there is a thread about technology help here http://tohno-chan.com/mt/res/131.html

why do you make a whole new thread dedicated to a simple google search?

Ipod is horrible for reading manga.Get the only worthwhile item for reading like a Kindle or a tablet.

I finally remembered this thread I created. I had to replace some hardware and upgrade to Snow Leopard, but I got my Mac running everything I want it to (Wine is a gift from the heavens). No stuttering problems with F/SN like I had on my old laptop. Here's a list of pros and cons I've come across while using my MacBook:

Pros:
1. Pretty UI and build
2. Almost no compatibility problems
3. Apple goes to great lengths to make OS X easy

Cons:
1. So little freeware it hurts
2. Apple thought it would be hilarious to lock this model's HARDWARE from accessing 64-bit mode. What the hell, Apple?
3. The average Mac user doesn't know anything about their own OS. Needless to say, the community is of little help with problems you can't lol point n click away.
4. fdisk has been mutilated to the point that I'm not even sure how to use it.
5. OS X gives me a big FUCK YOU whenever I try to boot from a USB. Someone tell me of another OS that doesn't let you boot from a USB! What the hell kind of shit is this!? This pisses me off to no end!

I will be installing Ubuntu on my MacBook. I can't deal with how unfriendly this OS is to people who want to do tasks beyond media editing. I wanted to believe people were exaggerating when they said OS X was restrictive. I believed in the goodness of Apple. I was wrong.

What the hell is it with Apple taking ownership of all the products they sold to you that you supposedly "own"? That is my number one issue with them.

I wish I could take a diehard apple fan's keys, make a copy, and then send a team of Apple people in to rearrange his kitchen drawers, the layout of his furniture, the colors of his walls and all the outlets his appliances are hooked into, because that's the way Apple does things, and, from now on, that's the way he is going to do things as well. And every time he loads iTunes, the team is going to come in and fix whatever he's changed in his house.

Something tells me he'd welcome it.

>>1199
While I can understand Apple wanting to idiot-proof their system, they should provide a key for all the locks they put in place. Deciding absolutely on what can and can't be done is tyranny, especially when their customers pay so much to own, not borrow, one of Apple's computers.

I think you might find better guides on www.google.com than here on Tohno-chan.

Just don't use simple tap water for your watercooling, please.

Do you really need water cooling, though? I mean it's pretty obsolete these days. Even if you OC your hardware, you should have enough airflow in your case that it can keep the thing cool. Water cooling was useful like..early 2000s when chips were getting a lot better.

That said, check this out. Did you know you can essentially submerge your system in a tank of cooking oil to cool it? http://www.tomshardware.com/reviews/strip-fans,1203.html

You can't really change the settings in DOS or your bios to overclock something, they set your processor at optimum levels and don't let you change it. You'd have to get a program that will hack your CPU to change it's clock speed.

>>721
Actually water cooling is still used, and is pretty common in high-power rigs.

>>732
Actually, as far as I know you can change your FSB speed in your BIOS to OC most modern CPUs, except Intel's sandy bridge.

The cheapest you can get with usable new mobile computers is probably this ARM-based smartbook for $199:

Battery life is claimed to be 7 or 8 hours, IIRC.

Other than that, I'd suggest simply getting another EeePC of a newer generation.

>>7387
Ohh, that sounds cool, but whats with the 3G thing? Is it like some free deal like with the Kindle? It does not say anything about subscribing to ATNT for service on the site.
3G/GSM would be really good for me because I want to replace my old one for the purpose of traveling.

>>7389
Sorry, I don't know anything more about it apart from what's on the web site, and I didn't even read all of that.

Also notice how it doesn't have any built-in connectors for external displays or wired LAN, might be an issue.

well this isnt new they just proved it - the idea of gravity influencing space. That's part of the stuff that happens around black holes...

Trust me, a community college is much better. Because a degree from Devry does not mean shit to employers. In fact, it's practically worthless as employers take any resumes or CVs with any mention of a for-profit school and just throw it away or ignore it. (It's really better to not mention ANY for-profit school at all in a resume/CV.) And you'd spend less money at a community college compared to Devry. At least you'd get an associate's degree from a community college.

Yes, DeVry, like most for-profit schools, don't offer good education and your money and time is far, far better spent at a good university.

Will be attending the Zenos IT Academy starting Feb 28th. My secondary school left me with lots of nice little crappy paper qualifications, but no actual skills.

I'd prefer a career in music (bassist) but it's not stable enough. I could see myself doing a lot worse than IT, so I'm jumping at the chance. I find computing in general fascinating anyway.

>>167

I agree.

I don't know if anyone else here is into game programming like I am, but a guy from /v/'s game dev threads has been maintaining a server with resources on the subject. It's at deeserver.wmclan.net if anyone wants it.

2.45+2.45+2.45+...(368 times)

Then move the decimal place two places.

To move the decimal place x times you have to divide by 10 x times. To divide by 10 you have to multiply with 0.1.

Fuck. It's impossible.

>>270
Multiplication is not repeated addition, at least when it involves non-whole numbers. That's just something that elementary school teachers teach because it's easier for kids to "understand" even though they're not really understanding it on a conceptual basis.

There's a reason why it's one of the 4 elementary mathematical operations. Just go google "multiplication is not repeated addition" and you should get a lot of hits.

So to answer your question, it's impossible.

>>274
>There's a reason why it's one of the 4 elementary mathematical operations

On a second thought, I'm not sure if this is correct. I think most(?) mathematicians consider there to be only 3 basic operations (addition, multiplication, and exponentation) since subtraction is just an inverse of addition and division is an inverse of multiplication.

