I have always been skeptical of rewriting working code - porting code is no exception to this. However, with the advent of TDD and automated testing it is much more reasonable to rewrite and refactor code.
Does anyone know if there is a TDD tool that can be used for porting old code? Ideally you…

This is very basic question from programming point of view but as I am in learning phase, I thought I would better ask this question rather than having a misunderstanding or narrow knowledge about the topic.

Is there an accepted general term that subsumes the concepts of variables, class instances and arrays? Basically "any typed thing that needs memory". In C++, such a thing is called an object, but I'm looking for a more language-agnostic term.

This has been in an effort to make things smaller…

After reading my initial two blog posts on New Cardinality Estimation, I received quite a few questions. Once I receive this question, I felt I should have clarified it earlier few things when I started to write about cardinality. Before continuing this blog, if you have not read it before I suggest…

LTO tapes, Maxell in this case, are often marketed as having 30 years or more shelf life when stored under "optimal conditions"
Is there a way to get a good estimation to the shelf life, given parameters such as relative humidity and temperature etc?
Obsolescence of the tapes aside, is there a way…

Hello.
I want to estimate the noise in an image.
Let's assume the model of an Image + White Noise.
Now I want to estimate the Noise Variance.
My method is to calculate the Local Variance (3*3 up to 21*21 Blocks) of the image and then find areas where the Local Variance is fairly constant (By calculating…

I've been asked to size a web architecture for an excessive number of concurrent users ( hundreds of thousands ).
I'm having a hard time convincing these people that unless you are in the top 5 of your country websites it's quite hard to hit those numbers.
Can anyone provide some real world case…

Suppose you are a project manager. You can estimate an effort in days for specific task for specific developer. After performing estimation you obtain some min and max values.
After this you delegate a task to developer. Actually you also set up deadline.
Which estimation is better to use when set…
