I guess this is a kind of "different" blog for me. A friend of mine has his own blog at blog.menneske.org. He is writing a small series on chocolate right now, and I found his entries kind of interesting and educational.

The future, 2.0
As a follow up to my earlier fantasy of new possibilities regarding a documented generation I would like to blow out some steam regarding social software as well.
One of the problems we see today is that there are only a few people producing the information that is consumed by all the rest. Those reading are participating with tagging, bookmarking and rating of the content, but even this should be easier. The production of the content could also be easier. So let us play with the idea of a documented world. On our way forward we have a few stops on the way. Some of them we are experiencing right now, among else by using Facebook, Linked-In, Plaxo or other social networking applications. By blogging and micro-blogging what we do and what interests us we are giving the world knowledge and information that can be used by other applications as what we often call value-added content. Consider this, you are watching a video or listening to a podcast on the net regarding some information. The video or audio is tagged in such a way that as you play the content, different meta-information rolls by in tandem with the content, and the media player might then display related information based on automated searches as you watch. We are talking hypermedia that intelligently can give you information that you need or want. You will be able to decide where the information is gathered from. In the next generation of social software I expect us to be able to increase the value for each other in even better and easier ways than today. And as always, the enabler of these features will always be technology. So in the future, expect great things. Probably not some of the small ideas I present to you here. What we will see will probably be better. And you will be a part of it. By easily producing content, and adding meta-information and grading what you see. The world will give you more of what you want and of what interests you. Whether it is semantic technology or intelligent search engines, I bid welcome to interesting and feature rich social networks, in a documented world where you can have an even more enhanced life experience. Soon, in a life near you! Tuesday, June 3. 2008

Wish for 2008 Posted by Jon Leirdal

Wish for 2008When you read the news from anti-virus companies and security advisors you get convinced that 90% of the software you find on the net is malware, and the last 10% have so many security issues that it turns out the same thing. At the same time a life seems to be worth less than the copyright interests of media companies. I don’t know if you have noticed, but I feel that the whole world has been overrun by solutions and programs that want to harvest personal information about me. The products that don’t ask for the information grab it anyway. Trusted computing is a much debated architecture, maybe rightfully so. That kind of architecture might limit the spreading of free/open source software. Microsoft has proven that they can offer this trough their HD-Video support. There they have signed code in all layers, and only approved hardware devices are allowed in the pipe from storage media to screen. I am not saying that it is impossible to bypass this pipe in some way, but the threshold to perform such a hack has been raised a fair bit. So, when you consider the stack of components needed to display HD-Video, what do you need to have the same security/quality for our computers? Especially when you are connected to the Internet? The question then is if we maybe should take a look at this “cursed” subject again. Financing solutions in order to secure that open source software can be verified and approved might become a reality. There is one thing that we have learned so far. It is impossible to count all evil. You cannot permit the execution of all software except the bad ones listed in a list. Such a list will never be complete. But you can allow all enumerated good software and block the execution of all other code. Anti-virus software tries to perform this enumeration on our behalf, but still they do not know everything and ask the users what to do when in doubt. When they do, the s**t hits the fan. Users do not know what to do. They do not realize the consequences of their choices. Again, the driver is the money. It is somewhat of a symptom of the state of the world that it’s more important for Microsoft that a video is not copied than to secure the personal information of a user. If somebody steals all our personal details, all our money from our bank accounts and our identity, that is not as important for Microsoft as a video unlawfully duplicated and distributed. So what is my wish for 2008? My wish is that our lives and our identities will become more important to protect on the net than the economic interests of a few.

Comments (0) Trackbacks (0) Bruce Schneier: Security in ten yearsBruce Schneier have this little gem available on his site today. Bruce and Marcus Ranum are discussing security issues and trying to guess where the field will be in ten years time. I've got to say that they are painting a somewhat bleak picture, and I sincerely hope that they are wrong in some of their assumptions, but I fear that they are probably correct. Tuesday, December 4. 2007Life in NorwayNow, as a lot of you might know. People in Norway like to complain a bit, even though we frequently appear among the top 10 when it comes to the best countries in the world. Well I thought you might want to confirm your suspicions that Norway is an expensive country. ECA international has compiled it's annual "Top 10 expensive cities" report. Norway have two cities on the list, second and fourth place. Yeah, way to go Norway! Tuesday, November 27. 2007A walk in the lightThursday, November 15. 2007
Code breaking challenge, 1945 vs 2007 Posted by Jon Leirdal

Comments (0) Trackbacks (0) Code breaking challenge, 1945 vs 2007According to BBC for the first time in more than 60 years a Colossus computer will be cracking codes at Bletchley Park. For all of you that don't know. Bletchley Park was the site that Alan Turing and other brilliant men worked when they cracked, among else, the German Enigma codes during World War II. Another reason I find this particularly interesting is that I recently finished the novel "Cryptonomicon" by Neal Stephenson. Some of the story in that book takes place at Bletchley Park and deals among else with that wartime effort. So, when "participants" from that book resurfaces as a rebuild and is matched up against at modern computer in a code cracking challenge, I find it quite intriguing. Update: 2007-11-19 The colossus lost the challenge. Well probably not too unexpected. It is after all a machine built in 1943. There are a few generations between that machine and a modern day PC. Read more here Tuesday, November 13. 2007Strike in Hollywood... why?We have probably all heard of the writers strike in Hollywood. I never really cared that much about it, but then I read this article: Kung Fu Monkey: The Albatross and then I changed my mind. I do care. Read it for yourself. Friday, November 9. 2007

Comments (0) Trackbacks (0) The 10 Most Puzzling Ancient Artifacts. Really??Pretty sensational isn't it? If you check out the article The 10 Most Puzzling Ancient Artifacts or an alternative version here, it seems a bit too god to be true. I am probably quite gullible, but not when it comes to articles like this. If you do a quick search on Wikipedia several of these gets debunked instantly.
This list has been debunked several times before I see. Oh well. Now it has been done once more. Wonder why they forgot this little nugget, the helicopter hieroglyph. Saturday, November 3. 2007Autumn colors
