Muddiest Point Week 13

Is it better to use XML schema rather than DTD? Or do you use DTD in XMLschema. I'm a bit confused.

Week 14

Cloud Computing
-some vendors same its virtual servers on the internet
-others say anything outside the firewall is cloud computing
Think about what IT always needs
-a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software.

Types of Clouds

1. SaaS: single app through browser to thousands-no upfront investment

2.Utility: storage and virtual servers access on demand

3.Web Services: APIs to exploit functionality

4. Platform as service: development envrionments as a service, build own apps

5. MSP: app exposed to IT rather than end users, virus scanning

6. Service commerce platforms: service hub that users interact with

7. Internet integration


In Vermont, patron privacy was challenged by police who were conducting an investigation. They wanted computers from the library, but were told they need a court order to ensure that privacy of others would be protected. At first it seemed that the officer would cooperate, but it became apparent that he didn't want to speak to a judge. They eventually got a court order.


Key Trends in Next Gen library

1. Communication systems change information access practices

2. All of today's new technology will be replaced by new technology

3. Small particle storage not perfect, but soon

4. Search technology will become more complicated

5. The need for speed changes library patrons lifestyles

6. Transition to verbal society

7. People want global information

8. New global systems

9. Product->experience economy

10. Libraries will be center of culture

Recommendations

Evaluate experience
Embrace new tech
Preserve mems of communities
Experiment with creative spaces

Muddiest Point Week 12

Not really a question but a comment. I'm glad that we went through XML so thoroughly. I've been doing HTML and CSS, and I know how to structure it, even if I'm not the greatest graphic designer in the world. Previously, my classes have only mentioned XML in passing, so I was never really certain as to what it was. I'm glad to have an actual idea now.

Week 13:XMLII

Document Type Definitions
-way to describe the language of document. Same way you learn a grammar for a spoken language.
-internal and external

Document Type Declaration
-DOCTYPE
-shows doc should conform to DTD
-<!DOCTYPE   >
-root element must match exactly
-XML IS CASE SENSITIVE

System Identifier
-allows you to to specify location of external file w/ DTD
-keyword SYSTEM and URI

Public Identifiers
-2nd mechanism for locating DTD
-keyword PUBLIC
-entry in catalouge
-cant combine two diff vcabs in same doc

Use DTD that are widely accepted-easier to integrate
error free
simple URI
correct media type
provide documentation

Three Parts
-element declaration:must declare each element that appears
-attribute declarations: declare list of allowable attr for each element
-entity declarations

DTD Limitations
-bad support for XML namespace
-poor data typing
-limited content model desc


XML Schemas
-use same XML syntax
-support namespace rec
-enables text element content validation
-easily create complex and reusable content
-enable modeling of programming

Raspberry Pi: A Tale of Woe

My first encounter with a Raspberry Pi (RP) was last year. It was a very brief encounter. The digital librarian decided she was going to use the Children's library OPAC as a guinea pig for her RP. She did not tell us what exactly it was, or what is was suppose to do there. The next encounter I had was this past winter. I didn't even realize it was the same device. She had built it so when a user pressed a button, a receipt with a book recommendation was printed.  Having seen RP in a library setting, I was not surprised when it was announced as a project for LIS 2000.

It is certainly no secret that the RP has caused more than one person major stress and frustration. As I am writing this I have given up for the second time. This makes me nervous, as the points are a large part of the grade in this class. So please don't fail me. I'm going to use this blog post as a sort of conversation (one-sided though it may be) about the project as a whole and my thoughts and feelings.

My classmate, Anne, mentioned this to me yesterday while we were talking about course of study and it was sort of a lightning rod moment for me. I think in large part the reason that this is so frustrating is the RP project seems exists wholly outside of the actual class of LIS 2000. We have had many interesting guest lectures, and papers pertaining to those lectures. And then sudden bursts of panic as we remember that RP is something that is suppose to be happening. It just doesn't feel like it fits in that class. It would almost make more sense for it to be a LIS2600 semester long project or something.

Something that has frustrated me personally throughout is the thrown in the shark infested waters with no chain mail feeling. I was a computer science minor (computer science for liberal arts majors but still) and for two years in my coding classes we started with the basics. And then in the final month or so, we were given our chain mail to complete our final projects. I.e. build a website from scratch. I survived the swim, but only because I experienced the training. On the one hand I understand what the goal was in giving us the project the way that we were. That is how the actual world works. We will be confronted with technology throughout our careers that will confuse and astound us. On the other hand. I am paying a lot of money to go to school to learn and hone my library and information technology skills. And as a student I expect to be taught, not stressed.

This next thing sort of ties into the previous basics statement. If we were to get basics we would be (possibly) more free to actually create something with the Pi. Like my friend at my previous library did. She did not use coder, but she still built a thing. The lack of any knowledge was compounded by the restrictive nature of the project, that is, that we had to use Google coder, an OS, when there are hundreds of things to do with a Pi, that could also be Windows based.

Which brings me to the biggest sticking point. The tools. This was discussed in class, but let's rehash it a bit shall we? SD card, mouse, separate keyboard and screen, HDMI cables, inaccessible routers, who has the kit right now. Who can afford all these extras for one use? I bought an Ethernet cable and a micro SD I didn't plan for, and don't have another use for. The logistics are shaky.

My attempts were fraught with roadblocks. The assignment instructions on courseweb are just as sparse as the google coder website itself. And it took me a while to realize that the steps were not necessarily as chronological as there seemed. I also, for some reason, had the hardest time keeping anything on my SD card, and now my mousepad is acting up. I was unable to attend the outside class time sessions. Which brings me back to the feeling of it not really belonging in LIS 2000. They were outside my set aside time.

I have no doubt that the Pi project could be a useful, interesting, and even fun project. And I also understand that we are the guinea pigs so there was bound to be issues. At this point, I want this post to be informative to the professors of this course. And to not lose 20 points. I shall post a picture with proof of my attempt to get everything running.

As you can see I tried to utilize the wireless doogle (dongle?) but that was lost on me as well. I hope this was helpful or at least informative.
