I love hg.

No no.. not the element.
I though I would share the rollback thing hg has and how neat and easy it is to use.

Learn Ada, not C++.

Its common these days for students to learn C++ , and many apps are indeed written in C++ as a side effect of the above endless circle.

However, The truth is C++ is not all that great really.

**But why Ada..**

Over the next few blogs I am going to just throw(hehe) out a few examples and you can see for yourself.

The important thing here is to learn both before making calls on what is better for what. Clearly everything has its place. Although its good to know a little more then just past your nose ;)

Here goes...

Exception handling;

As you know exception handling consists of three components, the
exception (derr), raising the exception and handling the exception.
However, In C++ there is no exception type. When you raise an
exception you pass out any sort of type while selecting the exception
on its type. In Ada, there is a 'psuedo-type' for exceptions.

So here is some example code:

In C++

try {
 my_func();
} catch (declaration) {
 clean_up();
}

In Ada

begin
 my_func();
exception
 when ident => clean_up();
 when others => clean_up();
end;

OK, now here is a example where we call a function which we know may
raise a particular exception. Although it _may_ raise one that we
don't know about so we *must* pass everything else back up to whoever
called the function.

try {
 func_call();
} catch (const char* string_exception) {
 if(!strcmp(string_exception, "what_we_are_look_for")) {
 handle_it();
} else {
 throw;
 }
} catch (...) {
 throw;
}

OK, now in Ada:

begin
 func_call();
exception
 when what_we_are_look_for => handle_it;
 when others => raise;
end;

Yes it even looks better !

This shows how much safer the Ada version is, we know exactly what we
are waiting for and can immediately process it. In the C++ case, all we
know is that some kind of exception occured of type 'const char*' had
been raised, we must then check it still further before we can handle

it !

I will try to keep these short, so that is it for now.

Edward O'Callaghan.

VirtualBox 2.0.4 is out !

Nothing really very interesting.. Still no USB host support for Solaris :(
When is this going to be fixed Sun ?

Brand new USB pen.

So while I was shopping for caffeine supplements in the *super* market I saw a 2GB USB pen for 5$AU. As it had "Linux support" on the front over I though I would buy it out of principle and the fact that I need some flash storage.

Here is what I did when I plugged it in:

Intel(r) Pentium(r) Dual CPU E2180 @ 2.00GHz
[edward@SXCE-Workstation]:/export/home/edward:~>/usr/bin/rmformat
Looking for devices...

[edward@SXCE-Workstation]:/export/home/edward:~>/usr/bin/pfexec umount /dev/dsk/c2t0d0p0

[edward@SXCE-Workstation]:/export/home/edward:~>pfexec zpool create MYDATA c2t0d0

[edward@SXCE-Workstation]:/export/home/edward:~>zpool status
pool: MYDATA
state: ONLINE
scrub: none requested
config:

MYDATA ONLINE 0 0 0

errors: No known data errors

pool: rpool

config:

errors: No known data errors

[edward@SXCE-Workstation]:/export/home/edward:~>zfs list | grep -i MYDATA
MYDATA 69K 1.83G 18K /MYDATA

I can only conclude one thing from this.
Solaris needs to support auto mounting of usb pens that are formated with the ZFS FS.

Scons for Solaris - lol, no really..

Due to popular demand, here is a spec file to build Scons for SXCE and Solaris 10.
OpenSolaris is useless for building anything past HTML thus I don't care if it does not work on OpenSolaris.

Thanks for everyones feedback on my last post.
The following can be build as follows; N.B. you will need CBE installed.

First save the below file in a file called EVOscons.spec
Then follows this;
