Windows 7: How to edit the boot menu

There's no built in tool in Windows 7 to change the boot menu. However if you need to change the default boot OS to be XP instead of windows 7 or you need to change that ugly "Earlier operating system" line to a nice "Windows XP", or any other boot menu related task, you can use a small free tool called EasyBCD.

IMPORTANT:
If you need to rename the "Earlier.." to "Windows XP" or something, first make sure the XP partition is visible in Windows Explorer. If not follow the instructions in How to add the missing XP partition, and then do any changes.
(When I installed Windows 7, I had my XP in the boot menu but it was not visible in Windows Explorer; using EasyBCD then made my XP not bootable. Adding the partition to exporer and then running EasyBCD fixed the issue).

Windows 7: How to add back the missing XP partition

If you find that your Windows XP partition is not shown in Windows 7 (beta), you can add it as follows:
* search for "computer management" in the program search box and launch it.
(or via Control Panel> Administrative Tools> Computer Management)
* under Storage> Disk Management you should be able to see the missing XP partition (without a drive letter)
* now right click> "Change Drive Letter and Paths", and specify a drive letter.

now you should be able to see the XP partition in Windows Explorer.

A quick look at Google Chrome browser

Today morning I downloaded the chrome browser for windows and gave it a quick spin. Since I run linux, I had to try it in a virtual machine - VirtualBox running Windows XP.

It was a small download in two parts: First the installer, which then downloads the actual application. Installation was smooth and fast. I was up and running in 5 mins.

The very first impression on looks - Wow!. very sleek, clean, and simple. Minimum space taken for the frame and other non-viewing areas. I really liked it. +1 for the looks.

Next I tried the address bar to see if it was as good as firefox's "awesome bar".
Nop, not that good. I tried training it for gmail, which I use a lot. In firefox, aftergoing to gmail about 2,3 times, it 'learns' the page, and next time when I start typing 'gmail', the first entry in the dropdown is the gmail url. But in chrome, it's always the third entry. The first entry is always 'search for gmail'. Takes more key presses for me to select the url. Not very smart. -1 for the address bar.



Next I tried facebook, to test the 'super fast' V8 javascript engine. Chrome claims it to be very advanced, very fast and very responsive.
So I went to facebook, and tried to view an image. Chrome just froze for about 4 seconds taking 99% CPU!!.
However Chrome was specially designed to handle this kind of scenarios where a page misbehaves, and has a built-in 'Task Manager' where we can see which page is misbahaving and kill it. So I tried it. Alas! It wasn't a specific page but 'chrome' itself that was misbehaving and taking 99% CPU; and it couldn't be killed from chromes task manager. Chrome simply failed at one of it's primary goals!. Anyway what was chrome doing taking 99 CPU? maybe it was doing some advanced calculus to figure out the most optimum path to be 'super responsive'!. -9 for overall performance.
(maybe this had something to do with me running it in a VM; but I don't see how)



Next, the 'Most Visited Pages' available on a new tab. Very much like Opera's speed dial. Not a feature I really liked, but it was ok. However it had this glitch where it would show me gmail twice; Not very smart.

I'll wait for the linux version of chrome, and try it out. I really hope google irons out the theses wrinckles before they do.

Trying OpenSolaris 2008.05

I needed to do some performance analysis on some applications for my MSc project. So I wanted to try the latest SunStudio12 with D-Trace. I downloaded the OpenSolaris 2008.05 image, burned on disk and tried to install on my Athlon64 3000+.

Unfortunately I couldn't even get to the first screen of the installation. OpenSolaris just failed on me giving some weired errors. After doing a lot of googling, I figured that OpenSolaris just couldn't work on my SATA drive!
I have installed XP, Vista, Fedora, and Ubuntu on this machine without any hickups and OpenSolaris was the first modern OS to fail on it!.

Next I tried to install it on my laptop but alas! it couldn't recognize logical partitions on an extended partition. So much for OpenSolaris.

I have to get this done somehow, so my next attempt will be to borrow an old IDE disk from a friend and try again. I'm sure there'll still be 101 problems before I actually see the first performance graph on SunStudio.

getting ADSL USB modem working on Ubuntu Linux

Here are the steps I took to get my ADSL USB modem to work on Ubuntu.

Details:
Country = Sri Lanka (ISP = SLT; uses PPPoE)
Modem = Aztech ADSL USB Modem (DSL206U) (chipset = ADI Eagle II)
OS = Ubuntu Linux 8.04 (Hardy)

Steps:
* first have a terminal open and tail the syslog. (to see whats going on)
$ tail -f /var/log/syslog

* using synaptic package manager install br2684ctl (required since my ISP uses PPPoE)
(search for br2684)

* find and download the firmware for the modem chipset (Eagle-II in my case)
--- deprecated; use the .deb below instead ---
(firmware => ueagle-data-1.1.tar.gz)
(http://eagle-usb.org/ueagle-atm/non-free/ueagle-data-1.1.tar.gz)
* install firmware:
$ tar -xvzf ueagle-data-1.1.tar.gz
$ sudo mkdir /lib/firmware/ueagle-atm
$ cd ueagle-data-1.1/
$ sudo cp -a * /lib/firmware/ueagle-atm
--- update(17-Nov-08) ---:
Now there's a .deb which can be directly installed.
http://eagle-usb.org/ueagle-atm/non-free/ueagle-data_1.1-2_all.deb

* plug-in the modem; check if the firmware loads (in the syslog tail output).

