Is that taking multiple RAID1+0's and concatenating them? (2 drives go into a single logical drive, and then multiple logical drives are concatenated to create one large logical logical drive?
Sounds groovy. I went from a hardware (DPT) RAID-1+0 to RAID-5 because I needed more space. I don't anticipate a drive dying but I should be able to get another in a couple days if one does happen to yak.
Largely, to keep one program from snatching sensitive information from another program's swap space. Like, for example, passwords that are held in memory. A hostile program running on a box could scan through available swap in search of username/password pairs.
That's one of the reasons your raw partitions aren't given read access to everyone by default.
Now I imagine an exploit could be crafted in which you allocated memory which would be allocated in swap first and then selectively swapped in and scanned...
Okay, let's work this out. Supposing both parents are working 40hrs a week at $5.25 an hour (our minimum wage here)
I don't think I've been to a single factory where the shop workers get minimum, at least not after their three month "probationary" period.
Why would a baby-sitter work for $20/8-hour day when they can go and make $5.25 an hour too?
In my case, the babysitter has 5 kids of her own and it's better/easier/she prefers it to working "out there". She can care for her own kids so tacking on a couple more is no big deal to her. The cut in her pay is far outweighed by her looking after her own kids and on her own schedule.
I admit I thought that babysitters would be a lot more expensive but (at least here) $2.50/hr/kid seems to be a going rate if you provide the food and whatnot. As mentioned in a later post of mine, a guy in the Dallas/Fort Worth area experiences similar rates.
Low unemployment discourages babysitting/lawnmowing types of work since it's easy to get a 'real' job as young as 14 with parental consent) that would leave precisely $0 for food, clothing, medical, and transportation expenses.
I would agree with you. Our unemployment here in Ontario is far worse than yours is (anywhere) in the U.S.
Anyway, I'm just glad that I'm in IT and don't have to deal with wage-slave jobs anymore. It's not a pretty picture trying to make a living without a college degree.
I'm doing pretty good (R&D "engineer" by day, technical / tactical administrator for a fast-growing ISP by night) without a college degree.:-) I admit that I am an exception here though.
None of which is to contradict the basic point that using the TV as a babysitter is a Bad Thing, I'm just saying that the claim that people's standards are too high is not substantiated, at least not for the working classes in the metro-boston area.
I would also imagine that a family with two minimum-wage-ish jobs is also elligible for government aid. When my wife was single and working, she had quite a bit of aid actually and a healthy tax credit to go to daycare for her son (my stepson). Close to 80% if I am not mistaken. However because I "make so much" and because the fact that I have too much debt load (which is entirely my fault, not theirs) doesn't factor into any of their equations, any famillial support by either the provincial (state) or federal governments vanish. I know for a fact that if I was in a low-paying job (probably < $8/hr here in Canada) we would qualify for all kinds of aid.
$20 for 4 hours!!! keep that babysitter! the 17 yr olds on my block want $50 per night minimum and wanted $150 for New years eve.
Yes holidays will be more, but the trick I've found (me NOT being an expert in this field) is to find someone who has a lot of their own kids. Better quality than the 17 year old and not nearly as greedy.
I'm not in a big city so perhaps this helps too, although I was just talking to someone who lives in Dallas/Fort Worth and pays the same rates.
Are you sure that you are $1000 better off? Don't forget to factor in costs of your wife working. She will have to get to work, and will ruin her clothes there. Unless she can walk there, you will be paying a minimum of $2/day in transport. You might also be forced to eat more prepared foods, which are more expensive. If you are forced to help her out with house work, you will have less time for repairning things and so they will break more often had have to be replaced.
Okay maybe not $1000, maybe only $800. Fact is that it's quite a bit more than $0.:-)
Taking your facts:
Clothes: Factory work. Need I say more? Clothes are grubbies.
Vehicle: 2min drive, 20min walk. Depends on her mood/weather/kids. I'll take your $2/day and say $2/week, taking into account gas and wear&tear. That's now $8/mo.
Food: She brings a lunch but may get a prepared snack/meal the odd time: $50/mo.
Home: I just spent the last 4 hours playing with my kids. Housework will Always exist. That's what weekends and after bedtime are for. A friend of mine built an entire second story to his house using just after-work and after-supper time. Took 4 months.
Health: She breathes fuzz from the factory but she does have a mask she can wear if she desires. I don't consider that much more hazardous than the dust bunnies each of us chases around the house.
