" Microsoft has drastically overhauled the network running its Skype voice-over-IP service, replacing peer-to-peer client machines with thousands of Linux boxes that have been hardened against the most common types of hack attacks, a security researcher said.
The change, which Immunity Security's Kostya Kortchinsky said occurred about two months ago, represents a major departure from the design that has powered Skype for the past decade. Since its introduction in 2003, the network has consisted of "supernodes" made up of regular users who had sufficient bandwidth, processing power, and other system requirements to qualify. These supernodes then transferred data with other supernodes in a peer-to-peer fashion. At any given time, there were typically a little more than 48,000 clients that operated this way. "

Microsoftin itsensä pitäisi jo hylätä omat viritelmät ja siirtyä Googlen tavoin Linuxiin. Windows on pilipalikäyttöjärjestelmä.
Koska skype vaatii kunnollista tietoturvaa, ei skype voi käyttää tavallista reikäistä linuxia, vaan grsecurity erikoisversiota, jossa pahimmat linuxin reiät paikattu.
Ääliö ei osaa edelleenkään englantia.

Microsoft joutui turvautumaan Linuxiin sen paremman turvan hakkerointia vastaan.
the boxes are running a version of Linux using grsecurity, a collection of patches

purkit ajavat grsecurity-linux, jossa pahimmat linux reiät on paikattu
Kaikki parhaat ohjelmat on Linuxille. Windows on yhteensopimaton grsecurityn kanssa.
Ahaa. Nytpä tiedämmekin, miksi näin pääsi käymään:

Syypää on vuotava linkura, jonka tietoturva on alkeellisella tasolla.
