rubberecycle.com review
There isn’t much I can say about this company. They seem very legitimate by all indications (domain name registered more than 10 years ago, with the physical address of the company, no complaints on the web, etc). Their goal seems also very laudable: creating playground surfacing out of recycled tire rubber. While I don’t have…

Medicalhealthinsurancetoday.com review
Today I’m reviewing a site which has the goal of comparing different private health insurance companies and giving you the cheapest one. Unfortunately I’m not familiar with the USA insurance rules (because I’m on a different continent :-)), so I can only comment on generic impressions related to this site: The domain was registered in…

Setting the maximum number of opened files under Ubuntu (for JProfiler)
As I found out “on my own skin”, setting fs.file-max in /etc/sysctl.conf is a BAD idea. It can render your system useless in one step. Please don’t do it! If you did it, use the recovery mode to roll back the change. Also, currently I would only recommend doubling the limit (ie going from 1024…

Microbenchmarking is the practice of measuring the performance characteristics (like CPU, memory or I/O) of a small piece of code to determine which would be better suited for a particular scenario. If I could offer but one advice on this, it would be this: don’t. It is too easy…

Doing some estimations
This is again one of those topics which I like to rant about, so I give you the short version: when you see a number, question it! Most of the numbers thrown at us in different media can be disproven quite easily and it is our responsibility as people not to just repeat whatever we’ve…

Audio quality
This is just one of those topics which comes up from time to time in my life (probably because I consume a lot of media). I was recently watching the Jim Zemlin interviewed by Jeremy Allison (Jim Zemlin is the Executive Director of the Linux Foundation) on the Google Open Source YouTube channel and was…
