NodeJS + CouchDB Concept in Action

2011-08-26T17:02:00.000-07:00

Here is the concept in action:
http://siddiq.no.de/dubai-gold-rates.html

This app is pure Javascript:
A complete Javascript stack is not only a reality, its fun.

1. Backend Server Language
Javascript running in NodeJS (http://nodejs.org) hosting on Joyent for free. See http://no.de

2. Database stored procedures Language
Javascript running in CouchDB (http://couchdb.apache.org/) hosting on IrisCouch for free. See http://www.iriscouch.com/service

3. Front-end GUI + Charts (No flash used i.e. HTML5 + CSS3)
HighCharts uses HTML5 + CSS3, so you don't have to use Flash. http://www.highcharts.com/

SOLVED /etc /sysconfig /modules /VirtualBox-OSE.modules

2011-08-09T11:00:00.001-07:00

I updated kernel and my VirtualBox-OSE stopped working. Asking me to run this command: /etc/sysconfig/modules/VirtualBox-OSE.modules

But this command would fail with following error.
$ sudo /etc/sysconfig/modules/VirtualBox-OSE.modules
ERROR: modinfo: could not find module vboxdrv
ERROR: modinfo: could not find module vboxnetflt
ERROR: modinfo: could not find module vboxnetadp

SOLUTION:
The easiet solution is to download stable package from the site, instead of resorting on yum repos:
http://www.virtualbox.org/wiki/Linux_Downloads

NOTE :
This happens becuase yum repos are not updated soon after the kernel is released. It usually takes hours and days depending on the packages.

Awesome NodeJS performance on a VM in Joyent cloud

2011-05-06T01:32:00.000-07:00

VM running on Joyent cloud has a very fast processor.

Having some fun, crunching a number on my machine vs a smart machine on joyent cloud.

Here is the code:

sys = require('sys');

var counter, d, d2;

// sync with clock
d = new Date();
do {
    d2 = new Date();
} while (d.getSeconds() === d2.getSeconds());

// run for a second
counter = 0;
d = new Date();
do {
    d2 = new Date();
    counter ++;
} while (d.getSeconds() === d2.getSeconds());

// the number that was crunched
sys.puts('counter = ' + counter);

My machine specs:
Intel core2 duo 1.6GHz * 2
2GB RAM

Joyent SmartMachine:
Vistual machine with some SPARC server machine as host
128MB RAM

gitk looks ugly: qgit vs gitg vs gitk

2011-01-18T00:31:00.000-08:00

A quick comparison between gitk vs gitg vs qgit and why gitk looks ugly?

	gitk	gitg	qgit
Version	1.5.6.5-3	0.0.6	2.3
GUI	Tcl/Tk	GTK	Qt
Looks	ugly	awesome	less awesome
Speed	fast as expected	very slow	very slow
Features:	search only	basic search only	more features then gitk and gitg

Acquiring packages:

sudo apt-get install gitk
sudo apt-get install gitg
sudo apt-get install qgit

gitk:

Nice visualization but a scary gui. Look at the buttons you cant tell they are pressed or unpressed. The gui problem is also because its based on tk/tcl which doesn't honor the GTK theme.

After showing the initial view, it keeps running a background process to scan local uncommitted changes which are finished in 45 seconds for my project. Which is a cool feature.

gitg:

Provide the awesomeness of gui that is expected in gnome. i.e. proper GTK theme settings.

The problem is that its slow. It says "Loaded 1893 revisions in 32 seconds.". Even if I turn off the options to show stash/staged/unstaged changes I still wait for 32 seconds to load the history on my project.

qgit:

Loads 1893 revisions and directory changes in 61 seconds. But if you turn off 'check working directory changes' then it becomes very fast and loads in less then 5 seconds.

Provides more features then gitk and gitg.

A little less awesome then gitg bot a lot more awesome then gitk.

Recursively delete .svn directories in Linux

2010-08-22T06:54:00.000-07:00

See the .svn folders:

$ find . -type d -name .svn
./.svn
./js/.svn
./tests/.svn
./tests/js/.svn
./assets/.svn 

Delete the .svn folders (pass the output to rm -rf):

$ rm -rf `find . -type d -name .svn`

You may want to create a shell script to automate...

Facebook Credits Integration for Developers

2010-02-07T01:21:00.000-08:00

Just like many other developers I was interested in Facebook Credits testing program. Still waiting for their beta launch.

For signup for beta testing program you may want to sign in here:

Other options for virtual currencies

Direct credit card transactions
PayPal
Google CheckOut
Amazon Payments
Mobile payments (Zong, PayMo, Mobill Cash, etc)
Affiliate providers (SuperRewards, OfferPal)
Third party virtual currencies (e.g., SpareChange, Social Gold)

Facebook Credits Pros and Cons
As not much specifications annouced from facebook so we can only speculate with limited details and what industry specialists say about it.
Pros
- Simple interface for customers. Less clicks.
- More trust
Cons
- Platform not much tested
- Can't completely replace other Virtual Currency providers. So developers have to maintain parallel systems.

