Summary: CRTC PN 2008-19; ISP Traffic Managment in Canada

/ Christopher Parsons / 13 Comments

As someone who is academically invested in how the ‘net is being regulated in Canada, I’ve been following the recent CRTC investigation into Internet management practices and regulation with considerable interest. Given that few people are likely to dig though the hundreds of pages that were in the first filing, I’ve summarized the responses from ISPs (save for Videotron’s submissions; I don’t read French) to a more manageable 50 pages. Enjoy!

Update: Thanks to Eric Samson and Daniel for translating Videotron’s filings – you guys rock!

Acer Aspire One Review

/ Christopher Parsons / 2 Comments

I’ve recently become responsible for the upkeep of an Aspire One netbook. My thoughts, thus far: wait for a while, get another model than I did, and dump Linpus as quick as possible. First, I’ll provide the actual specs for the netbook in the house, and then outline my thoughts a bit more.

Acer Aspireone (AOA110-1531 (Refurbished))

  • Sapphire Blue
  • Intel Atom Processor N270 (512KB L2 cache, 1.60GHz, 533MHz FSB)
  • 512BM DDR2 533 SDRAM
  • 8GB SSD
  • Card Reader
  • 802.11b/g WLAN
  • 10/100 LAN
  • Webcam
  • 8.9″ WSVGA (1024X600)
  • 3 cell battery
  • Preload with Linux

The Good

I’ll start with the good points: it’s very light, was very affordable (~$290 Cnd after taxes), and the Linpus OS boots very quickly. The screen is gorgeous, and with decent battery management you can squeeze about 2.5 hours out of it. While I’m not the biggest fan of the keyboard (I’m now very used to the ‘chicklet’ style Apple keyboards) it’s not terrible – I can probably hit about 80% of my average wpm out of it.

The Not-So-Good

Now, let’s talk about what I dislike:

  1. It’s a locked box. Seriously – I’ve broken down my share of notebooks, and while I’ll likely have another go in a week or two, actually accessing the SODIMM slots is hard. Really hard. Hard enough that I’d say either wait until they make getting into the AAO more reasonable, or just buy one with more memory. These little guys are not meant to be opened and modified (you can, but it’s not easy).
  2. Linpus is terrible. There, I said it. It boots quickly, but they’re working off a modified version of Fedora, and when I try to use the add/remove programs I consistently get dependency errors. Is this fixable? Sure. Should I have to fight with the damn OS at the command line so that I can upgrade to Open Office 3.0? No.
  3. Support from other OSes is still in the infancy stages. I’ve worked with Linux before, and I get the ‘Linux is a learning experience, and you can’t expect things to just work.’ That said: I don’t want to be fiddling around with the command line for a few days to get my install working properly. At the moment, I’m just waiting for some bugs with Ubuntu to get ironed out and then Linpus is being replaced.
  4. Linpus doesn’t connect to wireless networks. Well, let me rephrase: it will connect to non-enterprise networks. Anything WPA2-Enterprise or newer, and you’re out of luck until you replace the network manager. When you *do* replace the manager, you run into problems with it not remembering wireless access passwords when you come out of hibernation.
  5. Card reader memory allocation is hit and miss. Apparently, when you don’t tinker with anything, you can insert an SD card and that SD card is dynamically added to the available flash memory available to the OS. This is cool – I got an 8GB SD card to slide into the AAO, which would give it a cool 16GB of total internal storage – more than enough for casual browsing and word processing. The catch: as soon as you make the needed modifications to access the OS proper, you have to manually mount the SD card each time you turn on the computer, or bring it out of hibernation. While this wouldn’t be an issue if I didn’t want to unlock the OS, I don’t think that using the computer as a computer should mean that this breaks.
  6. Ships with Firefox 2.0. I mean, really – FF3.0 has been out for a long time. Why the hell is it shipping with FF2.0?
  7. Terrible SSD HDD. I get a 7.x MB write to the disk. Enough said.

If you’re looking to buy one of these, get a version with a spinning disk drive. That said, if you want a netbook that is just going to rock out of the box, I’d suggesting getting the HP 2140 – it’ll be a bit more expensive, but I think you’ll be a lot happier. Maybe I’ll change my tune once Ubuntu is loaded on the netbook. In fairness, I should note that I’m being picky (because it’s what I do with these kinds of things), and the person actually using the computer doesn’t have these complaints – it does what it needs to (though not being able to access WPA2-Enterprise has caused them problems). This said, I think that items (1), (2), (4), (5), (6) and (7) really are showstoppers, though (2) and (4) will both be alleviated by changing OSes, (5) is resolvable by shifting where documents and such are saved to, and (6) is solved by hitting up the command line a bit.

