YES broadband dongle with Linux



I saw a banner here at my hostel telling that there is free YES dongle for the students. So I then went to Dewan Sri Iskandar and queued up for the dongle.

After I unpacked  the box it seems the manual provides howtos for Mac and Windows only. So I googled up, searching if anyone got experience with Linux.

Turns out that YES officially provided Linux client (in BETA). Here goes the link

How to attach persistent disk on running instance at Google Compute

So I have this USD300 credit for two months period to play around with Google compute.

I had created an instance, but with very small storage, 10GB. Then I decide nothing much can be done with that, so I created a persistent disk.

Google compute's documentation is incomplete and terrible, so we need to do try and error. So this is the confirmed workable solution that I tested:

Let say we created a project name "blah-1234"
and a persistent disk name "disk-for-blah"
to be attached to a VM instance named "vm-blah"

Please replace the --zone

~$ gcloud compute instances attach-disk --project "blah-1234" vm-blah  --disk disk-for-blah --zone asia-east1-c

If everything is fine (it'll take few seconds for the disk to be attached. You'll be prompted with the following output) :

Updated [https://www.googleapis.com/compute/v1/projects/blah-1234/zones/asia-east1-c/instances/vm-blah].
