  • Interconnecting Flex modules

    Adobe Flex 3 has a very interesting component : LocalConnection. The idea behind is that the modules (which runs on client side) might change some data. The exchanged data is not limited at all to simple forms, but can be from a simple String to a XML or Arrays. Few things must be known from the start, but as any technology, only after you learn it everything becomes easy. First of all, the communication can...

  • Objective-C: Use NSXMLParser

    Almost any time you'll need to pull some data from the web. Using Objective-C you have at your disposal a pretty good XML parser - the event-based version. What really means is that instead of building in-memory tree with the structure of the XML you'll have some events raised when the parser encounters a special token - the most usual ones are tag start, tag end and found comments. The parsing goes node by node...

  • Objective-C: allocation and deallocation

    While reading the book by Mr. Kochan (1st ed): "Programming in Objective C" , I noticed that he uses the following code (you can see it at pages 342-344) to explain that the initWithString is preferable to stringWithString because the AddressCard class would own the name variable contents. Also, I don't get any errors making repeated calls to the setName version with the stringWithString...

  • GPS – Global positioning system

    GPS is the oldest one from the frameworks available to the large audience. It isn't the first positioning system, but it is the one with the most success and longevity. It started as a military project in 1957. Because of the cold war, once the Russians sent to space the first man-made satellite, a team of scientists started monitoring its radio transmissions. The crucial discovery was that, because of the Doppler...

    SEO tools and mod_rewrite were out for a while. They do amazing things, like enabling humans to have a crisp view about the contents of a link. Unfortunately, until IIS 7 Microsoft didn't had nothing comparable as default, but some companies struggled to offer this basic service.The two options were the rather cheap IISRewrite and the free ISAPI Rewrite Filter.

  • Objective-C: UIAlert or asking for confirmation

This will be very useful if you want to display some deletion confirmation or ask for user permission to use the camera or GPS sensor.

While iterating in the structure using NSXMLParser, a event-based parser, I kept adding the pairs as name and values...

    Apple’s Xcode : symbol(s) not found at Line Location Tool:0

WordPress – Database backup and restore

Sep 13th

Posted by Radu Poenaru in Others

No comments

From time to time, you’ll need to get a backup of your MySQL database and install it on a different machine – as I needed when reinstalling my Windows 7. I wanted to do something simple, as the last time. But now the database sql file is 11 Mb as opposed to merely 2 MB last time.

But I thought that this would be a breeze for the MySQL interface that I use and enjoy – HeidiSQL. It’s free, easy to use and user friendly. I personally don’t like too much the phpMyAdmin interface from the Vertrigo webserver installation that I use for local More >

Google Visualizations

While working on my idea of presenting on this website also the Romanian National Bank exchange rates (very useful in this crisis time), I end up in choosing a form of visualization.

One might argue that text is good enough, but for me frankly graphs and charts are the best. So I started looking on the internet for free and customizable charting tools.

From the plethora of choices on the web I will present just a few:

1. An interesting tutorial on how to build a chart of your own – it’s the easy way to get exactly what you need done as it More >
