  • Photo Tampering Throughout History Photography lost its innocence many years ago. In as early as the 1860s, photographs were already being manipulated, only a few decades after Niepce created the first photograph in 1814. With the advent of high-resolution digital cameras, powerful personal computers and sophisticated photo-editing software, the manipulation of digital images is becoming more common. Here, I have collected some examples of tampering throughout history. To help contend with the implications of this tampering, we have developed a series of tools for detecting traces of tampering in digital images (contact me at Ma'at Consulting for more information about our services). circa 1860: This nearly iconic portrait of U.S. President Abraham Lincoln is a composite of Lincoln's head and the Southern politician John Calhoun's body. Putting the date of this image into context, note that the first permanent photographic image was created in 1826 and the Eastman Dry Plate Company (later to become Eastman Kodak) was created in 1881. circa 1865: In this photo by famed photographer Mathew Brady, General Sherman is seen posing with his Generals. General Francis P. Blair (far right) was added to the original photograph.

Taking the Information Plunge With Tinderbox | Mac.AppStorm - 146 views

  • Tinderbox “the tool for notes.”
  • The power of Tinderbox comes from its ability to display those notes in a number of different and helpful ways, and its array of mechanisms for manipulating those notes.
  • Tinderbox is a toolbox full of tools that let you play with information. DevonThink Pro is a better tool for research, particularly when linked with Devon Agent, OmniOutliner is a better outliner, Scrivener is a better writing tool, and Omnigraffle does a better job of drawing. All of these tools are great, but while they overlap some, they don’t cover everything Tinderbox does.
  • ...4 more annotations...
  • For many years, I have walked into large, complex businesses and attempted to identify what was going on and how it could be done better. My job was part Qualitative Research, part Quantitative Research, and part Political Analysis. Qualitative Research has a number of tools for analyzing interviews and playing with the data, teasing meaning out of diverse viewpoints. I used these tools effectively, but I wish I’d had Tinderbox earlier in my career because it would have made this job easier. Tinderbox is a far more useful tool for ‘right-brained’ qualitative analysis than most of the other tools I’ve worked with, but even that sells it short.
  • Very few people I’ve seen truly understand its character as a tool box for manipulating and exploring information.
  • I have been using TB for just over a year and it has become my second top application after Scrivener. (I also use DEVONThink Pro) I have planned a trilogy of novels on it, and a detailed timeline for the first novel. I’m currently editing the first novel, which is to come out in Feb 2112, and I have set up my Scrivener screen so that the timeline occupies the lower third of my screen (though the Apps can be viewed together in other ways).
  • As for the trilogy, the plan is a work in progress using map view. But the power to manipulate the characters, events and relationships, and run what-ifs, has far exceeded my expectations.

    Few people enter the teaching profession because they are passionate about controlling behaviour or disciplining prospective pupils. Most become educators because they want to make a positive difference in students' lives. However, countless well-intentioned yet potentially ill-prepared teachers find themselves in situations during the school year where they feel compelled to use forms of intimidation, manipulation, bribery, yelling, scolding, or even false praise to make students behave. These archaic classroom management techniques often backfire- as they did for me early in my teaching career-and result in students losing respect for and disliking the teacher.

    "Schools are inherently full of different characters. With a mix of personalities, students and staff can often clash with each other, using different strategies to gain the upper hand, or simply to avoid conflict and live a quiet life. Yet, there are those characters who can be sneaky, back-stabbing, manipulative or darn right confrontational. It's these people who know how to play politics to win friends, influence and possibly to gain the upper hand in climbing the next step on the career ladder."

    by Stevina Evuleocha, Steve Ugbah California State University Abstract The quest for an ideal medium to deliver business content to Gen Y learners has led instructors to consider the Internet, since digital content that exists in databases can be manipulated by a range of programming services (Shim et al., 2006). Shim et al., have also asserted that web development has been hampered by bandwidth and difficulties of "back end integration," consequently, impacting the presentational aspects of data and user interfaces (Yang & Tang, 2005). Innovations in computer and software technologies appear to have ameliorated the technical difficulties, resulting in the emergence of new media such as podcasting, webcasting, videostreaming, blogging, and Synchronized Multimedia Integration Language (SMIL) technologies (Shim, 2002). These new media streams can be integrated into traditional lectures, thus enhancing the educational environment (McLaughlin, 2006), particularly for Gen Y learners. This paper discusses the efficacy of podcasting in business education, reviews the characteristics of Generation Y (Gen Y) learners, discusses learning styles and theories that support mobile learning, reviews learning styles of Gen Y learners, and discusses whether adaptations are necessary to address the updated needs of this new generation of learners in the business communication context.

