What is the role of the driver in a pair programming setting quizlet?
What is the role of the driver?
driver is doing the programming and a running spoken narrative of what they are doing and why. -Pair programming produces higher quality code and it produces it faster.
What is the role of a navigator in a pair programming setting?
The navigator is reviewing the code as it is being written, given their opinion to the driver. They are also keeping track of all the loose ends, the minutia that can easily fall through the cracks when one developer is working alone.
What do you do in pair programming?
Below I take a look at 6 steps to keep in mind for more pleasant and effective pair programming sessions.
Prepare. To prepare for the session, take the following steps: Work closely together. Learn and facilitate learning. Establish a rhythm. Communicate effectively. Embrace challenges.
What are the advantages of pair programming?
The Pros of Pair Programming
Fewer mistakes and bugs. Software developers usually work alone, which can cause negative traits like stubbornness and tunnel vision.
Greater resiliency. The ?bus factor? should be a concern for all mature software development teams.
Increased code quality.
Improved team morale.

Why pair programming is bad?
Pair Programming gives that feeling of someone looking over your shoulder while you work. It can reignite the Imposter Syndrome which so many Software Developers experience when they feel like they should be able to do something which they can?t.
What is the definition of a navigator in pair programming?
Navigator: -Dictates the code that is to be written ? the ?what? -Clearly communicates what code to write. -Explains ?why? they have chosen the particular solution to this problem.
Which one is true for pair programming?
Pair programming is quicker, better quality, cheaper, and less effort than solo programming B. The Driver works on tasks at hand, the Observer thinks strategically about future tasks C. A pair will eventually figure out who is the best driver and who is the best observer, and then stick primarily to those roles D.
Which is not the benefit of pair programming?
The Disadvantages of Pair Programming Pair programming has benefits, but it?s not a panacea, and it?s not for everyone. Higher Costs It follows logically that two developers using one keyboard multiplies development costs. Studies have shown a 15% ? 100% increase in baseline development costs.
Who are the drivers and navigators in pair programming?
These roles are commonly known as the ?driver?, who is the programmer currently in control of the keyboard, and the ?navigator?, who contributes to the task verbally and by other more subtle means (see Bryant et al., 2006a ).
What?s the role of the driver in a pair?
In a pair, we have a driver and a navigator. Think of these roles as they are in driving rally. The driver is hands on the wheel, and in control of paying attention to the immediate task at hand. They are busy looking at the road ahead, optimizing the drive and not checking the map.
Which is the best description of pair programming?
Pair programming is an agile software development technique in which two programmers work together at one workstation. One, the driver, writes code while the other, the observer or navigator, reviews each line of code as it is typed in. The two programmers switch roles frequently.
What is the role of the observer in pair programming?
One, the driver, writes code while the other, the observer or navigator, reviews each line of code as it is typed in. The two programmers switch roles frequently. While reviewing, the observer also considers the ?strategic? direction of the work, coming up with ideas for improvements and likely future problems to address.
What is the role of the female wolf spider?
While it was once thought that female spiders were more or less passive when it came to courtship and mating, a new paper titled ?Are you Paying Attention?
Female Wolf Spiders Increase Dragline Silk Advertisements When Males do not Court? finds that not only do female wolf spiders play an active role in attracting a ?
How do you tell if a wolf spider is a female?
Determining the gender of mature wolf spiders is relatively easy to do by looking for the presence of enlarged pedipalps or ?boxing gloves? on males. Spiders have an additional set of appendages, attached just behind the mouth parts, called pedipalps.
Which is bigger male or female wolf spider?
They exhibit four small anterior and four large posterior eyes (Barth, 2002). Wolf spiders usually have low to moderate sexual size dimorphism, but, as is general for spiders, females are larger than males (Walker and Rypstra, 2003; Logunov, 2011).
How big can a female wolf spider get?
Its body can measure more than one-inch long (and the whole spider can measure 4 inches across, from legs to legs). Female wolf spiders are larger than males; their undersides are solid black. Because some wolf spiders are large and hairy, they are sometimes mistaken for tarantulas.
How are wolf spiders not dangerous to humans?
Wolf spiders are venomous but not poisonous. That means that they inject their venom into their prey in order to paralyze it. Wolf spiders are not necessarily particularly dangerous to humans since the amount of venom they can administer is not enough to jeopardize your health.
Is the wolf spider bite more dangerous than a bee sting?
Generally speaking, a wolf spider bite is no more dangerous or painful than a bee sting. Typical reactions to a wolf spider bite include initial pain and redness, but both symptoms gradually subside in most people. In fact, medical histories hold no records of serious consequences resulting from a wolf spider bite.
How are wolf spiders different from other spiders?
In general, wolf spiders are quite aggressive, but usually towards their prey rather than humans. In most cases, when they sense a threat, wolf spiders will retreat rather than put up a fight. However, when cornered and out of options, wolf spiders won?t hesitate to bite you. What do Wolf Spiders Bites Look Like
Wolf spiders come in contact with female wolf spiders during the mating season. These spiders are highly venomous, which means they kill their prey with the venom present in their body. The venom of a wolf spider is enough to paralyze their prey.
