Taming googlegroups for those without Gmail Account

I have recently migrated my primary email address to my own domain and started using it for all communication purposes. One of the main thing is to subscribe to various Google Groups which GNU/Linux User’s Groups under FSMK have. The straight forward way, you would think, would be to just search for the groups in groups.google.com website, then there should be a subscribe button where you would enter your email address and then you should receive a email to confirm that you want to subscribe. This is what most of the mailing lists software would do. However not Google Groups. If you want to subscribe to Google Groups, when you click to join the group, it asks you to sign in a Google Account, hence any non-google account wont be able to subscribe to a group.

The other way is to request the group admins to add your email address in the group, this will not work always as most of the times I wouldnt even know the admins of the group. Also it means that you now have to depend on the other person to find time to add you which will be slow. Idea of public mailing lists is that anyone interested should be able to subscribe. Unfortunately google does a reasonable job in ensuring it becomes very difficult for you unless you have a Google Account.

So I found out a more difficult way to subscribe/unsubscribe google groups and this is again borrowed from traditional mailing lists softwares.

If you know the google group’s mailing address, say

glugdsce@googlegroups.com

You can subscribe to the group, by sending a mail to

glugdsce+subscribe@googlegroups.com

To unsubscribe, send a mail to

glugdsce+unsubscribe@googlegroups.com

Similarly, to directly visit the page of the group in a browser, you can use the following link

https://groups.google.com/forum/#!forum/glugdsce

In all above cases, just remove glugdsce with the name of the group that you are interested in.

Overall, I think Google Groups continue the evils of Google and if you are a well established group/community, it is always better to host your own mailing list and move out of Google Groups as soon as possible.

split and join huge files

I recently has asked my friend to download edubuntu9.10 iso . It was a 3.4 gb iso. After he finished downloading when i had to transfer it to my system, we faced a small problem. His LAN card was not working and we had only 1gb pen drive. So the only option we had was to split the iso into files of size 1gb and then transfer them using pen drive.

command to split a huge file into smaller file.

split -b 1G

is the prefix of the smaller files that will be created.

After I split the files, i transfered each file in to my system and then joined the files using a very simple “cat” command.

Join the files splitted by the above commad.

$cat aa bb cc dd>huge-filename

The above command will join all the files and create the file huge-filename.

I need to test whether the order of the smaller files matters in the cat command. Logic says that it should matter. lemme check it out.

Confirmed it. The order of the smaller files is very importent to get back the original file.