Neighbours: They are all raising kids and working too. Weekends/suppers... we get thogether then. We (can) help each other repair things or take a trip to the beach together.
Traffic: We're in a town of 5300 and the road to the factory is backroads. Yesterday I counted the stop signs with my son: 4. (about six blocks in total)
I won't argue with you -- yes the quality of living goes down a little, but I look at it this way now: We are knocking down (dumb) debts faster. We're both young (24 and 23) and the kids won't remember these tough times. I actually spend MORE quality time with the little 'uns than I used to and Vanessa doesn't do as much housework because I can do it now. No we don't see eachother as often, but she gets away from the housemommy dementia that tends to plague people who don't have much contact with people outside their kids. I wish she had better work to do but this is good for now.

Linux BIOS
·
· Score: 1
But set-top boxes and other cheap computers probably do.
Those systems usually boot out of flash anyway. What's the point? OpenBIOS tried this and (IMO) has failed. I can't think of a single reason to put Linux into BIOS. 32-bit BIOS? Linux doesn't use it anyway.
Part of the problem is, people are having kids, and they don't give a damn past the birth. There are a lot of affluent folk out there who just want the kids (and the dog) for show-- to prove that they're "good, family people;" there are a lot of less-affluent people that are having kids, and can't afford not to have the TV babysit for them. On the third hand, there are people who are having kids, and just don't give a rat's ass one way or the other.
I'm not quite sure about the whole "not being able to afford a babysitter" part. I work two jobs (okay one and a half, it's still 12-14 hours a day) and my wife just started afternoons at a factory. The kids (4 and 7mos) are at a babysitter from 2:30pm to 6:30pm. That costs us a whole $20 a day (approx $400/mo) to have them looked after by someone who doesn't just plop them down in front of the TV.
With Vanessa (that's my wife) working, she makes about $9.50 an hour breathing fuzz and tying knots (she works at a yarn manufacturer). That means she'll bring home approximately $1600 before taxes every month. Since she's in such a low tax bracket let's say they knock off 15%. That's $1400 a month she brings home, or after daycare (which we wouldn't need if she weren't working) $1000 we didn't have before.
Factory work is damn near everywhere. Yes it's hot, it's awful, it's mind-blisteringly boring... but it's work. And 9 times out of 10 it's above $6/hr ($4 being minimum wage here). I would wager a guess that those moaning that there is no work (especially in America, jeez, every time I'm down there there's signs for help wanted EVERYWHERE) have their standards set too high. Hell even at the shitty factory my wife works at she can be in the highest pay tier in 12 months if she does good.
TV-babysat kids don't save you any money. They cost you a lot in the long run. My kids watch TV at least once every two days (sometimes more than I'd like) but they aren't raised by it. Once my son figured out that TV shows and movies had to end sometime ("Why's it over?!") he had no problem turning off the tube and playing with cars, tormenting his sister, getting dirty outside or getting into my stuff. And the little one is happier trying to figure out how to get Cheerios into her mouth or watching her big brother than she is in any TV show. Maybe we're just lucky or maybe it has something to do with the fact that we don't use the TV as a babysitter.
There's an "urban myth" of a guy stealing power by placing several large coils in his back yard under a primary transfer line... The power company eventaully sued him.
That's no myth.
Where I live there is a great deal of snomobiling and one of the shacks near here had the entire shack lit from a coil of wire wrapped 'round a PVC pipe and put in a tree near a high tension line. They weren't drawing mega amps or anything, just enough for about six 100W light bulbs. The power company found it but nothing bad happnened, just a warning. It was used for a public "building" and hardly any power was drawn. Hell I bet the inspector used the shack himself while out on his sled.:-)
While it is possible to do this, you have a very poor transformer in action and you need to get quite close to the lines. Three phase power lines don't "leak" much because the lines all magnetically cancel each other out and there isn't much left to induce unless you're up close to the line, but that's not safe in the first place.:-)
Plus all the bitching and moaning from AEP about the danger to linemen during maintenance. They claim that they can't be sure that you won't back-feed a line that they have cut for work.
Do what you have to do in industrial situations: provide switchear on the outside of your house with a lockable handle. Make them lock the handle so that if they shut off the line without locking it and die, it's their problem.
Security is solved doing what wireless does now: encryption. Take it a step further (or sideways, depending on how you look at it) and incorporate it right in Layer 2 in hardware, a la GuerillaNet.
Bandwidth is bandwidth. There'll never be enough. Once this progressed to a switched-style network (this is a neat concept in and of itself) it'll alleviate both problems by providing "virtual" point-to-point networking.
