Tug of war – Convenience vs. Losing Control

Tug of war – Convenience or Losing Control – A comment on the brief history and the future direction of the Internet

Alternate title: Don’t Know What You Got (Till It’s Gone) (Cinderella)

Sometimes, if you says enough stuff, you end up contradicting yourself. I find myself in this quandary. When writing for educators, I argue that efficiency is important when asking students to work with apps, online services, or software. Spending time learning a tool takes time away from time learning with the tool so select wisely and use frequently. However, on the personal level and taking the long view, I hope we do not settle in to the use of such a small number of services that the rest are unlikely to survive and no options are unlikely to emerge.

The case for efficiency

It is not about the technology, it is about …..

This is a popular refrain. Among educators, the wording might go – it is not about the technology, it is about the learning. I doubt any educator would argue the extreme version of this straw man argument. “No biology this semester. We are going to master Google Spreadsheet!”

The true concern is that advocates should push a tool only to extent that the tool offers some advantage. This is a popular theme in education. For example, Microsoft Word is worth learning only to the extent that the product improves the efficiency or quality of writing. Extensive use of a few products might make more sense than one-time use of many products.

The case for diversity

A big part of my original attraction to web authoring was the feeling that it offered me a voice. This may have been an illusion, but the feeling of visibility was sufficient to encourage a great deal of effort. I read more and I read more widely. This increase in the content I reviewed in combination with the thinking required to craft a public product seemed productive for someone in my line of work. Again, maybe an illusion. Still, I encourage these activities. Cognitive psychologists might describe activities such as these as generative. Activities that push a bit and make us think.

Here is where a different perspective emerges. As activities become popular certain forms of change are inevitable. Popular apps and services present opportunities for those looking to make a buck. The expertise that money attracts can offer users greater ease of use and power. Simply put, those with money have an advantage. Money attracts skill.

Attraction to the tools and services that are easiest to use consolidates users making options less attractive. Over time, however, a narrow focus can limit rather than improve productivity. You probably realize how this might work. Sometimes there is something better, but you already know how to do what you are already doing AND your friends are using the same tools. Facebook makes a great example. Using Facebook represents the limit of many of my relatives digital skill and I must spend time in that environment if sharing with them is something I want to do.

Without arguing the quality of the attributes of Facebook or similar popular services, an unintended consequence (or intended if you are part of the company attempting to attract users to generate create greater profits) is a reduction in options and a dumbing down of users. The case made in Program or Be Programmed is that users fit their use to the affordances of the service – we do what is easy to do. The author argues that we may give up more than we intend as a consequence. Power and money (too often the same thing) are concentrated within fewer and fewer companies and further within the high ranking officials of the companies that attract the users. Companies begin to product what they have done rather than moving on to better products.

The solution – I suppose the solution is to recognize the narrowing of opportunities and to commit to using a variety of resources. There is more to the online world than Facebook and Twitter. There is more than the iPad.

WordPress Vulnerability – A suggestion

Several posts have indicated that WordPress blogs are being hacked. The approach involves a process of guessing (via a program) at passwords.

Since this approach likely takes many attempts, a practical and easy to implement defense is to install the plugin “Limit login attempts.” Just search for this plugin. The plugin provides some useful info. It works by refusing to accept request from an IP after a specified (by you) number of unsuccessful attempts. It will store this IP and send an email if you like.

Document Processing

Document manager (reference manager)

I am an academic. That means, in part, that I read for a living. This is not the type of reading you do to put yourself to sleep, but the type of reading you do so you know how things are done or what is presently the best information in a field that changes quickly. Reading becomes the basis for teaching and for research.

Books are seldom the focus of this work. Books are secondary sources. I may write books, but I read books to keep up with the competition and seldom to learn something new. Academics read periodicals (journals) that describe the most recent research and thinking. This material is written in a specific way with specific characteristics. This way of writing is not intended to be entertaining in that ideas are expressed in creative ways. This writing follows a pattern that is intended to communicate clearly and establish the basis for all claims made.

I am constantly looking for tools and techniques that would improve my work flow as I do this kind of reading. This was true even before the days of personal computers, I have explored many “systems” in the time I have access to technology.

