rejoice in the, fact, without being any more (or less) or otherwise glad at having done it than he would be if it had been done by another. (C.S. Lewis, Screwtape Letters, ch. 14) Though I will be happy with a good Bazaar, I also dream of Cathedrals. Put whatever name you like on it, as long as I get some part in the fun of building a good one.

Partition tool with console UI (as in server installation)?

- by lepe

Back in 2006, Ray (3DLover) posted the same question in: http://ubuntuforums.org/showthread.php?t=309680 but none of the answers were really useful. Now with a little help from AskUbuntu community, I would like to repeat his question again to see if this time it can be answered correctly. So this is the question (and what I wish too): I'm looking for a UI tool for managing partitions in a console. I have installed Ubuntu Server, so I don't have X Windows at all. fdisk and sfdisk are entirely command line. parted is slightly better, but it's not really a UI. cfdisk has somewhat of a UI, but it only works on one disk at a time, and there's no advanced options like configuring LVM or RAID. Just partitioning. I love the partition tool that is available during the OS install procedure. You can partition, configure RAID's and LMV sets. It can format the partitions with several different file systems, it can set labels, mount options and it can insert your volumes into your fstab. Is this tool available as a stand-alone program? I can't find it anywhere. I think it's called parted_server, but I can't find much information about where to get it. In the past, I have run the Ubuntu install procedure just to use the partition manager that comes with it. (canceling the install after making my partition edits) Anyone help me on this? Thanks -Ray Thanks in advance.

Installing a new ASP.NET 4.0 site on a Windows 2008 server.

- by TATWORTH

I have been specifically requested to blog about getting an ASP.NET 4.0 site working on a Windows 2008 server that has never run a 4.0 web site before. Make sure the 4.0 framework is installed on the server! Patch it will ALL the security patches have been applied. ((for a live server, make sure that you tested the patches on your development server first) You will find the HTTP Log status codes at http://support.microsoft.com/kb/943891 - they are very important in understandign the IIS logs) After installing, turn on 4.0, by doing the following: Start the Internet Information Services (IIS Manager) Select the server node in the connections pane. (this is the node above Application Pools, FTP Sites and Server Farms) Double click the ISAPI and CGI Restrictions item in the centre pane You should see 1 or 2 ASP.NET v4.0.30319 entries, select Enable in the Actions pane for all of them. ASP.NET 4.0 should now run! Remeber after creating your new 4.0 ASP.NET site. select the Sites node and find out the Id of it. By default, the IIS logs are at C:\inetpub\logs\LogFiles and if your site is say 21, then the logs will be created in the W3SVC21 sub-directory. The key point about using these logs is that in the event of an error when trying to start the site for the first time, the log will contain the status code and the sub-code. By having the full code and sub-code, set up issues can be resolved in minutes instead of hours.

Use the “using” statement on objects that implement the IDisposable Interface

- by mbcrump

From MSDN : C#, through the .NET Framework common language runtime (CLR), automatically releases the memory used to store objects that are no longer required. The release of memory is non-deterministic; memory is released whenever the CLR decides to perform garbage collection. However, it is usually best to release limited resources such as file handles and network connections as quickly as possible. The using statement allows the programmer to specify when objects that use resources should release them. The object provided to the using statement must implement the IDisposable interface. This interface provides the Dispose method, which should release the object's resources. In my quest to write better, more efficient code I ran across the “using” statement. Microsoft recommends that we specify when to release objects. In other words, if you use the “using” statement this tells .NET to release the object specified in the using block once it is no longer needed. So Using this block: private static string ReadConfig() { const string path = @"C:\SomeApp.config.xml"; using (StreamReader reader = File.OpenText(path)) { return reader.ReadToEnd(); } } The compiler converts this to: private static string ReadConfig1() { StreamReader sr = new StreamReader(@"C:\SomeApp.config.xml"); try { return sr.ReadToEnd(); } finally { if (sr != null) ((IDisposable)sr).Dispose(); } }

How To Sync Your Shared Google Calendars with Your iPhone

- by Justin Garrison

Smartphones are essential to our daily lives. They help us stay connected and keep us organized. But when it comes to calendar syncing and Gmail there are limitations. Here’s how you can sync your shared calendars and contacts from Gmail. If you use Gmail you probably know about the ability to create and share calendars with others. They help keep groups organized and even let you subscribe to public events. When it comes to getting that information on your smartphone there are some trade offs if you are on a non-Android phone. Android phones will sync your email, contacts, and all of your calendars by just singing into your Gmail account. If you have an iPhone however, you will miss out on contact syncing if you set up your account as a Gmail account. HTG Explains: Do You Really Need to Defrag Your PC?

