Conroy backflips

Loose thoughts by Bjorn Landfeldt

Finally it seems, has senator Conroy realised the political incorrectness of his mandatory filtering mantra.

Yesterday, senator Conroy stated in a senates estimate committee that Internet filtering wold remain voluntary in Australia. This is in stark contrast to his former stance where he has diligently been telling the entire ISP industry to keep quiet and stop questioning his authority.
Telecom TV reported over night but funnily enough there is nothing in Australian media as yet.

Lets hope that Xenophon remains sensible about the issue.

However, Labour has not given up on their plans altogether, Conroy states that if there would be majority in the senate, they would push legislation through. Let's hope there is time at least to gain some knowledge and more insight into the entire matter so that sensible decisions can be made if that time would to come.

Confusing

Loose thoughts by Bjorn Landfeldt

I noticed today that NICTA (a research institute here in Australia) uses some interesting terminology to specify how its research should be categorised. NICTA is following a model proposed by Donald Stokes where the term used is 'used-inspired basic research'. The analogy is 4 quadrants where in one dimension there is scientific advancement and in the other application or usefulness. The 4 quadranta then have a yes or no along the two columns or rows. In one quadrant there is yes-advancing knowledge and no-no practical application called the Bohr quadrant, in another there is no, does not advance knowledge and yes-practical application called the Edison quadrant. In the third useful quadrant (the no,no is not particularly interesting but can often be seen in grant applications) we find Louis Pasteur who made foundational contributions as well as gave us nice and bacteria free milk. The Pasteur quadrant represents the 'use-inspired basic research', fair enough.

However, stumbling across the NICTA entry on wikipedia, I find that the organisation is muddying the waters a bit. They talk about 'pure basic research' and 'pure applied research' as well. OK so now we have what the rest of the world uses, 'pure, basic or foundational research' and 'applied research' as well as the Stokes' 'use-inspired pure research' as well as the NICTA 'pure basic research' and 'pure applied research'. I believe seeking to prove that it is possible to prove P=NP if indeed it holds true should be regarded as 'applied basic pure research' because it is useful to know that a proof can be found if indeed it holds true that it is so and that is applied, but the proof itself (if it indeed is true) is to be regarded as F***ing pure basic for most people.

It should also be made known that proving that it is possible to construct a pair of shoes that will not wear out for at least 10.000 km of normal walk so that it is possible to investigate the effects on human psyche having to walk for that long, should be regarded as 'pure applied use-inspired basic research'.

Now back to that 'no,no' grant application..

Public lecure video

Loose thoughts by Bjorn Landfeldt

Last Friday I gave a public seminar on the proposed filtering of the Internet by the Australian government. A video of the talk is now available on the school of IT web site. The current version is mp4 encoded, flash video will come later.

Update, an embedded flash version is now available here.

Interesting NBN news

Loose thoughts by Bjorn Landfeldt

The government should be congratulated on the courageous plan to build a government/industry funded broadband network as announced earlier today. Coming from outside Australia and seeing the close to monopoly position Telstra currently have one may wonder why this has not happened before. Perhaps now we can get SIP pops and IPTV plus video on demand like civilised countries. This will inevitably open up opportunities for innovation and service roll out in Australia. If the government combine the one laptop per child, NBN and a building policy that each home should have at least one networked computer as minimum standard as is the case in countries such as Sweden, perhaps Australia will be able to embrace this crazy thing called the Internet and start to take advantage of its enabling powers and information distribution capabilities.

One worry though; if the government owns the national backbone, wouldn't that be the perfect place for content filters? This way the government fully control the Internet and will not have to deal with irritating and questioning ISPs. THey don't even need to tell the general public they are doing it, shhhhhhh.

Public lecture

Loose thoughts by Bjorn Landfeldt

I will be giving a public lecture next Friday April 3, on the topic of the Australian Internet content filtering affair. The point is to provide an academic researchers view on the matter and to highlight some fundamental issues that makes it difficult to implement the proposed scheme, all welcome.

The lecture will be held at University of Sydney, the Peter Nicoll Russel (PNR) building in the Engineering precinct, 4-5 pm.

Councils getting rid of scuba diving in Sydney

Loose thoughts by Bjorn Landfeldt

One aspect of scuba diving is that you carry heavy equipment around, and it is important to be able to get close to the entry/exit point when changing and putting the gear on. Another important issue is to have safe entry/exit, shielded from waves and swell.

Pat Morin just forwarded an email by Michael McFadyen about Randwick council wanting to change parking conditions at Bare Island, so that the number of spaces is kept constant but the ones close to the island are removed or largely removed. For scuba divers this is of course an absolute disaster. Bare Island is the most popular Sydney dive site because diving is really good and there is convenient parking close to the dive sites. Already, divers cannot use Clovelly pool at Shark point for much of the year and getting out at the point is close to deadly (forcing people to try can really cause accidents). The parking at North Bondi was removed last year so that can't be dived anymore.

Why can't councils see that scuba is a recreation that has real advantage for the environment (divers care and help cleaning up etc.) and a great way to get eco tourism into the council, selling coffees, sustaining scuba shops etc. I don't think it wouldbe very costly to put in small wave breakers here and there and create good entry/exit points for us to enable access and minimise accidents. Look at Voodoo (shore version) for example. A small breaker running out 10-15 m with steps down could make that a premier dive site in Sydney at low cost. Let's lobby to make it happen.

Second black list made available

Loose thoughts by Bjorn Landfeldt

Wikileaks made a second list available on the 20th of March. The second list is a cleaned up version of the first list that now contains some 1170 entries.

Since the government threatened to prosecute any Australian involved in leaking the list, Wikileaks responded by threatening the Australian government with legal action since the action is firmly protected by Swedish law and Wikileaks operates within that jurisdiction. Interesting, is there an international diplomatic conflict about to happen as well over this? Perhaps I (as a Swede and Aussie) will have to chose sides, and which army to join after all :).

It is extremely stupid to distribute a list in cleartext in the first place. I have no idea who at ACMA decided to hand out clear text ASCII files with all the banned sites but it was not a struck of genius to do so. Why did ACMA not simply hash the sites and distributed a file with hashed values? Any filter implementation can still hash each destination URL and compare with the list without the destination address ever being exposed. It is true that there would still be people within the ACMA who would have acces to the original clear text list but the risk of spreading of the list would be much lower.

Wikileaks apparently also published a simple way of extracting the list from a down loadable software package from the netalert scheme era. Apparently, it is possible to extract a file with the conspicuous name "Websites_ACMA.txt". Well designed security software!! I wonder if the developers had dumbed down 3-year Australian university degrees......
