7. The vi Editor

Andy Lester O'Reilly Media ePub

vi is the classic screen-editing program for Unix. A number of enhanced versions exist, including nvi, vim, vile, and elvis. On Mac OS X Tiger, the vi command is linked to vim. The Emacs editor, covered in Chapter 8, has several vi modes that allow you to use the same commands covered in this chapter.

The vi editor operates in two modes, command mode and insert mode. The dual mode makes vi an attractive editor for users who separate text entry from editing. For users who edit as they type, Emacs modeless editing can be more comfortable.

vi is based on an older line editor called ex . A user can invoke powerful editing capabilities within vi by typing a colon (:), entering an ex command, and pressing the Return key. Furthermore, you can place ex commands in a startup file called ~/.exrc, which vi reads at the beginning of your editing session. Because ex commands are still an important part of vi, they are also described in this chapter.

Chapter 16: Deal with Illegal and Awkward Interview Questions

Susan Britton Whitcomb JIST Publishing ePub

One of the basic causes for all the trouble in the world today is that people talk too much and think too little. They act impulsively without thinking. I always try to think before I talk.

—Margaret Chase Smith, American politician

Ever heard of The $64,000 Question? Debuting in the 1950s, this television quiz show was one of the earliest of the now-popular game show genre. The program became so popular that the saying, That’s the $64,000 question, has come to represent any question that is difficult to answer. Interviews are certainly loaded with $64,000 questions!

A sticky wicket is an allusion to an element of cricket and, never having played this British pastime, I’ll make my disclaimers for understanding the game fully. A wicket is a gate-like set of sticks with cross-pieces at which a ball is bowled. Wicket also refers to the turf between the wickets and, by extension, the condition of that turf. If the turf is waterlogged or muddy (not unusual for England), the ball behaves unpredictably and it is difficult to succeed...such turf is otherwise known as a sticky wicket.

Six Professional Development

Eric C. Sheninger Solution Tree Press ePub



For standards-based reform to work in science teaching and learning, teacher professional development needs to be sustainable, comprehensive, collaborative, and inquiry based. If possible, it should be embedded into the instructional day. It also needs to include a review of science concepts, particularly in the area of STEM, as well as methods to guide and assess student learning. Furthermore, it needs to address teachers’ fears and concerns about finding time to teach science and about their knowledge of the subject matter.

A main goal of professional development in science education is to strengthen teachers’ ability to design and teach effective, hands-on, inquiry-based lessons and create assessments that are authentic and multilayered. Since many teachers have never been exposed to scientific inquiry experiences, having them participate as learners in inquiry-based science provides them with the opportunity to understand learning from this perspective. In addition, the experience provides them with the opportunity to analyze their feelings as learners, discuss challenges from a teacher’s perspective, and increase their subject-matter knowledge. When modeling science teaching during staff development sessions, facilitators must continually pose the questions: What are we doing as teachers? Why?

A. Web Development Core Concepts

Jonathan LeBlanc Yahoo Press ePub

Why should we even consider using open source standards? This is a question that usually comes up when a company first begins embarking along the open source path, and its one of the most valid to ask before starting integrations.

Lets look at some of the benefits and drawbacks of open standards to help implementers decide if it is the correct approach for them.

The benefits are numerous, but well focus on just a few main points. Usually, open source initiatives that have any measure of success in the community have support from some major company. These companies often contribute heavily to the specifications and have a genuine business reason for doing so. In other words, these companies (e.g., Yahoo, Facebook, Google) are driving the future of the specification to fill some specific business need. This means that for the most part you, as an implementer, will be using a fully vetted specification that is geared toward improving that particular business need.
