Released: Literature Review of Deep Packet Inspection

/ Christopher Parsons

Scholars and civil advocates will be meeting next month in Toronto at the Cyber-surveillance in Everyday Life workshop. Participants will critically interrogate the surveillance infrastructures pervading daily life as well as share experiences, challenges, and strategies meant to to rein in overzealous surveillance processes that damage public and private life. My contribution to the workshop comes in the form of a modest overview of literature examining Deep Packet Inspection. Below is an abstract, as well as a link to a .pdf version on the review.

Abstract

Deep packet inspection is a networking technology that facilitates intense scrutiny of data, in real-time, as key chokepoints on the Internet. Governments, civil rights activists, technologists, lawyers, and private business have all demonstrated interest in the technology, though they often disagree about what constitutes legitimate uses. This literature review takes up the most prominent scholarly analyses of the technology. Given Canada’s arguably leading role in regulating the technology, many of its regulator’s key documents and evidentiary articles are also included. The press has been heatedly interested in the technology, and so round out the literature review alongside civil rights advocates, technology vendors, and counsel analyses.

Review: Apple iPad

/ Christopher Parsons

I pre-ordered the iPad  as soon as I could and unpacked it the day that I returned from a trip to South America (that saw me miss its actual delivery). I’ve had the device for over a month now, have been actively using it, and wanted to offer my impressions. Those impressions, I will note, are significantly conditioned by the reasons that I bought the device, which I’ll outline. I’ll first briefly address the actual hardware and operating system of the device, then move to what I like and dislike about the product. Ultimately, I’m happy with the device and have absolutely no regrets in getting this particular first-gen Apple product.

The screen, ergonomics, and weight are all fine. It’s using an IPS-LCD, which means that viewing angles are good and colour reproduction is pretty faithful. While some have criticized the back for being slightly rounded, it hasn’t bothered me in any way, nor has the weight of 1.5lbs struck me as ‘heavy’ though the device is heavier than appearances might lead one to believe. There is a bezel surrounding the screen itself and it makes sense: I can rest my hands on the non-interactive bezel without affecting whatever I’m displaying on the screen. This is a good thing. the iPad has the same touch interface as the iPhone and iPod Touch. This makes the iPad simple to use, if lacking any deviant features from those earlier devices (and, with the release of iOS 4, the iPad actually has slightly fewer features than the iPhone or Touch). In light of its use of the older 3.2 release of the OS, the iPad is horrible if you rely on multiple windows being open to get work done and is a poor choice for any content producer looking to do a lot of work on it that will see you flipping between a document/content production editor and the web. In effect, anyone who’s tried doing intensive content production on the iPhone or Touch will largely encounter the same old problems here. I’m not saying that you can’t do such production, but it’s far less convenient than on a full desktop/notebook or even netbook. On the upside: the device is light and battery life is good (I tend to go for 36-72 hours without needing to plug in, with moderate to heavy use each day).

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 of “National Identities and Communications Technologies” by Mark Poster

/ Christopher Parsons

In this article Poster examines the process of globalization through the lens of culture. He is specifically interested in examining how cultural globalization and digital mediums intersect with the nation-state’s competencies.

Decentralized networks have existed in some fashion or another for decades, but the Internet is more developed than the telephone or any other analogue system because it avoids circuit-switched technologies and private ownership. Whereas the telephone was limited in the number of people that could be simultaneously broadcast to, the Internet is designed for mass communication and is insensitive to the loss of particular nodes. As a facet of the digital environment all information on the ‘net has the advantage “virtually costless copying, storing, editing, and distribution” (235).

A central element of Poster’s argument is his distinction between analogue and digital cultural artifacts – analogue artifacts exist in a particular jurisdiction and, as a result of being material constructs, are inherently challenging to duplicate. In contrast, digital artifacts are inherently designed to be shared. Digitized items’ duplicability causes them to escape the laws that traditionally protect cultural items – culture is currently undergoing a shift from the status of being precious, rare, and protected to the status of being precious, common, and naturally unprotected by their digital form. Moreover, the ease of transferring digital cultural items across jurisdictions limits the nation-state’s ability to stem the flow of culture, subsequently preventing the nation-state from developing a localized national culture. Poster notes that on the Internet,
