which link to download gentoo
Would it make you feel better that I used to run FreeBSD and did source builds for my whole system?
I kind of miss the days of having portmaster, ccache, a well made make.conf file, csuping the latest source on current and using clang. Shit was fucking baller, even on my Toshitba craptop computer.
The only thing I don't miss was compiling fuck huge shit like Firefox and LibreOffice.
At the time, I didn't know about xxxterm (now known as Xombrero) and other lighter things. I was also too stubborn to try to mix ports and packages.
Okay, this is a bit troublesome since Intel only had a handful of Intel 64 supported processors from the Celeron D Prescott-256 series (and I'm not even certain if it's from that line... it could be Cedar Mill-512. I'm really hoping it's a Celeron D 347).
If you want to say fuck it, then just install the x86 version of Gentoo. If you want to install the AMD64 version so you can support more than 3 GB of RAM (without using PAE shit), then we need to find more info on your processor.
This might be easier if you install this software so I can get more info:
That or you can open the device manager and find more info on the CPU.
So the main Intel Pentium line is documented for families and models, but I couldn't find it for the Celeron line. ASSUMING they kept the models linear, then I would GUESS that it would be the Celeron D 347, which is Cedar Mill and supports 64-bit instructions and NX-bit.
I should probably mention that if it is the 347, then I once again ASSUME that the BIOS supports it as well or that the CPU came with the board.
Install Speccy (or CPU-Z, but I have never used it, so install at your own risk) and we'll see if we can get some more info about it.
Sorry for all the questions and the info fetch quest. Fucking Intel. Actually, fucking companies in general. They too often fuck around with their model names, internal codes, and marketed names. AMD/ATI will invoke a huge bitchfest from me about their graphics cards.

The device, a thin 2-ounce wand that can be strapped to a backpack or belt loop, connects to a smartphone app via Bluetooth low energy (LE). Slide out the antenna and power on the device and you'll then be able to send messages and GPS coordinates from your smartphone to others connected to a GoTenna. The company offers downloadable, high-resolution offline maps for referencing transmitted location data.

What it does is create a low-frequency radio wave network for its iOS and Android app that can last around 1 mile in skyscraper-filled urban areas, but up to 9 miles in most outdoor situations like hiking and camping. If you're climbing or, say, out skiing, it shoots from 9 miles to as high as 50 miles once you start ascending to higher elevations.

UniFi best AP hands down
A good chunk of the 900MHz spectrum is unlicensed, and it can be used to send all kinds of data, including encrypted data. Unlike MURS.
Ubiquiti is making a 900MHz WiFi transceiver now for long range point to point networking backbones for small companies. No licensing required!
This thread reminded me of this article:
It's no surprise that the NSA likes to have their fingers in every pie and toss in a shitton of salt (see NIST crypto standards and this link: http://cryptome.org/nsa-sabotage.htm ), so seeing this article kind of makes me feel as though it is a possibility, as tinfoil hat as that sounds.
Anyways, the comments are a decent silver mine. Enjoy the read.

Basically, OpenBSD is known for being a minimal OS that aims for maximum security by having proactive security practices.
As this is an OS, they have support for hardware. OpenBSD, like many other OSs, splits up support based upon the CPU architecture and sometimes based upon a particular popular platform ( http://www.openbsd.org/plat.html ).
Octeon is a version of a MIPS64 processor that the EdgeRouter Lite uses.

