Depends on your area, and what's in your cell. In Cali, there are two call centers (norcal, socal), staffed by CHP. All mobile 911 calls go there. Then they'll forward you from there to a local dispatcher (if you're lucky). There can be a bit of a wait.
A landline call is routed directly to the call center (by the telco's CO, I beleive).
So while yes, the cell phone knows exactly where you are (better than gps with a CDMA phone), and sends that to the call center, the data often just falls on the floor. Of course, if you're calling from a car, driving down the highway, your location quickly changes.
So don't call in an accident without stopping at it. It just wastes everyone's time.
"land-lines" have a major advantage over cell phones (at least in california). Here, if you call 911 on a cell phone, you get forwarded to one of two CHP call centers, they can be massively swamped during rush hour, and really have no idea about your area.
A land-line 911 call, however, goes straight into your local fire/ems dispatch center, and they usually respond faster, respond the right engines/ambulances, and even get the roads right.
I do have to agree with your comments. I agree that other OS's can have software added in bad ways. What I would prefer to see is that the OS's that I run, never allow any install to occurr without me personally OKing the operation. Maybe that would be obtrusive, but that is what I would wish.
My mac does this... Anything requiring admin privs asks for the admin password.
The 600+hp diesels are actually daily-driven, and reliable, but the cummmins block itself is rated for 1500lb-ft of torque, so that's not your limiting factor for a LONG time. You can get up to that with just a big set of twins and a fueling box. (some of the drag-racers I know also tow with the same truck).
Seems like most of the smaller engines are swithing over to VVT more and more, but there it gives them the low-end torque that they just don't have, with the high-end that people expect them to have.
But even a 350hp v8 using VVT could have a dead-flat torque curve, and a LOT less displacement that the current drop of engines (5+ liters? yeesh..), with just as much reliablility. And insurance wouldn't care.
Applying the VVT to the big engines would definitely net you some high HP numbers, but it's just not needed.
What I like with the VVT is the power is there, but if you don't need it, you're getting a hell of a lot better mileage, as the cam can be adjusted for a more economical setting on the highway. But blip the throttle, downshift, and the engine opens right up and starts screaming.:)
Just getting variable valve timing in a truck would be nice. Both your low-end grunt AND your high-end HP.
trucks should just only come with diesels, unless you're the lowered-drag-strip variety.. oh wait, they drag-race 600+hp diesel trucks, too...:)
My 350Z has a torque curve that my truck covets. Dead flat torque from 2000rpm to redline (6600 rpm). Peak torue is a bit lower (275 vs 335), but I forgive that from a 3.5L V6 vs. a 5.9L V8.
I have that CD. Liner notes state that they blew out windows 100 yards away with the largest of the cannon blasts that they recorded, and that the recording goes down to 6Hz or so.
Utterly amazing recording (for demo purposes), but most systems just cannot handle it.
Agreed that FFTs are best done in DSPs, but when writing an app that runs on x86 platforms, that's not much of an option. And for a scientific (or design) application that heavily uses FFTs (speaker design, for instance) you want the precision of doing the match instead of estimating things.
From a cpu-cycle approach, how sensitive was the processor to byte alignment in structures? I'm not familiar with PPC assembly, and haven't done the calculations on x86, but am familiar with other CPUs (mostly older) that were sensitive to the tune of an extra couple cycles per instruction to do the internal shifting of data. Granted, these were also non-superscalar chips that didn't have the kind of pipelining and out of order execution available to a more modern processor.
By tweaking the innermost loops for the cache hits, I was thinking data-size and not code-size. Although if you overly unroll your loops to the point that parts of the loop fall out of cache... I was also thinking of large blocks of data, with semi-random accesses (as opposed to sequential), say when logically processing array of data vs. arrays of numbers. Again, this might be moot with megs of cache on-chip.
I wish I had the time to go craft up some scenarios and really sit down and look at the results...
However, if you have algorithmicly intensive software (spending lots of time in the same loops or crunching large amounts of data), it's worthwhile to instrument your code and see how you're doing for cache hits/misses. You might discover that by tweaking the inner-most loops or the size blocks you crunch, you can better fit the cache of the target processor.
Word/Excel isn't going to bother, but a game might be worth stuffing a few versions of tweaked loops in that are selected by a loop invariant, or by feeding the functions some data ahead of time to help guide them to use the best sizes of data that they can.
