Sure, before you have a family, you can do bursts of 12-16 hour days. After a week the work product and morale will suffer, but your manager/company has to eat that up.
Once you have a family, it's abusive behavior. Not spending time with family/kids is how the American family and education got fucked up.
You are correct, I should've defined the use case better. I can run X on it fine. I can open multiple terminals under xmonad, ssh to my server and do some administration (although scrolling the terminal window atakes about a second to redraw in full screen). I can even browse the internet with elinks. I can control the GPIO from python.
I'm running it off a 1.85A rated power supply. I have the latest firmware installed. Maybe I was just unlucky with all the keyboard issues, but so far I still have no keyboard that works flawlessly.
As you said, it works well from the command line. If I just keep it running, it does not overheat. The overheating issues showed up when I was cross-compiling some packages. But the heat sinks seem to have fixed that for now.
I'm using the official Raspbian image. When I start LXDE, run Scratch or Midori, I get only 10-20mb free memory.
I quickly abandoned LXDE, installed xmonad, now I have 50-60megs left in the same scenario. While I love xmonad, and it's the only WM I use on all my linux machines, it's not for everyone. But even under xmonad, web browsing is at best super slow with Midori. Chromium is completely useless.
We can get a lot of things to"run" on the RPi, or a machine with 256mb ram. But the real question is, can we get it to run well? Can it do a quick google search? Can it scroll through a webpage with decent speed?
As it stands, I can see the RPi as a faster replacement for Arduino, with a wider range of development tools. But not as a standalone computer to be used in education with X and Scratch.
I have a RPi, but the current hardware version has some major issues.
Not enough memory - As some other commenters noted, the 256mb memory is not enough to run X. Forget web browsing, unless you want to wait minutes to load websites. With Scratch loaded, which is one of the advertised used cases, there's only 10-20mb memory left, with the 240-16 memory split.
Not USB 2.0 compatible - This is a major issue. I tried about a dozen keyboards, most don't work at all, the one that is semi usable repeats keys every so often. The installed fuses only allow ~100mA power, USB 2.0 spec is 500mA. The capacitor installed on the USB power lines is only 47uF, the spec calls for a minimum of 130uF per power line (this makes hot swapping impossible, basically the device freezes if you plug in something while running.) To fix these issues, I added a wire to bypass the fuses and also soldered on some capacitors to fix the hot plug issues. However there still seems to be a driver problem, as my keyboard repeats characters.
Overheating - Mine overheats, even unboxed. It could be that I have a faulty unit. When it overheats, the ethernet stops working. I glued on some heatsinks to get around this.
Maybe the expectations were too high. Maybe this device should be advertised as command line only.
I wish the designers of the RPi would officially admit to the hardware issues, and stop manufacturing the current revision.
We’re encouraged by this progress, but there’s still a long road ahead. To provide the best experience we can, we’ll need to master snow-covered roadways, interpret temporary construction signals and handle other tricky situations that many drivers encounter. As a next step, members of the self-driving car team will soon start using the cars solo (rather than in pairs), for things like commuting to work. This is an important milestone, as it brings this technology one step closer to every commuter. One day we hope this capability will enable people to be more productive in their cars. For now, our team members will remain in the driver’s seats and will take back control if needed.
What are those other tricky situations? How often do they occur? How many times do the google employees have to take thee control those tricky situations? Can we get some more info this?
Parents don't have to understand algebra to make sure that their kids do their homework, understand the subject, and most importantly respect their teachers. If the parent has no clue about a subject, they can still talk to the teacher and make sure their kid is doing well.
Here's a personal experience: my daughter, 5, takes violin lessons. I don't know anything about music. I don't play any instruments. I can't read music, although I've done some research and now I can one note at a time figure out the names of the notes and what string/finger position they refer to on the violin. I can tune her violin, but only with an electronic tuner.
The teacher told us that she had to practice every day with me helping her, so she practices every day and I'm trying my best to help her. The teacher tells me every week what to look out for and what to practice, again, I do my best. She has to listen to prerecorded versions of the pieces, so I have the music available in the car, at home, on my computer and we play them all the time.
