Slashdot - Na Slashdotu se je pojavila zanimiva novica, ki govori o nedavni raziskavi podjetja mi2g. Raziskava, ki je trajala 12 mesecev, je ugotavljala, kateri OS je najbolj primeren za delovanje računalnika brez prestanka -- 24/7. Raziskava je bila naravnana tako, da je simulirala osebne računalnike, računalnike v podjetjih in računalnike, ki jih uporabljajo vlade držav.
Rezultat je zanimiv, saj naj bi bil najbolj zanesljiv operacijski sistem OS X. Kar je pa še bolj zanimivo pa je to, da naj bi bil Linux najbolj nezanesljiv OS, ko govorimo o ročnem vdiranju v sistem, saj naj bi bil neuspešen se ubraniti v 65.64% primerih. Vendar pa je v večini primerov vseeno Windows zavzel neslavno zadnje mesto. Prav tako se je za izredno zanesljivega izkazal tudi BSD, ki se je edini lahko kosal z OS X v večini kategorij.
Avtor članka pa opozarja na eno izmed glavnih pomankljivosti te raziskave -- v njo niso vključeni virusi, črvi in ostale nevšečnosti Windows sistemov.

Ko sem prebral osnovni članek, se mi je zaradi metodoloških pomanjkljivosti obraz obarval rdeče... 
Da si zaradi tega ne bi trgal dragocenega casa, sem spodaj paste-al dva komentarja iz slashdot-a, ki v glavnem povzemata moje mnenje.
The problem with this study isn't that it can been seen to say that Windows is more secure than Linux (which it doesn't say, specifically denies it's saying it, but with Linux users will think it's saying and flame away).
The problem is that they claim to be trying to find the "most secure" OS, and then look at the % of total attacks against each type of system instead of the average per installation of each type. If I set up 5 insecure "A" machines and 100 more secure "B" machines, and find that there were 5 attacks against the A machines and 20 against the B machines, I can conclude that the B machines are least secure because they account for 80% of attacks, or that A machines are least secure because they're attacked 100% of the time vs. 20% of the time. The raw numbers are completely meaningless in the context they're presented in, and the "news alert" itself show they're either intentionally misleading people or they're incompetent and need to hire a statistician with a big clue stick.
By the way, I do think the BSDs are probably "more secure", as they claim, but their methodology makes me ashamed to share their opinions.

Umm, no, it's because their methodology is a load of unscientific garbage, and it's obvious that the people who wrote the study don't have even the most basic understanding of statistics or scientific method. My disagreement with the methodology has nothing at all to do with their conclusions, and everything to do with how they reached them.
I'd feel the same about someone who said that evolution was a better theory than creationism, and went on to "prove" it with fake fossils they made in their basement. Being right for the wrong reasons is just as bad as being wrong.

se ne čudn da majo BSDji prbližn iste rezultate k OSX glede na to da je OSX narejen na osnovi BSDjov....

Poglejte prejšnji novici in videli boste, da ne znajo napisati nič novega in se samo ponavljajo.

CaqKa: tu sem te čakal. A sem jaz že kdaj objavil kakšno raziskavo?