Hey! I work for the company that does crash attenuation and a lot of parts for the cirrus planes! Pretty cool seeing the testing in action.
General discussion, starting with a dilemma:
I'm taking a break from my bachelors degree, one that might last for another one or two years. I've been offered a full-time job that seems like a good fit for me, but isn't really related to my major. (The job is in Appliance Installation, and my major is in Manufacturing Engineering.)
I have bupkiss skilled labor experience, so I'm feeling pretty lucky about this offer. At the same time, I feel like I should do as much as I can in pursuit of the degree, seeing as I've already been in school for a while and racked up about 20k in debt.
How advantageous is it that I work a job related to my major? Would it be worthwhile to hold out for a factory job?
As said in >>6612
>I say keep your nose to the grindstone, it will pay off in two or three more years.
You ever go hiking, and decide to take a break? You sit down for a minute or two to take a rest, and when you go to get back up, your legs feel much more stiff and tired than when you sat down?
Engineering school is kind of like that. Ya, it can be shitty and tiring at times, but if you take a break too early you might just not come back, and if you do, it will be that much harder to get up to speed again.
If your engineering program has work terms built in to it, take them, but at an an accredited engineering firm doing engineering work, or with a professor doing research. Don't settle for less; it will be a waste of your time. I don't know if they have an equivalent to a P.Eng certification in the 'States, but if they do; time spent on a work term might count towards getting it.
Another reason to hold off until you can get an engineering job on a work term is that employers are going to look at your past work experience with other engineering firms. You might be the best goddamn appliance installer to have ever existed, but they wont care. Depending on your area and how the local economy is doing, you are going to need what ever advantage you can get over fellow classmates (and those from other schools) to get that post graduation job.
For the record, I too am an engineering student, studying materials engineering.
Already interviewed there for an assembly position. I didn't get the job.
Like I said: my resume is not good. Last job was dishwashing at minimum wage, no real assembly experience. I'm not sure I'm actually qualified for any kind of engineering-related work, and I don't see myself as a competitive applicant for well-paying production jobs.
The break from college has more to do with money than fatigue. Before, my parents were helping out with tuition, but my mothers' firm stopped paying her over the summer, so I couldn't return to school this fall like we'd planned. From what they're telling me, I can't go back unless I pay for it myself, or Mama Opforian gets another cushy job in the next 11 months. Either way, I'm expected to pay up, and the job I have now barely pays for gas.
I was also taking classes in community college up until august this year, so It's not like I've been lying around.
Basically, I realize this job isn't going to move me forward, but I have little confidence I can secure a paying job that does.
There are creative ways to pad a resume. Apply for a tax number, that was any gaps in your employment history can be explained away with "I was running a private business."
Semi-related to the OP, but I've been quietly contemplating going back to school for a STEM related degree ever since I graduated with a History/PoliSci degree two years ago. I did extremely well, but I decided against grad school, since the academic job market for Historians actually makes law school look promising by comparison. So far, the math hasn't been nearly as tough as I expected it to be, but I'm still only grazing the surface first year calculus, and I'm self-taught, so there are probably more than a few gaps in my knowledge that I'm not really aware of. I still have about $25k in student debt to pay off, and I've already used up 4 semester's worth of Pell Grants and subsidized loans, so financially speaking, getting another degree within the next few years just isn't in the cards. But looking farther out, maybe within 5 years, I'm looking more and more at Computer Science or Electrical Engineering. Is this just craziness on my part? I know you guys are mostly hard-headed realists, so any sane, sober (or even harsh) advice you might be willing to provide would be sincerely appreciated.
Just so we're covering our bases here, posting this to clarify and perhaps reassure some of you reading this thread right now. Not everyone thinks that griping about being a fucking engineer in college and shit is anything. It's your life, live it how you need to. Fuck school, fuck the corporate world, do what you have to.
Not sure what board this should go on but how difficult would it be to build a decent (let's say accurate at 100m) rifle out of a nail gun?
So they had those available in addition to flechettes?
That's very interesting, I've heard of these flechette rounds before, but they mostly seemed to have disappointing flight characteristics. It seems like half the battle is getting the sabot casing to separate as intended, and then getting the sabot to orient quickly enough that it has acceptable accuracy. I'm not really a STEM guy, so pardon me if I come off as naive, but are there any design programs that can model aerodynamic performance?
I wonder what the limit on length/diameter for something like this would be? The ones in FEAR are big enough to nail people to the walls.
OpenFOAM is free but kind of shitty and hard to work with
MATLAB can be scripted to some basic stuff
Really though the math on flechettes is simple enough that you could probably do most of it on paper.
I know Seraph and PvtCaboose have printers, and you should check out http://www.operatorchan.org/st/res/796.html if you haven't already.
I have recently joined the 3D printer owners fraternity after a couple of years of casual interest. I got a used perfectly well tuned and barely broken-in ORD Bot Hadron with EZ Struder, Mk V J Head and bucket full of filament and spare parts off of craigslist for, get this, $500. The guy was a retired computer coder and lived in the nicest neighborhood I'd ever seen but he and his wife were packing up to move to a smaller house since the kids were moved out. He just wanted it gone even at a loss.
I lucked out on the deal.
The ORD Bot is an open-source design built around with Makerslide with common M5 and M8 components. Instead of linear bearings, double-bearing Delrin rollers ride on the Makerslide rails. So far it's been rock-solid for me, as good as you could possibly expect modern aluminum extrusions and a solid metal frame to be.
>I'm not sure if that counts as an AOW
If you go to the guy's website you'll see it actually has a rifled barrel, hilariously short albeit but it's there.
Maybe I missed it, but where is the metal permanently attached to the firearm that is required by the undetectable firearms act (if this is indeed a firearm)?
That would seem an excellent question. Looking at the act itself though I think he might still be alright, it doesn't say anything about "metal permanently attached", just that it has to be detectable by modern standards. I think the use of steel bolts and AR FCG parts likely makes this thing detectable enough to be legal. http://www.gpo.gov/fdsys/pkg/STATUTE-102/pdf/STATUTE-102-Pg3816.pdf

