Jan. 19, 1983: Apple Gets Graphic With Lisa | This Day In Tech

applelisa1983102634506fclg1983: Apple releases the Lisa, the first commercial computer with a graphical user interface (GUI) — the advance that would finally make computers usable by people with no special training. It doesn’t sell well, but it does get Apple on the right development track, sparks the first of many brawls with perpetual rival Microsoft, and sets in motion the animus between Steve Jobs and John Sculley that would frame the company’s history for a decade.

Sure — you’re all fancy now with that multitouch iPhone. You wiggle and writhe like an idiot to operate your Nintendo Wii. Maybe you’ve got your eye on a breath-controlled laptop — because using a mouse to work on your computer is so 20th-century. But you owe it all to one of Apple’s earliest and most magnificent failures.

Apple revolutionized computing with the Macintosh of “1984″ TV-ad fame — the world’s first affordable GUI computer. But a year earlier Lisa set the stage. It was one of the company’s most glorious missteps, one without which the Mac may not have succeeded as dramatically as Lisa had failed.

“The Lisa was doomed because it was basically a prototype — an overpriced, underpowered cobbled-together ramshackle Mac,” Cult of Mac author (and former Wired.com editor) Leander Kahney said in an e-mail interview. “Lisa taught the Mac team they’d need to articulate a clear purpose for the Mac.”

Apple spent $150 million developing Lisa but sold only 10,000 of them in a world dominated by cheaper IBM desktops. With an outrageous price tag of $10,000 (more than $21,000 in today’s leaf), the Lisa’s built-in calculator could tell you Apple lost a lot of money.

Lisa’s specs were improved and the price cut in half, but the plug was pulled in only three years. And — oh yeah — Apple co-founder Jobs got kicked off the Lisa team by CEO John Scully and went to another project. The Macintosh. See above. Jobs, of course, would be pushed out by Scully in 1985 only to get his revenge by returning the favor 10 years later.

Before Lisa — the name was the acronym for “Local Integrated Software Architecture” and possibly the daughter of someone on the development team (Jobs had a daughter names Lisa) — the only user interface was the command line, the only input was a keyboard, and the only display was some lines of off-white text on a black screen. Microsoft’s somewhat approachable DOS (Disc Operating System) had been around for a couple of years, but that only simplified the command set, not the input technique.

Lisa changed all that. Its screen displayed little pictures — icons. Moving the mouse on your work surface moved a cursor in a spatially equivalent way on the screen. When your cursor hovered on an icon you clicked a soon-to-be-iconic one-button mouse, and a program would start, as if by magic.

Not so magical was the dearth of software for Lisa, which was not compatible with any other computer in the world. Lisa shipped with seven programs, and not much else got written for it during its brief stint in the Apple product line, which (price aside) contributed to its lack of traction.

Though Lisa was first to market, the GUI was not exactly an Apple innovation. Jobs got a look at the very first computer with a graphical user interface during a tour of the storied Xerox PARC lab. This was a turning point, according to invention historian Mary Bellis: Even though work on Lisa had already begun, Jobs would hire several PARC engineers to join the Lisa (and later Mac) team.

Apple sued when Microsoft released Windows 1.0, arguing that its once and future nemesis had stolen the “look and feel” of Lisa’s OS. According to Andy Hertzfeld, who says he witnessed an exchange between Jobs and Bill Gates at the 1983 Comdex industry trade show, the Microsoft co-founder expressed the nuanced view that both companies had stolen the idea — from PARC.

From Hertzfeld’s account:

“You’re ripping us off!” Steve shouted, raising his voice even higher. “I trusted you, and now you’re stealing from us!”

But Bill Gates just stood there coolly, looking Steve directly in the eye, before starting to speak in his squeaky voice.

“Well, Steve, I think there’s more than one way of looking at it. I think it’s more like we both had this rich neighbor named Xerox, and I broke into his house to steal the TV set and found out that you had already stolen it.”

