No you don't need to - the encryption itself has so many variables you can just use the stuff they provide for you and adjust the needed variables for your needs. No modifying of code required. And you can be sure this time the encryption is implemented well :D Still, I doubt PS4 is not hackable but we will see. Will be interesting times!

In terms of performance very little. It will not harm performance.

In terms of developers little. The Home OS will essentially just be a jump point for launching their code. They will likely be able to disegard it mostly.

In terms of cost to Sony its a good choice. Clues in the name. Its free

BSD is one of the old Unices. In BSD was developed a solution for creating different net-services on the same machine, called ports. Now ports are part of the internet, it is very important.

Based on the BSD-code many derivates have developed, FreeBSD is one of them. FreeBSD is known as a stable server-system.

I think the advantages for Sony are the stability and the robust matured net-code over the other BSDs, and the license over Linux.

I think PS4 will be even more hard to hack than PS3... not impossible of course but Sony leaned a lot of hacking this gen lol

And to add a little more about the previous subject...

That is the best "explanation" I found in a Spanish forum from a Brazilian guy but he wrote everything in English because it didn't speak Spanish lol.

He was trying to read the PS3 HDD.

The curious part is that one "Each HDD is "individualized" the moment it is formatted on a particular PS3 unit. An individualized HDD CANNOT be used in another PS3 unit due to (in theory) a unit based signature being written to each HDD."

It is true... you need to use the backup utility to move your data to another PS3 or HDD... just a HDD to HDD full data copy on PC don't work.

PS. The "w/LBA48 enable BIOS" is to support files over 4GB on FAT32.

Too much risk and complexity in building groud up.

Nintendo has proven this already.

Ah yes, nice find, ethomaz. Well still we don't know if he is right ;)

But LBA48 is required for big hard-drives, not for files >4 GB :)

Either way, it is nice that we get some info on ps4 on the technical side!

Nice to know... I was thinking that reason was because the file size limitation lol.

The excryption makes everything unknow to make anybody have certain about what FS is.

The base of MacOSX is Darwin, an open-source UNIX developed by Apple and based long time ago on BSD-code. As all Unices it has many programs that work together. As far as I know XNU is the kernel. You can download the sources at Apple and compile it yourself to a working Unix without the graphical UI that Apple developed on top of it, not based on BSD and not open-sourced.

Nobody knows for sure

Both BSD and Linux are Unix-systems, truw, but they don't use the same codebase. While BSD was written as enhancements of the original Unix and later replaced all parts with own code, Linux was written new from scratch. BSD support binary Linux-apps, because the BSD-guys have buoilt a compatibility-layer. All Unix-systems are somewhat similar, so it is often easy to recompile Open-Source-programs for another Unix. That's why most Linux-apps run under BSD.