I have no idea where you're getting this 1.5k ohms as body resistance. Hell even wet (spit, a great conductor) 1" of skin measures about 800kohms.
First off, you don't say for how much skin. The more skin between the probes, the more resistance.
I've got an ohmmeter on me right this minute and I can't get below 12M on my fingertips. My arms won't even register so it's above 4000Mohms (Fluke 87 III making the measurements).
Also remember that AC resistance and DC resistance are completely different. I may be over 4000Mohms with the ohmmeter but you feel a lot more if you hit yourself with 240VAC. Part of it is skin effect (the AC will travel along the skin, but I imagine 60Hz will penetrate the skin more than straight DC along the surface since it is probably a little more conductive *in* the skin rather than just *on*). I work in industrial power electronics and have been bitten a few times by 575VAC. 90A breakers have a lot of let-through before they trip, and the only reason I'm still here is because the bulk of the current wasn't through me. One of our sales critters got a blast of 4160 when he tried to measure the width of the stacks with a metal measuring tape and my old manager (he's alive, just in a different department) got 4160 across the chest through a power factor capacitor.
Perhaps the weirdest feeling I ever had was when load-testing a 1200A starter. We took a big 50 gallon plastic barrel and filled it with cold water. Then we put the resistor bank in. Our power source was 208 going down to about 8V through one of our big step-down transformers for load testing. a 208:8 transformer would allow us about 5000A of current.
Needless to say the water got pretty warm pretty fast. The neat part was when the president grabbed me and said "Put your arm in it!" When I did so I didn't feel anything at first but when I stuck your arm in the warm water (about 40 degrees C) up to about my elbow, all the muscles in my arm (fingers, wrist, forearm, all of them) started to flex and unflex because of the current flow.
Where was this current flow? From my arm, through my body, through my shoes and to the concrete floor. I was AC-coupled. Very poorly but it was definately one of the weirdest feelings I've ever had. If you know what you're doing it's definately worth doing just to feel it.
Anyway I just meant to comment on your human body model. The most common I've heard is a 1Mohm resistor to ground, not 1500 ohms.
I have to agree with you. I am suspicious of how he hacked them... he provided all other details, why not these?
Now I didn't recognize one of the icons in the systray, I believe it was second from the left. The computer one with some kind of slice thingy. None of those others provide remote access to screen/keyboard. I didn't see any VNC Server there, nada. Now that icon may be a PC/Anywhere icon but I don't use that software and don't recognize it.
Anyway I'd like to see some more proof.
BTW: If this story is true: Great. I hope the spammers have a lifetime of grief bundled into the next couple weeks. They deserve every measure of it. If it's untrue, however, this "Man in the Wilderness" should be subjected to a swimming pool full of double-edged razor blades.
I'll second that. To be honest I don't even use Debian right now, but I think it's important that there is a distribution that remains "pure."
Is there a list somewhere which states which software in which distributions aren't free? I seem to remember hearing about such a beast but can't remember the specifics. I like Slackware for its simplicity but have heard several times now about non-free software in it.
I'm not a Fench History expert, but I was under the impression that the French 35-hour work week came about because of the population density and was set in place to try and allow more people work. Industry averages on the whole just show how the North American worker had bent over and taken it from their employer. I work between 35-40 hours a week with a great salary and perks. I wasn't given the job, I had to work hard for it. Many people are willing to work hard, but not for what they want. Why, I'm not exactly sure.
Dealing with Dumb ISP Admins is a losing battle from the beginning. I work at company that provides Email and domain hosting, and we deal with ISP's that relay spam, flood our DNS and generally are misconfigured. When you contact about half of them, they dont care.
I know it won't help with flooding, but why not disable all access to your network from theirs if "talks break down"? It's not a perfect solution (the perfect solution would be to somehow convince their upline to shut their pipe off until they fix the problems) but it would prevent them from spamming and abusing your services.
I wasn't the first one to throw up the attitude. If you'd care to have read his comment, he was the one who suggested that only the "better" ISPs have either the bandwidth avaiable to handle a flood or the ballsy routers capable of blocking it. I merely responded to his tone.
No, two wrongs don't make a right. But three lefts do and sometimes I don't feel like being the patron saint of patience and grace. I'm not always an asshole, but that doesn't mean I can't be one on occassion.
Additionally, the ISP should either have the bandwidth to handle a DOS attack like that, or the facilities on their router to block it out. If not, you should definately consider a better isp.
