Clip-Clip

So recently I started cutting my own hair. 

Uh, yes!

Not sure what made me actually do this...

But it just seemed like I was wasting money at the Hair Cuttery on something that I could do myself. 

Also, I remember fondly how my dad used to cut his own hair for decades.

So I gave it a try--that's not me in the picture!

I purchased a simple Wahl clipper and went at it.  

First a little tentatively and then more boldly as I got the hang of it. 

The best part of the clipper is the color-coded guide combs so I don't completely screw this up. 

What I also like is that ability to give myself a little trim whenever I want. 

Don't have to wait to get to the barber or to wait on line there. 

So far so good, thank G-d--no big hair disasters.  

And frankly, I look a lot happier than the guy in this photo. ;-)

Running IT as an Ecosystem

The New York Times (27 November 2011) has an interesting article under "bright ideas" called Turn on the Server. It's Cold Outside.

The idea in the age of cloud and distributed computing, where physical location of infrastructure is besides the point, is to place (racks of) servers in people's homes to warm them from the cold.

The idea is really pretty cool and quite intuitive: Rather than use expensive HVAC systems to cool the environment where servers heat up and are housed, instead we can use the heat-generating servers to warm cold houses and save money and resources on buying and running furnaces to heat them.

While some may criticize this idea on security implications--since the servers need to be secured--I think you can easily counter that such a strategy under the right security conditions (some of which are identified in the article--encrypting the data, alarming the racks, and so on) could actually add a level of security by distributing your infrastructure thereby making it less prone to physical disruption by natural disaster or physical attack.

In fact, the whole movement towards consolidation of data centers, should be reevaluated based on such security implications. Would you rather have a primary and backup data center that can be taken out by a targeted missile or other attack for example, or more distributed data centers that can more easily recover. In fact, the move to cloud computing with data housed sort of everywhere and anywhere globally offers the possibility of just such protection and is in a sense the polar opposite of data center consolidation--two opposing tracks, currently being pursued simultaneously.

One major drawback to the idea of distributing servers and using them to heat homes--while offering cost-saings in term of HVAC, it would be very expensive in terms of maintaining those servers at all the homes they reside in.

In general, while it's not practical to house government data servers in people's homes, we can learn to run our data centers more environmentally friendly way. For example, the article mentions that Europe is using centralized "district heating" whereby more centralized data center heat is distributed by insulated pipes to neighboring homes and businesses, rather than actually locating the servers in the homes.

Of course, if you can't heat your homes with data servers, there is another option that gets you away from having to cool down all those hot servers, and that is to locate them in places with cooler year-round temperatures and using the areas natural air temperature for climate control. So if you can't bring the servers to heat the homes, you can at least house them in cold climates to be cooled naturally. Either way, there is the potential to increase our green footprint and cost-savings.

Running information technology operations with a greater view toward environmental impact and seeing IT in terms of the larger ecosystem that it operates in, necessitates a careful balancing of the mission needs for IT, security, manageability, and recovery as well as potential benefits for greater energy independence, environmental sustainability, and cost savings, and is the type of innovative bigger picture thinking that we can benefit from to break the cycle of inertia and inefficiency that too often confronts us.

Running IT as an Ecosystem

The Printer’s Dilemma

There is a lot of interest these days in managed print solutions (MPS)—sharing printers and managing these centrally—for many reasons.

Some of the benefits are: higher printer use rates; reduction in printing; cost saving; and various environmental benefits.

Government Computer News (5 April 2010) has an article called “Printing Money” that states: managed printing is an obvious but overlooked way to cut costs, improve efficiency, and bolster security.”

But there are also a number of questions to consider:

- What’s the business model? Why are “printing companies” telling us to buy less printers and to print less? Do car companies tell us to buy less cars and drive less (maybe drive more fuel efficient vehicles, but drive less or buy less?) or do food companies advise us to buy less food or eat less (maybe eat healthier food, but less food)? To some vendors, the business model is simple, if we use their printers and cartridges—rather than a competitor’s—then even if we use less overall, the managed print vendor is getting more business, so for them, the business model makes sense.

- What's the cost model? Analysts claim agencies by moving to managed print solutions “could save at least 25 percent of their printing expenses” and vendors claim hundreds of thousands, if not millions in savings, and that is attractive. However, the cost of commodity printers, even the multifunction ones with fax/copy/scan functions, has come way down, and so has the print cartridges—although they are still too high priced—and we change them not all that often (I just changed one and I can barely remember the last time that I did). As an offset to cost savings, do we need to consider the potential impact to productivity and effectiveness as well as morale—even if the latter is just the “annoyance factor”?

