Raspberry Pi is sold out?

If you've been following my interest in the Raspberry Pi single-board computer, and some of the projects that students might do with it, you might be interested to know that Raspberry Pi launched this morning, 6:00AM GMT (or midnight, Minnesota local time.)

By the time I checked into the site this morning, it seems the initial batch of Raspberry Pi have sold out. This despite having entered into licensed manufacture partnerships with two British companies, Premier Farnell and RS Components. They'll be manufacturing and distributing the devices on behalf of the Raspberry Pi Foundation, and handling the distribution of our first batches as they arrive in the country. That the first batch of Raspberry Pi have sold out in the first few hours after launch speaks to the great interest the community has in this small computer.

Congratulations to the Raspberry Pi folks for their very successful launch. We'll pick up some test units for UMM when they get more in stock.

Raspberry Pi goes on sale tonight?

All indications point to the Raspberry Pi going on sale tonight, midnight our time (6AM GMT.)

There are lots of new projects that you can do on the Raspberry Pi. I discussed several of these in my other post:

  1. A possible replacement for lab PCs or Internet "kiosk" PCs
  2. A display device, like the video display outside Higbies (over the network, or from a USB flash drive)

Personally, I'd like to use one at home to build a small "webcam" device. When my wife & I visit friends in the Cities, we leave our 3 cats unattended overnight. Call me sentimental, but I'd like to hook up my cheap webcam to a Raspberry Pi, aim it at the living room couch, and have it snap a picture every 5 minutes or so. Then I can "virtually" check in with the cats while I'm away for the evening.

I'm also interested in trying the Raspberry Pi as a desktop replacement. With Gmail and Google Docs, most of my day is spent in a web browser. The operating system has become (mostly) extraneous. The Raspberry Pi will ship with a Linux distribution (based on Fedora) - which includes the familiar Firefox web browser. Can I do everything I need at work "out of the box" using Raspberry Pi? I'll let you know, once I get my own Raspberry Pi.

A balance of control

I've often advocated for "the right tool for the job", generally preferring that faculty and staff not be overburdened with too much IT control and "over-management". This works well to support the campus activities, our main focus of educating our students. However, this needs to be balanced with central IT management for critical systems, sensitive information, or areas of security.

In particular, we want to avoid the situation at the City College of San Francisco (CCSF), where personal personal banking details and other private information was leaked for years:

Each night at about 10 p.m., at least seven viruses begin trolling the college networks and transmitting data to sites in Russia, China and at least eight other countries, including Iran and the United States, Hotchkiss [David Hotchkiss, the chief technology officer] and his team discovered. Servers and desktops have been infected across the college district's administrative, instructional and wireless networks. It's likely that personal computers belonging to anyone who used a flash drive during the past decade to carry information home were also affected.

As PJ Connolly writes in eWeek, the prevailing view in many organizations is "IT security .. isn't cheap and it won't make any money for the organization, and therefore, it's as low of a priority as one can get away with."

Computing Services (Morris) and the Office of Information Technology (Twin Cities) work together very closely to monitor our security. We have processes in place to track suspicious behavior on the network, and alert us if we see traffic indicative of an issue. We have security processes and standards to protect data - on your desktops, and on our servers.

For example, in the last year, Computing Services has rolled out "Active Directory" to many staff areas. You may view Active Directory (AD) as just providing online storage (your H: and S: drives.) But Computing Services also can use AD to automatically install patches and keep critical software up to date. In the event of a virus sweeping across campus, AD will allow us to quickly distribute a patch to address the vulnerability. This provides a good balance of "benefit" (to you) with "IT control" (security.)

Not all areas have moved to Active Directory yet; this will be an ongoing project. But it's one example where Computing Services is working to keep the campus safe.

Soft skills are important

During times of change, it's important for leaders to engage their teams. Many managers may be uncomfortable with this level of openness, but Madeline Weiss & June Drewry in "3 Easy Ways to Get Better at the Hard Stuff" share 7 tactics to help lead through uncertain times.

