does anyone know where can I download huge versions of these kind of images? I always wanted to make a poster, I thought of getting a big enough one to make it 300 or 600 dpi at a large size (at least 1 meter width), and have it printed.
You know, using your brain once in a while won't hurt either. I see the guys at my class using calculators for dividing 5/2, sqrt of 16, sin(30) and ln(1). Just because it's really easy to type them on your calculator doesn't mean it's faster or simpler than recalling it from memory.
Back to topic, try HP calculator's way of entering equations. I don't know if any computer software accepts input like that (don't see how, as the HP's keys are labeled), but it beats the crap out of anything else. Both in Equation Writer mode and in RPN (I use RPN).
Anyway, it's just stupid to take MATH notes in the computer in real time. Just, why? Before you answer think about this: equations have to be solved by the student (not bt the computer, CAS, Mathematica, Matlab, FORTRAN...). How are you supposed to solve them if not on paper?
oh, I get it now, i thought GPS was pretty overkill for this app. the good thing about it is that you don't need the external sensor and wiring. that's a big bonus. I was thinking of doing it with a microcontroller... guess someone beat me to it:D
anyway, I use a photoelectric in series with a timer (like $10 and with a nice LCD display, time, DST, etc). 16 programs (8 on, 8 off).
got a pretty complicated setup: ON every day at 5PM for the window lights, off at 0:30 mon-fri, off at 2AM sat-sun (so friday and saturday nights, when people go out, my window display is on).
another timer for the outside lights, mon-sat on at 5PM, off at 8:30PM. (my shop, a comic book shop, mind you, is open till 8:30 PM)
so all lights are on at 5PM but they actually turn on when the photoelectric allows them.
lol, all that high tech for just 2 35W halogens and 2 70W metal halides... I think the timers would pay for themselves in like 10 years. if they do last that long.
my argument is valid, it's just that you don't want to give in to anything, just keep arguing with crap like "my daughter is expected to perform blah blah blah " bleh. your daughter has (or will have) a calculator, people in the 60s had slide rules, before that they had to do calculations by hand and look up tables. when they teach calculus in grade school i will take your argument. but for now it's just crap.
the rest of the rant was about food. and i stick to it. the cause of obesity in the us is that people eat too much. stop eating (make people at least try to) and you will solve the obesity problem
so losing time learning handwriting is to blame for low grades in math and science? wrong. try again, smartass.
most of the science in this century (space travel, nuclear energy) was developed way before the widespread usage of computers, when people did a lot of handwriting.
the US is falling behind in math and science because there is no war (or cold war) to fuel development, it's as simple as that. it has nothing to do with taking time off from things and use it on others.
free world and all that crap, but it's pretty clear that the government NEEDS to push people to make them progress. free market is nice and should exist, but if you let it control everything, you end up in Idiocracy.
also, this is why you people are morbidly obese. hell, (and this is not just a gratuitous bash to the US), you people are disgusting (in the way you eat). The only country in the world that has SO MUCH space in the market for junk food is the US. Down here we have just plain Oreos, chocolate-filled oreos and that's about it. How many variations of Oreo are there in the US? How big is the "big" pack of oreos (here is just one size, standard). Chocolate covered oreos? We had them. but not anymore, people here just don't like to eat that many calories.
Here's an idea to avoid obesity: DON'T FUCKING EAT ALL THE TIME. I'm surprised to watch american TV series and movies, and notice that everyone is eating something. Donuts, cookies, sandwiches, junk food. All your society seems to revolve around food. Even your breakfasts are disgusting to us (I talk to some friends sometimes about the american breakfasts and they all agree). How can you people eat SO MANY fried eggs and bacon EVERY MORNING!?
It's just a society issue. Other countries have higher purchasing power than you, and they don't have such high levels of obesity.
what if the rope was completely non-elastic, weightless, and standed completely near the oceans surface (meaning the rope was following the earth's curvature), and the ocean and wind were completely calm around the length of the rope?
Considering how little free time people have anymore, it doesn't make sense to waste one more second than you have to on reading.
That's a load of bullshit. Make people ditch their Facebook, IM, PORN, TV and XBoxes and you'll see how much free time they have.
But my point stands. You learned to write in cursive, and also in print. For you, print is good enough. And you have a skill that you won't forget.
Seriously, what's the big deal? So kids have to "spend time" learning to write cursive. What are they missing anyway then? What do you have to teach them in that time they're "losing"? If they have to do cursive homework, what's wrong? What would they do if they had to do something else? Play videogames? Spend time online? Yeah, skills for life.
Seriously, reading through the comments you see a clear hate against handwriting in general and cursive in particular. In fact, I'm amazed at how american people can't write in cursive. Here in Argentina it's the only thing you learn (they don't teach print at school).
