Il calcolo dell’algoritmo dell’anno bisestile non è banalissimo, perché ogni hanno non si accumulano solo 6 ore ma anche alcuni “minuti” e quindi dopo un po’ questa differenza si fasentire, se non se ne tiene conto…

Secondo il calendario giuliano, sono bisestili gli anni la cui numerazione è multipla di 4: l’anno giuliano medio dura quindi 365 giorni e 6 ore (la media di tre anni di 365 giorni e uno di 366). Questa durata non corrisponde esattamente a quella dell’anno solare medio, che si ricava dalle osservazioni astronomiche: quest’ultimo infatti è più corto di 11 minuti e 14 secondi. Di conseguenza, il calendario giuliano accumula un giorno di ritardo ogni circa 128 anni rispetto al trascorrere delle stagioni.

Recently, we created an automated testing platform to achieve this objective. In this post, we would like to share our method and findings.

On these days I decided to tune a bit more, my new shiny linux server box. I started to set up fail2ban. I think fail2ban is very imporant nowadays because it is a good example of a tool for slowing down attacks without closing your server too much.