In college, it wasn’t rare to hear a verbal battle regarding artificial intelligence erupt between my friends studying neuroscience and my friends studying computer science.
One rather outrageous fellow would mention the possibility of a computer takeover, and off they went. The neuroscience-savvy would awe at the potential of such hybrid technology as the CS majors argued we have nothing to fear, as computers will always need a programmer to tell them what to do.
Today’s news brings us to the Neural Turing Machine, a computer that will combine the way ordinary computers work with the way the human brain learns, enabling it to actually program itself. Perhaps my CS friends should reevaluate their position?
The computer is currently being developed by the London-based DeepMind Technologies, an artificial intelligence firm that was acquired by Google earlier this year. Neural networks — which will enable the computer to invent programs for situations it has not seen before — will make up half of the computer’s architecture. Experts at the firm hope this will equip the machine with the means to create like a human, but still with the number-crunching power of a computer, New Scientist reports.
In two different tests, the NTM was asked to 1) learn to copy blocks of binary data and 2) learn to remember and sort lists of data. The results were compared with a more basic neural network, and it was found that the computer learned faster and produced longer blocks of data with fewer errors. Additionally, the computer’s methods were found to be very similar to the code a human programmer would’ve written to make the computer complete such a task.
These are extremely simple tasks for a computer to accomplish when being told to do so, but computers’ abilities to learn them on their own could mean a lot for the future of AI.

We’ve been hearing for decades about the complex intelligence of plants; last year’s excellent New Yorker piece is a good place to start, if you want to learn more about the subject. But a new study, conducted by researchers at the University of Missouri, managed to figure out one new important element: plants can tell when they’re being eaten, and they don’t like it.
The word “intelligence,” when applied to any non-human animal or plant, is imprecise and sort of meaningless; research done to determine “intelligence” mostly just aims to learn how similar the inner workings of another organism is to a human thought process. There’s certainly nothing evolutionarily important about these sorts of intelligence studies; a chimp is not superior to a chicken just because chimps can use tools the same way humans do. But these studies are fascinating, and do give us insight into how other organisms think and behave, whatever “think” might mean.
This particular study was on the ever-popular Arabidopsis, specifically the thale cress, easily the most popular plant for experimentation. It’s in the brassica family, closely related to broccoli, kale, mustard greens, and cabbage, though unlike most of its cousins it isn’t very good to eat. This particular plant is so common for experiments because it was the first plant to have its genome sequenced, so scientists understand its inner workings better than almost any other plant.
The researchers were seeking to answer an unusual question: does a plant know when it’s being eaten? To do that, the researchers had to first make a precise audio version of the vibrations that a caterpillar makes as it eats leaves. The theory is that it’s these vibrations that the plant can somehow feel or hear. In addition, the researchers also came up with vibrations to mimic other natural vibrations the plant might experience, like wind noise.
Turns out, the thale cress actually produces some mustard oils and sends them through the leaves to deter predators (the oils are mildly toxic when ingested). And the study showed that when the plants felt or heard the caterpillar-munching vibrations, they sent out extra mustard oils into the leaves. When they felt or heard other vibrations? Nothing. It’s a far more dynamic defense than scientists had realized: the plant is more aware of its surroundings and able to respond than expected.
There’s more research to be done; nobody’s quite sure by what mechanism the plant can actually feel or hear these vibrations, and with so many plants out there, we’re not sure what kind of variation on this behavior there is. But it’s really promising research; there’s even talk of using sound waves to encourage crops to, say, grow faster, or send out specific defenses against attacks. Imagine knowing that a frost is coming, and being able to encourage plants to fruit faster by simply blasting them with mu

