Internet adoption rates have they exceeded that of earlier mass communication techno­logies

July 23rd, 2008

I must admit I had always had this nugget in my mind that Internet adoption rates exceeded those of earlier mass communication techno­logies (radio, tv), but I may just be clinging to one of those cybertruths.
According to Gisle Hannemyr and his report ‘A Critical Examination of Adoption Rates‘ there appear to be no major differences between the adoption rate of the Internet and the patterns of adoption for radio and tv in the past.
Through the report he has

identified the discrepancy in adoption rates as possibly resulting from trans­lations of actual data into carefully phrased re-statements of fact in support of a particular financial or political agenda.

Funny that!

DNS unstuck

July 14th, 2008

There has been a serious flaw identified in DNS recently, which may allow an attacker to target an ISP, replacing the entire web with their own content, not good!

More can be seen from Dan Kaminsky Discovers Fundamental Issue In DNS: Massive Multivendor Patch Released .
To save the day we also have the newly created Industry Consortium for the Advancement of Security on the Internet (ICASI), which offer advisories and support.
All of which still has me very worried given that on Wednesday, 3rd December 2008 the .tel TLD will offer a service that allows individuals and businesses to store and manage all their contact information and keywords directly within the Domain Name System (DNS) without the need to build, host or manage a website.
And what about SocialDNS, personal details already retrieved via DNS. go://miguelpdl [Just a Firefox plugin required].

Papers from the Google vault

July 6th, 2008

In reviewing some articles for that last post I came across two other interesting areas which are worth a mention.
A list of recently published papers from Google
http://research.google.com/pubs/papers.html
And here is just a great paper on the “Cold Topics in Networking
J. Crowcroft, Cold topics in Networking, ACM SIGCOMM Computer Communication Review, Volume 38 , Issue 1, January 2008.
One last item which I didn’t get to use this time was the new “PDF Widget on Acrobat.com“. I had the same concern as the commenter, as I don’t own the pdf I didn’t feel comfortable uploading it to the Acrobat site. But I will try this on some of my own pdfs next time.

Scientific papers and journals in the future

June 24th, 2008

So are Are Academic Journals Obsolete?
My last post highlights the question and here are some varying opinions
1) Interweb based debate, this Slashdot article appears to go along the lines of yes they’re needed as it a mechanism for “Peer review with Quality in mind”
2) Paper based debate, this paper by Bora Zivkovic provides a very interest prediction for research papers

scientific paper of the future will be a work in progress — with different people with different skills and talents contributing to a body of work sequentially: one has the idea, another turns it into a hypothesis, another designs the experiments, another runs them, another analyzes the data, another visualizes them, another interprets them, another places several such pieces of work together into a historical and philosophical context and finishes writing the “paper”.

B. Zivkovic, The future of the scientific paper, Journal of Science Communication, Volume 07, Issue 02, June 2008, http://jcom.sissa.it/archive/07/02/Jcom0702%282008%29C02/Jcom0702(2008)C02.pdf
So this makes me wonder will Open Access Journals be some way to fulfil this prediction? I’ve seen an example of SRE before, here’s another one PLoS One.
Although in both cases the Computer Science papers submissions are quite low
http://www.plosone.org/article/browse.action?catName=Computer+Science
as compared to the other sciences.
But in some ways will we just skip this and just pander to the YouTube generation for example

Research behind what really is behind the Diet Coke and Mentos physical reaction?

June 12th, 2008

Just picked up this interesting item from the NewScientist on the Science of Mentos-Diet Coke explosions explained which has taken its cue from the American Journal of Physics paper “Diet Coke and Mentos: What is really behind this physical reaction?”
According to the author, its not totally down to the chemical reaction of the ingredients in the sweets, and the ingredients in the Coke, its also got to do with microscopic dimply surfaces of the Mentos which disrupts the attractions between water molecules hence encouraging bubble cascading.

But didn’t the guys from MythBusters already solve this one?
http://www.youtube.com/watch?v=kMXPOqovSBs [1]
Well one explanation may be that research papers do not get published at Internet speed! The paper was received 7 June 2007; accepted 5 February 2008, published June 2008. The MythBusters show aired on August 9, 2006 ……… hmmmm hang on a second that doesn’t quite match up, but I see back in the comments field for this article the author is defending their work.
The paper looks at items:-

such as the importance of the speed with which the samples fall through the soda and the soda temperature. I also rigorously quantify the effects of surface roughness of the samples and the changing surface tension of the liquids, using nanoscale microscopes and contact angle measurements. I credit the Mythbusters in the paper for identifying the primary ingredients (and I love their show), but they did not really go into the WHY behind the reaction as much as I do in the paper.

Mores the point who would have thought a PhD dissertation on “Nanotribology Fundamentals: Predicting the viscous coefficient of friction” would lead to explaining this.
I’m a believer that the devil is in the detail.
Einstein in one of his early papers answered the simple question : How can you measure sugar molecules dissolved in a cup of tea? His formula for measuring the size of sugar molecules in a liquid was applicable to all molecules and provided much of the framework essential to his analysis of Brownian motion [pdf].
Okay okay I’ll finish .. it’s still interest though.