Xerox itself had an early incarnation of a machine that had some GUI functionality — the Star — and Lisa’s developers said they were informed by that less-than-successful commercial attempt, to a point. In an interview with Byte in October 1982, three months before the Lisa came out, Wayne Rosing, Bruce Daniels and Larry Tessler were asked about the Xerox Star:

BYTE: Do you have a Xerox Star here that you work with?

Tesler: No, we didn’t have one here. We went to the NCC when the Star was announced and looked at it. And in fact it did have an immediate impact. A few months after looking at it we made some changes to our user interface based on ideas that we got from it. For example, the desktop manager we had before was completely different; it didn’t use icons at all, and we never liked it very much. We decided to change ours to the icon base. That was probably the only thing we got from the Star, I think. Most of our Xerox inspiration was Smalltalk rather than Star.

BYTE: What does Lisa have that the Star doesn’t have?

Tesler: We’re talking about graphics capability. You originally asked why we didn’t use graphics hardware. Our graphics primitives in software are more general than the Star’s, so they perform better. We have a faster and more general ability to draw on the screen a picture of multiple graphical objects in different shapes, to have one window that uncovers another, and to repaint just the parts that are uncovered.

Daniels: Look at the desktop managers of the Star and Lisa. With the Star, you can only put them at fixed places on the screen so you know they don’t ever overlap. On ours, you can put them any place you want. It’s that generality that allows I us to have arbitrarily shaped things I and covering each other up and…

BYTE: Documents or forms, shapes, or anything…

Daniels: Yes.

Tesler: Right. We have curves in it. Everything in the Star, you’ll notice, is really rectangular, and our things can have curved edges and that sort of thing.

Apart from some specialized contexts GUIs are the norm now in computing. Microsoft has considerably more copies of its GUI in customer hands than Apple — yet another instance of the first to market not becoming the dominant player. And while it would be Mac that captured the public’s imagination, he might not have had quite the swagger without lessons he learned from his awkward older sister.

“Although it was a technical and commercial flop, Lisa was important because it was the progenitor of the Mac,” says Kahney. “Apple screwed up the Lisa, but without it, there would be no Macintosh.”

Why Have A Social Media Policy Anyway? Take 2 #edchat #edtech

Coming up with a social media policy would take a huge amount of thought and time. It would also have to be constantly updated. But, can we afford to be without one? http://amplify.com/u/1fo5

Selling Lesson Plans Online, Teachers Raise Cash and Questions

Between Craigslist and eBay, the Internet is well established as a marketplace where one person’s trash is transformed into another’s treasure. Now, thousands of teachers are cashing in on a commodity they used to give away, selling lesson plans online for exercises as simple as M&M sorting and as sophisticated as Shakespeare.

Skip to next paragraph

Ruby Washington/The New York Times

Erica Bohrer, a teacher on Long Island, said that selling her lesson plans gave her a chance to receive credit for her hard work.

Ruby Washington/The New York Times

Erica Bohrer has used earnings from selling her lesson plans to buy books for students and to help with her mortgage payments.

Ruby Washington/The New York Times

Ms. Bohrer has sold 31 M&M counting exercises, which come with directions, sorting mats and work sheets, for $3 each.

Readers' Comments

Readers shared their thoughts on this article.

While some of this extra money is going to buy books and classroom supplies in a time of tight budgets, the new teacher-entrepreneurs are also spending it on dinners out, mortgage payments, credit card bills, vacation travel and even home renovation, leading some school officials to raise questions over who owns material developed for public school classrooms.

“To the extent that school district resources are used, then I think it’s fair to ask whether the district should share in the proceeds,” said Robert N. Lowry, deputy director of the New York State Council of School Superintendents.

The marketplace for educational tips and tricks is too new to have generated policies or guidelines in most places. In Fairfax County, Va., officials had been studying the issue when they discovered this fall that a former football coach was selling his playbook and instructional DVDs online for $197; they investigated but let him keep selling.

A high school English teacher in upstate New York said her bosses barred her from selling plans used in her classroom; she spoke on the condition that she not be named.

Beyond the unresolved legal questions, there are philosophical ones. Joseph McDonald, a professor at the Steinhardt School of Culture, Education and Human Development at New York University, said the online selling cheapens what teachers do and undermines efforts to build sites where educators freely exchange ideas and lesson plans.