This isn't unlike memory alignment for structures, and taking a massive performance hit for the data not being "easy" for the assembly instructions to process.
One example is the ability to loop-unroll the innermost butterflies of an FFT on the x86-64 extension using the extra registers that are available there. That WILL get you a noticeable increase in performance.
But these are always the last 20% kinds of increases...
I'm certain that people with Cancer would fall under a protected class via the ADA/Civil Rights laws. And since the only change that would have to be made to accomodate the person would be to bend a rule (no spendature of money required), then that person would have a viable case to sue if booted.
(just covered this stuff yesterday for work.... it was thrilling, lemme tell ya).
Blogging doesn't neccesarily impact activities "in-school." You're not reading/writing your blog in school, nor are your comments taking place, in school, even though they might be about school.
And slander/libel issues aside, there's no guarantee of privacy for the school, that what happen within it's walls is secret and not to be publicized.
short haircut policies do impact the school directly, as one cannot have long hair at home, and short hair at school (naturally).
Boarding schools are greyer, because if the students wanted to blog, they'd almost have to do it from school (dorm rooms). Yet again, I think that even a non-state school can legally surpress a student's right to free speech.
Although being a minor, free speech guarantees are a bit more vague (from my recollection of things. The whole minor's not being real people always irks me.)
I think once we entered their country, we can't call them terrorists for attacking us. Guerillas, perhaps, but then, look to our own past, 1770s or so, attacking the uniformed redcoats marching from town to town, from behind the walls, dressed in the drab clothes we had.
There may be domestic terrorists there in Iraq. If so, they're attacking other (civilian) Iraqis. We've had domestic terrorists here, Oklahoma City.
We've had foreign terrorists here, World Trade Center, lots of planes, etc.
But once we showed up in Iraq as a military presence, any attacks by Iraqis there, against our military, aren't terrorist attacks. They're not attacking civilians, they're attacking foreign invaders. And frankly, they've got a right to do that as far as I'm concerned. We've got to figure out the right thing to do there, but when we marched in and knocked down the military there, we also had to knock down the civilians who agreed with it. And calling them terrorists when they are defending their home against foreign invaders is pretty pathetic.
I think the green-house gas neutral aspects of biodiesel (especially when made from algae, which is MUCH more efficient of a plant for carbon-sinking than soy/canola is) really needs to be showcased more.
We can spread algae ponds throughout the country to create a distributed production system for biodiesel, which can sink as much carbon as goes out the tailpipe, because the algae needs the C02 in the air in order to grow to produce more biodiesel.
Right now we're pumping carbon out of the ground, and throwing it into the air. As long as we continue to do that at a rate that's faster than all the plants in the world can sink it back down into the ground, we're in trouble. However, we also have this tendancy to cut down all the trees, all the rainforest, all of everything, and build concrete/asphalt cities instead.
Luckily the oceanic algae are the biggest sinks of carbon, but we're mucking with ocean temps now, and that affects their growth rate (not necessarily positively).
Treat it like a semi-closed system (solar input, radiated heat/light to space, most chemicals are staying right here), and we'll be seeing better ways of managing our resources.
If I don't change the "dpi", then going from 800x600 to 1600x1200 is 4x the screen real-estate. And my eyes are good enough that I can read that easily.
That being said, I've found that I can handle a much lower resolution on macs than on PCs. The different layout of the GUI makes it easier to see more on the smaller screens. But coding at 1024x768 is still not fun. I'm used to 16x12 and larger.
1) Vitamin-D(or E?) generation due to sunlight exposure 2) circadian rythm timing based on sunlight exposure
For a geek, what they really need to do, if they want to actually be able to function in the rest of the world (instead of rom noon to midnight+), is to expose themselves to roughly the output of a 100W lightbulb for a period that matches up with when the sun's out. Which means that after the sun goes down, you dim the lights down. This way the body understands what time it is. If you have lights on bright late at night, you'll slowly shift your circadian rythm later and later, getting up later and later each morning...
Total darkness at work doesn't help, either. The body uses sunlight to figure out when it should be awake/asleep.
Then if you're not getting enough light exposure (real sunlight), your body won't properly produce one of the vital vitamins, and depression will start to set in (anyone can become Seasonally Affected if they don't get enough sunlight, for a long enough period of time).