Some Apps that are currently using Facebook credits:

Zoo World — Zoo World
Crowdstar — Happy Aquarium (7.3 million DAU), Happy Pets (2.9 million DAU), Happy Island (just launched)
Playfish — Restaurant City (4.2 million DAU)
HitGrab — MouseHunt (173,000 DAU)
Zynga — Pirates: Rule the Caribbean! (159,200 DAU)
Playdom – (Lil) Green Patch (79,228 DAU) and TikiFarm (just launched)
GPI – Robin Hood (11,104 DAU)
Alamofire – PackRat (8,442 DAU) – although I couldn’t identify the integration point

I was surprised to see FarmVille not in the list.

[Humor] Do you have any other browser? Mozzarella? Chrome?

2009-07-07T00:34:00.001-07:00

"Do you have any other browser? 'Mozzarella'? Chrome?" asked the tech support agent of PTCL DSL. My first impression of PTCL tech support fallen down 100 ft underground.

Funny thing happened. The other day, the installation guy had installed the modem but didn't get the internet working. He didn't even know what username and password should he put in. He tried a couple of them (from his hand written notes) but none of them worked. Lights went down (load shedding) so he left things unfinished.

Now the funny thing is he reported his manager that modem installation was successful. Since that is what the CRM is telling the tech support agents.

There are a lot of things I can do here. But I infer that PTCL has a poor technical support and pitifully inferior and miserable low profile work style.

Ok here is my feedback to PTCL tech support:
PTCL DSL =

What's Wateen doing? 1mbps = 1620 PKR???

2009-06-20T07:28:00.000-07:00

I just happened to learn their three new packages with no download limit:
1mbps -> PKR 1620
512kbps -> PKR 1520
256kbps -> PKR 1420

Now how on earth does this compare with PTCL's eVDO technology and the package they offer ??? i.e.
3mbps -> PKR 2000
Plus, EVO terminal is a USB device so its portable and it does not require external power other then USB socket (i.e. no WAPDA).

Secondly, whats with difference of RS 100 with every package???

PTCL eVDO technology

Wateen Wimax Service

They don't have details of new packages on the website by the time I was writing this blog. So I called their helpline 111365111.

FileZilla much better then gFTP and others

2008-11-20T05:25:00.000-08:00

FileZilla is the solid, feature-rich and practical ftp client that one should be looking for all needs.

I had been using Kasablanca, gFTP, Nautilus and Konquoror. But was dissatisfied with the goodness we expect in Liunx. I wondered why I wasn't using FileZilla before. Maybe because FileZilla is not reviewed enough in blogs?

Install on Fedora:
yum install filezilla

Ubuntu:
sudo apt-get install filezilla

VirtualBox vs Vmware

2008-11-15T23:11:00.000-08:00

Here's my first go with the VirtualBox. (For a detailed review I found Jason Perlow's article very useful Virtualization smackdown: Sun xVM VirtualBox 1.6 vs. VMWare Server 2.0 Beta 2)

I had been enjoying a fedora laptop. (Yes, its not Ubuntu. I will write in another blog about my reason for dislikeness)
Then I gave a shot to redmond os in my virtual space. Both VMware and Vbox went smooth and great.

Here are the screen shots:

Fig: VirtualBox's "seamless mode" is the feature I love. Here is a screen shot with it. Notice the windows taskbar aligned with top and kde's taskbar aligned with bottom.

The desktop background is the default fedora's and then IE window running in the foreground.

In the last screen shot if you look closely, an IE window (right) is running in the guest OS and the Firefox window (left) is running in the host OS. Thats the beauty of the Seamless mode.

Although VMware has been the industry leader and default choice for personal and enterprise level virtualization requirements for many years. But now Vbox is equally solid, feature rich and no less.

In short, I personally feel that over the time VirtualBox will carve a broader market share in virtualization. It has more support of host systems.

Here is Jon Galloway's blog who got the idea from Wyatt Preul's post on deleting svn directories.
http://weblogs.asp.net/jgalloway/archive/2007/02/24/shell-command-remove-svn-folders.aspx

Jon Galloway made the following registry entries that will make your life really easy.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\DeleteSVN] @="Delete SVN Folders"

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\DeleteSVN\command] @="cmd.exe /c \"TITLE Removing SVN Folders in %1 && COLOR 9A && FOR /r "%1" %%f IN (.svn) DO RD /s /q "%%f" ""

Here is what you get:

All you need to do is to make text file with a .reg extension and add these entries.
Then run the .reg file.

Geek Idea, how to make a wind powered truck

2007-09-28T19:56:00.000-07:00

I just made a wind powered truck today so here is the recipe.

You need 3 toys to make this gadget run.
1. a truck
2. a propeller (for this we will use a r/c helicopter)
3. a playing doh to join them

Total time: 10 minutes

a truck
a doh
a r/c helicopter

These are all cheap items you can get them from any toy store easily under 10 dinar for all. (or check with your kid he may already have some or all of them)

Now arrange the items like this, so when the propeller pushes the air, the truck can move. Use the doh to join the wheels of the helicopter with the truck.

Now everything is ready. Make sure the surface is plain so that truck has minimum surface resistance and can move easily. Use the remote control of the helicopter to run the fan/propeller and enjoy. Here are a few video clips.

Please do write me a comment if you make something like this or something in reply of this.

Are all parents interested in r/c toys?