WIFI/LAN not working after Installing Ubuntu 13.10

- by user183025

I can't connect to my WIFI after installing Ubuntu 13.10. I tried re-installing it three times (thinking that I did something wrong during the installation) but I still can't connect to my WIFI. It just gives me the message that I'm offline and that I can't connect to my WIFI. I also tried connecting to the internet using LAN cable but with the same results. I tried google but it seems that there's no solution to this yet.... Anybody knows how to solve this? Thanks!

Using Bullet physics engine to find the moment of object contact before penetration

- by MooMoo

I would like to use Bullet Physics engine to simulate the objects in 3D world. One of the objects in the world will move using the position from 3D mouse control. I will call it "Mouse Object" and any object in the world as "Object A" I define the time before "mouse object" and "Object A" collide as t-1 The time "mouse object" penetrate "Object A" as t Now there is a problem about rendering the scene because when I move the mouse very fast, "Mouse object" will reside in "Object A" before "Object A" start to move. I would like the "Mouse Object" to stop right away attach to the "Object A". Also If the "Object A" move, the "Mouse object" should move following (attach) the "Object A" without stop at the first collision take place. This is what i did I find the position of the "Mouse Object" at time t-1 and time t. I will name it as pos(t-1) and pos(t) The contact time will be sometime between t-1 to t, which the time of contact I name it as t_contact, therefore the contact position (without penetration) between "Mouse object" and "Object A" will be pos(t_contact) then I create multiple "Mouse object"s using this equation pos[n] = pos(t-1) * C * ( pos(t) - pos(t-1) ) where 0 <= C <= 1 if I choose C = 0.1, 0.2, 0.3,0.4..... 1.0, I will get pos[n] for 10 values Then I test collision for all of these 10 "Mouse Objects" and choose the one that seperate between "no collision" and "collision". I feel this method is super non-efficient. I am not sure the way other people find the time-of-contact or the position-of-contact when "Object A" can move.

Should I indicate that the user exists or was deleted on the error page?

- by animuson

On an ordinary public website, the user's profile is always publicly visible to all visitors (such as Stack Overflow), where they can limit certain pieces of information via privacy settings or just removing the information. Now the user has decided to delete their account (in my case deactivate) so that their account doesn't technically "exist" anymore. The way my system is set up, when their account is deactivated, their username for any content connected to them just becomes "Anonymous User" as if it were a guest that posted. I feel like this could cause some confusion for other users. I'm also concerned about what kind of error to display when someone attempts to view their profile page. My gut tells me to just display a standard 404 page to hide the fact that they ever existed, but then you also have to consider that, since usernames must be unique, anyone can go to the register page and type in the username to see if it really exists or not. I have a similar problem with another website, which gives users the ability to hide their profiles from the public and only allow registered users to view it. Again it's with the dilemma of what kind of error message to display when an unregistered users attempts to view their profile with invalid permissions. So, would it be acceptable to display basic errors such as "user has been deactivated" or "you must be logged in to view this profile" in order to give other visitors some idea of why the page can't be displayed, or should I attempt to cover the user's privacy a little and just display a standard 404 without indicating in any way that the user might exist? Are there any other issues that I'm not realizing about either route? To go back to the beginning, should I even bother changing the user's name to "Anonymous User" when their account is deactivated? Would it be acceptable to just display a non-linked version of their username in place of the normal linked display name?

Upgrading Ubuntu(32 bit) 10.10 -> 11.04 fails and causes a kernel panic on boot

- by Ubuntu Upgrade

On Ubuntu 10.10 machine Upgrade to Ubuntu 11.04 using the update manager. The upgrade fails and leaves the system in an unstable state. When I reboot the system I get a kernel panic on boot. The error points to /opt/abc/runtime/lib/libc.so.6. By researching on this I found that there is a third party software abc causes problem. It has it's own runtime(libc) library. In /lib/ directory there is a link file /lib/ld-abc.so.2 ---/opt/abc/runtime/lib/ld-linux.so.2. If we rename this file to /lib/abc.so.2 or remove this file the the upgrade is success. Here is the upgrade log of where it crashes(apt-term.log) ===== Services restarted successfully.

