How to auto zoom and auto center Google Maps

Posted in User Interface, Web Programming by Andrei Alecu on the September 28th, 2007

This post discusses how to auto center and auto zoom a Google Map to display all of the markers optimally.

In order to get accomplish this, you have to calculate the center point and zoom level manually via code. Fortunately this is pretty easy to do, you just need to calculate the minimum and maximum latitude/longitude of all of your markers and then get the center point of the resulting area (which will be a rectangle).

Cool new C# 3.0 syntactic sugar

Posted in .NET Framework, C# by Andrei Alecu on the September 21st, 2007

I was recently reading a post on MSDN blogs by Abhinaba Basu about a new feature in C# 3.0 and Visual Studio 2008 (Orcas)—Automatic Properties.

Coming from a Visual Basic background, I never really understood why C# forces you to do some things the hard way, even when it knows by itself what you meant to do, and it could have done it for you in the first place. (more…)

Ditch POP3 and start using IMAP

Posted in Uncategorized by Andrei Alecu on the September 19th, 2007

I was recently introduced to IMAP by a friend. I was aware of IMAP for a very long time, but I never got around to actually using it. We turned to IMAP because had to answer support emails for a website collaboratively without using a ticket system.

Overview of IMAP

Although IMAP was supposed to be the natural successor of POP3, most email servers these days still use POP3. Regular internet users are not very familiar with IMAP, because, as with every new technology, there is a slight learning curve to it. (more…)

BlogRush and how to get targeted visitors for your blog

Posted in Internet Marketing by Andrei Alecu on the September 16th, 2007

You may have noticed the new From the Blogosphere widget on the sidebar, here’s what this is all about.

What is BlogRush?

BlogRush logoBlogRush is a new service by John Reese (an Internet marketing guru—I hate the term guru this will be my first and last time using it) which is kind of like a MLM scheme for traffic building.

When I first heard “MLM” I was kind of suspicious too, and I’m pretty sure most of you are as well, but here’s the thing with BlogRush: (more…)

Vacation in Crete

Posted in Personal by Andrei Alecu on the September 13th, 2007

Sorry for not posting anything this last week, me and my coworkers and friends at Tachyon Labs have been on vacation in Crete, Greece.

Accomodation

We stayed at the Santa Marina hotel in Ammoudara. The conditions were pretty good and the staff was wonderful. There were two fellow Romanians working at the hotel for the summer, and we also met lots of other Romanian people working at shops, pubs and clubs in Iraklion and Hersonissos.

Hersonissos is where it’s at if you’re young and want to have fun, it’s basically the youth town of Crete and the night life hot spot. Ammoudara is a bit quieter and relaxing, catering better for a family vacation.

Trip to Hersonissos

Two days into the vacation we rented a car so we could go to Hersonissos (yes, we’re not nerds, we’re all still pretty young and we like to have fun), and this was pretty interesting. I was the one to drive, and a friend was guiding me using a map that we got from our hotel reception. (more…)

Calling a Windows Service from ASP.NET via Remoting & IpcChannel

Posted in .NET Framework, C#, ASP.NET by Andrei Alecu on the September 1st, 2007

I recently had to design a Windows Service that connects to several game servers via UDP, gathers stats, and then updates a MSSQL database.

These stats were then made available in real-time on a web-site written in C# and ASP.NET.

Before Remoting

For the first version of the application, the web-site and Windows Service were completely independent. The web-site would just query the database and determine, or make a best guess about what was going on inside the Windows Service at that exact time. This worked pretty good, and although the database is now about 1GB in size and growing fast, I optimized it good enough for this to work in real-time without a hitch.

There was some caching going on, thanks to the OutputCache directive in ASP.NET, but surprisingly enough there were no performance issues.

After Remoting

All right, so because I needed to display some extra information about ‘online’ users, that the Windows Service knew about, but the database didn’t, I decided to have a look at .NET Remoting. This was my first time working with it.

These were the issues I experienced (as a Remoting newbie) when rewriting the Windows Service to be accessible via .NET Remoting: (more…)