  1. Set up a team to guide people reluctant to change.
  2. Have a compelling vision or purpose to share.
  3. Engage both the rational and emotional sides of your staff.
  4. Target and measure desired outcomes.
  5. Foster ownership, commitment and idea sharing.
  6. Make two-way communication "relentless and ­boring."
  7. Build credibility and momentum with quick wins.

These should feel familiar if you've read my blog before. These speak to being "present" as a leader, sharing the broad themes, building credibility, and relationships.

The article focuses on 3 techniques that are probably outside most managers' comfort zone:

1) Have a compelling vision or purpose to share.

Cutting costs and increasing revenue aren't compelling to staff in the same way a visionary goal can be. What does your organization's vision say to employees? All too often, CIOs create vision statements focused only on IT's role in the company. Redirect that vision to connect more directly with a noble cause that will motivate extraordinary efforts.

2) Foster ownership, commitment and idea sharing.

Get staff involved in any transformation plan as early as possible to avoid setbacks later on. CIOs can play a central role in times of change by asking staff at all levels to identify barriers - impediments in structure, attitudes, systems, styles, processes, performance measures, incentives or rewards - and then work together on busting them.

3) Make two-way communication "relentless and boring."

CIOs must not only communicate messages many more times than they might like but must also do so in multiple formats. That means writing blogs, holding breakfast and town hall meetings, sending weekly emails, broadcasting videos and chairing panels of company leaders. This is one area where you can never overdo it.

Update on network upgrade

As you know, Computing Services has been working with the Twin Cities network team to upgrade our campus network and wireless. Some on-site work began in January and February, but the upgrade won't be complete until summer. I wanted to share an update on our network upgrade project. I have also reviewed this information with Planning Committee and Academic Support Services Committee.


General schedule

March:

  • Bring in new network gear at Behmler Hall. This controls the "core" of our campus network.
  • Review of campus network, including wiring and equipment.

April:

  • Upgrade network equipment in residence halls, campus apartments, and similar non-academic buildings.

May: (after graduation)

  • Upgrade network equipment in academic buildings. Computing Services will coordinate with the summer program to minimize the impact of these changes.

During the summer, we will upgrade the wireless network across campus. Based on similar network upgrades at the Twin Cities, we expect to see a 20% improvement of our wireless network just by replacing the wireless access points with new devices. This will also give us a new wireless network for guests to use when visiting the campus. After the wireless upgrade, we will collect statistics and analyze our wireless network coverage, and work to improve wireless in areas that need the most help. Our focus areas will include the Library, Student Center, and HFA buildings.

We expect to finish all network upgrades before the start of Fall term.


Next steps

We installed a new network router last week. Our next steps will bring this into the campus network:

Wednesday, February 29 at 6:00am

  • The Twin Cities network team will activate the new router. You may see the network become slow for 5-10 seconds if you are logged in at 6:00am. We are making this change in the morning to avoid impact to the campus.

Monday, March 12 (first day of Spring Break week)

  • Start routing traffic from each of the campus buildings through the new router. This work is likely to be more noticeable, up to 5 minutes but only for the building that is being activated at that time. (For example, you may not be able to send emails in Gmail or edit new documents in Google Docs during these 5 minutes.) Unfortunately, the Twin Cities network group is not able to make this change after hours, so we have scheduled the first day of Spring Break week to minimize the impact to teaching & learning. We will share a schedule in the next few days to indicate when each building will be added to the new router.

After these changes, we do not expect to have any visible changes on the network until after graduation in May.

If you have questions about the progress of our network upgrade, please feel free to call, email, or visit.

Thanks for the great feedback

As you know, I am leading an effort to refresh our campus technology strategy. To make sure the strategy meets the campus needs, we have been soliciting feedback from all areas (students, faculty, and staff.) Last week, we had feedback sessions with staff and students. Earlier this week, we had another feedback session with faculty.