How to automatically mount a folder and change ownership from root in virtualbox

- by Fiztban

It is my first time using virtualbox and ubuntu (14.04), I am on a host Windows 7 OS. I am trying to mount a shared folder that has files I need to access both in the virtualbox and on the windows OS. I have successfully mounted them using the vboxsf from the Guest Additions installed. To mount I used the command sudo mount -t vboxsf <dir name in vbox> <directory in linux for example I used sudo mount -t vboxsf Test /home/user/Test I found several ways of mounting the directories automatically upon startup using for example the /etc/rc.local method (here) where you modify said file appending the command to it (without sudo). Or by using the fstab method (here). I prefer the rc.local method personally. Once mounted it has permissions dr-xr-xr-x however once mounted the directory is of root ownership and chown user /home/user/Test has no effect. This means I cannot make or change files in it as a normal user. In the VirtualBox the directory to be shared is not set as read-only. Is there a way to automatically mount the shared folder and assign ownership to my non root user?

I cannot change the grub Default item from OS-1, but I can from OS-2 (dual-boot 10.04 on both)

- by fred.bear

My 10.04 system (OS-1) got into a tangle the other day, so I installed a second, dual-boot 10.04 (OS-2), so that I could trouble-shoot the hung system... In case it is relevant to my question, I'll mention that since I got OS-1 working again, it has shown a few battle wounds from its ordeal (.. actually the ordeal was mine ... trying to figure it all out ;) ... I lost some custom settings, but not all. (For the curious: the hangup was caused by rsync writing 600 GB to OS-1's 320 GB drive.. The destination drive was unmounted at the time, and rsync dutifully wrote directly to /media/usb_back; filling it to capacity... I have since, ammended my script :) Because the dual-boot MBR was prepared by OS-2, it is first on the grub list.. However, I want OS-1 to be the default OS to boot... From OS-1, I tried two methods to change the grub-menu's defaule OS. eg. Directly editing /etc/default/grub (then update-grub) Running 'Startup Manager' (then update-grub) Neither of these methods had any effect... so I started OS-2, and tried method 1... It worked! Why can I not change the grub menu from OS-1? .. or if it can be done, How?

Installing Windows from Ubuntu while booting only from the hard drive

- by WindowsEscapist

My problem is unrelated to this workaround (the question) here, but the end result is that I cannot change boot order (or use a boot menu) on my laptop. It is currently running Ubuntu 12.04 with a dual-boot to Fedora if anything goes catastrophically wrong with Ubuntu (read "if I mess it up"). I would really like to install Windows 7 (but XP would be fine) on an empty FAT32 partition I have already made because of issues with WINE-emulated programs running more slowly than under Windows. The problem is, I can only boot from my hard drive. I can boot from other devices by removing the hard drive, but this is irrelevant because SATA is non-hotpluggable (I can't plug it back in to install). Is there any way I could boot up a Windows installer CD (or other CDs)? (I know how to keep my Linux distros.) I have both the .iso's and the physical CDs (or can obtain them). This may be unneeded, but just as a disclaimer this is completely legal. The computer belongs to me, I have admin privs, etc. I'm not doing anything shady!

Audio not working in 12.10

I did a clean install of 12.10, when I open Sound Settings in gnome the only device in the list is "Dummy Output", and sound is not working. Sound worked fine out of the box in 12.04 I ran alsamixer, it says my card is "HDA Intel", and chip is "Realtek ALC880". The alsamixer playback output was set to mute at first, unmuting did not fix. I checked out the info at http://www.unixmen.com/2012003-howto-resolve-nosound-problem-on-ubuntu/ as suggested on a similar question, I've done everything there except installing the ubuntu audio dev team driver.

