Recovering corrupted eclipse workspace

It has happened to me sometimes when Eclipse has crashed or if I had to kill it after it becomes unresponsive that the workspace was corrupted and that I was unable to launch the same workspace. Too lazy to create a new workspace and import all my projects again, one trick that did work was to go into the workspace folder and remove the following file:

<my_workspace_name>/.metadata/.plugins/org.eclipse.core.resources/.snap

I was than able to start eclipse again and find all my projects in it.

Soving AccessDenied on Google Cloud Storage domain mapping

As I was facing this again trying to create amp pages for my main site www.tekartik.com , here is a concrete example for my changes Adding the proper DNS redirection in my domain provider (OVH in my case) www.tekartik.com. CNAME c.storage.googleapis.com. This was first giving the error: <Error>   <Code>AccessDenied</Code>   <Message>Access denied.</Message>   <Details>Anonymous callers do not have storage.objects.list access to bucket www.tekartik.com.</Details> </Error> the solution was to configure my bucket as a website configuration : gsutil web set -m index.html -e 404.html gs://www.tekartik.com And to make all files I add public by default and not worry about ACL anymore, I can use gsutil defacl ch -u AllUsers:R gs://www.tekartik.com To make previous imported files public, I can use gsutil -m acl -r set public-read gs://www.tekartik.com

Simple Samba setup on Lubuntu

I have a simple lubuntu server where I setup a ssh server. While it is sufficient to access a driver/folder from another linux machine using sftp, it is a pain from Windows & Mac, so unfortunately, samba is still needed here. For simplicity I needed only one samba user that I could map to a single user on my lubuntu machine Following the various tutorial I ended up doing this with simple commands Install samba $ sudo apt-get install samba Add myuser to the samba $ sudo smbpasswd -a myuser Export the drive I needed (no guest user) $ sudo vi /etc/samba/smb.conf to add the following export (no real option needed here) [files] path = /media/music/files writeable = yes save and Restart samba $ sudo service smbd restart
