Summary

I have good Python skills:

  • Using Python 2.7 I developed code to produce Python controlled audio output “on the fly” from music made with MIT’s Music21. Dr. Michael Scott Cuthbert, creator of Music21, said my solution was “elegant” and made other encouraging comments. See http://wp.me/p1zI3Z-5y
  • Using Python 3.1, I wrote a NoteWorthy Composer .nwctxt to XML file converter . See: http://tinyurl.com/yce9guh
  • I created a Python implementation of Posterous Inc.’s (Ruby-based) RESTful API2 (http://posterous.com/api/docs/pages/overview). Each of the 60+ API2 Actions have been implemented in a Python class method. All of the Python methods are very well documented, based on the API2 documentation. Here is a link to the current status of my work: http://tinyurl.com/8cx64gr

web2py

I have developed web2py apps using:

  • Application Layout using: [plugin_layouts, [Amaya, oswd.org], css]
  • Custom Forms using: form.custom.widget in the view.
  • Deployment using: WebFaction

I have had some part time Software Development contracts in this time frame. My condition has been improving since 2007 when my Stanford neurologist diagnosed me with a copper deficiency. I have been disabled since leaving HP and am presently recuperating.

(10/2001 – 10/2002) Theocom (Ficticious Busines Name for Joe Dorocak)

Java interface with the native operating system: Runtime and Process classes and System.getProperty() method. Drag and drop JTree GUI on the client: DragSource, DropTarget, DropTargetListener, DefaultTreeCellRenderer and TreeModelListener classes. XML persisted Java Bean based data architecture: XMLEncoder, XMLDecoder classes.

Also developed automated testing software for the prototype using Java and Perl. And, in support of the Theocom office IT infrastructure, I used VB to manipulate the Outlook Session Object and the Exchange Collaboration Data Objects (CDO) MAPI.Session Object to filter Outlook email messages programmatically, based on the content of the Internet Header. Also used WMI scripts to access Windows 2000 processes, services and scheduled tasks.

(3/00 – 9/01) HP Cupertino Enterprise Java Lab

Wrote Java code in support of the development of HPjconfig, a Java based tool used to tune the HP JRE & HPUX operating system to improve the performance of Java on HP systems.

Using a text editor and command line JDK, replaced code of a programmer who had left with GUI Swing components including JTable. Wrote table model object serialization methods. Sorted table model contents creating an indexed sort class and an associated inner class. Wrote copy and paste functions to help export table data. Packaged the HPjconfig application in JAR format.

Using the Sun jaxp.jar, parsers.jar and specifically using the javax.xml.parsers, org.xml.sax, and org.w3c.dom packages, developed classes to import and manipulate XML based performance parameters for HPjconfig.

Developed GenGoldData and GoldDataSort applications to convert performance tuning data from internal HP format to XML. Specifically using the Element, NodeList, Text, Node and DocumentFragment classes in the org.w3c.dom package.

Developed an expression evaluation application which took arithmetic expressions like “(a+c)*77” tokenized, converted to reverse polish notation, and interpreted results.

Developed an HTML based help system for HPjconfig with page searching and link browsing capabilities, specifically using Swing’s JEditorPane, its .getDocument() method and its addHyperlinkListener event.

Developed encryption classes to support the encryption of the HPjconfig XML database. Specifically using KeyGenerator and ObjectOutputStream to generate and serialize a “DES” key; the Cipher class to encrypt and decrypt the data, and BASE64Encoder/BASE64Decoder show the encoded data.

Successfully deployed an Apache web server with Tomcat’s JSP support, developing JSP server side web pages for technology assessment.

Developed regression testing driver software using extreme coding techniques in Java. Developed an interface for HPJconfig to the HP “Harness-9” automated nightly build testing facility using Perl.

Developed a Partner License Database updating and reporting system. Specifically designed the table schema and updating methodology for the database. For compatibility with Netscape 4 and IE4, wrote a Java 1.1.8 reporting Applet showing the database content with constantly maintained column headers using GridBagLayout, and opening a URL connection to the server data.

(8/99 – 10/99) HP Mountainview

Using HPUX, C, Sybase 11.0, and Microsoft SQL Server 6.5, wrote C code, embedded SQL, PL-SQL stored procedures, SQL querries and updates in support of HP’s Unix Hardware Order Fulfillment System.

