Sorry, but it's "SHL" that has a duplicate encoding on x86. There are four slots for non-rotating shift instructions in "group 2": 4=SHL, 5=SHR, 6=???, 7=SAR. The /6 variant looks like it ought to be "SAL", and it is. However, unsigned left shifting is equivalent to signed left shifting, and thus the two opcodes end up doing the same thing. The original 8086 happy processed this instruction as a signed left shift because of how it interpreted the opcode bits, but that's the same as an unsigned left shift.

This was retained in modern processors, whereas "pop cs" was not.

It's interesting to note that the code uses two "undocumented" 6510 instructions:

lax $91
anc #$00 ; clears carry for sinadd below

These instructions are undefined; they work by taking advantage of the internal CPU architecture to execute a hybrid of other legal opcodes. A lot of other older processors have such behavior, such as the Z80. Even the 8086 had a bit of this: "pop cs" and the second encoding of "sar" come to mind. (The 8086's "pop cs" was stolen by the 286 to mean an escape to a second opcode page.)

But the Tea Party was most certainly in the history of the United States.

I think that the biggest scientific discoveries coming this century will be about what we can't do. We'll progress significantly in applied sciences such as medicine, but in physics, we'll likely prove the impossibility of many things of which we dream.

Many of us like science fiction stories, but the reality is that they are not dreams of the future - they are merely a modern type of fantasy. We keep dreaming of the stars even when it's impossible. Unless we find a mass relay embedded in Charon.

I liked Mass Effect 3, except the ending. They have issues, but like, the worst company? Monsanto and Blackwater/Xe/Academi are far, far worse.

Even in video games, EA isn't the worst: look how bad Sega's Colonial Marines was, or the crap Sony has pulled with the PS3.

Unlike Chrome and Internet Explorer on Vista/7/8, Firefox doesn't run a child process in a sandbox to better protect the browser against exploits. Firefox runs entirely as a normal user process, and thus can access anything that regular processes can. An exploit running as an ordinary user can steal your bank account passwords and act as a zombie almost as effectively as an exploit running with root access.

I stay with Firefox only because I dislike tabs. Unlike Chrome, Firefox still has an option to open links in new windows instead of tabs.

Sony claimed that removing Linux from the older systems was for security, but the PS3 ended up getting hacked to hell anyway. Sony really should have lost that lawsuit over removing a feature from the old models.

With consoles, the best versions are generally the first or second versions, because over time, the company releases systems with fewer and fewer features.

That is such BS. Atheism is only the least liked among those categories. Add some other minority categories such as transgender people, burglars, car salesmen, and pedophiles and you'd get lower ratings.

Religion is a virus. A virus is a chunk of rogue program code that tempts a host into executing it, at which point the host is programmed to make copies of the code. Biological viruses have cells as hosts, and DNA or RNA as their program code. Computer viruses have computers as their hosts, and machine code as program code. Similarly, religions have minds as their hosts, with mind programs--ideas--as their program code.

The ultimate irony is that the Abrahamic religions don't believe in evolution, when it is precisely natural selection that led to their existence and dominance.

The song from the Moon is in the top 10 best NES songs on many lists. They need to make sure that they don't break it.

Capcom ruled NES music. The "SupraDarky" best video game music list has it at #40 - out of all systems' songs.

I hope Capcom is having IntiCreates make it.

How do you do anything about this when your district's congressman is completely opposite your views on almost every issue? Especially when you didn't vote for him. Any letter writing would go to the technologically-clueless equivalent of /dev/null.

A patent troll losing their case in Marshall, Texas?

This ROM has the pie factory level, but it has the NES title screen. How's that work? TFA says the 2010 ROM, but what's that from?

If the daughter finds them OK, what's wrong with it? Maybe she likes "girly" things.