Obviously you don't know a whole lot about this.
You can't block smurf attacks at your router. Once the shitstorm hits the pipe it's yours to deal with. If you don't have the bandwidth to handle the smurf traffic, your normal traffic will get bumped in the fray.
Secondly bandwidth is expensive. One of our POPs has a 10mbit link in place to handle 96 dialup customers. Lessee here, 10486kb/s divided into 96*56kbps, or almost 2x the bandwidth we would theoretically require to serve every user if they achieved a true 56000bps connection.
Now along comes Joe Skript Kiddie and his smurf amplification network. Collectively they strike, delivering... oh let's say four good-sized T3 networks' worth of bandwidth to the far end of my 10mbit pipe. There isn't a hope in hell that I'd survive that, even at a 1:2 overcommit (really a 2:1 UNDERcommit. And my bandwidth ratios are pretty decent. Most high speed networks run at a 50:1 or even 100:1 overcommits because bandwidth costs so much.
The solution is to have the smurf traffic blocked BEFORE it hits your upstream pipe, since that way it never gets to clog the connection. Good luck getting your upstream to do that, since it is quite computationally intensive to analyze every packet in the core networks and make intelligent routing decisions. So typically it isn't done.
So much for your fairy-tale concept of how networking works. Perhaps you better go find yourself an ISP with a good VC backing and a 1:1000 overcommit. At least when you don't have to worry about making money you can lose money on every user, along the lines of what amazon.com does.
As for getting the police involved, well, a smurf is virtually untracable, the source addresses points back to the (misconfigured) amplifier network, which is totally innocent, and the packets they receive are forged to come from the victim's computer.
I don't agree.
The "innocent" amplifier network needs to be configured correctly; you said it yourself when you said it was misconfigured.
I'm the technical admin for a smallish (600-user) ISP and while I've never had to deal with this particular problem, I don't think I'd block the user. I'd probably find out what it was they were doing that was so terribly offensive and maybe ask them to stop, but beyond that I have to quote Sig11: "I don't have a solution, but I admire the problem."
Kids learn from the reactions their actions receive. By continually relaxing the threshold at which we begin to enforce the rules, we don't make happy children, we make irresponsible children.
So in essence you're saying "don't spare the rod, beat the child to within an inch of his life so he knows where the lines are"?
Yes I'm blowing your statement out of proportion. That's exactly what the school did with this kid. Calling in the cops, siezeing equipment, whaddafuck?!!? When I was in grade school I got in a pretty decent fight with another kid. He started it (isn't that always the way?), but nevertheless it turned into a big old tumbling brawl and in the end we were both sent home for a day or so. Why didn't they call the cops and haul us off to jail, search our desks for signs of violent nature and generally pull an all-out witch-hunt? Because the administration knew how to dole out punishment appropriate to the infraction.
(perhaps also because things made a little more sense when I was a kid, or that the Internet wasn't around to inspire the media into fightening parents into believing that every fast temper, desire to play with toy guns and "not our kind of person" look was a sign of a psychopath.)
Discipline is very necessary. So is the ability to fit the punishment to the incorrect (re)action. This was not the case with this kid.
Something ain't right here. Seisure of equipment? For writing something that yes, was bad, but was a thousand times better than opening fire?
Maybe someone should go Columbine on that high school* just so the faculty gets it. You can't take away everything. Kids need an outlet to vent. Everyone does. They're taking them away one by one and then wondering what the hell is wrong with America's Youth. Things don't escalate(sp?) by themselves. It takes a continual pressure and a lack of vent. The pressure's there, but there's no vent because no matter what you do you you're chastized and maybe even arrested.
I'm not saying what the guy did was right, I'm commenting more on the fact that the faculty (and parents, wtf is up with "not letting them go to school until he was gone?") completely overreacted.
Once. Just once I'd like to see the faculty deal with the shit these kids have to put up with and not get themselves expelled, arrested or otherwise torn apart by the rules they themselves have set out (or better, not even set out until after the fact). Yes I'm a parent and every day I see this and think to myself "My kids are getting homeschooled, fuck this, I'm not putting my kids though this."
* - No, I don't honestly mean that. Columbine was a horrible horrible tragedy and should have never happened. See, everyone says things when they're mad. It doesn't mean they mean them. Fuck even my four year old does it and understands this concept.

I have no idea where you're getting this 1.5k ohms as body resistance. Hell even wet (spit, a great conductor) 1" of skin measures about 800kohms.
