However, do you truly believe that he's a neo nazi? Does anyone?

Some day, people will realise that most of the time, it makes no sense to call a person "racist" (or most other "-ist"s). Most of the time, "racist" is a property of an utterance or an act, not a person.

There are exceptions. This guy isn't one of those exceptions.

Comment Re:What is an OS? (Score 1) 128

Because we always have. The term "operating system" has always referred to the foundation software on any machine, from the kernel to the standard operating environment.

Are KDE and GNOME OSes now?

No, but they can form part of an OS.

Comment Re:Zero Page memory locations (Score 1) 606

Later I got me a 6502 and kept looking at it and thinking how lame it was. No matter how I looked, whatever angle I considered, I couldn't shake the idea about how limited the 6502 was. To be fair, of course the design parameters were different, not to mention the age of each one.

The net effect of the design tradeoffs mean that the Z80 and 6502 have almost the same power, achieved by different means. The code density, for example, turns out to be almost exactly the same. The 6502 has fewer instructions, but all opcodes are one byte. The Z80 has more registers but the 6502 has zero page addressing.

Interestingly, the 6502 is still being used today and the Z80 is not (except for retro gear, obviously). The main reason is that the 6502 has an extremely low interrupt latency. If an interrupt occurs, the 6502 can be running interrupt handler code in at most 5 clock cycles. So you can find 500MHz soft cores in various ASICs if you know where to look.

They do, however, spend millions on ads that they think will sell their products, and it happens that "Yeah, we think Trump sucks too. Drink Budweiser" sells products. You can probably figure out why for yourself.

Because Democratic voters prefer craft ales?

That is not what we call "production code", even if it is strictly speaking production code.

Haha, well, the person who wrote the query optimiser in your database server would probably differ with that opinion... That was my job a long time ago.

Perhaps you did not see my other posts.

Of course. This is Slashdot.

Of course you can. You just figure out maximum recursion depth, and then check if there's enough stack space.

Your mission, should you choose to accept it, is to figure out the maximum recursion depth for Tarjan's strongly connected components algorithm given an arbitrary directed graph. It must be more efficient than just running the algorithm.

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
