Text wrap at 80th colum:

#include using namespace std; int main(void){ string input; int count = 0; while(!cin.eof()){ cin >> input; if (count + input.length()<= 80 && count==0){ cout << input; count +=input.length(); }else if(count+input.length()<=79&&count!=0){ cout << " " << input; count 1+=input.length(); }else{ cout << endl; count=input.length(); cout << input; } } cout << endl; }

List + Info

Slagz now supports list of installed packages plus info for particular package(swaret). Thanks to QTSwaret for the hints. Here is how I parse the name of tha packages to extract the version: while ( (fi = it.current()) != 0 ) { QString *myFileName = new QString( fi->fileName() ); for(int a=0;alength();a++) { QString temp = myFileName->section('-',0,a); if (temp.find('.')>0){ newPacket = myFileName->section('-',0,a-1); break; } } QString PacketVer = myFileName->section('-', -3, -3); QString Installed = "yes"; if(! myFileName->startsWith( "." ) && ! myFileName->startsWith( ".." ) ) new QListViewItem(listPackages,newPacket,PacketVer,Installed); ++it;

Slagz redesigned

Looking at some projects available I decided to go with a slightly different approach for slagz. Instead of a bunch of menus on the window in Advanced mode, right click will be used. To override the right click the rightButtonPressed signal is used from the listPackages widget with the showMenu() slot(custom widget) . The connect looks like this: connect( listPackages, SIGNAL( rightButtonPressed(QListViewItem*,const QPoint&,int) ), this, SLOT( showMenu() ) );

for N nodes n*(n-1)/2 wires are required (bidirectional wires) - started with IBM - not very good solution

Now days packet switching is used. Using a ring, for n nodes n wires are used.

scheduling:
with multiple people working on multiple tasks it is better for each person to work on a separate task instead of more people working on a single task.

Updated System Design & Updated Time Table

In the downloads section you can now find the Updated System Design & Updated Time Table presentation in the typical 4 formats. HTML version is available here.

Preliminary System Design + Timetable

First timetable for the project + Preliminary System Design presentation was added in the Downloads section.

Java and C++ compared

Java and C++ are both very similar and very different depending on the situation.
On the basic programming level of for loops, if-else statements etc, both languages follow the same structure.

On a higher level, things are different.
In C++ we can have stand along functions, but in Java they must be part of a class. In C++ multiple inheritance is available, in Java not. C++ allows for operator overloading and Java does not.

Java vs C++ Notes & Time management

not that important to overload an operator

Main differance - manual return of memory space in C++ against Garbage collector in Java. There is no precise timing in Java because of the GC. To solve : put native code on the important places in Java program. But than have to be compiled platform by platform.

Project is aprooved!

After dealing a little with SF they have aprooved the project and now the infrastructure is ready.
The url is: http://www.sf.net/projects/slagz/
Fist two presentations are done, Next week a design will be created and tasks will be assigned.
