Classroom Ideas Write On! It irritated his fellow writers to no end, as they labored over each sentence while their publication deadlines loomed. Indeed, the overwhelming majority of us often have difficulty with writing at one time or another.
Other Extensions Introduction The Common Lisp standard allows considerable latitude in the details of an implementation, and each particular Common Lisp system has some idiosyncrasies.
This chapter describes ordinary user-level features of Clozure CL, including features that may be part of the Common Lisp standard, but which may have quirks or details in the Clozure CL implementation that are not described by the standard.
It also describes extensions to the standard; that is, features of Clozure CL that are not part of the Common Lisp standard at all. Memory-mapped Files In release 1. On operating systems that support memory-mapped files including Mac OS X, Linux, and FreeBSDthe operating system can arrange for a range of virtual memory addresses to refer to the contents of an open file.

I'm even throwing something together I hope to both use in a class I'm developing as well as it being the basis of a book of tutorials on Behavior Driven Development in Ruby.
As long as the file remains open, programs can read values from the file by reading addresses in the mapped range. Using memory-mapped files may in some cases be more efficient than reading the contents of a file into a data structure in memory.
Clozure CL provides the functions map-file-to-ivector and map-file-to-octet-vector to support memory-mapping. These functions return vectors whose contents are the contents of memory-mapped files. Reading an element of such a vector returns data from the corresponding position in the file.
Without memory-mapped files, a common idiom for reading the contents of files might be something like this: The vectors returned by map-file-to-ivector and map-file-to-octet-vector are read-only; any attempt to change an element of a vector returned by these functions results in a memory-access error.
Clozure CL does not currently support writing data to memory-mapped files. That means that you cannot use these functions to create a vector longer than array-total-size-limit, even if the filesystem supports file sizes that are larger.
The value of array-total-size-limit is expt 2 24 on but platforms; and expt 2 56 on bit platforms. If successful, it returns a read-only vector whose element-type is given by element-type, and whose contents are the contents of the memory-mapped file. Specified as a type-specifier that names a subtype of either signed-byte or unsigned-byte.
Given a displaced array like the value returned by map-file-to-ivectorthe function array-displacement returns the underlying array and the displacement index in elements. Currently, Clozure CL supports only read operations on memory-mapped files. If you try to change the contents of an array returned by map-file-to-ivectorClozure CL signals a memory error.
The value of a static variable is thus the same across all threads; changing the value in one thread changes it for all threads. Static variables are shared global resources; a dynamic binding is private to a single thread.
Static variables therefore provide a simple way to share mutable state across threads. They also provide a simple way to introduce race conditions and obscure bugs into your code, since every thread reads and writes the same instance of a given static variable.
You must take care, therefore, in how you change the values of static variables, and use normal multithreaded programming techniques, such as locks or semaphores, to protect against race conditions. In Clozure CL, access to a static variable is usually faster than access to a special variable that has not been declared static.
Marks the variable static, preventing any attempt to dynamically rebind it. Any attempt to dynamically rebind var signals an error.
Saving Applications Clozure CL provides the function save-applicationwhich creates a file containing an archived Lisp memory image. Clozure CL consists of a small executable called the lisp kernelwhich implements the very lowest level features of the Lisp system, and a heap imagewhich contains the in-memory representation of most of the Lisp system, including functions, data structures, variables, and so on.
When you start Clozure CL, you are launching the kernel, which then locates and reads an image file, restoring the archived image in memory. Once the image is fully restored, the Lisp system is running.
If you later pass your image file to the Clozure CL kernel as a command-line parameter, it then loads your image file instead of its default one, and Clozure CL starts up with your modifications.Recursion A recursive function, as you saw in CS, is one that calls itself.
Classic textbook example: factorial Mathematical deﬁnition: 0! = 1 N! = N (N 1)!ifN > 0 How would you implement this?
CS — R ECURSION 1 mathematical entity.! Good recursive solutions may . Recursive programming is the process of progressively reducing a problem in to easier to solve versions of itself.
Every recursive function tends to: take a list to process, or . Developing successful writing teachers: Outcomes of professional development Project model that stresses writing as a recursive process, and encourages instruction in the development of fluency, form, and mechanical accuracy (Blau, ); (b) group Generally, effective writing instruction should make connections to children’s lives.
The genre of writing about writing can be approached in various ways – from a process paper to sharing personal experience. The elements that go into this specific genre include answers to the five most important questions who, what, where, and why they write.
Writing is not a linear process, but a recursive one, and students should know that – Hitchens aside – all writers go through these same stages, and all writers occasionally struggle with their writing. A Guide to Writing Mathematics Dr.
Kevin P. Lee Introduction This is a math class! Why are we writing? The process of writing will help you learn and retain the concepts which you will be exploring in your math class. 1. What does good mathematical writing look like?
As you learn more math, being able to express mathematical ideas will.
