  Hi, My RoR App use rails 2.1.2 When I run rake db:migrate --trace I get the following error, Any idea? ** Invoke db:migrate (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute db:migrate rake aborted! uninitialized constant Encoding /Users/denisjacquemin/Documents/code/projects/BmfOnRails/vendor/rails/activesupport/lib/active_support/dependencies.rb:278:in `load_missing_constant' /Users/denisjacquemin/Documents/code/projects/BmfOnRails/vendor/rails/activesupport/lib/active_support/dependencies.rb:467:in `const_missing' /Users/denisjacquemin/Documents/code/projects/BmfOnRails/vendor/rails/activesupport/lib/active_support/dependencies.rb:479:in `const_missing' /Library/Ruby/Gems/1.8/gems/sqlite3-0.0.8/lib/sqlite3/encoding.rb:9:in `find' /Library/Ruby/Gems/1.8/gems/sqlite3-0.0.8/lib/sqlite3/database.rb:66:in `initialize' /Users/denisjacquemin/Documents/code/projects/BmfOnRails/vendor/rails/activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb:13:in `new' /Users/denisjacquemin/Documents/code/projects/BmfOnRails/vendor/rails/activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb:13:in `sqlite3_connection' /Users/denisjacquemin/Documents/code/projects/BmfOnRails/vendor/rails/activerecord/lib/active_record/connection_adapters/abstract/connection_specification.rb:292:in `send' /Users/denisjacquemin/Documents/code/projects/BmfOnRails/vendor/rails/activerecord/lib/active_record/connection_adapters/abstract/connection_specification.rb:292:in `connection=' /Users/denisjacquemin/Documents/code/projects/BmfOnRails/vendor/rails/activerecord/lib/active_record/connection_adapters/abstract/connection_specification.rb:260:in `retrieve_connection' /Users/denisjacquemin/Documents/code/projects/BmfOnRails/vendor/rails/activerecord/lib/active_record/connection_adapters/abstract/connection_specification.rb:78:in `connection' /Users/denisjacquemin/Documents/code/projects/BmfOnRails/vendor/rails/activerecord/lib/active_record/migration.rb:408:in `initialize' /Users/denisjacquemin/Documents/code/projects/BmfOnRails/vendor/rails/activerecord/lib/active_record/migration.rb:373:in `new' /Users/denisjacquemin/Documents/code/projects/BmfOnRails/vendor/rails/activerecord/lib/active_record/migration.rb:373:in `up' /Users/denisjacquemin/Documents/code/projects/BmfOnRails/vendor/rails/activerecord/lib/active_record/migration.rb:356:in `migrate' /Users/denisjacquemin/Documents/code/projects/BmfOnRails/vendor/rails/railties/lib/tasks/databases.rake:99 /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:636:in `call' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:636:in `execute' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:631:in `each' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:631:in `execute' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:597:in `invoke_with_call_chain' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/monitor.rb:242:in `synchronize' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:590:in `invoke_with_call_chain' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:583:in `invoke' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:2051:in `invoke_task' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:2029:in `top_level' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:2029:in `each' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:2029:in `top_level' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:2068:in `standard_exception_handling' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:2023:in `top_level' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:2001:in `run' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:2068:in `standard_exception_handling' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:1998:in `run' /Users/denisjacquemin/.gem/ruby/1.8/gems/rake-0.8.7/bin/rake:31 /usr/bin/rake:19:in `load' /usr/bin/rake:19 My database.yml development: adapter: sqlite3 database: db/development.sqlite3 pool: 5 timeout: 5000 thanks

• Dealing with HTTP content in HTTPS pages

  - by El Yobo

  We have a site which is accessed entirely over HTTPS, but sometimes display external content which is HTTP (images from RSS feeds, mainly). The vast majority of our users are also stuck on IE6. I would both of the following Prevent the IE warning message about insecure content Present something useful to users in place of the images that they can't otherwise see; if there was some JS I could run to figure out which images haven't been loaded and replace them with an image of ours instead that would be great. I suspect that the first aim is simply not possible, but the second may be sufficient. A worst case scenario is that I parse the RSS feeds when we import them, grab the images store them locally so that the users can access them that way, but it seems like a lot of pain for reasonably little gain.