>An upgrade would boost that to 60 million amps, enough to push the project's fusion scheme well into or at least very close to the realm of commercial viability. A 2012 paper presenting results for simulated Z-Machine fusion conditions at 60 million amps concluded, "For a drive current of 60 MA the simulated gain exceeds 100, which is more than adequate for fusion energy applications."
So close fellas!
Remember that with fusion, "net gain" does not mean useful electricity right off the bat.
"Breaking 100" only means you get more energy out of the reaction than you put into it. More ENERGY - meaning heat, light, free electrons, etc.
The next big fusion hurdle will be finding a way to convert the extra energy into useful electricity via a system. Remember that most ways of converting heat etc. to electricity are piss poor inefficient in the grand scheme of things.
The only real breakthrough here is that the fusion reactor could sustain itself without needing more energy put in from the outside.

And if you want a helicarrier, you damn well better turn your SCIENCE! up to 11. Video related (WARNING: Maths ahead).
Eh, carriers arent made to be light. Im sure they can use aluminum and use about half of it too. Im fairy sure they're actually a lot heavier than necessary for structural integrity because of armor. Supersonic helicopter blades exist, so we can double the speed and at this point we might as well add some more rotors.
Only question is, how are we going to power the thing?
Nevermind that the Helicarrier's running what are basically turbofans, not rotors. There's a bit of an efficiency boost since there's no aerodynamic "spill" over the end of the rotor blade, it's al kept inside the duct.
I'm not saying it's entirely plausible, but it's not nearly as impossible as lifting a Nimitz-class carrier with four Blackhawk rotors.
Goats learn how to solve complicated tasks quickly and can recall how to perform them for at least 10 months, which might explain their remarkable ability to adapt to harsh environments, say researchers at Queen Mary University of London.
Writing in the journal Frontiers in Zoology today, the scientists trained a group of goats to retrieve food from a box using a linked sequence of steps; first by pulling a lever with their mouths and then by lifting it to release the reward.
The goats' ability to remember the task was tested after one month and again at 10 months. They learned the task within 12 trials and took less than two minutes to remember the challenge.
"The speed at which the goats completed the task at 10 months compared to how long it took them to learn indicates excellent long-term memory," said co-author Dr Elodie Briefer, now based at ETH Zurich.
Before each learning session, some of the goats had the opportunity to watch another goat to demonstrate the task.
Dr Briefer added: "We found that those without a demonstrator were just as fast at learning as those that had seen demonstrations. This shows that goats prefer to learn on their own rather than by watching others."
This is the first time that scientists have investigated how goats learn complex physical cognition tasks, which could explain why they are so adaptable to harsh environments and good at foraging for plants in the wild, for example.
Co-author Dr Alan McElligott from Queen Mary's School of Biological and Chemical Sciences, commented: "Our results challenge the common misconception that goats aren't intelligent animals - they have the ability to learn complex tasks and remember them for a long time.
"This could explain why they are so successful in colonising new environments, though we would need to perform a similar study with wild goats to be sure."

Goats are notorious for being a baffling mix of curiously clever and goddamn fucking retarded, as anyone who gets one will quickly learn.
They are good at learning from each other. If there is a means to escape their fencing, they WILL find it, and as soon as one does, every other goat will instantly know how as well.
They will find every hole and foothold possible. Think your fence is high enough? They'll climb on something nearby, and then jump it. They rest will quickly follow suit because fuck you that's why.
They also have a penchant for getting into trouble. One particular thing you should keep in mind when getting a goat is they see windows as openings to jump through, and will very much do so.
While they are also known for eating anything they can, this is only partially true. They actually use their sense of taste as a way of examining something, much like a baby. They still will end up consuming a lot of bad things if you are negligent in your care of goats.
Goats are about as cool (and downright useful if you have a large yard with difficult to control plants species) as any of the Bovidae get.
