### Probabilistic bug hunting

December 8, 2013 |

Have you ever run into a bug that, no matter how careful you are trying to reproduce it, it only happens sometimes? And then, you think you've got it, and finally solved it - and tested a couple of times without any manifestation. How do you know that... [Read more...]

### Hard drive occupation prediction with R – part 3 – Predicting future ranges

June 22, 2011 |

On the second article, we saw how to use a Monte Carlo simulation generate sample of disk space delta for future dates and calculate the distribution probability of zeroing free space in the future. In this article, we will see how we can plot the e... [Read more...]

### Hard drive occupation prediction with R – part 2

January 21, 2011 |

On the first article, we saw a quick-and-dirty method to predict disk space exhaustion when the usage pattern is rigorously linear. We did that by importing our data into R and making a linear regression. In this article we will see the problems wit...

### Hard drive occupation prediction with R – part 2 – Getting the probability distribution

January 21, 2011 |

On the first article, we saw a quick-and-dirty method to predict disk space exhaustion when the usage pattern is rigorously linear. We did that by importing our data into R and making a linear regression. In this article we will see the problems with that method, and deploy a more ... [Read more...]

### Hard drive occupation prediction with R

August 14, 2010 |

On some environments, disk space usage can be pretty predictable. In this post, we will see how to do a linear regression to estimate when free space will reach zero, and how to assess the quality of such regression, all using R - the statistical soft...