• Lost all privileges since upgrading to 13.10

  - by Chris Poole

  Since upgrading to 13.10, I no longer have the 'privileges' to do the following things: Mount USB/CDROM drives Run software centre or software updater Press the GUI shut down or restart buttons Unlock my account in the 'settings - user accounts' section (padlock is greyed out) Also, when logging on as a guest user I get error messages relating to Compiz crashing with SIGSEGV and it hangs on a blank wallpaper screen.

• Degrading administrative privilege to standard with single admin user account

  - by Vivek S Panicker

  I recently met with a severe issue with user accounts. In my system, there is only administrator user named vivek. I added another user with name vivi and changed its privilege to administrator. After clicked on my username, vivek,and changed its privilege to standard. Since vivek is being the current user, I dropped with all administrator privileges. No password was set for the new administrator user vivi and hence it was disabled by default. I no longer access to any administrative activities. Later I corrected this by editing etc/group file. Isn't this a severe bug? Being the current administrator user, how could I degrade myself to a standard user and got out from administrator's seat? I did not get any warning messages indicating no other administrators exists to manage my system. I suggest this warning should be included there in user accounts when an administrator user changes his privilege without any enabled administrators. Your thoughts?

• Samba Server Make Multiple User Permissions Profiles

  - by Scriptonaut

  I have a Samba file server running, and I was wondering how I could make multiple user accounts that have different permissions. For example, at the moment I have a user, smbusr, but when I ssh to the share, I can read, write, execute, and even navigate out of the samba directory and do stuff on the actual computer. This is bad because I want to be able to give out my IP so friends/family can use the server, but I don't want them to be able to do just anything. I want to lock the user in the samba share directory(and all the sub directories). Eventually I would like several profiles such as (smbusr_R, smbusr_RW, smbguest_R, smbguest_RW). I also have a second question related to this, is SSH the best method to connect from other unix machines? What about VPN? Or simply mounting like this: mount -t ext3 -o user=username //ipaddr/share /mnt/mountpoint Is that mounting command above the same thing as a vpn? This is really confusing me. Thanks for the help guys, let me know if you need to see any files, or need anymore information.

• Ubuntu no longer prompts for root privilege (but doesn't give it either)

  - by Elad Avron

  So on 14.04 LTS I was playing around with some settings to solve another problem, and somehow managed to screw things up and now Ubuntu no longer asks for root privileges before trying to perform administrative actions. The catch is that my user does NOT have them by default, which means those actions ALL fail. I can still run "sudo " from terminal and it'll ask for my password and work fine, but any GUI that requires root just fails without asking anything. Any ideas what I did wrong and how to solve it? Thanks in advance.

• Why there are many guest accounts?

  - by Radu Radeanu

  After I saw this answer, I realized that there are many guest accounts on my system: grep guest /etc/passwd guest-jzXeRx:x:117:127:Guest,,,:/tmp/guest-jzXeRx:/bin/false guest-l5dAPU:x:118:128:Guest,,,:/tmp/guest-l5dAPU:/bin/false guest-FdSAkw:x:119:129:Guest,,,:/tmp/guest-FdSAkw:/bin/false guest-eBU0cU:x:121:131:Guest,,,:/tmp/guest-eBU0cU:/bin/false Moreover, in this moment there is nobody logged as guest, but if somebody will login as guest, a new guest account is created - why, since there are already other guest accounts? After the new guest will log out, his account will be deleted. But why the other guest accounts remain? For what use/purpose? It doesn't mind me at all this guest account, but I want to know if it is okay to delete them manually.

• Debugging/Logging Techniques for End Users

  - by James Burgess

  I searched a bit, but didn't find anything particularly pertinent to my problem - so please do excuse me if I missed something! A few months back I inherited the source to a fairly-popular indie game project and have been working, along with another developer, on the code-base. We recently made our first release since taking over the development but we're a little stuck. A few users are experiencing slowdowns/lagging in the current version, as compared to the previous version, and we are not able to reproduce these issues in any of our various development environments (debug, release, different OSes, different machines, etc.). What I'd like to know is how can we go about implementing some form of logging/debugging mechanism into the game, that users can enable and send the reports to us for examination? We're not able to distribute debug binaries using the MSVS 2010 runtimes, due to the licensing - and wouldn't want to, for a variety of reasons. We'd really like to get to the bottom of this issue, even if just to find out it's nothing to do with our code base but everything to do with their system configuration. At the moment, we just have no leads - and the community isn't a very technically-savvy one, so we're unable to rely on 'expert' bug reports or investigations. I've seen the debug logging mechanism used in other applications and games for everything from logging simple errors to crash dumps. We're really at a loss at this stage as to how to address these issues, having been over every commit to the repository from the previous to the current version and not finding any real issues.

