Why NOT measure progress using subjective percents

The first busiest part of year is successfully survived and it’s time to go on with business tuesday blog posts again. As I’m working on some progress measuring features for some time I will document here my ideas about this topic on more general level so business people can also read about my experiences and ideas. This time we make deep-dive to percents that describe how much task in progress is completed.

Facade Pattern

Facade is known pattern for communication layer between system parts. Facades are classes that provide often simplified access to subsystems functionalities but they don’t set any limitations for using subsystem classes directly. Facades can be found from many API-s in different forms, This posting is quick introduction to Facade Pattern.

Test-running SharePoint timer job using console application

SharePoint timer jobs can be inconveniet to debug as you have to attach debugger to OWSTIMER.EXE after deployment. Often you must restart this process so it starts using latest version of your assemblies. When building something complex we want to run our code many times to see how it works and if there are errors. But deploying, attaching to debugger and so on – is there easier way to run timer job? Yes, there is!

Speaking at Global Windows Azure Bootcamp, Sofia

I’m happy to announce that I will be speaker at Global Windows Azure Bootcamp at Sofia, Bulgaria this year. I have two real-life based presentations there (you know well I don’t like those hello-world-presentations) and I have some valuable field information plus real-life code to share with you. Here’s few words about my presentations.

Composite Pattern: Handling child node collections

One problem related to composite pattern is how to implement operations over child collections. Composite classes have children and leaf classes not. There are many ways how to solve the problem of where and how to keep child nodes collection. In this posting I go through different options and analyze those solutions through different code examples.

IFileClient – Generalizing storage access in ASP.NET web applications

This is one of the examples from my presentation about how to port existing ASP.NET applications to Windows Azure and how to build hybrid applications that work in multiple environments. One of important aspects is file storage that may have multiple implementations for different technical environments. In this posting I will introduce you my idea about generalized file access in web applications.

Long weekend in Netherlands

Every human being needs some time off and now it’s my turn to have some free days before pre-Christmas rush. Last year I had my little pause in Netherlands and after getting back to work I was like code-monster: head full of new ideas and solutions, in extremely good mood and I solved many tough technical problems like they were first and easy levels of some game. Here’s my introduction to some miracles of Netherlands you may want to enjoy.

Generalizing storage access for Windows Phone and WinRT apps

When building application that works both on WinRT and Window Phone you use Portable Class Libraries (PCL) for shared classes. As there are many application specific things that are not same on different platforms or that are not supported by PCL then you have to make some architectural decisions when creating shared functionalities. In this posting I will focus on persisting data for offline use.

Composite Pattern

Composite pattern is used in many applications. It helps to build hierarchies of similar objects and handle slices of hierarchy as one. Maybe one of the most popular implementation of this pattern in .NET world is Nodes collection of ASP.NET TreeView control. In this posting I will introduce you composite pattern and provide some implementation tips and samples about it.