Even though I consider myself, her helper, a musical illiterate, she is doing fantastic. She started about 8 months ago, and now she's learning real classical pieces written by real composers.
This journey had its costs, and I'm not talking about the $ we pay for her once a week 30 minute lessons. After the kids go to bed, I often read about music theory or violins. I had to learn how to tighten her bow, make sure that her violin is tuned, and change strings. But the most important thing is that I make arrangements every day to be able to spend an hour with her when she practices.
I forgot to mention above that while I'm Catholic by birth, I don't practice religion, nor do I believe in the Christian God. But that's beside the point.
I cannot prove to you that God exists. But you also cannot prove that God doesn't exist. And, proving pro or con is completely unnecessary. That's not the point of the whole "God" thing.
Believing in God or any Higher Power is a personal thing. It doesn't have to be the Christian God, or any other religion's God. You can make one up for yourself; it can be a group of people, your family, or even a doorknob. It should help and comfort you, especially in situations that are out of your control. Maybe you are just not ready yet?
There is also no reason why science and religion couldn't or wouldn't co-exist. From wikipedia:
Although popular images of controversy continue to exemplify the supposed hostility of Christianity to new scientific theories, studies have shown that Christianity has often nurtured and encouraged scientific endeavour, while at other times the two have co-existed without either tension or attempts at harmonization. If Galileo and the Scopes trial come to mind as examples of conflict, they were the exceptions rather than the rule.
Not all beliefs can be supported by evidence, but are widely accepted. The Big Bang Theory is one of them. Yet it isn't a lie, is it? It's just the best we can do with all that we know.
"I grew up in Chicago's Little Italy neighborhood and was an altar boy (thus, my smart-ass friends called me "pope" because I was such a goody goody and wore a dress in church with the priests. The joke back then was "What kind of sex do priests have? Nun." Of course, that was before we knew that so many priests were serial child rapists and that the church leaders all the way up to the Vatican and including the current Pope Benedict were complicit in protecting those rapist-priests.)"
"Why the hell would anyone do that? His economic position have never, not once, gotten any country in our situation economically better. The economy has improved a lot with Obama policy's. Economically they have worked to get countries in similar situation out of it."
You would need to provide some proof for that. Otherwise it's just your belief, and forcing it on us would, as you said, be some sort of oppression. From what I see, after being on track to add $6 trillion to the deficit in one term, unemployment, housing, manufacturing still pretty bad. Even Obama said a couple of weeks ago, that the economy is not doing good. And all this deficit we are towering up, our children will have to pay back. I can't do that to my kids. Can you?
"please, what great logical leap have you come to the means an increase in ocean sea levels over the next 100years means you can't buy a home on the sea now?"
It seems disingenuous. I don't like our reliance on foreign oil, nor blowing through finite resources, so I drive a hybrid car and don't heat my house with oil. Even though I could afford a gas guzzler and the oil it would guzzle.
"Yes, to keep you fuck twads from infecting other people."
That's not all of it. It's to keep government out of people's personal business. Like give you free speech, so you can call others fuck twads, without worry. (By the way if you are really a dad, might want to watch that.)
"Keep your damn 'beliefs' to yourself and we don't have a problem."
While I'm a Catholic, I don't practice religion. I do not believe that God created the universe. But I don't have any issues with people who do. And be that Christianity, Islam, Judaism, Buddhism, (..insert more here..) religion teaches people to do good. Only a small fraction uses it for evil, but most people mean good.
"of course not, it's an irrational belief, so even another ton of evidences it's wrong won't change their minds"
So what will the discovery of Higgs boson mean to you? Will it really, in all entirety, prove to you exactly how matter was created? Because if not, will it not be just another belief? Will you be able to prove how the universe came to be? If not, how, for you, will it be any better than the guy who believes in creationism?
In all fairness, you could've asked the person you yelled at about his political views, his news outlet preference, his education level, his views on global warming and science in general, before you tagged him an idiot.
