A lot of people may ask themselves when developing databases when to use the UNSIGNED keyword.
So what’s the difference between a “signed” integer and an “unsigned” integer?
An “unsigned” integer can not be negative but the upside is that you can have a bigger range of positive numbers.
I think the following types explain themselves:
Tinyint -> Signed range -> –128 to 127
Tinyint -> Unsigned range -> 0 to 255
Mediumint -> Signed range -> –8388608 to 8388607.
Mediumint -> Unsigned range -> 0 to 16777215
Bigint -> Signed range -> –9223372036854775808 to 9223372036854775807
Bigint -> Unsigned range -> 0 to 18446744073709551615
That’s should explain it. Short but informative… hopefully!
The other day I started working on a Twitter project and what I need to do is to scan Twitters public timeline and get a certain amount of tweets from a certain user. On top of that it needs to be filtered by hashtags.
After browsing the net for a little while I found a fantastic class on scriptplayground.
I implemented it in my project and it worked like a charm.… until I wanted to filter out ReTweets. I simply couldn’t find any additional parameter for the Twitter Search API that could do that for me. I mean I tried to put –RT and all that sort of stuff into the search-call but it simply didn’t work out for me.
Maybe I did something wrong. If so, I would highly appreciate a comment that will widen my horizon!
So I decided to extend the class myself and provide it for anyone who might find it useful.

I was just browsing for the latest version of Tortoise SVN when I stumbled upon this neat little tool which implements a feature into your Windows 7 OS that will be available in Windows 8 (or what ever they are gonna call it).
It changes your windows aero color depending on the overall colour of your wallpaper. Check it out, it works like a charm!
Here it is… my new design with a custom header that I created last night.
The design was originally created by patembe.

After searching the internet for something trivial like the sorting a multidimensional array I found the following solution.
Today we will look into getting a proper setup for connecting a Flex 4 application to a .NET backend.
I have found several tutorials on that topic on the internet but none of them covered the whole process in one go. So I had to gain my knowledge by combining what I’ve learned from several different tutorials and making some guesses in the end to make it work.
To spare you this — sometimes tedious — process I will guide you through the installation and configuration of Flex 4 with FluorineFX to connect to a .NET backend.
Let’s get started.
You are here because as a WordPress plugin developer you are experiencing the following error:
The plugin generated 8 characters of unexpected output
during activation. If you notice “headers already sent” messages,
problems with syndication feeds or other issues, try deactivating or
removing this plugin.
I solved the issue by doing the following…
I developed this web application for a client of mine. It was running fine on a server but now they want an offline for presentation purposes.
So they asked me to do some changes (load local pictures etc…) and deploy an offline version.
So while doing that I discovered the following error:
Flash Security Error — fpdownload.adobe.com
This error occurs when I tried to open the HTML file that embeds the SWF in my browser.
I am just playing around with Twitter’s PHP Library twitterlibphp and created this little application.
You can see the results here.
