During last summer I purchased a set of Sennheiser HD595’s - a great product for Audiophiles. I have to say for someone who constantly listens to a lot of music - good headphones like these are a must. They are expensive for sure, but Sennheiser do seem to have a great durability and solid build quality. This is my first set of such high quality headphones, so bear that in mind - I can’t speak for other manufacturers in this space.

I purchased the iPhone 4 shortly after its release in Summer 2010. I have obviously been so quick to review this device, the iPhone 5 is upon us! My philosophy for reviewing items is you have to live with them. Well boy have I lived with my iPhone 4! As I write this on it, I do marvel at how good the hardware is. I’ve dropped this extremely expensive device on occasions too numerous to count, so luckily it is designed well.

A multitude of websites have been reporting the impending doom of ipv4 exhaustion, which is going to happen soon. All the top level address’ will be gone, but the regional registries will still have stocks of address’ in to 2011. As a user of ipv6, I thought I could share sone thoughts/insights on the events ahead…

Below is a very good video which one of my favourite tech shows, Hak5 made with an IPv6 Consultant, Joe Klein.

I wrote this script recently for a friend in a job who needed to output a certain percentage of a log file, but no more and no less. This was in Linux using bash, so I had a go at writing a solution, which you see below. Posting this up in case it’s useful to anyone else!

 # !/bin/sh # Public Domain, by Neil Grogan 2010 # Script
to output last 30% of file by lines

    OLDFILE="oldlog.txt"
    NEWFILE="newlog.txt"
    PERCENT=0.7

    #Use wc to count lines
    LINES=$(wc -l $OLDFILE | awk '{ print $1}')

    #Linespercent = 2 decimal places, lines by percent, round to whole
    LINESPERCENT=$(echo "scale=2; $LINES*$PERCENT" | bc | xargs printf "%1.0f" )

    # Use tail to get last 30% and output, can use tail -s with sleep time to have it run on sched.
    tail -n $LINESPERCENT $OLDFILE >> $NEWFILE

Let me explain both of these! I have been searching for a good blogging engine ever since I have started blogging. I have yet to find the perfect one :) Some have come close in completeness (WordPress) or price and ease of use (blogger), but none has been all-encompassing. I messed around with a blogging engine called Jekyll about a year and a half ago, but I never ended up deploying it. I had my website most recently on Google Sites, and the ease of use was pretty good, but themes-wise it was pretty frustrating, also they force an ugly footer on all pages, yuck.

Below I present some very useful extensions I use while using Google Chrome, in no particular order.

Adblock

• Blocks ads just like Firefox extension and makes the web less junky to look at. You can whitelist good ads, and an argument could be had your harming websites revenue stream, but a lot of nasty tricks such as spyware, malware have used ads as a vector to spread. Not least the dishonesty some sites use in splitting up articles in to 10 pages to pump ad revenue.

Below is my first attempt at video blogging. If I get used to it it may be easier to explain my point of view or give reviews! I have liked hiding behind words up until this point, so this is a new venture with my iPhone 4.

Since Apple released an iPad there have been various competitors announced, so it got me thinking what would it take for me to buy one? I haven’t bought the first generation iPad because the lack of a camera on a device so obviously good for fullscreen video calls has baffled me. I guess they have to store up some ideas since they need a new hardware iteration every year, Apple’s revenue model depends on that vital hardware refresh cycle.

So I was listening to some music, thinking about the announcement today on Anglo Irish Bank that we have 32% national debt and my generation will be expected to pay that. Kind of depressing if you ask me, but no one does, ’cause the media has got that one all wrapped up. So I asked myself, is their anything new we can learn, while I was listening to the Prodigy classic� Breathe. So I came to the realisation there can’t be anything added, or can there?

It’s been over a week since I received my Garmin Zumo 660 Motorcycle GPS unit. I thought I’d give it a run-down for potential buyers on my experience for the first week. Firstly I should mention, I’ve never owned another Garmin unit, and had two mobile GPS’ units before (one being Nokia N800 with Bluetooth external GPS and other Apple iPhone 3G). The reason I bring this up is that a lot of the reviews I’ve seen written compare it to it’s predecessor, Zumo 550, which obviously I can’t do.