(2/99 – 5/99) PersonalDisc

Client side and server side Java development. Using Microsoft Visual Studio 6.0, designed, implemented, tested and SUCCESSFULLY DEPLOYED a Client/Server Web Application based on IE4 on the client side, and Internet Information Server and an ODBC/SQL database on the server side. This effort entailed total responsibility for the GUI (Graphical User Interface) and database aspects of a multimedia kiosk. Performed Object Oriented Analysis and Design to define inter-object messaging sequences. Developed Java based executables and ActiveX Controls. Designed schemas, tables, SQL querries and update transactions for ODBC databases. Developed HTML and ASP pages with both client and server side scripting in Javascript, VBScript and mixed Javascript and VBscript using the Document Object Model (DOM). Developed remote scripting modules to communicate with server side ASP pages while keeping the client page constant i.e. without explicit navigation. Communicated with hardware control modules using DCOM.

(9/98 – 10/98) BreEZeWare, Inc.

Performed Object Oriented Design (OOD) Analysis on a custom 3-Tier distributed processing system which will be applied to a web based service. The service will be a significant adjunct to the scarce IT resources of small to medium corporations. The OOD Analysis generated inter-object messaging alternatives and attendant bandwidth, performance and development time attributes.

Developed software consisting of Java classes, fields and methods to mimic the desktop attributes of a target system on a client browser. The software used the Enumeration Interface to traverse an XML Document associating icon names with a .gif based icon representation. The software then used Microsoft AFC components to display each icon with name and a selection check box. The software associated a custom “ratio” layout manager with the mimiced desktop container so as to account for possible discrepencies between the target and client display resolutions.

(7/98 – 9/98) Theocom.

Using the GNU C++ compiler on the BSDI UNIX version 2.1, developed a CGI form mail program that successfully decodes the URL encoded text and and emails the content of the associated HTML form to the desired “secret” recipient. The key feature of the program is that the email address of the recipient remains secure, that is, it does not appear anywhere in the HTML page.

(3/98 – 5/98) Calico.

Using Visual C++, developed code in support of the integration of a Visio front end with Calico’s Concinity application. Developed a UML Object Oriented Analysis of existing code using the Rational Rose tool. Added methods and properties which sensing a Visio Drag and Drop event performed necessary state changes to local objects. Developed a special kind of .dll called a .vsl which is used to implement Visio addon features. Using VB 5.0, manipulated Calico’s Concinity application via OLE Automation to input parameters and receive results via inter-process communication.

(10/97 – 2/98) Neuronetics.

Did top down design and architecture of a project to embed the Neuronetics MindWizard product to implement an automated help desk application for the telephone industry. Performed preliminary database tradeoffs between MS SQL Server and MS Access. The software design controlled the questions to be asked of the user and the querries to be sent to the database, as well as the resulting diagnosis. In Microsoft Visual C++ 5.0, using MFC and OLE Automation, controlled the function of the MindWizard shrinkwrap software product. Using Class Wizard, added the Visual Logic Interface Class from the Type Library. Using CreateDispatch created the new instance of MindWizard and processed the SCODE return values. Set cause properties, initiated the Run method and Got effect properties of the MindWizard object. Displayed results in an MFC View based on CEditView. In Microsoft Visual C++ 5.0, using ADO, ActiveX Data Objects and MFC OLE techniques, developed prototype software for adding a database capability to the Neuronetics MindWizard shrinkwrap software product: Created and opened the Connection, Recordset objects. Created and loaded Field objects resulting from Queries.

Using VB 5.0, developed data structures, algorithms and Classes and Program modules that successfully demonstrated the interface of the MindWizard software product with Visio. Allowing MindWizard to activate Visio flowcharts with live data calculations. Using Visio’s VBA, developed Classes and Collections that stored the link and node relationships for a Visio flowchart. Developed procedures to generate Indices that sorted the Collections using indirect methods for speed. Developed a procedure to uniquely identify and separate node objects from link objects in a second pass. Parsed the process nodes according to a Top Down, Left to Right algorithm. (Also developed an algorithm to parse the process nodes by data dependency – this algorithm was characterized as “elegant” by my direct supervisor, Dr. Ram Gurumoorthy, in a report he prepared for upper management.) Executed the process nodes using Ole Automation to activate MindWizard and pass the results back to Visio for display in the data node at the appropriate connection point.

Using VB 5.0, supported development of an Ole Automation Client application which commanded the MindWizard neural net server to emulate the Kieras/Bovair cognitive simulation control panel for use by the NASA Human Machine Interface Design Group. Using VB5, created a custom toggle switch button from scratch using image bitmaps. Performed other GUI development tasks related to this project.

