iKeyword – Free 1.0.1, iKeyword 1.0.2 and a busy week

by

iKeyword – Free, free iPhone App was released on Monday to help you whether it’s worthwhile to purchase the paid iPhone App iKeyword. iKeyword – Free is a huge success, if you haven’t already tried it you should head over to the App Store and download. Available on the App Store

On Thursday (29th July), an update to iKeyword was released enabling users fetch unlimited number of related keywords based on user feedback upping the version to 1.0.2 from 1.0.1 . If the number of related keywords returned was an issue that prevented you from using iKeyword; download to iKeyword 1.0.2 now on the iPhone App Store.

Whole of this week I have been working on an uber cool iPad application which will hopefully be released in August, it’s a biggie. Stay subscribed or follow me on Twitter to be the first to hear when it’s released.

Btw, system administrator appreciation day falls tomorrow; do not forget to throw a party for your SysAdmin, get him/her a gift or just say thanks 🙂

How to redeem iTunes App store coupons

by

When distributing iKeyword coupons everyone was having issues with figuring out where to enter the coupon. Apple did a good job to make sure unsuspecting users will end up buying the app instead of redeeming the coupon because there is no way to use the coupon from the iTunes on the iPhone and even with iTune for Mac or Windows you couldn’t redeem the coupon from the App details page, clever of you Apple.

For everyone’s benefit;

  1. Power up your PC or Mac
  2. Open iTunes
  3. Goto iTunes store home (Click the home icon once you get to iTunes store)
  4. Click “Redeem” under “Quick links” (highlighted in the screenshot above)
  5. Key in the redeem code and click the Redeem button

Enjoy your app free app 🙂

First iPhone app released

by

Available on the App Store iTunes Connect - iKeyword Last Wednesday first iPhone app was released under my account, iKeyword. iKeyword allows you to search for related keywords on your iPhone or iPod Touch. I use Google AdWords keyword suggestion API to discover/generate keywords. It was a fun project. I also need to give a shout out to Oliver Tani for giving me feedback on what Online Marketers really want.

To much to my surprise Apple’s approval process only took 7 days (5 working days), thank you Apple for speedy approval 🙂 . See the screenshot of iTunes Connect bellow.

How to use Huawei E1550 on Snow Leopard (Mac OS X 10.6)

by

I recently upgraded to Snow Leopard and wanted to download iPhone SDK, since Dialog GSM has really cheap bandwidth, I got a 2 hours on my Kit Broadband package. I’m using a Huawei E1550 but unfortunately the Mobile partner that came with the dongle didn’t work on Snow Leopard. With a bit of Googling I came across Huwaei Device site and downloaded Dashboard for Mac OS X 10.6 and unzipped it and then unzipped MAC-V100R001B301D11SP00C03.zip (only zip file in the downloaded zip file). The ISO file needs to be mounted with Disk Utility and not the Disk Image mounter.

Then the familiar Mobile partner will open up, and follow the instructions on the screen.

Hope this helped someone in a similar situation 🙂

Interesting domains going on sale

by

While building R2G Tools I discovered some interesting and rare domains, I jumped at the opportunity and registered them. Now they are going on sale to raise funds to make R2G Tools better. Here are the domains.

direct-marketing.biz
Page rank 3 domain with a generic term. Rare opportunity no direct marketing firm should let go.

iaews.biz and iaews.us
Pair of page rank 7 domains. Not sure what iaews stands for but I’m sure what ever you host will make to the top of the Google index fast. Great SEO value.

meridianhealthcare.us
Page rank 5 domain. Great for a US based health care firm. If you are lucky New Jersey based Meridian Health will definitely be interested in this domain. Great opportunity for an experienced domainer.

Send me your offers, these domains are going fast as I need the cash fast to improve R2G Tools and I’m not very good at hard selling 🙂

Building R2G Tools

by

I started out building a tool to discover recently dropped domains and in the process domains search engine with a twist. You can check it out at R2G Tools . This was a extremely challenging project, with more than 120 million domains in the world and extremely tight budget. I finally pulled it off last week end. You would be surprised that whois.r2g.in is running off 3 commodity servers (mainly for redundancy, I could have squeezed it into 1 with only slight performance hit).

What’s behind

Database; MongoDB is the main database backend, with MySQL used to hold non domain records. MongoDB was chosen because of it’s ability to handle large amount of objects, schemaless and ability to index keys. Thanks to MongoDB I can search, count and even insert and update records in few seconds (most operations are few milliseconds).

Web application framework; whois.r2g.in is completely built with CodeIgniter. It’s my framework of choice. I like it’s clean and lean architecture.

Servers; I’m running Lighty behind Varnish HTTP accelerator. I also use eaccelerator to optimize PHP code. I also have a memcached instance on the web server to cache data from MySQL. Goal is to speed up whois.r2g.in as much as possible. There are 2 MongoDB instances sharing the load which the application connects. Everything is running off 3 Athlon X2 servers, 2 running MongoDB instances and one running the application.

Why use both MongoDB and MySQL?

That’s because I didn’t want to put all my eggs in one basket. Any data that doesn’t change much like WHOIS servers put into a MySQL table. Information such at WHOIS data were stored in a MongoDB collection.

What I gained?

Lot of experience about data mining, storing and analyzing. I learned a lot about how to optimize data mining, I managed to bring down the time it takes to analyze all the domains for drops to few hours from few days by just pre sorting the zone files. I also gained few rare domains and high page rank domains. I have become a domainer thanks to the project 😀

Please head over to R2G Tools and give it a try,  you might discover a great domain while you are there and make a huge profit. Do not forget to send me some feed back 🙂

How to find out the iPhone/iPod Touch device ID without Xcode?

by

  1. Connect the iPhone or iPod Touch to your Mac or PC