IPv6 being pushed into the limelight

June 5th, 2008

I know I’ve mentioned this maybe one too many times … but it now appears that the only sustainable solution to deliver expected economic and social opportunities for the future of the Internet economy is the deployment of IPv6.
So says an OECD Report on the Economic considerations in the Management of IPv4 and in the Deployment of IPv6 [pdf].
Pigeon Point Lighthouse on Flickr by MumbleyJoe [1]
I wonder will this report on IPv6 and the recent EC supported EUROPEAN IPv6 DAY – 30 May 2008 see IPv6 safely come home to port, or may leave it still be left out to sea in the ocean of undeployment?
It looks like Europe has an Action Plan …. do you?

Edutainment Desktop and the OLPC

May 22nd, 2008

Some times I bring work home with me ……. but when I finish reading those emails, the laptop gets left on the kitchen table for a little while and Kate becomes curious …..

what does the puter do daddy?

With it being a Tablet PC we have found some great online colouring sites, with the Crayola Digi-Color head and shoulders above the rest. The use of the ‘electronic’ pen is great for Kate as she doesn’t get messy at all !
After numerous times running this and a couple of related colouring websites I got more interest (while my daughter got more bored) in finding other sites or even running her own desktop …. but what should I go with?
Well to start with this GPL Edutainment Software article on Slashdot was very timely, and I found it handy. But in running these I wanted a more tightly closed desktop environment.
Then the One Laptop per Child [OLPC] (or $100 Laptop) project appeared on the radar and its Sugar GUI. Well really there isn’t anything else out there (well I know there’s Edubuntu but its not suitable for the age group). I was really curious because there seemed to be tons of activities specially tailored for kids as part of the GUI and so I got a great LiveCD called LiveBackup XO-LiveCD to check it out for myself (and for Kate of course).
Sugar GUI
And sure enough on an old Compaq Presario the LiveCD boots just fine (no networking though) and we can have a look at a number of the Sugar Activities like Turtle Art, Paint(Oficina), TamTam amongst others.
They were good ………. but the overall GUI was for me confusing (Kate didn’t seem to mind so much), especially the ‘STOP’ symbol for closing programs instead of an ‘X’ button or symbol. Now I know the whole environment has a different design philosophy, but it’s just that it doesn’t translate to anything out there, and I’m not so sure its such a good idea !
Anyway since our little experiment there’s been loads of news from the OPLC camp, $100 laptop’ embraces Windows XP, ‘$100 laptop’ platform moves on and finally I find myself back at Slashdot looking at A View From Inside the OLPC Project. This all points to some very interesting times for the OPLC, and for the moment I’ve not re-run the Sugar GUI in a couple of weeks, the original colouring websites will keep us busy for the time being.

Calculating Carbon footprint from Travel

April 27th, 2008

Thanks Eamonn for picking up my question on the calculation of my carbon footprint from recent trips, I’ve had a look at the Dopplr solution in association with AMEE and it is exactly what I was looking for.

The movers and shakers on this months Programming Community Index

April 27th, 2008

A the joys of programming, there are so many to choose from and my interest in a recent Slashdot article on the TIOBE Programming Community Index was raised due to a couple of small “home” projects I’ve recently managed to complete. Firstly the movers and shakers on this months Programming Community Index list were
1. Java
2. C
3. (Visual) Basic
4. PHP
5. C++
6. Perl
7. Python
8. C#
9. Ruby
10.Delphi
For me there are certainly a couple of surprises in there, but for now I have some comments on the Perl / Python tussle.
python-v-perl.GIF
So my home project was a “script” to read out (using a ‘text-to-speech’ program) a Quote of the Day from a RSS feed.
I’ve had this QOTD feed on my feedreader account for years but never seem to get a chance to read them, now I just have them read out for me once a day.
Having completed the project in Python [9 lines of code and an imported library feedparser] I wondered why does Python exist? Shouldn’t Perl do the job perfectly fine?
Many suggestions are offered, such as Pythons readability and extensibility, or the fact that Python offers much faster application development, and for me I wanted to see if this was true ……. and my experience is born true by this article from the Linux Journal on Why Python? by Eric Raymond [May, 2000] although my disclaimer is that if you manage to read the comments I’m a 3).
Finally back to the ‘Quote of the Day’, as a network programmer I should have been thinking about doing this project with the Quote Of The Day (QOTD) protocol, utilising a service provider like http://quotes4all.net/ but then I’m not so sure Python would have come up on my radar, if I had started out like this.

I’s to the Future

April 5th, 2008

It’s massive and ICT 2008 comes to Lyon on November 25-27th 2008 ….. book your hotel now!
There are three main parts to this event, the speaker/panel based conference, the exhibtion and the networking session, and its important to make an impact on all three.
For the moment there are two main deadlines to consider
1) Call for exhibitors
2) Call for networking proposals
As for past events in 2004 the host city for IST 2004 was Den Hague with the overall theme of “Participate in your future”. We certainly did this as this is where our first in-roads on the Living Labs approach was made public …. with the help of our partners from CDT Lulea.

With a theme of ‘Strategies for Leadership’, we took a big lead with Jim & Zeta hosting a very influencial Security Networking session
So here’s to looking forward to ICT 2008.