“Teachers swapping ideas with one another, that’s a great thing,” he said. “But somebody asking 75 cents for a word puzzle reduces the power of the learning community and is ultimately destructive to the profession.”

Teachers like Erica Bohrer, though, see the new demand for lessons as long-awaited recognition of their worth.

“Teaching can be a thankless job,” said Ms. Bohrer, 30, who has used the $650 she earned in the past year to add books to a reading nook in her first-grade classroom at Daniel Street Elementary School on Long Island and to help with mortgage payments. “I put my hard-earned time and effort into creating these things, and I just would like credit.”

The humble lesson plan has gained value as focus on testing and individualized instruction has increased. At the same time, the Internet has diminished the isolation of classroom teachers. Just about every imaginable lesson for preschool through college is now up for sale — on individual teachers’ blogs as well as commercial sites where buyers can review and grade the material.

Teachers Pay Teachers, one of the largest such sites, with more than 200,000 registered users, has recorded $600,000 in sales since it was started in 2006 — $450,000 of that in the past year, said its founder, Paul Edelman, a former New York City teacher. The top seller, a high school English teacher in California, has made $36,000 in sales.

Another site, We Are Teachers, went online last year with a “knowledge marketplace” that includes lesson plans and online tutoring.

Kelly Gionti, a teacher at the High School for Law, Advocacy and Community Justice in Manhattan, has sold $2,544 worth of unit plans for “The Catcher in the Rye” and “The Great Gatsby,” among others, helping finance trips to Rome and Ireland, as well as class supplies.

Margaret Whisnant, a retired teacher in North Carolina, earns an average of $750 a month from lessons based on her three decades of teaching middle school classics like “The Outsiders,” enough to pay for new kitchen counters and appliances.

“I have wanted to redo my kitchen for 20 years, and I just could not get the funds together,” she said. “Well, now I’m going to have to learn to cook.”

Lisa Michalek, 40, who taught for six years in Rochester and now works for Aventa Learning, a for-profit online education company, said she spent about five hours a week tweaking old lesson plans and creating new ones, like an earth science curriculum that sells for $59.95.

“I knew I had good lessons, so I thought, ‘Why not see what other people think of it?’ ” Ms. Michalek said.

After $31,000 in sales, she has her answer. Alice Coburn, 56, a vocational education teacher in Goshen, N.Y., said she saved two to three hours each time she downloaded Ms. Michalek’s PowerPoint presentations instead of starting from scratch. “I hate reinventing the wheel,” Ms. Coburn said.

Others find comfort in having a class-tested lesson by a more experienced teacher. Lauren Perreca, 24, used a $10 lesson on the Vietnam War novel “Fallen Angels” as a reference last year while creating her own lesson for her classes at Weston High School in Connecticut. She also revised her reading questions about “Lord of the Flies” after comparing them with two other lesson plans.

“At first I was self-conscious I had bought something, because what did that say about me?” she said. “But I realized I wasn’t just taking it and using it, I was adapting it to fill in the gaps of my knowledge.”

Now Ms. Perreca has started selling her own lesson plans, like a 54-page “Macbeth” unit with quizzes and homework assignments ($10) that she wrote in graduate school. She said she spent $140 of her $523 in earnings on cookies and books for her students, and used the rest to splurge on dinners out that she could not otherwise afford.

Her students are incredulous. “They’re like, ‘Who would want to buy those? They’re so boring,’ ” Ms. Perreca said. “I’m like, ‘Hey, I’m making money.’ ”

In Ms. Bohrer’s class the other day in Lindenhurst, N.Y., five children were counting M&Ms while she made sure they digested the lesson before the candy. The exercise, which comes with directions, sorting mats and work sheets, has sold 31 times for $3 a pop. A variation with Lucky Charms is popular around St. Patrick’s Day, she said.

“M&M sorting is not a new concept,” said Ms. Bohrer, who has been teaching since 2001. “I made it easier for teachers to do. They just have to click and print.”

