FogBugz based on Event Bsed Scheduling
Most of the systems which we currently see (for example Jira, Bug tracker) are based on the fact that they are good at reporting, maintaining and tracking (somewhat) bugs and tasks. That's it. The role of a bug/task tracker system usually ends there. (if you been making more use of a bug tracking/task management system, drop me an email).
There is where FogBugz is different from rest of the systems. Probably the most interesting part of FogBugz is Evidence-Based Scheduling, which uses a statistical technique called bootstrapping (a variation on Monte Carlo) to determine the probability that you'll ship on any given date. In short, this is how it works. You estimate features as usual. But then, instead of adding up all the developers estimates—instead of taking them on faith—FogBugz does a Monte Carlo simulation looking at what speeds developers worked at in the past, vis-à-vis their estimates.
In Joel's words:
Using that same distribution of probabilities that we had in the past and if we run a simulation of 60 futures each of which will occur with equal probability, what we get, instead of a date, is a probability distribution curve that shows the probability that the product will ship on such-and-such a date.
Now thats what i call an awesome sfotware tool, which really stands out. Well how reliable and accurate FogBugz is, is another question.
I think i got to try it to find out!!!

Orcas
Then there are good C# features such as automatic property generation. So from now we do not need to write both private memebers and thier public properties. The compiler can automatically generate this for you!!!!!
Another feature which i ahvent tried much but read about is the object and collection initializers. Though i felt that isn't an Object Initializer already present in the language in the form of a constructor? I dont know yet, will have to dig deep to find out whats going on inside.

Credit Crunch - Will this lead to recession?
As financial times stated: “When the patient is in seizure and the extremities are starting to turn blue it is not the time to worry about the patient’s longer-term dietary plans or about undesirable side-effects of the current treatment. Yet I fear this is what central banks will do. The next set of steps had better be convincing and decisive, otherwise a much wider financial implosion and economic recession will become very likely.”
How will it affect the jobs in the city? Will we see a slowdown? Lets wait and watch

Artificail Intelligence - Machines taking over?
Singularity Institute Research Fellow Eliezer Yudkowsky explained over the weekend at the Singularity Summit why many believe that machines will eventually be smarter than their makers. The stunning progress in packing more computation power onto silicon chips, married with software designers’ increasing ability to take advantage of this power, virtually guarantees that machines are progressing faster than humans are. One day, machines will start building themselves, he predicted. And at that point, humans will certainly no longer be the smartest creatures in the room.
All that conference goers could agree on is that life with machines won't be the same. And even if the machines that take over from the geeks are friendly, these new masters of the universe may not serve pinot noir.

Artificial Intelligence - Where are we heading to?
I had been reading quite a lot on the Singularity Institute for Artificial Intelligence recently. The singularity institue exists to confront the new world of Artificial Intelligence, both the opportunity and the risk. I have been interested in this field since 2003, when i took a module on AI in my Computer Science degree and thus have my own views to share.
Do you think the machines can take over mankind someday? - Well currently i cant imagine something like that. However i can imagine computers taking over most of our jobs. People worry about competing for jobs with people from Mexico or from China, but what about competing with computers for jobs? People will be friends with robots who tend to understand them better than other humans!!! It will be robots who will make decisions as to when are we supposed to sleep, when are we supposed to eat and what are we supposed to like. Now that seems scary right. I think in 20 -25 years time we might also have the first Human-Robot relationship(partners/marriage). In short, robots will be good enough to replace humans for almost everything.
Robots are already to the level of rather dumb/stupid pets. Given moore's law, they will be to the level of smart pets within three to five years... That much is just simple exploitation of systems that have already been developed... This is such deep stuff, and there is so much of it that it will really take a human+ intelligence to fully use the data that we have now, much less the data that we will generate before we are able to create that human+ intelligence.

Increase in spam in gmail
I used to get maximum of 3 to 4 spam mails in my spam folder in a week. However nowadays i receive 15-20 spam emails everyday. I dont know what is the reason behind this sudden increase or if others are also facing this situation recently. I tried searching on the internet but no related events have been reported by anybody.
One possible reason could be the fact that i registered on facebook around the same time and then suddenly i noticed the increase in spam. Is it something related to facebook? Are spammers getting hold of my email address from facebook? I wont be surprised actually as i have already started receiving job adverts/mails from agencies through facebook!!!
Let me know if anybody else faces the same situation.

Tiger Beer Singapore Chilli Crab Festival - Bricklane
I tried the Singapore's unofficial national dish (crabs!!! - you would have guessed by now), as well as other regional specialities such as Hainanese chicken rice, char kway teow and laksa.
You could even get henna tattoos there, watch Chinese dragon dancing and browse market stalls at this event organised by the Singapore Tourism Board.
Morveover walking around bricklane made me feel that it was quite similar to Camden Market. There were artists, musicians and lots of junk stuff being sold and bought. It was a nice expereince to see another aspect of life and ponder over it.
Still thinking about it actually.....

