Is it important to use consistent java version alternatives?

I recently updated my JRE and a question came to mind.



I finally understood how alternatives work, so I successfully updated my alternatives for java and javac to the newest downloaded version. Last time I updated it I just copy pasted the update-alternatives --install and --config commands and did not understand the purpose of them.I feel very proud of being able to understand how symbolic links are used to keep the system robust and able to switch back and forth between alternatives. Yay Me!



However, I noticed that you can actually provide alternatives for several java bins, such as javah javap javadoc javaws jinfo ... etc.



I was wondering, is it important to add alternatives for all those bins? I think it might help out preventing some inconsistencies while using diferent JRE versions.



Is it relevant? at which point is my computer using those bins? is there any significant difference between the openJDK bins and the Oracle ones?

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this
