Ruby Under a Microscope

Finally, I’ve started reading the book Ruby Under a Microscope written by Pat Shaughnessy. I was eagerly waiting for this book for quite long time. When it released recently, I saw that I can’t buy it using PayPal. I emailed the author asking how can I pay using PayPal. To surprise me most, the author sent me a copy of the book with the reply email. I guess, he could feel my interests to read this book. I can’t be more happy.

I’ve just started reading it and yet to complete the first chapter. I am loving what I’m reading. I’m feeling indebted to Ruby seeing how far it goes with my written codes :-). I had no idea that, internally, it cares so much about my code and does so many things before returning me what I expect.

Ruby and MongoDB Web Development Beginner’s Guide Review

I remember the days when I’ve used MongoDB  in simple Ruby on Rails (RoR) project using Mongoid. It’s so simple to use MongoDB with RoR without knowing much about it. While using MongoDB, as a project requirement, I became more interested about it and decided to dig more. The moment I wanted to learn more about it, I found the book Ruby and MongoDB Web Development written by Gautam Rege. Thank goes to my colleague Rubayeet Islam, who suggested me this book. When I started reading it, I started feeling at home as I’ve already familiar with several Ruby/Rails/MongoDB concepts that I’ve learned during my works. However, here is my overall feelings about the book.

The first four chapters of the books talks solely about MongoDB. You will learn how to install it, run it, query it, use complex queries etc. and all of these using the default mongodb client.

Review on my Android based Chinese clone of IPad!

On November 2, 2010 I have ordered this item from eBay! I was skeptical whether I will get the item in hand or not because our postal service is still of medieval age! And the most shameful thing is that the dishonest custom and postal service officers even keep the items for themselves it attracts their attention. Moreover, last time sent me two books for reviews however these bloody custom officers asked BDT 2000 tax for these though the books were gift! My bad luck is that, being a student I could not afford that high tax/excise duty!

All such experiences made me thinking that I won’t get things in hand! However, on the last week of November, 2010 I received the items (I have also ordered a speed light for my DSLR). Most interesting thing is that two items came from different countries and order in two days gap. However, I received both at a time. Now, let me say something more about the APad!

Read/Write on Mac OSx partition from Ubuntu

After dual booting with Ubuntu and Mac OS, I could not write on Mac OS partition. However, I must have to find a way to do that as I will move certain things to ext3 partitions to be seamlessly usable by Ubuntu.

While reading online, somewhere I have read that I will need to disable journaling in Mac OS partition to mount it on Ubuntu with writing permission. I wanted to do the same but I saw the Enable/Disable Journaling button is not enabled in Disk Utility. So, after searching I found a command to do that from command line. It is simple.

# diskutil disableJournal /Volumes/Macintosh HD

That’s it. It disabled journaling on that partition. Later on Ubuntu I mounted the drive and I could write on it.

More Info:

Mounting the partition on Ubuntu

sudo mount -t hfsplus /dev/sda2 /media/mac
