Guy Harris Re:Stop posting opinions in TFS! (54 comments)

Now the entire comment section for this article will essentially be a huge subthread for that guy's inflamatory comments.

Yeah yeah, I know this is par for the course for /. and that's the part that really sucks.

Are you sure that's not the intent for /.?

Schizophrenia Is Not a Single Disease

Guy Harris Re:Eugen Fischer (215 comments)

I'd expect most people to interpret "eugenics" as the Greek stems for "good" and "genes", because that's where the word comes from. A fairly obscure nazzy doktor with a similar name isn't what tainted the word.

I'd expect most people neither to associate it with the Greek stems in question nor with Eugen Fischer; I'd expect them to have no clue where the word came from.

Schizophrenia Is Not a Single Disease

Guy Harris Re:Then I guess you could say... (215 comments)

I'd be cool with it if it were Ed Harris

If you're referring to Pollock, hee came across in the movie as being manic-depressive, not schizophrenic.

Artificial Spleen Removes Ebola, HIV Viruses and Toxins From Blood Using Magnets

"When antibiotics are used to kill them, dying viruses release toxins"

Too bad SlashDot isn't a science web site...

Neither is the International Business Times, whence this article refers.

The web site for Nature magazine, however, is a science web site, and there's a much better story there on the same topic.

I call bullshit on this. Not a credible source, and whoever submitted the article bungled the science...

A better source is the article in Nature .

Artificial Spleen Removes Ebola, HIV Viruses and Toxins From Blood Using Magnets

Guy Harris Re:Say what now? (105 comments)

When antibiotics are used to kill them, dying viruses release toxins in the blood that begin to multiply quickly.

Is it just me, or is this sentence completely devoid of any scientificic sense in many different ways (antibiotics killling viruses? Toxins multiplying ??)

No, it's not just you, and, yes, that sentence is completely devoid if any scientific sense. Better sentences can be found in the news article from Nature .

Artificial Spleen Removes Ebola, HIV Viruses and Toxins From Blood Using Magnets

Guy Harris Re:Woohoo!! (105 comments)

Yeah, for years we were told magnet therapy was bullshit. Now there's money to be made by "legitimate" medicine, though, it's suddenly scientifically acceptable.

Well, there's "magnet therapy" as in "wear a magnet on your body", and there's "magnet therapy" as in "coat extremely small magnetic particles with a protein that binds to bacteria, viruses, and bacterial toxins, run your blood through a machine where the particles bind to the bacteria/viruses/toxins and get magnetically removed from the blood, and pump the blood back in".

It's quite possible for the first form of "magnet therapy" to be bullshit and the second form of "magnet therapy" to work.

Turning the Tables On "Phone Tech Support" Scammers

Guy Harris Re:I just unplug my landline phone (208 comments)

So, why do you waste money on the phone?

It provides a convenient phone number to provide to people who require one but to whom you don't want to talk, e.g. charitable organizations that will pester you to increase your donation. Turn the ringer off, give it an answering machine or similar service, and let people leave messages which you pick up later.

(It may also work better for speakerphone calls than a mobile phone.)

How Scientific Consensus Has Gotten a Bad Reputation

Guy Harris Re:Worse than that... (770 comments)

"Rejects empirical data" is another way of saying "taking it on faith", i.e. the Austrian school is a religion by another name.

Oh I feel your pain. I've had to put up with those damned mathematical religionists taking it on faith that not all primes are odd, when time after time my experiment taking a random sample of one thousand of the first billion primes has kept showing them all to be odd.

And I've had to put up with those damned geographers claiming they've seen triangles with three right angles when it's been mathematically proven that the sum of the angles in a triangle is 180 degrees! "Empirical evidence" indeed!

How Scientific Consensus Has Gotten a Bad Reputation

Guy Harris Re:Worse than that... (770 comments)

Another possibility is that the "well-reasoned logical argument" wasn't actually well-reasoned. For example, I've seen a perversion of the Austrian School axiom

And, of course, an axiom is just a starting point; if the axioms are inconsistent with each other, or with reality, the conclusions drawn from the axioms could be bogus, no matter how air-tight the reasoning.

Responding to Celeb Photo Leaks, Reddit Scotches "Fappening" Subreddit

Guy Harris Re:Bah humbug censorship (307 comments)

Consider also that the technicalities of a backup are beyond most non-technical consumers. Which is the group most people, including celebrities, fall in to.

They wouldn't be if the phone wasn't a deliberately arcane restricted POS.

Because some other type of phone would require you to understand the technicalities of a backup? Sounds like the kind of phone most non-technical consumers wouldn't use.

