How to resize a VirtualBox VDI file on Mac OS

Recently, I had to do this as 10GB was not sufficient for Centos6.7 VM. I would just like to mention simple steps for how to do it.

  1. Shutdown VM and quit from VirtualBox.
  2. Open the terminal and go to the below path (default location). From here you can run the command to resize the VDI file.
    Nils-Mac:MacOS nilnandan$ pwd
    Nils-Mac:MacOS nilnandan$ 
  3. Start another terminal with command + T and find the directory where actually the VDI file stored. Default location would be ,
    Nils-Mac:centos67-mysql nilnandan$ pwd
    /Users/nilnandan/VirtualBox VMs/centos67-mysql
    Nils-Mac:centos67-mysql nilnandan$ ls -alh
    total 21925920

"Making bank" at MySQL (AB/INC)

Just because this topic came up more than once at MySQL Connect...

Apparently, some alumni have been awarded bonuses for certain pieces of work during their time at MySQL and I guess that there was an expectation from some that the same applied to the work I did. Now, I don't want anyone to get the impression that I am experiencing "sour grapes" over the past - I actually enjoyed much of my time

I want to contribute,

Over at David Stoke's Open Source DBA blog, the following was posted: My reply: Allow me to contribute code with a BSD (3-clause) license without having to sign anything new and then we can talk. Don’t tell me that it can’t be done: Oracle already has some code of mine in another product which was

How does MySQL hide the command line password in ps?

I saw this question asked today, and thought I’d write a quick post about it.
Giving passwords on the command line isn’t necessarily a fantastic idea – but you can sort of see where they’re coming from. Configuration files and environment variables are better, but just slightly. Security is a night mare!

But if you do decide to write an application which takes a password (or any other sensitive information) on the command line, you can prevent other users on the system from easily seeing it like this:

#include <stdio.h>
#include <unistd.h>
#include <string.h>
#include <sys/types.h>

int main(int argc, char *argv[]){

int i = 0;
pid_t mypid = getpid();
if (argc == 1)
return 1;
printf("argc = %d and arguments are:\n", argc);
for (i ; i < argc ; i++)
printf("%d = %s\n" ,i, argv[i]);

Fake O'Reilly Covers

Here are some of the fake O'Reilly book covers I mentioned in a prior post.  These have been optimized for use as black & white Kindle screensaver wallpaper images.  If you haven't done so already, you can install a Kindle screensaver hack with a couple of downloads. 

Update: I've embedded a slideshow from PicasaWeb, but it requires Flash.  If you don't see it you can click on the links below to go directly to PicasaWeb.

Help Bring Zork and the FyrevM to Android, Kindle et al

David Cornelson of TextFyre has embarked on an ambitious plan to create a new open source virtual machine, FyreVM.  This new VM will run Interactive Fiction games (e.g. Zork and newer works written in Inform) on a dozen different mobile platforms such as Android, WinPhone 7, Kindle, iPhone, iPad, Blackberry.  The goal of FireVM is to take advantage of specific user interface capabilities on each platform, whether it's the touch screen of Android tablets or the 5 way button on the Kindle.

To help with this project, TextFyre has started  a fundraising effort on Kickstarter with a goal of …

iPhone 4: First Impressions

I managed to get an "early upgrade" of my iPhone 3GS to the iPhone 4 despite AT&T's best efforts.  I've had a couple of days using the new iOS 4 operating system on my 3GS and a couple of hours with the iPhone 4.  So here are a few highlights of the initial hands-on experience with more updates on the weekend.

Updated with additional information, video & photos.

Low-res video (VGA resolution):

Here's a gallery of additional photos from the iPhone 4:

Upgrade Process

Other than AT&T's longstanding inability to deal with demand, the upgrade process is pretty simple.   I chased the UPS driver home to get my iPhone today and just plugged into the USB cable to restore my last iPhone 3GS backup.  That took about 20 minutes. …

Dennis On the Road to Recovery

(Click on the image to enlarge)

Dennis Wolf, former MySQL CFO, has been undergoing Plasmapheresis treatment in the last week and despite a mild setback due to an infection, he will be checking out of the hospital today to continue rehab as an outpatient.  Dennis reports that he has increased mobility in his leg and that the test for Devic's Disease and Multiple Sclerosis has come back negative.  So there's a bit of a mystery as to what has caused this NMO flareup, but …

Dennis Wolf Undergoing Treatment for Devic's Disease


Dennis Wolf, former CFO of MySQL, is in the hospital undergoing treatment for neuromyelitis optica (NMO) also known as Devic's Disease.  This is a spinal cord inflammation with similarities to Multiple Sclerosis.  Dennis is a very special guy to get such a rare disease. He's also a tough son-of-a-gun, so I have no doubt that he will put this behind him with a full recovery just as he did 18 years ago.  But it will take some time, attention and help from many people. 

He has started  …