Instead, here you are, spewing venom about religion, while you are trying to explain that your nick doesn't mean that you are against religion.
First though, stereotyping is stupid and unfair. I could say that based on your bullying, calling the other guy an idiot, Fox News watcher, global warming denier, I could guess your political views.
Life is not as black and white as you make it out to be. For example I'm a Catholic, have conservative views, tend to agree more with Republicans, watch the O'Reilly Factor every once in a while and will vote for the Republican nominee this year. However in '08 I voted Democrat, studied nuclear physics in college, do believe that the Earth is warming, disagree with our reliance on foreign oil, drive a hybrid car and installed a geothermal heating system in our house. My best friend is gay, I'm not against abortion and my kids play with Asian and African-American kids. I also don't own any guns and there is evolution.
But let's get back to you calling the other guy uneducated. A simple search on wikipedia reveals that Catholics have been historically Democrats, and recently:
"Their party independence continued into 2000, and Catholics became the large religious grouping that most closely reflected the total electorate, ahead of mainline Protestants. 50% of Catholics voted for Al Gore versus 47% for George W. Bush in the very close 2000 election. 52% of Catholics voted for Bush's successful reelection compared to 47% for the Catholic John Kerry in 2004, versus 51% to 48% overall.[4] Barack Obama, who chose the Catholic Joe Biden as his running mate, received 54% of the Catholic vote in 2008 compared to John McCain's 45%, close to the overall 52% to 46%."
Most Jewish people are also Democrats, Republicans hardly get any votes from them.
But I won't do your research on all religions. You should do that, before you call the next guy an idiot.
Al Gore could lose a couple pounds, and if he really believes in the sea levels rising, he should not buy an ocean front mansion nor fly around on his private jet.
And just before I let you go, you should know that discovering Higgs boson will not put a dent in Creationism and there's nothing wrong with people having different beliefs. Religious freedom is what our great country was built on.
This has been done before, albeit under different code names. One, that I lived through, was called communism.
Everyone was equal, had enough money to buy a house, car, weekend house and everything that was produced by the factories and farms owned by the community.
It was working so well, that not even democracy, or elections were needed. It was a well oiled machine.
There were some problems with human shortcomings, like greed for example. The people who wanted more. They became our leaders and we compensated them with bigger houses, bigger cars, the right to travel to the evil capitalist countries and the power to control the military, just to name a few.
There were also people who were not ready for this idyllic way of living. Who pointed out issues with our leaders. They were obviously mentally unfit, and, with great regret, they had to be disposed of. For this purpose a giant meat grinder looking machine was built at the bottom of the Internal Ministry's building, located on the banks of the river Danube. The unfit was quietly ground up into fish food and ejected into the river through a pipe.
There were other experiments, like the Peoples Temple, unfortunately that had to be shut down by dispensing spiked grape flavored Flavor Aid to the members.
If you want to do good for the safety of yourself and others on the road, send that van straight to the junk yard. It's not cool or historic. It's junk.
Instead of burning money on "tech", buy a new, fuel efficient car. I'm actually amazed that nobody's worried about the environment, unless we are talking about global warming.
Next time someone straps a Raspberry Pi onto some object (Dog, Cat, Bat, Grumpy (from Snowwhite)), you'll see it right here. Best thing, it doesn't even have to work.

No, we don't know that there was no sexual assault.
The only way we find out, is if he goes to Sweden and clears his name with the police, or the court.
So don't bother.
Even if you block the filth and facebook, they'll find a way to numb their minds. Like watch youtube.
If you really don't want them to use the school computers for extra curricular web browsing, don't connect them to the internet.

Until then, I'll stick with lasers. Even if it's just b/w.

This board apparently has wifi. That's a great plus. Wifi signal is much easier to find than an ethernet cable.
I don't understand why you think wifi is not good enough for a home server/media player. I watch movies on my laptop over wifi, works awesome.

His work? What do you mean? What change has happened as a result of his work?
Gitmo closed?
Any wars ended?
Conflict in Syria solved?
Government corruption ended?
Greek financial crisis solved?
World peace?
