New hardware - planning

My primary workstation is a 3 and a half year old Dell XPS M1710 laptop and it is getting old - the 320 Gb hard drive is getting small and slow, the 3 Gb or RAM (expanded from 2 Gb) look too small and screen is turning brown in one corner. Also dead or dying: keyboard (after cat+coffee incident), built-in speakers, battery, power adapter (twice replaced), DVD writer (rads but does not write any more) and fans (one replaced, one getting louder by the week). Also the video card is a bit slow for nowadays needs.

Test post with an embedded wave

Hello all, the latest craze is the Google Wave preview. I am in, so I am testing how a Google Wave will look when primitively embedded into a blog post using Wavr plugin for Wordpress. And here it is:

Debconf9 photos and banter

A bit more than a week after Debconf9 ended here is a post summarising what I remember about it - for myself to look back to later, for others that were there for a good memory, for those that were not there for insight and for organisers of future Debconfs to improve.

And then there was Debconf9

First I will point to resources that will receive more updates than this blog:


  • My Twitter feed - if I have a bit of info to get out, I'm more likely to tweet it out there, rather than writing a blog post about it.

  • #debconf9 Twitter feed - me (and other people) posting Debconf9 related info on Twitter are likely to use this hashtag to tag the information ( Identi.ca tag feed is also useful).

  • My photos on Flickr - I will be uploading photos and adding them to this set as the event progresses. A few are up already ;)

Google Wave

So, the latest buzz on the web is all about Google Wave. I would urge everyone developing stuff for the Internet and technological people depending on the Internet for their daily work, to watch that introductory video. The concept is frankly mind-blowing. If this is done right and embraced by all the right people, Google Wave could be the new platform concept that could be used to create new generation of email, instant messaging, collaboration software (CMS, wiki, Sharepoint, workflow, ...), blogging software and forum software and do all that while integrating back with current technologies, like Twitter and RSS feeds.

Re: HOWTO prep for migration off of SHA-1 in OpenPGP

Daniel says that we should move away from SHA1 by switching hash algorithms for signatures and generating keys that use at least SHA256 from SHA-2 family. I have been bitten by non-default GPG options before. So I propose that we do a security release of GPG that changes the defaults of key generation and key signing in such ways that SHA-1 algorithms are not used by default for any operation, unless a backwards compatibility option is used.

How to survive a coffee cup - guide for laptop (and cat) owners

Yesterday my cat spilled a full cup of hot coffee on my 2k$+ laptop. Today, there is no trace of the incident and the laptop is working perfectly again. This is partially thanks to luck, partially to Dell laptop engineering and partially to my instinctive actions within first 10 seconds of the incident. I will recap it here so that if you happen to have a mishap of such kind you would know what to do to save your laptop.

iPhone review from a free software guy

I got an iPhone on the very first day it was available officially in my country. I have used it every day since then and am now ready to decide how good it really is. Summary: it is a great piece of technology and the only tradeback is the locked down platform. I have abandoned my Palm and am not looking back.

Slowfs

I have just encountered a bug in Gnome that is much more visible when the hard drive is slow or overloaded and responds slowly. This gave me an idea - how about a simple transparent FUSE filesystem that does nothing else than delay, slow down and possibly reorder filesystem requests? Such a filesystem would be very useful for debugging. We developers tend to have high-performance systems and that hides many bugs, but if we could have a slower system on-demand, it will give us the ability to debug our applications better.
