WordPress- how to implement Syntax Highlighting
1
Some while ago, I started publishing code on this website. On that days I used the free WordPress webhosting. But I wasn’t content with the representation of it. After some time, I moved my site to a payed hosting, where I could implement any plugin that I liked.
BNR exchange rate
0 
In this global crisis, nothing is more useful than a good chart to watch your money as investment. That’s why I created a special page which collects freely available exchange rates from BNR (National Romanian Bank) and presents them in a graphical form. This way, the viewers of my website will always be on the edge with exchange rates, as soon as BNR posts them (usually around 13:00 GMT+2).
The main challenges were:
- Building a php script to parse XML, inserting the exchange rates into database. The lack of experience and debugging tools made a huge difference in development time. But all is working now.
- Creating a php script that will daily update the exchange rates, so the users will have the fresh rates at their disposal as soon as possible.
- Design the page that hosts the chart and provide create the appropriate data structure which will feed the chart with data.
- learn to use a very interesting framework of representing data as charts – Google Visualisations
Next steps:
- Offer the posibility to choose among all 30 currencies for which the BNR provides exchange rates.
- implement AJAX for smooth behavior of refreshing the page while user chooses a different currency.
Enjoy!
Forecast on websphere: Flex or Silverlight or AJAX or JavaFX ?
1Lately I had some interesting conversations with few of my developer friends regarding their opinions on which technology will rule the Rich Application Interfaces websites in the future. My strong believe is that there’s room for all four of these as per my experience and actual trends. More over, all these will have a separate slice of the market but overlap at only few areas. Let’s take AJAX as example – it is widely popular for creating rich user experience community building apps, portals, mash-ups and so on. On the other hand, Flex is used more for multimedia rich requirements, interactive maps for example, photo albums, portfolios, games etc. Another technology, Silverlight, is a direct competition to Flex, but its presence is more dominant in the Enterprise applications market.
Adobe’s Flex has a big advantage of running on the Flash platform, inheriting a very wide reach on the internet and having also an integrated support from other Adobe products, like Photoshop, After Effects, Fireworks, Flash, Illustrator. Also some near future upcoming products – Catalyst, Thermo, Cocomo, and more will be closely integrated with the legacy platform. All these are reliable, proven technology in web industry, being leading tools for creating visually rich media, no matter that is composed from images, animations or videos. Besides all, the new AIR version brings even more value by having a desktop version of an app that is integrated with the online one. (more…)
Tweet your ideas through JavaScript
0Do you have a website and would like to post your tweets from it ? Or maybe you want to create a widget that posts weather on your twitter account?
I encountered this situation and overcome it with the following script. It is pretty simple, but beware that JavaScript is run on CLIENT side, thus any code must be sent in clear.Since it is needed that you provide a password for your account, would not be so wise to put it in clear.
NOTE: I use it for a Vista sidebar gadget, so only IE code is below. For FireFox or Opera the modifications are trivial. (more…)