My most recent set of expectations would look something like this:

  • Store and organize pdf files –  Journal articles are not provided as pdf files. A system I use to deal with this content should allow me a way to keep track of the documents and the document-related content (notes, highlights) that I create in reaction. Organization is mostly about retrieval. Will I be able to locate something a year or so later I know I read but now need access to the original to check on specifics and to retrieve details?
  • Highlight and annotate individual files – I like to think of what I do as “processing information inputs”. Reading allows some mental processing, but it helps me if I also do things like highlight and take notes. To some extent, this allows thinking beyond the information given and it also externalizes and stores ideas for future access.
  • Synchronize files across devices or with cloud storage for purposes of backup and flexible access – When I was younger, I nearly always went to the office to work. I spent a lot of time there in the evening and on weekends. One of the reasons for this was that the office was where my stuff was. It was also distraction free. As I became more secure in my career, this lifestyle became less attractive. So, I would haul a large brief case between my home and office each day. Moving to a more digital and online approach changed this. What I need now is internet access and online storage. My huge time investment in this process also encourages concern for backup. I was never that concerned that I would lose my file cabinets, but I am concerned that resources I store on a specific computer may disappear.
  • Export selected files, annotations, and citation lists. – One of my concerns when committing to any digital service involves the ease of getting my content out of the system. What happens if the system is discontinued or the conditions of use change in a way I find unacceptable? I want the opportunity extract my content from the system.

I have two recommendations. There is a free version (level) for both and this may meet the needs of most. I have found that I need to “hack” both in a way to meet my interests, but I have found work arounds that allow me to adjust the systems.

Mendeley

Mendeley allows you to upload pdfs to the cloud and to download pds from this site. You can access the cloud resources from multiple devices (including the iPad). The system includes a pdf reader allowing annotation and highlighting. Annotations and highlights are not automatically moved across devices, but you can export the pdf with your highlights. I must admit to being confused by why the tool would be designed in this way – when at home I want to see the highlights I added at work.

mendeleydesktop

The free version now comes with 2 gigabytes of storage (this was just upgraded from 1 gigabyte of storage when Mendeley was purchased by Elsevier). I must admit I am uneasy when conglomerates buy up tools (Elsevier publishes many academic journals) because I can imagine self-interests eventually imposing limitations.

To give you a sense of what 2 gigabytes provides, I presently have 315 pds stored and I am using approx 250 MB. My one complaint related to storage space concerns the gap between free and the lowest paid version. Two gigabytes is free and 5 gigabytes is $5 a month ($60 a year). Consider what purchasing 25 gigabytes of storage through say Google would cost ($30 for 25 gigabytes).

ReadCube 

ReadCube offers similar features, but saves pdfs to your computer. I found a work around by saving to a folder I synch through Box. I have 50 gigabytes of storage through Box so this eliminates the storage and synchronization issue.

ReadCube is different from Mendeley in that it is also a discovery and download tool. The system recognizes that I have access through my institution and allows me to download pdfs because of this affiliation. I can search Google Scholar or PubMed (Google Scholar for me), read the abstract, and download the pdfs for most recent citations I identify. In some cases, there is also a feature called “enhanced pdf” that accesses the reference section of an article and allows me then to use this list to identify cited sources I can also download.

The ReadCube funding model is kind of interesting (if I understand it correctly). The model is described as iTunes like which I think means a fee is charged for the download of individual articles. The price of what this article describes as the iTunes model would be difficult for most of us to cover. The work to review articles for a paper could easily run to several hundred dollars for a given piece I might be working on. It almost assumes grant funding. In addition, while students read far few articles, the cost of what they do read would have a larger impact. At the level of the institution, I would be very surprised if subscriptions through the  library will not continue to be the most efficient model. If ReadCube could negotiate a more moderate rate from publishing companies based on a greater volume of business, perhaps something close to an iTunes model will work. At present, ReadCube recognizes my affiliation with a university and allows my to access resources because the University has committed to the subscription model. So, it is not my situation that concerns me, but rather the survival of the company based on the business model assuming customer payments.

Web of Things

The Web of things is an abstract and futuristic concept. We have experience with desktop computers, cell phones and maybe even printers, but beyond that the concept gets a little bit weird. We know it is supposedly coming, but we are not certain when it will arrive or what it will look like when it gets here

Here is a new personal experience that has expanded my vision a bit. We own a lake property located some 350 miles from our home and we get there when we can. We made the trip for the holiday. One of my original fears when purchasing the property was that not being on site I could experience serious issues with vandalism or some serious malfunction in the heating system. Things went well for the first year. We have encountered some issues most would find foreign. For example, the drain field on our septic system froze limiting our use of water for the rest of the winter. This was manageable. One of my original concerns manifest itself this trip. The furnace had stopped working (a component locked up preventing the furnace from igniting). With temps below 0, water in the pipes froze. It ended up we were very lucky as the plastic cover for a filtration system  must have been the weak place in the system. This system split and relieved the pressure on the rest of the pipes (we do turn off the water when we leave, but there is still water in the systems).

Anyway, we had to call both a plumber and someone to work on the furnace. Expensive, but the situation could have been far, far worse.

The guy working on the furnace recommended that we consider a new thermostat system. The immediate motivation was that the system connected to the Internet and would send us emails if there was a concern. However, the system does much more.