Yesterday, I spent some time in the Student Center gathering your opinions about how we use technology, and what you think we should be working towards. We had a great response from students (and a few staff/faculty). You put lots of great ideas on the "paper wall".

Also, thanks to Zak and Manjari for helping to put together another student feedback session last night. We had an amazing turnout, and lots of good ideas - and a lot of overlap, which indicates the right priorities came out of the feedback session.

We plan to use your ideas as part of our process to update the campus technology strategy, which will help guide the campus in our projects and planning.

We need your comments

Our committee has been working on the updated IT Strategy for Morris. Over the last week, we held separate IT feedback sessions, seeking your comments about how we use technology, and what you think we should be working towards. To everyone who attended: thank you for your time, and your very constructive comments!

Although we haven't had a very large turnout in these sessions, we have generated some solid campus feedback. Those of you who did attend agreed that the issues raised seem representative of the campus - so I'm pleased with our progress so far. But I'm also trying other options to gather additional campus feedback.

Please join me on Thursday this week, 10:00am-noon in the Student Center, next to Higbies. We'll have a "wall" of blank paper for you to write a comment or priority or need about campus technology. Add a new thought, expand someone else's idea, or just "star" a great idea that you agree with.

I think this has the potential to draw a lot of great comments. I look forward to hearing from you!

What's next: Raspberry Pi

At heart, I'll always be a technology geek. Keeping that at my "core" provides me a continual sense of wonder about technology, and renewed interest in what is coming next.

One project that I've been following with great interest for some time is the Raspberry Pi project. (That's "pi", as in the Greek letter. Cute, eh?) Raspberry Pi is a small computer, with a circuit board the size of a credit card. Yet it's powerful enough to do lots of interesting and useful things.

Raspberry Pi logo

Raspberry Pi is based on a special processor called an "ARM". Your PC or Mac probably runs an Intel processor. The ARM is just like that, but smaller, and requires very little power (the Raspberry Pi uses the same 5 volt power plug that you use to charge your phone.) You can't simply run Windows or Mac programs on an ARM, but you can adapt them through a process called "recompiling". Or, developers can just write new programs with Raspberry Pi in mind.

Raspberry Pi board

The group behind the Raspberry Pi aims to bring inexpensive computing devices to education. Their ideal is to turn Raspberry Pi into an affordable computing platform to help introduce the next generation of students to technology. The basic model will sell for only $25.

As we wait for the first units to go on sale, I start to wonder how we might apply the Pi to our campus technology and learning. I've discussed a few options with KK and Nic in our computer science department. Here are some of my first thoughts for student projects:

- A possible replacement for lab PCs or Internet "kiosk" PCs

Despite its small size, the Raspberry Pi has enough computing power to support a modern graphics desktop environment, built on Linux and the familiar Firefox browser. I'm curious to see how Raspberry Pi might fare as a dedicated "web browser" machine, suitable for kiosks.

Could Raspberry Pi also replace some of our lab PCs? This might require "virtualizing" some of our more powerful applications, so they actually run on a server somewhere, and get displayed on Raspberry Pi. This is certainly possible. More technical folks might recognize the "VNC" viewer; this also runs on the Raspberry Pi.

- A display device, like the video display outside Higbies

This would make an excellent project for a student. Could we see future displays around campus that are built on the Raspberry Pi? I see two possibilities, depending on need and connectivity:

  1. Raspberry Pi might fetch images over the network from a web server, then cycle through those images on a monitor. At convenient intervals, Raspberry Pi might refresh it's copy of the images. This makes it very easy for someone to update every connected display device, simply by changing images on a web server.
  2. For spaces that do not have a network connection, an enterprising student might write a program that automatically copies images from a USB fob drive, then cycles through those images on a monitor.

Even more interesting would be a student project to automatically display a Powerpoint presentation on a monitor, using Raspberry Pi. This would make it much easier for campus owners to put new content on the display devices.