Sharapova's US Open wardrobe is inspired by New York's skyline
The dress is a sleek garment made of a breathable wicking jersey and constructed with a no-sew technique with seams bonded with heat and silicone instead of thread.
There are more than 600 Swarovski crystals incorporated into the design, adding a little flash to the outfit, but Sharapova said it's simple and classy, which suits her taste. "I don't like things with too much pattern ... things that are tacky.''
There also are three crystal buttons down the back, creating a keyhole effect.
No thats a quality dress i reckon. By the way she is through to the third round as well.

Behave# and NSpec - Behaviour Driven Development
Behave# is a framework for defining and executing application requirement goals. These characterizations are modeled after the Behavioral Driven Design (BDD) terms Story, Scenario, Given, When, Then.
Behaviour Driven Development, or BDD, represents the evolution of current coding practices with respect to Test Driven Development (TDD).
One of the good points of behave# is that that if you want to specify Exceptions as part of your story, this forces you to move away from [ExpectedException]. Which is a Good Thing anyway.
It is quite verbose, although the verbose-ness is one of the qualities that could make it attractive to product owners or PMs. The code is really to express acceptance tests rather than developer-focused 'unit' tests. (Have a look of Behave# code example on casper's blog)
I think i am going to try a real world example and see how it goes or to put it more appropriately to see if it grows on me and how comfortable i feel.

Debugging Microsoft .NET 2.0 Applications Book
On the first of page of first chapter i came across a few lines which really made me think how appropriate and improtant this book is for a progammer.
Quoting form the book Debugging Microsoft .NET 2.0 Applications:
"Debugging is also a part of software development that's famous for causing you to pull all-nighters. I'hv yet to run into an engineer who has called his or her partner to say, Honey, I can't come home because we're having so much fun doing our UML daigrams that we want to pull an all-nighter! However, I'hv run into plenty of engineers who have called their partner with the lament, Honey, I can't come home because we've run inot a whopper of a bug"
Well, I am sure any programmer (I mean a real programmer) would agree with this. Let me know what you all think
Google's gPhone
However, the on again, off again offering to the mobile world by the search giant is reaching fanatical levels of hype and thanks to a recent news story by Rediff News in India, the hype is only getting worse. The story published by Rediff said that the gPhone is two weeks away from launch!!!! Now that is some serious speculation. Sources close to the development said a simultaneous launch across the US and Europe and India is expected, and announcements would be sent to media firms in India and other parts of the world in a week.
Well but all this is still simply a rumor, but a good one nevertheless. Lets wait and watch if google makes an official announcement. If they come out with a gPhone by any chance i am definitely going to get my hands on it asap, as i just love the way they make software.
Opps...aren't we talknig about hardware too over here!!!

.NET Stock Trader Application
I am working as a Technology Consultant in capital markets domain and have noticed that microsoft technologies are still not popular and not the first choice as development tools for trading applications. However i think this sample application might open a few doors and show people the power and flexibilty of microsoft technologies.
The .NET stock trader application uses:
- Service-oriented, n-tier design with ASP.NET and WCF.
- NET 3.0 with Windows Communication Foundation.
- .NET Enterprise Application Server Technologies.

IObjectReference interface.
Here's an example showing how it can be used:
[Serializable]
class S : IObjectReference
{
int i;
static S S5 = new S(5);
S(int i) { this.i = i; }
public static S Get(int i) { return (i == 5) ? S5 : new S(i); }
#region IObjectReference Members
public object GetRealObject(StreamingContext context)
{
return Get(i);
}
#endregion
}

Indexing by integer: Array vs List vs Dictionary
So i just wrote something to check it. (See the results below:)
using System;
using System.Collections.Generic;
namespace ConsoleApplication1
{
class LookupPerformanceTest
{
static void Main(string[] args)
{
// ten million
int iterations = 10000000;
string[] array = new string[iterations];
List
Dictionary
int now = Environment.TickCount;
for (int i = 0; i < now =" Environment.TickCount;" i =" 0;" now =" Environment.TickCount;" i =" 0;" now =" Environment.TickCount;" i =" 0;" s =" array[i];" now =" Environment.TickCount;" i =" 0;" s =" list[i];" now =" Environment.TickCount;" i =" 0;" s =" dictionary[i];">
Results (running in Release mode)
Array population took: 94ms
List population took: 141ms
Dictionary population took: 719ms
Array lookup took: 15ms
List lookup took: 32ms
Dictionary lookup took: 593ms

