Knowledge is inside
Blind Search is a very interesting site which lets you search in Google, Yahoo and Bing simultaneously, but with a particular quality: without showing who is the provider of each result list. So you must vote your preferred results before knowing!
They have published here the results of the first 8 weeks from the site’s opening (the article is from July). Keep looking at the home page for more current news.
Thanks to Fepe for the link!
I’ve just updated the Move Facebook Events Box to Top to the version 1.1 to solve the problem that made the events box not going to the top sometimes when loading the page or reloading.
Please visit the original post to download the updated version.
Everybody knows the Pinball game that appeared with Windows 95 Plus!… It’s still in current Windows versions…
Although it may seem incredible, there are still some fanatics of this game…
I’ve made this program in 1999 (some time ago 8-)) to let you modify the High Scores so you could make those fanatics believe you had beaten them…
(You should be a little more subtle than me)
Since I’ve been having lots of visits in my wxWidgets version of the Celsius to Fahrenheit converter, I’ve decided to prepare an online javascript version which lets you easily make the conversion.

Facebook has got very interesting features… One of them is the possibility of having a reminder of your friend’s birthdays and events you have subscribed to…
But (there’s always a but 8-))… They’re not in a very handy place…
So… I’ve decided to make a script to move them to the top 
This is a very good video I’ve seen some time ago. I think Fepe sent it to me. It’s from Tom’s Hardware Guide.
It shows what happens to different CPUs when you remove their heatsink.
This is a tool I’ve made two years ago to solve a problem a friend of mine had. He had at his work a bunch of Word and Excel files created in different computers and wanted to cleanup their properties so they didn’t show the configured Author/Title/Subject/etc. tags.
This would have been a simple problem to solve if there were a few files… They could be cleaned up manually…
But there were lots of them!
So… I made this tool
Every C++ programmer knows that the standard library has a string class. But, while learning, it’s a good idea to know how to develop your own string class.
That’s why I made the String class. It’s not intended for professional projects (for them, you should use the standard library’s string), but as help to learn C++.
class String
{
char *m_pszString; //Allocated buffer
int m_nAllocated; //Allocated length
public:
//Construction and destruction
String() { /* ... */ }
~String() { /* ... */ }
//Copy constructors
String(const char *pszString) { /* ... */ }
String(const String& rsString) { /* ... */ }
//Operators (assignment)
String& operator=(const char *pszString);
String& operator=(const String& rsString) { /* ... */ }
//Operators (concatenation)
String& operator+=(const char *pszString);
String& operator+=(String& rsString) { /* ... */ }
String operator+(String rsString);
//Operators (comparison)
bool operator<(String sString) { /* ... */ }
bool operator<=(String sString) { /* ... */ }
bool operator>(String sString) { /* ... */ }
bool operator>=(String sString) { /* ... */ }
bool operator==(String sString) { /* ... */ }
bool operator!=(String sString) { /* ... */ }
//Operations
void Clear();
String Lower() { /* ... */ }
String Upper() { /* ... */ }
//Information
int Length() { /* ... */ }
//Cast operators
operator const char*() { /* ... */ }
protected: //Helper functions
/* ... */
};
//Output e input
std::ostream& operator<<(std::ostream& oStream, String& rsString);
std::istream& operator>>(std::istream& iStream, String& rsString);
This library is the C++ sequel to the cMemDbg.
Just as the cMemDbg, it is a very easy to use library which can help you to detect and track memory leaks.
Its usage is very similar to the cMemDbg, but with support for the C++ operators (new, new[], delete and delete[]).
There are lots of solutions for this on the net, but this one has the particularity of being really simple to implement.
