Qest is a conference that I like for many reasons, and here is the call for papers for the 2010 edition of the conference. The conference website is here. Scope and Topics The International Conference on Quantitative Evaluation of SysTems (QEST) is the leading forum on evaluation and verification of computer systems and networks, through stochastic models and measurements. QEST has a broad range of interest — the common thread is that the evaluation be quantitative. The range of performance metrics of interest spans classical measures involving performance and reliability, as well as quantification of properties that are classically qualitative, […]

I am currently in the US for a few days, and today it’s turkey day. To stay on the thanksgiving topic, here is a nice infographic find on mint.com: A wide version is here. And now, it’s time to cook the turkey, and the mash potatoes…

First International Workshop on Quantitative Stochastic Models in the Verification and Design of Software Systems (QUOVADIS) Workshop at the ICSE 2010 3rd May 2010, Cape Town, South Africa http://deepse.dei.polimi.it/quovadis/ Motivation and Objectives: ========================== Modern software systems are increasingly complex and pervasive. They are often offered to clients as services, which must meet high level expectations in terms of predictability. They are embedded in a fluid environment that is constantly evolving, because of changes in the requirements, in the operating environment, and in usage profiles. Traditional software development processes and methods are unable to cope with the challenges posed by this […]

To find the beginning of the triangular adventure, you should read this post. To prove the lemma we use the following theorem that I am not proving in this post (if you want the proof, just let me know). Theorem Consider $latex N$ urns each filled with $latex m$ balls, and the following process: pick a ball in an urn chosen uniformly at random until the chosen urn is empty. The probability that one had to pick more than $latex O(N^{\frac{m-1}{m}})$ balls tends to a nonzero constant as $latex N$ goes to infinity. Proof (of the lemma) To each triangle […]

SPAA defines the term « parallel » broadly, encompassing any computational system that can perform multiple operations or tasks simultaneously. Topics of interest include, but are not limited to: – Parallel and Distributed Algorithms and Applications – Parallel and Distributed Data Structures – Parallel Complexity Theory – Parallel and Distributed Architectures – Multi-Core Architectures – Instruction Level Parallelism and VLSI – Compilers and Tools for Concurrent Programming […]

I found on this blog this infographic that shows the internet speeds and costs around the world.

The trend today is towards Business Intelligence and Customer Relationship Management (CRM) and I think we have all realised that for any capable web marketer, the three vital statistics are:  the KPI (Key performance Indicator), ROI (Return on Investment) and Web Analytics. So, let’s dive into the (customer) Marketing adventure, a field  which can be applied to most sales contexts including  the online, which don’t differ much from a more traditional ‘Brick and Mortar’ situation. Customer Life Cycle Who is a company’s good customer?  He/she is firstly loyal, and always returns to the company for a purchase to the point […]

Winston Chang (from stdout.org) is offering a Latex cheat sheet to the community. It’s here. As he says: « This is a latex reference sheet for writing scientific papers. Unlike many reference sheets available on the internet, it does not focus on mathematics, although some math symbols are listed. » Click on the image to go to the download page.
