SPLLIFT — Statically Analyzing Software Product Lines in Minutes Instead of Years

In this work, however, we show how an # e n d i f important class of existing inter-procedural static analyses can be # i f d e f G transparently lifted to SPLs. Without requiring programmers to y = foo (x); LIFT # e n d i f v o i d main () { change a single line of code, our approach SPL automatically i n t x = secret(); converts any analysis formulated for traditional programs within the print (y); } i n t y = 0; popular IFDS framework for inter-procedural, finite, distributive, y = foo (x); subset problems to an SPL-aware analysis formulated in the IDE i n t foo ( i n t p) { print (y); framework, a well-known extension to IFDS. -

The Oldest Rivalry in Computing Forget Apple Vs
Follow us on Twitter for more great Slate stories! Follow @slate BITWISE DECODING THE TECH WORLD. MAY 9 2014 9:57 AM The Oldest Rivalry in Computing Forget Apple vs. Google. Emacs and Vi have been battling for text-editor supremacy among programmers for 40 years. By David Auerbach An early Emacs manual cover from 1981. Courtesy of GNU Emacs n a world where both software and hardware frequently become obsolete right I on release, two rival programs can stake a claim to being among the longest-lived applications of all time. Both programs are about to enter their fifth decades. Both programs are text editors, for inputting and editing code, data files, raw HTML Web pages, and anything else. And they are mortal enemies. Their names are Emacs and Vi (styled by programmers as “vi”). These editors are legendary and ancient, no exaggeration. Both date back to at least 1976, making them older than the vast majority of people currently using them. Both programs are text editors, which means they are not WYSIWYG (what you see is what you get)—unlike, say, word processors like Microsoft Word, they do not format your words onscreen. Programming is very different from word processing, and the basic goal of Emacs and Vi—fast editing of source code (and any other text files)—has yet to become obsolete. Both have been in ongoing development for almost 40 years. These two wizened programs are as close to equally matched enemies as any two programs have ever been. If you know a programmer who uses one of them, there’s a good chance that she hates the other. -

UNIX Essentials (Hands-On)
UNIX essentials (hands-on) • the directory tree • running programs • the shell (using the T-shell) → command line processing → special characters → command types → shell variables → environment variables → wildcards → shell scripts → shell commands → pipes and redirection • OS commands • special files 1 • The Directory Tree → directories contain files and/or directories → / : means either the root directory, or a directory separator • consider /home/afniuser/AFNI_data3 afniuser/suma_demo → an "absolute" pathname begins with '/', a "relative" pathname does not • a relative pathname depends on where you start from • in the directories above, note which is a relative pathname → every directory has a parent directory • the relative pathname for the parent directory is '..' • the relative pathname for the current directory is '.' • consider './run_this_script' and '/bin/ls ../../suma_demo' → many commands can be used to return to the home directory (of "afniuser") • cd, cd ~, cd ~afniuser, cd $HOME, cd /home/afniuser • note the 2 special characters, '~' and '$' → while you work, keep your location within the directory tree in mind 2 → class work: • open a terminal window • commands: cd, pwd, ls, ls -al • use the "cd" command to go to the given directories e.g. for directory /usr/bin, use the command: cd /usr/bin once there, use the commands "pwd", "ls", and "ls -al" note that you can always return to the home directory via: cd / home/afniuser AFNI_data3 .. AFNI_data3/afni /usr/bin ~/abin ../../afniuser/../afniuser • first example (starting with the '/'directory), use the commands: cd / pwd ls ls -al 3 • Running Programs → a program is something that gets "executed", or "run" → the first element of a command line is generally a program (followed by a space) → most shells are case sensitive when processing a command → command examples: /bin/ls $HOME ~/AFNI_data3 count -digits 2 1 10 → script: an interpreted program (interpreted by another program) • e.g. -

Recompiling Minix
8 RECOMPILING MINIX This chapter is intended for those readers who wish to modify MINIX or its utili- ties. In the following pages we will tell what the various files do and howthe pieces are put together to form the whole. It should be emphasized that if you simply intend to use MINIX as distributed, then you do not have torecompile the system and you do not have toread this chapter.Howev er, ifyou want to makechanges to the core of the operating system itself, for example, to add a device driverfor a streamer tape, then you should read this chapter. 8.1. REBUILDING MINIX ON THE IBM PC Although this section is specifically for IBM PC users, it should also be read carefully by everyone interested in recompiling MINIX.Most of what is said here applies to all versions of MINIX.The sections about other processors mostly discuss the differences between recompiling MINIX on an IBM PC and on another system. The MINIX sources are contained in the following directories, normally all subdi- rectories of /usr/src except for include which goes in /usr/include: center allbox; l l. Directory Contents include The headers used by the SEC. 8.1 REBUILDING MINIX ON THE IBM PC 113 commands (has twosubdirectories) kernel Process, message, and I/O device handling mm The memory manager fs The file system tools Miscellaneous tools and utilities test Test programs lib Libraries (has several subdirectories) commands The utility programs (has manysubdirectories) Some of the directories contain subdirectories. If you are working on a hard disk, be sure that all these directories have been set up, and all files copied there from the dis- tribution diskettes and decompressed and dearchived. -

Text Editors for Programmers
Text Editors for Programmers Dr. Prasad Kulkarni Michael Jantz Jamie Robinson 1 Real Programmers 2 vim • Based on vi – vi written in 1976 and has become standard on Unix machines • Basic design principles: – Retains each permutation of typed keys to resolve commands – Smaller and faster editor ± but with less capacity for customization – Uses distinct editing ªmodesº 3 Using Vim on a Simple Example • You should have received two source files (simple.c and simple.h), a Makefile, and a dot_vimrc file from the lab website. – Save dot_vimrc as .vimrc in your home directory – Use mv to rename the file • mv dot_vimrc ~/.vimrc • “dot_vimrc” – A collection of vim commands run each time you start vim – Used to set mappings / options that are not otherwise set by default. 4 Using Vim to Create & Edit a File • Start a session – vim simple.c • Press 'i' to enter insert mode – Now type any text you want • 'Esc' to enter command mode – ':wq' to write changes and exit the session 5 Vim – Modes of Operation • Command Mode • Input Mode • Visual Mode V, v, ctrl - v Command Visual Escape Escape I, i, A, a, O, o, R, r Input 6 Essential Commands • :e file – Edit file in a new buffer • :w – Save any modifications to the current buffer. • :q – Quit Vim. If you have modifications you do not want to save, use :q! • u, <c-r> – Undo, redo 7 Command Mode: Navigation • Reopen simple.c – Use j, k, l, and h to navigate around the file as shown. This may take awhile get used to, but is very nice once you have it down. -
Comparative Studies of 10 Programming Languages Within 10 Diverse Criteria

In this paper, we will discuss ten programming languages: C++, C#, Java, Groovy, JavaScript, PHP, Schalar, Scheme, Haskell and AspectJ. We summarize and compare these ten languages on ten different criterion. For example, Default more secure programming practices, Web applications development, OO-based abstraction and etc. At the end, we will give our conclusion that which languages are suitable and which are not for using in some cases. We will also provide evidence and our analysis on why some language are better than other or have advantages over the other on some criterion. 1 Introduction Since there are hundreds of programming languages existing nowadays, it is impossible and inefficient -
