Questions Today marks five years since the start of Conversations with Kip Vlog. In celebration, I’m releasing two videos, one is a bit in the tradition of the bloopers of the past, showing that at times I don’t have the answers. The second is more serious, discussing the importance of reflection. First, consider that at times we don’t know everything we would like to about … Continue reading Reflection, Unanswered Questions and Goals for Financial System Transformation
Understanding tabulating system principles can be very powerful in analyzing legacy systems, even though card readers have not been used extensively for perhaps 40 years or more. In this post I’ll describe an approach I would take to replace a large bank’s customer deposit system. You can watch the video here. Daily Financial Cycle First, let’s be clear about what the daily financial cycle looks … Continue reading An Approach to Legacy System Analysis
This week’s episode focuses on the trade off between efficient programs and lazy programmers. A choice can be made when generalizing some problems to ask the computer to make a set of choices that the programmer wasn’t willing to make when he defined the process. This uses compute resources to make up for the programmer’s indecision or inabilities. If you’re interested in more about the … Continue reading Computer Efficiency and Lazy Programmers
In the final episode about how many of our financial systems are based upon tabulating system principles, we’ll discuss how to detect more specific information about those specific programs. Finding the posting programs within tabulating systems is an important pillar of understanding; many other processes hang off the posting program. Edit process precede posting, reporting typically follows. In looking for the posting programs, there is … Continue reading Tabulating System Metadata
Yesterday I came upon an article about some guys saving an IBM 360 Model 20 mainframe from the 1960’s. It seems appropriate to think about the system architecture which would have worked on that machine at the time, and it’s origins. The system would be been based upon tabulating systems. If today’s financial systems, and the tabulating System principles upon which they are based, were … Continue reading Data Discovery in Tabulating Systems
When investigating systems, often legacy financial and business systems, my simple descriptions in the prior videos begin to break down as we dive deeper: these systems are not always simple. Here’s what to look for next. Most of the program logic sits under the Perform Until End of File section. As systems developed, programmers recognized common program patterns for this phase, with small variations in … Continue reading Complexity in Tabulating Systems
Today’s episode of Conversations with Kip introduces a set of videos around the term Spaghetti Code. Many systems are not understood by today’s developers because they do not understand the principles of the underlying systems. Spaghetti code is intended to describe systems built with little structure. They don’t use structured programming approaches, use a lot of “go-to” constructs, have poorly designed sub-routines and a great … Continue reading Spaghetti Code or Tabulating System?
This week’s episode of Conversations with Kip is a conversation with Jim Hladyshewsky about his first assignment with the SAFR team, called “Show me the Money”, what now might be called a data science method for financial data. Show me the Money is a way of rapidly determining business rules and logic for posting processes without reading code. It recognizes that patterns of financial systems … Continue reading “Show Me the Money” with Jim Hladyshewsky
