Process is like a bicycle

Process is like a bicycle. You have to use it to get to the destination. But what happens in most cases is to go to the destination by hook or crook and then go back to origin and carry the bicycle on your head to prove that bicycle was used!

Hurray!. New Broadband Operator

May 1st, 2008 by koolb | 3 Comments | Filed in Uncategorized

Sri Lanka Electroteks to start broadband, voice in May
Electroteks chief B A C Abeywardene says the service will use CDMA
(code division multiple access) based technology to provide up to 1Mbps
speeds and voice calls priced around 1.50 rupees a minute, which is
about half the current tariffs.

ADSL (asymmetrical digital subscriber line) services are now priced at
just under 20 dollars a month, but Electroteks says it will give higher
download speeds.

- LBO

According to the above LBO news item Electroteks will launch its Broadband network in this may. They promised to provide better service using CDMA technology for the same price.

Following are some of my thoughts which need be considered by the new operator when packaging and costing their products.

Better QOS
Most of the European operators publish their sharing ratio of the bandwidth with their packages(e.g 1:50 or 1:10). This way the customer knows what they are paying for. But in Sri Lanka operators promised to give the sun and the moon but in reality the connections are very slow and you don’t know the sharing ratio of the service you are getting.

Opportunity to select packages based on the needs
Currently SLT and Dialog only offers DSL connections. In SLT ADSL you don’t know your sharing ratio and you don’t have the option to go for a better package if you want a good service by paying more(Specially for corporate customers). End of the day you are in the same bandwidth pools(512Mbpspool or 2Mbps pool) what ever your need is.
Same time Dailog broadband offers the maximum of 4Mbps links advertising no quotas. But they shamelessly limit your bandwidth using a Fair Usage Policy. Quota for a 4Mbps packages is 16GB. They even offer you an IP even to run your own Mail or Web servers. If you divide the quota by 20days, you will get roughly 800MB per day. Whats the purpose of having a 4Mbps link with 800MB quota per day?
The above operator are very unreasonable as they don’t offer alternative packages to customers who wants more. Therefore everybody needs to stick to the same package what ever their need is.

Lower broadband equipment and setup cost
Dialog setup cost is Rs. 5000 which is very unreasonable.

eBooster – boost your XP, Sinhala interface

April 26th, 2008 by koolb | 2 Comments | Filed in Enhancement, Software, Windows

eBoostr brings the benefits of Windows Vista’s ReadyBoost to XP. eBoostr could be perfect for XP users who want a little extra memory but don’t want to install RAM, or for laptop users who have no way to increase memory. Following is a comment from the lifehacker post which proves its performance

Ok guys, I just tested my Lenovo T61 laptop with the eBoostr

w/Cruzer SanDisk U3 2m memory stick.

For my full system specs, see this:
[screencast.com]

Here’s the benchmark WITHOUT eBoostr:
[screencast.com]

Here’s the benchmark WITH eBoostr:
[screencast.com]

I ran both right after system reboot with no major apps open other than my usual (light) startup list (anti-virus, and a very short list of must-load startups).

As you can see, there is some improvement but it doesn’t seem to be major…

what do you think, should I keep it?

Special thing I noticed was Sinhala was available in the language selection box. This is the first software from a international vendor, which I have seen Sinhala in the language selection. This is how it looked when I changed the language to Sinhala ( I was so excited and even took this screenshot even before I restart the PC :-) )

Is it really required to show the User Name and Password in ASP.NET Error Page?

February 3rd, 2008 by koolb | No Comments | Filed in .NET, ASP.NET, Internet, Programming, Software Development, Web Development

I got the following ASP.NET error when I was browsing a local web site. The error is due to ASP.NET cannot authenticate using the User Name and password in the impersonate tag. Ther real issue is not the windows authentication problem. Because the reason for the error could be the domain server is down or the administrator has used an incorrect user name and password in the web.config.

But is it sill good to show the User Name and Password in the error message? You can argue that the developer has switched on CUSTOM ERROR MESSAGES and he has forgotten to switch it off at the time of deployment. But still is it really required to show the whole user name and password in the error? If the necessary ports are not secured, someone can easily login to the server and mess up the server very easily. (In this case only the port 80 and 21 is open and this user won’t have permission for FTP.)

Sri Lanka – Broadband QOS (Quality of Service)

January 29th, 2008 by koolb | 1 Comment | Filed in Broadband, Internet, Sri Lanka, Web

I have ADSL connection and Dialog WiMax connection at our work place. ADSL should have speed of 2Mbps, but it has around 800Kbps of real speed at off peak hours and on peak hours it goes down to speeds closer to dialup connection (around 100Kpbs). Dialog WiMax still maintains a good QOS. But still at peak hours it is 800Kbps for a 4Mbps connection and on off-peak hours it is around 1500Kbps. So I had the question whether the regulator of ISPs in Sri Lanka has rules on QOS for Broadband when they issue the operator license to the ISPs. But I couldn’t find any on the Service or Bandwidth QOC for internet or Broadband in the TRC web site. They only have some QOC Indicators to monitor Telephony services.

I found the following line below the tariffs when I was referring to Airtel India web site.
“* Speed indicated are only speed upto our ISP Node and are given on best effort bases as per TRAI guideline on Quality of Service for Broadband Service”
TARI is the Indian regulator. I checked their website on the guidelines they practice in India for Broadband services. I found “TRAI issues Regulations on Quality of Service Standards for Broadband Service” document which explained various indicators of QOS to protect broadband consumers.

I couldn’t figure out why the DSL and other broadband services license and tariffs are defined unconditionally in Sri Lanka. As I can understand from the TRC web site, any ISP can market a product indicating a huge bandwidth offering. But the QOS of the Network bandwidth they should offer is not enforced by the regulator. Basically they can share the network bandwidth with any number of customer since there is no minimum bandwidth QOS enforced by the regulator.

So that’s how it goes… we will hope someday TRC – Sri Lanka will take necessary actions to protect Broadband consumers.
