Creeping Determinism

Let’s say that you won the lottery. That would be great, wouldn’t it?

Code Generators, You Suck. Well, some of you do.

July 5, 2011 - wssf

The scaffolding style code generators that generate out a good starting point from which standard coding takes over, those are very useful.

The Microsoft brand “design surface” based code generators (TableAdapters,WSSF) where the uml diagram of a class needs to be edited, rather than the actual class, those are more harm than good. if fact they slow development way down.

The design surface itself, is not necessarily a bad concept. it is just a GUI over top of a XML document. Just don’t use it to generate repetitive code. If code is repetitive, factor it out until its DRY. Don’t break out the code generators.

ReturnOnException Aspect (postsharp)

This comes in handy sometimes.

Attribute Based Caching Project Covered in infoQs

April 12, 2011 - attribute-based-caching c#

David Cookery did a short write up of my AOP caching framework on infoQ. As a result downloads and usage have spiked.

Question':' Caching and postsharp is not working in my project?

You have made a project using attribute based caching, but the cache isn’t being hit?

Incrementing

March 27, 2011 - tags data

Generic Hierarchical Meta data is cool! There are many ways to implement it with a standard relational database. Most of them are considered anti-patterns, but sometimes we need to optimize for flexibility, not raw database performance. Here are some of my notes on the subject:

Attribute Based Caching 1.2 Released

January 29, 2011 - attribute-based-caching c# release

Attribute Based Caching 1.2 has been Released. It’s still the .net only caching library that has declarative cache invalidation.

Attribute Based Caching 1.1 had almost 100 downloads! Release 1.2 contains some small improvements like disk based cache and a time-to-live setting.

Cache 1.2

Enterprise Software Authorization / Security

December 5, 2010 - row-level-authorization field-level-authorization

Security Thoughts:

There are generally three types of authorization in enterprise applications:

1. Role based security - Which actions can a user do - aka role-based access control
2. Entity level security - A user can only perform an Action on certain objects/data - aka row level security
3. Field level security - A user can see or edit only certain fields of an entity – (this is really fine grained and usually a bad idea)

Parser Combinators in C#

November 20, 2010 - parser parser-combinator antlr parsec f# c# nparsec

Haskell has parsec, f# has fparsec. I went searching for a good option for creating parsers in c#.

Project Euler #24 in c#

November 11, 2010 - euler c#

A permutation is an ordered arrangement of objects. For example, 3124 is one possible permutation of the digits 1, 2, 3 and 4. If all of the permutations are listed numerically or alphabetically, we call it lexicographic order. The lexicographic permutations of 0, 1 and 2 are:

012   021   102   120   201   210

What is the millionth lexicographic permutation of the digits 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9?