First off, you don't say for how much skin. The more skin between the probes, the more resistance.
I've got an ohmmeter on me right this minute and I can't get below 12M on my fingertips. My arms won't even register so it's above 4000Mohms (Fluke 87 III making the measurements).
Also remember that AC resistance and DC resistance are completely different. I may be over 4000Mohms with the ohmmeter but you feel a lot more if you hit yourself with 240VAC. Part of it is skin effect (the AC will travel along the skin, but I imagine 60Hz will penetrate the skin more than straight DC along the surface since it is probably a little more conductive *in* the skin rather than just *on*). I work in industrial power electronics and have been bitten a few times by 575VAC. 90A breakers have a lot of let-through before they trip, and the only reason I'm still here is because the bulk of the current wasn't through me. One of our sales critters got a blast of 4160 when he tried to measure the width of the stacks with a metal measuring tape and my old manager (he's alive, just in a different department) got 4160 across the chest through a power factor capacitor.
Perhaps the weirdest feeling I ever had was when load-testing a 1200A starter. We took a big 50 gallon plastic barrel and filled it with cold water. Then we put the resistor bank in. Our power source was 208 going down to about 8V through one of our big step-down transformers for load testing. a 208:8 transformer would allow us about 5000A of current.
Needless to say the water got pretty warm pretty fast. The neat part was when the president grabbed me and said "Put your arm in it!" When I did so I didn't feel anything at first but when I stuck your arm in the warm water (about 40 degrees C) up to about my elbow, all the muscles in my arm (fingers, wrist, forearm, all of them) started to flex and unflex because of the current flow.
Where was this current flow? From my arm, through my body, through my shoes and to the concrete floor. I was AC-coupled. Very poorly but it was definately one of the weirdest feelings I've ever had. If you know what you're doing it's definately worth doing just to feel it.
Anyway I just meant to comment on your human body model. The most common I've heard is a 1Mohm resistor to ground, not 1500 ohms.
Better yet, go find yourself a copy of Stevespam, one of the best .mod files I've ever heard!
I guess I'm kinda dating myself here... I was deep into BBSes when this song came out. Wow I kinda miss "Dial attempt #322..." on Telix. :-)
I have to agree with you. I am suspicious of how he hacked them... he provided all other details, why not these?
Now I didn't recognize one of the icons in the systray, I believe it was second from the left. The computer one with some kind of slice thingy. None of those others provide remote access to screen/keyboard. I didn't see any VNC Server there, nada. Now that icon may be a PC/Anywhere icon but I don't use that software and don't recognize it.
Anyway I'd like to see some more proof.
BTW: If this story is true: Great. I hope the spammers have a lifetime of grief bundled into the next couple weeks. They deserve every measure of it. If it's untrue, however, this "Man in the Wilderness" should be subjected to a swimming pool full of double-edged razor blades.
I'll second that. To be honest I don't even use Debian right now, but I think it's important that there is a distribution that remains "pure."
Is there a list somewhere which states which software in which distributions aren't free? I seem to remember hearing about such a beast but can't remember the specifics. I like Slackware for its simplicity but have heard several times now about non-free software in it.
I'm not a Fench History expert, but I was under the impression that the French 35-hour work week came about because of the population density and was set in place to try and allow more people work. Industry averages on the whole just show how the North American worker had bent over and taken it from their employer. I work between 35-40 hours a week with a great salary and perks. I wasn't given the job, I had to work hard for it. Many people are willing to work hard, but not for what they want. Why, I'm not exactly sure.
Dealing with Dumb ISP Admins is a losing battle from the beginning. I work at company that provides Email and domain hosting, and we deal with ISP's that relay spam, flood our DNS and generally are misconfigured. When you contact about half of them, they dont care.
I know it won't help with flooding, but why not disable all access to your network from theirs if "talks break down"? It's not a perfect solution (the perfect solution would be to somehow convince their upline to shut their pipe off until they fix the problems) but it would prevent them from spamming and abusing your services.
I wasn't the first one to throw up the attitude. If you'd care to have read his comment, he was the one who suggested that only the "better" ISPs have either the bandwidth avaiable to handle a flood or the ballsy routers capable of blocking it. I merely responded to his tone.
No, two wrongs don't make a right. But three lefts do and sometimes I don't feel like being the patron saint of patience and grace. I'm not always an asshole, but that doesn't mean I can't be one on occassion.
Additionally, the ISP should either have the bandwidth to handle a DOS attack like that, or the facilities on their router to block it out. If not, you should definately consider a better isp.