Starting point: I currently do development for Dynamics Ax, Android and an occasional dabble with Wordpress and Python. Soon, I'll start a project involving setting up WP on Google Apps Engine. Everything is, and should continue to, run from the same PC (running Linux Mint). Issue: I'm afraid of botching/bogging down my setup due to tinkering/installing multiple runtimes/IDE's/SDK's/Services, so I was thinking of using multiple users, each purposed to handle the task at hand (web, Android etc) and making each user as inert as possible to one another. What I need to know is the following: Is this a good/feasible practice? The second closest thing to this using remote desktops connections, either to computers or to VM's, which I'd rather avoid. What about switching users? Can it be made seamless? Anything else I should know? Update and clarification regarding VM's and whatnot: The reason I wish to avoid resorting to VM's is that I dislike the performance impact and sluggishness associated with it. I also suspect it might add a layer of complexity I wish to avoid. This answer by Wyatt is interesting but I think it's only partly suited for requirements (web development for example). Also, in reference to the point made about system wide installs, there is a level compromise I should accept as experessed by this for example. This option suggested by 9000 is also enticing (more than VM's actually) and by no means do I intend to "Juggle" JVMs and whatnot, partly due to the reason mentioned before. Regarding complexity, I agree and would consider what was said, only from my experience I tend to pollute my work environment with SDKs and runtimes I tried and discarded, which would occasionally leave leftovers which cause issues throught the session. What I really want is a set of well defined, non virtualized sessions from which I can choose at my leisure and be mostly (to a reasonable extent) safe from affecting each session from the other. And what I'm really asking is if and how can this be done using user accounts.

Can't install Ubuntu in Windows 8

- by user171635

I’ve been trying to install Ubuntu 13.04 64-bit edition on an ASUS (K53Z) laptop. I have Windows 8 64-bit installed in a non UEFI mode (I think since it starts-up with the Windows logo and I don’t have the UEFI settings). This laptop had installed Windows 7 and when I upgraded it I didn’t knew about the UEFI advantages. I tried several times to install Ubuntu from a USB device and it loads the logo and then I can’t go further in the installation. I thought it was the version of Ubuntu and tried to install Fedora (even if I personally prefer Ubuntu). I had the same problem: Fedora’s logo appears and it gets stuck. I tried also to boot from different USB devices and didn’t work either. My Bios has EFI options to boot but they were not enabled. So I tried to enable them to boot the USB in UEFI mode. A menu shows up with the options of install Ubuntu and try Ubuntu. If I click the Install or try option, I get a black screen and I can’t go further with the install (which I think is normal since I don’t have Windows 8 in EFI mode). My hypothesis is that the Bios isn’t letting Ubuntu write or read from my SSD, because the activity LED in the USB memory is on when it’s loading the installation files. Once the files are ready and the Ubuntu logo is loaded I don’t see a LED activity on neither the SSD or the USB. Thanks If I missed data you can ask me.

When creating a GUI wizard, should all pages/tabs be of the same size? [closed]

- by Job

I understand that some libraries would force me to, but my question is general. If I have a set of buttons at the bottom: Back, Next, Cancel?, (other?), then should their location ever change? If the answer is no, then what do I do about pages with little content? Do I stretch things? Place them in the lone upper left corner? According to Steve Krug, it does not make sense to add anything to GUI that does not need to be there. I understand that there are different approaches to wizards - some have tabs, others do not. Some tabs are lined horizontally at the top; others - vertically on the left. Some do not show pages/tabs, and are simply sequences of dialogs. This is probably a must when the wizard is "non-linear", e.g. some earlier choices can result in branching. Either way the problem is the same - sacrifice on the consistency of the "big picture" (outline of the page/tab + location of buttons), or the consistency of details (some tabs might be somewhat packed; others having very little content). A third choice, I suppose is putting extra effort in the content in order to make sure that organizing the content such that it is more or less evenly distributed from page to page. However, this can be difficult to do (say, when the very first tab contains only a choice of three things, and then branches off from there; there are probably other examples), and hard to maintain this balance if any of the content changes later. Can you recommend a good approach? A link to a relevant good blog post or a chapter of a book is also welcome. Let me know if you have questions.

Work @ Java shop. Tasked to redo intranet. I only know PHP - CTO says use that; Ops Says no - we have JSP, use that - Thoughts?

- by Mackysback

So I work as a project manager and was given the opportunity to redo the intranet and Internet site... I'd love to , great addition to my resume. However.... I am not familiar with java nor JSP... I am fairly proficient with PHP and MySQL ... Also my intention was to use a CMS that I have experience with, wordpress, drupal or joomla... The site would be very simple so I was thinking wordpress would be fine for this. I told management that I would need it to run on PHP and they gave me their blessing... Now the disconnect bw it and management ... I spoke with ops and they told me that we have java and JSP for that purpose although the IT guy did say "oh but I do know that php and mysql are gaining popularity" That said ... I do not understand much as far as systems architecture... We do self host and run websphere with IIS and jboss with tomcat. Any advice or suggestions? Thanks ! Is my request that unfeasible?
