Learning from mistakes is not an easy task to accomplish

Learning from mistakes is not an easy task to accomplish It is common to read that we should learn from our mistakes. It is absolutely true. The problem when we talk about mistakes is to learn how to recognize a mistake, and which lesson we can take from it. Although it seems a simple task to accomplish, it is one of the hardest to do. Recognize a mistake The mistake analysis is a serious thing. First of all we should be able to recognize a mistake Then we should analyze what kind of mistake we are dealing with After we…

Ciao Marco!

Qualche volta bisogna ammetterlo, certi personaggi non sono come gli altri, hanno la capacità di segnare la cultura di un paese in maniera indelebile. Marco pannella è deceduto oggi. Un combattente, uno che ci credeva fino in fondo. Magari potevi non essere d’accordo con le sue battaglie, ma credo che in pochi abbiano il coraggio dimostrato da questo leone della politica. Uno che si è speso senza tregua fino alla fine per le sue idee; idee di libertà, giustizia ed uguaglianza, non dimentichiamolo. Verrà forse ricordato per la sua battaglia vittoriosa per il divorzio, o per le mille battaglie successive, ha…

unhappy employee are a cyber security concern

Have you ever considered the fact that the “best place to work” is something a security chap should take into serious consideration? A lot of people keep thinking that security is all about one of that technology, most of those expert master perfectly one of another specific technology and think they have the sacred graal of security. Since I am not so a big tech expert I am allowed to think that security isn’t in that specific technology, but in a systemic approach where technology cover just one part, and is just a part of a whole process. One of the aspect…

Cryptography, keeping on the big lie

So Cryptography would be a National Security Issue? I’m tired to be polite and politically correct when talking about encryption. Let us be clear and honest, all those crypto_war is a pile of crap. Every time I heard someone claiming that we should not enforce strong cryptography I wonder: to they have the slightest idea what they are talking about? Probably not, considering also most of the objections against cryptography I heard. Listening to those “enlighten” minds it seems that without cryptography the world be a sort of heaven where intelligence could have the possibility to solve any criminal case. And…

The IoT Files: The need for cryptography

The IoT Files: The need for cryptography One of the main arguments that should be touched by IoT discussion is cryptography. There is an undisputed consensus that cryptography is a mandatory requirement to preserve security and privacy in the IoT world, but we are far away for a general consensus on how to operate. The need for cryptography in IoT comes from two main aspects: Data security Data privacy The first need is clear; encryption is a mandatory requirement when we want to implement any form of authentication and non repudiation. Encryption is widely used even if we don’t know…

Historical memory, what is this about?

I wrote on memories yesterday. Personal memories and historical memories are the blocks of our life. We live for our memories since, at the end, are memories that create our thinking, our background, our experience, our knowledge. Personal memories are something ease to understand, is what we directly lived through direct experience. but those memories are just a portion of the memories we have and have to deal with. Another great portion of our memories is build into the society we are living, shaped trough communication (media, arts, word of mouth, storytelling), school and other tools. Some of those memories are…

Managers and Leaders are not the same thing

Managers and Leaders are not the same thing There is always a lot of talk about managers and leadership, but I sometimes have the feeling there is a little confusion on the subject. I can agree that a manager needs to have leadership qualities, as some other key soft skills, but leadership, per se, is not enough. Wait, this means that a great leader can’t be also a great manager? Exactly, a manager need leadership skills to be good, but this is only one of the several skills he need. He should be able to understand the job heshe is…

weak manager style

In a previous post ()  I tried to put some rationale on my thoughts about management, designing some of the characteristics a manager usually have (bad ones of course). One of the biggest “Ahas!” new and experienced managers (and the people who work for them) have experienced  is the realization that being a strong manager doesn’t mean being forceful or domineering. It’s just the opposite — strong managers are strong enough to lead through trust, whereas weak managers have to use the force of their job titles to make people listen to them. Most of the management style depicted (not…

Our memories are all we have

I am in China for work, with a few connection to the real world outside, so Italian news usually comes to me late, when I am able to connect to internet from hotel; great firewall allowing. Being isolated from the Italian reality put things into a different perspective, allow you to keep less news with more time to digest and think about. It happened a few days ago I learned of the death of Umberto Eco, one of the greatest Italian tinker of our age. He was a great writer, a great thinker, a truly free spirit. The first thing I did…

What is Openstack

OpenStack is an open source platform for creating and managing large groups of virtual private servers in a cloud computing environment. The platform supports interoperability between cloud services and allow businesses to build and deploy private cloud services in their own data centers. The National Aeronautics and Space Administration (NASA) worked with Rackspace, a managed hosting and cloud computing service provider, to develop OpenStack. RackSpace donated the code that powers its storage and content delivery service and production servers. NASA contributed the technology that powers their high performance computing, networking and data storage cloud service. OpenStack has a modular architecture…
