Installing datacommons from sunlight

- by Newben

I know strictly nothing from python and I am installing datacommons from the sunlightlabs. So I followed step by step the README.md https://github.com/sunlightlabs/datacommons First, it is said in the doc to add to the virtualenv dc_data, dc_matcchbox but I didn't find them. But I went to the final step to run ./manage.py runserver so I had the following message : (datacommons)newben@newben-VirtualBox:~/share-ubuntu/sunlightlabs-datacommons-e3ff1a3$ ./manage.py runserver fatal: Not a git repository (or any parent up to mount parent /home/mbenchoufi) Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set). Error: Can't find the file 'settings.py' in the directory containing './manage.py'. It appears you've customized things. You'll have to run django-admin.py, passing it your settings module. (If the file settings.py does indeed exist, it's causing an ImportError somehow.) In the 'sunlightlabs-datacommons-e3ff1a3' folder, I downloaded and put the files from github. By the way I didin't understand how to deal with the settings file. Could someone help me understand how to install datacommons ?

My VB crushes for a pre-header non recognized

- by Newben

I have a great problem to deal : no access anymore to Ubuntu through my VirtualBox. I always have the same message Session failed to Open Could not open the medium '/Users/me/VirtualBox VMs/Ubuntu/Ubuntu.vdi'. VDI: error reading pre-header in '/Users/me/VirtualBox VMs/Ubuntu/Ubuntu.vdi' (VERR_DEV_IO_ERROR). VD: error VERR_VD_VDI_INVALID_HEADER opening image file '/Users/me/VirtualBox VMs/Ubuntu/Ubuntu.vdi' (VERR_VD_VDI_INVALID_HEADER).

But I can't open my 6go sized file nor with HexFiend, nor with 0exED... And if I did, how do I find the pre-header ?

Trying to get back seamless mode on my VirtualBox

- by Newben

I am trying from some days to activate again the seamless mode on my VirtualBox(using Ubuntu 12.04 on an osx device), which was correctly set till now but which isn't working anymore. I have had already this problem but then I had to reinstall a new disk on my VB. I tried everything I know : installing it by clicking on the 'devices' item in the nav bar of VB's app, I created a new dir in /media and then tried to mount the /dev/sr0. When running sh ./VBoxLinuxAdditions.run, it installed correctly But when rebooting my machine, I always have the same problem. Does anybody knows how to activate again Seamless Mode ?

Git clone on an ovh host server

- by newben

I want to do a git-clone from an ssh connection, on an ovh host-server, but it does not work: Here's the command I entered: git clone ssh :/ / [email protected] / www / (and all variations /. Git / www / .git, / www / .git / ... ) This is the message that I invariably get: fatal: '/ www': unable to chdir or not a git archive fatal: The remote end hung up unexpectedly Moreover, the command git clone "ssh :/ / [email protected] / ~ / forumdesthinktanks.git" responded with: Permission denied, please try again. [email protected] 's password: While the ftp password is correct. Finally, the commands git clone ssh :/ / [email protected] /. Git and git clone ssh :/ / [email protected] / ~ / forumdesthinktanks.git do not work (until the terminal's time out). I'm using a terminal from my Mac.

connection to apache server switches sockets connection

- by Newben

I have just post a question but I post an other one because the problem is not the one I had in thought when asking the latter. So, I am running some rails app on osx, when I run rails s, everything works fine. If I shut down the apache server (mamp) and if I run rails s again, I have this message Can't connect to local MySQL server through socket '/Applications/MAMP/tmp/mysql/mysql.sock', which for sure is normal. For info, my mamp server is running, and the connection must pass through /Applications/MAMP/Library/bin/mysql, so I aliased it by setting in my bash profile : alias mysql="/Applications/MAMP/Library/bin/mysql" Now, when I launch a rails generate command type, I get this message : /$root/vendor/bundle/ruby/2.0.0/gems/mysql2-0.3.11/lib/mysql2/client.rb:44:in `connect': Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) (Mysql2::Error) So how it can be ?
