Oh well, at least now there is jurisprudence to put gun manufacturers into jail. After all, they make the tools that others use to commit crimes, which is what this guy is going to do hard time for.
Only if they're selling their weapons with full knowledge and intent that it will be used to commit crimes, but then this was the case prior to this guy anyways...
imo you can't really say 2.4 billion years ago. That would make sense only if there was one universal time scale with the necessary requirement of information being broadcasted instantaneously. Considering that it's not possible (hard cap of c), every point has its own time and events happen when information about them, spreading at the speed of light reaches said point. For us on Earth that dark matter stuff is happening right now.
Yeah, well, you're just speaking within your reference frame. In my reference frame, I'm located at a point equidistant in space and time from both this event, and you, and I see you responding to this event 2.4 billion years late...
Of course I won't actually see the light from you responding to this post until at the earliest 1.2 billion years from now... but since I can violate causality with my tachyon emissions, I've already witnessed your observation, and response, and responded myself....
All that aside, I was going to post that it happened "2.4 billions years away!" but I was afraid no one would get the joke...
Not really. He said we're 200 years into a 1000 year cycle of reversal. That means we're 1/5th through it. So they would point 1/5th of the way to south.
If the PP is even correct, which I am neither arguing for or against.
Oh, I get what he's trying to say now. However, it's just plainly not what was said. "A 1000 year cycle of reversal" says that the reversal cycles every 1000 years, and that we're 200 years into the current cycle. (So, the poles should reverse in 800 years, and immediately begin reversing again.)
This is different from "200 years into a 1000 year pole reversal process, which cycles every X years."
Regardless of how one might concoct a diagramming of the phrase (even in wrong diagrams!), the phrase still comes out to mean a 1000 year cycle, which gives a period to the cycle of 1000 years.
The crosswise definition of "cycle" being used can be best demonstrated with: "we are 2 days into a 7 day cycle of lunar waning."... wait, what? "Lunar waning" is only a part of the lunar cycle, and while it does last 7 days, it's not a cycle itself.
We're 200 years into a 1000 year cycle of magnetic pol revrsal.
This would mean that 200 years ago magnetic north was oriented with the axial south. This would mean that all compasses built more than 200 years ago would point south with the north end of the needle.
Considering this would be significant, and this patently easy to demonstrate, yet is patently false... would you like to try again?
On x86, the division instruction also calculates the remainder. So (year%100) will give you year/100 with zero instructions. Since division and modulus are slow, it is much faster as originally written.
*fiddles around with some gcc -S...*
Yep. You're right, I hadn't thought of that.
Although, since this is all boolean math anyways, the ands and ors are typically dealt with by using flow control anyways... since the "||" short-circuits the division entirely, both versions will run at the same speed 3 out of every 4 years. And the !(year % 100) would short-circuit the "&&" for all but every one-hundred years, so the only time that the speed difference would have made a difference was in the year 2000, and will again make a difference in 2100, and every hundred years after.
So, indeed, it is faster, but not really an efficient use of time to optimize...
Weirdly, when I compiled without any optimization flags on the command-line, it turns the idivl into a few imull's, with some shifting, and subtracting...
Having experienced this while working in radio during my college years I can state that it is EXTREMELY difficult to speak while hearing your own voice back in a delayed mode. This was often done as a practical joke to experienced radio announcers, and the only way to effectively continue to speak was to remove or mute your headphones. Several people have pointed out that wearing earplugs or even just sticking your fingers in your ears would allow you to continue to speak, although that is difficult as well since you may speak too loudly or softly without hearing your voice. I doubt that anyone would be able to adjust easily and still come across clearly and eloquently if they just tried to mentally mute the delayed feedback.
There was a friend of mine who was in marching band, and he said he once played in a stadium that sent back a delayed echo, and that really screwed things up. It definitely is not a normal stimulus that we're used to dealing with, and it can definitely befuddle people, but it's not extremely debilitating.
However, it really just takes some good practice, and a confidence to keep speaking while just trusting that what you're saying is correct.
"year % 400" will execute in the same time as "year / 100"...
