Apple has finally announced the long awaited SDK for iPhone. Looking at the amazing games and enterprise softwares that third party were able to develop in just two weeks I’m convinced that iPhone will be an excellent gaming machine as well as a hit enterprise handheld device. The next release of iPhone firmware version 2.0 due to be released in June will have native Exchange support, Cisco IPSec VPN, remote wipe capabilities, WPA2, and many more…

Here’s a nice iPhone SDK comparison chart by engadget.

Another good news for iPhone users in UK is that BBC has launched iPlayer video on demand service for the iPhone and iPod touch. I just watched the BBC News on my iPhone and it’s just awesome!

What Do Computers tell us about God?: A reflection of a Computer Scientist…

GFI LANguard Network Security Scanner is a very easy to use yet powerful commercial Network vulnerability scanning, patch management and auditing tool. If you have a small network with few computers then it’s easy to keep track of the softwares installed and do the patching manually, but for larger networks it would be a nightmare to do everything manually. This is where tools like GFI LANguard NSS come in to help network/system admins. GFI LANguard NSS makes use of the vulnerability check databases based on OVAL and SANS Top 20, providing over 15,000 vulnerability assessments when your network is scanned. It is one of the best commercial network security scanner and patch management tool available.

I’ve installed and tested it in my WinXP SP2 running on my MacBook Pro Vmware Fusion, and this is what I found.

I don’t know about other ISPs in UK but I can tell you that Orange is the worst I’ve encountered. I’ve been without the internet at home for 23 days. The broadband stopped working from 23rd of December 2007 (for unknown reasons) until yesterday, but I still don’t know what was the problem. I’ve made more than 10 calls to it’s customer support and they’re clueless about the cause of outage. The call gets redirected to it’s support center in India and the support staff absolutely have no idea about the problem. Every time you call them they’ll tell the same thing: “The case has been escalated and will be solved within 5 working days” and they’ll ask you to follow the Livebox (wireless router) reset procedure. It’s probably one of the worst customer service… no followups, no idea about the problem and the service goes on and off like magic. They sign you up for a 18 to 24 month contract and once you’re hooked who cares…

I’ll probably never join Orange again!

Thanks to the iPhone, I was able to keep up with the personal emails and relatively decent web browsing.

It’s been interesting times for me here in London. Life has taken many turns and I’m enjoying the Journey. Just wanted to let you all know that I’ve joined ShipServ as a System Manager and will be looking after their network, infrastructure and Security.

I’m really honored and delighted to accept the new challenge and start this new phase of my career.

After upgrading to Leopard I’m experiencing random keyboard freezes in my MacBook Pro. It’s very annoying! After a quick Google I found many people having the same problem.

Leopard is sleek and polished with some great new features, but it’s not as stable as Tiger. Besides the keyboard issue, it fails to shutdown or reboot time to time. The finder hangs and need to shutdown pressing the power button.

Hopefully Apple will acknowledge and address these issues soon.

Update: Apple finally released this Software Update to fix the freezing keyboards.

If you’re running a web site and have come to a point where a single web server cannot handle the traffic, then it’s time to get multiple web servers and share the loading. To do that you’ll need a load balancer which distributes the web traffic among multiple web servers.

Basically you’ve two choice — go for the hardware solutions (expensive with many nice features) or software solutions (possibly free but with limited features). If you want a free and open source solution then Pound is the choice.

Pound is a Free Open Source reverse-proxy, load balancer, SSL wrapper, http/https sanitizer, fail over server and a request redirector:

1. a reverse-proxy: it passes requests from client browsers to one or more back-end servers.
2. a load balancer: it will distribute the requests from the client browsers among several back-end servers, while keeping session information.
3. an SSL wrapper: Pound will decrypt HTTPS requests from client browsers and pass them as plain HTTP to the back-end servers.
4. an HTTP/HTTPS sanitizer: Pound will verify requests for correctness and accept only well-formed ones.
5. a fail over-server: should a back-end server fail, Pound will take note of the fact and stop passing requests to it until it recovers.
6. a request redirector: requests may be distributed among servers according to the requested URL.

