Update Your Samsung Galaxy ACE GT S5830i with Android 4.1.1 Jeally Bean

  When it comes to custom ROMs firmware, the Galaxy Ace users can choose from a long list of updates, though they should be aware that not all the OS improvements are working properly. Also, not all the ROMs can be installed on both versions of the device, the S5830i and the S5830, therefore you must check the compatibility first. Anyway, today, I will teach you how to update the S5830i variant of the Galaxy Ace to Jelly Bean 4.1.1......

Tcl and OTcl Tutorial For NS2 - Procedures

Procedures Procedures are an essential component of Tcl and can be used to make programming ns simpler. As in any functional programming language, procedures can be used for repetitive tasks, or simply to logically break down the tasks in the program.Procedures are defined in Tcl as follows: proc proc1 {} {    puts "in procedure proc1"} This defines a procedure that takes no parameters and prints out "in procedure proc1". To call this procedure proc1 can be used.A procedure with parameters can be defined as follows: proc proc2 {parameter1} {    puts "the value......

Tcl and OTcl Tutorial For NS2 -Loops and Conditional Statements

For loops For loops are very useful in ns and can be used in conjunction with arrays to easily create larger network topologies. To generate 100 nodes, the following code can be used: for {set i 0}{$i < 100}{incr i} {    set n($i) [$ns node]} While loops These are very similar to for loops. The syntax is set i 0while {$i < 10} {    set n($i) [new Node]    incr i} If statements If statements are very simple if {$i < 10} {    puts "i is less than 10"}if {$var2 == "Tcl Variable 2"} {    puts "var2 = Tcl Variable......

Tcl and OTcl Tutorial For NS2 - variables and arrays

Variables and arrays Defining a variable in Tcl is very simple: set var1 1set var2 "Tcl Variable 2" The variables can be referenced by prefixing the variable name with a $. For example to print the above variables, we can use puts "var1=$var1, var2=$var2" Any situation in which you require that the value of the variable be used is one in which the $ prefix should be added to the variable name. In some situations, it is necessary to use the variable name directly. For example incr var1 can be used to increment var1. I guess you can think of it as the difference between call-by-reference and......