I wouldn't be so sure. AFAIK x86 CISC is actually RISC + macros, so MOD is actually DIV + MUL + SUB, therefore slower than DIV + ANL.
... no, it's not. DIV and MOD can be calculated at the same time. And in fact, the most efficient way to calculate a quotient (short of a hardware lookup table) in circuitry actually does calculate the two at the same time.
In the x86 architecture, it is defined by the Instruction Set Architecture that the DIV operation calculates both the quotient and modulo at the same time.
My bad - meant to type III. Keys seem to be sticking a bit today...
Eh... even then... the G4 did far more per cycle than even the Pentium 3 did... plus it had a full SIMD set that exceeded even the SSE3 standards.
I had a G4 PowerBook at the time, and I regularly compared the processor to twice the MHz on the Intel side... meaning my 500 MHz laptop was performing about as well as my 1GHz Pentium 3. And then the Pentium 4 was really half the performance per MHz from the Pentium 3, so that puts it as essentially equivalent to a 2GHz Pentium 4.
So, really a 1.4GHz G4 compares really only well against the Pentium 4...... All this being of course entirely just pedantry... the machines are regardless still crazy old.
Unless there is a bug in the "same basic standards" that the heterogeneous systems use...
Ah... like the WMF exploit... I was explaining to someone at the time that the problem with the exploit was that it was functioning exactly as designed and intended. >_
According TFA all the "jammer" does is play back a copy of your speech delayed by 0.2 seconds, akin to being annoyed by loud echo on a VoIP phone or Skype conversation. While echo can sometimes be annoying when it interrupts yourself, it is fairly easy to adjust if you've done it before and talk over yourself. Because the gun features both a directional microphone and directional speaker, if you can comfortably talk over yourself everyone else will hear you just fine, sans echo.
Looking up Delayed Auditory Feedback, it's been long used to help stutterers to produce fluent speech. It causes them to speak slower, but they also speak more fluently.
I'm with you, this does not actually stop speaking, it just makes it annoying and stressful to speak, but a lot of people won't suffer any impairment in dominating a conversation even with this device.
(the original word in Genesis translated as "day" was more accurately "a period of time" although it was often "day" but not necessarily
Yes, and so Yom Kippur is the "period of time of atonement", rather than the "day" of atonement?
Plus, the first mention of "yom" in the text is "God called the light 'yom' and the darkness he called Night. And there was evening and there was morning, the first 'yom'."... it's kind of hard to argue against a non-literal interpretation of "yom" as "day", when clearly the first day was a single cycle of evening and morning.
No, it doesn't... just most of the digits turn to "0"... in fact, the remaining radial digit of the number representing the year will not be a "1" either, as in when we moved from 99 A.D. to 100 A.D. No, in fact, they were already on the 12th cycle, so the calendar already could express more years than just 2012 A.D. and we never had to add anything to their calendar system to do so...
You do realize that at least on the x86 architecture that "year / 100 & 3" is two instructions, while "year % 400" will execute in the same time as "year / 100"...
I knew Command Riker was "Will", but I thought Lieutenant Riker was "Tim", which I guess is short for "Thomas"... but basically, I would have, but I was too lazy to check that I would be right... I know, barely a moment on Wikipedia even, but seriously, there's an incredibly amount of lazy up in here...

I have found that macs purchased in the last four years to hold up less well than macs purchased fourteen years ago.
(I know, four data points is barely statistically significant, but that has been my experience.)
I can buy that the quality has gone down in recent years. Especially since they switched away from PowerPC...
But then, I have a soft spot for esoteric technologies...
Japanese has an especially low information/syllable density (and thus is spoken rapidly)
Huh... I've never heard of this phenomena... do you have any links to material supporting the claim?

Actually, Macs hold up quite well against time. I don't expect that the eMacs are having any trouble at all with stability.
I do however, expect that they're insufficient to the tasks involved, and need to be replaced.

Prostration is the placement of the body in a reverentially or submissively prone position
Look at the picture. Obama's being submissive. If there's any doubt left, watch the video and the reaction from the Saudi King.
Dude, seriously... can you not read? Keyword here: "prone". I watched the video, and I didn't see Obama "lying face downward" on the floor.

NOPE!!!!! Tim is short for Timothy. Tom is short for Thomas. **mind blown**
See? It's a good thing I didn't post it, otherwise I would have totally screwed it up.
Of course, I just later posted it anyways, showing how dumb I was, but showing how smart I was to know how dumb I was, which was kind of dumb.
