Access point recommendations?

With some upgrade of my Internet connection, it seems that my trusty WRT-54GL wireless network is now a bottleneck. I would love to get a recommendation for 802.11ac etc access points. I'll be operating them strictly in access point bridged mode, and I'll need several so cost is a factor. But the WRT-54GLs have been spectacularly reliable and did not get confused and need reboots like many other products. That is something that I absolutely need.

More disk!

I am in Canada, and have bought once again more hard drives! C-Ordinateurs Canada, the local Fry's equivalent, supplied the goods!

If you think about IOT security, think broad enough!

Internet of Things security issues are serious, and are often the focus of discussions. The discussion is much needed. How can we make our IOT devices safe?

How can we prevent attacks similar to those that last year caused many popular Internet services to be unavailable, with badly secured IOT devices being used as a part of the attack?

This is a very important topic.

However, I would like to argue that people often think about this in a too narrow manner. First off, we  have a tendency to focus on visible, concrete things. However, there's more to IOT than the gadgets, and I think the other parts deserve equal scrutiny.

The IOT is not in the gadget, it is in the cloud.

We have to secure the gadgets, but we also have to secure the rest of the system. And more broadly, it benefits the consumers and users to have secure, interoperable, and open solutions for both the gadgets and other parts of the IOT ecosystem. We need data that is in well-specified format, we need data that is under user control, we need systems that you and I can compose from components. But we do not need closed ecosystems.

Internet and Societies

Today we have an interesting panel discussion organised by ISOC and Chatham House on the effect of the Internet on societies. Is the Internet helping bring societies together, or creating more divisions? With the increased criticism against globalisation, fake news, and the emergence of closed social circles for like minded (and often misguided) fragments of society, it is easy to be worried about this.

But, it is also easy to focus on the most visible issues. When looking at the Internet and societies, one needs to consider the full scope of human interaction, andconsider human, technical and commercial aspects together.

What issues are affecting our ability to connect together? I want to start with five points:

Human interaction is broad, and we need to look at the whole picture. It is easy to focus on the most publicly visible forms of media, and see how the news media for instance has, to put it kindly, become more diverse.

But whole picture is broader and more nuanced, and the concepts of togetherness and divisions may not be so applicable. For instance, the Internet has made it much easier for various smaller groups to connect where they perhaps had no ability to do so before. Communities working on Wikipedia, people with special interests being able to connect, minorities connecting to their culture, and so on.

Human interaction is both about tech and human abilities. It would be a mistake to think about solely technical solutions for problems involving, say news or social media.  Our technical capabilities advance at an incredible speed, but humans are also very good at learning new skills in new environments.

But, clearly critical media reading and communication skills are needed even more in today's world. These topics need to become even more central in our schools and continuing education programs.

Division vs. unification goes beyond people discussions. The Internet continues to be embedded in the fabric of our societies. We need to consider not just the people's discussions, but how well the Internet supports all the other interactions from personal gadgets to managing cities' traffic to running businesses.

Technical and commercial considerations. TCP/IP and the web provide a platform where we have almost universal interconnectivity and lack of technical barriers.

Still, as the IAB's IOT semantic interoperability workshop pointed out last year, interoperability at the level of applications can still be a problem. Can you buy Apple lightbulbs for a house that has Microsoft light switches?

And more broadly, are commonly used Internet services such as social networks erecting borders that restrict efficient connection, for instance due to their deployment patterns as is shown in the image further down?

And, is our increasingly centralised "winner takes it all" Internet economy driving a model where it becomes difficult to switch social network/search/video/mail/application store providers?

Finding broader consensus is hard, but rewarding. As those of us who work in standards or open source realise, finding agreements in broad, diverse communities is hard and time-consuming. Yet, we find the motivation to do so because if we succeed, the benefits are much greater than with everyone running their own things. We've obviously done this not just with technical developments like the Internet, but also to a large extent with our societies, building their infrastructure and rules. And I believe we will continue to be able to do that.

And where does all this leave us? Clearly, there is a lot of work ahead of us. But that work is not merely about the public sphere of news media or social media discussions, it is also about our ability to offer communications tools for all groups, regardless of their size. Our continuing education of the human parts of the system. Our drive to improve standards so that the technology allows connections. Our drive to ensure that the business system provides the possibilities for evolution and connection.

I would also like to point to my other article for a discussion of why IOT security is a much broader topic (inline with the thoughts in this article) than people usually focus on.

What do you think? Leave a comment below! You can also follow our panel discussion online.
