Nothing beats C++ in multiple inheritance (which Java does not have and Groovy/Scala only mimic half arsed)

I have yet to encounter a non-contrived example where multiple interitance is a plausible solution to a problem. The simplified single inheritance and interface model caters for all practical examples, and *vastly* simplifies the internal workings.

Comment Re:Breaking the single, most common 1024-bit prime (Score 1) 71

The calculation to generate new primes is expensive (and in the past, was prohibitively so). As the prime numbers in DH are public (they are in the clear as part of the handshake), it was decided that using the same set of everything was a GoodIdea(tm).

This is not the case in reality, as a one-off week of cloud resource provides an attacker with sufficient data to decrypt the stream in realtime.

Comment Re:Why are you such an asshole? (Score 1) 290

The reason I ask is that the Linux model for 32 bit is to have a 4G/4G address space, where the user and kernel address space are completely disjoint

A 4/4 split is completely impossible. x86 doesn't switch CR3 or TR automatically. At an absolute minimum, the kernel needs all its entry points (exception, interrupt and syscall/sysenter targets), and hardware structures (active pagetables, GDT, LDT and TSS) mapped into all virtual address spaces.

Comment Re:When will Linux install and auto-compile based (Score 1) 58

When will Linux auto-detect the 'static' components of the hardware and do an install with a kernel compiled and optimized for that hardware - along with a vanilla kernel for emergency backup? (Something like Gentoo does)

Never - it is not in a general distros best interest. It is hard enough keeping on top of the kernel bugs with a signle configuration in use, let alone customising it to everyones hardware. Anyway, when it comes to drivers, the optimisations you can do are "dont load drivers you dont need", which is what already happens

The problem is, the fix I had to employ was to physically replace the co-opted DNS servers with more advanced equipment because the system software that was on them had no throttling capabilities nor was is capable of recognizing and rejecting suspicious queries.

Protecting against DDoS reflection attacks is very easy, but it requires all 1st-tier ISPs to perform egress IP validation, so packets coming from the end users trying to get onto the internet are checked that the IP address is correct. Filtering anywhere else is impossible because of transit routes, so by the time the second AS gets to inspect the packet, it could legitimatly be from anywhere.

The problem is that this costs money to implement and isn't in the interest of 1st-tier ISPs, so is unlikely to ever get done.


Matching Up Hotkeys for OS X and Linux GUIs? 83

I use a MacBook Pro for my main machine, but also have a Ubuntu desktop. I get irritated about switching between command-oriented hotkeys and ctrl-oriented hotkeys (cmd-a on OSX = ctrl-a on Linux/windows). I've looked over a lot of forums and have found that Gnome doesn't seem capable of changing hotkeys, while xfce and fluxbox can. The ideal solution would be a way to change system keys in X, or at the system level — that way I can keep compiz. Does anyone have any ideas or know a trick to change system hot keys?
