apache 6 The Apache Software Foundation is best known for their HTTP Web Server, Apache. Custom Visuals' Web Server and approximately 64% of the web servers making up the internet run on Apache. The Netcraft service will verify Custom Visuals is running [an error occurred while processing this directive]. System Load
awk 1 One of the older pattern-recognition tools. Largely replaced by advances in shell programming languages and Perl. N/A
bash 6 bash (Bourne Again SHell) is one of several Bourne Shell (sh) compatible shells. It shares many features with sh, ksh and zsh. webBack.sh
BBEdit 10+ BBEdit is a high-performance HTML and text editor. I use BBEdit for C++, Java, Perl, Shell and HTML programming. Nearly 100% of this site was developed using BBEdit. BBEdit
bourne 10+ Bourne is the original UNIX shell. Several additional shells were created to extend its functionality, such as ksh, zsh and bash. out2dat
C/C++ 3 C++ is one of the most common programming languages in use today. I've developed with both C and C++ off and on since 1991. I've used C++ for image processing applications and to augment other applications such as IDL and PV-WAVE. N/A
CGI 6 CGI is Common Gateway Interface. CGI programs are the basis of interactive forms on the web. These forms can do anything from allowing feedback to be emailed to the webmaster, to complete interactive applications. cfgNETFTP.pl
CVS 6 CVS is the Concurrent Versions System, the dominant open-source network-transparent version control system. I've used a variety of Source Code Management (SCM) systems along the way, but use CVS on my personal projects or for clients not requesting a particular SCM. I've also used ClearCase, SCCS, RCS and PVCS. header.pl
cron 10+ Cron is used to schedule commands to be run at specified dates and times. FTP backup
csh 10+ csh was the first Bourne Shell (sh) replacement. It uses a different syntax than the Bourne Shell, which makes it better suited to command line use than programming use. cshrc
DBA 5 Database Administrators are the folks that set up and maintain databases. Maintenance includes everything from granting user access to backup, purging and restore of data. I've been a DBA for MySQL, Ingres (now PostGreSQL) and helped out with some Oracle databases. dbDump.sh
DBI/DBD 6 Database Independent and Database Dependent interfaces for Perl. These interfaces work together to provide access to a variety of databases, including Oracle, Sybase, Informix, MySQL, etc. These interfaces merge the data processing strengths of Perl with the data storage strengths of databases. Perl's DBI/DBD is an excellent substitute for vendor-specific enhancements such as Oracle's PL/SQL, Informix's 4GL and Sybase/Microsoft's Transact-SQL. report_LogProc.pl
Dreamweaver 2 Dreamweaver is a GUI-based Web Site development tool. I used Dreamweaver to establish the initial layout of logos, buttons, borders, etc. for this site. Approximately 5% of this site was developed using Dreamweaver and the rest with BBEdit. Dreamweaver
ETL 4 ETL (Extract, Translate, Load) refers to three separate database functions which are often combined into a single tool. ETL can be used to process a subset of data for various purposes such as reports or the population of a data warehouse. The link shows an ETL application I developed while working at Pilot Networks to process data from multiple log files into different database tables. load_LogProc.pl
FTP 10+ FTP (File Transfer Protocol) is one of the older mechanisms to allow files to be sent between computer systems. I have developed several programs for managing FTP transfers. ftpDump
grep 8 grep is the Global Regular Expression Parser and is used to look for data within files. It is commonly used within shell programs to check for or extract data from a file. rgrep
HTML 9 HTML is the HyperText Markup Language - the main language of the web. This page, and the vast majority of all sites are written using HTML. N/A
http 5 HTTP is the HyperText Transport Protocol - the communications protocol used to connect to servers on the World Wide Web. Its primary function is to establish a connection with a Web server and transmit HTML pages to the client browser. N/A
Informix 1 Informix is one of the popular Relational Database Management Systems (RDBMS). It competes with other RDBMS's from vendors such as Oracle, IBM, Sybase, Ingres, PostgreSQL and several others. N/A
Ingres 1 Ingres is a Relational Database Management System (RDBMS), that has seen a deteriorating user base over the last decade. I was a Systems Administrator and Ingres DBA while working on a covert electronic surveillance project. This project was featured on The Learning Channel, when it was used to help track Pablo Escobar, the notorious Columbian drug dealer. N/A
Java 1 Java (not to be confused with JavaScript) is a portable, high-performance, object-oriented programming language. It is derived from C++ and does a better job of delivering on many of the promises of C++, especially in platform independence. Java is often used in web-based applications, but is very adept as a complete application programming language. The link shows a web site using a Java-based graphing package to show the system load of this server. System Load
JavaScript 2 JavaScript (not to be confused with Java) is a scripting language that can be embedded in HTML to provide dynamic web pages without using CGI programs on the web server. It is not a competitor to Java and/or CGI, but more of a complementary language to both, providing additional capabilities for web applications. N/A