Obviously you don't know a whole lot about this.
You can't block smurf attacks at your router. Once the shitstorm hits the pipe it's yours to deal with. If you don't have the bandwidth to handle the smurf traffic, your normal traffic will get bumped in the fray.
Secondly bandwidth is expensive. One of our POPs has a 10mbit link in place to handle 96 dialup customers. Lessee here, 10486kb/s divided into 96*56kbps, or almost 2x the bandwidth we would theoretically require to serve every user if they achieved a true 56000bps connection.
Now along comes Joe Skript Kiddie and his smurf amplification network. Collectively they strike, delivering... oh let's say four good-sized T3 networks' worth of bandwidth to the far end of my 10mbit pipe. There isn't a hope in hell that I'd survive that, even at a 1:2 overcommit (really a 2:1 UNDERcommit. And my bandwidth ratios are pretty decent. Most high speed networks run at a 50:1 or even 100:1 overcommits because bandwidth costs so much.
The solution is to have the smurf traffic blocked BEFORE it hits your upstream pipe, since that way it never gets to clog the connection. Good luck getting your upstream to do that, since it is quite computationally intensive to analyze every packet in the core networks and make intelligent routing decisions. So typically it isn't done.
So much for your fairy-tale concept of how networking works. Perhaps you better go find yourself an ISP with a good VC backing and a 1:1000 overcommit. At least when you don't have to worry about making money you can lose money on every user, along the lines of what amazon.com does.
As for getting the police involved, well, a smurf is virtually untracable, the source addresses points back to the (misconfigured) amplifier network, which is totally innocent, and the packets they receive are forged to come from the victim's computer.
I don't agree.
The "innocent" amplifier network needs to be configured correctly; you said it yourself when you said it was misconfigured.
I'm the technical admin for a smallish (600-user) ISP and while I've never had to deal with this particular problem, I don't think I'd block the user. I'd probably find out what it was they were doing that was so terribly offensive and maybe ask them to stop, but beyond that I have to quote Sig11: "I don't have a solution, but I admire the problem."
Kids learn from the reactions their actions receive. By continually relaxing the threshold at which we begin to enforce the rules, we don't make happy children, we make irresponsible children.
So in essence you're saying "don't spare the rod, beat the child to within an inch of his life so he knows where the lines are"?
Yes I'm blowing your statement out of proportion. That's exactly what the school did with this kid. Calling in the cops, siezeing equipment, whaddafuck?!!? When I was in grade school I got in a pretty decent fight with another kid. He started it (isn't that always the way?), but nevertheless it turned into a big old tumbling brawl and in the end we were both sent home for a day or so. Why didn't they call the cops and haul us off to jail, search our desks for signs of violent nature and generally pull an all-out witch-hunt? Because the administration knew how to dole out punishment appropriate to the infraction.
(perhaps also because things made a little more sense when I was a kid, or that the Internet wasn't around to inspire the media into fightening parents into believing that every fast temper, desire to play with toy guns and "not our kind of person" look was a sign of a psychopath.)
Discipline is very necessary. So is the ability to fit the punishment to the incorrect (re)action. This was not the case with this kid.
So let me see here.
Something ain't right here. Seisure of equipment? For writing something that yes, was bad, but was a thousand times better than opening fire?
Maybe someone should go Columbine on that high school* just so the faculty gets it. You can't take away everything. Kids need an outlet to vent. Everyone does. They're taking them away one by one and then wondering what the hell is wrong with America's Youth. Things don't escalate(sp?) by themselves. It takes a continual pressure and a lack of vent. The pressure's there, but there's no vent because no matter what you do you you're chastized and maybe even arrested.
I'm not saying what the guy did was right, I'm commenting more on the fact that the faculty (and parents, wtf is up with "not letting them go to school until he was gone?") completely overreacted.
Once. Just once I'd like to see the faculty deal with the shit these kids have to put up with and not get themselves expelled, arrested or otherwise torn apart by the rules they themselves have set out (or better, not even set out until after the fact). Yes I'm a parent and every day I see this and think to myself "My kids are getting homeschooled, fuck this, I'm not putting my kids though this."
* - No, I don't honestly mean that. Columbine was a horrible horrible tragedy and should have never happened. See, everyone says things when they're mad. It doesn't mean they mean them. Fuck even my four year old does it and understands this concept.
Actually I shut down POP access for most people because I want the company email on a company server where it gets backed up.