The #1 productivity killer

"Meetings. You can't live with them, and you can't live without them." In his article, Hunting Down the No. 1 IT Productivity Killer, Marc Schiller of CIO Insight discusses a few best practices from the venture capital community, and how they might be applied to make our meetings more focused.

Marc gives this advice:

  1. Replace the 60-minute meeting with 20-minute "units". This is just the right amount of time to do something well. If you need more time than that, it's up to the convener to convince the participants that 2 or more "units" are necessary for the topic.
  2. Replace agendas with goals. Don't just talk about a topic, work towards a resolution.
  3. Orient the meeting for follow-up and action items. The real purpose of meetings is to agree to next steps. Don't feel you have to "do" everything in the meeting, assign tasks that will be worked on outside the meeting.

As Matt Senger (Computing Services, UMM) commented to me: "Meetings are like Tribbles." (They multiply.) It's your job as meeting convener to ensure your meetings remain relevant and productive.

Savings from standards

I wanted to share this update from the IT Leadership committee ("ITLA") that I'm part of. As you probably know, shortly after I came to Morris, I helped standardize the PC ordering process. We now try to order standard PC models, rather than build unique configurations for every order, and no two systems alike.

This isn't 100% strict, of course. We respond to faculty's specific needs, and have ordered several "custom" configurations where needed. But for most PC orders, faculty and staff just want a "PC", and we help them order a standard configuration.

Ordering standard PCs results in budget savings to the campus, because the U of M can negotiate a lower price on these standard models. And this helps reduce the total IT effort to support those PCs over time - if most PCs use the same/similar configuration, it's much easier to support the software that runs on them.

In December, the Senate Committee on Information Technology (SCIT) at the Twin Cities campus reviewed the University's strategic sourcing model, and its results. The analysis shows the success ITLA had in reducing overall IT support costs through ordering standard PCs. IT generated the second largest savings, largely due to using these standard PCs.

It's important to note that the use of these standard machines is voluntary and yet we are seeing an 80-90% percent adoption rate across the U of M. We see slightly better adoption at Morris, closer to 90-95%.

What have I done for you lately?

Supporting IT is often compared to running the trains: people only notice when the trains are late. No one really notices when IT runs well, only when things break. But Computing Services has worked very hard to bring new improvements to the campus, without affecting what you do. I wanted to take a moment to recognize some of the work that Computing Services has done for the campus:

Google+

Since last year, we've had the ability to use Google+ for social connectivity across the University. For example, I use Google+ Hangouts in committees that span different campuses, so we can be face-to-face without having to drive 3 hours to the Cities.

Many Morris faculty have started using Google+ in their classes, too. It's a great way for students to stay connected with each other, and with their professor. Using "Circles", you can control privacy, or "follow" someone (like a professor) to stay abreast of announcements and other important updates.

However, until recently, Google+ required users to be 18 years or older. This is fine for most students; they are already 18 when they come to Morris. But many of our PSEO students are not yet 18, so have been unable to use Google+.

Aubrey McIntosh brought this problem to my attention at the beginning of this semester, and I immediately worked with OIT and our partners at Google about the need to let PSEO students participate in Google+. We're under non-disclosure rules, so I cannot give details, but you may have noticed that Google+ now allows students 13 years and older. This change happened about a week after we brought the concern to Google.

While I can't claim sole credit here (Google was going to do this anyway) I think it's fair to say that our conversations with Google helped move up the timeline. That's the value we bring to the campus: we serve the campus, to help faculty & students in the teaching & learning mission.

NEH technology grant

Before the break, Jayne Blodgett and I discussed how to enhance teaching & learning through technology. Working with Kristin in the Grants office, we collaborated with Tisha, Heather, and Pam to draft a grant proposal to the National Endowment for the Humanities (NEH) on technology in the classroom.

Our grant proposal focused on the benefits of mobile learning, or "mLearning", and how to experiment with this at Morris. Grants are a wonderful opportunity to try new things, and we haven't had much experience with mLearning at Morris. Our proposal (due in early March) asks for monies to purchase iPads and network infrastructure to support a mobile learning initiative at Morris, using iPads to enhance college writing.