Ever notice how GOOD sunlight can feel sometimes? That's the body soaking up the UV for vitamins. Always being slathered in SPF40+ will actually cause the same problem, you NEED sunlight.
Dement wrote an excellent book about this (pioneer of sleep studies at Stanford).
Nah, aluminum's pretty light. MUCH lighter than steel. My powerbook as an aluminum/magnesium case, and aside from the battery, doesn't weigh much at all.
CDMA vs. GSM. GSM's use of sim cards is inherently more "open". The card is really the identity that authenticates on the network. The ESN's used to identify the PHONE on CDMA networks is what gets locked. The big CDMA networks actually have a database of all the ESNs of all the phones they've bought from the handset manufacturers. Not in the db, no service. Even if you buy an overseas CDMA phone, since it's not in their list of "valid" phones (serial numbers, not just model numbers), it's a no-go.
2) You print material isn't supposed to be seen by anybody else.
Then you should be using a pro/semi-pro lab. They'll do amazing quality prints, and they'll be professional, which means that unless it's outright illegal, they only inspect your prints for printing quality.
I've not had any issues at all with semi-nudes/nudes at my local lab, but it's not wallmart, either. I know the people there on a first-name basis, and high-end lab I use for lightjet prints is very professional, and geared towards pro photographers that are doing lots of "art" photos.
The new phones that I've seen, when I recently switched providers, all appear to be running custom firmware for each provider. So, in essence, while you can get phone A hardware for 2 different networks, the software is more than locked to one of those networks, it was written solely to work with that network.
But this is probably also to do with the way CDMA works vs. GSM. The CDMA phones do data differently on different networks, so when a sprint phone roams digital to verizon, no data, and vice versa).
GSM, having a real data standard, seems to not have this problem.
And yeah, being hero is a great way to screw things up.
We're told to never freelance (go out on our own), and that our first priority is our own safety. Because if WE go down, then minimum 2 other FFs are going to be needed to pull us back out to safety (4 is more likely).
A FF down is a situation where everything halts until the status of the FF is known, and if they're safe, then things continue.
Yeah, I noticed that... They're a bizzare little company. And they need to completely replace thier marketing department, but they make (or did 5-10 years ago) some really nice headphones.
They might have simply decided to change some compiler flags that will yield incompatible binaries (gcc has a ton of them).
Nothing meant to stop piracy, just a different methodology for making calls, etc. Changing the default style for sending parameters, use of registers for arguments to leaf functions, etc.
When I moved out of silicone valley into the nearby santa cruz mountains, I was amazed at how much of my hearing seemed to come back. Much like there was a significant amount of mental filtering taking place.
The ambient noise level being lower contributed immensely for hearing sounds when at home (especially since I don't have any forced air heating/cooling in the house), but I also noticed that I have a far lower tolerance now to high noise environments when at work. I can hear more of the noise when at work now.
If you have problems with the constant pressure, you might be out of luck.
If you want good headphones, but don't mind sound leaking in/out, then I'd recommend an open-air set like Grado makes. I have their 125s. Half the price of the Bose noise cancellations.
I find that it's both easier to listen to the music at moderate/low levels AND I can still hear enough of what's around me to not get snuck up on at work. Although it's still easy to filter out (mentally) the noise around me. My officemate, however, didn't approve of being able to hear the cymbals continually leaking out of the headphones, so I had to switch back to my denons, which are significantly more fatiguing.
Take a listen to them (if you can find them). Although they may not be what you need due to the open-air nature.
I've also found Koss to be relatively equal to Bose in build quality, higher in sound quality, and WAY cheaper.
Sennheiser has definitely gone downhill in the last 5 years or so. Their new models aren't at all like their older ones.
Being able to "flood" a room (or series of interconnected rooms) with a roughly continual level of sound. Newer houses with lots of vaulted cielings and open spaces do well with them.
They aren't in any way shape or form flat response curves, or have any stereo imaging to speak of, but for purely background music in a house, the direct-reflecting aiming works out well.
I'd not buy them, though. I'm working on building my own for about $500 or so right now. For that, I can get something akin to $2000+ or better speakers, but the price I pay is the time to get the cabinets well constructed, and the crossovers tuned properly (major PITA).