I think some things shouldn't be left as an option. Proper handwriting (as opposed to "just good enough print") is one of them. Also, decent math. In the last 20 years education has changed here. It's no longer the one-size-fits-all curricula for grade+high school (technical school had a different curricula). Now, at about 13 years old you're forced to choose between "social sciences" and "natural sciences" (no career aptitude test). So most kids go into social, cause there's no math in social!!! How cool is that!!!. And I see them in college (computer degrees), struggling to do even the most basic operations. Can't even think about fractions. The guy next to me has to use his calculator to figure out how much is 1/3. And he asked me for a pen one time. I use a fountain pen... he had no idea how to hold it, had to show him how to hold it and he was amazed that the thing writes without pushing hard on the paper. And they spend so much time doing stupid calculations on their $5 Casios.
I don't know how people do stuff in developed countries, but I'm pretty ok with my paper notebook (which lasts for about 1 year) and my Parker Vector fountain pen.
Yes. I use a fountain pen, a paper notebook, and an HP calculator in RPN. I must be a fucking luddite.
when I mentioned SSD caching I was talking about the regular "business" reads (not the "rebuild" reads).
you mention RAID-Z2, that's a completely different animal. but yeah, that's what it's for: the chance of a second drive failing during the rebuild, which RAID-5 doesn't take into account (pretty much, the main topic of the original post was about a second drive failing)
so if it takes you days to rebuild an array you're, statistically speaking, much safer and it won't matter if it takes a couple of days to rebuild, it will become an issue only if you're near 100% I/O usage (which is rare 24/7)
DAYS to rebuild an array? WTF? I have an old athlon64, 3GB RAM (running at DDR200 instead of DDR400 because of a stupid memory controler, not even dual channel). Motherboard is a regular ASUS board, and its running OpenSolaris (some 1-year-old build). It serves silly services for internal network, but also runs 2 VMs (VirtualBox) which keep the cpu and RAM moderately busy most of the time. SATA drivers are Sun-provided-never-updated drivers
ZFS (software "RAID") takes about 2 hours to rebuild ("resilver", in zfs's terms) the 4x500GB array (90% full). I'm pretty sure that if the controller was SATA2, and I had more RAM (ZFS keeps huge caches in RAM -- by default "system memory - 1GB"), a second level cache (an SSD drive), and more up to date hardware, things would go much faster. I don't know why people keep telling that the array would take days to rebuild.
Probably only if you're near 100% utilization on disk I/O it would take you that long, but provided that ZFS can make caches from RAM (you can easily have 24GB on the newer Core i7 boards) and SSD (which would give you some 256GB of extra cache), I don't see a situation where it could take that long (or probably yes: if you run a program to read random sectors, effectively making cache useless).
thats exactly what I was thinking, no one in the thread noticed that.
maybe he should have used another metal? stainless steel pipe maybe?
also, will copper tolerate the mechanical stress? i'm not sure about that, maybe if it's one piece it will. hope they're not using cement additives, maybe those will react with copper too.
Here we don't have many black people (black as in african, but there are dark-skinned people). So it's weird here to see an ad in which a black guy is just "sitting there". you don't see that in the office. the ad is supposed to be something people can relate to, and if you're not used to seeing black people, you find it weird.
should microsoft make a different ad, featuring white people, for poland? probably. should they photoshop-out the black guy? that's pretty lame really.
that's what I was thinking. does each segment draw more than 20mA? if not, you can forget the transistor and resistor altogether, just hook up the filament to the output pin, if you use Microchip PICs. they can source or sink current.
anyway you say that you need 3VAC for the filament. how are you driving it? transistors don't work both ways, with that circuit you're rectifying AC. I think you need both an NPN and PNP to make the full-wave go through.
Use Xilinx's FPGA Starter Kit. I bought the old version 5 years ago, and it also came with a CPLD dev kit. The dev tools run on linux too. It was something like $99 IIRC. It's made by Digilent. Last time I checked they had a better board for an extra $50 with an LCD display and 64MB SDRAM.
Otherwise, check fpga4fun.com . They use a tiny FPGA board, which reminds me of the Arduino: it has everything you need and nothing more.
oh, no, not this shit again. fucking commies. dude, get over it: communism only exists in books. Cuba, the USSR, China, whatever. all of them tried to be communist countries and failed. I don't get why you communist claim that everything we know about communism, isn't. What are we suppossed to do? Vote for you to show us what it's really like? How do we know you won't turn out to be the same?

read the post. the array is 4x500GB (being upgraded to 4x1TB), 90% full. still takes 2 hours to resilver.
But they also host google mail and apps. The data on that can't be regenerated.
DAYS to rebuild an array? WTF?

easy.
put the computer on an airtight container, and throw in a lot of silica gel bags. no humidity - no condensation :D