    "Vous l'avez certainement remarqué, en ce moment beaucoup de professionnels de l'information migrent de Delicious à Diigo. Effet de mode ou véritable révolution? Pour tenter de le savoir, je vous propose un comparatif qui, je l'espère, vous aidera à choisir entre l'une ou l'autre des plateformes. Delicious et Diigo fonctionnent sur le même principe: ils vous permettent d'enregistrer vos favoris en ligne. Jusque-là tout va bien : la manipulation se fait en quelques clics que ce soit avec l'un ou avec l'autre. Mais une fois que l'on a créé et les favoris importés, on se retrouve dans deux univers très différents. diigo Diigo: réseau social ou l'outil de travail ? Dès la page d'accueil on trouve une ressemblance très forte avec les sites de réseaux sociaux: un profil avec vos informations personnelles, vos activités récentes ainsi que celles de vos amis. Car dans Diigo, vous avez des amis, avec qui vous pouvez converser et travailler en groupe. Le plus ? Le travail en commun permet en autre de créer une liste fermée de mots-clés pour indexer vos favoris., ce qui évite les listes de tags interminables et peu pertinentes. L'organisation des mots-clés par liste thématique peut s'avérer utile notamment lorsque l'on souhaite créer une liste de signets pour le public de la bibliothèque. Le moins ? Il faut bien dire qu'on a du mal à distinguer le véritable enjeu du site, tant le coté social est présent. Par exemple il est possible d'échanger ses idées, ses favoris ou ses annotations avec des inconnus de la communauté via les forums thématiques.

  • We tend to think of fractals in computational terms, because in general we generate fractal images using digital computers. But you don’t need to. Fractals are actually fascinatingly ubiquitous, and you can produce them in lots of different ways – not just digitally.

    "In this video, what they've done is set up three screens, in a triangular pattern, and set them to display the input from a camera.. If you watch, they're able to manipulate it to get Julia fractals, Sierpinski triangles, and several other really famous fractals. "

  • to educators, I ask, if you are not teaching these things in your classes, why are you not?
  • 1. How to predict consequences
  • The prediction of consequences is part science, part mathematics, and part visualization. It is essentially the ability to create a mental model imaging the sequence of events that would follow, "what would likely happen if...?"
  • ...18 more annotations...
  • 2. How to read
  • how to look at some text and to understand, in a deep way, what is being asserted (this also applies to audio and video, but grounding yourself in text will transfer relatively easily, if incompletely, to other domains).
  • 3. How to distinguish truth from fiction
  • Do not simply accept what you are told. Always ask, how can you know that this is true? What evidence would lead you to believe that it is false?
  • 4. How to empathize
  • this will allow other people to become a surprising source of new knowledge and insight.
  • 5. How to be creative
  • Sometimes people think that creative ideas spring out of nothing (like the proverbial 'blank page' staring back at the writer) but creativity is in fact the result of using and manipulating your knowledge in certain ways.
  • creativity involves a transfer of knowledge from one domain to another domain, and sometimes a manipulation of that knowledge.
  • pattern recognition can be learned
  • 6. How to communicate clearly
  • 7. How to Learn
  • Learning to learn is the same as learning anything else. It takes practice.
  • 8. How to stay healthy
  • 9. How to value yourself
  • You can have all the knowledge and skills in the world, but they are meaningless if you do not feel personally empowered to use them; it's like owning a Lamborghini and not having a driver's license.
  • 10. How to live meaningfully
  • When you realize you have the power to choose what you are doing, you realize you have the power to choose the consequences. Which means that consequences -- even bad consequences -- are for the most part a matter of choice