Daniel Street’s principal, Frank Picozzi, said he supported Ms. Bohrer’s online business because his students reaped the benefits of her initiative and creativity.

Ms. Bohrer recalled that when she used to share her lesson plans at no charge, a poster of her reading strategies was passed around so many times that it ended up with a teacher in another school who had no idea where it came from.

“I’ll share with friends,” Ms. Bohrer said, “and if anyone else likes it, I’ll tell them where to buy it.”

Educators and the Great Twitter Controversy?

This post is part of a series tagged Education News and Controversy
news and controversy

Professionals in the field of education are using Twitter more than ever to share ideas and promote their businesses. My online publishing work has benefitted from two social media networks in particular. Using Twitter and Facebook to announce my writing has brought more readers and in turn, wider exposure and more relevant leads for my advertisers.


People in some corners have mixed attitudes about social media. Obviously I am a proponent for the profit it brings my online publishing. At the same time, I am old fashioned in some ways and I understand their position. In a nutshell, they seem to feel Twitter and Facebook are places where educators “play” and “get too personal.” Because we are public servants, or for some other unknown reason, they feel educators have no business using these services. I think they are correct that should we set a higher standard of we publish online but they are not correct that educators can do no good on social media.

I have also made many contacts with educators and their ideas. I imagine a world where restaurant managers communicate on how to eliminate watse-age on their bottom line. I see waiters finding a place to vent and become better at what they do. I see people who ffrequent Vegas finding tips and deals from people on their Twitter list.

Why should we as educators fear connecting on Twitter? It has such great potential to help us teach better.

Connecting on Twitter has all served to make me a more effective and accomplished teacher. You may be asking yourself: “By who’s evaluation are you better?” Well, first by my own but also by standardized test score results and continued recognition through the contractual terms of my job as a teacher. Then, there are the comments I have recieved that show me my work is having a positive impoact on classroom across the country. This is because of Twitter along with my blog and at times Facebook.

To those out there who have taken their Twitter down because of these fears or hesitated to start an account, I give you this advice:

In my opinion, there is likely nothing inherently dangerous to your job about a Twitter account if you are positive and you consider the people who are reading your tweets when you do so.

Having said that, some teachers who feel the need to post their drunk pictures in Mexico on a wild weekend (for example), I am not defending that sort of stupidity and irresponsibility. What’s your take on educators and the Twitter controversy?

As a footnote, Karen Schweitzer, a guest blogger here, has featured a list of 15 Teachers worth following on Twitter. Please feel free to add them and see what value they add to your profession and passion. I’m finding more from various sources every month or so. If you would like to be featured, leave a comment, send me an email: damien [at] rileycentral [dot] net, or send me a message on Twitter [at] rileycentral and I will check out your tweets.

Educational Conformity & Social Networking: Improving the Conversation - Synthesizing Education Blog

Educators are beginning to see the value of social networking with emphasis on sites and platforms like Facebook, Twitter, and Nings. This is all for the betterment of our practice, but we must also be mindful that conforming our ideas to those who we have discussions with is not always improving education or an effective use of these social platforms.

I notice a lot of this type of behavior in education circles on Twitter and blogs. Obviously, I am not advocating for us to kick and scream like five year olds when another individual’s beliefs don’t align with our own. What I am saying is that we need to hold strong to our deepest beliefs while searching for answers and maintaining an open mind that will make all of our ideas better. Rather than drawing a “line in the sand”, it makes more sense for us to engage in more conversation that hi lights the positives of both belief systems and then creates a comprehensive answer out of these positives through integrative thinking.

Allowing for our own belief system to be jeopardized in virtual environments does not improve the conversation or bring new ideas to the table. Altering ourselves completely to attract more followers or gain friends in social networking sites is detrimental to the very reason we have all come together. On the opposite side of the conformist mentality is that of which the individual will not bend at all or engage in conversation.

