FastTrack Weekend Muddiest Point
I'm a little confused about what week this is now lining up with, so I'm just going to put it out there:
Are there quantifiable national or international standards that define the differences between a LAN, WAN, MAN, CAN, etc.? It seems to me that some of these network types can also be other types (i.e. - CAN can also be a LAN) but not always and the distinctions seem somewhat arbitrary.

Andrew K. Pace - Dismantling Integrated Library Systems
This article made a very interesting point that I hadn't really considered - the idea that the development of integrated library systems had plateaued in the 1990s. It's so difficult to imagine libraries functioning without integrated library systems, yet the truth of the matter is that many of these critical ILSs haven't managed to keep up with the rapidly changing needs of all libraries (especially large ones) and the functionality potential provided through the web. In my personal opinion, not all the potential functionality of the web is necessarily useful for a library end user. I think careful and well-planned advancement and integration of web functionality can make a huge difference in how patrons access information, but advancement for advancement's sake isn't productive. The library where I work recently added WorldCat Local's catalog search interface to our website. The new interface provides many useful features but also contains a number of completely superfluous ones that really have little practical use in any library setting. The new functionality of this interface wasn't so groundbreaking as to warrant the costs and the hassle of implementing it in place of our functional 'old' catalog system.
Considering the broad swath of smaller libraries with limited funding, access to any ILS is critical in promoting access to their collections. Many public and academic libraries are already organized into consortia to help collectively bargain with ILS companies to provide the best deal for their constituent organizations. In an ideal world, ILS companies could provide individualized support to institutions with needs outside the ability of the ILS to handle. Unfortunately, the cost and technical requirements needed for the frequent upgrades even to the basic ILS services often prove difficult for smaller institutions to keep up. While open source systems seem like an attractive option for cost and customization reasons, the reality is that many libraries (again, smaller ones) generally lack the technical resources (namely, individuals with programming skills) to develop such an ILS effectively. Proprietary ILSs seem to be the only option for smaller institutions who, without them, would otherwise lose access to their entire collection.
Jeff Tyson - How Stuff Works - Internet Infrastructure
A very good article - especially helpful was the overview of DNS servers, about which I had almost no knowledge. Considering how central the Internet is to the access of library resources now, this is great information to have entering the profession. To be sure, it's information that many people take for granted and simply don't think much about because of how ubiquitous the system itself has become. In my work experience on a college network, understanding how IP addresses work (and especially the changes between IPv4 and IPv6) has been critical. This article served to reinforce much of that knowledge and to actually introduce some new concepts that I hadn't been as familiar with.
Sergey Brin and Larry Page - ...on Google
An enlightening presentation and another example of a system that's become so ubiquitous in daily life that the volume of searches they handle becomes an abstraction until it's presented in graphic terms such as they did with the globe. What I took away from the presentation more than anything technological was the idea of a collaborative work space as a means of fostering innovation. I think many libraries struggle with this and the institutions themselves, along with patron service tends to suffer from this. Tying back into the ILS article, it seems that some libraries are willing to settle for the status quo because the environment in which they work does not foster or encourage creativity and the practical constraints often seem insurmountable.

The audio is a little quiet - I was having microphone issues, but I think it's audible the whole way through.

Week 5 - Muddiest Point
At what point do librarians end up doing their patrons a disservice by having so many like resources available (like bibliographic management systems)? With so many out there and with each one operating in a different way, doesn't it make sense for a library staff to choose one and stick with it for sake of learning it and teaching it effectively to patrons?

Week 6 - Musings...
Local Area Network - from Wikipedia
Perhaps it's odd, but the thing that struck me most about this article was the information about Ethernet. As rapidly as technology appears to be changing, it's intriguing that our preferred method of network communication today is through something developed in the mid-1970s. I suppose if it isn't broken, why fix it? I feel like the article itself may have glossed over some useful points about LANs that are covered in the later 'Computer Network' article, while at the same time delving into some technical history and context that doesn't quite translate well as an introduction. I found much more about LAN clarified in the next article.
Computer Network - from Wikipedia
This article was particularly helpful to me in being able to try to distinguish the types of networks I encounter. Working on a college campus, it's helpful to know that features of the Campus Area Network can impact elements of the Local Area Network running in the building where I work. I frequently encounter this interplay when, for instance, our network printer goes down. From experience working with technical services, I've come to recognize some of the differences between our LAN causing problems with the printer vs. the CAN having larger issues that impact the printer. The article was also quite revealing about VPN, which we are finding (in our library) to be of great value for accessing electronic library materials off campus. Individuals accessing campus resources through the VPN interact in an environment that essentially recognizes their machine as being part of the campus network without their needing to be physically present or connected to said network. Practically, for libraries, this bypasses the need for proxy servers when accessing electronic databases that are IP verified. Still, it also raises potential security considerations and copyright concerns if non-campus parties were able to access the VPN (and thus library materials).
Common Types of Computer Networks - YouTube
Essentially a rehashing of the types of networks mentioned in the Wikipedia page, this didn't add much new. If I had watched this first, then read the Wikipedia article, I would have at least known the types of networks that exist. Metropolitan Area Networks, for instance, are ones that I was not familiar with existing. I took for granted that the new wireless systems that have been introduced in numerous cities are actually networks. Presumably these will continue to grow in popularity, as the expectations of ubiquitous wireless are becoming widespread.
Coyle, K. - Management of RFID in Libraries
RFID presents potential to libraries, I do admit - at the same time, Coyle make some rather broad generalizations in her argument that really make her seem disconnected from the reality of library work. RFID would certainly help speed up the checkout process for patrons, but at the same time her assertions that not having to scan barcodes and library cards would somehow reduce repetitive stress injuries is a stretch for me. I work at a circulation desk and I certainly don't find this to be an issue. I, for one, spend as much time helping patrons with reference questions as I do simply checking books out to them and reshelving them.
Considering that more resources are moving to electronic formats anyway, reference and circulation functions are becoming less independent. Patrons aren't as apt to draw a distinction between a reference librarian and a circulation staff person - they approach whoever they believe may answer their question (which is often the person closest to them at the time). What Coyle may be hinting at, but fails to draw out is the fact that RFID is helping to speed along the breakdown of traditional library job descriptions and roles.
As for privacy, I think libraries really need to look very carefully at the implications of this from all angles before wantonly instituting a system such as this. ALA has very strong guidelines developed to help preserve patron privacy, we live in a day and age where privacy is ever more difficult to control. As librarians, we should always be advocates for patron privacy and we don't want to sacrifice that trust or contribute to the erosion of privacy rights simply for the sake of patron convenience (even if it seems most important for patrons).
