8230;requires more than just good programming. Lessons learned from 13 failed software products. 8220;No physician is really good before he has killed one or two patients.” – Proverb. Software entrepreneur culture is full of stories of the products that succeeded. But what about the products that failed? We rarely hear much about them. This can lead to a very skewed perspective on what works and what doesn’t ( survivor bias. Why it was judged a commercial failure. The person taking the time to record the...

Python – Number Cruncher
https://excelicious.wordpress.com/code-samples/python
While I primarily write code in VBA and SAS for my work, I have been fooling around with Python for quite a while. I have to say I vastly prefer the syntax to VB – in my opinion it’s a lot cleaner and simpler, meaning a lot more done with a lot less work. For that reason, I chose to attack the Project Euler. If you like, you can download all the functions in a single file here. Leave a Reply Cancel reply. Enter your comment here. Fill in your details below or click an icon to log in:. On Type or Class?

A couple of PowerShell scripts – Number Cruncher
https://excelicious.wordpress.com/2015/03/23/a-couple-of-powershell-scripts
A couple of PowerShell scripts. March 23, 2015. March 24, 2015. I’ve been making a little more use of PowerShell recently. It’s a very handy addition to the Windows environment, certainly it’s a lot easier to use than the traditional command line, and it’s a lot easier to find your way around. I figured I’d share a couple of the scripts I’ve used for some specific tasks to do with file management, in case someone found this handy. Etls w s = s) (etls recnt[,=]) )-1 # Extract lines from SAS ETL source cod...

A few functions that aren’t contained in the math module – I’ll continue to add to these as time permits. A recursive implementation of Euclid’s algorithm to find the greatest common divisor of two numbers:. Def gcd(a,b): pre: a, b ve integers calcalates gcd by Euclid c = max(a, b) d = min(a, b) if c%d = 0: return d else: return gcd(d, c%d). Using the gcd function to return the least common multiple:. Def lcm(a, b): pre: a, b ve integers returns least common multiple of a and b return a*b/gcd(a, b).

Analytic functions like LAG, LEAD, FIRST VALUE and LAST VALUE are a very useful addition to Oracle SQL, enabling retrieval of aggregate results without the need for self-joins. LAG, for instance, will allow you to get the value of a column from the previous row in a group of rows. The report returns for a given office any transfers in or out of a specified office over a period bounded by STDATE and ENDDATE. So what can we do about this? Well, some people w...

Random Sampling in VBA – Number Cruncher
https://excelicious.wordpress.com/2009/02/07/random-sampling-in-vba
Random Sampling in VBA. February 7, 2009. February 8, 2009. Occasionally we get asked to provide random samples from our database, and it’s the sort of thing that can be done very easily in SAS. For example, here’s a SAS routine I have often used to extract a sample. Of size 100 without replacement from a large dataset. I can’t remember where this code originally came from but I definitely can’t take credit for it):. Data sampleset (drop=remainder size);. Do while (size 0);. LOb = lOb 1. On Type or Class?