If you hold strong to a vision or belief, then consider the opposing side and attempt to relate your knowledge and research to his or hers. At some point, we all need to realize that being right is not based on the degree we have earned, years of experience, or books that we have read. Much of this comes with realizing that no one’s system is perfect. Educators who maintain a traditionalist mentality where students should sit in rows, be talked at, and lack any kind of engagement need to realize that they are antiquated and should move on with life to another profession. Futurists who think that technology is the savior of all problems in education and kids will learn simply by placing their hands on a machine and absorbing information through osmosis need to realize they are out of touch as well. Regardless of how these two groups feel about each other, it is important that we are all conversing and articulating our rationale for our belief system. In the end, our goal should be to improve education; not promote our individual belief system so we can claim victory.

P.S. Agreeing with me on this post does not label you as a “conformist”. Does it?

12 Inspiring Visual Search Engines | TECHTIFIED

12 Inspiring Visual Search Engines

We all know that a picture is worth a thousand words. Beyond the usual lines of text and blue links, visual search engines can present results and relationships that are more quickly grasped, as well as flexible ways to browse and explore. As the web becomes increasingly image- and video-based, it just makes sense to scan certain results visually.

Here are 12 visual search engines, each providing a different set of benefits we enjoy. Hopefully you’ll find a few that will come in handy in your next search…

Spezify

Search Spezify for a Flash-based mixed-media visual collage of results. Spezify also helps you focus your search with hot searches and related words. Drawing equally from blogs, videos, images, music, tweets, and more, Spezify gives a diverse overview of any given subject that is useful and fun to navigate.

Cooliris

The Cooliris plugin transforms searches across Google Images, Bing, Flickr, Hulu, YouTube, Amazon and others into a beautiful, interactive 3D wall. It’s a fast way to browse images and video, for shopping, entertainment, and beyond. Results can be enlarged, saved, shared, and played within the application.

SpaceTime

Originally a 3D browser, SpaceTime is now a visual search engine. Using Flash, you can browse a “cover flow” sequence of results from Google, Images, Wikipedia, or YouTube. You can’t play videos within search results, but it’s a handy way to identify the clip or scene you’re looking for.

Jinni


With many visual search engines, the innovation starts with the way results are presented. With Jinni, a search engine for movies and TV shows, the innovation starts when you type in your search. Jinni’s semantic engine takes a flexible, mood-based approach. Type a search or visually browse categories like “suspenseful” and “psychological.” Results are displayed as a picture collage of screen stills, sized by relevance. Pop-up windows provide more information and direct you to watch your chosen movie or show.

Viewzi

Viewzi’s highly customizable search engine and plug-in offers sixteen different ways to view results for any given search. Once you get a feel for the options, you can start to take advantage of the level of control over both display and sources.

NeXplore

NeXplore offers three ways of viewing search results (summary with pop-up previews, gallery, and line) but also lets you easily focus your search on blogs, podcast, videos, news or images as well as web. It’s also easy to share, save sites for later or trash results you don’t like.

EyePlorer


EyePlorer is a search engine for facts – a handy research tool. Type or drag your search term into the central search box, and the circle fills up with grouped, related concepts. From there, click on topics to get more information. You can also add topics to see combined results, or save topics temporarily on the notepad.

Quintura


Quintura’s search widget creates an interactive tag cloud of related topics around a specific search term. Browse the cloud to explore a topic visually and find more information.

LivePlasma

LivePlasma’ results for music and movies are a visual map of relationships between artists and works. You can’t listen or watch on the website, but it’s an unusual way to get ideas of new bands and movies to try based on your existing interests. Sign up to save your favorite maps.

Ujiko

Ujiko’s visual search engine displays results in a circle, clustered by color. Point your mouse to a site and a preview appears in the center. You can label any site as “put this site forward” or “filter this site (dustbin)” to customize your results as you continue to refine your search.

Touchgraph

Touchgraph is more precisely a visualization tool (Java-based) for exploring connections between related websites. Enter a concept or website name to see a visual map and maybe also new websites of interest. The interactive Facebook Browser version shows connections between your Facebook friends, photos and locations.

Ziipa

Ziipa is a visual search engine for Web 2.0. Browse the tag cloud on the right-hand side or type a search, and results will be displayed as screenshots from the websites. Vote on websites to give them more prominence within the search results.