Zimride

For years, Morris has used a wiki-based ride board. But this was awkward to use, and often very out of date. Rather than use this ride board, students turned to the mail list, offering and asking for rides. Due to the volume of messages on the mail list, we needed to find another alternative to the wiki ride board.

Last year, Computing Services followed up on a suggestion, for a new student ride-sharing system. Through support of MCSA and TechFee funding, we purchased into an online service called Zimride. This new service has hooks into Facebook and Google Maps to help students get connected.

Computing Services manages the Zimride offering for the campus - including advertising and communication - and participates in a regular check-in meeting with Zimride. In January, Zimride shared some interesting ride statistics with us. At the end of the year, Zimride posted their top rankings: total new users, new users as a percentage of the campus, new rides posted as a percentage of the campus.

  • Morris ranks #1 in % new users, with 28% of our students choosing to use Zimride. (The #2 school is only 18%.)
  • We are tied for #1 in % new rides posted, at 30%. (We are tied with James Madison University.)

It's worth noting that we have been using Zimride since September 2011, so our stats represent only 4 months' usage.

Computing Services believes strongly in its service to the campus. We exist in a partnership with all faculty, students, and staff. Each initiative mentioned here came about from conversations with the campus. It's our job to respond to your needs, and our pleasure to make it happen.

Relative Importance in IT

Some time ago, I posted an online poll to survey the relative importance of four qualities at various levels in an IT organization. With the help of other bloggers, and through retweets, we got the word out to as many IT folks as possible. We received responses from all across the globe (though most were from the US) representing private industry, higher education, and government. The poll was up for about two months, but most of the responses came within the first few weeks. I'd like to share the results with you.

The survey asked respondents to self-identify their role in the IT organization ("Staff", Team lead", "Manager", "Director", "CIO") and to rank four qualities ("Technical", "Strategic", "Interpersonal", "Finance") relative to one another. This was not just a simple 1-2-3-4 prioritization exercise. Rather, the survey asked folks to consider how each quality fit into the overall importance of their work, and rank the importance of each on a 0-100 scale, where the total of all four also must be 100.

I sorted the data by role, and averaged each quality for that role. This provided a good reduction of the data. The standard deviation was a little wider than I'd prefer, but this was an unscientific poll with only self-selecting respondents.

This is a similar approach that many other surveys have taken in measuring relative importance. However, I admit that my poll was an unscientific one. Yet the results were very consistent across each role, and somewhat surprising.

First, let's review the four qualities in more detail:

  • Technical: The tasks that are very "hands-on" by nature, often managing servers or databases, or supporting other systems or desktop environments.
  • Strategic: Time spent thinking about the overall IT organization, and how the organization needs to respond to meet new challenges.
  • Interpersonal: Building relationships, the "give and take" of interacting with others.
  • Finance: Factoring in costs, either at the small scale (tools, etc.) or at the larger scales (budgets, etc.)

Note that these aren't "skills" per se, but qualities that are important to the work performed within each role. You might consider the Relative Importance the contribution of each quality to the role's function in the IT organization.

And how these qualities were ranked relative to each other:

relative-importance.png

But what does this mean? There are several interesting things about these results. Let me note a few key interpretations of the data, as trends:

1. The vanishing value of Technical, and the balancing act of the manager

Not surprisingly, the relative importance of Technical drops very quickly, the higher you are in the IT organization. For a CIO, the importance of Technical is almost zero. That's not to say that a CIO may not have the skills to, say, set up a Linux server, or to edit web pages. But this is not what a CIO typically does in his or her role, so it ranks as not very important compared to the other qualities.

This is an important trend in understanding how to communicate with those around you, how to frame a position. You may have experienced this, if you ever tried to convince your director or CIO to adopt a new path in technology. You can't make a compelling case based simply on technical merit. Rather, your case will be better received if you focus on how your idea will benefit the organization (Strategic) or will help others to be more effective (Interpersonal).