* edit the connection file:
$ sudo gedit /etc/ppp/peers/ueagle-atm
type in the following:
user "myusername"
password "mypassword"
plugin rp-pppoe.so
nas0
noipdefault
usepeerdns
defaultroute
persist
noauth

* edit chap:
$ sudo gedit /etc/ppp/chap-secrets
add this line:
myusername * mypassword *

* edit pap:
$ sudo gedit /etc/ppp/pap-secrets
add this line (same as for chap):
myusername * mypassword *

* now create dial script to dial the modem.
$ gedit dialSLT
type in the following:
#!/bin/bash
sudo modprobe ppp_generic
sudo modprobe pppoatm
sudo modprobe br2684
sudo br2684ctl -b -c 0 -a 8.35
sleep 3
sudo ifconfig nas0 192.168.0.1 netmask 255.255.255.0 up
sleep 5
sudo pon ueagle-atm

* set exec permisions for the dial script and we're done!
$ chmod u+x dialSLT

* now to dial the modem just type:
$ ./dialSLT

// -----------------------------------------
important:
* in case the connection drops, do the following before redialing:
$ sudo poff ueagle-atm
$ sudo ifconfig nas0 down
$ sudo killall br2684ctl

Startup delays in today's software

I have been using computers since the days of the 8086 machines, and have seen computer hardware grow in power and software applications grow in features and productivity.

Seeing all that growth, I have come to believe that any modern day computer should be able to startup, boot and be ready for use within a second or two. Unfortunately it's not the case.

My dual core laptop with 1GB memory can be considered a decently powerful machine. Nevertheless it takes a painful 40 seconds (even after optimizations) to startup and be ready. When I want to check mail and fireup MS Outlook 2007 (which I have to use due to company policy), it takes a good 10 - 20 seconds before it finishes crunching the disk and is ready to use. Also during this time I pretty much can't do anything else due to the disk activity. If I need to type in a new document and fireup MS Word 2007, it takes around 5 - 10 seconds before I can start typing. If I need to jot down something quickly and fireup MS OneNote, it takes around 4 seconds before I can type it in.

The problems are not all about MS applications. Linux startup is just as bad as Windows; OpenOffice 2.0 startup takes even longer than MS Office; Thunderbird startup is no breeze and Firefox (3 beta 5) takes a good 4 - 8 seconds to startup (I admit I have a couple of add-ons installed though).

Here's my point: Even with powerful hardware and decades of software development, we still don't have software that simply starts up and runs as quickly as we need them to be.

The contra-argument here is that features come at a price, and a more feature rich application would take longer to start. I strongly disagree.
However feature rich an application is, all those features will never be used at once. In fact some features may never be used by some users. Hence it's a waste to load all those features during the startup of a program (creating delays and disk crunches).

In my opinion there's not enough emphasis on startup time in today's software, and here are my suggestions for improvement:

1. The software industry needs to consider startup time and startup cost as critical quality metrics and pay more attention to it (specially in general productivity applications).

2. Software design patterns for general on-demand feature loading should be established and popularized.
- This can be simple on-demand feature loading or delayed feature loading based on idle computer resources. (eg: Diskeeper's InvisiTasking).

3. Better support from the operating system for faster application startup.

The IT Workforce in Sri Lanka

The IT workforce in Sri Lanka mainly comprise of IT Managers, Business Analysts, Project Managers, Software Architects/Software Engineers/QA Engineers, and Hardware/Network/System Engineers. Almost all of these categories are highly in demand, but short in supply.

Hardware, Network and System Engineers demand at least a Diploma in IT and several years of hands on experience; Software Engineers, Architects demand a Degree in IT and extends over to Masters level as well. IT Managers, Project Managers are expected to have at least a Management Degree along with an arsenal of communication and management skill sets.

When considering the demand and supply of the IT workforce, an obvious observation is that Sri Lanka doesn’t have the in-house capacity to produce the required IT workforce to meet the demand; This is the case, even when all the IT Engineers graduated from all our universities, combined with private institutions output are taken. However the quality of this small output can be considered to be on par with (if not better than) global IT workforces.

The Government has a huge responsibility in implementing a national strategy that will increase the annual IT workforce output continuously. Building new Universities specializing in IT, expanding existing universities to produce more IT workforce, encouraging/helping private IT institutes, introducing more IT related subject matter at school level, as well as to broaden the IT awareness among the public in general, are some of the measures that can be taken by the government. India’s national IT strategy and its success gives us a good indication of what needs to be done by the government to increase the IT productivity as a nation.

Universities have the responsibility of improving the quality of the IT workforce produced, as well as to broaden the IT awareness of the general public. Universities need to play a larger role in inspiring the younger generation at the school level, and to help them understand the opportunities available in the IT industry and the many benefits it can provide. In my opinion the current inspirations and ambitions towards the IT industry, at the school level, is very limited and needs some major uplifting. This can be done by Universities, by organizing more interactive sessions, workshops, presentations etc. with schools.

Also the Universities have a major role in improving the IT awareness of the general public and to cultivate a more favorable perception towards IT. I feel that the current IT exhibitions etc. done by the Universities are too technically oriented, and need to focus more on the people aspect and the business aspect of IT, demonstrating the opportunities available, the financial benefits, how IT is actually helping Sri Lankan businesses to grow etc. This improvement in perception, cannot be done alone by the Universities, and needs the government support.

The IT companies are the places where the IT workforce will actually engage in productive work and produce tangible benefits. Hence they have a high responsibility in grooming the IT workforce to reach global quality and efficiency standards. This can be done by having quality training programs, continuous improvements plans etc. IT companies also have the responsibility of guiding the Universities in bridging the gap of the produced graduates skills and the actual industry demands. For example the IT industry demands very strong team playing skills along with technical skills, so producing graduates with only a high technical skill set will not suffice. Programs like “Are-You-Ready” at the University of Moratuwa, helps in this matter.