My rating: 3/5

Review: Privacy On The Line

/ Christopher Parsons

This updated edition of Diffie and Landau’s text is a must-have for anyone who is interested in how encryption and communicative privacy politics have developed in the US over the past century or so. Privacy On The Line moves beyond a ‘who did what’ in politics, instead seeing the authors bring their considerable expertise in cryptography to bear in order to give the reader a strong understanding of the actual methods of securing digital transactions. After reading this text, the reader will have a good grasp on what types of encryption methods have been used though history, and strong understandings of the value and distinction between digital security and digital privacy, as well as an understanding of why and how data communications are tracked.

The only disappointment is the relative lack of examination of how the US has operated internationally – there is very little mention of the OECD, nor of European data protection, to say nothing of APEC. While the authors do talk about the role of encryption in the context of export control, I was a bit disappointed at just how little they talked about the perceptions of American efforts abroad – while this might have extended slightly beyond the American-centric lens of the book, it would have added depth of analysis (though perhaps at the expense of making the book too long for traditional publication). One of the great elements of this book is an absolutely stunning bibliography, references, and glossary – 106 pages of useful reference material ‘fleshes out’ the already excellent analysis of encryption in the US.

Ultimately, if you are interested in American spy politics, or in encryption in contemporary times, or in how these two intersect in the American political arena, then this text is for you.

Update: Mobiles and Your Identity

/ Christopher Parsons

Last year I authored a post entitled “Mobiles and Your Identity“, where I attempted to unpack some of the privacy and surveillance concerns that are associated with smart phones, such as RIM’s Blackberry and Apple’s iPhone. In particular, I focused on the dangers that were associated with the theft of a mobile device – vast swathes of both your own personal data, as well as the personal information of your colleagues and friends, can be put at risk by failing to protect your device with passwords, kill switches, and so forth.

Mark Nestmann, over at “Preserving Your Privacy and More” has a couple posts discussing the risks that smart phones pose if a government authority arrests you (in the US). He notes that, in a recent case in Kansas, police examined a suspect’s mobile phone data to collect call records. When the case was brought to the Supreme Court, the Court found that since the smart phone’s records were held in a ‘container’ (i.e. the phone itself) that the police were within their rights to search the phone records. Mark notes that this ruling does not apply to all US states – several have more sensitive privacy laws – but leaves us with the warning that because laws of analogue search are being applied to digital devices that it is best to limit the data stored on smart phones (and mobile digital devices in general).

P2P and Complicity in Filesharing

/ Christopher Parsons

I think about peer to peer (P2P) filesharing on a reasonably regular basis, for a variety of reasons (digital surveillance, copyright analysis and infringement, legal cases, value in efficiently mobilizing data, etc.). Something that always nags at me is the defense that P2P websites offer when they are sued by groups like the Recording Industry Association of America (RIAA). The defense goes something like this:

“We, the torrent website, are just an search engine. We don’t actually host the infringing files, we are just responsible for directing people to them. We’re no more guilty of copyright infringement than Google, Yahoo!, or Microsoft are.”

Let’s set aside the fact that Google has been sued for infringing on copyright on the basis that it scrapes information from other websites, and instead turn our attention to the difference between what are termed ‘public’ and ‘private’ trackers. ‘Public’ trackers are available to anyone with a web connection and a torrent program. These sites do not require users to upload a certain amount of data to access the website – they are public, insofar as there are few/no requirements placed on users to access the torrent search engine and associated index. Registration is rarely required. Good examples at thepiratebay.org, and mininova.org. ‘Private’ trackers require users to sign up and log into the website before they can access the search engine and associated index of .torrent files. Moreover, private trackers usually require users to maintain a particular sharing ration – they must upload a certain amount of data that equals or exceeds the amount of data that they download. Failure to maintain the correct share ratio results in users being kicked off the site – they can no longer log into it and access the engine and index.

Review: Access Denied

/ Christopher Parsons

The OpenNet Initiative’s (ONI) mission is to “identify and document Internet filtering and surveillance, and to promote and inform wider public dialogs about such practices.” Access Denied: The Practice and Policy of Global Internet Filtering is one of their texts that effectively draws together years of their research, and presents it in an accessible and useful manner for researchers, activists, and individuals who are simply interested in how the Internet is shaped by state governments.

The text is separated into two broad parts – the first is a series of essays that situate the data that has been collected into a quickly accessible framework. The authors of each essay manage to retain a reasonable level of technical acumen, even when presenting their findings and the techniques of filtering to a presumably non-technical audience. It should be noted that the data collected includes up to 2007 – if you’re reading the text in the hopes that the authors are going to directly address filtering technologies that have recently been in the new, such as Deep Packet Inspection, you’re going to be a disappointed (though they do allude to Deep Packet technologies, without explicitly focusing on it, in a few areas). Throughout the text there are references to human rights and, while I’m personally a proponent of them, I wish that the authors had endeavored to lay out some more of the complexities of human rights discourse – while they don’t present these rights as unproblematic, I felt that more depth would have been rewarding both for their analysis, and for the benefit of the reader. This having been said, I can’t begrudge the authors of the essays for drawing on human rights at various points in their respective pieces – doing so fits perfectly within ONI’s mandate, and their arguments surrounding the use of human rights are sound.