Also, note what happens at the manager level. Three of the four qualities have equal relative importance; they are equally weighted for the manager. This is often why IT managers have the most difficulty in reaching the next level in an organization. Successful managers have learned to balance their attention across Technical, Strategic and Interpersonal. They have the necessary technical background to address IT issues with their staff, and have developed a more strategic view of the organization.

There's a conventional wisdom for new managers that "what got you here [manager] won't get you there [director]." Rising through the ranks of an IT organization, Technical plays a key role at the staff, team lead, and manager level. In most IT organizations, staff become team lead and manager through demonstrating their proficiency in technical systems. The reward for good work can be more work, and eventually a bump up to the next level.

Until you reach manager. At that role, your technical background becomes less important to reach the next level. But to take that next step to director requires putting aside that technical background, to focus more on larger issues. When you've spent so much time and energy balancing the demands of Technical/Strategic/Interpersonal, it is awfully hard to finally "let go" of Technical so you can focus your attentions on new strategic thinking. Note how Strategic rises considerably in the transition from manager to director, yet Technical drops further in relative importance.

2. The sudden focus on Finance

If you watch the Finance line, it's fairly flat between staff and team lead, and between manager, director, and CIO. But at that increment from team lead to manager, there's a step up.

Speaking from my own background, at the staff and team lead levels, there usually isn't much need for financial planning. Sure, you need to keep costs in mind when you're working on systems or proposing new changes, but most organizations leave the finances to upper management.

And that's what we see in the survey. When you become a manager, you now need to balance a budget for your unit. In some organizations, the manager may only need to provide a purchase plan. In larger units, the manager may be responsible for submitting a fiscal budget.

There isn't much change in Finance as you reach the upper levels of director and CIO. While the scope of these positions is quite different, the thought process is about the same. The relative importance of Finance remains approximately flat after manager.

3. Managing relationships at all levels

It's often true in executive leadership that "it's not what you know, but who you know." While the relative importance of Interpersonal seems flat across the different IT roles, there's a definite upward trend the higher you are in the organization.

Technology staff and team leads need to maintain good working relationships with one another. At the other end, the CIO needs to build partnerships and navigate organizational politics to achieve strategic goals.

Technology is an ever-changing landscape, and CIOs often find themselves the "change agent" for the institution. To implement change successfully, the successful CIO often relies on social networks with others. There should be little surprise in the sudden uptick in Interpersonal's relative importance at the CIO level.

New login page coming soon

The Helpdesk already emailed the campus about this, but I wanted to share this update as well:

Just a reminder that on February 15, the Office of Information Technology (OIT) at the Twin Cities campus will upgrade the system that manages logins. In the past, the University of Minnesota has used a "Central Authentication Hub" system, which is an older login method. The new login system is called "Shibboleth", and gives us the ability to support more third-party applications using your University login.

We've actually been using a version of Shibboleth for a while now - Google and Zimride both use Shibboleth. The change on February 15 will phase in an updated Shibboleth system.

There are many changes happening "behind the scenes", but what you'll notice is a new login page. The newly designed sign-in page offers significant improvements. It has been updated to meet University branding standards, to accommodate screen readers, and to display on mobile devices. For a visual demonstration of the changes, compare the following:

Computing Services has been working very hard over the last few months, making sure all our applications are ready for the new version of Shibboleth. This is important, because any applications that still use CAH for authentication will continue to use the old sign in page. There will be no single sign on (SSO) between Shibboleth and CAH applications.

Since we've done this work ahead of time, you shouldn't notice any odd behavior during the upgrade - aside from the login page looking very different.

As always, we still recommend that you logout of applications (and/or close your browser) when you are done using them. There will be no single sign out between CAH and Shibboleth applications; users must sign out of both sets of applications separately. There will be no single sign out among Shibboleth applications. This means that users must sign out of each application separately.