- What’s the consumer market doing? When we look at the consumer market, which has in many analyst and consumer opinions jumped ahead of where we are technologically in the office environment, most people have a printer sitting right next to them in their home office—don’t you? I’d venture to say that many people even have separate printers for other family members with their own computers set ups, because cost and convenience (functional)-wise, it just makes sense.

- What’s the cultural/technological trend? Culturally and technologically, we are in the “information age,” most people in this country are “information workers,” and we are a fast-paced (and what’s becoming a faster and faster-paced) society where things like turn around time and convenience (e.g. “Just In Time inventory, overnight delivery, microwave dinners, etc.) are really important. Moreover, I ask myself is Generation Y, that is texting and Tweeting and Facebooking—here, there, and everywhere—going to be moving toward giving up there printers or in fact, wanting to print from wherever they are (using the cloud or other services) and get to their documents and information immediately?

- What’s the security impact? Understanding that printing to central printers is secure especially with access cards or pin numbers to get your print jobs, I ask whether in an age, where security and privacy of information (including corporate theft and identity theft) are huge issues, does having a printer close by make sense, especially when dealing with sensitive information like corporate strategy or “trade secrets,” mission security, personnel issues, or acquisition sensitive matters, and so on. Additionally, we can we still achieve the other security benefits of MPS—managing (securing, patching etc.) and monitoring printers and print jobs in a more decentralized model through the same or similar network management functions that we use for our other end user-devices (computers, servers, storage, etc.)

- What’s the environmental impact? There are lots of statistics about the carbon footprint from printing—and most I believe is from the paper, not the printers. So perhaps we can print smarter, not only with reducing printers, but also with ongoing education and sensitivity to our environment and the needs of future generations. It goes without saying, that we can and should cut down (significantly) on what and how much we print (and drive, and generally consume, etc.) in a resource constrained environment—planet Earth.

In the end, there are a lot of considerations in moving to managed print solutions and certainly, there is a valid and compelling case to moving to MPS, especially in terms of the potential cost-saving to the organization (and this is particularly important in tough economic environments, like now), but we should also weight others considerations, such as productivity offsets, cultural and technological trends, and overall security and environmental impacts, and come up with what’s best for our organizations.

The Printer’s Dilemma

Zipcar = Cloud Computing

No, not exactly. But they actually do have a lot in common in that they are both about sharing resources and using them to achieve cost-savings and flexibility.

An article in Fortune Magazine (September 14, 2009) on Zipcars really got me thinking about this.

With cloud computing, we are sharing our IT infrastructure, storage, and/or applications with others and using the services of cloud providers. It is one big virtual environment, where instead of everyone having their own technologies and applications, we make use of shared resources and we meet our information technology needs on demand and pay only for what we use.

Zipcars has the same-shared model as the cloud, and shifting toward this new paradigm is going to help preserve the environment.

Usage: Like cloud computing, Zipcars provides for the use of automobile when you need one and you pay by the hour or day, according to what you use. It’s flexible, saves money, and cuts down on the number of vehicles on the road and therefore on the pollution associated with them.

Cost: Both Zipcars and cloud computing cost pennies on the dollar. For a basic $50 membership and $11.25 an hour you can drive a Zipcar (note: drivers who give up their own cars save an average of $800 per month). For 12-25 cents per month you can store a gigabyte in the cloud or for 10 cents-$1.25 an hour you can process tasks on the Elastic Computer Cloud (EC2).

Functionality: Zipcars move people around and cloud computing moves data.

Centralization: Zipcars are co-located in “company created ‘pods’ or group of cars in parking lots or garages,” and cloud computing services are centralized in data centers of large cloud providers (like Google, Amazon, Microsoft, and IBM)

Market: Zipcars has grown already to 325,000 members and is growing 30% a year with a overall market for shared vehicles expected to balloon to $800 million over the next five years (Fortune), and business IT spending on cloud computing is expected to rise from $16 billion last year to $42 billion by 2012 (IDC).

Users: Major companies (not just individuals) are using Zipcars—so far “about 8,500 companies have signed up, including Lockheed Martin, Gap, and Nike.” And brand name companies are signing up for cloud computing, such as NY Times, NASDAQ, Major League Baseball, ESPN, Hasbro and more. (http://www.johnmwillis.com/other/top-10-entperises-in-the-cloud/).

Going green: Each shared Zipcar “takes up to 20 cars off the road as members sell their rides or decide not to buy new ones.” Each move to cloud computing makes some or all of organizations unique servers, storage devices, and applications obsolete.

The trend: With the transportation market, the future will be “a blend of things like the Zipcar, public transportation, and private car ownership (according to Bill Ford), and with the IT industry, the future will be a combination of cloud computing, managed services, and in-house IT service provision.

Zipcars and cloud computing are benefiting from the new shared services model driven by cost-savings, flexibility, efficiencies of allotment, and eco-consciousness. These are driving change in our usage of transportation and computing for the better.