Or because, with some other type of phone, the technicalities of a backup would be simple enough for non-technical consumers to use?

Choose Your Side On the Linux Divide

Guy Harris Re:My opinion on the matter. (826 comments)

The whole "under 1024 is safe" is generally regarded for connecting *to* ports under 1024, not receiving connections from them.

It's only "safe" if you 1) trust that the machine to which you're connecting restricts the ability to bind to ports under 1024 (not guaranteed), and that the only people running processes on the machine in question are either trustworthy or are restricted from running programs that bind to those ports (not guaranteed), and that the system services you care about have ports under 1024 (not guaranteed).

And what guarantees that a "system service" (whatever that might mean) has a port under 1024? Perhaps a better scheme for determining whether to trust a service is called for here - one that would probably obviate the need for "privileged ports".

Yes, some services (NFS in particular) want to trust incoming connections from 1024 but they're in the minority.

One would hope that services that trust untrustworthy guarantees would be in the minority; in the best of all possible worlds, they would be completely non-existent.

If I was so inclined as to trust port numbers alone (and for the record, I don't trust incoming port numbers at all)

Good. Ideally, nobody would trust them, and claims such as "It prevents regular user programs from masquerading as system services, which usually sit below port 1024." would be treated as the uninteresting claims that they are.

Research Shows RISC vs. CISC Doesn't Matter

Guy Harris Re:There's a lot more going on... (161 comments)

The discussion was about adding more registers in a CISC architecture, and so CISC functionality is the context.

"CISC functionality" is the ability to execute a given CISC instruction set with acceptable performance. Transistors can be used in several different ways to achieve that, and you can choose to use fewer transistors in one place on a chip in favor of more transistors in another place, and if that choice means you still get better overall performance executing the same instruction set, that choice is a good one.

When you ask what "the same functionality means" that is absurd. You can't implement a subset of the functionality and still have the same functionality.

Again, as long as the full instruction set can be executed (even if some of it is executed by trap code), you don't have a subset. You may happen to execute some functions slower, and other functions faster, but if the net result is faster execution of the code actually run on the machine, you have a better implementation.

I'll put this in simpler terms. Smart people design CPUs and they don't add a bunch of registers even though that would be useful.

Smart people add registers iff they're sufficiently useful that it's worth either increasing the die size or taking transistors away from other functions.

The reason they don't do it is because of the additional chip real estate it would cost in an already over-taxed landscape, not because they are lazy or haven't though of the idea.

For existing architectures, the reason they don't do it is that it would require changes to the instruction format, which, for most instruction set architectures, would be a royal pain. For x86, they (AMD, to be specific) could and did add Yet Another Prefix to double the number of registers as the instruction set already had a tradition of adding prefixes. For ARM, they were already introducing a 64-bit variant of the instruction set, and didn't have to maintain binary compatibility. For, for example, System/3x0, you'd have to add prefixes to an instruction set lacking prefixes, or somehow use opcode bits to refer to additional registers. If somebody were to design a brand new CISC architecture (in an era where we're not designing many new instruction set architectures at all), they could design one with 32 GPRs.

Research Shows RISC vs. CISC Doesn't Matter

Guy Harris Re:isn't x86 RISC by now? (161 comments)

The AMD-64 architecture - is that also register limited?

With 16 GPRs, it has fewer registers than all the major RISC architectures other than 32-bit ARM, just as the 32-GPR System/3x0 (including its 64-bit z/Architecture version) does. It's less register-limited than x86, but that's not setting the bar very high. (Note that IBM recently added instructions to z/Architecture that do arithmetic on the upper 32 bits of the GPRs; that suggests that there's some register pressure with only 16 GPRs, although if they still have to make use of base registers, even with PC-relative branches, that might add some additional pressure that x86-64 doesn't have.)

Or did AMD toss something like 32-64 program accessible registers @ the problem?

No, they didn't; x86-64 has, as noted, only 16.

And if they did, would Intel have limited theirs?

Limited their what?

Canada Tops List of Most Science-Literate Countries

Guy Harris Re:ROLF! (221 comments)

Better than, say, the health care systems in the UK, Germany, France, Spain, the Netherlands, Switzerland, Taiwan, etc.?

there are a lot of shitty developing countries with healthcare that's much worse, and there's the united states.

There are a good number with better healthcare than Canada no question, but the number of countries with much worse or none eclipses that list

There's "the alternatives" and there's "the alternatives worth considering". The latter category excludes the developing countries in question, as well as the US. Hopefully the people in charge of health care in Canadian governments (federal and provincial) are looking at the alternatives in the latter category to see what they can learn from them.
