Splashtop: Solving slow boot problems

Recently someone sent me a link to splashtop, in context of some work I was doing on Asus Eeepc. Splashtop is a OEM installed OS that boots off a embedded flash/hidden-partition device on your PC. It uses Bootsplash, SquashFS, Blackbox, SCIM and Linux kernel.

Splashtop's raison d'etre is to provide instant-on/off experience to PC. Since PC boot times are slow, most people don't even turn off their machines. Splashtop takes about a second to show it's splashscreen right after BIOS on a Asus notebook. From this screen, you can launch virtual appliance'cified Firefox or Skype or boot Windows etc. One thing to note is that each of these operations in turn may take 5 to 25 seconds.

I wonder if this is a feasible approach to solve this problem. Boot process which involves hardware initialization, OS initializtion, startup application initialization - all of these operations have to take "some" amount time. And we know that most of these are IO bound due to slow d…

LinkedIn has expired SSL certificate!

Today HTTPS certificate expired. Seems they have forgotten to renew it. Quite shameful for a company that promises privacy and security of user’s information.
Here’s what Firefox 3 told me when I visited the website and tried to sign-in.

Logging in bypassing this cert security error is not an option for me. So, for all practical purposes, linkedin is down for me.

Speed: Firefox Vs Safari

This test was done with Webkit's SunSpider JavaScript Benchmark on the latest versions of Firefox 3 and Safari available as of today.

It overall the test results indicate Safari is faster. But the individual results need to be looked at and decided which tests really matter in real world and how they affect our daily browsing speed.

Windows Live Writer On Macbook

Windows Live writer is such a good blogging software that it alone justifies installing vmware fusion+windows on my Macbook. Apple really doesn't have any product that comes anywhere close to Windows Live Writer for blogging. For that matter nobody has.Among all products under Live brand this alone is generations ahead.Keep Rocking!

Switching to OSX

I've got a macbook at work. And for the last couple of days while trying to figure out how to do various simple tasks I have been thoroughly annoyed by this critically acclaimed OS.

This blog summarizes my annoyances very well. Is Apple listening to it's customers? If it wants to get more corporate customers or grow it's market share, they better do something about these things.

htop: more than top. pstree: ps with tree.

I'm a big fan of procexp and other sysinternals tools on Windows. Many people who use those and then come to Linux complain that there are no such tools in Linux. Most people are familiar with top and ps commands. I would like to introduce you to a bunch of utilities on Linux that are very useful while debugging issues. Lets start with htop, a better alternative to top.You can install htop on a yum based system like Fedora, Redhat, CentOS etc with "yum -y install htop" or with "apt-get install htop" on systems that are debian apt based like Ubuntu.htop is much better in displaying the process and resource information than top. It gives a more accurate and clearer picture of process memory usage than top.A screenshot of htop in action:It has many interesting features. It's display layout is refreshing different and nice. It can show tree view, a very important feature to understand the ancestry of a process. In the size column, the MB part is highlighted wit…

More power to OpenID million to over 250 million adoptions in a span of 12 to 18 months for a concept that was born in a small community just 2 years ago without the muscle power of any large corporation is just amazing. More power to OpenID and all open standards - those are the only ones worth calling standards.