I heard about this from by brother while we were talking about a week ago.

I hope this encourages an effort towards faster transition.

ipv6 is nowhere near ready for actual use.

It should be starting now where I live, but the moon still looks clear white...
I'm downloading shit now, so I'll still be awake for a while; will confirm when full eclipse is visible; would take pics, but from a cellphone? nah.

Raining. Hard



I'm actually quite frustrated considering I've been looking forward to this for months. But of course I'm never able to experience these things

Almost completely covered from where I am right now, pretty awesome.

JUST CONLUDED, in here. Really pretty; made me think about Lilith's Red Moon...

Anyway: my download have just finished too, so I'm gonna watch it. Have a good winter solstice, everyone; glad to have spent this (weird) seasonal year with you, brohnos.

If he wanted to only mean one specific Fox viewer he should have said "a certain Fox news viewer." "A fox news viewer" refers to the generic Fox viewer.

I assumed he took a quote from the Fox News website or one of those shows where people submit comments like Bill O'Reilly's, maybe I'm wrong.

It basically substitutes phosphorous as a building block for organic molecules. So it's not that surprising at all, since both phosphorous and arsenic are within the same period. It basically has the same function as phosphorous in these cells, except that it's much bigger than phosphorous. But that discovery also shows how extraterrestrial life could be radically different than living organisms on Earth.

Part 3: Dislocations and ways to make metals stronger

Part 3(a): What dislocations are

Dislocations are essentially 'imperfections in the crystal structure'. The atoms in a crystal do not always line up perfectly, and there may be some abnormalities such as a missing atom or an extra atom which distorts the pattern of the lattice. Dislocations can travel through the crystal along 'slip planes' using a caterpillar-like motion. Diagrammatically, we use a perpendicular symbol to depict a dislocation. A typical engineering alloy will contain 100,000km worth of dislocations per centimetre cubed.

Dislocations may or may not be wanted in a material, depending on circumstances. Introducing more dislocations into a material tends to set up a 'forest of dislocations' which causes dislocations to get tied up in one another, stopping them (and the slip plane) from moving. This makes a material hard, but at the same time makes it more brittle and inflexible. Hardness might be desirable in a bridge girder which you don't want to wobble, but undesirable for steel used in springs.

Part 3(b): Intrinsic lattice resistance to dislocations

For a dislocation to move, it needs to break and reform a bond between two atoms. This requires a force, and this resistive force is called the intrinsic lattice resistance, symbol Fi. Dislocations move when the slip planes slide over each other.

In metals, Fi is low because of the non-directional nature of the bonding which means that the atoms don't give a fuck that they're sliding. In contrast, ceramics have a high Fi because bonds between atoms are highly directional, and breaking one bond to move a dislocation implies breaking fifty million other bonds on the slip plane too.

Part 3(c): Making metals stronger

In this section I will describe some techniques used to increase the overall lattice resistance of metals, and hence stop dislocations from moving. The movement of dislocations is the mechanism by which slip planes move, and on a macroscopic scale is 'bending' which is often undesirable.

Solid solution strengthening: Is basically 'alloying'. Consider this: with water, you can dissolve sugar into it and get a solution of water with sugar molecules interspersed through it. With metals, the same is true: you can 'dissolve' molten zinc into molten copper and receive a 'solution' of both.

How does this inhibit the movement of dislocations? Solid solution strengthening introduces impurity atoms into the crystal lattice. These impurities have different atom size compared other atoms, and so they distort the crystal lattice. Dislocations need more force/energy to move past these distortions. Two main factors are responsible for the increase in intrinsic lattice resistance: difference is atom size and the amount of impurities added. Copper and zinc have fairly similar atom size, so there needs to be a mixture of about 30% Zinc to 70% copper. Carbon and iron have a huge difference in atom size, so only 0.3% of carbon needs to be added to the Iron to get the same effect.

Precipitation hardening: Let us carry our analogy with sugar and water further. If you add lots of sugar to hot water and dissolve it all, you may find out that some of the sugar recrystallises out of the solution when it cools down. The same thing occurs with metal alloys. Some impurity atoms will 'precipitate', forming small particles of impurities inside the matrix of the alloy.

These precipitate particles impede dislocation movement. Dislocations are forced to either go around, or cut through these particles. If they go around the particle, the dislocation tends to leave traces of itself around the particle called 'Orowan loops', which themselves impede dislocation movement and get bigger and bigger with each passing dislocation.

Work hardening: This is basically working the metal to deliberately introduce more dislocations, and create a forest of dislocations to stop dislocation motion. The metal can be hammered, rolled, bent, d

Part 4: Fast fracture

Fast fracture is when cracks in a material expand rapidly, causing a catastropic failure of the material, even if its below yield point stress. For a crack to grow, there needs to be sufficient stress on the crack. To calculate this critical stress, we consider the work needed for the crack to grow. The work done by the load needs to be greater than the difference between change in elastic energy and energy absorbed at the crack tip (this crap doesn't make no sense.) Equation:

δW ≥ δUel - Gc.t.δa

Gc is the energy absorbed per unit area of crack, with t(delta)a being the new crack area. Gc is the measure of the materials 'toughness', and is how much energy is needed to propagate a crack. A high Gc means the material is tough and cracks have a hard time getting bigger (e.g copper), a low one implies the opposite (e.g ceramics).

Honestly I don't know what i'm talking about in this section.