korn, ksh 10+ David Korn's shell is one of several Bourne Shell (sh) compatible shells. It shares many features with sh, bash and zsh. EBMadd
LWP 5 Libwww-perl (LWP) is a collection of Perl modules which provides an application programming interface (API) to the World-Wide Web. I've used LWP to automate downloading of hundreds of files from an internal secure web site on a daily basis while working at Providian Financial. This allowed the Network Operators to make better use of their time, as well as to eliminate a major source of human error. Automation
MySQL 4 MySQL is the most popular open source RDBMS. It is especially popular with web site administrators. It has recently gained capabilities that put it at or near the capabilities of some of the best commercial products. DTDaily.pl
OOD, OOP 4 My first exposure to Object Oriented Design and Object Oriented Programming was while taking C++ classes in 1991 for California Microwave. I've also taken additional classes with OOD and OOP emphasis in 1993 in Ada while at Aerojet and once again with C++ in 1996 while at Hughes STX. I continue to use it with IDL, Java and Perl development. N/A
Oracle 2 Oracle has grown from its humble beginnings as one of a number of databases available in the 1970s to the overwhelming market leader of Relational Database Management Systems (RDBMS). It competes with other RDBMS's from vendors such as Informix, IBM, Sybase, Ingres, PostgreSQL and several others. I've used Oracle at several companies: Hughes STX, Globalstar, Zoom, Pilot Networks and Providian. N/A
Perl 8 Practical Extraction and Report Language - the duct tape of the internet. Perl is used for a variety of tasks such as system administration, database access, CGI programming, and a whole laundry list of other uses. Nearly every page of this site has some interaction with Perl in one form or another. Perl Code Examples
PL/SQL 2 Oracle's PL/SQL is the Procedural Language wrapper around Oracle's SQL. Other database vendors offer similar programming language extensions, such as Informix's 4GL and Sybase and Microsoft's Transact-SQL (aka T-SQL). These languages perform the majority of the duties of a language such as C++ or Perl, but are tied very closely to the database. The tradeoff between using something like PL/SQL and Perl is that the PL/SQL program will usually perform better, but with less flexibility to work with other system applications, and no flexibility if the underlying database were to be switched with another. I've written small applications with PL/SQL and much larger applications with embedded SQL in C++, Perl and Shell. I've also used Perl's DBI and DBD structure to work with multiple databases simultaneously. N/A
sed 4 sed is the UNIX Stream EDitor. It provides the capability to make modifications to files from the UNIX command line. mvFTPName
sh, shell 10+ sh, also known as Bourne shell, is the original UNIX shell. Several additional shells were created to extend its functionality, such as ksh, zsh and bash. sh has also been extended since its initial creation. dbDump.sh
SQL 7 Structured Query Language (SQL) is the standard language used to access databases such as Oracle, Informix, DB2, MySQL, etc. Most vendors have an extended version of the language to provide additional functionality and to provide a means of differentiating themselves from the competition. load_LogProc.pl
ssh 4 ssh is a program for logging into a remote machine and for executing commands on a remote machine. It is intended to replace telnet, rlogin and rsh, and provide secure encrypted communications between two hosts over a network. I use SSH when working on remote sites from home for software development. N/A
Sybase 2 Sybase is one of the popular Relational Database Management Systems (RDBMS). There are two main flavors of Sybase databases, ASE and IQ. ASE is geared towards transaction processing, offering a tradeoff in performance between inserting, updating, selecting and deleting data. IQ is aimed at the data warehousing market and offers phenomenal selection speed while sacrificing insert, update and delete speed. It competes with other high end RDBMS's from vendors such as Oracle, IBM (DB2), etc. I used Sybase when working at Kinko's and Citadel Investment Group. System Load
tcsh 3 tcsh is an improved version of csh, the first Bourne shell replacement. It uses a similar syntax as csh, and is thus more suited to command line usage than programming. N/A
Tivoli 3 Tivoli Workload Scheduler (TWS) is the application I've used in IBM's Tivoli family of products. It is used to automate scheduling and progress of multiple tasks across multiple UNIX and Windows systems. Tasks can be started on one system and rely on steps running on other systems for completion. The Tivoli scheduler allows the specification and coordination of this interaction. N/A
telnet 8 The telnet command is used to communicate with another host using the TELNET protocol. It is an insecure method and is usually replaced with ssh, which provides for secure communications between hosts. N/A
vi 10+ vi is the default text editor for UNIX systems. It is highly configurable and allows for a great deal of customization. The link shows the configuration file I use to provide templates and shortcuts when developing software. exrc
XML 2 XML has the flexibility to encode everything from web pages to legal contracts to books, and the precision to format data for services like SOAP and XML-RPC. It supports world-class standards like Unicode while being backwards-compatible with plain old ASCII. N/A
