VS2005 Web Application

In Visual Studio 2005, ASP.Net web applications are not projects any more – they cannot be found in the “New Project” dialog box. Instead it stands on its own in the File menu, as a “New Web Site”.

J2ME – CLDC 1.1 + MIDP 2.0

Primitive doubles are now supported on CLDC 1.1. Although the built-in java.lang.Math also cater to double functions, some of the essential Math methods are missing (namely pow, exp, log, round).

Luckily there are always kind people who create such packages for public use. Do note that it is not free for commercial purposes.

Sun Solaris Installation

Had a chance to install Sun Solaris 10 on a Solaris machine today with a 64-bit AMD Opteron processor. The machine came installed with Windows XP 64 bit (first time seeing it too) but we didn’t have the password to access the system.

The installation was quite straightforward with its auto-boot GUI installation wizard, although it asked damn lots of questions from network settings to locale BEFORE asking the user to assign disk space for the installation. (imagine the situation when you configured everything but did not have enough disk space for it.

The end result of it is a unix system (with /etc /var /bin), and two GUI apps (CDE – Common Desktop Environment & Java Desktop) which are Windows-like GUI systems. The CDE resembles more like X-Win while Java Desktop mimics Windows closer (with a “Start” button and taskbar). Configuration is still as weird as normal Unix, since I’m not that Unixy.

The weirdest part was before installation we used a “self-burnt” DVD to try install Solaris 10 x86 Update 2. The CD-ROM boots and stucks at “Loading stage2…”. Google say its a known bug when installing from SCSI DVD-ROM drives but ours is IDE (I think). Popping the CD out throws us into GRUB (GRand Unified Bootloader), but we can’t start the install wizard despite trying those “boot” and “kernel” commands.

In the end we resorted to using an “older” original version of Sun Solaris 10 x86, also DVD.

Tidbits:
– ifconfig = ipconfig
– DNS nameservers is set in etc/resolv.conf

UltraVNC

UltraVNC is a flavour of VNC — its an open source project in SourceForge. It provides all basic VNC features: connecting to remote machine, perform mouse/keyboard tasks on remote machine, transfer files, etc. It even allows connection via HTTP using a Java Viewer, possibly allowing it to cross firewalls.

Configuration is straightforward with a single password, but I’ve yet to see if it can integrate into the Windows Authentication.

So far UltraVNC has served me well and hasn’t given me serious problems. Server installs cleanly, and the client is light and doesn’t even need installation. A simple unzip and the viewer can be run.

VMWare

VMWare allows you run an OS inside your OS, eg. Run Linux in your Windows machine, or Windows in Linux. A very useful program I think.

I installed my WinXP Pro in an WinXP Pro machine, and used the VM as a test platform to try out software without corrupting my actual system. Can be also used to test if some software is spyware-like. Once I made a complete installation, I made a “copy” of the OS so I have a clean WinXP installation anytime.

Working within the VM is exactly like having another machine, much like what VNC provides, except the VM is not any physical machine anywhere else. The VM has its own BIOS, hard disk space and IP address… I could ping from my host to VM and VM to host, very real.

The only annoyance was trying to transfer files between my host OS and the VM. This is especially necessary when I want to copy installation files over. Shared folders didn’t really work out, so I had to use another machine’s shared folder. Perhaps there exists an easier way for file transfer from host to VM.

I give VMWare 10 out of 10.