• Easy user management on html site?

  - by James Buldon

  I hope I'm not asking a question for which the answer is obvious...If I am, apologies. Within my html site (i.e. not Wordpress, Joomla, etc.) I want to be able to have a level of user management. That means that some pages I want to be only accessible to certain people with the correct username and password. What's the best way to do this? Are there any available scripts out there? I guess I'm looking for a free/open source version of something like this: http://www.webassist.com/php-scripts-and-solutions/user-registration/

• Backup all home folders on usb disk and accessibility

  - by PatrickV

  I am using Ubuntu 12.04 and have multiple family members working on it with there own home folder. I have an USB disk and want to use it to backup my home folders. Trying this, I got some questions. When my disk auto mount, it is not visible for each user. It seams to be visible for the user the time I connect the usb disk. I want to create one folder per home on the usb disk to backup the data to. But when I format the disk in EXT4 or FAT for example it is Read Only. How can I format the disk so it is accessible to every user. Best Regards, Patrick

• Adding user to chroot environment

  - by Neo

  I've created a chroot system in my Ubuntu using schroot and debrootstrap, based on minimal ubuntu. However whenever I can't seem to add a new user into this chroot environment. Here is what happens. I enter schroot as root and add a new user 'Bob'.(Tried both adduser and useradd commands) The username 'Bob' lists up in /etc/passwd file and I can 'su' into the user 'Bob'. So far so good. When I log out of schroot, and re-enter schroot, the user 'Bob' has vanished!! There is no mention of Bob in /etc/passwd either. How do I make the new user permanent?

• Design Application to "Actively" Invite Users (pretend they have privileges)

  - by user3086451

  I am designing an application where users message one another privately, and may send messages to any Entity in the database (an Entity may not have a user account yet, it is a professional database). I am not sure how to best design the database and the API to allow messaging unregistered users. The application should remain secure, and data only accessed by those with correct permissions. Messages sent to persons without user accounts serve as an invitation. The invited person should be able to view the message, act on it, and complete the user registration upon receiving an InviteMessage. In simple terms, I have: User misc user fields (email, pw, dateJoined) Entity (large professional dataset): personalDetails... user->User (may be null) UserMessage: sender->User recipient->User dateCreated messageContent, other fields..... InviteMessage: sender->User recipient->Entity expiringUrl inviteeEmail inviteePhone I plan to alert the user when selecting a recipient that is not registered yet, and inform that he may send the message as an invitation by providing email, phone where we can send the invitation. Invitations will have a unique, one-time-use URL, e.g. uuid.uuid4(). When accessed, the invitee will see the InviteMessage and details about completing his/her registration profile. When registration is complete, InviteMessage details to a new instance of UserMessage (to not lose their data), and assign it to the newly created User. The ability to interact with and invite persons who do not yet have accounts is a key feature of the application, and it seems better to separate the invitation from the private, app messages (easier to keep functionality separate, better if data model changes). Is this a reasonable, good design? If not, what would you suggest? Do you have any improvements? Am I correct to choose to create a separate endpoint for creating invitations via the API?

• What was the first consumer-oriented hardware/software solution?

  - by Maksee

  We all know the story of the personal computer as a consumer-oriented product. But I just thought that real end user solution should have appeared before that time. So a product that was probably expensive, but allowed using it as a service charging for it, for example computer-terminal for transport time-table access or game machine. On the other site, the video terminals as we know them appeared not so long ago. So if there was something like this, this could be hardware/software most likely offering no interactivity, but probably printing some information based on user actions.

• Authenticate user that has no password?

  I've set up my user account so that no password is required to login and I need to install some updates. However when prompted for the password, it says authentication failed if I leave the box blank. I don't have a password, how am I supposed to authenticate? EDIT I tried the method in Reset lost administrative(root) password but it came out with an error: Authentication token manipulation error password unchanged. What does this mean?