(11/96 – 9/97) THEOCOM.

Developed Java, JavaScript and CGI activated Web pages. Software was generated using Symantec’s Cafe and Microsoft’s J++. I have been approved by Sun Microsystems to display JavaSoft’s Jump to Java Logo. To quote Sun, “this (logo) program designates your site as a link to the most innovative developments in JavaTM technology.” Developed TCP/IP socket client server application. Wrote Java code to allow URL connection to CGI Post server using the URLConnection, PrintStream, DataInputStream and URLEncoder classes and associated methods including openConnection(), getInputStream(), println(), readLine(). Wrote HTML Fill-Out Form using the Post Submit method and CGI server Post form parsing programs in both Perl and C which appended entries to a text file database. Wrote Java Application that displays the recursive sizes of all subdirectories in a directory using FileDialog, GridBagLayout and GridBagConstriants classes. Developed a formatted number string class which formats ints and longs in a specified width, with or without thousand commas. Wrote MUSIC AUTHORING and other Java Apps and Applets using AWT Flow, Border and Grid Layout managers, Panels, TextAreas, Choices, AudioClip.loop() and thread methods etc.. Also wrote Java Application to generate .au files using FileInputStream, DataInputStream, FileOutputStream, and DataOutputStream classes. Wrote Java animation classes from scratch employing getImage(), imageUpdate(), and drawImage() methods. Wrote JavaScript code to pre-calculate Total Price and validate Quantity entry to be numerical.

(4/96 – 8/96) InterWAVE Communications.

Using Microsoft Visual C/C++, Finished porting a UNIX TCP/IP Client/Server – Server/Client application to Windows 95, NT, 3.1 & 3.11. Synchronized socket I/O for command/response proprietary protocol. Altered the WinMain and WndProc to initialize the app with a WM_COMMAND instead of in WM_CREATE. Posted a Windows message just before the message dispatch loop to IDM_INIT_APP. Added extern far function to flush the console output to the main window during file processing as a progress indicator. Added scrolling to the main window using SetScrollPos(), SetScrollRange(), ScrollWindow() API calls. Added several other features to the application including an MFC based filter window which was displayed in a separately spawned process due to the non-blocked TCP/IP socket I/O.

(9/95 – 11/95) I3 Design.

Developed VB Code for shrink-wrap sales force support product for a major software vendor on Win95 and NT. Altered SQL database querries for better performance and reliability. Dynamically updated progress bar under the timing control of the Windows API function – GetTickCount(). Activated DoEvents to allow Windows OS functions to proceed. Updated embedded Access Databases to conform to customer requests. Upgraded VB Code to support User required Menu Changes. Reconciled Standard and Custom Control Properties (Font, Bevel, BevelStyle) to be consistent. Using VB Debug Screen, isolated functional anomalies to form/module, object.method or object.property for Crescent Software’s “PowerPak Pro” Custom Control objects. For example csText masked data input control .ValidateMask, .Mask and .CharacterTable properties were updated for more user friendly functionality.

(3/95 – 6/95) Delta Airlines.

Developed Visual Basic applications that help Delta Airlines maintain their FAA documents. These applications, written in VB 3.0, perform client/server SQL database updates using DDE to a SUN/UNIX server hosting DOCUMENTUM, based on SQL for ORACLE 7.x, Microsoft OLE Automation controlling the Microsoft Word Basic object from VB and Far Point’s SPREAD.VBX.

One application in particular implements an “Integrated Solution” as described in the Microsoft Office Developer’s Kit (ODK). Using OLE Automation it commands Microsoft Word 6.0 to print a document that has been accessed via an SQL query to the DOCUMENTUM/ORACLE server the query uses the ANY keyword to perform an array oriented SELECT on the Database.

The application accomplishes this by presenting a pair of FAR POINT SPREAD VBX’s to the user on the main form load event. The user loads those documents to be printed into the right hand sheet from the left When the user presses the “Send to Word” command button, the App then performs a globally declared Windows API call to check if Word 6.0 had a running instance; if not, it creates a Word Basic object and sends object method calls to the Word Basic engine. Without any further user typing, the methods Open the existing Word document, and perform all the necessary WORD BASIC Commands to print the document list. The VB Word Basic object pointer is finally Set to “Nothing” to shut down the VB invoked instance of Word.