The EcoBee

The Ecobee smart thermostate is web enabled. It connection with a cloud location and through this server we can control the thermostat and download data. The system also sends automatic alerts (emails) when preset conditions are met. For example, it would have emailed us when the furnace would not ignite and the temp fell below a temp that was dangerous for the pipes.

This is one of those smart systems that has economic benefits – you can set temps for times of the day and days at a time. You can turn the temp down to 50 when you are not present and have it raise to 65 an hour before you arrive. You can adjust the temp from your phone before you get out of bed in the morning.

I like the ability of the system to store data – just because it is fun. For example, because of the large windows in the home, the air conditioning cannot keep up with rising temperatures in the summer. So, it will be interesting to determine how much of the time in the summer the house is warmer than the setting for air conditioning.

ecobee3

 

If you have imagined our situation, it may occur to you that this is not a perfect solution. For example, the alert system would have allowed us to prevent the problem we had this time, but what would happen if the electricity or web went down? This is presently a limitation of the Ecobee system. You would think the server would be able to identify when it was no longer receiving a signal from a given location, but this appears not to be something the present system is designed to address.

There are some other interesting features; e.g., we can get temps inside and outside from this remote location and we can get the forcast for the coming week. You can get information from your thermostat including the weather forecast for the next week. The thermostat is a functional computer with Internet access but the software is limited to weather data.

I am assuming it will take a long time to recoup our purchase investment on the basis of energy savings, but it does gives us some protection against certain problems and it is fun to check the most recent data from a computer or phone.

It occurs to me that there is some danger in the complexity of the system – one messed up setting and I could turn on the air conditioning in the middle of winter.

 

Feedly as a replacement for Reader

One of the biggest tech stories of the week was Google announcement that it would shut down Reader. This service is used by many to organize their RSS feeds – the syndication that announces new content. It is possible you follow such feeds using another app, but it is likely that this app loads information from Reader. For those of us who use RSS feeds to follow trusted sources, the loss of Reader is significant. This post features what is likely the front runner as a replacement.

Among those quick to offer options, Feedly seems the present choice. Since the recommendation has been so common, I thought it might be helpful to offer some comments on use. I review my feeds from my iPad, but it is helpful if a service can be accessed using multiple platforms. Feedly is available from Android and IOS and from an app operating within the Chrome, Safari or Firefox browser. Hence, you can work from your tablet, phone, or computer.

If you are a Google Reader user, migrating to Feedly is an easy process. Simply put, you connect to Feedly and login with your Reader name and password. Your existing feeds are now available in Feedly.

Once you have made the transition, you will want to be able to add and delete feeds. The addition of new feeds had me confused for a bit – it appears to work a little differently from a tablet than from a computer.

Here is the procedure from the app within a browser (Chrome in this example).

There is an icon in the upper left-hand corner of the app I assume is called “Home”. Selecting this icon, reveals then organizational structure you have generated for your feeds, but also the “add website” button. To add a new feed, select this button and then enter the URL for the site you want to follow.

feedlychromeapp1

I was unable to find a comparable button within the iPad app. Here the process seems to work in a different way. You can use Feedly to visit web sites much in the way you would use a browser. You search for a site using the search icon in the upper right-hand corner of the app. First search for the site. Options matching your search are listed and you select the one you want to display the site. Once displayed a + will appear at the top of the app. Selecting the + indicates that you want to add the feed. You will be asked to indicate how you would like to organize the addition and then you are finished.

The money does matter

One of my initial reactions to MOOCs was based on personal experience as the instructor of large courses and administrator of a department with many large courses.  It was like something was obvious to me but not others. Do people assume this is our preferred method of instruction? Finally, I have encountered someone with a similar perspective.

A big part of this situation is about the money. Those of us who we teach under these circumstances allow others to teach groups of 25 or work with grad students. The complaints obviously annoy me. Take away the large lecture courses and see what happens to tuition!

The learn to program campagin


 

Hmm..    There has been long been an educational interest in programming. Clearly, coding can be a vocational skill. If there has been a unique component to my professional skill set, it has been that I can write the code to create online learning environments and collect data on how the environments are used.

What is a little more “iffy” is the proposal that coding experience develops other kinds of skills any more than say working on large writing assignments. In fact, the research tends to show that higher order skills such as problem solving are largely domain specific. This, for example, is how I remember the large volume of research on the LOGO programming boom. The notion that a focus on a specific skill has general consequences makes about as much sense as Chris Bosh contending that Bill Gates should learn to play basketball because it is a great way to stay in shape. Developing the specific skill would certainly not be the most efficient way to accomplish the desired end.

Pro programmers are not actually the experts on the general benefits of developing such skills.