• I'm in a group but can't create or modify files

  - by dac

  I have two user accounts. Let's say one is User1 and the other is User2. Both of these accounts are in the "root" group. I made a folder with some files in it. The owner is User1 and the group is root. The permissions are set so the group "root" can create and delete files. However, when I log in as User2, I can only access files. User2 is in the "root" group for sure, and when I right-click on the folder in Nautilus, and then PropertiesPermissions, it says there that the "root" group can create and delete files. What's going on? edit: Logged out and then back in, and, I don't know why, everything works now...

• 12.04 scanner works fine as super-user but is not recognised as a normal user

  - by Eugénio Outeiro

  I have an all-in-one printer Epson SX130, wich I have just tried to install. I got the printer working with no problem, but I couldn't set the scanner up. I have had another all-in-one printer before (Brother DCP-125C), and had just the same problem, so I decided to try the same trick I used to do then, running the scanning program as super-user: $sudo simple-scan and $ sudo xsane Once again, it worked just fine, and I could use the scanner. Anyhow, this solution is a little annoying, because I also have to change the permissions to the files I get scanning like this. I have been searching the internet for solutions and got to know this must have something to do with user groups permissions, but couldn't find a satisfying solution. Is there anyone with an idea? Thank you in advance.

• Video crashes with 10.10

  - by John Mahon

  I have installed both the 64bit and 32 bit versions of 10.10 on my Compaq Presario PC. I first installed the 64 bit version of the OS.The video often crashed when switching user. It also went haywire occasionally when I visited some web-sites. I read that there may be some problems with the 64 bit OS. So I installed the 32 bit version on another disk. This version seemed even less well behaved. HP's model number for the computer is SR1838NX. The hardware is listed at http://bizsupport1.austin.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c00628274&lang=en&cc=us&contentType=SupportFAQ&prodSeriesId=1841793&prodTypeId=12454&printver=true#A0 I think the important info is that the chip set is "ATI Radeon Xpress 200" and the processor is "Athlon 64 (S) 3700+ 2.2 GHz" Has anyone else had video problems with similar machines? Is there a work around or an update? I have had previous versions of Ubuntu working on this machine and other flavors of Linux as well. Thanks in advance. John

• How do I unlock a user account?

  - by John Kotrla

  I've been to system settings and to User Accounts. My account is the only one on the system and I have previously been able to UnLock the screen so that I could set my account to login without password prompt. That didn't make any effect on the system. I still have to enter a password to log in, but now I can't unlock the User Accounts dialog to make any changes at all.

• How to create a user with root privileges in bash?

  - by George Edison

  I have run the following commands: sudo groupadd -r testgroup sudo useradd -g testgroup -M -r testuser Notice the -r option, which according to the man page: -r     Create a system account. Assuming I have a user account with root privileges, I then run: sudo -u testuser cat /dev/input/mouse0 However, I get: cat: /dev/input/mouse0: Permission denied Running the same command as root provides the expected output (garbled output from the mouse driver). How can I create a user with root privileges?

• Is it possible to allow the user to access the 'Volumes' without asking the Administrator's password?

  - by Tom

  Am the administrator of my Ubuntu system. Recently I added a new user account. But when ever the user tries to access or open the 'Volumes'(Drives where movies, songs and other files are stored) it asks for the Administrator's password. I created the user account to my other family members and I don't want to tell them my password. So is it possible to allow them to access the Volumes without asking Administrator's password ? UPDATE : Ubuntu was installed alongside Windows in my system. I will provide a screenshot of the Volume details -

• Should you put personal beliefs in your program?

  - by TheLQ

  Recently I've found two examples of programmer's personal beliefs in programs that have removed or crippled useful functionality uTorrent using KB (rarely used) vs Kb (what most ISPs and other programs use as their metric) in their current connection speed. Various attempts by others and me to give options to at least give an option to show in Kb have ended with "ISPs should use KB" Kleopatra (gpg4Win key manager) not having PGP Key Pictures since they "give a false sense of security" and "increase the size of certificates". While the latter is true, the former is debatable. Both of these hurt the program and its usefulness to me. uTorrent's forums used to be filled with people saying they have 10 Mb download pipe but uTorrent only goes up to 2 MB (not knowing that Mb != MB), and with feature requests to show in Mb. Kleopatra has lost usefulness to me since I don't have the functionality to add pictures to PGP keys. These all are political statements; developers attempting to make change in, in their minds important, issues. But should this come at a cost to end user functionality? If a programmer heavily believes X but everyone else believes Y, should the programmer refuse to add support for Y because in their mind X is horrible? In short, should a programmer make political statements in their program?