Pound is built with security in mind, it can run as setuid/setgid and/or in a chroot jail. It’s a very small, robust and efficient program.

It’s very easy to install and configure.

Finally got my hands on the iPhone today!

We’ve all watched/read so much about the iphone and it’s coolness that expectations were quite high. And I’ve to say that I was not disappointed. It’s really cool, slim and gorgeous. Most of the things work perfect. I think the keyboard is not an issue.

iPhone was launched today at 6:02pm in UK and could be bought in Apple Stores, O2 stores or Carphone Warehouse stores. You’ll have to sign 18 months contract with O2, which is the exclusive carrier in UK.

There’s one Carphone Warehouse store few blocks away from my house, so I went to check out at 6pm. Surprisingly there were just around 20 people queuing up. The store opened at 6:02 and everybody was let in. But there was a problem with carphone warehouse’s payment system. I’m not sure if the system was flooded by iPhone transaction or other technical issues. Anyway, it took more than half an hour just for the payment authorization. I was the first one to walk out of that store with the iPhone. They authorized the payment manually, bypassing the chip and pin (security system in UK’s bank cards).

Activating iPhone with iTunes was a smooth and painless process. I am currently using Vodafone, and got the PAC code from them few days ago. PAC code is a special code to transfer your mobile number from one provider to another. My existing mobile number will be automatically transferred to my iPhone after 7 days, until then O2 has assigned me a temporary number. That was clever.

Played with most of its features, made several calls (quality is quite good) and tested the visual voice mail (which should be very useful). Synced my address book, music, podcasts, some photos and videos. iPod is excellent. Gmail and IMAP mails are easy to configure and work without any problem. Photos are very cool, flipping them, zooming in/out, resizing was fun. Google Maps will be very useful for me finding places in London, it loads pretty fast even on EDGE Network.

Only problems are the Wi-Fi connection and YouTube. I use a 128bit WEP HEX Key at home and couldn’t establish connection with my Access Point. Quick Google gave me this (seems to be a known issue) but using $ in front doesn’t solve the problem for me. For the YouTube Videos It says that it requires an EDGE or Wi-Fi connection.

I think these two problems can be fixed easily.

I’m just having a good time playing with it. You’ve to hold it and use it to really appreciate it. It was a nice Deepawali gift for myself!

I’ve just upgraded my MacBook Pro to Leopard. I expected it to be very smooth and painless as many other users have reported, but unfortunately I encountered some problem. I had to spend around extra 4 hours, and was worried about losing my data all the way until the upgrade was complete.

So, this is what happened. I inserted my Leopard DVD and clicked on Install Mac OS X, then my MBP restarted. I chose the option to Upgrade (it actually detected and told me that I wanted to upgrade). It took around 2 hours to complete and asked for a final restart. That was supposed to be the end of upgrade, but after the final restart my MBP was stuck on white screen with apple logo. I waited for half an hour, then it became obvious that nothing was happening, so I pushed the power button and re-started again, which led to the same white screen. At this point I was quite worried about my data. I had done my last backup 2 months ago. Actually I should have backed up before starting the upgrade, but I thought since everyone is doing it smoothly why would I have a problem? Also I was too excited to experience the Leopard that I didn’t want to spend time backing up, and neglected the risk of losing 2 months data.

Stuck in the white screen forever

When I read Mahabir Pun’s story about how he brought the wireless technology to a remote mountainous village of Nepal called Nangi, I was amazed by his determination! What an inspirational story of a man with a noble cause. It really gave me goose bumps, I just thought what a difference one committed individual can make to a society. With his determination, hard-work, and dream, he changed the lives of all the people of Nangi village for better. What a meaningful way to use the technology and what a wonderful way to live this life. I sincerely wish I could do something like that. I’ve written to Mr Pun and hopefully I could be helpful to his project in someways.