Team System Unit Tests and Deployment Items
The files to be deployed with the tests have to be setup so that the tests can run successully on local machine and also on the build machine. Data files such as .cvs, .xml files etc. usually sits in the project directory along with everything all of the rest of my code files.
However the tests when run on the build machine fail because the files cannot be deployed to the "out" directory of the test results. I get a file IO exception – my .Xml file could not be located.
To make it work i had to do 2 things:
- I select my data files in the solution explorer, and look at the properties window. I can then find the "Copy to Output Directory" setting and change it to "Copy always".
- Secondly "DeploymentItem" attribute has to be applied to the items to be deployed other than the test assemblies.
You can use either absolute path or relative path to specify the location of the deployment files.
If you are using MSBuild and TeamCity for build, then you have to use a realtive path rather than the absolute path to make it work, because msbuild on the server uses relative paths as configured usually in the .build file.
To add a path for a deployment item please follow the following steps (as it is the easiet way to do so):
Select a test in the Test View window or in the Test Manager window.
Press F4.The Properties window for that test is displayed.
Click the Deployment Items property. An ellipsis (...) appears in the value column.
Click the ellipsis.The String Collection Editor dialog box is displayed.
Before the test is run, type a path to a folder or a file that you want to have copied to the test deployment folder. Press Enter and type additional paths to specify additional folders and files to be deployed.
Click OK.

Evaluating .NET/J2EE for your Enterprise Applications
I found a very good site which contains extensive materials designed to help you evaluate Microsoft .NET vs. J2EE application server technologies. It contains downloadable whitepapers, benchmark comparisons, and sample source code.
Evaluating .NET vs. J2EE
Well I am sold on .NET for a long time now. I hope the link above helps to make your decision easier.

Microsoft Silverlight launched
If you’ve got the time, I’d recommend (though i havent done it myself yet, but i wil be doing it today evening) watching the Mix keynote video (warning it’s 2.5 hours). In this you’ll get an overview of Silverlight, the cross platform CLR, ruby in the browser, and some very, very cool demos.
You can download silverlight from Microsoft site.

Asynchronous Programming Model - 2.0
I have been reading about the Asynchronous Programming Model in Jeffrey Rithcer's book CLR via C#. I have really enjoyed reading it and i thought of writing something about it.
The Asynchronous Programming Model (APM), as implemented by Delegates, consists of three parts:
- BeginInvoke,
- EndInvoke and
- Rendezvous techniques.
BeginInvoke starts an algorithm, impelmented via a method, on a new thread. EndInvoke retrieves the result of that method. The Rendezvous techniques allow you to determine when the asynchronous operation has completed.
There are three different types of Rendezvous techniques you can use to retrieve the results of an asynchronous delegate invocation
1. Wait Till Completion
2. Polling
3. Method Callback
// a delegate for a method that takes no params and returns a string.

Google vs. Microsoft: reality check
Why Google IS Afraid of Microsoft, Big Time
HIGHLIGHTS FROM THE ARTICLE:
Microsoft pummels Google in the “In-Game Advertsing” space. How? Google buys a small San-Fran company to meet the challenge. Microsoft buys the world-leader in the industry for In-game advertising.
Microsoft delivers a solid uppercut in Voice-activated local directory assistance. How? Google announces an experimental service that may not be available at all times and may not work for all users. (Cute) Microsoft acquires TellMe Networks. Heard of them? Most likely, you’ve been using them for the longest time. Almost half of all directory assistance calls are processed on TellMe’s voice platform, and roughly one in three Americans use Tellme every year to get things done.
Assertion that Microsoft's 'Dead' Doesn't Compute
QUOTES FROM THE ARTICLE:
“When a software runs more than 90% of the desktops on the planet — and will for the foreseeable future — it's simply not dead.”“Windows runs on the vast majority of desktops in the world; Linux and OSX make up less than 10% combined”(Microsoft) “…earned $12.6 billion after taxes in its last fiscal year.
Well this article was written by a guy who currently works for Microsoft (you might have guessed that) and is an ex-googler

private void SetupBindings()
{
BindingList
new BindingList
orderBindingSource.DataSource = orderList;
BindingList
new BindingList
customerBindingSource.DataSource = customerList;
BindingList
new BindingList
employeeBindingSource.DataSource = empList;
}
Thus i reckon .NET winforms provide great support for databindings and it is one of the best options to use.

My new PC with Vista Ultimate
Windows Vista Ultimate is surely ultimate. It is mind blowing. my favourite key is the windows key and tab, to show multiple windows. The gadgets are obviously cool.
I arranged a short "Windows Vista Launch Event in Croydon". It was nothing official, i just named it as such. My collegaues came over to my palce after work and played around with vista. Even non technical guys are coming today evenning to have a look. Everyone's welcome to come and have a look.....

Creating custom cultures in .NET
With CultureAndRegionInfoBuilder class you can define a custom culture that is new or based on an existing culture and region. You can specify the culture and region information for example the associated language, sublanguage, country/region, calendar, and cultural conventions to great detail by using specific CultureInfo and RegionInfo classes. The custom culture can also be installed on a computer and subsequently used by any application running on that computer.
I highly recommend using this feature in .NET to create custom cultures for the application.
